Loading shaft of the mixing device is complex. Because the operating regime is characterized by a random variation of the regime parameters, it is difficult to determine an exact theoretical approach, from the point of view of calculation of the shaft. The stress shaft of a mixing device takes into account only partally of the real state of loading. At present, there is no unitary methodology for calculating of shaft for mixing devices. Although the effect of the mixer weight on the own frequency, has been partially taken into account when the shaft-mixer system rotates in the air, it must be reconsidered if the shaft-mixer system rotates in a liquid. The calculation presented in this paper will take into account "hydrodynamic mass" mam of liquid, corresponding to the mixer that actually vibrates with it. This contributes to an increase of its inertia, and to reducing of the own frequency (respectively of the critical speed). In this paper, the influence of the working environment on the deflection of vertical cantilever shaft will be considered, and calculation relations for own pulsation of the shaft equipped with a mixer will be set, with consideration of mixer hydrodynamic mass. For this purpose, it is calculated hydrodynamic mass mh attached to the mixer, and the reduction factor of pulsation due to hydrodynamic mass.

Background: The objective of this article is to analyse if there are significant relationships between the most valuable companies operating in Spain regarding professional performance, according to nationality and location within their Autonomous Communities or any superior aggrupation. To do that, a sample of 100 companies has been selected. Methods: The methodology followed is based on the selection of the 100 highestvalued companies from the point of view of Human Resources’ policy for the period 2013-2016 and through the measurement of six factors: Talent Management, Retribution, Work environment, CSR, Training and Employees’ perception, and classified by nationality and location. The study was based on 12 hypotheses, using the Unifactorial Variance’s Analysis, Pearson correlations and regressions. One limitation could be the fact that this study refers to a particular period, focusing on Spain and the variables mentioned, based on questionnaires. The added value of this work lies on the newness as it has a quantitative character, and on the fact that most of the hypotheses do not comply. Results and Conclusion: This allows to deny certain beliefs that affirm that European and American companies operating in Spain are more attractive than the Spanish or the Mediterranean ones.

In this study, an analysis of independent studies dealing with occupational safety training in different learning environments, in which various learning materials are used, was carried out. As a method, meta-analysis method was used. For this purpose, databases were used to collect national and international articles and papers suitable for the purpose of the study. Studies that did not mention the tools, equipment and environment used in education in the collected studies were excluded from the research, and 18 studies were included in the meta-analysis. The data obtained studies are categorized according to the education models, the sectors in which the education is applied and the characteristics of the participants in the education. As it is known, occupational health and safety procedures aim at a healthy and reliable working environment for its employees. However, the ultimate goal is to raise not only employees but also future generations with this awareness. The most important instrument of this is undoubtedly education. For this reason, it is necessary to develop training models suitable for the work environment, age, gender and every conceivable situation.

This article is a practitioner reflection on taking a meta mediation perspective on working with two organizations in co-creating a positive and constructive working environment. This perspective is grounded in the theoretical framework of strategic conflict management systems. The approach taken is to consider a specific process for engaging with organizations by looking at the two case study organizations – one small and growing, the other medium-sized and resource-constrained. The reflection first considers the antecedents for both organizations in engaging in this way. It then sets out the process for whole organization engagement through dialogue. The outcomes for each organization are then shared. The conclusion reached is that both organizations benefited from the engagement in terms of improvements in work environment, working relationships, conflict competence and organizational performance. Some of the ethical considerations for mediators working with organizations in this way are reflected on including neutrality and impartiality, confidentiality and self determination.
