In order to improve the anti-seepage performance of cover, this paper proposed use super absorbent polymer (SAP) particles water storage capacity soil, and mixed them into soil build an SAP composite but law movement in which is not clear. paper, a series column model tests were carried out measure changes pore pressure volume content cover at different depths. The results showed that under ext...

Detection and quantification of pathogens in water is critical for the protection of human health and for drinking water safety and security. When the pathogen concentrations are low, large sample volumes (several liters) are needed to achieve reliable quantitative results. However, most microbial identification methods utilize relatively small sample volumes. As a consequence, a concentration ...

OBJECTIVE Trans-catheter aortic and pulmonary valve replacement procedures can result in favorable outcomes in selected patients. The aim of this study was to investigate the functioning of a novel self-expanding valved stent with super-absorbent polymer (SAP) for minimally invasive replacement of the tricuspid valve. METHODS A newly designed nitinol stent with SAP was specially designed for ...

World population is increasing at an alarming rate, and crop cultivation on marginal lands has emerged as alternate option to feed the burgeoning population. However, are characterized by poor soil health other undesirable characteristics resulting in low production less economic returns. Interest application of superabsorbent polymers (SAPs) for been increasing. The SAPs increases germination ...

in order to investigation the effects of different combination and amount of chemical, biological and organic manure in present of water absorbent materials on some phenological, morphological and yield of soybean, a field study was carried out gorgan region climate conditions in a factorial experiment based on randomized complete block design with three replications. in this experiment two lev...

Abstract Super-absorbent polymer (SAP) is able to absorb water by multiple times more than its own weight. Sugarcane bagasse (SCB) raw material has been excessively produced as a byproduct in sugar factory. The synthesis of SAP from SCB creates balance between the utilization industrial by-product and resulted environmentally friendly material. In oil production might be troublesome, thus minim...

Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran. Application of some materials such as super absorbent polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The aim of the study was to estimate the relative membrane permeability of sorghum under irrigation regimes and superabsorbent polymer applicat...
