Genetic Screening and Counseling is reviewed in this issue of Obstetrics and Gynecology Clinics, guest edited by Drs. Anthony R. Gregg and Joe Leigh Simpson. Authorities in the field have come together to pen articles on Contemporary Genetics Counseling: New Frontiers and Challenges, Newborn Screening, SMA Carrier Screening, Fragile X, Ashkenazi Jewish Screening in the 21st Century, Thrombophilia in Obstetric Practice, Microarrays in the Practice of Obstetrics and Gynecology, Cancer Genetic Screening, and Cystic Fibrosis.
Inside Out, Outside In takes familiar historical narratives and provides alternative readings for them. It endeavours to expand the parameters of comparative history by focusing on the economic, social, political and historiographical connections among societies, and by observing these intertwined histories from different vantage points. Iconoclastic, provocative, even quirky, Inside Out, Outside In takes us beyond culture and society into the imperial webs of association found inside and outside the discipline of history.
Sex, the Illustrated History: Through Time, Religion, and Culture, Volume II, continues a daring exploration of human sexuality from the ancient to the modern world. This volume explores the sexual beliefs and practices of the peoples of Asia, Australia, Africa, the South Pacific, and the indigenous Americas. Revealed are sexual practices and beliefs previously omitted or obscured from all historical telling. This work explores complex relationships between Eastern spirituality and sexuality. The author continues the exploration of religion's control over sexuality and the projection of women as both goddess and chattel. Sex, the Illustrated History traces sexual attitudes from the transcendent to the bizarre throughout the world's cultures. These pages share graphic erotic artworks as well as explicit literary excerpts painstakingly culled from the hidden treasure troves of cultures throughout history. The often-explicit illustrations are linked by historical and anthropological content, inviting the reader to experience sexuality through varied and often-shocking cultural lenses. Each volume contains over 250 erotically themed images that have been gathered by the author in his travels and studies of world cultures. This is an encyclopedic tour of the sexuality of humankind! Reviews "A startling achievement! Nothing like this has ever been published. A prodigious and iconoclastic odyssey into human sexuality through ages and cultures. A new light is cast upon lesser-explored topics in the history of sexuality, bisexuality, the subjugation of women, and the exploitation of women and boys. Hundreds of images of sexual and erotic life in various cultures help to tell this impeccably documented tale of human sensuality. Challenging and confronting, this book is sure to disrupt cherished beliefs about religion and sex" (Dr. T. W. Vickers). "Personally, I was enriched by this book and learned a vast amount of new sexual material. This book is both unsafe and pernicious if you share this most common superstition in our culture, the idea that words can be dangerous. I know John from the Berkeley days, and he worked with Timothy Leary and myself on the Exo-series of Human Evolution. I applaud his life's work" (Robert Anton Wilson).
A study has been carried out on Si/SiGe multi quantum well structures to determine their applicability as normal incidence infrared detectors in the spectral range of 2-12 micrometers. The research effort was primarily experimental, however, extensive calculations were performed to initially explain the experimental data and then used to design subsequent structures. Multiple quantum well structures grown on both Si001 and Si110 substrates via molecular beam epitaxy were studied by photoluminescence, absorption, and photoresponse measurements over a wide parameter space. Variables included quantum well depth and width, well doping, number of wells and growth temperature. Well widths were varied from 20A to 50A, Ge composition from 10% to 60%, boron doping from 1 x 10(exp 18) cm(exp -)3 to 8 x 10(exp 19) cm(exp -3), number of wells from 5 to 30 and growth temperature from 550 to 710 deg C. Calculations using k.p theory and the envelope function approximation were performed to determine the position of the bound states in the wells, the amount of band mixing and the transition strengths for bound-to-bound transitions for Si001/Si sub (1-x)Ge sub x, Si110/Si sub (1-x)Ge sub x and GaAs/AlGaAs quantum well structures. The Si110 structures have more allowed energy bands which are significantly mixed. A comparison was made between Si001/Si sub (1-x)Ge sub x, Si110/Si sub (1-x)Ge sub x and GaAs/AlGaAs quantum well structures designed to operate in the 8-12 micrometer region, and all three showed comparable momentum matrix elements.
