OBJECTIVES To assess the impact of the menstrual cycle on the diagnostic performance of various assays for detection of Chlamydia trachomatis in home obtained and mailed vaginal flush and urine specimens. METHODS A ligase chain reaction assay (LCR; Abbott Laboratories), a transcription mediated amplification assay (TMA; Gen-Probe), and an enzyme amplified immunoassay (PCE; Dako Diagnostics) w...
We introduce pretty clean modules, extending the notion of clean modules by Dress, and show that pretty clean modules are sequentially CohenMacaulay. We also extend a theorem of Dress on shellable simplicial complexes to multicomplexes.
The EZ Streak urine culture device (Difco Laboratories, Detroit, Mich.) combines the advantages of both the dip-slide and the classic urine culture technique, enabling bacterial enumeration and isolation following a simple inoculation step. Five hundred clean-catch urine specimens submitted by outpatients attending a health maintenance organization were used to compare the EZ Streak with cultur...
The aim of the present study was to evaluate the illegal Silver pomfret catch by fixed gill-nets in Hormozgan inshore waters (Qeshm Island). Sampling was performed in Bandar Laft estuaries through three fishing boats between April to July 2015. The fishing gears were the nylon mono-filament fixed gill-net with 6.5 cm mesh size (bar), 200 m length and 8-10 m height. The non-parametric bootstrap ...
The Precautionary Principle provides a framework for action to protect human health and the environment in the face of uncertainty. The central premise of the precautionary principle is that when an activity poses threats of serious, irreversible harm to human health or the environment, we should act to prevent that damage – even if science has not fully worked out the details of the relevant c...
BACKGROUND Alongside the major health risks posed by environmental pollution in China are recent achievements on several environmental issues that have affluent Western nations racing to catch up. The country has propelled itself to a position of leadership in clean energy and efficiency, for instance, with important consequences for public health. OBJECTIVES We comment on China's challenges ...
We present a study of weak lensing shear measurements for simulated galaxy images at radio wavelengths. We construct a simulation pipeline into which we can input galaxy images of known shapelet ellipticity, and with which we then simulate observations with eMERLIN and the international LOFAR array. The simulations include the effects of the CLEAN algorithm, uv sampling, observing angle, and vi...
background and objectives: urinary tract infection is one of the most common bacterial infections in the human population, and more frequent infection during pregnancy. with notice to this point that most of urinary tract infections during pregnancy are asymptomatic, they could lead to serious complications such as prematurity, low-birth weight, hypertension, and higher fetal mortality rates if...
In this paper an experimental characterization of a typical indoor wireless propagation channel is performed. This channel characterization is needed for short range applications (<10m), utilizing Ultra-Wideband Impulse Radio (UWB-IR) techniques. Both the line of sight (LOS) and the non line of sight (NLOS) scenarios are taken into account. The characterization is done using time domain measure...
This paper analysis the characteristics and ambiguity function of the single-channel and multichannel DVB-T signals, and choose the multi-channel DVB-T signal as opportunity illuminators to do the research of ISAR imaging. Firstly, the target’s echo using single-in-multi-out mode for passive ISAR image is derived, together with the analysis of the composition of the echo’s spatial spectrum. Con...
