In this paper we adopt a geometric perspective to highlight the challenges associated with solving high-dimensional reliability problems. Adopting a geometric point of view we highlight and explain a range of results concerning the performance of several well-known reliability methods. We start by investigating geometric properties of the N -dimensional Gaussian space and the distribution of sa...

The effects of daily repeated doses of monomethylhydrazine (MMH) were studied in monkeys. Groups of monkeys were given from 2.5 to 5 mg/kg IMH i.p. for a total of 23 doses. Other monkeys were given from 7 to 10 mg/kg MMH i.p. for up to 4 days. Baseline and weekly clinical laboratory measurements studied were complete blood count, serum glucose, alkaline phosphatase, and glutamic oxaloacetic tra...

Background and objectives: Hemorrhoids is the most prevalent rectal disease which is defined as enlargement of ano-rectal cushions.  Intensified pressure on vascular plexus of hemorrhoids seems playing a chief role in the development of hemorrhoids. Hemorrhoidectomy is an important surgery to relieve discomforts of patients that suffer from symptomatic hemorrhoids. This review ...

OBJECTIVE The aim of this study was to investigate the effect of Xiaozhi decoction (XZD) on posthemorrhoidectomy pain and analgesic medication consumption. METHODS From May 2013 to March 2015, 315 patients who underwent open hemorrhoidectomy in our hospital were enrolled in this study, of whom, 160 patients were randomly assigned to accept sitz bath with warm water after hemorrhoidectomy (con...

This paper discusses the details of a study undertaken for biomechanical evaluation of a number of Manual Material Handling (MMH) tasks being carried out at a construction site in India. A comprehensive methodology involving a two dimensional dynamic biomechanical evaluation approach is developed for such construction MMH tasks involving carrying and lifting of materials like normal and Reinfor...

OBJECTIVE To evaluate the performance of a system that extracts medication information and administration-related actions from patient short message service (SMS) messages. DESIGN Mobile technologies provide a platform for electronic patient-centered medication management. MyMediHealth (MMH) is a medication management system that includes a medication scheduler, a medication administration re...

PURPOSE Postoperative pain is the main adverse effect of formal hemorrhoidectomy. A new technique based on Doppler-guided ligation of the terminal branches of the superior hemorrhoidal artery was introduced in 1995 as an alternative to hemorrhoidectomy. The authors report a preliminary experience with this procedure. METHODS The Doppler-guided hemorrhoidal artery ligation technique uses a spe...

The aim of this study was to assess the medical treatment in comparison with hemorrhoidectomy in the management of primary grade-4 internal hemorrhoidal disease (IH) and external hemorrhoidal disease (CH). Group I (medical treatment): 127 patients (59 IH, 68 CH) were prospectively collected and medically treated using oral tablet of micronized purified flavonoid fraction (MPFF) containing 450 m...

PURPOSE To determine the safety, pain intensity correlated with age and body mass index (BMI), epidural anesthesia with ropivacaine and clonidine in hemorrhoidectomy. METHODS Eighty patients, both genders, 20-70 years old, ASA I or II, for hemorrhoidectomy were randomly divided into two groups: Control (n=38), epidural anesthesia with 14 mL of ropivacaine 0.75 % plus 0.0266 mL/kg of 0.9% sali...

INTRODUCTION Low pressure valves with ventriculoperitoneal shunts have been proven to lead to good outcomes in the treatment of idiopathic normal pressure hydrocephalus. However, overdrainage complications are often seen with low opening pressures. Efforts have been made to obtain good outcomes without overdrainage complications by decreasing the hydrostatic pressure component using special val...
