Development of a genetic method to estimate effective spawner numbers in the NPF and Queensland tiger prawn fisheries

OBJECTIVES: 1. To critically evaluate a variety of mathematical methods of calculating effective population size (Ne) by conducting comprehensive computer simulations and by analysis of empirical data collected from the Moreton Bay population of tiger prawns. 2. To lay the groundwork for the application of the technology in the NPF. 3. To produce software for the calculation of Ne, and to make it widely available.

Growth hormone therapy in Prader-Willi Syndrome

Prader-Willi syndrome (PWS) was originally described less than 50 y ago,1 although reference to children with characteristics of the syndrome are to be found in other literature previous to this.2 Until relatively recently the diagnosis was made upon the clinical features as outlined by Holm,3 which include severe muscular hypotonia in the neonatal period leading to feeding difficulties and undernutrition, hypogonadism and later hyperphagia and obesity. Latterly the syndrome has been identified as being associated with an interstitial deletion of the q11-13 region on chromosome 15.4 In the majority of cases the deletion is in the paternally derived chromosome. In the remainder of cases there seems to be a failure to inherit the entire paternal chromosome and as a consequence both the chromosomes inherited are maternal, thus leading to maternal disomy.

Ligand K-edge X-ray absorption spectroscopy and DFT calculations on [Fe3S4]0,+ clusters: delocalization, redox, and effect of the protein environment

Ligand K-edge XAS of an [Fe3S4]0 model complex is reported. The pre-edge can be resolved into contributions from the í2Ssulfide, í3Ssulfide, and Sthiolate ligands. The average ligand-metal bond covalencies obtained from these pre-edges are further distributed between Fe3+ and Fe2.5+ components using DFT calculations. The bridging ligand covalency in the [Fe2S2]+ subsite of the [Fe3S4]0 cluster is found to be significantly lower than its value in a reduced [Fe2S2] cluster (38% vs 61%, respectively). This lowered bridging ligand covalency reduces the superexchange coupling parameter J relative to its value in a reduced [Fe2S2]+ site (-146 cm-1 vs -360 cm-1, respectively). This decrease in J, along with estimates of the double exchange parameter B and vibronic coupling parameter ì2/k-, leads to an S ) 2 delocalized ground state in the [Fe3S4]0 cluster. The S K-edge XAS of the protein ferredoxin II (Fd II) from the D. gigas active site shows a decrease in covalency compared to the model complex, in the same oxidation state, which correlates with the number of H-bonding interactions to specific sulfur ligands present in the active site. The changes in ligand-metal bond covalencies upon redox compared with DFT calculations indicate that the redox reaction involves a two-electron change (one-electron ionization plus a spin change of a second electron) with significant electronic relaxation. The presence of the redox inactive Fe3+ center is found to decrease the barrier of the redox process in the [Fe3S4] cluster due to its strong antiferromagnetic coupling with the redox active Fe2S2 subsite.

A generic treatment of Alismatidae in the Neotropics with special reference to Brazil

A Subclasse Alismatidae nos neotrópicos é composta de nove famílias com 11 gêneros das quais, nove ocorrem na bacia amazônica e cinco no Brasil extra-amazônico. Apenas duas famílias não estão presentes no Brasil e mais duas ausentes da Amazônia brasileira. Este trabalho apresenta descrições detalhadas das famílias e gêneros, além de comentários sobre distribuição geográfica dos gêneros. As famílias estão organizadas na sequência sistemática que nós aceitamos. Os gêneros de cada família estão organizados em ordem alfabética i=sem significado sistemático. Fornecemos desenhos de pelo menos um gênero para cada família. Referências importantes -- tais como revisões genéricas, levantamentos da literatura, ou monografias de áreas neotropicais — estão relacionadas no início de cada tratamento a nível de família. As excelentes coleções do Projeto Flora Amazônica foram de importância decisiva para nosso trabalho-, sem elas não poderiamoi fazer um tratamento genérico completo para toda a região neotrópica.

Observatorio de gestión del riesgo de desastres para la provincia de Córdoba.

A través de la presente investigación, se procura organizar un Observatorio de Gestión de Riesgo de Desastres para la Provincia de Córdoba como un espacio de interacción entre la investigación académica y las prácticas políticas y ciudadanas en torno a los temas de gestión de riesgo desde la perspectiva de la seguridad humana. A través de las actividades realizadas por el Observatorio, tanto teóricas como prácticas, se intentará monitorear: 1. las políticas públicas sobre la gestión de riesgo de desastres de la Provincia de Córdoba (todos aquellos planes, programas y proyectos); 2. la preparación y administración de las emergencias y de los riesgos de desastres de la Provincia de Córdoba (latentes y manifiestos); 3. las prácticas ciudadanas de la Provincia de Córdoba en torno a la temática (percepción del riesgo y la participación de la gestión del riesgo); Este monitoreo busca como fin evaluar críticamente los tópicos antes mencionados con vistas a futuras recomendaciones y/o asesoramiento para la implementación de políticas públicas. Asimismo, el Observatorio funcionaría como un ámbito propicio para la generación de conocimiento y de pensamiento crítico acerca de la cultura del riesgo en la sociedad cordobesa.

Capacidades institucionales y gestión local del riesgo de desastres: el caso de la ciudad de Córdoba.

La Gestión del Riesgo de Desastres es una una temática actual en nuestra sociedad y en el mundo moderno, y que en la Ciudad de Córdoba tiene una incumbencia particular debido a la importancia del nivel local de gobierno en este temática. A través de la presente investigación se procura realizar un diagnóstico de las capacidades institucionales del Gobierno de la Ciudad de Córdoba para la Gestión del Riesgo de Desastres, pensado como un espacio de interacción entre la investigación académica, y las prácticas políticas y ciudadanas en torno a los temas de gestión de riesgo desde la perspectiva de la seguridad humana. A partir de ello se intentará identificar: 1. las políticas públicas que orienten hacia la gestión del riesgo de desastres a nivel local (todos aquellos planes, programas y proyectos). 2. la preparación y administración de las emergencias y de los riesgos de desastres de la Ciudad de Córdoba (latentes y manifiestos). Este diagnóstico tiene como fin evaluar críticamente los tópicos antes mencionados con vistas a futuras recomendaciones y/o asesoramiento al Gobierno de la Ciudad de Córdoba para la implementación de políticas públicas. Asimismo, el grupo busca funcionar como un ámbito propicio para la generación de conocimiento y de pensamiento crítico acerca de la cultura del riesgo en la sociedad cordobesa.

Development of a rehabilitation system for the red mud waste generated at the Aughinish Alumina Bayer Plant

Aughinish Alumina Limited (AAL) have an obligation by terms of their Integrated Pollution Control Licence (IPCL) and Planning Permission to establish vegetation on the red mud stack at their plant at Aughinish, Co. Limerick. High pH and high exchangeable sodium percentage are the main known factors limiting the establishment of vegetation on red mud. Gypsum addition has been known to assist in alleviating these problems in other countries. However, there is no experience or published information on red mud rehabilitation under Irish conditions. Red mud with organic and inorganic waste-derived ameliorants as well as selected grassland species were examined under laboratory controlled environment conditions as well as in field plot trials. Also, in order that it would be economically achievable, the research utilised locally available waste products as the organic amendments. Screening trials found that physical constraints severely limit plant germination and growth in red mud. Gypsum addition effectively lowers pH, exchangeable sodium percentage and the availability of A1 and Fe in the mud. A strong relationship between pH, ESP and A1 levels was also found. Gypsum addition increased germination percentages and plant growth for all species investigated. Greenhouse trials demonstrated that organic wastes alone did not greatly improve conditions for plant growth but when used in conjunction with gypsum plant performances for all species investigated was significantly increased. There was a high mortality rate for grasses in non-gypsum treatments. An emerging trend of preferential iron uptake and calcium deficiency in non-gypsum treatments was found at pot screening stage. Species also displayed manganese and magnesium deficiencies.
