Quantifying the energy requirements of animals in nature is critical for understanding physiological, behavioural, and ecosystem ecology; however, for difficult-to-study species such as large sharks, prey intake rates are largely unknown. Here, we use metabolic rates derived from swimming speed estimates ...
Abstract Traditional feasibility studies for remediation projects consider factors including cost, implementation risks, reliability and environmental protection. However, traditional studies do not address corporate and stakeholder desires for more sustainable business practices. Approaches are needed ...
Abstract As U.S. shale play activities move from appraisal to production phase, it is increasingly difficult for surface operations to avoid impacts to environmentally sensitive wetlands and streams. Many shale plays are located in areas more visible to the general public than ever before in the history ...
Abstract Senior executives across the oil and gas industry are increasingly vocal about the impact of environmental and social issues on their business: CEOs presenting at the last two CERAWeek conferences (and other industry events) on insights into the energy future have repeatedly highlighted maintaining ...
Abstract This paper examines the potential risk of using controlled implosions as a new technique to securely seal an offshore leaking oil pipe. Massive amount of toxins and radioactive waste are produced by offshore oil leaks. These leaks can have negative impact on marine life and can threaten the ...
An environmental risk assessment (ERA) for the aquatic compartment in Europe from human use was developed for the old antibiotic Trimethoprim (TMP), comparing exposure and effects. The exposure assessment is based on European risk assessment default values on one hand and is refined with documented ...
Marine microorganisms are important for the global nitrogen cycle, but marine nitrifiers, especially aerobic nitrite oxidizers, remain largely unexplored. To increase the number of cultured representatives of marine nitrite-oxidizing bacteria (NOB), a bioreactor cultivation approach was adopted to first ...
Mollusk remains are abundant in archaeological sites in the Guanzhong Basin of Northwestern China, providing good opportunities for investigations into the use of mollusks by prehistoric humans. Here we report on freshwater gastropod and bivalve mollusks covering the time interval from about 5600 to ...
The recently completed European Census of Marine Life, conducted within the framework of the global Census of Marine Life programme (2000–2010), markedly enhanced our understanding of marine biodiversity in European Seas, its importance within ecological systems, and the implications for human use. ...
ABSTRACT The shift to use environmentally friendly technologies throughout future space-related launch programs prompted a study aimed at replacing current petroleum and solvent-based corrosion preventive compounds (CPCs) with environmentally friendly alternatives. The work in this paper focused on ...
ABSTRACT ABSTRACT The application of coatings has been a method used to prevent or control microbiologically influenced corrosion (MIC), mainly on carbon steel, a less corrosion resistant metal often used in various industries because of its low cost. This study aimed at evaluating comparatively the ...
ABSTRACT Sagging failures occurring immediately after spraying in a preerection ship block are uncommon when solvent-borne alkyd coatings have been used, but there are not conditions that induce the sagging failures, such as high coating thickness and humidity. These failures cause additional workload ...
ABSTRACT In some cases submarine pipelines are installed with a direct electric heating system to avoid formation of wax and hydrates. The principle is that an alternating current is applied between each end of the pipeline and heat is generated in the pipe material. The pipe is fully electrically ...
ABSTRACT Many kinds of organic coatings have been applied to protect ships in various corrosive environments. Mainly epoxy coating systems have been used to protect water ballast tanks of ships from corrosion. Since aquatic nuisance species via a ship’s ballast water have induced detrimental ecological ...
ABSTRACT Offshore steel pipelines are typically shop coated with a robust anticorrosive coating such as fusion bonded epoxy or a multilayer polyolefin system. Cathodic protection (CP) in the form of sacrificial anodes is also normally installed to help provide corrosion control. Since, these offshore ...
ABSTRACT A majority of military hardware; ground vehicles, airplanes, ships and support equipment such as weapons and generators are made primarily of metal. In order to protect the metal from corrosion Chemical Agent Resistant Coatings or CARC is widely applied on military vehicles. CARC system is ...
ABSTRACT A field testing of corrosion and biofouling behavior of eight copper alloys was carried out at the Portsmouth Harbor, USA (North Atlantic Ocean). The plate specimens of the alloys were submerged for one year to investigate the effect of seawater exposure on corrosion and accumulation of biofouling. ...
ABSTRACT It is well understood that environmentally-friendly production chemicals are required in the oilfield production industry, particularly in regions such as the North Sea where environmental criteria for application is considered to be the global standard. Efforts are now underway to phase-out ...
Background The African annual fish Nothobranchius furzeri has over recent years been established as a model species for ageing-related studies. This is mainly based on its exceptionally short lifespan and the presence of typical characteristics of vertebrate ageing. To substantiate its role as an alternative ...
Introduction The current study uses the Language Independent Functional Evaluation (L.I.F.E.) to evaluate disability in a smaller Ghanaian coastal town to characterize the extent and nature of disability. The L.I.F.E. is a video animated, language free equivalent of the standard 10-item verbal/written ...
