the considerable role of ziziphus spina christi in preserving water and soil and its resistance to heat and drought, the necessity of planting this species for afforestation and restoration of their habitats and urban green space is obvious. the aim of this study was to determine the best irrigation and seedbed treatments before planting for ziziphus spina christi seedling production. this stud...
We investigate the in vivo patterns of stem cell divisions in the human hematopoietic system throughout life. In particular, we analyze the shape of telomere length distributions underlying stem cell behavior within individuals. Our mathematical model shows that these distributions contain a fingerprint of the progressive telomere loss and the fraction of symmetric cell proliferations. Our pred...
In a greenhouse research, the effects of soil water conditions, sewage sludge and chemical fertilizers on growth characteristics and water use efficiency of rice (Oryza sativa L. cv. Ali Kazemi) were studied in a loamy sand alkaline non-calcareous soil. The study was performed as a factorial experiment in a randomized complete blocks design including soil water conditions in three levels (conti...
In order to evaluate of distinctness, uniformity and stability (DUS) of morphological traits, three new genotypes of cotton (GT40, TBL60 and SKT134) were tested using a complete randomized blocks design with 4 replications. In general, 39 quantitative and qualitative morphological characteristics were measured. Results showed quantitative morphological characteristics including number of stem n...
Mint is an important medicinal herb that is cultivated in different parts of the world. In order to investigate the effects of salinity stress on morphological characteristics of spearmint (Mentha spicata L.), an experiment was conducted in 2013, based on complete randomized design, under hydroponic conditions, at Research Greenhouse of Faculty of Agriculture, Ferdowsi University of Mashhad, Ir...
Variation in angiosperm vessel diameter is of major functional significance. In the light of recent models predicting optimal vessel taper given resistance imposed by conductive path length, we tested the prediction that plant size should predict vessel diameter, with dryland plants having narrower vessels for their stem sizes. We assembled a comparative dataset including vessel and stem diamet...
peppermint (mentha piperita l.) is one of the most important plants producing essential oil. an experiment was carried out using a randomized complete block design with 3 replications to study the effect of salinity stress on growth parameters, essential oil percent of peppermint. 4 levels of salinity solution containing 0, 50, 100 and 200 mmol nacl was applied in irrigation plantings in a gree...
There are still some controversial issues regarding total hip arthroplasty including cemented vs. cementless, short stem vs. long stem. A literature review on the currently published survival results of short stems is encouraging and appears to be comparable with that of traditional uncemented stems. However, only few mid-term and long-term follow-up studies are available; studies with more pat...
Peppermint (Mentha piperita L.) is one of the most important plants producing essential oil. An experiment was carried out using a randomized complete block design with 3 replications to study the effect of salinity stress on growth parameters, essential oil percent of peppermint. 4 levels of salinity solution containing 0, 50, 100 and 200 mmol NaCl was applied in irrigation plantings ...
