Abstract We present a new method for direct continuous-flow (AutoAnalyzer II) measurement of serum creatinine and uric acid. The manifold is simple, inexpensive, and can be constructed in the laboratory. Only 200 microliters of serum is needed; analysis rate is 60 samples per hour. The incorporation of sodium dodecyl sulfate and the simultaneous provision of blank subtraction make it possible to omit the dialysis step. Our method does not require the linearizer, since instrument response and concentration of creatinine and uric acid are linearly related to 200 and 120 mg/liter, respectively. The percentages of steady state, interaction, and recovery are acceptable, Precision is excellent and the results obtained from the new method correlate well with those obtained by the comparison methods. Interferences are few and, when encountered, are generally smaller than in the modified Technicon method. Marked hemolysis interferes only with the uric acid assay; marked turbidity has no effect on results for creatinine. Icteric serum with total bilirubin of 50 and 100 mg/liter interferes significantly with results for creatinine and uric acid, respectively, by the new method.

In this paper, we propose a new method for code optimization. This new method is based on backward data flow analysis, and the optimization is done on the source code level. First we design a tiny language to experiment with. Then, using data flow analysis, we set up some simultaneous equations and collect the liveness information for all program points. This is the basis for the optimization. Using this technique, some code can be safely eliminated without affecting the semantics of the code segment.

A new method for the preparation of metaphase chromosomes for flow analysis has been evaluated. It has been shown that this method, which involves detergent lysis of metaphase cells and polyamines to stabilize the DNA, yields lower coefficients of variation and background levels in the DNA histograms than is currently obtained by hexylene glycol based methods. A conventional flow cytometer (FACS-II) has been used to resolve the human karyotype into about 14 peaks after ethidium bromide staining and excitation with a relatively low level of illumination (0.4 W at 488 nm). Flow karyotypes have also been obtained from suspension cell lines, in particular from the mouse cell line, Friend 707/B10. The only disadvantage of this method is that the chromosomes are highly condensed and therefore banding studies on sorted chromosomes may not be possible.

To analyse the behavior of a solid particle in a vertical ascending air flow a series of studies have been carried out, both theoretical and experimental. This article presents a new method of imaging analysis of the behavior of a solid particle, in order to extend this study through experimental applications. The working algorithm implies the analysis of images in different positions of the solid particle in the vertical ascending air flow, analysis in relation to a reference image. By using the mathematical apparatus, i.e. Mathcad software, the movement of the solid particle in the air flow has been emphasized.

Multifilament Yarns

The properties of textured POY PES multifilament yarns are conditioned by texturing temperature, texturing speed, stretching degree and by the ratio of disc peripheral speed and yarn speed. In the paper attention is focused on crimping of yarns. New method for defining crimping limits is proposed. The method is based on the flow analysis of the force-elongation function. POY multifilament polyester yarns, having the fineness of 167f36x1 dtex were analyzed. The texturing of PES multifilament yarns was performed using different first heater temperatures (350 oC, 400 oC, 450 oC) and maintaining the constant temperature of the second heater (180 oC), then with different texturing speeds (500 m/min, 600 m/min, 700 m/min, 900 m/min, 1000 m/min, 1100 m/min), using different ratio of the disc circumferential speed to yarn speed (2.15, 2.20, 2.25) and at the extension degree of 1.665.
