Abstract Pfister, D. H.; R. Healy, G. Furci, A. Mujic, E. Nouhra, C. Truong, M. V. Caiafa & M. E. Smith. 2022. A reexamination and realignment of Peziza sensu lato (Pezizomycetes) species in southern South America. Darwiniana, nueva serie 10(1): 148-177. In this study we review recent collections and historical records of epigeous members of the Pezizales formerly placed in the large, heterogenous genus Peziza from temperate southern South America. Recent analyses using molecular phylogenetic methods allow placement of these species in several previously described genera in recognition of the heterogeneity of Peziza. We include species in nine genera, describe one new species (Peziza gamundiae sp. nov.), and propose one new combination (Phylloscypha nothofageti comb. nov.). We also demonstrate that Pustularia microspora is a synonym of the previously described taxon Peziza pseudosylvestris. Our purpose is to draw attention to these taxa in order to promote their collection and study in a modern framework.
Resumen Pfister, D. H.; R. Healy, G. Furci, A. Mujic, E. Nouhra, C. Truong, M. V. Caiafa & M. E. Smith. 2022. Un reexamen y revisión de las especies de Peziza sensu lato (Pezizomycetes) en el cono sur de Sudamérica. Darwiniana, nueva serie 10(1): 148-177. En este trabajo hemos revisado material fresco y colecciones históricas de Pezizales epigeos formalmente incluidos en el amplio y heterogéneo género Peziza provenientes de las zonas templadas del sur de Sudamérica. Estudios recientes basados en filogenias moleculares han permitido posicionar estas especies en varios géneros previamente descritos demostrando su heterogeneidad. Incluimos aquí especies de nueve géneros, una especie nueva para la ciencia (Peziza gamundiae sp. nov.) y proponemos una nueva combinación (Phylloscypha nothofageti comb. nov.). También demostramos que Pustularia microspora es sinónimo de un taxón previamente descrito como Peziza pseudosylvestris. Nuestro objetivo es llamar la atención sobre la presencia de estos taxa para promover su recolección y estudio en trabajos científicos modernos.

RESUMO A busca de novas alternativas para reutilizar resíduos é uma maneira de minimizar impactos ambientais promovendo práticas sustentáveis. Este trabalho analisou a viabilidade técnica da produção de briquetes a partir de resíduos de poda urbana e bagaço de cana-de-açúcar, transformando-os em um produto com maior valor agregado, além de direcionar seu uso e reduzir a disposição inadequada. Foram estudados cinco tratamentos a partir de diferentes proporções dos dois resíduos: sendo T1, T2, T3, T4 e T5, respectivamente, 100% de resíduo de poda urbana; 50% de resíduo de poda urbana e 50% de bagaço de cana; 24% de resíduo de poda urbana e 75% de bagaço de cana; 10% de resíduo de poda urbana e 90% de bagaço de cana; e 100% de bagaço de cana. Os materiais foram caracterizados física, química e energeticamente. Foram produzidos briquetes e avaliados quanto ao desempenho mecânico, com testes de expansão, resistência mecânica e friabilidade para verificar a qualidade do produto final. Os tratamentos 1 e 2 apresentaram os melhores resultados, com menor friabilidade e valor médio de resistência mecânica de 167,14 e 107,56 kgf, respectivamente. Conclui-se que ambos os resíduos (bagaço de cana e poda urbana) apresentaram potencial para produção de briquete, bem como a mistura entre os dois materiais.
ABSTRACT The search for new alternatives in order to reuse residues is one way to minimize environmental impacts by promoting sustainable practices. This study analyzed the technical feasibility of briquettes production from urban pruning residue and sugarcane bagasse, turning them into a product with higher added value besides directing their use and reducing their improper disposal. Five treatments were studied from different ratios of the two residues: T1, T2, T3, T4 and T5, respectively made of 100% of urban pruning; 50% urban pruning and 50% sugarcane bagasse; 25% urban pruning and 75% sugarcane bagasse; 10% urban pruning and 90% sugarcane bagasse; 100% sugarcane bagasse. The materials were characterized physically, chemically and energetically. Briquettes were produced and evaluated for mechanical performance, with expansion tests, mechanical resistance and friability to verify the quality of the final product. The treatments 1 and 2 showed the best results, with lower friability and average values of mechanical resistance of 167.14 and 107.56 kgf, respectively. It is concluded that both residues (sugarcane bagasse and urban pruning) had potential for briquette production, as well as the mixture between both materials.

OBJECTIVES: To develop a version of the modified Japanese Orthopaedic Association (mJOA) scale that had been translated into Portuguese and cross-culturally adapted for the Brazilian population. METHODS: The well-established process of forward-backward translation was employed along with cross-cultural adaptation. RESULTS: Three bilingual translators (English and native Portuguese) performed the forward translation of the mJOA scale from English to Portuguese based on iterative discussions used to reach a consensus translation. The translated version of the mJOA scale was then back-translated into English by a native English-speaking translator unaware of the concepts involved with the mJOA scale. The original mJOA scale and the back-translated version were compared by a native North American neurosurgeon, and as they were considered equivalent, the final version of the mJOA scale that had been translated into Portuguese and cross-culturally adapted was defined. CONCLUSION: To facilitate global and cross-cultural comparisons of the severity of cervical myelopathy, this study presents a version of the mJOA scale that was translated into Portuguese and cross-culturally adapted for the Brazilian population.

Abstract: The woodwasp Sirex obesus Bradley is described from specimens fortuitously captured in Lindgren funnel traps used in studies on the flight of the bark beetle Dendroctonus mexicanus Hopkins and through the direct capture on the bark of trees, in the municipality of San José de Gracia, Aguacalientes, Mexico. Pinus leiophylla Schl.et. Cham. and Pinus teocote Schl. et. Cham., weakened by the presence of D. mexicanus, were identified as hosts of S. obesus. The adults of this species emerge and oviposit during October and November. As parasitoids of S. obesus, some specimens of Ibalia leucospoides Hochenwarth (Hymenoptera: Ibaliidae) were collected in the same pine sections where the specimens of S. obesus emerged. This is the first record of the species in the state of Aguascalientes; therefore, more attention should be given to this insect because of its potential risk of invading pine trees and stands in Mexico.
Resumen: La avispa de la madera Sirex obesus Bradley se describe a partir de especímenes capturados de manera fortuita, en trampas de embudos Lindgren utilizadas en estudios sobre el vuelo del descortezador Dendroctonus mexicanus Hopkins y mediante la captura directa sobre la corteza de árboles, en el municipio de San José de Gracia, Aguascalientes, México. Como hospederos de S. obesus se identificaron Pinus leiophylla Schl. et. Cham. y Pinus teocote Schl. et Cham., debilitados por la presencia de D. mexicanus. Los adultos de esta especie emergen y ovipositan durante octubre y noviembre. Como parasitoides de S. obesus se recolectaron algunos ejemplares de Ibalia leucospoides Hochenwarth (Hymenoptera: Ibaliidae) en las mismas trozas de pino de las que emergieron especímenes de S. obesus. Este es el primer registro de la especie en el estado de Aguascalientes, por lo cual más atención debe darse a este insecto debido al riesgo potencial que tiene para invadir árboles y rodales de pino en México.

Abstract Introduction: Antiplatelet therapy after coronary artery bypass graft (CABG) has been used. Little is known about the predictors and efficacy of clopidogrel in this scenario. Objective: Identify predictors of clopidogrel following CABG. Methods: We evaluated 5404 patients who underwent CABG between 2000 and 2009 at Duke University Medical Center. We excluded patients undergoing concomitant valve surgery, those who had postoperative bleeding or death before discharge. Postoperative clopidogrel was left to the discretion of the attending physician. Adjusted risk for 1-year mortality was compared between patients receiving and not receiving clopidogrel during hospitalization after undergoing CABG. Results: At hospital discharge, 931 (17.2%) patients were receiving clopidogrel. Comparing patients not receiving clopidogrel at discharge, users had more comorbidities, including hyperlipidemia, hypertension, heart failure, peripheral arterial disease and cerebrovascular disease. Patients who received aspirin during hospitalization were less likely to receive clopidogrel at discharge (P≤0.0001). Clopidogrel was associated with similar 1-year mortality compared with those who did not use clopidogrel (4.4% vs. 4.5%, P=0.72). There was, however, an interaction between the use of cardiopulmonary bypass and clopidogrel, with lower 1-year mortality in patients undergoing off-pump CABG who received clopidogrel, but not those undergoing conventional CABG (2.6% vs 5.6%, P Interaction = 0.032). Conclusion: Clopidogrel was used in nearly one-fifth of patients after CABG. Its use was not associated with lower mortality after 1 year in general, but lower mortality rate in those undergoing off-pump CABG. Randomized clinical trials are needed to determine the benefit of routine use of clopidogrel in CABG.

<sec><title>INTRODUCTION:</title><p> Recent studies at sites in northern Australia have reported severe and rapid decline of several native mammal species, notwithstanding an environmental context (small human population size, limited habitat loss, substantial reservation extent) that should provide relative conservation security. All of the more speciose taxonomic groups of mammals in northern Australia have some species for which their conservation status has been assessed as threatened, with 53 % of dasyurid, 47 % of macropod and potoroid, 33 % of bandicoot and bilby, 33 % of possum, 30 % of rodent, and 24 % of bat species being assessed as extinct, threatened or near threatened. However, the geographical extent and timing of declines, and their causes, remain poorly resolved, limiting the application of remedial management actions.</p></sec><sec><title>MATERIAL AND METHODS:</title><p> Focusing on the tropical savannas of northern Australia, this paper reviews disparate recent and ongoing studies that provide information on population trends across a broader geographic scope than the previously reported sites, and examines the conservation status and trends for mammal groups (bats, macropods) not well sampled in previous monitoring studies. It describes some diverse approaches of studies seeking to document conservation status and trends, and of the factors that may be contributing to observed patterns of decline.</p></sec><sec><title>RESULTS AND DISCUSSION:</title><p><italic>Current trends and potential causal factors for declines</italic>. The studies reported demonstrate that the extent and timing of impacts and threats have been variable across the region, although there is a general gradational pattern of earlier and more severe decline from inland lower rainfall areas to higher rainfall coastal regions. Some small isolated areas appear to have retained their mammal species, as have many islands which remain critical refuges. There is now some compelling evidence that predation by feral cats is implicated in the observed decline, with those impacts likely to be exacerbated by prevailing fire regimes (frequent, extensive and intense fire), by reduction in ground vegetation cover due to livestock and, in some areas, by 'control' of dingoes. However the impacts of dingoes may be complex, and are not yet well resolved in this area. The relative impacts of these individual factors vary spatially (with most severe impacts in higher rainfall and more rugged areas) and between different mammal species, with some species responding idiosyncratically: the most notable example is the rapid decline of the northern quoll (<italic>Dasyurus hallucatus</italic>) due to poisoning by the introduced cane toad (<italic>Rhinella marina</italic>), which continues to spread extensively across northern Australia. The impact of disease, if any, remains unresolved.</p></sec><sec><title>CONSERVATION MANAGEMENT RESPONSES:</title><p> Recovery of the native mammal fauna may be impossible in some areas. However, there are now examples of rapid recovery following threat management. Priority conservation actions include: enhanced biosecurity for important islands, establishment of a network of feral predator exclosures, intensive fire management (aimed at increasing the extent of longer-unburnt habitat and in delivering fine scale patch burning), reduction in feral stock in conservation reserves, and acquisition for conservation purposes of some pastoral lands in areas that are significant for mammal conservation.</p></sec>
<sec><title>INTRODUCCIÓN:</title><p> En estudios recientes en sitios al norte de Australia se ha informado una rápida y severa disminución de algunas especies de mamíferos nativos, a pesar de un contexto ambiental favorable (de baja población humana, pérdida de hábitat limitado, de un grado sustancial reservas) que debe proporcionar una seguridad relativa de conservación. Todos los grupos taxonómicos con mayor riqueza de especies de mamíferos en el norte de Australia tienen algunas especies cuyo estado de conservaciÓn se ha evaluado como amenazadas, con un 53 % de dasyuridae, el 47 % de macropodae y potoroidae, el 33% de bandicoot y bilby, el 33 % zarigÍ1/4eyas, el 30 % de los roedores, y el 24 % de las especies de murciélagos están evaluados como extintas, amenazadas o casi amenazadas. Sin embargo, el alcance geográfico y cronológico de las disminuciones, y sus causas, siguen estando mal resueltos, lo que limita la aplicación de medidas de gestión de recuperación.</p></sec><sec><title>MATERIAL Y MÉTODOS:</title><p> Centrándose en las sabanas tropicales del norte de Australia, en este trabajo se revisan los estudios recientes y se proporciona información sobre las tendencias de población a través de un Ámbito geográfico más amplio y se proporciona información sobre el estado de conservación y las tendencias de mamífero grupos (murciélagos, macropodos) no así la muestra en los estudios de seguimiento anteriores. Se describen algunos enfoques diversos de los estudios que documentan sobre el estado de conservación, las tendencias, y de los factores que pueden estar contribuyendo a los patrones observados de declive.</p></sec><sec><title>RESULTADOS Y DISCUSIÓN:</title><p> Las tendencias actuales y los posibles factores causales de caídas. Los estudios publicados demuestran que la magnitud y oportunidad de los impactos y amenazas han sido variables en toda la región, a pesar de que existe un patrón gradual general de descenso que antes, y más grave de zonas de precipitaciones inferiores a las regiones costeras de mayor precipitación. Algunas pequeñas zonas aisladas parecen haber conservado sus especies de mamíferos, al igual que muchas islas en las que permanecen refugios críticos. En la actualidad existe cierta evidencia convincente de que la depredación por gatos salvajes está implicada en la disminución observada, con estos impactos podrían verse agravados por los regímenes de fuego (fuego frecuente, extensa e intensa), que prevalece por la reducción de la cobertura vegetal del suelo debido a la ganadería y, en algunas Áreas, por "control" de los dingos. Sin embargo, los impactos de los dingos pueden ser complejos, y sin embargo, no están bien resueltas en esta Área. Los impactos relativos de estos factores individuales varían espacialmente (con la mayoría de los impactos severos en Áreas de mayor precipitación y Áreas escarpadas) y entre las diferentes especies de mamíferos, no obstante con algunas especies de responder idiosincrásicamente: el ejemplo más notable es la rápida disminución del quoll del norte (<italic>Dasyurus hallucatus</italic>) debido a la intoxicación por el sapo de caña introducido (<italic>Rhinella marina</italic>), que continúa propagándose ampliamente en todo el norte de Australia. El impacto de la enfermedad, en su caso, sigue sin resolverse.</p></sec><sec><title>RESPUESTAS DE LA ADMINISTRACIÓN DE CONSERVACIÓN.</title><p> La recuperación de la fauna de mamíferos nativos puede ser imposible en algunas Áreas. Sin embargo, ahora hay ejemplos de una rápida recuperación siguiente a la gestión de amenazas. Acciones prioritarias de conservación incluyen: una mayor bioseguridad para las islas importantes, establecimiento de una red de exclusiones de depredadores salvajes, manejo de incendios intensivos (dirigido a aumentar la extensión del hábitat más extenso sin quemar y en el suministro de una escala fina del parche de quema), reducción de acciones salvajes en las reservas de conservación y adquisición con de algunas tierras de pastoreo en Áreas que son importantes para la conservación de los mamíferos.</p></sec>

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

INTRODUCTION: Chronic kidney disease is a serious health problem in El Salvador. Since the 1990s, there has been an increase in cases unassociated with traditional risk factors. It is the second leading cause of death in men aged >18 years. In 2009, it was the first cause of in-hospital death for men and the fifth for women. The disease has not been thoroughly studied. OBJECTIVE: Characterize clinical manifestations (including extrarenal) and pathophysiology of chronic kidney disease of nontraditional causes in Salvadoran farming communities. METHODS: A descriptive clinical study was carried out in 46 participants (36 men, 10 women), identified through chronic kidney disease population screening of 5018 persons. Inclusion criteria were age 18 - 59 years; chronic kidney disease at stages 2, 3a and 3b, or at 3a and 3b with diabetes or hypertension and without proteinuria; normal fundoscopic exam; no structural abnormalities on renal ultrasound; and HIV-negative. Examinations included social determinants; psychological assessment; clinical exam of organs and systems; hematological and biochemical parameters in blood and urine; urine sediment analysis; markers of renal damage; glomerular and tubular function; and liver, pancreas and lung functions. Renal, prostate and gynecological ultrasound; and Doppler echocardiography and peripheral vascular and renal Doppler ultrasound were performed. RESULTS: Patient distribution by chronic kidney disease stages: 2 (32.6%), 3a (23.9%), 3b (43.5%). Poverty was the leading social determinant observed. Risk factor prevalence: agrochemical exposure (95.7%), agricultural work (78.3%), male sex (78.3%), profuse sweating during work (76.3%), malaria (43.5%), NSAID use (41.3%), hypertension (36.9%), diabetes (4.3%). General symptoms: arthralgia (54.3%), asthenia (52.2%), cramps (45.7%), fainting (30.4). Renal symptoms: nycturia (65.2%), dysuria (39.1%), foamy urine (63%). Markers of renal damage: macroalbuminuria (80.4%), β2 microglobulin (78.2%), NGAL (26.1%). Renal function: hypermagnesuria (100%), hyperphosphaturia (50%), hypernatriuria (45.7%), hyperkaluria (23.9%), hypercalciuria (17.4%), electrolyte polyuria (43.5%), metabolic alkalosis (45.7%), hyponatremia (47.8%), hypocalcemia (39.1%), hypokalemia (30.4%), hypomagnesemia (19.6%). Imaging: Ultrasound showed fatty liver (93.5%) and vascular Doppler showed tibial artery damage (66.7%). Neurological symptoms: abnormal tendon reflexes (45.6%), Babinski sign and myoclonus (6.5%), sensorineural hearing loss (56.5%). CONCLUSIONS: This chronic kidney disease studied behaves clinically like chronic tubulointerstitial nephropathy, but with systemic manifestations not attributable to kidney disease. While male agricultural workers predominated, women and adolescents were also affected. Findings support a hypothesis of multifactorial etiology with a key role played by nephrotoxic environmental agents.

South Africa has a long track record in Southern Ocean and Antarctic research and has recently invested considerable funds in acquiring new infrastructure for ongoing support of this research. This infrastructure includes a new base at Marion Island and a purpose-built ice capable research vessel, which greatly expand research opportunities. Despite this investment, South Africa's standing as a participant in this critical field is threatened by confusion, lack of funding, lack of consultation and lack of transparency. The research endeavour is presently bedevilled by political manoeuvring among groups with divergent interests that too often have little to do with science, while past and present contributors of research are excluded from discussions that aim to formulate research strategy. This state of affairs is detrimental to the country's aims of developing a leadership role in climate change and Antarctic research and squanders both financial and human capital.

OBJECTIVE: To explore social determinants of drinking water beliefs and practices among the Tz'utujil Maya of Santiago Atitlán, Guatemala, through analysis of demographics, socioeconomic status, memory of historical events, sensory experience, and water attitudes. METHODS: Parallel mixed (qualitative and quantitative) methods, including participant observation, in-depth interviews based on a purposive sample, and 201 semi-structured interviews based on a regional quota sample, were used to collect data from March 2007 to August 2008. Data analysis included the use of grounded theory methodology and Pearson's chi-square test for independence. RESULTS: Qualitative results based on grounded theory highlighted how memory of the Guatemalan Civil War and Hurricane Stan, attitudes about Lake Atitlán water, and the taste and smell of chlorine influenced Tz'utujil Maya drinking water beliefs. Quantitative survey results revealed that differences in ethnicity, literacy, years of schooling, distrust of the water supply during the Civil War and Hurricane Stan, and current beliefs about Lake Atitlán and tap water quality were associated with significantly different water self-treatment practices. CONCLUSIONS: In accordance with social determinants of health paradigms, demographic, socioeconomic, social, cultural, political, and historical factors continue to be significant determinants of water-related health. Public health water interventions must address inequalities related to these underlying factors in order to achieve maximum effectiveness.
OBJETIVO: Explorar los factores sociales determinantes de las creencias y prácticas con respecto al agua potable de la población maya tz'utujil, que habita en Santiago Atitlán (Guatemala), mediante el análisis de la información demográfica, la situación socioeconómica, la memoria de hechos históricos, la experiencia sensorial y las actitudes con respecto al agua. MÉTODOS: De marzo del 2007 a agosto del 2008, se recopilaron datos por medio de métodos paralelos mixtos (tanto cualitativos como cuantitativos), como la observación de participantes, entrevistas en profundidad basadas en un muestreo intencionado y 201 entrevistas semiestructuradas basadas en un muestreo por cuota regional. En el análisis de los datos se usó el método de la teoría fundamentada o muestreo teórico y la prueba de la chi al cuadrado de Pearson para la independencia. RESULTADOS: Los resultados cualitativos basados en la teoría fundamentada pusieron de relieve que los recuerdos de la guerra civil guatemalteca y del huracán Stan, las actitudes acerca del agua del Lago Atitlán, y el gusto y el olor del cloro influían las creencias de los tz'utujiles con respecto al agua potable. Los resultados cuantitativos de la encuesta indicaron que las diferencias a raíz del grupo étnico, el alfabetismo, los años de escolaridad, la desconfianza del abastecimiento de agua durante la guerra civil y el huracán Stan, y las creencias actuales acerca de la calidad del agua del Lago Atitlán y del agua de grifo estaban asociadas con prácticas de autotratamiento del agua sumamente diferentes. CONCLUSIONES: En consonancia con el paradigma de los factores sociales determinantes de la salud, los factores demográficos, socioeconómicos, sociales, culturales, políticos e históricos siguen siendo determinantes significativos de la salud en relación con el agua. Para que puedan lograr la mayor eficacia posible, las intervenciones de salud pública con respecto al agua deben abordar las desigualdades relacionadas con estos factores fundamentales.

The shelf off the Thukela River has a unique geological and oceanographic setting within the KwaZulu-Natal continental margin. High terrestrial sediment input from the Thukela is delivered to this unusually wide shelf, resulting in deposits that exhibit both deltaic and submarine fan characteristics, the latter initiated during flood events. The Inner shelf (0 to -30 m) is dominated by well-sorted sands reworked by fair-weather processes. The Mid-shelf (-30 to -60 m) comprises poorly sorted sands subjected to ocean storm processes and redistribution by the semi-permanent KwaZulu-Natal Gyre. The Outer shelf (-60 to -100 m) is characterized by gravels and large bedforms produced by the southerly-flowing Agulhas Current. During fair-weather conditions, the Mid-shelf is dominated by the KwaZulu-Natal Gyre and the Outer shelf by the Agulhas Current. During extreme flood events, sedimentation extends further offshore, building the submarine fan, overprinting the typical outer-shelf sediment distribution. This model provides a basis for the effective assessment and management of the biological communities and commercial prawn industry in the area.

Differential studies of elliptic flow are one of the most powerful tools in studying the initial conditions and dynamical evolution of heavy ion collisions. The comparison of data from Cu+Cu and Au+Au collisions taken with the PHOBOS experiment at RHIC provides new information on the interplay between initial geometry and initial particle density in determining the observed final state flow pattern. Studies from PHOBOS point to the importance of fluctuations in the initial state geometry for understanding the Cu+Cu data. We relate the elliptic flow data to the results of our model studies on initial state geometry fluctuations and discuss how we will perform measurements of event-by-event fluctuations in elliptic flow in Au+Au collisions.

AfrOBIS is one of 11 global nodes of the Ocean Biogeographic Information System (OBIS), a freely accessible network of databases collating marine data in support of the Census of Marine Life. Versatile graphic products, provided by OBIS, can be used to display the data. To date, AfrOBIS has loaded about 3.2 million records of more than 23 000 species located mainly in the seas around southern Africa. This forms part of the 13.2 million records of more than 80 000 species currently stored in OBIS. Scouting for South African data has been successful, whereas locating records in other African countries has been much less so.

PHOBOS is one of the four heavy ion experiments currently running at the Relativistic Heavy Ion Collider (RHIC). In this paper we will present some of the current results from PHOBOS: the study of charged multiplicity distribution as function of pseudorapidity and centrality at <IMG SRC="/img/revistas/bjp/v34n3a/a32img01.gif" > or = 19.6, 130 and 200 GeV, a discussion of multiplicity scaling, and a measurement of transverse momentum spectra (pT) of charged hadrons produced in d+Au and Au+Au interactions at <IMG SRC="/img/revistas/bjp/v34n3a/a32img01.gif" > or = 200 GeV. The dependence of the Au+Au yields as function of centrality is found to be independent of pT. A strong suppression in the Au+Au hadron spectra relative to p<IMG SRC="/img/revistas/bjp/v34n3a/a32img05.gif"> at high pT is observed. The spectral shape for d+Au collisions is significantly different from the observations in Au+Au, the yield suppression is not observed in d+Au.
