Application checkpoint and restart has been a widely studied problem over the last several decades. Despite immense volume of theory and several research project level implementations, there is very little by way of working solutions for the case of parallel distributed applications (such as MPI programs on a cluster). We describe our experiences in(More)
STUDY DESIGN A unique case report. OBJECTIVE To report a case of severe thoracolumbar kyphosis with abdominal compression causing gastric disturbance after treatment of an osteoporotic vertebral compression fracture and its ultimate management by vertebral column resection (VCR). We propose a new terminology "sternum-into-abdomen deformity" to describe(More)
High blood pressure is one among the leading contributors to burden of disease globally. Approximately 54 % of stroke and 47 % of ischemic heart disease events worldwide were attributable to high blood pressure in the year 2001. There is deficiency of data on the long-term outcome of hypertension in children. In spite of this, there is sufficient evidence(More)
INTRODUCTION The premature loss of primary teeth may reduce arch length required for the succeeding tooth and, hence, predisposes crowding, rotation and impaction of the permanent teeth. There are only limited studies carried out about the prevalence of early loss of primary teeth. AIM The present study was performed to evaluate the prevalence of early(More)
AIM The chest radiograph is widely used for the diagnosis and follow-up of patients with pulmonary venous hypertension (PVH) caused by rheumatic heart disease. Observer accuracy and interobserver agreement on the radiographic diagnosis of PVH is rarely assessed. We have studied this accuracy and agreement in 120 consecutive patients. METHODS AND RESULTS(More)
BACKGROUND & OBJECTIVE Mycoplasmas have been implicated in causing minor to severe respiratory infections in man. Mycoplasmas are considered to act as cofactors in patients with AIDS. A preliminary study was conducted to isolate mycoplasmas from sputum specimens of AIDS patients and non-HIV patients with underlying pulmonary symptoms and signs. METHODS A(More)
In conventional network security simply relies on mathematical algorithms and low counter measures to taken to prevent intrusion detection system, although most of this approaches in terms of theoretically challenged to implement. Therefore, a variety of algorithms have been committed to this challenge. Instead of generating large number of rules the(More)
BACKGROUND Combination chemotherapy ABVD (doxorubicin, bleomycin, vinblastine and dacarabazine) cures ∼70% of patients with advanced Hodgkin's lymphoma (aHL, stages IIB, III and IV) while more toxic escalated BEACOPP (EB, combination of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisolone) increases cure rates to(More)
PURPOSE Dental trauma has become an important aspect of dental public health. The primary requisite before actively dealing with such problems is to describe the extent, distribution, and variables associated with the specific condition. The purpose of this study was to assess the prevalence and role of socioeconomic status and anatomic risk factors in(More)
Ten children from each group of nursing caries, rampant caries, 3-5 dmft/DMFT and caries free children were selected and plaque samples from carious lesion, early carious lesion, sound tooth surface as well as salivary sample were collected. The levels of mutans streptococci and lactobacilli were estimated at all the sample sites. The result further(More)
