Effective corrosion monitoring can be achieved using mobile potenciostat through the selection of appropriate monitoring methods and special kind of sensor. Stern polarization technique in non-invasive arrangement was used to monitor OCP potential and actual corrosion rate of pipeline with corrosion products in soil mixture. Using global database with range of minimum and maximum corrosion rate limits obtained from terrain measurements we can determine active or passive role of corrosion products and assess risk joint with aggressiveness of soil in location of interest. Finally, values were divided between high active, medium active and passive corrosion. Output is alarm, which can help in decision if reconstruction of underground pipelines where isolation failure in time is sufficient or not. When done properly, corrosion monitoring using non-invasive in-situ technique can serve as an early warning system before the onset of corrosion-related failures.Fig. 1 Non-invasive corrosion monitoring on underground pipelines

In recent years evolution of Internet of Things has brought revolution in many different sectors.  The agriculture sector has become efficient and cost effective due to role of IoT. Monitoring systems has become the crucial part of agriculture. In past few years lot of work is been done and many systems has been purposed in this regard. In this paper we are going to make comparison between 4 different agriculture monitoring systems. We are also going to discuss what type of hardware including different sensors are used in those systems. We are also going to discuss software and platform on which those applications run. We will also discuss processing mechanism and what kind of algorithms are used in these systems and in the last we are going to make a comparative table based on these parameters.

Integrity Management

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 197168, “Digitalize Asset-Integrity Management by Remote Monitoring,” by Mohamed Sahid, ADNOC, prepared for the 2019 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, 11-14 November. The paper has not been peer reviewed. Monitoring of corrosion in process pipelines has always been of paramount importance in ensuring plant-asset integrity. Similarly, steam traps play an important role in ensuring steam quality and, thus, the integrity of critical assets in the plant. The complete paper discusses these two aspects of monitoring asset integrity - real-time corrosion monitoring and real-time steam-trap monitoring - as implemented by the operator. The authors highlight the importance of digitization by means of implementing wireless technology and making data available in remote work stations in real time. Real-Time Corrosion-Monitoring System Corrosion coupons and electrical resistance probes are among the most-tried and -tested methods to monitor corrosion, but the authors detail shortcomings of these systems, focusing their efforts on the option of using nonintrusive ultrasonic sensors for corrosion monitoring. Fixed ultrasonic thickness (UT) monitoring systems measure a localized thickness of vessel wall or pipe through the use of sound waves. They are the fastest method to measure wall thickness and wall loss reliably. The wall thickness is calculated from the reflection of the ultrasonic signal at both external and internal surfaces. UT systems normally include a transducer and a pulser/receiver. The type of transducer used for this application is the ultrasonic transducer, which can be either piezoelectric or variable-capacitive. The pulser generates short electric pulses of energy at a constant rate, which are converted by the transducer into short, high-frequency ultrasonic sound pulses. These pulses are then directed into the material. Any discontinuation or impurity in the path of the ultrasonic sound wave will be reflected and received by the transducer, transformed into an electric signal, and amplified by the receiver to be projected onto the display (in the case of portable UT instruments). Depending on the intensity shown on the display, information about the impurity or discontinuity, such as size, orientation, and location, can be derived accurately. The shortcomings of using portable UT sensors have been overcome by the introduction of permanent UT sensors, which provide wall-thickness measurement continuously at one location in real time. Because these sensors remain fixed at one location for years, it is possible to analyze corrosion at a single point over time, thus detecting early corrosion onset. Real-Time UT Gauging. The operator installed the real-time corrosion-monitoring system in its offshore associated gas (OAG) unit. A UK-based vendor provided UT sensors along with data-management and -viewing software to support data interpretation. Twenty locations were identified in various plants of the OAG unit on the basis of criticality and previously recorded corrosion levels.

Based on the analysis of scientific resources, the role of educational environment in personal building, development and education is actualized. It is stated that educational environment is one of the most essential factors of those processes. The author’s definitions of notions “educational environment”, “educational environment of institution of higher education” are given. The authors advocate the point that educational environment is a system of facilities for personal education. It is emphasized that the environmental approach in education is changing accents in teaching which is aimed at creating and developing educational environment, which has to meet educational needs of a student. The author’s technique of evaluating the state of educational environment of institution of higher education is grounded and approved, the rating scale of this technique is introduced. The technique suggests making expert evaluation of educational environment of institution of higher education according to qualitative (modality) and quantitative (professional breadth, professional saturation, sociocultural intensity, congruence, openness, mobility, informativeness) parameters. The typology of educational environment of institution of higher education is presented (innovative-professional, formal-professional, pragmatically-oriented, formal general cultural educational environment). The analysis and interpretation of the results obtained from the experiment at University College of Borys Grinchenko Kyiv University are given. The evaluation of educational environment of the college has been made by three groups of experts, which have included students, teachers and parents. Despite the fact that evaluation by different groups of experts are similar, it is revealed that it has essential differences, which has been proved with appropriate statistical methods. It is determined that the substantiation of the whole monitoring system of educational environment of institution of higher education and corresponding diagnostic tools has great potential.

A diabetes mellitus kezelésének ellenőrzésében napjainkban egyre elterjedtebben használt módszer a folyamatos cukormérő rendszer, mely a hagyományos mérések között rejtve maradó vércukor-ingadozásokat rögzíti. Betegek és módszer: A szerzők 53 betegen végzett 79 mérés eredményeit elemzik. A betegek közül 48/53 fő (90,5%) (30 nő, 18 férfi, átlagéletkor 26,3 ± 16,8 év) 1-es típusú, 5/53 fő (9,5%) (4 nő, 1 férfi, átlagéletkor 58,4 ± 6,2 év) 2-es típusú diabetes mellitusban szenvedett. A módszer technikai ismertetését követően a szerzők saját betegeken végzett mérések eredményeit, illetve más vizsgálók tapasztalatait is felhasználva bemutatják a rendszer előnyeit és hátrányait. A szerzők az átlagosan 3–4 napos mérésekhez a MiniMed cég által kifejlesztett eszközt, illetve szenzort használták. Eredmények: Az elvégzett vizsgálatok alapján a módszert elsősorban a hajnali jelenség, valamint az észrevétlen hypoglykaemiák kimutatásában találták leginkább használhatónak, de számos esetben láttak tartós hyperglykaemiás időtartamokat is. A módszer az esetek 64,5%-ában jelentett segítséget a terápiás döntésekben, beszámolnak azonban szenzorhibából adódó sikertelen mérésekről, illetve olyan esetekről, amikor a vizsgálat elvégzése után sem tudtak érdemi terápiás változtatást javasolni. Megbeszélés: A szerzők – a saját eredmények, valamint más vizsgálók tapasztalatai alapján – széles körű indikációs listát vázolnak fel, bemutatva a módszer alkalmazhatóságának területeit, valamint korlátait. Kiemelik, hogy 2-es típusú diabéteszes betegek esetében nem nyújt érdemi segítséget. Az eredmények bemutatásával fontosnak tartották hangsúlyozni, hogy a módszerrel a hagyományos mérésekhez képest olyan többletinformációkhoz lehet jutni 1-es típusú diabéteszes betegek esetén, melyek segítségével e betegek glykaemiás kontrollja, ezáltal életkilátása javítható.
