The Difference

The problems related to the standardization of the error in the mass measurements when dividing products into groups and picking according to the difference in mass are considered. On the basis of the theory of probabilities and the basic provisions of metrology, a dependence is obtained to determine the error of the mass difference. Recommendations are given for improving the metrological support of indirect measurements of the mass difference, a formula is determined for calculating the normalized values of errors depending on the tolerances for the mass difference, and criteria for choosing measuring instruments for controlling the mass difference of parts at the stage of completing the connecting rod-piston group during the production and repair of engines are considered. The measurement error is estimated when using preassembly selection of parts by weight. Keywords: quality of measurements, mass measurements, mass difference, indirect measurements, choice of measuring instruments, permissible measurement error, complete set of connecting rod and piston group.

Dieser Beitrag zeigt, dass die durch die Abrichtparameter erzeugte Schleifscheibentopographie nicht nur die Oberflächengüte des Werkstücks, sondern auch dessen Eigenspannungszustand in der Werkstückrandzone in weiten Grenzen verändert. Die Untersuchungen zum Abrichten von Korundschleifscheiben mit einer CVD-Diamantformrolle stellen den Zusammenhang zwischen dem Abrichten unterschiedlicher Schleifscheiben zur Bauteilqualität in Form der Oberflächenrautiefe und randzonennahen Eigenspannungen her.   The quality of the workpiece rim is changed by every grinding process. The grinding wheel topography created by the dressing process has not only influence on the workpiece roughness but also on the surface integrity. The pointed research using aluminum oxide abrasive wheels dressed by CVD diamond dressing discs shows a correlation between the dressing parameters, the workpiece roughness and the surface integrity.

Chip seal is most frequently used as preventive maintenance (PM) treatments on asphalt pavement. However, it’s difficult to make the performance test of chip seal in laboratory. In this paper, the specimen molding method of chip seal is established in laboratory. Firstly, considering the structure and technique condition of the original pavement, a cushion layer of asphalt concrete (AC) is used as under layer of the specimen. Secondly, the construction process of chip seal is simulated in laboratory, which includes spraying emulsified asphalt and/or glass fiber, spreading aggregate, initial rolling and conservation, post-stage rolling and conservation in interval for some time. Lastly, visual inspection and sand patch test are used to evaluate the quality of the specimen. Research results show that the method of specimen molding and test in laboratory could relatively accurately simulate, evaluate and forecast the performance of the chip seal.

Only nonwetted porous membranes can be used in membrane distillation. The possibility of application in this process the capillary polypropylene membranes manufactured by thermally-induced phase separation was studied. The performance of a few types of membranes available commercially was presented. The resistance of the membranes to wetting was tested in the continuous process of water desalination. These studies were carried out for 1000 h without module cleaning. The presence of scaling layer on the membranes surface was confirmed by Scanning Electron Microscope observations. Both the permeate flux and distillate conductivity were almost not varied after the studied period of time, what indicates that the used membranes maintained their nonwettability, and the negative influence of scaling was limited. The role of surface porosity on the pore wetting and influence of membrane wettability on the quality of the distillate obtained were discussed.

The studies revealed that organizational change could create employee’s psychological uncertainty. However, this study argues that the quality of leader-member exchange enables to control the impact of the psychological uncertainty during the change toward employee’s attitude. This study represents job satisfaction and turnover intention as proxy of employee’s attitude for that matter. Based on social exchange theory, quality relationship of leader and employees affects on the relationship of psychological uncertainty and employee’s job satisfaction and turnover intention. This study selected private hospitals experiencing the changes of operational system for complying with national health security system. This study conducted cross-section survey for individual level-analysis. This study produces some findings. Firstly, the LMX has been failed to reduce the negative influence of psychological uncertainty towards employee’s job satisfaction, although the quality of the LMX was good. employee’s job satisfaction is more perceived as  personal afective state experienced during the organizational change. Secondly, the LMX has been successfully moderated the positive influence of the psychological uncertainty towards employee’s turnover intention.The data were collected by using questioners, distributed to the employees who worked in hospitals in Yogyakarta Province. There were 193 questioners that could be collected and analyzed by using Moderated Regression Analysis (MRA) to test the hypothesis by using SPSS application version 21. The result of the study shows that psychological uncertainty had negative correlation to employee’s job satisfaction and positive influence to psychological uncertainty toward turnover intention. Besides, LMX was proven to moderate positive influence of psychological uncertainty toward turnover intention, but it could not moderate negative influence of psychological uncertainty toward job satisfaction.

Grass Pollen Season

Objective: The objective of this study was to compare driving ability, memory, and psychomotor performance during grass pollen season with winter season in untreated patients with SAR. Methods: Patients with SAR were trained and tested during the grass pollen season (summer) and winter. An on-the-road driving test during normal traffic conditions was performed. Primary parameter is the Standard Deviation of Lateral Position (SDLP), i.e. the weaving of the car. In addition, a word learning test and continuous performance test were performed and quality of life was assessed. Patients were included if in winter the Total 5-Symptoms Score (T5SS) was < 3 and in summer the T5SS was > 3. Results: 70 patients were recruited of which 22 started the study. Fifteen patients completed the study of which 11 met the inclusion criteria. These 11 patients had a mean T5SS of 6.8 in summer and 0.6 in winter. Patient reported a significantly reduced overall quality of life during grass pollen season (p<0.0001). No significant effects were found on the driving test, except a significant (but not relevant) decrease in mean speed during the grass pollen season (p<0.035). No significant effects were found on the word learning test and continuous performance test. Conclusion: Our data suggest that moderate SAR symptoms do not impair driving ability, memory functioning and continuous performance. However, given the small sample size future studies should confirm these findings.
