The growing capacity to process and store animal tracks has spurred the development of new methods to segment animal trajectories into elementary units of movement. Key challenges for movement trajectory segmentation are to (i) minimize the need of supervision, (ii) reduce computational costs, (iii) ...
Abstract Real-time monitoring of downhole location, pressure, and temperature is currently available for many coiled tubing (CT) operations. A newly-developed tension, compression, and torque (TCT) data monitoring capability in real-time improves operational efficiency and accelerates well recovery ...
Abstract Shale play assets are exploited using horizontal wells in which measuring and controlling top-of-tool forces are necessary for positioning tools. Methods currently applied to deal with these forces are inefficient. In traditional vertical wells, tool transportation relies on gravity force ...
Abstract Technical challenges and considerations for different aspects of floating liquefied natural gas (FLNG) terminals are explained and solutions are compared. This paper considers design aspects of ship hull, LNG storage, safety, cargo transfer and station-keeping of the terminals. Drawing on ...
Abstract Decommissioning projects are rare in this region (South East Asia), thus opportunities for benefitting from firsthand experience are quite limited. According to The Offshore O&G Decommissioning Market 2013-2023, similarly throughout the North Sea, the Norwegian sector has limited experience ...
Abstract Straits of Malacca Exploration Campaign marks PETRONAS' first oil/gas well drilling in the region of West Coast of Peninsular Malaysia. Three (3) exploration wells were drilled in a period of four (4) months. This paper will highlight the challenges, lessons learnt and key to success of this ...
Abstract This paper presents the overview of a R&D project "Zipangu of the Sea", focusing on the sub-R&D project supervised by National Maritime Research Institute of Japan. Consisting of 7 sub-projects, main object of the Zipangu of the Sea project is the development of core technologies required ...
Biological armors such as mollusk shells have long been recognized and studied for their values in inspiring novel designs of engineering materials with higher toughness and strength. However, no material is invincible and biological armors also have their rivals. In this paper, our attention is focused ...
Because the ability to hide in plain sight provides a major selective advantage to both prey and predator species, the emergence of the striking colouration of some animal species (such as many coral reef fish) represents an evolutionary conundrum that remains unsolved to date. Here I propose a framework ...
This study aimed to search for a molecular marker for targeted epithelial growth factor receptor (EGFR) inhibitor Icotinib by analyzing protein expression and amplification of EGFR proto-oncogene in esophageal squamous cell carcinoma (ESCC) patients. Immunohistochemistry and fluorescence in situ hybridization ...
Background Omega3 polyunsaturated fatty acids (PUFAs) are related to several diseases, including smoking. The aim of this study was to evaluate the relationship between omega-3 intake and tobacco smoking, taking into account the qualitative differences in dietary intake between smokers and non-smokers, ...
Background The centromere plays a crucial role in ensuring the fidelity of chromosome segregation during cell divisions. However, in cancer and constitutional disorders, the presence of more than one active centromere on a chromosome may be a contributing factor to chromosome instability and could ...
Background Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others. Differential introgression of molecular or phenotypic markers can thus provide insight into factors ...
Background Nodding syndrome (NS) is an epilepsy disorder occurring in children in South Sudan, northern Uganda and Tanzania. The etiology of NS is unknown, but epidemiological studies demonstrate an association between NS and onchocerciasis. Methods Between November 2013 and July 2015 we visited ...
In this work we investigated the between-colony spatial, behavioural and trophic segregation of two sub-populations of the elusive Macaronesian shearwaters Puffinus baroli breeding only ~340 km apart in Cima Islet (Porto Santo Island) and Selvagem Grande Island. Global location sensing (gls) loggers ...
The conservation status and taxonomy of the three gadfly petrels that breed in Macaronesia is still discussed partly due to the scarce information on their spatial ecology. Using geolocator and capture-mark-recapture data, we examined phenology, natal philopatry and breeding-site fidelity, year-round ...
More than 20 years ago, the first e-line coiled tubing drilling (CTD) systems were introduced. Since then, the technology has evolved and proven to be an efficient, economic means of enabling additional production from aging oil and gas fields. These systems are now established as a standard, viable ...
The studies evaluating the impact of environmental pollution on aquatic organisms have had a growing concern in recent decades. The Ocoa River runs through Villavicencio city, receiving the wastewater produced in the city. To date studies reporting the effect and the consequences of Ocoa River pollution ...
Abstract The Sumandak field is located offshore Sabah, northwest of Labuan Island, in Malaysia. The majority of the reservoirs in this field are oil producers subject to sand production at some point during well life. The subject well was completed using a typical completion design for the current ...
Stackable straddle systems are presented as an effective method of increasing oil production rates in a highly deviated extended reach borehole, by isolating or reducing gas production from high influx zones. In the case study presented in this paper an openhole gravel pack (OHGP) production well was ...
