Intrusions of magma induce thermal aureoles in the country rock. Analytical solutions predict that the thickness of an aureole is proportional to the thickness of the intrusion. However, in the field, thermal aureoles are often significantly thinner or wider than predicted by simple thermal models. Numerical models show that thermal aureoles are wider if the heat transfer in the magma is faster...
To better understand the influence of urban green infrastructure (UGI) on outdoor human thermal comfort, a survey and physical measurements were performed at the campus of the University of Groningen, The Netherlands, in spring and summer 2015. Three hundred eighty-nine respondents were interviewed in five different green spaces. We aimed to analyze people's thermal comfort perception and prefe...
Optimization of process parameters in oriented strand board (OSB) manufacturing is a vital issue for improving product quality. In this study, the Taguchi method (TM) was applied to determine the effects of production factors such as adhesive ratio, press pressure, and pressing time on the thermal conductivity of OSB. Obtained results showed that adhesive ratio is the main factor affecting ther...
spatial distribution of thermal regions is dependent on local factors and circulation patterns in long terms. recognition of spatial distribution of temperature in geographical regions could be help on planning and environmental policies. the aim of this paper is recognition and detachment of thermal regions in iran. for this object, maximum daily temperature data have been provided using 620 s...
in this study multivariate statistical analysis are used to characterize relationships between hydrochemical properties ofthermal and non-thermal springs. four factors for thermal waters and two for non-thermal springs were extracted basedon factor analysis. in thermal springs, the first factor showed high loading on ca, mg, na and k and this factor wasinterpreted as leaching of cations in the ...
A nanofluid is a dilute liquid suspension of particles with at least one critical dimension smaller than ~100 nm. Research works so far suggest that nanofluids offer excellent heat transfer enhancement over conventional base fluids. The enhancement depends on several factors such as particle shape, particle size distribution, volume fraction of nanoparticles, temperature, pH, and thermal conduc...
background and aims: the safe, potent and effective live vaccines against measles, mumps and rubella as important childhood diseases have been available for several decades. several factors can affect the thermal stability of lyophilized vaccine. methods: in this study, the effect of residual moisture on thermal stability of 61 batches of mmr vaccine was investigated using an accelerated method...
Background and purpose: Human-made environments can have negative and positive effects on the planet. One of the two-faceted artifacts is the construction of buildings for people's lives, buildings that are being built irregularly and quickly and lead to excessive consumption of fossil resources and energy waste. become Therefore, one of the most important things in the design of a building is ...
The subject of outdoor thermal comfort has been researched since 1970. Due to its differences with indoor thermal comfort, it must be assessed with the proper indices. Also, the outdoor thermal comfort of each geographical region must be assessed independently. This research aims to study the measurement indices of outdoor thermal comfort and subsequently determine the most relevant index to as...
the major aim of this study was to investigate the relationship between social and cultural capital and efl students’ critical thinking skills. this study takes this relationship in to account to see if people with different sociocultural status are different regarding their critical thinking skills. to this end, 160 university students majoring in english language and literature, english trans...
