Summary Hard substrates associated with offshore oil and gas platforms can contribute to the productivity of marine ecosystems, thereby generating local and regional economic benefits. These benefits form the basis for incorporating the platform into a rigs-to-reefs program when it is retired or for ...
The effects of ionizing radiation on biological cells have been reported in several literatures. Most of them were mainly concerned with doses greater than 0.01 Gy and were also concerned with gamma rays. On the other hand, the studies on very low dose fast neutrons (VLDFN) are rare. In this study, ...
The teleost fishes represent over half of all extant vertebrates; they occupy nearly every body of water and in doing so, occupy a diverse array of environmental conditions. We propose that their success is related to a unique oxygen (O2) transport system involving their extremely pH-sensitive haemoglobin ...
Traditionally, exploration of genetic variance in humans, plants, and livestock species has been limited mostly to the use of additive effects estimated using pedigree data. However, with the development of dense panels of single-nucleotide polymorphisms (SNPs), the exploration of genetic variation ...
Adolescent obesity is associated with both immediate and longer-term health implications. This study aims to identify dietary patterns among a nationally representative sample of Lebanese adolescents aged between 13 and 19 years (n 446) and to assess the association of these patterns with overweight ...
Tc1-like transposons consist of an inverted repeat sequence flanking a transposase gene that exhibits similarity to the mobile DNA element, Tc1, of the nematode, Caenorhabditis elegans. They are widely distributed within vertebrate genomes including teleost fish; however, few active Tc1-like transposases ...
In recent years, traceability systems have been developed as effective tools for improving the transparency of supply chains, thereby guaranteeing the quality and safety of food products. In this study, we proposed a cattle/beef supply chain traceability model and a traceability system based on radio ...
Enhancing the production of aquatic animals is crucial for fishery management and aquaculture applications. Ovaries are specialized tissues that play critical roles in producing oocytes and hormones. Significant biochemical changes take place during the sexual maturation of Portunus trituberculatus, ...
This demo presents a suite of serious Kinectâ„¢ - based games for rehabilitation. The game embodies three metaphors and corresponding game mechanics, for three exercise movements: elbow flexion and extension (fisherman), shoulder abduction and adduction (moon spaceship), and knee flexion and extension ...
To find acoustic signature of diver equipped with atmospheric diving suit (ADS), a logarithmic normalized frequency-domain multi-band matched-filter (LNMF) algorithm is presented, which can mitigate the influence of the background noise and short-duration transient interference. Based on experimental ...
Cognitive signal processing has been intensively studied over the past years. Nevertheless, cognitive sonar systems only draw little attention in the research community. In this paper the signal processing of a cognitive sonar system for diver detection is shown in detail. It is inspired by the target-detection ...
Divers have to perform technical underwater tasks in dangerous and unstructured environments. To reduce a diver's workload and improve overall safety, an underwater robotic assistant (UWRA) could be deployed with the diver. The UWRA could assist the diver in navigation, quickly ferry tools from the ...
Using an Autonomous Underwater Vehicle (AUV) for close-proximity operations (e.g., close to the seafloor, a vessel, or divers) requires robust, precise vehicle control. When performing joint human-robot operations, a Robotic Diver Assistant can perform tasks such as tool carrying, worksite illumination, ...
When marine disasters occur, it is sometimes necessary for search and rescue dive teams to begin rescue and recovery efforts, even before a complete assessment of the underwater safety situation can be conducted. This makes the job of the Coast Guard personnel in charge of these types of operations ...
The supraneural body was identified in the adult lamprey, and its secretions induced the death of a variety of tumor cells but had no effect on normal cells. The cell secretions from different lamprey tissues were separated, and these secretions killed human tumor cells to varying degrees. The cell ...
This paper conveys the findings of the first phase of a longitudinal study into climate change adaptation in Atlantic Canada. Men and women from 10 coastal communities in three provinces (Quebec, New Brunswick, and Prince Edward Island) were interviewed to better understand how both sexes perceived ...
Processing marine-mammal signals for species classification and monitoring of endangered marine mammals are problems that have recently attracted attention in the scientific literature. Currently, the detection of signals of interest is typically accomplished through a combination of visual inspection ...
We developed a novel underwater atomic force microscopy (UAFM) system that is mountable on underwater vehicles or submersible seafloor platforms. This system is intended for in situ observation of microorganisms and microparticulates suspended and dispersed in deepwater near hydrothermally active features, ...
Nearshore sea surface temperatures show both strong seasonal trends and rapid changes associated with local weather events. As a result, commercial fishing operations search and rescue services, and recreational users have a very limited capability to predict expected sea surface temperatures for any ...
This paper describes research to determine the effectiveness of forward-looking sonar as a means to safely navigate vessels in frontiers such as the Arctic and other regions that may be lacking recent or comprehensive hydrographic survey. Key elements of this investigation include the range at which ...
