5.6 The importance of size and habitat The use of hibernation to gain energetic advantage must be weighed against a number of considerations, particularly animal size and behaviour, biogeographic distribution and habitat. Small animals, which can carry less fat and have a higher surface area to volume ratio and BMR, are more likely to lose energy as heat and in maintaining life functions if they do not use hypothermic strategies in winter. Few hibernating mammals have a total body mass greater than 5 kg. Indeed, in large animals t
3.5.1 Final arousal Emergence can be viewed as the final step in the series of periodic arousals. Instead of re-entering hibernation, the animal maintains the euthermic condition. The cue for maintaining this final arousal is probably not temperature, as some species emerge when T
a is well below zero. It is also difficult to see how arousal could be affected by daylength, since the hibernating animal is usually underground in a cavity or a burrow. Perhaps fat or food stores reach a minimum lev

Catholicism and Politics, Spring 2012
Catholicism and Politics poses the question, both simple and complex: How ought Catholics to think about the political order and political issues within it? The first part of the course will survey major responses to this question drawn from Church history: the early church, the medieval church, and the modern church. The second part applies these models to contemporary issues ranging among war, intervention, globalization, abortion, the death penalty, religious freedom, gender issues, and econo
The Rise and Fall of World Communism, Fall 2011
For most of the twentieth century, communist states, like the Soviet Union and China, represented the greatest political, ideological, and military challenges to the western world. But now, most of these states are gone; of those that still exist, only one (which one?) can credibly live up to the bloody examples set by Josef Stalin and Mao Zedong. In this course, we will draw upon an eclectic mix of approaches from political science, history, sociology, and political philosophy to make sense of
Nerve Racking
This lesson describes the function and components of the human nervous system. It helps students understand the purpose of our brain, spinal cord, nerves and the five senses. How the nervous system is affected during spaceflight is also discussed in this lesson.
South Korea-EU FTA in Seoul's hands
South Korea-EU free trade agreement clears final European hurdle, heads to Korean lawmakers for approval, but passage not guaranteed.
Bolivia building collapse
Rescue teams step up search for survivors who may be trapped under the rubble of a collapsed 10-storey building in Santa Cruz.
CAD and Management of Construction Projects
The increasing interest in computer-aided design (CAD) has prompted research that is aimed at identifying the opportunities for construction managers and building contractors. It has been found that the use of CAD systems in the U.K. is mainly confined to the production of detailed drawings. Indeed, most of the systems used are 2-D drafting tools and incapable of supporting the integration of even modest amounts of nongraphical (construction) data. On the other hand, many 3-D modeling systems ha
Geometric Searching In Extended CSG Models : Application to Solid Modeling and Viewing
In this paper, the CSG representation scheme is augmented with the 'cartesian product.' The sweep method of generating solids is encompassed by this 'Extended CSG' formalism. The point inclusion problem encountered in the area of geometric searching in computational geometry is discussed in the context to solid models represented by 'extended CSG.' A simple algorithm to solve it that has a time complexity O(n), where n is the number of primitives, is presented. Allowing for preprocessing and ext

Effects of drugs on pulsation rate of blackworms (Lumbriculus variegatus)
In this investigative lab, students observe blackworm pulsation rate in normal conditions and observe how pulsation rate is affected by drugs. This lab stresses the circulatory system, but can also be used for homeostasis, behavior, toxicology, and nervous system labs. Part I guides the student through blackworm handling procedures and initial observations of the blackworm's behavior and circulatory system. Part II is a student-led investigation in which the students design and run their own exp
9.14 Brain Structure and Its Origins (MIT)
Outline of mammalian functional neuroanatomy, aided by studies of comparative
neuroanatomy and evolution, and of brain development. Topics include early steps to a
central nervous system, basic patterns of brain and spinal cord connections, regional
development and differentiation, regeneration, motor and sensory pathways and
structures, systems underlying motivations, innate action patterns, formation of
habits, and various cognitive functions. Lab techniques reviewed. Optional brain

9.01 Introduction to Neuroscience (MIT)
This course is an introduction to the mammalian nervous system, with emphasis on the structure and function of the human brain. Topics include the function of nerve cells, sensory systems, control of movement, learning and memory, and diseases of the brain.

7.391 Concept-Centered Teaching (MIT)
Do you like teaching, but find yourself frustrated by how little students seem to learn? Would you like to try teaching, but are nervous about whether you will be any good at it? Are you interested in new research on science education? Research in science education shows that the greatest obstacle to student learning is the failure to identify and confront the misconceptions with which the students enter the class or those that they acquire during their studies. This weekly seminar course focuse
