Since isospin symmetry is only approximate, the discrepancy in this relation, D ; fCEX 2 sf1 2 f2dy p 2, is expected to be nonzero. Interesting physics lies in the violation of this relation beyond effects due to the hadronic mass differences and the Coulomb interaction. It is the purpose of this Letter to demonstrate that recent experimental data at low energies require a residual contribution...

A chimaera of stem cell factor (SCF) and a cellulose-binding domain from the xylanase Cex (CBDCex) effectively immobilizes SCF on a cellulose surface. The fusion protein retains both the cytokine properties of SCF and the cellulose-binding characteristics of CBDCex. When adsorbed on cellulose, SCF-CBDCex is up to 7-fold more potent than soluble SCF-CBDCex and than native SCF at stimulating the ...

Objective: The main objective of this study is to assess the feasibility in replacing portfolio a low resource setting and its acceptance amongst students staff. Synopsis: for with regards using portfolios: it feasible 2 month professorial appointment Methods: was conducted on 259 final year medical period two years from 2016 2018, student maintained by them during their gynaecology obstetrics ...

The charge-exchange xenon (CEX) ion generated by ion thruster can backflow to the surface of spacecraft and threaten to the safety of spacecraft operation. In order to evaluate the effects of the induced plasma environment in backflow regions on the spacecraft, we designed a spherical single Langmuir probe of 5.8cm in diameter for measuring low-density plasma parameters in backflow region of io...

introduction: feedback cards are recommended as a feasible tool for structured written feedback delivery in clinical education while effectiveness of this tool on the medical students’ performance is still questionable. the purpose of this study was to compare the effects of structured written feedback by cards as well as verbal feedback versus verbal feedback alone on the clinical performance ...
