By the late 1960s, despite the ongoing Civil Rights movement, frustration over poverty, discrimination, injustice, and high unemployment among African Americans helped fuel unrest in many poor, black urban areas. On August 11, 1965, sparked by an angry confrontation between a white police officer and an African American motorcyclist, the Watts neighborhood in Los Angeles erupted in a large-scale civil disorder that lasted for six days and became known as the Watts Riots. Thirty-four people were
Phosphorescence lifetime imaging in turbid media
In this dissertation we explore the use of highly scattered photons in an analog of conventional emission tomography. Through this technique we quantitatively reconstruct images of the spatial distribution of oxygen in turbid media. We begin with the mathematical description of diffusive light propagation in highly scattering systems and solve the forward problem. Numerical methods by which the forward problem is inverted are introduced next, enabling quantitative spatial image reconstruction. T
Peptide-modified polymer for endothelialization
A functionalized polycarbonate material derived from tyrosine containing varyinglevels of free acid functionality along the backbone, poly(DTE-co-X%DT carbonate), hasbeen functionalized with a peptide to promote endothelial cell attachment and evaluatedas a potential synthetic vascular graft material. Lysine derivatives have been produced topromote the attachment of engineered peptides for promoting endothelialization.NMR has been used to analyze the initial structure of the poly(DTEC-co-X%DTC)
Lexical network size and connectivity in schizophrenia: effects on priming and cued recall
Aberrant semantic associative connectivity may be an underlying characteristic of the cognitive and symptom profile of schizophrenia. Words of varying network size (small or large) and connectivity (high or low) were used in lexical decision and cued recall tasks to test the hypothesis that word processing speed and recall in schizophrenia are modulated by increased activation of associative connectivity. Patients with schizophrenia and controls exhibited increased priming and higher probability
Media, speech act theory and computer supported cooperative work
Speech act theory, an influential trend in current CSCW research, has been used tomodel and develop a number of academic and commercial groupware systems.The question remains, however, concerning what happens when we use speech acttheory to analyze real world conversations in an organizational context. Thisdissertation recorded the face-to-face and telephone conversations and collectedemail over a six week period of a real world group of computer scientistscollaborating to produce a complex piec

Science in Focus: Force and Motion: Workshop 8. Bend and Stretch
We all expect a spring to stretch or compress when a force is applied, but forces can even deform solid objects like the floor or the top of a table. In this workshop, students in a high school classroom explore ideas about tension and normal force. By applying a force to a spring and measuring the distance the spring is stretched, the students calculate the force constant or stretchiness of the spring. Lecture demonstrations using student volunteers help to illustrate that even rigid objects be
MATH 1220 Calculus II
This course is the continuation of MATH 1210. Topics covered includes arc length, area of a surface of revolution, moments and centers of mass, integration techniques, sequences and series, parametrization of curves and polar coordinates, vectors in 3-space, quadric surfaces and cylindrical and spherical coordinates.

Sconill Letter, 1865 (page 1)
E. A. Sconill writes to Mrs. Brown at the request of her brother Henry B. McLaughlin "a prisoner of war confined at this post." Henry made application to take the oath of allegiance and Sconill believes he is sincere and should be released, but does not have the power to grant his release. On the side of the letter there is a note from President Lincoln dated January 12, 1865 stating that Henry McLaughlin may take the oath and be discharged.,Depot of Prisoners of War, near

Beem Letter, December 1863
This is David Beem's third Christmas letter to his wife since the war began. He speaks longingly of the turkey dinner he is missing at home. Christmas at the camp is just another day with no special meal. Many of the soldiers are drinking more whiskey than normal and celebrating Christmas by getting drunk and shooting their weapons.
Fast Scan Voltammetry
A short presentation of theory and practice of electrochemistry focused on use of microelectrodes and micro-bands in flow cells. Problems encountered are addressed and response characteristics discussed.
Funderstanding Roller Coaster
Provided by Funderstanding.com, the Roller Coaster Java applet Web site allows students to design their own roller coaster. After waiting for the program to load, users can change the height of two hills and the loop, the speed and mass of the car, and the gravity and friction being applied. After hitting the green start button, you get to see if the car flies off the track or doesn't make it through the loop. A simple but fun site.
not offended at anything that I have said or done you have not forgotten how to write have you then why is it I never hear from you anymore perhaps my letters have lost their power to please and to not interest you any longer if so I cannot help it I know there is but little merit in them but they are the effusions of an honest heart our Regiment is on Provost duty in Chattanooga our Brigade is stationed here Gen Wagner has command of the post our Brigade was first to enter the Rebel Strong
The History of Mass Spectrometry
This site provides a brief history of the development of mass spectrometry. The works of Thompson and Aston are presented along with a brief overview of the modern evolution of mass spectrometry. This site will be useful for beginning students interested in a historical overview of the field of mass spectrometry. This is an archived version of the site.
Future Directions in the Law Regulating Weaponry in Armed Conflict
A discussion on future directions in the law regulating weaponry in armed conflict to mark the release of Bill Boothby's new book Weapons and the Law of Armed Conflict. Bill Boothby has served for 27 years as an officer in the Royal Air Force legal branch. He developed and implemented the British system for the legal review of new weapons, and formed and led the team charged with conducting these reviews. Tom Porteus is London director of Human Rights Watch.
Soil community analysis along a salt gradient using denaturing gradient gel electrophoresis of PCR-a
Many studies of hyper saline environments have been performed, mainly on aquatic systems. However, the microbial community in terrestrial thallasohaline environments has not been studied extensively. To our knowledge, this is the first study of a natural terrestrial thallasohaline environment using polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE). We studied the great salt plains (GSP) for this purpose. The GSP is a perfect example of an extreme environment. The
Characterization of mechanical systems with real joints and flexible links
The field of multibody simulations has seen great strides in recent years. Most multibody simulations are carried out under the assumption that the joints involved are ideal. However many real joints are not ideal; they possess some clearance between their components. The existence of these clearances allows for the freeflight motion of some of the joint’s constituent components. This motion is usually followed by an impact leading to load amplification and chaotic motion. The effects of impac
Where the two kingdoms merge: the struggle for balance between national and religious identity among
When the German Reich was created in 1871, it was an artificial construct born of Hohenzollern power projection and not of nationalism. Otto von Bismarck’s Realpolitik used the power of nationalism to unite Germans behind the Kaiser, but also divisively to keep liberals and potential opponents of the Kaiser firmly divided. The Kulturkampf was one such set of policies that attempted to suppress Catholic political authority while dividing Germany’s religious groups against one another. The Kul
