Monitoring Commercial Starter Culture Development in Presence of Red Grape Pomace Powder to Produce Polyphenol-Enriched Fresh Ovine Cheeses at Indust…
2021
Red grape Nero d’Avola cultivar grape pomace powder (GPP) was applied during fresh ovine cheese production in order to increase polyphenol content. Before cheeses were produced, the bacteria of a freeze-dried commercial starter culture were isolated and tested in vitro against GPP. Two dominant strains, both resistant to GPP, were identified. Thestarter culture was inoculated in pasteurized ewe’s milk and the curd was divided into two bulks, one added with 1% (w/w) GPP and another one GPP-free. GPP did not influence the starter culture development, since lactic acid bacteria (LAB) counts were 109 CFU/g in both cheeses at 30 d. To exclude the interference of indigenous LAB, the pasteurized m…
Electrochemical incineration of oxalic acid in the presence of NaCl
2008
Recent researches have demonstrated that electrochemical methods offer an attractive alternative to traditional routes for treating wastewaters containing toxic or/and refractory organic pollutants. The effectiveness of the electrochemical treatment depends on many factors including the presence in solution of specie able to act as mediators. In particular, the effect of chloride ions on the performances of the process has been the object of numerous researches. However, up to now, many practical and theoretical aspects about this argument are not completely clear. In the present work, the anodic incineration of oxalic acid (OA) in the presence of NaCl has been investigated with the aim of …
Net currents obtained from zero-average potentials in single amphoteric nanopores
2013
We have studied experimentally and theoretically the rectifying properties of a single asymmetric nanopore functionalized with amphoteric lysine groups and characterized the net current obtained with zero-average time dependent potentials. The pH-controlled rectification phenomena may be relevant to bio-electrochemistry, pH sensing and regulation, and energy conversion. (C) 2013 Elsevier B.V. All rights reserved.
Padomju laika industrializācija Jelgavā: telpiskās struktūras pēctecība un ainava
2015
Bakalaura darbā „padomju laika industrializācija Jelgavā: telpiskās struktūras pēctecība un ainava” tiek vērtēta padomju laika industrializācijas ietekme uz Jelgavas pilsētu, kas visnotaļ pēctecīgi ietekmējis mūsdienu Jelgavas pilsētainavu, tamdēļ var uzskatīt, ka Jelgavas ainava ir padomju industrializācijas mantojums. Balstoties uz lauka darbiem un kamerālām metodēm, autore savā darbā raksturo industrializācijas attīstību un ainavas pārmaiņas gan Rietumeiropas, gan Padomju Savienības, gan Latvijas un Jelgavas vietas mērogā. Vērtējot industrializāciju kā vienu no virzītājspēkiem un kā pēctecīguma procesu, izmantojot pēctecīguma teoriju, tika skaidrota ainavas telpiskās struktūras raksturs …
Calidad de visión y satisfacción del paciente usuario de pantallas de visualización de datos tras cirugía refractiva
2007
Objetivo: Evaluar la influencia en la calidad de vida y satisfacción de los trabajadores usuarios de pantallas de visualización de datos (PVD) que se asocia a la mejora de la función visual tras queratomileusis in situ con láser excimer (LASIK). Métodos: Estudio observacional y longitudinal en una población de 96 pacientes intervenidos de cirugía refractiva con láser excimer según técnica LASIK mediante aplicación de un cuestionario construído al efecto aplicado antes y después de cirugía por un observador independiente. Resultados: Agudeza visual y refracción ocular han mejorado tras LASIK, siendo el índice de eficacia de 1.1. La sensibilidad al contraste tras cirugía mejora en todas las f…
Deindustrialisaatio ja muutoksen hallinta Kouvolassa
2015
Globaalien markkinoiden ja digivallankumouksen myötä Suomen metsäteollisuus on jo pidemmän aikaa käynyt läpi rakenteellista muutosta. Kansainvälinen kilpailu, tehostamisvaatimukset sekä painopaperin kysynnän lasku ovat johtaneet ylikapasiteetin poistoon, joka yhdessä Suomen sisäisen talouden ja elinkeinojen rakennemuutoksen kanssa on vaikuttanut merkittävästi paperiteollisuuden työpaikkojen vähenemiseen. Metsäteollisuuden historia Suomen viennin veturina on oikeuttanut sellu- ja paperiteollisuuden edun ajamista metsä-, energia- ja talouspolitiikassa. Paperiteollisuutta kohdannut rakennemuutos noudattelee myös muita länsimaita kohdannutta perinteisen teollisuuden katoa, mutta onko muutokseen…
Paesaggi minerari in Sicilia: da residuo a risorsa. Strategie e progetto di recupero per il parco minerario Floristella-Grottacalda.
La tesi indaga, attraverso una serie di riflessioni critiche e progettuali, il ruolo che le aree minerarie possono avere nella definizione di nuovi paesaggi. Lo studio si concentra sull'industria dello zolfo in Sicilia, sviluppatasi dalla fine del Settecento e definitivamente dismessa negli anni Ottanta del secolo scorso, con ripercussioni negative sul fronte economico, sociale, ambientale e paesaggistico. La trasformazione delle aree minerarie siciliane richiede una cultura progettuale tale da mettere in relazione architettura, ingegneria, infrastrutture, comunità locali e modelli socio-economici, nel tentativo di esplorare le profonde trasformazioni che questi paesaggi hanno attraversato.…
Efficiency of temporal sensor data compression methods to reduce LoRa-based sensor node energy consumption
2022
Purpose Minimizing the energy consumption in a wireless sensor node is important for lengthening the lifetime of a battery. Radio transmission is the most energy-consuming task in a wireless sensor node, and by compressing the sensor data in the online mode, it is possible to reduce the number of transmission periods. This study aims to demonstrate that temporal compression methods present an effective method for lengthening the lifetime of a battery-powered wireless sensor node. Design/methodology/approach In this study, the energy consumption of LoRa-based sensor node was evaluated and measured. The experiments were conducted with different LoRaWAN data rate parameters, with and without …
Design For Territorial Innovation. Participatory design process and good practices for socio-cultural sustainability
2022
This article studies at length the role of design within territorial socio-cultural transformation. It investigates and describes the industriousness of projects/processes which are particularly effective for social and territorial innovation and are applied above all, to fragile and problematic urban contexts. It focuses on communities and its inhabitants who are often excluded from traditional narrative through some particularly significant projects, with an emphasis on concrete experiences of recent projects in southern Italy. Thus, the article, traverses topics and critical points of a more extensive and profound disciplinary refection, it explores innovative roles of design in the soci…
Melt Processed PCL/PEG Scaffold with Discrete Pore Size Gradient for Selective Cellular Infiltration
2016
In order to develop scaffold able to mimic the natural gradient properties of tissues, biphasic and triphasic approaches were adopted. In this work, polycaprolactone/polyethylene glycol (PCL/PEG) scaffolds were prepared by using a combination of melt mixing and selective leaching without harmful solvents. The method permitted to develop three-layer scaffolds with high control of porosity and pore size. The mechanical properties were evaluated under physiological condition in order to simulate the real conditions of work. Co-culture of osteoblastic and fibroblastic mice cells were carried out in order to study the differential cellular permeation through the different pore size layers.
