Quasi-Fractional Models of Human Tendons Hereditariness
2018
In this study, the authors, after collecting a series of experimental evidences following a creep and relaxation tendon campaign, propose a non-linear model of the viscoelastic behavior of the tendons. The ligaments investigated are the patellars and the hamstrings. The analytical model proposed by the authors aims to explain the non-linear hereditary behavior of these tissues and proposes an approach with which to develop a hereditary fractional-order non-linear model.
Use of accelerometers and gyros for hip and knee angle estimation
2013
In this paper a wearable sensor system, consisting of accelerometers and gyros, has been studied to estimate hip and knee angles. The proposed algorithm, developed in order to avoid the error accumulation due to gyroscopes drift, has been tested on angle measurement of the hip and knee of a commercial device for assisted gait. The results have shown a good accuracy of the angles estimation, also in high angle rate movement
Parathyroid hormone-related peptide and 8701-BC breast cancer cell growth and invasion in vitro: evidence for growth-inhibiting and invasion-promotin…
1995
It has been previously reported that 8701-BC cells, derived from a primary carcinoma of the breast, constitutively express parathyroid hormone-related peptide (PTHrP) gene and that N-terminal PTHrP immunoreactivity can be found in cell medium. Here we have firstly measured immunoreactive PTHrP in 8701-BC cell medium using antibodies raised against midregion and C-terminal fragments, and also demonstrated the expression of PTH/PTHrP receptor by 8701-BC cells. Secondly, we have examined the role, if any, elicited by diverse PTHrP domains on 8701-BC cell proliferation, and invasive behaviour in vitro related to production of extracellular proteolytic enzymes. Our data show that PTHrP [1-34], a…
Impingement of the Sciatic Nerve due to a Protruding Acetabular Cage Rim
2020
Abstract Sciatic nerve damage is a well-known complication that occurs in 1.5% of patients after primary total hip arthroplasty and in 8% after revision total hip arthroplasty. Yet when considering re-revision arthroplasty and acetabular cage implantation, incidence and management remain unclear. This case report describes a young female patient with sciatic nerve impingement after acetabular cage implantation. Her primary complaint was shooting sciatic left leg pain, worsening on ambulation and when seated. A complete workup was negative for spinal impingement or infection, and axonal nerve damage was confirmed through nerve conduction studies. The intraoperative findings showed that it wa…
The Epidemiology of Hip and Knee Primary and Revision Arthroplasties during the COVID-19 Pandemic
2021
Background: The purpose of this study was to provide a comprehensive assessment of the impact of the COVID-19 pandemic on the epidemiology of primary and revision arthroplasties of the hip and knee joint. Methods: This study compared the data on knee and hip arthroplasty procedures from 2 hospitals (primary and revision) conducted in two periods: the period of the COVID-19 pandemic in Poland (from 4 March 2020 to 15 October 2020) and the corresponding period prior to the pandemic (from 4 March 2019 to 15 October 2019). We compared the epidemiological data, demographic data, and hospital stay duration data from these two periods. Results: Our analysis demonstrated that the total number of hi…
Legal nature of the Supreme Court resolutions
2020
Przedmiotem opracowania jest charakter prawny uchwał Sądu Najwyższego. Charakter ten jest sporny w doktrynie. W tym zakresie występują trzy odmienne stanowiska. Według jednego z nich „uchwały Sądu Najwyższego są orzeczeniami”. Drugie stanowisko przyjmuje, iż „uchwały Sądu Najwyższego stanowią odrębną grupę orzeczeń, nie są jednak orzeczeniami sądu, które dotyczą przedmiotu procesu, ponieważ nie rozstrzygają wprost o jego przedmiocie”. Trzeci kierunek głosi, że „uchwały Sądu Najwyższego, wydawane na podstawie art. 441 § 1 k.p.k., rozstrzygające zagadnienia prawne, nie należą do kategorii orzeczeń”. Przeprowadzone rozważania w niniejszym artykule prowadzą zatem do konkluzji, że uchwały Sądu N…
La pierre et les hommes en Bourgogne. Archéologie et histoire d'une ressource en œuvre du Moyen Âge à l'Époque Moderne
2014
In order to go further limits inherent to subject disjunction, or those imposed by sources, periods or sites, this thesis emphasises a multidisciplinary and diachronic approach of stone supply on medieval and modern building sites. Thanks to the confrontation of buildings with different origins and functions, this work tries to dissect process of choices and stone supply network. It finally considers connection between people and a natural ressource.
A Navigation and Augmented Reality System for Visually Impaired People
2021
In recent years, we have assisted with an impressive advance in augmented reality systems and computer vision algorithms, based on image processing and artificial intelligence. Thanks to these technologies, mainstream smartphones are able to estimate their own motion in 3D space with high accuracy. In this paper, we exploit such technologies to support the autonomous mobility of people with visual disabilities, identifying pre-defined virtual paths and providing context information, reducing the distance between the digital and real worlds. In particular, we present ARIANNA+, an extension of ARIANNA, a system explicitly designed for visually impaired people for indoor and outdoor localizati…
The Sanremo-Effect. Exposing Rape, Normalizing Sexism.
2021
Le Festival de la chanson de Sanremo est l’un des événements médiatique plus importants d’Italie. L’édition 2020, centrée sur le thème de la violence faite aux femmes, s’est déroulée sous le feu d’une controverse qui a conduit présentateurs et spectateurs a se questionner en direct sur la « vraie » violence. Notre objectif est de comprendre ce que les normes du genre télévisuel font à la mise en discours de la violence de genre. Le résultat est paradoxal : on aboutit à normaliser le sexisme tout en dénonçant le viol. Pour mettre en perspective cet « effet-Sanremo » par rapport au débat sur la « culture du viol », on propose une cartographie des tropes qui ont structuré le discours du specta…
