In this paper we consider a kind of higher-order evolution equation as^{kt^{k} + ^{k&minus1}u/t^{k&minus1} +• • •+ut &minus{delta}u= f (u, {delta}u,x). For this equation, we investigate nonglobal solution, blow-up in finite time and instantaneous blow-up under some assumption on k, f and initial data. In this paper we employ the Test function method, the eneralized convexity method an...

background and objective: the production of carbapenemases especially klebsiella pneumoniae carbapenemase (kpc) is the most important mechanism of enzymatic resistance in isolated enterobacteriaceae such as k. pneumoniae. the purpose of this study was detected of the carbapenemase producer k. pneumoniae strains with phenotypic and genotypic methods. method: out of 800 strains, 270 k. pneumoniae...

Prestack migration algorithms are usually divided into two classes: ray-tracing based migration methods and wave-equation methods. The latter methods provide more accurate migration images, especially in complex geological areas, but they are the relatively expensive compared with ray-based migration methods. In this work, I test the phase encoding strategy on three types of one-way wave equati...

An assessment of the intellectual potential scientific personnel on platform electronic demography was carried out. The current situation in field forming population registers, conducting demographic studies, as well a number works related to use new sources information and big data have been studied. Analyzed studies cover human resources, country issues migration. To determine factors influen...

PURPOSE This study was designed to determine in human corneal epithelial cells (HCEC) whether the balance between epidermal growth factor (EGF)-induced increases in proliferation and migration is dependent on the duration and magnitude of extracellular signal-regulated kinase (Erk)1/2 activation. METHODS Western blot analysis evaluated the phosphorylation status of Erk1/2 and phosphoinositide...
