See-saw nystagmus is a rare ocular abnormality, only 15 cases having been recorded to date (Maddox, 1914; Rucker, 1946; Larsen, 1957; Jensen, 1959; Smith and Mark, 1959; Mark, Smith, and Kjellberg, 1960; Lourie, 1963; Schurr, 1963; Kinder and Howard, 1963; Slatt and Nykiel, 1964; and Daroff, 1965). As initially described by Maddox (1914), the eye movements consist of regular reciprocating oscil...

We present an unusual case of cardiomyopathy in a two month old male infant with a grade-I systolic murmur. Echocardiographic examination disclosed left ventricular (LV), dysplasia with saw-tooth like inwards myocardial projections extending from the lateral walls towards the LV cavity. There was mild LV systolic dysfunction with apical hypokinesia. Cardiovascular magnetic resonance demonstrate...

See-saw ocular movements are described in two patients, one having obstructive hydrocephalus and the other a thalamic infarct. Electro-oculographic studies demonstrated that the eye movements in patient 1 moved in and out of phase at irregular intervals, in both a horizontal and a vertical direction. The disconjugate eye movements were exaggerated in bright light and less evident during fixatio...

Correctly selecting a saw for a job is one of the most critical decisions a sawmiller has to make. Even after the selection is made, the saw must be set up and operated within certain specifications for balanced performance. An understanding of the interrelationship of raw materials, end products, machinery, and the sawing process itself is essential. Often sawmillers operate their saws with le...

In this work, we discuss and demonstrate the principle features of surface acoustic wave (SAW) aerosol generation, based on the properties of the fluid supply, the acoustic wave field and the acoustowetting phenomena. Furthermore, we demonstrate a compact SAW-based aerosol generator amenable to mass production fabricated using simple techniques including photolithography, computerized numerical...
