Dr. Beam was born and raised in Orrville, Ohio. While in high school, he competed in football, wrestling and golf and played trumpet in the jazz band that toured the U.S. and Europe. He received his B.S. in biology from the College of Wooster, a small liberal arts college in Ohio. During his undergraduate study, he spent one summer in Vienna, Austria studying art history and German. He completed his graduate work and obtained his Ph.D. in exercise physiology from The Ohio State University. While a graduate assistant at Ohio State, he was responsible for performance testing of all the athletes including football, basketball, baseball, swimming, ice hockey and more. It was a wonderful experience working with so many talented collegiate, Olympic and future professional athletes. Dr. Beam joined the faculty at Cal State Fullerton in 1983 and the following year began directing the Exercise Physiology Lab and the Physical Performance Program. Under Dr. Beam's guidance, over fifty graduate students have completed their master's degrees and most are now active in the community working and teaching within the fitness/wellness profession. He also previously served as President of the Southwest regional chapter of the American College of Sports Medicine (SWACSM), and as the regional chapter representative to the ACSM Regional Chapters Committee. Bill currently lives in Placentia, California with his wife Terri, who teaches Chemistry at Mt. San Antonio College, and their two children Danny and Sara. Bill has commuted primarily by bicycle during his time at CSUF and enjoys cycling, jogging, swimming and playing sports with the family.
BioLabs Laboratory instructors often face a special set of challenges. BioLabs helps address those challenges by providing laboratory instructors and coordinators with a source for basic information on suppliers, best practices, professional organizations and lab exchanges.
Atlas to Human Anatomy, 0-697-38793-3, by Dennis Strete, McLennan Community College and Christopher H. Creek, takes a systems approach with references to regional anatomy, thereby making it a great complement to your regular course structure, as well as to your laboratory.
As with any topical book dealing with expanding areas of molecularbiology, Intervening Sequences contains some dated information. Theobjectives of the editors, however, to explore the evidence that introns andsplicing have played a role in genic evolution, to review RNA splicing, andto examine the role of introns in gene expression, are well served inchapters examining these issues from different scientific perspectives.
In one of the less technical but more thought-provokingpresentations, W. F. Doolittle carefully and logically sets out evidence forthe introns-early and introns-late hypotheses of intron origins, and, indoing so, covers some fascinating aspects of intron biology and evolution.He frames the thematic currents in the book as questions: Do exons shuffle?Can introns be gained or lost? How do intron structure and evolutionarytaxonomy shed mutually illuminating light on each other? Does a rationaleexist for the proposed importance of introns to the rate of evolution?Obviously, the definitive answers are not in, but Doolittle's chapterruns these to ground in a lucid and entertaining discussion. He suggeststhat molecular biologists' revolutionary arguments for the utility ofintrons may be on target, but he also suggests multilevel subtleties thathave yet to be appreciated.
A noticeable chromatic diversity is observed between images, especiallyregarding the red hues, as well as differences in contrast and brightness.These characteristics, which vary from one image to the other, make itdifficult to follow usual data-processing methods [14-16]. An approach based on the definition of a scale of reds would beproblematical in the present case. As a matter of fact, this type of methodrequires the manual correction of each image, which quickly becomes timeconsuming when a large number of images has to be analyzed. Furthermore, acolor scale is complex to define since the differences between the types ofpatterns (intense rosacea, light rosacea and noise) are difficult to quantifywith precision.
The choice of RGB coding may be criticized, a laboratory coding wouldprobably be more appropriate as soon as the images are stored, in order toharmonize the colorimetric spaces and avoid conversions. The comparison ofthe results with those obtained with chromametry measurements (where thecharacterization of the skin color is usually based on the laboratoryrepresentation) could then be considered.
The neural network learns to classify these samples correctly. The 200patterns that compose the learning base (100 patterns of rosacea and 100patterns of background noise) are selected from representative images. Theselection is made manually by pointing out the pixels located around eachspot. 076b4e4f54
