Endobronchial actinomycosis was found to be the cause of right-sided atelectasis and haemoptysis in a 57 year old man without predisposing conditions. Fibreoptic bronchoscopy revealed occlusion of the intermediate bronchus by yellow-white masses. The diagnosis was confirmed histologically and by positive Actinomyces culture from bioptic material. Prolonged antibiotic treatment resulted in compl...

Abstract The recently proposed “dynamically driven double-degenerate double-detonation” (D 6 ) scenario posits that Type Ia supernovae (SNe) may occur during dynamically unstable mass transfer between two white dwarfs (WDs) in a binary. This predicts the donor WD then survive explosion and be released as hypervelocity runaway, opening up exciting possibility of identifying remnant stars from D ...

From a minimum of total energy of celestial bodies, their basic parameters are obtained. The steady-state values of mass, radius, and temperature of stars and white dwarfs, as well as masses of pulsars are calculated. The luminosity and giromagnetic ratio of celestial bodies are estimated. All the obtained values are in a satisfactory agreement with observation data.

Having knowledge of stability of an underground space depends on stresses and strains around it. Creating underground tunnels leads to significant changes in the rock mass stress. Therefore, to achieve the necessary stability, stresses and deformations around the tunnel must be examined carefully. Usually, stress-strain behavior analysis is conducted in two-dimensional mode. This paper was cond...

The purpose of this paper is to report the results of a study of the mucin, or mucin-like metachromatic substance, sometimes found in the white matter of the brain. This substance, occurring in small masses, has been referred to as " mucocytes." During the course of work on " grass sickness " in horses, these masses have been found; it therefore has become urgent, before continuing this investi...

The merger of compact binaries, especially black holes and neutron stars, is frequently invoked to explain gamma-ray bursts (GRB’s). In this paper, we present three dimensional hydrodynamical simulations of the relatively neglected mergers of white dwarfs and black holes. During the merger, the white dwarf is tidally disrupted and sheared into an accretion disk. Nuclear reactions are followed a...

Hair casts are small white yellowish keratinous structures that totally wrap the hair shaft. They are characterized by asymptomatic, semifirm, tannish, freely movable, cylindrical masses, distributed along the scalp hair. This condition has been found in three women, whose case histories are described.

abstract background: evaluation of breast masses in women under 40 years old starts with a triple test score (tts) which is composed of clinical breast examination, mammography and fine needle aspiration. increased breast density in this age group decreases the sensitivity of mammography. so deciding whether to biopsy such nondiagnostic lesions or not is subject to challenge. breast masses up t...

In dense stellar systems the frequent dynamical interactions between stars play a crucial role in the formation and evolution of compact binaries. We study these processes using a novel approach combining a state-of-the-art binary population synthesis code with a simple treatment of dynamical interactions in dense star cluster cores. Here we focus on the dynamical and evolutionary processes lea...
