Alcohol use, aquatic injury, and unintentional drowning : A systematic literature review

2018

Issues Drowning is a global public health issue, and there is a strong association between alcohol and risk of drowning. No previous systematic review known to date has identified factors associated with alcohol use and engagement in aquatic activities resulting in injury or drowning (fatal and non‐fatal). Approach Literature published from inception until 31 January 2017 was reviewed. Included articles were divided into three categories: (i) prevalence and/or risk factors for alcohol‐related fatal and non‐fatal drowning and aquatic injury, (ii) understanding alcohol use and aquatic activities, and (iii) prevention strategies. Methodological quality of studies was assessed using National He…

Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron

2013

Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…

Diallyldimethylammonium Chloride (DADMAC) in Water Treated with Poly-Diallyldimethylammonium Chloride (PDADMAC) by Reversed-Phase Ion-Pair Chromatogr…

2023

Poly-diallyldimethylammonium (PDADMAC) chloride is a flocculant agent extensively used in water clarification treatments. Commercial polyelectrolyte formulations often contain residual monomer (DADMAC), reaction by-products and other reactants as contaminants that could potentially affect human health. In the present study, we optimized an analytical method based on reversed-phase ion-pair chromatography coupled with mass spectrometry for quantifying ultra-trace levels of DADMAC, without preliminary treatments, in drinking water distributed by the Palermo aqueduct. The method was validated in terms of accuracy (recovery between 80 to 120%), precision (RSD < 10%), linearity range (from 0.…

Waterfront e patrimonio militare: la base sottomarina di Saint-Nazaire

2012

Isolated from its harbour by the submarine base built during World War II, Saint-Nazaire has added to its development over the last two decades, without referring to major European models. An important arts and tourist center has been built around the port zone, close to the German submarine base. The converted military structure, which is situated in an impressive public space, has been endowed with a new sense of identity. It stands out as the main element in the urban regeneration process, focusing on the cultural and tourist character of the programme and aiming to reinforce the relationship between the city and its port.

Wyzwalanie dziecięcej aktywności matematycznej w trakcie rozwiązywania zadań

2018

Aktywność ucznia ma ogromne znaczenie w kształtowaniu i rozwijaniu abstrakcyjnych pojęć matematycznych. Jednak aktywność ta nie powinna ograniczać się jedynie do aktywności zewnętrznej, często jedynie pozornej, ale przede wszystkim powinna być to aktywność umysłowa ucznia. Zachowania i postawy specyficzne dla aktywności matematycznej można bowiem rozwijać u ucznia jedynie w toku jego aktywności poznawczej (intelektualnej). W opracowaniu podjęto próbę ukazania możliwości stymulowania i rozwijania oraz przejawy aktywności matematycznej uczniów w wieku wczesnoszkolnym w trakcie rozwiązywania zadań.

Saint-Dizier « la Tuilerie » (Haute-Marne) : trois sépultures d’élite du VIe siècle

2019

In 2002, excavations carried out by Marie-Cécile Truc (Inrap) at Saint-Dizier led to the discovery of four graves of exceptional wealth, containing a young woman, two men and a horse, dated to c. 525-550 AD. Dressed and adorned with numerous jewels, the young female was laid in a coffin upon which were placed vessels in glass, copper alloy goblet and ceramic. Each male had been buried in an excavated funerary chamber, built within an oak frame. They were laid in their coffins along with their personal clothing, including a ceremonial sword with two rings added to the pommel. The larger weapons (throwing axes, shields, lances and angons) as well as various utensils were placed either on the …

Sociedad, Estado y Derecho en la tradición de pensamiento dialéctico

2006

Esta investigación es un síntesis de los elementos más importantes que podemos encontrar en la llamada "tradición de la escuela dialéctica". Comenzamos con una explicación de "la filosofía del Derecho" de GWF Hegel y, a continuación exponemos la contraposición de puntos de vista de la visión del Estado por parte de K. Marx(Idealismo vs. Materialismo). En el segundo capítulo, el tema es la recepción que ha efectuado la marxista "Escuela de Frankfurt" de la política y las teorías sociológicas de M. Weber. Finalmente, exponemos de manera breve la teoría sobre el Estado moderno de J. Habermas, que trata de dar una solución a los problemas de la modernidad apuntados por los autores "Escuela de F…

Evaluation of lateral ankle instability with weight-bearing MRI. Preliminary Experience

2009

PURPOSE/INTRODUCTION: To assess the usefulness of weight-bearing examination of the ankle performed with a dedicated MRI scanner in the evaluation of patients with clinical evidence of lateral ankle instability. MATERIALS AND METHODS: We retrospectively evaluated ankle MR examinations of 18 patients, performed between September 2008 and January 2009. Spin echo T1W, Turbo Spine Echo T2W, 3D Steady-State (SSE) and Short Tau Inversion Recovery (STIR) images were acquired with a 0.2 T scanner (G-Scan, Esaote Spa, Genoa, Italy) in both weight-bearing position and normal conventional supine position. A dedicated extremities receiver coil was used. If present, signs of instability and ligament sig…

Weighted and unweighted distances based decision tree for ranking data

2018

Preference data represent a particular type of ranking data (widely used in sports, web search, social sciences), where a group of people gives their preferences over a set of alternatives. Within this framework, distance-based decision trees represent a non-parametric tool for identifying the profiles of subjects giving a similar ranking. This paper aims at detecting, in the framework of (complete and incomplete) ranking data, the impact of the differently structured weighted distances for building decision trees. The traditional metrics between rankings don’t take into account the importance of swapping elements similar among them (element weights) or elements belonging to the top (or to …
