Abstract Offshore Arctic development presents unique challenges. Typical oil and gas pipeline designs used in other regions of the world can bring with them unforeseen consequences in the arctic. Such is the case of pipeline thermal insulation. Thermal insulation, in the form of an external foam coating ...
Abstract As the industry moves further offshore in the Arctic where open water seasons are small to non-existent, ice management will be a critical enabling technology to allow floating vessels to keep station (for drilling, tanker loading, well workovers or subsea equipment maintenance). This paper ...
Abstract Every human activity in the offshore Arctic, or anywhere offshore for that matter, emits some level of sound into the marine environment. Depending on intensity, and to some extent frequency, underwater sound can be a nuisance or even physically harmful to marine life. The indigenous people ...
Background Evidence suggests possible synergetic effects of multiple lifestyle behaviors on health risks like obesity and other health outcomes. Therefore it is important to investigate associations between dietary and physical activity behavior, the two most important lifestyle behaviors influencing ...
The marine bacterium Vibrio tapetis is the causative agent of the brown ring disease, which affects the clam Ruditapes philippinarum and causes heavy economic losses in North of Europe and in Eastern Asia. Further characterization of V. tapetis isolates showed that all the investigated strains harbored ...
Background The guppy (Poecilia reticulata) is an important model organism for studying sexual selection; male guppies have complex and conspicuous pigmentation, and female guppies exhibit preferences for males with specific color spots. Understanding the genetic basis underlying pigmentation variation ...
The biodiversity of the megabenthic assemblages of the mesophotic zone of a Tyrrhenian seamount (Vercelli Seamount) is described using Remotely Operated Vehicle (ROV) video imaging from 100 m depth to the top of the mount around 61 m depth. This pinnacle hosts a rich coralligenous community characterized ...
Infectious pancreatic necrosis virus (IPNV) can induce Bad-mediated apoptosis followed by secondary necrosis in fish cells, but it is not known how these two types of cell death are regulated by IPNV. We found that IPNV infection can regulate Bad/Bid-mediated apoptotic and Rip1/ROS-mediated necrotic ...
The progression of viral infections is notoriously difficult to follow in whole organisms. The small, transparent zebrafish larva constitutes a valuable system to study how pathogens spread. We describe here the course of infection of zebrafish early larvae with a heat-adapted variant of the Infectious ...
Background The farnesoid X receptor (FXR), pregnane X receptor (PXR), and vitamin D receptor (VDR) are three closely related nuclear hormone receptors in the NR1H and 1I subfamilies that share the property of being activated by bile salts. Bile salts vary significantly in structure across vertebrate ...
Pelagic ecosystems support a significant and vital component of the ocean's productivity and biodiversity. They are also heavily exploited and, as a result, are the focus of numerous spatial planning initiatives. Over the past decade, there has been increasing enthusiasm for protected areas as a tool ...
Chitin and chitosan production has been reported to be an economical technique to utilize the shrimp waste. Amajor fraction of the shrimp waste is tissue protein and seldom research investigated to recover the protein fraction through hydrolysis by using protease. This paper described the hydrolysis ...
While informationization is now the main direction and objective of agricultural development£¬digital agriculture is the key technique to realize the agro-informationization and an important means to solve the present problems of¡°agriculture£¬farmer and rural area¡±. In this paper, the development ...
The acceleration of urbanization is making the problem of environment pollution and the resources deficient more and more serious, while the drought and water shortage, flood disaster, etc., baffle the urbanization in turn. By summing-up the status of the utilization of urban rain-flood, the main problems ...
Shrimp wastewater was studied by using photosynthetic bacteria sludge method. The results indicated that this method got better effects than single sludge or only photosynthetic bacteria treatment. The removal of the CODcr could reach 63%, the removal of the NH3-N could reach 92.5£¥. Compared with conventional ...
Background Myostatin (MSTN) is a member of the transforming growth factor-ß superfamily that functions as a negative regulator of skeletal muscle development and growth in mammals. Fish express at least two genes for MSTN: MSTN-1 and MSTN-2. To date, MSTN-2 promoters have been cloned only from salmonids ...
Translocations of Baltic whitefish (Coregonus sp.) into Austrian Alpine lakes have created ‘artificial hybrid zones’, threatening the genetic integrity of native lineages. We evaluate the genetic structure of Coregonus in Austrian lakes and characterize hybridization and introgression between native ...
Antibiotic resistance is a major concern, yet it is unclear what causes the relatively high densities of resistant bacteria in the anthropogenically impacted environment. There are various possible scenarios (hypotheses): (A) Input of resistant bacteria from wastewater and agricultural sources is significant, ...
The structure and stability of parasite communities have been mainly explained by high diversity and strong interactions among parasite species. During 16 months, 558 Barbus martorelli gill infracommunities were studied in a tropical zone to determine whether parasite infrapopulations interact. Three ...
