Fuel effectivization and emission reductions have been on the forefront of research for marine power system solutions. The reduction in fuel use was originally motivated by savings on the principal operating cost of vessels. The need to reduce emissions, both CO2 for the global environment and nitrous ...
The Pacific Islands Fisheries Science Center deploys the Modular Optical Underwater Survey System (MOUSS) to estimate species-specific, size-structured abundance of commercially-important fish species in Hawaii and the Pacific Islands Regions. The MOUSS is an autonomous stereo-video camera system designed ...
Fishing has the highest rate of occupational fatalities in the USA, per the Bureau of Labor Statistics, and Alaska's waters are the deadliest, per Coast Guard statistics [1]. Many fishing fatalities stem from small boats, 44 feet in length or less. Small boats can sink or tip for many reasons including ...
All commercial fishery species harvested globally either live on or near the seabed (also referred to as the benthos or benthic environment) or employ life history strategies or behaviors linked to benthic processes. The act of pursuing and catching benthic and demersal species requires operating fishing ...
The paper focuses on the problem of equipment of small fishing vessels mapping systems. Such systems are complex technical complexes are not intended for installation in small vessels. The paper includes result's description of developed geopositioning system with dynamic informational collection support ...
SEAPIX is a new Dual Steerable multibeam echosounder (DS-MBES) with an original architecture using a steerable symmetric Mills Cross. This configuration allows to image water column and sea bottom in both athwart ship and fore-and-aft direction with steering capability, covering 120° × 120° under ship ...
Abstract Background Invasive non-typhoidal Salmonella (iNTS) disease is a well-described cause of mortality in children and human immunodeficiency virus (HIV)-infected adults in sub-Saharan Africa. Additionally, there is an ill-defined burden of iNTS disease in Southeast Asia. Methods Aiming to ...
Abstract Empirical investigations of the impacts of anthropogenic stressors on marine organisms are typically performed under controlled laboratory conditions, onshore mesocosms, or via offshore experiments with realistic (but uncontrolled) environmental variation. These approaches have merits, but ...
Background: Considering the importance of hospital wastewaters as potential reservoirs for the dissemination of bacterial pathogens such as Escherichia coli and antibiotic resistance genes in the environment, the need for such information becomes imperative. Methods: E. coli strains were isolated ...
Previous studies revealed that Honghu Lake was polluted by trace elements due to anthropogenic activities. This study investigated the spatial distribution of trace elements in Honghu Lake, and identified the major pollutants and control areas based on the fuzzy health risk assessment at screening level. ...
Sixty-eight cefotaxime-resistant Escherichia coli isolates were recovered from different water environments in Northern Thailand. Isolates were mostly resistant to ceftazidime and aztreonam (>90%). The most common extended-spectrum β-lactamase-encoding gene was blaCTX-M-group 1 (75%) followed by ...
Introduction Saltwater intrusion and salinisation have contributed to drinking water scarcity in many coastal regions globally, leading to dependence on alternative sources for water supply. In southwest coastal Bangladesh, communities have few options but to drink brackish groundwater which has been ...
The genus Cyprinivirus consists of a growing list of phylogenetically related viruses, some of which cause severe economic losses to the aquaculture industry. The archetypal member, cyprinid herpesvirus 3 (CyHV-3) causes mass mortalities worldwide in koi and common carp. A CyHV-3 mutant was described ...
Animals store metabolic energy as electrochemical gradients. At least 50% of mammalian energy is expended to maintain electrochemical gradients across the inner mitochondrial membrane (H+), the sarcoplasmic reticulum (Ca++), and the plasma membrane (Na+/K+). The potential energy of these gradients can ...
Land use and Land cover plays a vital role in the aspect of change detection studies. Land use represents how the land is being used. It includes categories like agriculture, industrial lands. Land cover refers to natural or manmade properties. It includes waterbodies and vegetation. The ratio of Land ...
This paper refers to an integrated trigeneration systems dedicated for isolated residents with energy independence. It is about solar photovoltaic and solar thermal systems based micro-combined cooling, heating and power systems in the 1 to 10 kW scale for residential and light commercial applications. ...
Aquaculture planning and development is a very important process that will enhance and mentor the growth of the sector, while ensuring its long-term sustainability with environmentally and economically. In this proposed work, we have considered two rivers; Netravati and Sita which flows west coastal ...
Fish farms pretend to be the sustainable option to provide fish. The water quality is very important to ensure the fish performance. Thus, the monitoring of the water quality is crucial in order to automatize different process in facilities. In this paper, we present a system to monitor the turbidity ...
Aquaculture has resorted to the use of technology to make control of important variables and improve production. There were two problems observed in the Marine Aquaculture Station — EMA of the Federal University of Rio Grande, more specifically related to the aeration of the culture tanks to pisciculture ...
This paper presents the development of a robotic cleaning solution for a fish processing plant. The project is currently at the stage of a first prototype consisting of a serial manipulator, a vertical linear axis and a rotational axis for the vertical axis. The purpose of the prototype is to validate ...
