A 17 year old with isolated proximal tibiofibular joint arthritis
Canna Scott W,Chauvin Nancy A,Burnham Jon M
Pediatric Rheumatology , 2013, DOI: 10.1186/1546-0096-11-1
Abstract: The proximal tibiofibular joint (TFJ) is rarely affected in rheumatic diseases, and we frequently interpret pain of the lateral knee as the result of overuse or trauma. Nonetheless, the TFJ is a synovial joint that communicates with the tibiofemoral joint in a proportion of patients. While proximal TFJ arthritis has been rarely associated with existing spondyloarthritis, isolated TFJ arthritis as the presenting manifestation of spondyloarthritis has not yet been described. Here, we report the clinical and radiographic presentation of an adolescent with chronic proximal TFJ arthritis heralding spondyloarthritis highly suggestive of ankylosing spondylitis.

Doocy,Shannon; Rofi,Abdur; Moodie,Claire; Spring,Eric; Bradley,Scott; Burnham,Gilbert; Robinson,Courtland;
Bulletin of the World Health Organization , 2007, DOI: 10.1590/S0042-96862007000400012
Abstract: objective: nine tsunami-affected districts in aceh, indonesia, were surveyed between february and august 2005 to characterize tsunami mortality. methods: the surveys employed a two-stage cluster methodology with probability proportional to size sampling, and encompassed 1653 tsunami-displaced households with a pre-tsunami population of 10 063 individuals. findings: of the original pre-tsunami population, a total of 1642 people, or 17%, were reported as dead or missing in the tsunami. crude mortality rates in the four survey areas ranged from a high of 23.6% in aceh jaya district on the west coast to 5.3% on the east coast. age-specific mortality rates followed a similar pattern across the four survey areas, with the highest mortality concentrating in the youngest children (aged 0-9 years) and oldest adults (70+). the risk of mortality was significantly greater among females than males; this difference was most pronounced among individuals between ages 10 and 69 years, and diminished among younger and older age groups. conclusion: mortality risk in the 2004 asian tsunami varied by geographic location, age and sex. the districts of aceh jaya, banda aceh and aceh besar experienced the greatest mortality. risk of death was highest among females, and among the oldest and youngest population subgroups. while the full human impact of the asian tsunami in aceh province, in terms of lives lost or damaged, may never be fully measured, the resulting female deficit will likely be the tsunami?s most deeply felt and prolonged impact.

Modelling of optical traps for aerosols
D. R. Burnham,D. McGloin
Physics , 2010, DOI: 10.1364/JOSAB.28.002856
Abstract: Experimental observations suggest that there are differences between the behavior of particles optically trapped in air and trapped in a liquid phase. We present a modified version of Mie Debye Spherical Aberration theory to numerically simulate such optical system in attempt to explain and predict these effects. The model incorporates Mie scattering and focussing of the trapping beam through media of stratified refractive index. Our results show a geometrical optics approach cannot correctly describe our system and that spherical aberration must be included. We successfully qualitatively explain the observed phenomena and those of other authors, before discussing the limits of our experimental techniques and methods to improve it. We draw the important conclusion that when optically trapping aerosols the system does not behave as a true `optical tweezers', varying between levitation and single beam gradient force trapping depending on particle and beam parameters.
Embedding-Based Sliding Mode Control for Linear Time Varying Systems  [PDF]
Mohammad Reza Zarrabi, Mohammad Hadi Farahi, Ali Jafar Koshkouei, Sohrab Effati, Keith Burnham
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.24063
Abstract: In this paper, a novel strategy using embedding process and sliding surface is proposed. In this method, a state trajectory starting from a given initial point reaches a definite point on a sliding surface in the minimum time, and then tends to the origin along the sliding surface (SS). In the first, a SS is designed, then using an appropriate measure, an embedding is constructed to solve a time optimal control problem such that the system trajectory reaches the SS in minimum time, after that a control is designed such that the system trajectory tends to the origin along the SS. It is well-known that the main disadvantage of the use of sliding mode controls (SMCs) is a phenomenon, the so-called chattering. The proposed SMC here is piecewise continuous and chattering free. Some numerical examples is presented to illustrate the effectiveness and reliability of the proposed method.
Discutindo a rela??o entre espa?o e aprendizagem na forma??o de profissionais de saúde

Interface - Comunica??o, Saúde, Educa??o , 2005, DOI: 10.1590/S1414-32832005000100009
Abstract: this article discusses the relation between space and learning, as a way of thinking of modifications or curricula innovations, based on demands from practice. it analyzes experiences with communities developed by nursing schools, schools of dentistry and medical schools. the epistemological / methodological proposal is based on the theories of complexity and of multiple references. analysis revealed significant learning experiences for the subjects and indicated that it is not enough to define new teaching sites; it is necessary to reflect upon practice, so that it may be a reference for questioning and transforming traditional forms of conceiving the curricula. furthermore, it indicated that rethinking the curricula signifies developing a new relationship with knowledge, which implies in changes in the relations between the university and the diverse forms of knowledge in existence and the recognition of the value of learning (re)constructed in experience. in conclusion, the article stresses that the university should institute mechanisms for listening to what various actors have to say about the practices it develops and invest in a solid cultural education that is critical with respect to the students.

Abstract: ndomized, double-blind, placebo-controlled, linear dose, crossover study to evaluate the efficacy and safety of a green coffee bean extract in overweight subjects Original Research (73483) Total Article Views Authors: Vinson JA, Burnham BR, Nagendran MV Published Date January 2012 Volume 2012:5 Pages 21 - 27 DOI: http://dx.doi.org/10.2147/DMSO.S27665 Received: 26 October 2011 Accepted: 17 November 2011 Published: 19 January 2012 Joe A Vinson1, Bryan R Burnham3, Mysore V Nagendran3 1Chemistry Department, 2Psychology Department, University of Scranton, Scranton, PA, USA; 3Health Sciences Clinic, Bangalore, India Background: Adult weight gain and obesity have become worldwide problems. Issues of cost and potential side effects of prescription weight loss drugs have led overweight and obese adults to try nutraceuticals that may aid weight loss. One promising nutraceutical is green coffee extract, which contains high concentrations of chlorogenic acids hat are known to have health benefits and to influence glucose and fat metabolism. A 22-week crossover study was conducted to examine the efficacy and safety of a commercial green coffee extract product GCA at reducing weight and body mass in 16 overweight adults. Methods: Subjects received high-dose GCA (1050 mg), low-dose GCA (700 mg), or placebo in separate six-week treatment periods followed by two-week washout periods to reduce any influence of preceding treatment. Treatments were counterbalanced between subjects. Primary measurements were body weight, body mass index, and percent body fat. Heart rate and blood pressure were also measured. Results: Significant reductions were observed in body weight (-8.04 ± 2.31 kg), body mass index (-2.92 ± 0.85 kg/m2), and percent body fat (-4.44% ± 2.00%), as well as a small decrease in heart rate (-2.56 ± 2.85 beats per minute), but with no significant changes to diet over the course of the study. Importantly, the decreases occurred when subjects were taking GCA. Body mass index for six subjects shifted from preobesity to the normal weight range (<25.00 kg/m2). Conclusion: The results are consistent with human and animal studies and a meta-analysis of the efficacy of green coffee extract in weight loss. The results suggest that GCA may be an effective nutraceutical in reducing weight in preobese adults, and may be an inexpensive means of preventing obesity in overweight adults.
The socialization of the scientific knowledge: a study in a discursive perspective
José Luis Michinel,Teresinha Fróes Burnham
Investiga??es em Ensino de Ciências , 2007,
Abstract: The goal of this work is the study of the socialization of the scientific knowledge produced by the scientific community that wishes to communicate it to “extended community”. We assume the socialization of knowledge as a condition of production of meanings, in a discursive perspective, which will allow us, more than the scientific information that wishes to communicate, to think about the actions involved in this (in)formation processes and the mediations and necessary means to the process in socialization perspective considered here, i.e., that information generated in the scientific community if transformed into personal knowledge of “social individuals” for the construction of necessary meanings to the citizenship formation. The Discourse Analyzes, in the French perspective, according to Pêcheux and Orlandi, functioned as a reference which allows us to face the problem and also characterize it in its theoretical and methodological approach.
