La fracture numérique s’est déplacée des équipements aux usages et les bibliothèques en tant que lien social pour les plus démunis, conscientes de ce problème, jouent leur rôle de médiateur dans ce domaine. Cet ouvrage, sous la direction de Pascal Plantard, enseignant-chercheur à l’université de Rennes 2, spécialiste de l’exclusion numérique et Agnès Vigué-Camus, chargée d’études en sociologie à la Bibliothèque publique d’information (BPI), présente les ateliers internet comme des solutions p..

Validation Of A HACCP Program For The Production Of Artisan Fermented Dry Cured Pork Products

University of Minnesota M.S. thesis. November 2015. Major: Food Science. Advisor: Joellen Feirtag. 1 computer file (PDF); viii, 100 pages.Artisan-style pork salami batter and whole muscles were inoculated with ca. 7.0 log CFU/g of Enterococcus faecium. Salami were fermented to a pH ≤5.3 and aged to a water activity ≤0.91 and whole muscles were aged to a water activity ≤0.91 in accordance with the HACCP plan. Samples were taken at each processing step, and microbiological and physiochemical analysis were performed. End-product testing was performed by third parties. The specific processes applied demonstrated approximately 3 log10 CFU/g reduction in small caliber salami and 5 log10 CFU/g reductions in large caliber salami and whole muscle products. These results demonstrated that the process met the CCPs and validated the HACCP plan. The plan was accepted by FSIS, USDA

Annabelle Klein, dir., Nos jeunes à l’ère numérique

À l’heure où beaucoup de questions se posent sur les rapports des jeunes et du numérique, cet ouvrage essaie de donner des clés aux éducateurs pour les accompagner. Coordonné par Annabelle Klein, spécialiste des questions d’identité numérique, il propose un regard centré sur les « pratiques jeunes » et la place occupée par les écrans dans leur environnement. Sa composition – plusieurs contributions d’auteurs issus de disciplines différentes : philosophie, psychologie, sciences de l’informatio..

Time-Optimal Gate-Traversing Planner for Autonomous Drone Racing

In drone racing, the time-minimum trajectory is affected by the drone's capabilities, the layout of the race track, and the configurations of the gates (e.g., their shapes and sizes). However, previous studies neglect the configuration of the gates, simply rendering drone racing a waypoint-passing task. This formulation often leads to a conservative choice of paths through the gates, as the spatial potential of the gates is not fully utilized. To address this issue, we present a time-optimal planner that can faithfully model gate constraints with various configurations and thereby generate a more time-efficient trajectory while considering the single-rotor-thrust limits. Our approach excels in computational efficiency which only takes a few seconds to compute the full state and control trajectories of the drone through tracks with dozens of different gates. Extensive simulations and experiments confirm the effectiveness of the proposed methodology, showing that the lap time can be further reduced by taking into account the gate's configuration. We validate our planner in real-world flights and demonstrate super-extreme flight trajectory through race tracks

Presentations of perforated colonic pathology in patients with polymyalgia rheumatica: two case reports

<p>Abstract</p> <p>Introduction</p> <p>Polymyalgia rheumatica is an increasingly common disease in older people, which gives rise to arthralgia and is mainly treated with corticosteroids. Patients in this age group also have a higher incidence of other co-morbidities including colonic pathology. Corticosteroid usage may mask signs of sepsis or complications secondary to intra-abdominal pathology, thereby delaying diagnosis and treatment, with eventual adverse outcome. These two cases highlight the importance of awareness and prompt recognition of this condition in order to avoid significant morbidity and mortality.</p> <p>Case presentation</p> <p>Case 1</p> <p>A 73-year-old Caucasian woman with a diagnosis of polymyalgia presented with symptoms of an exacerbation in her right hip joint. Despite standard therapy with corticosteroids she failed to improve and started to develop features of widespread sepsis. Specific questioning revealed that, at the very onset of her symptoms, she had experienced mild diarrheal symptoms. Investigations revealed perforated diverticular disease with a peri-femoral abscess.</p> <p>Case 2</p> <p>A 69-year-old Caucasian woman with polymyalgia presented with left thigh pain and weakness associated with weight loss. A diagnosis of exacerbation of polymyalgia rheumatica was made and she was treated with corticosteroid therapy. Shortly afterwards she was admitted with generalized peritonitis. Laparotomy revealed a retroperitoneal abscess secondary to a perforated sigmoid colonic tumor.</p> <p>Conclusions</p> <p>Patients with polymyalgia may have perforated colonic diverticular disease which mimics their rheumatic pathology. In such cases steroid therapy, which is the mainstay of polymyalgia therapy, can be detrimental. Primary and hospital practitioners are encouraged to be vigilant regarding non-specific gastrointestinal symptoms and consider alternative diagnoses in those patients whose symptoms do not resolve with standard therapy, as this can lead to an overall better outcome.</p

LP 349-25: a new tight M8V binary

We present the discovery of a tight M8V binary, with a separation of only 1.2 astronomical units, obtained with the PUEO and NACO adaptive optics systems, respectively at the CFHT and VLT telescopes. The estimated period of LP 349-25 is approximately 5 years, and this makes it an excellent candidate for a precise mass measurement.Comment: Accepted by Astronomy and Astrophysics Letter

Classification of temporomandibular joint sounds based upon their reduced interference distribution

Temporomandibular joint (TMJ) sounds were recorded in 98 orthodontic retention patients, mean age 19 ± 8–6 (s.d.) years, by interview, auscultation and electronic recording. Sounds were found by auscultation in 41% and by interview in 32% of the subjects, more often in females than in males (P ≤ 0.05). A new method for time-frequency analysis, the reduced interference distribution (RID), was used to classify the electronic sound recordings into five subclasses, RID types 1–5, based upon location and number of their energy peaks. RID types 1–3 had a few energy peaks close in time. RID types 4–5, typical of subjects with crepitation, had multiple energy peaks occurring close in time for a period of 20–300 ms. RID type 1, found in 45% of the subjects, typical of patients with clicking, had its dominant energy peak located in a frequency range ≤600 Hz and was significantly more common in the female than in the male subjects (P≤ 0.01). RID type 2, found in 68% of the subjects, with the dominant peak in the range 600–1200 Hz, and RID type 3, found in 38% of the subjects, with the peak in the frequency range >1200 Hz, were found to have a similar gender distribution. RID type 4, found in 49% of the subjects, had the energy peaks distributed in the frequency range ≤600 Hz. RID type 5, found in 43% of the subjects, more often in females than in males (P≤ 0.05), had the peaks distributed over the whole frequency range from about 30 Hz up to about 3000 Hz. In conclusion, a more detailed classification could be made of the TMJ sounds by displaying the RIDs than by auscultation. This suggests that RID classification methods may provide a means for differentiating sounds indicating different types of pathology.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74694/1/j.1365-2842.1996.tb00809.x.pd
