Should you go around and seek fro the book until you really get it? Are you sure? Are you that free? This condition will force you to always end up to get ...
Inclusive single-particle production cross sections have been calculated including higher-order QCD corrections. Transverse-momentum and rapidity distributions are presented and the scale dependence is studied. The results are compared with experimental data from the CERN Spp̄S Collider and the Fermilab Tevatron. Supported by the Bundesministerium für Forschung und Technologie, 05 5HH 91P(8), Bo...
The purpose of this study was to investigate the effectiveness of expressive art group therapy on internalized problems and emotional-functional profiles of parentless and poor-parenting children. The design of this research was quasi-experimental, pre-test, and post-test with the control and sham-control group. The study's statistical population consisted of all parentless and poor-parenting b...
Introduction: The skin, can be exposed to harmful factors like ultraviolet radiation (UV). Exposure to this physical hazardous agent could be contributed to pigmentation, erythemas, early aging, skin cancer, and DNA damage. The aim of this study, therefore, was to fabricate the polyacrylonitrile (PAN) nanofibers with the UV protection property by the use of various concentrations of titanium di...
Conceptual problems of unified two-nucleon force models are discussed. The force models are based on the pion-nucleon vertex and attempt a description of the nucleon-nucleon interaction below and above pion threshold. The conceptual problems arise from the nucleon renormalization due to pionic degress of freedom. Keeping channels with a single pion only no renormalization procedure can be given...
just as motivation is important in sla research, demotivation constitutes an important factor, too. there are many studies done on demotivation and burnout of teachers. many of these studies have been conducted on one or two aspects of english instruction. consequently, there are few studies which have been done on more than two aspects of english teaching. the aim of this study is to find out ...
