Body composition in older adults can be assessed using simple, convenient but less precise anthropometric methods to assess (regional) body fat and skeletal muscle, or more elaborate, precise and costly methods such as computed tomography and magnetic resonance imaging.

Environmental Aging of Epoxy Composites
1983Fiber reinforced plastics (FRP) are increasingly utilized for structural application where their long-term properties are of primary importance. The strength enhancement and resistence to fracture which occurs when one combines high-strength fiber with low strength, low modulus polymer matrix, depends to a great extent on the polymer-filler interfaces.

he changes in composition of the aging T human body is of both gerontologic and geriatric interest and reflects genetic factors and environmental factors such as physical activity, nutrition, and disease, as well as the normal aging processes. In the study of normal aging, that is, aging per se, long-term trends in body compartments are important.

Anorexia, body composition, and ageing
Current Opinion in Clinical Nutrition and Metabolic Care, 2001Over the lifespan there is a decline in food intake. This has been termed the physiological anorexia of aging. It has many causes, including alterations in the gastrointestinal satiating system, the effect of elevated leptin levels, especially in men, and a variety of changes in central nervous system neurotransmitters.

Body Composition in Healthy Aging
Annals of the New York Academy of Sciences, 2000Abstract: Health risks in elderly people cannot be evaluated simply in conventional terms of body fatness or fat distribution. Elderly people have less muscle and bone mass, expanded extracellular fluid volumes, and reduced body cell mass compared to younger adults. These nonfat components of body composition play critical roles, influencing cognitive

Morphology and chemical composition of Ag/Sn/Ag interconnections
Journal of Microscopy, 2010SummaryThe main goal of the present contribution was to describe morphology and chemical composition of the intermetallic phases, which were formed during diffusion soldering process of the silver using tin. The Ag3Sn intermetallics is the main constituent of the joint after diffusion soldering at 235°C and 265°C.

Age Composition and Sexual Size Dimorphism of Albatrosses and Petrels Off Brazil
Marine Ornithology, 2009We present data on age composition and sexual size dimorphism (SSD) of albatrosses, petrels and shearwaters in southern Brazil for 301 birds of 14 species captured live at sea.

Synthesis of Ag-liposome nano composites
Journal of Liposome Research, 2010Silver nanoparticles were synthesized and stabilized by a simple, environment-friendly method in a liposomes structure. Liposomes were prepared by facing lecithin to the aqueous-phase solutions while stirring vigorously. The ratio of lecithin concentration to silver nitrate (K(Lec/Ag) = [Lecithin]/[AgNO(3)]) is the influencing factor in the synthesis ...

Composition of clinically aged amalgam restorations
Dental Materials, 1990Twenty-five amalgam restorations ranging in age from two to 25 years were obtained from five subjects. An electron microprobe was used to analyze the specimens for bulk elemental composition and phase composition, and the volume fractions of phases were determined by point-counting on back-scattered electron micrographs.

Energy Expenditure, Aging and Body Composition
The Journal of Nutrition, 1993We investigated the importance of adaptive variations in energy expenditure in the regulation of energy balance in young and elderly men of normal body weight leading unrestricted lives. Changes were measured in total and resting energy expenditure and body composition in response to overeating by approximately 4.2 MJ/d or undereating by 3.3 MJ/d for ...
