The purpose of this study is to evaluate the nutritional effects in Wistar rats of supplementation with stand-alone saturated fatty acid (SFA) or monounsaturated fatty acid (MUFA), the replacement of SFA by MUFA and the combination of both (SFA + MUFA) over a long period of time (13 weeks).

In total, 30 Wistar rats were used and randomly assigned to receive (n = 6): control – lab chow; lard (L20%) – lab chow with added lard (20%); olive oil (O20%) – lab chow with added olive oil (20%); lard replacement with olive oil (L20% –O20%) – during six weeks lab chow with added lard (20%) replaced by lab chow with added olive oil (20%) given during the past seven weeks of the trial; lard combination with olive oil (L10% + O10%) – lab chow with added lard (10%) and olive oil (10%). Food and caloric intake, weight gain, food and energy efficiency, body mass index, bone mineral composition and blood biochemistry were evaluated.

All diets with added fatty acids showed higher energy intake (p < 0.001), weight gain (p = 0.01), accumulation of adipose tissue (p = 0.02) and food and energy efficiency (p = 0.01) compared to the control group. All groups exhibited higher levels of blood triglycerides compared to the control group (p = 0.02). In addition, the L10% + O10% group developed hyperglycemia (p < 0.001); the L group showed higher amounts of non- high density lipoprotein (HDL-c) (p = 0.04); and the L20%−O20% group exhibited high levels of the triglyceride/HDL-c ratio (p = 0.04) in relation to the control.

These results indicate that regardless of the fatty acid type, consumption in large quantities of fatty acids for long periods of time can cause obesity and dyslipidemia.

An understanding of JIT is needed before a successful strategy can be developed. Reading, discussion and evaluation of experience are the starting‐points. A total JIT framework can then be developed and individual elements identified and defined. An integrated socio‐technical approach secures numerous benefits from successful implementation. People are the integrators and facilitators. An implementation analysis technique is proposed with actual results recorded. A pilot installation improves the prospect of success. The text draws on the experience of the writer during the development of JIT at Cummins Engine Company.

If a bearing is carefully handled and correctly mounted, efficiently sealed and properly lubricated, then every cause of damage except one—fatigue— is eliminated. Thus the life of an individual bearing is defined as the number of revolutions that the bearing can make without signs of fatigue damage appearing on any of the rolling surfaces.

WHEN a rolling bearing is damaged as a result of fatigue, spalling occurs cither on the ring tracks or on the surface of rolling elements. As a roller or a ball rolls over these spalls, which are depressions in the surfaces of the rings also known as flaking, impacts occur.

Given the critical consequences of the current Coronavirus (COVID-19) crisis worldwide, displaying good leadership has been of utmost importance. Hospitality has been among the industries that have been hit the hardest by the pandemic, and it requires exceptional leadership skills unique to this crisis and sector. This multi-country study aims to contribute to the understanding of some of the most important skills and strategies that leaders in the hospitality industry may use to navigate the COVID-19 crisis effectively.

This paper employs a qualitative study. Semi-structured interviews are conducted with managers of international hospitality groups or local hotel chains in seven different countries.

The results show that positive thinking, decision-making, flexibility, divergent thinking, trust-building and communication skills have a positive impact on leadership effectiveness in the hospitality sector during the pandemic. Besides, saving payroll costs, elaborating contingency plans and leveraging from partners' strengths are highlighted as crucial strategies.

This paper provides hospitality professionals across borders preliminary insights and recommendations to manage the COVID-19 crisis.

Especially being one of the sectors that have been hit the hardest by the COVID-19 crisis worldwide, the dynamics and leadership requirements of the hospitality sector need further attention. The findings contribute to the literature by illustrating how managers have navigated the initial stages of the crisis in the under-researched hotel sector, and also by gathering evidence about the sector dynamics related to the early stages of this crisis.

SELECTION of the most suitable bearing type for a particular duty can pose a difficult problem due to the wide range of bearings available. To assist the designer these notes describe the more‐frequently‐used types of ball and roller bearings and their components, and refer to some of their uses and limitations.

Flight Operational Noise Internationally, noise due to flight operations in the vicinity of airports. Each nation has developed an individual system of assessment and criteria for judging acceptability or probable extents of annoyance arising from the community based on local conditions and experience.

A NEWLY patented measuring method for detecting damage in ball and roller bearings used in machinery and transport equipment at an early stage was announced and demonstrated at a press conference in Stockholm recently by the SKF Group. The bearings are inspected in operation using the SKF shock pulse meter MEPA 10A which is to be sold by SKF.

This article aims to identify and analyze the factors influencing lecturers’ need to develop their competencies in the field of Library and Information Science (LIS), with a specific focus on the University of Social Sciences and Humanities, Vietnam National University – Ho Chi Minh City (USSH, VNU-HCM).

The study employs an interview method to collect data from lecturers on LIS at USSH, VNU-HCM. Interviews were transcribed verbatim and analyzed according to the qualitative methodology of content analysis.

The results indicate that individual, organizational, disciplinary and professional factors significantly impact the competence development of LIS lecturers. Detailed information about the components of each factor, particularly the roles of professional awareness, career goals, motivation and time management skills is also provided.

This article is limited by a restricted interview participant pool and a sole focus on one university. The study recommends expanding the inclusion of participants to ensure a more diverse perspective and enhance the applicability of the findings.

The research findings offer valuable insights for designing policies, training programs and work environments for lecturers within educational and training institutions in the LIS field.

This study provides a fresh perspective on the challenges and opportunities for developing human resources in the LIS sector in Vietnam.

Lean and agile are essential supply chain management (SCM) strategies that enhance companies' performance. Previous studies have reported the capabilities of different SCM strategies to enhance performance; however, the emergence of Industry 4.0 technologies has bred focus on the possibility of attaining more levels of operational performance. Despite being demonstrated helpful at enabling supply chain (SC) strategies, the literature linking Industry 4.0 with SCM strategies is still in its infancy. Thus, this work investigates the degree to which “Industry 4.0 technologies” enable the implementation of lean and agile practices and subsequently assesses the potential performance implications of integrating Industry 4.0 technologies with the SC operations.

The work employs an exploratory case study approach using empirical data from selected organisations drawn from an Estonian manufacturing cluster and digital solution providing companies. The data collected via interviews were used to assign numerical scores and subsequently aggregated across the five cases for the research variables of interest. The work is crowned with a model grounded on the cross-case analysis to depict which technologies impact each of the lean and agile practices.

The analysis enabled comprehension of the potential impact and level of importance of the main Industry 4.0 technologies on lean and agile practices and ultimately the potential implication on performance. The findings revealed that the technologies have a high impact on the practices. Although the impacts are of varying degrees, the analysis provides means to identify the technologies with the most significant impact on lean and agile SCM and the sets of practices with the greatest likelihood of being enabled by various digital technologies.

The work presents various lean and agile practices that practitioners can deploy to operations, alongside the technologies that could support the implementation of the practices towards achieving the various performance measures. Also, it provides some guides for the digital solution providing companies towards understanding the SCM practices that can be improved upon by various digital technologies. This enables them to have more saleable proposals for intending companies who might be sceptical about transiting into the digital operation phase.

This is the first attempt to empirically address the connection between Industry 4.0 technologies and the integrated lean and agile strategies despite literature backing of the complementary nature of the two SCM strategies.
