Predicted and Measured Drainable Porosities for Field Soils

Experiments were conducted on large field cores to determine the relationship between drainage volume and water table depth for five soils. The measured drainage volumes were less than predicted from the soil water characteristics for three soils, but were in good agreement for the other two. Drainable porosities were calculated from both theoretical and experimental drainage volume-water table depth relationships by assuming that the unsaturated zone is essentially \u27drained to equilibrium, with the water table. The experimental drainable porosities thus obtained were less than predicted. Drainable porosities for drainage in two-dimensions were calculated from experimental results for one-dimension by assuming an elliptical water table profile. These results gave nearly constant drainable porosities for the layered soils and a variable drain-able porosity for Wagram, a homogeneous, sandy soil

Analysis of Labour Productivity in Construction Sector around Mumbai region

Productivity is an important aspect of construction industry that may be used as an index for efficiency of production. Efficient management of construction resources can lead to higher productivity which can help to achieve cost and time saving. Construction is labour oriented industry. It heavily relies on the skills of its workforce. The labour is industry’s most valuable asset. It is important to improve efficiency of production by improving productivity of labour. Aim of this paper is to give the data collection for calculation of labour productivity. The data have been collected by using time study technique in Mumbai region. Method study for placing and binding the reinforcement of column has been done previously. Applying the changes in method the data have been again collected and analysis for productivity have done which results in saving of project time, labour cost with maintaining quality of work

Knowledge, attitude and practices towards COVID-19 among people living with HIV in Pune, India: a cross-sectional study

Background: Studies on knowledge, attitude, and practices (KAP) are important for implementation of interventions. This cross-sectional study was conducted among HIV infected individuals attending antiretroviral therapy (ART) centre at Pune, India, to assess KAP towards COVID-19.Methods: The study conducted between June and December 2020 consisted of twelve, five and seven questions pertaining to knowledge, attitude, and practices respectively towards COVID-19. Frequencies and percentages of correct knowledge, attitude and practices were calculated. Overall knowledge scores were categorized into poor, moderate and good using class width equation.Results: Of the total 1175 participants enrolled, 649 (55.2%) were females. Mean age and CD4count of participants at study entry were 44 years (SD: 9.1) and 637 cells/mm3 (SD: 297) respectively. Overall, 400 (34.0%, 95% CI: 31.33-36.83), 612 (52.1%, 95% CI: 49.18-54.98) and 163 (13.9%, 95% CI: 11.95-15.98) participants had good, moderate and poor knowledge respectively regarding COVID-19. Illiterate participants had six times higher probability of having poor knowledge as compared to their counterparts (OR 5.70, 95% CI: 3.94-8.23; p<0.001). Majority of people living with (PLHIV) had correct attitude towards adherence to government prevention and control measures. Healthy preventive practices of social distancing (99.5%), wearing masks at public places (99.7%) and frequent washing hands with soap and water (98.7%) were followed by PLHIV.Conclusions: PLHIV have average knowledge, correct attitude towards adherence to government prevention and control measures, and appropriate practices towards prevention of COVID-19. Counselling sessions at ART centres should include information for improving knowledge related to COVID-19 especially targeting illiterate individuals.

Product Development from Apple, Grapes and Berries Food Waste: Market Research, Industry Analysis and Opportunity Assessment

This study focuses on the apples, berries, and grapes wastage produced by the population of North America and Europe. The research is aims to conduct in-depth comparison between these two regions based on volume and monetary value of fruit waste produced. The research was conducted by an inquiry based primary research with industry experts product development scientist and good waste management companies, and secondary research was conducted by collecting information from company’s websites, annual reports, white papers, and financial reports. This research open the reusability opportunity of fruit waste, optimize the food processing and manufacturing industry. The waste from apples, berries, and grapes are high in moisture and biologically active components (BACs) which make them ideal raw materials for the functional food product industry. The market research conducted in the study highlights the potential in the waste produced by apples, berries, and grapes during food processing and manufacturing through ingredient analysis and comparing it to the functional food ingredient requirements. The results of the market research and industry analysis will assist industries and researchers in finding and optimizing processes to reduce waste and maximize the extraction of fruits’ nutrients content.
