S. haematobium as a Common Cause of Genital Morbidity in Girls: A Cross-sectional Study of Children in South Africa

2013

Background Schistosoma (S.) haematobium infection is a common cause of genital morbidity in adult women. Ova in the genital mucosal lining may cause lesions, bleeding, pain, discharge, and the damaged surfaces may pose a risk for HIV. In a heterogeneous schistosomiasis endemic area in South Africa, we sought to investigate if young girls had genital symptoms and if this was associated with urinary S. haematobium. Methodology In a cross-sectional study of 18 randomly chosen primary schools, we included 1057 schoolgirls between the age of 10 and 12 years. We interviewed assenting girls, whose parents had consented to their participation and examined three urines from each of them for schistos…

Publicidad y cáncer en la prensa escrita (1903-1912)

2020

El cáncer es una de las enfermedades más graves de nuestro tiempo debido a su elevada prevalencia, morbilidad y mortalidad, lo que la ha convertido en contenido habitual de la información periodística a lo largo de la historia. En este artículo se pretende analizar cómo fueron los anuncios publicitarios relativos a los productos, establecimientos y servicios que se ofertaban a principios del siglo XX en España, en relación con la enfermedad del cáncer, así como realizar una aproximación a la realidad social, cultural y educativa en el periodo de tiempo estudiado. A partir de la hemeroteca digital de los periódicos ABC y La Vanguardia, se seleccionaron todos los anuncios publicitarios que ap…

Optimal Tree Decompositions Revisited: A Simpler Linear-Time FPT Algorithm

2020

In 1996, Bodlaender showed the celebrated result that an optimal tree decomposition of a graph of bounded treewidth can be found in linear time. The algorithm is based on an algorithm of Bodlaender and Kloks that computes an optimal tree decomposition given a non-optimal tree decomposition of bounded width. Both algorithms, in particular the second, are hardly accessible. We present the second algorithm in a much simpler way in this paper and refer to an extended version for the first. In our description of the second algorithm, we start by explaining how all tree decompositions of subtrees defined by the nodes of the given tree decomposition can be enumerated. We group tree decompositions …

Epizootiology of protozoans in farmed salmonids at northern latitudes

1997

Abstract Protozoan ectoparasites were examined in a northern salmonid fish farm over a 10-year period, June 1984–May 1994, by the same researcher, with similar catching and sampling procedures throughout. Husbandry procedures remained constant during the study, e.g., fingerlings were kept in steel tanks and yearlings in both steel tanks and earth ponds. Ichthyobodo necator, Chilodonella hexasticha and Ichthyophthirius multifilurs infections were treated with formalin, salt and malachite green-formalin baths, respectively, whenever any parasites were found. Altogether 10 790 randomly sampled salmon (Salmo solar), sea trout (S. trutta m. trutta) and brown trout (S. trutta m. lacustris) were s…

Ferromagnetic copper(II)–copper(II) interaction in a single chlorido and dicyanamido bridged mixed–valence copper(I/II) 2D polymer generated by in si…

2015

A mixed-valence 2-D Cu(I/II) complex, [{Cu(II)(dmen)(μ-Cl)(μ1,5-dca)}{Cu(I)(μ1,5-dca)}]n (1) (dmen = N,N-dimethylethylenediamine, dca = dicyanamide = [N(CN)2]−), has been synthesized by in situ partial reduction of Cu(II) to Cu(I) using benzoin (2-hydroxy-1,2-di(phenyl)ethanone) as reductant. Complex 1 was characterized by spectroscopic techniques, single crystal X-ray diffraction, and low temperature magnetic measurements. Structural investigation reveals that 1 represents a mixed-valence 2-D coordination polymer formed by parallel 1-D [Cu(II)(dmen)(Cl)Cu(I)(μ1,5-dca)2]n chains running along the b axis, where chloride bridges Cu(II) ions of adjacent polymers through long connections (2.840…

Two-generation cardiovascular disease prevalence in familial hypercholesterolemia

2016

Bibliometric analysis of the scientific production of literature on peri-implant diseases in the Web of Science.

2021

Background The exponential increase in implant placement worldwide and the high prevalence of its associated pathologies have prompted an increasing contribution by the scientific community to the number of publications related to peri-implant pathologies. Purpose The objective of this work is to carry out a bibliometric analysis of scientific production on peri-implant diseases. Materials and methods The search strategy included titles, keywords, and abstracts based on the term peri-implantitis and all the possible combinations existing in Science Citation Index Expanded (SCIE) of the main collection of Web of Science. Two limits were established: the document typology was limited to Artic…

Reduction of UML Class Diagrams

2002

One and the same “real world” can be modeled by different UML class diagrams, which in such a case can be considered “intuitively equivalent”. A formalization of this “intuitive equivalence” of class diagrams is proposed. An algorithm is constructed that for two class diagrams determines if they model the same “real world”. This algorithm can be used in CASE tools to compare alternative models of a system, and for diagram “compression” to facilitate understanding of large diagrams.

Old concepts, new ideas: approaches to translation shifts

2009

This paper traces the development of the translation shift concept from its origins in the linguistics-oriented era of translation studies to its current revival in computer-based approaches: after a presentation of the traditional approaches by John C. Catford, Jean-Paul Vinay and Jean Darbelnet, Eugene A. Nida, and Kitty van Leuven-Zwart, several recent studies that have integrated the concept of translation shifts are introduced and discussed. This comparison of old and new approaches reveals that the attitudes towards shifts have changed from mildly prescriptive to neutrally descriptive. The paper concludes with a general evaluation of the place of linguistic approaches in translation s…
