Echocardiograms of high quality were obtained in 26 patients with classic or definite rheumatoid arthritis by the criteria of the American Rheumatism Association, but with no evidence of overt heart disease. The echocardiograms were analyzed for evidence of pericardial disease. The E-to-F slope was determined to assess the mitral valve, and multiple jadices of left ventricular performance were ...

We report a series of high-resolution N-body simulations designed to examine the internal physical properties of dark matter halos. A total of fifteen halos, each represented by ∼ 1 million particles within the virial radius, have been simulated covering the mass range of 2 × 10 ∼ 5 × 10hM⊙. As the first application of these simulations, we have examined the density profiles of the halos. We fo...

Overarching goal of this paper was to evaluate automated and semi-automated methods of mapping wetlands using Landsat ETM+ and SRTM data. Automated methods consisted of: (a) slope derived from SRTM, (b) Tasseled cap Wetness Index (TCWI), (c) Normalized Difference Water Index (NDWI), (d) multi-band vegetation indices (MBVIs), (e) two band vegetation indices (TBVIs), (f) normalized difference veg...

PURPOSE We previously reported that analysis of histologically normal intestinal epithelium for spectral slope, a marker for aberrations in nanoscale tissue architecture, had outstanding accuracy in identifying field carcinogenesis in preclinical colorectal cancer models. In this study, we assessed the translatability of spectral slope analysis to human colorectal cancer screening. METHODS Su...

this research was conducted to zoning of gorgan agricultural lands for hulless barley cropping using evaluation of some environmental factors base on boolean logic and by geographic information system. for this purpose, agro-ecological requirements of hulless barley firstly, identified according to scientific resources. rating and thematic requirement maps were then provided. studied environmen...

due to the different factors and complexity of their effects on healthy and sustainability of urban forest, this study has been tried by means of determining effective factors in ecosystem, and dividing sorkhe hesar man made forest park to homogeneous units according to natural factors (slope, aspect, high, soil depth, mixture and pure planting system) and human factors (amount of irrigation an...

Echocardiographic studies were performed in 23 hypertensive patients who were receiving therapy with long-term hemodialysis. Five patients (22 percent) had normal thickness of the left ventricular wall. Eleven (48 percent) had symmetric left ventricular hypertrophy, and seven (30 percent) showed asymmetric septal hypertrophy, with a ratio of septal to posterior wall thickness of 1.3 or greater....

1. introduction although solar energy is one of the important renewable, free and clean energy sources, constant exposure to the sun, especially uv radiation, can lead to some problems. these problems include skin diseases, loss of pregnancy, permanent or temporary infertility, and cataracts (strom, 2003), weak immunity system, and an increased risk of diseases especially in children (hoyos-bac...

Plot data from the USFS FIA program could be combined with terrain variables to attempt to explain how terrain characteristics influence forest growth, species composition, productivity, fire behavior, wildlife habitat, and other phenomena. While some types of analyses using FIA data have been shown to be insensitive to precision of plot locations, it has been suggested that terrain-based model...
