The late Byzantine and early Ottoman Trikala of Thessaly

Η σύνθεση των δεδομένων του οθωμανικού καταστίχου BBA/MM 10 με τα στοιχεία των πηγών της υστεροβυζαντινής περιόδου, αποκαλύπτει τη συνέχεια στις λειτουργίες της πόλης των Τρικάλων ως εξέχοντος διοικητικού και εμπορικού κέντρου, ενώ το αγροτικό σκέλος της οικονομίας της πόλεως είχε ενδεχομένως περιοριστεί. Η βασική διαφοροποίηση έχει να κάνει με την ισχυρή, και πλειοψηφική ήδη από τα μέσα του 15ου αιώνα, παρουσία του μουσουλμανικού στοιχείου, που αλλάζει σε σημαντικό βαθμό την φυσιογνωμία της πόλη

A canonical ideal approach to the deformation theory of curves with automorphisms and an application to the local lifting problem

The deformation theory of curves is studied by using the canonical ideal. The problem of lifting curves with automorphisms is reduced to a lifting problem of linear representations. As an application we prove that the dihedral group $D_{p^h}$ of order $2p^h$ is a local Oort group.Comment: 39 page

A new obstruction to the local lifting problem

We study the local lifting problem of actions of semidirect products of a cyclic $p$-group by a cyclic prime to $p$ group, where $p$ is the characteristic of the special fibre. We give a criterion based on Harbater-Katz-Gabber compactification of local actions, which allows us to decide whether a local action lifts or not. In particular for the case of dihedral group we give an example of dihedral local action that can not lift and in this way we give a stronger obstruction than the KGB-obstruction.Comment: 21 page

Deformation Theory

Στην παρούσα διπλωματική θα ασχοληθούμε με την θεωρία παραμορφώσεων, όπως διαμορφώθηκε στην γλώσσα των schemes, από τον Grothendieck. Πιο συγκεκριμένα θα ακολουθήσουμε την δημοσίευση του Schlessinger (Functors of Aritn rings), στην οποία αποδεικνύει ένα εύχρηστο κριτήριο αναπαραστασιμότητας.We will give an introduction to Deformation Theory, as was formalized and translated into the language of schemes by Grothendieck. More precisely we will follow the paper of Schlessinger (Functors of Artin rings), in which he proved a useful criterion about pro-representability

ACR Appropriateness Criteria® Hodgkin Lymphoma-Favorable Prognosis Stage I and II

This topic addresses the treatment of newly diagnosed patients with favorable prognosis stage I and II Hodgkin lymphoma. In most cases, combined modality therapy (chemotherapy followed by involved site radiation therapy) constitutes the current standard of care. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. By combining the most recent medical literature and expert opinion, this revised guideline can aid clinicians in the appropriate use of combined modality therapy for favorable prognosis stage I and II Hodgkin lymphoma. Increasing information about the late effects of treatment has led to attempts to decrease toxicity by using less chemotherapy (decreased duration and/or intensity or different agents) and less radiation therapy (reduced volume and/or dose) while maintaining excellent efficacy

Oral Health Status of Patients with Mental Disorders in Southwest Ethiopia

BACKGROUND: Psychiatric disorders are known to be a risk factor for the development of different oral health problems especially for dental caries and periodontal diseases. In spite of this fact, no study has been conducted to reveal its magnitude in Ethiopia. Hence, this study was conducted to determine the oral health status of psychiatric patients at Jimma University Specialized Hospital (JUSH), Psychiatric Clinic. METHODS: A hospital based cross- sectional study was used from January to May 2011. A total of 240 participants were included in the study. Dental examination was done to measure indices of oral health: decayed, missing, and filled teeth (DMFT) index and community periodontal index (CPI). Oral examination was performed using mirror, probe and explorer by experienced dental doctors. A simple random sampling technique was implemented to collect data. ANOVA test, binary logistic and multinomial logistic regression analyses were done using SPSS 16.0 statistical software. RESULTS: The mean DMFT score among the psychiatric patients was 1.94 ± 2.12 (mean ± SD) with 1.28 ± 1.69, 0.51 ± 1.19 and 0.14 ± 0.48 (mean ± SD) for decayed, missed and filled teeth respectively. Only about 24% of the psychiatric patients had a healthy CPI score. Incorrect tooth brushing technique was significantly associated with a DMFT score greater than 2 (AOR = 3.58; 95% CI: 1.65, 7.79). The habit of sweet intake was also associated with dental caries (AOR = 2.91; 95% CI: 1.43, 5.95). Similarly, patients with a smoking habit also demonstrated statistically significant association with dental caries (AOR = 18.98; 95% CI: 5.06, 71.24). CONCLUSION: The oral health status of the psychiatric patients was poor. Thus, health education about oral hygiene should be given for psychiatric patients so they can avoid the frequent intake of sweets, smoking and learn correct tooth brushing technique
