background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...

EL PARE Com que vivia a Batignolles i treballava al ministeri d’Instrucció Pública, cada dia agafava l’òmnibus per anar fins al despatx. I cada matí feia el trajecte fins al centre de París, davant una noia de qui es va enamorar. Ella anava a la seva botiga, cada dia, a la mateixa hora. Era una moreneta menuda, d’aquestes brunes que tenen els ulls tan negres que semblen taques i un color de car...

0. Introduction A number of mathematical techniques have been applied for solving nonlinear problems. Energy Balance [1–3], homotopy analysis [4], variational iteration [5], homotopy perturbation [6,7], the max–min approach [8,9], frequency amplitude formulation [10] and perturbation methods [11] are the most prominent approaches that those have been employed for solving a large number of nonli...

The author contends that sex differentials in childhood mortality in Pakistan are a likely outcome of son preference behavior by parents. Consideration is given to the historical improvement in the female disadvantage in mortality, the neglect of female children, gender and class factors, and son preference and high fertility. Data are from the 1981 Pakistan census and other official surveys....

În cadrul acestei lucrări sunt explorate soluţii de aplicare a specificaţiilor IEC 61499 în modelarea şi implementarea controlului de nivel înalt al holonilor. Conceptele IEC 61499 au fost utilizate ca o tehnologie suport pentru încapsularea controlului inteligent al holonilor, modelarea comunicaţiei interholonice şi configurarea dinamică a holonilor. Modelele şi teoriile propuse au fost valida...

Normal (IMR-90) and SV40-transformed (VA-13) human embryo cells were treated with 8-carbamoyl-3-(2-chloroethyl)imidazo[5,1-d] -1,2,3,5-tetrazin-4(3H)-one (M&B 39565), and the effects of the drug on cell viability and cellular DNA integrity were studied. The effects of M&B 39565 were compared with one of its potential decomposition products 5-[3-(2-chloroethyl)triazen-1 -yl]imidazole-4-carboxami...
