A Study of Gene Linkage and Mapping Using Tetrad Analysis in the Fungus Sordaria fimicola
This laboratory focuses on some aspects of spore color determination in the fungus Sordaria fimicola. Tetrad analysis of asci from a cross between strains mutant for two spore color genes is used to determine if the genes are linked and to map the location of each gene relative to the centromere. This laboratory is logistically simple and inexpensive, the data are relatively easy to collect, and the analysis facilitates a good understanding of meiosis and Mendel's principles of inheritance.

Aquatic Food Web Interactions: Microcosms as Lake Models
A laboratory exercise for increasing knowledge of trophic cascades in aquatic ecosystems has led to a better understanding of several basic ecological tenets, including competition, predation, and a variety of other community-level food web interactions using microcosms from whole water plankton collections.
Applying the Learning Cycle Approach to Digestive Systems and the Principles of Structure-Function a
The three parts of the learning-cycle strategy student exploration, concept formation, and concept application are the framework on which student understanding of 1 the interrelation of structure and function and 2 the coexistence of unity and the diversity among organisms are designed.
Blow, Crack, and Rage
Through a close reading of King Lear 3.2, students will explore both Lear's language and the effect of subsequent editorial intervention. Focusing specifically on punctuation within the King's famous "Blow winds" speech, students will learn to what degree punctuation affects one's understanding of the language and performance choices.
Washington Rules: America's Path to Permanent War
Washington stubbornly sticks to national security policies that don’t work, are devoid of moral considerations, sap the Treasury and rob future generations, says Andrew J. Bacevich. In a brief talk that leads to a candid and sometimes impassioned give and take with his audience, Bacevich describes a national security consensus
8 Summary
Energy from sources other than fossil and nuclear fuels is to a large extent free of the concerns about environmental effects and renewability that characterise those two sources. Each alternative source supplies energy continually, whether or not we use it. This unit considers one of these alternative sources, geothermal energy derived from the interior heat of the Earth, and the potential for this alternative to supplant fossil and nuclear fuel use to power social needs fast enough to avoid t
7 The pros and cons, and future of geothermal energy

2: Work done by gravity
From the moment that Galileo dropped two cannonballs of different sizes and weights from the top of the Leaning Tower of Pisa mankind has been fascinated by the impact of gravity. This Unit looks at gravity, its impact on objects and how the energy involved in the movement of objects is dispersed or stored.
3: Work done against gravity – gravitational potential energy
From the moment that Galileo dropped two cannonballs of different sizes and weights from the top of the Leaning Tower of Pisa mankind has been fascinated by the impact of gravity. This Unit looks at gravity, its impact on objects and how the energy involved in the movement of objects is dispersed or stored.
Absolutely Addition
Here are some fun games and activities to help with understanding and using addition.
What About Weather?
What would happen if you woke up this morning thinking it was going to be an ordinary day, but you looked outside and the weather was going crazy. The clouds were changing quickly and causing rain, hail, snow, and sleet. Lightning was striking all around your house. The sun was shinning one minute and the next minute it was dark as if it was the middle of the night because of the dark clouds. Hurricanes and tornadoes were being seen in places that have never seen them before. What would you do a
Science in Focus: Energy Workshop 2: Force and Work
Scientists define energy as the ability to do work. In this session, see how work is defined in physics and examine how energy and work are related.,Interviews with everyday people on the street and scientists explore the scientific meaning of work and its relationship to energy.
Architectural Computing in School and Real Designing
The existing system of architectural education ( including computer ) as has shown practice has appeared not absolutly perfect. It not capable to dynamic changes, active introduction of a new engineering and computer technologies, to realization about of the inquiries of a modern time. It suggest of a way of search of new models of computer training.
The computer education is represented by us as certain a universal system, which permits to solve the problem of arcitectural education at a higher
21H.221 The Places of Migration in United States History (MIT)
This course examines the history of the United States as a "nation of immigrants" within a broader global context. It considers migration from the mid-19th century to the present through case studies of such places as New York's Lower East Side, South Texas, Florida, and San Francisco's Chinatown. It also examines the role of memory, media, and popular culture in shaping ideas about migration. The course includes optional field trip to New York City.
5 Summary of Section 4
This unit looks at the human being in the context of an individual life cycle, examining some of the processes that contribute to the formation of a new person. After a brief discussion of historical ideas about human conception, and about contraception to the present day, we look at the cells involved in the conception and development of a new individual. Gamete production (that is, production of mature cells able to unite with another in sexual reproduction) in both men and women is introduced
PLoS Pathogens
From molecules to physiology, PLoS Pathogens publishes important new ideas on bacteria, fungi, parasites, prions, and viruses that contribute to our understanding of the biology of pathogens and pathogen-host interactions.
Lecture 9: Motion Capture
Dr Julian Morris on "Motion Capture". Over the past 25 years "motion capture" has grown from very small beginnings into a global market worth many £10 millions per annum, spanning applications in orthopaedics, sport, film, TV and computer games, and industry. The populist model of start-ups suggests an original stroke of technical and entrepreneurial insight, but this is misleading. The reality is a rather more interesting story of successive engineering responses to customer demand and competi
Tropical Ecology and Conservation
This seminar plus field work in Costa Rica is designed to give students with an in-depth understanding of tropical ecology and conservation biology. More specifically it provides students the opportunity to (1) read the original literature, (2) give oral presentations, (3) design and write a research proposal, and (4) gain hands-on research experience in Costa Rica. Here are what the students say are the highlights of the course: 1. Learning how to write a proposal and executing that project. 2.
Mesoscopic Physics
Mesoscopic physics is the area of Solid State physics that covers the transition regime between macroscopic objects and the microscopic, atomic world.The main goal of the course is to introduce the physical concepts underlying the phenomena in this field. Study Goals: Reach understanding of electronic properties of meso-size conductors, appreciate/recognize the role of classical and quantum processes, being able to explain electronic transport phenomena using simple physical concepts.Author(s):
