High prevalence of the metabolic syndrome among Northern Jordanians

Abstract: Background The prevalence of the metabolic syndrome is rapidly increasing with a considerable ethnic variation within and across populations. This study was conducted to estimate the prevalence of the metabolic syndrome and its individual components using Adult Treatment Panel III (ATP III) criteria among Northern Jordanians. Methods Data were analyzed from a cross-sectional study that included a random sample of 1121 northern Jordanians aged 25 years and above. The metabolic syndrome was defined by ATP III criteria. Results The age-adjusted prevalence of the metabolic syndrome was 36.3% (95% CI 33.6–39.0%) (28.7% among men and 40.9% among women). The prevalence increased significantly with age in men and women. The prevalence of the metabolic syndrome was significantly higher in women than in men in age groups of 40–49 and 60 years and above. Low HDL cholesterol was the most common abnormality in men (62.7%), and abdominal obesity was the most common abnormality in women (69.1%). Conclusions Prevalence of the metabolic syndrome in North Jordan is considerably higher than in developed countries and other Arab populations. An integrated approach is needed for the prevention and treatment of the metabolic syndrome.

Forage Yield and Nutrient Uptake as Influenced by Secondary Treated Wastewater

Abstract: The effect of irrigation of forage crops with treated wastewater on the yield and nutrient uptake was evaluated under field conditions. Three field experiments were conducted at a farmer's field near Ramtha Wastewater Treatment Plant, Jordan. Corn (Zea mays) was planted for two seasons as a summer crop while vetch (Vicia sativa) was planted for one season as a winter crop during 1994–1995. Plots were irrigated with either potable water (PW) or wastewater (WW) in amounts according to the following treatments: (i) PW equivalent to 100% class A pan reading (PW); (ii) WW equivalent to 100% class A pan reading (WW1); (iii) WW equivalent to 125% class A pan reading (WW2), and (iv) PW with application fertilizer equivalent to nitrogen (N) and phosphorus (P) content of WW1 (PWF). Treatments were replicated four times in randomized complete block design. Plant samples were taken during the growing seasons and were analyzed for dry weight, yield, yield components, and nutrient uptake. The results indicate ...

Developing Free-Convection Gas Flow in a Vertical Open-Ended Microchannel Filled with Porous Media

Abstract: The developing hydrodynamic and thermal behaviors of free convection gas flow in a vertical open-ended parallel-plate microchannel filled with porous media are investigated numerically. The extended Darcy-Brinkman-Forchheimer model is used to model the flow in porous medium and the solid and fluid media are not assumed in local thermal equilibrium. The microflow regime considered is the slip flow regime. The slip in velocity and jump in temperature are found to decrease in the axial direction of the flow. The friction factor is found to decrease as Knudsen number, Forchheimer number and Grashof number are increased. However, the friction factor is found to increase as Darcy number increased. On the other hand, Nusselt number is found to decrease as Knudsen number, Darcy number and thermal conductivity ratio are increased, whereas it increased as Forchheimer number, Grashof number and Biot number are increased.
