Computerized analysis of concomitant contact allergens
Contact Dermatitis, 1991A statistical study was conducted on 3697 patch‐tested patterns in order to find any cross‐reacting or concomitant allergens, 44 correlations were found 3 were well‐known cross‐reacting substances (e.g., benzocaine and p‐phenylenediamine). 7 were unlikely, probably random, findings and the remaining 27 were considered to be either new Cross‐reacting ...

A retrospective analysis of contact allergy to lanolin
British Journal of Dermatology, 2001Lanolin is often stated to be an important sensitizer but some of the available literature is based on the analysis of high-risk patients.To analyse the frequency of contact allergy to lanolin (wool alcohols) in a central London teaching hospital patch-test population.Review of 24,449 patients recorded on our database during 1982--96 who were tested ...

Genital Contact Dermatitis: A Retrospective Analysis
Dermatitis, 2010many topical products are used in the genital region. Allergic contact dermatitis (ACD) may develop from product use or due to treatment of an underlying dermatosis.our goal was to identify the frequency of ACD and identify top allergens in the genital region.data were analyzed for 1,238 patients tested between January 1990 and December 2006.

Press- or shrink-fitting techniques are applied in various mechanical or forming components for the purpose of joining different components (for instance a shaft with sleeves or gears). Pre-stressing is used for forging or drawing dies in order to prevent excessive tensile hoop stress which causes their failure.

Plastic Analysis of Ice Contact Problems
Journal of Applied Mechanics, 1988The plane problem of a rigid stamp on a truncated wedge of rigid/perfectly plastic material is solved by the method of characteristics for a generalized von Mises yield function. Quadratic dependence of shear strength on mean normal stress is included in the yield function. For the corresponding three-dimensional contact problem upper bounds on contact

Tear Analysis in Contact Lens Wearers
Eye & Contact Lens: Science & Clinical Practice, 1986Tear analysis in contact lens wearers was compared with tear analysis in aphakics without contact lens wear and normal phakic patients. Subjects were divided into five groups: group 1, aphakic without contact lens; group 2, phakic with daily-wear hard contact lens; group 3, phakic with daily-wear soft contact lens; group 4, phakic with extended-wear ...

Analysis of the stochastic “unilateral contact” problem
Computers & Structures, 1977Abstract In the present paper the stochastic analysis of structures with “unilateral contact”-boundary conditions is considered. Initially the problem of “unilateral contact” is formulated in a variational inequality form. Then the theorems of minimum potential and complementary energy, which are derived to account for this type of boundary ...

Modal Methods for Contact Analysis and Contact Force Reconstruction
Problems of dynamic contact require an extraordinary number of solution iterations with very small time step and are—even in the age of massively parallel computing—a major impediment to efficient computational simulation of dynamics. To address this issue, we consider a modal approach to the contact problem: we consider a displacement basis that ...Daniel J. Segalman, Brian F. Feeny
