UNLABELLED Environmental conditions such as lighting and thermal comfort are influencing factors on sleep quality and visual tiredness. The purpose of this study was the determination of the relationship between thermal comfort and light intensity with the sleep quality and eye fatigue in shift nurses. METHOD This cross-sectional research was conducted on 82 shift-work personnel of 18 nursing...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...
Underground railway systems, can generate heat from their operations to raise the temperatures of carriages and the station substantially. This may lead to passenger discomfort and complain especially in warm weather conditions that prevail in Tehran if underground environment is not cooled. Transportation air conditioning Committee of American Society of Heating, Refrigerating and air-conditio...
The present paper presents a thermodynamic approach to assess the quality of human-thermal environment interaction and quantify thermal comfort. The approach involves development of entropy generation term by applying second law of thermodynamics to the combined human-environment system. The entropy generation term combines both human thermal physiological responses and thermal environmental va...

Background & Aims: Multiple evidences available about zinc oxide nanoparticles (nano-ZnO) ameliorative effects on neuroinflammation that worked in contrast to mechanisms activate with paclitaxel. In this study, effect of local and intraperitoneal application of nano-ZnO on paclitaxel-induced acute and chronic thermal hyperalgesia in mice was evaluated. Materials & Methods: Adult male mic...
Double Skin Façades (DSF) is one potential response to two major problems, i.e., low Indoor Environmental Quality (IEQ) and high energy consumption. The second skin provides thermal comfort, optimal sound performance, and better day lighting and ventilation. Many typologies of DSFs are widely used mostly in countries of cold climates. In Iran, however, they are less known, and therefore,...
sustainable and energy efficient design issues are key to the way good buildings are designed in the 21st century. no building designer today should be without the basic skills offered by the unique multidisciplinary studies of architectural design, based on energy use in buildings. however, this paper is focusing of effect of air movement on human comfort, as a key element of building design. ...
Nowadays, the issue of thermal comfort has been raised as one of the important factors in the quality of urban spaces along with physical factors. In fact, the quality of urban spaces is important for the use of citizens and should be considered. However, due to the impact of various parameters in urban open spaces that affect the thermal comfort of users and the lack of codified principles in ...
