Information and telecommunications regulations and trends
The basic study material (compiled and aggregated from various sources and revised and in part written by Petrus H Potgieter) for a course Information and telecommunications regulations and trends at the University of South Africa (Unisa), available under the GnuFDL license. It discusses standards, the basics of telecommunications - including interconnect pricing - and industry issues. There is some emphasis on the South African context, but the largest part of the material is not country-specif
How to accelerate your Internet
Access to sufficient Internet bandwidth enables worldwide electronic collaboration, access to informational resources, rapid and effective communication, and grants membership to a global community. Therefore, bandwidth is probably the single most critical resource at the disposal of a modern organisation. The goal of this book is to provide practical information on how to gain the largest possible benefit from your connection to the Internet. By applying the monitoring and optimisation techniqu
Dynamic Remodeling of Individual Nucleosomes Across a Eukaryotic Genome in Response to Transcription
The eukaryotic genome is packaged as chromatin with nucleosomes comprising its basic structural unit, but the detailed structure of chromatin and its dynamic remodeling in terms of individual nucleosome positions has not been completely defined experimentally for any genome. We used ultra-high–throughput sequencing to map the remodeling of individual nucleosomes throughout the yeast genome before and after a physiological perturbation that causes genome-wide transcriptional changes. Nearly 80%
Internet Ancient History Sourcebook
The Internet Ancient History Sourcebook is a companion to the Internet Medieval Sourcebook and the Internet Modern History Sourcebook. The Medieval Sourcebook is both a classroom resource and the largest collection of online medieval texts. The Ancient and Modern Sourcebooks have a different role: since there are already ample online repositories of texts for these periods, the goal here is to provide and organize texts for use in classroom situations. Links to the larger online collections are
Cotton: Building a Better Plant
Plant genome research is already revolutionizing the field of biology. Currently, scientists are unlocking the secrets of some of the most important plants in our lives, including corn, cotton and potatoes. Secrets of Plant Genomes: Revealed! takes viewers on a lively, upbeat journey that explores how these plants got to be the way they are and investigates how we can make better use of them in the future. Plant scientists are hard at work--in the lab, in the field and at the computer--to increa

Aberrant mucin assembly in mice causes endoplasmic reticulum stress and spontaneous inflammation res
Background
MUC2 mucin produced by intestinal goblet cells is the major component of the intestinal mucus barrier. The inflammatory bowel disease ulcerative colitis is characterized by depleted goblet cells and a reduced mucus layer, but the aetiology remains obscure. In this study we used random mutagenesis to produce two murine models of inflammatory bowel disease, characterized the basis and nature of the inflammation in these mice, and compared the pathology with human ulcerative colitis.
A semaphorin code defines subpopulations of spinal motor neurons during mouse development.
In the spinal cord, motor neurons (MNs) with similar muscle targets and sensory inputs are grouped together into motor pools. To date, relatively little is known about the molecular mechanisms that control the establishment of pool-specific circuitry. Semaphorins, a large family of secreted and cell surface proteins, are important mediators of developmental processes such as axon guidance and cell migration. Here, we used mRNA in situ hybridization to study the expression patterns of semaphorins

Pulpit Rock, Cheaha State Park, Alabama
This image is a colorized photograph of Pulpit Rock in Cheaha State Park in Alabama. Postcard text: (back) Many beautiful Indian legends center about Pulpit Rock in Cheaha State Park, located approximately 22 miles from Anniston about midway between Anniston and Talladega. On a clear day one may see a seventy-five mile expanse of rugged mountainous territory. Here wild flowers: laurel, azaleas, moss and foliage add to its picturesqueness.
Main Building/Samford Hall, Auburn University 5
This image is a colorized photograph showing the Main Building, Alabama Polytechnic Institute, Auburn, Ala. Alabama Polytechnic Institute is the former name of Auburn University. The Main Building has been renamed Samford Hall and houses the university's administrative offices.
St. Martin's Church and Castle Trausnitz, Ave Maria Grotto, Cullman, Alabama
This image is part of a series of colorized photographs of the Ave Maria Grotto in Cullman, Alabama. Postcard text: (front) St. Martin's Church and Castle Trausnitz, Landshut, Bavaria. From folder: Brother Joseph Zoettl, O.S.B., a Benedictine monk at Saint Bernard Abbey, began experiments with concrete miniatures early in the 20th century. Abbot Bernard Menges, recognizing the popularity of Bro. Joseph's work, ordered construction of a park on the hillside in front of Saint Bernard College next
Confederate Veteran Reunion, 1906, Mobile Alabama 9
This image is from a set of black and white photographs taken to commemorate the Confederate States of America Veteran Reunion held in Mobile, Alabama, on November 20-22, 1906. The highlight of the reunion was a parade through the streets of Mobile. Major General Geo. P. Harrison was commander for the event. Colonel Harvey E. Jones was Adjutant General and Chief of Staff. Brigadier Generals commanding the brigades were Jno. W.A. Samford (1st), P.D. Bowles (2nd); J.N. Thompson (3rd), and J.W. Bus
Symptoms of Posttraumatic Stress Disorder in a New Orleans Workforce Following Hurricane Katrina
On August 29, 2005, Hurricane Katrina made landfall resulting in catastrophic damage and flooding to New Orleans, LA, and the Gulf Coast, which may have had significant mental health effects on the population. To determine rates and predictors of symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) in New Orleans residents following Hurricane Katrina, we conducted a web-based survey 6 months after Hurricane Katrina made landfall. Participants included 1,542 employees from
Attitudes Toward HIV Protease Inhibitors and Medication Adherence in an Inner City HIV Population
The objective of this pilot study was to examine attitudes toward protease inhibitors (PIs) among HIV-infected individuals and to assess the relationship between PI attitudes and adherence to PIs. Respondents were recruited from four AIDS service organizations in New York City; the total sample consisted of 97 HIV-infected individuals who were taking a PI. The sample consisted largely of African Americans and Latinos from inner city areas, and most had a low level of education. Adherence was sub
GeoMaths MathHelp Material

A mathematical glossary is also constantly available, providing a brief explanation of mathematical keywords and links to the relevant notebo
Evolution and the Nature of Science Institutes: Lesson Plans
This website provides access to lesson plans published by the Evolution and the Nature of Science Institutes (ENSI). Based on 32 key ideas of scientific thought, the ENSI program emphasizes the importance of teaching the nature of modern science before introducing the elements of evolution as an example of modern scientific thinking. This website features lessons in three categories - the nature of science, the origins of life, and evolution. Lesson plans are organized into eight sections includ
