To investigate climatic, spatial, temporal, and environmental patterns associated with hantavirus pulmonary syndrome (HPS) cases in the Four Corners region, we collected exposure site data for HPS cases that occurred in 1993 to 1995. Cases clustered seasonally and temporally by biome type and geographic location, and exposure sites were most often found in pinyon-juniper woodlands, grasslands, ...

A newly identified hantavirus, tentatively called Four Corners virus (FCV), was found to be the aetiological agent of a 1993 outbreak of hantavirus pulmonary syndrome (HPS) in the southwestern United States. Immunodominant epitopes of 43 and 31 amino acids were identified in the nucleocapsid protein and G1 glycoprotein, respectively. The G1 genes of different hantaviruses are highly divergent, ...

Hantavirus cardiopulmonary syndrome (HCPS), a rodent-borne zoonosis, has been endemic in the Americas for at least several decades. It is hypothesized that the 1991-1992 El Niño-southern oscillation (ENSO) caused increased precipitation that allowed an increase in rodent population densities, thereby increasing the possibility of transmission to humans. The result was a 1993-1994 outbreak of th...

Fatigue strength is largely affected by the influence of discontinuities: geometric notches like holes and corners in components, surface (roughness), pores inclusions material. Therefore fatigue structures materials a local problem calculations are best carried out using approaches such as stress concept, strain concept or fracture mechanical concepts. In this investigation, discontinuities on...

In this paper, we introduce a general theory of corner rings in noncommutative rings that generalizes the classical notion of Peirce decompositions with respect to idempotents. Two basic types of corners are the Peirce corners eRe (e2 = e) and the unital corners (corners containing the identity of R). A general corner is both a unital corner of a Peirce corner, and a Peirce corner of a unital c...

Four experiments were conducted with rats in order to determine whether being placed on a platform in one corner of a rectangular swimming pool results in latent spatial learning. Rats in Experiments 1-3 received four trials a day of being placed on the platform. During a subsequent test trial, in which they were released into the pool without the platform, the rats exhibited a preference for s...

This paper presents a wideband eight-port multiple-input-multiple-output (MIMO) circularly polarized antenna system for mm-wave applications. The proposed element is an L-shape microstrip line with series fishtail stubs on one side. spacing between these adjusted to be guided wavelength at the center frequency. These are used cancel anti-phase magnetic currents enhance radiated fields from line...

The aim of the present study is to compare the needs proposed by the interpersonal-psychological theory of suicide (IPTS) and the suicide as psychache (SAP) theory in their ability to predict lethal suicidal behavior. Utilizing a sample of 38 suicide notes from both fatal and non-fatal suicides, graduate student raters examined the presence of the thwarted needs proposed by both theories. None ...
