EFFECT OF CELLULAR CONCRETE POWDER ON DURABILITY OF NORMAL STRENGTH CONCRETE

found in the literature that air-entraining agent highly increases frost resistance of concrete [2]. However, the price of air-entraining agent is high compared to the total price of concrete. Besides that, air-entraining agents have negative effect on the compressive strength of concrete and usage is not allowed in case of some application area [3]. Another solution is the application of supplementary cementitious materials (SCMs, like metakaolin and silica-fume), which lowers the porosity of the

Low-ionic-strength saline solution–antiglobulin test (LISS-AGT)

The use of low-ionic-strength saline (LISS) solution as an enhancement for antibody screening and crossmatching was first described by Löw and Messeter in 1974. This method allowed for a reduced incubation time while maintaining adequate specificity and sensitivity of the antiglobulin test (AGT). Since then, the LISS-AGT tube method has been widely used in antibody detection and identification, as well as compatibility testing. As initially described, the method used red blood cells

The role of synaptic plasticity in disease is an active area of research. Changes in plasticity translate to the release of neurotransmitters at the synapse and subsequently, the way humans see the world. It is known that neuropsychiatric disorders such as depression, posttraumatic stress disorder (PTSD), and Alzheimer’s disease (AD
