Sensory methodology developed for the investigation of sciaccarello wine concept

2004

<p style="text-align: justify;">The aim of the present work was to underline the existence of a sensory space relevant to Sciaccarello wines. Twenty-eight wines were selected for viticultural and enological characteristics, using 1/2 Sciaccarello/Non- Sciaccarello ratio. Sensory analyses (orthonasal then overall perceptions) were performed with a panel composed of seventeen judges. All of the judges were experienced in Sciaccarello wines knowledge. Statistical treatment by PCA was first carried out to display the consensus between the assessors. ANOVA was performed to discriminate accurate and inaccurate examples of Sciaccarello wines. This study demonstrated the existence of the sens…

Effet de l'humidité sur la réponse à l'ammoniac de capteurs conductimétriques à base de matériaux moléculaires

2012

Many ammonia sensors are available but the consideration of the humidity effect is scarcely insured even by manufacturers. The aim of this thesis is to propose a conductimetric transducer capable tomeasure ammonia selectively, with enough accuracy for air quality control, in a variable humidity environment. To reach this goal, we used thin film resistors made of cobalt phthalocyanines as semiconductor. This study deals with thin films processing made by vacuum evaporation, solventcast and electrodeposition. Automated workbenches were developed to perform electrical measurements under argon and to study the response of sensors to dry or humid ammonia by meansof 1 min / 4 min-long exposure / …

Development of a microwave transduction gas sensor

2013

In this work, we have developed a new gas-sensing transduction based on the propagation of microwave inside a sensitive material to detect atmospheric pollutants at room temperature. First, we present a short overview of the main gas-sensing transduction in the litterature. These techniques operate in frequency ranges different from microwaves. The dielectric permittivity is the main physical parameter in the microwave transduction. The principle is based on the excitation of a sensitive material by a microwave electromagnetic field in a propagative structure. The reflected wave is specific to the excitation's frequency. It depends on the interaction between the sensitive material and the p…

Epistemic Modality Markers in European and American Law Journals

2013

Over the last decades the attention of scholars working in the filed of social sciences has been directed towards language variation, and discourse analysis has increasingly evolved as a valuable way of understanding the use of language in a variety of academic, institutional and professional settings (Clyne 1994; Flowerdew & Gotti 2006; Bhatia et al. 2008). According to the sociolinguist approach, genres become ‘dynamically rhetorical structures’ that can be manoeuvred according to the discipline’s norms, values and ideology, both historically and incrementally changing as disciplinary knowledge and genres required and created by discourse communities’ change (Bhatia 2004; Hyland 2004,…

Obesity and cardiovascular risk: a call for action from the European Society of Hypertension Working Group of Obesity, Diabetes and the High-risk Pat…

2018

: Obesity predisposes for atrial fibrillation, heart failure, sudden cardiac death, renal disease and ischemic stroke, which are the main causes of cardiovascular hospitalization and mortality. As obesity and the cardiovascular effects on the vessels and the heart start early in life, even from childhood, it is important for health policies to prevent obesity very early before the disease manifestation emerge. Key roles in the prevention are strategies to increase physical exercise, reduce body weight and to prevent or treat hypertension, lipids disorders and diabetes earlier and efficiently to prevent cardiovascular complications.

Asociacionismo Juvenil y ajuste en la adolescencia. Un análisis en la Comarca de la Safor.

2015

Esta tesis pretende comprobar si la pertenencia continuada a grupos asociativos durante la infancia-adolescencia, se relaciona con un mayor ajuste en la adolescencia, pudiendo convertirse en un factor de protección de conductas de riesgo como son las conductas adictivas y las conductas violentas. El marco teórico está basado en el estudio de la literatura científica que avalan la relación entre asociacionismo y participación juvenil y sus efectos en el ajuste psicosocial adolescentes y los beneficios para el bienestar y la calidad de vida. El asociacionismo es contemplando como una de las nuevas formas de participación y movilización social (Agudo, Martín y Tovar, 2011). Desde el modelo del…

The effects of technology-utilising rehabilitation on rehabilitees' physical activity: a prospective cohort study

2021

The aim of this study was to investigate the effects of technology-utilising rehabilitation on different intensities of physical activity (PA) and determine the explanatory factors of PA change. This was a prospective cohort study. Cardiac, musculoskeletal and vocational rehabilitees (N = 36) had 6 months of rehabilitation, which included guided training and counselling face-to-face as well as through distance technology. PA (total, light, moderate, vigorous) was measured by an activity tracker. Biopsychosocial questionnaires, waist circumference, PA measurements and m-coach activity were used to determine the factors that influence PA change. Technology-utilising rehabilitation improved li…

Fast blue B functionalized silica-polymer composite to evaluate 3,5-dihy-droxyhydrocinnamic acid as biomarker of gluten intake

2021

Celiac disease is an immune-mediated systemic disorder elicited by gluten and related prolamines in genetically susceptible individuals. The current treatment is a strict and lifelong gluten-free diet. However, compliance with the gluten-free diet is not always adequate and many food products contain low concentrations of gluten. The determination of dietary transgressions is a challenge for patients, physicians and dietitians. Alkylresorcinols (AR) have been proposed as sensitive and specific biomarkers of gluten consumption. In this work silica-polymer composites doped with fast blue B reagent (FB) have been used to estimate alkylresorcinols in biological samples. The proposed colorimetri…
