摘要:
A device for generating bubbles or droplets may include a cavity comprising a first pressurized phase, at least one input capillary of a second phase, and an output capillary coaxially aligned with the at least one input capillary. The opening of the tip of the at least one input capillary has an internal diameter of less than half the internal diameter of the output capillary. The cross section of the cavity may be selected so that, in use, the average speed field in the cavity is quasi-static.

An example medical device is disclosed as an expandable stent. The stent includes a tubular scaffold having an inner surface, an outer surface, and a lumen extending therein. The expandable stent also includes a liner disposed within the lumen of the tubular scaffold. Further, the liner is radially spaced from a medial region of the tubular scaffold to define a tissue ingrowth region along an uncovered portion of the medial region. Additionally, the liner extending along the tissue ingrowth region is configured to limit the amount of tissue ingrowth along the medial region of the scaffold.

A method of selective catheterism of in a network of conduits of an anatomical structure including inserting a flexible distal end of a guide for catheterism through the network of conduits. An appendage is attached on the distal end of the guide, the appendage includes a channel extending along a longitudinal axis of the guide. A catheter is slid along the catheter until a distal face of the catheter surrounding the guide engages a proximal surface of the appendage. A force oriented in a distal direction is exerted with the catheter on the appendage, which disengages the appendage from the distal end of the guide within the network of conduits. Navigation through the network of conduits is continued with the flexible distal end of the guide once the appendage is removed.

Force transducer (10) include two structural members (11, 12) spaced apart to define a gap (101) and being linked to each other. Optical fibres (13) are to the members and are freely suspended in the gap. The optical fibres are configured to provide a change in a detectable optical property responsive to a change in relative position between the two members in one or more predetermined degrees of freedom. Each of the optical fibres (13) is fixed to both structural members and continuous between the members to link the two structural members to each other. The optical fibres are substantially the only structure forming a link between the two structural members (11, 12), such that the arrangement of the optical fibres defines substantially the stiffness of the link between the two structural members in the one or more predetermined degrees of freedom, which stiffness is mainly, such as for at least 95%, determined by the optical fibres.
摘要:
The present invention is related to a method for protecting a metal substrate against corrosion comprising the step of: —generating a plasma in a gaseous medium by means of a plasma device; —placing the substrate in contact with the plasma, or in a post-plasma area of said plasma; —introducing in said plasma or in said post-plasma area a corrosion inhibitor along with an organic precursor, thereby depositing a barrier layer comprising the corrosion inhibitor, the deposited layer protecting the metal substrate against corrosion.
摘要:
A computer device includes means for receiving a request for at least one random number; means for generating a message authentication code from the identifier and at least one random number to be transmitted; and means for creating a message for transmission, including the random number in plain text and the message authentication code. A random number distribution system includes the computer device; a communication network; and a receiver device connectable to the computer device via the network to transmit requests for random numbers to the computer device and to receive messages from the computer device.
摘要:
The invention relates to in vitro methods for differentiating mammalian pluripotent stem cells into cells displaying a neuronal phenotype, more particularly into cortical-type neurons including inter alia pyramidal neurons and cortical inhibitory interneurons. The invention further encompasses so-obtained neuronal cells and cell population, compositions comprising such, and further uses of said neuronal cells and cell population.
摘要:
A method to determine the clinical outcome of breast tumour affecting a patient if treated with an antitumoural agent against breast tumour, the said method comprising the step of assaying a sample of a breast tumour from said patient for an expression level of selected genes, by contacting mRNA sequences from the cells of this breast tumour with a set of more than 3 nucleotide sequences related to human mutated PIK3CA.
