No full textDevelopment of a supercritical fluid extraction method for determination of total fat content in fish products.
No full textA supercritical fluid extraction method was developed for the assessment of the fat content in fish products. Various fish species (bass, salmon, eel, cod, tuna) having a fat content ranging from 0.2 to 25%, were utilized in the study as fresh or commercially frozen products. The fat recovery efficiency of Soxhlet, Bligh and Dyer and supercritical CO2 extraction methods was compared and the optimized working parameters with supercritical CO2 were 35 MPa, 60 °C,
and use of EtOH (5% mol/mol) as modifier
Improving neuropsychiatric symptoms following stroke using virtual reality: A case report
No full textRATIONALE: Post-stroke cognitive impairment occurs frequently in patients with stroke, with a 20% to 80% prevalence. Anxiety is common after stroke, and is associated with a poorer quality of life. The use of standard relaxation techniques in treating anxiety in patients undergoing post-stroke rehabilitation have shown some positive effects, whereas virtual reality seems to have a role in the treatment of anxiety disorders, especially when associated to neurological damage. PATIENTS CONCERNS: A 50-year-old woman, smokers, affected by hypertension and right ischemic stroke in the chronic phase (i.e., after 12 months by cerebrovascular event), came to our observation for a severe anxiety state and a mild cognitive deficit, mainly involving attention and visuo-executive processes, besides a mild left hemiparesis. DIAGNOSIS: Anxiety in a patient with ischemic stroke. INTERVENTIONS: Standard relaxation techniques alone in a common clinical setting or the same psychological approach in an immersive virtual environment (i.e., Computer Assisted Rehabilitation Environment - CAREN). OUTCOMES: The patient's cognitive and psychological profile, with regard to attention processes, mood, anxiety, and coping strategies, were evaluated before and after the 2 different trainings. A significant improvement in the functional and behavioral outcomes were observed only at the end of the combined approach. LESSONS: The immersive virtual reality environment CAREN might be useful to improve cognitive and psychological status, with regard to anxiety symptoms, in post-stroke individuals

No full textForecasting stock price movements using neural networks
No full textIncludes bibliographical references (p. 99-101).The prediction of security prices has shown to be one of the most important but most difficult tasks in financial operations. Linear approaches failed to model the non-linear behaviour of markets and non-linear approaches turned out to posses too many constraints. Neural networks seem to be a suitable method to overcome these problems since they provide algorithms which process large sets of data from a non-linear context and yield thorough results. The first problem addressed by this research paper is the applicability of neural networks with respect to markets as a tool for pattern recognition. It will be shown that markets posses the necessary requirements for the use of neural networks, i.e. markets show patterns which are exploitable
The Tax Sensitivity of Foreign Direct Investment: Evidence from Firm-Level Panel Data
No full textUnderstanding the determinants of foreign direct investment (FDI) is important for analyzing capital flows and the industrial organization of multinational firms. Most empirical studies of FDI, however, have focused on case studies of nontax factors in overseas investment decisions or on discerning reduced-form relationships between some measure of FDI and variables relating to nontax and tax aspects of the investment decision. In this paper, we examine the effects of taxation on FDI using previously unexplored (for this purpose) panel data on FDI by subsidiaries of U.S. multinational firms collected by Compustat's geographic segment file project. These firm- level data contain information on new capital investment overseas which enable us to measure tax influences on FDI more precisely and allow us to focus on structural models of subsidiaries' investment decision. Our empirical results cast significant doubt on the simplest notion that 'taxes don't matter' for U.S. firms' FDI decisions. Tax parameters influence FDI in precisely the way indicated by neoclassical models. Our results also lend support to the application of the 'tax capitalization' model to the study of dividend repatriation and foreign direct investment decisions.
“Voi che ve ne andaste per paura” ovvero tre sguardi sulla battaglia di Montaperti
No full textL’obiettivo che si pone l’articolo č quello di esaminare le diverse prospettive in cui fu percepita la battaglia di Montaperti, combattuta nel 1260 tra guelfi fiorentini e ghibellini senesi, sostenuti a loro volta dagli esuli ghibellini di Firenze. Questo scontro s’impresse durevolmente nella memoria dei membri di ambedue i partiti rivelando quanta importanza avesse per gli italiani dell’epoca l’appartenenza a un raggruppamento politico determinato. In una tale ottica, l’adesione a una data fazione va ritenuta un tratto italiano per antonomasia che, seppure in una forma rudimentale, č sopravvissuta per secoli. Basti pensare al Palio di Siena, che puň esser visto come un prolungamento della rivalitŕ tra guelfi e ghibellini. Ai fini della ricerca sono stati analizzati: il sonetto ***[A voi che ve ne andaste per paura] di Rustico Filippi (di Filippo) – ghibellino fiorentino che deride lo sbaraglio dei guelfi, il Canto X dell’Inferno, in cui Dante parla con il capo degli esuli ghibellini fiorentini, Farinata degli Uberti, e la canzone ***[Ahi lasso! or e stagion de doler tanto] di Guittone d’Arezzo che constata con amarezza che Firenze č ormai soltanto un simulacro dell’antica grandezza. Viene inoltre segnalato che tra le righe dei componimenti traspare un’altra caratteristica tipicamente italiana, quella di una specie di campanilismo, ovverossia di patriottismo locale.Artykuł ukazuje różne literackie spojrzenia na bitwę pod Montaperti z 1260 r.: potyczkę o ogromnym znaczeniu w historii walk gwelfów i gibelinów, które można postrzegać jako przejaw campanilismo, tj. lokalnego patriotyzmu. Tytułem wstępu zostaje nakreślone ówczesne tło społeczno-polityczne, rywalizacja partii jest wpisana w szerszy kontekst. Aby uzmysłowić konsekwencje starcia, autorka pracy wzmiankuje o jego niszczycielskich skutkach, w tym o zamiarze zrównania Florencji z ziemią przez zwycięskich gibelinów. Na szczęście w samą porę powstrzymuje ich Farinata degli Uberti, z punktu widzenia którego oglądamy bitwę w Pieśni X Piekła Dantego.
Zdaje się, że również Rustico di Filippo w sonecie ***[A voi, che ve ne andaste per paura], skierowanym do gwelfów, ceni wyżej wspólne dobro niż zwycięstwo w politycznych potyczkach, zważywszy że wyznaje: „nie chcę z wami żyć w niezgodzie” (“io non voglio con voi stare a tenzone”). Podobną postawę przyjmuje Guittone d’Arezzo w słynnej kanconie ***[Ahi lasso! or č stagion de doler tanto], w której ubolewa nad wewnętrzną niezgodą wśród mieszkańców Florencji. Tym, co łączy wszystkich autorów, jest zatem płomienna miłość do miasta
Temporality in L2 Spanish: an investigation of the expression of temporality in the narrative discourse of Spanish L2 learners
No full textThe general objective o f this research study is the investigation of the development of the expression of temporality in Second Language Acquisition. In particular, this study examines the acquisition process by native English speakers who are second languages learners of Spanish Temporality is examined as it is manifested in the oral narration of events by these learners. The theoretical argument behind the research is based on linguistic relativity and “thinking for speaking” theories which consider how different languages deal with the linguistic coding of certain concepts, such as time and space, and the influence of linguistic forms on speakers’ perceptions and cognitive development of these concepts. The present study aims to answer the following question.
If the language they speak influences the manner in which speakers conceptualise temporal relations, will learners of a second language adopt the cognitive strategies and styles of the native speakers to refer to events in time, as their Interlanguage develops to approximate the target language? Specifically, will second language learners of Spanish adopt the patterns of temporal expression m narrative discourse, typical of Spanish native speakers? To answer this question standard qualitative and quantitative methods of research used in applied linguistics are utilized
