Using Magellan SAR images and the Schaber et al. [1998] crater data base we examined impact craters in the area north of 35øN and determined the geologic units on which they are superposed. The crater density of the regional plains with wrinkle ridges (Pwr) was found to be very close to the global average and thus the mean surface age of the plains is close to the mean surface age of the planet...

Playas are ephemeral, closed-basin wetlands that are hypothesized as an important source of recharge to the High Plains aquifer in central USA. The ephemeral nature of playas, low regional recharge rates, and a strong reliance on groundwater from the High Plains aquifer has prompted many questions regarding the contribution and quality of recharge from playas to the High Plains aquifer. As a re...

[i] An ongoing issue regarding the crustal evolution of Venus is whether or not certain features and processes occurred in the same sequence and at the same time globally. This paper seeks to test one aspect of "directional" models for the geologic history; the inference that all ridge belts are older than regional plains. This test involves traditional geologic analysis, but also involves the ...

Abstract Soil liquefaction is a phenomenon through which saturated soil completely loses its strength and hardness behaves the same as liquid due to severe stress it entails. This can be caused by earthquakes or sudden changes in conditions. Many empirical approaches have been proposed for predicting potential of liquefaction, each includes advantages disadvantages. In this paper, novel predict...

INTRODUCTION Knowledge, attitude, and skills of nurses regarding evidence-based medicine are some of the important individual potentials in the implementation of these cares. There is no evidence indicating Iranian nurses to have these individual potentials. Therefore, the aim of this study was to determination the perceptions of nurses about individual potentials in evidence-based nursing and ...

background: citations are fundamental basis of all scientific papers including theses. inaccurate and improper citations would lead to high expenses for the researchers and libraries to access these citations. this research tried to review the accuracy of references in persian defended medical specialized theses in 2007 in tabriz university of medical sciences, tabriz, iran. it also aimed to de...

BACKGROUND AND AIMS Since most orthodontic patients are children and adolescents, it is believed that teachers can help find these patients and make them aware of their orthodontic problems. Therefore, teachers are expected to have proper knowledge about these problems. The aim of this study was to determine teachers' awareness about orthodontic treatments in Tabriz and Saqqez and compare it in...

BACKGROUND This paper discusses the corrosion and scaling potential of Tabriz drinking water distribution system in Northwest of Iran. Internal corrosion of piping is a serious problem in drinking water industry. Corrosive water can cause intrusion of heavy metals especially lead in to water, therefore effecting public health. The aim of this study was to determine corrosion and scaling potenti...
