The purpose of this study was to survey the current techniques and methods of analysis in bronchoprovocational challenges currently in use. A questionnaire was sent to 94 investigators who had recently published an article in which a bronchoprovocational technique was used. They were asked to answer questions regarding the techniques used in challenge procedures and to calculate the results of ...

A mobile system comprising of a Geiger-Muller (GM) dosimeter connected with a smart phone was used for ambient gamma dose rate survey within the districts and on the roads within the state of Kuwait. While the dosimeter provides data on gamma dose rates, the smart phone provides the GPS navigation information and saves the data for subsequent analysis and mapping. The survey covered a total dis...

X-ray machines that comply with the ISO requirements for calibrating personal dosimeters sometimes are not available in a world region, mainly in developing countries. This is used as an excuse for a lack of personal dosimeter calibration and, consequently, a lack of reliability in the individual monitoring programs. Considering the availability of x-ray machines in many hospitals, this work sh...

introduction: the aim of the present study was to investigate the effects of srp assisted by the two clinical treatment methods of diode laser or chlorhexidine gel applications in comparison with srp alone. methods: eight patients with moderate to severe chronic periodontitis, each with at least three pockets 4–7 mm deep, were selected for this study. over 66 pockets were selected and randomly ...

introduction: the aim of this study was to compare the antibacterial efficacy of diode laser 810nm and photodynamic therapy (pdt) in reducing bacterial microflora in endodontic retreatment of teeth with periradicular lesion. methods: in this in vivo clinical trial, 20 patients who needed endodontic retreatment were selected. after conventional chemo mechanical preparation of root canals, microb...

introduction: to improve laser hair removal (lhr) for dark skin, the fluence rate reaching the hair follicle in lhr is important. this paper presents the results of a comparative study examining the function of wavelength on dark skin types using 755 nm alexandrite and 810 nm diode lasers. methods: the structure of the skin was created using a realistic skin model by the advanced systems analys...

Multicentre studies of airway responsiveness (AR) are increasingly important tools in asthma epidemiology. Because comparisons of AR are made between centres it is essential that measurement techniques are accurate and standard. This study investigated the Mefar dosimeter which is currently used in the 35 centre European Community Respiratory Health Survey (ECRHS) with the next phase currently ...

The European Directive 96/29/EURATOM and adapted national regulations on radiation protection are claiming new limits of radiation exposure and the introduction of new measuring quantities. Dosimeters for area monitoring of penetrating X-ray and gamma radiation have to measure the ICRU operational quantity ambient dose equivalent, H*(10). In this paper, the development stages of a passive H*(10...

Due to its excellent remote measurability and high spatial resolution, the fiber optic-based radiation dosimeter has been extensively explored for its usability in medical applications by several researchers [1-2]. In the previous work [3,4], we reported the result of our investigation on feasibility of a photon dosimeter constructed with a BGO(Bi4Ge3O12) or GSO(Gd2SiO5) scintillator piece coup...
