Gas injection is widely used in secondary refining processes to homogenize chemical composition and temperature and to remove inclusions. It is an industrial requirement to minimize the size and concentration of inclusions in the product while minimizing production time to save energy and lessen refractory wear. Gas bubbling is effective to increase the cleanliness of steel mainly by two mechan...

BACKGROUND Discharge against medical advice (DAMA) is a global clinical phenomenon contributing significantly to adverse patients' outcome. Literatures abound on self-discharges in specific medical subpopulations. However, multidisciplinary studies on this subject in our region are few. AIM To prospectively evaluate cases of DAMA in a wholesale multidisciplinary perspective at Federal Staff M...

Doubly polished thin sections, originally prepared for fluid inclusion studies, present great advantages in the study of microfossils in volcanic rocks. Better visibility and light conditions, variation in thickness of the thin sections and the possibility to combine fluid inclusion studies with microfossil studies lead to a wide range of advantages over ordinary thin sections. This includes th...

The inclusion complexes of rifampicin with sucralose and beta-cyclodextrins were prepared by spray drying method. The complexes were characterized by size analyses, scanning electron microscopy, differential scanning calorimetry and x-ray diffraction methods. The results indicated the amorphous nature of resultant products. The solubility, in vitro release and skin permeation of the drug were e...

OBJECTIVE To review the incidence of cerebrospinal fluid leak after vestibular schwannoma removal reported in the literature. DATA SOURCES MEDLINE and PubMed literature search using the terms "acoustic neuroma" or "vestibular schwannoma," and "cerebrospinal fluid leak" or "cerebrospinal fluid fistula" covering the period from 1985 to the present in the English language literature. A review of...

Transabdominal ultrasound not always allows to determine the nature of ascites based solely on its characteristics. AIM The aim of the study was to present difficulties in determining the nature of ascites using transabdominal ultrasonography solely based on extra-organ lesions as well as, after the inclusion of the overall abdominal assessment and the clinical picture. MATERIALS AND METHOD...
