This paper present a single stage CMOS Voltage controlled oscillator with a high oscillation frequency and low power consumption. The VCO is a single stage circuit has a low phase noise due to reduced noise sources. The VCO is intended to operate as a frequency synthesizer in a PLL to generate local oscillator frequency (LO) for an acquisition system, providing in-phase/Q-phase outputs. The per...

Approximately 400,000 people die outside US hospitals or chronic carefacilities eachyear. While there has been some recent movement towards initiating procedures for prehospital Do Not Resuscitate (DNR) orders, the most common situation in the US is that emergency medical systems (EMS) personnel are not authorised to pronounce patients dead, but are required to attempt resuscitation with all of...

Bimlids ampstmg wntinues to be one of the more popular methods of biosolids management utilized in North America. According to the most recent BioCycle survey (Goldstein, 1995), 228 biosolids composting facilities were operational by the end of 1995 in the United States. The aerated static pile is still the most popular biosolids technology used with 101 facdities or 44% of the total being that...

Intermittent pneumatic compression (IPC) technolog ies are widely used in clinical populations to aid the reduction of limb oedema and for the prophylaxis of deep vein thromboses (DVT). IPC application within athletic populat ions is not however widespread. The main mechanism for the effectiveness of IPC is that it augments venous and arterial blood flow via the periodic inflation of external c...

In its various incarnations—Internet, intranet, extranet—its tentacles have spread to influence many facets of corporate and individual life. It follows that each extension of its capabilities has significant commercial and personal ramifications. The Web began as a medium ...

To obtain bulk? large-sized orthoferrite single crystals with different rare-earth elements a new crystal growth technology is proposed including modified Czochralski method and using no metal crucibles for melt suspension. For this purpose two unusual Czochralski method modifications are used. In the first one the melt of crystall~zed material 1s obtained at heating the upper surface of pol~cq...
