An update on feline infectious peritonitis: diagnostics and therapeutics.

This review is concerned with what has been learned about feline infectious peritonitis (FIP) diagnostics and therapeutics since the publication of an extensive overview of literature covering the period 1963-2009. Although progress has been made in both areas, obtaining a definitive diagnosis of FIP remains a problem for those veterinarians and/or cat owners who require absolute certainty. This review will cover both indirect and direct diagnostic tests for the disease and will emphasize their limitations, as well as their specificity and sensitivity. There is still no effective treatment for FIP, although there are both claims that such therapies exist and glimmers of hope coming from new therapies that are under research. FIP has also been identified in wild felids and FIP-like disease is now a growing problem among pet ferrets

Field-induced dissociation of two-dimensional excitons in transition-metal dichalcogenides

Generation of photocurrents in semiconducting materials requires dissociation of excitons into free charge carriers. While thermal agitation is sufficient to induce dissociation in most bulk materials, an additional push is required to induce efficient dissociation of the strongly bound excitons in monolayer transition-metal dichalcogenides (TMDs). Recently, static in-plane electric fields have proven to be a promising candidate. In the present paper, we introduce a numerical procedure, based on exterior complex scaling, capable of computing field-induced exciton dissociation rates for a wider range of field strengths than previously reported in literature. We present both Stark shifts and dissociation rates for excitons in various TMDs calculated within the Mott-Wannier model. Here, we find that the field induced dissociation rate is strongly dependent on the dielectric screening environment. Furthermore, applying weak-field asymptotic theory (WFAT) to the Keldysh potential, we are able to derive an analytical expression for exciton dissociation rates in the weak-field region

On the domain of the assembly map in algebraic K-theory

We compare the domain of the assembly map in algebraic K-theory with respect to the family of finite subgroups with the domain of the assembly map with respect to the family of virtually cyclic subgroups and prove that the former is a direct summand of the later.Comment: Published by Algebraic and Geometric Topology at http://www.maths.warwick.ac.uk/agt/AGTVol3/agt-3-35.abs.htm

Rate of Advance and Infiltration on Furrow Irrigated Blencoe Soils in Southeastern South Dakota

The irrigation of the earth has been practiced since the earliest history of man. Historically, civilization has followed the development of irrigation. The antiquity of irrigation is well documented throughout the written history of mankind. The bible talks of irrigation in the book of Genesis where the laws of Hammurabi indicates to the people that they had to depend on irrigation for existence. Irrigation canals supposed to have been built before 2000 B.C. are still delivering water in the valleys of the Nile. The success of early kings in China was measured by their wisdom and progress in water-control activities. Irrigation ideas and practices were brought to the United States by the early Spanish missionaries. No effort was made to develop and agricultural economy based on irrigation until 1847 when Mormons entered the Salt Lake Valley. The importance of irrigation in the world today was well stated by N.D Gulhali of India: “Irrigation in many countries is an old art as old as civilization but for the whole world it is a modern science- the science of survival.” Irrigation can generally be defined as the application of water to the soil for the purpose of supplying the moisture essential for plant growth. Irrigation may be accomplished in four different ways: flooding, furrows, sub-irrigation and sprinkling

Circulating and organizational testosterone and the perception of dominance

This project focused on the relationship between both circulating testosterone (T), prenatal exposure to T, and perception of emotions in the faces of others. Based on past research, Twas hypothesized to be related to the Theory of Mind (ToM) abilities, which are concerned with reading emotions and intentions of others. More specifically, T was hypothesized to be more strongly related to the perception of dominant emotions compared to the perception of non-dominant emotions. To test this idea, the Test of the Eyes was used, which measures the ability to correctly perceive emotions in pictures of faces (specifically, eyes). To date, this research was the first to examine both circulating T and an indicator of prenatal T in relation to the perception of dominance. Correlational analyses showed that neither exposure to prenatal T, nor circulating T, were related to scores on the ToM test. Consistent with past research, however, women scored better on the test, interpreting emotions better than men. Several different measures of trait dominance were found to be positively related to circulating T, but this relationship was accounted for by gender. Trait dominance was also unrelated to organizational T and to the perception of dominance. Findings, limitations, and future research directions are discussed
