ABSTRACT- Paddy soils make up the largest anthropogenic wetlands on earth. Present study was performed to investigate and compare soil formation of paddy soils with long-term rice cultivation history with non-paddy soils and study the effect of waterlogging on soil pedogenesis. Soil samples were taken from paddy and non-paddy soils derived from the same calcareous parent materials. Some pedogen...

global warming, as a consequence of greenhouse gases accumulation, has exerted significant impacts on biosphere. methane, a product of reduction processes of organic carbon in anaerobic conditions, is mainly emitted from paddy fields. the aim followed in this research is to evaluate the impact of midseason drainage on methane emission from paddy fields. the research was conducted with three tre...

lack of scientific and confirmed researches and expert knowledge about evaluation systems for clinical governance development in iran have made studies on different evaluation systems for clinical governance development a necessity. these studies must provide applied strategies to design criteria of implementing clinical governance for hospital's accreditation. this is a descriptive and compara...

Poverty reduction is a function of economic growth, income distribution and distribution changes. Governance can impact both growth and income distribution. The dominant market-enhancing governance paradigm seeks to enhance the efficiency of markets through ‘good governance’ reforms, ostensibly to trigger or sustain growth. ‘Pro-poor’ good governance reforms purport to enhance the scale and eff...

Existing subsurface scattering rendering algorithms try to reproduce the phenomenon aiming at physically accurate results. Recent research has demonstrated that in some scenarios, to make some assumptions about the way we perceive translucency helps us speeding up calculus achieving real-time results. In this paper we present a new algorithm based on previous perceptual studies general enough t...

background: in spite of the pivotal role of clinical governance in enhancing quality of services provided by hospitals across the country, a scientific framework with specific criteria for evaluating hospitals has not been developed so far. objectives: this study was conducted with the aim to identify the challenges involved in evaluating systems of clinical governance in iran. materials and me...

corporate governance is the system by which corporations are directed and controlled. corporate governance also provides the structure through which company objectives are established, the means to achieve these objectives, and how to monitor their performance. icts have the potential to make organization and its services more transparent by providing easy access to information. this research a...

About 40 years ago, Luther Christman, PhD, RN, FAAN, wrote about an autonomous nursing organization where nurses would be empowered to control their nursing practice. His idea was an early framework for shared governance. As a young doctoral student, I explored shared governance as a concept; I became increasingly frustrated trying to understand what it was. Many organizations adopted what they...
