BACKGROUND When shared by people who inject drugs, needles and syringes with different dead space may affect the probability of HIV and hepatitis C virus (HCV) transmission differently. METHODS We measured dead space in 56 needle and syringe combinations obtained from needle and syringe programs across 17 countries in Europe and Asia. We also calculated the amounts of blood and HIV that would...

Using the threshold equalizing noise (TEN) test, 49 subjects with at least two pure-tone thresholds per ear greater than 50 dB HL and none greater than 80 dB HL were evaluated for the presence or absence of dead regions. The purpose of this study was to (1) assess the prevalence of cochlear dead regions in this clinical population, (2) measure whether listeners with dead regions performed diffe...

In this paper, an automatic method of counting the passing people through the gate by using two space-time images is proposed. In the proposed method, the images are obtained in series by using a camera which is hung straight from the ceiling of the gate, so that the data of the passing people are not overlapped each other in the images. First, a spacetime image which includes the data of the p...

Ancient Greek literature gives us many relevant traces of the way people represented maritime spaces. Greek narratives endow these spaces with meaning and make them legible. Indeed, these testimonies are a significant contribution to our knowledge of the “odological” space at sea, a space of description including numerous cultural features rather than a space described. This space is based on e...

During experimental evaluations of RPL on a network with some 20 Zolertia Z1 motes running Contiki version 2.6, inconsistent Packet Delivery Ratios (PDR) and message latencies were frequently observed. Replacing ContikiMAC by NullRDC brought consistency, proving that the problem had to be found in the Radio Duty Cyling (RDC) protocol. Two implementation issues of ContikiMAC were found guilty. T...

In this paper, we consider the use of history of mathematics as a methodology in the teaching and learning of mathematics in Singapore, in particular at the polytechnic and junior college level. More specifically, we investigate how the history of mathematics can be integrated into the Singapore classroom via a spectrum of well-studied and time-tested lesson designs. In the ensuing discourse, w...

OBJECTIVES The Dead Sea, the deepest and most saline lake on earth, has been known from biblical times for its healing properties. The aim of this systematic review was to present critically the level of evidence for the claims of therapeutic effects of Dead Sea treatments in several rheumatologic diseases and psoriasis as well as to review these treatments' safety. METHODS All articles cited...
