When is a Compositional Effect not a Compositional Effect?
Quality & Quantity, 2007The question of compositional effects (that is, the effect of collective properties of a pupil body on the individual members), or Aggregated Group-Level Effects (AGLEs) as the author prefers to call them, has been the subject of considerable controversy. Some authors, e.g. Rutter et al.

Androgen effects on body composition
Growth Hormone & IGF Research, 2003Androgens are known to have a role in the body fat, muscle size, muscle performance and physical function differences seen between hypogonadal and eugonadal men. The results of investigations into effects of testosterone on body composition, fat metabolism and muscle anabolism are reviewed here. Testosterone dose-response relationships are presented in

Geometrical effect of composite fermions
Physical Review B, 1995According to recent theoretical and experimental work, the two-dimensional interacting electron gas in a strong magnetic field can be well described in terms of composite fermions for which the net magnetic field vanishes at a filling factor 1/2. We present a semiclassical theory of a geometrical effect of composite fermions that manifests itself by a ...

COMPOSITIONAL EFFECTS ON SURFACTANTFLOOD OPTIMIZATION
Proceedings of SPE Annual Technical Conference and Exhibition, 1979Abstract This paper presents results of phase behavior studies and oil displacement tests conducted in Berea sandstone cores which show that surfactant flood system based on optimal salinity design displace oil with different efficiencies.

Effective thermal conductivity of composites
International Journal of Heat and Mass Transfer, 2014Abstract The paper employs a theoretical model to evaluate the thermal conductivity of composites under two thermal assumptions which allow to solve the heat conduction equation. The composite is made of a ceramic-silica matrix and a fiber reinforcement. Three different materials are investigated as reinforcement, i.e. asbestos, steel and copper. The

Effect of puberty on body composition
Current Opinion in Endocrinology, Diabetes and Obesity, 2009Here we examine the effect of puberty on components of human body composition, including adiposity (total body fat, percentage body fat and fat distribution), lean body mass and bone mineral content and density. New methods and longitudinal studies have expended our knowledge of these remarkable changes.Human differences in adiposity, fat free mass and

Effect of Polymerization on the Color of Resin Composites
Operative Dentistry, 2022SUMMARY Objectives The initial shade of a resin-based restorative material should be the same as that after polymerization. In this study, the color changes of translucent and opaque composites from nine different brands were assessed after polymerization using a spectrophotometer and cross-polarization (CP) photography.

Searches for Composition-Dependent Effects
1999As we discussed in Chapters 1 and 2, composition-dependent effects are those (apparently) gravitational effects which depend on the chemical composition of the test masses. A simple example would be a difference in the accelerations of two dissimilar objects dropped from the same height, an experiment Galileo is reputed to have carried out. We noted in

Composite-fermion effective masses
Physical Review B, 1995Fractional quantum-Hall-effect features around filling factor ν=½ have been analyzed using the composite-fermion approach. Effective masses deduced from the temperature dependence of the Shubnikov–de Haas (SdH) oscillations, in agreement with other measurements, show a divergence as the filling factor approaches ν=½ and scale as (density)¹/².

Effect of Composition of Fibers on Properties of Hybrid Composites
International Journal of Manufacturing, Materials, and Mechanical Engineering, 2017Fibers embedded in the matrix of another material are the best example of modern day composite materials. Hybrid Composites made out of an amalgamation of Natural Fibers such as banana, jute, and coir along with glass fiber embedded in polymers have potential applications in automotive, aircraft and marine industries for their unique characteristics ...
