The Urban Homeless: Estimating Composition and Size
Science, 1987Although homelessness has been recognized as a serious and growing urban social problem, scientifically acceptable methods for estimating the composition and size of the homeless population have been lacking. A new research approach to estimating the size and composition of undomiciled urban populations is presented, and its utility is illustrated ...

Size, Weight and Chemical Composition
1972The measurement of copepods has been made by different people in different ways. The length of the metasome is perhaps the measurement used most frequently but often the total length, i.e. to the end of the caudal furcae, has been taken. This however has the disadvantage that if, as frequently happens, the urosome is bent, two measurements are ...

Body Size and 24-Hour Urine Composition
American Journal of Kidney Diseases, 2006Greater body mass index (BMI) is a risk factor for kidney stones. However, the relation between BMI and the urinary excretion of many lithogenic factors remains unclear.We studied urine pH, urine volume, and 24-hour urinary excretion of calcium, oxalate, citrate, uric acid, sodium, magnesium, potassium, phosphate, and creatinine in stone-forming and ...

Part Sizes of Smooth Supercritical Compositional Structures
Combinatorics, Probability and Computing, 2014We define the notion of smooth supercritical compositional structures. Two well-known examples are compositions and graphs of given genus. The ‘parts’ of a graph are the subgraphs that are maximal trees. We show that large part sizes have asymptotically geometric distributions.

Compositional Coinduction with Sized Types
2016Proofs by induction on some inductively defined structure, e. g., finitely-branching trees, may appeal to the induction hypothesis at any point in the proof, provided the induction hypothesis is only used for immediate substructures, e. g., the subtrees of the node we are currently considering in the proof.

7.4 Size Effects in Composites
2018The effect of test specimen size on the unnotched strength of continuous fiber reinforced composites is considered. The different fundamental failure mechanisms of fiber direction tension, fiber direction compression, and matrix dominated transverse tension and shear are discussed in turn.

Body Size and Composition of Perimenarchal Girls
Archives of Pediatrics & Adolescent Medicine, 1992A number of measurements are reported on a cross-sectional sample of girls who were studied at times ranging from 54 months prior to menarche to 82 months after menarche. Included are anthropometric measurements, lean weight, body fat, abdomen-hip ratio, skeletal size, bone age, muscle strength, and urinary hydroxyproline excretion. The years preceding
