It is well known that wrist pulse signals contain information about the status of health of a person and hence diagnosis based on pulse signals has assumed great importance since long time. In this paper the efficacy of signal processing techniques in extracting useful information from wrist pulse signals has been demonstrated by using signals recorded under two different experimental conditions viz. before lunch condition and after lunch condition. We have used Pearson's product-moment correlation coefficient, which is an effective measure of phase synchronization, in making a statistical analysis of wrist pulse signals. Contour plots and box plots are used to illustrate various differences. Two-sample t-tests show that the correlations show statistically significant differences between the groups. Results show that the correlation coefficient is effective in distinguishing the changes taking place after having lunch. This paper demonstrates the ability of the wrist pulse signals in detecting changes occurring under two different conditions. The study assumes importance in view of limited literature available on the analysis of wrist pulse signals in the case of food intake and also in view of its potential health care applications.

The current study analysed how the climbing perch Anabas testudineus an air-breathing freshwater fish make choice when a pair of food patches differing in the gain is presented. The results revealed no significant variation in the preference towards the patch of food material cumulated in one place over the same amount of food dispersed in a wider area and located at an equal distance. Additionally, enhancement of the value of dispersed or cumulated patch, by moving it towards the subject fish (spatial discounting) was also found to be ineffective in influencing the food patch utilisation in this species.

El presente trabajo fue realizado en las empresas procesadoras de frutas tropicales de Nicaragua que han venido desarrollando actividades encaminadas a la certificación HACCP según datos suministrados por el Ministerio Agropecuario y Forestal (MAG-FOR), las empresas visitadas fueron: APRONOT, ubicada en el Municipio de San Marcos Departamento de Carazo, La empresa Callejas Sequeira, S.A. ubicada en la ciudad de Granada, La empresa Exotic Food ubicada en el Km 107 carretera a Rivas y la empresa TROPIFRUTAS ubicada en Nueva Guinea, Región Autónoma del Atlántico Sur. Se consultaron fuentes secundarías existentes en el país sobre el Análisis de Riesgos y Críticos Puntos de Control (HACCP), así como información de Internet. Para conocer la situación actual del proceso de certificación y adopción del Análisis de Riesgos y Críticos Puntos de Control (HACCP) en la Industria Agroalimentaria se procedió a entrevistar a funcionarios del Ministerio Agropecuario y Forestal (MAGFOR), y del Ministerio de Fomento, Industria y Comercio (MIFIC). La industria agroalimentaria de Nicaragua ha adoptado el sistema de Análisis de Riesgos y Críticos Puntos de Control (HACCP) y se encuentra en un proceso de verificación y Auditoria para obtener la certificación, todas las empresas entrevistadas mostraron toda la voluntad de certificar su producto ya que les abre las puertas en la búsqueda de mejores oportunidades de mercados para sus productos. Las mayores dificultades para lograr la certificación radican en la falta de recursos financieros para ejecutar las recomendaciones de los inspectores, así como la dificultad de garantizar la trazabilidad del origen de la materia prima.

This research addresses product introduction dispersed across locations and companies. Mechanisms appropriate to integrate activities in collocated teams may not serve dispersed teams well. A semiconductor design licensor was studied in depth to explore how dispersed product introduction varies with uncertainty. We found that autonomous teams focused on sub-products (micro-products) were used rather than cross-functional teams in departments with high architectural uncertainty. Both types of teams were effectively dispersed across locations and companies. This suggests that small high-technology companies may find it easier to expand into new geographies and product lines than was previously believed.
