the current work was carried out to characterize welding of aisi 310 austenitic stainless steel to inconel 657 nickel-chromium superalloy. the welds were produced using four types of filler materials; the nickel-based corresponding to inconel 82, inconel a, inconel 617 and austenitic stainless steels 310. of the two joints involved, this paper describes the choice of welding consumables for the...

objective: the present study was designed to investigate the analgesic effect of oral and i.p. administration of alcoholic viscum album (v.a) fruit extract as a rich source of alkaloid substances. materials and methods: experimented animals were divided into control and treatment groups. the treatment rats received different doses of the v.a fruit extract, which was prepared from alcoholic sma...

In the present study, 1.1 volume percent of nano size copper was incorporated into pure tin using hybrid microwave sintering assisted powder metallurgy route. Microwave sintered samples were extruded both at room temperature and at 230 °C. Microstructural characterization studies were conducted on the extruded samples to investigate the distribution characteristics of secondary phase and grain ...

background and objective: hyperalgesia is one of the marked clinical signs of patients with diabetes mellitus that affects their lifestyle. this study was conducted to assess the anti-nociceptive effect of chronic administration of curcumin in streptozotocin (stz)-diabetic rats using formalin, hot tail immersion, and paw pressure tests. materials and methods: this study was conducted on 40 male...

OBJECTIVE Therapeutic ultrasound is an effective deep heating modality commonly applied alone or after cooling or heating of the treatment area. The purpose of this study was to examine the tissue temperature rise in the human triceps surae muscle group after ultrasound with prior heating via a silicate gel hot pack. DESIGN AND SETTING This study was designed as a 2 x 2 x 3 factorial with rep...

introduction: hyperalgesia is considered as one of the marked signs of subchronic diabetes mellitus in patients that could affect their lifestyle. this study was designed to investigate the anti-nociceptive effect of chronic administration of quercetin in streptozotocin (stz)-diabetic rats using formalin and hot tail immersion tests. methods: rats were divided into control, control or diabetic ...

This paper presents investigative results of the energy efficiency of hot water production for sanitary uses by means of gas-fired water heaters with the combustion chamber sealed with respect to the room in single-family houses and multi-story buildings. Additionally, calculations were made of the influence of pre-heating the air for combustion in the chimney and air supply system on the energ...

This paper modeled heating air of a room through examining free convection in a 3D chamber. The chamber had cold and hot sources with Tc and Th temperatures, respectively. Its other walls were adiabatic. This study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. To conduct the st...

A Monte Carlo shielding model for PET/CT clinics Robert L. Metzger and Kenneth A. Van Riper Radiation Safety Engineering, Inc Chandler, AZ Abstract Modern PET/CT clinics consist of a scanner room housing the double gantry PET/CT unit and a control area, two or more quiet rooms where patients rest prior to scanning, and a hot lab where doses are prepared. Of these areas, the scanner room, quiet ...

For over the past several decades, there has been a great concern about energy crisis and lackof non-renewable resources. Residential buildings take more than 25% of the total energy consumption and morethan 75% of energy consumption in these buildings is for heating, cooling and hot sanitary water. On the other hand,traditional buildings of Iran were designed according to ecological conditions...
