Slope and pig slurry rate may increase the transfer of chemical elements by surface water runoff
AbstractThere is a need to evaluate the interference of pig slurry rate and the terrain slope in the chemical elements losses from the soil. This work aimed to quantify water and chemical element losses by surface runoff due to terrain slope and pig slurry rate (PS) in two soils with contrasting textures. Two trials were evaluated in 2018 and 2019 in Cambisol and Nitisol. Rates of 0, 22.5, 45, and 90 m3 ha−1 yr−1 of PS were applied superficially in sites with slopes ranging from 10% to 35%. Perennial forage grass Tifton 85 (Cynodon dactylon) was grown as summer crop and ryegrass (Lolium multiflorum) was sown in the ...

Permeable and antifouling PSf ‐Cys‐CuO ultrafiltration membrane for separation of biological macromolecules proteins
In this study, an ultrafiltration (UF) membrane was fabricated by dry-wet phase inversion to incorporate copper oxide nanoparticles (CuO NPs) with a different ratio of L-cysteine (Cys) in polysulfone (PSf). The characterization of the membrane involves using scanning electron microscopy (SEM), water contact angle, water content, pore size, and porosity analysis. The membrane performance evaluation includes flux permeation and bovine serum albumin (BSA) removal as a protein foulant. The membrane antifouling feature was examined by dynamic filtration of BSA. It was found that the Cys to CuO NPs ratio of 1.7:1 gives an optima...

Application of GIS ‐based DRASTIC model and its validation with Solute Transport Model in the assessment of groundwater vulnerability index: A case study from coal mining region of India
AbstractThe intensive Coal mining in Dhanbad, India, is crucial for contaminating the groundwater resources. The present work aims to estimate the vulnerability of aquifers to contamination with the aid of a GIS-based DRASTIC approach. This is finally validated by comparing the concentration of the contaminant computed by the Solute Transport Model. Using the soil moisture flow and pollutant transport model, an effort is made to validate the vulnerability of groundwater pollution. The vulnerability maps showed that some of this region's western southwest, and northern part lies in the highly vulnerable region. The major in...

Live foldscope imaging of two environmentally beneficial earthworm species and their early developmental stages
AbstractEarthworms are extensively referred as farmer's friends, play a vital role in maintaining soil fertility and promoting agricultural sustainability. Based on the ecological distribution of numerous species in soil the epigeic earthworms were taken into consideration as they have an excellent source for vermicomposting. In addition to this, earthworms also have a tremendous regeneration ability varies depending on the species.Eudrilus eugeniae andPerionyx excavatus are the two epigeic earthworm species were taken for the study. Species identification of newly hatched and juvenile earthworms are very difficult, due to...

Thermal management using nano coated heat sink for electric vehicle battery cooling
In this study, an attempt is made to examine the heating and cooling cycle, the time required to attain a target temperature, and the enhancement ratio of finned heat exchangers. The heat sink is provided with graphene nanocoating intended for electric vehicle battery cooling. The performance of the heat sink and its counterparts having two different types of pin fins, that is, circular and square, are compared. Four different heat inputs were considered, that is, 15, 25, 35, and 45 W. Three different target temperatures, that is, 46, 56, and 66°C, were accounted for during the comparison. It is concluded that the graph...

Investigation of heat transport characteristics of titanium dioxide nanofluids with corrugated tube
AbstractThe implications of cooling fluids with suspended titanium dioxide nanoparticles in augmenting the heat transfer rate in the heat exchanger are discussed. The application of corrugated tubes for increasing the effectiveness of heat exchangers is studied in this work. In deionized water, the nanofluid is synthesized to get three different volume concentrations (0.25%, 0.5%, and 1%). The nanofluid's flow rate varies to 100 L/h, 150 L/h, and 200 L/h, respectively. An experiment is carried out in three corrugated tubes made of copper, with pitch values of 18, 20, and 25 mm, respectively. Optimization is carried out t...

Performance evaluation and conservation of waste solid plastics into alternative fuel for a pollution ‐free environment
AbstractThe handling of waste plastics is a big challenge and various recycling routes are imposed to prevent the environmental ecosystem. Waste plastics are one of the major pollutants in the living environment and have characteristics such as non-dehydration and toxicity. The wastages are occupying natural lands and water source areas, decreasing the soil behavior, reducing the minerals, and affecting the environmental ecosystem. In this situation, waste plastics are effectively handled with a suitable recycling process that helps to minimize toxicity. According to the present research, waste plastics are handled by sepa...

Study the effects of dimethyl carbonate as a fuel cetane improver on diesel engine emissions
AbstractIn this work, diesel engine emissions are studied by adding a cetane improver to the engine fuel. Dimethyl carbonate (DMC) additive is used as a cetane improver. A single-cylinder, four-stroke diesel engine is used to test the fuels. Three fuels are selected to run the engine, namely, biodiesel derived from neem oil + 1 vol% DMC (BD100 + 1DMC), BD100, and diesel. BD100 + 1DMC fuel emits a reduced amount of carbon monoxide and unburnt hydrocarbons compared to diesel under the same operating conditions of engine. The level of nitrogen oxides emission for BD100 + 1DMC is slightly higher compared to diese l a...
