BACKGROUND:Chlamydia causes infertility and increases risk of HIV infection, and population-based studies provide essential information for effective infection control and prevention.This study examined Chlamydia trachomatis prevalence and risk factors among a representative sample of 18-49-year-old residents in Hong Kong.METHODS:Census boundary ma
Abstract Objective A quantitative PCR (qPCR) assay for the detection of redside shiner (Richardsonius balteatus) environmental DNA (eDNA) was designed as a side product of a larger project aimed at using eDNA to determine the presence and geographic extent of native and non-native fishes in the reservoirs and associated tributaries above the three
We describe the iterative algorithm for television image superposition.The superposition is defined by offsets, scale, and rotates.Also additive and multiplicative noise influences the image.The main aim of developing this algorithm is to reduce the time of processing images for estimation superposition parameters.Reducing processing time is provid
Under the repeated action of traffic and thermal loads, a cement concrete pavement slab may partially lose contact with its base course, and voids may develop underneath maglione loro piana the slab.Such distress will greatly impact the pavement performance.To fill the voids and restore the base support to the slab, the technology of polymer grouti
On the base of a rigorous mathematical accles and shelvoke model, the problem of the contact interaction of a heated flat punch of an elliptical section with a transversely isotropic elastic half-space is investigated.It is assumed that the half-space surface is the isotropy plane of a transversely isotropic material, and also that there is a smoot
