Lime mortar is as old human civilization. But replaced with Cement binding material which widely utilized today. need for reduction in environmental pollution turning the tide against cement. admixtures are tried various researches nowadays. In this paper lime of 1:3 ratio Agricultural complex (NPKS) urea and Super phosphate percentages such 1, 2, 3, 4 5 studied. Commercial available market was...

I. In eight females, serum urea concentrations of 134-336 ml\l/l. were interpreted as indications of previous environmental salinities. 2. Fetal serum solute concentrations usually resembled those of the mother, but in two cases where fetal urea was higher, it was interpreted as a lag in urea reduction following movement from salt to fresh water. 3. Uterine fluid was similar to maternal serum i...

When compared to intermittent dialysis, the theoretical advantages of continuous dialysis may be less important than its practical disadvantage: the inability to accurately quantify dialysis. With intermittent dialysis the change in blood urea nitrogen over the course of the treatment allows the ratio of K (urea clearance) to V (volume of distribution of urea or total body water) to be determin...

I N PREVIOUS work, it was found that the ‘osmotic ceiling’ in the urine from the desert rodents Heteromyidae is exceptionally high compared with the osmotic ceiling in urine from other mammals. This mechanism is of importance to water conservation. The general objective of the further investigations was to find in what respects the function of the heteromyid kidney differs from that of other ma...

The urea tests of renal efficiency commonly mentioned in the literature include (a) simple estimation of blood urea concentration, (b) determination of urine urea concentration following ingestion of urea, and (c) observations on the relationship between blood and urine urea concentrations. From a comparative study of these three methods, the general conclusion reached in this hospital (1) was ...

According to the usually accepted concept, the urea removed from the blood by the kidneys is excreted in two forms, chiefly as urea itself, but partly as ammonia. That the ammonia of the urine is formed in the kidneys was demonstrated by Nash and Benedict (1921), in work which has been confirmed by other authors (cf. Peters and Van Slyke, I, p. 373). Evidence from animal experiments in v4vo has...

Urea effect on conformation and thermal stabilities in nucleohistone and NaCl-treated partially dehistonized nucleohistones has been studied by circular dichroism (CD) and thermal denaturation. Urea imposes a CD change at 278mm of DNA base pairs in native and NaCl-treated nucleohistones which can be decomposed into two parts: a decrease in Deltaepsilon(278) for histone-free base pairs and an in...

The conventional, low flux (LF) dialyser allows the removal of small molecular solutes like urea and creatinine. The removal of middle molecules (molecular weight between 500D and 60,000 D, which is nearly the size of albumin) is relatively low. Cystatin C has attractive characteristics as a representative middle molecule. Objective: To determine per dialysis Cys C reduction ratio (RR) in low f...
