This study draws on archaeological, stylistic, and technological evidence to explore ceramic brick production of the medieval Islamic period in southern Karakum region Turkmenistan, home many urban sites along so-called Silk Roads. We focus a 9th–12th centuries a.d. assemblage recovered from site Dandanakan/Daş Rabat during first season ToKa (Town project) 2019. Special emphasis is paid charact...

In this study, the overall performance of air PV/T, based on energy and exergy analysis has been investigated. Two combinations of air PV/T, which consist of unglazed and glazed air PV/T, are considered. Thermal analysis and numerical calculations were carried out, and the performance parameters of the system for the climate conditions of Kerman were studied. The results are presented in graphs...

The environmental concern, ensuring comfort for occupants, pushed us to search for the impact of glazed loggia on thermal comfort of adjacent space in Cons tantine climate, having s trong climatic cons traints. An experimental s tudy is undertaken and described in this paper. Analysis of the in situ results is also discussed. This work shows that in winter glazed loggia benefit largely from sol...

statement of problem: the effect of porcelain surface on the antagonist acrylic teeth has not been widely studied. objectives: this study aimed to investigate the effect of polished porcelain, glazed porcelain, and natural teeth (as the control group) on the acrylic resin teeth. materials and methods: in this experimental-laboratory study, a total of 60 specimens of glazed and polished porcelai...

Stainless steel alloys containing 8% to 12% nickel and 17% to 22% chromium are generally used in orthodontic appliances. A major concern has been the performance of alloys in the environment in which they are intended to function in the oral cavity. Biodegradation and metal release increase the risk of hypersensitivity and cytotoxicity. This case report describes for the first time a CAD/CAM zi...

Medieval architecture of the South Caucasus developed a unique tradition making acroteria shaped as three-dimensional models churches. Since church-shaped have never been thoroughly explored in Georgia, this paper focuses on examples surviving region. Special attention is paid to analyzing architectural and sculptural aspects acroteria, well their function. This aims at discussing both formal f...

This paper focuses on Mathematical Modelling of Single Glazed and Double Solar air heater (SAH) which is special kind heat exchanger that transfers thermal energy from the solar radiation to fluid flowing inside collector. The most potential applications SAH supply hot for heating buildings, maintain a comfortable environment especially in winter season, preheating, desiccant refrigeration, dry...
