Corneal Ulceration in South East Asia
This dataset has been added as an experimental use of Open Context for public health data sharing applications. Corneal ulceration is a major cause of blindness in many parts of the world, but in South East Asia the WHO estimates that there are as many as 12 million blinding ulcers every year in a population of 1.6 billion. Now that we know the main causes of these ulcers it is possible to prevent the occurrence of most of them with simple, grass-roots, public health measures. The development of
Penn State's Deer Research Center studies herd health options
White tail deer studies at Penn State can be traced back to the 1920s. Throughout the years, a variety of research initiatives have focused on improvements in nutrition as well as studies in buck and doe growth, healthy reproduction cycles and humane repellents and fencing to protect forest regeneration. Current research at the facility includes a collaborative effort with the National Wildlife Research Center in Fort Collins, Colorado. This study focuses on the overpopulation of deer herds in m
FACES: Studio Art
A nontraditional studio art major shares her experience as a busy mother who chose to study art at Del Mar College following a health crisis.
Study of Place: Ocean Currents Exploration
Each two-week module in the Study of Place curriculum is framed by an historical event that makes a connection between the physical environment and human activity. The activities focus primarily on physical and earth science content, geography, and inquiry skills. Assessments and scoring rubrics, including a pre-assessment that can be used for both modules, are embedded in each module, providing opportunities for tracking student learning. The Ocean Currents Exploration module is framed by Benja

The monosaccharide browser allows you to view space filling Fischer projections of monosaccharides. You can edit the structure and discover the correct name or you can select names from the classified index to discover the structure. The structure can be edited by choosing between aldose/ketose, number of carbon atoms between 3 and 6 and by clicking on carbon atoms to alter chirality. The Monosaccharide Browser can be used as a study aid in various ways. •Make a random monosaccharide by clic
3 The purpose of writing
Writing reports and assignments can be a daunting prospect. This unit is designed to help you develop the skills you need to write effectively for academic purposes. You will learn how to interpret questions and how to plan, structure and write your assignment or report.
This is a series of computer animations which demonstrate all the possible combinations of the ideal gas law or equation of state. Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and the volume which contains the gas. Careful, scientific observation has determined that these variables are related to one another and the values of these properties determine the state of the gas. In a scientific manner, we can fix any two of the fou
Northeastern Student-Athletes Post Strong Fall Semester Academic Performance
Northeastern University student-athletes continued a tradition of strong academic achievement during the fall 2010 semester, as 178 student-athletes earned a 3.25 grade-point average (GPA) or better, with seven earning a perfect 4.00 GPA.
The Lessons of 1704
In The Lessons of 1704, students learn the basic skills needed to do research and to "read" primary and secondary sources, to see what they can reveal about the cultural characteristics and attitudes of the English, French, and Native Americans in the Deerfield area in the late 17th and early 18th centuries. At the same time, they learn about the attitudes and behaviors of these three groups toward one another. Then, they use what they have learned to analyze the 1704 attack on Deerfield and the
Raid on Deerfield: the Many Stories of 1704
After several classroom discussions on anti-slavery issues, students will study the "American Anti-Slavery Almanac for 1838." The students will understand the importance and role of political cartoons during the anti-slavery movement. Students will observe and identify details in a political cartoon. Students will understand that there were people both in favor of and against slavery here in the North and how both sides are represented in the cartoon. Students will create their own anti-slavery
A Field Study of Interspecific Relationships
This exercise can be used to study population ecology, food webs and trophic levels. It is meant to give students a better understanding of the interrelatedness of organisms in a community by studying several common local relationships.
Introduction to Climate - Background Material
Climate is generally defined as average weather over a long period of time. A place or region's climate is determined by both natural and human-induced factors. Students can read an overview of Earth's climate and participate in activities which explain the following concepts: distinctions between weather and climate, variability of daily weather measurements compared to long-term climate data, how significant annual variability affects long-term climate averages, how Earth's climatic changes oc
A Holistic Approach to Teaching a Laboratory, Using Sea Urchin Development as an Example System
This exercise uses brainstorming, writing, and oral presentation techniques within the framework of a laboratory to illustrate the basic principles of early development. In groups, students learn how to identify a good model system (the sea urchin), isolate its gametes, mix some gametes from each sex, and study the ensuing processes of fertilization and development. After being introduced to the basic techniques, student groups design their own experimental approaches to further analyze these pr
Tracking Design Development through Decomposing Sketching Processes
We conducted a protocol study of the architectural sketching process. We decompose the process into process flows to explore the extent to which it expresses concept development in schematic and refined design phases. We track the development of design concepts in these phases by following the process flows of individual sketched strokes. We argue that each stroke drawn by the designer reveals a probability of an embedded concept, and that this concept is either promoted and propagated throughou
A Virtual Learning Environment for Doing Business on the Internet
The power of the new Communication and Information Technologies influences human life and economy so deeply that makes all of us learners both as individuals and members of (real or virtual) learning communities and learning organisations in a learning society. Looking back at the communication and information technology history we could clearly observe that the main attention of researchers and technologists has been gradually moved from hardware to software, next - to human-computer interface,
Basic Analysis: Introduction to Real Analysis
This free online textbook is a one semester course in basic analysis. These were my lecture notes for teaching Math 444 at the University of Illinois at Urbana-Champaign (UIUC) in fall 2009. The course is a first course in mathematical analysis aimed at students who do not necessarily wish to continue a graduate study in mathematics. A Sample Darboux sums prerequisite for the course is a basic proof course. The course does not cover topics such as metric spaces, which a more advanced course woul
Allometry: Size and its consequences or... Why aren't there 20 foot tall ants?
Evolution has resulted in changes in the sizes and forms of organisms. Everything about the biology of an animal, including its physiology, anatomy, and ecology, is influenced by its body size. Frequently there seem to be limits on the sizes that different organisms can attain, even when larger size might be thought to be evolutionarily advantageous. Often an increase or decrease in size is correlated with a change in proportions. Understanding the significance of a particular morphology or inte
Comparison of Approaches to a Multimedia Presentation
Two computer-based multimedia lecture presentations were developed using the same software but using two different approaches. Similar lecture material was used for both lecture presentations. Students found that there were considerable differences between the two lecture presentations. One lecture presentation was found to be very dynamic and interesting compared to the other. However, when videos showing applications of theory were supplied with the less interesting lecture presentation, stude

As a laboratory exercise that uses scientific techniques to add an investigative component to study the vascular system of plants.
