Abstract: A process of manufacturing a soft or semi-soft fibrous cheese comprising the steps of a) pasteurizing milk; b) acidifying the milk; c) coagulating the milk to obtain curd and whey; d) cutting the coagulum and draining the whey, thereby leaving a cheese curd; e) heating, kneading, and stretching the curd (e.g., in mixer/cooker) (1) until it is a homogeneous, fibrous mass of cheese;  f) forming the cheese into a shape (e.g., by pumping it through extruder (8));  g) cooling the shaped cheese in cold brine (e.g., in brine tanks (11 and 15));  and h) removing the cooled cheese from the brine (e.g., by conveyor (16)). A  cheese additive is mixed into the heated cheese (for example in additional mixer (6)) after the cheese has been heated, kneaded, and stretched, but before it has been formed into a shape. The additive can be an emulsifying agent, gum, stabilizer, colorant, dairy solid, cheese powder, or food starch.

Abstract: La présente invention concerne un ensemble polyaxial de verrouillage comprenant une vis et une plaque, destiné à immobiliser des os par fixation dans ceux-ci. Dans un mode de réalisation, l'invention comprend une plaque (100a) présentant des trous traversants axialement coniques (110a) dans lesquels on peut placer des vis à os (120) qui ont des têtes semi-sphériques (122) montées de façon à pouvoir tourner librement dans les volumes intérieurs d'éléments de couplage axialement coniques (132). Les vis à os (120) peuvent être introduites sous des angles variés qui permettent encore aux éléments de couplage (132) d'être logés à l'intérieur des trous (110a). Les trous (110a) et les éléments de couplage (132) peuvent être lisses ou taraudés. Les trous peuvent être allongés, de telle sorte que, pendant l'insertion, les éléments de couplage (132) se déplacent le long du trou (110a) pour donner une compression dynamique à l'os. Dans un autre mode de réalisation, les trous (110b) peuvent être en partie taraudés et en partie coniques, de telle sorte qu'on peut utiliser un élément de couplage en deux parties. Dans un autre mode de réalisation, encore, l'élément de couplage peut comprendre une partie en forme de bride annulaire (180).

Abstract: Application de nanoparticules à base de polymères hydrophiles en tant que formes pharmaceutiques pour l'administration de macromolécules actives. Les nanoparticules (de taille nanométrique et de caractères hydrophile), également appelées nanosphères ou latex, sont des systèmes colloïdaux formés par la combinaison de polymères hydrophiles et d'un ingrédient actif de poids moléculaire élevé (macromolécule active, poids moléculaire supérieur à 1000 daltons). Les polymères hydrophiles sont le chitosane (un aminopolysaccharide) ou ses dérivés et le polyoxyéthylène ou ses dérivés. L'association de la macromolécule active avec lesdites nanoparticules se fait en phase aqueuse sans avoir besoin d'utiliser des solvants organiques ou des substances auxiliaires de nature toxique. La capacité de charge d'ingrédients actifs des nanoparticules est extrêmement élevée et de plus cette charge est libérée de façon contrôlée et prolongée dans le temps. En outre, lesdites nanoparticules ont une charge électrique superficielle positive dont l'intensité peut varier en fonction de leur composition.

Abstract: The process comprises determining from signals received on the two polarisation channels H and V of the radar, first on a single polarisation, an estimation of the precipitation ratios <o>R</o>a (19, 30-32) along the radar beam, in each door by distance i, then a first estimated value (<o>I</o>1) of the integral of precipitation ratios, and finally from the attenuated reflectivity coefficient (ZHa(r)) an estimation (35-38, 47, 48) of the non attenuated differential reflectivity coefficient (ZDRs(r)). Additionally, the measured value of the attenuated differential reflectivity coefficient (ZDRs(r)) is determined (30, 40-42) and the integral (<o>I</o>2) is deduced (43, 44) from the precipitation ratios and compared (45, 46) to the first estimated value (<o>I</o>1) so as to iteratively adjust a parameter ( alpha ) of the process applied to the polarisation H alone. When  alpha  is adjusted, the corrected values of the non attenuated reflectivity coefficient and of the precipitation ratio are obtained (38, 47). The invention applies to meteorological radars.

Title: Ultralow-loss silica glass and optical fibers using the same
Inventor: SAITOH KAZUYA
IPC: C03C13/04
Filed: 1997-07-14
Granted: 2002-10-29
Abstract: This ultralow-loss glass is characterized in that high purity silica glass contains 1 to 500 wt.ppm of at least one network modifying oxide. It is assumed that the network modifying oxide appropriately loosens the tetrahedral network structure of silica and hence Rayleigh scattering is decreased. Examples of the network modifying oxide include Na 2 O, K 2 O, Li 2 O, MgO, CaO, and PbO. Since  Rayleigh scattering losses are minimal in comparison with these of high purity silica glass, this impurity-added silica glass is excellent as a base material of a glass fiber for a long-distance transmission.
