Of all the diseases studied in this course, malaria has been responsible for the most human suffering. It has evolved alongside humans, and impacted human biology as well as civilization. In the former case, this impact is evident in genetic diseases like sickle-cell anemia which, while increasing vulnerability to a host of other illnesses, has the advantage of conferring substantial resistance to malaria. In social terms, malaria's debili...more
Professor Saltzman introduces the basic concepts of renal physiology. Professor Saltzman first introduces the function and anatomy of the kidney. Special attention is given to the cell types and structural aspect of the nephron, the functional unit of the kidney. Filtration, secretion of toxic waste, and reabsorption of water, ions, and nutrients through the glomerulus and various segments of the nephrons is discussed in detail. Finally, P...more
Loss of sensory or behavioural functions as a result of brain damage or dysfunction can clearly have a significant negative impact on quality of life. What progress are we making towards repairing damaged brains and sense organs and treating mental disorders? This lecture will consider what therapeutic promise is currently offered by pharamacological, brain stimulation, brain training, neuroprosthetic (connecting artificial sensors to...more
Buffer: Vector vs Stack, Buffer as Linked List, Cursor Design, Use of Dummy Cell, Linked List Insert/delete, Linked List Cursor Movement, Compare Implementation, Doubly Linked List, Compare Implementation, Space Time Trade Off, Implementing Map, Simple Map Implementation: Vector, Map as Vector : Performance Implication, A Different Strategy
Class begins with discussion of students' answers to the two questions given as assignment in the previous lecture. Professor Saltzman talks about the basic concept of biomedical engineering and two separate aspects of it: gaining better understanding of human physiology and developing ways to improve human health. He then introduces the term homeostasis, and talks about parameters that are involved in controlling this state. Finally, the ...more
In the Apology, Socrates proposes a new kind of citizenship in opposition to the traditional one that was based on the poetic conception of Homer. Socrates' is a philosophical citizenship, relying on one's own powers of independent reason and judgment. The Crito, a dialogue taking place in Socrates' prison cell, is about civil obedience, piety, and the duty of every citizen to respect and live by the laws of the community.
Dr. Paul Ewald speaks about how several pathogenic viruses have evolved over time to break down the cell's barriers to several types of cancer. He suggests that further research will aid in the discovery of additional viruses linked to the causation of cancer. The lecture is concluded with a panel discussion with Gary Schoolnik and Stanley Falkow.
After a discussion of electrochemical cells, Professor Sylvia Ceyer defines the points of oxidation and reduction in a battery as the anode and cathode, respectively. She discusses the application of Faraday's Law and its relationship to electrochemical cells. Finally, the relationship between cell potential and Gibbs free energy is highlighted.
Former California State Senator Jackie Speier talks about the importance of standing up for a purpose in the course of life. She illustrates this idea by talking about people who initiated stem cell research and stood up against drunk driving. She insists that life requires one to step up.
Though some types of convergence devices become extremely popular, says Wirt, others never catch on. In certain cases, it is clear why the convergence device has never caught on (like a washer-dryer combo), and in others it is not so clear (like why people never use the built-in calculators on their cell phones), he adds.
Hawkins discusses how the cell phone took over mobile devices in the realm of personal computing. He projects where Handspring will go in the future with this transition.
According to Wirt, Europe is ahead of the US in cell phone use. An example of this is the popularity of Bluetooth in Europe and its relative obscurity in the states.
