Abstract—Solar water heating is a thermodynamic process of heating water using sunlight with the help of solar water heater. Thus, solar water heater is a device used to harness solar energy. In this paper, a modified solar water heating system (MSWHS) has been proposed over flat plate collector (FPC) and Evacuated tube collector (ETC). The modifications include selection of materials other tha...
In the present work the ground temperature has been validated for climatic condition of Sriperumbudur near Chennai, India to evaluate thermal conductivity and diffusivity of the soil. For the evaluated thermal conductivity of the soil, an EAHE has been designed for a given dimension of room with optimized values of number of air changes, length of pipe, radius of pipe and depth at which heat ex...
Phytoplankton-bacteria interactions drive the surface ocean sulfur cycle and local climatic processes through the production and exchange of a key compound: dimethylsulfoniopropionate (DMSP). Despite their large-scale implications, these interactions remain unquantified at the cellular-scale. Here we use secondary-ion mass spectrometry to provide the first visualization of DMSP at sub-cellular ...
An analytical investigation has been conducted on the performance of an adsorption chiller driven by solar collector panel for the climatic condition of Dhaka. A set of mathematical model and simulation technique are exploited to investigate the system performances of solar driven basic adsorption chiller with silica gel-water as adsorbent/adsorbate pair. For base run condition, at least 13 col...
Oregon’s strawberry industry has more than a century history. Unfortunately, strawberry production has been declining drastically in the last two half decades due to declining price, rising cost of production and competition from California, Florida, Mexico and China. Most of Oregon’s strawberries were for processing markets. The combination of warm, dry days with cool nights optimizes color an...
Many studies have reported statistically significant associations between bird migratory phenology and climatic variables, and, consequently, it is mostly accepted that recent shifts in migration dates are a reaction to present climate change. Impacts of weather and climate on departure date, progression and stopover frequency and duration have been reviewed in order to explain the current know...
Rural housing is an important issue in Iran due to the large number of villages, their geographical dispersion, the fragile rural economy, and the crucial role of rural development in sustainable development. Considering these subjects, policies regarding rural housing development and its quality improvement are to be deduced, which results in rural housing typologies template in different clim...
The major reasons for environmental contamination are population explosion, increase in industrial and other urban activities. One of the consequent effect of these activities is heavy metal pollution. It is one of the serious issue to be discussed by the scientists and academicians that how to solve this problem to protect the environment. As heavy metals are non-biodegradable so they require ...
In this paper, an approach to assessing ecological suitability of crop growth was developed using GIS, through a case study of maize planting in Jilin Province, in the northeast China, in order to improve the accuracy and objectivity of the evaluation, promote the rationality of crop distribution, and increase the efficiency of the agro-resource utility. Climate and soil conditions in the regio...
The Colorado River system exhibits the characteristics of a heavily over-allocated or 'closing water system'. In such systems, development of mechanisms to allow resource users to acknowledge interdependence and to engage in negotiations and agreements becomes necessary. Recently, after a decade of deliberations and environmental assessments, the Glen Canyon Dam Adaptive Management Program (GCD...
