Dynamic Modeling, Energy Analysis, and Path Planning of Spherical Robots on Uneven Terrains
2020
Spherical robots are generally comprised of a spherical shell and an internal actuation unit. These robots have a variety of applications ranging from search and rescue to agriculture. Although one of the main advantages of spherical robots is their capability to operate on uneven surfaces, energy analysis and path planning of such systems have been studied only for flat terrains. This work introduces a novel approach to evaluate the dynamic equations, energy consumption, and separation analysis of these robots rolling on uneven terrains. The presented dynamics modeling, separation analysis, and energy analysis allow us to implement path planning algorithms to find an optimal path. One of t…
Advances on mechanics, design engineering and manufacturing
2018
The theme of the present editorial is dedicated to the“Advances on Mechanics, Design Engineering and Manufac-turing” that emerge in different engineering and architecturalfields.The theme has been chosen as leitmotiv of a series ofevents that have been organized by three societies operatingin Italy, Spain and France, respectively: ADM (Associ-azione nazionale Disegno e Metodi dell’ingegneria indus-triale), INGEGRAF (Asociación Española de IngenieríaGráfica and AIP-PRIMECA (Ateliers Inter-établissementsde Productique—Pôles de Resources Informatiques pour laMECAnique). Since 2014, a series of JCM conferences havebeen organized. JCM is the acronym of “Joint Conference onMechanics, Design Engin…
A Meta-Model for Intelligent Engineering Design of Complex City
2019
A city is a complex system, requiring the input of multiple disciplines for its (re)design. It shares some properties of two kinds of objects: empirical objects as well as theoretical objects. As city emerges as a complex object for multi-disciplinary studies, it is of the highest importance to adopt a systemic and global approach in order to bring new knowledge to this field. To master the growing complexity of cities and to consider in the same spot heterogeneous ways of thinking of city, we need intellectual tools and models. The goal of this paper is to propose a model for describing engineering modelling knowledge with relationships and transformations between four domains: (1) citizen…

2018
Resumen Objetivos Realizar un analisis bibliometrico de los estudios IBERPOC y EPI-SCAN a traves de las bases de datos Science Citation Index y Scopus y conocer la repercusion global y el impacto de la tematica tabaquismo en el estudio IBERPOC. Metodo La busqueda bibliografica general fue realizada en Science Citation Index-Expanded a traves de la plataforma Web of Science (WoS) (Thomson Reuters) y en Scopus el 23 de marzo de 2015. La estrategia de busqueda empleada fue «iberpoc» OR «episcan». La busqueda de las citas se realizo el 15 de octubre de 2015. Resultados Se obtuvieron un total de 24 publicaciones; 13 del estudio IBERPOC (9 sobre «EPOC» y 4 sobre «tabaco») y 11 del estudio EPI-SCA…
Impacto en la asistencia en salud mental tras la colaboración entre atención primaria y salud mental
2021
Resumen Introduccion El medico de atencion primaria es el profesional con el que el paciente psiquiatrico tiene contacto en primer lugar y con mayor frecuencia. Por ello, es fundamental una buena coordinacion entre los servicios de atencion primaria (AP) y salud mental (SM) para brindar la mejor atencion a los pacientes y a la vez optimizar los recursos limitados de ambos servicios. El objetivo de este trabajo es determinar si la colaboracion entre AP y SM da como resultado un manejo mas eficaz de los pacientes con patologia psiquiatrica. Metodologia Se realiza un estudio observacional, retrospectivo, en espejo con una muestra total de 135 pacientes mayores de 16 anos derivados por primera …
Estudio descriptivo y comparativo de factores de riesgo cardiovascular y actividad física en pacientes con síndrome coronario agudo
2018
Resumen: Objetivo: Analizar diversos factores de riesgo cardiovascular en función de la actividad física realizada en pacientes con síndrome coronario agudo (SCA). Diseño: Estudio observacional transversal. Emplazamiento: Servicio de prevención cardiovascular hospitalario (Departamento Salud, Valencia, España). Participantes: Un total de 401 sujetos con SCA y alta hospitalaria entre 2 y 3 meses previos a la medición, entre 30 y 80 años; ausencia de contraindicación para realizar actividad física; sin participación previa en programas de rehabilitación cardiaca. Mediciones principales: Se estimó el equivalente metabólico MET (kcal/kg) según el tipo de actividad, frecuencia, duración e intens…
Association between parental feeding practices and shared family meals. The Food4toddlers study
2020
Background Parental feeding practices and family meals are important determinants for infants' diet and health. Still, there is no previous research of the association between feeding practices and family meals in infants. Objective Explore potential associations between feeding practices and family meals among infants. Design We present cross-sectional results (baseline) from the Food4toddlers study. In total 298 parents of 1-year-olds, recruited from all over Norway, filled in a questionnaire regarding frequency of shared family meals (breakfast, lunch, dinner) and feeding practices using the validated instrument Comprehensive Feeding Practices Questionnaire. Logistic regression was used …
Engineering approaches in siRNA delivery.
2017
siRNAs are very potent drug molecules, able to silence genes involved in pathologies development. siRNAs have virtually an unlimited therapeutic potential, particularly for the treatment of inflammatory diseases. However, their use in clinical practice is limited because of their unfavorable properties to interact and not to degrade in physiological environments. In particular they are large macromolecules, negatively charged, which undergo rapid degradation by plasmatic enzymes, are subject to fast renal clearance/hepatic sequestration, and can hardly cross cellular membranes. These aspects seriously impair siRNAs as therapeutics. As in all the other fields of science, siRNAs management ca…
Application of guidelines for the management of nonalcoholic fatty liver disease in three prospective cohorts of HIV-monoinfected patients
2020
Objectives: Current guidelines recommend use of a diagnostic algorithm to assess disease severity in cases of suspected nonalcoholic fatty liver disease (NAFLD). We applied this algorithm to HIV-monoinfected patients. Methods: We analysed three prospective screening programmes for NAFLD carried out in the following cohorts: the Liver Disease in HIV (LIVEHIV) cohort in Montreal, the Modena HIV Metabolic Clinic (MHMC) cohort and the Liver Pathologies in HIV in Palermo (LHivPa) cohort. In the LIVEHIV and LHivPa cohorts, NAFLD was diagnosed if the controlled attenuation parameter (CAP) was ≥ 248 dB/m; in the MHMC cohort, it was diagnosed if the liver/spleen Hounsfield unit (HU) ratio on abdomin…
Anti-ageing gene therapy: Not so far away?
2019
Improving healthspan is the main objective of anti-ageing research. Currently, innovative gene therapy-based approaches seem to be among the most promising for preventing and treating chronic polygenic pathologies, including age-related ones. The gene-based therapy allows to modulate the genome architecture using both direct (e.g., by gene editing) and indirect (e.g., by viral or non-viral vectors) approaches. Nevertheless, considering the extraordinary complexity of processes involved in ageing and ageing-related diseases, the effectiveness of these therapeutic options is often unsatisfactory and limited by their side-effects. Thus, clinical implementation of such applications is certainly…
