As the insulated gate bipolar transistor (IGBT) modules have their own specific characteristic switching forms, turn-on and turn-off times are changed according to practical applications. For conventional drives, resistors used adjust which change losses that a significant amount in total losses. Collector current rate of change, $di_{C}/ dt$ collector-emitter $dv_{CE}/ dependent on each other ...

The reaction of antimony(III) chloride with 1,4-dithiane (1,4-dt) in the ionic liquid [BMIM]Cl ([BMIM]Cl: 1-butyl-4-methylimidazolium chloride) with an excess of the Lewis acid AlCl3 results in the formation of a ligand-stabilized stibenium cation [SbCl2]. 1,4-Dithiane simultaneously serves as a chelating η2-ligand, exhibiting a boat-like conformation, as well as a bridging μ2-ligand, exhibitin...

Preparation of chitosan (CS) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low CS molecular weight (MW) was investigated in this study. Diphtheria toxoid (DT) was used as a model antigen. The emulsion-solidification method was adopted for microencapsulation of DT.  In the first step, following the purification of semi-crude DT by the ion-exchan...

Multiresistant Salmonella enterica serotype Typhimurium definitive phage type (DT) 12 and DT 120 are more closely related to DT 104 than to non-multiresistant strains of their respective phage types. Multiresistant DT 12 and DT 120 appear to have arisen due to changes in phage susceptibility of DT 104 rather than horizontal transfer of resistance genes.

Background. The reactive abilities of goalkeepers are crucial and may directly impact match results. Therefore, research on factors that may enhance goalkeeper performances during diving tasks (DT) and how these factors are mediated would provide valuable information for coaches and goalkeepers. Objectives. The purpose of this investigation was to: (i) assess the impact of caffeine consumption...
