Abstract: The bioactive compounds of Allium sativum was carried out using essential oil from the spice. The SEM shows the shapes, dispersion and agglomeration of the sample, while the EDX confirms the SEM and the presence of some compounds; Ag L (Silver iodide), Ci K (Potassium chloride), C K (Cyanogen chloride), P K (Phenol), S K (Potassium). The FT-IR reveal the AgNPS. capping and reducing the particular biomolecule from the functional group for identification. The 11 bioactive compounds of Allium sativum viewed on the GC-MS has shown to have different antioxidant role they play in human health and body. The DPPH of AgNPs Allium sativum was higher at 500μg/ml and has a concentration dependency than the methanol Allium sativum, but Allium sativum methanol is higher than the AgNPs as represented in the IC50 table. The reducing power of Allium sativum methanol was higher than the Allium sativum AgNPS. Therefore, Allium sativum can be beneficial in nutraceuticals industry.

Abstract: Why whales are stranding on beaches across the oceans, and kill themselves, is a question to which none of those who study their way of life could not give an answer. By converting solar energy into matter on earth, it increases the weight of our planet (geological layers,) and its gravity. This makes difficulties to bulky whales, and their maintain, and constantly swimming in the water. Fatigue, due to weakening hearts, and the increasing force of gravity, forces each of them to seek rest on the sandy beaches across the oceans. Stranded, rested, alone, whales are not possible to return to oceans. Because of the same reason, from dinosaurs survived only birds, creeper's reptiles, and crocodiles, which could take rest on the solid ground

Abstract: Reduction of automobile crash death was ever amongst the best health achievement of the 20th century. However, quite 32,000 are killed and a couple of million are injured annually from automobile crashes. The purpose of this study is to compare and analyse motor vehicle crash fatality rate in both metropolitan and non-metropolitan areas of Alabama. Data obtained from the US Department of Health and Human Services, National Highway Traffic Safety Administration and US Department of Transportation between 2005 to 2018. Regression analysis was used in this study to identify the relationships between MVT fatality rate and various factors like speed driving, blood alcohol concentration (BAC), gender, age, and role of daytime, night-time, weekdays, and weekends. It helps understand the fictional interaction and accuracy between factors or variables. The multivariate linear regression analysis is performed to investigate the effect of individual factors in this study. Descriptive analysis is also used to understand the MVT fatality rate of metropolitan and non-metropolitan populations of Alabama from 2005.........

Abstract: The influence of mixtures of metals and pesticide on the activity of algal hydrolytic enzyme was investigated. Toxicity of unary, and binary combinations of Copper (Cu2+), Zinc (Zn2+), Lead (Pb2+), Chromium (Cr2+), Cadmium (Cd2+) ions and 2,4-dichlorophenoxyacetic acid (2,4-D) was assessed via inhibition of phosphatase enzyme activity of Chlorella vulgaris. The unary ions of Cu2+, Zn2+, Pb2+, Cr2+, Cd2+ and 2,4-dichlorophenoxyacetic acid (2,4-D) effect on phosphatase activity of Chlorella vulgaris was assessed by inhibition of conversion of p-nitrophenylphosphate to p-Nitrophenol at optical density (OD) of 410nm. Results obtained from the study for experimental data points and model-predicted dose-response data for inhibition of phosphatase enzymatic activity showed that all the metal ions were all toxic to algal phosphatase activity by the gradual reduction of the coloured p-Nitrophenol..........

Abstract: Opportune utilisation of water can help protect the environment and minimise energy used to process and pump water for daily use. Rainwater is considered a renewable resource and the system of harvesting is sustainable, which can help in reducing vulnerability to climate change. Due to water scarcity, domestic rooftop rainwater harvesting (DRWH) is being practiced in Imphal as an alternative source of water for the urban water supply. However, not all households are aware of the potential of rainwater harvesting. This indicates that the climatic water availability to be quantified determines rainwater potential. DRWH also minimises water bills and lowers water demand. Regardless of its benefits....
