Previsione delle prestazioni del veicolo su strada: stato dell’arte
2016
Questo lavoro contiene una rassegna dei metodi che sono usati per la previsione delle prestazioni del veicolo su strada, in dipendenza del motore installato. La prima parte mostra il calcolo delle resistenze al moto, cioè le forze che il veicolo deve vincere per avanzare sulle strade piane e in salita. Particolarmente interessante appare la parte che riguarda la resistenza aerodinamica, della quale si tratta di metodi sperimentali (galleria del vento), metodi empirici e metodi CFD. Si propone inoltre l’applicazione della norma CUNA sulla velocità per la determinazione dei consumi anche al calcolo dei coefficienti aerodinamici. La rassegna esclude la resistenza accidentale in curva perché no…

Aerosolization Performance of Jet Nebulizers and Biopharmaceutical Aspects
2019
In this work, 13 jet nebulizers, some of which in different configurations, were investigated in order to identify the biopharmaceutical constraints related to the quality attributes of the medicinal products, which affect their safety, efficiency, compliance, and effectiveness. The aerosolization parameters, including the aerosol output, aerosol output rate, mass median aerodynamic diameter, and fine particle fraction, were determined according to the European Standard EN 13544-1, using sodium fluoride as a reference formulation. A comparison between the aerosol output nebulization time and the fine particle fraction displayed a correlation between the aerosol quality and the nebulization …
RSV disease in infants and young children: Can we see a brighter future?
2022
Respiratory syncytial virus (RSV) is a highly contagious seasonal virus and the leading cause of Lower Respiratory Tract Infections (LRTI), including pneumonia and bronchiolitis in children. RSV-related LRTI cause approximately 3 million hospitalizations and 120,000 deaths annually among children <5 years of age. The majority of the burden of RSV occurs in previously healthy infants. Only a monoclonal antibody (mAb) has been approved against RSV infections in a restricted group, leaving an urgent unmet need for a large number of children potentially benefiting from preventive measures. Approaches under development include maternal vaccines to protect newborns, extended half-life monoclon…

Optimization of Spray-Drying Process of
2019
Jerusalem artichoke is an important natural matrix for inulin production. In this experiment, response surface methodology (RSM) was employed to optimize the spray-drying parameters in order to determine the maximal inulin yield. For this study, three independent variables (heating temperature (Tª, 110–120 °C), creep speed (V, 18–22 rpm) and pressure (P, 0.02–0.04 MPa)) were used in the experimental design. Using the Box–Behnken design, the optimal parameters obtained were: drying temperature 114.6 °C, creep speed 20.02 rpm, and pressure: 0.03 MPa. The inulin yield, water content and particle size of inulin obtained by spray-drying and freeze-drying were compared. In this regard, the spray-…
Parental Competence in Infant and Primary Education: design and validation of an instrument
2021
Actualmente, la familia se encuentra ante retos que requieren de su eficiencia y eficacia en la crianza, protección y orientación de los hijos, es decir, la parentalidad y la capacidad de los padres de ejercerla de forma competente. Desde este punto de vista, destaca la necesidad de un modelo educativo centrado en el desarrollo de las competencias parentales que proporcione conocimientos, habilidades y actitudes que optimicen el rol parental respecto al desarrollo pleno y sistémico del ser humano. Ante la necesidad de conocer si los padres asumen de forma óptima su papel en la educación de sus hijos, se plantea como objetivo principal de este artículo el diseño de un instrumento para el aná…
Työyhteisösovittelu vuorovaikutuksen kehittämisen työkaluna
2017
Taloudellisesti haastavina aikoina teollisuudessa on totuttu etsimään tuottavuuden kasvua kovista HR-toimenpiteistä, kuten henkilöstö- ja koulutusleikkauksista. Pehmeämmät keinot ovat jääneet huo- miotta, vaikka henkilöstötuottavuuteen vaikuttavia laatutekijöitä voitaisiin luoda vähäisin kustannuksin esimerkiksi johtamisen ja viestintäkulttuurin avulla. Panostukset organisaation vuorovaikutukseen edis- tävät psyykkisen ja sosiaalisen pääoman rakentumista, ja työniloa lisätessään rakentava kanssakäyminen edistää työtehoa. Merkittävä on myös dialogisen organisaatiokulttuurin rooli eripuran ehkäisemisessä. Pitkittyessään työpaikan konfliktit syövät tehollista työaikaa ja eskaloituneina aiheutt…
El efecto moderador de la edad en la relación entre el valor percibido, las TIC del minorista y la lealtad del cliente
2010
AbstractInformation and communication technology (ICT) may represent a source of benefits for retailers. However, there is a debate in the literature on how ICT influences customer-supplier relationships. In addition, the evidence on the effect of age on consumer attitudes towards retail technological solutions is not conclusive. This paper proposes and tests a model to analyze the influence of retail ICT on consumer loyalty towards the retailer, as well as to assess the moderating role of consumer age on this relationship. As a result, customer assessment of retail ICT, together with perceived value, exerts a positive influence on consumer commitment and satisfaction, being the latter an a…
