Коррупция и государство в Сахеле

Начиная с 2000 гг. новые инструменты оценки борьбы с коррупцией создают нелестный образ госу-дарств Сахеля. Согласно наиболее известному из них – Списку стран по восприятию коррупции (Corruption Perception Index, CPI), составляемому международной неправительственной организацией Transparency International, в 2016 г. практически все страны региона попали в группу государств с эндемической коррупцией. Однако восприятие коррупции внутри группы варьирует: Сенегал и Буркина Фасо считаются менее коррумпированными, чем Мали и Нигер, которые, в свою очередь, вы-глядят лучше Мавритании и особенно Чада, входящего в список 20 наиболее коррумпированных стран мира – вместе с Бурунди, Гаити, Центральноафриканской Республикой и Демократической Республи-кой Конго. Однако эти чисто количественные и вырванные из контекста измерения проливают мало света на социальное и культурное обрамление повседневной коррупции. Настоящая статья опирается на качественные эмпирические полевые исследования, ведущиеся автором в Нигере, Сенегале и Мавритании. Starting in the early 2000s, new means of measurement produced by the international anticorruption indus-try cast a rather unflattering light on the Sahelian countries, stigmatizing them for their lack of public integ-rity. In 2016 the best known of these tools, Transparency International’s “Corruption Perception Index” ranked all Sahelian countries, excepting (barely) Senegal, as states with systemic corruption (a score lower than 43). Perceptions vary from country to country: Senegal and Burkina Faso are reputedly less corrupt than Mali and Niger; these two are, in turn, more virtuous than Mauritania, and even more so than Chad. These approaches, purely quantitative and decontextualized, shed little light on how corruption is socially and culturally embedded in everyday life. In contrast, this article is based on qualitative empirical studies and on the author’s own research in Niger, Senegal, and Mauritania.

Various Methods for Measurement of Resistive Leakage Current of Metal Oxide Surge Arrester

Metal Oxide Surge Arrester (MOSA) does not require any ordinary maintenance. But MOSA is get affected from ageing due to the effect of discharging impulse currents, uneven heating and internal partial discharges. A leading cause of deterioration is ingress of moisture. The degradation of MOSA also correlated with the ageing level of the arrester. This is called degradation under surge. The ageing level with the degradation of MO surge arrester or the leakage current of the surge arrester is related to each other. The leakage current is directly proportional to the ageing level. If the ageing level is raise, the leakage current also will increase. So, various methods for determination of the condition of ZnO surge arrester by means of measurement of the arrester leakage current are discussed. A MSCM method, which is based on leakage current of the surge arrester presented. The measuring instrument Leakage Current Monitor is also discussed.

CONSIDERATIONS ON ALGORITHMS OF SELECTION AND COMPONENTS FORMING OF ON-BOARD INFORMATION AND MEASURING COMPLEXES AND REGISTRATION SYSTEMS. PECULIARITIES OF THEIR APPLICATION

On-board information and measuring complexes and registration systems are intended to control the parameters of both systems and components of the prototype and the sample of automotive and armored vehicles in general to obtain qualitative and quantitative characteristics to assess their compliance with specifications of technical development requirements. At present stage, there is often a need to improve methods for optimizing the development of on-board systems for collecting and processing information to ensure conducting of testing works, which take into account particulars of the electronic equipment development and are based on a unified approach to the optimal use of resources of collection and information processing systems. Analysis of the problem of rational use of resources of standard means of measurement, registration and indication in the system of onboard measurements and further processing of the results in automated systems for collecting and processing information for their use in testing mass produced (modernized) aircraft was previously considered by Soviet, Ukrainian and foreign scientists. But they do not give a complete picture of the algorithm, completeness and quality of tests using standard measuring instruments installed on board aircraft and do not answer a number of questions related to the optimization of the computational process. In particular, the potentials of standard means of measurement, registration and indication as part of the on- board measurement system for testing mass produced (modernized) aircraft and installed components, units and systems under test are not fully explored. The issue of building optimal data collection programs that implement the inquiry of measuring channels with restrictions on the frequency of channel inquiry and information processing speed is insufficiently studied. The novelty of the research consists in the developing of an algorithm for capabilities analysis and procedure for incorporating standard measuring, registration and indication instruments in the on-board measuring system within a single measuring and information field for testing mass produced (modernized) samples of weapons. Approbation and implementation of the abovementioned algorithms will allow test teams to minimize time spent on the development (selection) of the onboard measurement system to ensure research and testing of both modernized aircraft, vehicles and armored vehicles and newly created with advanced information systems.

THE MEASURING CHANNELS CALIBRATION IN THE INDUSTRY

The trend of development of measuring equipment in particular measuring systems and technological processes leads to the need of measuring the temperature without dismantling the primary transducers and stopping the technological process in a very wide range and with high accuracy. The choice of methods and means of measurement depends on such factors as the value of measured temperature, necessary accuracy of measurement, conditions of measurements, and operation of the investigated object. The topicality of the problem is that industrial metrology operates the temperature measuring systems, transducers of which are deployed in such a way that their dismantling is impossible due to the specifics of the process or dangerous for operators’ life (nuclear power plants). Such measuring systems, due to the specifics of their application, are not metrologically provided in the periods between major repairs of controlled objects, thus violating the unity of measurements.

Verification of Gas Flow Traceability from 0.1 sccm to 1 sccm Using a Piston Gauge

Fluke Calibration is accredited for gas flow measurements in the range of 0.1 sccm to 6000 slm in nitrogen and air. Traceability is maintained directly through a gravimetric f low standard but only recently from 1 sccm to 10 sccm. The traceability of flow in the range of 0.1 sccm to 1 sccm is based on extrapolation of the use of laminar flow elements (LFE) below 1 sccm. This part of the range has never been completely verified through interlaboratory comparisons, proficiency testing or other means of measurement assurance. In an internal document from DH Instruments in the early 1990s it was suggested that a piston gauge might improve traceability for very low gas flows. In order to prove out traceability in this range an attempt was made to use a piston gauge using a piston-cylinder size of 35 mm diameter as a reference. One reason for choosing a piston gauge as a reference is its pressure control. This is crucial when measuring gas flow through a LFE in this design and range. In addition, the effective area is known to within 0.001 %, leaving the vertical displacement of the piston to dominate the uncertainty of the dimensional part of the flow test. This was a challenge because the measurements required absolute mode and the internal piston position sensor supplied with the piston gauge did not have sufficient precision. This paper describes the theory and design of the gas flow measurement system, the current results, and improvements desired or suggested. Two different designs are discussed, one with a single piston gauge as a reference and one with two piston gauges measuring flow on either side of the laminar flow element. Note: sccm (standard cubic centimeters per minute) is an industry accepted alternative to kg/s [1]. It is used out of convenience to normalize flow rates of gases with significant differences in density.
