Multi-scalar critical theories: first steps for a non perturbative functional renormalization group analysis

In this work the fundamental ideas to study properties of QFTs with the functional Renormalization Group are presented and some examples illustrated. First the Wetterich equation for the effective average action and its flow in the local potential approximation (LPA) for a single scalar field is derived. This case is considered to illustrate some techniques used to solve the RG fixed point equation and study the properties of the critical theories in D dimensions. In particular the shooting methods for the ODE equation for the fixed point potential as well as the approach which studies a polynomial truncation with a finite number of couplings, which is convenient to study the critical exponents. We then study novel cases related to multi field scalar theories, deriving the flow equations for the LPA truncation, both without assuming any global symmetry and also specialising to cases with a given symmetry, using truncations based on polynomials of the symmetry invariants. This is used to study possible non perturbative solutions of critical theories which are extensions of known perturbative results, obtained in the epsilon expansion below the upper critical dimension.

Televisite in sanità: un caso studio di configurazione del servizio in conformità alle normative vigenti

L’elaborato ha l’obiettivo di fornire una panoramica piuttosto dettagliata sulla Telemedicina, le prestazioni erogabili in tale modalità ed il quadro normativo vigente, focalizzandosi sulla configurazione e presentazione di un software adibito all’erogazione di Televisite. Il primo capitolo assume un ruolo introduttivo nei confronti della Telemedicina, delle sue applicazioni, dei principali drivers, dei benefici e delle opportunità e dei rischi e delle criticità, correlati all’introduzione di prestazioni erogate in tale modalità. Il secondo capitolo si orienta inizialmente su un’analisi del quadro normativo vigente le prestazioni di Telemedicina, declinato su tre differenti livelli: Unione Europea, Italia ed Emilia-Romagna; proseguendo poi lo studio riguardo l’assetto normativo ed i requisiti necessari per la progettazione e la messa in commercio di un software sanitario. Il terzo capitolo si propone di presentare ed analizzare la configurazione di un software sanitario, attualmente attivo ed in commercio, adibito all’erogazione di Televisite, ossia un atto sanitario in cui il medico interagisce a distanza con il paziente. Si illustrano analiticamente le diverse prospettive degli attori coinvolti: la struttura sanitaria, il medico erogante ed il paziente ricevente la prestazione in modalità telematica. Ci si sofferma su tutti i processi volti alla corretta erogazione della Televisita: la struttura sanitaria è responsabile delle attività di configurazione di back office e delle procedure lato front office, il paziente della creazione dell’utenza web, della prenotazione e dell’accesso alla stanza virtuale ed il medico dell’accesso alla stanza virtuale, dell’erogazione della prestazione e della redazione del referto. Durante l’illustrazione delle procedure dalle diverse prospettive viene fornita anche un’analisi dell'applicativo, soffermandosi su alcune sue caratteristiche fondamentali, tipiche di un software sanitario.

Transmission Of Intra-cellular Genetic Information: A System Proposal.

One of the great challenges of the scientific community on theories of genetic information, genetic communication and genetic coding is to determine a mathematical structure related to DNA sequences. In this paper we propose a model of an intra-cellular transmission system of genetic information similar to a model of a power and bandwidth efficient digital communication system in order to identify a mathematical structure in DNA sequences where such sequences are biologically relevant. The model of a transmission system of genetic information is concerned with the identification, reproduction and mathematical classification of the nucleotide sequence of single stranded DNA by the genetic encoder. Hence, a genetic encoder is devised where labelings and cyclic codes are established. The establishment of the algebraic structure of the corresponding codes alphabets, mappings, labelings, primitive polynomials (p(x)) and code generator polynomials (g(x)) are quite important in characterizing error-correcting codes subclasses of G-linear codes. These latter codes are useful for the identification, reproduction and mathematical classification of DNA sequences. The characterization of this model may contribute to the development of a methodology that can be applied in mutational analysis and polymorphisms, production of new drugs and genetic improvement, among other things, resulting in the reduction of time and laboratory costs.

Beliefs Related To Adherence To Oral Antidiabetic Treatment According To The Theory Of Planned Behavior.

to identify salient behavioral, normative, control and self-efficacy beliefs related to the behavior of adherence to oral antidiabetic agents, using the Theory of Planned Behavior. cross-sectional, exploratory study with 17 diabetic patients in chronic use of oral antidiabetic medication and in outpatient follow-up. Individual interviews were recorded, transcribed and content-analyzed using pre-established categories. behavioral beliefs concerning advantages and disadvantages of adhering to medication emerged, such as the possibility of avoiding complications from diabetes, preventing or delaying the use of insulin, and a perception of side effects. The children of patients and physicians are seen as important social references who influence medication adherence. The factors that facilitate adherence include access to free-of-cost medication and taking medications associated with temporal markers. On the other hand, a complex therapeutic regimen was considered a factor that hinders adherence. Understanding how to use medication and forgetfulness impact the perception of patients regarding their ability to adhere to oral antidiabetic agents. medication adherence is a complex behavior permeated by behavioral, normative, control and self-efficacy beliefs that should be taken into account when assessing determinants of behavior.

Sobre a força de ácidos e bases: algumas considerações

This article intends to answer the question: what is the best way to evaluate the strength of acids and bases? The meaning of the word strength, the main acid-base theories (ionotropic and electron pair), the neutralization reactions and the thermodynamical formalism are considered. Some cases are presented and discussed. In conclusion, evaluating acid-base strength is dependent on the theory (formalism) as well as on the system and measuring techniques.

Princípios fundamentais e modelos de transferência de energia inter e intramolecular

This work outlines the historic development of the concept and main theories of energy transfer, as well as the principal experiments carried out to confirm or refute the proposed theories. Energy transfer in coordination compounds is also discussed with a focus on rare earth systems.

Os caminhos da pragmática no Brasil

This paper traces the history of the study of pragmatics in Brazil. It is shown that Brazilian researches have, by and large, remained attentive to major developments in the field taking place elsewhere in the world. Of particular importance is the burgeoning tendency to focus attention on social issues affecting the day-to-day lives of ordinary people. More and more researchers are realizing the need to assume a critical role in relation to the theories they encounter in the literature.

A língua inglesa no ensino fundamentl I público: diálogos com Bakhtin por uma formação plurilíngue

This article aims at discussing the contributions of the Bakhtinian Circle theories to foreign language teaching and learning (HALL et al., 2005), as far as the first years of formal education in Brazil are concerned. Up to the present moment, foreign languages, including English, are not officially part of the National Curriculum of the first five schooling years. Due to the importance of English in a globalized world and despite all the controversial socio-educational impacts of such an influence, there has been an increase in the interest in this discipline at the beginning years of Brazilian public education (ROCHA, 2006), which has been happening at an irregular pace and without official parameters. Therefore, the relevance of this work lies on the possible guidelines it may offer to support a more effective, situated and meaningful teaching-learning process in that context. Standing for a pluralistic approach to language education, we take the bakhtinian speech genres as organizers of the educational process. We strongly believe that through a dialogic, pluralistic and trans/intercultural teaching (MAHER, 2007), whose main objective is the development of multi (COPE e KALANTZIS, 2000) and critical (COMBER, 2006) literacies, the hybridization of genres and cultures, as well as the creation of third spaces (KOSTOGRIZ, 2005; KUMARAVADIVELU, 2008) can happen. From this perspective, foreign language teaching and learning play a transformative role in society and English is seen as a boundary object (STAR e GRIESEMER, 1989), in and by which diversity, pluralism and polyphony can naturally find their way.

Função vísuo-espacial em paralisia cerebral e proposta de novo teste com a ajuda de computador

The first idea of this study is trat there may be a disturbance of the visuo-spatial function in cerebral palsy. This idea is based upon the theories of Luria and Piaget. The second idea of this study is that the computer can help the investigation of visuo-spatial function. With the intention of evaluating the spatial function in cerebral palsy, the literature related to these themes was revised. We justify the proposal of a new test to study visuo-spatial function. This test uses straight lines in four different orientations and the subject has to recognize and arrange them individually or sets of them. This was done through the use of pencil and papel, and computer. The results confirm that there is a spatial disturbance and that a better understanding of the subject's difficulties was made possible through the use of the computer and the Logo computer language.
