Abstract: A method and apparatus are provided to quantify psychological and physiological components to measure acute stress in humans, in which a stimulus can be applied to the test subject's environment during the test. The method involves multiple stress/relaxation intervals while physiological measurements are taken and “measured,” and involves questionnaires that are answered after each of the intervals to “measure” the test subject's psychological state. A computerized testing apparatus acquires the physiological measurements, and also is used by the test subject in answering the questionnaires. The “stimulus” can be a fragrance, flavor, product, or task, and a “blank stimulus” is normally used during one of the stress intervals.

Abstract: A nozzle spray head is provided for use in a dynamic electrostatic air filter, in which the nozzle spray head assembly exhibits multiple nozzle orifices as outlet ports, which extend from the bottom of the nozzle body such that the distances between the outlet ports and a target member are not constant. The charged multiple outlet ports exhibit a more uniform electric field at their tips, thereby enabling a better and more uniform spray pattern to be emitted by each of the individual outlet ports. In one embodiment, the outlet ports are grouped in concentric circles, in which the innermost circle comprises outlet ports of the greatest lengths, and the outermost circle comprises outlet ports of the smallest lengths.

Abstract: 2-Decarboxy-2-phosphinico prostaglandin derivatives are disclosed. These derivatives comprise a modified ?-chain and an ?-chain bonded to a ring structure. The modified ?-chain has a 2-decarboxy-2-phosphinico group. The derivatives can be used to treat a variety of pharmaceutical and cosmetic conditions.
