Methods are described by which the component groups may be extracted from polymodal size frequency samples by the use of probability graph paper. Four examples are given illustrating: the solution of a distribution with more than two modes and with only one exposed flank; the coordination of fish age determinations by the two methods, length frequency analysis and scale reading; a bivariate sample where the two means coincide though the standard deviations are different; a method of correcting for truncation.

Abstract We describe a useful technique to identify "fluoride-resistant" serum cholinesterase variants (E1uE1f and E1fE1f) by using the method of Garry to detect "atypical" variants and to measure serum cholinesterase activity [Clin. Chem. 17, 192 (1971)]. With butyrylthiocholine as substrate, sodium fluoride is used as a differential inhibitor in both Tris and phosphate buffer systems (50 mmol/liter, pH 7.4, 25°C). Fluoride inhibition values are plotted on two-dimensional graph paper, Tris plus sodium fluoride vs. phosphate plus sodium fluoride. Inhibition values for the "fluoride-resistant" and "atypical" variants are located in specific quadrants, which permits unequivocal identification of each variant. Examination of 836 Caucasian preschool children revealed a gene frequency of 0.0066 for the "fluoride" variant. No "fluoride-resistant" variants were found in 168 Negro preschool children examined.

Abstract We describe the measurement of rheumatoid factor in human sera with a rate nephelometer. The National Reference Preparation for Rheumatoid Factors is used to calibrate the assay in International Units. We used Hyland Positive Control, Level I, as a secondary standard. The standard curve is exponential, but is linear when plotted on log-log graph paper. Aggregated immune globulin (IgG) is the antigen used to detect rheumatoid factor (IgM-class antibody to IgG). The rate reaction measures the rate of increase in light-scatter by the antigen-antibody complexes; the reaction takes place in 17 to 20 s. Precision, linearity, and accuracy are excellent. Results agree well with those for a commonly used latex precipitation test. The advantages of speed, quantification in International Units, and superior discrimination of concentration as compared to serological titration provide a more reliable test for use in the diagnosis and treatment of rheumatoid arthritis.

The Many

In considering the mathematics program for elementary children, it is important for teachers to examine not only mathematical ideas but also the contexts within which such ideas are used. This usually means an examination of visual aids or tools of learning, since instruction in elementary grades depends upon the concrete to explain the abstract. With this in mind, one such tool that deserves special attention is graph, or squared, paper. Until one looks at the many possible uses of this visual aid, it may be taken for granted, and its applications remain sporadic and disconnected. This article is presented for the purpose of showing that graph paper is an educational device having few peers, especially from the points of view of economy, availability, and ease of use. An ordinary compilation of graph paper uses would be helpful to some degree, but what follows is a sequential development from the primary level through the upper elementary grades.

Maximum Minimum

To emphasize the distinction between perimeter and area, a useful lesson is one in which pupils use graph paper to draw many different rectangles of a given perimeter and then notice that these rectangles all have different areas. Since a lesson like this can be presented even in primarylevel classes, this discussion is limited for implicity's sake to integral values for the dimensions. For instance, rectangles of perimeter 16 could be 1 × 7, 2 × 6, 3 × 5, and 4 × 4. Students doing several such sets of rectangles with a given perimeter will discover the pattern: For a given perimeter, the square or the rectangle with length and width most nearly equal has the greatest area.

Graph paper can be used for concrete representations of both fractions and operations with fractions. The combined use of graph paper and an overhead projector makes the presentation even more convincing. The paragraphs that follow are a description of how I have used graph paper to illustrate the algorithm for the division offractions. The activities on division were preceded by activ ities that covered equivalent fractions, as well as addition and multiplication of fractions.

Human perception is finely tuned to extract structure about the 4D world of time and space as well as properties such as color and texture. Developing intuitions about spatial structure beyond 4D requires exploiting other perceptual and cognitive abilities. One of the most natural ways to explore complex spaces is for a user to actively navigate through them, using local explorations and global summaries to develop intuitions about structure, and then testing the developing ideas by further exploration. This article provides a brief overview of a technique for visualizing surfaces defined over moderate-dimensional binary spaces, by recursively unfolding them onto a 2D hypergraph. We briefly summarize the uses of a freely available Web-based visualization tool, Hyperspace Graph Paper (HSGP), for exploring fitness landscapes and search algorithms in evolutionary computation. HSGP provides a way for a user to actively explore a landscape, from simple tasks such as mapping the neighborhood structure of different points, to seeing global properties such as the size and distribution of basins of attraction or how different search algorithms interact with landscape structure. It has been most useful for exploring recursive and repetitive landscapes, and its strength is that it allows intuitions to be developed through active navigation by the user, and exploits the visual system's ability to detect pattern and texture. The technique is most effective when applied to continuous functions over Boolean variables using 4 to 16 dimensions.

Easy, accurate, inexpensive, and nondestructive methods to determine individual leaf area of plants are a useful tool in physiological and agronomic studies. This paper introduces a cost-effective alternative (called here millimeter graph paper method) for standard electronic leaf area meter, using a millimeter graph paper. Investigations were carried out during August–October, 2009-2010, on 33 species, in the Botanical garden of the Banaras Hindu University at Varanasi, India. Estimates of leaf area were obtained by the equation, leaf area (cm2) = x/y, where x is the weight (g) of the area covered by the leaf outline on a millimeter graph paper, and y is the weight of one cm2 of the same graph paper. These estimates were then compared with destructive measurements obtained through a leaf area meter; the two sets of estimates were significantly and linearly related with each other, and hence the millimeter graph paper method can be used for estimating leaf area in lieu of leaf area meter. The important characteristics of this cost-efficient technique are its easiness and suitability for precise, non-destructive estimates. This model can estimate accurately the leaf area of plants in many experiments without the use of any expensive instruments.
