The floating zone (FZ) method is one of the growth techniques used to grow single crystal materials. FZ growth is achieved in a containerless environment (without a crucible) by the movement of a molten zone of a solid rod, which forms a free-standing liquid bridge between two solid sections. However, the surface tension along the free surface of the molten zone varies due to temperature and co...

Statistical properties of the temperature field in turbulent convection are studied experimentally. We show that the skewness of the plus and minus temperature increments can be used to quantitatively characterize the mixing zone in the convective flow and the result reveals how the mixing zone evolves with the Rayleigh number. We also present evidence for the saturation of the temperature stru...

[1] The Uganik Thrust is a fossil out-of-sequence thrust fault which was active over a period of 3 Ma during the early Tertiary until activity ceased with the subduction of the Kula-Farallon spreading ridge at 57 Ma. During this period the fault experienced at least 1 km of throw and developed a strongly asymmetric damage zone. The brittle damage zone in the footwall of the fault acted as a con...
Dynamical models are essential for model-based control methodologies which allow smart buildings to operate autonomously in an energy and cost efficient manner. However, buildings have complex thermal dynamics which are affected externally by the environment and internally by thermal loads such as equipment and occupancy.Moreover, the physical parameters of buildingsmay change over time as the ...
Aims & Backgrounds: The present study was conducted to determine and evaluate thermal comfort in Shahrood. The main goal is to identify the best times for outdoor tourism in this city based on climatic conditions. Methodology: This is a descriptive-analytical research. Two quantitative indices Olgyay and Effective Temperature (ET) And Bahmanpour et al., (2012) model were used to determine the s...
The preferential synthesis of heat shock proteins (Hsps) in response to thermal stress [the heat shock response (HSR)] has been shown to vary in species that occupy different thermal environments. A survey of case studies of aquatic (mostly marine) organisms occupying stable thermal environments at all latitudes, from polar to tropical, shows that they do not in general respond to heat stress w...
Many biodiversity hotspots are located in montane regions, especially in the tropics. A possible explanation for this pattern is that the narrow thermal tolerances of tropical species and greater climatic stratification of tropical mountains create more opportunities for climate-associated parapatric or allopatric speciation in the tropics relative to the temperate zone. However, it is unclear ...
The Quchan fault is located in Quchan - Shirvan area which is a part of Chenaran- Bojnourd plain in Kopeh-Dagh zone, NE Iran. The Quchan active fault with northwest – southeast trending is one of the most important strike-slip faults in the area which its activity led to the numerous historical and instrumental earthquakes. The Neo-tectonic activities of this fault are investigated by the drain...
