Contact Angle Patterns on Low-Energy Surfaces
Advances in Colloid and Interface Science, 2014It is well-known that on a given low-energy solid surface, the contact angles of different organic liquids follow a regular pattern. The experimental evidence for this, and semi-empirical equations describing the pattern, are reviewed. Theoretical and computational efforts to explain the pattern are discussed, and a simplified analytical approach is ...

Contact sensitization pattern in 172 atopic subjects
International Journal of Dermatology, 2011AbstractBackground Some authors have claimed a decreased cell‐mediated immunity among atopic individuals, which would lead to observations of decreased rates of allergic contact dermatitis (ACD).Objectives The purpose of our study was to investigate contact sensitization patterns in atopic subjects compared with non‐atopic subjects.Methods Patch ...

Foot Contact Pattern following Selective Dorsal Rhizotomy
Pediatric Neurosurgery, 1995Fourteen ambulatory patients with spastic cerebral palsy were evaluated prior to and 6 months following selective dorsal rhizotomy. An instrumented gait analysis identified significant improvements in foot contact patterns, velocity and stride length. The high incidence of postoperative valgus, excessive dorsiflexion and persistent knee flexion during ...

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].

Patterns of prescribing extended wear contact lenses
Contact Lens and Anterior Eye, 2008Patterns of prescribing extended wear contact lenses in the UK were determined by mining through data gathered from annual contact lens fitting surveys conducted over the past 12 years. The increased rate of extended wear prescribing this century - which in 2007 had reached 7% and 19% of all soft lens new fits and refits, respectively - probably ...

Contact lens prescribing pattern in India—2011
Contact Lens and Anterior Eye, 2013To understand the pattern of prescribing contact lenses (CL) among Indian practitioners.Survey forms were sent to 257 practitioners across the country to collect information about their last 10 CL fits, location and type of practice, years of experience and educational qualification.

Photoresist Contact Patterning of Quantum Dot Films
ACS Nano, 2018Scalable and cost-effective protocols to pattern and integrate colloidal quantum dots (QDs) with high resolution have been challenging to establish. While their solubility can facilitate certain processes such as spin-casting into thin films, it also makes them incompatible with many conventional patterning techniques including photolithography that ...

Contact patterns in concanavalin A agglutinated erythrocytes
Cell Biophysics, 1991Agglutination of human erythrocytes by the lectin concanavalin A is enhanced when the erythrocytes are pretreated with neuraminidase, which removes sialic acids, or with pronase, which degrades both the glycophorins and band 3 protein. In the present work transmission electron microscopy of the enzymatically pretreated erythrocytes shows a regular ...

Advancing contact lines on chemically patterned surfaces
Journal of Colloid and Interface Science, 2004We report an experimental investigation on advancing contact lines of large drops spreading on chemically patterned surfaces. The model substrates were prepared using microphotolithography allowing precise control of the position and the size of the wettability patterns. Experiments were performed exploring different surface geometries: from ordered to
