Abstract: Methods and systems are disclosed for the production of hydrogen and the use of high-temperature heat sources in energy conversion. In one embodiment, a primary loop may include a nuclear reactor utilizing a molten salt or helium as a coolant. The nuclear reactor may provide heat energy to a power generation loop for production of electrical energy. For example, a supercritical carbon dioxide fluid may be heated by the nuclear reactor via the molten salt and then expanded in a turbine to drive a generator. An intermediate heat exchange loop may also be thermally coupled with the primary loop and provide heat energy to one or more hydrogen production facilities. A portion of the hydrogen produced by the hydrogen production facility may be diverted to a combustor to elevate the temperature of water being split into hydrogen and oxygen by the hydrogen production facility.

Abstract: The present invention relates to new 1-.beta.-methyl-2-thiolic carbapenem derivatives represented by the following general formula (I) and producing method thereof. ##STR1## The above-mentioned compound is very stable against DHP-1 enzyme due to effective shielding of carbapenem ring structually and is highly effective in both gram-positive and gram-negative microorganism, especially has a remarkable effect on the Pseudomonas aeruginosa known as a disease germ having strong resistance.

Abstract: Novel 1,2,4-trioxanes which possess anti-malarial activity.

Abstract: A high flux reactor is comprised of a core which is divided into two symetric segments housed in a pressure vessel. The core segments include at least one radial fuel plate. The spacing between the plates functions as a coolant flow channel. The core segments are spaced axially apart such that a coolant mixing plenum is formed between them. A channel is provided such that a portion of the coolant bypasses the first core section and goes directly into the mixing plenum. The outlet coolant from the first core segment is mixed with the bypass coolant resulting in a lower inlet temperature to the lower core segment.

Abstract: Improved cookware is disclosed having non-ferrous metal sidewalls and a natural stone bottom central portion. The non-ferrous metal sidewalls preferably are formed of an aluminum alloy having a coefficient of thermal expansion substantially equal to the coefficient of thermal expansion of the natural stone bottom. The natural stone bottom preferably comprises an iron-rich amphibole rock, and in the particularly preferred embodiment comprises hornblende.
