The increasing size and complexity of natural gas transmission and distribution systems in North America are leading to higher dependence on automated, remote communication and monitoring of meter station, compression, and pipeline facilities. Along with implementing new technology comes the need to maximise operating cost efficiencies while continuing to deliver reliable transportation service. Managing alarm conditions at over 1100 receipt and delivery meter stations in an efficient and effective manner has become increasingly important for NOVA Gas Transmission Ltd. (NGTL) to satisfy customer requirements for finalising individual gas accounts on a daily basis. As a result, NGTL has developed a “Meter Station Alarm Management Plan”. This paper describes the process developed and implemented by NGTL in categorising and prioritising measurement alarms and providing the right response, along with the benefits to be achieved.

Abstract Multistage fracturing (MSF) ball drop completion systems have been utilized around the globe for effectively treating formations completed as open hole and cemented. Multiple, high-rate hydraulic fracturing stages are pumped through these completions while gaining efficiency during pumping operations. A challenge within the industry was developing systems that are capable of higher pressures (greater than 10k psi) while still being able to be deployed in challenging openhole environments with minimum equipment and intervention requirements. This paper will discuss the planning, deployment and fracturing execution operations of an improved version of one of these systems. To be able to effectively utilize any MSF completion system; formation properties, deployment environment, lateral length, openhole size, liner size, and tubing movements during fracturing should be thoroughly analyzed and equally considered. To create a reliable system, another important consideration is how the system will be deployed; a long string to surface, or will it be deployed as part of a liner hanger system? In the case of the latter, it should be compatible with the liner hanger system by accommodating multiple balls to set and release the hanger system and actuate the openhole packers. In tight formation environments, where treating pressure differentials reaches as high as 15,000 psi during fracturing operations, openhole packers that are capable of holding these pressures in challenging openhole conditions are needed. Not only the packers but also the remaining completion system components need to be capable of withstanding, including burst, collapse, and ball-to-ball seat differential while simultaneously accommodating the pressure with cooling and ballooning induced tubing movement caused by these high pressure treatments. Improving such a robust design with innovative solutions, such as dissolvable frac balls that can handle 15,000 psi differential, optimizes the overall process. The completion design, deployment, and subsequent fracturing operations on a well showcases how effective consideration of components operates as a system can create a reliable MSF system. It also demonstrates how close collaboration between reservoir management, production engineering, completion experts, and vendor results in a coordination of efforts that eliminates operational hazards, thus ensuring smooth operations. The successful deployment of an openhole MSF completion system that can handle 15,000 psi with dissolving frac balls and eliminating openhole anchors helped pave the way to deal with tighter formations in an efficient and cost-effective manner. With the help of this new technology, the well planners were able to address operational challenges that would have otherwise required additional equipment or would have limited deployment capabilities. The engineering approach and design to develop this completion system and utilization in the right candidate confirmed the benefit of the novel completion for field development options.

Background:Telemedicine counseling (TMC) has gained rapid development during the COVID-19 pandemic. The prospect of using this technology in rheumatology was based on the possibility of getting maximum information about the patient during the survey, examination and interpretation of laboratory and instrumental data, that is excepting direct contact with the patient. Several rheumatological clinics have reported on the success of using TMC. However, there is very little data of the difficulties that can be encountered when organizing this process.Objectives:To characterize the identified problems during TMC in rheumatology, to suggest potential directions for their elimination.Methods:Since June 2021, on the basis of the Medical Association “New Hospital”, Yekaterinburg, Russian Federation, 76 TMCs have been performed on the profile of rheumatology in patients aged 29 to 71 years. Of these, 13 applied to the primary TMC, the other patients were preliminarily examined in person. The consultation included the preliminary acquaintance with the examination results, a 20-minute video communication and writing of a conclusion. After each TMC, a survey was conducted between the doctor and the patient, including the identified deficiencies in counseling. The frequency of identified problems is presented as an absolute indicator and as a percentage of the total number of TMCs performed.Results:We noted a high degree of patient satisfaction: 74 (97.4%) responded that they received answers to all. However, according to the doctor, the following groups of problems were identified.[1]Technical problems in 29 (38.2%): most often there were various problems with the Internet, but there were also registered: the end of the charge on the patient’s tablet, the patient was not registered in the electronic queue. Elimination of these violations depends on the work of IT-specialists, but each consulting physician should be prepared for an immediate transition to an alternative form of communication (for example - telephone).[2]Lack of objective examination, leading to the impossibility of correct remote diagnosis - 8 (10.5%). This problem was identified due to the inability to establish the presence or absence of arthritis during the initial diagnosis (6 cases) and to clarify the nature of the rash (2 cases). All patients are invited for a face-to-face consultation.[3]The need to write prescriptions for psychotropic drugs - 12 (15.8%), which under the conditions of national legislation cannot be done in the TMC regime.[4]The time spent directly on remote communication with the patient was 17.2 minutes (from 8 to 31), however, taking into account the study data and writing the conclusion, the total time was 40.7 minutes (from 21 to 73). Thus, it turned out that the average time for remote and face-to-face consultations is the same, while TMC’s payment is only about 50% of the face-to-face consultation. This situation reduces the doctor’s interest in carrying out TMC. The solution to the problem is associated with reducing the time for the documentation process through technical improvements. In addition, of the 9 patients in whom the TMC process lasted 60 minutes or more, 5 were diagnosed with fibromyalgia. It is possible that with a previously established diagnosis of fibromyalgia, only face-to-face counseling should be recommended to patients.Conclusion:The TMC system is promising, however, there are a number of problems that need to be improved, since they can reduce the doctor’s interest in using this technology.Disclosure of Interests:None declared

A new design parameter, friction-instability, is defined in this paper. Friction-instability is a variation in the coefficient of friction which may occur at any time during the life of a brake lining. A friction-index is defined which measures this variation. A lining which has a high friction index may tend to cause an automobile to swerve either to the right or to the left. A unique experimental facility is described by means of which the friction-instability characteristics of brake linings can be measured. Test results using this facility are presented and interpreted. The friction-index is proposed as a new parameter which should be taken into consideration when brakes are designed and, developed. This index should be particularly useful as a quality control device to insure that machines which use mass-produced braking systems will perform in a safe and effective manner.

In the study we present results of two research projects conducted simultaneously at the Faculty of Social Sciences, UWM in Olsztyn referring to the place digital technologies have in the learning processes in the opinions of Early Education students. The results show that the group of surveyed students might be situated on the borderline of digital natives and digital immigrants’ worlds. The conducted survey demonstrated limited trust to digital sources of knowledge amongst students and discrepancy between their personal experiences with using new technology, on a daily basis, and traditional ways of learning proposed by the University. The analysis of the case study indicated that for preparing future teachers to work with children (digital natives), it is important to organize a learning environment in which both worlds – digital and analogue – are connected.

Will the internet, robotics and artificial intelligence mean a ‘jobless future’? A recent narrative, endorsed by prominent tech-billionaires, says we face mass unemployment, and we need a basic income. In contrast, this article shows why the law can achieve full employment with fair incomes, and holidays with pay. Universal human rights, including the right to ‘share in scientific advancement and its benefits’, set the proper guiding principles. Three distinct views of the causes of unemployment are that it is a ‘natural’ phenomenon, that technology may propel it, or that it is social and legal choice: to let capital owners restrict investment in jobs. Only the third view has any credible evidence to support it. Technology may create redundancies, but unemployment is an entirely social phenomenon. After World War Two, 42% of UK jobs were redundant but social policy maintained full employment, and it can be done again. This said, transition to new technology, when markets are left alone, can be exceedingly slow: a staggering 88% of American horses lost their jobs after the Model T Ford, but only over 45 years. Taking lessons from history, it is clear that unemployment is driven by inequality of wealth and of votes in the economy. To uphold human rights, governments should reprogramme the law, for full employment, fair incomes and reduced working time, on a living planet. Robot owners will not automate your job away, if we defend economic democracy.

The objective of this work was to evaluate the production costs and profitability indexes of sorghum crop for silage production under different irrigation depths. The work was conducted at the Federal Institute of Education, Science and Technology of Ceará (IFCE) – Umirim Campus, from September to December 2016. The treatments were arranged in 5 x 5 split plots with 5 replications. Irrigations were performed on a daily basis, and the applied depths were calculated based on crop evapotranspiration (ETc). The primary treatments were 50, 75, 100, 125 and 150% of ETc, associated with different levels of carnauba bagana mulch (0.00, 2.50, 3.75, 5.00, and 6.25 cm). Effective Operating Cost (EOC), Total Operating Cost (TOC), Gross Revenue (GR), Operating Profit (OP), Profitability Index (PI) and Break-Even Price (BEP) were estimated. According to the indicators analyzed, it was found that this is a promising crop within the different agricultural production schools, with favorable rates for the producer. The variety evaluated presents high resistance as to the water limitation factor, showing positive indicators such as break-even point below the average prices practiced in the region.

Abstract Indonesia has ratified the United Convention Law of the Sea of 1982 with the Law No. 17 of 1985 concerning the Ratification of United Nations Convention on The Law of the Sea 1982. It means that Indonesia has the right to use, conserve, and manage fish resources in the Indonesia’s Exclusive Economic Zone (IEEZ). To guarantee the optimal and sustainable management of Indonesian fish resources, the role of fishery supervisors and community participation in an efficient and effective manner is needed. Law enforcement in the field of fisheries is very important and strategic to support fishery development in accordance with the principle of fishery management, so that the sustainable development of fisheries can be done continuously. Therefore, the existence of legal certainty is absolutely necessary to support fishery management in Indonesia.
