In this paper, we focus on the limb-brightened, prolate spheroidal cavity of the radio galaxy Cygnus A, as revealed by the Chandra X-ray Observatory. We use the shock heated, thermal intracluster medium around the expanding cavity to infer the properties of the radio synchrotron-emitting gas inside the cavity. The gas along the N and S edges of the cavity is found to have an average temperature...

In 160 fetuses the width of transparent septum, lateral ventricles and IV ventricle prenatally during ultrasound examination were studied. Pregnant women divided into two groups, main group consisted pregnant in a state hypothyroidism, control included with uncomplicated pregnancy. The analysis our data showed that hypothyroid there is an expansion cavity anteroposterior size compared group.

Lendon (1902) pointed out that, although it had been generally assumed that the cavity in the lung left after removal of a hydatid cyst soon becomes obliterated,'this was not by any means invariable. He described two cases in which a pulmonary cavity was found at necropsy some time after complete expulsion of the hydatid membranes by coughing. Dew (1928) stated that in some cases in which the c...

schwannoma is a benign encapsulated slow-growing tumor that originates from schwann cells of the peripheral nerve sheath. it usually occurs in the head and neck; however, it is rare in the oral cavity. the tongue is the most common site of intraoral schwannomas, followed by the floor of the mouth, palate, gingiva, vestibular mucosa, lips and mental nerve area. we report a rare case of schwannom...

spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. spindle cell neoplasms can affect the oral cavity. in the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. this article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.  ...

This study was designed to clarify the three dimensional features of naso-maxillary complex in cleft lip and palate (CLP) by using computed tomography (CT) and to examine its change following an upper dental arch expansion. Sequential CT images with 2mm-thickness were obtained for 11 unilateral CLP boys (UCLP), 6 bilateral CLP boys (BCLP) and 4 boys without cleft (non-cleft). Additionally, two ...

The work is devoted to theoretical and experimental investigations of dynamics high-speed underwater supercavitating vehicles with cone cavitators. cavitators are considered as operating controls the vehicle motion. mathematical model a “slender” unsteady cavity based on G.V.Logvinovich principle independence section expansion used. Experimental studies rotary were carried out at tank Institute...

Settlements on the ground surface often relate to excavating an underground cavity in cities. Movement can create a void between wall of cylindrical and lining. Thus, this study proposes approximate solution under undrained conditions, based relationship empirical analytical methods for predicting settlement around cavity. Based mathematical formulas, results obtained by geometrical representat...

aim: the aim of this study was to compare cusp deflection, infraction and fracture in teeth filled with three temporary filling materials. materials & method: forty five extracted human premolar teeth were chosen. after root canal therapy and mesio-occluso-distal cavity preparation, samples were randomly divided into three groups , each contained 15 teeth and filled with three temporary filling...

In the last 10 years we have operated on 33 cases of hydatid cyst of the liver with intrathoracic rupture. Twenty-one out of 33 cases ruptured into bronchi, in seven the rupture affected the pleural cavity, and in six simultaneous rupture into the bronchus and pleural cavity occurred. Laboratory tests were not carried out in all cases. The Casoni intradermal test was carried out in 23 cases and...
