Abstract: Positive air pressure is applied on a ventral side of a plant canopy and negative air pressure is applied on a dorsal side of the plant canopy. By this arrangement, the negative air pressure draws air supplied by the positive air pressure on the ventral side of the plant canopy across the plant canopy past the dorsal side of the plant canopy to withdraw heat from the plant canopy, for example, from an agricultural lighting system and/or humidity from plant respiration in a controlled indoor environment.

Abstract: The present invention provides a reduced fat chocolate composition comprising erythritol. In one embodiment the chocolate composition is characterized in that it has a total fat content of from 15 wt % to 24.9 wt %. In another embodiment the chocolate composition comprising erythritol is characterized in that it has a total fat content of from 15 wt % to 26 wt % and does not comprise inulin or fructo oligosaccharide (FOS). A process for the preparation of the chocolate composition is provided, said process having processing parameters similar to those for high fat chocolate.

Abstract: A stylet for an image guided system, which includes a locating device and which is operable for emitting an electromagnetic field for locating the stylet. The stylet includes a flexible elongate member, an electrically conductive member, and a reinforcement member. The reinforcement member is disposed inside the electrically conductive member and is made out of a magnetic material. The reinforcement member reinforces the stylet and provides electrical communication between the conductive member and the locating device such that current induced in the conductive member is transmitted to the locating device via the reinforcement member.

Abstract: The present invention provides a chocolate composition comprising erthyritol and one or more ingredients selected from maltodextrin, a high protein ingredient, maltitol and polydextrose. Erythritol may be used in place of some or all of the sucrose normally employed in a chocolate composition and thereby provide a chocolate composition having a reduced sugar and/or calorie content chocolate. A process for the preparation of the chocolate composition is also provided.

Abstract: A bifurcate stent delivery catheter is disclosed that includes a proximal shaft and two distal shaft branches having a bifurcated stent mounted thereon, wherein one or more conventional balloon catheters may be advanced within lumens of the bifurcate catheter to deploy the bifurcated stent. Since no balloons are mounted on the bifurcate catheter, the clinician may use any combination of balloon sizes for deploying various portions of the bifurcated stent and thus custom-select appropriate balloon sizes to best treat the bifurcation. Once a conventional balloon catheter is positioned within a distal shaft branch of the bifurcate stent delivery catheter, each of the distal shaft branches of the bifurcate catheter are constructed to split or otherwise expand in a controlled manner upon expansion of the balloon catheter in order to allow the bifurcated stent to be expanded or deployed.

Abstract: A supported Ziegler catalyst prepared by a process comprising treating a magnesium containing support material with a titanium compound in the presence of a tin compound having the formula Sn(OR').sub.m X.sub.4-m wherein R' is a hydrocarbyl radical, m is 0-4 and X is halogen. The catalyst is used with a conventional co-catalyst e.g. a trialkyl aluminium compound.
