Extension of Tosela cheese shelf-life using non-starter lactic acid bacteria
2011
Six strains of non-starter lactic acid bacteria (NSLAB) were used to extend the shelf-life of the fresh cheese Tosèla manufactured with pasteurised cows’ milk. The acidification kinetics of three Lactobacillus paracasei, one Lactobacillus rhamnosus and two Streptococcus macedonicus were studied in synthetic milk medium. Lb. paracasei NdP78 and NdP88 and S. macedonicus NdP1 and PB14-1 showed an interesting acidifying capacity and were further characterised for growth in UHT milk and production of antimicrobial compounds. Lb. paracasei NdP78 and S. macedonicus NdP1 grew more than 2 log cycles in 6 h. Lb. paracasei NdP78 was also found to produce a bacteriocin-like inhibitory substance (BLIS) …
Identification of major histocompatibility complex class II-associated peptides derived from freshly prepared rat Langerhans cells using MALDI-PSD an…
2000
The isolation and identification is described of MHC class II-bound peptides derived from Langerhans cells. A combination of preparative micro-HPLC, MALDI-MS, Edman degradation was used for determining the amino acid sequence of MHC-associated peptides. Sample handling was crucial because fractions containing trace amounts of material require immediate storage at −80 °C to prevent peptide losses.
Analysis of the ATLAS Rome Production Experience on the LHC Computing Grid
2006
The Large Hadron Collider at CERN will start data acquisition in 2007. The ATLAS (A Toroidal LHC Apparatus) experiment is preparing for the data handling and analysis via a series of Data Challenges and production exercises to validate its computing model and to provide useful samples of data for detector and physics studies. The last Data Challenge, begun in June 2004 and ended in early 2005, was the first performed completely in a Grid environment. Immediately afterwards, a new production activity was necessary in order to provide the event samples for the ATLAS physics workshop, taking place in June 2005 in Rome. This exercise offered a unique opportunity to estimate the reached improvem…
A chemometric approach to evaluate the impact of pulses, Chlorella and Spirulina on proximate composition, amino acid, and physicochemical properties…
2019
Changes in physicochemical parameters, proximate composition, amino acid and taste profiles of turkey burgers enriched at 1% with soy (control), pulses, Chlorella and Spirulina proteins were studied. Results: Color parameters, pH, ash content, total, essential and non-essential amino acids were significantly different among the different type of turkey burgers prepared. In this regard, turkey burgers made with pea protein presented the highest values for pH and lightness, whereas the samples prepared with broad bean showed the highest redness. The inclusion of bean and seaweed produced a marked increase of glutamic acid, lysine and aspartic acid. However, the taste profile was similar in th…
Influence of the early bacterial biofilms developed on vats made with seven wood types on PDO Vastedda della valle del Belìce cheese characteristics
2019
Early vat bacterial biofilms developed spontaneously through contact with whey have been characterized on seven wood types (Castanea sativa Miller, Cedrus libani, A. Rich., Prunus avium L., Fraxinus ornus L., Juglans regia L., Pinus nigra J.F. Arnold and Populus nigra L.). The present study aimed to evaluate the influence of these biofilms on the microbiological, chemical, physical and sensory characteristics of PDO Vastedda della valle del Belìce (VdB) cheese, processed traditionally from raw ewe's milk using wooden tools. To this purpose, the experimental cheeses after 15 d of refrigerated storage were examined. Lactic acid bacteria (LAB) populations dominated the microbial community of a…
Degradation of Carotenoids in Apricot (Prunus armeniaca L.) During Drying Process
2013
"Carotenoids are natural compounds whose nutritional importance comes from the provitamin A activity of some of them and their protection against several serious human disorders. The degradation of carotenoids was investigated during apricot drying by microwave and convective hot-air at 60 and 70 A degrees C. Seven carotenoids were identified: antheraxanthin, lutein, zeaxanthin, beta-cryptoxanthin, 13-cis-beta-carotene, all-trans-beta-carotene and 9-cis-beta-carotene; among these, all-trans-beta-carotene was found to be about 50 % of total carotenoids. First-order kinetic models were found to better describe all-trans-beta-carotene reduction during drying, with a degradation rate constant (…
Kinetics of carotenoids degradation and furosine formation in dried apricots (Prunus armeniaca L.)
2017
Abstract The kinetics of carotenoid and color degradation, as well as furosine formation, were investigated in apricot fruits during convective heating at 50, 60 and 70 °C. Degradation of carotenoids and color, expressed as total color difference (TCD), followed a first and zero order kinetic, respectively. The activation energy (Ea) for carotenoids degradation ranged from 73.7 kJ/mol for 13- cis -β-carotene to 120.7 kJ/mol for lutein, being about 91 kJ/mol for all- trans -β-carotene. Violaxanthin and anteraxanthin were the most susceptible to thermal treatment. The furosine evolution was fitted at zero order kinetic model. The Ea for furosine formation was found to be 83.3 kJ/mol and the Q…
Veien fra Bee-Bot til Scratch : En casestudie om hvilke kunnskaper elevene sitter igjen med etter å ha prøvd to ulike programmeringsverktøy
2019
Masteroppgave matematikkdidaktikk MA502 – Universitetet i Agder 2019 The way from Bee-Bot to Scratchis a case study that looks at what competencies the pupilsmanage to pass from anobject programminglanuageto a computer-based programming language.Because programming comes under the core elements of mathematics in the new curriculum that is initiated in the autumn of 2020, I have chosen this research question: "Can the pupils' programming knowledgefrom Bee-Bot be transferred to Scratch in a mathematics session,focusing on computational thinkingand creativity?" The study therefore focusesat howmuch of the various topicsemerge and which competences the pupils manage to pass on from the programm…
Design of a VR application for pilots as a complementary tool for procedure training of Abnormal Operations
2021
Master's thesis in Multimedia and educational technology (MM506) The aviation industry has been amongst the early adopters of VR for educational purposes, even since the very beginning of VR’s technology establishment and throughout its further development. Flight simulators are invaluable as they let pilots and instructors replicate any situation for learning full control over the plane and improve situational awareness without paying the price of life-safety if using an actual aircraft. Abnormal operations and their procedures are a key subject of safety training, where pilots have to understand and memorize particular orders of actions in order to solve a dangerous situation on board. A …
VR formidling av en kunstnerisk opplevelse : Dette prosjektet er en interaktiv kunstinstallasjon laget i VR for Sørlandets Kunstmuseum
2021
Master's thesis in Multimedia and educational technology (MM506) I denne masteroppgaven har vi laget en VR-simulering for Sørlandets Kunstmuseum i Kristiansand. Ønsket med denne formidlingen var å vekke kunstinteressen hos publikum og undersøke om dette kan være et medium som kan bidra til økt museumsbesøk. Prosjektet har tatt utgangspunkt i fire verk som er malt av den norske kunstneren Reidar Aulie. Det har blitt utført en metodetriangulering brukeranalyse med VR-simuleringen og tradisjonell kunst, som har vært med på å dra sammenligninger mellom de to ulikeformidlingene. Dette har vært med på å bekrefte eller avkrefte vår hypotese; Bruk av VR i formidling av kunst vil bidra til større in…
