Composite interfacial layers containing micro-size and nano-size particles
Advances in Colloid and Interface Science, 2006Surface layers of micro- and nanoparticles at fluid/liquid interfaces in absence and presence of surfactants are of large importance in the process of re-discovering Pickering systems, i.e. emulsions and foams stabilized by particles. The surface pressure/area isotherms of such layers can provide information about the properties of the used particles ...

This chapter looks into the use of body composition information in nutrition by considering the key concepts of body size and composition. Nutrients in the diet are essential to provide the elements from which the human body is built, such as energy and cofactors.

Journal of Composites Technology and Research, 1989
The purpose of this note is to propose a relation somewhat similar to the size-strength relationship of brittle materials failing in tension in accordance with the Weibull theory. According to the failure theory of composites, a plot of the natural log of failure stress (ln σf) versus the natural log of volume (ln V) for a uniaxially reinforced ...

The silane/sizing composite interphase
Polymer Composites, 1993AbstractSilane coupling agents are but one of many ingredients in commercial sizings that are applied to glass fibers. The chemistry of a silane coupling agent alone allows it to react with both the glass fiber surface and the epoxy matrix to increase the fiber/matrix adhesion.

Protein size and cerebrospinal fluid composition
Klinische Wochenschrift, 1974The concentration ratios of several proteins between serum and cerebrospinal fluid (CSF) can be correlated more easily to hydrodynamic volumes than to molweights. Hydrodynamic radii were calculated from literature diffusion data and determined by analytical column chromatography and gel electrophoresis.

Reinforced polypropylene composites: Effects of chemical compositions and particle size
Bioresource Technology, 2010In this work, the effects of wood species, particle sizes and hot-water treatment on some physical and mechanical properties of wood-plastic composites were studied. Composites of thermoplastic reinforced with oak (Quercus castaneifolia) and pine (Pinus eldarica) wood were prepared.

Particle size and composition of composite dusts.
American journal of dentistry, 1990Inhalation of respirable crystalline silica dusts (sized between 0.5 and 5.0 micrograms) causes silicosis. Crystalline silica fillers are used in some composites and fine dusts/aerosols generated during high-speed finishing of these materials may be regularly inhaled by clinical dental personnel.

Forecasting Population Size and Composition
2017In this chapter, we present step-by-step examples based on commonly used procedures to develop forecasts using cohort change ratios (CCRs) and child-woman ratios (CWRs) in conjunction with the Hamilton -Perry (H-P) method. We next investigate the impact of adjusting H-P forecasts to independent total population controls because in rapidly growing ...

Body composition and size in sprint athletes
The Journal of Sports Medicine and Physical Fitness, 2017The aims of the present study were to assess competitive sprinters' body size and composition and to determine their impact on performance.Ninety-eight competitive male sprinters (100 m) participated in this cross-sectional study. A series of measurements was directly taken and data on muscular strength and power tests were self-reported.

Estimating Population Size and Composition
2017In this chapter, we explore the use of the CCR method for generating estimates for a current point in time. Specifically, we show that the CCR method can be used to generate estimates in conjunction with a general class of demographic methods known as “interpolation.”
