Finding out the optimal sampling positions for measurement of ventilation rates in a naturally ventilated building using tracer gas is a challenge. Affected by the wind and the opening status, the representative positions inside the building may change dynamically at any time. An optimization procedure using the Response Surface Methodology (RSM) was(More)
BACKGROUND Rectal cancer is a common malignancy with considerable mortality. This review outlines the current status of laparoscopic total mesorectal excision as a treatment option for rectal cancer and emphasizes the need for standardized approaches. METHODS We searched PubMed for the terms "total mesorectal excision," "rectal cancer," and "laparoscopic(More)

This paper describes an underwater 300m micro underwater work tool –MUWT(named huwt-3E, stands for three functions micro electric manipulator in China).The working principle and components of multi-sensors are introduced in detail. The pressure-compensated joint is compact designed and integrated of a micro permanent magnet (PM) brushless motor, a drive(More)
OBJECTIVE To investigate the feasibility and clinical characteristics of small partial laryngectomy without tracheotomy for T1-2 stage glottic carcinoma. METHOD Forty-five patients with laryngeal squamaous cell carcinoma in T1-2 stage received small partial laryngectomy without tracheotomy. RESULT All patients were primarily healed and were hospitalized(More)
A robust high performance liquid chromatography with fluorescence detection method (HPLC-FLD) was developed for the determination of five rhubarb anthraquinones in rat plasma using a quality by design approach. A Plackett-Burman design was utilized to screen the effects of methanol content, the pH value of mobile phase, the flow rate, column temperature,(More)
The qualitative model for rapidly discriminating the waste oil and four normal edible vegetable oils is developed using near infrared spectroscopy combined with support vector machine (SVM). Principal component analysis (PCA) has been carried out on the base of the combination of spectral pretreatment of vector normalization, first derivation and nine point(More)
The self-referenced spectral interferometry (SRSI) technique, which is usually used for microjoule-level femtosecond pulse characterization, is improved to characterize weak femtosecond pulses with nanojoule based on the transient-grating effect. Both femtosecond pulses from an amplifier with 3 nJ per pulse at 1 kHz repetition rates and femtosecond pulses(More)
