Modeling of rolling element bearing mechanics. Computer program user's manual

This report provides the user's manual for the Rolling Element Bearing Analysis System (REBANS) analysis code which determines the quasistatic response to external loads or displacement of three types of high-speed rolling element bearings: angular contact ball bearings, duplex angular contact ball bearings, and cylindrical roller bearings. The model includes the defects of bearing ring and support structure flexibility. It is comprised of two main programs: the Preprocessor for Bearing Analysis (PREBAN) which creates the input files for the main analysis program, and Flexibility Enhanced Rolling Element Bearing Analysis (FEREBA), the main analysis program. This report addresses input instructions for and features of the computer codes. A companion report addresses the theoretical basis for the computer codes. REBANS extends the capabilities of the SHABERTH (Shaft and Bearing Thermal Analysis) code to include race and housing flexibility, including such effects as dead band and preload springs

Severe Antiretroviral Therapy-Induced Toxic Epidermal Necrolysis in a Child

Toxic epidermal necrolysis (TEN) is a rare and life-threatening condition characterised by extensive epidermal detachment and mucosal erosion. Adverse drug reaction is a strongly correlated causative factor and TEN is currently considered the most severe end of a spectrum of drug-induced mucocutaneous diseases, including Stevens-Johnson syndrome. Attaining an accurate and detailed patient history is critical for identifying potential causative agents, which can prove challenging; particularly in cultures such as that of Malawi. TEN lacks definitive management and the use of immunomodulation, such as with corticosteroids and intravenous immunoglobulin, remains controversial. We report a fascinating case of TEN associated with antiretroviral therapy. A 10-year-old female was given a combination of antiretroviral drugs (lamivudine, nevirapine and stavudine) as postexposure prophylaxis, having been raped. The child subsequently developed TEN and presented to our remote hospital in Malawi, where she was treated entirely with supportive therapy. This is an excellent example of difficult disease management in a limited-resource setting and provides reassuring evidence to clinicians of similar circumstance. To our knowledge, this is the first case report of antiretroviral therapy-induced TEN in a child

Patient Experiences in a Linguistically Diverse Safety Net Primary Care Setting: Qualitative Study

Background: The patient-centered medical home model intends to improve patient experience and primary care quality. Within an urban safety net setting in Northern California, United States, these desired outcomes are complicated by both the diversity of the patient community and the care continuity implications of a residency program. Objective: The objective of our study was to understand the patient experience beyond standardized satisfaction measures. Methods: We conducted a qualitative study, interviewing 19 patients from the clinic (English-, Spanish-, or Mien-speaking patients). Results: Some themes, such as the desire to feel confident in their doctor, emerged across language groups, pointing to institutional challenges. Other themes, such as distrust in care being provided, were tied distinctly to speaking a language different from one’s provider. Still other themes, such as a sense of powerlessness, were related to cultural differences and to speaking a language (Mien) not spoken by staff. Conclusions: Findings illuminate the need to understand cultural behaviors and interactional styles in a diverse patient population to create a high-quality medical home

Heat tolerance of short-beaked echidnas (Tachyglossus aculeatus) in the field

(1) Echidnas occur throughout the hot arid zone of Australia yet laboratory studies have concluded that they are ill equipped physiologically to manage T higher than 35°C. (2) Consequently, it is generally assumed that echidnas must rely on behavioural thermoregulation, being nocturnal in hot weather and seeking less extreme microclimates during the day. (3) By monitoring T of echidnas in the field and relating these to T within their day time shelters in Western Queensland during summer, this study showed that echidnas are able to tolerate T of 35-40°C in hollow logs for up to 10 h. (4) Further, as T remains < T in these situations, echidnas may have physiological mechanisms for dealing with the heat after all

Vocal communication in gibbons

Many non-human primates use vocal communication referentially and also use simple syntax and grammar. However, their comparative vocal repertoires are disappointingly sparse, with many researchers concluding that they have fixed vocal patterns made up of a limited number of discrete units used in a relatively small array of contexts (see McComb & Semple, 2005 for a review). Furthermore, these vocal patterns seem to be innate, under high genetic control with little evidence for vocal learning – something that humans are masters at (Janik & Slater 1997). This leaves us with some questions. Firstly, how did humans become so adept at producing and learning vocal sounds? And, secondly, are there any extant primate species with vocal behaviours that can be directly compared to our own?
