Research on Optimal Design of Rubber Isolator Used in Propulsion System

The paper researches and designs a kind of rubber isolator to reduce the acting force of the power transmission system to the ship hull. And it analyzes the working principle of the propulsion system, and builds the dynamics analysis model to obtain the initial parameters of the power transmission system. ...

Optimal layout and safety development of marine industry in China

Existing research on layout of the marine industry is still at a scattered exploration stage, and results calculated with a relatively mature grey correlation method indicate that China is divided into three major industrial correlation regions with Shandong, Shanghai and Hainan as the core respectively ...

Correlation analysis of natural environment test and laboratory accelerated test

There is a growing concern about correlation analysis of natural environment test and laboratory accelerated test, especially test about corrosion of metal, nonmetal and coatings. This paper will concentrate on correlation analysis from simulation ability, accelerating ability and reproducibility. As ...

Approaches for CO2 Capture and Sequestration Inspired by Biological Systems

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 180718, “Approaches for CO2 Capture and Sequestration Inspired by Biological Systems,” by Z. Ouled Ameur and S. Gupta, Cenovus Energy, and Hector De La Hoz Siegler, University of Calgary, prepared for the ...

A new approach to use dual-polarized SAR imagery for the detection of bivalve beds on exposed intertidal flats

The most common polarimetric decompositions can only be computed for fully polarimetric data at the cost of reduced spatial resolution and areal coverage. In this paper, we analyze the potential of dual-pol SAR imagery for the monitoring of bivalve beds on intertidal flats. The normalized Kennaugh elements, ...

Modeling the habitat suitability index of skipjack tuna (katsuwonus pelamis) in the western and central pacific ocean

Skipjack tuna (Katsuwonus pelamis) is the major target species in Taiwan pelagic purse-seine in the western and central Pacific Ocean with approximate 90% of catch rate in all harvested species. This study attempts to identify the habitat suitability index (HSI) for skipjack tuna in the western and ...

Building Young Minds Brick by Brick

For working parents, there's an intensity to Thursdays that can border on the overwhelming. Status reports are due, kids have tests to prepare for, and meetings pile up from projects unfinished from the week, making my Outlook calendar look like one of Piet Mondrian's more colorful works. Careful observers ...

Consumption patterns of meat, poultry, and fish after disaggregation of mixed dishes: secondary analysis of the Australian National Nutrition and Physical Activity Survey ...

Background With the increased consumption of mixed dishes, the need for more precise quantitative data on individual food components is becoming more important. This paper aims to examine the consumption of meat, poultry, and fish before and after disaggregation of mixed dishes, and its contribution ...

Determination of Trophic Structure in Selected Freshwater Ecosystems by using Stable Isotope Analysis

Stable isotope analysis has been used extensively to establish trophic relationships in many ecosystems. Present study utilised stable isotope signatures of carbon and nitrogen to identify trophic structure of aquatic food web in river and rice field ecosystems in Perak, northern peninsular Malaysia. ...

Correlations of Biomarkers and Self-Reported Seafood Consumption among Pregnant and Non-Pregnant Women in Southeastern Louisiana after the Gulf Oil Spill: The GROWH Study

Seafood contains health-promoting fatty acids, but is often contaminated with mercury (Hg), complicating recommendations and choices around fish consumption during pregnancy. Self-reported diet may be subject to inaccuracy and this inaccuracy could differ according to pregnancy status. We investigated ...

Conservation and divergence of mitochondrial apoptosis pathway in the Pacific oyster, Crassostrea gigas

Apoptosis is considered a crucial part of the host defense system in oysters according to previous reports; however, the exact process by which this occurs remains unclear. Besides, mitochondrial apoptosis is the primary method of apoptosis in vertebrate cells, but has been poorly studied in invertebrates ...

Combination of t(4;14), del(17p13), del(1p32) and 1q21 gain FISH probes identifies clonal heterogeneity and enhances the detection of adverse cytogenetic profiles in 233 ...

Background Our aim was to set the FISH combination of del(17p13), t(4;14), 1q21 gain and del(1p32), four adverse cytogenetic factors rarely evaluated together, and compare our technical thresholds with those defined in the literature. Methods Two hundred thirty-three patients with MM at diagnosis ...

Assessment of critical steps of a GC/MS based indirect analytical method for the determination of fatty acid esters of monochloropropanediols (MCPDEs) and of glycidol (GE...

Fatty acid esters of 2- and 3-chloropropanediol (MCPDEs) and fatty acid esters of glycidol (GEs) are commonly monitored in edible fats and oils. A recommendation issued by the European Commission emphasizes the need of generating data on the occurrence of these substances in a broad range of different ...

Acoustic target strength (TS) of argentine anchovy (Engraulis anchoita): The nighttime scattering layer

Engraulis anchoita is a physostomous fish with a dual chambered swim bladder (sb). In situ target strength (TS) measurements on this species are only possible at night, when anchovies disperse and form a scattering layer near the sea surface. A survey data series comprising more than50000 single target ...

Effect of environmental parameters on long range Wi-Fi connectivity

Typically, marine fishermen take 5–7 days for a single fishing trip. They travel 40–120 km away from the shore. There is no viable communication technology available currently to keep them connected to the shore while they are gone. We have successfully developed and prototyped a marine communication ...

The integrated loading and unloading quay crane scheduling problem by AFSA-GA algorithm

The Integrated loading and unloading quay cranes (QCs) scheduling problem is to minimize the QC number for loading and unloading operations in same ship-bay. The AFSA-GA algorithm is proposed to solve the mixed integer programming model., which take advantage of the strong local search ability of GA ...

Adaptive step mechanism in Glowworm Swarm Optimization

Glowworm Swarm Optimization Algorithm (GSO) is one of new swarm intelligence optimization algorithms in recent years. Its main idea comes from the cooperative behavior source among individuals during the process of courtship and foraging. In this paper, in order to improve convergence speed in the late ...

An efficient feature selection using artificial fish swarm optimization and svm classifier

The medical datasets have many features if the features have a tendency of mutation then the risk of disease increases which makes difficult to provide a diagnosis of disease. In the dataset, every feature is a contributor for prediction accuracy, the selection of significant features from the dataset ...

Archimedes screw generators for sustainable energy development

The Archimedes screw has been used as a pump since antiquity and has more recently been used to generate hydroelectric power in plants up to about 200 kW. Archimedes screw generators (ASGs) operate as run-of-river, have low environmental impact and are a uniquely efficient means of generating hydroelectricity ...

Developing the academic-industrial partnership through student research and projects: Case studies from Iceland

The authors have all worked in industry before they joined academia. They present their views and observations on establishing joint academic-industrial projects, based on their former experience in industry and from the viewpoint of the university. Different forms of collaboration are discussed, as ...
