The phase constitution of the Nd16(Fe1–xAlx)76B8 permanent magnets alloys for 0.0≦x≦0.20 is studied by means of thermomagnetic analysis and Mossbauer spectroscopy. A second magnetic phase with a Curie temperature of 170 °C coexists with Al doped hard magnetic boride for...

Haiti has historically vaccinated between 100,000 and 300,000 dogs annually against rabies, however national authorities have not been able to reach and maintain the 70% coverage required to eliminate the canine rabies virus variant. Haiti conducts massive dog vaccinati...

Progress in immunotherapy revolutionized the treatment landscape for advanced lung cancer, raising survival expectations beyond those that were historically anticipated with this disease. In the present study, we describe the methods for the adjustment of mixture parame...

The influence of the addition of Cu in the YCo/sub 5/ matrix, YCo/sub 5-x/Cu/sub x/ with 0/spl les/x/spl les/3, on magnetic and structural properties was investigated. With increasing Cu concentration a decreasing saturation magnetization, anisotropy energy and Curie te...

During the search process of differential evolution (DE), each new solution may represent a new more promising region of the search space (exploration) or a better solution within the current region (exploitation). This concurrent exploitation can interfere with explora...

A partir de las trasformaciones que las TIC han provocado en todas las esferas de la sociedad, se le ha atribuido gran importancia a la alfabetización digital de los docentes de las escuelas de hotelería y turismo, tanto internacionalmente como en nuestro territorio. Si...

Resumen Se propone un método para el cálculo de la presión mínima central en un modelo de intensidad potencial de ciclones tropicales determinado a partir del perfil radial de viento de Willoughby, lo que garantiza una relación físicamente directa entre la presión mínim...

The main component of the Center for Genetic Engineering and Biotechnology (CIGB) candidate vaccine against Hepatitis C virus (HCV) is the pIDKE2 plasmid.The current designed downstream process for the production of pIDKE2 fulfils all regulatory requirements and renders...

Derivatives play an important role in social and economic studies. They describe the behavior of conditional expectations. Once a phenomena is characterized by parametric specifications, the conditional expectation m(x) may be modeled by a regression function. Then, der...

The Finger-to-nose test (FNT) is an accepted neurological evaluation to study the coordination conditions. In this work, a methodology for the analysis of data from FNT is proposed, aimed at assessing the evolution of the condition of Spinocerebellar Ataxia type 2 (SCA2...
