Changes in management of the heat-supplying organizations of the modern city determined by development of technologies in this sphere are considered in the article. Three groups of technologies are allocated, the priority of the auxiliary technologies considered is given. The author points out that there is the need of the information support of management of the heating systems management in the city, which need fundamental reconsideration and radical redesign. The additional argument of the need of reengineering of the heat supplying organizations management is the consideration of the results of their activity, connected with considerable thermal losses. The key provisions of the offered measures for reengineering, based on the creation of processes of information support of management "from scratch" are described. Negative changes of the performance of the heating systems of concrete types were estimated q, and thanks to that the new integrated approach to the choice of methods and technical means of diagnostics of engineering systems and analytical dependences of determination of terms of repair were offered. Obtaining of qualitatively new information through reengineering measures for making managerial decisions is considered. Scenarios of prospects of energy industry, which have been differentiated as the most realistic or connected with the risk of increase in the stubborn problems, minimized by reengineering, were analyzed.

Theory and practice of tourism logistics in the logistics of services structure are opened. Essence of logistical integrated strategy of sustainable development of urban tourism, based on two concepts - tourism decentralization and reverse logistics is outlined. The first concept is based on logistical organization of the tourist space of the city, which includes such components as: geologistical (geographical and logistical) identification of the resource base of urban tourism; logistical planning of tourist flows and determination of their needs; logistical design of tourist infrastructure; logistical design of supply chains of tourist infrastructure. The second concept involves an integrated approach to the recycling of the total amount of urban waste, including tourist one, taking into account their collection and removal from the city, as well as processing at special enterprises. The experience of Ukrainian cities of Lviv and Kyiv in this context is considered.

Methods for determining the effective heating radius (EHR) in district heating systems (DHS) are developed, taking into account ensuring of reliable heat supply to consumers. EHR is such a length (distance) of a heat network (HN) from a district heat source (HS) to a consumer, within which the district heat supply of a given consumer is economically more profitable than a distributed (autonomic) one. Thus, the search for EHR for different transmission heat pipelines (TP) connected to the considered HS determines of its operation zones in different districts of the city. In addition, to the main problem of the EHR search, the assessment of nodal reliability indices (RI) for each consumer is carried out, on the basis of which the obtained EHR solutions are corrected (if necessary). As a result, we can determine the zones of district heating in DHS, within the framework of which not only energy and economically effective, but also reliable heat supply to consumers is provided. The developed methodical ensuring was used in the development of an optimal heat supply scheme for the Irkutsk city (Eastern Siberia, Russia). The brief review on the results of the conducted practical researches case study is presented.

The article considers the issues related to the identification and establishing of economically sound criteria to assess the effectiveness of control processes in the modern context, as well as defines the characteristics of the new assessment format to address its main target, which is providing information support of development and making managerial decisions. The authors determine that the main problem, when assessing the effectiveness of control processes lies in the fact that many of the developments offered by specialists are based on outdated principles, while others put forward proposals, which cannot be used in practice. The authors offer their own vision of the content and functioning specifics of the intracorporate control services, as well as offer a flowchart reflecting control actions of specialists of institutional and intracorporate control services of companies with public ownership. The regulation on the quality assessment system of intracorporate control of the corporate accounting and control system is proposed, as well as the managerial actions in relation to its organization are defined. A new concept of intracorporate control in companies with public ownership, developed by the authors, focused on risks, will prevent misuse of budget allocations. Implementation of the proposals will allow developing science-grounded intracorporate control regulations, which are aimed at solving specific problems of corporate management

Imaging energy filters can add new information to electron microscopic images with respect to energy-axis, so-called electron spectroscopic imaging (ESI). Recently, many good results have been reported using this imaging technique. ESI also allows high-contrast observation of unstained biological samples, becoming a trend of the field of morphology. We manufactured a new type of energy filter as a trial production. This energy filter consists of two magnets, and we call γ-filter since the trajectory of electrons shows ‘γ’-shape inside the filter. We evaluated the new energyγ-filter TEM with the γ-filter.Figure 1 shows schematic view of the electron optics of the γ-type energy filter. For the determination of the electron-optics of the γ-type energy filter, we used the TRIO (Third Order Ion Optics) program which has been developed for the design of high resolution mass spectrometers. The TRIO takes the extended fringing fields (EFF) into consideration. EFF makes it difficult to design magnetic energy filters with magnetic sector fields.

<p>Some areas in the city of Bandung is an area that dilitasi by the flow of the river, to prevent the introduction of garbage into the river basin is necessary to note the waste management systems in residential areas along the river. Cidurian river has a length of 24.86 Km along the river flow. Consists of the city of Bandung and Bandung regency. Administrative regions Cidurian River past eight (8) districts, from the region in the District Kiaracondong precisely Village Babakan Babakan Sari and Surabaya populous and the most densely populated. Thus, there should be community-based waste management in the form of a reduction in resources to prevent potential entry of waste into the river basin. Planning waste reduction will be divided into two, namely the reduction of inorganic waste with waste bank then the reduction of organic waste with absorption holes biopori, and bio reactor mini determination of the reduction is determined by the results of the analysis of the sampling covers the composition and garbage, then the result of the measurement characteristics test and analysis results questionnaire.</p>

Широкое распространение безнадзорных животных на территории городов несет за собой потенциальную угрозу распространения зооантропонозных заболеваний, одним из которых является демодекоз. Невозможно разработать мероприятия, направленные на борьбу с заболеванием и его профилактику, без анализа данных особенностей возникновения и распространения инвазии среди всей популяции восприимчивых животных. Поэтому целью нашей работы явилось изучение распространения демодекоза среди безнадзорных собак и кошек в городе Тюмени. В задачи исследования входило изучение распространения демодекоза и его клинического проявления среди бездомных собак и кошек в условиях города Тюмени и определение сезонной динамики заболевания. Работу выполняли в 2016-2018 гг. на базе кафедры анатомии и физиологии ФГБОУ ВО ГАУ Северного Зауралья, в лаборатории акарологии ВНИИВЭА – филиала ТюмНЦ СО РАН, а также в производственных условиях на базе пункта временного содержания безнадзорных домашних животных МКУ «ЛесПаркХоз». Демодекозная инвазия распространена среди бездомных кошек и собак. Наиболее часто демодекоз встречается у собак, экстенсивность инвазии от 0,65 до 0,72%. Заболевание демодекозом у бездомных собак регистрировали на протяжении всего года, но 54,6% больных собак поступали в апреле и мае. Большинство больных демодекозом – это молодые собаки в возрасте от 1,5 месяцев до 2-х лет – 75,76%, животные старше двух лет гораздо реже страдали от демодекоза – 24,24%. Генерализацию демодекоза регистрировали у 21 собаки (63,64%), а локализованные очаги – у 12 собак (36,36%). Наиболее распространенной формой проявления демодекоза у бездомных собак является пустулезная, или пиодемодекоз. Данная форма заболевания была отмечена у 16 собак (48,49%), чешуйчатая форма отмечалась у 10 собак (30,30%), а смешанная – у 7 собак (21,21%). The widespread use of stray animals in urban areas carries with it the potential threat of the spread of zooanthroponotic diseases, one of which is demodicosis. It is impossible to develop measures aimed at combating the disease and its prevention without analyzing the data on the characteristics of the occurrence and spread of invasion among the entire population of susceptible animals. Therefore, the purpose of our work was to study the distribution of demodicosis among street dogs and cats in the city of Tyumen. The objectives of the study included the study of the spread of demodicosis and its clinical manifestation among stray dogs and cats in the conditions of the city of Tyumen and the determination of the seasonal dynamics of the disease. Demodectic invasion is common among stray cats and dogs. Most often, demodicosis occurs in dogs, with extensive invasion from 0.65 to 0.72%. Demodecosis in stray dogs was recorded throughout the year, but 54.6% of sick dogs were reported in April and May. The majority of patients with demodicosis are young dogs between the ages of 1.5 months and 2 years old - 75.76%, animals older than two years suffer less from demodicosis, only 24.24%. Generalization of demodicosis was recorded in 21 dogs (63.64%), and localized foci in 12 dogs (36.36%). The most common form of demodicosis in stray dogs is pustular or pyodemodecosis. This form of the disease was observed in 16 dogs (48.49%), scaly form, was observed in 10 dogs (30.30%), and mixed in 7 dogs (21.21%).
