Loss of pre-load with time, commonly known as ‘Relaxation’ is an established phenomena. Behaviour of a bolted joint depends upon the pre-load in the bolts in use, not the pre-load introduced by the mechanic. Loss of pre-load is expected due to the many factors such as embedment relaxation, gasket creep, elastic interactions, and vibration loosening or stress relaxation. In a gasketed joint, due to the gasket flexibility, relaxation is always substantial during preliminary passes, as 80 to 100% loss is not uncommon in almost all the bolts, resulting in a dynamic behaviour. Pre-load in a gasketed joint is stabilized and retained to certain extent in the final passes only. In a non-gasketed joint, due to no gasket and no rotation its static behaviour is concluded. This paper highlights the factors affecting the amount of relaxation with time and presents important considerations that can reduce this. Both the short and long term relaxations are recorded and a ‘best fit’ model for relaxation behaviour is derived.

Although the motivational technique of goal setting has consistently and reliably improved performance in industrial psychology research, this beneficial effect has not been clearly demonstrated in the sport domain. The many proposed explanations for this discrepancy have resulted in a controversy in the literature. However, scientists have overlooked the importance of statistical power. A meta-analytic review of the literature investigating the effects of goal setting on performance in sport and exercise could help to clarify the state of knowledge. The meta-analytic procedures described by Hedges and Olkin (1985) were used to statistically combine 36 studies identified as meeting inclusion criteria. Results indicate that, overall, setting goals improves sport by 0.34 of a standard deviation. Moderate, absolute, and combined short- and long-term goals were associated with the greatest effects. Additional moderator variables were identified, and the extent to which they alter the goal setting–performance relationship is discussed.

Probing Gandhi’s Political Strategy in View of His Civilisational Politics in India

The Impact

The present article seeks to critically probe Gandhi’s civilisational view of Indian society and politics both from his few articulate and many hidden statements at different stages of his life. His civilisational view is, therefore, analysed from a variety of perspectives: its origin, direction, advocated methods and long-time impact on Gandhian thought, philosophy and activities. It is presumed that such an analysis of Gandhi’s political philosophy with special reference to his civilisational view may clarify some of the mysteries associated with his much cited and often criticised ‘strategies’ of political activity. The article has three parts. The first dwells on the background of Gandhi’s civilisational critique and touches on some of its contents from the political standpoints. The second probes into the many meanings of civilisational politics both from Gandhi’s articulate and hidden statements on the subject. The third reviews the impact of Gandhi’s civilisational politics on the course and strategy of his political action, and its legacy for the future. The underlying idea is that satyagraha in the Gandhian philosophical context is most intelligible when viewed from the short- and long-term perspectives of civilisational politics.

Beaver Dams

<p>Beavers profoundly alter streams by building dams. Beaver dams change how water, sediment, nutrients and energy flow through stream corridors enhancing both habitat diversity and landscape connectivity. Humans are captivated by learning from nature and trying to mimic it, especially in human-degraded environments. There is considerable eagerness for using beaver dam analogues (BDAs), also called simulated beaver structures, as low-tech, low cost solutions for restoring the functioning of degraded streams where beavers are not present and cannot survive. The use of BDAs in stream enhancement projects, especially in the western United States, is outpacing the research, leading to questions about whether BDAs do, in fact, yield similar ecosystem-scale effects as natural beaver dams. We review the different names used for BDAs, discuss the many ways these structures can be built and how different types function, and how they compare to real beaver dams. We conclude the talk by exploring what we can expect from various types of BDAs in the short and long term and whether these structures can lead to stream and riparian zone restoration that can facilitate the return of beavers. </p>

Basic factors affecting the appearance of algae discoloration on the surface of the system are recognized effects of the external environment (external temperature and humidity, short- and long-term radiation, precipitation, wind and air pollution). Internal factors are often neglected by international technical documents on the evaluation of the effectiveness of resistance to biocorrosion of the External Thermal Insulation Composite System (ETICS). Based on literature data and in situ research, the basic internal factors responsible for the occurrence or intensification of the biocorrosion process were systematized. Internal factors were divided into two groups: (1) plaster properties and (2) solutions for material layouts and building details. The results of research on these factors indicate that they directly or indirectly influence the humidity condition of plaster and biocorrosion development is a consequence of this state. The opposite issue, the influence of biocorrosion on plaster properties, is analyzed only in patrial way.
