Tecnologie digitali, poteri datoriali e diritti dei lavoratori
2022
Il volume analizza le tecnologie digitali e il loro impatto sui rapporti di lavoro. In particolare, tenuto conto dell'incidenza degli strumenti tecnologici sui vincoli gerarchici e sulla natura e le modalità di esercizio dei poteri dell’imprenditore nei confronti di chi presta lavoro, il volume si interroga sugli effetti specifici che ne derivano per i principi di dignità, libertà e sicurezza sanciti dalla Costituzione. Al contempo si indicano le soluzioni proposte dall’ordinamento giuridico sul piano della delimitazione di quei poteri e della salvaguardia di quei principi.
Problemi di Conservazione di un'opera di Land Art di straordinarie dimensioni: il Grande Cretto di Alberto Burri a Gibellina (TP)
2009
This work deals with the conservation of one of the largest land art works in the world. It is a sort of white shroud laid on the ruins of the town of Gibellina, Sicily, after the tremendous earthquake of January 1968. The most significant aspects of the degradation phenomena observed on site are related to some faults in the construction, due to the prevailing of the artistic requirements over the good rules of concrete technology. Furthermore the guidelines for both a conservation intervention and the subsequent maintenance of the art work are also indicated.
All polarization-maintaining assively mode-locked yb-doped fiber laser : pulse compression using an anomalous polarization-maintaining photonic cryst…
2019
We report the generation of short pulses at 1 μm using an all-polarization-maintaining (PM) fiber configuration. The pulses are provided by an all normal-dispersion Fabry-Perot Yb-doped cavity and are compressed with an anomalous polarization-maintaining photonic crystal fiber (PM PCF). Opposed to standard configurations; here the filtering action is solely performed by the finite bandwidth of the gain medium. The laser generates 8 ps width sech 2 profile pulses at 1046.8 nm with a −10 dB bandwidth of 5.9 nm. After compression using the PM PCF, pulses with an FWHM of 3 ps were obtained, limited by the actual value of the available anomalous dispersion. We also report the changes in the outp…
Tratamiento cognitivo-conductual de la adicción a videojuegos de rol online: fundamentos de propuesta de tratamiento y estudio de caso
2014
Resumen: El proposito de este trabajo es presentar una propuesta de tratamiento cognitivo-conductual para la intervencion en la adiccion a videojuegos. Se presenta el caso de un varon de 21 anos con problemas con el uso de los videojuegos. Se expone el procedimiento en cada una de las fases de las que consta el tratamiento, asi como los resultados de su eficacia en un estudio de caso. Despues de trece semanas de intervencion se aprecian importantes cambios en el nivel de dependencia. Los resultados muestran una disminucion significativa del tiempo de uso del ordenador y de juego, asi como una mejoria del funcionamiento personal y social del paciente. Palabras clave: Adiccion a videojuegos; …

Effect of abrasive pretreatment on hot dried goji berry
2015
Goji (Lycium barbarum L.) is a Solanaceous deciduous shrub that grows in China, Tibet and other parts of Asia. Nowadays, goji berries are known as being very rich in nutrients with high antioxidant capacity, fact for which they were included in the novel category of “superfruits”. Goji berries contain high amounts of antioxidants, carotenoids, vitamin A and zeaxanthin. Most of goji berries produced are dried because they are very delicate fruits. Drying process improves fruit stability, since it decreases considerably the water activity of the food, reduces microbiological and enzymatic activity and minimizes physical and chemical reactions during storage. However, drying of goji berries ca…
Sorafenib in Mice – A Pharmacokinetic Study
2015
Pharmacokinetic models are applied to determine the drug distribution in the organism with respect to a given administration. Models based on body anatomy and physiology can provide an accurate description of drug concentrations reached in specific organs and tissues of mammals. This article proposes a model based on mammalian anatomy and physiology to predict the biodistribution in mice of sorafenib, an anti-cancer drug, with specific attention to the concentration reached in the liver, as that is the action site in case of hepatocellular carcinoma treatment. The model reveals a close correspondence respect to experimental concentration data in the organism and also assesses with good fide…
Kefiran-based Scaffolds For Biomedical Applications
2018
Kefiran is an exopolysaccharide produced by microorganisms present in kefir grains, with several health promoting properties. A optimized protocol was developed for the separation of kefiran from kefir grains, allowing to reach a yield 4÷5 % without using toxic or expensive chemicals. The capability of kefiran to produce scaffold via Thermally Induced Phase Separation (TIPS) technique was investigated and porous scaffolds structure was obtained. Separated kefiran and scaffolds were analyzed via DSC and different thermal properties between purified kefiran and scaffold were revealed. XRD analysis revealed different structure between kefiran and scaffolds. The porous scaffold structure can be…
Production of a a-L-Rhamnosidase from Aspergillus Terreus Using Citrus Solid Waste as Inducer for Application in Juice Industry
2012
Naringinase is an enzyme complex consisting of a a-L-rhamnopyranosidase (Rha, EC. 3.2.1.40) and ß-D-glucopyranosidase (ßG, EC. 3.2.1.21). a-L-rhamnopyranosidase is an enzyme of considerable importance in food technology for increasing the aroma of fruit juices and alcoholic beverages. It is particularly used for debittering of citrus-juice by the hydrolysis of naringin and hesperidin, however this activity is low in commercial enzyme preparations. The aim of this work is the production of Rha from Aspergillus terreus fermentation using citrus solid waste (CSW), called “pastazzo”, as specific inducer. CSW is rich in fermentable materials such as sugars, in particular rhamnose, in pectins, an…
Drying kinetics and physico-chemical quality of mango slices
2019
Mango (Mangifera indica L.) is an important tropical fruit consumed worldwide and grown in Italy only in Sicily, where the areas of the Tyrrhenian coast have proved to be suitable to produce valuable fruits. Mango fruit has a pleasant aroma and taste, which are important qualities for consumer’s sensorial acceptance. However, they are highly perishable, prone to progressive undesired changes if stored untreated, resulting in around 25% postharvest losses, which is further increased during storage and transportation. An alternative for reducing the above-mentioned undesired changes is the dehydration of the cut fruit, which reduce the fruit water activity, thereby avoiding the deteriorative …
