Posterior moments and quantiles for the normal location model with Laplace prior

2021

We derive explicit expressions for arbitrary moments and quantiles of the posterior distribution of the location parameter η in the normal location model with Laplace prior, and use the results to approximate the posterior distribution of sums of independent copies of η.

Refractive analysis of the human cornea through propagated fields

2001

A new technique for analysing the optical quality of the human cornea is presented. Corneal maps are obtained through keratographies and then converted into phase maps. The propagated fields generated from this surface are plotted and studied. It is shown that any irregularity in the cornea affects the propagated field and the energy distribution at the focal plane. Simple applications are also indicated.

Results of isolated posterolateral corner reconstruction

2010

Abstract Background Isolated posterolateral corner (PLC) tears are relatively rare events. Various surgical techniques to treat posterolateral knee instability have been described; because surgical results are linked to cruciate reconstructions it has been difficult to date to define whether one surgical procedure has better prognosis than another. The goal of this study is to determine the clinical outcome of PLC reconstruction following fibular-based technique. Materials and methods We retrospectively evaluated a case series of patients who received isolated PLC reconstruction between March 2005 and January 2007. Ten patients were surgically treated for isolated injuries and were availabl…

Nordic contemporary art education and the environment: Constructing an epistemological platform for Art Education for Sustainable Development (AESD)

2012

How can art educators address questions of environmental sustainability, accepting to be ethically normative but avoiding becoming dogmatic? How can the complex ‘pool’ of knowledge generated in and through art education research become useful in working with these questions, which many of us find overwhelmingly difficult? AESD – Art Education for Sustainable Development – is a concept coined for this article with the intention of bringing environmental problems onto the agenda. In an attempt to provoke the necessary discussion about environmental sustainability in art education, the article examines selected texts from recent Nordic research in order to build an ‘epistemological platform’ t…

Improvement of dry eye symptoms with polyunsaturated fatty acids

2006

International audience; Purpose: Polyunsaturated fatty acids (PUFA) are involved in inflammatory pathways via prostaglandins. Conjunctival inflammation is a hallmark of all dry eye syndromes. We investigated the role of dietary n–6 and n–3 fatty acids in patients suffering from ocular dryness with peculiar attention to inflammatory markers. Methods: 70 patients presenting with mild to moderate dry eye syndromes were randomly assigned to Nutrilarm® or placebo pills, thrice a day for 6 months. Schirmer test, BUT, fluorescein and lissamin green stainings were performed at inclusion and after 1, 3 and 6 months. Impression cytology to evaluate MHCII antigens was harvested at D0, Month 3 and 6. T…

A taxonomic nightmare comes true: phylogeny and biogeography of glassworts (Salicornia L., Chenopodiaceae)

2007

In this study we analysed ETS sequence data of 164 accessions belonging to 31 taxa of Salicornia, a widespread, hygrohalophytic genus of succulent, annual herbs of Chenopodiaceae subfam. Salicornioideae, to investigate phylogenetic and biogeographical patterns and hypothesise about the processes that shaped them. Furthermore, our aim was to understand the reasons for the notorious taxonomic difficulties in Salicornia. Salicornia probably originated during the Miocene somewhere between the Mediterranean and Central Asia from within the perennial Sarcocornia and started to diversify during Late Pliocene/Early Pleistocene. The climatic deterioration and landscape-evolution caused by orogenetic…

Optimization of Polyphenols' Recovery from Purple Corn Cobs Assisted by Infrared Technology and Use of Extracted Anthocyanins as a Natural Colorant i…

2022

An ecofriendly extraction technology using infrared (IR) irradiation Ired-Irrad® was applied to purple corn cobs to enhance polyphenol recovery for the first time. The IR extraction efficiency was compared to that of the water bath (WB) method. Response surface methodology (RSM) using a central composite design was conducted to determine the effect of the experimental conditions (extraction time and treatment temperature) and their interactions on the total polyphenol and anthocyanin yields. Optimal extraction of total phenolic compounds (37 mg GAE/g DM) and total monomeric anthocyanins (14 mg C3G/g DM) were obtained at 63 °C for 77 min using IR as an extraction technique and water as a sol…

Acorn Ants May Create and Use Two Entrances to the Nest Cavity

2021

Many ant species construct large nests that are inhabited by numerous workers, but other species dwell in ready-for-use cavities and live in small colonies. Ants of the genus Temnothorax inhabit small cavities, e.g., in acorns, twigs, and under rocks. Although a preference for nest sites with a narrower entrance is known, recent studies have shown that they also use cavities with wider entrances and may modify the size of such entrances. As good cavities for nest sites are a limited resource, the possibility to modify a potential nest site, including a reduction in the size of the hole, should be a favorable matter for the ants. Through field and laboratory experiments, I studied the acorn …

Intermediate hosts of Angiostrongylus cantonensis in Tenerife, Spain.

2015

The nematode Angiostrongylus cantonensis is the causative agent of human angiostrongy- liasis, the main clinical manifestation of which is eosinophilic meningitis. Although this para- site has been found recently in its definitive rat host in Tenerife (Canary Islands, Spain), showing a widespread distribution over the north-east part of the island, there are no avail- able data regarding which snail and/or slug species are acting as intermediate hosts on this island. Consequently, the objective of this work was to determine the possible role of three mollusc species, Plutonia lamarckii , Cornu aspersum and Theba pisana , as intermediate hosts of A . cantonensis in Tenerife. Between 2011 and…
