In order to assessing whether algae can reduce the pollution concentration of the effluents by
absorbing the nutrients, it is found that effluents can effectively be treated by employing algal organisisms such
as Oscillatoria and Stigeoclonium species and these organisms are frequently found in the polluted waters and
they were recorded as pollution tolerant forms. In the laboratory procedures out of the several media tested
Modified CHU No. 10 medium was found to be quite suitable for both the test organisms. It was found that up to
87% and 85% of phosphate uptake was achieved by Oscillatoria and Stigeoclonium respectively with 13% and
16% increase of D.O. in the effluents by the tenth day. In case of organic matter Oscillatoria removed 73% and
Stigeoclonium 70% up to tenth day

This document summarizes a study characterizing Pseudomonas aeruginosa strains isolated from drinking water distribution systems in Morocco. The study examined the virulence phenotypes, biofilm formation ability, and physicochemical properties of the P. aeruginosa isolates.
The results showed that the isolates expressed a range of virulence factors including proteases, lipases, and hemolysins. Most isolates were motile and able to form biofilms on polyethylene surfaces within 8-12 hours. Physicochemical characterization found the isolates possessed a range of surface properties like hydrophobicity/hydrophilicity that influence their ability to adhere to surfaces. Scanning electron microscopy images showed cell adhesion and biofilm formation on polyethylene over time.
In summary, the study
Study on the effect of pollution on some vegetable crops
This study examined the effects of vehicle pollution on the growth, yield, and heavy metal content of spinach, squash, and turnip plants grown at different distances from a road with high traffic density. Two field experiments were conducted over two growing seasons. The study found that vegetative growth, yield, and nutrient levels decreased with decreasing distance from the road, while heavy metal levels of lead and cadmium increased. Washing the edible parts of the crops reduced heavy metal content by 10-30%, with washing being more effective at removing lead than cadmium. Leafy spinach contained higher heavy metal levels than the other crops. The results suggest cultivating vegetables at least 80 meters from roads and washing produce to reduce heavy metal consumption

We analyzed the Chromium (VI) removal capacity in aqueous solution by the Persea americana biomass, using the diphenyl carbazide method to evaluate the metal concentration. Biosorption at different pH (1, 2, 3, and 4) was evaluate for different times. We too studied the effect of temperature in the range of 28 to 60 °C and the removal at different initial concentrations of Cr (VI) of 200 to 1000mg/L. Therefore, the highest biosorption of the metal (50mg/L) occurs within 270 minutes, at pH of 1.0 and 28 °C. According to temperature, the highest removal was observing at 60 °C, in 45 minutes, when the metal is completely adsorbed. At the analyzed concentrations of Cr (VI), fungal biomass, showed excellent removal capacity, besides it removes efficiently the metal in situ (100% removal in earth and water contaminated, after 5 and 6 days of incubation, 5 and 10g of biomass, 10g of earth and 100mL of water; so, it can be used to eliminate it from industrial wastewater.

Abstract The present work deals with the screening of microorganisms Candida rugosa NCIM 3467 and Penicillum citrinum NCIM 765 with different agro residues – rice bran, wheat bran, groundnut oil cake, coconut oil cake and sesame oil cake for maximum production of lipase. Among all the industrial residues, Groundnut oil cake supported the maximum lipase production by C.rugosa NCIM 3467. The physical factors such as fermentation time, temperature, pH, inoculum age, inoculum level, initial moisture content played a vital role in lipase production and further the yield was improved with the supplementation of carbon and organic nitrogen sources to the solid medium. At 5 days of fermentation, 32 °C, pH 6, 5 day old culture, 15% inoculum level and at 60% initial moisture content, lipase activity of 57.25 U/ml was obtained. Further the activity was raised to 63.35 U/ml by supplementing the substrate media with maltose (5%w/w) and peptone (3%w/w).

Abstract
Water is the elixir of life, a precious gift of nature to all the living species on earth. It is rapidly becoming a scare commodity in most parts of the world. Only 0.35% of the total availability of water found in lakes and wetlands and 0.01% in rivers and streams which are likely getting depleted due to the discharge of the effluents such as dyes simultaneously increases the water quality parameters. Malachite green is a common textile dye being discharged in lake water situated near textile industries. The phycoremediation method employs the use of algae, say, Chlorella pyrenoidosa which helps in decolorizing the water and due to its growth in the lake water, the physico-chemical parameters higher in the polluted water found to be reduced and water can be used for various purposes. The trails were made using Chlorella pyrenoidosa and Malachite green at different concentrations. The optimum concentration for the degradation of dye was completely done at the concentration 15 mg confirming the decolorization capacity by Chlorella pyrenoidosa. The same experiment was performed with adjusting the pH at 6, 7 and 8. Optimum pH for the dye degradation was found as pH 7 at which all the concentrations Chlorella pyrenoidosa was able to degrade the dye with the decolourization capacity of above 95%. The phyico-chemical parameters checked after the decolorization by Chlorella were found to be within the limits and thus Chlorella which is available in nature can be used in the decolorization of effluent water by eco-friendly method.

Utilization of Banana Peel Powder in Concrete A Result
This document summarizes a study that analyzed the properties of concrete when banana peel powder is used as an admixture. The study found that the percentage of heat transmitted through concrete cubes and the time taken for the cubes to cool down were both reduced when banana peel powder was added, indicating that the exothermic chemical reaction in the concrete was decreased. Specifically, the heat transmitted was reduced by 12-16% and the cooling time was reduced by 2.5-4% compared to normal concrete without banana peel powder. The flexural strength of the concrete increased slightly with the addition of banana peel powder but the compressive strength did not change significantly. Therefore, the study concluded that banana peel powder can be used as a concrete admixture

The use of fossil fuels is unsustainable due to limited supply and also due to large
emissions of Carbon dioxide due to the effect of global warming. Biofuel is a viable
option but can, as produced today; only provide a limited amount of fuels needed.
Biofuels are presently derived from terrestrial plants, which require large amounts of
arable land. Biofuels from microalgae on the other hand do not necessarily require
arable land and can theoretically replace fossil fuels absolutely. Biofuels from
microalgae could use industry waste water as growth medium particularly paper
industry waste water is an interesting potential provider due to its high nitrogen and
phosphorus in waste water. In this research work marine microalgae Nannochloropsis
Salina was cultivated using f/2 medium using modified air lift photo-bioreactor along
with the paper industry effluent waste water, The doubling time calculated from
optical density attained at 48 hrs the cell count almost doubled during this period.
Since the marine species is sensitive to pH we need to maintain the pH at 7 below
7indicated the decreased biomass levels in culture. The lipid extraction was studied
using solvent methods. The functional compounds in lipids FAME were studied using
GC-MS analysis, the Nannochloropsis salina showed qualities of growing in fresh
water and brackish water apart from the marine water which is a desirable
characteristic for algal phycoremediation

Utilization of Banana Peel Powder in Concrete A Result
This document summarizes a study that analyzed the properties of concrete when banana peel powder is used as an admixture. The study found that the percentage of heat transmitted through concrete cubes and the time taken for the cubes to cool down were both reduced when banana peel powder was added, indicating that the exothermic chemical reaction in the concrete was decreased. Specifically, the heat transmitted was reduced by 12-16% and the cooling time was reduced by 2.5-4% compared to normal concrete without banana peel powder. The flexural strength of the concrete increased slightly with the addition of banana peel powder but the compressive strength did not change significantly. Therefore, the study concluded that banana peel powder can be used as a concrete admixture

The use of fossil fuels is unsustainable due to limited supply and also due to large
emissions of Carbon dioxide due to the effect of global warming. Biofuel is a viable
option but can, as produced today; only provide a limited amount of fuels needed.
Biofuels are presently derived from terrestrial plants, which require large amounts of
arable land. Biofuels from microalgae on the other hand do not necessarily require
arable land and can theoretically replace fossil fuels absolutely. Biofuels from
microalgae could use industry waste water as growth medium particularly paper
industry waste water is an interesting potential provider due to its high nitrogen and
phosphorus in waste water. In this research work marine microalgae Nannochloropsis
Salina was cultivated using f/2 medium using modified air lift photo-bioreactor along
with the paper industry effluent waste water, The doubling time calculated from
optical density attained at 48 hrs the cell count almost doubled during this period.
Since the marine species is sensitive to pH we need to maintain the pH at 7 below
7indicated the decreased biomass levels in culture. The lipid extraction was studied
using solvent methods. The functional compounds in lipids FAME were studied using
GC-MS analysis, the Nannochloropsis salina showed qualities of growing in fresh
water and brackish water apart from the marine water which is a desirable
characteristic for algal phycoremediation

IRJET - Production of Protease by Actinomycetes under Submerged Fermentation
1. Actinomycetes isolated from marine sediments were screened for protease production. Isolate B22 showed protease activity on starch casein agar plates.
2. Fermentation conditions like incubation time, temperature, pH, and inoculum age were optimized for B22 to maximize protease production.
3. Under optimized conditions of 5 days incubation at 30°C, initial pH of 5.0, and using a 6th day old inoculum, B22 produced a maximum of 46.13 U/mL of protease.

1) The paper presents a probability analysis of slope stability using the Monte Carlo simulation method to account for uncertainty in parameters like pore water pressure, cohesion, and internal angle of friction.
2) The results of the Monte Carlo simulation method are compared to other recognized methods of slope stability analysis like Bishop simplified, Fellenuis, Janbu simplified and corrected, Spencer and Lowe-Karafiath which use limit equilibrium.
3) The probability analysis finds that the failure probability is most affected by the standard deviation of pore water pressure, cohesion, internal angle of friction, and correlation coefficient between parameters, though individual limit equilibrium methods only account for one of these parameters in each analysis.

Nippon Hotel, İstanbul-TurkeySome Biochemical Markers that Can Predict Pre-Eclampsia
This document summarizes an abstract from the 9th International Scientific Conference on Applied Sciences and Engineering. The abstract discusses some biochemical markers that can predict pre-eclampsia. It states that tumor necrosis factor alpha (TNF-α) directly damages vascular endothelial cells and increases endothelial permeability, which may result in secretion of vasoactive substances and increased vascular permeability and coagulation. This involvement of TNF-α in the pathogenesis of pre-eclampsia means it may identify patients at high risk for the condition and serve as a marker of severity. Preeclamptic women also have abnormal lipid metabolism and profiles due to pre-eclampsia, and this alteration in lipid metabolism may play a key role in developing symptoms.

Optimization of a Cryopreservation Protocol for the Malaysian Fresh Water Microalgal Strain
- 1. Abstract of Applied Sciences and Engineering, 2015, Vol.4 DOI: 10.18488/journal.1001/2015.4/1001.4 4th International Scientific Conference on Applied Sciences and Engineering 3-4 October, 2015 Langkawi Lagoon Resort, Malaysia Conference Website: www.scihost.org 3 Paper ID: 32/15/4 th ISCASE Optimization of a Cryopreservation Protocol for the Malaysian Fresh Water Microalgal Strain Nor AfiqahBinti Anua1 --- SitiSaizahBtMd Said2 Abstract Microalgae is important in many biotechnological exploitations in producing valuable products, services and processes. The technology of cryopreservation is useful in the long-term storage of many microalgal strains able to survive post cryopreservation. In this study, Chlorella vulgaris was conducted to determine the effects of different concentrations of cryoprotectant to preserve the fresh water microalgal strain employing three types of protocol. Dimethyl sulfoxide (DMSO) with different concentrations of 0%, 10%, 20% and 30% were added to the microalgal suspension in three types of protocol. Protocol 1 involves direct plunging into liquid nitrogen, Protocol 2 is slow cooling to -80 °C and Protocol 3 is slow cooling to -20 °C. The absorbance value at 540nm was used as as measurement to determine the growth post cryopreservation. The absorbance value with 30% DMSO in Protocol 2 showed the highest at 0.387 + 0.015 and was significant at p<0.05 compared to Protocol 1 and 3. The best protocol for the cryopreservation of Chlorella vulgaris was Protocol 2 using slow cooling to -80 °C treated with 30% DMSO as the cryoprotective agent.
