Many of the stability characteristics of horse ferrihemoglobin (Hb+) in acid solutions, such as pH dependence and susceptibility to stabilization by iron ligands, are shared by human ferrihemoglobin, but striking differences between the two proteins exist. The most noticeable is the much greater rate of denaturation of the human protein at all pH values. Other differences include a shift to hig...

Desiccants can be used in conjunction with solar energy to provide a viable alternative to traditional air conditioning techniques. Liquid desiccant regeneration was proved to be an effective method to extract the moisture from solution with a relatively less energy in order to regenerate the desiccant. An experimental study was carried out to analyze the effect of temperature for regeneration ...

Local strain measurements are considered as an effective method for structural health monitoring of high-temperature components, which require accurate, reliable and durable sensors. To develop strain sensors that can be used in higher temperature environments, an improved metal-packaged strain sensor based on a regenerated fiber Bragg grating (RFBG) fabricated in hydrogen (H₂)-loaded boron-ger...

Six patients had penetrating keratoplasty following thermokeratoplasty (TKP) at different time intervals. The standard temperature used was between 90 degree and 95 degree C. with constant saline irrigation. The corneal buttons were studied by light and electron microscopy. Immediate changes observed included epithelial necrosis, marked degneration of keratocytes, and endothelial edema. After 2...

In this paper, a novel solar solid dehumidification/regeneration bed has been proposed, and its three regeneration methods, i.e., simulated solar radiation regeneration, microwave regeneration, and combined regeneration of the microwave and simulated solar radiation, were experimentally investigated and compared, as well as the dehumidification performance. The degree of regeneration of the pro...

Both temperature and strain characterization of seed and regenerated gratings with and without post annealing is reported. The high temperature regeneration has significant impact on thermal characterization and mechanical strength of gratings while the post annealing has little effect. The observed difference is evidence of viscoelastic changes in glass structure.

The conditions for optimal formation and regeneration of protoplasts of Streptomyces clavuligerus were established. The optimal temperature for regeneration of protoplasts and for transformation was 26 degrees C in three different regeneration media. The best efficiency of transformation was obtained with 40% polyethylene glycol 1000. The efficiencies of regeneration and transformation increase...
