Review of novel energetic polymers and binders - high energy propellant ingredients for the new space race.

Current solid rocket propellant formulations still employ traditional ingredients utilized since the 1960s, such as hydroxyl terminated polybutadiene (HTPB). Recent advances in energetic polymer see many binders capable of providing higher specific impulse and burn rates over HTPB. As shown by calculations, even slight increases in specific impulse can drastically increase the maximum payload of a launch system.

Valium without dependence? Individual GABA receptor subtype contribution toward benzodiazepine addiction, tolerance, and therapeutic effects.

Benzodiazepines are one of the most prescribed medications as first-line treatment of anxiety, insomnia, and epilepsy around the world. Over the past two decades, advances in the neuropharmacological understanding of gamma aminobutyric acid (GABA) receptors revealed distinct contributions from each subtype and produced effects. Recent findings have highlighted the importance of α containing GABA receptors in the mechanisms of addiction and tolerance in benzodiazepine treatments.
