flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
Gully erosion and sedimentation have high priority in Fars Province due to the losses from destruction of lands, roads and civil structures. In the present study, in order to evaluate the threshold for the development and initiation of gully topography in Fars province, two regions were selected including Allamarvdasht, Lamerd and Fedagh, Larestan. 30 gullies were selected in each mentioned are...
Report keratoconus in two patients with a long history of wrestling without any risk factor for corneal ectasia and reviewing the possible pathogenesis. To confirm suspicion of keratoconus, corneal topography was performed using scanning slit topography system and Orbscan. In two wrestlers with the complaint of visual loss in their eyes and IOP raising, corneal topography was performed and de...
Aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology. Consecutive 100 stroke patients with aphasia admitted in Valie Asr hospital, Khorasan in 2003 enrulled in this prospective study. Diagnosis of stroke and aphasia was made by a neurolosist and topograph...
Introduction: Aphasia is a common manifestation of stroke and evaluation of relationships of aphasia and brain topography could lead to better understanding of cognitive neurophysiology. Methods: 100 stroke patients with aphasia admitted in Valie-Asr hospital, Khorasan since April 2003 were enrolled in this prospective cross-sectional study. Diagnosis of stroke and aphasia was made by a neurol...
A model is proposed that will allow forest and land use policy options to be explored in a repeatable, objective and quantitative way. Construction and use of the model should lead to a better understanding of spatial and temporal land use patterns. It will provide detailed spatially-explicit data on a range of parameters to enable rigorous testing and offer insights for further development. Th...
Continued Reforestation and Urban Expansion in the New Century of a Tropical Island in the Caribbean
Accurate and timely monitoring of tropical land cover/use (LCLU) changes is urgent due to the rapid deforestation/reforestation and its impact on global land-atmosphere interaction. However, persistent cloud cover in the tropics imposes the greatest challenge and retards LCLU mapping in mountainous areas such as the tropic island of Puerto Rico, where forest transition changed from deforestatio...
2) Section 1, line 84: “in the study the relationship of the temporal and spatial variation of soil moisture is determined by establishing its controlling factors . . .” The sentence is revised as “in this study the relationship between variation of soil moisture and its controlling factors (e.g. topography and precipitation) is established.” That mean the modified wetness index. Line 110: “. ....
