Introduction: Breast cancer is one of the most common known cancers in women all around the world. It is the most common cause of death in women after lung cancer. Radiotherapy is a method for therapy of cancer in which certain dose of high energy radiations is used to destruct cancer cells. Radiotherapy is designed so that radiation of eartain does to the target area in body i...

Increasing crop biodiversity, such as by adjacent managed crops, is recognized an effective biological control measure. However, few studies have focused on the mechanisms involved in how crops increase natural enemy populations, leading to reduced pest numbers. This study investigated hypothesis that cotton grown sorghum would positively influence feeding and oviposition preferences of ladybug...

We describe allelic series for three loci, mutations in which result in homeotic conversions in two adjacent whorls in the Arabidopsis thaliana flower. Both the structure of the mature flower and its development from the initial primordium are described by scanning electron microscopy. New mutations at the APETALA2 locus, ap2-2, ap2-8 and ap2-9, cause homeotic conversions in the outer two whorl...

This article is devoted to electron beam distortions in the “electron compressor” setup for beam-beam compensation in the Tevatron collider. The distortions are due to interaction of the electron beam with impacting elliptical antiproton beam. We estimate of longitudinal magnetic field necessary to keep the distortions low.

Three-dimensional electron phase-space holes are shown to have positive charges on the plasma background, which produce a radial electric field and force the trapped electron component into an azimuthal drift. In this way electron holes generate magnetic fields in the hole. We solve the cylindrical hole model exactly for the hole charge, electric potential and magnetic field. In electron holes,...
