Development of a system for 3D high-resolution seismic reflection profiling on lakes

A high-resolution three-dimensional (3D) seismic reflection system for small-scale targets in lacustrine settings has been developed. Its main characteristics include navigation and shot-triggering software that fires the seismic source at regular distance intervals (max. error of 0.25 m) with real-time control on navigation using differential GPS (Global Positioning System). Receiver positions are accurately calculated (error < 0.20 m) with the aid of GPS antennas attached to the end of each of three 24-channel streamers. Two telescopic booms hold the streamers at a distance of 7.5 m from each other. With a receiver spacing of 2.5 m, the bin dimension is 1.25 m in inline and 3.75 m in crossline direction. To test the system, we conducted a 3D survey of about 1 km(2) in Lake Geneva, Switzerland, over a complex fault zone. A 5-m shot spacing resulted in a nominal fold of 6. A double-chamber bubble-cancelling 15/15 in(3) air gun (40-650 Hz) operated at 80 bars and 1 m depth gave a signal penetration of 300 m below water bottom and a best vertical resolution of 1.1 m. Processing followed a conventional scheme, but had to be adapted to the high sampling rates, and our unconventional navigation data needed conversion to industry standards. The high-quality data enabled us to construct maps of seismic horizons and fault surfaces in three dimensions. The system proves to be well adapted to investigate complex structures by providing non-aliased images of reflectors with dips up to 30 degrees.

FRAX(®) Clinical Task Force of the 2010 Joint International Society for Clinical Densitometry & International Osteoporosis Foundation Position Development Conference.

The World Health Organization fracture risk assessment tool, FRAX(®), is an advance in clinical care that can assist in clinical decision-making. However, with increasing clinical utilization, numerous questions have arisen regarding how to best estimate fracture risk in an individual patient. Recognizing the need to assist clinicians in optimal use of FRAX(®), the International Osteoporosis Foundation (IOF) in conjunction with the International Society for Clinical Densitometry (ISCD) assembled an international panel of experts that ultimately developed joint Official Positions of the ISCD and IOF advising clinicians regarding FRAX(®) usage. As part of the process, the charge of the FRAX(®) Clinical Task Force was to review and synthesize data surrounding a number of recognized clinical risk factors including rheumatoid arthritis, smoking, alcohol, prior fracture, falls, bone turnover markers and glucocorticoid use. This synthesis was presented to the expert panel and constitutes the data on which the subsequent Official Positions are predicated. A summary of the Clinical Task Force composition and charge is presented here.

Compressibilidade de três Latossolos em função da umidade e uso

Por meio do ensaio de compressibilidade, foram estudados os efeitos do manejo e da umidade na pressão de preconsolidação (σp) de três solos: Latossolo Vermelho-Amarelo, Latossolo Roxo e Latossolo Vermelho-Escuro sob cultura anual, mata natural e pastagem, na região de Lavras (MG), em duas profundidades (0-0,03 e 0,27-0,30 m). Para cada condição, foram coletadas cinco amostras indeformadas e uma deformada, com três repetições. As amostras, indeformadas e com diferentes umidades, foram utilizadas no ensaio de compressão uniaxial, obtendo-se as curvas de compressão, das quais foram extraídas as respectivas pressões de preconsolidação. Com as amostras deformadas, determinaram-se os limites de plasticidade e de contração, textura e matéria orgânica. Os modelos de compactação testados foram baseados na pressão de preconsolidação e na umidade do solo. Para uma mesma condição e profundidade, houve diferença significativa entre os valores dos teores de argila e areia nos três solos. Os valores da densidade do solo inicial (Ds i) foram estatisticamente diferentes para todas as condições na mesma profundidade, exceto na camada de 0-0,03 m para a cultura anual. À medida que a umidade do solo aumentou, a pressão de preconsolidação decresceu exponencialmente, indicando uma redução na capacidade de suporte de carga do solo. O LR apresentou, em geral, maior capacidade de suporte de carga do que o LE e LV. Essa maior capacidade de suporte de carga pode estar associada com o seu maior teor de argila e menor teor de areia. A capacidade de suporte de carga na zona de friabilidade variou de 154 a 167 kPa, para o LV; de 77 a 183 kPa, para o LR, e de 77 a 132 kPa, para o LE. As umidades 0,33 a 0,30 kg kg-1, 0,42 a 0,27 kg kg-1, e 0,35 a 0,33 kg kg-1 correspondem à faixa de friabilidade (LP - LC) do LV, LR e LE, respectivamente. O modelo baseado na história de tensão do solo evidenciou o efeito da compactação causada pelas máquinas de preparo do solo na camada de 0,27-0,30 m, para a cultura anual, enquanto, para a pastagem, ocorreu o efeito do pisoteio do gado na camada de 0-0,03 m.

Informing the judgments of fingerprint analysts using quality metric and statistical assessment tools

The aim of this research was to evaluate how fingerprint analysts would incorporate information from newly developed tools into their decision making processes. Specifically, we assessed effects using the following: (1) a quality tool to aid in the assessment of the clarity of the friction ridge details, (2) a statistical tool to provide likelihood ratios representing the strength of the corresponding features between compared fingerprints, and (3) consensus information from a group of trained fingerprint experts. The measured variables for the effect on examiner performance were the accuracy and reproducibility of the conclusions against the ground truth (including the impact on error rates) and the analyst accuracy and variation for feature selection and comparison.¦The results showed that participants using the consensus information from other fingerprint experts demonstrated more consistency and accuracy in minutiae selection. They also demonstrated higher accuracy, sensitivity, and specificity in the decisions reported. The quality tool also affected minutiae selection (which, in turn, had limited influence on the reported decisions); the statistical tool did not appear to influence the reported decisions.

Caracterización de redes de cerco artesanal para anchoveta destinada al consumo humano directo

Las características principales de las redes de cerco artesanales anchoveteras para CHD (PS 01.1.0 “ISSCFG”), utilizan tamaños de malla en el copo y cuerpo de ½” ~ 13 mm de material nylon Poliamida (PA). Se encontró una diferencia en las dimensiones, el material y diámetro del hilo del paño usado, entre las redes de las ANC-CHD tradicionales (Paita, Chimbote, Callao e Ilo) que utilizan paños anchoveteros de R310tex, R381tex R462tex, con longitud de relinga superior (LRS) de 183-366 m (100 a 200 bz), altura de paño estirado (AHE) de 27 a 64 m (15 a 35 bz); y las redes de cerco ANC-Pisco que utilizan paños anchoveteros de R155tex y R230tex, con LRS de 270 a 396 m (145 a 215 bz) y AHE de 30 m (16 bz). Del análisis regresional experimental, las principales características de la red (LRS, AHE), y la embarcación–capacidad de bodega-(CBOD) presentaron correlaciones significativas para la flota ANC-Tradicional (r = 0,86 y 0,91), mientras que en la flota ANC-Pisco las correlación de la función CBODLRS fue de 0,30 y la AHE fue constante (30 m) para todo el rango de LRS (270 - 396 m).

Coexistence of specialist and generalist species is shaped by dispersal and environmental factors.

Disentangling the mechanisms mediating the coexistence of habitat specialists and generalists has been a long-standing subject of investigation. However, the roles of species traits and environmental and spatial factors have not been assessed in a unifying theoretical framework. Theory suggests that specialist species are more competitive in natural communities. However, empirical work has shown that specialist species are declining worldwide due to habitat loss and fragmentation. We addressed the question of the coexistence of specialist and generalist species with a spatially explicit metacommunity model in continuous and heterogeneous environments. We characterized how species' dispersal abilities, the number of interacting species, environmental spatial autocorrelation, and disturbance impact community composition. Our results demonstrated that species' dispersal ability and the number of interacting species had a drastic influence on the composition of metacommunities. More specialized species coexisted when species had large dispersal abilities and when the number of interacting species was high. Disturbance selected against highly specialized species, whereas environmental spatial autocorrelation had a marginal impact. Interestingly, species richness and niche breadth were mainly positively correlated at the community scale but were negatively correlated at the metacommunity scale. Numerous diversely specialized species can thus coexist, but both species' intrinsic traits and environmental factors interact to shape the specialization signatures of communities at both the local and global scales.
