The invention provides a process for the production of hydrogen, comprising catalytically decomposing a concentrated aqueous solution of potassium formate in a reaction vessel to form bicarbonate slurry and hydrogen, discharging the hydrogen from said reaction vessel, and treating a mixture comprising the bicarbonate slurry and the catalyst with an oxidizer, thereby regenerating the catalyst. Pd/C catalysts useful in the process are also described.

Method for storage and release of hydrogen

A hybrid heating system and method including: (a) a heat pump water heating system; (b) a conventional heating system including a conventional heater having a surface heat exchanger, and a primary circulation arrangement fluidly communicating with the surface exchanger, the primary circulation arrangement adapted to effect an exchange of heat between the surface heat exchanger and a flow of liquid to produce a heated flow of liquid; (c) a plurality of sensors associated with the heat exchange system; (d) an input arrangement adapted to provide cost data pertaining to a first power cost for supplying power to the heat pump system, and to cost information pertaining to a second power cost for operating the conventional system, and (e) a processor including a memory storing criteria specifying when to operate the heat pump water heating system, and when to operate the conventional heating system.

Hybrid heating system

The present invention discloses therapeutic natural products, in particular plant extracts effective in treating and preventing urinary tract disorders, and method for obtaining said extracts. In particular, the present invention discloses a water-soluble alcoholic extract of-flower (NABIA extract), a component thereof (NABIA fraction) or any mixture of components thereof, which is substantially free of non water-soluble residues, and exhibits an effective alpha-1-adrenergic receptor blocking activity. Further are disclosed methods of preparing this extract and methods of inhibiting alpha-1-adrenergic receptors and/or 5-alpha-reductase, as well as of treating medical conditions associated therewith, such as urinary tract disorders.

Natural water soluble extracts for the inhibition of alpha-1-adrenergic receptors

The invention provides a process for reducing substantially water insoluble organic compounds containing reducible groups comprising contacting these compounds with an aqueous solution of a formic acid salt in the presence of a hydrogenation catalyst and in the substantial absence of a phase transfer catalyst.
