Necessity of Conducting Environmental Sedimentology Studies in Ancient Sites

The effect of environmental factors on the location of ancient sites around the ancient northern lakes of the desert plain (Holocene)

Introduction Site selection of human habitats in pre-historic times, unlike the current periods, has been strongly influenced by natural factors. Studies may be focused on three areas including paleoclimate, paleogeomorphology and archeology in order to identify environmental factors affecting primary habitats. Based on studies, most of the ancient lakes in central Iran were formed during the Q...

Animal Rights Consideration is a Necessity in Conducting an Experiment

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Thiamin triphosphatase and conducting sites.

I. Is the monomolecular model as proposed by the electrophysiologists still adequate? Thus Hodgkin and Huxley [1, 2] were able to show that the sodium conductance of the membrane (gNa) rapidly raised and then falls down within msecs to the resting value, while de potassium conductance (gK) increases to a steady value stable as long as E m is kept constant. Hodgkin and Huxley have proposed empir...

Access and Necessity for Road Emergency Sites

Background: Fatal road accidents are among the most important causes of mortality in the world; Iran has one of the world’s highest accident fatality rates. Therefore, it is important to have efficient pre-hospital emergency services. Objectives: The main aim of this study was to assess the road emergency sites (RECs) in Iran. Materials and Methods: Provincial data were used for this purpose. C...
