Biotransformation of bovine tannery fleshing into utilizable product with multifunctionalities
Leather industries aim at the transformation of putrescible animal raw hides and skins into a stable non-putrescible material (leather), ultimately resulting in solid wastes generation. Storage of limed bovine fleshing, a predominant proteinaceous solid waste material from pre-tanning processes is highly discouraged due to their putrescible nature. Diversely, bio-conversion of solid waste into a saleable product could be achieved by bacterial fermentation process. Lactic acid (LA) fermentation with Delimed Bovine Tannery Fleshing (DBTF) by Lactobacillus plantarum was experimented; incubation time, tapioca flour and lactose were the three prime independent variables studied. Maximum LA production in steam cooked DBTF medium was achieved with pH 6; inoculum 12.5% (v/w); lactose 8.81% (w/w) and tapioca flour 8.9% (w/w) at 96 hours of fermentation. Initial yield of about 4.56 g/L of LA (p <.05), upon statistical manipulation of the medium composition marked up to 12.36 g/L, enabling 2.7-fold increase in the LA production with DBTF as a relatively cut-rate substrate. Fermentation resulted in Fermented Fleshing Flour (FFF) with marked protein level of 76.32% and lower fibre content. Formation of protein hydrolysates and new acid groups in FFF were authenticated via Field Emission Scanning Electron Microscopic (FE-SEM) and Fourier Transform Infra-red Spectroscopic (FTIR) analyses respectively. In situ acid (LA) generation and formation of protein hydrolysates/free amino acids during LA fermentation points to the antibacterial (against Gram-negative bacteria, followed by Gram-positive bacteria) and invitro antioxidative properties with dose dependency, of FFF, favouring its possible utilization in aqua feed industries as a superior grade proteinaceous feed ingredient with inbuilt bio-functionalities.. 2020 Informa UK Limited, trading as Taylor & Francis Group. -
Valorization of bovine tannery fleshing waste as a fish meal replacer: a conceivable green approach
The study intended to utilize bovine tannery fleshing (BTF) a significant contributor of solid wastes in leather industries, in its unhydrolyzed form (raw fleshing flour [RFF]) as well as in fermented form (fermented fleshing flour [FFF]) as fish meal (FM) replacer in formulated aqua feeds. In line with this, experimental diets were formulated, characterized, and evaluated for their virtue. Improvement in the physical quality of diets was achieved with FFF incorporation, enabling better pelletability, palatability, and feed texture. As the formulated diets were of sinking type, feeding trials on column as well as bottom feeders were concertedly attempted, as a value-added application of proteinaceous feed ingredient (BTF) in aquaculture sector. FFF inclusion diets proved superior to RFF inclusion diets. Maximum protein and lipid retentions of 89% and 92% were evidenced. Fish feeding experiments disclosed the productive impact of substituting FM with FFF by 50 and 75% on the performance (fish growth) of Cirrhinus mrigala (19.03 cm final length, 112.89 g Kg-1 final body weight, and 99% survival rate) and Labeo rohita (22.19 cm final length, 214.99 g Kg-1 final body weight, and 97% survival rate) respectively, with enhanced muscle biochemical compositions. FFF inclusion diets best suited column feeders than bottom feeders, with acceptable feed conversion ratio (< 2) and about 65% and 69% of protein in Rohu and Mrigal, respectively after 90 days of feeding. Absence of feed related mortality and multimycotoxins in FFF inclusion diets authenticated its invulnerable nature, signifying the need of bacterial fermentation processes to pull out the maximum worth of the solid waste. Thus, bovine tannery fleshing (BTF) would probably be used as a relatively inexpensive, effectual, safe, and an absolute source of protein for marine animals, reinforcing aquaculture business to strengthen up its profitability and eventually; this is an assuring conscientious solid waste management strategy that could be scaled-up to develop high-quality aquaculture feeds. 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. -
Perceived Discrimination and Happiness Among Tribal Unmarried Mothers
The present study aimed to understand the relationship between perceived discrimination and happiness among tribal unmarried mothers. The sample included 30 tribal unmarried mothers from the Wayanad district in Kerala, India. Data were collected using a socio-demographic response sheet, Oxford happiness questionnaire (Short form), and everyday discrimination scale. MannWhitney U test showed that tribal unmarried mothers did not differ in happiness concerning their income, education, putative father from the same tribe or not, and living status. Compared to those with higher income, mothers with lower income were higher in perceived discrimination. Correlation analysis revealed a negative relationship between perceived discrimination and happiness. Regression analysis confirmed that perceived discrimination is a negative predictor of happiness. 2022, The Author(s) under exclusive licence to National Academy of Psychology (NAOP) India. -
An Intelligent Decision Support System to Aid Profit Planning in Manufacturing Companies
In order to assure accuracy in profit planning and decision-making, this study uses an intelligent decision support system to investigate an appropriate approach for calculating the "Break-Even" point in multi-product segments while taking into account the implications for contribution margin, demand, and capacity. The research's methodology and findings may be used to propose new projects, grow businesses, and make decisions in processes that focus on many products. Data are used to illustrate the advanced level of break-even analysis and application, and a description of the convenient and system-generated method of computation is given. A mathematical approach has been used based on actual data to show how to determine the break-even point without sacrificing the influencing aspects such as contribution margin, capacity, product mix, and demand for each. The researchers have created a good system application-oriented platform to make it simple to calculate the break-even point, which will be crucial for decision-making and profit planning even with more than 500 SKU (Stock Keeping Unit). This research evaluated the data and created formulas for actual data structure-based analysis. The study's conclusions have a significant influence on those companies that need to determine the true break-even threshold. The challenge area of concern might be the applicability of this activity for other sectors and other countries as this research was centred on the plastic bag industry in Malaysia. Future research can also analyse other important factors like start-up and semi-variable costs as they are not included in the current study. The identified break-even threshold can still be used effectively given the current market demand and the product's capacity. 2023, Ismail Saritas. All rights reserved. -
Influence of Mindfulness on Game Addiction-Mediating Role of Emotional Control
In the past few decades, online games have become immensely popular among the younger generation thus leading to online game addiction. Previous researches acknowledge that mindfulness or present-focused awareness may reduce addiction. Moreover, addiction is found to have an impact on the propensity to respond to the situations in the environment in a way that is acceptable to all the people (emotional control). The present study attempts to study the influence of mindfulness and emotional control on game addiction. For this, 187 college students were selected through the Simple Random Sampling method. Personal Profile Sheet, The Online Game Addiction Scale, Mindful Attention Awareness Scale (MAAS) and The Emotional Control Questionnaire, with four dimensions of Rehearsal, Emotional Inhibition, Aggression Control and Benign control were used to collect the data. The study found a significant gender difference in the level of game addiction where boys being more addicted to online games than girls. Mindfulness shows a significant negative influence over Game Addiction. Among the four dimensions of emotional control, the two dimensions viz., rehearsal and benign control show mediation effect between mindfulness and game addiction. However, the mediating role of emotional inhibition and aggression control was not significantly demonstrative. The Author(s) 2024. -
AGGRESSION AS A PREDICTOR OF GENERAL WELL-BEING AMONG PUBLIC HEALTH WORKERS
Social atrocities and discrimination make sanitary workers vulnerable to aggression which in turn disrupts their well-being. The issues concerning the psychological health of sanitary workers have been addressed less by researchers. The present study aimed to assess the level of aggression and general well-being among sanitary workers. An aggression questionnaire, consisting of four dimensions, namely physical aggression, verbal aggression, anger and hostility was used. The PGI general well-being measure and personal profile sheet consisting of socio-demographic details was given to 150 sanitary workers who were selected through purposive sampling method. The dimensions of aggression- anger and hostility were negatively correlated with the general well-being of the participants. Amongst the four dimensions of aggression, anger is found to be the predictor of general well-being. 2022 Australasian College of Health Service Management. All right reserved. -
Gender as a Predictor in the Perception of Sexual Harassment Definition
Sexual harassment is a pervasive problem across the globe and it is generally viewed subjectively. The review of the literature suggests that individual perception, history of past sexual harassment and other personal factors influence beliefs concerning the seriousness of the problem. The present study aims to explore the role of socio demographic variables in the definition of sexual harassment. One hundred and sixty-one college students volunteered for this study. Personal profile sheet and Sexual Harassment Definition Questionnaire were used to collect the data. The results of the chi-square test suggested that girls and students who already experienced sexual harassment found larger social incidents as harassment. However, the results of logistic regression found gender as a strong predictor of sexual harassment definition and the history of past harassment was failed to provide a statistical significance. Educating men on male privilege, violence against women and identifying behaviours in them that are not acceptable by women will be helpful. The Electrochemical Society -
Machine learning approach for automatic solar panel direction by using nae bayes algorithm
The upsurge in fuel prices are pointing out the fact that, the deficiency of conventional form of natural resources and building dams can never fulfill the demand of the growing population and it is exponentially increasing the electricity demand. Electricity is a day-to-day component, which is utilized for lighting, running appliances, machines. Moreover a large number of people are now switching to electric cars. Henceforth, it is equally important to achieve self-sustainability in energy needs and also it is necessary to have an infinite energy source. Sustainable power is the solitary solution to resolve this issue. On the other hand, the Indian government is promoting solar technology a lot in the year 2021 by providing subsidies to a maximum limit of 65% for the installation of home solar projects and this encourages people to switch to electric vehicles to reduce the pollution. This article presents a machine learning based dual-axis solar tracker to enhance the energy harnessing efficiency. Furthermore, the proposed method utilizes Nae Bayes algorithm to develop a better solution for producing higher energy from the solar panel. The Nae Bayes algorithm is a type of machine learning algorithm, which has been used to predict the reliable direction. This proposed method generates higher electricity, when compared with the traditional method. The experimental results aim to fix the north east direction of solar panel that produces 17.4 watts per hour, wherein the proposed method produces 24.8 watts. It is indicated that, more than 25% additional power generation is obtained by using Nae Bayes algorithm method. 2021 IEEE. -
Enhancement of thermoelectric efficiency in vapor deposited Sb 2Te3 and Sb1.8In0.2Te3 crystals
Pure and indium doped antimony telluride (Sb2Te3) crystals find applications in high performance room temperature thermoelectric devices. Owing to the meagre physical properties exhibited on the cleavage faces of melt grown samples, an attempt was made to explore the thermoelectric parameters of p-type crystals grown by the physical vapor deposition (PVD) method. The crystal structure of the grown platelets (9 mm8 mm2 mm) was identified as rhombohedral by x-ray powder diffraction method. The energy dispersive analysis confirmed the elemental composition of the crystals. The electron microscopic and scanning probe image studies revealed that the crystals were grown by layer growth mechanism with low surface roughness. At room temperature (300 K), the values of Seebeck coefficient S (c) and power factor were observed to be higher for Sb1.8In0.2Te 3 crystals (155 ?VK-1, 2.669 10-3 W/mK2) than those of pure ones. Upon doping, the thermal conductivity ? (c) was decreased by 37.14% and thus thermoelectric efficiency was improved. The increased figure of merit, Z = 1.23 10-3 K -1 for vapour grown Sb1.8In0.2Te3 platelets indicates that it could be used as a potential thermoelectric candidate. Pure and indium doped antimony telluride (Sb2Te 3) crystals were grown by the physical vapor deposition (PVD) method. Incorporation of indium atoms into the antimony sub lattice improved Seebeck coefficient and reduced thermal conductivity. The increased figure of merit, Z = 1.23 10-3K-1 for vapor grown Sb 1.8In0.2Te3 platelets indicates that it could be used as a potential thermoelectric candidate. 2014 WILEY-VCH Verlag GmbH & Co.

Studies on sulfur doping and figure of merit in vapor grown Sb2Te3 platelet crystals
A series of p-type Sb2Te3-xSx(x=0, 0.1, 0.2, 0.3 and 0.4) samples for each sulfur composition was vapor deposited to explore the crystal growth mechanism of platelet morphology and to understand their potential use for thermoelectric devices. Structural characterization performed by X-ray diffraction exhibited consistent rhombohedral unit cell parameters for all the antimony telluride crystals with D3d5 space group symmetry. Scanning electron microscopy (SEM) and energy dispersive analysis by X-rays (EDAX) were employed for morphological and compositional studies. The Seebeck coefficient S (?c) of Sb2Te3-xSx crystals for sulfur composition, x=0.3 was remarkably improved, yielding a figure of merit (ZT)=0.54, which is ?2.5 fold rise compared to the melt grown Sb2Te3 crystals. The atomic force microscopic (AFM) imprints revealed that, with increasing content of dopant, distribution of etch pits and microhardness increased in sulfur doped crystals. By optimizing sulfur doping, the antisite (AS) defect formation can be suppressed for enhancing ZT and the results obtained enable to design novel thermoelectric materials for application in power generation and refrigeration. 2015 Elsevier B.V.
