The star-construction test examines the patient s psychomotor function, recognition of shapes, and shortterm memory. A test sheet (s. fig. 10.4) is presented to the patient, who is requested to look at the five-pointed star drawn on it for about 10 seconds (E.A. Davidson et ah, 1956). (4) The test sheet is then covered or turned over. The patient is now asked to copy the star using 10 matchsticks, whereby the tips of the matches should form the pointed tips of the star. A lack of precision or errors in arranging the matchsticks and/or any confusion which arises during the test are rated as mistakes. In addition, the respective number of points can be recorded in the score sheet, (s. tab 10.10)...

If the F-test is significant then there is evidence of a quadratic effect due to at least one of the variables. With the present design, however, the investigator will not be able to determine which of the variables has a quadratic effect on the response. Additional experimentation, perhaps by augmenting the current design with some star points to construct a central composite design (see section on central composite designs below), will need to be conducted to fully explore the nature of the quadratic response surface. 

Abstract Although once it was thought that main-sequence stars are remarkably homogeneous with respect to their chemical composition, the upper main-sequence stars (30000 > Te > 7000) show a variaety of chemically peculiar stars besides the so-called normal stars. Those include the Am, Ap, A Bootis, He-deficient, and He-rich stars. This review summarizes the current data, which are necessary to construct and test the theoretical models of these stars. In the second half of the review we concentrate on Li. In the lower main-sequecnce stars abundances of Li have been determined in hundreds of stars. Some of the remarkable results are ... 

Prior to the tests, all the samples were dried in a vacuum oven at 80°C for at least 72 h to minimize the moisture effect and then transferred to a desiccator. Measurements were carried out on a cone calorimeter provided by the Dark Star Research Ltd., United Kingdom. To minimize the conduction heat losses to insulation and to provide well-defined boundary conditions for numerical analysis of these tests, a sample holder was constructed as reported in [14] with four layers (each layer is 3 mm thick) of Cotronic ceramic paper at the back of the sample and four layers at the sides. A schematic view of the sample holder is shown in Figure 19.12. Three external heat fluxes (40, 50, and 60kW/m2) were used with duplicated tests at each heat flux. 

Simulations, both MC and MD, have been used to test these scaling predictions and to determine other properties of a star polymer, including the static structure factor in the dilute limit. At present, it is not possible to simulate a melt or even a semi-dilute solution of many-arm star polymers due to the long relaxation times. For few-arm stars f 12) MC methods are clearly most efficient, while for large number of arms, MD methods work very well. For small /, the density of monomers of the star is low almost everywhere and static MC methods in which one generates the chains by constructing walks can be Using this method,...
