Abstract: Embodiments of the present invention provide a cooling module for cooling heat-generating electronic devices in an immersion cooling system. The cooling module includes an integrated pump, which draws immersion fluid from the surrounding dielectric bath and drives it into a pressurized plenum to pressurize the coolant fluid and drive the pressurized coolant fluid through a nozzle plate containing a microconvective nozzle array. The array accelerates the fluid to produce a multiplicity of microjets that impinge on a surface of the heat-generating electronic device to be cooled. The effluent from the cooling module may be directed to flow into and wash over nearby heat-generating devices to help cool the nearby heat-generating devices. The effluent may also be directed to the inlets of daughter cooling modules attached to other heat-generating electronic devices.

Abstract: Compounds of formulae (3) and (I) for use as fluorescent markers for labelling an amine containing target drug, an amino acid or a protein are disclosed. Exemplary compounds are e.g. (II) (III) (IV).

Abstract: A plug (1) for use in occluding a fallopian tube hysterescopically, said plug comprising: an elongate body (2) having an external thread (3), characterized in that: said body is fenestrated (6,17; 7,18; 8,19).

Abstract: A plug (1) for use in occluding a fallopian tube hysteroscopically comprising an elongate body (2) having an external thread (3) characterised in that the body and/or external thread has/have a roughened and/or pitted external surface (4), or in that the thread is fenestrated (5), or in that the leading end (6) of the elongate body (2) is provided with an extension nose (7) having a smooth external surface (8) and a rounded terminal end (9), or in that the leading end (6) of the elongate body (2) is provided with a conic helix (11) of the same hand as the external thread (3), generally forming a continuation of the external thread (3). The invention also includes a drive tool, for inserting a plug (1) incorporating an integral flexible hysteroscope, and comprising an outer sleeve housing a flexible drive rod adapted, at one end to engage, and apply torque to, the trailing end (12,13) of the elongate body (2) of the plug (1), with the other end of the drive rod being manually rotatable by the surgeon.
