OBJECTIVE Green space has been shown to be beneficial for human wellness through multiple pathways. This study aimed to explore the contributions of neighbouring green space to cause-specific mortality. METHODS Data from 3544 Chinese men and women (aged ≥65 years at baseline) in a community-based cohort study were analysed. Outcome measures, identified from the death registry, were death from...
The transition and the Green operators of an interacting N body system are obtained from the solutions of the N-M body problem where M = 1,2,ellipsis,N-2. This is achieved via the development of a cumulative, nonperturbative approach that makes use of existing knowledge on the system when the number of interacting particles is reduced. The method is applied to four interacting Coulomb particles...
At present, green plants exist in all aspects of our lives. And statistics shows that the pest species of green plants is very large. Thus accurate and rapid diagnosis is regarded as an essential component of green plant protection. Moreover, we couldn’t find relevant information easily. That is why pest diagnosis is difficult and inefficient for technicians and farmers. In view of the above, t...
This paper describes in details a commercial green building that has been designed and constructed in Marsa Matrouh, Egypt. The balance between homebuilding and the sustainable environment has been taken into consideration in the design and construction of this building. The building consists of one floor with 3 m height and 2810 m2 area while the envelope area is 1400 m2. The building construc...
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

سیستم های مخابراتی موبایل و ماهواره، به آنتن های کم حجم، کم وزن و با بهره بالا نیاز دارند، هرچند آنتن های انعکاسی سهموی عموما در آن سیستم ها بکار گرفته می شوند و از بهره بالا و تلف پایین برخوردارند ولی حجیم، جاگیر، دارای شکلی انعطاف ناپذیر و سطح بالای تشعشع پلاریزاسیون نامطلوب هستند. یکی از ساختارهایی که به عنوان جایگزین آنتن های سهموی مورد توجه قرار گرفته است. آنتن آرایه انعکاسی مایکرواستریپ، ...
Some twelve years ago, Mark Green [G] made a few conjectures regarding the behaviour of syzygies of a curve C imbedded in IP n by a complete linear system. The so-called generic Green conjecture on canonical curves pertains to this question when the linear system is the canonical one and the curve is generic in the moduli, and predicts what are the numbers of syzygies in that case. Green and La...
Abstract—In the last decades, concerns about the environmental issues lead to professional and academic efforts on green supplier selection problems. In this sake, one of the main issues in evaluating the green supplier selection problems, which could increase the uncertainty, is the preferences of the experts' judgments about the candidate green suppliers. Therefore, preparing an expert system...
