Computed tomography demonstrated acute hydrocephalus less than or equal to 72 hours after subarachnoid hemorrhage in 24 (23%) of 104 patients. Of these 24 patients, six (25%) had no impairment of consciousness. In nine (11%) of the remaining 80 patients, acute hydrocephalus developed within 1 week after subarachnoid hemorrhage. With the exception of three patients, all 104 patients received ant...

This series of two papers (Parts 1 and 2) provides a rigorous comprehensive approach to the design of the principal software algorithmsutilized in modern-day strapdown inertial navigation systems: integration of angular rate into attitude, acceleration transformation/integration into velocity, and integration of velocity into position. The algorithmsare structured utilizing the two-speed updati...

Studies on the incidence and pathophysiology of hypotension in fulminant hepatic failure showed that 82 out of 94 patients developed arterial hypotension with a systolic blood pressure of less than 80 mmHg. Such episodes accounted for 16% of the total time spent in grade IV coma. Factors such as haemorrhage, cardiac or respiratory abnormalities, extracorporeal perfusion, or hypotension which oc...

Scene analysis is concerned with the reconstruction of d-dimensional objects, such as polyhedral surfaces, from (d− 1)-dimensional pictures (i.e., projections of the objects onto a hyperplane). In this paper we study the impact of symmetry on the lifting properties of pictures. We first use methods from group representation theory to show that the lifting matrix of a symmetric picture can be tr...

Background. Group A streptococcal (GAS) meningitis is rarely seen in the antenatal period, but it is associated with significant mortality. We present a case of a mid-trimester woman who developed fulminant meningitis following a rapid onset atypical presentation of infection with this organism. Case. A multiparous 23(+5)-week woman presented with a 10-day history of a non-productive cough asso...

We introduce a filtration on the simplicial homology of finite complex X using bi-colourings its vertices. This yields two dual theories closely related to discrete Morse matchings X. give an explicit expression for associated graded object these homologies when is matching Tait graph plane G, in terms subgraphs determined by certain G. then use one homologies, case where graph, define conjectu...

The conifer tree species Norway spruce ( Picea abies ), silver fir Abies alba ) and Douglas Pseudotsuga menziesii are important elements in composition forest management of Central European forests, but their potential to thrive under anticipated climatic changes is still debated controversially. This study contributes a multivariate analysis resilience components based on increment cores sampl...
