The purpose of this study was to examine the effects of reductions in blood volume and associated oxygen-carrying capacity on the incidence of plateau at $$\dot{V}{\text{O}}$$ V ˙ O 2max. Fifteen well-trained athletes (age 23.3 ± 4.5; mass 77.4 ± 13.1 kg, height 180.1 ± 6.0 cm) completed three incremental cycle tests to volitional exhaustion, of which the(More)
The paper presents a method for the optimal design of oil production platforms and the systematic evaluation of the economic production capacity of a main field with an adjacent satellite field. The problem is formulated as a mixed-integer linear programming formulation. Continuous variables represent individual well, jacket and topsides costs. Binary(More)
INTRODUCTION Subdural haematoma (SDH) is rare following spinal anaesthesia and has not been reported previously in an infant. Non-accidental injury is the commonest cause of subdural haematoma in infants. METHODS We describe two cases of SDH following spinal anaesthesia in infants. RESULTS In both cases, forensic investigation was commenced and no(More)
This paper presents a general and systematic approach to address decisions in the design and operation of offshore oilfields. The approach is based on the formulation of mathematical models that are formulated to accommodate multiple production profiles. The profiles can be used to assess either the best strategy or, instead, possible implications in(More)
The study assessed differences in sensorimotor processing as reflected in measurements of saccadic latencies at 3 different stages in the menstrual cycle (menstruation, early luteal, and premenstruation) in naturally cycling women (n = 13), and at the same time intervals in women taking an oral contraceptive (n = 6), and male controls (n = 8). Subjects (M(More)
The author describes a system for testing patients with petit mal seizures. The system has the following advantages: 1) EEG paper speed is automatically increased from 2.5 mm/s to 25 mm/s when brainwave activity increases, with the increased speed maintainable for up to 4.0 sec after the last seizure burst. Control studies with constant speed and two-speed(More)
