An investigation of the effects of rapid skin heating on box beams loaded in bending

Description: Report presenting testing of two beams of three web types which were loading in bending and subjected to rapid skin heating at rates from about 50 to 70 degrees Fahrenheit per second. The investigation was meant to determine some of the effects that rapid skin heating would have on the buckling and failing strength of multiweb-wing structures. The three types of web tested included the channel web, corrugated web, and truss web.

Investigation of Reynolds number effects for a series of cone-cylinder bodies at Mach numbers of 1.62, 1.93, and 2.41

Description: From Summary: "An investigation of the Reynolds number for transition and the skin-friction drag at zero lift of eight cone-cylinder bodies having various fineness ratios has been made at Mach numbers of 1.62, 1.93, and 2.41 over a Reynolds number range from 0.3 x 10(exp 6) to 10 x 10(exp 6). The accuracy of the skin-friction data was not sufficient to permit any general conclusions to be drawn. The Reynolds number for transition was found to be dependent upon both the tunnel stagnation pressure and Mach number."

Skin Pigmentation Influencing Perception of Mexican-Americans

Description: Subjects were 101 Mexican-American adults (53 females, 48 males), age range 17-72, and most often were in the blue-collar job level. Instructions were that (a) 18 pairs of slides would be shown; (b) each slide would be projected for 15 seconds; (c) each of the two models was to be judged on intelligence, attractiveness, friendliness, happiness, and success; and (d) the rating scale would be marked corresponding to the left or right slide. Results indicated the lighter-skinned models were judged more favorably than the darker ones on all five dimensions. To the extent this study sheds light on an important cultural value, it is hoped the treatment of Mexican-Americans in therapy will be facilitated and improved.

Living with s(k)in: An analysis of tattoo removal.

Description: This paper investigates the role of tattoo removal in postmodernity. Specifically, I suggest tattoo removal is a technology of self in which the tattooed person can attain absolution from a "sinful" tattoo. This paper explores the construction of the confessional act in two parts: the construction of the confessing subject and the construction of the medical clinic as the confessor's listener. Using the texts medical offices place on the internet to advertise their services, I investigate the text's interpellation of subjects desiring tattoo removal. I then examine the construction of the clinic's status in the confessional act. Websites and brochures on gang tattoo removal provide a dialogue in which the clinic negotiates and attains its powerful position in the confessional act. The paper concludes by investigating the implications of the tattoo remnant, the material effects of the technology of self, and the benefits of studying the body-skin in rhetoric.

Using a Behavioral Treatment Package to Teach Tolerance to Skin Care Products to a Child with Autism: A Systematic Replication

Description: The purpose of this study is to investigate the effectiveness of a treatment package to teach a child with autism to willingly accept skin care products conducive to health and normal everyday living. The current study uses graduated exposure, modeling and contingent social attention to teach the child to accept the application of skin care products previously avoided. Results of the study showed that the participant tolerated criterion amounts of all target stimuli with both experimenter and parent. Follow-up probes revealed maintenance of the behaviors with only two out of the three target skin care products.

Skin Dose Equivalent Measurement from Neutron-Deficient Isotopes.

Description: Neutron-deficient-isotopes decay via positron emission and/or electron capture often followed by x-ray, gamma-ray, and 0.511 MeV photons from positron annihilation. For cases of significant area and/or personnel contamination with these isotopes, determination of skin dose equivalent (SDE) is required by 10CFR835. For assessment of SDE, we evaluated the MICROSPEC-2(TM) system manufactured by Bubble Technology Industries of Canada which uses three different probes for dose measurement. We used two probes: (1) the X-probe which measures lower energy (4 - 120 keV) photon energy distributions and determines deep dose equivalent, SDE and dose equivalent to eyes, and (2) the B-probe which measures electron (positron) energy distributions, and determines skin dose equivalent. Also, the measured photon and beta spectra can be used to identify radioactive isotopes in the contaminated area. Measurements with several neutron-deficient sources showed that this system provided reasonably accurate SDE rate measurements when compared with calculated benchmark SDE rates with an average percent difference of 40%. Variations were expected because of differences between the assumed geometries used by MlCROSPEC-2 and the calculations when compared to the measurement conditions.

The Effects of Environmental Consequences and Data Collection in the Behavior-Contracting Treatment of Obesity

Description: This study investigated the effects of environmental consequences and data 'collection in a behavior contracting procedure for obesity. Also, a validity study examined the GSR as a subject-independent-monitoring technique. Sixteen subjects matched on sex and percent overweight were assigned to one of three contract conditions or to a no-treatment condition. The Data Only Contract Group received consequences for data collection. The With Consequences Contract Group received consequences for data collection and behaviors relevant to weight loss. The Without Consequences Contract Group received no consequences for data collection or behaviors relevant to weight loss. The With Consequences Contract Group lost significantly more weight ( p ≤ .05) than the No Treatment Group. Specific effects were not determined. The results of the validity study suggest that the GSR may not be a valid instrument as a subject-independent-monitoring technique. Factors affecting the galvanic skin response's- effectiveness were discussed.

Particle Suspension Mechanisms - Supplemental Material

Description: This supplemental material provides a brief introduction to particle suspension mechanisms that cause exfoliated skin cells to become and remain airborne. The material presented here provides additional context to the primary manuscript and serves as background for designing possible future studies to assess the impact of skin cells as a source of infectious aerosols. This introduction is not intended to be comprehensive and interested readers are encouraged to consult the references cited.

Global Solar UV Index

Description: The Global Solar UV Index (UVI) described in this document is a simple measure of the UV radiation level at the Earth’s surface and an indicator of the potential for skin damage. It serves as an important vehicle to raise public awareness and to alert people about the need to adopt protective measures when exposed to UV radiation.

FURTHER STUDIES ON THE RELATIONSHIP BETWEEN EXPOSURE TIME AND DEPTH OF DAMAGE OF MODERATE AND SEVERE CUTANEOUS BURNS

Description: To extend our earlier studies on the relationship between exposure time and depth of damage of moderate and severe burns, injuries were produced by each of six radiant exposures delivered during varying exposure times. The exposures investigated were: 5, 8, 10, 13, 16, and 20 calories per square centimeter. Within this range, as the radiant exposure increased, the exposure time for the production of maximum damage also increased. Injury from a given radiant exposure was less with exposure times either longer or shorter than some immediate time which led to the most severe injury. The relationship between steam bleb formation and decreased depth of injury from short exposure times is pointed out. When the superficial layers of the skin become so hot that vaporization of tissue fluid occurs, energy which might otherwise damage the deep layers is diverted by the conversion of water to steam. For radiant exposures between 8 cal/cm/sup 2/ and 20 cal/cm/sup 2/ delivered with a square pulse, it is possible to predict with fair accuracy the exposure time which will result in the deepest burn.
