1 social state. The recent era has witnessed the emergence of QOL concepts as an essential health component which looks beyond the morbidity and mere survival of the patients. It leads to the accelerated research on measurement of QOL and its applicability in the health care arena. Several researchers utilized QOL concept to assess the impact of the disease on the individual, efficacy of interv...

This study was conducted to compare the methods of seed bedpreparation in rangelands of Khash region in Sistan and Baluchestan province inIran. A split plot design was conducted based on Randomized complete blockdesign with three replications in 1999. Five seed bed preparation methods wereused as main plot as: 1) Seed sown by passing livestock. 2) Seed sown machinery.3) Seeds sown as drilled in...

Rangelands are the main source of forage production whose degradation is being accelerated due to improper utilities. Furthermore, re-vegetation of palatable plants like Vicia variabilis is more limited in overgrazed rangelands. The objective of this study was to improve degraded rangelands in Meleh-Kabud (Kermanshah, Iran) through planting Vicia variabilis. The research was conducted at experi...

investigating the role of drought stress conditions on physiological characteristics of plant may provide means to understand basic drought resistance. differences in leaf emergence rate, leaf relative water content (rwc), membrane stability index (msi), leaf mass area (lma), net photosynthesis (anet), stomatal conductance (gs), transpiration rate (e), intercellular co2 concentration (ci), ...

The emergence and spreading of chirality on the early Earth is considered by studying a set of reactiondiffusion equations based on a polymerization model. It is found that effective mixing of the early oceans is necessary to reach the present homochiral state. The possibility of introducing mass extinctions and modifying the emergence rate of life is discussed.

The influence of long-term ceftriaxone administration on the emergence of Clostridium difficile was studied with 80 patients receiving ceftriaxone for 14 days. In five patients (6.3%) C. difficile was cultured. The appearance of gastrointestinal disturbances during treatment with ceftriaxone was common, but the rate of emergence of C. difficile in immunocompetent patients was not high.
