Persistent organic pollutants are a concern for species occupying high trophic levels since they can cause immunosuppression and impair reproduction. Mass mortalities due to canine distemper virus (CDV) occurred in Caspian seals (Pusa caspica), in spring of 1997, 2000 and 2001, but the potential role ...
Background The gametogenic cycle of Crassostrea gigas, a species imported into the Mediterranean for aquaculture, has been studied (May 2005 to July 2006) in two contrasting habitats of Tunisia: the Bizert lagoon, where oyster farms have been developed since 1970, and the Gulf of Tunis, where oysters ...
Historical research is playing an increasingly important role in marine sciences. Historical data are also used in policy making and marine resource management, and have helped to address the issue of shifting baselines for numerous species and ecosystems. Although many important research questions ...
The cortisol stress response and the molecular programming of the corticoid axis were characterized for the first time during early ontogeny in a Mediterranean marine teleost, the European sea bass (Dicentrarchus labrax). Sea bass embryos, pre-larvae and larvae at specific points of development were ...
Diving has become a prevalent way of performing research in underwater environments. One of the major concerns with diving is the health issues faced by the divers during deep sea dives which call for the necessity of a reliable health monitoring system. The paper mainly focuses on the architectural ...
Marine hydrokinetic (MHK) technologies attempt to recover the abundant energy source in the world's oceans and the advancement of these technologies forms the core of the activities of the Northwest National Marine Renewable Energy Center (NNMREC - a Department of Energy sponsored partnership between ...
A multidisciplinary senior project team consisting of five students from Design Engineering Technology (DET) and Manufacturing Engineering Technology (MFET) have been tasked to design and fabricate an indoor growing system using the VEGILAB technique and Aquaponics system. The project involves a collaborative ...
Chilko Lake sockeye constitute one of the largest salmon stocks in the Pacific Northwest, for which Fisheries and Oceans Canada has maintained a 55-year record, including partitioned freshwater and marine survival. The lake was also the site of fertilization experiments in the 1970s-1990s. This paper ...
In this paper, an algorithm is proposed to automatically produce hierarchical graph-based representations of maritime shipping lanes extrapolated from historical vessel positioning data. Each shipping lane is generated based on the detection of the vessel behavioural changes and represented in a compact ...
Food manufacturers are interested in developing emulsion-based products into nutritional foods by using beneficial oils, such as fish oil and virgin coconut oil (VCO). In this study, the physicochemical properties of a VCO oil-in-water emulsion was investigated and compared to other commercial oil-in-water ...
Complete segregation of the main olfactory epithelium (MOE) and the vomeronasal epithelium is first observed in amphibians. In contrast, teleost fishes possess a single olfactory surface, in which genetic components of the main and vomeronasal olfactory systems are intermingled. The transient receptor ...
Klinefelter syndrome (KS) is the most common sex chromosomal disorder in men. Most of these patients show the 47,XXY karyotype, whereas approximately 15% of them are mosaics with variable phenotype. A 39-year-old male investigated for primary infertility, was clinically normal with small firm testes ...
Anesthetics are drugs that reversibly relieve pain, decrease body movements and suppress neuronal activity. Most drugs only cover one of these effects; for instance, analgesics relieve pain but fail to block primary fiber responses to noxious stimuli. Alternately, paralytic drugs block synaptic transmission ...
Control of the extracellular environment of inner ear hair cells by ionic transporters is crucial for hair cell function. In addition to inner ear hair cells, aquatic vertebrates have hair cells on the surface of their body in the lateral line system. The ionic environment of these cells also appears ...
Regenerative medicine has the promise to alleviate morbidity and mortality caused by organ dysfunction, longstanding injury and trauma. Although regenerative approaches for a few diseases have been highly successful, some organs either do not regenerate well or have no current treatment approach to ...
Leonard Zon, who is based at Harvard Medical School, is internationally recognized for his pioneering work in hematology and stem cell biology. His lab uses zebrafish as a model to understand blood cell development and, in recent years, has made inspiring breakthroughs in the treatment of blood diseases ...
The Pasquotank River Watershed is found in Northeast North Carolina beginning in the Great Dismal Swamp at the Virginia/North Carolina border and flows into the Albemarle Sound. The watershed provides a transition between spawning grounds and the waters of the Albemarle Sound. The sound serves as a ...
Many governments are facing lack of resources and expecting some forms of Public Private Partnership (PPP) in service provision and infrastructure development. Meanwhile, many public entities have put solving social challenges as a priority in their science and innovation policies. However, both public ...
Hydropower, with characteristics of superior storage capacity and speedy response, can meet sudden fluctuations electricity demand. And its generation capacity could be doubled by 2050 according to IEA's recent estimation. Besides, hydropower doesn't require innovative technologies, and can be operated ...
In nature, a phase transition is the transformation of a thermodynamic system from one phase to another. Different phases of a thermodynamic system have distinctive physical properties. Inspired by this natural phenomenon, this paper presents a Particle Swarm Optimization (PSO) based on the Phase Transitions ...
