Thursday, November 13, 2003 Directions: The exam consists of 6 problems on pages 2 to 19 and work space on pages 20 and 21. Please make sure you have all the pages. Tables of Fourier series properties as well as CT Fourier transform and dt Fourier transform properties and tables are supplied to you at the end of this booklet. Enter all your work and your answers directly in the spaces provided on the printed pages of this book- let. Please make sure your name is on all sheets. You may use bluebooks for scratch work, but we will not grade them at all. all sketches must be adequately

production of plasma cells and memory B cells can be divided into three broad stages: generation of mature, immunocompetent B cells(maturation), activa- Initial Contact between b and T cells tion of mature B cells when they interact with antigen, and differentiation of activated B cells into plasma cells and memory B cells. In many vertebrates, ng humans B-Cell maturation and mice, the bone marrow generates B cells. This process

body. These organs can be classified functionally nto two main groups. The primary lymphoid organs provide appropriate microenvironments for the development and maturation of lymphocytes. The secondary lymphoid organs rap antigen from defined tissues or vascular spaces and are sites where mature lymphocytes can interact effectively with that antigen. Blood vessels and lymphatic systems connect these organs, uniting them into a functional whole Carried within the blood and lymph and populating the Macrophage Interacting with

Persons freedom to communicate, and their ability to do so effectively, has long been recognized as a crucial component of a society that respects human dignity and provides the conditions for humans to flourish. Government actions that suppress persons'speech and other forms of communication have been rightly subject to scrutiny and challenge Governments have also recognized the importance of affirmative steps to enhance persons opportunities for communications, such steps include improving education and supporting public forums. Communication is not only a personal and political good

In order to determine the interactions between copper atoms and rubber molecules, this article used X-ray diffraction to analyse the cure specimen of size materials mixed with copper powder for the first time, found the atomic nucleus distances between copper and atoms in rubber molecules were equal to 0.23169nm and 0.3043nm. 0.3043nm reflected the atomic distance between Cu and S under the action of Van der Waals force. 0.23169nm stated that there was chemical interaction between Cu atoms and rubber molecules

Chapter 11 Objectives After you have read and studied this chapter, you should be able to Include a FileDialog object in your program to let the user specify a file. Write bytes to a file and read them back from the file using FileOutputStream and FileInputStream. Write values of primitive data types to a file and read them back from the file using DataOutputStream and DataInputStream

In this paper the phase diagrams of LaCl3-LiCl and CeCl3-LiCl systems have been experimentally determined and theoretically calculated. Bath are simple eutectic systems. The eutectic points are at 25mol% LaCl3, 508℃ and 27mol% CeCl3, 494℃, respectively. The optimized phase diagrams and thermodynamical data of LaCl3-LiCl and CeCl3-LiCl systems with self consistency are a better basis for constructing ternary phase diagrams

The physico-chemical behavior of rare earth elements in low sulphur 16Mn steel and their ability to enhance the corrosion resistance of the steel in sea water studied in this paper. The results indicate that Ce and La in 16Mn steel all have the abilities such as deoxidation, desulphidation, refining grains and cleaning grain boundaries and matrix etc. The anodic and cathodic polarization curves show that the rare earth elements added in 16Mn steel enhance the corrosion resistance of the steel in sea water
