REGULATORY T-CELLS IN CHRONIC LYMPHOCYTIC LEUKEMIA
Giovanni D'arena,Giovanni Rossi,Barbara Vannata,Silvia Deaglio
Mediterranean Journal of Hematology and Infectious Diseases , 2012, DOI: 10.4084/mjhid.2012.
Abstract: Regulatory T-cells (Tregs) constitute a small subset of cells that are actively involved in maintaining self-tolerance, in immune homeostasis and in antitumor immunity. They are thought to play a significant role in the progression of cancer and are generally increased in patient with chronic lymphocytic leukemia (CLL). Their number correlates with more aggressive disease status and is predictive of the time to treatment, as well. Moreover, it is now clear that dysregulation in Tregs cell frequency and/or function may result in a plethora of autoimmune diseases, including multiple sclerosis, type 1 diabetes mellitus, myasthenia gravis, systemic lupus erythematosis, autoimmune lymphoproliferative disorders, rheumatoid arthritis, and psoriasis. Efforts are made aiming to develop approaches to deplete Tregs or inhibit their function in either cancer and autoimmune disorders.
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
Abstract:

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
Abstract:

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.

Assessment and Mapping of Groundwater Vulnerability Using SAR Concentrations and GIS: A Case Study in Al-Mafraq, Jordan  [PDF]
Majed Ibrahim, Barbara Koch
Journal of Water Resource and Protection (JWARP) , 2015, DOI: 10.4236/jwarp.2015.77047
Abstract: Groundwater is the main source of water supply in Jordan. Due to lower precipitation rates in recent years, the surface water is increasingly limited. Research on groundwater vulnerability helps protect this main source of water supply and assists in the development of plans to confront the deterioration and contamination of aquifers from wastewater and agricultural activities in order to protect groundwater for future generations. The important factors to determine groundwater vulnerability are environmental conditions; hence the spatial conditions in arid to semi-arid areas must be taken into account when applying different models. The aquifer vulnerability has been assessed in Jordan by using the DRASTIC method; remote sensing and Geographic Information System (GIS) data were used to derive and process data. The DRASTIC index was used with seven parameters to describe physical characteristics of the aquifers. It is concluded that about 34% of the area was considered to be of moderate vulnerability, but the share increased to 60% after modifying the index. While high vulnerability was at 25% of the total area, it decreased to 6.3% with the modified index; therefore, urgent pollution prevention measures should be taken for every kind of relevant activity within the whole basin.
