The dramatic increase of smart mobile devices and applications, the advent of Android OS, the increased number of wireless radios (incl. NFC) the support and the low awareness about security and privacy risks on the one hand, and the flatter, IP-based network architecture, the introduction of new radio technologies (femtocells, WiFi, LTE) and applications (M2M, NFC) on the other, have changed t...

In the classic RTK method using a single reference station the rover needs to work within a short range from the reference station due to the spatial decorrelation of distance-dependent errors induced by the ionosphere, troposphere and orbital errors. The operating range of RTK positioning is thus dependent on the existing atmospheric conditions and is usually limited to a distance of up to 10-...

Coordinates-based mechanisms have proven to be useful in a peer-to-peer architecture to predict Internet network distance, even more so than the already existing IDMaps scheme. One such mechanism has been analyzed known as Global Network Positioning (GNP) to provide insight on a current state of the art technology in network distance prediction. GNP instantiates a virtual geometric space by app...

PURPOSE Fracture of femur is a painful bone injury, worsened by any movement. This prospective study was performed to compare the analgesic effects of femoral nerve block (FNB) with intravenous (IV) fentanyl prior to positioning patients with fractured femur for spinal block. PATIENTS AND METHODS Sixty-four ASA I-III patients aged 18-80 years undergoing surgery for femur fracture were randomi...

introduction : the dynamic interaction between mother and infant is one of the indicative factors of infants’ social and emotional development especially in stressful situations as cognitive evaluating. methods: an experimental study was completed in 2010 in tehran on a total of 40 infants (18 boys and 22girls) forming two alternative groups and varying in age of infancy (4, 6, 8, 10 and 12 mon...

Commenting on a recent editorial in this journal which presented four challenges global health networks will have to tackle to be effective, this essay discusses why this type of analysis is important for global health scholars and practitioners, and why it is worth understanding and critically engaging with the complexities behind these challenges. Focusing on the topics of problem definition ...

Successful prevention and control of the epidemic of noncommunicable diseases (NCDs) cannot be achieved by the health sector alone: a wide range of organisations from multiple sectors and across government must also be involved. This requires a new, inclusive approach to advocacy and to coordinating, convening and catalysing action across civil society, best achieved by a broad-based network. T...

Mobile device positioning in ad hoc networks is a crucial issue due to the network properties and hardware limitations of particular devices (nodes). In this paper, a new conception of mobile device based on software defined radio architecture for mobile positioning in ad hoc networks is proposed. Sixport technology is implemented into our software defined radio receiver. Angle of arrival local...

Various treatment regimens for the relief of pain during endodontic therapy, including relief of occlusion, pre-medication, establishment of drainage, and intracanal and systemic medications are presented. In addition, the rationale for the use of placebos is discussed. Se presentan varios regimenes de tratamiento para el alivio del dolor durante la terapia endodóntica, inclu-yendo el alivio de...
