Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are omega-3 (n-3) fatty acids (FAs) known to influence cardiometabolic markers of health. Evidence suggests that single nucleotide polymorphisms (SNPs) in the fatty acid desaturase 1 and 2 (FADS1/2) gene cluster may influence an individual’s ...
The induction of polyploidy is considered the reproductive end of cells, but there is evidence that polyploid giant cancer cells (PGCCs) contribute to cell repopulation during tumor relapse. However, the role of these cells in the development, progression and response to therapy in colon cancer remains ...
This work is a part of the Taiwan Cooperative Oceanic Fisheries Investigation, the first large scale hydrographic and plankton survey around Taiwan (21–26°N, 119–123°E). The present study examined the influence of hydrodynamic and biological variables driven by monsoon system on the siphonophore assemblages ...
Biotic indices, which reflect the quality of the environment, are widely used in the marine realm. Sometimes, key species or ecosystem engineers are selected for this purpose. This is the case of the Mediterranean seagrass Posidonia oceanica, widely used as a biological quality element in the context ...
White sharks are highly migratory and segregate by sex, age and size. Unlike marine mammals, they neither surface to breathe nor frequent haul-out sites, hindering generation of abundance data required to estimate population size. A recent tag-recapture study used photographic identifications of white ...
The context-dependent investigations of host–pathogen genotypic interactions, where environmental factors are explicitly incorporated, allow the assessment of both coevolutionary history and contemporary ecological influences. Such a functional explanatory framework is particularly valuable for describing ...
VMSbase is an R package devised to manage, process and visualize information about fishing vessels activity (provided by the vessel monitoring system - VMS) and catches/landings (as reported in the logbooks). VMSbase is primarily conceived to be user-friendly; to this end, a suite of state-of-the-art ...
Abstract Oil companies must be prepared to work in the Arctic environment and face among others challenges related to darkness, ice, remoteness, lack of infrastructure and vulnerable environments. This paper describes a new R&D programme, that eni e&p, in collaboration with Eni Norge, is developing ...
Abstract Results of research of anticorrosion Plasma Electrolytic Oxidation (PEO) coatings for marine equipment are presented. The influence of PEO layers and surface conditions on the intensity of corrosion processes using electrochemical impedance spectroscopy, differential thermal analysis and thermal ...
Abstract Fender has been used for the protection of ship hull from impact forces caused at the berthing to a quay, by its shock absorbing effects. It is also useful to avoid damages to the passengers and crew, and to protect the quay. In this study, the effects of cross sectional shape of a fender ...
Abstract In this paper, we analyzed the data of marine disasters in Chinese coastal areas in 24 years from 1989 to 2012. According to the analysis results, the uncertainty degree of marine disaster hazards increased and the exposure and vulnerability of coastal hazard bearing bodies also gradually ...
Abstract The forecast of processes development of ship's steel structures' defects accumulation over the operating time is one of the most difficult problems of reliability assessment of marine engineering. Particular difficulties related to the investigation of structural defects in the special gain, ...
Abstract A new technology, utilizing electromagnetic force to promote deformation of ship hull plate during line heating process, is called electromagnetic force assisted line heating (EFALH), which can improve efficiency and accuracy of plate deformation. Some key issues are solved in the numerical ...
Abstract A new method of parametric design combined with form parameter extraction method based on the geometric characteristics of parent ship has been presented in this paper. An improved fairing method which is based on the energy minimization and sum of squares of shearing force jerk is used to ...
Abstract A mathematically-defined family of ship hulls that consist of a forebody 0 ≤ × ≤ ℓ; and a cylindrical region -1+ ℓ ≤ × ≤ 0 aft of the forebody is considered. The cylindrical surface aft of the forebody has nearly rectangular framelines, with beam 2b and draft d: The forebody is determined ...
Abstract This study presents bathymetric changes and its characteristics due to high waves and fluvial floods are examined for wave-dominated delta-front of Tenryu river, a sediment-rich river on the Pacific coast (Enshu-nada) of central Japan. Frequent continuous bathymetries around the river mouth ...
Abstract Wave loads and slamming loads acting on the ship's hull lead to super-position of low-frequency wave-induced stresses and high-frequency stresses from whipping as well as springing effects. The question to which amount the latter contributes to the total fatigue damage of struc-tural details ...
Abstract As offshore pipeline installation in deepwater and arctic applications increases, technical requirements for pipe coating and flow assurance thermal insulation are progressing along the following trends: longer design life, longer tie-back, lower U value, deeper water depth, thicker pipe wall ...
Abstract Coastal area has high primary productivity and various ecosystems owing to richness nutrient from land. Biomass resources from this ecosystem are valuable and need to be preserved for environmental conditions. In Japan, coastal fishery flourishes as a way of application of biomass resources ...
Amino acids are building blocks for proteins in all animals. Based on growth or nitrogen balance, amino acids were traditionally classified as nutritionally essential or nonessential for mammals, birds and fish. It was assumed that all the “nutritionally nonessential amino acids (NEAA)” were synthesized ...
