The turquoise killifish, Nothobranchius furzeri, is a promising vertebrate model in ageing research and an emerging model organism in genomics, regenerative medicine, developmental biology and ecotoxicology. Its lifestyle is adapted to the ephemeral nature of shallow pools on the African savannah. Its ...
CD4 is a nonpolymorphic transmembrane glycoprotein molecule that is expressed on the surface of T-helper cells and plays an essential role in the immune response. It functions as a coreceptor with the T-cell receptor by binding to major histocompatibility complex class II on the surface of dendritic ...
The vertebrate stress response enables individuals to react to and cope with environmental challenges. A crucial aspect of the stress response is the elevation of circulating glucocorticoids. However, continued activation of the stress response under repeated exposure to stressors can be damaging to ...
Foams were introduced to enhanced oil recovery (EOR) for the purpose of improving sweep efficiency via mitigating gas breakthrough. In prior works, well-defined nanocellulose-based nanofluids, which can well stabilize foam film as a green alternative to reduce the environmental impact, were successfully ...
Abstract Among the many goals of environmental management in Saudi Aramco, protection of special environmental areas is recognized as high priority to both the company and the Kingdom of Saudi Arabia. In line with this objective, Safaniya Onshore Producing Department (SONPD) designated Safaniya area ...
Abstract New downhole coiled tubing (CT) technology was used to facilitate the success of a challenging fishing intervention and to verify the reliability and accuracy of CT operations/simulation software. The technology supplies the newly designed bottomhole assembly (BHA) with continuous power from, ...
The subject well is a recently drilled and completed in Cambay field offshore in West coast of India. After landing the completion, two mechanical plugs were installed to nipple down BOP and nipple up X-mas tree. The plugs were installed in a 3.875" tubing hanger profile and in a 3.813" SC-TRSSSV selective ...
Abstract Each topside structure due to be decommissioned requires a thorough case-by-case evaluation for best abandonment options. With the prospect of conducting decommissioning campaigns to reduce cost, decommissioning engineers still need to conduct multiple individual decommissioning options assessments ...
Sustainably feeding the growing world population is a major challenge. With 70% of the Earth’s surface covered by oceans, the potential of ocean farming is huge. However, the development of offshore aquaculture systems is in its infancy. This paper discusses and presents concept designs for offshore ...
Abstract Potential applications for wave energy cover the spectrum from powering watt-scale maritime sensors to generating electricity at megawatt-scale. These applications include energy generation for: ocean observation, communications, autonomous underwater vehicles recharging, isolated community ...
Abstract The paper presents a cost benefit analysis of using polymer mooring components in the mooring system design of the Maine Aqua Ventus I (MAV1) floating offshore wind turbine (FOWT) project. Polymer components in mooring lines can offer new mooring system responses, which can be tailored to ...
ABSTRACT In the framework of FP7 funding scheme, the project H2OCEAN (grant agreement n. 654871) has been developed, investigating a proof-of-concepts of a multi-use ocean platform, able to harvest energy, produce and store energy in the form of compressed H2, together with a multi-trophic aquaculture ...
ABSTRACT Icing affects the stability of the ship and increases the ice resistance, and poses a major threat to the ship navigation. The existing studies on ship icing focus more on the freezing of supercooled water droplets but ignore the microscopic growth process of ice. This paper realized the simulation ...
ABSTRACT In this study the performance of the Internet of Fish (IoF) concept, a real-time acoustic positioning and fish monitoring system, was assessed in a commercial marine fish farm in Norway. Central to the IoF concept is the Synchronisation and LoRa Interface Module (SLIM), which is a battery ...
ABSTRACT This paper examines the effect of including a tuna aquaculture component to a proposed integrated system utilizing ocean energy and microalgae to produce biofuel. Cost-benefit analysis and carbon footprint estimation show a significant improvement on both economic and environmental performance ...
ABSTRACT In this paper, based on the correlation between meteorological factors and sea ice area from 1958 to 2015, we study sea ice area change and its driving factors. The results show that the maximum and average of sea ice area showed a downward trend, with annual change rates of −0.33±0.18% and ...
ABSTRACT The marine aquaculture sector is a rapidly growing industry, operating mainly in near-shore areas as of now. Due to the increasing demand for marine proteins and in line with the sustainable development goals, researchers, industry, and policy makers are shifting their focus to offshore systems. ...
Abstract This paper will discuss further on the recent decommissioning project of fields which has been completed on November 2017. These two platforms had been totally removed and became an artificial reef at Sarawak water in Malaysia. This paper will show the activities and best practices; the team ...
Traditional planting and aquaculture has the problem of large consumption of water resources and land resources, and the water environmental pollution is also a difficult problem facing human beings. Population growth and food safety issues have promoted the concept of aquaponics--a recycling ecological ...
The energy consumption for aquaculture in Vietnam, especially shrimp farming industry, has continued rising considerably in recent years due to the expand of shrimp production to meet food demand. Most of energy demand at shrimp farms is consumed by aeration system which uses electric motors to drive ...
