Quenching Process

AISI 8640 is one of the most used steel in the manufacturing industry due its wide range of applicability and properties. The quenching process is commonly applied in parts made of this steel in order to enhance some properties, such as strength and hardness. Petroleum derived oils are the most common quenchants, however this kind of quenchant is considered to be non-biodegradable, toxic to the health and environment, as well as, not renewable. In the present study, canola oil presented the same efficiency than a conventional petroleum derived oil in the quenching process of AISI 8640 steel billets with diameter of 25.4mm.

In many industrial sectors, the use of RFID in closed systems is evolving. To be implemented in global supply chains, all aspects related to RFID need to be standardised. By collecting, processing and distributing information efficiently, organisations should be able to improve the efficiency of their transport logistics processes, lower their operational costs, and improve their portfolio of logistics services. This case study describes the current perspectives, challenges and benefits of RFID applications in manufacturing industry. Automated, remote and wireless identification is a basic element in implementing efficient management systems in the supply chain. The most important identification techniques are barcode and RFID. Barcode is currently the most widely used method for the identification of parcels, but RFID is more suitable for automated identification for many different reasons including better readability and enhanced environmental durability. By reducing manual work and errors, RFID generates cost savings, increased productivity and efficiency of processes. There is a wide range of different RFID technologies that have varying reading ranges, protocols and data contents. There are two different approaches to using RFID tags and numbering the items to be identified. Recent standardisation developments have started to resolve the interoperability problems in the field of RFID identification.

Abstract Although many literature reviews synthesize literature regarding workplace health promotion (WHP) interventions, systematic reviews on the effectiveness of and factors influencing the operation of WHP activities in low- and middle-income countries (LMIC) are scarce. Therefore, we systematically reviewed evaluation studies to examine the effectiveness and factors related to the implementation of WHP programmes in LMIC. Twenty-six peer-reviewed and grey evaluation studies, published before November 2017, were included from electronic databases (PubMed, The Cochrane Library, PsycINFO, EMBASE and Web of Science) and manual searching. The results revealed that WHP intervention in LMIC was effective in reducing health risks in a wide range of industries and settings, including in resource-poor contexts such as small enterprises and the manufacturing industry. The main factors positively influencing the effectiveness of the intervention are long intervention time period, and needs-based and active intervention strategies. In addition, commitment from workplace leaders, the involvement of workers and support from authorities and professionals are factors contributing to a successful WHP programme. However, the evidence regarding the effectiveness of WHP in LMIC regarding the health outcomes and business productivity is inconclusive due to the several remaining methodological limitations. Future developments of more rigorous methods of evaluating the effectiveness of WHP activities should be addressed to produce higher-quality evidence that would inform future practice.

Abstract Rotary seals are found in many manufacturing equipment and machines used for various applications under a wide range of operating conditions. Rotary seal failure can be catastrophic and can lead to costly downtime and large expenses; so it is extremely important to assess the degradation of rotary seal to avoid fatal breakdown of machineries. Physics-based rotary seal prognostics require direct estimation of different physical parameters to assess the degradation of seals. Data-driven prognostics utilizing sensor technology and computational capabilities can aid in the in-direct estimation of rotary seals’ running condition unlike the physics-based approach. An important aspect of data-driven prognostics is to collect appropriate data in order to reduce the cost and time associated with the data collection, storage and computation. Seals in machineries operate in harsh conditions, especially in the oil field, seals are exposed to harsh environment and aggressive fluids which gradually reduces the elastic modulus and hardness of seals, resulting in lower friction torque and excessive leakage. Therefore, in this study we implement a data-driven prognostics approach which utilizes friction torque and leakage signals along with Multilayer Perceptron as a classifier to compare the performance of the two metrics in classifying the running condition of rotary seals. Friction torque was found to have a better performance than leakage in terms of differentiating the running condition of rotary seals throughout its service life. Although this approach was designed for seals in oil and gas industry, this approach can be implemented in any manufacturing industry with similar applications.

Innovation Support

We evaluate the effect of innovation support programs on output innovation by small and medium enterprises in traditional manufacturing industry. This focus is motivated by a definition of traditional manufacturing industry that includes capacity for innovation, and by evidence of its continued importance in European Union employment. We conducted a survey in seven European Union regions to generate the data needed to estimate pre-published switching models by means of the copula approach, from which we derived treatment effects on a wide range of innovation outputs. We find that for participants the estimated effects of innovation support programs are positive, typically increasing the probability of innovation and of its commercial success by around 15%. Yet, we also find that a greater return on public investment could have been secured by supporting firms chosen at random from the population of innovating traditional sector small and medium enterprises. These findings indicate the effectiveness of innovation support programs while suggesting reform of their selection procedures.

Among all the regions of the world, Latin America has been the most vulnerable to the spread of the coronavirus epidemic. The COVID-19 pandemic not only exposed the weaknesses of national health systems, but also served as a catalyst for the crisis socio-economic phenomena that have developed in the region over the past decade. The impact of the pandemic should serve Latin America as a clear lesson and motivate the local political and business establishment to make a significant adjustment to the content of the regional development strategy. It is logical, in our opinion, to raise the question of rethinking the role of the state in public life, the development of a modern, meeting the requirements of the moment, the Latin American concept of epidemiological and socio-economic security. In the post-covid period, at the center of public attention and targeted government efforts ought to be the challenges of radically improving health care through the priority development of those sectors of the economy that can provide diversification and, as a result, increase the level of crisis-sustainability of Latin American states. First of all, they should focus on the manufacturing industry, including the production of a wide range of medicines and equipment, as well as the sectors that ensure the development and modernization of socio-economic infrastructure: utilities, transport, alternative energy, telecommunications. In the field of international relations, the importance of cooperation with those States that have pioneered the development of COVID-19 coronavirus vaccines has increased significantly. In this context, it must be mentioned the interest that the registration in the Russian Federation of the first domestic vaccine Sputnik V provoked in Latin America.

The Way

SynopsisThis paper gives ‘an insider's view’ of the Scottish processed food manufacturing industry, through the eyes of the Managing Director and Chairman of a distinctive family company sited midway between Aberdeen and Inverness on the banks of the River Spey.In 1946 the company employed a mere 11 people, and manufactured only preserves and beetroot products, having an annual sales value of £40,000. Today a wide range of products is sold in over 60 countries with an annual turnover approaching £20 million and a profit of £1–5 million.Forty years ago there were more than 20 jam making companies in Scotland; and in the United Kingdom more than 30 manufacturers of canned soups. Today there are only 5 of the former category and 5 of the latter making and selling their own brands. What has happened in these 40 years? Some answers are given to that question and an outline of the way ahead is presented.
