Kaon nucleon scattering in lattice QCD

In this paper I discuss why one would want to study meson baryon interactions within the framework of lattice QCD, and what I have contributed to this area of research. I begin with a little background on QCD, and Chiral theories. I analyze Kaon Nucleon scattering, and calculate the Kaon Nucleon scattering length from data obtained using a lattice QCD simulation. Therefore, I show that it is possible to use Lattice QCD simulation to extract observables. This is important in areas where experiments are challenging or impossible with current technologies

Theory and ab initio simulation of atomic heat transport

The Green-Kubo formalism, routinely used in combination with classical molecular dynamics for thermal conductivity calculations, is in this thesis extended for application in an ab initio DFT framework. An expression for the adiabatic energy flux from density-functional theory is derived and the resulting thermal conductivity is shown to be unaffected by the inherent ill-definedness of quantum mechanical energy densities and currents. The methodology is demonstrated by comparing results from ab-initio and classical molecular-dynamics simulations of a model liquid-Argon system, for which accurate inter-atomic potentials are derived by the force-matching method,and finally applied to compute the thermal conductivity of heavy water at ambient conditions

Dante's Inferno and the McGill Pain Questionnaire

Aims of the study: To study the images which depict the damned's sufferings in Dante's Inferno, in their expression of the several meanings of "pain", the semantics of "pain" in the poem has been analyzed, eventually trying to determine whether the organization of punishments of Inferno may somehow mirror a disability scale. Methods: A detailed analysis of the text was carried out, which proved a valuable tool for interpreting the organization of punishments as a possible disability scale. The semantics of pain in the Divine Comedy was studied through all the forms of the pain descriptors (included the archaic terminological forms) from the Italian version of the McGill Pain Questionnaire (MGPQ) by Maiani and Sanavio. Results and Conclusions: In Dante's Inferno a classification of pain is provided, based on the experience of sufferings; Dante's images seem not only instrumental to investigating the sensorial but also the affective and intellectual spheres by introducing a number of characters and describing the impact of punishment onto their souls. Our research highlighted that 46 out of 78 terms from the MGPQ are present in Inferno, though with different forms; the Groups the MGPQ is divided into are also represented with the exception of Group XII, the most frequently detected being Groups XIII-which studies the fear-related sensations in the emotional sphere - XIV, XIX and XX. The great attention emerges that Dante devoted to describing simple sensorial experiences as well as the way punishments affected the soul. As a whole, the terms pertaining to the sensorial sphere are the most frequently encountered. The lack of motion which increases circle after circle in Hell, well matches the progressing physical and psychological impairment caused by some invalidating diseases. Noticeably, Dante created such a complex system centuries before the studies were released on the impact of pain and its quantitative and mostly qualitative definition. In conclusion, this interpretation suggests that the writing on the door to Hell which leads Dante into the inaccessible world of "the miserable race, those who have lost the good of intellect", may well be the title of a precise and incredibly up to date classification of painful sensations which are wonderfully described with simple and suggestive examples each time transforming into powerful images. …"Through me road to the city of desolation, / Through me the road to sorrows diuturnal, / Through me the road among the lost creation"

Geocoding health data with Geographic Information Systems: a pilot study in northeast Italy for developing a standardized data-acquiring format

Introduction. Geographic Information Systems (GIS) have become an innovative and somewhat crucial tool for analyzing relationships between public health data and environment. This study, though focusing on a Local Health Unit of northeastern Italy, could be taken as a benchmark for developing a standardized national data-acquiring format, providing a step-by-step instructions on the manipulation of address elements specific for Italian language and traditions. Methods. Geocoding analysis was carried out on a health database comprising 268,517 records of the Local Health Unit of Rovigo in the Veneto region, covering a period of 10 years, starting from 2001 up to 2010. The Map Service provided by the Environmental Research System Institute (ESRI, Redlands, CA), and ArcMap 10.0 by ESRI\uae were, respectively, the reference data and the GIS software, employed in the geocoding process. Results. The first attempt of geocoding produced a poor quality result, having about 40% of the addresses matched. A procedure of manual standardization was performed in order to enhance the quality of the results, consequently a set of guiding principle were expounded which should be pursued for geocoding health data. High-level geocoding detail will provide a more precise geographic representation of health related events. Conclusions. The main achievement of this study was to outline some of the difficulties encountered during the geocoding of health data and to put forward a set of guidelines, which could be useful to facilitate the process and enhance the quality of the results. Public health informatics represents an emerging specialty that highlights on the application of information science and technology to public health practice and research. Therefore, this study could draw the attention of the National Health Service to the underestimated problem of geocoding accuracy in health related data for environmental risk assessment

Organizational model for a telepathology system

The technological development of telemedicine has performed important progress, assuming a diagnostic relief role inside of the processes. Among the fields in fast evolution, telepathology is placed among those of greater interest. Up to some years ago, telepathology allowed us to observe at a distance and in real time, histological or cytological slides through the Internet, using a motorized microscope (dynamic telepathology). Currently, telepathology has completed an important step in ahead being possible to digitize completely a slide and to store it. This allows observation of the whole surface of histological or cytological slides remotely with a customary PC, without human intervention (virtual slide). The described systems have exclusive characteristics, so that a "hybrid system" supporting both technologies, turns out to be the best solution applicable in a wide range program. In order to realize the theoretical aspects previously described, we report an organizational model practicable and applicable to a territory in which three hospitals operate. An essential prerequisite in order to arrange an efficient telepathology system turns out to be one structured data transmission network, equipped with elevated guaranteed bandwidth, and one consolidated experience in the registration and management of digital images

Effect of aging and degeneration on the human intervertebral disc during the diurnal cycle: A finite element study

Alterations in the major biochemical constituents of intervertebral discs coincide with aging and degeneration, and can alter the disc's ability to support load. The most significant biochemical change that occurs in degeneration is the loss of proteoglycans in the nucleus pulposus. During a diurnal cycle, the disc experiences approximately 16 hours of functional loading, followed by 8 hours of recovery. An axisymmetric, poroelastic model was created using ABAQUS finite element software. Standard poroelastic theory is utilized, but a user-defined material was written to include the effects of osmotic swelling, which is directly related to proteoglycan content. Due to the high stresses in the nucleus, the annulus fibrosus must remodel itself to account for the change in properties of the nucleus. The stress experienced by the nucleus increases greatly in Grade 2 from Grade 1, but then decreases in Grade 3, and even Grade 4 experiences lower stresses than in Grade 2. The osmotic pressure in the central nucleus decreases approximately 75% with degeneration. This explains the increasing inability of Grades 3 through 5 to recover the fluid lost during loading, since the osmotic pressure gradient is the primary mechanism with which fluid flows back into the disc
