HPLC/HRMS and GC/MS for Triacylglycerols Characterization of Tuna Fish Oils Obtained from Green Extraction
2023
Background: Fish oil is one of the most common lipidic substances that is consumed as a dietary supplement. The high omega-3 fatty acid content in fish oil is responsible for its numerous health benefits. Fish species such as mackerel, herring, tuna, and salmon are particularly rich in these lipids, which contain two essential omega-3 fatty acids, known as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Objectives: Due to the scarcity of information in the literature, this study aimed to conduct a qualitative and quantitative characterization of triglycerides (TAGs) in crude tuna fish oil using HPLC/HRMS. Fatty acid (FA) determination was also performed using GC/MS. The tuna fis…
Body weight and premature retirement : population-based evidence from Finland
2021
Background Health status is a principal determinant of labour market participation. In this study, we examined whether excess weight is associated with withdrawal from the labour market owing to premature retirement. Methods The analyses were based on nationally representative data from Finland over the period 2001–15 (N ∼ 2500). The longitudinal data included objective measures of body weight (i.e. body mass index and waist circumference) linked to register-based information on actual retirement age. The association between the body weight measures and premature retirement was modelled using cubic b-splines via logistic regression. The models accounted for other possible risk factors and p…

K°- K°, - D° and B° - B° oscillations in the Standard Model and beyond from unquenched Twisted Mass Lattice QCD
2013
El análisis del triángulo de unitariedad y la búsqueda de cotas restrictivas sobre las escala de nueva física requiere medidas precisas de las amplitudes de mezcla de las oscilaciones de mesones. El retículo proporciona una óptima herramienta no perturbativa para el cálculo de dichos elementos de matriz con incertidumbres del 1% y errores sistemáticos bajo control. La tesis se centra en el cálculo de los parámetros B, que controlan las oscilaciones de mesones, la masa del quark b y las constantes de desintegración fB y fBs a partir de QCD simulada en el retículo con fermiones Twisted Mass e incluyendo los efectos cuánticos de quarks dinámicos en el mar. A lo largo de esta tesis, a partir de…
El impacto social de la comunicación institucional del I+D+i en las universidades españolas
2022
Esta tesis tiene como objetivo principal estudiar la comprensión sobre la comunicación pública de la ciencia que se realiza en las universidades españolas, en concreto, desde los gabinetes de comunicación institucional y las Unidades de Cultura Científica y de Innovación (UCC+i). Una de las hipótesis principales de trabajo es que más allá de la divulgación científica que pueda realizar el propio personal investigador, el papel que desempeñan las instituciones en el ámbito de la comunicación pública del I+D+i puede contribuir a aumentar la visibilidad e impacto de los científicos. La investigación se presenta en dos presentaciones en congresos y cuatro estudios basados en metodologías cualit…
Social Media as Platform for Stimulating Urban Changes
2016
Images have always been an important part of city planning – current images of place, images with planned improvements, maps and sketches. Some time ago all that was a private property of stakeholders like planner and client. But nowadays this confidentiality rather much has vanished – no copyrights or competition is noteworthy. Plans do not have their privacy anymore. They are exposed even before they got implemented. This article will display why city planners share the images of their ideas, of their dreams in public (mostly in blogs and social networks) – why it is important for them and what kind of feedback they are waiting for. This article is based on case study where 12 respondents…
USUARIOS ACTIVOS Y PASIVOS. LA INTERACTIVIDAD DE LA AUDIENCIA EN LOS MEDIOS DIGITALES. EL CASO DE LA FÓRMULA 1 EN VALENCIA
2011
Los medios digitales se caracterizan por ofrecer multitud de herramientas interactivas a la audiencia. Sin embargo, es el usuario quien decide cuál es su grado de participación y qué uso hace de ellas. En este artículo analizamos el caso de la Fórmula 1 en los cibermedios valencianos y observamos dos tipos de usuarios: usuario activo y usuario pasivo. El usuario activo prefiere participar en las noticias más polémicas y escribe comentarios, mayoritariamente, cuando no está de acuerdo con el punto de vista de la información. Es decir, mantiene una actitud combativa. Por su parte, el usuario pasivo consume noticias que aborden temas más ligeros y cuando lee noticias politizadas, escoge el enc…
Behaviour of Extractives in Norway Spruce (Picea abies) Bark during Pile Storage
2022
The current practices regarding the procurement chain of forest industry sidestreams, such as conifer bark, do not always lead to optimal conditions for preserving individual chemical compounds. This study investigates the standard way of storing bark in large piles in an open area. We mainly focus on the degradation of the most essential hydrophilic and hydrophobic extractives and carbohydrates. First, two large 450 m3 piles of bark from Norway spruce (Picea abies) were formed, one of which was covered with snow. The degradation of the bark extractives was monitored for 24 weeks. Samples were taken from the middle, side and top of the pile. Each sample was extracted at 120 °C with both n-h…
Female reproductive factors are associated with objectively measured physical activity in middle-aged women
2017
Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women. In addition, we examined the association of physical activity with female reproductive factors at midlife. The study population consisted of 647 women …
Reliability and validation of the child eating behavior questionnaire in 3- to 6-year-old Spanish children
2022
IntroductionEating behavior is often established during the first years of life. Therefore, it is important to make a research on it to understand the relationships that children have with food and how this can contribute to prevent the development of childhood obesity. An appropriate assessment of eating behavior can be achieved using the “Child Eating Behavior Questionnaire” (CEBQ). This questionnaire has been validated in several populations and languages, but it has never been translated, adapted, and validated for Spanish children.AimTo evaluate the reliability and internal consistency of the CEBQ questionnaire, culturally adapted and translated into Spanish (Spain), in Spanish familie…
