Neurological aspects of sinoatrial heart block.
The symptoms of 100 patients with chronic cardiac sinoatrial disorder were analysed. The most common presenting features were syncope in 34 cases and dizziness in 22 cases. Over three-quarters of the patients had cerebral ischaemic symptoms at some stage of the disease. Diagnostic difficulties are often encountered and are illustrated by two case histories. Although sinoatrial disorder has been...
متن کاملAspects of Network Design
In this dissertation we study two problems from the area of network design. The first part discusses the multicommodity buy-at-bulk network design problem, a problem that occurs naturally in the design of telecommunication and transportation networks. We are given an underlying graph and associated with each edge of the graph, a cost function that represents the price of routing demand along th...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Randomized Block Design
Example It is common in nutrition studies to compare diets by feeding them to newly weaned male rats and measuring the weight gained by the rats over a 28-day period. The initial weight of the rats is an extraneous factor that is especially important as an influence on weight gain. Rather than randomly assign 10 rats to each diet, we first divide the animals into 10 groups of 3 rats each based ...
