Abstract: The present invention provides a method for treating a used particulate filter, comprising: removing particulates from the particulate filter; and introducing simulated ash into inlet channels of the particulate filter after removing the particulates.

Abstract: A system that transdermally delivers a drug to a patient can be used to reduce suffering from acute/chronical musculoskeletal pain. The system includes a backing layer, an adhesive layer, a topical applicator, a suitable quantity of drug, and a quantity of topical carrier. The topical applicator is connected across and against the backing layer by the adhesive layer. The suitable quantity of drug and the quantity of topical carrier are homogenously mixed together as a topical medication, which is retained and dispensed from the topical applicator. The topical applicator includes a flat applicator body, a plurality of blunted spikes, and a containment rim. The flat applicator body is the structural base of the topical applicator. The containment rim is used to perimetrically confine the topical medication. The blunted spikes are used to increase the surface area of the topical applicator in order to improve its retention of the topical medication.

Abstract: An applicator-based transdermal drug delivery system (ABTDS) for administration of drugs to a patient to treat ailments in combination with a wide range of topical formulation classes including but not limited to creams, foams, gels, lotions, and ointments is described herein. The transdermal drug delivery system utilizes an applicator that can be in various disk-like shapes and sizes, and that contain the topical formulation in a fixed area, and is applied over the skin of the patient to ensure accurate drug delivery and protect the drug from being rubbed away. Additional features of the applicator include numerous blunt spikes present on its surface that are designed to enhance rate of drug delivery.

Abstract: The invention provides a multivariate modeling method for quantitative analysis by supervised principal component analysis (SPCA). The method comprises: (a) designing a plurality of calibration samples wherein the desired variances are dominant or greatly enhanced; (b) producing a calibration data matrix using suitable mathematical pretreatment and truncation of the acquired NIR/Raman spectra of the calibration samples; (c) decomposing the matrix using PCA; (d) evaluating the score and loading matrices to ensure a genuine orthogonal relationship between scores of the desired latent variables in a two-dimensional principal component space 7; (e) generating a prediction matrix for quantitative prediction of unknown samples. This method does not require testing of calibration samples using a reference method. In addition, this method has high tolerance to variations in sample composition and manufacturing conditions.
