تناسب به عنوان یک اصل کلیِ حقوقی در نظام های حقوقی مدرن، به دنبال این عقیده که شهروندان باید در برابر دولت مورد حمایت قرار گیرند و مداخلات تنظیمی دولت بایستی متناسب با اهداف مورد نظر باشد، ایجاد شده است. این اصل نخست در نظام حقوقی آلمان پذیرفته شد و پس از آن با گسترش صلاحیت های اداری، به عنوان یکی از مبانی نظارت بر اعمال دولت، توسعه یافته است. اصل تناسب که انعکاس صریحی در معاهدات اتحادیه اروپایی...
foreign policy cooperation and coordination among the european community member states and presenting europe with a single voice, has long been an important challenge within the european community/european union, especially since early 1970s. in the early 1990s, following the collapse of the ussr and the end of the cold war, there was a general speculation in europe that the ec may be able to p...
background: many epidemiological studies reported significant associations between air pollution and respiratory hospital admissions. proximity of industries to the residential areas may have considerable impacts on air quality and subsequently public health. this paper describes the indirect impacts of closing a large steel industry, broken hill proprietary (bhp), in the lower hunter region...

OBJECTIVES Cigarette packets in many countries display emission numbers such as tar. These numbers may be misleading as they do not represent the amount of toxins delivered to human smokers. This study examined how consumers interpret and understand numerical and descriptive emission information. STUDY DESIGN A discrete choice study was conducted among adult smokers (n = 312) and non-smokers ...
Non-regulatory animal health issues, such as Johne's disease, infectious bovine rhinotracheitis (IBR) and mastitis will become increasing important, with ongoing globalisation of markets in animals and animal products. In response, Ireland may need to broaden the scope of its national animal health services. However, there have been concerns about the respective roles and responsibilities (both...
The Baba Ali deposit is located about 39 km to the north west of Hamadan city. The syenitic pluton intruded and metamorphosed the diorite host rock producing the skarn deposit. Geochemical considerations indicate that the concentration values of rare earth elements in the syenite and diorite range from 35.4 to 560 ppm. Rare earth elements variation in syenitic, skarn and diorite rock are simil...
LiYF4:Eu nanophosphors with a single tetragonal phase are synthesized, and various strategies to enhance the Eu(3+) emission from the nanophosphors are investigated. The optimized Eu(3+) concentration is 35 mol%, and the red emission peaks due to the (5)D0 →(7)FJ (J = 1 and 2) transitions of Eu(3+) ions are further enhanced by energy transfer from a sensitizer pair of Ce(3+) and Tb(3+). The tri...
