Materials Today: Proceedings 2019年 14卷 574-579页

作者： T. Pushpa Malini J. Arockia Selvi M. Arthanareeswari P. Kamaraj Department of Chemistry SRM University Kattankulathur – 603 203 Tamil Nadu India Department of Chemistry Vel Tech Rangarajan Dr.Sagunthala R&D Institute of Science and Technology Avadi Chennai 600062 Tamil Nadu India

Photocatalytic degradation of anilofos was studied using TiO 2 (degussa P-25)as catalyst in aqueous solution under direct sunlight. The influence of catalyst loading, temperature, herbicide concentration, pH, presence of ions, surfactant and radiant flux on the rate of oxidation of anilofos were investigated. The solar irradiated samples were analyzed by a validated HPLC method [1]. rapid dissipation of herbicide was observed by using TiO 2 (degussa P-25) catalyst @ 0.5g/l TiO 2 . The rate of degradation was found to increase with the increase in the temperature from 40°C to 70°C. The influence of cations on the degradation rate was in the order Fe 2+ , Cu 2+ >Zn 2+ >Ni 2+ >Mn 2+ > Co 2+ and for anions Cl - , HClo 3 - > CO 3 2- , So 4 2- . The rate was decreased as the pH was increased from 4.0 to 8.0. But at very high alkaline condition (pH 10.0) the rate was found to be the maximum. The surfactant sodium dodecyl sulphate(SdS) showed much influence when compared to other surfactants studied. When the study was conducted at three different radiant flux (109 Lux, 655 x 10 1 Lux, and 601 x 10 2 to 1074 x 10 2 Lux), it was observed that the rate was faster under the day light flux 601 x 10 2 to 1074 x 10 2 Lux. The anilofos degradation rate was found to follow the first order kinetics. These conditions were then applied for the treatment of ground water and effluent.

The COVId-19 is contagious and menacing, it is more obscure in identifying the infections in primary stage as it able to thrive in both hot and cold conditions. So, in this paper we have developed the Susceptible Vaccinated Infected recovered (SVIr) model utilising the Michaelis-Menten Functional response to explain the infections of COVId-19 especially for diabetic who are having more chances of getting infected as they are already vulnerable due to their lack of immunity. We also considered non-diabetic patients and discussed the symptomatic and asymptomatic infections for both diabetic and non-diabetic patients as well as the recuperation from COVId-19 (Coronavirus disease). We have found the uncertainty in the rate of change variables, so we used the fuzzy concept to lower the uncertainty and find a better model. For this environment, we have used Trapezoidal Numbers(TFN) and fuzzified the rate of change variables and by using the Partition defuzzification Method(PdM) we defuzzified the values and got accurate results. Additionally, using Python programming, we compared the variations between the crisp and fuzzy models and we also discussed the equilibrium points, performed sensitivity analysis, and examined the stability of the model.

Autism spectrum disorder is a mental imbalance disorder. research has distinguished that youngsters with Autism Spectrum disorders (ASd) as a rule show challenges in language securing, proficiency improvement, and social association. Albeit broad examinations have been led to portray shortages in language and social attitudes among youngsters with Autism range issue, inquire about on the proficiency advancement of this gathering is as yet meagre. This is the most valuable data for neurons to take care of a specific issue in light of the fact that the weight typically energizes or hinders the sign that is being conveyed. They will include the provision of information and advocacy, assessment, early intervention therapies, help at school, behavioral support, individual support, supported accommodation and respite. The National Autistic Society's Pledges initiative, which offers neuro-typical people 18 ways to alter their behaviour in order to help friends and colleagues on the spectrum, they seemed really obvious. Every neuron has an inner state, which is called an actuation signal. Mental imbalance conduct expectation technique helps in dealing with the Autism lack utilizing a few grouping calculations and Neural Networks.

The Biodiesel is an alternative fuel which can be produced from various feedstocks like vegetable oils, seeds, animal fats and animal tallow. In-case of oil it will be extracted from the seeds with the help of an expelling process. Chemical expelling is efficient method to extract oil from the seeds when compared to mechanical expelling. due to lower production cost mechanical expelling will be used in most of the cases. This oil consists of FFA content, Based on FFA content single step/two step transterification process will be followed. In this Linseed oil the FFA content is 1.87, hence single step transterification process is followed. The triglyceride esters will be converted into the Mono-glyceride by a catalyzed reaction. The reaction conditions generally involve a trade-off between reaction time and temperature as reaction completeness is the most critical fuel quality parameter. Much of the process complexity originates from contaminants in the feedstock, such as water and free fatty acids, or impurities in the final product, such as methanol, free glycerol, and soap. Processes have been developed to produce biodiesel from high free fatty acid feedstocks, such as recycled restaurant grease, animal fats, and soap stock. This linseed seed has been tested with FTIr analysis, GC-MS analysis and physical properties. All the properties are satisfying the ASTM standards. The physical properties of the linseed biodiesel has been incorporated.

Atomized spray cutting fluid (ASCF) is a sophisticated machining technique that achieves higher productivity, enhanced surface quality, extended tool life, and cost benefits. This research aims to analyze the influence of cutting process parameters on Inconel 718 alloy turning in dry and ASCF cutting environments. The critical machining indices such as surface roughness, machining cost, power consumption, and tool life were analyzed concerning these two cooling environments. The cutting parameters were optimized using desirability functional analysis and two types of multicriteria decision making (MCdM) method, such as additive ratio assessment method (ArAS) and combinative distance-based assessment (COdAS) method, were investigated. The composite desirability index (Cd) of optimum parameter setting(A2B1C2d2) is improved by 6.34 % compared to the initial parameter setting (A2B1C2d1). The optimum parameters from the MCdM technique are obtained as a cutting speed of 200 m/min, feed rate of 0.08 mm/rev, and depth of cut of 0.2 mm under ASCF environment. ASCF machining significantly minimize the surface roughness, machining cost and power consumption, maximize the tool life by about 16%, 51%, 17% and 48% respectively as compared with dry machining © 2021, CC BY.

Clustering has proven to be an effective method in the medical field for finding patterns in labelled and unlabelled datasets. This work is implemented over whole body CT scans (∼1TB) of 3500 patients in form of unlabelled dICOM images. The whole-body CT images have been anonymized for 30 attributes based on dICOM regulations and the Brain images alone are segmented using the dICOM tag element called 'Protocol stack'. The segmented Brain images are efficiently grouped based on visual similarity using K-means clustering after performing feature extraction and dimensionality reduction. The results of the clustering can be furtherutilized by radiologists to perform labelling or find patterns in Brain CT scans of patients that are difficult where each scan consists of a varying number of slices during detection of Internal Bleeding. The efficiency of K-means is analyzed by performing computation over a different number of clusters (K) by applying silhouette scores to find optimal cluster.
