effects of different k/ca ratios on the growth, yield and physiological characteristics in galia (cucumis melo var. reticulatus l. naud. cv. galia) grown in hydroponics were evaluated. the experiment was arranged in a completely randomized design of three replicates. melon seeds were sown in a medium containing perlite and vermiculite (3:1 v:v) and then irrigated with water containing different...
Objective: Assessment and management of pain in patients under artificial respiration and hospitalized in Intensive Care Units (ICUs) are difficult, and is less considered by physicians and nurses. This study aims to determine the effect of classical music on physiological characteristics, and observational and behavioral measures of pain in unconscious patients admitted to ICUs. Methods: This...
in order to examine the ecological conditions and characteristics of fraxinus excelsior l. in the northern forests of iran 6 main areas as well as some miscellaneous ones , have been selected in the region respectively in : lomir2, shafaroud , park - e-noor , ahlam , alandan and noor.
the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...
The excess female infant mortality observed in South Asia has typically been attributed to gender discrimination in the intra-household allocation of food and medical care. However, studies on child nutrition find no evidence of gender differences. A natural explanation could be that in environments of high infant mortality of females, the surviving children are healthier, so that child nutriti...
In dioecious plants, females typically invest more biomass in reproduction than males and consequently experience stronger life-history trade-offs. Sexual dimorphism in life history runs counter to this pattern in Silene latifolia: females acquire less carbon and invest more biomass in reproduction, but males pay a higher cost of reproduction. The species is sexually dimorphic for many traits, ...
talent identification is a process through which those with the highest chance to succeed in the future will be determined. the purpose of the present study was to investigate the application of a multivariate approach in talent identification of adolescent soccer players. the research population consisted of all soccer players in tehran province aged between 12 and 16 years old. a battery of t...
Sexual selection is a powerful evolutionary mechanism that has shaped the physiology, behaviour and morphology of the sexes to the extent that it can reduce viability while promoting traits that enhance reproductive success. Predation is one of the underlying mechanisms accounting for viability costs of sexual displays. Therefore, we should expect that individuals of the two sexes adjust their ...
