We present a simple model to study Lévy-flight foraging with a power-law step-size distribution [Image Omitted] in a finite landscape with countable targets. We find that different optimal foraging strategies characterized by a wide range of power-law exponent μopt, from ballistic motion (μopt → 1) ...
Certain RNA and DNA viruses that infect plants, insects, fish or poikilothermic animals encode Class 1 RNaseIII endoribonuclease-like proteins. dsRNA-specific endoribonuclease activity of the RNaseIII of rock bream iridovirus infecting fish and Sweet potato chlorotic stunt crinivirus (SPCSV) infecting ...
Background Multi-factorial intervention studies have been found to be successful in the initiation of lifestyle changes. However, little is known about the longer-term maintenance of health behavior improvements. The purpose of this study was to investigate whether improvements in physical activity ...
Background MHC class I (MHCI) molecules are the key presenters of peptides generated through the intracellular pathway to CD8-positive T-cells. In fish, MHCI genes were first identified in the early 1990′s, but we still know little about their functional relevance. The expansion and presumed sub-functionalization ...
Guppies have successfully established populations in places with thermal regimes very different from the Tropical conditions in their native range. This indicates a remarkable capacity for thermal adaptation. Given their vulnerability to predation as juveniles, acute changes in temperature, which can ...
Activation is an essential process that accompanies fertilisation in all animals and heralds major cellular changes, most notably, resumption of the cell cycle. While activation involves wave-like oscillations in intracellular Ca2+ concentration in mammals, ascidians and polychaete worms and a single ...
Variation in habitat quality is common across terrestrial, freshwater, and marine habitats. We investigated how habitat quality influenced the reproductive potential of mud crabs across 30 oyster reefs that were degraded to different extents. We further coupled this field survey with a laboratory experiment ...
Obstacle detection plays an important role in unmanned surface vehicles (USV). The USVs operate in highly diverse environments in which an obstacle may be a floating piece of wood, a scuba diver, a pier, or a part of a shoreline, which presents a significant challenge to continuous detection from images ...
Vibrio mimicus (V.mimicus) is a causative agent of ascites disease in aquatic animals. Our previous studies have demonstrated that the outer membrane protein U (OmpU) from V.mimicus is an immunoprotective antigen with six immunodominant linear B-cell epitopes. Although the N-terminus of OmpU contains ...
Vibrio parahaemolyticus, a Gram-negative motile bacterium that inhabits marine and estuarine environments throughout the world, is a major food-borne pathogen that causes life-threatening diseases in humans after the consumption of raw or undercooked seafood. The global occurrence of V. parahaemolyticus ...
Captive rearing programs (hatcheries) are often used in conservation and management efforts for at-risk salmonid fish populations. However, hatcheries typically rear juveniles in environments that contrast starkly with natural conditions, which may lead to phenotypic and/or genetic changes that adversely ...
A 2-year-old intact female miniature Pinscher weighing 1.7 kg with a body condition score of 2/5 was presented for acute vomiting, lethargy for 2 days, and large petechial skin lesions on the hip region including the tail. Acute pancreatitis was diagnosed by clinical signs, strong positive cPLI test, ...
Integrated Pest Management (IPM) is a leading complement and alternative to synthetic pesticides and a form of sustainable intensification with particular importance for tropical smallholders. Global pesticide use has grown over the past 20 years to 3.5 billion kg/year, amounting to a global market ...
Background Data derived from studies of fishers’ local ecological knowledge (LEK) can be invaluable to the proposal of new studies and more appropriate management strategies. This study analyzed the fisher’s LEK about trophic relationships of fishes in the southeastern Brazilian coast, comparing fishers’ ...
Aims To compare fluorescence in situ hybridization (FISH), immunohistochemistry (IHC) and quantitative real-time reverse transcription-PCR (qRT-PCR) assays for detection of ROS1 fusion in a large number of ROS1-positive lung adenocatcinoma (ADC) patients. Methods Using IHC analysis, sixty lung ADCs ...
The invention is a float for ensilation, comprising the following features: - one or more hulls with one or more closed tank rooms in said hull, - with an inlet to a grinder arranged for receiving and grinding fish and for feeding the ground fish down into one or more of the tank rooms. The ensilation ...
Bactericidal bacterial cells obtained by heating bacterial cells of coryneform bacteria or intestinal bacteria for 3 to 4 minutes at 90 to 120°C under a pH condition of 2 to 5, for example, or feed containing the bactericidal bacterial cells, is administered to mammals, birds, fish or crustaceans so ...
It is intended to provide solid feeds in an arbitrary size, in particular, fish feeds for large-size fishes such as tuna and a process for conveniently producing the same. Namely, a bound feed preferably having a diameter or a major axis of 5 cm or longer which is prepared by secondarily binding one ...
A coiled wave spring (9) includes a first and second coiled portions (91a, 91b). The first coiled portion (91a) has a plurality of first valley parts (911a) and a plurality of first peak parts (912a). The first valley parts (911a) and the first peak parts (912a) are alternately disposed in a circumferential ...
A gear attachment structure receives rotation of a handle assembly. The gear attachment structure includes a traverse cam shaft and a driven gear. The traverse cam shaft includes a shaft body, a gear support portion and a gear engaging portion. The gear support portion includes intersecting helical ...
