background: in spermatogenesis, spermatogonial cells differentiate to the haploid gametes. it has been shown that spermatogenesis can be done at in vitro condition. in vitro spermatogenesis may provide an open window to treat male infertility. objective: the aim of this study was to evaluate the effects of a novel scaffold containing human serum albumin (hsa)/tri calcium phosphate nanoparticles...

Starting powders of silicon-substituted beta-tricalcium phosphate (β-TCP/Si) were prepared by the polymerized complex method. Silicon ions blended up to 3.0 mol% total P content. The raw product powder was calcined at 1000 °C, formed into pellets, and sintered 1120 °C for 24 h. resultant bodies showed that a single phase β-type tricalcium (β-TCP) can be obtained with silicon addition 0-2.0 subs...

Tricresyl phosphate (TCP) forms protective films on moving mechanical components through thermally driven decomposition and interactions with the ferrous surfaces of components. These reactions are hidden from view in interfaces, but known to be sensitive both surface material isomeric form TCP. Here, temperature-programmed reaction spectroscopy (TPRS) gas chromatography-mass (GC-MS) complement...

Objective- The aim of this study was to evaluate possible beneficial effect of tricalcium phosphate/collagen (TCP/collagene) nanocomposite scaffold on bone healing in rabbits using biochemical assessmentsDesign- Experimental studyAnimals- Twelve healthy male white New Zealand rabbitsProcedures- The rabbits wer...

The present work investigates the crystallization and phase evolution of amorphous calcium phosphate (ACP) partially substituted with smaller (Mg2+, Zn2+) larger (Sr2+, Ba2+) divalent ions in range from 1 to 10 mol % (M/P = 1.5:1). It has been demonstrated that ACP tricalcium (TCP) subsequent transformations between TCP polymorphs strongly depend on nature concentration substituents matrix. Two...

Since tubes have numerous industrial applications, different attempts are focused on the Severe Plastic Deformation (SPD) processes of tubes. As an illustration, Tube Channel Pressing (TCP) is an attractive process for this purpose since it can be used for processing of different sizes of tubes. However, more attempts are needed to improve the outcomes of TCP. For example, imposing of greater s...

The need to ensure the quality of video streaming transmitted over wireless networks is growing every day. Video typically used for applications that are sensitive poor service (QoS) due insufficient bandwidth, packet loss, or delay. These challenges hurt since they affect throughput and delivery video. To achieve better quality, must be high, with minimal delay loss ratios. A current study, ho...
