A reed-type shock gage is an instrument designed to measure the motion of a structure subjected to applied shock. It consists of a series of uniform cantilever beams each of which has a concentrated mass at one end and is clamped to the instrument frame at the other end. The natural frequencies of these beams or reeds are chosen so as to span the range of major frequency components of shock mot...

The purpose of this study was: to determine whether polishing standardized proximal root surfaces with dental floss, Superfloss, wood and plastic interdental cleaners, using a polishing paste, produces any significant change on root surface roughness; and to determine the effectiveness of different number of strokes in polishing. 80 tooth specimens were prepared, 10 in each of 8 sample groups. ...

Sir,?More than fifty cases treated by this method have more than proved its value. This treatment was introduced by Muldavin and Holtzmann (Lancet, 1938, i, p. 549) who cleaned up the wound with a saturated solution of urea, and after removing moisture and necrotic material applied pure urea to the wound itself and zinc cream to the adjacent skin. The wound was then covered with waxed paper and...

The method here described, which we have been using for some time in routine work, is a modification of the micro-method of May and others (1947), in which dilutions of the patient's serum are added to phenol-red-serum water on waxed slides, and incubated in capillary tubes. The dilutions of patient's serum and their addition to the medium are performed on a waxed glass plate which is incubated...

This paper considers the past and future of Psychology within Cognitive Science. In the history section, I focus on three questions: (a) how has the position of Psychology evolved within Cognitive Science, relative to the other disciplines that make up Cognitive Science; (b) how have particular Cognitive Science areas within Psychology waxed or waned; and (c) what have we gained and lost. After...

A technique to create an individually modified implant prosthetic abutment is described. An overcasting is waxed onto a machined titanium abutment, cast in titanium, and joined to it with laser welding. With the proposed technique, a custom-made titanium implant prosthetic abutment is created with adequate volume and contour of metal to support a screw-retained, metal-ceramic implant-supported ...

No significant differences were found in surface microflora of county-cured hams covered with stockinettes, barrier bags, or a coating of paraffin wax during aging, except for a reduction in mold growth on waxed hams. The incidence of Clostridium spp. was lost in all treatments. Micrococcus spp. and Streptococcus spp. were the most common contaminants, but caused no apparent spoilage problem in...

nterest in decompressive craniectomy (DC) to manage neurological emergencies including stroke has waxed and waned for decades. The best evidence for the use of DC is in patients with refractory cerebral edema related to large territory ischemic stroke. Although many publications have evaluated the role of craniectomy in managing neurological emergencies, none outline care priorities for patient...

DESCRIPTION A 29-year-old woman with bipolar disorder presented to the plastic surgery clinic with a gradually growing mass of the lower lip. The patient reported that the lesion was irritating and she frequently found herself biting it. It had waxed and waned in size over several years.
