  The aim of the present study was to investigate the population dynamics of Liza klunzingeri, in Hormouzgan province waters located in northern coasts of the Persian Gulf and Oman Sea. This study was carried out from October 2007 to September 2008. samples were collected from commercial stake traps. The relationship between weight and fork length was found to be W= 0.0214 F.L2.8233 suggesting ...

Carbon sequestration in golf course soils has received some attention, but energy use and greenhouse gas (GHG) emissions from turfgrass maintenance are poorly quantified. This study developed a model to estimate consumption GHG turf applied the 14 courses located northern USA over 3-yr period. Energy that result operations were divided into three scopes. Scope 1 consisted of onsite (n = 14), 2 ...

CONTEXT Raloxifene is a promising breast cancer prevention agent in postmenopausal women at increased risk for breast cancer. The effects of raloxifene in premenopausal women are unknown. OBJECTIVE We evaluated the effect of raloxifene in premenopausal women at increased risk for breast cancer on bone mineral density (BMD). DESIGN This was a phase II clinical trial. SETTING This study was...

The heterogeneous ecosystems in the Mediterranean Basin (MB) are becoming sensitive to water stress. To investigate climatic stress, a budget study was conducted over basin using TerraClimate simulations for long temporal range (1990–2020). According accounting, forested regions received highest precipitation (P) on average compared other land use types (annual mean ≈633 mm yr−1), and even then...

Radiofrequency catheter ablation (RFCA) has recently become a management option for pediatric tachycardia. We reviewed the records of a total of 100 patients (aged 10 months to 19 yr) who had undergone RFCA, from March 2000 to June 2004. Types of arrhythmia (age, acute success rate) were as follows: atrioventricular reentrant tachycardia (AVRT, 9.0+/-3.7 yr, 66/67), atrioventricular nodal reent...

Systems containing two white dwarfs can descend in less than a Hubble time from wide or close binary stars with initial masses of components exceeding 0:8 M. The degenerate components may be composed of helium, of mixtures of carbon and oxygen, or of mixtures of oxygen and neon (with traces of sodium and magnesium). They may be detached or semidetached. We present a numerical model of this popu...
