There are different methods and devices for the increase of the videosignal information in SEM. For example, with the help of special pure electronic [1] and opto-electronic [2] systems equipotential areas on the specimen surface in SEM were obtained. This report generalizes quantitative universal method for space distribution representation of research specimen parameter by contour equal signal lines. The method is based on principle of comparison of information signal value with the fixed levels.Transformation image system for obtaining equal signal lines maps was developed in two versions:1)In pure electronic system [3] it is necessary to compare signal U (see Fig.1-a), which gives potential distribution on specimen surface along each scanning line with fixed base level signals εifor obtaining quantitative equipotential information on solid state surface. The amplitude analyzer-comparator gives flare sport videopulses at any fixed coordinate and any instant time when initial signal U is equal to one of the base level signals ε.

Background/Purpose: Surgical site infection surveillance to determineincidence is a key infection control activity. Case detection is labour-intensive, therefore most infection control programs use manual or simple electronic mechanisms to “trigger” chart review. However, such “trigger” mechanisms are also labour-intensive, and often of poor specificity. Our objective is to develop a complex trigger mechanism using data from an electronic data warehouse, to improve specificity of surveillance of surgical site infection compared to current trigger mechanisms. Methods: We will derive an electronic trigger tool for cardiac surgical site infection surveillance using a nested case-control design, among a cohort of all patients undergoing coronary artery bypass grafting, cardiac valve repairor replacement, or heart transplant at the University of Ottawa Heart Institute, from July 1 2004 to June 30 2007. We will perform a systematic literature review to identify potential trigger factors to include in the model, then construct the trigger tool by backwards stepwise logistic regression. The best-fit model will be used to calculate the probability of surgical site infection. We will select the threshold probability to use in surveillance by visual inspection of receiver-operator-characteristic curves. The accuracy of this electronic trigger mechanism will be compared to pre-existing manual and simple electronic mechanisms using relative true positive ratios and relative false positive ratios. Results/Conclusions: We have selected 200 cases of surgical site infection and 541 controls from among 3744 procedures performed during the study period. As of the date ofthis abstract we are still undertaking the systematic review.

Digitization offers significant opportunities for the formulated product industry to transform the way it works and develop new methods of business. R&D is one area of operation that is challenging to take advantage of these technologies due to its high level of domain specialisation and creativity but the benefits could be significant. Recent developments of base level technologies such as artificial intelligence (AI)/machine learning (ML), robotics and high performance computing (HPC), to name a few, present disruptive and transformative technologies which could offer new insights, discovery methods and enhanced chemical control when combined in a digital ecosystem of connectivity, distributive services and decentralisation. At the fundamental level, research in these technologies has shown that new physical and chemical insights can be gained, which in turn can augment experimental R&D approaches through physics-based chemical simulation, data driven models and hybrid approaches. In all of these cases, high quality data is required to build and validate models in addition to the skills and expertise to exploit such methods. In this article we give an overview of some of the digital technology demonstrators we have developed for formulated product R&D. We discuss the challenges in building and deploying these demonstrators.<br>

In this paper, there will be analyzed the determinants of the inter-ethnic conflict that occurred in the Fergana Valley in the Kyrgyz city of Osh in June 2010. In such a phenomenon as an inter-ethnic conflict, it is rather difficult to find out a single cause of events; it is rather a set of economic, social, demographic, cultural and historical factors that are in a particular political context. And by the summer of 2010 a political context was formed: as a result of the April coup, there was a change of elites in the state power, which led to the struggle for the redistribution of economic power and resources. And in the conditions of connections of power and economic structures with the criminals, that was clearly manifested in the country on the eve of the conflict, the contradictions became ethnic. Despite the fact that this ethnic conflict was the result of objective contradictions caused by lack of resources (primarily land), low living standards, demographic and social problems, namely the change of political power in the country, instability, the struggle of criminal and mafia structures for power and influence became the trigger mechanisms that produced violence. There are various versions claiming to explain the events of June 2010, as well as to evaluate the actions of official structures during the conflict. Thus, the Uzbek side claimed that the security forces were inactive, ignored the attacks, in turn, the official authorities argued that the conflict was aggravated by unknown, allegedly foreign mercenaries, besides the Kyrgyz side referred to the police’s unwillingness to such events in the first days of the conflict. Therefore, an analysis of the causes of interethnic conflict in Osh will make it possible to identify the main vectors of instability in society, to identify the main actors to which measures of state influence should be directed in order to prevent possible relapses.
