GSM call re-establishment service allows a mobile station to resume a call in which the radio link has been temporarily interrupted due to interference or bad signal (which is referred to as an interrupted call). This service increases end user satisfaction and network quality perception. In this paper, we propose analytic models to study the performance for call re-establishment service. Our s...

paraschistura ilamensis , new species, is described from the tigris river drainage, iran. it is distinguished from other species of paraschistura in iran by a combination of the following characters: emarginate caudal fin, stout, deep and scaled body, deep caudal peduncle, 7-10 irregular and interrupted vertical pale brown bars on flanks, two obvious dark spots on the upper and lower caudal fin...

h s o Background. Patients with both interrupted aortic arch IAA) and truncus arteriosus (TA) have worse outcomes han those with either lesion in isolation. We determined utcomes and associated factors in this rare group. Methods. From 1987 to 1997, 50 (11%) of 472 neonates ith IAA were identified with TA. Site of aortic arch nterruption was distal to the left subclavian artery in 6% and betwee...

background and aim: speech understanding almost never occurs in silence. verbal communication often occurs in environments where multiple speakers are talking. in such environments, babbling noise masks speech comprehension. consonants, in comparison to vowels, are more sensitive to noise masking. consonants provide most acoustic information needed for comprehending the meaning of the word. sin...

Glioblastoma multiforme (GBM) tumors are the most common type of brain tumors and resistance to radiotherapy. This study aimed to investigate the differential effect and mechanism of tumor microenvironments, cycling hypoxia and non-interrupted hypoxia, on tumor cell radiosensitivity in the human U87 glioblastoma tumor model. We exposed U87 cells and mice bearing U87 glioma to experimentally imp...

In the measurements of reverberation time, measurement methods different accuracy are used depending on room. For ordinary rooms, made using interrupted noise method, which consists determining decay curve after switching off excitation source The for arrangements and receiver arrangements, at least three repetitions each such points. Due to a realization measurements, several dozen curves obta...

PURPOSE To compare running and interrupted suturing techniques for porcine vesicourethral anastomosis with regard to procedure time, histopathologic effects, and leakage. MATERIALS AND METHODS Twelve domestic pigs were randomized to a running (N = 6) or an interrupted (N = 6) vesicourethral anastomosis with polyglycolic acid sutures. In each case, the bladder was drained for 7 days. A cystogr...

Based on the genomic sequences for most archaeal species, only one tRNA gene (isodecoder) is predicted for each triplet codon. This observation promotes analysis of a whole set of tRNA molecules and actual splicing patterns of interrupted tRNA in one organism. The entire genomic sequences of two Creanarchaeota, Aeropyrum pernix and Sulfolobus tokodaii, were determined approximately 15 years ago...

background: noise pollution can contribute to adverse health effects in humans. noise annoyance and related problems, caused by noise emission during the progress of building construction, have become increasingly important. these problems can influence the exposed workers, as well as vicinity residents. the goal of the present study was to assess the noise annoyance due to noise from construct...
