The effects of initial load and load history on the ultimate strength of strengthened RC beams were examined by externally bonded CFRP sheets. The main experimental parameters included different levels of sustaining load at the time of strengthening, and load history. Experimental results show that sustaining load levels at the time of strengthening have important influences on the ultimate strength of strengthened RC beams. If the initial load is the same, the ultimate strength of RC beams strengthened with CFRP sheets is almost the same regardless of load history at the time of strengthening.展开更多

Firstly, a key achievement demonstrates that attempts to create a conducive climate for change should recognize that the unit of change in any organization is, ultimately, the individual. Levers for such initiatives should navigate the macro-organizational change narrative and translate change generalities into specific individual actions and behaviors. Secondly, learning from an implementation gap, similar efforts would gain better traction in engagement and empowerment by leveraging on an influential cross-functional team made up of enthusiastic supporters of the required change, to foster ownership and to embrace change across the organization. Key characteristics that should be represented on the team include leadership skills, expertise, credibility, effective communication, and a sense of urgency. Thirdly, in terms of sustaining change, twin lessons surge to the fore. On a positive note, by progressing its values-set into an annual staff award, there is a pointer to the potential of innovatively encouraging and rewarding employees to live the value qualities. And, on the flip side, a need is underscore of the critical role of seamless executive leadership, providing ongoing co-creating windows for instilling positive attitudes and creating synergies among related strategic initiatives.展开更多

Most of the literature availableas on date are predominantly based on western studies, where theindividual’s personal achievement, autonomy, control, power are consideredto be most important. But these western models often influenced by theirindividualistic philosophy and cultural values are quite inapplicable forpluralistic Indian society, where we believe in collaboration and teamwork.Rare attempts have been made to develop an indigenous model to measurethese attributes in our society. The present study is first of its kind to assessthe salient and non-salient needs of technical students pursuing their studiesin India. Authors have identified measures of the students’ engagement invarious academic, co-curricular activities and their performance outcomes.A sample of Four-hundred and Sixty-five (N=465) engineering/sciencestudents were collected through purposive sampling exclusively from IITKharagpur , a premier technical institute in eastern India where studentsacross the country got selected and joined on merit basis, through thenational level joint entrance examination for Engineering and Science, thetoughest examination in the country, known as IIT-JEE.

Systematic resource investigation can elevate fractional conversion of this area' s mineral drugs resources superiority. Research on natural mineral drugs of this area can upgrade the translation rate of resource superiority and accelerate the development of local medical industry, especially, it can provide scientific data for founding the strategic design of Chinese traditional medicine's trademark of Jilin Changbai Mountain. Since the resource of mineral drugs can not be regenerated, it must be exploited scientifically, utilized reasonably and protected effectively its sustaining application.展开更多

Investigation of measures that working population would need and use with their work-life in an attempt to stay healthy and fit, could potentially reveal significant association that could extend workability and enhance work productivity such as performance, presenteeism, job satisfaction. Evaluation with selective longitudinal health profiling;employment prerequisites;socio-economic and psychological scales could characterize health measures significantly associated with work sustainability. Such health measures could potentially be employed by US working population early in their life and occupation to sustain and improve workability in their later epoch.展开更多
