abstract background: inadequate dialysis is one of the main causes of mortality of the patients undergoing hemodialysis. the methods that lead to improvement of dialysis adequacy in these patients are of great importance due to them causing an improvement of quality of life. as numerous factors can play a role in improvement of dialysis adequacy, the present study aimed to investigate the level...
background : one of the most prevalent side effects of hemodialysis is intradialytic hypotension and its symptoms. using sodium profiles 3 and ultra filtration profile 3 and cold dialysate are the ways to overcome this problem. since none of these methods could control this complication lonely, this study was done to investigate the effect of combination of two methods on intradialytic hypotens...
Background and purpose:Intradialytic hypotension (IDH) is the most frequent complicationin patients receiving haemodialysis (HD) that poses most problems for patient and treatment team. The use of sodiumprofile and ultra filtration (UF) profile is one of the preventive methods that have been recently introduced. However, increased intradialytic weight gain (IDWG) has been described as the sid...
Background & Aim: Intradialytic hypotension is the most frequent complication in patients receiving haemodialysis (HD). This complication not only contributes to the illness of the patients, but also decreases the efficacy of the HD. So, hypotension prevention is a major challenge for medical team, especially for nurses. One of the preventive methods that have recently been presented is the use...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
regarding many disadvantages of traditional method to produce concentrated yoghurt, several attempts have been done for mechanization of process in industrial scale. using membrane systems especially ultra filtration is one of these methods. in this survey, method to produce direct concentrated yoghurt, fresh milk was concentrated to 19% snf by ultra filtration method then diluted to 13 and 16 ...
date juice was treated by cross- flow ultra-filtration with molecular weight cut-off (mwco) of 5 kda. optimized levels of feed brix, tmp and operation time were determined as 47.13, 82.11 psi and 30 min, respectively. under such conditions, 80.94% decolourisation and 97.78 % turbidity reduction were obtained while loss of glucose and fructose were estimated to be only 3.49% and 9.62%, respectiv...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
New nanofiltration membranes were produced in the form of unfilled fibers through the photopolymerization method. Parastyrene sodium sulfonate was used as the vinyl monomer to reform the polysulphone ultra-filtration membranes. The modified membranes were used to purify colored solutions of three different pigments consisting acidic, reactive and direct (suitable for dyeing pile yarns and ...
