Waste cooking oil into sustainable and lucrative bio-diesels and their blend with diesel

The necessity to find an alternate fuel has arisen due to the rapid spike in cost of crude oil. In terms of economics, the alternative fuel should be more appealing than fossil fuels. Vegetable oils are used to make costly yet environmentally beneficial biodiesels. Utilizing leftover cooking oil to produce biodiesel is less expensive than using virgin oil. The bio-diesel have prepared from Waste cooking oil (WCO), collected from GITAM University hostel mess. This reaction has accelerated by the base catalysed the transesterification reaction with using ethanol. 1HNMR and IR spectrum analyses were used to describe the biodiesel that was produced. Numerous physico-chemical characteristics of biodiesels and their mixes with petroleum diesel were examined. The results of the investigation indicate that the blends from B10 to B40 have high flash points, lower pour points, and kinematic viscosity in the range of 2 to 5 cSt at 40 oC.

This study presents a long-term performance analysis of a one-mega-watt power grid-connected PV plant installed on the rooftop of GITAM University,Visakhapatnam,Andhra Pradesh, India for 3 years. The 1000 kWp PV plant design, performance analysis, economic feasibility, and greenhouse gas reduction are provided. For 3 consecutive years (2018-2019, 2019-2020 and 2020-2021), the energy yields, performance ratio (PR), capacity utilisation factor (CUF) and efficiency are evaluated. The plant was established in 2018 with a peak power of 1000 kWp. The system feeds the state grid with all of the electricity it produces. The system is continuously monitored and analysed using yield, efficiency and performance parameters for 36 months (September 2018 to August 2021). Solar irradiation data has been collected from the National Renewable Energy Laboratory (NREL) database for these years. The system comprises 3078 PV modules, 23 inverters rating 20 kW/50 kW, a data logger and a Net-metering unit. The annual energy generation of the PV plant recorded during the study period is 1376.29 MWh, 1265.541 MWh and 1115.73 MWh. The annual average performance ratio for the first three consecutive years is observed as 0.68, 0.62 and 0.58, whereas the yearly average capacity factors are 15.5%, 14.11% and 12.72%, respectively. The overall system efficiency of the PV system during the study period is 11.39%. Compared to the country's current conventional thermal power plants, we predict that rooftop PV systems may reduce CO2 emissions by 2145.406 tCO2eq for the base year, based on the electricity produced by this PV plant. The grid-integrated photovoltaic plant in this study is compared to other systems in the literature for performance assessment.

Analyzing the Reading Habits of Medical Students: Insights from a Research Study

modern saying is, "The chapter you are learning today will save someone's life tomorrow. Pay attention." Acquiring knowledge through reading is crucial for the learning process of a medical professional. "A doctor is a student until he dies; once he considers himself not a student anymore, the doctor inside him dies" It can form part of an individual and become a habit, which, once developed, becomes very difficult to break. Reading habit is an essential life skills. Reading in clinical practice is necessary as it is related to clinical competencies. This study investigates the reading habits of medical students at GITAM Institute of Medical Sciences and Research, GITAM University, Visakhapatnam. One hundred students participated in the study through an online questionnaire. All 100 students responded that work most often is engaging with their reading and studying. This study assesses knowledge, attitude, and practice of reading habits among medical students at GITAM Institute of Medical Sciences and Research at Visakhapatnam.

Advances in Animal Models and Cutting-Edge Research in Alternatives: Proceedings of the Third International Conference on 3Rs Research and Progress, Vishakhapatnam, 2022.

Animal experimentation has been integral to drug discovery and development and safety assessment for many years, since it provides insights into the mechanisms of drug efficacy and toxicity (e.g. pharmacology, pharmacokinetics and pharmacodynamics). However, due to species differences in physiology, metabolism and sensitivity to drugs, the animal models can often fail to replicate the effects of drugs and chemicals in human patients, workers and consumers. Researchers across the globe are increasingly applying the Three Rs principles by employing innovative methods in research and testing. The Three Rs concept focuses on: the replacement of animal models (e.g. with in vitro and in silico models or human studies), on the reduction of the number of animals required to achieve research objectives, and on the refinement of existing experimental practices (e.g. eliminating distress and enhancing animal wellbeing). For the last two years, Oncoseek Bio-Acasta Health, a 3-D cell culture-based cutting-edge translational biotechnology company, has organised an annual International Conference on 3Rs Research and Progress. This series of global conferences aims to bring together researchers with diverse expertise and interests, and provides a platform where they can share and discuss their research to promote practices according to the Three Rs principles. In November 2022, the 3rd international conference, Advances in Animal Models and Cutting-Edge Research in Alternatives, took place at the GITAM University in Vishakhapatnam (AP, India) in a hybrid format (i.e. online and in-person). These conference proceedings provide details of the presentations, which were categorised under five different topic sessions. It also describes a special interactive session on in silico strategies for preclinical research in oncology, which was held at the end of the first day.

Study on the qualitative assessment of in-vessel food waste compost by indexing method

The consumption of different food-based goods produces a considerable amount of waste that needs to be conserved in an eco-friendly manner. A study was carried out on food waste compost made from the in-vessel compost process for use in agriculture and its marketability for its fertility and contamination potential. Food waste samples were collected from the canteen and hostels of GITAM University, Visakhapatnam (Andhra Pradesh), India and were transferred to a 125Kg in-vessel food waste composter (Molten Mind F125) and allowed to digest for 24 hrs followed by curing for seven days. After curing, the samples were characterized for nutrient content for fertility index (FI) and heavy metal contamination for clean index (CI). The compost quality index was derived from FI and CI to assess its suitability for agriculture. The pH of the food waste compost sample was reported as 8.4 and the C/N ratio was 28, which was higher than the standard ratio (15-20). The other physicochemical characteristics were analyzed using the standard methods and the concentration of metals was analyzed using Inductively Coupled Plasma Mass Spectrometry ( ICPMS). From the analysis, it was evident that heavy metal concentrations were well within the permissible limits. Further, the compost was characterized to know the fertility index (FI) and contamination index (CI) and its suitability to the soil. FI value was reported as more than 3.1 and CI value more than 4, which indicated that compost was best in quality, having high-value potential and low heavy-metal content, which will be suitable for high-value crops such as organic farming.

Production and characterization of biodegradable polymer-polyhydroxybutyrate from agricultural waste-sugarcane bagasse by the novel marine bacterium Klebsiella pneumoniae G1

An unusual halotolerant Klebsiella pneumoniae G1 producing green biodegradable polymer polyhydroxybutyrate (PHB) was isolated from the soil samples of marine fields near GITAM University, Visakhapatnam. The strain grew at wide salinities (2–10 %) and pH ranges (5–10), hence called halo-acid-alkali-tolerant. The time course with the optimized parameters (glucose as carbon source) yielded 6.86 g/L of PHB. G1 was tested further for PHB production on sugarcane bagasse (SCB, 5 %) which displayed PHB production of 9 g/L (a 3.6-fold increase). Structural assessment studies (FTIR, NMR, DSC, and TGA) confirmed the presence of PHB. This is the first report of producing high titers of PHB by G1 using SCB. The strain is advantageous to upscale the PHB production using SCB wastes for valorization.

Engine Performance and Emission Characteristics of Four-Stroke Single Cylinder Diesel Engine by Using Rice Bran Oil as Fuel

This project is presented in context of research project at GITAM University to understand and improve the performance of Diesel engine by using different Blends. Biodiesel was distinguished as a potential option to petrodiesel fuel since it has fuel properties as diesel. Utilization of consumable oils in biodiesel will creates foundations at raise of costs, yet couple of edible oils, for example rice bran oil have prohibitive heating conditions when contrasted with non-edible oil are accessible in a few nations such as soybean oil in USA. Inside this job, the performance examination of single chamber, 4-stroke, and water-cooled diesel engine was done utilizing rice bran oil methyl ester as biodiesel contrasting option to diesel fuel. Trial tests have been directed with scope of engine loads utilizing rice bran oil methyl ester (RBOME) and its diesel mixes with biodiesel in the proportion of B10, B20, B30 and B0 i.e., petrodiesel 100% by volume. In this exploration work, brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), brake specific energy consumption (BSEC) and exhaust gas temperature (EGT) are considered as engine execution attributes. The examination revealed that B20 mix of biodiesel has similar brake thermal efficiency as diesel. B20 has most minimal and has most astounding BSFC, BSEC after all the biodiesel mixes. B20R has shown practically identical execution as diesel and it can be considered as other option to diesel fuel.

Analyzing student web browsing behavior is a challenging task. This paper mainly focuses on a methodology to identify the influencing factor that has driven a student towards navigating a particular web site. Most of the research in this direction is untouched to estimate the influence of faculty on the student’s behavioral patterns. In this work we focus on a novel statistical approach based on adaptive Gaussian mixture model, where the data clustered is given as input to the model to classify the student navigating pattern. The concept of regression analysis is used to find the relationship between student’s navigational behavior and faculty’s experience and rating. This article considers a real time dataset of GITAM University for experimentation.

WIND DAMAGE TO TREES IN THE GITAM UNIVERSITY CAMPUS AT VISAKHAPATNAM BY CYCLONE HUDHUD

Over the past thirty three years Gandhi Institute of Technology and Management (Gitam University) has evolved into a world class university. The introduction of many exotic and indigenous species of trees and shrubs has transformed the campus into a green oasis. Cyclone Hudhud with wind speeds gusting from 175 to 200 kmph caused massive destruction to the green cover of the campus. Many trees were either uprooted or were severely damaged. A visual assessment of the damage incurred by the trees in the Gitam University campus has been carried out by the author to understand the different ways in which trees respond to cyclonic winds. The results of the study would help in minimizing the damage to trees from future storms.

Prevalence of health behaviors and their associated factors among a sample of university students in India

With advances in knowledge about health promotion, public health professionals are in search for the determinants of personal health behaviors. The purpose of this study was to assess the prevalence of health behaviors and its associated factors in a sample of Indian university students. Using a cross-sectional survey, we assessed health behavior among a sample of randomly selected university students. The sample included 800 university students from non-health (mainly engineering and sciences) undergraduate courses of Gitam University, Visakhapatnam in India. The students were 541 (67.6%) males and 259 (32.4%) females in the age range of 17-20 years (Median age=18.2 years, SD=1.0). On average, students engaged in 15.8 out of 25 health behavior practices. There was a high rate of overweight and obesity (26.8% and 10.7%, respectively), low rate of brushing teeth at least twice a day (28.6%), annual dental check-up (25.8%), habitual seatbelt use (23%), and poor dietary patterns (79% ate less than the recommended fruit and vegetable consumption of five servings a day, and 68.5% did not avoid eating fat and cholesterol). In multivariate analysis among men, personal constraints (Odds Ratio=OR 1.75, Confidence Interval=CI 1.09-2.82), health benefits (OR=2.01, CI=1.27-3.17), and not suffering from depression (OR=0.60, CI=0.22-0.94) were associated with the health behavior index. Among women, those who were living away from their parents or guardians (OR=1.94, CI=1.06-3.55), economically better off (OR=2.16, CI=1.00-4.63), and had higher social support (OR=3.65, CI=1.75-7.63), were associated with the health behavior index. Students had a high proportion of health behavior practices. Several high health risk practices were identified, including overweight, poor dental practices, poor dietary and sleeping habits. It is hoped that the gender-specific predictors identified, including sociodemographics as well as social and mental health variables, can also be utilized in designing health promotion programs.

Prevalence of overweight/obesity and central obesity and its associated factors among a sample of university students in India

Obesity and the lifestyle characteristic of Indian society lead young people to conditions of potential cardiovascular risk. The purpose of this study was to assess the prevalence of overweight/obesity and central obesity and its associated factors in a sample of Indian university students. In a cross-sectional survey assessed anthropometric measurements and a self-administered questionnaire among a sample of randomly selected university students. The sample included 800 university students from non health (mainly sciences) courses Gitam University in India. The students were 541 (67.6%) males and 259 (32.4%) females in the age range of 17-20 years (M age 18.2 years, SD=1.0). 37.5% were overweight or obese, 26.8% overweight (≥23-27.4 BMI) and 10.7% obese (≥27.5 kg/m(2)), 11.7% underweight (<18.5 kg/m(2)) and 16.4% central obesity (WC ≥90 cm for men and ≥80 cm for women). In multivariate analysis among men lack of non-organised religious activity (odds ratio=OR 0.85, confidence interval=CI 0.77-0.95), lower dietary risk knowledge (OR=0.64, CI=0.41-0.99), tobacco use (OR=2.23, CI=1.14-4.38), and suffering from depression (OR=1.59, CI=1.00-2.47) were associated with overweight/obesity, and younger age (OR=0.32, CI=0.12-0.90), lives away from parents or guardians (OR=1.79, CI=1.04-3.07), healthy dietary practices (OR=1.95, CI=1.02-3.72) and 9 or more hours sleep duration (OR=0.28, CI=0.09-0.96) were associated with central obesity. In bivariate analysis among women, lack of social support, lower dietary risk knowledge, tobacco use, and 9 or more hours sleep duration were associated with overweight/obesity and lives away from parents or guardians and abstinence from alcohol associated with central obesity. The study found a high prevalence of overweight/obesity and central obesity. Several gender specific health risk practices were identified including lack of dietary risk knowledge, shorter sleep duration, living away from parents or guardians, tobacco use and lack of social support and religiousness that can be utilised in health promotion programmes.

Subjective happiness and health behavior among a sample of university students in India

The aim in this study was to establish the associations between health behaviors and happiness in an Asian (Indian) population. In a cross-sectional survey we assessed happiness and health behavior among a sample of 800 randomly selected university students taking nonhealth (mainly engineering and sciences) undergraduate courses at Gitam University, Visakhapatnam in India. The students were 541 (67.6%) males and 259 (32.4%) females in the age range of 17 to 20 years (M age 18.2 years, SD = 1.0). We performed multivariate analysis and found that better social support, better personal mastery, normal sleep duration, no current tobacco use, and eating breakfast daily or almost daily were associated with happiness. The findings partially confirmed the association between happiness and several health behaviors mediated by social factors. Our findings can be utilized in programs designed to improve overall well-being of university students in India.
