Space Station based options for orbiter docking/berthing

Conceptual efforts to develop a Space Station based system for docking and/or berthing the NSTS Orbiter are described. Past docking and berthing systems are reviewed, the general requirements and options for mating the Orbiter and Space Station are discussed, and the rationale for locating the system on the Station is established. One class of Station-based system is developed in several variations and evaluated with respect to weight distribution, loads, safety, reliability, viewing, and maintainability. An evolutionary presentation of the variations provides insight into the development process and the problems encountered. An overall evaluation of the Station-based variations compared to an optimized Orbiter-based system demonstrates the potential benefits of this approach as well as the issues that must be resolved to realize the benefits

Leading with Integrity: the 28 Essential Leadership Strategies of Solomon, by Pat Williams

LEADING WITH INTEGRITY: THE 28 ESSENTIAL LEADERSHIP STRATEGIES OF SOLOMON. By Pat Williams. Uhrichsville, OH: Barbour (2005) Hardcover, 256 pages Written by prolific author, motivational speaker, and basketball manager Pat Williams, Leading With Integrity begins with a brief biography of Solomon and establishes a context for his leadership scenario. Following the biographical background chapters are 28 dense chapters highlighting leadership insights from Proverbs and Ecclesiastes—one key principle per chapter. Questions following each chapter encourage personal reflection and application of the principles discussed and suggest practical steps to implement them. Particularly nice is a summary chapter that lists each of the 28 strategies covered in the book with a brief corresponding exhortation

A Balancing Act: Division III Student-Athletes Time Demands and Life Roles

A majority of the research on student-athletes occurs at the Division I level, acid less is known about Division III student-athletes. The scant research addressing the experiences of Division III students-athletes focused on academics, campus involvement, development, and athletic identity (Griffith & Johnson, 2002; Heuser & Gray, 2009; Richards & Aries, 1993; Schroeder, 2000; Umbach, Palmer, Kuh, & Hannah, 2006). What remains unknown is how they manage life roles as Division III student-athletes.;This case study sought to address the time demands and life roles (e.g. athletics, family, friendship, religion, academic, and romantic interests) of student-athletes. Two private, Division Ill institutions in the Midwest were selected. A total of 21 student-athletes from both men and women\u27s basketball teams were interviewed. The findings suggest student-athletes are strained by time demands, yet have developed strategies to better manage their time. Family serves as a foundation and the most important life role for a majority of student-athletes. Teammates, coaches, and athletic involvement offer additional support as student-athletes transition through college. The life roles of religion and romantic relationships, however, were not seen as important for student-athletes. This research concluded that Division III student-athletes juggle multiple roles but their priorities change over time. of note, participant\u27s integrated roles over time and particular transition phases existed for students. Moreover, instead of border keepers vying to reinforce borders between roles, this study concluded that border bridgers existed instead that sought to aid students in blurring boundaries between their various roles. Male athletes were less able to describe how they managed time, whereas female athletes readily identified organizational strategies and stronger team bonds

Anaerobic Cultures from Preserved Tissues of Baby Mammoth

Microbiological analysis of several cold-preserved tissue samples from the Siberian baby mammoth known as Lyuba revealed a number of culturable bacterial strains that were grown on anaerobic media at 4 C. Lactic acid produced by LAB (lactic acid bacteria) group, usually by members of the genera Carnobacterium and Lactosphera, appears to be a wonderful preservative that prevents other bacteria from over-dominating a system. Permafrost and lactic acid preserved the body of this one-month old baby mammoth and kept it in exceptionally good condition, resulting in this mammoth being the most complete such specimen ever recovered. The diversity of novel anaerobic isolates was expressed on morphological, physiological and phylogenetic levels. Here we discuss the specifics of the isolation of new strains, differentiation from trivial contamination, and preliminary results for the characterization of cultures

Neutralizing Monoclonal Antibodies Reduce Human Cytomegalovirus Infection and Spread in Developing Placentas.

Congenital human cytomegalovirus (HCMV) infection is a leading cause of birth defects worldwide, yet the most effective strategies for preventing virus transmission during pregnancy are unknown. We measured the efficacy of human monoclonal antibodies (mAbs) to HCMV attachment/entry factors glycoprotein B (gB) and the pentameric complex, gH/gL-pUL128-131, in preventing infection and spread of a clinical strain in primary placental cells and explants of developing anchoring villi. A total of 109 explants from five first-trimester placentas were cultured, and infection was analyzed in over 400 cell columns containing ~120,000 cytotrophoblasts (CTBs). mAbs to gB and gH/gL, 3-25 and 3-16, respectively, neutralized infection in stromal fibroblasts and trophoblast progenitor cells. mAbs to pUL128-131 of the pentameric complex, 1-103 and 2-18, neutralized infection of amniotic epithelial cells better than mAbs 3-25 and 3-16 and hyperimmune globulin. Select mAbs neutralized infection of cell column CTBs, with mAb 2-18 most effective, followed by mAb 3-25. Treatment of anchoring villi with mAbs postinfection reduced spread in CTBs and impaired formation of virion assembly compartments, with mAb 2-18 achieving better suppression at lower concentrations. These results predict that antibodies generated by HCMV vaccines or used for passive immunization have the potential to reduce transplacental transmission and congenital disease

Simulations of the Dipole-Dipole Interaction Between Two Spatially Separated Groups of Rydberg Atoms

The dipole-dipole interaction among ultracold Rydberg atoms is simulated. We examine a general interaction scheme in which two atoms excited to the x and x(\u27) states are converted to y and y(\u27) states via a Förster resonance. The atoms are arranged in two spatially separated groups, each consisting of only one species of atom. We monitor the state mixing by recording the fraction of atoms excited to the y(\u27) state as the distance between the two groups is varied. With zero detuning a many-body effect that relies on always resonant interactions causes the state mixing to have a finite range. When the detuning is greater than zero, another many-body effect causes a peak in the state mixing when the two groups of atoms are some distance away from each other. To obtain these results it is necessary to include multiple atoms and solve the full many-body wave function. These simulation results are supported by recent experimental evidence. These many-body effects, combined with appropriate spatial arrangement of the atoms, could be useful in controlling the energy exchange among the atoms
