In this study, we used the can technique, containing CR-39, to estimate the radon concentration from the soils in Karbala city, Karbala governorate, Iraq, radon concentrations and effective dose rate in soil have been measured by using a long-term technique for alpha particle emission with solid state nuclear track detector type CR-39. It has been selected fifty-five different locations for soi...

Introduction: In pediatric patients, titratable infusions often do not follow the standard concentrations used for adults. Dosing is usually weight based and for neonates fluid volumes are often restricted to prevent fluid overload. Thus, pediatric infusion bags are typically custom concentrations tailored to the needs of an individual patient. The physician normally specifies the dose, e.g.., ...

Methods All pregnant FMF patients treated at the FMF clinic of the Sheba Medical Center from May 2010 onwards, consenting to participate in this observational study, were studied prospectively for the occurrence of attacks. Attacks were recorded by patients in diaries provided on enrollment and relied by phone to a study coordinator on a monthly telephone call or on a pre-specified physician vi...

Inhalation of indoor radon has been recognized as one of the health hazards. In the present work a set of indoor radon measurements was carried out, in different Egyptian houses in Alexandria city, built of the same type of building materials, using time–integrated passive radon dosimeters containing LR-115 Type II solid state nuclear track detector. Measurements were carried out from October 2...

In this paper, we consider identifying the minimum effective dose (MED) in a dose–response study when survival data are subject to random right-censorship, where the MED is defined to be the smallest dose level under study that has survival advantage over the zero-dose control. To this end, we suggest single-step-down testing procedures based on three different types of weighted logrank statist...

For many years antipneumococcal serum was administered in relatively small doses at intervals of 8 hours and injections were continued until the fever subsided (1). Such a slow method of giving antiserum necessitated a prolonged period of treatment and patients often succumbed to the pneumonia before they had been given adequate quantities of antibody. The importance of administering large dose...

The best conditions for synthesis of starch hydroxypropyl sulphate as per the dry method were firstly established. This was done through a thorough investigation into factors affecting the synthesis including concentrations of both the NaOH catalyst and the 2-hydroxy-3-chloropropyl sulphate along with duration and temperature of the reaction. The resultant newly synthesized 2-hydroxy-3-chloropr...

This study was conducted to evaluate the anthelmintic effectiveness of Albizia anthelmintica, as a first step in investigating the hypothesis that livestock self-medicate. In July 2006, an observational study was conducted with 56 young female lambs, to validate A. anthelmintica efficacy. Faecal egg per gram for Coccidia, Strongyle-type, Monezia, Strongyloides and Dicrocoelia eggs were counted ...

Radiotherapy planning is a complex problem which requires both expertise and experience of an oncologist. A Case Based Reasoning (CBR) system is developed to generate dose plans for prostate cancer patients. The proposed approach captures the expertise and experience of oncologists in treating previous patients and recommends a dose in phase I and phase II of the treatment of a new patient cons...
