Cross-Reactivity Patterns of Contact-Sensitizing Methacrylates
Toxicology and Applied Pharmacology, 1998Methacrylates are well-known contact sensitizers with increasing frequency of contact leading to occupational skin disease. Here, we developed an animal model to facilitate studies on the sensitizing capacities and cross-reactivity patterns between four clinically most important allergens: methacrylate (MMA), 2-hydroxyethyl methacrylate (2-HEMA), 2 ...

Unusual Patterns in Contact Dermatitis: Medicaments
Dermatologic Clinics, 2009Allergic contact dermatitis to topical medicaments occurs often. Common medicaments associated with allergic contact dermatitis include topically applied antibiotics, antihistamines, nonsteroidal antiinflammatory drugs, anesthetics, and corticosteroids.

On biological pattern formation by contact inhibition
2012 American Control Conference (ACC), 2012Many patterning events in multi-cellular organisms rely on cell-to-cell contact signaling. We study a model which employs a graph to describe which cells are in contact, and examine its spatio-temporal dynamics. We first give an instability condition for the homogeneous steady-state.

Transcultural Patterns of Ritualized Contact Behavior
1971Man communicates with his fellow man, with speech but also with a number of expression-movements. Whether these signals belong to an innate repertoire of motor patterns which are not learned is a point of controversy. Gehlen is of the opinion that, except perhaps for a few reflexes of the newborn, there are no innate behavior patterns in man [14].

Lithography for patterning trench contacts
Microelectronic Engineering, 1992Abstract Lithography processes suitable for the patterning of buried trench contacts were tested for two different stacked capacitor cell concepts and evaluated with respect to process latitudes.

Clinical Pattern and Common Contact Sensitizers in Contact Dermatitis
Indian Journal of Applied Research, 2011Aim: Aim of the study was to find out the pattern and common contact sensitizers of contact dermatitis. Materials and methods: Hundred clinically diagnosed cases of contact dermatitis were assessed and subjected to patch testing. The reading was taken at the end of 48 hrs. The results were analyzed.

Reducing Contact Resistance in Graphene Devices through Contact Area Patterning
ACS Nano, 2013Performance of graphene electronics is limited by contact resistance associated with the metal-graphene (M-G) interface, where unique transport challenges arise as carriers are injected from a 3D metal into a 2D-graphene sheet. In this work, enhanced carrier injection is experimentally achieved in graphene devices by forming cuts in the graphene within

Patterns of Contact Attempts in Surveys
2014Survey participation is a type of social interaction between an interviewer and a respondent; by hypothesis, the way in which the respondent is successfully contacted, and agrees to cooperate, is a process of involvement in a social activity. Therefore, it is appropriate to use sequence analysis to understand how participants enter the survey according

An Equilibrium Model of Office Location and Contact Patterns
Environment and Planning A: Economy and Space, 1983In this paper, we develop an equilibrium model of office location, which explicitly considers the source of agglomeration economies and which sees firm location and contact patterns as jointly and endogenously determined. We solve the model explicitly for contact-benefit, facility-cost, and transport-cost functions representative of medium-sized US ...
