The performance of concrete primarily depends upon the type and ratio of its constituents, compaction, curing conditions and admixtures used during curing process. Part of this research emphasis to calculate the consequences on strength of concrete when water-cement ratio is constant and the increase in slump occurs with the increase in amount of superplasticizer by percentage. The rest of the ...

The long-term durability of varnished wooden surfaces used in either indoors or outdoors environments depends on the resistance of varnish layers on these surfaces against potential physical, mechanical and chemical effects to which they may be exposed. In this study, "Nanolacke ultraviolet varnish", developed by a Turkish dying and varnish industry company and widely accepted as a 21(st) centu...

We present continuum observations of a small sample of high-redshift, radio-loud AGN (radio galaxies and quasars) aimed at the detection of thermal emission from dust. Seven AGN were observed with IRAM and SEST at 1.25mm; two of them, the radio galaxies 1243+036 (z ∼ 3.6) and MG1019+0535 (z ∼ 2.8) were also observed at 0.8mm with the JCMT submillimetre telescope. Additional VLA observations wer...

Results Hemodialysis: Of the 28 patients not undergoing renal transplantation (Tx) in Armenia, 9 died (systemic amyloidosis 5, heart attack 2, stroke -2); 15 moved to another country and 4 remained on dialysis. Over half of the 25 pts with minimum observation period of 6 mo were resistant to EPO. One third died, mainly due to cardiovascular complications and systemic amyloidosis. Living related...

The mechanisms underlying the computation of visual motion in biological systems are explored. Psychophysical experiments in visual perception of apparent motion (sequences of static images as in film, video, or computer controlled displays) were performed using random dot apparent motion stimuli designed to isolate populations of biological motion detectors. The results of these experiments al...

Introduction Temperature has immunomodulatory effects on innate immune cells: incubating monocytes at low temperatures for example increases pro-inflammatory responses after LPS-stimulation. The mechanisms mediating this effect are still unclear. The activity of several ion channels is sensitive to changes in temperature, leading to cytosolic calcium influx. Calcium is universally involved in c...
