Determination of the Flow Velocity Resistance in Non- Submerged Woody Plants
Abstract: Vegetation on the bank of a river or stream has a major influence on resistance, velocity distribution,and turbulence force. The resistance to flow in open channels depends on different channel and flow parameters. Out of many factors, vegetation is the mainly important parameter in open channels. In this study have been five points to measure the velocity in the channel. The experimental work has been done by a rectangular channel …

Pitaya Cactus Endophytic Bacteria a Sustainable Option to Reduce and Optimize NH4NO3 in Phaseolus vulgaris
Abstract: The Phaseolus vulgaris crop demands nitrogen fertilizer as NH4NO3 for healthy growth. However, the application of NH4NO3 not uptaken by plant roots, generates N2O, a gas that contributes to the greenhouse effect besides loss of soil fertility; a sustainable option is to reduce up to 50% and to optimize it by inoculating P. vulgaris seeds with genera and species of plant growth promoting endophytic bacteria isolated from a desert xerophyte …

Use of Pesticides leads to Environmental degradation
Abstract: Pesticides are extensively used for agriculture but residues can reach aquaticecosystems, frequently. They are transferred from pytoplankton to fish and human, ultimately. Pyrethroid insecticides are utilized in place of organochlorine,organophosphorus and carbonate to control different forms of pests and raise yield. Pyrethroid intoxication causes cellular damage and increases freeradicals, which leads to lipid peroxidation and, ultimately, oxidative stress.To reduce damage to environment and biologicalsystems by pesticides should be played attention …

Ultrasonic Study of Binary Liquid Mixtures of Triethyl Amine With Primary Alcohols at 303.15 K
Abstract: Most of the physical properties change whenever there is a change in the composition and structure of the liquid mixture. Then non-linear dependence of the physical–chemical properties with composition has been attributed to the size, shape, and polarity of the molecules. Ultrasonic velocity is one such property which is very important for the study of molecular interactions in solution. It gives information about the extent of interaction and some other …

Several Phases of Binary Liquid Mixture
Abstract: The system’s overall composition, heat, and stress can all be changed independently. Instead of using parameters like the coordinates of a three-dimensional phase diagram, we often generate a twodimensional phase transformation that is either a thermal diagram at a specified pressure or its composition graph at a fixed temperature. The location of the system points on one of these diagrams correlates to a certain heat, stress, and normal phenomenon. As …
