Cryptococcus neoformans usually causes disease in patients with human immunodeficiency virus (HIV) infection. This descriptive study was based on a retrospective review of 33 HIV-uninfected patients with disseminated cryptococcosis from 1998 to 2005. An underlying condition associated with immunocompromise was documented in 30 patients (90.9%), including(More)
We have examined the self-assembly process of octadecyltrichlorosilane on silicon using x-ray reflectivity. By comparing the commonly used ‘‘interrupted-growth’’ characterization technique with results obtained in situ, we have determined that quenching the growth and then rinsing and drying the sample introduces free area into the film, presumably by(More)
A two-step interface capturing scheme, implemented within the framework of conservative level set method, is developed in this study to simulate the gas/water two-phase fluid flow. In addition to solving the pure advection equation, which is used to advect the level set function for tracking interface, both nonlinear and stabilized features are taken into(More)
This study was to determine the diagnostic value of procalcitonin (PCT) in the differentiation of infectious and non-infectious causes of pleural effusion. From January 2005 to April 2005, we measured the PCT levels of pleural effusion from 76 patients using an immunoluminometric assay. The types of pleural infusions studied were para-pneumonic effusion (n(More)
This paper presents the evaluation results of whiskers on two kinds of lead-free finish materials at the plating temperature and under the reliability test. The rising plating temperature caused increasing the size of plating grain and shorting the growth of whisker. The whisker was grown under the temperature cycling the bent shaped in matte pure Sn finish(More)
The microstructures and shear strength of the interface between Sn–Zn lead-free solders and Au/Ni/Cu interface under thermal aging conditions was investigated. The intermetallic compounds (IMCs) at the interface between Sn– Zn solders and Au/Ni/Cu interface were analyzed by field emission scanning electron microscopy and transmission electron microscopy.(More)
Water-cast films of two ethers of cellulose, hydroxypropylcellulose (HPC) and hydroxyethylcellulose (HEC), with dispersed silica particles, were deposited on flat substrates. X-ray specular reflectivity was used to characterize the structure of these solid ca. 1000 Å thick films as a function of the added colloidal fraction. It was shown that the structural(More)
