Saline environments, such as marine and hypersaline habitats, are widely distributed around the world. They include sea waters, saline lakes, solar salterns, or hypersaline soils. The bacteria that live in these habitats produce and develop unique bioactive molecules and physiological pathways to cope ...
Background The most critical step in the pearl formation during aquaculture is issued to the proliferation and differentiation of outer epithelial cells of mantle graft into pearl sac. This pearl sac secretes various matrix proteins to produce pearls by a complex physiological process which has not ...
The ability to identify odors in the environment is crucial for survival and reproduction. However, whether olfactory processing in higher-order brain centers is influenced by an animal’s physiological condition is unknown. We used in vivo neuron and local field potential (LFP) recordings from the ventral ...
Osteoglossiformes represents one of the most ancestral teleost lineages, currently widespread over almost all continents, except for Antarctica. However, data involving advanced molecular cytogenetics or comparative genomics are yet largely limited for this fish group. Therefore, the present investigations ...
Mycobacterium chelonae is a member of the Mycobacterium chelonae-abscessus complex and a cause of opportunistic disease in fish, reptiles, birds, and mammals including humans. Isolates in the complex are often difficult to identify and have differing antimicrobial susceptibilities. Thirty-one previously ...
Natural resource rules exist to control resources and the people that interact with them. These rules often fail because people do not comply with them. Decisions to comply with natural resource rules often are based on attitudes about legitimacy of rules and the perceived risks of breaking rules. Trust ...
ABSTRACT Hydrogen embrittlement occurs when a material’s mechanical strength is weakened by the penetration of atomic hydrogen inside the material, the hydrogen sources are diverse and they all intervene in this phenomenon. Plating processes and cathodic protection induce the production of hydrogen ...
ABSTRACT Thermally sprayed aluminum (TSA) has been used in offshore oil and gas infrastructure for decades. Their effectiveness in mitigating corrosion of steel structures in presence of seawater has been proven over the years. However, very little work is reported on the performance of TSA in other ...
ABSTRACT Corrosion Under Insulation (CUI) is a major challenge for different process industries. Today it is managed in many ways, ranging from full removal of insulation to minimal maintenance, including some inspection methods with insufficient non-destructive testing. These extremes exhibit a lack ...
ABSTRACT This study discusses a new coating method to protect type 316L stainless steel (SS) from pitting corrosion in high chloride environments. The SS surface was coated using a simple, eco-friendly method, and sunflower oil (SunFO) was used as a base coating and binder for MoS2. The coated surface ...
ABSTRACT The use of dry coating on Premium OCTG connections to replace both storage and running compounds presents numerous benefits for end-users. As well as improving running performances, it keeps the well clean by preventing the discharge of dope to the environment and into the well bore and it ...
ABSTRACT DNVGL-RP-B401 “Cathodic Protection Design” is widely used as a design code for cathodic protection (CP) of permanently installed offshore structures associated with production of oil and gas.1 CP design parameters in RP B401 are consistently selected using a conservative approach. Adherence ...
ABSTRACT Styrenic materials, utilized in subsea wet insulation, have been exposed in long-term tests for 12 months at elevated temperatures and pressures in seawater according to ISO 12736:2014. The performance of these materials under this harsh exposure regiment shall be presented and compared to ...
ABSTRACT In natural seawater, many parameters might influence the cathodic protection current demand such as potential, temperature, dissolved oxygen content, biofilm and fouling activity, and calcareous deposit formation. The actual deepsea environment cannot be easily reproduced at laboratory scale. In ...
ABSTRACT All protective coatings are thoroughly tested using accelerated laboratory tests. Accelerated testing has the advantage of providing data and results in a relatively short timeframe, and the conditions of testing are pre-defined and controlled throughout the test. However, accelerated testing ...
ABSTRACT Temporary coatings in conjunction with cathodic protection (CP) in seawater have been used in this paper for solving the contradiction between big initial current density and small mean current density. The repairing effect of calcareous deposits produced during CP on the coating deterioration ...
ABSTRACT Almost every piece of equipment in the Oil and Gas industry requires the use of bolted joints due to numerous advantages they offer; protecting them against corrosion is mandatory. Most anti-corrosion coatings on bolts don’t offer a consistent tightening, as their nut factor changes, the nut ...
ABSTRACT MIC or microbiological induced corrosion is a serious threat in offshore applications such as wind turbine monopile foundations and mooring chains. This type of localized attack may lead to high corrosion rates affecting the S/N curve which determines the safe operation life of the structure. ...
In this study, biogenic amine content in Pa (green onion) kimchi and Gat (mustard leaf) kimchi, Korean specialty kimchi types, was determined by high-performance liquid chromatography (HPLC). Many kimchi samples contained low levels of biogenic amines, but some samples had histamine and tyramine content ...
Minimally processed and ready-to-eat (RTE) seafood products are gaining popularity because of their availability in retail stores and the consumers’ perception of convenience. Products that are subjected to mild processing and products that do not require additional heating prior to consumption are ...
