Essential Science for Teachers: Earth and Space Science: Session 1. Earth's Solid Membrane: Soil
How does soil appear on a newly born, barren volcanic island? In this session, participants explore how soil is formed, its role in certain Earth processes, its composition and structure, and its place in the structure of the Earth.,Students and Scientists explore the question: What is soil?
TALAT Lecture 2110.02: Product information structure, business concept and LCA
This lecture gives a brief introduction to the product information structure, a sustainable business concept and Life Cycle; it presents the product and process "Generic Code" - the chromosomes; it generates interest about the concept of "Know Your Product", "Life Cycle Logistics", "Universal Virtues" and "Material/Component Hierarchical Structure" and their use creating a sustainable business concept; it imparts knowledge about Life Cycle Assessment. Some familiarity with QFD (Quality Functions
Classification of Precedents - A Hybrid Approach to Indexing and Retrieving Design Cases in SEED (a
An efficient indexing of past solutions is crucial to case-based design (CBD)
systems performing complex retrieval on large case-bases. This paper suggests a hybrid
approach to the indexing and retrieval of design precedents. The suggested approach
accounts for the issues of classification manifested in architectural discussions on type
and CBD literature. The indexing scheme integrates description-logic based
representation for classification and an object-based representation for precedents. T
Austenitic stainless steel
Shows the grain structure of an austenitic stainless steel NF709, observed using light microscopy on a specimen polished and etched electrolytically using 10% oxalic acid solution in water. Many of the grains contain annealing twins. NF709 is a creep-resistant austenitic stainless steel used in the construction of highly sophisticated power generation units.

As-cast wrought-grade aluminium alloy
The micrograph shows Al-Mg-Fe-Si containing < 1wt.% of each solute. No addition of grain refinement particles (e.g. TiB2). This micrograph illustrates one of the possible growth morphologies that a solidifying metal can adopt (c.f. micrograph 712). The dendritic structure is the result of instabilities in the solid-liquid interface during growth due to the rejection of solute into the liquid phase. Dendritic grains are more prevalent in alloys of high solute content and larger grain sizes.The Ba
Low magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, giving rise to the tri-cuspid cross section visible at the bottom of this image. The average co-ordination number for the nodes (where struts meet) is four, giving tetrahedral junctions.

Observations on Collaborative Design and Multimedia Usage in Virtual Design Studio
The virtual design studio (VDS) points to a new way of practicing and teaching architectural design. As a new phenomenon, little research has been done to evaluate design collaboration and multimedia usage in a distributed workplace like the virtual design studio. Our research provides empirical data on how students actually use multiple media during architectural collaborative design.

Penn State Odor Assessment Lab seeks to mitigate nuisance odor emissions from farm areas.
Once upon a time the boundary between farmland and housing developments was very distinct. Farmers in the past did not necessarily concern themselves with the odors that came from field operations, but as more people move to rural areas from urban sites, farmers and non farming residents have become next door neighbors and nuisance odors have become a problem.
Robin Brandt is the co-director of the Penn State Odor Assessment Lab in the Department of Agricultural and Biological Engineering. His
