When reprocessing surgical instruments, process design is significant, in particular the choice of relevant process parameters for the effective removal of blood, the most common soil present. Cleaning performance is highly dependent, among other factors, on the alkalinity of the cleaning solution at appropriate temperatures to ensure that relevant specifications are fully complied with on site...

Inhibition is a cognitive ability that allows humans to respond flexibly rather than reflexively to events. The purpose of this investigation is to elucidate the neural basis of inhibition in healthy humans. Combining magnetoencephalography and functional MRI, two unqiue brain imaging instruments, allows both key brain regions and the timing of neuronal processes involved with inhibition to be ...

John Maxwell Fairley was a prolific collector and amassed quite a collection of old dental instruments, obtained mainly from the North East of Scotland. John qualified LDS in 1941 and a year later graduated BDS from St Andrews University. He was a member of the Lindsay Society in 1985 and on the committee from 1988 until 1990. One of his contributions to dental history was a comprehensive accou...

A tool was developed that assists surgeons in manipulating surgical instruments more precisely than is possible manually. The tool is a telemanipulator that scales down the surgeon's hand motion and filters tremor in the motion. The signals measured from the surgeon's hand are transformed and used to drive a six-degrees-of-freedom robot to position the surgical instrument mounted on its tip. A ...

We present the timing and spectral properties of the transient Be/X-ray binary pulsar 3A 0535+262 during quiescence using three observations with the narrow field imaging instruments (NFI) of BeppoSAX. Assuming a distance of 2 kpc for this system, the 2–10 keV X-ray luminosities measured from the three observations are in the range of 1.5–4.0 × 10 33 erg s −1 , indicating a very low rate of acc...

The need for properly trained sterile processing staff members has grown with the increased sophistication of surgical procedures. In 1998, I conducted a survey of hospitals about various aspects of training sterile processing personnel, including the length of time for training employees to process general surgical and specialty surgical instruments. To evaluate trends, I conducted a second su...

Background Haemorrhoidectomy is frequently associated with significant postoperative pain and prolonged hospital stay; different techniques and devices have been developed to overcome these problems, including modifications of the technique (excision without legation) and introduction of new surgical instruments (LigasureTM, Harmonic ScalpelTM). We evaluated the surgical outcomes of Milligan Mo...

BACKGROUND Guidance on the cleaning of dental instruments in primary care has recently been published. The aims of this study are to determine if the publication of the guidance document was enough to influence decontamination best practice and to design an implementation intervention strategy, should it be required. METHODS A postal questionnaire assessing current decontamination practice an...

This research studied the authentication of hazelnut oil by portable FT-NIR, FT-MIR, and Raman spectrometers. Hazelnut oils were adulterated with vegetable at various concentrations (0-25%) (w/w). Collected spectra analyzed using Principal Component Analysis (PCA) Soft Independent Modelling Class Analogy (SIMCA) to generate classification models authenticate pure Partial Least Squares Regressio...

We report performance verification observations of the giant elliptical galaxy M87 in the Virgo Cluster with the MOS, pn, and optical monitor instruments on board of XMM-Newton. With the energy sensitive imaging instruments MOS and pn we obtain the first spatially constrained X-ray spectra of the nucleus and the jet of the galaxy. The good photon statistics of the pn and MOS allow a detailed an...
