to evaluate genetic variation and to study of dry matter remobilization towards seed, 64 bread wheat genotypes were examined in two separated experiments using alpha-latic design of 2 replications during 2002–2003. significant differences observed for most traits in normal and drought conditions. there were considerable variations among genotypes for independent parameters of dry matter remobil...

BACKGROUND This study aimed to measure the hospital productivity using data envelopment analysis (DEA) technique and Malmquist indices. METHODS This is a cross sectional study in which the panel data were used in a 4 year period from 2007 to 2010. The research was implemented in 12 teaching and non-teaching hospitals of Ahvaz County. Data envelopment analysis technique and the Malmquist indic...

BACKGROUND Gastro-oesophageal reflux disease (GERD) is a common disorder with consequences for the patient's health-related quality of life (HRQoL). In Germany, few data are available on the impact of GERD on work-related productivity. AIM To study the impact of GERD on work productivity despite proton pump inhibitor (PPI) therapy and the association between productivity and symptom duration,...

A PERENNIAL ISSUE in the study of organizational behavior is the impact on productivity of participation by workers in a firm's decisionmaking. The question has returned to the foreground in the recent debate over policies to increase U.S. productivity growth.' A large literature is aimed at quantifying the impact of worker participation on productivity though the results from this research fal...

BACKGROUND Due to the increasing health care costs, the issue of productivity in hospitals must be taken into great consideration in order to provide, preserve and promote public health services. Thus, increasing the level of productivity must become the main aim of any hospital. Objective of this study is to determine the total factor productivity and its components over the period under the s...

Fertilization experiments in plant communities are often interpreted in the context of a hump-shaped relationship between species richness and productivity. We analyze results of fertilization experiments from seven terrestrial plant communities representing a productivity gradient (arctic and alpine tundra, two old-field habitats, desert, shortand tall-grass prairie) to determine if the respon...

The problem of assessing the impact of firm entry and exit on aggregate productivity growth is addressed. The proposed method overcomes some problems with currently proposed methods. The paper also addresses some of the problems involved in aggregating outputs and inputs when firms enter and exit so that the one output and one input aggregate productivity decompositions can be applied. It turns...

PH (Puissance de Hydrogen) is an essential ingredient of soil that effects on fertility and productivity of dirt. Barddhaman district is a part of Lower Gangetic Plain fully covered by alluvial soil and popularly known as 'rice bowl of West Bengal' owing to its lofty production. This data article provides a block level data on soil PH that is essential for further investigation of the relations...

Morphological productivity is one of the key issues in the study of derivational morphology. This paper makes a survey of the quantitative measurements of morphological productivity so far proposed by different scholars, and tentatively attempts to point out the pros and cons and also feasibility of each measurement, with a view to provide some assistance for the future researcher who is going ...

Ecosystem functioning, characterized by components such as productivity and stability, has been extensively linked with diversity in recent years, mainly in plant ecology. The aim of our study was thus to quantify general relationships between diversity, community structure and ecosystem functions in metazoan parasite communities. We used data on parasite communities from 15 species of marine f...
