The provision of aid in war zones can be fraught with political difficulties and may itself foster inequalities, as it is rare to be allowed access to civilians on both sides of a conflict. Over the past decade, a United Nations (UN) brokered agreement has allowed Operation Lifeline Sudan (OLS), a UN "umbrella" organisation, to provide the diplomatic cover and operational support to allow long ...

Hartmann’s procedure, first described by the French surgeon Henri Albert Hartmann in 1921, is one of the most commonly performed operations. This paper examines the history behind this operation and assesses its significance in modern surgical practice.

RPC latencies and other network-related delays can frustrate mobile users of a distributed file system. Disconnected operation helps, but fails to use networking opportunities to their full advantage. In this paper we describe partially connected operation, an extension of disconnected operation that resolves cache misses and preserves client cache consistency, but does not incur the write late...

A CMOS implementation of a high-gain current mode operational amplifier (opamp) with a single-ended input and a differential output is described. This configuration is the current mode counterpart of the traditional voltage mode opamp. In order to exploit the inherent potential for high speed, low voltage operation normally associated with current mode analog signal processing, the opamp has be...

It has become clear since the original studies of Cuthbertson (1930) that the change in metabolism after injury involves an alteration in the internal environment and in the composition of the body, which is reflected in fluid and electrolyte metabolism, energy and intermediary metabolism and endocrine function (Moore & Ball, 1952). This is appreciated by the patient as loss of weight, diminish...

In this paper, we investigate the collapsing of eight multioperand addition related operations into a single and common (3:2)counter array. We consider for this unit multiplication in integer and fractional representations, the Sum of Absolute Differences (SAD) in unsigned, signed magnitude and two’s complement notation. Furthermore, the unit also incorporates a Multiply-Accumulation unit (MAC)...
