Photosynthetic rates of six pistachio cultivars were studied including Ohadi, Kalleh-Ghochi, Akbari, AhmadAghaii, Rezaii Zoudras and Haratii. Measurements were done using OFF and ON shoots at different stages of fruit growth and development included: - Beginning of endocarp growth; - pith hardening; - Beginning of endosperm rapid growth; - end of embryo development; - ripening and harvesting ti...

OBJECTIVE Orthodontic diagnosis and treatment planning for growing children must involve growth prediction, especially in the treatment of skeletal problems. Studies have shown that a strong association exists between skeletal maturity and dental calcification stages. The present study was therefore taken up to provide a simple and practical method for assessing skeletal maturity using a dental...

Digital acquisition and analysis of sleep data has become more common over the past 20 years. Many investigators have developed strategies to record and analyze sleep in a quantitative way. Initially, digital recording and analysis were restricted by technical limitations. With current technology, the technical limitations of computer acquisition, data storage, and analysis are less constrainin...

It would be nice if we could talk about sleep and memory as if there were only one type of memory and one type of sleep. But this is far from the case. Sleep and memory each comes in many forms, and furthermore, memories can go through multiple forms of post-encoding processing that must be individually addressed. Finally, sleep stages per se do not affect memories. Rather, the neuromodulatory ...

investigation into total phenolics and their spectrum in the buds and corms of saffron crocus and a study of polyphenol oxidase changes in the apical bud during different stages of growth and development showed that changes in the growth and development of the apical bud may be related to changes in the composition of phenolics in the corm. a sudden intense change in content and kind of phenoli...

Chronic pruritus is a debilitating condition with numerous etiologies. Many patients suffer from nocturnal pruritus, which can decrease quality of life and affect mortality in hemodialysis patients. Nocturnal pruritus may occur in all sleep stages but is most prevalent in stages N1 and N2. Further research is needed to elucidate the pathophysiology of nocturnal itch, which will aid in the devel...

A system for computer-assisted encoding, tabulation and analysis of visually scored sleep data is presented. The main features of the system are: (1) The use of computer-readable optical scan sheets for direct encoding of the sleep data. This eliminates the need for a separate transcription and/or key-punching operation. (2) The development of a visually scored data base, organized by NREM and ...

in order to investigate the absorption and translocation of glyphosate and 2,4-d during various stages of growth in swallow-worts weed populations, this study was carried out in 2010 at the iranian agricultural, medical and industerial research institute of atomic energy organization. treatments used in this study included three different stages of growth, four weed ecotypes of swallow-worts, a...

in dry region, root systems play a major roll in controlling plant growth and yield due to their importance in absorbtion of water and nutrients. in order to evaluate the morphological characteristics of root chickpea and obtaining proper morphological makers for screening drought resistant genotypes, four experiments were conducted in different phenological stages of growth including, seedling...
