Investigation of traditional veterinary phytomedicines used in deosai plateau...Shujaul Mulk Khan
In the present investigation, the traditional ethno veterinary knowledge is totally in the custody of elder members of the community. The young ones are unaware about such important practices. Previously no ethno veterinary study has been carried out from this study area. Therefore, present study has been designed to record the ethno botanical uses of indigenous plants Deosai Plateau, Pakistan. Total 59 people of different ages (38 Males and 21 females) were interviewed and information was collected through semi-structured questionnaires. The data obtained were quantitatively analyzed using Use Value (UVi) formula and Relative Citations Frequency (RFC ). The collected specimens were pressed, dried, preserved, mounted on Herbarium sheets and after confirmed identification were submitted in the Herbarium, Department of Botany, Hazara University, Mansehra, Pakistan. The present findings revealed that thirteen medicinal plant species were recorded for their ethno veterinary uses. Belonging to nine families out of which 92% are herbs and 8% shrubs. Polygonaceae is the dominant family used in the treatment of different disease (23.07%) followed by lamiaceae and apiaceae. Majority of species were used in treatment of digestive disorder (9.4%), followed by diarrhea (7.5%), abdominal and dysentery (5.6%). Leaves and roots are the most frequently used parts in the treatment of various diseases (29%) each, followed by flower (18%). Medicinal plants most with used values were Aconitum heterophyllum Wall. ex Royle (0.84), Rheum webbianum Royle (0.80) and Berberis orthobotrys Bien. ex Aitch.

The present study is on floristic investigation and soil analysis of Thirtharampura reserve forest, Tumkur district, Karnataka, India. It is the dry deciduous type of forest contains a rich diversity of angiosperms, here we found a total of 126 taxa of 99 genera under the 41 families from this forest. Fabaceae 15 genera and 24 species was the dominant family followed by the Rubiaceae 8 genera, 9 species , Asteraceae 7 genera, 7 species , Rutaceae 5 genera, 5 species , Malvaceae 4 genera, 5 species and Moraceae 2 genera, 6 species with the medicinal, timber yielding, ornamental and wild edible plant species. The forest is majorly covered by tree species with 60 come after shrubs 21 , herbs 10 , and climbers 9 . Some important medicinal plant species like Erythroxylummonogynum, Hemidesmus indicus, Rhinacanthusnasutus, Azadirachta indica, croton bonplandianus, Diosporusmontana, Echinopsechinatus, Emblica Officinalis, were often these medicinal plants used for the treatment of pain, wounds, cuts, and fractures, etc. by the native peoples. The forest soil contains low content of nitrogen along with sulphur and copper but it has high content of Iron and Manganese nutrients. The forest was disturbed by firing, mining activities, and human activities. Only the tree species were withstanding against the firing activity, herbaceous species were lost along with new sprouting species due to firing activity in the forest. The Fabaceae species were more survive in this forest, because of nitrogen fixing capacity in their root system. Yatheesharadhya B | Meena H. R | Sushma G. C | Poornima M. C | Shashank A.

Assessment of Endophytic Fungal Flora Responsible for Plant Growth Promotion...Sryahwa Publications
The present paper discusses the highest colonization of fungal endophytes as Alternaria speciesin comparison with Colletotrichumspecies and Fusarium species in all three plants Pongamia pinnata, Securinega leucopyrus and Rhus mysorensis. These endophytic fungi protect these plants from various
environmental factors such as temperature, moisture and other environmental factors.
It has been observed that anthropogenic activities namely, farming, tree harvesting, seasonal fire regimes, introduction of exotic tree species like Eucalyptus and Greviella, and collection of herbs for medicinal use are going on and form a major threat for the orchid Polystachya fusiformis (Thou.) Lindl. This study determined the relative abundance and distribution of the species Polystachya fusiformis (Thou.) Lindl. in the Manga range ecosystem of Kisii, Western Kenya during two flowering seasons. Other results of the present study were analyzed with SPSS version 17 for paired sample correlations, OriginPro7 t-Test and ANOVA, Minitab 16 chi-square test. From the analysis there is a significant correlation between altitude and number of orchid population clusters with a p-value of 0.008 in the distribution of Polystachya fusiformis (Thou.) Lindl. which led to rejection of the null hypothesis. The Levene’s test for equal variance shows that at α 0.05 there is a significant difference between altitude and number of clusters as indicated by the P value of 0.00004. Of the 88 sites sampled, only 41sites had orchid clusters. Principal component analysis using Unscrambler 9.7 indicated that many of the orchid population clusters fell within the range of one or two orchid population clusters. The score plots from the two Hoteling’s outputs show how well data is distributed including sample patterns, groupings, similarities and differences during the study. The two analyses illustrated how fire affects the orchid population on fire prone sites of the range. Orchid population clusters progressively increased with increase with altitude range (from 1800m to 1850m) above sea level, but number of orchid population clusters decreased towards 1950m. Sites with minimal anthropogenic disturbances (1796m, 1830m, 1854m, 1886m, and 1890m) had a higher number of orchid population clusters.

About 63 species belonging to 29 genera of pteridophytes have till date have been reported from Rajasthan dating from kings Sketch of flora of Rajputana 1878 79 . But an exhaustive survey of all pteridophytic localities during different seasons of the year during the past decade 1975 85 has revealed the occurrence of many species belonging different genera. Thus, Athyrium hohenockerianum, Asplenium lanulatum, Cheilanthes belangeri, Botrychium lanuginosum, Dryopteris parasitica, Pityrogramma calomelanos, Pteris cretica and Athyrium parasnathense are seen. This may be regarded as a clear indication that these taxa have recently been lost eradicated from Rajasthan due to one factor or the other. It has also been regularly observed that the population densities of many of the present day. Rajasthan pteridophytes have been decreasing at an alarming rate specially in respect to such restricted taxa as Asplenium pumilum var. hymenophylloides, Selaginella rajasthanensis, Isoetes reticulata, I. rajasthanensis and Marsilea aegyptiaca. Similarly, populations of some ferns growing at Mt. Abu like Ophioglossum gramineum, Araiostegia pseudocystopteris, Pteris vittata, Dryopteris cochleata and Nephrolepis cordifolia are also becoming thin and localised and reported as seriously rare taxa of Mt. Abu. Seriousness and severity of the threat to pteridophytic flora of this region is emphasized specially because of the scantier floristic resources of the state. Adiantum recurvatum D.Don Fras. -Jenk is a new record to the pteridophytic flora of Rajasthan.

DIVERSITY STUDY OF ODONATA IN CHINTAMANI KAR BIRD SANCTUARY, KOLKATA, WEST BE...IAEME Publication
Species records of protected areas by creating checklists and updating them is crucial to understand species distribution, dynamics and possible threats to them. Chintamani Kar Bird Sanctuary is a protected area famed for its wide variety of floral and faunal diversity, located in close proximity to the metropolis of Kolkata and odonata is real flagship taxa of freshwater ecosystems, often used as indicator species to assess the quality of their close environment. Adult odonata (both suborder- Anisoptera; Dragonfly & Zygoptera; Damselfly) needs resource-rich terrestrial habitats for maturation, feeding, resting, and mating. Species diversity indices like Simpson and Shannon are applied to analyze the odonatan population diversity in this protected area. Our study of odonata populations has been made for the first time in this protected area. As far as species richness is concerned, the family Libellulidae is found to be dominant among Anisoptera whereas species of the family Coenagrionidae is dominant among Zygoptera. Our observations support the importance of this region in providing valuable habitats for Odonata.
Aquatic weeds diversity of Fatki River in Magura district, BangladeshAbdullaAlAsif1
The study was conducted at Fatki River under Magura district to learn the aquatic weeds diversity and abundance. This paper focused on species variation, number of species, water quality parameter and identification of aquatic weeds. It was assessed by collecting samples from Chukinogor Ghat, Kechuadubi and Arpara bazar during May to August, 2016. Aquatic weeds were abundant in rainy season and the semi-aquatic weeds were available almost all the year round. According to this study, total 22 species belonging to 12 orders, 16 families and 21 genuses were found. Again, 46%, 28%, 26% of total aquatic weeds percentages identified from the Chukinogor Ghat, Kechuadubi and Arpara bazar respectively. During this study period, nine species of family Pontederiaceae, Convolvulaceae, Menyanthaceae, Asteraceae, Poaceae, Araceae, Amaranthaceae, Polygonaceae were common in Chukinogor Ghat, Kechuadubi and Arpara bazar. Noticeable species-Lemna minor, Marsilea quadrifolia, Ludwigia palustris, Aeschynomene aspera, Najas graminea, Hydrilla verticillata, Najas guadalupensis, Utricularia inflate were only found in Chukinogor Ghat. This species are easily adapted in large areas. On the other hands, two species were common in Chukinogor Ghat, Kechuadubi-Pistia stratiotes and Equisetum hyemale. Prominent species of Arpara bazar were Cyperus rotundus and Xanthium indicum. Total 11 species of aquatic weeds were mainly recognized from these Kechuadubi, while greatest number was recorded of 20 species from Chukinogor Ghat and 12 species were have its place to Arpara bazar. Management technique and water quality parameters were also studied during study period and the temperature was recorded 29.0-30.00 ºC in Chukinogor Ghat, same as 28.0-320 ºC in Kechuadubi. Furthermore, 29.0-31.00 ºC temperature was found in Arpara bazar. DO levels were stable at ranged from7.0-7.5 ppm in Chukinogor Ghat and 4.7-5.3 ppm was recorded in two experimental Kechuadubi 4.5-5.0 in Arpara bazar respectively. This difference may arise due to the using of aerator in the Chukinogor Ghat same as decomposition, intensity of light in Kechuadubi and Arpara bazar. Transparency was 28-32cm in Chukinogor Ghat, 36-44cm in Kechuadubi, and 38-42 cm in Arpara bazar.

First floristic exploration of the distric torghar khyber pakhtunkhwa pakistanShujaul Mulk Khan
District Tor Ghar lies on the western most edge of the Himalayas Range of Mountains. Plant scientists have explored most parts of Pakistan but still certain regions including Tor Ghar are un-explored. Thus it is imperative to introduce region in floristic terms for the first time. The study was initiated to not only provide first inventory of vascular plants but also to evaluate floristic diversity of the region. The research area was extensively visited during flowering and fruiting seasons of plants during the summers of 2012 and 2013. Plants were collected from various localities, voucher numbers were given to specimens and other relevant data pertaining to locality i.e., habitat, habit, family, scientific and local names were recorded for each species. Mounted copy of each voucher specimens were deposited to the Herbarium of Hazara University Mansehra. Results of this study were arranged according to Benthum & Hooker (1862-1883) system of classification. This first exploration revealed a total of 331 vascular plant species belonging to 246 genera and 101 families. These include 12 species of Pteridophytes, 6 gymnosperms and 313 Angiosperms. The dicotyledons were represented by 79 families, 197 genera and 267 species, while monocotyledons by 14 families, 38 genera and 46 species. Families Asteraceae and Leguminosae were the richest families with 25 & 24 species followed by Poaceae (21 species), Lamiaceae (17 species) and Rosaceae (14 species). Families Ranunculaceae and Brasicaceae were represented by 10 species and Euphorbiaceae had 9 species. Moraceae, Apiaceae and Polygonaceae each had 8 species. Remaining families either included 7 or less than 7 species. It is believed that this very first check list of vascular plants of Tor Ghar District is a comprehensive picture of floristic diversity and will serve as a base line for future studies. This exploration is a part of an ongoing project in which we will explore plant communities and ecological as well as anthropogenic gradients of the regional flora in near future.
Observation for spoilage in fish and beef in a daily simulated local market s...IJEABJ
The degree of spoilage of fish and beef in a daily simulated market style of southwest, Nigeria was determined by Trimethylamine (TMA) levels in each sample using the standard pictrate technique. 100g of each of the three different parts of a bull (liver, meaty and fatty tissues) and fresh African cat fish (Clarias gariepinus) (liver, meaty portion and head) were purchased twice a week for five weeks from the abattoir and Oja-Oba market in Akure respectively. The samples were subjected to ambient temperature and their degree of spoilage was assessed after 3 hours, 6 hours and 9 hours of purchase. The results showed that, there was no significant difference (P≥ 0.05) in the effect of time (hours) on TMA concentration in different parts of the fish and bull samples, though, the mean concentration of TMA in the fish samples increased with time. However, the degree of spoilage is slower in the bull compared to the fish samples but higher in the late evening (9 hours). Hence, buying and selling of beef in the late evening should be discouraged to avoid consumption of unwholesome meat with high TMA concentrations, while fish should be stored-frozen and sold in deep freezers.
Eroding Fabrics of Communal Land Ownership in Papua New GuineaIJEABJ
This paper analyses the perceptions of 120 landowner-households of Nanadai Clan of Gaire Village in Central Province and Sek Clan of Madang Province concerning breaking apart of communal ownership of customary land in PNG. Previous researches have argued that there is lack of a clear distinction between individual and communal property rights in some parts of Papua New Guinea. The existing weak land administration system and mechanisms have contributed immensely towards tearing apart the bond and connections between clan members and the dismantling of communal land ownership in Papua New Guinea thus, compromising national land administration values and standards. Current practices reveal that customary land is held at the sub-clan, family and individual levels, while the major clans just bear ownership name-tag. The existing land legislation in Papua New Guinea recognises that ownership of customary land is vested in the clans, however, the realities on the ground from the findings of this research indicate otherwise. Therefore, this paper calls for the strengthening of the weak land administration functions and mechanisms together with the review of all existing laws to improve the standards of land administration system in the country. This paper argues that communal land ownership in Papua New Guinea is slowly breaking apart causing disharmony between
Agricultural Restructuring in Vietnamese Mekong Delta: Economic Analysis of R...IJEABJ
The study examined the economic analysis of sesame production compliant withagricultural restructuring plan in rural areas of Vietnamese Mekong Delta. Conditional non-probability sampling technique was employed to select 90 respondents who have produced sesame rotationally on rice field in summer-autumn crop season. Primary data were analyzed using both descriptive and inferential statistics including percentage, frequency and farm budget model. Gross Margin analysis was used to estimate cost, returns sesame production in the study area. The study revealed that the average cost, revenue, gross margins of production per hectare was 17.60, 37.38 and 20.56 million VND, respectively.Moreover,the average rate of returnsalsoindicated that with every 1,000 VND invested to sesame production, a farmer made a profit of 1,390 VND. As a result, it can be concluded that sesame farming is profitable in the context of agricultural restructuring strategy from rice to other crops in Mekong Delta region. It is recommended that smallholders should take initiative in participation in sesame cooperatives and ‘big field’ model to be more beneficial to inputs price, harvested machine and formal credit in the beginning of each season.
Seasonal Phenology of Reptiles in a Mediterranean Environment (“Castel di Gui...IJEABJ
The present work reports the seasonal phenology of the reptiles of the "Castel di Guido" Natural Park near Rome (Northern Latium, Italy). During field observations, between September 2014 and July 2016, transects were carried out along the ecotones of the park, in order to describe the period of seasonal activity of the reptiles present. The area is characterized by Mediterranean mesothermal climate. In the Mediterranean area, reptiles have a broader annual activity range than other European regions, greatly reducing winter latency. Reptile activities start very early, in some case it is possible to observe the snake Hierophis viridiflavus and lizards, such as Podarcis muralis and Podarcis siculus, in thermoregulation activity in the middle of winter. The mild climate that is recorded on average in autumn favors the activity in the period between September and December; Zamenis longissimus is observed regularly in October. Testudo hermanni mates regularly in autumn and it is active until the first decade of December. The research shows that during the winter period reptiles can be observed in activity; for some species, Chalcides chalcides, Podarcis sp., Hierophis viridiflavus, this seems to be a remarkable datum that broad considerably the annual phenology reported in the literature.
Evaluation of four plants compost teas against fungi responsible for Corn dam...IJEABJ
Corn (Zea mays L.) is one of the most important cereals in Côte d'Ivoire. However, Corn seeds and seedlings are susceptible to infection by a number of soilborne fungi which caused seeds decay before or after germination. The objective of this study is to evaluate the suppressive effect of Four plants compost teas (Chromolaena odorata, Ricinus communis, Nicotiana tabacum, Azadiracta indica) on Corn damping off. In vitro assays showed a most suppressive effect of C. odorata and R. communis compost teas on mycelial growth of pathogenic fungi. Results of in vivo trials showed significant reduction of Corn seedlings diseases incidence and high seed germination percent after treatment with C. odorata, R. communis and A. indica compost teas. No efficiency effect was noted with N. tabacum compost tea. This study demonstrated the usefulness of compost tea as an efficient biological tool for the control of fungi responsible of corn damping-off.
Microbiological Quality of Kunnu-Zaki Drinks Sold in Some selected Towns in O...IJEABJ
The microbiological quality of freshly processed and hawked kunnu-zaki drinks, a common Nigerian non-alcoholic beverage was investigated in some selected towns in Osun State, South Western Nigeria. A total of nine (9) towns were assessed. Kunnu-zaki drinks were purchased from these towns on twelve different occasions for a period of six month. The samples were microbiologically analyzed using standard methods. pH values ranged from 3.09 - 4.21 in East and West senatorial district. The TTA of the samples ranged from 0.32 - 0.49 in Central and East senatorial district. All the screened drink samples had varying levels of bacterial contamination ranging from 4.2 x 103 to 15.0 x 103 CFU/ml, 4.1 x 104 to 9.6 x 104 CFU/ml and 3.5 x 105 to 9.0 x 105 CFU/ml for total bacteria, coliform and E. coli count respectively. Total coliform count on MPN ranged from 3 MPN/ml to 93 MPN/ml. 77.78% of the total sampled drinks (n=108) that is (84/108) had bacteria and fungi count. While all the drinks sampled had total coliform count on MPN exceeding the recommended safe level of zero organisms detectable per 100ml. Seven (7) bacteria species were isolated from the kunnu-zaki drink sampled. The bacteria isolated were Escherichia coli, Bacillus species, Staphylococcus species, Pseudomonas species, Streptococcus specie, Enterobacter species, and Klebsiella species. Fungal count ranged from 3.3 x 106 to 8.0 x 106 CFU/ml respectively. Four (4) fungi were also isolated which include Aspergillus fumigatus, Penicilium italicum, Aspergillus niger and Aspergillus flavus. It can therefore be concluded that the presence of these isolated organisms in kunnu-zaki samples analyzed in Osun State could serve as indicator for the need to promote awareness about the possible health hazards that could arise due to the unhygienic ways of handling and processing of the beverage.

Effect of Aloe Vera wastes on physico-chemical properties and microbiological...IJEABJ
The aim of the present study was to explore the potential for using aloe vera wastes as amendment for soil to improve its fertility. Soil was exposed to four concentrations of aloin (rich in HAP) for 0, 7, 14 and 28 days. Physico-chemical parameters were analyzed: soil Ph, organic matter (OM), nitrogen, phosphorus, and cation exchange capacity (CEC). The activity of seven enzymes implicated in the C, N and S cycles were measured. Microbial Biomass was determined by the method of substrate induced respiration. BiologEcoplates (Biolog Inc., Hayward, CA) were used to estimate soil microbial functional diversity. Our findings suggested a decrease on phosphorus and nitrogen content and an increase on CEC after aloin addition. Also, a decrease on microbial biomass and enzymes activities was observed, except for FDA. Ecoplates results demonstrate a decrease on microbial activities depending on the incubation time. Moreover, our results indicated that bacterial communities of the tested soils have more affinity to consume substrates as Amino acids and polymers. Our results should be carefully considered in view of the agriculture waists reuse for a sustainable agriculture

Chitosan play an important role as an antifungal against Botrytis cinerea and the effect was a concentration dependent. The obtained results of in vitro experiment demonstrated that chitosan (4%) decreased radial growth of B. cinereato 2 %. Invivo the severity of infection reduced from 59.8 and 100.0 to 9.7, 33.8 and 40.1 in first, second and third week’s storage periods at 13C, respectively. Also, chitosan coating (4%) significantly caused an increase in fruit firmness whereas TSS was decreased with an increase by increasing in storage time. However,Vitamin C gave fluctuated results by increasing storage time. Gamma irradiation at 2.5 KGy reduced severity (%) of infected fruits from 55.5, 100 and 100 to 31.7, 45.9 and 49.9 and in healthy fruits severity (%) reduced from 48.9, 100 and 100 to 23.3, 25.1 and 29.1 in different storage periods 1, 2 and 3 weeks, respectively. Similarly, chitosan as well as gamma irradiation combination induced a significant increase of peroxidase enzyme (POD) activity. Induced changes in surface morphology and damage of cell structure caused by using chitosan shown by scanning electron microscopy. Also, gamma irradiation causes changes in hyphea structure and in surface morphology but combination of gamma irradiation with chitosan was more effective in altering fungus morphology and cell structure damage and no spore forming. This providing the efficiency of combination on reducing disease severity (%) of strawberry.
Biofumigation: A Potential Aspect for Suppression of Plant-Parasitic NematodesIJEABJ
Plant-parasitic nematode cause economic loss to crops throughout the world. Biofumigation is the environmental friendly control option for the suppression of plant-parasitic as well as other pathogenic soil microbes. Glucosinolates are the main active compound present in some plants which are responsible for biofumigation process. To increase the efficiency of biofumigation selection of varieties containing more glucosinolates is highly desirable. Plant growth stage, soil temperature, soil texture, moisture, soil depth and soil microbes play important role in efficient biofumigation.

In Egypt, research focusing on estrous synchronization in small ruminants based on Melengestrol acetate (MGA) supplementation, particularly in nulliparous ewes, is still lacking. The present work aimed to evaluate effect of long-term and short-term administration of melengestrol acetate (MGA) treatments on estrus synchronization and reproductive performance of nulliparous Barki Ewes. This study was performed in Siwa Oasis Research Station (Tegzerty Experimental Farm for animal production), belonged to Desert Research Center, Egypt. Forty five nulliparous Barki ewes with age ranging from 15.5 to 16.5 months, and 38 ± 0.23 kg average live body weight were assigned to one of three groups: (1) control (C, n = 15); (2) long-term treatment with MGA (n = 15, 0.22 mg/ewe/d for 14 days) and (3) short-term treatment with MGA (n = 15, 0.22 mg/ewe/d for 7 days). At the end of MGA treatment (14 or 7 d) all treated ewes were injected by 600 IU PMSG intramuscularly. The results showed that, ewes treated with MGA exhibited highest (P<0.05) estrus response rate (100%) in short term-MGA, followed by long term-MGA (93.33%), whereas the lowest was observed in control group (80%). Conception rates after natural mating were 85.71% and 93.33% for long term and short term MGA treated ewes, respectively. However, it recorded 100% in the control group. Fertility rate was significantly the highest (P<0.05) in short term-MGA (93.33%) than other groups (73.33%). There were no significant differences (p>0.05) in terms of lambing rate and prolificacy among the control and treated ewes. In the meantime, mean values of serum estradiol 17-β were lower (P≤0.01) in long-term treated ewes compared to those of short-term treated ones (27.20±1.78, 32.67±1.27pg/ml), respectively, while the lowest (P<0.05) level was recorded in the control ewes (13.01±1.31 pg/ml). Furthermore, overall mean values of serum progesterone in the control group (1.32 ± 0.09 ng/ml) was higher (P<0.05) than those of long- and short-term MGA treated groups (1.01 ± 0.13, 0.92 ± 0.11, ng/ml), respectively. It is concluded that reproductive efficiency of nulliparous Barki ewes could be improved by short-term supplementation with MGA.

Seriphidium herba-album (syn. Artemisia herba-alba) is a medicinal, aromatic, greenish-silver herb. It is used widely in folk medicine for treatment of diarrhea, abdominal cramps and in the healing of external wounds. It's also used for the treatment of diabetes mellitus, neurological disorders as epilepsy, Alzheimer’s disease, depression and jaundice. In this study we assessed the protocol for callus induction, maturation of somatic embryogenesis, frequency of germination and conversion into plantlets for leaf explants of Seriphidium herba-album using different concentrations of PGRs. Highest induction frequencies of embryogenic calli occurred after 35 days on MS medium supplemented with 1.5 mg L-1 2,4-D and 0.5 mg L-1 BAP. Optimum MS medium for higher frequency of matured somatic embryos was recorded using 5.0 mg L-1 BAP and 0.5 mg L-1 NAA and somatic embryos also induced young in vitro grown plantlets when cultured in the medium containing GA3 and kinetin. Hence, attempts to induce direct somatic embryogenesis have been achieved up to embryo regeneration and maturation.

The main plots were three poultry manure rates (0, 10, 20tons/ha-1) and sub plots, three spacing (50cm x 50cm, 100cm x 50cm and 100cm x 100cm). Data collected were plant height, number of leaf per plant, leaf area; number of fruits per plot, fruit weight per plot, fruit yield per hectare, fruit lycopene and vitamin C contents. Results showed plant height increased with reducing planting distance and increasing Poultry manure rate; 50cm by 50cm fertilized at 20tons/ha produced the tallest plants with most number of leaves but least leaf area LA. Number of fruits, fruit weight and yield per plot, per hectare increased with increasing planting density and increasing Poultry manure rates lycopene and vitamin c contents increased with Poultry manure levels within the different spacing. Spacing of 50cm by 50cm fertilized with poultry manure at 20 tons per hectare is recommended.
Antioxidant activity, photosynthetic rate, and Spectral mass in bean Plants (...IJEABJ
An increase in antioxidant activity is a common response in plants as a defense mechanism against biotic and abiotic stress factors, such response is also generated with the exogenous application of "defense activators", which have negative effects on plant metabolism. In this work, bean plants (Phaseolus vulgaris L.) cv. Pinto Nacional were treated with jasmonic acid (0.5 mM), salicylic acid (2 mM), Trichoderma asperellum (105 spores/ml), and Bacillus pumilus (105 CFU / mL), in order to determine the level of structural and metabolic response of the plants. On the seventh day after the application of the treatments, it was measured the enzymatic activity of catalase (CAT), peroxidase (POX), and superoxide dismutase (SOD). In addition, leaf impressions were taken to measure the stomatal opening and conductance, photosynthetic rate, and the mass spectrum (mass/charge, m/z). The antioxidant activity increased in plants treated with jasmonic acid and T. asperellum, which in turn significantly increased the stomatal opening and conductance, and photosynthetic rate. The mass profile showed that the plants treated with T. asperellum have a greater quantity of masses/charge, of which some had statistically highly significant difference according to the means test Tukey (p <0.05). It is concluded that some defense activators such as jasmonic acid and T. asperellum increase the antioxidant activity, defense response that concurs with the high photosynthetic and metabolic rate in bean plants.
Effect of Compost Extract Fortified with Tempe on Chili Mosaic Virus DiseaseIJEABJ
Mosaic disease caused by multiple infections of viruses in one of the most devastating virus diseases of chili pepper (Capsicum annuum) in Indonesia. Improving plant resistance by treatment with exogenous bioactive compounds is promisingly developed for plant protection in organic chili production. We demonstrated the suppressive effects of a fermented water extract of compost fortified with over-fermented tempe (TCE) on mosaic disease and its aphid vector. TCE was applied weekly by foliar spraying at 0.2 and 2.0 % on potted Capsicum growing in field. The result showed that treated plant sprayed with TNF preparation exhibited a significantly slower disease progression as represented by a lower area under disease progress curve compared to control plant. Disease suppression was obtained at concentration as low as 0.2%. TCE-treated plants were significantly less colonized by Aphis gossypii than control plant.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

I. INTRODUCTION
Sacred grooves are the conserved forest patches or
protected areas. The sacred groves in Kerala are tightly
bonded with religional backgrounds. The (Its) conservation
is mainly based on cultural, aesthetical and religional
aspects, In different areas this sacred places are devoted or
dedicated for different Gods i.e. serpentine Gods,
Nagadevatha, Nagayakshi .etc. Human activities are highly
prohibited in these areas. Touching plants ( and animals
associated with them ) in these sacred groves and gardens
was forbidden to all except the temple priest, and his too is
restricted to offerings to the Presiding temple Deity and
curing the ailments of local people (the temple priest was in
variably the village doctor). The study area includes one of
the famous sacred groove and serpentine temple,
Pathirakkunnathu mana. The present technocratic and
scientifically oriented society mistakenly considers that
religion is not interested in protecting and managing
biodiversity. The truth, however, is that religious values
very often help to protect biodiversity. The practice of
protection of patches of forests with temples in their vicinity
has long been in vogue in India and a few other parts of the
World. In some instances, forest patches or gardens with
local floristic elements (often called Nandavanas) have been
specially created near established temples are declared
sacred to ensure their protection and conservation. Such
sacred groves and gardens dedicated to the worship of the
Presiding Deity of each temple are mentioned in ancient
Greek, Latin American and Indian literary works as well as
in epigraphically records and copper plates of these
countries. Data also come from folk traditions, history and
traditional knowledge passed on through several
generations.
Sacred grooves are biologically important places
having maximum species diversity and richness. Besides
this sacred grooves are the significant ecosystem in the
terrestrial biome. Angiosperms are the abundant vegetation
in here, mainly trees and climbers, herbaceous forms are
relatively limited in number, however some pteridophytes,
certain members of Asteraceae, Piperaceae, are substituting
this purpose. In some areas large trees are dominant
whereas in some other areas climbers are majority. The soil
in these places is nutrient rich and water filled, rocky
regions contain members of Riccia, Funaria, Marsilia.etc.
This study includes a Taxonomical approaches to
the Pteridophytic flora in sacred groves. Pteridophytes are
flourished in sacred groves. It’s watery or moisture nature is
suitable for pteridophytes, some are epiphytic forms on tree
members some others are herbs and climber like Lygodium.
Drastic variations among species are common. Sacred
groves are the original replica of natural forests of the
locality. It may comprise of a single tree to a very large
forest tract. It is considered as sacred because of the deity
associated with the grove. Hence it may call as temple
forests, which are one of the oldest forms of conserving
natural forests. This unique community linked forest
conservation concept is followed in many tribal and
agrarian regions of the world.
Pteridophytes constitute an important part of the
world flora. Pteridophytes are of immense economic
importance and there is a great need for their exploitation

towards the economic utility in our day to day life. Ferns
show various economic values towards food and fodder,
biological indicators, bio fertilizers, insect repellants,
medicine and folk remedies. But still the question whether
the full potential of these intriguous plants have been ever
exploited by the humans remains. Quite a large number of
them cultivated as ornamentals either indoors in the houses
or outdoors in the botanical gardens due to their delicate
beauty and grace. The hybrids of different species are now
elegant, expensive, representative members in horticulture.
Another chief economic importance of the pteridophytes is
that their fossil remains contributed to the coal depositions
of the world.Thus we can see that ferns are a group of
unique plants and they have immersed potential to be
studied and utilized in different areas of economic and
academic interest. The current study is a humble attempt to
enumerate and identify the pteridophytic flora of sacred
grooves of the Chalavaragramapanchayath, Ottapalam,
Palakkad, Kerala.
II. MATERIALS AND METHODS
The present study was carried out to assess and
analyse the pteridophytes flora of sacred groves of
Chalavara Grama Panchayath, Palakkad district, Kerala.
The Materials for this study were collected from area of
study during January 2016 to July 2016. Field trips to
various habitats were made during the study period for plant
collection. During the collection, field observations such as
habit, habitat, and date of collection were noted in the field
itself and the diagnostic features of all the specimens were
studied and field notes were made on fresh plant materials.
From the available habitats, sporophytic habits
were collected along with rhizome as far as possible. Plants
collected were carefully handled and covered with
moistened newspapers without causing any harm to the
tender parts. In case of large plants, exact size was noted
down and then the fronds were cut in to pieces, which were
then used to prepare the herbarium. More than one
specimens of each plant were collected for further
identification, observation and herbarium preparation.
About 36 species have been collected from the area. The
colour photographs from the natural habitat were taken
during the collection using digital camera (Sony-Cyber shot
W810). Plants with sporophylls were collected as far as
possible.
Fresh materials were used for the study in the
laboratory. Morphological characters of the sporophytic
plant body were studied. External characters of the spores
and sporangia were also noted in selected plants.
Enumerations of collected specimens were done by
observing a morphological feature under stereozoom
microscope (LABOMED D500) Identification of the
specimens was done by using the Pteridophytes flora of the
Western Ghats- South India (Manickam and Irudayaraj
1992). All the identified species of ferns have been
classified and arranged according to Smith et al., 2006 with
some modification as per Fraser-Jenkins (2009), regarding
their correct nomenclature and classification of fern allies.
The collected specimens were properly processes
as herbarium specimens, carefully spread on the newspaper.
The large sized plants were bent into V or W shapes and
these specimens were bound tightly in plant press. The
newspaper sheets were changed regularly until the
specimens got dried completely. The dried specimens were
mounted on herbarium sheets by using synthetic gum. The
herbarium sheets were neatly labeled by using the details
from the field note book. All the herbaria prepared for the
present study were deposited in Sree Krishna College
herbarium.
III. RESULTS AND DISCUSSION
Fern and fern allies are almost neglected group of
plants distributed all over the world. They are live in a wide
variety of habitats from remote mountain elevations to dry
desert rock faces, to bodies of water or in open fields. Some
ferns are serious weed species. The present study revealed
the occurrence of 26 species of pteridophytes in the sacred
groves of Chalavara Grama Panchayath. This belongs to 20
genera under 14 families. Based on their habitats various
members of fern and fern allies are classified in to
following categories, out of 26 species21 species are (81%)
terrestrial, 2 species are (8%) aquatic and 3 species are
(11%) epiphytes. (Table 1).
The present study identified 2 ecologically
significant species such as Salvinia molesta (African payal)
and Marsilea minuta as their wide distribution as weeds in
ponds and paddy fields. Salvinia molesta, a free floating
aquatic fern, is one of the World’s worst aquatic weeds
(Madhusoodanan, 1989). As the plant die, organic debris
accumulates at the bottom of the water column and can
threaten fisheries by creating a shallow – water environment
less suited to fish breeding (Sculthrope, 1985). Pyrrosia
heterophylla growing as epiphyte in less polluted area, their
absence indicates pollution (this species only obtained
from). A detailed survey on the fern flora of a particular
region becomes significant only if it can do any good to the
conservation practices of these endangered plants. Lack of
knowledge or rather interest among Botanists is one of the
main reasons for negligence faced by ferns. So familiarizing
ferns and including them with almost equal importance to

the Angiosperms is a way out from the threatened status of
these plants. The economic and medicinal use of them
should be explored more and by this ferns can attain a
significant position I plant kingdom. Prior to all this all the
manipulations and misidentifications of these plants should
be rectified for adopting better conservation strategies and
for exploring the wide applications of these plants to be
used for the betterment of mankind and life on earth as a
whole.
