Intermittency is ubiquitous in animal behavior. We depict a coordination problem that is part of the more general structure of intermittent adaptation: the adjustment-deployment dilemma. It captures the intricate compromise between the time spent in adjusting a response and the time used to deploy it: ...
The majority of ecotoxicological studies are performed under stable and optimal conditions, whereas in reality the complexity of the natural environment faces organisms with multiple stressors of different type and origin, which can activate pathways of response often difficult to interpret. In particular, ...
Background An important inter-individual variability in the response of insulin sensitivity following a fish oil supplementation has been observed. The objective was to examine the associations between single nucleotide polymorphisms (SNPs) within sterol regulatory element binding transcription factor ...
Objective The effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. Materials and Methods In this experimental study, we ...
Oncomelania hupensis is the sole intermediate host snail of Schistosoma japonicum in China. Snail control by molluscicide remains one of the most effective measures of schistosomiasis japonica control. A 50% wettable powder of niclosamide ethanolamine salt (WPN) is widely used for snail control in China. ...
Antimicrobial peptides (AMPs) play an important role in the innate defense mechanisms in humans and animals. We have isolated and studied a set of antimicrobial peptides from leukocytes of the Russian sturgeonAcipenser gueldenstaedtii belonging to a subclass of chondrosteans, an ancient group of bony ...
Introduction Risk factors and precipitants of gastro-oesophageal disease (GERD) differ widely in communities. We conducted an observational study to describe these risks, precipitants and clinical presentation of GERD patients at Kilimanjaro Christian Medical Centre (KCMC) in Tanzania. Methods We ...
A system for creating a rehydrated composition from a dehydrated precursor, where the precursor is in a reaction receptacle and is adapted to react chemically and/or physically with a heated liquid. The system includes a heated liquid delivery system which itself includes a liquid storage tank, a pump ...
Ship detection is nowadays quite an important issue in tasks related to sea traffic control, fishery management and ship search and rescue. Although it has traditionally been carried out by patrol ships or aircrafts, coverage and weather conditions can become a problem. Synthetic aperture radars can ...
The objective of the European FP7 project NeXOS (Next generation Low-Cost Multifunctional Web Enabled Ocean Sensor Systems Empowering Marine, Maritime and Fisheries Management) is to develop cost-efficient innovative and interoperable in-situ sensors deployable from multiple platforms to support the ...
A growing concern about the health of the world oceans resulting from multiple stressors as for instance effects of climate change and increasing offshore activities leads to the need of better observational tools and strategies. The objective of the NeXOS project is to serve those needs by developing ...
In the realm of marine fish farming, there is increased focus on employing numerical models and tools to optimize production. A model describing the distribution of pelleted fish feed in time and space within a sea cage, a process which is essential for proper fish growth and welfare, has been established, ...
In running the activities, the Goverment requires the data and information that are real time, accurate and relevant to the field of development planning. In short, application monitoring system for fishery sea resources is a mechanism of monitoring integrated activity between staff whos are in the ...
Economic incentives to harvest a species usually diminish as its abundance declines, because harvest costs increase. This prevents harvesting to extinction. A known exception can occur if consumer demand causes a declining species' harvest price to rise faster than costs. This threat may affect rare ...
Despite advances in underwater technology, human divers are still employed to carry out a wide variety of dangerous underwater tasks. To enable a diver to complete tasks safer and more efficiently, it is proposed that an Underwater Robotic Assistant (UWRA) could act as a robotic dive buddy. For example, ...
An inflatable upper arm swimming aid, comprising a strip (1) with a first end face (9) and a second end face (10) opposite the first end face (9) and having a) one or more inflatable chambers (2) forming or forming together an inflatable ring cavity of the strip (1), and b) a connecting section (3), ...
Background The drastic decline in the abundance of Caribbean acroporid corals (Acropora cervicornis, A. palmata) has prompted the listing of this genus as threatened as well as the development of a regional propagation and restoration program. Using in situ underwater nurseries, we documented the influence ...
Reproductive isolation at the gamete stage has become a focus of speciation research because of its potential to evolve rapidly between closely related species. Conspecific sperm precedence (CSP), a type of gametic isolation, has been demonstrated in a number of taxa, both marine and terrestrial, with ...
CpG-oligodeoxynucleotides (CpG-ODN) are potent immune stimuli being developed for use as adjuvants in different species. Toll-like receptor 9 (TLR9) is the cellular receptor for CpG-ODN in mammalian cells. The CpG-ODN with 18–24 deoxynucleotides that are in current use for human and mouse cells, however, ...
