New distribution data on spanish autochthonous species of freshwater fish

Over the last two years (2008-2010) we performed a monitoring project to update the Spanish freshwater fish fauna. We have collected in 785 sampling localities homogeneously distributed throughout Spain each year. We find as the most important result of this study the occurrence of several species that constitute new records for some rivers or basins in Spain: Lampetra planeri, Petromyzon marinus, Barbus haasi,...

Age and growth of the alfonsino Beryx decadactylus (Cuvier, 1829) from the Azor...

Age and growth of the alfonsino Beryx decadactylus from the Azores, Madeira and Canary Islands were studied based on otolith readings. Alfonsino otoliths are thin and show clear annual growth rings. Specimens ranged in size from 21.0 to 50.0 cm fork length (aged 2 to 10 years) in the Azores, 20.0 to 45.0 cm fork length (1 to 11 years) in Madeira, and 21.0 to 44.0 cm fork length (0 to 9 years) in the Canary Isla...

Utilización de compost agotado de champiñón como capa de coberturas en nuevos c...

El objetivo de este trabajo fue evaluar el comportamiento agronómico de seis mezclas de cobertura, elaboradas a partir de sustrato postcultivo del champiñón Agaricus bisporus, en nuevos ciclos de cultivo. Los resultados obtenidos mostraron la viabilidad de la reintroducción del sustrato en nuevos ciclos de cultivo, ya sea como material de base único, si se somete a un proceso de lavado para eliminar sales solub...

Self-Care Behaviors and Health Indicators in Adults with Type 2 Diabetes

This descriptive correlational study aimed to analyze self-care behaviors and their relationship with health indicators represented by glycemic control, lipid profile, Body Mass Index [BMI], waist circumference and body fat percentage in a sample of 98 adults with type 2 diabetes in an area of Nuevo Leon, Mexico (August 2005/May 2006). The results showed a low self-care behaviors index (<img border=0 width=11 h...

New records of grey cutthroat, Synaphobranchus affinis (Actinopterygil: Anguill...

Acta Ichthyol. Piscat. 40 (1): 66–70 ; Following a series of surveys with bottom longlines and fish traps along the island slopes off the archipelagos of Madeira, Canaries and Cape Verde, and with bottom trawls along the coast of Morocco and Western Sahara between 2004 and 2006 many specimens of Synaphobranchus were caught, revealing the presence of two species. Based on these specimens and Museum preserved sp...

Occurrence of hybrids and laboratory evidence of fertility among three species ...

In seven studied communities of Western Mexico, triatomine specimens were sympatrically collected, some with atypical morphological characteristics in contrast to pure specimens, which were presumed to be hybrids. More than 200 specimens of Meccus pallidipennis and Meccus longipennis with brown-yellow markings on dorsal connexival segments were collected in Ahuacapán and Quitupan. In La Mesa, more than 60 speci...

Copper on activated carbon for catalytic wet air oxidation

Textile industry is an important source of water contamination. Some of the organic contaminants cannot be eliminated by nature in a reasonable period. Heterogeneous catalytic wet air oxidation is one of the most effective methods to purify wastewater with organic contaminants. In this work, catalysts based on copper supported on activated carbon were synthesized. The activated carbons were obtained from indust...

Porosity Development in Activated Carbons Prepared from Walnut Shells by Carbon...

The influence of carbon dioxide and steam as activating agents on the porosity development of activated carbons produced from walnut shells was investigated. The study was made covering a wide range of burnoff (12-76%) and employing different temperatures and times: in carbon dioxide activation, 850 °C varying the activation time in the range 60-480 min, and in steam activation, 700, 850, and 900 °C (for 30-120...
