Investigating Energy Saving Potential in a Big Shopping Centre through Ventilation Control

2018

This work shows an example of energy saving interventions on the ventilation system of a big shopping center. This kind of buildings is characterized by high energy consumptions, because of the high level of yearly operating hours and the use of obsolete technologies. In the case study, a big Do It Yourself (DIY) shop located in the southern part of Italy is analyzed, proposing two different approaches aimed at reducing the annual energy consumption for the indoor air exchange of the sales area. In the AS-IS scenario, a centralized HVAC plant, composed by six rooftops, is installed on the roof of sales area, working with fixed airflow value. The first retrofit solution involves the installa…

A qualitative study on the role of the built environment for short walking trips

2015

The present study uses a qualitative approach with the aim to identify built environmental factors influencing short walking distances for transportation among adults (18-65 years), with special attention to micro-scale attributes. Three focus groups were held in Valencia (Spain) and conducted with participants who undertook, at least once a week, one short non-shopping trip in any travel mode (were "short trip" is defined as less than 3045 min walking distance). A thematic analysis of the data was performed and six categories of factors emerged related to the built environment. Factors were also classified as either barriers to walking, or secondary factors related to the attractiveness of…

On the methods of nonsmooth optimization

2005

In this paper we shall give a short derivation of the most promising methods in nonsmooth optimization, namely bundle methods. We introduce the basic bundle idea due to Lemarechal and several modifications by Kiwiel, Schramm and Zowe. To the end we shall give some numerical results comparing the efficience of these methods. As test problems we have used well-known test problems from litterature and in addition we shall give some contributions to nonsmooth optimal control problems.

ESRA19-0543 Analgesic effects of dexamethasone when given perineurally or intravenously in the upper arm bone fracture and shoulder joint surgery

2019

Background and aims Shoulder surgery is associated with severe pain. Pain delays rehabilitation and lowers quality of life. Finding adjuvants to the LA to improve analgesia and facilitate mobilization has been the focus of researchers recently. The aim of this work was to investigate which administration methods—dexamethasone perineural or intravenously—prevents pain more effectively. Methods Prospective, randomized study conducted at Hospital of Traumatology and Orthopaedics after ethics committee approval. Study involved 75 patients with upper limb fracture or shoulder joint surgery in RA and GA. Group I: Bupivacaine 0.25% 70 mg + Dexamethasone 8 mg perineurally Group II: Bupivacaine 0.25…

El efecto mediador y moderador de la internacionalización en la relación entre los sistemas de control de gestión y el compromiso con la innovación

2019

La literatura contable revela resultados contradictorios al evaluar el efecto que los diferentes usos de los sistemas de control de gestión (SCG) tienen en la innovación. Siguiendo el marco teórico establecido por Simons (1995), este trabajo prueba el efecto que la internacionalización, bien sea directo, mediador o moderador, tiene en la relación entre el uso interactivo de los SCG y el compromiso de las empresas con la innovación. Tomando una muestra de 231 organizaciones del sector agroalimentario español, los resultados obtenidos ponen de manifiesto la ausencia de una relación directa entre el uso interactivo del conjunto de herramientas de SCG y el compromiso con la innovación. Del mism…

Circulating CD34+ progenitor cells () gained importance in the field of regenerative medicine due to their potential to home in on injury sites and differentiate into cells of both endothelial and osteogenic lineages. In this study, we analyzed the mobilization kinetics and the numbers of CD34+, CD31+, CD45+, and CD133+ cells in twenty polytrauma patients (n = 13 male, n = 7 female, mean age 46.5±17.2 years, mean injury severity score (ISS) 35.8±12.5 points). In addition, the endothelial differentiation capacity of enriched CD34+cells was assessed by analyzing DiI-ac-LDL/lectin uptake, the expression of endothelial markers, and the morphological characteristics of these cells in Matrigel an…

SOCS3 transactivation by PPARγ prevents IL-17-driven cancer growth.

2013

Abstract Activation of the transcription factor PPARγ by the n-3 fatty acid docosahexaenoic acid (DHA) is implicated in controlling proinflammatory cytokine secretion, but the intracellular signaling pathways engaged by PPARγ are incompletely characterized. Here, we identify the adapter-encoding gene SOCS3 as a critical transcriptional target of PPARγ. SOCS3 promoter binding and gene transactivation by PPARγ was associated with a repression in differentiation of proinflammatory T-helper (TH)17 cells. Accordingly, TH17 cells induced in vitro displayed increased SOCS3 expression and diminished capacity to produce interleukin (IL)-17 following activation of PPARγ by DHA. Furthermore, naïve CD4…

Are drivers’ attentional lapses associated with the functioning of the neurocognitive attentional networks and with cognitive failure in everyday lif…

2013

Abstract Driver distraction and inattention are considered among the major contributing factors in road traffic crashes. One of the most widely used tools to study drivers’ attentional lapses and other types of aberrant behaviour is the Driver Behaviour Questionnaire (DBQ). In the present work, further evidence of the feasibility of the DBQ to study driver inattention is provided. The relationships between the DBQ and both a computer-based neurocognitive test on attentional performance (the Attention Network Test for Interactions and Vigilance, ANTI-V) and a self-reported measure of cognitive failure (the Cognitive Failures Questionnaire, CFQ) are analysed. Results show that attentional lap…

Field Oriented Control of IPMSM Fed by Multilevel Cascaded H-Bridges Inverter with NI-SOM sbRIO-9651 FPGA controller

2022

Electrical drives fed by Multilevel Inverters (MIs) are of considerable interest for traction and e-mobility applications. In detail, Cascaded H-Bridge Multilevel Inverter (CHBMI) is a promising solution for electrical drive optimization purposes in terms of efficiency, safety, integration and flexible use of energy sources. The aim of this paper is the experimental implementation of the field-oriented control strategy of Interior Permanent Magnet Synchronous Machine (IPMSM) fed by CHBMI by use of NI-SOM sbrRIO-9651 FPGA controller. This FPGA controller can be programmable in the LabVIEW programming environment with the consequent benefits of graphical programming. The paper address the acq…

Adolescents' school-related self-concept mediates motor skills and psychosocial well-being.

2014

Background The health benefits of exercise participation and physical activity for mental health and psychosocial well-being (PSWB) have been shown in several studies. However, one important background factor, that is, motor skills (MSs), has largely been ignored. In addition, most of the existing research focuses on poor MSs, that is, poor MSs are often connected to poorer PSWB. The mechanism linking MSs and PSWB is unclear. However, a preliminary suggestion has been made that self-worth or self-perceptions might mediate the association between MSs and PSWB. Aim We investigated whether the self-concepts (SCs) of school-related physical education (SCPE), reading (SCR), and mathematics (SCM)…
