In order to assess the risk for mercury poisoning in dentists, urine specimens were collected and analysed from 250 dentists (190 male, 60 female). Subject data and pertinent health symptoms were asked via a questionnaire. The results indicate that the mean and standard deviation of mercury values were 51.3± 38.0 µg/L, while 27.2 percent of dentists had levels within normal limits (0-19 µg/...

The control limits of an exponentially weighted moving average (EWMA) control chart should vary with time, approaching asymptotic limits as time increases. However, previous analytic analyses of EWMA charts consider only asymptotic control limits. In this article, the run length properties of EWMAs with time-varying control limits are approximated using nonhomogeneous Markov chains. Comparing t...

we prove that the class of profinite groups $g$ that have a factorization $g=ab$ with $a$ and $b$ abelian closed subgroups, is closed under taking strict projective limits. this is a generalization of a recent result by k.h.~hofmann and f.g.~russo. as an application we reprove their generalization of iwasawa's structure theorem for quasihamiltonian pro-$p$ groups.

receptors and proteins are overexpressed in many human cancer cell membranes rather than normal tissues and are considered as the main molecular targets. specific tumor- targeting molecules which have high affinity for these receptors can be valuable tools as carrier molecules for targeted cancer therapy and imaging. pharmacokinetics and bioavailability of diagnostic and therapeutic agents are ...

A 43-year-old middle-eastern woman was visited with a 15-year history of multiple painful cutaneous nodules on her back. The first lesion appeared on her back when she was 28 years old. As she aged, the lesions became larger, more numerous, and more painful with cold or physical contact. Her medical history was not significant. The patient’s medications included naproxen, calcium-D, and vitamin...

The target costing technique, mathematically discussed by Sauers, only uses the p C index along with Taguchi loss function and X -R control charts to setup goal control limits. The new specification limits derived from Taguchi loss function is linked through the p C value to X -R control charts to obtain goal control limits. In this study, the target costing technique is exploited by further co...

In human several kinds of electrocardiographic findings have been reported in association with pneumothorax such as decreased and/or alternating QRS amplitude (electrical alternans). However, electrocardiographic changes concurrent with pneumothorax have rarely been discussed in veterinary literature. A 3-year-old male crossbreed dog was presented with a history of car accident. Thoracic au...

The activities of superoxide dismutase and glutathione peroxidase in the red cells of normal and acatalasemia bloods were compared. Superoxide dismutase activity in the red cells of Japanese acatalasemia blood was higher than in normal control, while glutathione peroxidase activity remained within normal limits. Cyanide sensitivity of superoxide dismutase in the red cells of acatalasemia blood ...
