Nanotechnology in food industry II: risk assessment and legislation

Currently, there is increasing use of nanomaterials in the food industry thanks to the many advantages offered and make the products that contain them more competitive in the market. Their physicochemical properties often differ from those of bulk materials, which require specialized risk assessment. This should cover the risks to the health of workers and consumers as well as possible environmental risks. The risk assessment methods must go updating due to more widespread use of nanomaterials, especially now that are making their way down to consumer products. Today there is no specific legislation for nanomaterials, but there are several european dispositions and regulations that include them. This review gives an overview of the risk assessment and the existing current legislation regarding the use of nanotechnology in the food industry.

El discernimiento de espíritus en las periferias cristianas: gozo, pactos y poderosos entre aborígenes evangélicos del Chaco Argentino

El discernimiento de espíritus ha sido a lo largo de la historia del cristianismo un mecanismo fundamental para el control del acceso al carisma. Su desarrollo ha estado profundamente ligado a los cambios en la estructura social de las iglesias. Por ello buscamos aportar nuevas miradas sobre este dispositivo, analizándolo en el contexto de las periferias cristianas. Específicamente centraremos nuestro análisis en las iglesias evangélicas aborígenes mocoví del suroeste de la provincia del Chaco en Argentina. Nos aproximaremos a estas cuestiones a partir del análisis a la estructura social de estas iglesias, sus concepciones sobre los vínculos con las potencias no-humanas, la gestión de salud y enfermedad y la experiencia del culto.
