:Graphics processing unit (GPU) is a computer programmable chip that could perform rapid mathematical operations that can be accelerated with massive parallelism. In the early days, central processing unit (CPU) was responsible for all computations irrespective of whether it is feasible for parallel computation. However, in recent years GPUs are increasingly used for massively parallel computing applications, such as training Deep Neural Networks. GPU’s performance monitoring plays a key role in this new era since GPUs serve an inevitable role in increasing the speed of analysis of the developed system. GPU administration comes in picture to efficiently utilize the GPU when we deal with multiple workloads to run on the same hardware.

In this presentation, we have discussed the synthesis and characterization of a new nano photocatalyst system (Cu-Trp-Ilu/MWCNTs) utilizing the potent carbon nanotubes, Multiwalled Carbon Nanotubes. The MWCNTs were synthesised by our new simple chemical approach under less harsh conditions, compared to very harsher physical approaches. Doping of the interesting Copper bioinorganic complex, Copper-Tryptophan-Isoleucine with MWCNTs was achieved via a facile synthetic approach would be presented. The SEM image of the Nano photo catalyst shows the immersion of bioinorganic complex (Cu-Trp-Ilu) within a pool of MWCNTs and forming the Nanocatalyst system, (Cu-Trp-Ilu/MWCNTs).The obtained (Cu-Trp-Ilu/MWCNTs) was employed in numerable applications such as sensors, measuring the pesticide concentration in food products, adsorption of heavy metals from drinking water and bioanalysis of blood and urine samples.

Aegle marmelos fruit is packed with immense medicinal properties. The main objective of the studywas to assess and compare the phytochemical potency, antioxidant capacity and anti-inflammatory activity of unripe, ripe and overripe fruits. The fruit pulp was dried and extract (ripe fruit) was prepared in various solvents. Phytochemical assessment was done and the solvent which exhibited maximum potency was chosen as unripe and ripe fruit solvents. Phytochemical assessment, estimation of phenols (FolinCiocalteau method), antioxidant capacity (Molybdate method), anti-inflammatory activity (membrane stabilization property method) and Free radical scavenging capacity for hydroxyl, hydrogen peroxide and DPPH free radicals were carried out. The phytochemical screening of the ripe fruit showed maximum intensity in hydroethanolic extract. On comparison, ripe fruit extract possessed a greater phytochemical potency, antioxidant capacity and inhibition against hydroxyl, hydrogen peroxide, DPPH radicals. The total phenolic content of the over ripe fruit was high. The anti-inflammatory activity of unripe fruit was slightly higher than ripe fruit. This signifies that phytochemical potency and functional properties of the fruit differs with maturity stages.

The waste water generated from the boys hostel and girls hostel SIT campus were collected andanalyzed. Conventional treatment method and the method of purification using Reed bed for the treatment of effluent were compared. The plant used for this purpose was Setaria italica and ornamental plant which is locally known as Foxtail millet (Thinai) and Flax lily. The experiment was conducted with the Primary treated sewage taken from the Sewage Treatment Plant (SIT STP) of our campus. From the experiment it is found that the one with Reed Bed system givesa better quality treated water vis-à-vis the campus STP treated water. Hence, the filter bed of SIT STP is planted with Setaria italica and ornamental plant as a trial run. The project presents the method of construction of root zone bed and the effectiveness of removal of various contaminants using this root zone treatment process. The results for raw water and treated water samples were compared and discussed

: This Study Statistically analyzes the deteriorating water quality of the River Ganga. Statistical techniques such as Water Quality index (WQI), Cluster Analysis, Best Subsets Regression and Multiple Regression Analysis were applied to seven water quality parameters, collected from 21 sampling Stations in India. Water Quality Index identified the most polluted stations that are Kadaghat, Allahabad, Khurgi, Patna U/S, Bihar, Varanasi D/S (Malviya Bridge), U.P, Indrapuri, Dehri and Varanasi U/S (ASSIGHAT), U.P. Cluster Analysis for the different Stations showed a similarity of 99.99% between the stations Ganga D/S, Mirzapur , Varanasi D/S (Malviya Bridge) and Varanasi U/S (Assighat), U.P. Cluster Analysis for variables showed a 98.96% similarity of parameter BOD with WQI and 96.06% similarity between the parameters Total Coliform and Fecal Coliform. After applied the Best Subset Regression Analysis we get the highest Mallow c-p value with high R2 for the parameters BOD, Nitrate, Total Coliform and Fecal Coliform. In the Regression analysis the p value for the estimated coefficients of BOD is 0.00, indicates that BOD is significantly related to WQI.In this paper we conclude that BOD is the most critical parameter and we study the comparison of water quality of river Ganga for different stations.

Globalization and urbanization growth are disbalancing the nature by creating technology and by increasing population respectively. Population growth is generating trash including the non-renewable ones. Use and throw objects came into existence and as a result, created wastes. After decades, the waste is generating beyond limits that it has created the mountain like piles in the landfills, which is creating hazards for the environment and human health. A better approach to reduce the waste is to recycle and reuse them as an alternative solution to building material industry. The question which arises here is that if wastes should be recycled or reused; what all are the waste materials which can be reused in building material industry without harming the environment. The recycling of waste materials produces lot of demerits to environment and human health. Polyethylene and rubber tires are being used in preparing the roads, plastic bottles are being used to build walls, fly ash is used in bricks etc. measures are being taken. The research paper will try to do a detailed SWOT analysis to find a suitable reusable waste material for building material industry, which will be environment friendly. The plastic waste, construction demolition waste and transport industry waste are the wastes that can be reused as building materials. The 3 wastes have the ability to withstand calamities and loads, are easy to build with, cheap, clean and has passed the structural tests. The paper intends to provide the information regarding the construction with the help of the 3 materials. This approach will help to manage the waste, build a sustainable environment, lower the greenhouse gases, maintain the natural resources etc.

:The increasing consumers’ demands to acquire healthier fruits and vegetables as well as the urgency in looking to natural compounds with antioxidant activity (AOA) has encouraged a quick expansion of research studies about phenolic in vegetables. Gourd vegetables refer to the fruits of plants in the two Cucurbitaceae genera Lagenaria and Curcubita. There is a diverse source of polyphenols in plant materials. Method: Seven gourd vegetables grown conventionally (CV) were collected from the local market and a set of the same vegetables from certified organic farms (OG). They were analysed for the total phenolic (TP) content by the Folin-Ciocalteu method using Gallic acid as standard. Earlier each vegetable was extracted with ethanol, methanol and water separately for the estimation of TP. The TP content was expressed as µg of GAE/ g of FW. Results: Bitter gourd had the highest amounts of TP in both the conventional (1766.52 µg of GAE/ g of FW)) and organic (1962.0 µg of GAE/ g of FW)) samples. Conventional gourd vegetables had more TP when compared to organic varieties. Among the solvents the extraction of phenolics was the highest in water followed by methanol and ethanol. Conclusion: Gourd vegetables are widely available and can contribute significant amounts of phenolics to the diet
当前位置消费者对获取更健康的水果和蔬菜的需求日益增加，以及对具有抗氧化活性的天然化合物(AOA)的迫切需要，促使了对蔬菜中酚类物质的研究迅速扩大。葫芦菜是指葫芦科和葫芦科两种植物的果实。植物材料中多酚的来源多种多样。方法:从当地市场收集了7种常规种植的葫芦菜(CV)，并从认证有机农场(OG)收集了一套相同的蔬菜。用Folin-Ciocalteu法测定总酚(TP)含量，以没食子酸为标准品。前期分别用乙醇、甲醇和水提取每一种蔬菜的总磷。TP含量以µg / g FW表示。结果:在常规样品(GAE/ g FW 1766.52µg)和有机样品(GAE/ g ofFW 1962.0µg)中，苦瓜TP含量最高。与有机品种相比，传统的葫芦类蔬菜含有更多的总磷。在溶剂中，水对酚类物质的提取率最高，其次是甲醇和乙醇。结论:葫芦类蔬菜广泛存在，可以为饮食提供大量的酚类物质
