Digital Elevation Models (DEMs) are used to estimate different morphologies, analysis of river profile, delineating drainage basin and drainage pattern associated with lithological and structural changes. The study area is Maroon River located in Khuzestan Province, Iran. In this study geomorphometric analysis based on DEM carried out to understand Maroon river uplift rate and tectonic- erosion...

Ultra-precise reflective and diffractive optical elements like blazed diffraction gratings or ultra-precise mirrors of flat, elliptic, parabolic, or other shapes have become key components in today’s synchrotron optics. These optical components feature nanometre accuracy on a macroscopic length scale. Beamlines with extreme lengths of 100m to 1km or more (as planned for the European XFEL) will ...

Rangelands worldwide have more shrubs now, and subterranean rangeland rodents show close interaction to shrubs when choosing a burrowing site. The study was conducted in Otindag Sandy Land in Inner Mongolia, China with the objective of determining the effects of slope position on spatial pattern and interaction of shrubs; how rodents choose their habitat in different slope; and shrubs and roden...

This article studied the effects of resolution on elevation and slope using Statistical and Geostatistical methods. Xian' Nan watershed in Loess Plateau was taking as the study area. The base data was a 1:10000 topographic map and the resolutions studied in this paper included 5 m, 25 m and 50 m. The results showed that: (1) for elevation and slope data, the mean value, STD value, histogram and...

Indigenous people have used architecture over millennia to adapt climatic factors and achieve stable comfortable living. These adaptations can still inform the design of contemporary regional architecture. In order explore relationship between traditional dwellings factors, we examine buildings in four provinces cities southwest China. A database was created using detailed data obtained from li...

as the millisecond increase in cycle length per mm Hg rise in systolic pressure. The slope is an index of baroreflex sensitivity and was found to have an average value of 12.8 in 18 subjects without hypertension and 2.8 in 12 others with hypertension. When all results were pooled, there was an inverse relationship between the resting mean arterial pressure and slope of the baroreflex regression...

We evaluated the effects of pressure loading produced by gradual aortic occlusion on left ventricular (LV) myocardial contractility by assessing changes in the slope of the LV end-systolic force-diameter (Fes-Des) relation. Eleven adult mongrel dogs were prepared with ultrasonic crystals for measuring LV diameter and a micromanometer for measuring LV pressure. Preload was decreased by vena cava...

Slope length is an important topographic factor for controlling soil erosion. There exists limited knowledge of the interactions slope length, vegetation restoration, and rainfall intensity on This study investigated impact erosion different grass coverages intensities via simulated experiments. The experiments included five treatments (1, 1.5, 2, 2.5, 3 mm min?1), four cover (0%, 30%, 60%, 90%...

A high-power diode-cladding-pumped Ho³⁺-doped fluoride glass fiber laser operating in cascade mode is demonstrated. The ⁵I₆→⁵I₇ and ⁵I₇→⁵I₈ laser transitions produced 0.77 W at a measured slope efficiency of 12.4% and 0.24 W at a measured slope efficiency of 5.2%, respectively. Using a long fiber length, which forced a large threshold for the ⁵I₇→⁵I₈ transition, a wavelength of 3.002 μm was mea...
