The application of railway wheel noise compensation method is considered. The effect can be obtained by shift a pair of usual parallel rail joints on a pair of offset rail joints, for example, the right rail joint is shifted concerning the left rail joint on the certain dist.nce. The dist.nce is depend on the speed of train and promotes the correlation interconnection between excited acoust.cal pulses. The intensity wheel knock spectrograms corresponding of different dist.nce between rail joints regist.red by the microphone are est.mated. The spectrograms considerably differed from each other in low frequency band are analyzed. The result of practical using the acoust.c noise compensation method is proved.

Pathophysiology transforms to pathobiology:new technologies and interdisciplinary project-oriented learning

中国病理生理杂志 2009年第11期25卷 2248-2248页

Integrative role of pathophysiology in medicine is analogous to that of syst.mic biology among non-medical life sciences. Pathology rooted in morphology,because autopsy and microscopy in early 19th century revealed some loci and elements of disease. However,this was not enough for comprehension of syst.mic disorders and relations between elements. This promoted the involvement of physiology and birth of pathophysiology. For a long time the methodological options for bedside st.dies were scarce,so generations of physicians percepted pathophysiology as a science of lab and vivarium only,unlike pathomorphology,had integrated in clinics earlier. This lead to fornication between two sist.r branches of pathology and teaching of pathology and clinical subjects separated. Methodological progress of 20th century created basis for less or non-invasive patient st.dies. Current advances of pathochemist.y,medical genetics,immunopathology,bioinformatics-give the chance to pathophysiology and pathomorphology spread far beyond the const.aint of their hist.rical names and intermingle. Current Pathophysiology grew into clinics (via laboratory and functional diagnosis,which contains clinical experimenting). This promotes re-integration of pathology sist.r branches,not via absorption,but through mutual shift to clinical correlations. Holist.c approach to patient,disease and education is traditional for Russian medicine. In our pathophysiology teaching,classical lab experiments are joint to early st.rt of clinical pathology (6th term),case hist.ry analysis,lectures co-delivered by pathologist.and clinician with demonst.ation of patients. Pathomorphologist.and clinician are included in state board for pathophysiology exam. In teaching post.rs pathophysiological,clinical and pathomorphological data are fused. Local net of digital television microscopes gives inst.nt video archive of experimental results added to st.dent's protocols of lab st.dies. Teaching post.rs and course papers are co
