This study aimed to investigate the effect of combining an innovative bioceramic α-calcium sulfate hemihydrate (α-CSH, CaSO4⋅0.5H2O) bone graft and platelet-rich plasma (PRP) accelerate healing regeneration in a rabbit model. The material was implanted bilaterally on rabbit’s artificially maxillary sinus defects: right received α-CSH, while α-CSH combine with PRP (α-CSH/PRP) grafted left site. ...

This paper presents a technique to improve the performance of TCP and the utilization of wireless networks. Wireless links exhibit high rates of bit errors, compared to communication over wireline or fiber. Since TCP cannot separate packet losses due to bit errors versus congestion, all losses are treated as signs of congestion and congestion avoidance is initiated. This paper explores the poss...

To modulate the rate of hydration calcium sulfate hemihydrate (HH) to dihydrate for industrial applications, additives (both accelerants and retardants) are added HH. Here we explore in detail kinetics mechanism HH presence accelerators K 2 SO 4 or ZnSO , also when a retardant (citric acid tartaric acid) is added. Retardants tend lower maximum temperature reaction increase time needed reach 50%...
