Synergies in Design and Health. The role of architects and urban health planners in tackling key contemporary public health challenges
2020
Background and aim: Important public health improvements have been achieved over the past decades, but new challenges are emerging and progress cannot be taken for granted. Urban settlements host most of the global population, but they are also sources of several threats. The aim of the paper is to investigate the role of architects and planners in contributing to overcome these critical health challenges and propose strategic actions for collaboration with the public health workforce. Methods: Taking global trends and public health challenges as starting point, a scoping literature review has been conducted to illustrate the possible synergies that architecture and public health workforce …

Measurement Properties of Smartphone Approaches to Assess Physical Activity in Healthy Young People: Systematic Review
2022
Background Physical inactivity is a preventable risk factor for several chronic diseases and one of the driving forces behind the growing global burden of disease. Recent evidence has shown that interventions using mobile smartphone apps can promote a significant increase in physical activity (PA) levels. However, the accuracy and reliability of using apps is unknown. Objective The aim of our review was to determine the accuracy and reliability of using mobile apps to measure PA levels in young people. We conducted a systematic review guided by PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Methods Studies published from 2007 to 2020 were sourced from 8 databa…
Children's nutritional status and parental educational styles: an experts appreciation
2013
Antecedentes: la obesidad infantil ha sido estudiada de manera amplia en aspectos de diagnóstico y tratamiento fundamentalmente, pero aquellos referidos a la prevención desde factores familiares, no genéticos, han estado muy ausentes del foco de las investigaciones en salud y nutrición pública. Objetivo: explorar las apreciaciones de los profesionales de la nutrición sobre las posibles relaciones entre el tipo de familia, el estado nutricional infantil y los estilos educativos familiares. Materiales y métodos: estudio, descriptivo y exploratorio. Se aplicó una encuesta on-line, semiestructurada a profesionales de España, Chile, Portugal y Colombia. Se incluyeron tres variables específicas: …
Relaatiotietokannat ja olio-ohjelmointi
2017
Olioparadigma on yleisesti hyväksytty tapa mallintaa sovellusohjelman monimutkaisuutta. Vastaavasti relaatioparadigmaan perustuvat relaatiokannat ovat keskeisessä roolissa tiedon tallentamisessa. Näiden kahden paradigman yhteensovittaminen ei ole ongelmatonta, vaan johtaa olio-relaatioyhteensopimattomuutena tunnettuun ongelmaan. Tämä tutkielma tarkastelee yhteensopimattomuuteen johtavia syitä ja esittelee metodeja sen kanssa selviytymiseksi Object-oriented paradigm is a widely accepted way to control complexity in software. Correspondingly relational databases based on the relational paradigm play a central role in storing information. Combining these two paradigms is not effortless but lea…
Efficient interrogation method of forward Brillouin scattering in optical fibers using a narrow bandwidth long-period grating
2020
A new technique, to the best of our knowledge, for the characterization of the effective refractive index modulation in optical fibers due to transverse acoustic mode resonances excited by electrostriction is reported. The resonances excited by an optical pulse are probed by a narrow bandwidth long-period grating (LPG) inscribed in the fiber, which is interrogated by a continuous wave (CW) beam. The LPG used in this experiment has a narrow bandwidth and high sensitivity to small mode index perturbations, allowing the measurement of index variations from below 10 − 9 to 10 − 6 . Radial and torsional-radial acoustic modes were characterized up to 1.1 GHz. The linewidth of resonances was found…
The relevance of point defects in studying silica-based materials from bulk to nanosystems
2019
The macroscopic properties of silica can be modified by the presence of local microscopic modifications at the scale of the basic molecular units (point defects). Such defects can be generated during the production of glass, devices, or by the environments where the latter have to operate, impacting on the devices’ performance. For these reasons, the identification of defects, their generation processes, and the knowledge of their electrical and optical features are relevant for microelectronics and optoelectronics. The aim of this manuscript is to report some examples of how defects can be generated, how they can impact device performance, and how a defect species or a physical phenomenon …
Water distribution network robust design based on energy surplus index maximization
2015
The aim of this paper is to show that energy surplus indices, such as resilience index, besides providing a very good indirect measure of water distribution network reliability to be adopted during the design phase, represent also a valuable and effective indicator of the robustness of the network in alternative network scenarios, and can thus be profitably used in condition of future demands uncertainty. The methodology adopted consisted of (I) multi-objective design optimization performed in order to minimize construction costs while maximizing the resilience index; (II) retrospective performance assessment of the alternative solutions of the Pareto front obtained, under demand conditions…
Pulsating B and Be stars in the Small Magellanic Cloud
2008
Context: Stellar pulsations in main-sequence B-type stars are driven by the kappa-mechanism due to the Fe-group opacity bump. The current models do not predict the presence of instability strips in the B spectral domain at very low metallicities. As the metallicity of the SMC is lower than Z=0.005, it constitutes a very suitable object to test these predictions. Aims: The main objective is to investigate the existence of B-type pulsators at low metallicities, searching for short-term periodic variability in absorption-line B and Be stars in the SMC. The analysis has been performed in a sample of 313 B and Be stars with fundamental astrophysical parameters accurately determined from high-res…
Enterālās barošanas problēmas māsu praksē intensīvās terapijas nodaļā
2021
Klīniskās barošanas mērķis ir saglabāt vai uzlabot uzturvielu uzņemšanas statusu, novēršot nepietiekamu uzturu un cīnoties ar tā sekām, uzturot ķermeņa audu un funkcionējošu plazmas proteīnu krājumus. Enterālā barošana ietver visas uztura terapijas formas, kas tiek nodrošinātas caur zarnu traktu un kad tiek izmantots speciāls uzturs ar noteiktu medicīnisku mērķi. Pētījuma darba mērķis - noskaidrot enterālās barošanas problēmas pacientam ar nazogastrālo zondi intensīvās terapijas nodaļa un pierādīt izvirzīto hipotēzi, ka pacientam ar nazogastrālo zondi intensīvās terapijas nodaļā ir enterālās barošanas problēmas.
