The Oldman River watershed in southern Alberta, Canada, is an extensively irrigated region in which intensive agricultural practices have flourished. Concern over water quality in the basin has been expressed because of high levels of enteric disease indigenous to the region. To address these concerns, we conducted a 2-year study to estimate the prevalence of Escherichia coli O157:H7 and Salmon...

Introduction Due to the unprecedented speed of temperature change expected over the course of the 21st century and the lack of direct experience from past changes, models are used to assess the impacts of different scenarios of climate change. Recent research, however, revealed that inconclusive outputs of ecosystem models may occur as a result of instable model dynamics [1-3]. This research pr...

We describe a method to obtain the principal components of a multispectral image. It allows a simultaneous radiometric enhancement by means of a suitable finer level quantization that does not introduce artifacts. Using this method we are able to produce good photographic prints pf the principal components of LANDSAT MSS images. As a matter of fact the twn first components (that we call bands A...

Compilation of almost 200 new maximum horizontal stress (SHmax) orientations in Texas reveals a complex intraplate stress field. A large extensional stress province is associated with extensive growth faulting from northeastern Mexico to Louisiana. SHmax is subparallel to the coastline, following the strikes of the growth faults. In contrast, we observe a strike-slip/normal faulting regime with...

The main aim this paper was efficiency assessment environmental variables construction system Iran. Using geographical information (GIS) statistical method receiver operation characteristic (ROC), 20 assessed based on divisions 30 major hydrological basi...

This paper uses two-dimensional Finite Element Method (FEM) numerical modeling to analyze the orientation of maximum horizontal tensional stress of the Barapukuria coal basin in Bangladesh. An elastic plane stress model incorporating elastic rock physical properties for the coal basin area was used consisting of 2916 elements with a network of 1540 nodes. The stress field at any point of the mo...

[1] Although it is centered in northwestern Mexico, the Mexican monsoon also has been shown to impact portions of the southwestern United States. To provide more information about the spatial distribution of monsoonal impacts in the Southwest, this study employed multiple linear regression modeling to reduce local topographic impacts on monsoonal precipitation to reveal intense monsoonal activi...
