the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
this thesis seeks to present a critical reading of virginia woolf’s mrs. dalloway and michael cunningham’s the hours in terms of an intertextual approach, concentrating on dialogic imagination, negativity, transposition and allusion. this study attempts to evaluate cunninghams perception of woolfs life and work by adopting kristevas conception of intertextuality and her consideration of the hou...
A broad spectrum of variably altered igneous rocks with a wide range of grain sizes are compressed and heated over a wide range of pressure-temperature paths in subduction zones. Although experimental kinetic data cannot be extrapolated to predict the rates of blueschist and eclogite formation in nature, textural data from rocks indicate that transformation below temperatures of 150øC is minima...
We present a framework for interpreting the carbon isotopic composition of sedimentary rocks, which in turn requires a fundamental reinterpretation of the carbon cycle and redox budgets over Earth's history. We propose that authigenic carbonate, produced in sediment pore fluids during early diagenesis, has played a major role in the carbon cycle in the past. This sink constitutes a minor compon...
The Shah-Kuh granitoid has intruded in the Triassic–Jurassic, pelitic and psammitic low-grade metamorphic rocks of the NE LutBlock, in Central Iran. Cordierite porphyroblasts are common in the southern pelitic sediments, but are rare in the northern psammiticrocks, in the contact aureole. Deformation fabrics in the contact aureole are well-preserved within the cordierite porphyroblasts. Therela...
Gypsum karst problems in the Permian and Triassic sequences of England have caused difficult conditions for bridge and road construction. In Northern England, the Ripon Bypass crosses Permian strata affected by active gypsum karst and severe subsidence problems. Here, the initial borehole site investigation for the road was supplemented by resistivity tomography studies. The roadway was reinfor...
The study area is part of Karaj Formation in the southern city of Zanjan and is located in the central Iran zone. Rocks of the study area consists of pyroclastic, igneous and sedimentary rocks. Igneous rocks in this aria consist of two categories: acidic (rhyiolite and rhyiodasite) and basic (basaltic andesite). Sahle section in terms of lithology can be equal of the lower shale and middle tuf...
The aim of this study is to determine the stratigraphic position bauxite deposits in Ayrancı region, where most important mineralization Bolkardağı region located. In context, age will be determined by determining erosion surface associated with features during formation and according its side rocks. there are Permian-Cretaceous aged rocks belonging Union, one main tectonic units forming Centra...
Granitoidic bodies of the eastern Misho mountains (SW Marand – East Azerbaidjan) have intruded into Kahar Formation and mafic – ultramafic rocks of Misho mountains and has faulty contact with Triassic carbonate deposits. The composition of these bodies ranges from quartz monzonite to granite and alkali-granite and it is cut by porphyritic granitic and diabasic dykes. The main minerals of these ...
hedging is a multi-purpose rhetorical strategy which is usually used in scientific arguments to secure ratification of claims, reduce the risk of negation, avoid conflict, manage disagreement and leave room for the audience to assess presented information. hedges are frequently used in research articles to mitigate the findings of research endeavors. the present research aims to investigate the...
