Durante la pandemia provocada por el SARS-CoV-2, Escala de Miedo al COVID-19 (FCV-19S) se ha convertido en uno los principales instrumentos psicométricos utilizados investigación a nivel mundial. El presente estudio examinó las propiedades psicométricas versión argentina FCV-19S. Más específicamente, analizó y comparó diferentes modelos posibles con fin determinar qué estructura interna encaja ...

Gingivostomatitis (GS) is a significant condition in cats because of oral discomfort and associated periodontal disease. Several infectious agents have been associated with the presence of GS, but a causal relationship is unclear. The cats in this study were housed together, had a history of flea exposure, and were vaccinated with a modified live FVRCP product. There were nine cats with active ...

This study investigates the economic validity of the diffusion of fuel cell vehicles (FCVs) and all-electric vehicles (EVs), employing a cost-benefit analysis from the social point of view. This research assumes the amount of NOx and tank-to-wheel CO2 emissions and gasoline use reduction as the benefits and the purchase costs, infrastructure expenses, and maintenance costs of alternative vehicl...

This paper presents a series of approaches for discrete time-domain synthesis of conical bore instrument sounds. The generation of steady, selfsustained oscillations using conical waveguides is complicated by properties inherent to truncated conic frusta. Two different physical structures are discussed which can be characterized by the same circuit diagram. A more abstract and flexible “virtual...

We propose an algorithm for interactive ray-casting of algebraic surfaces of high degree. A key point of our approach is a polynomial form adapted to the view frustum. This so called frustum form yields simple expressions for the Bernstein form of the ray equations, which can be computed efficiently using matrix products and pre-computed quantities. Numerical root-finding is performed using B-s...

We present an approach to efficiently reduce shadow map resolution while retaining high quality hard shadows. In the first step, we generate a list of sample points that are seen from the camera and then project these into light space, much like Alias-free Shadow Maps. In the next step, we analyze the list of sample points on the GPU to construct a tight light frustum for shadow rendering. Afte...

The present paper describes a testing method for five-axis machining centers using three-dimensional circular interpolation movement equivalent to cone-frustum cutting. In the present paper, the test conditions, such as the half apex angle of cone-frustum and the sensitive directions of the ball bar device were investigated. In addition, the sensitivity coefficient of each axis was investigated...
