Identification and Estimation of Causal Effects of Multiple Treatments Under the Conditional Independence Assumption The assumption that the assignment to treatments is ignorable conditional on attributes plays an important role in the applied statistic and econometric evaluation literature. Another term for it is conditional independence assumption. This paper discusses identification when the...

development of new cultivars with high seed yield and desirable characteristics are major goals of lentil program for moderate and semi warm climate of iran. kimiya is a new lentil (lens cultivars medik) cultivar with high-yield, yield satability and adaptability to rainfed conditions. the iranian agricultural research, education and extension organization issued registration for kimiya on 9 au...

water deficit stress is the most important environmental constraint for growth, yield and productivity of crops, including the oil seed crops. this study was aimed at studying the influence of differing irrigation régimes on growth, chlorophyll , proline and some antioxidants content along with grain yield, yield components and oil content of sesame genotypes using a 4-replicate split plot rand...

A novel optical biosensor based on simultaneous multiwave length detection surface plasmon resonance (SPR) has been developed for immunosensing. The sensor is designed on the basis of fixing angle of incidence and measuring the reflected intensities of light in the wavelength range of 400–800 nm. The SPR spectra are shown in terms of reflected light intensity verus wavelength of incident light....

white bean (phaseolus vulgaris l.) is an important legume food crop in iran and many other countries. it is grown on 110248 hectares in iran, mostly in fars, lorestan, markazi, zanjan and chahar mahal-va-bakhtiari provinces. due to its high value in human nutrition and exportation, considering that most grown cultivars of iran are the runner type beans, with low marketability values and suscept...

Research into the mode of action of the essential oil of Melaleuca alternifolia (Tea tree oil) is briefly reviewed. Its mode of action is interpreted in terms of the membrane-toxicity of its monoterpenoid components and different approaches for determining cell membrane damage are discussed.

The primary tumors of the pleura are usually examined under two headings: diffuse and localized tumors. In the localized form, there is no relationship with asbestosis (1). Localized fibrous tumors were previously known by names such as benign mesothelioma, submesothelial fibroma and localized fibrous mesothelioma. Today, they are usually referred as localized fibrous tumors (2). These tumors c...
