By using remote sensing data, Geographic Information Systems (GIS) provide convenience in determining basin morphology and watershed planning studies. For this aim, the applicability of Arc-GIS software Afrin Bridge Basin by processing Digital Elevation Model (DEM) data hydrological analysis tools parameters (i.e. boundary, variation elevation, drainage area, flow network, slope) were investiga...

It is proved that the crossing number of C6 X Cn is 4n for every n 2: 6. This is in agreement with the general conjecture that the crossing number of Cm x en is (m 2)n, for 3 ::; m :s; n.

A cuspidal curve is a curve whose singularities are all cusps, i.e. unibranched singularities. The article describes computations which lead to the following conjecture: A rational cuspidal plane curve of degree greater or equal to six has at most three cusps. The curves with precisely three cusps occur in three series. Assuming the Flenner–Zaidenberg rigidity conjecture the above conjecture is...

The main aim of this paper is to determine the number cN,D of genus 2 covers of an elliptic curve E of fixed degree N ≥ 1 and fixed discriminant divisor D ∈ Div(E). In the case that D is reduced, this formula is due to Dijkgraaf. The basic technique here for determining cN,D is to exploit the geometry of a certain compactification C = CE,N of the universal genus 2 curve over the Hurwitz space H...

discrimination of regenerative cirrhotic nodules of the liver (cn) from hepatocellular carcinoma (hcc) is sometimes difficult. we examined the utility of agnor staining in this context. fifteen cases of hcc and 25 cases of cn were stained by agnor method and the mean agnor number for one hundred nuclei in each case was determined. there was a significant difference between the mean agnor counts...

The Spreadsheet Tool for the Estimation of Pollutant Load (STEPL) can be used for Total Maximum Daily Load (TMDL) processes, since the model is capable of simulating the impacts of various best management practices (BMPs) and low impact development (LID) practices. The model computes average annual direct runoff using the Soil Conservation Service Curve Number (SCS-CN) method with average rainf...

Surface runoff is a primary driving factor for water regulation services on oil palm plantations as it determines the hydrological components and other biogeochemical process. Therefore, understanding their interaction contribution within watershed system important to support decision-making system. Here, we applied Soil Water Assessment Tools (SWAT) model simulate an intermittent micro-catchme...

The variability of the curve number (CN ) and the retention parameter (S) of the Soil Conservation Service (SCS)-CN method in a small agricultural, lowland watershed (23.4 km2 to the gauging station) in central Poland has been assessed using the probabilistic approach: distribution fitting and confidence intervals (CIs). Empirical CNs and Ss were computed directly from recorded rainfall depths ...
