The forecasted shortage of fossil fuels and the ever-increasing effect of greenhouse gas (GHG) emissions on global warming and environmental stability are two international problems with major technical, economic and political implications in the 21st century. Therefore, it is urgent to restructure present energy production and utilization systems in order to ensure that fossil fuels are used w...

BACKGROUND Constructing successful online programs requires engaging potential users in development. However, assembling focus groups can be costly and time consuming. OBJECTIVE The aim of this study is to assess whether Tumblr can be used to prioritize activities for an online younger worker risk reduction and health promotion program. METHODS Younger summer parks and recreation employees ...

There is a great deal of interest in constructing Double Skin Facade (DSF) structures which are considered as modern movement in field of Energy Conservation, renewable energies, and Architecture design. This trend provides many conclusive alternatives which are frequently associated with sustainable building. In this paper a building with Double Skin Facade is considered in the semiarid climat...

Designing and constructing a technically complex yet efficient, fully integrated fill-finish facility is no small task. The timeframe can be long, the costs can be high, and the stakes with numerous stakeholders involved, can be even higher. But this case study of one biotherapeutic company’s new fill-finish facility in Hillsboro, Oregon, provides practical insights and steps for success for “j...

Development of cognitive architecture where the agents at different levels exhibit different levels of thinking. The paper primarily focus on building the skill tree at the learning layer of the architecture. These include the discovery of one’s own body, including its structure and dynamics. Also the acquisition of associated cognitive skills such as self and non-self-distinction. This can be ...

Design-based research studies are conducted as iterative implementationanalysis-modification cycles, in which emerging theoretical models and pedagogically plausible activities are reciprocally tuned toward each other as a means of investigating conjectures pertaining to mechanisms underlying content teaching and learning. Yet this approach, even when resulting in empirically effective educatio...

background: successful waste management programs are linked to internal factors, sw (strength and weakness points), and external factors, ot (opportunities and threats), and at the macro level are grounds for sustainable development. studies may be related to david’s study which presented a method to quantify strength, weakness, opportunity, threats (swot) analysis. methods: in this study, desi...
