This studys primary goal was to track biodiversity loss and present land-use practices in the Jamuaari river basin and their effects on the river ecosystems nitrogen load. Numerous researchers in India have studied the physicochemical characteristics of rivers and the toxicity of the pesticide glyphosate (Chaturvedi, 2006). Scientists have recently discovered that pesticides have detrimental impacts on living things, such as genotoxicity, cancer, endocrine disruption, and reproduction (Mose et al., 2008; Gasnier et al., 2009). Although there has been some research on the immunological examination of rivers (Kumar Sinha, 2005), it is not comprehensive. Prior and tributary basins of the Jamuaari river in the Sarairanjan block of south Samastipur have not yet been studied in this way from a physicochemical, ecological, and zoo geography standpoint. Thus, this study was conducted. Five years in total The primary factor influencing nutrient loads and productivity was the concentration of phosphate and bicarbonate, which varied from 30/1 to 90/5 during the course of the five-year period. Five-year soil and water samples verified that eutrophication rose as herbicide use increased, and that the biodiversity of the tributary basin differed significantly from that of the majority of sampling locations. In contrast to the distant majority of the riverbank (5/2.2,5/1.4,5/5.5, site IV, site V, and site VI), the seasonal phosphate and bicarbonate concentration change was greatest in the tributary basin (65/5.3,60/3.7,15/1.8, site I, site II, and site III), primarily at site I.The tributary basin (35/0.2,25/1.6,20/0, sites I, II, and III) had the biggest phosphate and bicarbonate concentration change over the course of five years, primarily at site L, in contrast to the vast majority of the riverbank (5/0.4,0/0,5/1.4, sites IV, V, and VI). Keywords: Herbicide-induced cultural eutrophication, dual-nature pesticides, and the aquatic zoogeography of the Jamuaari River http://www.scientiaresearchlibrary.com/archive-abs.php?arc=918http://www.scientiaresearchlibrary.com/archive/An investigation of the effects of chemical pesticides and eutrophication in the Jamuaari River in Samastipur North Bihar.pdf

Pectin Reinforced by ZNO/Cellulose Nano Whiskers for Antimicrobial Food Packaging Scientia Research LibraryJournal of Applied Science And Research2348 - 04162023116 Poumit pages:1-10 1 This article describes how the solution casting technique was used to create cellulose nanowhiskers with a pectin matrix obtained from coconut husk fiber. Along with the plasticizing agent and lipid in the proper composition, it also contains a trace amount of zinc oxide nanoparticles (made by the hydrothermal process) to enhance antibacterial action. Two distinct peaks, 2 = 36.4569 and 22.7, show the crystal geometry of cellulose and ZnO nanowhiskers. Thermoelectric SEM reveals a cellulose nanowhisker-like morphology with spherical ZnO nanoparticles (50-80 nm) and rods (aspect ratio 6- 10). AFMs topographical examination verifies that the reinforced materials are uniformly impregnated. The usage of pure ZnO nanoparticles (nps) with cellulose nanowhiskers is demonstrated by the FTIR spectrum. Additionally, the Universal Testing Machines calculations of the nanocomposites films tensile strength and elongation at break demonstrate a significant improvement. Additionally, food packaged with the produced nanocomposite film was free of microbiological development, extending the food products shelf life and safely preserving its quality. Keywords: Pectin, Cellulose nanowhiskers, Zinc oxide, Polymer nanocomposite film, antimicrobial. http://www.scientiaresearchlibrary.com/archive-abs.php?arc=919http://www.scientiaresearchlibrary.com/archive/Pectin Reinforced by ZNOCellulose Nano Whiskers for Antimicrobial Food Packaging.pdf
