Classroom environmental conditions establish the social climate or atmosphere of a setting. Stern in 1970 stated that student's perceptions of classroom climate or learning environment are useful in predicting achievement. The purpose of this study was to determine if there was an effect between teaching style and student learning style on classroom environment. The population of this study con...

In order to meet the needs of performance-based seismic design, a new type of adaptive-slit shear wall that is easy to construct and behaves well under cyclic loading is introduced to improve the seismic performance of conventional shear wall structures. The seismic damage of an adaptive-slit shear wall develops gradually and it transforms from integral wall into slit wall. The mechanical chara...

In light of the massive developments in Information Technology (IT) in the past few years, there has been a recent debate in the literature on the economic impact of IT. Of particular interest has been the role of the ‘New Economy’ sectors (hardware, software, and communications) in bringing about economic growth and productivity revival in the United States. While on a much smaller scale, Egyp...

1.1. Sites. We begin with the underlying idea for a Grothendieck topology. Consider your favorite topological space X. Its topology, don’t use the Zariski topology, is determined by the partially ordered category UX consisting of all the open subsets of X ordered with respect to inclusion. In order to verify that a presheaf is a sheaf on X, we must first construct all possible coverings U = (Ui...

This study proposes a new type of calcium phosphate (CaP) scaffolds with a continuously gradient macro/microporous structure using the ceramic/camphene-based 3D extrusion process. Green filaments with a continuously gradient core/shell structure were successfully produced by extruding a bilayered feedrod comprised of a CaP/camphene mixture lower part and a pure camphene upper part. The extruded...

Complexity and abstraction provide a fertile frontier by which to express and experience complex systems in art, with integral challenges for abstract painting: Can we create complex art without a computer? What are the simple rules by which to create that art? The author proposes a model of the artist and her materials as a cellular automaton (CA) with eight simple rules. Experiments with the ...

In the process of developing innovative product concepts, user's needs and technology has been generally regarded as a major driver of innovation [2,9]. And although interaction, being the contact point of the actual user and products or services, has a very high significance, they have been overlooked because they were considered to be dependent factors of products and technologies. The reason...

BACKGROUND The molecular network sustained by different types of interactions among proteins is widely manifested as the fundamental driving force of cellular operations. Many biological functions are determined by the crosstalk between proteins rather than by the characteristics of their individual components. Thus, the searches for protein partners in global networks are imperative when attem...

We’ve read (and written) papers on how to write programs for multiplying polynomials, but a simple fact seems to have eluded some researchers, and we have not really emphasized it enough. Here it is: By using some extra memory you can simplify the program so much that it is very fast and hard to beat with any more sophisticated method. We explain why a very simple program is so fast that it pro...

Zero-divisors (ZDs) derived by the Cayley–Dickson process (CDP) from N-dimensional hypercomplex numbers (N a power of 2, and at least 4) can represent singularities and, as N , fractals and thereby, scale-free networks. Any integer >8 and not a power of 2 generates a metafractal or sky when it is interpreted as the strut constant (S) of an ensemble of octahedral vertex figures called box-kites ...
