this paper examines the evolution of nationalism and national identity in europe and how it was transferred to and propagated in central asia by the soviets. it further examines the challenge facing central asian peoples in the post-soviet era; namely in defining a new national identity for themselves as new independent nation-states in the age of globalization. the paper attempts to demonstrat...
We show that the existence of disintegration for cylindrical measures follows from a general disintegration theorem for countably additive measures.
We study neural connectivity in cultures of rat hippocampal neurons. We measure the neurons’ response to an electric stimulation for gradual lower connectivity, and characterize the size of the giant cluster in the network. The connectivity undergoes a percolation transition described by the critical exponent β ≃ 0.65. We use a theoretic approach based on bond–percolation on a graph to describe...
Marked degeneration and disintegration of the chick embryo fibroblast was observed in tissue cultures after their exposure to sera of patients with active or inactive rheumatic heart disease or to the filtrates of beta hemolytic streptococci. Some tissue specificity was demonstrated; sera of the patients or the filtrates of the streptococci failed to affect contractility of the myocardial cells...
هدف از انجام این مطالعه مقایسه دو روش mpn-pcr و mpn-culture در شمارش باکتری لیستریا مونوسیتوژنز تلقیح شده به شیر استریل می باشد. برای انجام این کار تعدادcell/ml 103 از باکتری لیستریا مونوسیتوژنز و نیز باکتری های زمینه ای مختلف به شیر استریل تلقیح شدند. پس از آماده سازی رقت های متوالی، از هر رقت در سه لوله حاوی محیط غنی کننده لیستریا تلقیح شد. پس از 48 ساعت گرمخانه گذاری، برای آزمایش mpn-cultu...
The use of hydrodynamic disintegration as a means to improve anaerobic digestion of activated sludge
Disintegration by hydrodynamic cavitation has a positive effect on the degree and rate of sludge anaerobic digestion. By applying hydrodynamic disintegration the lysis of cells occurs in minutes instead of days. The intracellular and extracellular components are set free and are immediately available for biological degradation which leads to an improvement of the subsequent anaerobic process. H...
Drug product performance testing is an important part of quality-by-design approaches, but this process often lacks the underlying mechanistic understanding of the complex interactions between the disintegration and dissolution processes involved. Whereas a recent draft guideline by the US Food and Drug Administration (FDA) has allowed the replacement of dissolution testing with disintegration ...
