The Stability

“Osseointegration” as formulated by Alberktson is crucial for implant survival and success. Osseointegration is a measure of implant stability. Measuring implant stability helps to arrive at decisions as to loading of an implant, allows choice of protocol on a patient to patient basis and provides better case documentation. A successful implant reflects good bone to implant contact and is determined by implant stability both primary and secondary. Implant stability is achieved at two different stages – primary (immediately after implant placement) and secondary (3-4 months after implant placement). Implant stability has been confirmed to affect the process of osseointegration and therefore is essential to understand the methods to measure implant stability and factors influencing. Various methods are developed to assess implant stability which suggests the prognosis of an implant.

AbstractCarbon black-filled polymer composites were investigated as sensing materials for organic liquids. Polypropylene and polystyrene which were selected as matrices and various amounts of carbon black were considered as the main factors influencing sensitivity of the composites in view of the percolation theory. Disposable filaments were produced of these materials. Change in their electrical resistivity was measured upon immersion in benzene, toluene, xylene, ethylbenzene and their mixtures. It has been found that studied materials were sensitive to the composition of liquid mixtures of organic solvent. Relationships between the filament response and volumetric fraction of the components were presented. The studied materials have shown promising sensing properties, which suggest their applicability for identification and quantification of multicomponent organic liquids.

The COVID-19 pandemic has had an unprecedented impact on the labor market. The psychological pressure and uncertainty caused by the current changing workplace environment have led to negative consequences for workers. Considering the predictive relationship between employee engagement and wellbeing and in light of this unprecedented situation that affects workers of all the industries worldwide, this study aims to identify the key main drivers of employee engagement that can lead to employee wellbeing in the current context. Through a literature review, a theoretical model to strengthen engagement in times of COVID-19 is proposed. The main factors are conciliation, cultivation, confidence, compensation, and communication. Whereas prior to the pandemic, firms had already understood the need to achieve this, it is now considered a vital tool for staff health and wellbeing. This article makes two main contributions. First, it provides a model for boosting employee engagement, and therefore, wellbeing. Second, managerial suggestions are made to apply the theoretical model.

The thermal environment is one of the main factors that influence thermal comfort and, consequently, the productivity of occupants inside buildings. Throughout the years, research has described the connection between thermal comfort and productivity. Mathematical models have been established in the attempt to predict changes in productivity according to thermal variations in the environment. Some of these models have failed for a number of reasons, including the understanding of the effect that several environment variables have had on performance. From this context, a systematic literature review was carried out with the aim of verifying the connection between thermal comfort and productivity and the combinations of different thermal and personal factors that can have an effect on productivity. A hundred and twenty-eight articles were found which show a connection between productivity and some thermal comfort variables. By means of specific inclusion and exclusion criteria, 60 articles were selected for a final analysis. The main conclusions found in this study were: (i) the vast majority of research uses subjective measures and/or a combination of methods to evaluate productivity; (ii) performance/productivity can be attained within an ampler temperature range; (iii) few studies present ways of calculating productivity.

Systematic Collection

Social mobility is one of the concepts which is the most intrinsically bound to sociology. Hence, the diachronic analysis of this concept contributes to our understanding of sociology and the way that the discipline has changed, as it turned to individual social trajectories according to different topics. Aimed at contributing to this understanding, I’ve developed a literature review based on a systematic collection of the scientific publications in social sciences directly addressing social mobility. A database with conceptual and methodological variables was compiled (N=1054) and worked on. Distinct periods in the life course of this concept have been identified, with the emergence of a scattered concept (1920–1959), the golden age of social mobility (1960–1989), followed by a period of fragmentation and resistance (1990–2012). These three periods are characterized by different methodological and geographical hegemonies, flows and volumes of publications, and also by different tendencies and theoretical and disciplinary rivalries.
