We review the history of the parallel tempering simulation method. From its origins in data analysis, the parallel tempering method has become a standard workhorse of physiochemical simulations. We discuss the theory behind the method and its various generalizations. We mention a selected set of the many applications that have become possible with the introduction of parallel tempering and we s...
The present study investigates the tribological properties of G350 grey cast iron in various microstructural conditions. Quench and temper heat treatments were conducted at four tempering temperatures, from 400 °C to 700 °C, produce a range tempered martensitic disc samples. Pins slow furnace-cool annealed coarse pearlitic microstructure with some areas ferrite. These samples then used pin-on-d...
Surveillance of Summer Mortality and Preparedness to Reduce the Health Impact of Heat Waves in Italy
Since 2004, the Italian Department for Civil Protection and the Ministry of Health have implemented a national program for the prevention of heat-health effects during summer, which to-date includes 34 major cities and 93% of the residents aged 65 years and over. The Italian program represents an important example of an integrated approach to prevent the impact of heat on health, comprising Hea...

JIS SUP 9A leaf spring steel under hot-forging conditions was subjected to full annealing (FA) and single step-quenching-tempering heat treatments (SQT). Tensile test specimens ASTM E 8 standards have been prepared. The FA process performed by heating all in the furnace at a constant temperature of 800°C for 2 hours, followed cooling furnace. Then, were heat-treated SQT. SQT carried out samples...

This work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used...
Introduction: Heat stress is considered as a serious risk factor to the health and safety of workers in most working environments, especially in outdoor works and jobs that workers are exposed to heat due to the working process. This study aimed to evaluate heat stress among workers of brick-manufacturing units in Qom city based on WBGT index as well as the relationship between WBGT and physiol...
Electrical energy consumption is alarmingly rising, but the availability of conventional sources limited. To meet increasing demand; implementation non-conventional need hour. Solar most sustainable alternative for power generation among families. Resonant inverters are used in low-power high-frequency induction heating appliances. Full-bridge resonant commonly to convert solar received into su...
