The articles in this special section focus on robotic technologies for predictive maintenance of assets and infrastructure. Contemporary society depends significantly on the continuous, undisrupted functioning of the infrastructure system that provides us with energy, means of transport, and the extraction ...
Amebiasis is caused by the protozoan parasite Entamoeba histolytica (Eh), a potentially fatal disease occurring mainly in developing countries. How Eh interacts with innate host factors in the gut is poorly understood. Eh resides and feed in/on the outer colonic mucus layer and thus share an ecological ...
Cholera toxin, an 84-kDa multimeric protein and a major virulence factor of Vibrio cholerae, uses the ADP-ribosyltransferase activity of its A subunit to intoxicate host cells. ADP-ribosylation is a posttranslational modification of proteins, in which the ADP-ribose moiety of NAD+ is transferred to ...
Calcitonin (CT)/CT gene-related peptide (CGRP) family peptides (CT/CGRP family peptides) including CT, CGRP, adrenomedullin, amylin, and CT receptor-stimulating peptide have been identified from various vertebrates and perform a variety of important physiological functions. These peptides bind to two ...
Autism spectrum disorder (ASD) and intellectual disability (ID) are neurodevelopmental disorders with overlapping diagnostic behaviors and risk factors. These include embryonic exposure to teratogens and mutations in genes that have important functions prenatally. Animal models, including rodents and ...
Environments are shifting rapidly in the Circumpolar Arctic and Subarctic regions as a result of climate change and other external stressors, and this has a substantial impact on the health of northern populations. Thus, there is a need for integrated surveillance systems designed to monitor the impacts ...
Abstract A semi-submersible drilling rig chosen to perform the subsea well abandonment. The campaign consisted of abandoning four development wells which were completed with Horizontal Xmas Tree and having sustained casing pressure. In this paper, the methodology for performing the plug and abandonment ...
Abstract There is a demonstrated need for both technical and non-technical factors of the decommissioning industry which are the criteria of decision making in decommissioning project development. In Gulf of Thailand, there are huge numbers and volumes of offshore subsea pipelines expected to be decommissioned ...
Abstract This paper covers the End-of-Field Life management and abandonment planning for four subsea fields. Scope includes end-to-end planning from confirming cessation of production with the Regulator, to Abandonment Planning, actual Implementation and Execution. PETRONAS Procedures and Guidelines ...
Abstract 'As decommissioning has risen up the agenda for both Governments and oil and gas operators, the countries of Southeast Asia have adopted differing frameworks for the planning, permitting and execution of the decommissioning process. This paper presents a review of the frameworks adopted by ...
Abstract PT Pertamina Hulu Energi Offshore North-West Java (PHE ONWJ) presently operates a fleet of more than 200 fixed offshore platforms and nearly three quarters of these platforms have been in operation for more than 30 years. Under newly implemented Gross Split Production Sharing Contract (PSC) ...
Emergence of antibiotic resistant pathogenic bacteria poses a serious public health challenge worldwide. However, antibiotic resistance genes are not confined to the clinic; instead they are widely prevalent in different bacterial populations in the environment. Therefore, to understand development ...
Complete mitochondrial genomes play important roles in studying genome evolution, phylogenetic relationships, and species identification. Sea cucumbers (Holothuroidea) are ecologically important and diverse members, living from the shallow waters to the hadal trench. In this study, we present the mitochondrial ...
Multiple gonadotropin-releasing hormone receptors (GnRHRs) are present in vertebrates, but their differential physiological relevances remain to be clarified. In the present study, we identified three GnRH ligands GnRH1 (pjGnRH), GnRH2 (cGnRH-II), and GnRH3 (sGnRH) from the brain, and two GnRH receptors ...
The impact of temperature on photo-symbiotic relationships has been highly studied in the tropical reef-forming corals but overlooked in less charismatic groups such as solar-powered sacoglossan sea slugs. These organisms display one of the most puzzling symbiotic features observed in the animal kingdom, ...
Microalgae have been widely recognized as a valuable source of natural, bioactive molecules that can benefit human health. Some molecules of commercial value synthesized by the microalgal metabolism have been proven to display anti-inflammatory activity, including the carotenoids lutein and astaxanthin, ...
Background HIV self-testing (HIVST) addresses barriers to HIV diagnosis among men, but current approaches to distributing HIVST kits only reach a subset of the men requiring testing. Methods We conducted a pilot trial of the secondary distribution of HIVST kits through peer networks in fishing communities ...
Ecological considerations strongly necessitate the development of environmentally friendly antifouling paints. A promising alternative to biocide containing antifouling paints are fouling-release coatings, which are non-toxic and designed to prevent permanent attachment of marine organisms to the surface, ...
Free-ranging white-tailed deer (Odocoileus virginianus) are believed to be a self-sustaining reservoir for bovine tuberculosis (bTB) in northeastern Lower Michigan, USA. Although a comprehensive control program is in place and on-farm mitigation strategies to curtail bTB transmission between cattle ...
Abstract The evolution of antifreeze glycoproteins has enabled notothenioid fish to flourish in the freezing waters of the Southern Ocean. Whereas successful at the biodiversity level to life in the cold, paradoxically at the cellular level these stenothermal animals have problems producing, folding, ...
