An apparatus and method are disclosed for cooling one or more exercising or resting individuals by applying a water mist and dry air. The apparatus can be free standing, fixed to the walls or ceiling, or attached to an object on which an individual is resting or exercising. The mist and dry air can be applied together or separately, simultaneously or alternately, with varying timing and intensity. In some embodiments, the mist and dry air are manually controlled or operate according to the passage of time. In other embodiments the need for cooling is determined by one or more physiological parameters measured by sensors directed toward or attached to an individual, or embedded in an object on which an individual is resting or exercising. Still other embodiments estimate the heating of the individual by measuring the amount of work performed or the rate of energy expenditure.

Device for applying cooling mist and dry air to individuals

An apparatus and method of use are disclosed for cooling one or more exercising or resting individuals with a water mist while automatically preventing the undesirable accumulation of excess water. In some embodiments, a sensor detects accumulated water on or near an individual, while other embodiments use measured climate parameters to predict water accumulation. The apparatus can be free standing, fixed to the walls or ceiling, or attached to an object on which an individual is resting or exercising. In some preferred embodiments, the apparatus is controlled according to the passing of time and/or one or more measured physiological parameters measured by sensors directed toward or attached to an individual, or embedded in an object on which an individual is resting or exercising. In some embodiments dry air is also applied either simultaneously or alternately with the mist to enhance cooling and further discourage water accumulation.

Device for applying cooling mist to individuals without water accumulation

A normal CPMAS experiment is modified to provide for spectral editing. In one embodiment of the invention, the conventional CPMAS experiment is performed with the proton decoupling RF applying at a frequency slightly different than the proton resonance frequency in order to suppress methylene (CH.sub.2) resonances more severely than CH and CH.sub.3 resonances. In another embodiment of the invention the RF pulse sequence normally using during the cross-polarization period is replaced with a WIM RF pulse sequence which has the effect of suppressing the CH and CH.sub.3 resonances, thereby leaving the CH.sub.2 resonances.

Method for editing CPMAS solid-state NMR spectra

A new RF pulse sequence is applied to selected nuclei in the evolution period of a 2D NMR heteronuclear correlation experiment to more effectively suppress heteronuclear interactions. The new pulse sequence is designed to be effective with the existing BLEW-12 pulse sequence so that both homonuclear and heteronuclear interactions are suppressed. In addition, the new pulse sequence effectively suppresses homonuclear interactions so that it can be used with a variety of nuclear species.
