Abstract: Although the risk of acquisition of hepatitis B or hepatitis C virus through blood products has considerably reduced since the last decade, some infected patients are candidates to stem cell transplantation. Others may have no alternative than an infected donor. In all these cases, recipients of transplant are prone to short and long term liver complications. The evolution of liver tests under chemotherapy before transplant may give useful information to anticipate on the risk of hepatitis reactivation after transplant, both for HBv and HCv. More than sixty percent of the patients who are HBsAg-positive before transplant reactivate after transplant, and 3% develop acute severe liver failure. Because both viral replication and immune reconstitution are the key factors for reactivation, it is crucial to closely follow liver function tests and viral load during the first months of transplant, and to pay a special attention in slowly tapering the immunosuppression in these patients. Lamivudine reduces HBv viremia, but favors the emergence of HBv polymerase gene mutants and should be individually discussed. Both in case of HBv or HCv hepatitis reactivation with ALT > 10N concomitantly to an increase in viral load at time of immune reconstitution, steroids should be given. In case there is no alternative than a HBv or HCv positive geno-identical donor, the risk of viral hepatitis, including acute liver failure and late complications, should be balanced with the benefit of transplant in a given situation.

Abstract: the seasonal variability of sea surface temperature (sst) in the magdalena-almejas bay lagoon system (mexico) and adjacent oceanic region was characterized in terms of the averaged monthly sst distributions obtained from avhrr satellite images during the period 1996-2001. additionally, oceanographic data obtained during five sampling campaigns were analyzed. a regional subdivision of the study area was made in relation to the main physical processes affecting the thermohaline structure, such as upwelling, tidal transport, and surface heat fluxes. annual cycles of monthly mean sst for these subregions showed that during the period from april to september the inner lagoon water was warmer than the adjacent oceanic water, with a maximum difference of 1.3°c in june. during the period from october to february, the sst inside the lagoon system was lower than in the adjacent ocean (by up to -1.5°c in december). these results are discussed in terms of upwelling activity in the adjacent oceanic region and winter cooling effects on the surface, particularly in almejas bay. most of the system (about 70% of its surface) is characterized by vertical homogeneity. thermohaline stratification modulated by coastal upwelling activity in the adjacent oceanic region is observed in the deepest part of the lagoon system (>15 m), especially during the spring and summer. the oceanic conditions frequently observed in this subregion of magdalena bay are hypothetically explained by the combined action of coastal upwelling and horizontal tidal transport. these local effects were more evident during the flood, when a strong tidal flow (up to 1.1 m s-1) produced intense vertical mixing of near-bottom cold water with upper layer water leading to reduced sst values.
An ArcGIS Geo-Morphological Approach for Snow Avalanche Zoning and Risk Estimation in the Province of Bergamo  [PDF]
Barbara Marana
Journal of Geographic Information System (JGIS) , 2017, DOI: 10.4236/jgis.2017.92006
Abstract: This paper describes the results of a study developed, with a GIS approach, at the University of Bergamo, about snow avalanche zoning and risk assessment in the Province of Bergamo. The adoption of a simplified estimation model, presented here, nonetheless allowed achieving results in good accordance with those provided by previous, more rigorous studies at the Province of Bergamo. A following analysis has also been performed to estimate ski lifts, urban areas, power lines, highways, railroads and roads at possible risk. This is a work in progress, since further development has already been taken into account to enrich the risk model with more parameters describing land morphology and meteorology. These results will then be used to simulate accidents and to estimate the shortest routes for rescuers. Finally, the development of a geo-app for mobile devices could become a very useful and fast tool for avalanche risk areas information.
A Simplified ArcGIS Approach for Landslides Risk Assessment in the Province of Bergamo  [PDF]
Barbara Marana
Journal of Geographic Information System (JGIS) , 2017, DOI: 10.4236/jgis.2017.96044
Abstract: The paper describes a simplified GIS approach, for landslides risk assessment in the Province of Bergamo, developed for a GIS degree thesis at the faculty of Engineering of the University of Bergamo. The subject has been and still is largely studied by many researchers with the aid of rigorous mathematical/statistical analysis tools. This work follows some procedures carried out by other studies, but at the end it has been decided to adopt a simple, fast and not rigorous way to find a solution. A following analysis, on the higher risk areas identified, has also been performed to test their reliability, allowing achieving satisfactory results. It has been planned to study the risk model more thoroughly, by taking into account other triggering causes for landslide susceptibility and to try also a rigorous approach, so as to get a better idea of the results achieved so far and how to improve them.
A Green GIS Solution against Air Pollution in the Province of Bergamo: The Paulownia Tree  [PDF]
Barbara Marana
Journal of Geographic Information System (JGIS) , 2018, DOI: 10.4236/jgis.2018.102010
Abstract: The paper describes a GIS approach to identify the most suitable areas for growing the Paulownia tree in the Province of Bergamo; this work will become the subject of a dissertation thesis at the School of Engineering of the University of Bergamo. Paulownia is quite an ancient tree, well known especially in the far east countries, for its wonderful flowers and the quality of the wood which is a source of certain profit. The paper is focused on the employment of the Paulownia tree against air pollution, since its big leaves absorb high amounts of CO2 in the atmosphere and can capture the small particles of pollutants in the air ten times more than any other tree species. First, the analysis identifies the most favourable areas for its growth in the Province of Bergamo. Secondly, among the latter, the analysis detects the strategic areas for its growth near the most polluted zones. Finally, a quantitative evaluation is carried out about the trees contribution against pollutants in the atmosphere.
A GIS Pre and Post Processing Contribution to a Multi Techniques Test Survey for an Ancient Railway Restoration in the Brembana Valley  [PDF]
Barbara Marana
Journal of Geographic Information System (JGIS) , 2018, DOI: 10.4236/jgis.2018.105031
Abstract: Stemming from the renewed desire to requalify the former Brembana Valley railway route (inside one of the valleys of the Province of Bergamo and close to the important city of Milan), from Bergamo to Villa d’Almè, in 2017, the Bergamo Transport Company and other partners have signed a memorandum of understanding. They have also entrusted a project company to develop a technical and economic viability study, which would be an update of a preliminary one presented in 2009. A private proposal for the realization of a test survey, useful for the required engineering project, has been submitted to the project company and accepted. For this reason, a team, comprising different companies, and among them also the Geomatics group at the University of Bergamo, was formed so as to perform this task and develop it in a degree thesis. The aim of the test survey is to evaluate a joint use of the new available technologies, so as to possibly get faster, more economic and thorough results, by performing a 3D metric analysis over two sub-areas selected along the route. The paper describes this experience and the achieved results. In particular, the areas of interest in the test project have been analyzed first thing with a GIS software and then surveyed with a multi-sensor approach, i.e. terrestrial laser scanner, GNSS techniques and UAV. The final integrated results allowed providing a metric model of the morphological and urban aspect for the territorial layout, useful also for further advanced GIS analyses. The analysis of the reached precisions has provided satisfactory results which agree with the metric requirements of the project. Further meaningful considerations can be derived from this test survey: the implementation of different techniques has helped to overcome problems due to hidden parts in complex objects, it has allowed to provide a faster survey and to test different technologies and software packages. The results have been quite satisfactory.
Geometric Instruments for the Orientation and Measurement: The Astrolabes  [PDF]
Barbara Aterini
Advances in Historical Studies (AHS) , 2019, DOI: 10.4236/ahs.2019.81004
Abstract: The astrolabe, stereographic projection of the celestial sphere on the plane of the equator, simulates the apparent rotation of this sphere around the Earth, with respect to a certain latitude, and allows to establish the relative position of the stars at a given moment. To understand its meaning and use it is necessary to recall out the main elements of astronomical geography. From the III century BC onwards, various types of astrolabe were built. Among the tools used in the course of the centuries for orientation and measurement, it is the one that perfectly performed both functions, providing measurements related to different fields of investigation: astronomy, chronometry, orientation, measurements (length-height-depth), astrology.
Eliciting Guilty Feelings: A Preliminary Study Differentiating Deontological and Altruistic Guilt  [PDF]
Barbara Basile, Francesco Mancini
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.22016
Abstract: Guilt has been identified as both an intrapsychic and an interpersonal emotion. The current study presents evidence of the existence of two senses of guilt, deontological and altruistic guilt, induced through different experimental paradigms. Deontological guilt evolves from having slighted moral authority or norms, while altruistic guilt arises from selfish behavior and the distress of others. We hypothesize that specific stimuli would evoke, separately, deontological guilt and altruistic/interpersonal guilt feelings. Two different procedures were used to test our hypothesis, adding two emotions as control conditions (i.e. anger and sadness). Results clearly indicate that two different guilt emotions can be evoked separately, by appropriate stimulation. Findings and possible clinical implications are discussed.
A Case Study of Gut Fermentation Syndrome (Auto-Brewery) with Saccharomyces cerevisiae as the Causative Organism  [PDF]
Barbara Cordell, Justin McCarthy
International Journal of Clinical Medicine (IJCM) , 2013, DOI: 10.4236/ijcm.2013.47054

Gut Fermentation Syndrome also known as Auto-Brewery Syndrome is a relatively unknown phenomenon in modern medicine. Very few articles have been written on the syndrome and most of them are anecdotal. This article presents a case study of a 61 years old male with a well documented case of Gut Fermentation Syndrome verified with glucose and carbohydrate challenges. Stool cultures demonstrated the causative organism as Saccharomyces cerevisiae. The patient was treated with antifungals and a low carbohydrate diet and the syndrome resolved. Helicobacter pylori was also found and could have been a possible confounding variable although the symptoms resolved post-treatment of the S. cerevisiae.

Early Childhood Teacher Preparation: Using the Co-Teaching Model  [PDF]
Barbara F. Hartigan
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.58076

Previous research shows that co-teaching during the student teaching practicum should be the model used by colleges and universities. This researcher used an open-ended questionnaire, a Likert-type scale survey, and individual conferences to ascertain teacher candidates’, cooperating teachers’, and university supervisors’ perceptions of the co-teaching model’s benefits, or lack thereof. The twenty-nine student teachers surveyed represent a private university and earned degrees in early childhood special education. The teacher candidates, cooperating teachers, and university supervisors are hired by the university and are experts in the aforementioned field of education. Findings reveal that pre-teacher candidates, university supervisors, and cooperating teachers all believe that mentoring during student teaching using the co-teaching model is beneficial for both the pre-teacher candidates and students in the classroom if proper professional development is offered and continuous and ongoing reflection and planning take place.
