Our objective was to determine whether the consumption of green tea, coffee, or black tea influences the incidence of dementia and mild cognitive impairment (MCI) in older people. We conducted a population-based prospective study with Japanese residents aged >60 years from Nakajima, Japan (the Nakajima Project). Participants received an evaluation of cognitive function and blood tests. The cons...

Growing public awareness of climate change requires transportation professionals to integrate green concepts into the transportation planning, design, construction, and operation processes. For the past decade, while many studies have been done regarding carbon emission reduction strategies for on-road and off-road operations, very few have dealt with emission reduction issues in highway projec...

a simple, green and efficient method for synthesis of 2,4,5-trisubstituted imidazoles is described via three-component cyclocondensation of benzil or benzoin, aldehyde and ammonium acetate by using the nano sio2-supported ferric hydrogen sulfate (fhs/sio2), as a catalyst, under solvent-free conditions. the nano sio2 support and catalyst were characterized by x-ray diffraction (xrd), transmissio...

This paper reveals the non-technical elements that affect construction project costs, known as soft cost (SCEs). These elusive have received little attention although they are significant in influencing management decisions of a project. There is much interest mitigation for green projects, but focus generally leaning towards hard aspects. Information about SCEs remains obscure. Qualitative app...

the dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. collection of information about the performance of projects at control points costs money. the corrective actions that may need to be taken to bring the project in line with the plan also costs money. on the other hand, penalties are usually...

This case summarizes a failed systems development project at the Green Valley Hospital. The project was part of a large strategic information systems plan aiming to lower costs, improve the quality of patient care and integrate the hospital's operations. To implement the project, the president of the hospital selected a $5.9 million system by Ibax. The users, who felt that the selected system d...

Abstract—Due to the economic downturn and the deterioration of the living environment, the development of residential buildings as high energy consuming building is gradually changing from “extensive” to green building in China. So, the evaluation system of green building is continuously improved, but the current evaluation work has the following problems: (1) There are differences in the cost ...
