Summary The deposition of elemental sulfur as a solid phase results in plugging the pore space available for gas flow and reduces the reservoir productivity. Elemental sulfur also can be deposited as a liquid phase if the reservoir temperature is greater than 115°C. The liquid sulfur restricts the ...
Mature specimens of Clarias batrachus were exposed to Ganga river water in Kanpur containing environment for 115 days duration, over which the observations were recorded on 30th, 60th, 90th, 105th and finally 115th day. The fish was maintained unfed. An average increase of 4.2 ± 0.35 cm in length and ...
One of the key factors to enhance the level of Chinese rural logistics is to evaluate and improve the operational efficiency of rural logistics service providers' performance. By using the data envelopment analysis (DEA) method, the paper takes thirty Chinese rural logistics service providers out-output ...
The following topics are dealt with: nano mechatronics; humanoid robot; bio-inspired underwater robots; intelligent control; biomedical robots; sensor; fault diagnosis; modeling and simulation; robust controller design; robot vision; robot control; robot design and analysis; mobile robot navigation; ...
Emotion plays an important role in human computer interaction to give a human like feel. To acknowledge the importance of emotions in an artificial agent, we propose a domain independent emotion mining model (EmoXract) which extracts emotions from an unstructured data. The emotion is extracted at sentence ...
Due to the complexity of software systems, defects are inevitable. Understanding the types of defects could help developers to adopt measures in current and future software releases. In practice, developers often categorize defects into various types. One common categorization is based on fault triggers ...
This descriptive study determined the profile of the people living near Estero de Paco in Manila. It also determined their attitudes and perceptions towards the use and purpose of the estuary and the technology management practices employed to rehabilitate it. It was revealed that most of the respondents ...
An initiative in Brazil teaches computing to young people alongside their parents in family workshops through game programming using Scratch - with benefits that reach beyond the classroom and into the community.
Adverse birth outcomes including preterm birth (PTB: <37 weeks gestation) and low birth weight (LBW: <2500 g) can result in severe infant morbidity and mortality. In the United States, there are racial and ethnic differences in the prevalence of PTB and LBW. We investigated the association between ...
Big Data analytics has become a powerful tool in monitoring invasive species, with ecologists saying that with the problem of invasive species being on such a large scale, it is essential to analyse lots of data through studying several ecosystems. Supercomputers can help conduct analysis of the terabytes ...
Surface water is a critical resource in semiarid West-African regions that are frequently exposed to droughts. Natural and artificial wetlands are of high importance for different livelihoods, particularly during the dry season, from October/November until May. However, wetlands largely go unmonitored. ...
The marine biodiversity of Gabon, West Africa has not been well studied and is largely unknown. Our examination of marine communities associated with oil platforms in Gabon is the first scientific investigation of these structures and highlights the unique ecosystems associated with them. A number of ...
Background Coilia nasus (Japanese grenadier anchovy) undergoes spawning migration from the ocean to fresh water inland. Previous studies have suggested that anadromous fish use olfactory cues to perform successful migration to spawn. However, limited genomic information is available for C. nasus. To ...
Anthropogenic impacts are increasingly affecting the world's oceans. Networks of marine protected areas (MPAs) provide an option for increasing the ecological and economic benefits often provided by single MPAs. It is vital to empirically assess the effects of MPA networks and to prioritize the monitoring ...
Traditional 3D visual simulation of flexible fishing net has the problems of complicated computation and no collision detection studied. In this paper, a 3D visual simulation method is researched in order to simulate the dynamic deformation of the flexible fishing net. To solve the computational inefficiency ...
Escherichia coli is a widespread bacterium encompassing a variety of strains, ranging from highly pathogenic strains, causing worldwide outbreaks of severe diseases to avirulent, well characterized safe laboratory strains. This study evaluated the prevalence and antibiogram profiles of E. coli pathotypes ...
We assessed the occurrence of Vibrio pathogens in the final effluents of five wastewater treatment plants (WWTPs) located in Amathole and Chris Hani District Municipalities in South Africa over a 12 months period between September 2012 and August 2013 using standard membrane filtration technique followed ...
The interaction between volatile and non-volatile, e.g. proteinaceous, components of pheromone and other semiochemical-based signalling systems presents a daunting set of problems for exploitation in the management of vertebrates, good or bad. Aggravating this is the complexity of the mixtures involved ...
Background The sequencing, de novo assembly and annotation of transcriptome datasets generated with next generation sequencing (NGS) has enabled biologists to answer genomic questions in non-model species with unprecedented ease. Reliable and accurate de novo assembly and annotation of transcriptomes, ...
