Il settore dei dispositivi medici in Italia. L’impatto delle politiche pubbliche sulle performance delle imprese
No full textThe Italian medical device industry experiences a strong regulatory influence due to the predominant presence of public purchasers. During the last decade, regional governments have introduced a wide range of policies to control public expenditure and particular attention has been paid to public purchasing procedures. This study aims at analyzing the impact of the new public procurement policies on wholesalers’ performance (ROE, current ratio, collection period) starting from the analysis of two different cases: disposable devices and dental devices. Our results show that the adoption of a centralized purchasing strategy produces a decrease in wholesalers’ ROE in the short run, but this effect appears to be less evident (although still significant) in the Regions where this model has been established earlier and is more frequently adopte

Gavrikov, due to the need to study the artistic ontology of Bashlachev in a linguo-poetic perspective. The main results of the study are identified, their theoretical and historical-literary significance is stated
Today's lifestyles, tomorrow's cancers: Trends in lifestyle risk factors for cancer in low- and middle-income countries
No full textBackground: The global burden of cancer is projected to increase from 13.3 to 21.4 million incident cases between 2010 and 2030 due to demographic changes alone, dominated by a growing burden in low- and middle-income countries (LMICs). Lifestyle risk factors for cancer are also changing in these countries and may further influence this burden.Design: We consider examples of changes already occurring in population-level distributions of tobacco and alcohol consumption, body weight, and reproductive lives of women to gauge the magnitude of their projected impact on cancer incidence in future decades.Results: Trends in lifestyle factors vary greatly between settings and by sex. Some common trends point to considerable increases in cancers of the (i) lung in men due to tobacco smoking; (ii) upper aerodigestive tract (UADT) due to increasing tobacco and alcohol consumption, worse in men; (iii) colon from increasing body mass index, and alcohol and tobacco consumption; and (iv) in women, breast due particularly to consistent international trends of younger age at menarche, smaller family size, and, at postmenopausal ages, increasing body weight.Conclusions: In many LMICs, the future cancer burden will be worsened by changing lifestyles. Affected common cancer sites likely to experience the largest increases are lung, colon, UADT, and breast. © The Author 2011.

Expanding the Applicability of the Competitive Modes Conjecture
No full textThe Competitive Modes Conjecture is a relatively new approach in the field of Dynamical Systems, aiming to understand chaos in strange attractors using Resonance Theory. Up till now, the Conjecture has only been used to study multipolynomial systems because of their simplicity. As such, the study of non-multipolynomial systems is sparse, filled with ambiguity, and lacks mathematical structure. This paper strives to rectify this dilemma, providing the mathematical background needed to rigorously apply the Competitive Modes Conjecture to a certain set of non-multipolynomial systems. Afterwards, we provide an example of this new theory in the non-multipolynomial Wimol-Banlue Attractor, something that up to this point has not been possible as far as the authors know.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Numerical Analysi
The biography of G.I. Blosfeld, the author of the first handbook on forensic medicine for lawyers
No full textThe paper covers some chapters of the biography of Professor G.I. Blosfeld (1797–1884), who was a famous scientist and headed the Department of Forensic Medicine, Medical Policy, History of Medicine, Hygiene, and Toxicology of the Kazan Imperial University from 1839 to 1864. A brief description of the state of medicine, public health, and teaching of medical sciences in the Russian Empire of the late 18th and early 19th centuries has been provided. The archival data on the activities of G.I. Blosfeld in the chair, memories of his students have been presented. The achievements of G.I. Blosfeld as a researcher and lecturer, who organized forensic medicine teaching at the Law Department of the Kazan University and created the first handbook on forensic medicine for lawyers published in 1847 in Kazan. The structure of the handbook has been analyzed, as well as other works of this researcher. His role among other forensic medical examiners of that period has been demonstrated
Model improvements to simulate charging in SEM
No full textCharging of insulators is a complex phenomenon to simulate since the accuracy of the simulations is very sensitive to the interaction of electrons with matter and electric fields. In this study, we report model improvements for a previously developed Monte-Carlo simulator to more accurately simulate samples that charge. The improvements include both modelling of low energy electron scattering and charging of insulators. The new first-principle scattering models provide a more realistic charge distribution cloud in the material, and a better match between non-charging simulations and experimental results. Improvements on charging models mainly focus on redistribution of the charge carriers in the material with an induced conductivity (EBIC) and a breakdown model, leading to a smoother distribution of the charges. Combined with a more accurate tracing of low energy electrons in the electric field, we managed to reproduce the dynamically changing charging contrast due to an induced positive surface potential.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ImPhys/Charged Particle Optic
THE 50th ANNIVERSARY OF THE DEPARTMENT OF ORTHOPEDIC RHEUMATOLOGY, V.A. NASONOVA RESEARCH INSTITUTE OF RHEUMATOLOGY: RESULTS AND PROSPECTS
No full textThe paper describes basic steps in the establishment (1964) and development of orthopedic rheumatology and discusses its present-day status. The 50th anniversary of this discipline that is a component of modern rheumatology was celebrated in 2014. In connection with such a remarkable date the author sums up some results of the scientific and practical activities of the orthopedic rheumatologists of the V.A. Nasonova Research Institute of Rheumatology and considers the prospects for further research developments, the possible evolution of minimally invasive surgery (arthroscopic technology for the treatment of large and small joints), and the issues of rehabilitation in a wide range of rheumatic diseases, by applying high technology
“The Time of the Historian”: On the Book by V.A. Kitaev “Social Thought and Historical Science in Russia in 18-20th Centuries (Problems of Historiography)” (Nizhny Novgorod: Izd-vo NNGU, 2016. – 271 p.)
No full textThe book of V.A. Kitaev includes reviews of monographs and textbook, collective publications, including encyclopedias, publications of sources, historiographical articles, some of which were published in leading scientific journals in 1980-2015, and some were published for the first time. This publication is not exactly a review to V.A. Kitaev’s book, but an attempt to provide the reader with reflections on some of the problems of public thoughts and historiography highlighted by the author: the features of the professional study of history, historiographical analysis as a genre of research, methodology and terminology in modern studies on the history of social thought and historical science, the ratio of professional approach and political convictions, attitude to scientific traditions, etc. The present paper highlights the highest scientific professionalism of V.A. Kitaev, his ability and willingness to be critical not only to other people’s research, but also to his own. Despite the well-known assertion that “we do not choose the times”, we can safely say that V.A. Kitaev consciously chose the “time of the historian” and found himself in this time
