Les événements de l’année aux congrès universels de la paix (1889-1914)
Les Congrès universels de la Paix avaient une section particulière dans laquelle on présentait un rapport relatif aux événements de l’année. Dans cet article on a voulu reconstituer l’histoire des relations internationales (de 1889 à 1914) à travers les documents des archives des Congrès universels de la Paix. La propagation des principes du pacifisme et du droit international était le point de départ. Les questions proposées n’avaient pas des limites géographiques. Les problèmes analysés touchaient tous les continents et toutes les mers : on ne se bornait pas à l’Europe ou aux pays méditerranéens, mais on discutait aussi des États-Unis, des pays de l’Afrique, de l’Extrême Orient, de l’Amérique Latine, etc. Dans cet article on a analysé les événements qui ont été le plus débattus par les pacifistes dans les Congrès universel de la Paix.A peace-report on the events of the year was presented in a special section of Universal Peace Congresses. In this article I want to reconstruct the history of international relations (from 1889 to 1914) on the basis of Universal Peace Congresses archives documentation. The starting point consisted in the propagation of the principles of pacifism and of international law. The issues suggested for the discussion regarded the entire world and concerned all the pregnant events that happened on the international political scene. The matters raised and debated concerned not only the European continent and the Mediterranean countries, but also the United States, Africa, Near and Far East, Latin America etc. This article present the analysis of the mostly debated events by the pacifist movement inside the Universal Peace Congresses
Soliton Turbulence in Shallow Water Ocean Surface Waves
We analyze shallow water wind waves in Currituck Sound, North Carolina and
experimentally confirm, for the first time, the presence of
in ocean waves. Soliton turbulence is an exotic form of nonlinear
wave motion where low frequency energy may also be viewed as a
, described theoretically by the soliton limit of the
Korteweg-deVries (KdV) equation, a
: Hence the phrase "soliton turbulence" is synonymous with "integrable
soliton turbulence." For periodic/quasiperiodic boundary conditions the
of KdV are exactly solvable by
(FGT), the basis of our data analysis. We find that large amplitude measured
wave trains near the energetic peak of a storm have low frequency power spectra
that behave as . We use the linear Fourier transform to
estimate this power law from the power spectrum and to filter
from the data. We apply FGT to determine the
and find that the low frequency region
is . The solitons have , a
, which supports our interpretation
of the data as soliton turbulence. From the
we are able to demonstrate that the solitons are

Silicone-coated non-woven polyester dressing enhances reepithelialisation in a sheep model of dermal wounds
Negative-pressure wound therapy (NPWT) also known as V.A.C. (Vacuum-assisted closure), is widely used to manage various type of wounds and accelerate healing. NPWT has so far been delivered mainly via opencell polyurethane (PU) foam or medical gauze. In this study an experimental setup of sheep wound model was used to evaluate, under NPWT conditions, the performance of a silicone-coated non-woven polyester (N-WPE) compared with PU foam and cotton hydrophilic gauze, used as reference materials. Animals were anesthetized with spontaneous breathing to create three 3 9 3 cm skin defects bilaterally; each animal received three different samples on each side (n = 6 in each experimental group) and was subjected to negative and continuous 125 mmHg pressure up to 16 days. Wound conditions after 1, 8 and 16 days of treatment with the wound dressings were evaluated based on gross and histological appearances. Skin defects treated with the silicone-coated N-WPE showed a significant decrease in wound size, an increase of re-epithelialization, collagen deposition and wound neovascularisation, and a minimal stickiness to the wound tissue, in comparison with gauze and PU foam. Taken all together these findings indicate that the silicone-coated N-WPE dressing enhances wound healing since stimulates higher granulation tissue formation and causes minor tissue trauma during dressing changes
Adherence to Medication in Older Adults as a Way to Improve Health Outcomes and Reduce Healthcare System Spending
Medications are used as the primary approach to prevent and effectively manage the chronic conditions. Non-adherence to medication is recognized as a worldwide public health problem with important implications for the management of chronic diseases, which affects every level of the population, particularly older adults due to the high number of coexisting diseases and consequent polypharmacy. Estimated rates of adherence to long-term medication regimen are of about 50%, and there is no evidence for significant changes in the past 50 years. The consequences of non-adherence include poor clinical outcomes, increased morbidity and mortality and unnecessary healthcare costs. Factors contributing to non-adherence are multifaceted and embrace those that are related to patients, to physicians and to healthcare systems. Cognitive, sensorial and functional decline, poor social support, anxiety, depression symptomatology and reduced health literacy have been linked to medication non-adherence in the elderly patients. Many interventions to improve medication adherence have been described in the study for different clinical conditions; however, most interventions seem to fail in their aims. In this chapter, a revision of the implications of poor adherence as well as its predictors and available tools to improve adherence is performed
Use of Thermography Techniques in Equines: Principles and Applications
none7noThis review of the use of thermographic technique in equines introduces the principles
upon which infrared radiation and thermoregulatory physiology are based and describes
the instrumentation used and its practical use. The advantage of this imaging technique is
that it is a noninvasive thermographic examination, both from an operational (the animal
and the operator) and health (no penetrating radiation is used) standpoint. Advantages
and disadvantages of this technique, equine applications, and physiological assessments are discussed.openVeronica, Redaelli; Domenico, Bergero; Enrica, Zucca; Francesco, Ferrucci; Leonardo Nanni Costa, ; Lorenzo, Crosta; Fabio, LuziVeronica, Redaelli; Domenico, Bergero; Enrica, Zucca; Francesco, Ferrucci; Leonardo Nanni Costa, ; Lorenzo, Crosta; Fabio, Luz
Volumetric Analysis of Fat Injection by Computerized Tomography in Orthognathic Surgery: Preliminary Report on a Novel Volumetric Analysis Process for the Quantification of Aesthetic Results
Background: Integrated approaches to orthognathic surgery should include accurate volumetric evaluation of the skull and soft tissues. In patients with dentofacial deformities, the most frequent aesthetic deficits are attributable to an underdevelopment of hard and soft tissues. Traditional osteotomic procedures often fail to guarantee a stability of soft tissues over time. For this reason, in selecting a surgical strategy, the surgeon should consider not only traditional osteotomies, but also soft-tissue improving procedures, such as lipofilling. Preoperative surgical planning systems, such as the Virtual surgical planning (VSP) protocol, are based mainly on skeletal movement prediction. Quantitative estimation of soft-tissue modifications is not part of common clinical practice. Most commonly, the evaluation of soft-tissue modifications after orthognathic procedures is instead performed by clinical qualitative means. The purpose of this study was to describe a novel computed tomography (CT)-based volumetric analysis process for the quantification of injected autologous adipose tissue in patients who have undergone simultaneous orthognathic and lipofilling procedures. Methods: This was a retrospective review of consecutive patients who underwent combined orthognathic surgery and lipofilling from June 2016 to May 2017 for malocclusion with functional and aesthetic impairments. Preoperative planning included clinical evaluation and virtual osteotomy planning according to the VSP protocol. The volume of fat to be injected was estimated clinically by comparing virtual renderings with preoperative clinical photographs. The surgical technique involved Le Fort I and sagittal split mandibular osteotomies, combined with autologous fat injection in the malar and perioral regions. Postoperative evaluation was performed with a novel imaging process based on CT image segmentation to quantify the exact volume of injected fat. Skeletal stability was also evaluated at 3 months. Results: Sixteen patients were enrolled in the study, all females, with a mean age of 24.5 years (range, 18-36 years). The mean difference between the fat tissue injected and that quantified postoperatively was 6.01 cm 3. All patients had clinically satisfactory facial convexity, with complete restoration of the cheekbone contour, at 3 months. Conclusion: This study introduces a novel CT-image based technique to quantitatively assess the contribution of injected fat to the postoperative soft-tissue volume increase after combined orthognathic surgery with autologous lipofilling. In the future, this CT-based volumetric analysis technique could be the gold standard for evaluating facial lipofilling outcomes, and for assessing clinical aesthetic outcomes based on the injected volume of fat
