Low pressure leakage in anaesthetic machines

Development of anaesthetic machines.

It is abundantly clear that, during the past few years, there has been a remarkable resurgence of interest in all aspects of the history of anaesthesia, and not least in that of anaesthetic apparatus. Not only academic departments of anaesthesia, but also smaller general hospitals are now admitting to some form of collection of historical anaesthetic apparatus which has been garnered by devotee...

Circumstances of leakage related to low urethral closure pressure.

PURPOSE We determined whether urinary leakage in some circumstances is associated with intrinsic sphincter deficiency, defined by a low maximum urethral closure pressure of 30 cm H(2)O or less, in women presenting for urinary incontinence. MATERIALS AND METHODS We retrospective analyzed the records of 100 consecutive women who underwent complete urodynamic evaluations for complaints of urinar...

The hidden dangers of anaesthetic machines.

Robust Low-Leakage Circuits

Problem: While the aggressive scaling of CMOS technology to ever smaller dimensions has enabled higher performance and integration levels, it has given rise to a plethora of new problems in the design of integrated circuits [1-4]. Reduced threshold voltages and gate oxide thicknesses have caused an alarming increase in subthreshold source-drain leakage and gate leakage power dissipation in both...

Preventing Information Leakage from Virtual Machines’ Memory in IaaS Clouds

Infrastructure as a Service (IaaS) provides virtual machines (VMs) to the users and its system administrators often manage the user VMs using privileged VMs called the management VM. However, the administrators are not always trustworthy from users’ point of view. If the administrators allow outside attackers to intrude in the management VM, the attackers can easily steal sensitive information ...
