maharlou-bakhtegan catchment in the southern part of iran is faced with water scarcity.this problem is exacerbated by environmental degradation, climate change effects, mismanagementof water resources, along with a major dependence of water demand supplies on the limitedgroundwater resources. in this study, a combined approach of dpsir model along with the scenarioanalysis was employed to deriv...

in this paper, we obtained the 1-soliton solutions of the symmetric regularized long wave (srlw) equation and the (3+1)-dimensional shallow water wave equations. solitary wave ansatz method is used to carry out the integration of the equations and obtain topological soliton solutions the physical parameters in the soliton solutions are obtained as functions of the dependent coefficients. note t...

A new theory model based on the local composition concept (TNRF-modified NRTL (TNRF-mNRTL) model) was developed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. An equation represented the activity coefficient of solvent was derived from the proposed excess Gibbs energy equation. The short-range contribution of interaction ...

Peripheral parenteral nutrition (PPN) solutions contain amino acids, glucose, and electrolytes, with or without some water soluble vitamins. Peripheral venous catheters are one of the causes of catheter related blood stream infection (CRBSI), which requires infection control. In Japan, PPN solutions have rarely been prepared under aseptic conditions. However, in recent years, the necessity of a...

in this work the acidity constants of thiamine in water and water-triton x-100 micelle media solutions, at 25 °c, have been determined spectrophotometrically. to evaluate the ph- absorbance data, a resolution based on the combination of soft-and hard-modeling is applied. the acidity constants of all related equilibria are estimated using the whole spectral fitting of the collected data to an es...

New technologies are emerging that may offer potential remedies to persistent global problems of lack of access to safe drinking water, insufficient or non-existent healthcare, and inadequate energy sources. The challenge in applying nanotechnology, biotechnology, and other emerging technologies to human needs is moving beyond the traditional technology-transfer model, where expertise and resou...
