A whale became stranded in a well-known river in the east of England recently but all efforts to save it failed and the animal died. But this was not the northern bottlenose whale that entered the river Thames to a mass of publicity, but a young sperm whale that became trapped on sandbanks in the river Humber, 200 km further north, which attracted little media attention. The contrast serves as ...

Large population sizes and global distributions generally associate with high mitochondrial DNA control region (CR) diversity. The sperm whale (Physeter macrocephalus) is an exception, showing low CR diversity relative to other cetaceans; however, diversity levels throughout the remainder of the sperm whale mitogenome are unknown. We sequenced 20 mitogenomes from 17 sperm whales representative ...

The overall goal of this project was to improve our understanding of beaked whale distribution and foraging behavior and to describe inter-specific differences. We investigated spatio-temporal patterns for Cuvier’s beaked whale and a beaked whale producing echolocation signal type BW43 in the Southern California Bight using passive acoustic encounters, comparing data gathered from line transect...

In the sperm whale (Physeter macrocephalus) two different repeat types (A and B) of the common cetacean DNA satellite were identified. The evolution of each group of repeats appears to be independent from that of the other. The sequence similarity between the two groups is less than the similarity between group A and repeats of the satellite in related whale species. The systematic relationship...

Whale sharks attract large numbers of tourists, divers and snorkelers each year to South Ari Atoll in the Republic of Maldives. Yet without information regarding the use and economic extent of the attraction, it is difficult to prioritize conservation or implement effective management plans. We used empirical recreational data and generalized mixed statistical models to conduct the first econom...

Purpose: The development of metaheuristic algorithms has increased by researchers to use them extensively in the field business, science, and engineering. One common optimization is called Grey Wolf Optimization (GWO). algorithm works based on imitation wolves' searching process attacking grey wolves. main purpose this paper overcome GWO problem which trapping into local optima. Design or Metho...

Optimizing naval aircraft deck sortie scheduling is important for improving the efficiency of groups. It also an link in realizing automated carriers. Firstly, a single-aircraft surface transit path library was constructed. This paper used improved A* algorithm and optimal control planning to construct between parking position take-off position, or warmable non-warmable positions. Secondly, mat...

Successful privatization in other sectors leads to a restructuring the power sector. The same practice has been adopted electrical industry with deregulated electricity market (EM). This enables competition among generating companies (Genco’s) for maximizing their profit and it plays central role. With this aim, each Genco gives higher bid that may result risk of losing opportunity get selected...

in this paper, we present a binary-linear optimization model to prevent the spread of an infectious disease in a community. the model is based on the remotion of some connections in a contact network in order to separate infected nodes from the others. by using this model we nd an exact optimal solution and determine not only the minimum number of deleted links but also their exact positions. ...

introduction: optimized production and quality control of 68ga-dotatate as an efficient and preferable pet radiotracer for somatostatin receptor imaging in neuroendocrine tumors is of great interest. in this study effort has been made to present a fast, efficient, cost-effective and facile protocol for 68ga-dotatate productions for clinical trials. methods:68ga-dotatatewas prepared using genera...
