A delphi study on collaborative learning in distance education: the faculty perspective
(Wiley-Blackwell, 2010-09-21)This paper focuses on the factors that influence collaborative learning in distance education. Distance education has been around for many years and the use of collaborative learning techniques in distance education is ... -
A depth map post-processing approach based on adaptive random walk with restart
(Institute of Electrical and Electronics Engineers (IEEE), 2016-01-01)Accurate depth estimation is still an important challenge after a decade, particularly from stereo images. The accuracy comes from a good depth level and preserved structure. For this purpose, a depth post-processing ... -
A descriptive survey study of violence management and priorities among psychiatric staff in mental health services, across seventeen european countries
(Springer Nature, 2017-01-19)Background: In mental health services what is commonplace across international frontiers is that to prevent aggressive patients from harming themselves, other patients or staff, coercive measures and foremost, violence ... -
A detailed appraisal of mesocolic lymphangiology - an immunohistochemical and stereological analysis
(Wiley-Blackwell, 2014-07-19)Inadequate resection of the adjoining mesentery is associated with adverse outcome for colon cancer. Disruption of the integrity of the mesenteric lymphatic package has been implicated in this, though not proven. Recent ... -
A detailed assessment of the wave energy resource at the atlantic marine energy test site
(MDPI AG, 2016-11-18)Wave characteristic assessments of wave energy test sites provide a greater understanding of prevailing wave conditions and are therefore extremely important to both wave energy test site operators and clients as they can ... -
A detailed evaluation of the current renal response criteria in al amyloidosis: is it time for a revision?
(Ferrata Storti Foundation (Haematologica), 2013-05-31)Organ response correlates with overall survival in patients with immunoglobulin light chain amyloidosis and is the goal of treatment. This study evaluates the current renal response criteria and their ability to predict ... -
A differential interplay between the expression of th1/th2/treg related cytokine genes in teladorsagia circumcincta infected drb1*1101 carrier lambs
(Springer Nature, 2011-01-01)Substantial debate exists on whether the immune response between sheep resistant and susceptible to gastrointestinal nematodes can be differentiated into a Th1 and Th2 phenotype. The present study addresses the hypothesis ... -
A dileucine in the protease of botulinum toxin a underlies its long-lived neuroparalysis
(American Society for Biochemistry & Molecular Biology (ASBMB), 2010-12-07)Blockade of neurotransmitter release by botulinum neurotoxin type A (BoNT(A)) underlies the severe neuroparalytic symptoms of human botulism, which can last a few years. The structural basis for this remarkable persistence ... -
A distinct profile of tryptophan metabolism along the kynurenine pathway downstream of toll-like receptor activation in irritable bowel syndrome
(Frontiers Media SA, 2012-01-01)Irritable bowel syndrome (IBS), a disorder of the brain-gut axis, is characterised by the absence of reliable biological markers. Tryptophan is an essential amino acid that serves as a precursor to serotonin but which can ... -
A double segment periodicity underlies segment generation in centipede development
(Elsevier BV, 2004-07-01)The number of leg-bearing segments in centipedes varies extensively, between 15 and 191, and yet it is always odd [1, 2]. This suggests that segment generation in centipedes involves a stage with double segment periodicity ... -
A family of [ni8] cages templated by μ6-peroxide from dioxygen activation
(Royal Society of Chemistry (RSC), 2014-01-01)A family of exceptionally thermally stable [Ni-8] cages is reported, each being templated by a rare eta(3):eta(3):mu(6)-O-2(2-) species produced by dioxygen activation, where the reducing agent for the O-2 reduction appears ... -
A family of symmetric designs
(Elsevier BV, 1995-11-01)An embedding theorem for certain quasi-residual designs is proved and is used to construct a series of symmetric designs with upsilon a = (1 + 16 + ... + 16(m))9 + 16(m+1), k = (1 + 16 + ... + 16(m))9, and lambda =(1 + 16 ... -
A field deployable method for a rapid screening analysis of inorganic arsenic in seaweed
(Springer Nature, 2017-03-18)Inorganic arsenic (iAs) in 13 store-bought edible seaweed samples and 34 dried kelp (Laminaria digitata) samples was determined by a newly developed, field-deployable method (FDM) with the aid of a field test kit for arsenic ... -
A finite element study of microstructure-sensitive plasticity and crack nucleation in fretting

A first test of the implicit relational assessment procedure as a measure of self-esteem: irish prisoner groups and university students
(Springer Nature, 2009-07-01)The study examined the Implicit Relational Assessment Procedure's (IRAP) validity as a computerized response-latency-based measure of implicit self-esteem. University undergraduates and 2 sets of convicted prisoners ... -
A fixed point theorem for condensing operators and applications to hammerstein integral equations in banach spaces
(Elsevier BV, 1995-11-01)We prove a fixed point theorem of Purl Pera type for condensing operators. This will then be used to establish the existence of solutions to certain integral equations of Hammerstein type in Banach spaces. -

A flexible r package for nonnegative matrix factorization
(Springer Nature, 2010-01-01)Background: Nonnegative Matrix Factorization ( NMF) is an unsupervised learning technique that has been applied successfully in several fields, including signal processing, face recognition and text mining. Recent applications ... -
A fluid-structure interaction model to characterize bone cell stimulation in parallel-plate flow chamber systems
(The Royal Society, 2013-01-30)Bone continuously adapts its internal structure to accommodate the functional demands of its mechanical environment and strain-induced flow of interstitial fluid is believed to be the primary mediator of mechanical stimuli ... -
