BACKGROUND Adrenal ganglioneuroma (GN) is extremely rare. The present study is to describe the largest series of this adrenal tumor treated in a single medical center to our knowledge. METHODS Clinical details, radiologic, laboratory, and pathologic findings as well as follow-up data were analyzed retrospectively in 17 patients with incidentally(More)
An acclimated activated sludge was examined for its ability to degrade meta-fluorophenol as sole carbon source in aerobic batch cultures. The mechanism study revealed that the initial step in the aerobic biodegradation of meta-fluorophenol was their transformation to fluorocatechol. Following transformation of the fluorophenol to fluorocatechol, ring(More)
Reliable communication is essential for the success of global collaborative software development efforts. Software development organizations and methodologies must be tailored to avoid communications issues which may result in misunderstood requirements or missed project milestones. Extreme Programming (XP) was adopted for the Lattice/sup /spl reg// Trading(More)
BACKGROUND With no generally accepted criteria for preoperative differential diagnosis between benign and malignant adrenal lesions, management of adrenal incidentalomas, especially those between 4 and 6 cm, remains controversial. PATIENTS AND METHODS Clinical details, radiological diagnosis, laboratory examination, intervention measures, and follow-up(More)
Requirement changes and the involved rework are inevitable if the requirement changes could not be foreseen. Extreme programming (XP) suggests the customer be on site with the developers. The requirement changes may be forecast by the on site customer from the business perspective and by the developers from the technology perspective. Extreme programming(More)
Let χ λ (cf (1.1)) be the unit spectral projection operator with respect to the Laplace-Beltrami operator ∆ on a closed Riemannian manifold M. We generalize the (L 2 , L ∞) estimate of χ λ by Hörmander [3] to those of covariant derivatives of χ λ Moreover we extend the (L 2 , L p) estimates of χ λ by Sogge [7] [8] to (L 2 , Sobolev L p) estimates of χ λ .
Since there are mass of images in the outward-appearance patent-image database, a retrieval approach developed for this database is greatly demanded. The shape information of the patent image is the key feature for a patent image. Therefore, we present an outward-appearance patent images retrieval approach based on contour-description matrix. This matrix(More)
Let G be a homotopically trivial and effective compact Lie group action on a compact manifold N of nonpositive curvature. Under certain assumptions on N we prove that if G has dimension equal to rank of Center π 1 (N), then G must be connected. Furthermore, if on N there exists a point having negative definite Ricci tensor, then we show that G is the(More)
OBJECTIVE It was the aim of this study to observe the effects of sequential hemoperfusion (HP) and continuous venovenous hemofiltration (CVVH) on patients with severe tetramine poisoning and to evaluate the ability of these modalities to remove tetramine. METHODS Eighteen patients diagnosed as having severe tetramine poisoning were treated by blood(More)
