The F0 larva of Onychogomphus cazuma, of which only the final exuvia was known, is described, and illustrated for the first time, from materials collected in two locations in the Valencian Community (Spain). The morphological characteristics of the larvae are analysed, and a key is built for the determination of the five species of the genus Onychogomphus present in the Iberian Peninsula and the Maghreb. A key is also provided to separate the genus Gomphus from the genus Onychogomphus, without using the palp structure of the prementum. Additional data about the habitat of the species are provided and a protection figure is proposed at the regional level. [ABSTRACT FROM AUTHOR]

Initially known for its deleterious health effects, hydrogen sulfide (H2S) has recently been recognized as a biologically important gas carrier, like nitric oxide and carbon monoxide. H2S is produced endogenously in mammalian cells by enzymatic and non-enzymatic pathways. when it is produced by the enzymatic pathway, its synthesis is carried out from the amino acid L-cysteine through the transsulfuration pathway. It can also be produced endogenously from exogenous compounds that function as H2S donors as, for example, the naturally occurring organic donors found in some plants. Currently, the role of H2S is well known as brain and cardiac protector, and its research as a therapeutic adjuvant in metabolic diseases such as obesity and type-2 diabetes is becoming increasingly important. The objective of this review is to examine how the contribution of donors and precursors of hydrogen sulfide by the diet impacts health and disease. [ABSTRACT FROM AUTHOR]

Yield stress as a function of water content for soils prone to debris flows due to rain is studied in this work. Yield stress is calculated by the slump test in cylindrical geometry by using the relation proposed by Pashias et al. (1996). The advantage of using this method is the quick and easy determination of yield stress. In this case, the test can be done in situ in the zone susceptible to debris flows. Results of yield stress variation as a function of water content are shown for the cerro de Xico zone located in Chalco Valley in México State, which is considered to be vulnerable to landslides by the local authorities.

The present document tries to explain the presence of the denominated Latin American peripheral scientific journals, from an analysis that provides the cover of institutional, technical aspects and of the impulse for the use of information technologies and communication in the alluded journals, taking as a sample five Latin American countries in six specific areas of knowledge. Also, it formulates a series of conclusions and feasible recommendations for possible solutions. [ABSTRACT FROM AUTHOR]

This paper develops a comprehensive comparative and empiric study conducted in four medium size factories belonging to the industrial machinery production. The analysis of the productive processes will be used by the author to interpret the organizational structures resulted from the implementation of modernization policies in the different factories.

Como consecuencia de las reformas estructurales de los primeros años de la década de los noventa, el Perú ha logrado revertir la tendencia decreciente de las exportaciones observada durante la segunda mitad de los ochenta. Además, en 1998 se ha incorporado al APEC, hecho que representa un conjunto de posibilidades para el desarrollo del intercambio comercial. En este artículo se busca identificar qué tipo de productos se han beneficiado de este proceso de reformas y cuáles dependerán, con mayor intensidad, del desarrollo de las potencialidades actuales. Asimismo, se trata de establecer qué factores productivos explican estos resultados. Para ello se efectúan estimaciones econométricas, basadas en un modelo del tipo Hecksher-Ohlin ampliado, a una muestra de países del APEC. Los resultados indican que si bien factores como el stock de capital, el área geográfica y la disponibilidad de tierras para el cultivo y la actividad forestal son significativos para explicar la dinámica de las exportaciones, hay otros en los cuales el gobierno puede influir directamente, como el grado de apertura y el nivel educativo de la población.
