Decays Let Physicists Look Inside Particles
These pages invite students to test various particles for their decay products. Most particles studied by physicists are unstable; they decay. That is, given enough time by itself, one unstable particle will fly apart into two or more particles. By carefully observing and logically classifying these decays according to some well-understood laws of nature, particle physicists have been able to explain much about the fundamental structure of matter.

SIMply Prairie: Prairie Advocates
In this multidisciplinary, inquiry-based project students prepare a plan and give a persuasive oral presentation to create a reconstructed prairie based on research. Teachers can use this unit with their students to justify enlarging or keeping an existing prairie. This project can serve as the organizing structure for prairie study where materials from units such as The Prairie – Our Heartland become research materials. It can be used in conjunction with the unit which is taught best in the f

AlgTop13: More applications of winding numbers
We define the degree of a function from the circle to the circle, and use that to show that there is no retraction from the disk to the circle, the Brouwer fixed point theorem, and a Lemma of Borsuk. This is the 13th lecture of this beginner's course in Algebraic Topology, given by Assoc Prof N J Wildberger at UNSW.

Antibody-protein interactions: benchmark datasets and prediction tools evaluation
Background The ability to predict antibody binding sites (aka antigenic determinants or B-cell epitopes) for a given protein is a precursor to new vaccine design and diagnostics. Among the various methods of B-cell epitope identification X-ray crystallography is one of the most reliable methods. Using these experimental data computational methods exist for B-cell epitope prediction. As the number of structures of antibody-protein complexes grows, further interest in prediction methods using 3D s

Cosmic Survey: What are Your Ideas About the Universe?
Lesson plans and activity composed of a three-part questionnaire that launches students on discussions about where objects in space are located, and when they were formed- an introduction to the concepts of structure and evolution of the universe. This astronomical image-sorting activity lays the groundwork for discussions about the size, scale and history of the universe. Use it as a front-end assessment of how students understand the universe. Recommended for teachers of Grades 6-12 and inform

Uniform convergence and pointwise convergence
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle. Uniform convergence is explained in terms of closed function balls and the new notion of sets absorbing sequences. The differences between the two types of convergence are illustrated with several examples. Some standard facts are also discussed: a uniform

Behavior of steel members with trapezoidally corrugated webs and tubular flanges under static loadin
Engineers have long realized that corrugated webs enormously increase steel girdersâ stability against buckling and can result in very economical design. Recently, the new idea of combining the tubular flanges with corrugated webs brought new issues of research. The objective of the research presented in this thesis is to investigate the behavior of steel members with corrugated webs and tubular flanges subjected to shear, bending, and axial compression. Relative buckling modes are also disco

Performative architecture as a guideline for transformation: Defense Line of Amsterdam
Performance as an architectural design paradigm has been emerging during the recent years. We have developed an understanding that we formalized as a taxonomy for performative architecture that considers performance from three points of view: health, safety and security performance; functional and efficiency performance; and psychological, social, cultural, and esthetic performance. This paper focuses on a design project that explores these ideas as a performative architecture proposal. The proj

Silal
This sample shows the typical structure of silal, irons with high Si content (5.5-7.9 wt%). It is a grey cast iron alloyed with 4-6wt% Si to provide good oxidation resistance. The high Si content forms a dense, adherent iron silicate surface film, which is resistant to oxygen penetration. The flake graphite iron Silal was one of the first heat resisting cast irons developed. Spheroidal graphite Si irons have higher strength and improved ductility. The structure shows cored dendrites of ferrite w

De cette expérience découlent des conséquences philosophiques, morales, pratiques et politiques qui comportent à la fois des lim
