A 1.8-GHz CMOS VCO is presented, employing a monolithic transformer as an inductance with voltage-controlled value. The design was implemented in a standard digital 0.6 μm, 2-metal CMOS process and exhibits a 10% tuning range with a 2.7 V supply voltage and a 9 mA supply current. Phase noise measurements show a worst-case phase noise of about -112 dBc/Hz at 3 MHz offset from the carrier

The aim of this study was to analyze the added utility of contrast administration for spine MRI in children with scoliosis. A retrospective review of 663 consecutive contrast-enhanced spine MRI performed in 319 patients as part of the work up of scoliosis in children 2-18 years with clinically suspected or known scoliosis over a seven year period. Those patients with known tumors (13 patients) bei

Location management in cellular networks have been in focus for the research community for a number of years. The current static method of determining location or paging areas has been shown to be sub- optimal and costly for operators. Therefore, much research has been focussed on dynamic schemes, which show great promise in cost optimisation. However, the research has still been focussed on aggre

The cognitive- and neuro-sciences have supposed that the perceptual world of the individual is dominated by vision, followed closely by audition, but that olfaction is merely vestigial. Aslian-speaking communities (Austroasiatic, Malay Peninsula) challenge this view. For the Jahai — a small group of rainforest foragers — odor plays a central role in both culture and language. Jahai ideology revolv

Mobility, quality of service (QoS) support, and multicast routing capability are important requirements for today’s networks. This is a result of the changes in wireless users’ expectations, which favour group-oriented, high-quality, multimedia communication. Ad hoc networks enhanced with QoS multicasting strategies can provide users with these features. This paper defines the building blocks of a

Despite the perceived role of retailers to realize corporate supply chain responsibility, retailers face a number of structural and managerial challenges to effectively influence the sustainability parameters in upstream supply chain. At the same time, research that touches upon implementation of sustainable sourcing by food retailers is limited leaving aside the inter-organisational managerial im

Human x mouse hybridoma cells were grown in dialysis tubing (DT) to obtain large quantities of human monoclonal antibodies (MAb). Hybridoma cells were grown inside the DT, which was placed in a tissue culture flask containing medium. The medium inside the DT was supplemented with different additives which may be selected depending on the intended use of the MAb. About 10-50 times higher concentrat
