Maladie des griffes du chat et autres bartonelloses [Cat scratch disease and other human infections caused by Bartonella species].

The different Bartonella species can cause various human infections such as cat scratch disease, chronic bacteremia (homeless patient with nonspecific symptom), endocarditis, bacillary angiomatosis, peliosis, and Carrion's disease. Diagnostic approaches include serology, culture and molecular approaches. PCR is especially useful on lymph nodes biopsies from patients with cat-scratch disease and on valvular samples taken from culture-negative endocarditis. Serology exhibits a very high sensitivity in the latter situation. The treatment should be chosen according to the clinical presentation.

Cat Scratch Disease in kidney transplant receptors: is it a rare or underdiagnosed pathology?

Cat Scratch Disease (CSD) is an infectious disorder which appears after cat scratching particularly in children and adolescents. Bartonella henselae is the etiologic agent more frequently involved. There are only a few recent reports demonstrating the disease after transplantation, although the illness is not infrequent in immunologically competent people. Indeed CSD in transplant receptors has only been recently emphasized in the literature and it was concluded that fever and lymphadenopathy in patients who had been exposed to cats should prompt clinicians to maintain a suspicion for the infection. In this report CSD infecting a renal transplanted adolescent complaining of headache, blurred vision and fever, presenting a cat scratching lesion in the right arm, with a bilateral painful cervical lymphadenopathy was related. He also presented indirect immunofluorescency identifying that the two subtype's titles of Bartonella-henselae and quintana- were elevated. Treatment with doxicicline e rifampicin was introduced and the patient became asymptomatic in about 3 weeks.

Building from scratch a marketing services giant by acquisition: case study and interview with Sir Martin Sorrell, Chief Executive of WPP

Purpose – Mergers and acquisitions are among the most intensely used strategic decisions. Yet research by both academics and consulting groups suggests that many mergers and acquisitions fail to add value. On the other hand there are many companies that successfully use mergers and acquisition to grow and add shareholder value. One such company is WPP. The aim of this paper is to explore why WPP has been successful in its acquisition strategy while so many other companies fail. Design/methodology/approach – The paper draws on documentary evidence and a semi-structured interview with Sir Martin Sorrell – Chief Executive and founder of WPP. Research limitations/implications – The case study offers a unique insight into thinking of a successful acquirer and sheds light on how mergers and acquisitions are managed by WPP. However, because of its design the findings are not generalisable. Originality/value – This case study sheds light on how mergers and acquisitions can be used to create a £9 billion company from a standing start. Furthermore, very few case studies offer insight into the thinking of entrepreneurial Chief Executives who established the business, grew it to become the largest and most profitable marketing services company in the world and engineered close to 300 acquisitions.

Mechanical and tribological properties of PVD-coated cemented carbide as evaluated by a new multi-pass scratch testing method

A new test method based on multipass scratch testing has been developed for evaluating the mechanical and tribological properties of thin, hard coatings. The proposed test method uses a pin-on-disc tribometer and during testing a Rockwell C diamond stylus is used as the “pin” and loaded against the rotating coated sample. The influence of normal load on the number of cycles to coating damage is investigated and the resulting coating damage mechanisms are evaluated by posttest scanning electron microscopy. The present study presents the test method by evaluating the performance of Ti0.86Si0.14N, Ti0.34Al0.66N, and (Al0.7Cr0.3)2O3 coatings deposited by cathodic arc evaporation on cemented carbide inserts. The results show that the test method is quick, simple, and reproducible and can preferably be used to obtain relevant data concerning the fatigue, wear, chipping, and spalling characteristics of different coating-substrate composites. The test method can be used as a virtually nondestructive test and, for example, be used to evaluate the fatigue and wear resistance as well as the cohesive and adhesive interfacial strength of coated cemented carbide inserts prior to cutting tests.

Um estudo sobre a utilização do software SCRATCH como ferramenta de apoio ao ensino da disciplina de lógica de programação

Learning to program or master a programming language is not an easy task, and the base of process should by study Logic Programming, beginning to learning through the development of pseudocodes, algorithms and flowcharts, for, techniques that facilitate the construction and understanding of what you want to accomplish, to that is subsequently developed or elaborated a program. Reflecting on the learning of Logic Programming, this article presents information about software SCRATCH in relation to logic (pseudocodes), and how it provides support to the understanding of student learning in this course.

Horizon entropy from scratch

Scopo di questo lavoro di tesi è lo studio di alcune proprietà delle teorie generali della gravità in relazione alla meccanica e la termodinamica dei buchi neri. In particolare, la trattazione che seguirà ha lo scopo di fornire un percorso autoconsistente che conduca alla nozione di entropia di un orizzonte descritta in termini delle carica di Noether associata all'invarianza del funzionale d'azione, che descrive la teoria gravitazionale in considerazione, per trasformazioni di coordinate generali. Si presterà particolare attenzione ad alcune proprietà geometriche della Lagrangiana, proprietà che sono indipendenti dalla particolare forma della teoria che si sta prendendo in considerazione; trattasi cioè non di proprietà dinamiche, legate cioè alla forma delle equazioni del moto del campo gravitazionale, ma piuttosto caratteristiche proprie di qualunque varietà rappresentante uno spaziotempo curvo. Queste caratteristiche fanno sì che ogni teoria generale della gravità possieda alcune grandezze definite localmente sullo spaziotempo, in particolare una corrente di Noether e la carica ad essa associata. La forma esplicita della corrente e della carica dipende invece dalla Lagrangiana che si sceglie di adottare per descrivere il campo gravitazionale. Il lavoro di tesi sarà orientato prima a descrivere come questa corrente di Noether emerge in qualunque teoria della gravità invariante per trasformazioni generali e come essa viene esplicitata nel caso di Lagrangiane particolari, per poi identificare la carica ad essa associata come una grandezza connessa all' entropia di un orizzonte in qualunque teoria generale della gravità.
