Boujagh National Park, with water ecosystems including Boujagh and Kiashahr wetlands, has an area of approximately 3477.3 hectares. In order to study factors affecting the vegetation in aquatic and wet habitats, 44 releves were implemented in the region. To test the chemical properties of the available water, samples were collected from 22 releves. The results of a two-way species indicator analysis of the modified TWINSPAN suggested that four groups of plants were present in the region. The fir...

Knowledge of the early evolution of sea turtles (Chelonioidea) has been limited by conflicting phylogenetic hypotheses resulting from sparse taxon sampling and a superficial understanding of the morphology of key taxa. This limits our understanding of evolutionary adaptation to marine life in turtles, and in amniotes more broadly. One problematic group are the protostegids, Early–Late Cretaceous marine turtles that have been hypothesised to be either stem-cryptodires, stem-chelonioids, or crown-...

The new Royal Portuguese Navy was born after the Lisbon earthquake, 1755. The Naval reform was intended in the XVII century, during the D. João IV reign. But, this reform didin`t broke out. Only the XVIII century could bring the Naval reform. In another places of the Portuguese Empire another situations broke up, as we bring in this article with the José Pires de Carvalho e Albuquerque attempt of became the Salvador Navy Yard commandant; even without conditions for this charge after the Marquês ...

This observational study reports that several globally distributed tide gauge stations exhibit a propensity of statistically significant sea level accelerations during the satellite altimetry era. However, the magnitudes of the estimated tide gauge accelerations during this period are systematically and noticeably smaller than the global mean sea level acceleration reported by recent analyses of satellite altimetry. The differences are likely to be caused by the interannual, decadal and interdec...

Abstract The North Equatorial Current (NEC) bifurcates at the eastern coast of the Philippines and moves northward as the Kuroshio, a North Pacific western boundary current. The NEC bifurcation point and Kuroshio variability are known to be affected by changes in climate such as the El Niño–Southern Oscillation and the pacific decadal oscillation. However, observational data are not sufficient to examine the mechanisms of decadal fluctuation. Here, we report seasonal radiocarbon data recorded fr...

Sea ice concentrations are determined from the visible and near infrared albedo of the AVHRR imagery. One method uses only one channel data to interpolate the ice concentration between 0 and 100% corresponding to the open water and the snow cover, respectively. This method yieds an uncertainty owing to the variation of albedo by the surface condition change. Another method uses two-channel data to derive not only the ice concentration but also the ice surface condition and can eliminate uncertai...

Abstract Coral reefs worldwide face an uncertain future with many reefs reported to transition from being dominated by corals to macroalgae. However, given the complexity and diversity of the ecosystem, research on how regimes vary spatially and temporally is needed. Reef regimes are most often characterised by their benthic components; however, complex dynamics are associated with losses and gains in both fish and benthic assemblages. To capture this complexity, we synthesised 3,345 surveys fro...

Abstract In this study, we look closer at how high fish densities influence wound repair mechanisms in post-smolt Atlantic salmon. The fish were wounded with a 5 mm skin punch biopsy needle and stocked at two different densities, a high fish density (100 kg/m3) treatment and a low fish density treatment (20 kg/m3) serving as the control. The healing wounds were followed for 57 days with samples taken 1, 3, 7, 14, 36, 43 and 57 days post wounding. The transcriptomic analysis suggests that high fi...

Abstract Direct measures of energy expenditure are difficult to obtain in marine mammals, and accelerometry may be a useful proxy. Recently its utility has been questioned as some analyses derived their measure of activity level by calculating the sum of accelerometry-based values and then comparing this summation to summed (total) energy expenditure (the so-called “time trap”). To test this hypothesis, we measured oxygen consumption of captive fur seals and sea lions wearing accelerometers duri...

Polarisation processes, which began in Croatia in the 1950's, resulted in disparate socio-economic development, in an uneven spatial distribution of the population, and in a concentration of people, jobs and housing in urban settlements. Coastal cities, as hubs and agents of socio-economic development, in their regions became focal points for the concentration of the population, while islands and hinterland areas suffered depopulation and demographic ageing. Intense in-migration had a positive i...

Summary: Studying hydrodynamic processes is necessary for understanding the sediment erosion–deposition mechanism in mangrove areas. The hydrodynamic effects within the mangrove area of the Dong Tranh Estuary in the Can Gio Mangrove Biosphere Reserve in Ho Chi Minh City (HCMC), Vietnam are very complicated and are caused by the mixed impacts of waves, tides, currents and suspended sediment concentrations (SSCs). In this study, the measurements of hydrodynamics such as waves, currents and SSCs we...

<p>Abstract</p> <p>Background</p> <p>Pleural effusions are classified into transudates and exudates. Various criteria have been used with Light's et al being the most accepted ones. Glycosaminoglycans (GAGs) have been detected during pleural fluids (PF) analysis in various causes. In this pilot study, we investigated: (a) the usefulness of GAGs in the assessment of pleural effusions, and (b) whether and in what way GAGs correlate with established criteria used to indicate an exudate.</p> <p>Meth...

<p>Abstract</p> <p>Background</p> <p>The importance of human rights education has widely been recognized as one of the strategies for their protection and promotion of health. Yet training programs have not always taken into account neither local needs, nor public health relevance, nor pedagogical efficacy.</p> <p>The objectives of our study were to assess, in a participative way, educational needs in the field of health and human rights among potential trainees in six French-speaking African co...

<p>Abstract</p> <p>Background</p> <p>The aquatic birnavirus infectious pancreatic necrosis virus (IPNV) causes infectious pancreatic necrosis (IPN), a severe disease in farmed salmonid fish. IPNV has a very broad host range and infects many different species of fish as well as molluscs and crustaceans. Investigation of the host reservoir of a virus may reveal important molecular mechanisms governing the infection processes such as receptors and entry mechanisms. In the present work we have studi...

<p>Abstract</p> <p>Background</p> <p>The salmon louse (<it>Lepeophtheirus salmonis </it>Krøyer), an ectoparasitic copepod with a complex life cycle causes significant losses in salmon aquaculture. Pesticide treatments against the parasite raise environmental concerns and their efficacy is gradually decreasing. Improvement of fish resistance to lice, through biological control methods, needs better understanding of the protective mechanisms. We used a 21 k oligonucleotide microarray and RT-qPCR t...

<p>Abstract</p> <p>Background</p> <p>Computational methods for identifying selenoproteins have been developed rapidly in recent years. However, it is still difficult to identify the open reading frame (ORF) of eukaryotic selenoprotein gene, because the TGA codon for a selenocysteine (Sec) residue in the active centre of selenoprotein is traditionally a terminal signal of protein translation. Although the identification of selenoproteins from genomes through bioinformatics methods has been conduc...

<p>Abstract</p> <p>Objective</p> <p>High tibial osteotomy (HTO) is one treatment option for young and active patients with unicompartmental osteoarthritis. The success of this procedure substantially depends on the degree of correction of the mechanical axis. Computer-assisted navigation systems are believed to improve the precision of axis correction through intraoperative real-time monitoring. This study investigates the accuracy of limb alignment measurements with a navigation system on a cad...

<p>Abstract</p> <p>Background</p> <p>Thoracotomy is associated with severe pain that may persist for years. Acupuncture is a complementary therapy with a proven role in pain control. A randomized trial showed that acupuncture was effective in controlling pain after abdominal surgery, but the efficacy of this technique for the treatment of thoracotomy pain has not been established. We developed a novel technique for convenient application of acupuncture to patients undergoing thoracotomy, and in ...
