Abstract This study aimed to evaluate the prevalence and trends of transfusion-transmitted infections (TTIs) in two hospitals Riyadh, as well judge best type tests ensure blood transfusion safety. By using serological nucleic acid test (NAT) tests, these donors were screened for human immunodeficiency virus (HIV), hepatitis C (HCV), B (HBV), T-lymphotropic 1 (HTLV-1), 2 (HTLV-2), syphilis, mala...

Whis work presents a study on the flammability of epoxy coatings containing two types of nano-scale fillers as potential flame retardants: expandable graphite (EG) and halloysite nanotubes (HNTs). Both nanocomposites are prepared by incorporation of the same amount of nanofiller into the epoxy resin for the sake of comparison. Fire retardant nanocomposite coatings are cured through a two-stage ...

Screening technologies aimed at identifying such transfusion transmissible infections (TTI) as hepatitis B and C, HIV-1,2 syphilis have been developing this has resulted in increased safety of applied hemotherapy. Our research goal was to analyze detection infectious markers donors the FMBA Blood Center over five years. We examined 167,389 samples donor blood taken from 53,093 its components by...

This paper introduces a 9L T-type boost inverter (9L-TTI) based multilevel topology, which generates nine-level output voltage in the mode. topology uses 12 switching elements alongside less stress and one switched capacitor unit. is significant advantage of mentioned topology. Following discussion advantages provided design, comparative study conducted. results reduction device counts, cost-ef...

An improved time diversity technique is proposed for deploying the 3GPP LTE airinterface over satellite mobile links. It overcomes the FEC performance loss resulting from the use of a short transmit-time-interval (TTI) in LTE. By using transport block expansion, code block segmentation, advanced rate matching and automatic retransmissions, the FEC coded block is split over as many TTIs as is ne...
