Extensive use of pressurized steam in the oil and gas sectors has led to incidents where workers were seriously injured. In this study a test device and procedure to measure heat transfer through fabrics during steam exposure were developed and evaluated. Several factors were considered while designing the test device to simulate work site conditions. Fabrics were exposed to steam at 2 distance...

[1] Linked tectonic, geochemical, and biologic processes lead to natural arsenic contamination of groundwater in Holocene alluvial aquifers, which are the main threat to human health around the world. These groundwaters are commonly found a long distance from their ultimate source of arsenic, where chemical weathering of As-bearing minerals occurs. We propose a ‘‘GBH-As’’ model that ties togeth...

tectonic processes are major factors controlling landform development in tectonically active areas. in order to evaluate quantitative measurement of tectonic activities in the alamarvdasht basin in the south of iran, six different morphological indices including stream-gradient index (sl), drainage basin asymmetry (af), hypsometric integral (hi), valley floor width-valley height ratio (vf), dra...

The concept of water footprint (WF) is an important breakthrough in the evolving of methodologies, approaches and indicators for measuring freshwater appropriation and assessing the wastewater discharge. Industrial water footprint (IWF) methodology, which concentrates on the industrial production stages, can present a clear graphic of freshwater consumption and impacts caused by wastewater disc...

Thrombolitic fabrics of the Rocknest Formation, Northwest Territories, Canada (Hoffman, 1975; Grotzinger and Hoffman, 1983; Grotzinger, 1986a, 1989b) were disputed by Kennard and James (1986) and Kennard (1989) and classified as cryptomicrobial boundstones. Under close re-examination, these rocks reveal mesoscopic and microscopic fabrics which are indeed thrombolitic when considered in the cont...

Results of dyeing of cotton fabrics with a bifunctional reactive dye were significantly improved when the fabric after bleaching with hydrogen peroxide was treated with catalase for the elimination of hydrogen peroxide residues from the fabrics. Compared to processes with a varying number of washing steps, with and without commercial reducing agents, the consumption of water could be significan...

Traumatic false aneurysm of the thoracic aorta is not uncommon. But accordingly this case is unusual in its ten year delay between injury and presentation and treatment. A victim of the Iran-Iraq war is presented with a false aneurysm of the thoracic aorta ten years after a bullet injury to the chest and thoracic spine. Penetrating chest wounds, mechanisms of injury and diagnosis are also ...

A variety of tectonic processes spread along the circum-Mediterranean orogenic belts driven by convergence major plates, episodes slab retreat and lateral vertical mantle flows. Here, we provide an updated view crustal stress strain-rate fields for Albanides belt in eastern Adria-Eurasia boundary. We framed a new geodetic-based source model 2019 Mw6.4 Durrёs earthquake light regional deformatio...

Earth's largest calderas form as the ground collapses during immense volcanic eruptions, when hundreds to thousands of cubic kilometres of magma are explosively withdrawn from the Earth's crust over a period of days to weeks. Continuing long after such great eruptions, the resulting calderas often exhibit pronounced unrest, with frequent earthquakes, alternating uplift and subsidence of the gro...
