Mesoporous silica-based materials for use in biosensors
2012
Abstract There have been great advancements in the development of biosensors capable of characterizing and quantifying biomolecules. This article gives an overview of the formation, the properties and the electrochemical applications of ordered mesoporous silica-based materials in electrocatalysis, electrosorption, matrix immobilization, construction of systems for controlled release of active compounds, sensors, biosensors and immunosensors. We also present a comprehensive overview of current developments and key issues in the determination of some biological molecules with particular emphasis on the evaluation of models.
A Comparison Study of Modern Heuristics for Solving the Partitioning Problem in Distributed Virtual Environment Systems
2003
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environment (DVE) systems very common nowadays. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the servers in the system. In this paper, we present a comparison study of different modern heuristics for solving the partitioning problem in DVE systems, as an alternative to the ad-hoc heuristic proposed in the literature. Performance evaluation results show that som…
A bibliometric overview of the Journal of Business Research between 1973 and 2014
2015
Abstract The Journal of Business Research is a leading international journal in business research dating back to 1973. This study analyzes all the publications in the journal since its creation by using a bibliometric approach. The objective is to provide a complete overview of the main factors that affect the journal. This analysis includes key issues such as the publication and citation structure of the journal, the most cited articles, and the leading authors, institutions, and countries in the journal. Unsurprisingly, the USA is the leading region in the journal although a considerable dispersion exists, especially during the last years when European and Asian universities are taking a …
Dubbing dialogues… naturally: a pragmatic approach to the translation of transition markers in dubbing
2012
Although research in Audiovisual Translation is said to have come of age in the past decade, there are still several key issues that have not received the scholarly attention they deserve. In the case of dubbing, the study of the naturalness of dubbed dialogue is a case in point. The aim of the present article is to analyse the use of transition markers in dubbing in order to look precisely at the naturalness of dubbed dialogue while taking into account the dubbing constraints at play. This analysis is carried out by comparing the dubbed dialogue (English-Spanish) of a popular American sitcom to the non-translated but prefabricated dialogue of a Spanish sitcom and finally to spontaneous con…
The VET System, Its Subsystems and Their Links with the Labour Market: Strengths, Weaknesses and Challenges of VET in Spain
2019
This chapter provides the reader with the historical and political background to understand the rest of the book, and it also focuses on the key issues affecting VET in Spain in recent times while assessing the quality of VET rather positively. I explain the parallel development of three different subsystems and their approaches and efforts to reintegrate them. I also show conflicts over control upon VET governance and the role of national and regional governments as well as employers and union representatives in the design of qualifications. Transitions between education and employment, careers guidance and the connections of VET to social policies are also addressed.
A comparison study of evolutive algorithms for solving the partitioning problem in distributed virtual environment systems
2004
Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environment (DVE) systems very common nowadays.

Moral transgression, disease and holistic health in the Livingstonia Mission in late nineteenth and early twenttieth-century Malawi
2009
This article examines ideas of morality and health, and connections between moral transgression and disease in both Scottish missionary and Central African thought in the context of the Livingstonia Mission of the Presbyterian Free Church of Scotland in Malawi during the late nineteenth and early twentieth centuries.2 By concentrating on debates, conflicts and co-operation between missionaries and Africans over the key issues of beer drinking and sexual morality, this article explores the emergence of a new ‘moral hygiene’ among African Christian communities in Northern Malawi.<br><br>Este artículo analiza las ideas sobre moralidad y salud, así como las relaciones entre transgre…
Mesoporous silica materials for use in electrochemical immunosensing
2013
Abstract Silica-based electrochemical immunosensors recently gained much importance for detecting antigens and biomarkers responsible for cancer diagnosis. This review describes fabrication and chemical modification of the surfaces of mesoporous silica materials for biomedical and immunosensing applications. We also present a comprehensive overview of current developments and key issues in the determination of some biological molecules with particular emphasis on evaluating the models.
On the Characterization of Distributed Virtual Environment Systems
2003
Distributed Virtual Environment systems have experienced a spectacular growth last years. One of the key issues in the design of scalable and cost-effective DVE systems is the partitioning problem. This problem consists of efficiently assigning clients (3-D avatars) to the servers in the system, and some techniques have been already proposed for solving it.
Nuclear weak response from the combined study of beta-decay and charge-exchange reaction
2009
Studying the weak nuclear response, especially the Gamow-Teller (GT) transitions, of stable as well as unstable pf-shell nuclei, is one of the key issues in nuclear and astro-nuclear physics. We study the decay half-lives and the GT transitions starting from Tz = ±1 and ±2 mirror nuclei, respectively, by means of β decays and complementary hadronic (3 He , t) charge-exchange reactions. Under the assumption that isospin is a good quantum number, symmetry is expected for mirror nuclei and the GT transitions starting from the mirror nuclei. The half-lives and branching ratios and the measured strength distributions of GT transitions are compared and also combined for the understanding of the …
