Abstract Asset integrity for oil and gas operations requires reliable chemical information to troubleshoot factors affecting chemical deliverability and performance. Accurate and precise measurement of corrosion inhibitor (CI) concentration in oilfield brine is significant to asset management. However, historically CI residual measurements are extremely problematic due to the surface-active nature of the chemicals which interact with a host of factors that parasitically deplete the CI solution concentration. It is typical to see >100% error on traditional residual measurements especially where dye transfer techniques are concerned. Current methods and sample handling for measuring residuals involves sending samples to a local laboratory for analysis. This time delay can add to the measurement error due to loss of inhibitor species to the sample container or solids that may form in transport. This paper describes the use of a simple, portable, handheld, onsite, nanotechnology-based, residual method to measure CI concentrations in oilfield brines. With more frequent and highly accurate CI residual feedback operators can react to system conditions that threaten to impact asset integrity. Using the CI residual data provided by a rapid, accurate analytical method, operators could extend asset life and prevent failures long before they become critical.

Abstract Accurate and precise monitoring of chemical additives in oilfield brine is an important aspect of oil and gas operations towards corrosion control and flow assurance. Many operators are required to monitor the residual concentrations of chemical additives in production systems at specific locations to monitor and troubleshoot factors affecting chemical deliverability and performance. However, residual measurements are extremely problematic due to many factors, including the surface active nature of the chemicals and high ionic strength of the brine. The error on residual measurements can often be over 100%. Residual measurement typically requires the collection of a water sample, which often needs to be transported to a centralized analytical laboratory. Analytical techniques used to measure residuals are based on several combinations of separation (e.g. chromatography, liquid-liquid extraction, etc.) and detection (e.g. various forms of spectroscopy). However, most of these methods lack portability and require tedious laboratory procedures located off-site. The current paper describes a nanotechnology-enabled Raman spectroscopy method developed and tested for monitoring chemical inhibitor residuals. Development of this technology with handheld instrumentation provides better detection and quantification of chemical additives in the field and reduces time and cost compared to sending samples to off-site laboratories for data collection.

The Australian workplace is currently in a state of evolution, from the physical space workers occupy to a way of working and interacting in which we are constantly connected. Technology is becoming cost-effective, making it more affordable at all workforce levels; businesses are investing in enterprise-grade solutions that are transforming both daily activities and long-term asset management strategies. To continue to drive the safety, productivity and cost improvements that our globally competitive market demands, we need to constantly assess technology solutions from outside the industry and adapt them to enhance our service delivery within the oil and gas industry. One such opportunity is the development and use of smartwatches within major hazard facilities. Through in-field trials, work crews are equipped with smartwatches that monitor health and well-being, alerting the worker if their risk of injury becomes elevated. These wearables also provide employees with efficient and effective accounting of personnel with their location in the case of emergency and provide opportunities for improved communication and productivity outcomes. Billions of dollars have been spent developing Australia’s oil and gas infrastructure. Ongoing operations and maintenance of these assets (and possible future expansions) remain labour intensive. With Australia’s comparatively high labour costs and the remoteness of both offshore and onshore resources, we cannot afford to hold back investment in our human assets, to gain deeper insights and optimise health and performance, as we have done in the case of our operating assets and equipment.

Introduction. The important factors affecting health and performance of young people are the conditions of education, in particular, a comfortable microclimate in the classrooms of higher educational institutions. Materials and methods. In view of the urgency of this problem, an analysis was made of the microclimate parameters of educational organizations of different profiles (Ufa city, the Republic of Bashkortostan). 294 classrooms were studied in 22 buildings of 4 leading universities in Ufa. A total of 3,822 measurements were taken to determine the parameters of the microclimate. The analysis of ionizing radiation in the aerial environment of classrooms. There was performed determination of radon and its affiliated products content. In order to assess the conditions and lifestyle of students of 4 higher educational institutions of the city of Ufa, we conducted an anonymous survey of 1,820 students of I and IV years of education. Results. The average temperature in the classrooms of all universities studied was 23.9±0.09 C. The average relative humidity in all classrooms was 34.2 ± 0.42%. Analysis of ionizing radiation (radon and its daughter products decay) in the aerial environment of the classrooms and sports halls located in the basement determined that the average annual equivalent equilibrium volumetric activity of the radon daughter products (EROA ± Δ222Rn) ranged from 28 ± 14 to 69 ± 34.5 meter, which meets the requirements established by SanPiN. Conclusion. The hygienic assessment of the microclimate parameters of educational institutions of various profile revealed a number of deviations from the regulated norms. The results indicate the need to control the parameters of the microclimate, both from the administration of universities, and from the professors. According to the results of the study, recommendations were prepared for the management of higher educational institutions in Ufa.

Public sector banks have been merged by the government in the last few years. This is the rationale behind conducting this study. The purpose of this article is to determine the factors affecting the performance of public sector banks in India and the interrelationship between bank-specific determinants and performance of public sector banks. In this article, we shall analyse the financial data of all the public sector commercial banks for a period spread across 11 years (2009–2019); Capital adequacy, Assets quality, Management efficiency, Earning, and Liquidity (CAMEL) has been used as a performance determinant; system generalised method of moments (GMM) analysis has been used to find the effect of determinants on the performance measurement of public sector banks; and CCA (canonical correlation analysis) has been used to find the interrelationship between the bank-specific determinants and the performance of public sector banks. The finding has important implications in terms of performance in the banking sector. Certain limitations of this study are: It is based on secondary data. The study only covers the financial aspects and not the non-financial aspects. It is found that the asset quality is negatively related with performance of public sector banks. Liquidity and inflation are inversely related to performance of public sector banks in India. Capital adequacy is positively related with banks’ performance, but inversely related with banks’ interest margin. GDP growth has a significant positive impact on banks’ performance, but inversely related with banks’ interest income. Inflation rate is inversely related with banks’ performance. Banking sector reforms are insignificantly related with banks’ performance.

Determination of fish landing price is important, as the same contributes to the structure, conduct and performance of the fish market in Lake Victoria. Determination of relevant landing price is a gap to console between fishermen, agents (middlemen), processors and the government. The main objective of this study was therefore to examine fish price determination. Specifically, to examine the methods for fish price determination and analyse factors that affect fish landing price in Lake Victoria, a cross-sectional design was employed, and 300 respondents were randomly selected from two district councils, namely, Sengerema and Buchosa. Both qualitative and quantitative data were analysed using descriptive statistics and inferential analysis. Findings show that landing price is determined through formal negotiation with processors, consultation with other traders, informal negotiation with buyers and Beach Management Unit (BMU). The study concluded that these are the common methods used to determine landing prices. Also, distance from fishing to onshore landing centres, market information channels, age and experiences of the fishermen are the factors significantly found affecting landing price. It is recommended that the mechanism for setting up fishery price, fish market structure, fishery information and the formation of fishery regulatory body needs fishery policy and sector reforms that mark the determination of fish landing price.

The goal of this experimental study is to manufacture a bolted GFRP flange connection for composite pipes with high strength and performance. A mould was designed and manufactured, which ensures the quality of the composite materials and controls its surface grade. Based on the ASME Boiler and Pressure Vessel Code, Section X, this GFRP flange was fabricated using biaxial glass fibre braid and polyester resin in a vacuum infusion process. In addition, many experiments were carried out using another mould made of glass to solve process-related issues. Moreover, an investigation was conducted to compare the drilling of the GFRP flange using two types of tools; an Erbauer diamond tile drill bit and a Brad & Spur K10 drill. Six GFRP flanges were manufactured to reach the final product with acceptable quality and performance. The flange was adhesively bonded to a composite pipe after chamfering the end of the pipe. Another type of commercially-available composite flange was used to close the other end of the pipe. Finally, blind flanges were used to close both ends, making the pressure vessel that will be tested under the range of the bolt load and internal pressure.

Formal new product development (NPD) processes have become an important tool in NPD management. However, our understanding of what makes formal NPD process implementation successful in terms of acceptance and performance is still limited. This paper contributes to an improved understanding of factors affecting the acceptance and use of formal NPD processes. Our results show that acceptance of formal NPD processes is determined by several factors, such as ease of use, transparency of discourse, continuous improvement, involvement of NPD actors, and the ability to bridge differences in thinking. Furthermore, that acceptance of formal NPD processes affects NPD performance positively. These results draw on data from a survey posted to employees working for nine large manufacturers of commercial vehicles worldwide. The results should encourage managers to consider and enhance the factors affecting acceptance. This could be done through using new media for publication to increase transparency and perceived ease of use of the NPD process. Further acceptance of the formal NPD process is increased if it mirrors an operative reality and if organisational structures for improvement of the process are implemented and inclusive to employees involved in NPD.

Purpose – Church giving and attendance are two important indicators of church health and performance. In the literature, they are usually understood to be simultaneously determined. The purpose of this paper is to estimate if there a sustainable church congregation size using Wintrobe’s (1998) dictatorship model. The authors want to examine the impact of youth and adult ministry as well. Design/methodology/approach – Using the data collected from among Canadian Baptist churches in Eastern Canada, this study investigates the factors affecting the level of the two indicators by the panel-instrumental variable technique. Applying Wintrobe’s (1998) political economy model on dictatorship, the equilibrium level of worship attendance and giving is predicted. Findings – Through various simulation exercises, the actual church congregation sizes is approximately 50 percent of the predicted value, implying inefficiency and misallocation of church resources. The paper concludes with insights on effective ways church leaders can allocate scarce resources to promote growth within churches. Originality/value – The authors are the only researchers getting the permission from the Atlantic Canada Baptist Convention to use their mega data set on church giving and congregation sizes as per the authors’ knowledge. The authors are also applying a theoretical model on dictatorship to religious/not for profits organizations.
