Three-dimensional mapping products in the form of DEMs (Digital Elevation Models) have become much more accessible in recent years, in part due to the implementation of LIDAR and IFSAR technologies. While there is considerable familiarity with one technology or the other, they are not often examined in terms of their mutually similar characteristics or equally those that are dissimilar. The pur...

An approach for regional low flow frequency analysis is to use multiple regression techniques for obtaining relationships between low flows with specific return periods and catchments characteristics. In this paper, this method has been used. After single-site frequency analysis for 20 stream gauging stations, homogeneity test was performed. Regional relationships between low flows with return ...
in order to determine optimum landuses (in accordance with natural capability) and improve the current land management, landuse planning process was applied by using gis. within the framework of system analysis approach basic ecological and socio-economic , data were mapped. the mapped data were digitized and imported to idrisi and arc/info to build a database ,along with other descriptive data...
if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...
Plastics are an environmental threat; however, their fate once in the pelagic environment is poorly known. We compare results from assessments of floating plastics South Pacific Ocean with accumulated beach Henderson Island. also plastic mass on during 2015 and 2019 investigate presence nanoplastics. There were differences between size classes plastics, increase microplastics (0.33–5 mm) 2019. ...
Aims. SPIRou is a near-infrared (nIR) spectropolarimeter at the CFHT, covering YJHK nIR spectral bands (980?2350 nm). We describe development and current status of wavelength calibration in order to obtain precise radial velocities (RVs) nIR. Methods. make use UNe hollow-cathode lamp Fabry-Pérot étalon calibrate pixel-wavelength correspondence for SPIRou. Different methods are developed identif...
abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
S ubstantial intellectual and financial resources have been invested in the quest to reduce outcomes in patients with ST elevation myocardial infarction (STEMI) through improved pharmacological and mechanical reperfusion therapies. By contrast, little emphasis has been placed on enhancing the medical systems whereby these treatments are delivered, especially as it relates to pre-hospital reperf...
In processing raster digital elevation models (DEMs) it is often necessary to assign drainage directions over flats—that is, over regions with no local elevation gradient. This paper presents an approach to drainage direction assignment which is not restricted by a flat’s shape, number of outlets, or surrounding topography. Flow is modeled by superimposing a gradient away from higher terrain wi...
