A field experiment on the seasonal incidence of stem fly, Melanagromyza sojae (Zehntner) infesting black gram was carried out in variety GU 1 (Gujarat Urd 1) during kharif 2017 and 2021 at Entomology farm, B. A. College Agriculture, AAU, Anand. Infestation M. sojaewas observed from 1st WAS i.e., 34th SMW. Later on, infestation increased gradually its highest 39th SMW 68.33 73.33% kharif, 2021, ...

Living in a habitat with comfort is requested by all. Cinder block bricks have poor thermal properties, leading people to use fan heaters and air conditioners regain comfort. To overcome this problem of discomfort buildings, we used lightweight concrete such as foamed which material that has improved properties for In addition, was compared local materials the construction buildings BTC, adobe ...

This paper investigates the sizing and costing methodology for a stand-alone photovoltaic (SAPV) power system based on the number of sunshine hours available in the world. The sizing and costing of the PV system for the electrical load of 3.65 kWh/day was presented in this paper for different continents of the world. The unit cost of electricity generated from the PV system was determined based...

This paper discusses a procedure that was adopted for the development of a linear regression model for estimating solar radiation on horizontal surfaces for 7 Colombian zones. The correlations, the simulated global solar radiation on tilted surface and the simulated diffuse solar radiation on a horizontal surface for each zone are shown. The values of sunshine-hours and the solar radiation were...

Scabies is a common infectious disease and can cause severe outbreaks if not controlled quickly. Besides personal contact history, environmental factors are also important. This study analyzed the effects of environmental climate factors on the incidence of scabies in Taiwan. We conducted a 14-year nationwide population-based study: a total of 14,883 patients with scabies infestation were enrol...

This study analyzes the irrigation water requirement of wheat in Beijing-Tianjin-Hebei region under changes meteorological factors conditions, using growth period data, and data from 197 stations, 1960 to 2019. The results show that: (1) annual average precipitation, wind speed, relative humidity a downward variation trend, while temperature shows an upward trend. Moreover, radiation exhibit ne...

An individual's identification of his retirement situation does not necessarily coincide with the retirement concept as defined by objective measures. Self-evaluation of retirement status by respondents to the Retirement History Study has been analyzed to discover to what extent their subjective assessment of retirement matched the situation predicted by objective measures. For those completely...

A significant amount of economic activity takes place within the home. Unfortunately, it is difficult to assess the cyclical properties of home production because the available data are too sporadic. Using a Real Business Cycle model, we construct quarterly data on three variables that are unobservable at a quarterly frequency: hours worked in the home sector, hours spent in leisure, and the co...

Solar diffuse radiation data including global radiation, shortwave and longwave balances, net radiation and sunshine hours have been extensively analyzed to study the variation of diffuse radiation with turbidity and cloud discharges appearing in the form of atmospherics over the tropics. Results of surface radiation measurements at Calcutta, Poona, Delhi and Madras are presented together with ...
