Abstract: A composition and method for the treatment of chronic sinusitis in which a composition containing desirable colonial bacteria is applied externally in the form of either a spray or a flush. The bacteria are selected from the genus Lactobacillus and the genus Bifidobacterium. The selected bacteria are provided in a therapeutically effective amount in a water solution.

Abstract: The trench-isolation structures for fabricating semiconductor devices using two different multilayer masking structures are disclosed by the present invention, in which the extended buffer spacers located in the isolation regions are formed on the sidewalls of two different multilayer masking structures having a masking dielectric layer on a pad-oxide layer and a masking dielectric layer on a conductive layer over a gate-oxide layer. The extended buffer spacers not only act as the etching mask for forming the trenches in the semiconductor substrate but also play significant roles for obtaining high-reliability and high-efficiency trench isolation of the present invention. The first role of the extended buffer spacers of the present invention is to offer the buffer regions for preventing the bird's beak formation around the edge of the active region during the thermal oxidation of the trench surface, so that the active area used to fabricate the active device is not sacrificed.

Abstract: The focus controlling system of the present invention can include a calibration paper, an image capturing device, an input interface, and a processing and controlling device. The image capturing device is employed for scanning the calibration paper. The image capturing device has a focus point adjusting mechanism. The input interface is utilized for receiving a location data of a scanning point. The processing and controlling device is responsive to the input interface and the image capturing device to control the focus point adjusting mechanism. The focus controlling method of the present invention includes the following steps. First, a scanning point is set or detected and a compensated magnification ratio for the scanning point is then calculated. A focus point of a image capturing device is adjusted and a calibration paper is scanned. The adjusting step and the scanning step are then repeated until a magnification ratio of the calibration paper is about the value of the compensated magnification ratio.
