The Microbial Biorealm
The Microbial Biorealm is an informational site about microbes written by students for students. Hosted by Kenyon College, the site includes molecular and taxonomic information about microbes from all three domains of life. A comprehensive table lists the properties and characteristics of each domain of life while taxonomy pages list classification, description, significance, genome structure, cell structure, metabolism, ecology, isolation, cultivation, and references specific to individual taxa
This Web site from the National Center for Biotechnology Information (NCBI) offers a set of detailed tutorials to help users make full use of NCBI's bioinformatics tools. The tutorials, which target both new and veteran users, cover NCBI's BLAST and PSI-BLAST, Entrez data retrieval system, Cn3D molecular structure software, and more. Additionally, the Science Primer tutorial offers a "basic introduction to the science underlying NCBI resources" geared more toward the general reader.
Computational Biology: Bioinformatics Unit
This site features an undergraduate Computational Biology course as part of the Red Layer Microbial Observatory (RLMO) Project's Original Waksman/NSF supported courses and workshops. The course is offered as part of RLMO's education and outreach in order to better prepare students in the widely-applicable field of computational biology. Unit outlines, the syllabus, the project, and presentations and manuscripts about this curriculum can all be downloaded on site. Units include using NCBI, using
The material found at this site provides original, multidisciplinary, inquiry-based ideas to help enrich science teaching using the world famous Great Salt Lake as a springboard theme. During the lesson students will have the opportunity to view two types of algae (fresh water and Great Salt Lake species) under 400x magnification with a compound microscope. Students will make observations and record their observations on a recording sheet where they will describe what they see through drawing a
Soil Characterization Protocol
The purpose of this resource is to characterize the physical and chemical properties for each horizon in a soil profile. Students identify the horizons of a soil profile at a soil characterization site, then measure and record the top and bottom depth for each horizon. For each horizon, students describe the structure, color, consistence, texture, and abundance of roots, rocks, and carbonates. Samples are collected and prepared for additional laboratory analysis.
20.441J Biomaterials-Tissue Interactions (MIT)
This course covers the principles of materials science and cell biology underlying the design of medical implants, artificial organs, and matrices for tissue engineering. Methods for biomaterials surface characterization and analysis of protein adsorption on biomaterials. Molecular and cellular interactions with biomaterials are analyzed in terms of unit cell processes, such as matrix synthesis, degradation, and contraction. Mechanisms underlying wound healing and tissue remodeling following imp
Floor construction is the most serious activity in the building process serving as the main link between sub- structure and super-structure. Apart from the foundation, the floor of the building serves as the most immediate support for super-structure. The loads of the walls and columns and imposed loads are first transmitted to the floor before reaching the foundation concrete. The inability of a floor to support the above loads and onward transmission will indicate the ineffective nature of the
USGS Bedform Sedimentology
This site presents a collection of photographs, short movies, classifications, and computer-generated images for identifying various types of bedforms. Viewing of movies and 3D dynamic computer-modeled bedforms allows students to observe the creation, internal structure, and migration of bedforms through time. Photographs depict these processes in the real world. In addition, software for simulating ripple and dune bedforms and crossbedding is available for a free download. The site also feature
Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity. Teacher's guide available.
Decoding the Past: The Work of Archaeologists
This site introduces students to archeology -- the study of material remains to learn about past human experiences. This lesson (Grades 3-8) discusses various challenges of an archaeologist: locating a site that will yield clues about the people who once lived there, conducting excavations, and more. Students identify artifacts from a contemporary setting, describe the function of each artifact, identify methods for dating soil layers, and interpret soil profiles.
Inelastic Collision of Particles with Structure Model
The EJS Inelastic Collision of Particles with Structure model displays the inelastic collision between two equal "particles" with structure on a smooth horizontal surface. Each particle has two microscopic elements which interact through a massless spring of stiffness k and natural length L. The mass of one of the microscopic elements and the spring length of the connector spring can be changed via textboxes. You can modify this simulation if you have EJS installed by right-clicking within the p
QM Eigenstate Superposition Demo Model
The EJS QM Eigenstate Superposition Demo model displays the time dependence of a variety of superpositions of energy eigenfunctions for the infinite square well and harmonic oscillator potentials. One of the eleven pre-set superpositions can be selected via a drop-down menu with the resulting wave function shown in phase-as-color representation. A table of the expansion coefficients is shown and can be edited. The width of the infinite square well potential can be changed via a slider.
Lennard-Jones Potential Model
The EJS Lennard-Jones Potential model shows the dynamics of a particle of mass m within this potential. You can drag particle to change its position and you can drag the energy-line to change its total energy. The Lennard-Jones potential function is a reasonably accurate model of interactions between noble gas atoms. The binding energy epsilon is the depth of the potential well and minimum molecular separation are set equal to unity. This simulation uses uses a natural system of units the m
Radioactive Decay Model
The EJS Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events. It displays the number of radioactive nuclei as a function of time. You can change the initial number of nuclei and the decay constant as well as changing the plot to a semi-log plot.
Ejs Wave Representations Model
The EJS Wave Representations model displays two representations of a sinusoidal wave on a string. One shows a movie of the wave traveling along a string - you can think of this representation as a sequence of photographs. The second representation is a plot of the displacement as a function of time for two points on the string (you can select which two points to use). Using only these two representations, you can determine the values of many different parameters that describe the wave.
China - EU Relations in a Changing New World
The world today is undergoing tremendous development, changes and adjustments. The international community is facing increasing opportunities and challenges. The present international system and structure are not able to cope with this new situation fully and effectively, and reform is the general demand of the world people at large. Both China and UK are global actors of significant importance. How the two countries should behave in handling the situation? It is a fact that China and UK are dif
