Experimental Evaluation of a Mobile Wick Solar Still with External Condenser in Rennes, France| Chapter 7 | Scientific Research, New Technologies and Applications Vol. 3

This study assesses the performance of a novel mobile wick solar still with a passive external condenser, designed and manufactured by IPFH2O. The objective of the system is to facilitate the production of potable water from non-potable water sources through the utilisation of solar energy. The system is designed for use in areas where access to drinking water remains a significant challenge. The tests were conducted over a four-day period between October and December 2021 at the University of Rennes 1, which is situated in Brittany, an area characterised by a sub-oceanic climate. The system was monitored manually in accordance with a one-hour interval schedule on the test days. The data collected included measurements of the temperatures of the components, the relative humidity, the global insolation, and the hourly production. This data was then used to calculate the system's energy and exergy yields in order to assess the system's performance. The data collected enables the system's performance to be determined and compared with that of other existing solar installations. In addition, the data allows for the characterisation of the system's operation and the proposal of technical solutions to optimise it. Distilled water production is halted completely when the sun's rays are too weak to rotate the belt, before terminating the acquisition. The obtained data is initially processed and recorded using XFlow software. It is then converted into Excel format for further analysis.

Determination of Acute Toxicity of Metasystox among Freshwater Fish, Nemacheilus botia from Kedrai Dam in Maharashtra, India | Chapter 6 | Advanced Research in Biological Science Vol. 6

This stage primarily focuses on the severe toxicity of Metasystox on the freshwater fish, Nemacheilus botia from Kedrai dam in Maharashtra, India. The indiscriminate use of these pesticides to better agricultural result and yield may have impacts on non-mark organism, particularly aquatic life and atmosphere. On the freshwater fish Nemacheilus botia, the severe toxicity of the organophosphate pesticide Metasystox has happened investigated. For many age, the fish have been used to evaluate the level of water contamination. To decide the median inevitable doses of Metasystox (Oxydemeton-methyl) over 24, 48, 72, and 96 hours, static bioassays were transported on freshwater fish, N. botia. The LC50 values were 10.3, 9.131, 7.884, and 7.018 ppm subsequently 24, 48, 72 and 96 hours respectively. The results show that the LC50 principles decreased accompanying increase in exposure ending. Fish mortality on account of pesticide uncovering mainly depends upon allure sensitivity to the death, its concentration and event of exposure. The judgment of LC50 concentration of contaminants is an important step before completing activity further studies on physiological changes in animals. In the study the N. botia exposed to metasystox, the severe toxicity level was expressed in conditions of LC50 values.

Water and Atmospheric Water Generation | Chapter 4 | Recent Progress in Science and Technology Vol. 5

 This work depicts the success, importance, and impediments to achieving valuable results on the miscellaneous ways to capture environmental water to lessen the actual worldwide stress. Contemporary culture demands innovative land, civil, industrial, country, and defense activities, that causes the depletion of most common raw materials, including freshwater. Atmospheric water dynamo (AWGs) could become a complementary resource to reduce freshwater stresses. The plainest AWGs do not require capacity; they collect fog and dew. Fog connoisseurs operate in the specific positions where fogs are coarse; the ones made with recently developed materials have five periods higher yields than the usual ones. Dew collectors are two types: passive and active. Passive AWGs are plain tilde surfaces that work based on the variation of the never-ending humidity and hotnesses; they have one cycle accompanying low yields compared to the fog connoisseurs. Their output increases by utilizing newly developed matters inspired by nature. Combining descants and hygroscopic matters with absorbent gel and thermal-impressionable polymers resulted in multi-cycle assimilation-desorption experimental devices that converted the field. Active AWGs have a complex structure and demand mechanical and electrical force to work. The AWGs efficiency depends on the materials secondhand, the environmental humidness and temperature, and the condenser operating temperature.
