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, ...
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 ...
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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
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, ...
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 fault of hydropower unit is affected by many factors, it is difficult to find the correspondent fault symptoms and causes through the theoretical analysis. Considering the disadvantages of BP neural network, such as slow convergence rate and getting into local extremum, the initial parameters are ...
Fine-grained object recognition aims at recognizing objects belonging to the same basic-level class such as dog, bird or fish, which is a challenging problem in computer vision. In this paper, we consider the problem of recognizing handbags that belong to a specific brand. In order to identify the subtle ...
Phishing which is a kind of theft that attempting to steal sensitive information, has become a major threat to people's daily life. Some researchers proposed some methods of anti-phishing based on the characteristics of fishing behaviors. This article will firstly introduce the field of phishing and ...
Microgrid technology can provide an effective technical approach for the new energy and renewable energy and the carbon emissions trading can provide favorable conditions for the grid-connected Microgrid operating economically. As a result, it establishs the optimal operation model of grid-connected ...
This work further investigates how weight based FSS (i.e. almost only use of local information) can impact in the automatic splitting the school for solution of multimodal bench mark problems. The chief modification to standard FSS, in order to produce the wFSS, was the introduction of a relationship ...
The increasing population in the developing countries has rendered wetlands vulnerable to land use changes. Remote sensing offers a rapid and efficient means of data acquisition of ecosystems in time and space. The present study was undertaken to identify changes in the Harike wetland, a Ramsar site ...
Predator–prey relationships are one of the most studied interactions in population ecology. However, little attention has been paid to the possibility of role exchange between species, despite firm field evidence of such phenomena in nature. In this paper, we build a mathematical model capable of reproducing ...
Play is the universal language of childhood and the time and opportunity to play is every child’s right. The role of play as a vehicle for communication, a tool for distraction and its value in the holistic development of a normal child is without dispute. The role and value of play increases proportionately ...
