Water is the primary need for all vital life processes. Water itself is an environment, which support large number of organisms. However, it is highly affected due to increased population, industrialization and unplanned urbanization that makes pure water scanty to human beings. Day by day, water bodies are being highly contaminated and are becoming biological deserts. At the same time, the quality of standing water is becoming more and more unfit for humankind due to unwise use, negligence and mismanagement. The quality of life is linked with the quality of environment, hence biological components of fresh water depend solely on better physico-chemical conditions, and therefore, analysis of physic-chemical parameters of water is essential. The present study was conducted at two different stations in the Rangawali Dam, from tribal area. Samples were collected between June 2007 and May 2009 on a monthly basis and evaluated quantitatively. The study carried out for two years included following physicochemical parameters of the water samples. The regional climate at the site of study is distinctly marked in to three seasons, namely Monsoon (June to September) winter (October to January) and summer (February to May). The physico-chemical parameters like Rain Fall , Atmospheric temp, Water temp, pH, Dissolved Oxygen, Dissolved carbon dioxide, Calcium, Magnesium Chlorides and Sulphates were studied on seasonal basis, since the climatic changes seem to influence the ecological factors, and physicochemical parameters.

Urban stormwater lakes in cold regions are ice-covered for substantial parts of the winter. It has long been considered that the ice-covered period is the “dormant season,” during which ecological processes are inactive. However, little is known about this period due to the historical focus on the open-water season. Recent pioneering research on ice-covered natural lakes has suggested that some critical ecological processes play out on the ice. The objective of this study was to investigate the active processes in ice-covered stormwater lakes. Data collected during a two-year field measurement program at a stormwater lake located in Edmonton, Alberta, Canada were analyzed. The lake was covered by ice from November to mid-April of the following year. The mean value of chlorophyll-a during the ice-covered period was 22.09% of the mean value for the open-water season, suggesting that primary productivity under ice can be important. Nitrogen and phosphorus were remarkably higher during the ice-covered period, while dissolved organic carbon showed little seasonal variation. Under ice-covered conditions, the total phosphorus was the major nutrient controlling the ratio of total nitrogen to total phosphorus, and a significant positive correlation existed between total phosphorus and chlorophyll-a when the ratio was smaller than 10. The results provide preliminary evidence of the critical nutrient processes in the Stormwater Lake during the ice-covered period.
Study of Seasonal Variations in Oxygen Consumption of Estuarine Clam, Meretri...ijtsrd
The estuarine clam, Meretrix meretrix was exposed to predetermined seasonal sublethal and lethal concentrations of CdCl2, 2½ H2O for 96 hrs. Experiments were conducted during summer, monsoon and winter by keeping control group of clams. Estuarine water parameters like temperature, pH, salinity, rainfall and dissolved oxygen were recorded. In the present study, it is found that, it has significant influence on rate of oxygen consumption and toxicity of cadmium chloride. During summer, clams from LC0 and LC50 group were treated with 1.1ppm and 1.8 ppm respectively. During monsoon LC0 and LC50 group were treated with 1.6 ppm and 2.0 ppm respectively. During winter clams from LC0 and LC50 group were exposed to 1.4 ppm and 2.1 ppm cadmium chloride respectively. During summer, as compared to control group, there were 3.83, 17.04, 16.77 and 10.63 increase in oxygen uptake at the end of 24, 36, 48, and 60 hrs. There were 0.35, 4.97 and 21.75 decrease at the end of 48, 72, 84 and 96 hrs. Moreover, similar trend of oxygen consumption was observed in LC0 and LC50 .group of clams in winter and monsoon season. During monsoon and winter clams from control group showed similar trend of oxygen uptake with less significant fluctuations. Clams from control group and LC0 and LC50 group showed less oxygen consumption during monsoon than summer and winter.

Creek water carries both domestic and commercial wastewater consequently draining organic and inorganic pollutants to coastal water. The present study dealt on the environmental risk assessment of creek water stretching in Macabalan-Cagayan de Oro, Philippines. Selected physicochemical analyses of water samples were carried in both temporal and spatial variations. Risk quotient (RQ), water quality index (WQI), and brine shrimp lethality test (BSL) was employed to draw environmental risk estimate. Overall, dissolved oxygen (DO) concentrations were below the standard set regardless of temporal and spatial variations. Both RQ and WQI showed good statuses on creek water quality despite the low DO. The BSLT similarly indicated a higher concentration for LC50 to be established. The study was preliminary and further monitoring may be essential.

The challenges of river water quality management are so enormous, due to the unpredictive modes of contamination. Monitoring different sources of pollutant load contribution to the river basin is also quite tasking, resulting to laborious and expensive process which sometimes lead to analytical errors. This study deals with the assessment of the physico– chemicaland bacteriological parameters of water samples from River Amba during the period of August 2017 to January 2018 and developing regression models. Water quality Parameters such as Temperature, Turbidity (NTU), Suspended solids (mg/l), Colour, Total solids, Total dissolved solids, Electrical conductivity (μs/cm), pH, Hardness, Chemical Oxygen Demand, Dissolved Oxygen (DO), and Total Coliform were obtained and compared with water quality standards. The results of the water quality analysis of the study in comparison with drinking water quality standard issued byWorld Health Organization(WHO) and National Agency for Food and Drug Administration Control (NAFDAC) revealed that most of the water quality parameters were not adequate to pronounce the water potable. Hence adequate water treatment processes should be employed to make the water fit for consumption and other domestic uses. Statistical analysis was done, in which the systematic correlation and regressionanalysis showed a significant linear relationship between different pairs of water quality parameters. The highest correlation coefficient between different pairs of parameters obtained is (r = 0.999), resulting from the correlation between TS and SS. Multiple regression analysis was also carried out and regression equations were developed. It was observed that the parameters studied had a positive correlation with each other.
Rainy seasonal analysis of Physico-chemical parameters of Mukungwa River at N...Agriculture Journal IJOEAR
Water availability and quality are important factors that determine not only where people can live, but also the quality of life. The Mukungwa river is affected by rainy season especially at Ngaru point before discharge in Nyabarongo river, where its physico-chemical properties are seasonally changed. This may cause serious problems on all forms of life in the river. Objective of this work was to assess the impacts of rainy season on physico-chemical properties of Mukugwa River before discharging into Nyabarongo River at Ngaru. The parameters such as pH, temperature, turbidity, electric conductivity, total dissolved solids (TSS), phosphates, nitrates, and ammonium were monitored in three rainy seasons: April, 2012; October, 2012 and May, 2017 respectively. In this research, pH, temperature, electric conductivity were analyzed in situ using multifunction pH-meter and others parameters, were analyzed in laboratory using electrometric, volumetric, turbidity tube and colorimetric methods. The measured values for each parameter in three seasons were analyzed using MS Excel, and then compared to their international standards for surface water delivered by World Health Organization (WHO). The findings showed high variation of TSS (134mg/l, 178mg/l, and 582mg/l), turbidity (322NTU, 317NTU and 1560NTU) and ammonium (0.498mg/L, 0.536mg/L and 0.78mg/L) in three rainy seasons assessed. The quality of Mukungwa River needs prevention measures in order to control its pollution by erosion.

Trace Metals Concentration in Shallow Well Water in Enugu Metropolispaperpublications3
Abstract: This work assesses the concentration of heavy metals in Enugu Municipal well-water considering the fact that some Enugu inhabitants depend on well-water as their major source of water supply. Water from twenty four (24) different hand dug wells from six locations were investigated for Zn, Cu, Pb, Mn, Cd, and Fe using Atomic Absorption Spectroscopy (AAS). The result of the study expressed as the means and standard deviations were compared to WHO and EU standards for drinking water, and it was found that well waters from Iva-Valley and Uwani areas suffer from Cd and Mn pollution. The remaining four locations (Emene, Asata, Abakpa Nike and Achara Layout) were all free from Cd and Mn pollution. Cu, Zn, Fe and Pb concentrations were either completely absent or below world threshold limits at all the locations.

In this case study, factor analysis was applied for evaluation of temporal/spatial variations in the
groundwater quality of Aravakurichi block, Karur district, Tamil Nadu, India. This statistical technique was
employed for the better interpretation of large complex water quality data set obtained from twenty five
groundwater locations in four seasons during the year 2012. The water samples were characterized for the
physico-chemical parameters such as pH, total alkalinity, electrical conductivity, total hardness, calcium ions,
magnesium ions, total dissolved solids, fluorides, chlorides and sulphates. Factor analysis indicated four factors
initially and when rotation of the factor axis was executed, it yielded two factors with clear indication of high
loadings for some variable and low loadings for others, facilitating data interpretation in terms of original
variables. Overall, this case study demonstrated the effectiveness of factor analysis to identify marker variables
for assessing the chemistry of groundwater besides earmarking representative sampling stations to undertake
suitable water quality management in a shortest possible time.

The quality of any body of surface or ground water
is a function of either both natural influences and human
influences. Without human influences water quality would be
determined by the weathering of bedrock minerals, by the
atmospheric processes of evaporation, transpiration and the
deposition of dust and salt by wind, by the natural leaching of
organic matter and nutrients from soil, by hydrological factors
that lead to runoff, and by biological processes within the aquatic
environment that can alter the physical and chemical
composition of water. Declining water quality has become a
global issue of concern as human populations griesrow, industrial
and agricultural activities expand, and climate change threatens
to cause major alterations to the hydrological cycle.

ABSTRACT- An attempt was made to study the increasing organic pollutants in the 'Syama Kunda', a holy water reservoir of religious importance in District Mathura, India. Various key physico-chemical parameters of water of the reservoir were tested over an entire year from January 2016 to December 2016. The populations of some test organisms were also noted from the same water samples. A correlation was tried to develop between the degree of pollution load and fluctuations in the population of the test organisms. It was found that the ‘Syama Kunda’ reservoir is grossly polluted. The level of pollution becomes the most severe in summers. The test organisms, especially Arcella and Paramecium spp. exhibited a severe negative trend with the rise in pollution load.

Groundwater samples were collected from 91 different locations in the Vaippar basin, Tamil Nadu, India. Groundwater quality data for the period of 30 years (1983 to 2013) of both pre-monsoon and post-monsoon periods were used to analyze the groundwater quality aspects of the Vaippar basin. The physico-chemical parameters such as Total Dissolved Solids (TDS), pH, HCO3-, Ca2+, Mg2+, Na+, K+, SO4-, NO3- and Cl have been analyzed to determine the geological and non-geological source of contamination. An overall hydrogeochemical analytical study using Electrical Conductivity, Sodium Adsorption Ratio (SAR), Sodium percentage (Na%) and Residual Sodium Carbonate (RSC) values reveals that most of the groundwater samples collected from the study area are suitable for drinking, irrigation, and industrial purposes.

Geologically, it is underlain mainly by Peninsular gneisses of Archean age followed by Gulcheru and Vemapalli
formations comprising quartzites, conglomerates, dolomites and shales. Major geomorphic units are
denudational hills, residual hills, pediments, pediplains, structural hills and valleys. The study area experiences a
semiarid climate. Physicochemical parameters viz., pH, total hardness, calcium, chloride, total dissolved solids,
fluoride were analyzed. Most of parameter show higher value than permissible limit in pre and post monsoon.
Further, a moderation in water quality was observed after the monsoon season, which can be attributed to a
possible dilution due to groundwater recharge People dependent on this water may prone to health hazard.
Therefore some effective measures are urgently required to enhance the quality of water in these areas

Geologically, it is underlain mainly by Peninsular gneisses of Archean age followed by Gulcheru and Vemapalli
formations comprising quartzites, conglomerates, dolomites and shales. Major geomorphic units are
denudational hills, residual hills, pediments, pediplains, structural hills and valleys. The study area experiences a
semiarid climate. Physicochemical parameters viz., pH, total hardness, calcium, chloride, total dissolved solids,
fluoride were analyzed. Most of parameter show higher value than permissible limit in pre and post monsoon.
Further, a moderation in water quality was observed after the monsoon season, which can be attributed to a
possible dilution due to groundwater recharge People dependent on this water may prone to health hazard.
Therefore some effective measures are urgently required to enhance the quality of water in these areas
This study highlighted the pernicious elements present in the sediment and water of Aba River.Upstream and downstream sediment and water samples were collected at four different sampling points along Aba River. The samples were analyzed for the presence of heavy metals. Microbiological analyses were carried out using the spread plate method and bacterial and fungal isolates identified using standard methods. Analyses were carried out to determine the physicochemical properties using standard methods. Results obtained showed the presence of heavy metals in sediment physicochemical parameters in the ranges of turbidity (11.00-15.00NTU), conductivity (1.80-3.09µS/cm), BOD5 (2.10-5.05mg/g), COD (19.50-25.60mg/g), TDS (610-840mg/g), pH (7.20-7.55), temperature (29.00-30.10°C), K (7.16-9.15mg/g), Na (3.53-4.85mg/g), Mg (4.30-5.40 mg/g), Cr (0.04-0.20mg/g), Zn (0.21-0.35mg/g), Fe (3.75-4.42mg/g), Al (1.05-1.25 mg/g), SO42- (11.75-13.11mg/g), PO42- (0.30-1.1 1mg/g), NO3 (6.35-8.16mg/g). Water physicochemical parameters were in the ranges of turbidity (3.30-9.00mg/l), conductivity (0.63-1.80mg/l), BOD5 (1.72-2. 50mg/l), COD (14.39-22.40mg/l), DO (2.95-5.6mg/l), TDS (245-556mg/l), pH (6.90-7.50), temperature (28.50-30.50°C), K (0.001-6.55mg/l), Na (1.25-3.55mg/l), Mg (1.50-4.60mg/l), Cr (0.00-0.15mg/l), Zn (0.01-0.13mg/l), Fe (1.15-3.95mg/l), Al (0.001-1.12mg/l), SO42- (11.75-13.30mg/l), PO42- (0.30-1.11mg/l), NO3 (6.35-8.16mg/l). The mean bacterial counts recorded for the different sampling points were higher in the wet season for sediment samples (0.97-6.00 x 106 cfu/g) than in the dry season (2.15-5.85 x 106 cfu/g), also the mean bacterial counts recorded for water samples were higher in the wet season (1.41-2.95 x 106 cfu/ml) than in the dry season (1.31-2.39 x 106 cfu/ml). The diversity of microorganisms isolated and identified were; Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Salmonella typhi, Shigella dysentariea,, Bacillus cereus, Enterobacter aerogenes, Enterococcus faecalis, Serratia mercences, Micrococcus luteus, Micrococcus roseus, Aspergillus niger, Penicillium notatum, Saccharomyces cerevisae, Fusarium poae, Rhizopus stolonifer, Rhizopus nigricans, Mucor sp. The distribution of these organisms varied between samples, distance and season. The high level of both microorganisms and heavy metals suggest that the anthropogenic activities in the River could cause health menace to users and therefore should be put to check regularly.
Environmental risk assessment of Macabalan creek water in Cagayan de Oro, Phi...Innspub Net
Creek water carries both domestic and commercial wastewater consequently draining organic and inorganic pollutants to coastal water. The present study dealt on the environmental risk assessment of creek water stretching in Macabalan-Cagayan de Oro, Philippines. Selected physicochemical analyses of water samples were carried in both temporal and spatial variations. Risk quotient (RQ), water quality index (WQI), and brine shrimp lethality test (BSL) was employed to draw environmental risk estimate. Overall, dissolved oxygen (DO) concentrations were below the standard set regardless of temporal and spatial variations. Both RQ and WQI showed good statuses on creek water quality despite the low DO. The BSLT similarly indicated a higher concentration for LC50 to be established. The study was preliminary and further monitoring may be essential.

ABSTRACT- Three decades data (1984 – 2015) was used to study the effect of surface water temperature, pH, dissolved
oxygen, nitrate, phosphate and silicate on chlorophyll a concentration in three water bodies meant for fish culture (locally
known as Bheries) in East Kolkata Wetlands. The data revealed significant spatio-temporal variations (p < 0.01). The
increasing trend of temperature, nitrate and phosphate reflects the effect of intense urbanization at local level. The
pronounced variation of dissolved oxygen and chlorophyll a (decreasing trend) may be attributed to increased load of
sewage in the selected water bodies, which has posed an adverse impact on the phytoplankton standing stock as revealed
through decreasing chlorophyll a trend.

Fluctuation of NO3-N and PO4 Elements in The Traditional Pond Area at TidesIJAEMSJORNAL
Traditional pond technology depends on nature in management, such as filling and disposal of pond water utilizing the time of low and high tides. The food for traditional pond technology comes from nature. The availability of nutrients such as N and P greatly determines the productivity of pond. The study was aimed to determine the fluctuations of N and P elements in traditional pond areas at tides. This research was conducted with purposive sampling method and laboratory analysis for several water parameters. The results showed that pH ranged from 7 to 8 both at low tide and high tide. The average value of nitrate (NO3) from five locations was extended from 0.106 to 1.495 mg/l. The value of silica (Si) ranged from 5,287 to 10,876 mg/l in low tide. Orthophosphate at low tide ranged from 0.027 to 0.090 mg/l, the highest value was in the coast station and the lowest was in the sea station. Whereas the value of nitrate (NO3) and orthophosphate in high tide ranged from 0.830 to 1.495 mg/l and 0.039 to 0.090 mg/l. Nutrients were abundant enough to support the growth and development of primary producers. So, the waters in this region include fertile waters.
Study of Physicochemical Properties of Freshwater Body Located at Madhepura D...ijtsrd
In order to better understand the current situation and plan for its future use, the current research examines the seasonal fluctuations in some significant physico chemical parameters and biological investigations of the three rural ponds in Madhepura, Bihar. The data gathered during different seasons summer, winter, and rainy study showed that the studied parameters were within acceptable limits for fish culture and the stocking should be done in accordance with the productivity of the water. Yet, a statistical examination of the data shows that the physicochemical characteristics of certain ponds were responsible for significant environmental benefits. Our study emphasizes the importance of community involvement and effluent disposal education. Our investigation of the ponds BOD shows that they are somewhat polluted, which has to be fixed in the future for higher productivity.

Considering the effects of chemical herbicide application, biomarkers have
now become more widely considered for controlling weeds. Allelopathy demonstrates
the potential for this through the release of trace elements from decomposable plant
leaves, seeds, stems and strains. In order to investigate the effects of aqueous extract
of sunflower on the germination and morphological characteristics of Rumex acetosa,
Lepidium draba and Convolvulus arvensis seedlings as three common weeds in sugar
beet fields, a research experiment was carried out in the laboratory of Islamic Azad
University, Neishabour, in 2016 as a factorial in the form of completely randomized
design with four replications. The experimental treatments were aqueous extract of
sunflower (zero, 25%, 50%, 75% and 100%), the type of weed in three levels (Rumex
acetosa, Lepidium draba and Convolvulus arvensis), respectively. The results showed
that the highest percentage and rate of germination were observed in non-use of
sunflower extract (irrigation with distilled water), which in Rumex acetosa 97 and 33
percent were higher respectively, in comparison to Lepidium draba and Convolvulus
arvensis. In the study of stem fresh weight, fresh and dry weight of roots, it showed
that the field bindweed plant was more resistant compared to Rumex acetosa,
Lepidium draba. The lowest germination and seedling traits were obtained in 100% of
sunflower aqueous extract, which affected the weeds of the Ivy and Blacks, and the
sorrel was more resistant. According to the results, sunflower extract as a strong
combination for weed control can have promising results for sustainable agriculture.
In order to have data on the consumption of okra in Ivory Coast, a survey was
carried out in a school in the town of Adjamé among young people aged between 15
and 35 years. The survey showed that all respondents knew okra 57.80% of
respondents appreciate okra fresh, 39.20% dry and 03% do not appreciate at all the
okra. It also showed that 18.60% of respondents appreciate the sauce gombo, 20.80%
gouagouassou the sauce, the 13.80% Kopé sauce, 39.20% djoumblé the sauce, sauces
made 0.8% made from sheets of okra. 06.80% do not like these sauces. All people
surveyed know the varieties of "Gombo baoule" and "Gombo dioula." In conclusion,
the existing prejudices about fresh okra are the dried okra is more popular among
young people in Côte d'Ivoire.
Five diets (diets incorporated with folic acid, vitamin B, vitamin C, vitamin/
mineral mix and control) were used to determine their effects on survival, digestive
enzyme activity, protein profiling and growth of striped snakehead Channa striatus
fingerlings. All vitamin diets showed significant difference in enzyme activity like
protease, amylase and lipase, when compared to that of control. The fingerlings fed
with vitamin C diet showed significantly (P<0.05) better performance in terms of
survival rate, weight gain and Specific Growth Rate (SGR) when compared to the rest
of the four diets. The electrophoretic studies revealed that high molecular weight
fractions were added up in muscle tissue of C. striatus fed with vitamin and mineral
supplemented diets.
Mining is considered as a difficult and harmful job as it is done in a very
difficult physical and environmental condition. In addition to that, miners are exposed
to the dangers, damages and even death because of the bad condition of mines. The
dangers of mines are different in accordance with the kind of mine which may be
underground or surfaces. The dangers may be a bit different in different cities and
mines. Main harmful factors in mining are the physical damages, hyperthermia,
hearing loss, lung diseases, musculoskeletal diseases and facing with dangerous gases
and beams. The purpose of this essay is to examine the effect of physical, chemical
and biological harmful factor on miners. This survey has adopted descriptive method
and data are collected by library method. The results showed that the exposure of
chemical factors such as dust, methane and silica, and physical factors such as noise,
radiation, and biological factors may have great danger for miners.
The intensive study was conuducted for the prevalence and distribution of
Armigeres obturbans for the first time in the rural area surrounding Rajkot City. Seven
villages were identified for the study species identification, larval density, adult
density and distribution of breeding sites of the species. Results showed that adult
density of Ar. obturbans during monsoon was highest and post monsoon period was
most favourable for the species. Also the breeding sites of the species were recorded
more during this period. While during winter season majority of temporary breeding
sites dries out because of temperature decrease. Therefore, the temperature and
rainfall are the two variables that showed major effect on the breeding activities of
this species.
In order to assess the Myxosporeans fauna of Cameroon fresh water fishes so
as to find the fight strategies, 655 specimens (350 Oreochromis niloticus and 305
Barbus callipterus) were sampled in Mapé river (Sanaga basin) and examined.
Standard methods were used for the sampling of fishes, conservation and microscopy.
Morphometric characteristics of the spores were used for species identification. Two
new species belonging to the genus Myxobolus Büstchli, 1882 were described namely
Myxobolus tchoumbouei n. sp in Barbus callipterus which formed cysts within various
organs (fins, skin and operculum); Myxobolus mapei n. sp parasite of kidneys and liver
in Oreochromis niloticus and Barbus callipterus. Myxobolus tchoumbouei exhibited
very long spores (19.19 x 8.89 μm), pear-shaped with rounded anterior end
sometimes flattened. Polar capsules were dissymmetrical. They measured 7.60 x 3.00
μm for the bigger and 7.06 x 2.62 μm for the smaller. Myxobolus mapei n. sp had
ellipsoidal spores (13.50 x 6.83 μm) with unequal polar capsules. The larger polar
capsule (6.44 X 2.88 μm) was about 1.5 times longer than the smaller one (4.13 X 1.61
μm) and filled half of the spiral cavity. The awareness about these parasites is useful
to find fighting strategies.
Hyaluronic acid (HA) is also known by the name hyaluronan. The necessity for
using this fabulous material lead to investigate non-pathogenic strains which produce
this material. The most non-pathogenic strain is S. thermophilus. The lack of literature
on microbial production of this substance by the strain prompted us to examine the
microbial production of HA from it and also to examine optimization of culture
conditions where HA is produced. The bacteria Streptococcus salivarius sub.
thermophilus was obtained from the Bank of Scientific and Industrial Research of Iran
(PTCC 1738). To separate S. thermophilus strains from yogurts, three types of yogurts
were used. They were cultured by pour-plate and surface methods on STA medium. To
identify the isolated strains, biochemical tests and Polymerase Chain Reaction (PCR)
were used. Bacterial strains isolated from yoghurts were identified as S. thermophilus
MN-BM-A02, S. thermophilus JIM8232 and S. thermophilus MN-ZLW-002. To separate
the capsule strains, each strain was cultured on STB medium and then they were
centrifuged. In order to purify the samples, ethanol and charcoal were used. To
optimize production, variety of sources of carbon, nitrogen, temperature and pH were
studied.
The qualitative and quantitative dynamics of the copepod community in
Hendijan harbor was studied through zooplankton samples collected seasonally in
summer 2010 (July- August), autumn 2010 (October), winter 2011 (December-
February) and spring 2011(April). The copepods community was represented by 27
species, belonging to calanoida (16 species), cyclopoida (5 species), Poecilostomatoida
(3 species) and harpacticoida (3 species). The highest abundance of copepods was in
summer (14402±3352 Ind/m3) while the lowest was in winter (852±155 ind/m3). Of
the adult forms, Acartiella faoensis was the most abundant species, forming 19% of
the total copepods, followed by Paracalanus parvus (17%), Corycaeus andrewsi (13%)
and Clausocalanus arcuicornis (8%). Most of copepod species displayed distinct
seasonal occurrence relative to environmental conditions. The spearman’s correlation
revealed that temperature and salinity were the most important factor controlling the
size of copepods density in Hendijan harbor. The cluster analysis demonstrated
different types of association between copepods species. The highest value of
Shannon’s diversity index, Margalef index and Pielou’s evenness was noticed in
summer. These results revealed that the summer is different from other seasons of
the year and in this season the ecological situation is better and more stable than
other seasons in Hendijan shores waters.
The main purpose of this research was to investigate the women pregnancy healthy status and behaviors in Eastern-Azerbaijan province referred to the treatment health centers in 2012. The present study was a cross-section study. So 30
married women between 15-49 years old have been taken up randomly for family adjustment and mother health and pregnancy care. A questionnaire including the demographic features and other questions about the status and behavior of the
pregnancy health affairs were used to collect the results. The obtained data of these questionnaires were analyzed by SPSS software. The results that showed 63.8% had itching or the vaginal stimuli and 34.9% (52 ones) had bad-smelling secretions and
36.9% (55 ones) had intense pain around the abdominal area. The investigation of these infectious diseases through sexual path showed that about 0.5% (3 ones) are challenging with these mentioned disorders. The results of the barrenness showed that about 8.7% (52 ones) tried to get pregnant but they did not get pregnant.
To evaluate the effect of humic acid fertilizer on potato tubers in 2010, trials were conducted in the Province of Iran. The experiment was conducted on a split plot with randomized complete block design having three replications. Main plots consisted of four levels of humic acid (0, 1, 2, 3 times) solution in water irrigation and sub-factor consisted of three varieties of potato (Marfona, Satina, and Born). During planting the application of humic acid at the rate of nine liters per hectare per load at the beginning and start of creating tuber formation respectively were done. Analysis of variance showed that the smallest and largest tuber weight, number of tubers per plant and yield per plant were not significant. Effect of humic acid on the smallest mean tumor weight at 1% and the number of tubers and yield per plant showed significant difference at 5% level. The largest tuber weight was also not significantly different. Interaction of humic acid fertilizer in any of the measured parameters showed no significant difference in potatoes. Comparison by Duncan test showed that the application of humic acid in all the three stages of growth had shown great impact on tuber weight. The highest number of tubers per plant has been associated with the use of humic acid (27 l/ha). The number of tubers per hectare with the application of 18 litres of humic acid showed no significant difference. The amount of humic acid applied were 18 and 27 litres per hectare, and increased performance is in the range of 13 and 29% respectively.

SPSS-15 software and the application of the inferential and descriptive statistical tests (K2 and T-tests) were also applied in order to analyze the related data in this study. The significance level was considered as p<0.05.
More than half of these related research units of both groups had experience (61.5%) and control (55.8%) regarding all women in this study; the mean score of the low weight infants on the first month had not shown any statistical significant difference; but on the second months (p=0.04) and the third months (p=0.001), they had shown statistical significant difference progressively. The healthcare based on home-visit had influence on the recovery indices of the low weight infants. Hence, nurses and other health monitors of the infants should apply for the healthcare programs based on home-visit particularly in caring infants.
Protein was extracted from muscles of Channa striatus and attempts were
made to evaluate in vitro antibacterial activity against clinical bacterial isolates. The
higher concentration of protein (100μg/ml) extracts exhibited a pronounced activity
against Pseudomonas aeruginosa (21 mm), Proteus vulgaris (19 mm), Citrobacter sp
(19 mm), Klebsiella pneumoniae (18 mm), Micrococcus sp (17 mm), Bacillus subtilis (16
mm), Staphylococcus aureus (15 mm), E. coli (14 mm) and Serratia marcescens (5
mm). The minimum inhibitory concentration and minimum bactericidal concentration
were found to be 20-40 μg/ml and 80-100 μg/ml respectively for the extracts of
Channa striatus protein against test organisms. This study confirms that C. striatus fish
protein extracts possess antibacterial activity against a wide range of microbes and
justified that it could be used in the traditional medicine as a remedy for the
treatment of bacterial diseases.
Food security in a growing population with limited natural resources is one of
the most important issues of the world. Accumulation of heavy metals in food and
their concentrations increase and reaching to a risk limit can threaten human health.
The purpose of this study, is to study the heavy metals lead and cadmium in
vegetables, cultured on spinach and watercress at 10 Gardens of Ardabil. This study is
cross-sectional and 81 samples in water, soil, and spinach and watercress were
prepared during the months of June, July and August in 2015 and after preparation
according to the standard methods and using atomic absorption spectrophotometer
(Perkin Elmer) for the determination of heavy metals. SPSS software was used for data
analysis. The results showed that the mean level of lead and cadmium in all samples
were less than the EPA standard. Between studied orchards in terms of the amount of
cadmium and lead no statistically significant different was seen. The independent ttest
showed that in terms of cadmium between two species of spinach and watercress
there found a significant difference at the 5% level so that the amount of cadmium in
spinach was more than the watercress. Since the concentration of heavy metals in all
samples at second and third stages in July and August were zero, but in the first step
in June, the amount of heavy metals have been found in some samples showed that
all three samples of first cut had more contamination than second and third cut. And
in this case, the concentration of heavy metal pollution in hibernation at vegetable
gardens Ardabil is possible. The results of spinach cadmium amount in the first cut in
the three garden of viz.,3, 6 and 10 showed that in the garden (3), the amount of
cadmium in water is higher than the standard and is concentrated in spinach and the
gardens of 6 and 10 Cadmium in the soil of the gardens, is slightly higher that is
condensed in spinach thus it can be considered that spinach in terms of cadmium has
bioaccumulation.
Generally, the reconstitution of palaeo-geography and related environments
is based on the study of sediment markers such as grain size and clay mineralogy. In
this research, 90 surface and subsurface sediment samples from eight cores were
analyzed for grain size and clay mineralogy in southern part of Urmia lake coast and
adjacent areas. Abundant minerals are quartz, feldspars, calcite and dolomite. Heavy
minerals identified were epidote, hornblende and zircon. Clay minerals are Kaolinite
and Smectite mainly. Clay mineralogy and mean grain size of sediments in eight cores
of Urmia Lake; reflect climatic conditions in this region. Relatively coarse sediments
usually deposited during Urmia Lake low stands and relatively fine sediments
deposited during high stands. The mineralogy of the clay-size fraction was determined
by X-ray diffraction (XRD). Mineral assemblages display two climate conditions: Those
having large Kaolinite, quartz, and feldspar peaks but a small smectite peak
(interpreted to be cold times), and those with small Kaolinite, quartz and feldspar
peaks and a large smectite peak-(warm sediments). In addition, smectite content
correlate well with high mean grain size in Urmia Lake sediments, whereas sediments
rich in Kaolinite, quartz, and feldspar correlate well with finer mean grain size.
Chemical elements of the total sample are mainly of terrigenous origin, supplied by
“Discharge Rivers”, which discharges in Urmia Lake. Variations in clay mineralogy and
grain size didn’t indicate that the lake-level variations and nature of sediments
delivered to the lake vary in concert with global climate changes, recently. Human
activities such as Dams’ constructions and agriculture have probably induced
variations in the mobilization of chemical elements.
According to the Convention on the Law of the Sea 1982, constructing
artificial island is permitted and countries can construct artificial islands in their own
territory. Constructing artificial islands in the Persian Gulf area makes the countries in
the region, especially Iran, to pursue the issue with more sensitivity. According to data
dissemination principle of International Environmental Law, the countries that
construct artificial islands should notify other states regarding construction and
properties of their own artificial islands. Today, artificial island construction is being
increased and this has caused many environmental crises including increase of water
darkness and pollution and transport of coastal sediments. In this study, the
destructive results of constructing artificial islands in the Persian Gulf environment,
the effect of development of new land space from geopolitical view, and also
constructing artificial islands from the viewpoint of International Law of the seas have
been reviewed. Moreover, according to the fact that the notion of governance in
modern International Law have been modified regarding the use of environment and
sustainable development, the states will have limited right to construct artificial
islands.
The use of biotechnology in the propagation of plantain and
banana (Musa sp.) of great importance to induce, tolerant to plant genotypes for
diseases and high yield potentials. However, auxins and cytokinins should be used,
which are expensive and can sometimes cause changes in the regenerants obtained.
Both traditional growth regulators (auxins and cytokinins) and non-traditional growth
regulators (brassinosteroid analogues and mixtures oligogalacturonide) are used in
the in vitro propagation of crops, but mush progress has been hindering due to the
sufficient knowledge and impact of different phases prevailing in the
micropropagation of banana hybrid 'FHIA-18' (AAAB) is present hitherto. This work
was performed in order to evaluate the biological activity of an analogue of
brassinosteroids (Biobras-6) *ABr+ and a mixture of oligogalacturonide with the degree
of polymerization between 9 and 16 (Pectimorf) *mOLG+. The effect of ABr and mOLG
are determined as a substitute or complement of auxin (IBA or IAA) and cytokinin (6-
BAP) for the establishment of in vitro multiplication and rooting of plantlets and in the
acclimatization phase. Non-traditional regulators phenolization decrease the explant
growth in the establishment phase of in vitro propagation; but increased the number
of shoots per explants (above 3.5) and improved survival of vitro plant during the
acclimatization phase.

uses and use pattern, life form; plant part used and accession number of the
medicinal flora together. The paper describes distribution and local/traditional uses of
the 256 medicinal plants representing 96 families, in which pteridophytes were 1%,
trees were 18%, shrubs were 25%, herbs were 52%). Various plant parts used in
formulations, such as: underground part- 33%, leaves- 24%, whole plant- 11%, bark-
7%, seeds- 7%, resin /latex/oil- 4%, stem/ shoot/ wood- 4%, flowers and
inflorescences- 5%, fruits and nuts- 5% were used in different ailments.
There is a great contamination of water, soil, air, soil erosion, pest resistance
and extensive use of chemical fertilizers cause a turn to induce agriculture for
producing safe and clean products. For this purpose, by using natural materials like
algae on the beach, organic and environmentally friendly fertilizer was prepared. In
this investigation effect of Seaweed Liquid Fertilizer (SLF) of Ulva fasciata at
concentrations of 0%, 2.5%, 5%, 7.5% and 10% on some parameters of wheat
(Triticum aestivum var. chamran) has been investigated. Based on the results, above
algae can be used as a food supplement solution in the form of foliar spray at 2.5%
concentration with a significant increase in morphological and biochemical indices.
Cardiovascular diseases are considered as one of the threats to human
health, especially, in individuals with overweight. The aim of this study was to
investigate the effect of eight-week aerobic exercises in 10 to 12 years old overweight
girls. In this study, 27 overweight female student whit 10-12 years old were selected
and were randomly divided into two groups; a) training group (n=17) and b) control
group (n=10). Training group participated into the aerobic training for 8 weeks, with
70-85 percent of heart rate reserve maximum, 3 times a week and 60 minutes in each
session. The variables such as BF, BMI, WHR and VO2max, were measured in two
groups before and after the training period. The average of variables such as BF, BMI
and VO2max were significantly different between two groups (P<0.05). But the
average of WHR were not significantly different between two groups. According to
these results, aerobic exercise in 10-12 years old overweight girls, can have beneficial
effects on some cardiovascular risk factors.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

ABSTRACT:
Water is the primary need for all vital life processes. Water itself is an
environment, which support large number of organisms. However, it is highly affected
due to increased population, industrialization and unplanned urbanization that makes
pure water scanty to human beings. Day by day, water bodies are being highly
contaminated and are becoming biological deserts. At the same time, the quality of
standing water is becoming more and more unfit for humankind due to unwise use,
negligence and mismanagement. The quality of life is linked with the quality of
environment, hence biological components of fresh water depend solely on better
physico-chemical conditions, and therefore, analysis of physic-chemical parameters of
water is essential. The present study was conducted at two different stations in the
Rangawali Dam, from tribal area. Samples were collected between June 2007 and
May 2009 on a monthly basis and evaluated quantitatively. The study carried out for
two years included following physicochemical parameters of the water samples. The
regional climate at the site of study is distinctly marked in to three seasons, namely
Monsoon (June to September) winter (October to January) and summer (February to
May). The physico-chemical parameters like Rain Fall , Atmospheric temp, Water
temp, pH, Dissolved Oxygen, Dissolved carbon dioxide, Calcium, Magnesium Chlorides
and Sulphates were studied on seasonal basis, since the climatic changes seem to
influence the ecological factors, and physicochemical parameters.

2. INTRODUCTION
Freshwater biodiversity is the over-riding
conservation priority during the International Decade for
Action – ‘Water for Life’ – 2005 to 2015. Fresh water
makes up only 0.01% of the World's water and
approximately 0.8% of the Earth's surface, yet this tiny
fraction of global water supports at least 100000 species
out of approximately 1.8 million – almost 6% of all
described species. Inland waters and freshwater
biodiversity constitute a valuable natural resource, in
economic, cultural, aesthetic, scientific and educational
terms. Their conservation and management are critical to
the interests of all humans, nations and governments. Yet
this precious heritage is in crisis. Fresh waters are
experiencing declines in biodiversity far greater than
those in the most affected terrestrial ecosystems, and if
trends in human demands for water remain unaltered and
species losses continue at current rates, the opportunity
to conserve much of the remaining biodiversity in fresh
water will vanish before the ‘Water for Life’ decade ends
in 2015.
Water is the primary need for all vital life
processes. Ever since the prehistoric times, man has been
closely associated with water and the evidences of past
civilization that all historic human settlements were
around inland fresh water resources have proved it.
Water itself is an environment, which support large
number of organisms. However, is highly affected due to
increased population, industrialization and unplanned
urbanization that makes pure water scanty to human
beings. Day by day, water bodies are being highly
contaminated and are becoming biological deserts. At the
same time, the quality of standing water is becoming
more and unfit for humankind due to unwise use,
negligence and mismanagement. Therefore, quality
assessment of water is the most urgent need of the hour.
It can be done either by monitoring the physico-chemical
properties of water or by analyzing inhabiting biota.
Since the problem of water pollution in India is very
critical extensive studies are required to protect the
natural and manmade water sources.
The problem of pollution of water resources, due
to the discharge of domestic and industrial wastes and is
a great threat on the international scale. And for this,
economical methods to assess water pollution are
needed. Any impairment caused by pollution has its
effect on the aquatic biota. Therefore, a continuous effect
on the aquatic biota reflects the conditions existing in the
aquatic environment and the data can be utilized for the
monitoring of water pollution.
MATERIALS AND METHODS
Sampling method analysis:
The present study was carried out to study
physico-chemical parameters of Rangawali dam,
Navapur, Dist-Nandurbar. In two years of study period
2007-08 and 2008-09 data of rainfall was collected from
the collector office District Nandurbar. Atmospheric
temperature was recorded with the help of mercury
thermometer. The water temperature, Dissolved Oxygen,
pH, salinity, and dissolved carbon dioxide were recorded
by using portable water analysis kit.
These above-mentioned parameters were
analyzed on the spot at selected stations one and one,
soon after collecting the samples at fixed date and during
6 A.M. to 8 A.M. The estimation of total calcium,
magnesium, sulphates and chlorides were analyzed in the
laboratory after immediately colleting samples. These
parameters were measured in the laboratory by applying
respective methods (APHA, 1998). For the analysis of
physico-chemical factors, the surface water was collected
from the fix spots of Rangavali Dam, every month
between 6 A.M. to 8 A.M. on fixed date to avoid the
fluctuation in the observations. The work was carried out
for the period of two year 2007-08 and 2008-09.

DISCUSSION
The present study on Rangavali Dam from
Nandurbar District, Maharashtra State, India, was carried
out to find out their physico-chemical characteristics
monthly variations of physico-chemical characteristic
such as rainfall, temperature and the other factors such as
pH, dissolved oxygen, free carbon dioxide and some
salts play an important role in the biology of the
organisms and in aquatic environment. A sound
knowledge of the factors help in understanding the
complex processes of interaction between the climate
and biological processes in water bodies. It is important
to understand the water quality, fauna their dynamics and
functioning of these ecosystems as well as the impact of
increasing human activities on them for management of
fresh waters and keep them in healthy state to changing
environment sustain the future region. The quality of life
is linked with the quality of environment, hence
biological components of fresh water depend solely on
better physico-chemical conditions, and therefore,
analysis of physico-chemical parameters of water is
essential. .
pH is an important factor, which controls the
chemical changes, species composition and the metabolic
activities of living organisms inhabiting the water body
The present result are similar and in agreement with
those obtained in the investigation of ( Hutchinson 1957,
Subba Rao and Govind 1964; and Avasti and Tiwari,
2004). The higher values of pH in summer may be due to
the utilization of bicarbonates and carbonates buffer
systems/ According to Saran and Adoni (1984) during
photosynthesis free carbon dioxide and bicarbonates are
utilized and there is release of carbonates which increase
the quantity of dissolved oxygen and pH. Pearsall
( 1930) and Zafar (1966) ; observed that pH of the water
appeared to be depended upon the relative quantity of
calcium, carbonates and bicarbonates. The water is
tended to be more alkaline when it possesses larger
quantities of these ions (Zafar, 1966): “The pH level was
not uniform during the study period, of 2007-08. In the
summer months, pH value was low while it was inclined
from spring to pre-monsoon towards alkaline pH.
According to Das (1961), the decrease in pH during
summer is due to decrease in water level, which
increases the concentration of free carbon dioxide,
released through by respiration of aquatic organisms,
thus lower the pH.
Seasonal variations in Dissolved oxygen content
revealed maximum value during monsoon and minimum
during summer for both years. The above observations
were agreed with the finding of Singh and Raj (1999)
and Md. Ilyas (2002). The lower values of DO in
summer were probably due to high temperature
evaporation and increased rate of decomposition of
organic matter in water. The other reasons may be
attributed to the biological processes such as oxygen is

6. moderately soluble in water and solubility decreases with
increase in temperature, increase in the various
pollutants. The solubility of oxygen in pure water at 0 0
C
is 14.6 mg/1. Whereas water usually contains about 8.0
mg/1 of DO at room temperature. Muragawel and
Pandian (2002 ) reported the existence of positive co-
relation between DO and water transparency, pH,
phosphates and nitrates.
The low value of the DCO2 occurred mainly due
to higher rate of utilization of carbon dioxide in
photosynthesis while the higher carbon dioxide value
may be resulted due to higher decomposition of organic
matter (Mishra and Saksena 1991; Dwivedi and Sonar
2004). Another reason for the fluctuations in the DCO2
level in the water may be, due to formation of carbonic
acid in water which dissociates into H+
and HCO3
-
ions
which brings a change in the pH of water as hydrogen
ions are set free and HCO3
-
react with calcium to from
calcium carbonate insoluble in water. This phenomenon
explains that how concentration of carbon dioxide in
water limits pH and concentrations of HCO3
-,
CO3
-
, and
CO2 (Ruttnerr, 1953).
Calcium is essential for all organisms, being an
important cell wall constituent and regulates various
physiological functions in animal too. The calcium
content was found to increase during the summer and
decrease during the winter. Calcium is considered to be
more important because it is an integral part of
organismic tissues. It increases the availability of other
ions. High calcium content in the sediment of the water
bodies support the growth of mollusc. It is also required
as a nutrient for various metabolic processes, and assists
in proper translocation of carbohydrates and facilitates
other ions(Wetzel 1975). Calcium plays an important
role in various ways in the growth and population
dynamics of freshwater and its fauna. It is considered as
a basic inorganic element of algae and regarded as an
essential nutrient for various metabolic processes
(Ruttner, 1953). The calcium observed during the present
study was in agreement with that of calcium in
freshwater bodies suggested by Kaul et.al.(1980).
Magnesium is required universally by chlorophylls
bearing plants as it is the Mg-porphyrin component of
the chlorophyll molecule and bearing a co-factor for
various intracellular enzymatic transformations (Wetzel,
1975), Magnesium, calcium and bicarbonates together
cause alkalinity and in association with carbonates,
sulphates chloride and magnesium cause hardness in
water (Jain and Jain 1988). In the present study
magnesium level was highest during winter and lowest
during summer while Saran and Adoni(1984) reported
maximum magnesium hardness during both the summer
and winter seasons.
Biological oxidation of reduced sulphur species
to sulphates also increases its concentration. Rainwater
has quite higher concentration of sulphate particularly in
the areas with high atmospheric pollution. Discharge of
agricultural runoff and domestic sewage in waters
increase its concentration. Most of the salts of the
sulphates are soluble in water as such, it is not
precipitated. However, it may undergo transformation to
sulphur and hydrogen sulphide depending upon the redox
potential of the water, (Trivedy and Goel 1984). In the
present study, sulphate level varied between 0.02 mg/1.
The lowest level was noticed in winter where as in
monsoon it was highest. The sulphates range was not so
wide season Azwise as well month wise during the two
years of study. The low concentration of sulphate in
winter appears due to presence of higher phytoplankton
population and domestic sewage. The present findings
are, thus, in accordance with Sneha (1986) . High
concentration of sulphate during monsoon might be due
to surface runoff which brings more suspended soils
along with organic and soluble salts ( Sneha, 1986; and
Singh, 2000).
A quality parameter of significance is the chloride
concentrations. Chloride concentration in natural water
results from the leaching of chloride from rocks and soils
Shejule and Ahirrao 2015

7. with which water come in contact. Agricultural,
industrial and domestic waste waters discharged to
surface water are also source of chloride in the aquatic
system. Chlorine in Free State, which is used as
disinfectant, may be converted into chlorides or
combined with organic matter to form toxic compounds
(Adoni, 1985). Permissible limit of chloride level in
portable water is 200 mg/l (WHO 1972) however, level
up to 1000mg/l is safe for human consumption (IS
10500, 1983). Results of the present investigation
revealed that the chloride in water bodies is within the
permissible level and is suitable for portability. In the
present study lower values of chlorides were observed,
22.2 mg/l to 44.7 mg/l. The above finding are in
agreement with Ganpati (1960); Zafar(1964); Prakash
(1994); and Awasthi and Tiwari(2004).
