Abstract We present a statistical study of the largest bibliographic compilation stellar and orbital parameters W UMa stars derived by light-curve synthesis with Roche models. The includes nearly 700 individually investigated objects from over 450 distinct publications. Almost 70% this sample is comprised observed in past decade that have not been considered previous studies. estimate ages cata...

(Abridged) We present an analysis of the 700 ks Chandra ACIS-S observation field around Spiderweb Galaxy at z=2.156, focusing on nuclear activity in associated large-scale environment. identify unresolved X-ray sources down to flux limits 1.3X10^{-16} and 3.9X10^{-16} erg/s/cm^2 soft hard band, respectively. search for counterparts optical, NIR submm bands belonging protocluster. detect 107 wit...

Following dark adaptation, the response to irradiance of chlorophyll (Chl) fluorescence, the light-induced absorbance change around 820 nm (to measure reaction center Chl of photosystem I [PSI] P-700 oxidation), and CO2 fixation were examined in pea (Pisum sativum L.) leaves under a range of conditions. Initially, P-700 oxidation is restricted by a lack of regeneration of PSI electron acceptors...

in the present health care environment, cost-benefit analysis is extremely important. in this screening program, the minimal cost of screening dipstick urinalysis in 1601 asymptomatic school children was determined. the process of screening was similar to all the studies. the minimal cost utilizing 3 general physicians was calculated. costs were determined by using current charge for supplies o...

environmental effects associated with pesticide application have motivated the development of integrated pest management programs throughout the world. advantages of the implementation of such a program like food security, biodiversity, consumer and producer security can be stated as economic value. estimating the economic value of such programs can be helpful in identifying the benefits as wel...
