The distribution, enrichment, accumulation, and potential ecological risk of copper (Cu) in the surface sediments of northern Kaohsiung Harbor, Taiwan were investigated. Sediment samples from 12 locations of northern Kaohsiung Harbor were collected and characterized for Cu, aluminum, water content, organic matter, total nitrogen, total phosphorous, total grease and grain size. Results showed th...

A rudimentary predator-prey model is considered that is stoichometric, in that the nutrient content of the producer species affects the ability of the consumer to produce biomass. We show that the model supports biologically important dynamical properties that differ from the corresponding non-stoichiometric model. Specifically, under the assumption of Holling II-type functional response, for a...

Methanosaeta harundinacea and Methanosarcina barkeri, known as classic acetoclastic methanogens, are capable of directly accepting electrons from Geobacter metallireducens for the reduction of carbon dioxide to methane, having been revealed as direct interspecies electron transfer (DIET) in the laboratory co-cultures. However, whether their co-occurrences are ubiquitous in the iron (III)-reduci...

We demonstrate a metadata enrichment system for the Europeana digital library. The system allows different institutions which provide to Europeana pointers (in the form of metadata records MRs) to their content to enrich their MRs by classifying them under a classification scheme of their choice, and to extract/highlight entities of significant interest within the MRs themselves. The use of a s...

LODr is a personal application providing semantic-enrichment features for existing tagged content from various popular Web 2.0 services, such as Flickr, del.icio.us or Twitter. By allowing people to re-tag their content with URIs, rather than simple keywords, it weaves their social data to the Semantic Web. In this paper, we detail the principes of this application, the underlying models, its d...

Many digital sound archives suffer from problems concerning on-line access: sound materials are often held separately from other related media, they are not easily browsed and little opportunity to search the actual audio content of the material is provided. The EASAIER project aims to alleviate these problems, offering a number of solutions to support sound archive managers and users. EASAIER ...

An innovative single-stranded DNA (ssDNA) library preparation method has sparked great interest among ancient DNA (aDNA) researchers, especially after reports of endogenous DNA content increases >20-fold in some samples. To investigate the behavior of this method, we generated ssDNA and conventional double-stranded DNA (dsDNA) libraries from 23 ancient and historic plant and animal specimens. W...

BACKGROUND The ability to identify low-level somatic DNA mutations and minority alleles within an excess wild-type sample is becoming essential for characterizing early and posttreatment tumor status in cancer patients. Over the past 2 decades, much research has focused on improving the selectivity of PCR-based technologies for enhancing the detection of minority (mutant) alleles in clinical sa...

In this study, the effects of hydrogen and hydroxygen additions and oxygen enrichment on the emission characteristics of a gasoline engine (EF7) were investigated and compared with each other. The simulation was launched by GT-Power at different engine speeds with 5 % to 15 % volume fractions for both of oxygen and hydrogen enrichment and 4.5 % to 9 % volume fractions of hydroxygen addition in ...

Background: Developing and promoting empathy between couples can assist them in dealing with destructive communication patterns, increasing their satisfaction through effective dialogue and conversation, and, as a result, creating a safe place to meet emotional needs. The present study aimed to determine the effectiveness of Olson’s enrichment training program and Johnson’s relationship enrichm...
