background: today, moving toward high quality and efficient education is essential in educational systems. to achieve it, management, research and educational programs should evolve consistent with the produced knowledge, professional developments and standards. regarding the important role of midwifery education in improvement of social health, the current study was carried out to identify the...

With the rapid development of the economy, the sulfur dioxide (SO2) emission from China since 2000 is of increasing concern. In this work, we first presented the change of SO2 emission in China since 2000 using a technology-based methodology. Then, we compared the SO2 emission data with a variety of official statistics, ground-based measurements and satellite observations of sulfur related quan...

background: in recent year, the accreditation process as the most important assurance and improvement of the quality of higher education, especially in medical sciences, has been set forthed. the need for accreditation of nursing faculties as the same of medical sciences has been acutely felt. yet there are not compiled standards at the same time, to describe present and desirable quality via a...

To gain a greater understanding of the spatial spillover effect of greenhouse gas emissions and their influencing factors, this paper provides a spatial analysis of four gas pollutants (CO2 emissions, SO2 emissions, NOx emissions, and dust emissions). Focusing on China, the paper also explores whether the four gas pollutants are influenced by the emissions of neighboring regions and other possi...

To examine the effects of China’s national policies of energy conservation and emission control during 2005– 2010, inter-annual emission trends of gaseous pollutants, primary aerosols, and CO2 are estimated with a bottom-up framework. The control measures led to improved energy efficiency and/or increased penetration of emission control devices at power plants and other important industrial sou...

the united states and russia are two important actors in international system. the geography of their national interests is global and extra-regional; therefore, the quality of their relationship affects the security of international system. it can create security or can cause insecurity in international system. after the disintegration of soviet :union: there has been more interaction between ...

Sulfuric acid (H2SO4), formed from oxidation of sulfur dioxide (SO2) emitted during fossil fuel combustion, is a major precursor of new airborne particles, which have well-documented detrimental effects on health, air quality, and climate. Another precursor is methanesulfonic acid (MSA), produced simultaneously with SO2 during the atmospheric oxidation of organosulfur compounds (OSCs), such as ...
