BACKGROUND To determine whether monitoring end- tidal Carbon Dioxide (capnography) can be used to reliably identify the phrenic nerve during the supraclavicular exploration for brachial plexus injury. METHODS Three consecutive patients with traction pan-brachial plexus injuries scheduled for neurotization were evaluated under an anesthetic protocol to allow intraoperative electrophysiology. M...

Radio-frequency (RF) ranging can be an important aid to an integrated navigation system, providing a key element to updating location information when GNSS systems are unavailable, blocked, or otherwise denied. The majority of the recent literature on RF ranging aids has focused on ultra wideband (UWB) ranging methods, due to the increase in ranging precision that comes with increasing RF bandw...

In this paper we establish a one-to-one correspondence between S1-gerbes with connections, on the one hand, and their holonomies, for simply connected manifolds, or their parallel transports, in the general case, on the other hand. This result is a higher-order analogue of the familiar equivalence between bundles with connections and their holonomies for connected manifolds. The holonomy of a g...

The parallel linear transports defined by flat linear connection are axiomatically described. On this basis a number of properties, some of which are new, of these transports and connections are derived.

The (parallel linear) transports in tensor spaces generated by derivations of the tensor algebra along paths are axiomatically described. Certain their properties are investigated. Transports along paths defined by derivations of the tensor algebra over a differentiable manifold are considered.

the making of ear mould for hearing aids is generally considered to be a safe process. however, there are a few reported cases of complications caused during mould making. we report the case of a man with 69 years age, where the process of making the mould for a hearing aid led to the perforation of the tympanic membrane and pouring of mould material into the middle ear, necessitating surgical ...

Because of the increasing multidisciplinarity and multilinguality, communication problems in different technical fields grow more and more. Therefore, each technical field has its own specific language, terminology which is characterized by the different definition of terms. In addition to definition problems, there are also relation problems between terms. Among these problems of relation, the...

The growing elderly population will increase the need for assistive technology in the form of technical aids and housing adaptations to facilitate independence in activities of daily living. In this study, which was undertaken to facilitate a better understanding of the life-styles of the disabled elderly and the role of technical aids, 57 disabled persons over 74 years of age were studied. All...

The Unified Emergency Care System (UECS) provides an integrated system of medical support from point of injury to the time a casualty is handed over to specialist care within hospital. It enables personnel at all skill levels to deliver life-saving support to casualties with a broad range of acute injuries and illness. The UECS facilitates standardised training with each level building upon the...
