Kyste hydatique pancréatique: à propos d’un cas

La localisation pancréatique du kyste hydatique est rare, même dans les pays ou la maladie hydatique sévit à l'état endémique. Il ne représentant que moins de 1% de l'ensemble des localisations .La symptomatologie souvent insidieuse après une longue évolution, dépend du siège du kyste hydatique, ce qui peut expliquer les difficultés du diagnostic, prêtant à confusion avec les autres lésions kystiques du pancréas. Elle touche exceptionnellement l'enfant. Nous rapportons une observation survenue chez une patiente de 20 ans, victime il y'a 3 ans d'un traumatisme fermé de l'abdomen, qui présentait depuis 2 mois des épigastralgies isolées, avec ictère. A travers cette observation et une revue de la littérature, nous discutons les difficultés diagnostiques et les modalités du traitement chirurgical de cette localisation inhabituelle de la maladie hydatique

Stacking Simulations for Compton Positron sources of Future Linear Colliders

The Compton positron source of a future linear collider must obtain the target bunch population by accumulating a large number of positron packets, arriving either in a number of bursts from a ‘Compton ring’, with intermediate damping of the scattering electron beam, or quasicontinually from a ‘Compton energy recovery linac’. We present simulation results for the longitudinal stacking of Compton positrons in the ILC damping ring (DR) and the CLIC pre-damping ring (PDR), discussing parameter optimization, stacking efficiency, possible further improvements, and outstanding questions

Oil quality and aroma composition of 'Chemlali' olive trees (Olea europaea L.) under three irrigation regimes

The present work focused on the chemical composition of monovarietal virgin olive oil from the cultivar Chemlali cultivated in the South of Tunisia: sub-arid zone under three different irrigation regimes: stressed, moderate and well irrigation treatment with the restitution of 50, 75 and 100% of crop evapotranspiration (ETc), respectively. Quality characteristics (acidity and peroxide value) and chemical data (antioxidant compound, fatty acids volatile compounds and oxidative stability) were studied in addition to the pomological characteristic of olive fruit. Results show that there were significant differences observed in oil composition according to the irrigation regime applied. Total phenols, bitterness intensity and LOX products content showed the highest values for low irrigation regime, whereas polyunsaturated fatty acid and oxidative susceptibility values had highest values for olive oil from well irrigated trees. Analytic characteristic of fruits showed the highest values of pulp/stone ratios from olive trees irrigated by the highest amount of wate

ERL Scheme for Compton Polarised Positron Sources

International audienceOne of the main challenges for the future linear colliders projects (ILC and CLIC) is to design an efficient positron source taking into account the constraints imposed by the target heating. At present, different schemes have been analysed to produce high energy gammas and to convert them in an amorphous target. One of them considers the possibility to boost the energy of the backscattered photons of a laser pulse by Compton effect. This method is very attractive since the source is independent from the main Linac and since the photon helicity is conserved in Compton scattering and subsequently transferred to the produced pairs. This allows the physics experiments disposing of both positron and electron polarised sources. Different schemes have been proposed to provide the electron beam for the Compton collisions. taking into account the constraint imposed by the low value of the Thomson cross section. One of the explored possibilities is to design an ERL with relatively low repetition frequency, high charge per pulse and then to stack the produced positrons in an accumulation ring. Different considerations on this scheme will be illustrated and the main constraints discussed. MO6RFP06

LE PROLAPSUS RECTAL DE L'ADULTE

The rectal prolapse is the result of the anus, rectum, over its entire circumference. It is a rare disease in our context. It is said Mucosal or incomplete when it concerns the mucosa . It is a total prolapse or complete if it is all tunics. There are two clinical forms: prolapse of the young men that is rare and primitive injury occurring intermittently during the effort on a solid outdated prolapse of older women who often secondary toÊ permanent injuries acquired. The diagnosis is easy but it is important to take stock keeper, causative anatomical and functional. Complications are rare kind of strange or ulceration of the mucosa. Surgery is the only definitive treatment.Le prolapsus rectal est l'issue par l'anus, du rectum, sur toute sa circonférence. C'est une pathologie peu fréquente dans notre contexte. Il est dit muqueux ou incomplet lorsqu'il ne concerne que la muqueuse. C'est un prolapsus total ou complet s'il s'agit de toutes les tuniques. On distingue deux formes cliniques : Le prolapsus du jeune masculin qui est rare ; lésion primitive et intermittente survenant lors de l'effort sur un périmé solide Le prolapsus de la femme âgée qui est fréquent permanent secondaire à des lésions acquises. Le diagnostic est facile mais il importe de faire un bilan soigneur, étiologique anatomique et fonctionnel. Les complications sont rares à type d'étrangement ou d'ulcération de la muqueuse. La chirurgie  est le seul traitement définitif
