ABSTRACT The authors have tackled the environmental assessment problem about Cambodian shoreline since 2008, and performed many observations about the geographical map, water current, weather and etc. This study reports the observation result about the feature of topography, tidal change and weather. ...
ABSTRACT A three-classification model is established to analyze factors that have influence on severity of water traffic accidents with SVM, on this basis, this paper made an empirical combined with Cross Validation by use of the traffic accident data from Shanghai Maritime Safety Administration, which ...
Abstract Agbami Well-BB was completed as a dual zone frac pack intelligent completion. Barely a month after the well was put on production, while carrying out optimization on the well to increase production, flow from the upper zone decreased and further testing indicated that the zone’s production ...
Fragrances and malodors are ubiquitous in the environment, arising from natural and artificial processes, by the generation of volatile organic compounds (VOCs). Although VOCs constitute only a fraction of the metabolites produced by an organism, the detection of VOCs has a broad range of civilian, ...
Abstract Individual growth is an important parameter and is linked to a number of other biological processes. It is commonly modeled using the von Bertalanffy growth function ( VBGF), which is regularly fitted to age data where the ages of the animals are not known exactly but are binned into yearly ...
Abstract While individual growth ultimately reflects the quality and quantity of food resources, intra and interspecific interactions for these resources, as well as individual size, may have dramatic impacts on growth opportunity. Out‐migrating anadromous salmonids make rapid transitions between habitat ...
The larval phase of the fish life cycle has the highest mortality, particularly during the transition from endogenous to exogenous feeding. However, the transcriptional events underlying these processes have not been fully characterized. To understand the molecular mechanisms underlying mouth-opening ...
Chemical biocides have been widely used as marine antifouling agents, but their environmental toxicity impose regulatory restriction on their use. Although various surrogate antifouling biocides have been introduced, their comparative effectiveness has not been well investigated partly due to the difficulty ...
Predator-prey relationships are often perceived simply as a situation in which a predator enhances its own fitness while reducing the fitness of its prey. However, this relationship may become reversed when the prey feeds on the juvenile predator stages. We investigated this phenomenon in a model asp ...
Many studies classifying Gracilaria species for the exploitation of agarophytes and the development of the agar industry were conducted before the prevalence of molecular tools, resulting in the description of many species based solely on their morphology. Gracilaria firma and G. changii are among the ...
ABSTRACT In this paper, we describe how to use multi-variable decision analysis to facilitate offshore oil and gas platform decommissioning. We implemented decision analysis as a software tool (PLATFORM) to clarify and evaluate decommissioning alternatives against a comprehensive set of objectives, ...
ABSTRACT A flexible riser at that end of its service life in the Gulf of Mexico was planned for decommissioning, and was found via positive pressure annulus testing to have a breached outer sheath in the splash zone region. The decommissioning plan included abandonment of the riser from hang-off to ...
ABSTRACT Wave elevation around a cage array used in aquacultural engineering with different levels of biofouling are numerically investigated. The porous-media fluid model is introduced to model both the clean and the biofouled netting. An oscillating-boundary method is used to generate waves at one ...
ABSTRACT With conventional sources of uranium forecasted to be depleted within the century, research into the harvesting of uranium from seawater, which is estimated to contain 1000 times more uranium than land, is crucial to determining the continued viability of nuclear power generation. Recent studies ...
ABSTRACT Large-scale kelp raft culture system is under combination action of wind, wave and current. The safety and reliability of the facility directly affect the whole aquaculture production. In this paper, the calculation and analysis are based on hanging culture form of a kelp raft culture system. ...
ABSTRACT Fish cages in the open sea are exposed to cycle wave loads during their service life, and thus the fatigue reliability of mooring chains should be re-assessed to ensure the safety status. A numerical model was adopted to calculate the tension force of mooring chains. A nonlinear contact finite ...
ABSTRACT In this study, the k-ω SST model is applied to analyze the vortex structure around the net cage in current. To validate the numerical simulation, a series of physical model tests were conducted. The results indicate the numerical model can accurately simulate the flow field around the net ...
ABSTRACT In this study, the behavior of the coupled mooring system and floating multibody body is analyzed. The equations of motions for multibody and mooring line are introduced. To formulate combined equations of motion, the concept of the constrained force is applied. The combined equations of motion ...
ABSTRACT Background: Achieving nutritional goals of infants and young children while maintaining the intake of local and culture-specific foods can be a daunting task. Diet optimisation using linear goal programming (LP) can effectively generate optimal formulations incorporating local and culturally ...
Carotenoids are organic lipophilic yellow to orange and reddish pigments of terpenoid nature that are usually composed of eight isoprene units. This group of secondary metabolites includes carotenes and xanthophylls, which can be naturally obtained from photosynthetic organisms, some fungi, and bacteria. ...
