Geolinguistic Regions and Diasporas in the Age of Satellite Television
(SAGE Publications, 2007)
Studies of the globalization processes in the communications media have frequently emphasized the planetary-scale diffusion of the dominant cultural and linguistic models. This is undoubtedly a clearly observable tendency ...
Validation of a screening questionnaire for hip and knee osteoarthritis in old people
(BioMed Central, 2007-08-23)
Background: To develop a sensitive and specific screening tool for knee and hip osteoarthritis in the general population of elderly people.
Methods: The Knee and Hip OsteoArthritis Screening Questionnaire (KHOA- SQ) was ...
Oscillatory behavior in linear difference equations under unmodeled dynamics and parametrical errors
(Hindawi Publishing Corporation, 2007)
This paper investigates the presence of oscillating solutions in time-varying difference equations even in the case when there exist parametrical errors (i.e., errors in the sequences defining their coefficients) and/or ...
Rapid determination of total CLA concentration in beef fat
(Agricultural Institute of Canada, 2007-06)
[EN]Conjugated linoleic acid (CLA) has many potential healthful properties, and beef is naturally enriched with CLA. Simple and rapid methods to measure total CLA were investigated to enable sorting of beef carcasses with ...
On the properties of reachability, observability, controllability, and constructibility of discrete-time positive time-invariant linear systems with aperiodic choice of the sampling instants
(Hindawi Publishing Corporation, 2007)
This paper investigates the properties of reachability, observability, controllability, and constructibility of positive discrete-time linear time-invariant dynamic systems when the sampling instants are chosen aperiodically. ...
Marked decrease in the incidence and prevalence of hepatitis A in the Basque Country, Spain, 1986–2004
(Cambridge University Press, 2007-04)
The aim of this study was to determine changes in the epidemiology of hepatitis A virus (HAV) infection in the Basque Country, Spain, and to evaluate their implications for vaccination strategies. A total of 1356 persons ...
About K-Positivity Properties of Time-Invariant Linear Systems Subject to Point Delays
(Hindawi Publishing Corporation, 2007)
This paper discusses nonnegativity and positivity concepts and related properties for the state and output trajectory solutions of dynamic linear time-invariant systems described by functional differential equations subject ...
Functional analysis of cancer-associated EGFR mutants using a cellular assay with YFP-tagged EGFR intracellular domain
(BioMed Central, 2007-09)
Background: The presence of EGFR kinase domain mutations in a subset of NSCLC patients correlates with the response to treatment with the EGFR tyrosine kinase inhibitors gefitinib and erlotinib. Although most EGFR mutations ...
Molecular Components and Functions of the Endocannabinoid System in Mouse Prefrontal Cortex
(Public Library of Science, 2007-08-08)
Background. Cannabinoids have deleterious effects on prefrontal cortex (PFC)-mediated functions and multiple evidences link the endogenous cannabinoid (endocannabinoid) system, cannabis use and schizophrenia, a disease in ...
Institutional designs to face the dark side of total allowable catches
(Oxford Journals, 2007)
Setting total allowable catches (TACs) is an endogenous process in which different agents and institutions, often with conflicting interests and opportunistic behaviour, try to influence policy-makers. Such policy-makers, ...
