Abstract: Treatment technology directed to using mine waste as a raw material to manufacture a mine filling product for use as a suitable precursor product or mine filling product to be used as a backfill material to close a mine. The precursor product or mine filling product retains its metals and is not be able to generate acidity. According to the disclosure, the precursor product or mine filling product, when placed in a mine, may also remove metals from mine fluids in the mine it contacts, and still retain the metals it hosted when it was a mine waste prior to it being used as a raw material to manufacture the precursor stowing backfill product.

Abstract: Systems and methods for determining turbine engine system stability encompass measuring or otherwise determining values of performance parameters, storing a data set of such values in memory, generating a stability indicator, and displaying the stability indicator on an operator interface. The stability indicator is generated by a processor operating in data communication with the computer memory, utilizing customized software algorithms to remove high frequency components, apply an adaptive filter to adjust selected parameters according to a target value of a selected target parameter, and apply a stochastic filters to estimate true values of the selected parameters, based on the remaining variation.

Abstract: A method for training a gas turbine engine test cell operator during a simulated engine test is provided. The method includes transmitting, from a data acquisition and control system (DACS) to a software engine model, data indicative of at least one of an operator input and an instructor input. The method further includes receiving the data at the software engine model and transmitting response data from the software engine model to the DACS, the response data simulating to the DACS that an operational state of a live engine has changed in response to the at least one of an operator input and an instructor input. The method also includes receiving the response data at the DACS and outputting an indication of the changed operational state to the operator based on the response data.

Abstract: Methods for making a storage package having a breaching bubble(s) opening mechanism are described.

Abstract: It has been demonstrated that conjugated linoleic acid isomers with the first double bond in position 9 (cis) or 10 (trans), added exogenously, can be desaturated in position 6 by the cyanobacterium Spirulina platensis. The metabolites, 6-cis, 9-cis, 11-trans-octadecatrienoic and 6-cis,10-trans,12-cis-octadecatrienoic acids, which have not previously been characterized, were isolated by a combination of chromatographic techniques and the structures were confirmed by gas chromatography-mass spectrometry in the form of picolinyl ester and dimethyloxazoline derivatives.

Abstract: An aircraft includes a fuselage having a lower fuselage part and a fluid tank located adjacent the lower fuselage part, the fluid tank being at least partially filled with fluid and an open cell foam material so that in the event of impact on the lower fuselage part, fluid is constrained to flow through the foam material to provide controlled deformation of the lower fuselage part.

Abstract: An optical fibre amplifier, laser or superluminescent source, consisting of a chalcogenide glass matrix hosting trivalent rare earth ions and which is doped with oxide in the form of a metallic oxide. The device utilizes the properties of the added oxide to improve the fabrication and efficiency of optical waveguide sources, in particular for applications around 1.3 &mgr;m. Specifically, the oxide broadens the wavelength range for pump absorption, broadens the wavelength range for light emission, increases the device efficiency through a change in lifetime of certain laser levels and modifies properties of the glass to prevent crystallization during fiber fabrication. The device exploits the intentional addition of oxide to improve amplifier, laser, glass and fiber properties.

Abstract: An insulated garment which includes an outer fabric and an inner fabric and at least two layers of insulation between the inner and outer fabrics. A first layer of insulation contiguous to the outer fabric is a synthetic material and a second layer of insulation contiguous to the inner fabric is goose down. Stitching maintaining the inner and outer fabrics to the two layers of insulation is patterned so that the stitching of one of the layers of insulation is contiguous to mid-points between the stitching of the second layer of insulation.

Abstract: Breaching access structure 10S provides easy access to sealed interior 10I containing contents 10C. Access region 12A proximate edge 12E of package 10, provides entrance into the interior and access to the contents. Band seal 14 formed by the upper lamina 14U and lower lamina 14L extends along the access region, enclosing breaching bubble 16. The band seal has inner seal portion 14I between the bubble and the interior, and outer seal portion 14O between the bubble and edge 12E of the package. The bubble is expandable to open the package in response to bursting detonator 18. The detonator is burst by external pressure applied by a user. Opposed pair of peel flaps, upper flap 16U and lower flap 16L, are formed by the opposed laminae of the outer seal along the edge breach as the bubble breaches. These small initial flaps are grasped by the user and manually peeled apart to initiate opening the band seal.
