Effects of Temperature on Tribological Properties of Al2O3-TiO2 Coating

The Al2O3-TiO2 coating for turbine blades is being used since long. During the last decades,a large number of papers have been published, but work on property assessment of Al2O3-TiO2coating on rotating component from tribological point of view is very less. This paper assessesthe wear behaviour of  Al2O3-TiO2 coating on inconel 601. The Al2O3-TiO2 coating on inconel 601is deposited by plasma spray process. The SEM results show that above 300 oC, the frictioncoefficient decreases due to softening of coating material. The wear rate increases with increasein temperature. The coating showed brittle fracture at higher temperature. Other test results haveshown the drastic changes in property due to load and temperature.Defence Science Journal, 2008, 58(4), pp.582-587, DOI:http://dx.doi.org/10.14429/dsj.58.168

Comparison of the antioxidant activity and total phenolic, flavonoid content of aerial part of Cleome viscosa L.

Cleome viscosa L. (Capparidaceae), commonly known as “wild mustard”, is an annual, sticky herb found as common weed all over the plains of India and throughout the tropics of the world. In traditional systems of medicine the plant is reported to possess beneficial effects as an anthelmintic, antiseptic, carminative, antiscorbutic, febrifuge, and cardiac stimulant.     The aim of the present study was to evaluate to antioxidant activity of 70% methnolic extract of leaf and stem part of Cleome viscosa (CV) by using different in vitro model such as β carotene bleaching assay, reducing power and free radical scavenging activity (DPPH and hydroxyl radical scavenging activity). Total phenolic content were estimated by the Folin–Ciocalteu colorimetric method using gallic acid as standard and expressed as mg/g gallic acid equivalent (GAE) and total flavonoid content was estimated by aluminium chloride colourimetric method. The total phenolic, flavonoid content and antioxidant activity of Cleome viscosa leaves were found to be 66.38±0.82mg/g, 0.54±0.04mg/g and 77.30% respectively. Cleome viscosa leaves showed high free radical scavenging activity as evidenced by the low IC50 values in both DPPH (1,1-diphenyl-2-picryl hydrazyl) (373.18 μg/ml) and hydroxyl radical (573.55 μg/ml) methods. Cleome viscosa leaves possess high phenolic, flavonoid content and potential antioxidant activity, reducing power and free radical scavenging activity in comparison to stem

Comparative Analysis of Metaheuristic Approaches for Makespan Minimization for No Wait Flow Shop Scheduling Problem

This paper provides comparative analysis of various metaheuristic approaches for m-machine no wait flow shop scheduling (NWFSS) problem with makespan as an optimality criterion. NWFSS problem is NP hard and brute force method unable to find the solutions so approximate solutions are found with metaheuristic algorithms. The objective is to find out the scheduling sequence of jobs to minimize total completion time. In order to meet the objective criterion, existing metaheuristic techniques viz. Tabu Search (TS), Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) are implemented for small and large sized problems and effectiveness of these techniques are measured with statistical metric

Yoga Posture Classification using Computer Vision

There has been over the past few years, a very increased popularity for yoga. A lot of literatures have been published that claim yoga to be beneficial in improving the overall lifestyle and health especially in rehabilitation, mental health and more. Considering the fast-paced lives that individuals live, people usually prefer to exercise or work-out from the comfort of their homes and with that a need for an instructor arises. Hence why, we have developed a self-assisted system which can be used to detect and classify yoga asanas, which is discussed in-depth in this paper. Especially now when the pandemic has taken over the world, it is not feasible to attend physical classes or have an instructor over. Using the technology of Computer Vision, a computer-assisted system such as the one discussed, comes in very handy. The technologies such as ml5.js, PoseNet and Neural Networks are made use for the human pose estimation and classification. The proposed system uses the above-mentioned technologies to take in a real-time video input and analyze the pose of an individual, and classifies the poses into yoga asanas. It also displays the name of the yoga asana that is detected along with the confidence score

EXPERIMENTAL INVESTIGATIONS OF A SOLAR PARABOLIC TROUGH COLLECTOR FOR CIRCULAR AND ELLIPTICAL ABSORBER

             Solar parabolic trough collector is one of the most efficient and an effective technology to deal with environmental pollution and it has gained much attention due to the recent energy demand. The solar parabolic trough collector is one of the most promising techniques for absorbing the heat from the sun. This heat is utilized for electricity generation and other industrial heating applications. This paper describes the theoretical and experimental assessment of performance of the circular and elliptical absorbers used in solar parabolic trough collector. The absorber tube of parabolic trough collector is used to transfer the heat to the working fluid. The working fluid considered over here is water which is the best operating medium in direct steam generation. The mass flow rate of water in absorber tube is analyzed in 3 stages as 0.016, 0.024 and 0.030 kg/s respectively. The experimental test is done in Chennai-Tamilnadu, Southern part of India which experiences a superior temperature throughout the year. The experiment is conducted for the period of one year from June 2015 to May 2016. The performance improvement focuses on collector efficiency, useful heat transfer rate, outlet temperature of working fluid, temperature gradient, overall heat transfer rate and the thermal losses

Diversity and present status of croaker fishery along Odisha Coast

Croakers are locally called as “Patharamundi”, “Sila” or “Borei” are commercially important demersal resources exploited all along the Odisha coast. The diversity and status of croaker fishery along Odisha coast in the Bay of Bengal is reported. Landings of croakers showed an increasing trend over the decades with lowest catch recorded in 1976 (333 tonnes) and peaked in 2011 (46,468 tonnes) after which the catch has been declining till 2018. Among the maritime states of India, Odisha, contributing 20,625 tonnes accounting for 18% of the country’s total croaker landings in 2020, showed a tremendous increase compared to the previous year. It was a significant component in the trawl catches forming 34% of the total demersal fish landings and 12% of the total marine fish landings of Odisha. Lesser sciaenids (49%) dominated the croaker landings. They were caught by various gears such as trawl nets, gillnets, hook & line, ringseines, and shoreseines. Bulk of the catches were taken by trawl nets (73%) followed by gillnets (22%). More than 20 species contribute to the fishery of which the major species were “lesser sciaenids” such as Johnius carutta (40%), Pennahia anea (30%), Panna heterolepis (12%), Kathala axillaris (9%), Nibea maculata (5%). Otolithes ruber (66%), Chrysochir aureus (23%), Pterotolithus maculatus (7%) dominated in the “intermediate sciaenids” and Otolithoides pama among the “greater sciaenids” with 98% contribution. Protonibea diacanthus locally called as “Telia” is gaining attention among the fishermen in the recent past due to their high quality swim bladders which are used for the production of isinglass for export. As compared to previous years, the lowest catch was reported in 2020 (0.30 tonnes) probably due to non-fishery causes such as Covid pandemic which affected general fishing activities.However, continuous monitoring and management of this economically important species is required. Juveniles and young adults of several species of croakers in bottom trawls as bycatch can cause an economic loss to the fishery sector and require management measures

Recognition and Classification of Leaf Disease in Potato Plants

Farming is one of the most important lifelines of the country. A nation’s growth majorly depends on how advanced and effective their agricultural practices are in improving the crop yield. When a crop is grown many at times, farmers are unable to identify the health and wellbeing of the plant; they only recognize the problems when it becomes too late hence losing out on that year's expected yield. In this study, we have introduced a recognition and classification technique which is able to detect any ailments that the plant is suffering from at an early stage itself thus enabling the farmers to do the needful at a recoverable stage itself. To make the system as user-friendly as possible, we have provided a feature where the farmers are able to assess the health of the plant by providing a picture of the potato plants’ leaf

Relationship of ethnicity and CD4 Count with glucose metabolism among HIV patients on Highly-Active Antiretroviral Therapy (HAART)

Background HIV patients on HAART are prone to metabolic abnormalities, including insulin resistance, lipodystrophy and diabetes. This study purports to investigate the relationship of ethnicity and CD4+ T cell count attained after stable highly-active antiretroviral treatment (HAART) with glucose metabolism in hyperrtriglyceridemic HIV patients without a history of diabetes. Methods Demographic, anthropometric, clinical, endocrinologic, energy expenditure and metabolic measures were obtained in 199 multiethnic, healthy but hypertriglyceridemic HIV-infected patients [46% Hispanic, 17% African-American, 37% Non-Hispanic White (NHW)] on stable HAART without a history of diabetes. The relationship of glucose and insulin responses to ethnicity, CD4 strata (low (\u3c300/cc) or moderate-to-high (≥ 300/cc)), and their interaction was determined. Results African-Americans had significantly greater impairment of glucose tolerance (P \u3c 0.05) and HbA1c levels (P \u3c .001) than either Hispanics or NHWs. In multivariate models, after adjusting for confounders (age, sex, HIV/HAART duration, smoking, obesity, glucose, insulin and lipids), African-Americans and Hispanics had significantly higher HbA1c and 2-hour glucose levels than NHW’s. Demonstrating a significant interaction between ethnicity and CD4 count (P = 0.023), African Americans with CD4 \u3c300/cc and Hispanics with CD4 ≥300/cc had the most impaired glucose response following oral glucose challenge. Conclusions Among hypertriglyceridemic HIV patients on HAART, African-Americans and Hispanics are at increased risk of developing diabetes. Ethnicity also interacts with CD4+ T cell count attained on stable HAART to affect post-challenge glycemic response
