Turbidity

Extensive human and mechanical activities accelerate the rate and amount of seashore erosion and results in higher turbidity of seawater. Impact of shipbreaking on inter-tidal sediments and soils: Various refuse and disposable materials are discharged and spilled from scrapped ships and often get mixed with the sand. The scraps from the ships are staked on the sea…

Contamination is the presence of an unwanted impurity in a material.Contaminated water can be a source of deadly diseases, such as cholera and dysentery. Cholera an infectious disease that can cause severe watery diarrhea, dehydration, and death. Dysentery is an inflammation of the intestines, especially the colon, that often causes severe diarrhea with blood or mucus in the feces. Impurity is the quality or condition of being impure. particle is a minute fragment or quantity of matter.…

Phyllanthus niruri Extracts of Phyllanthus niruri have been studied for biological activities in various animal models and in vitro models and reported to possess significant antimicrobial, antiviral, hepato protective, antioxidant, anticancer, anti-inflammatory, antiplasmodial, antiurolithiatic and diuretic. The phytochemical studies were characterized and the presence of various compounds such as lignans, phyllanthin, hypophyllanthin, flavonoids, glycosinoids & tannins was mentioned (Narendra…

antibiotics in a growth medium and dispensed into the test tubes. A standardized bacterial suspension of 1–5×105CFU/mL is introduced into tubes. The tubes are incubated overnight at 35°C, they are then observed for visible bacterial growth in form of turbidity (Jorgensen and Ferraro,2009). The core advantage of this process is it produces quantitative data allowing data to be precise and clear-cut. Allowing data to be generalisable, however research has critiqued the macrodilution method as…

To determine how two different weed species, A. Pinnata and N. Alba, and their accompanying biotic and abiotic factors live in the fresh water eco-system that has been studied, Jake’s Hole. The investigation that was conducted comprised of taking different samples of data over four weeks from the same four sections of the dam, out of a 1m x 1m square. The final results show that A. Pinnata is predominantly the weed species that inhabits the eco-system compared to N. Alba, where there is very…

hydration method with different concentration of surfactant (Span80, Tween80, and Sodium Deoxycholate) and soya lecithin and characterized for various parameters including Vesicles Size, Morphology, Entrapment Efficiency, Drug Loading Capacity, Turbidity measurement and Stability Evaluation. Optimization of the formulations was done by selecting three process variables: a) concentration of soya lecithin b) concentration of surfactants (Sodium deoxycholate, Tween 80 and span80) and c)…

Protein Purification Practical Report Student Name : Noel Murphy Date : 28 February 2015 UF/DF Practical Question Report Ultrafiltration (UF) and Diafiltration (DF) steps are carried out prior to every chromatography step and post the final polishing chromatography step. These UF and DF steps are vitally important, the UF step concentrates the protein product into a smaller volume of buffer, while the DF step alters the conditions the protein product is sitting in i.e. Buffer exchange.…

The gas generation is due to E. coli metabolic processes that generates acid and changing the turbidity. 2. The Membrane Filtration Method did work as well. MF method can replace the MNP test for microbiological analysis of water sample. After the incubation of the mEndo plate for 24 hours it is perceptible the grown of E. coli colonies across…

caused by impurities that are streaming the ocean waters in which ventured through storm drains of runoff water. To go more in depth, water qualities of Pismo is measured through samples coming from the salty liquid that is analyzed by color, odor, turbidity, and acidity. Depending on the value, waters with poor conditions can become infected with bacteria that can cause infectious illnesses. Illnesses like “stomach flu, ear infections, and skin rashes” advocating that serious cons of…

Evaluating overall results compiled by practical investigations, the water sample showed very positive results with very minimal flaws in its purity. Observing the physical properties of the sample it had no turbidity and looked relevantly clear. Data shown here may be inaccurate due to many varied factors in the lab testing. Most of the testing heavily relied on the judgment of the human eye to compare charts colours possibly resulting in human error. A low 5 m/L’s was tested each time when…
