(Continued on p. 2) Large European Data Base Indicates STM Effective Method of Family Planning Since 1984, German researchers from the University of Dusseldorf and the University of Heidelberg have been developing and analyzing a data set of menstrual cycles collected from multiple European sites. This long-term menstrual cycle data base (of 32,788 prospectively collected menstrual cycles) was ...

Özet Yazılım testinde uygulanabilecek en basit yaklaşım verilen bir kod parçasındaki bütün olasılıkları test etmektir. Bu durum zaman ve bütçe kısıtları nedeniyle pratikte imkansızdır. Yazılım hata tahmini yöntemleri proje yöneticileri tarafından, test aşamasında, kısıtlı olan kaynakları efektif bir şekilde dağıtmak için kullanılmaktadır. Bu alandaki çalışmalar özellikle 2005 yılından itibaren ...

BACKGROUND Buruli ulcer (BU) is a necrotizing bacterial infection of skin, subcutaneous tissue and bone caused by Mycobacterium ulcerans. Although the functional impairment caused by BU results in severe suffering and in socio-economic problems, the disease remains largely neglected in Africa. The province of Bas-Congo in Democratic Republic of Congo contains one of the most important BU foci o...

The steady sta te photolysis of 5-bromouracil (BU) in aqueous solution has been studied as a function of wavelength, pH , tem perature, and hydrogen-donor concentration. U nder all conditions studied, the prim ary reaction is shown to be C-Br bond cleavage followed by abstraction from the hydrogen-donor to give uracil and H B r. A t pH > 12 further products are formed. In deoxygenated aqueous s...

Reactions of the dianion [Te((t)BuN)P(μ-N(t)Bu)2P(N(t)Bu)Te](2-) with I2 or [Cp*RhCl2]2 unexpectedly produced complexes of the novel spirocyclic Te5 dianion [{(t)BuN(Te)P(μ-N(t)Bu)2P(Te)N(t)Bu}2μ-Te](2-), which is N,N'-coordinated to two Na(+) ions in the disodium derivative and adopts a Te,Te',Te''-bonding mode in the Cp*Rh complex.

This paper entails an in-depth study of the system bu er size requirements for parallel scienti c applications that communicate regularly with four or six neighbors. The goal of this study is to address two major issues: (1) for future system designs, which system features signi cantly impact the system bu er size requirements and (2) for systems where users can set the system bu er size (e.g.,...

We identified risk factors for Buruli ulcer (BU) in Benin in an unmatched case-control study at the Centre Sanitaire et Nutritionnel Gbemoten in southern Benin. A total of 2,399 persons admitted from 1997 through 2003 and 1,444 unmatched patients with other conditions in 2002 were recruited. Adjusted odds ratios were determined for age, sex, place of residence, Mycobacterium bovis BCG vaccinati...

They give re...

To investigate how top-down (TD) and bottom-up (BU) information is weighted in the guidance of human search behavior, we manipulated the proportions of BU and TD components in a saliency-based model. The model is biologically plausible and implements an artificial retina and a neuronal population code. The BU component is based on feature-contrast. The TD component is defined by a feature-templ...
