Children are the future architects, mayors, doctors, and parents of the world of tomorrow, if they know what to do to reduce the impact of disasters, they will create a safer world. Each scen
Handbook for Teachers of Multi-Grade Classes: Improving Performance at the Primary Level
Multi-grade classes and single teacher schools have made it possible for many children in remote rural areas and communities to access education. However, the teachers teaching in these environments rarely receive training in how to deal with and manage the large numbers of pupils, of different ages and levels of learning, that they confront in their classes. These tools can assist teachers in this regard. This handbook comprises ten units, each one consisting of common experiences, case studies
Virtual Laboratory
The simulation program is based on the Nobel Prize winning Hodgkin-Huxley model for excitation of the squid axon. The program simulates an excised squid axon by applying stimuli or clamps after setting the environment of the axon, changing its properties, and/or adding drugs or toxins.
By using the program tools, experiments can be developed that explore a variety of nerve properties, ranging from classical phenomena such as threshold, summation, refractory period, and impulse propagation to mo

The user can investigate the effects of several variables on the effectiveness of the method and discover what happens when some of the basic assumptions of the model are relaxed or violated in some way. The user should gain some understanding of the sorts of things that complicate the application of the technique in situations that are
Food Interaction Study
This dataset comes from a study of 8 healthy males randomly assigned to a two-period crossover design, in which they either fasted and then ate, or ate and then fasted. They were given one dose of a drug, blood samples were collected and data on plasma levels were collected. Questions from this study refer to the absorption of the drug. A text file version of the data is found in the relation link.
Counting on Art
In Counting on Art, students will explore the paintings of Horace Pippin and Wayne Thiebaud and the mobiles of Alexander Calder to discover and practice math and visual art concepts.In Pippin's Story, young children (grades K–3) focus on a painting by African American artist Horace Pippin. They will learn how to "read" the clues in a painting and write a story about the work. Students will also solve counting and time problems and create their own "secret number" painting.Calder's Balancing Ac
Chemistry controlling post combustion hydrocarbon oxidation and homogeneous charge compression ignit
Environmental pollution and energy conservation have become of increasing concern over the past few decades. As one of the major sources of energy consumption and urban emissions, automobiles and light trucks (light duty vehicles) are under significant pressure to improve efficiency and reduce exhaust emission levels. While dwindling fuel reserves and greenhouse gas emissions are motivating factors behind long-term interest in increased efficiency, ambient air quality standards and associated pu
Factors influencing meaningful integration of technology into the high school curriculum: a case stu
Technology has significantly impacted American life. Children today grow up with a profusion of electronic wonders. Technology use in schools has lagged behind technological uses in society as a whole. As school districts strive to meet public expectations for technology use, school budgets devote significant dollars to technology related initiatives designed to improve student achievement. While money has been spent on technology, districts struggle to document improvement in student achievemen
Synthesis and characterization of the properties of Ti3SiC2/SiC and Ti3SiC2/TiC composites
In 1996, the ternary compound titanium silicon carbide (Ti3SiC2) was for the first timesynthesized as a single-phase, fully dense compound. Its characterization revealed aunique combination of properties. For its high fracture toughness, low hardness toelastic modulus ratio and excellent damage tolerance, it was dubbed a soft ceramic. Italso displayed good thermal shock and oxidation resistance. In this work, thereinforcement of this material with silicon carbide and titanium carbide particles w
Implications of resource management in La Parguera, Puerto Rico (The)
A recent rezoning of La Parguera, southwest Puerto Rico, as a tourist zone has resulted in an imbalance between development and appropriate resource management. Development associated with tourism is destroying the sub-tropical dry forest and adding pressure on the marine resources through increased boat traffic and marine structures. Declining water quality and benthic community health are two of the impacts seen in La Parguera associated with these land use changes. This study is three-fold. F

One Nation: Two Futures?
Since the mid-l970s, economic reforms have transformed China from one of the most egalitarian societies into one of the most unequal in the world. Wide disparities currently exist between the income levels of a relatively few rich and middle-class Chinese and their fellow citizens who number in the hundreds of millions. This "wealth gap" is particularly acute when one compares the incomes of urban and rural residents, between Chinese living in the interior of the country and those living in the
