Early Modern Persian, Urdu, and English Historiography and the Imagination of Islamic India under British Rule

This paper analyses the early modern transformations of South Asian literary cultures through the production of historiography in Persian, English, and Urdu. In the 18th-19th centuries, South Asian communities experienced and participated in a major restructuring of the languages of the subcontinent. Urdu and English were institutionalized as governmental languages and utilized in new literary productions as Persian was gradually marginalized from the centre of literary and governmental polities. Three interrelated colonial policies reshaped the historical consciousness of South Asia and Britain: the production of new Persian histories commissioned under British patronage, the initiation of Urdu historiography through the translation of Persian and English histories, and the construction of the British history of India written in English. This article explores the historical and social dynamics of these events and situates the origins and evolution of the colonial historiographical project. Major works discussed are the Tārīkh-i Bangālah of Salīm Allāh Munshī (fl. 1763), James Mill's (1773-1836) The History of British India first published in 1817, Mīr Sher ʿAlī Afsos' the Ārāʾish-i mahfil, as well as the production of original Urdu histories such as Muḥammad Zakāʾ-Allāh's (1832-1910) the Tārīkh-i Hindustān.

Courts and Courtly Cultures in Early Modern Italy and Europe: Models and Languages

This volume deals with the forms of propaganda and self-representation, through words and images, during the rise of the 'civiltà delle corti' and through processes typical of the time, such as confrontation, adaptation, competition and rivalry. This period, which marked the passage of Italian and European culture from the Middle Ages to the Renaissance, is fundamental in the development of Modern Europe, and it lasted up to the XVIII century and beyond. At the heart of many matters debated here lies the relationship between culture and politics. The formation of a 'Lombard identity', central to the Sinergia project which was the frame of the whole research and its conferences, is closely linked to this broad general context. It places the so called 'questione milanese' - above the traditional hierarchies 'Toscana oriented' - at the centre of many questions regarding Northern Italy as a whole, starting from the dissolution of the Medieval communes, through to the rise of the signorie, from the end of the XIII century and the beginning of the XIV century up to the early XVI century.

Le reflux gastro-oesophagien de l'enfant: indications chirurgicales, techniques et suivi.

Contexte: Présent sous forme physiologique chez environ 60% des nourrissons normaux de moins de quatre mois, le reflux gastro-oesophagien (RGO) n'est symptomatique que chez 10% d'entre eux. Il est également plus fréquent chez les enfants atteints de troubles neurologiques quelque soit leur âge. Non traité, il peut avoir des conséquences graves (oesophagite, sténose peptique, endobrachyoesophage (Barrett) puis adénocarcinome de l'oesophage). Il s'agit donc d'un problème qu'il faut savoir détecter et traiter précocement. Les signes et symptômes du RGO sont multiples et varient en fonction de l'âge. Ils ne se limitent pas au seul vomissement. Le traitement initial du RGO chez l'enfant est médical. En cas d'échec de celui-ci ou dans certaines indications (comme les RGO récidivants, les malformations congénitales, les anomalies morphologiques ou les pathologies neurologiques) un traitement chirurgical est nécessaire. L'évolution des traitements conservateurs et des techniques chirurgicales lors de ces dernières années en font un bon sujet pour une étude rétrospective. Objectif: Le but de cette étude est de mettre en évidence dans une population d'enfants ayant bénéficié d'une cure chirurgicale anti-reflux la fréquence relative des symptômes selon la pathologie initiale de l'enfant, puis de préciser le choix de traitement et sa durée. Nous analyserons également les risques d'échec qui s'y rapportent. Ces conclusions devraient nous permettre de proposer un algorithme décisionnel de prise en charge du RGO de l'enfant en pré et post-opératoire. Méthodologie: Étude rétrospective sur 9 ans se basant sur les dossiers médicaux-chirurgicaux de 132 enfants opérés d'un reflux gastro-oesophagien dans le Service de Chirurgie Pédiatrique du Centre Hospitalier Universitaire Vaudois (CHUV) par le Professeur Olivier Reinberg et son équipe entre le 1er janvier 2003 et le 31 décembre 2012. Résultats: Sur les 132 enfants, 93 ont bénéficié d'une fundoplicature selon Toupet, 34 selon Nissen et 5 selon Dor. 57% des enfants présentant un déficit neurologique ont été opérés selon la technique de Nissen contre 7% des enfants "sains". Les taux de démontage et de récidive sont respectivement 5.4% et 3.5 % pour la technique selon Toupet et 2.9% et 0% pour la technique de Nissen. Le taux de démontage global de la fundoplicature est de 4.6% (N=6) Conclusions: La fundoplicature est une méthode de choix pour les enfants chez qui tous les autres traitements ont échoué ou chez qui la présence concomitante du RGO et des comorbidités est délétère à une croissance harmonieuse. Grâce à la chirurgie, la qualité de vie d'au moins 95% des enfants est grandement améliorée après la disparition de symptômes quotidiens et qui peuvent donner lieu à des complications graves.

Uma introdução à análise exploratória de dados multivariados

The modern technological ability to handle large amounts of information confronts the chemist with the necessity to re-evaluate the statistical tools he routinely uses. Multivariate statistics furnishes theoretical bases for analyzing systems involving large numbers of variables. The mathematical calculations required for these systems are no longer an obstacle due to the existence of statistical packages that furnish multivariate analysis options. Here basic concepts of two multivariate statistical techniques, principal component and hierarchical cluster analysis that have received broad acceptance for treating chemical data are discussed.

Effects of modern variable frequency drive on the reliability of an old crane induction motor

The work aims to analyze the possibilities of utilizing old crane driving AC induction motors in modern pulse-width-modulated variable frequency drives. Bearing currents and voltage stresses are the two main problems associated with modern IGBT inverters, and they may cause premature failure of an old induction motor. The origins of these two problems are studied. An analysis of the mechanism of bearing failure is proposed. Certain types of bearing currents are considered in detail. The most effective and economical means are chosen for bearing currents mitigation. Transient phenomena of cables and mechanism of over voltages occurring at motor terminals are studied in the work. The weakest places of the stator winding insulation system are shown and recommendations are given considering the mitigation of voltage stresses. Only the most appropriate and cost effective preventative methods are chosen for old motor drives. Rewinding of old motors is also considered.

The Pelosi-type versus the modified Misgav-Ladach: a randomized trial of two surgical techniques for cesarean section

Cesarean section (CS) is now the most common major surgical procedure performed on women worldwide. A quarter of deliveries in Spain are performed by cesarean section. With the increasing rates of the operation, there is the need to use evidence-based techniques to optimize outcomes and minimize complications. The goal of this study is to employ a well-designed randomized controlled trial to evaluate the intraoperative blood loss of two surgical techniques for cesarean section, the Pelosi-type and the modified Misgav-Ladach. The trial will take place in Hospital Universitari de Girona Dr. Josep Trueta From 2014 to 2015, 512 pregnant women undergoing delivery by their first lower segment cesarean section in this center will be selected through a consecutive nonprobability sampling. We will collect the main obstetrical characteristics, intraoperative outcomes, short-term outcomes for the baby and postoperative outcomes. We will evaluate the intraoperative blood loss by comparing the changes in hemoglobin levels, pre and postoperatively. Patients will be followed during the postoperative period and in a two-week postoperative appointment. We will analyze the continuous variables, such as the differences in hemoglobin levels, using an unpaired two-sided Student’s t-test, while for the categorical variables Fischer’s exact test will be used

Efeito da substituição por átomos de flúor no equilíbrio conformacional de chalcona

Chalcone (1) and its fluorinated derivatives 2-4, as well as their cyclic analogues 5-10, were synthesized through an aldol condensation reaction between the corresponding ketone and aldehyde. These compounds were characterized by IR, EIMS and ¹H and 13C NMR spectral data. Modern NMR techniques allowed us to conclude that the compounds obtained show E configuration. These techniques were also employed to investigate the equilibrium involving the s-cis and s-trans conformations of 1-4, with this equilibrium being dependent on the fluorine substitution on both aromatic rings, A or B. IR studies indicated that the yield of the s-cis conformation in the fluorinated derivatives is 57.4±1.4; 88.1±0.4 and 66.4±0.7%, for 2, 3 and 4, respectively, based on previous ¹H NMR calculations for chalcone. Theoretical calculations, using the MMX method, were employed to justify the variation of chemical shifts for the fluorinated derivatives and cyclic analogues. These chemical shifts are consequence of the anisotropic effect showed by the carbonyl group on these compounds.

Overvoltage Mitigation Techniques in Wind Power Generators

Advancements in power electronic semiconductor switching devices have lead to significantly faster switching times. In motor and generator applications, the fast switching times of pulse width modulated (PWM) inverters lead to overvoltages caused by voltage reflections with shorter and shorter cables. These excessive overvoltages may lead to a failure of the electrical machine in a matter of months. In this thesis, the causes behind the overvoltage phenomenon as well as its different mitigation techniques are studied. The most suitable techniques for mitigating the overvoltage phenomenon in wind power generator applications are chosen based on both simulations and actual measurements performed on a prototype. An RC filter at the terminals of the electrical machine and an inverter output filter designed to reduce the rise and fall times of voltage pulses are presented as a solution to the overvoltage problem. The performance and losses of both filter types are analysed.
