Abraham Lincoln Association Serials  

NSDL National Science Digital Library

Abraham Lincoln has been the subject of a variety of works, including plays, poems, songs, music videos, movies, and countless academic studies and dissertations. Between 1940 and 1952, the Abraham Lincoln Association published 52 issues of "The Abraham Lincoln Quarterly," which contained original articles regarding all facets of Lincoln's life and the world in which he lived. The University of Michigan digitized all of these volumes and they are now available on this site. There are hundreds of articles here, but visitors might do well to start with the very first one from the very first volume: "When War Came in 1861." Another fascinating article is the piece "Italy and Lincoln" from March 1944, which addresses the response to Lincoln's assassination from the Italian people.



Abraham Lincoln Papers  

NSDL National Science Digital Library

On February 12, the anniversary of Lincoln's birth, the Library of Congress (LOC) American Memory Project and the Lincoln Studies Center at Knox College made public the first release from The Complete Abraham Lincoln Papers at the Library of Congress, which totals approximately 20,000 documents. The complete collection is organized into three "General Correspondence" series. This release, which includes 2,200 annotated documents (about 6,500 images), comprises series one and contains correspondence dated from March 1829 through June 1864 that was originally gathered by Robert Todd Lincoln, Abraham Lincoln's son. Users can browse the collection chronologically or search by keyword. The site also includes two special presentations featuring original documents and images on the Emancipation Proclamation and Lincoln's assassination.


Abraham Lincoln's Gettysburg illness.  


When Abraham Lincoln delivered the Gettysburg Address, he was weak and dizzy; his face had a ghastly colour. That evening on the train to Washington, DC, he was febrile and weak, and suffered severe headaches. The symptoms continued; back pains developed. On the fourth day of the illness, a widespread scarlet rash appeared that soon became vesicular. By the tenth day, the lesions itched and peeled. The illness lasted three weeks. The final diagnosis, a touch of varioloid, was an old name for smallpox that was later used in the 20th century to denote mild smallpox in a partially immune individual. It was unclear whether Lincoln had been immunized against smallpox. Indeed, this review suggests that Lincoln had unmodified smallpox and that Lincoln's physicians tried to reassure the public that Lincoln was not seriously ill. Indeed, the successful conclusion of the Civil War and reunification of the country were dependent upon Lincoln's presidency. PMID:17551612

Collected Works of Abraham Lincoln  

NSDL National Science Digital Library

Amidst all of his other responsibilities as a lawyer, politician, and father, Abraham Lincoln found time to write. In fact, he wrote quite a bit, and it took scholars decades to assemble the majority of his various published (and unpublished) writings. After working on bringing together his writings, the Abraham Lincoln Association published "The Collected Works of Abraham Lincoln" in 1953. In total, there were eight volumes, and they included Lincoln's correspondence, speeches, and other writings. Recently, the University of Michigan's Digital Library Production Service digitized all eight volumes and placed them online here for the benefit of historians, rhetoricians, and those who are generally enamored of the 16th President. Visitors can perform simple searches, boolean searches, and proximity searches to their hearts' content. Also, they can look over other documents that were digitized for the collection, including Paul M. Angle's "Here I Have Lived: A History of Lincoln's Springfield".

NSDL National Science Digital Library

Composed of North American volunteers, the Abraham Lincoln Brigade was one of several international brigades that fought on the side of the Republicans against Franco's fascist Nationalists in the Spanish Civil War (1936-9). The ALBA was founded in 1975 by the Veterans of the Abraham Lincoln Brigade (VALB) to preserve the history of the Brigade's actions in Spain and the post-war activities of its veterans in America. Part of ALBA's mission includes supervising the comprehensive archive of materials related to the North American involvement in the Spanish Civil War at Brandeis University. At the ALBA site, users will find exhibits of posters and photos brought back by volunteers; contact information for researchers interested in using the archive; a high school curriculum entitled "Between the World Wars," downloadable in .pdf format; a brief history of the VALB and recent issues of its journal, The Volunteer (in .pdf format); a discussion list; and related links.


Abraham Lincoln Historical Digitization Project  

NSDL National Science Digital Library

The ambitious goal of the Abraham Lincoln Historical Digitization Project is to bring together digital versions of documents, images, and even music related to Abraham Lincoln's life in Illinois from institutions throughout that state. Users will be able to access materials via browsing chronological and thematic sections or searching database sets. Currently a pilot database of 70 campaign songs from the 1860 Lincoln-Douglas presidential race is available at the site. In keeping with the project goals, the site presents the campaign songs in three ways: digital images of sheet music pages, searchable text transcriptions, and digital audio recordings of selected songs. It is possible to search the collection for songs pertaining to specific topics or including specific words, browse by title, or select from a digital table of contents. Lincoln Digitization Project staff hope for users to "gain new insights into the campaign of 1860 and the antebellum period's fascinating political culture."

Estimation of Abraham solvation equation coefficients for hydrogen bond formation from Abraham solvation parameters for solute acidity and basicity.  


Abraham solvation equations find widespread use in environmental chemistry and pharmaco-chemistry. The coefficients in these equations, which are solvent (system) descriptors, are usually determined by fitting experimental data. To simplify the determination of these coefficients in Abraham solvation equations, this study derives equations, based on Abraham solvation parameters for hydrogen acidity and basicity of the solvents involved, to estimate the value of the coefficients for hydrogen bond formation. These equations were applied to calculate Abraham solvation parameters for hydrogen acidity and basicity for polyoxymethylene, polyacrylate, sodium dodecylsulfate, some ionic liquids, alkanoyl phosphatidyl cholines, and lipids for which fitted values for Abraham coefficients for hydrogen bond formation were available.

Spherical gravitational wave detectors: MiniGRAIL and Mario Schenberg  

NASA Astrophysics Data System (ADS)

Spherical gravitational wave detectors allow the analysis of multiple independent channels and, therefore, are able to determine gravitational wave directions and polarizations. There are two spherical detectors being developed now: MiniGRAIL (Netherlands) and Mario Schenberg (Brazil). Both share the same principle of detection and main features. They have done commissioning runs and shown progress in their development. We have presented here the status of Mario Schenberg. Its transducers have been redesigned for sensitivity improvements. While an offline analysis was already developed for MiniGRAIL, we have investigated a low latency data analysis technique for Mario Schenberg. Both analysis are based on directional detection.

Abraham Colles and his contributions to anatomy.  


Abraham Colles is known among the medical community for his detailed description of Colles' fracture, one of the most common occurring skeletal injuries. It is remarkable that something as seemingly simple as the diagnosis of Colles' fracture had not been established until nearly 200 years ago. While that may have been his most well known accomplishment, Colles made several other contributions to medicine across multiple fields of practice. In the field of anatomy, he is also credited for his discovery and description of Colles' fascia and Colles' ligament. Less commonly known, however, are his clinical observations and offered treatment regimens for syphilis, as well as his achievement in performing the first surgery for axillary artery aneurysm. The current paper will review the life and contributions of this early surgeon and anatomist. PMID:23959912

Hogenberg: Franz and Abraham Hogenberg Engravings  

NSDL National Science Digital Library

The Princeton University Library was the recipient of 1986 graduate Bruce Willsie's collection of 155 engravings, from the GeschichtsblÃÂätter (History Sheets) published between 1570 and 1610. The engravings, by Franz and Abraham Hogenberg depict the Eighty Years War of 1568-1648, and have been made accessible online by the Princeton University Library Digital Collections. Visitors should click on the "Collection Images" link in the middle of the homepage to access the detailed images. The images are shown one by one as the default, but can also be viewed as thumbnails by clicking on the button with the grid on it, below the written menu. Although the titles of each engraving are in Dutch, the descriptions are in English. Each engraving of a scene from the War depicts a distinct event, and offers much for visitors to peruse with abundant detail. Visitors should not miss zooming in on any of the images to see them in detail. Users can use the cross of double-headed arrows to interact with the image as well. Item 147, "Arnheim/Knodsenbrug/Nijmwegen" is a great example of the engraving skills involved in the depiction of the soldiers' uniforms and equipment.


Abraham Lincoln and the insanity plea.  


A confederate civilian physician shot and killed a white Union officer who was drilling Negro troops in Norfolk, Virginia. With no question as to guilt, President Abraham Lincoln decided to have a medical expert conduct a professional sanity/insanity examination. Documentation indicates that legal and political factors may have influenced Lincoln's decision. As a lawyer, Lincoln prosecuted a case where the insanity plea was used as a defense. Two influential Cabinet members, William H. Seward and Edwin M. Stanton, also had legal experience involving the insanity plea. Politically, Lincoln faced serious issues such as the draft riots, the military necessity to recruit slaves into the army, the impact of Union Negro soldiers upon the border states, the morale and discipline of the army and the upcoming presidential election. Upon Seward's recommendation, Lincoln chose a physician who had a reputation for finding the accused sane and who did so in this case. As the southern physician was hanged, Lincoln's means achieved the desired legal and political ends. PMID:8089270

Abraham Lincoln and the global economy.  


Abraham Lincoln would have well understood the challenges facing many modern emerging nations. In Lincoln's America, as in many developing nations today, sweeping economic change threatened older industries, traditional ways of living, and social and national cohesion by exposing economies and societies to new and powerful competitive forces. Yet even in the midst of the brutal and expensive American Civil war--and in part because of it--Lincoln and the Republican Congress enacted bold legislation that helped create a huge national market, a strong and unified economy governed by national institutions, and a rising middle class of businessmen and property owners. Figuring out how to maximize the benefits of globalization while minimizing its disruptions is a formidable challenge for policy makers. How do you expand opportunities for the talented and the lucky while making sure the rest of society doesn't fall behind? It may be helpful to look at the principles that informed the policies that Lincoln and the Republican Congress instituted after they came to power in 1861: Facilitate the upward mobility of low- and middle-income groups to give them a significant stake in the country. Emphasize the good of the national economy over regional interests. Affirm the need for sound government institutions to temper the dynamics of the free enterprise system. Tailor policies to the national situation. Realize that a period of turmoil may present a unique opportunity for reform. These principles drove the reforms that helped Americans cope with and benefit from rapid technological advances and the fast integration of the American economy in the nineteenth century. They may be instructive to today's policy makers who are struggling to help their own citizens integrate into the fast-changing global economy of the twenty-first century. PMID:12884668

On Mario Bunge's Definition of System and System Boundary  

ERIC Educational Resources Information Center

In this short paper we discuss Mario Bunge's definition of system boundary. It is quickly discovered that Bunge's definition of system and system boundary are both deficient. We thus propose new definitions, which (hopefully) improve the situation. Our definition of system boundary works off the same intuition behind Bunge's.

Possibility of measuring the Abraham force using whispering gallery modes  

SciTech Connect

Critical experimental tests of the time-dependent Abraham force in phenomenological electrodynamics are scarce. In this paper, we analyze the possibility of making use of intensity-modulated whispering gallery modes in a microresonator for this purpose. Systems of this kind appear attractive, as the strong concentration of electromagnetic fields near the rim of the resonator serves to enhance the Abraham torque exerted by the field. We analyze mainly spherical resonators, although as an introductory step we consider also the cylinder geometry. The orders of magnitude of the Abraham torques are estimated by inserting reasonable and common values for the various input parameters. As expected, the predicted torques turn out to be very small, although probably not beyond reach experimentally. Our main idea is essentially a generalization of the method used by G. B. Walker et al.[Can. J. Phys. 53, 2577 (1975)] for low-frequency fields, to the optical case.

Abraham Lincoln, psychotherapist to the nation: the use of metaphors.  


Metaphors are widely utilized in psychotherapy to effect change in patients. Psychotherapeutic metaphors, in their various versions, may offer new choices and ways of viewing oneself to the patient which are more palatable than straight discussions or sterile insights. By addressing resistances indirectly, metaphors can be an effective tool for the therapist to use, regardless of theoretical orientation. Abraham Lincoln, a master of metaphor, utilized this tool effectively in dealing with crises and the ultimate fragmentation, disunion of the national identity. The author argues that Lincoln was able to address complex issues (such as slavery, liberty, nationhood, union, and conduct of the war) with metaphors, much as a skilled psychotherapist addresses complex issues within his or her purview. Abraham Lincoln effectively disarmed his critics, established a means of communication with the people, and sought to make his points in an understandable nonconfrontational fashion. These are skills highly valued by psychotherapists. One might say that Abraham Lincoln conducted psychotherapy on a national scale. Without formal training, he was ultimately able to create a new and more stable sense of national self using a metaphorical approach. PMID:9139547

Mario Bunge, Systematic Philosophy and Science Education: An Introduction  

NASA Astrophysics Data System (ADS)

Mario Bunge was born in Argentina in 1919 and is now in his mid-90s. He studied atomic physics and quantum mechanics with Guido Beck (1903-1988), an Austrian refugee and student of Heisenberg. Additionally he studied modern philosophy in an environment that was a philosophical backwater becoming the first South American philosopher of science to be trained in science. His publications in physics, philosophy, psychology, sociology and the foundations of biology, are staggering in number, and include a massive 8-volume Treatise on Philosophy. The unifying thread of his scholarship is the constant and vigorous advancement of the Enlightenment Project, and criticism of cultural and academic movements that deny or devalue the core planks of the project: namely its naturalism, the search for truth, the universality of science, the value of rationality, and respect for individuals. At a time when specialisation is widely decried, and its deleterious effects on science, philosophy of science, educational research and science teaching are recognised, and at a time when `grand narratives' are thought both undesirable and impossible—it is salutary to appraise the fruits of one person's pursuit of the `Big' scientific and philosophical picture or grand narrative. In doing so this special issue brings together philosophers, physicists, biologists, sociologists, logicians, cognitive scientists, economists and mathematicians to examine facets of Mario Bunge's systematic philosophy and to appraise its contribution to important issues in current philosophy and, by implication, education.

Unilateral coronal craniosynostosis in Abraham Lincoln and his family.  


Premature closure of one coronal skull suture produces a characteristic arching or relative elevation of the superior orbital rim on the involved side. This sign is associated with facial asymmetry, and both signs are usually the most conspicuous features in patients with mild unilateral coronal craniosynostosis. Photographs suggest that at least 9 individuals over 5 generations of the Abraham Lincoln family had premature closure of 1 coronal suture. In 8 males, there was involvement of the left side; in 1 female, there was involvement of the right side. PMID:20856045

Abraham Lincoln did not have type 5 spinocerebellar ataxia.  


An autosomal dominant genetic disorder, type 5 spinocerebellar ataxia (SCA5), occurs in multiple descendants of one paternal uncle and one paternal aunt of President Abraham Lincoln. It has been suggested that Lincoln himself had the disease and that his DNA should be tested for an SCA5-conferring gene. Herein, I review the pertinent phenotypes of Lincoln, his father, and his paternal grandmother, and conclude that 1) Lincoln's father did not have SCA5, and, therefore, that Lincoln was not at special risk of the disease; 2) Lincoln had neither subclinical nor visible manifestations of SCA5; 3) little evidence suggests SCA5 is a "Lincolnian" disorder; and 4) without additional evidence, Lincoln's DNA should not be tested for SCA5.

Motivating Calculus-Based Kinematics Instruction with Super Mario Bros  

NASA Astrophysics Data System (ADS)

High-quality physics instruction is contextualized, motivates students to learn, and represents the discipline as a way of investigating the world rather than as a collection of facts and equations.1 Inquiry-oriented pedagogy, such as problem-based instruction, holds great promise for both teaching physics content and representing the process of doing real science.2 A challenge for physics teachers is to find instructional contexts that are meaningful, accessible, and motivating for students. Today's students are spending a growing fraction of their lives interacting with virtual environments, and these environments--physically realistic or not--can provide valuable contexts for physics explorations3-5 and lead to thoughtful discussions about decisions that programmers make when designing virtual environments. In this article, I describe a problem-based approach to calculus-based kinematics instruction that contextualizes students' learning within the Super Mario Bros. video game--a game that is more than 20 years old, but still remarkably popular with today's high school and college students.

With Malice Toward None: The Abraham Lincoln Bicentennial Exhibition  

NSDL National Science Digital Library

Abraham Lincoln's accomplishments have been reaffirmed in the nation's conscience over the past two years in part due to President Obama's great respect for him. But President Obama is not the only one who brings attention to the already revered Lincoln. The Library of Congress is honoring Lincoln's 200th birthday with online exhibit and physical exhibits in Washington, D.C., along with several other locales throughout the year. One of the more eye-catching features of the online exhibit is called "Lincoln Vignettes", on the far right side of the page. Here, drawings, photos, or sculptures of Lincoln represent different time periods of his life. Clicking on each image will take visitors to several items representative of that time period in his life, including photos and documents written by him or about him. Especially noticeable is the way that Lincoln's appearance changed not only as he grew older, but also as he grew more challenged by the strife and war in the country. The photo "At War's End" is a striking example. The tab "Exhibition Items", near the top of the homepage requires downloading Microsoft's Silverlight software to view, which takes just a minute or two, and it allows the feature to work like a sophisticated album. The images can be enlarged or viewed in full screen, and each image has an informative description. The images can be viewed alphabetically or by theme.

Karl Abraham's revolution of 1916: from sensual sucking to the oral-aggressive wish of destruction.  


The author argues that "The First Pregenital Stage of the Libido" (Abraham 1916-1917) expounds a new conception of orality, i.e., of purposeful oral aggression directed against an object during the first stage of psychic development. This conception is shown to be contrary to Freud's view of orality as elaborated in Three Essays on the Theory of Sexuality (1905), as well as in other writings of late 1914 and 1915. Abraham's conception ignores fundamental dimensions of Freud's thinking during these years, namely, the difference between autoerotism/narcissism and object love, on the one hand, and also between the leading role of sexuality and the secondary role of aggression, on the other. Thus, Abraham's thinking represents a basic theoretical change that had far-reaching consequences for psychoanalytic practice. PMID:22423435

Non-polynomial extensions of solvable potentials à la Abraham-Moses  

SciTech Connect

Abraham-Moses transformations, besides Darboux transformations, are well-known procedures to generate extensions of solvable potentials in one-dimensional quantum mechanics. Here we present the explicit forms of infinitely many seed solutions for adding eigenstates at arbitrary real energy through the Abraham-Moses transformations for typical solvable potentials, e.g., the radial oscillator, the Darboux-Pöschl-Teller, and some others. These seed solutions are simple generalisations of the virtual state wavefunctions, which are obtained from the eigenfunctions by discrete symmetries of the potentials. The virtual state wavefunctions have been an essential ingredient for constructing multi-indexed Laguerre and Jacobi polynomials through multiple Darboux-Crum transformations. In contrast to the Darboux transformations, the virtual state wavefunctions generate non-polynomial extensions of solvable potentials through the Abraham-Moses transformations.

For instance, he was one of the first investigators to recognize that fixed thallium defects were often not just scar but could be reversed by coronary revascularization. This led to an extensive revision of accepted traditional concepts on the meaning of image patterns. Mario's work on risk stratification by myocardial perfusion and function imaging after acute myocardial infarction was equally pioneering. He also laid out the basic principles for the safe use of adenosine for pharmacologic stress testing. Adenosine is now the preferred procedure all over the world in millions of patients. Dr Verani was a founding member and past president (1996-1997) of the American Society of Nuclear Cardiology (ASNC). The day before he died, he received the ASNC Distinguished Service Award. Personally, I will remember Mario as a very dear friend. We spent many hours together at meetings and gatherings all over the world. I still miss his outgoing personality, his warmth, his humor, and his enthusiasm. Above all, I enjoyed his comfortable friendship. That this friendship extended itself naturally to our wives, Regina and Marjan, made it all the more special. One of the best times we had was during a cardiology meeting in Recife, in the country of his birth, Brazil. I was greatly amused and, at the same time, impressed by the admiration and respect bestowed on him by his fellow Brazilians. One evening, we were going some place in the street on foot. We could not walk down the street without Mario being stopped by one or another Brazilian cardiologist who wanted to speak and consult with him. He was clearly greatly admired and appreciated in his country. I jokingly called him "King of Recife," and the king was holding audience. We arrived rather late where we were going... . I will always cherish the memories of our times together. I am grateful that I could visit Mario at his sickbed on the day before he passed away. He was so fragile and, at the same time, so courageous. I felt sad that there was so much that we could have discussed that we did not. Life seems sometimes full of missed opportunities... .

The Solar Tower at Monte Mario: a New Didactic Laboratory for Astronomy  

NASA Astrophysics Data System (ADS)

The year 2009 witnessed the restoration of the Solar Tower of Astronomical Observatory of Rome, in the INAF main office of Villa Mellini, Monte Mario. This structure underwent a patient restructuring of optics, mechanics and control equipment. Moreover, some areas have been converted into welcome centre for the visitors, so as to transform a scientific instrument - which was active up to a few years ago - into a didactic structure, mainly suitable for school groups. The Solar Tower of Monte Mario, which has been open to the public since January 2010, allows visitors to directly observe the Sun, as well as the spectrum of its light. The Tower therefore becomes an effective didactic instrument in order to teach and talk about a wide range of scientific topics - from Solar Physics to Sun-Earth interactions, to Stellar Evolution. Here we describe the work done by the DivA group of INAF-OAR for putting back into service the Solar Tower, from the technical and didactic viewpoints. We shall also take stock of the activities organized in the first few months of activity.

Axiomatic Geometrical Optics, Abraham-Minkowski Controversy, and Photon Properties Derived Classically  

SciTech Connect

By restating geometrical optics within the eld-theoretical approach, the classical concept of a photon in arbitrary dispersive medium is introduced, and photon properties are calculated unambiguously. In particular, the canonical and kinetic momenta carried by a photon, as well as the two corresponding energy-momentum tensors of a wave, are derived straightforwardly from rst principles of Lagrangian mechanics. The Abraham-Minkowski controversy pertaining to the de nitions of these quantities is thereby resolved for linear waves of arbitrary nature, and corrections to the traditional formulas for the photon kinetic quantities are found. An application of axiomatic geometrical optics to electromagnetic waves is also presented as an example.

The role of Abraham Lincoln in securing a charter for a homeopathic medical college.  


In 1854, Abraham Lincoln was retained to prepare a state legislative proposal to charter a homeopathic medical college in Chicago. This was a complex task in view of the deep-seated animosity between allopathic or orthodox medical practitioners and irregular healers. Homeopathy was regarded as a cult by the nascent American Medical Association. In addition, the poor reputation of medical education in the United States in general, further complicated the project. Lincoln and influential individuals in Illinois lobbied legislators and succeeded in securing the charter. Subsequently, the Hahnemann Homeopathic Medical College accepted its first class in 1860 and with its successors remained in existence for almost sixty-five years. PMID:12238734

A rare depiction of Abraham Lincoln turns up in New Hampshire  

NSDL National Science Digital Library

Long-Lost 1913 Lincoln Film to Premiere at the Putnam Film Preservation Foundation Bioscope Archive: Abraham Lincoln Movies Lincoln is making his way back to the silver screen, albeit in a somewhat unexpected fashion. Back in 2006, carpenter Peter Massie was cleaning out an old barn in Nelson, New Hampshire when he came across an old projector and seven reels of film. As it turns out, one of the films on these reels was "When Lincoln Paid", a silent film from 1913 directed by Francis Ford. Ford plays Lincoln in the 30-minute film, and his younger brother, John Ford, would go on to acclaim as the director of many celebrated Westerns. The find was quite unusual, as over 90 percent of the films made before 1927 no longer exist. After finding the films, Massie took them to Keene State film professor Lawrence Benaquist, who was able to identify all of the films after some investigative work. The folks at the George Eastman House in Rochester, New York and the National Film Preservation Foundation assisted in the film's restoration, and it is set to receive its first formal showing at the Redfern Arts Center at Keene State College on April 20.The first link will take users to a news article from this Tuesday's New Hampshire Union Leader about this rather unique find.

Interview: Dr Mario Raviglione, Director of the Stop TB Department World Health Organization  

PubMed Central

Tuberculosis (TB) is a very global disease; there are over 9 million new incidences of TB every year with the vast majority of cases emerging in the developing world. As one of three major diseases associated with poverty it affects the areas where poverty is most prevalent, notably Asia and Africa. While the incidence rate has been slowly declining in the developed world it continues to pose a major health threat to even the most developed nations. To demonstrate the global, and persistent, nature of TB we asked Dr Mario Raviglione, Director of the World Health Organization’s Stop TB Department to provide an analysis on the current TB situation in the United Kingdom and comment on what measures should be taken to alleviate the issue of TB in one of the world’s richest countries.

The Illinois Harvest Digital Collection presents a wide variety of cultural and historical materials related to the state of Illinois. The project began in 2006 and has resulted in many thousands of works being added to its rolls. This rather compelling corner of the collection presents over 1,400 publications related to Abraham Lincoln, with a discrete focus on biographies of the man, slavery, and the American Civil War. One particularly noteworthy title is the 1945 work, "Intimate Memories of Lincoln." This piece, a compilation of anecdotes from people who knew Lincoln well, is quite an intriguing read. Visitors, particularly those who love American history and related subjects, will find they can easily wander around this collection for hours.


Abraham Lincoln's blue pills. Did our 16th president suffer from mercury poisoning?  


It is well known that Abraham Lincoln took a medicine called "blue mass" or "blue pill," commonly prescribed in the 19th century. What is now hardly known is that the main ingredient of blue mass was finely dispersed elemental mercury. As his friends understood, mercury was often prescribed for melancholy or "hypochondriasis," a condition Lincoln famously endured. Mercury in the form of the blue pill is a potential neurotoxin, which we have demonstrated by recreating and testing the recipe. We present the testimony of many of Lincoln's contemporaries to suggest that Lincoln suffered the neurobehavioural consequences of mercury intoxication but, perhaps crucial to history, before the main years of his presidency; he was astute enough to recognize the effects and stop the medication soon after his inauguration.

Abraham Flexner first toured the Yale University School of Medicine in preparation for his report of 1910, but it was just the beginning of his relationship with the school. While his review of Yale in his report was generally favorable, he mentioned several shortfalls that needed to be improved to make the school acceptable. Throughout the next twenty-five years, Flexner worked with Deans George Blumer and Milton C. Winternitz to improve the school’s finances, infrastructure, and quality of education through his work with the Carnegie Foundation and General Education Board. Flexner has been given great accolades for his work on medical education for the country, but little mention is made of him at Yale, even though he was one of the most influential figures in the development of Yale in the last century.

On acoplamento mecânico entre a antena e o transdutor no detector de ondas gravitacionais Mario Schenberg  

NASA Astrophysics Data System (ADS)

O detector de ondas gravitacionais MARIO SCHENBERG consistirá de uma massa esférica de cobre-alumínio de 1150kg resfriada a 4K, sobre a qual serão instalados 6 transdutores de nióbio. Com estes trandutores pretende-se converter um possível sinal de onda gravitacional detectado em sinal elétrico, para tanto é necessário que o acoplamento mecânico entre os transdutores e a massa ressonante seja o maior possível. Isto significa que o transdutor deve ser ressonante na mesma freqüência que a antena (aproximadamente 3200Hz). Neste trabalho foi desenvolvida uma geometria para a estrutura mecânica do trandutor. Isto foi feito criando-se modelos em elementos finitos usando-se o "software" MSC/Nastran. Estes modelos criados foram analisados estaticamente (cálculo de tensões) e dinamicamente (cálculo das freqüências de ressonâncias e seus respectivos modos normais) de maneira a se obter o primeiro modo normal do transdutor em 3200Hz. A partir destes cálculos escolheu-se a melhor geometria para o transdutor. Os próximos passos do trabalho serão: usinar este transdutor em uma barra de nióbio e testá-lo à temperatura ambiente e à baixa temperatura. Após isto, pretende-se testá-lo na própria antena resfriada.

Resposta do detector de ondas gravitacionais Mario Schenberg ao "ringdown" de buraco negros  

NASA Astrophysics Data System (ADS)

Acredita-se que quando duas estrelas de nêutrons coalescem, elas, eventualmente, formam um buraco negro com massa igual a soma das massas dos objetos originais. Durante a formação do buraco negro, o espaço-tempo em torno do sistema sofre perturbações que se propagam na forma de radiação gravitacional. A forma de onda associada a radiação gravitacional, durante este estágio, aproxima-se a uma senóide exponencialmente amortecida. Este tipo de sinal é conhecido como "ringdown", e seu comportamento e parametrização são muito bem conhecidos. Neste trabalho, simulamos computacionalmente sinais provenientes do "ringdown" de buracos negros, com a finalidade de testar o desempenho do detector de ondas gravitacionais Mario Schenberg em observá-los, quando entrar em funcionamento. Este primeiro teste teórico ajudou-nos a criar estratégias de detecção de sinais imersos no ruído instrumental. Calculamos a relação sinal-ruído como uma função da frequência, bem como sua integral dentro da faixa de sensibilidade do detector. Os resultados obtidos mostraram que o detector Schenberg terá sensibilidade suficiente para detectar este tipo de sinal, proveniente de fontes astrofísicas localizadas dentro de um raio de ~100kpc.

Taxas de eventos para as fontes astrofísicas do detector Mario Schenberg  

NASA Astrophysics Data System (ADS)

O detector de ondas gravitacionais Mario Schenberg será sensível a sinais que cheguem à Terra com amplitude h~10-21 e dentro da faixa em frequências que varia de 3,0 a 3,4 kHz. As principais fontes astrofísicas em condições de gerar um sinal detectável pela antena Schenberg são: colapsos estelares que produzam eventos do tipo supernova; instabilidades hidrodinâmicas em estrelas de nêutrons; excitação dos modos fluído (modos f) de estrelas de nêutrons; excitação dos primeiros modos quadrupolares de buracos negros com massa ~ 3,8 M¤; coalescências de estrelas de nêutrons e buracos negros em sistemas binários e, ainda, espiralações de mini-buracos negros. Neste trabalho nós determinamos as taxas de eventos para o Schenberg associadas a dois tipos de fontes: através da de-excitação dos modos f de estrelas de nêutrons e através da coalescência de mini-buracos negros de 0,5 M¤ (que atualmente têm sido colocados como possíveis candidatos a objetos massivos do halo Galáctico). Nós mostramos que esses tipos de fontes poderão produzir sinais em ondas gravitacionais com uma taxa em torno de um evento por ano dentro da banda do Schenberg.

The cosmic ray veto system of the Mario Schenberg gravitational wave detector  

NASA Astrophysics Data System (ADS)

The Mario Schenberg gravitational wave antenna is a spherical cryogenic resonant mass detector located at IFUSP, São Paulo. It is well known that cosmic rays interact with cryogenic resonant mass detectors generating acoustic signals. Depending on the shower energy, they could provide a substantial background noise which should be vetoed to reduce the false alarm rate. For this purpose, in December 2011, we have installed a cosmic ray veto system which is, since then, acquiring data. The cosmic ray veto system is composed of three particle detectors containing each one a scintillator, a photomultiplier and a tension divider. As the shower number of particles is used to define a threshold for the veto, it is important that the cosmic ray veto provides a linear response to high-energy cosmic ray events. The veto setup response was optimized and allows measurements up to 23,000 equivalent muon charge particles per square meter. We present here the experimental setup, its calibration and performance. Finally, to confirm the linearity of the data acquisition we show the measured particle multiplicity.

Low-latency data analysis for the spherical detector Mario Schenberg  

NASA Astrophysics Data System (ADS)

The confrontation of gravitational waves (GWs) with their electromagnetic (EM) counterparts will be rich with information about astrophysical events. Initially, this confrontation will corroborate GW detections; afterwards, when GW detections become more recurrent, it will allow astrophysics to combine information from different channels (GW, EM and also neutrinos). A low-latency data analysis which provides the direction of an incoming GW candidate is required to confront it with fast follow-up EM observations. Until now, no low-latency data analysis has been developed for spherical detectors. One spherical detector alone is capable of determining both the GW direction and polarization. By using this capability, we have developed a low-latency data analysis pipeline for the Mario Schenberg detector. This pipeline is able to retrieve the direction of GW triggers with an average angular resolution from ?s ? 8° at SNR ? 12 to ?s ? 1° at SNR ? 80, in a timespan of a 4 s for 32 s of data being analyzed. We apply a veto which reduces fake events up to 90% when maintaining the GW efficiency above 90% for high SNRs. We provide here a description of the method and its efficiency: resolution on the direction, false alarm rate and computational time.

Resolution of the Abraham-Minkowski debate: Implications for the electromagnetic wave theory of light in matter  

NASA Astrophysics Data System (ADS)

A century has now passed since the origins of the Abraham-Minkowski controversy pertaining to the correct form of optical momentum in media. Experiment and theory have been applied at both the classical and quantum levels in attempt to resolve the debate. The result of these efforts is the identification of Abraham's kinetic momentum as being responsible for the overall center of mass translations of a medium and Minkowski's canonical or wave momentum as being responsible for translations within or with respect to a medium. In spite of the recent theoretical developments, much confusion still exists regarding the appropriate theory required to predict experimental outcomes and to develop new applications. In this paper, the resolution of the longstanding Abraham-Minkowski controversy is reviewed. The resolution is presented using classical electromagnetic theory and logical interpretation of experiments disseminated over the previous century. Emphasis is placed on applied physics applications: modeling optical manipulation of cells and particles. Although the basic interpretation of optical momentum has been resolved, there is still some uncertainly regarding the complete form of the momentum continuity equation describing electromagnetics. Thus, while a complete picture of electrodynamics has still yet to be fully interpreted, this correspondence should help clarify the state-of-the-art view.

Abraham Lincoln and Harry Potter: children's differentiation between historical and fantasy characters.  


Based on the testimony of others, children learn about a variety of figures that they never meet. We ask when and how they are able to differentiate between the historical figures that they learn about (e.g., Abraham Lincoln) and fantasy characters (e.g., Harry Potter). Experiment 1 showed that both younger (3- and 4-year-olds) and older children (5-, 6-, and 7-year-olds) understand the status of familiar figures, correctly judging historical figures to be real and fictional figures to be pretend. However, when presented with information about novel figures embedded in either a realistic narrative or a narrative with obvious fantasy elements, only older children used the narrative to make an appropriate assessment of the status of the protagonist. In Experiment 2, 3-, and 4-year-olds were prompted to judge whether the story events were really possible or not. Those who did so accurately were able to deploy that judgment to correctly assess the status of the protagonist. PMID:19766203

Abraham Lincoln loses a medical malpractice case, debates Stephen A. Douglas, and secures two murder acquittals.  


An improperly healed fracture was the most common reason for the medical malpractice crisis between the 1830s and 1860s in the United States. As a practicing lawyer in Illinois, Abraham Lincoln defended physicians in medical malpractice law suits. One of these was Dr. Powers Ritchey, who was sued for malpractice in 1855. Lincoln agreed to represent Dr. Ritchey in 1858 as the case was appealed to the supreme court of Illinois. In the interim, Lincoln defended two indicted murderers and won acquittals for both. Between the two murder trials, Lincoln debated Stephen A. Douglas while running for U.S. Senator from Illinois. Lincoln believed that Ritchey's case was poorly represented in the lower court. Ritchey's prior attorneys did not file a bill of exceptions to the testimony of the plaintiff's expert medical witnesses. Lincoln attempted to rebut the allegation of a lack of reasonable medical care and diligence by Ritchey, and he sought to secure a new trial for his client. In its decision, the supreme court of Illinois did not find any error and affirmed the lower court's judgment. PMID:14768936

Projeto do sistema anti-ressonante da fiação dos transdutores para o detector Mario Schenberg  

NASA Astrophysics Data System (ADS)

O detector de ondas gravitacionais Mario Schenberg está sendo projetado e construído pelo grupo Gráviton. Sua construção está ocorrendo no Laboratório de Estado Sólido e Baixas Temperaturas (LESBT) da Universidade de São Paulo, na cidade de São Paulo. Esse detector possui uma massa ressonante esférica de cobre-alumínio, com 65 cm de diâmetro, pesando aproximadamente 1150 Kg, suspensa por um sistema de isolamento vibracional, que se encontra em fase de testes preliminares. A real eficácia desse sistema, entretanto, só poderá ser comprovada quando o detector estiver aparelhado com, pelo menos, um transdutor eletromecânico de altíssima sensibilidade acoplado à massa ressonante. Neste momento, não só este sistema de isolamento vibracional será posto em teste, como o do projeto da fiação que transporta os sinais de microondas até os transdutores e destes para a pré-amplificação. Apesar dessa fiação ter sido projetada para não apresentar nenhum contato com a superfície esférica da antena, de maneira a não haver nenhuma transmissão de ruído vibracional do laboratório para esta, deve-se minimizar o ruído microfônico produzido nessa fiação por oscilações mecânicas, uma vez que ela não utiliza nenhum sistema de isolamento vibracional. Com o intuito de resolver este problema, projetamos uma estrutura, formada por pequenos cilindros conectados por barras, a qual não terá nenhuma ressonância mecânica na faixa de freqüências de interesse para detecção (3000 - 3400 Hz). Desta forma, as vibrações nessa faixa não serão amplificadas. O projeto foi feito usando iterativamente, de maneira a otimizar os resultados obtidos, o programa de elementos finitos Msc/Nastran. Através de simulações feitas neste programa, determinamos os parâmetros geométricos ideais a serem utilizados, os quais proporcionam a maior região espectral de interesse livre de ressonâncias.

Reforming medical education in ethics and humanities by finding common ground with Abraham Flexner.  


Abraham Flexner was commissioned by the Carnegie Foundation for the Advancement of Teaching to conduct the 1910 survey of all U.S. and Canadian medical schools because medical education was perceived to lack rigor and strong learning environments. Existing proprietary schools were shown to have inadequate student scholarship and substandard faculty and teaching venues. Flexner's efforts and those of the American Medical Association resulted in scores of inadequate medical schools being closed and the curricula of the survivors being radically changed. Flexner presumed that medical students would already be schooled in the humanities in college. He viewed the humanities as essential to physician development but did not explicitly incorporate this position into his 1910 report, although he emphasized this point in later writings. Medical ethics and humanities education since 1970 has sought integration with the sciences in medical school. Most programs, however, are not well integrated with the scientific/clinical curriculum, comprehensive across four years of training, or cohesive with nationally formulated goals and objectives. The authors propose a reformation of medical humanities teaching in medical schools inspired by Flexner's writings on premedical education in the context of contemporary educational requirements. College and university education in the humanities is committed to a broad education, consistent with long-standing tenets of liberal arts education. As a consequence, premedical students do not study clinically oriented science or humanities. The medical school curriculum already provides teaching of clinically relevant sciences. The proposed four-year curriculum should likewise provide clinically relevant humanities teaching to train medical students and residents comprehensively in humane, professional patient care.

Psycho-neural Identity as the Basis for Empirical Research and Theorization in Psychology: An Interview with Mario A. Bunge  

NASA Astrophysics Data System (ADS)

Mario Bunge is one of the most prolific philosophers of our time. Over the past sixty years he has written extensively about semantics, ontology, epistemology, philosophy of science and ethics. Bunge has been interested in the philosophical and methodological implications of modern psychology and more specifically in the philosophies of the relation between the neural and psychological realms. According to Bunge, functionalism, the philosophical stand of current psychology, has limited explanatory power in that neural processes are not explicitly acknowledged as components or factors of psychological phenomena. In Matter and Mind (2010), Bunge has elaborated in great detail the philosophies of the mind-brain dilemma and the basis of the psychoneural identity hypothesis, which suggests that all psychological processes can be analysed in terms of neural and physical phenomena. This article is the result of a long interview with Dr. Bunge on psychoneural identity and brain-behaviour relations.

Highlighting Kathleen Green and Mario Delmar, Guest Editors of Special Issue (part 2): Junctional Targets of Skin and Heart Disease.  


Abstract Cell Communication and Adhesion has been fortunate to enlist two pioneers of epidermal and cardiac cell junctions, Kathleen Green and Mario Delmar, as Guest Editors of a two part series on junctional targets of skin and heart disease. Part 2 of this series begins with an overview from Dipal Patel and Kathy Green comparing epidermal desmosomes to cardiac area composita junctions, and surveying the pathogenic mechanisms resulting from mutations in their components in heart disease. This is followed by a review from David Kelsell on the role of desmosomal mutation in inherited syndromes involving skin fragility. Agnieszka Kobeliak discusses how structural deficits in the epidermal barrier intersect with the NFkB signaling pathway to induce inflammatory diseases such as psoriasis and atopic dermatitis. Farah Sheikh reviews the specialized junctional components in cardiomyocytes of the cardiac conduction system and Robert Gourdie discusses how molecular complexes between sodium channels and gap junction proteins within the perijunctional microdomains within the intercalated disc facilitate conduction. Glenn Radice evaluates the role of N-cadherin in heart. Andre Kleber and Chris Chen explore new approaches to study junctional mechanotransduction in vitro with a focus on the effects of connexin ablation and the role of cadherins, respectively. To complement this series of reviews, we have interviewed Werner Franke, whose systematic documentation the tissue-specific complexity of desmosome composition and pioneering discovery of the cardiac area composita junction greatly facilitated elucidation of the role of desmosomal components in the pathophysiology of human heart disease.

First annual Mario S. Verani, MD, Memorial lecture: clinical value of myocardial perfusion imaging in coronary artery disease.  


I am honored to give this lecture in memory of Dr Mario S. Verani, a friend and a respected colleague in the field of nuclear cardiology. Dr Verani made many immense contributions to the field of nuclear cardiology during his lifetime. He was a pioneer in the field of pharmacologic stress imaging and played a leading role in validating the utility of intravenous adenosine infusion for stress imaging in detecting significant coronary stenoses and assessing prognosis. He and his colleagues at Baylor reported that pharmacologic stress imaging could separate high- and low-risk patient subsets after acute myocardial infarction, particularly among patients who underwent thrombolytic therapy. He informed us that certain drugs that patients took could influence perfusion defect severity. This work led to a clinical study showing that ischemic defect size could be substantially reduced with medical therapy in patients who had recently had an acute infarction. An outcome of this observation was the launching of the INSPIRE (adenosINe technetium-99m Sestamibi single-photon emission computed tomography Post-InfaRction Evaluation) trial in which postinfarction patients are randomized to medical therapy or revascularization. Dr Verani was an able debater when assigned the position for advocating for stress radionuclide perfusion imaging against stress echocardiography. He engaged in these debates with substantial knowledge but always with a touch of humor. Dr Verani's courage was an inspiration to all of us during his illness. His legacy as a pioneer will endure as the field of nuclear cardiology continues to mature and expand. PMID:14569247

Was Abraham Lincoln gay?  


Scholars and historians are blind to Lincoln's same-sex inclinations in part because of a personal aversion to male homosexuality, but more importantly because they fail to perceive the vast differences between the sexual culture of antebellum America and that of our own time, especially in regard to male-male physical and emotional intimacy. This article brings those differences to light and sets Lincoln's life in the context of the sexual culture of his own time. This enables one to see that Lincoln's same-sex sexuality was not only unproblematic, but commonplace, if not typical, in his day. Revising the Myth of Lincoln in regard to his same-sex inclinations will have a positive effect on contemporary culture, especially on the education and socialization of young boys. PMID:20924927

Reading Like a Historian: Abraham Lincoln  

NSDL National Science Digital Library

In this lesson, students analyze primary source documents and engage in a Structured Academic Controversy in an effort to answer the central historical question: Was Lincoln a racist? Students answer guiding questions about 4 documents: 1) Stephen Douglas debating Lincoln on race, 2) Lincolnâs retort to Douglas, 3) young Lincolnâs letter to a friend, and 4) a pro-slavery argument by John Robinson. Students then divide into groups of 4 and into pairs A and B within each group. Each pair presents the argument to the other that Lincoln was/was not racist; only at the end do students abandon their previous positions, reach consensus as a group, and defend that view in a final class discussion.

When Sam Goudsmit was 23, he and George Uhlenbeck hypothesized that the electron had spin. Sam was a well-known atomic physicist working at the University of Michigan when World War II began. During the war he first worked on radar at the MIT Radiation Lab, and then in the waning days of the war in Europe he led a mission to determine how far the Nazis had gotten in developing an atomic bomb. After chairing the Physics Department at Brookhaven, in 1950 APS named Goudsmit Managing Editor of Physical Review and Reviews of Modern Physics; in 1966 he was named Editor-in-Chief. He founded Physical Review Letters in 1958.

Mario Bunge's Materialist Theory of Mind and Contemporary Cognitive Science  

NASA Astrophysics Data System (ADS)

Bunge's writings on the mind-body problem provide a rigorous, analytical antidote to the persistent anti-materialist tendency that has characterized the history of philosophy and science. Bunge gives special attention to dualism and its shortcomings, and this attention is welcome in view of the resurgence of the doctrine today. However, I focus my comments selectively on Bunge's more controversial, provocative claims, not to dismiss them, but to engage with them seriously. For example, a difficulty arising from Bunge's rhetorical style and its undoubted virtues is that not all the targets of his selfconfessed "bashings" (2010, xi) are equally deserving. For example, Bunge suggests "most contemporary philosophers of mind are indifferent to psychology, or are remarkably uninformed about it". This charge cannot be sustained today in light of the work of foremost philosophers today.

Abraham Pais Prize Talk: The Joy of History  

NASA Astrophysics Data System (ADS)

Physicists and historians of physics share a common goal, the quest for understanding, but their objects are different: Physicists attempt to understand Nature, while historians attempt to understand the past, finding both the challenge and joy of history in exploring the contingencies of historical events, their dependence on scientific, biographical, sociopolitical, cultural, and other factors, and shaping them into a coherent narrative. My first example will focus on the history of the photon concept, in particular on the work of Arthur Holly Compton between 1916 and 1922 that led to his discovery of the Compton effect, whose understanding ultimately rested on a close examination of his laboratory notebooks. I will then turn to two episodes in the history of nuclear physics. The first deals with a controversy between 1922 and 1927 between Ernest Rutherford and James Chadwick at the Cavendish Laboratory in Cambridge and Hans Pettersson and Gerhard Kirsch at the Institute for Radium Research in Vienna that involved their fundamentally different experimental observations and theoretical interpretations of the artificial disintegration of nuclei whose resolution could only be understood after uncovering crucial correspondence between the protagonists. The second episode traces George Gamow's creation and development of the liquid-drop model of the nucleus in 1928 and 1929 and its subsequent development in two stages, first by Werner Heisenberg and Carl Friedrich von Weizsäcker from 1933 to 1936, and second by Niels Bohr and Fritz Kalckar in 1936 and 1937, both of which merged in the minds of Lise Meitner and Otto Robert Frisch at the end of 1938 to yield the correct interpretation of nuclear fission, an act of creation whose understanding rested on a detailed analysis of the published literature.

Baring the soul: Paul Bindrim, Abraham Maslow and 'nude psychotherapy'.  


Nude psychotherapy is one of the most flamboyant therapeutic techniques ever developed in American psychology. Largely forgotten today, the therapy was an academic and popular sensation upon its introduction in 1967. Developed by psychologist Paul Bindrim, the therapy promised to guide clients to their authentic selves through the systematic removal of clothing. This paper explores the intellectual, cultural and ethical context of nude therapy and its significance as a form of unchurched spirituality. Although nude therapy has an indisputable tabloid character, it is also rooted in a long-standing academic search for authenticity and ultimate meaning through science. Bindrim's career demonstrates the historically long-standing interweaving of spirituality and science within American psychology while simultaneously highlighting the field's extraordinary capacity for adaptive reinvention.

"Towering genius disdains a beaten path" Abraham Lincoln.  


We see nursing leadership existing at all levels in nursing...all nurses leading. Nurse executives within academic health environments across Canada will be influencing health policy directions and dialogue within the profession nationally. They will be contributing to the development of a national agenda for nursing practice, education, research and leadership. These nurse executives will lead in a way that makes an invigorating impact on human service in health care environments and they will be dedicated to preparing the nursing leaders of tomorrow. The Academy of Canadian Executive Nurses will connect with the Office of Nursing Policy, Canadian Nurses Association, Canadian Association of University Schools of Nursing, Association of Canadian Academic Health Care Organizations and others to develop position papers regarding key issues such as patient safety, health human resource planning and leadership in the Canadian health care system. Our definition of professional nursing practice, fully integrated with education and research, will be advanced through these endeavours. The end result of a strong individual and collective voice will be improved patient outcomes supported by professional nursing practice in positive practice environments. This paper is intended to stimulate dialogue among nursing leaders in Canada, dislodge us from a long and traditional path, and place us firmly in a new millennium of leadership for the profession and practice of nursing, a style of leadership that is needed, wanted and supported by nurses and the clients we serve. It is the responsibility of those of us who lead in academic health science centres to be courageous for the students we support, the puactitioners we lead and the renewal of the profession. We are the testing ground for nursing research, and need to be the source of innovation for nursing practice. It is incumbent on us to leap forward to engage a new vision of the professional practice of nursing with a reconfigured work design and work environment compatible with the new economy, workplace and workforce.

Adolphe Abrahams memorial lecture, 1988. Exercise and lifestyle change.  


While the evidence for a clustering of health habits is not particularly strong, there are both pedagogic and economic arguments in favour of a multifaceted approach to health education. The present review thus examines the impact of regular physical exercise upon other forms of health behaviour, testing the extent to which an activity programme can be a catalyst of improved lifestyle in both primary and secondary preventive therapy. The conceptual framework of health promotion is examined with particular reference to the models of Skinner, Becker, Fishbein, Triandis and Rokeach. Certain differences are noted between the decision to exercise and the marketing decisions for which Fishbein's model was originally designed. Nevertheless, in its later modifications, it provides a basic framework for understanding how human lifestyle is shaped. Theoretical mechanisms are suggested whereby exercise could influence such behaviours as cigarette smoking, alcohol consumption and drug usage, seat-belt usage, hypertension, body mass, lipid profile, promiscuous sexual behaviour, the carrying of lethal weapons, and acceptance of regular preventive medical examinations. The empirical evidence from both cross-sectional and longitudinal experiments shows a relatively weak association between exercise habits and other desirable forms of health behaviour. Moreover, it is arguable that other forms of health intervention such as smoking withdrawal or dieting might be equally effective as a primary change agent, and much of the observed association between exercise and other health habits could be attributable to a common dependence on demographic and socio-economic factors. On the other hand, the apparent weakness of associations may arise in part from difficulties in measuring both habitual physical activity and other forms of health behaviour, with a resultant attenuation of correlations. Possibly, a stronger association between exercise participation and other favourable health habits would be uncovered if attention were focused upon those forms of endurance exercise currently thought to enhance cardiac health. Given that moderate endurance exercise is also positive and pleasant advice, further examination of the potential of multifaceted but exercise-centered health promotion programmes appears warranted.

The uncontrolled releases of waste effluents to large water bodies have deleterious effects both on water quality and aquatic life. Kano, an industrial city in Nigeria has the largest number of tanneries in the country is facing the problems of impairment of water quality. Levels of heavy metals (Cu, Co, Zn, Mn, Pb, Fe and Cr) were determined using Atomic Absorption spectrophotometric methods. pH, Redox potential (Eh), Temperature, Dissolve Oxygen (DO), Total Dissolve Solid, sulphate, nitrate and phosphate were also determined. Results showed high levels of Cr (2.70±0.57 to 3.12±0.69 mg L-1), Fe (1.21±0.13 to 1.61±0.41 mg L-1) and these values were found to be significantly higher than the maximum permissible limits of FEPA (p<0.05). Levels of Mn, Cu, Zn, Pb and Co were within the minimum permissible limits for effluent discharged into rivers. Increases, in concentrations of heavy metals with distance from point source up to a distance of 400 metres were observed. While anion concentration decreased with distance from point source up to a distance of 400 m. Adherence to pollution control measures and effluent pre-treatment should be enforced in the industries.

Abraham Pais Prize for History of Physics Talk: Shelter Island, Pocono, Oldstone, 1947-49, Revisited  

NASA Astrophysics Data System (ADS)

The historic June 1947 Shelter Island Conference was the first of three small conferences on theoretical physics sponsored by the National Academy of Sciences. It opened with a report of the results of Lamb and Retherford's and those of Nafe, Nelson and Rabi's experiments on the spectrum of hydrogen. The challenge to explain the accurate numbers they had obtained stimulated a renewed interest in quantum electrodynamics (QED) and became the point of departure for the post World War II developments in quantum field theory: effective Lorentz invariant computational methods, Feynman diagrams, renormalization theory. The recent discovery of Hans Bethe's extensive notes on the Shelter Island conference allows a reconsideration of the role played by Kramers, Oppenheimer and Weisskopf in these developments. The 1948 Pocono Conference at which Schwinger and Feynman presented their formulation of QED, and the 1949 Oldstone conference, at which Dyson summarized his researches and his views regarding renormalizability, give proof of the deep changes in the conceptualization, description and representation of nature that had been brought about by the work of Weisskopf, Schwinger, Feynman, and Dyson.

Abraham Lincoln's suit against a medical imposter who assaulted his client.  


In 1851, A. Lincoln, Esquire represented Edward Jones who charged in a law suit that his attending physician had assaulted him. Jones, also a lawyer, had sharply questioned Dr. Joseph S. Maus about his claims of attendance and graduation from Philadelphia's Jefferson Medical College, an allopathic medical school. Jones claimed that Maus became enraged at his persistent questioning and attacked him. In turn, Maus denied the allegation. He said that he was merely defending himself from Jones' blows with a large cane. Lincoln's legal approach was to argue about the state of medical education and whether Maus had really graduated from Jefferson Medical College. Acting as a peacemaker, he finally arranged to settle the dispute between Jones and Maus out of court. PMID:11554501

Playing Super Mario induces structural brain plasticity: gray matter changes resulting from training with a commercial video game.  


Video gaming is a highly pervasive activity, providing a multitude of complex cognitive and motor demands. Gaming can be seen as an intense training of several skills. Associated cerebral structural plasticity induced has not been investigated so far. Comparing a control with a video gaming training group that was trained for 2 months for at least 30 min per day with a platformer game, we found significant gray matter (GM) increase in right hippocampal formation (HC), right dorsolateral prefrontal cortex (DLPFC) and bilateral cerebellum in the training group. The HC increase correlated with changes from egocentric to allocentric navigation strategy. GM increases in HC and DLPFC correlated with participants' desire for video gaming, evidence suggesting a predictive role of desire in volume change. Video game training augments GM in brain areas crucial for spatial navigation, strategic planning, working memory and motor performance going along with evidence for behavioral changes of navigation strategy. The presented video game training could therefore be used to counteract known risk factors for mental disease such as smaller hippocampus and prefrontal cortex volume in, for example, post-traumatic stress disorder, schizophrenia and neurodegenerative disease.

"To care for him who shall have borne the battle and for his widow and his orphan" (Abraham Lincoln): the Department of Veterans Affairs polytrauma system of care.  


The initiation of combat in Iraq and Afghanistan has resulted in a new cohort of active-duty service members and veterans seeking rehabilitation care through the U.S. Department of Veterans Affairs (VA). Service members injured in combat most often sustain multiple injuries (polytrauma) and require a unique service delivery model to meet their needs. The VA recognized this need and responded with the development of the Polytrauma System of Care (PSC). This national system of care balances access and expertise to provide specialized life-long care to the combat injured. The PSC is comprised of: 4 specialized regional rehabilitation centers that are accredited in brain injury by the Commission on Accreditation of Rehabilitation Facilities; 21 specialized outpatient and subacute rehabilitation programs; designated polytrauma teams at smaller, more remote VA facilities; and a point of contact at all other VA facilities. In addition, the PSC has developed a proactive case-management model, a specialized telehealth network, guidelines for long-term follow-up, and services for those individuals who are unable to return home. The following commentary and articles provide additional detail on this new and unique system of care. PMID:18164348

The momentum of an electromagnetic wave inside a dielectric  

SciTech Connect

The problem of assigning a momentum to an electromagnetic wave packet propagating inside an insulator has become known under the name of the Abraham–Minkowski controversy. In the present paper we re-examine this issue making the hypothesis that the forces exerted on an insulator by an electromagnetic field do not distinguish between polarization and free charges. Under this assumption we show that the Abraham expression for the radiation mechanical momentum is highly favored. -- Highlights: •We discuss an approximation to treat electrodynamics of a dielectric material. •We support the Abraham form for the electromagnetic momentum. •We deduce Snell’s law from the conservation of the Abraham momentum. •We show how to deal with the electric field discontinuity at the dielectric boundary.

Radiation reaction by massive particles and its nonanalytic behavior  

NASA Astrophysics Data System (ADS)

We derive a massive analog of the Abraham-Lorentz-Dirac equation, i.e., the equation of motion of a relativistic charged particle with a radiation reaction term induced by emissions of massive fields. We show that the radiation reaction term has a nonanalytic behavior as a function of the mass M of the radiation field and that both expansions with respect to M and 1/M are generally invalid. Hence the massive Abraham-Lorentz-Dirac equation cannot be written as a local equation with derivative expansions. We especially investigate the radiation reaction in three specific motions: uniform acceleration, a circular motion, and a scattering process.

Radiation pressure of light pulses and conservation of linear momentum in dispersive media.  


We derive an expression for the Minkowski momentum under conditions of dispersive susceptibility and permeability, and compare it to the Abraham momentum in order to test the principle of conservation of linear momentum when matter is present. We investigate cases when an incident pulse interacts with a variety of structures, including thick substrates, resonant, free-standing, micron-sized multilayer stacks, and negative index materials. In general, we find that for media only a few wavelengths thick the Minkowski and Abraham momentum densities yield similar results. For more extended media, including substrates and Bragg mirrors embedded inside thick dielectric substrates, our calculations show dramatic differences between the Minkowski and Abraham momenta. Without exception, in all cases investigated the instantaneous Lorentz force exerted on the medium is consistent only with the rate of change of the Abraham momentum. As a practical example, we use our model to predict that electromagnetic momentum and energy buildup inside a multilayer stack can lead to widely tunable accelerations that may easily reach and exceed 10(10) m/s(2) for a mass of 10(-5) g. Our results suggest that the physics of the photonic band edge and other similar finite structures may be used as a testing ground for basic electromagnetic phenomena such as momentum transfer to macroscopic media.

A campaign of absolute gravity (AG) measurements was conducted with both FG5 and A10 meters on Ross Island and in Terra Nova Bay in November and December 2011. It resulted from a collaboration between Danish, French, Italian, New Zealand and US agencies and institutes, under the POLENET program. For the second time in 2 years, AG was measured at McMurdo Station and Scott Base. For the fifth time in 21 years, it was measured at Mario Zucchelli Station. Moreover, AG field observations were initiated at various GPS stations of the A-NET network. We will report on the very last campaign, show the gravity trends at McMurdo Station, Scott Base and Mario Zucchelli Station, and describe how they compare to estimates of the gravity variation derived from space measurements by the GRACE twin satellites.

Radiation pressure on submerged mirrors: implications for the momentum of light in dielectric media.  


Radiation pressure measurements on mirrors submerged in dielectric liquids have consistently shown an effective Minkowski momentum for the photons within the liquid. Using an exact theoretical calculation based on Maxwell's equations and the Lorentz law of force, we demonstrate that this result is a consequence of the fact that conventional mirrors impart, upon reflection, a 180 degrees phase shift to the incident beam of light. If the mirror is designed to impart a different phase, then the effective momentum will turn out to be anywhere between the two extremes of the Minkowski and Abraham momenta. Since all values in the range between these two extremes are equally likely to be found in experiments, we argue that the photon momentum inside a dielectric host has the arithmetic mean value of the Abraham and Minkowski momenta. PMID:19532504

Dependence of the Radiation Pressure on the Background Refractive Index  

NASA Astrophysics Data System (ADS)

The 1978 experiments by Jones and Leslie showing that the radiation pressure on a mirror depends on the background medium refractive index have yet to be adequately explained using a force model and have provided a leading challenge to the Abraham form of the electromagnetic momentum. Those experimental results are predicted for the first time using a force representation that incorporates the Abraham momentum by utilizing the power calibration method employed in the Jones and Leslie experiments. With an extension of the same procedure, the polarization and angle independence of the experimental data are also explained by this model. Prospects are good for this general form of the electromagnetic force density to be effective in predicting other experiments with macroscopic materials. Furthermore, the rigorous representation of material dispersion makes the representation important for metamaterials that operate in the vicinity of homogenized material resonances.

[Circumcision from a historical perspective].  


Male circumcision has been practiced by many tribes in different continents. The oldest image of a circumcision dates from 2300 BC and was found in Egypt. In the Jewish religion circumcision symbolizes the covenant between God and Abraham. Despite the fact that Jesus of Nazareth was circumcised, circumcision has never been part of Christianity. Circumcision is not mentioned in the Koran; the practice of circumcision in Islam is attributed to Abraham, who is considered by muslims to be one of the prophets. From the middle of the nineteenth century circumcision was performed for medical reasons. Throughout the centuries, from the time of the Bible, many methods for performing circumcision have been described, and a few to undo it by restoring the prepuce. PMID:11155508

Maslow (1969a) amended his model, placing self-transcendence as a motivational step beyond self-actualization. Objections to this reinterpretation are considered. Possible reasons for the persistence of the conventional account are described. Recognizing self-transcendence as part of Maslow's hierarchy has important consequences

Surface deformation of a thin liquid film under infrared radiation  

NASA Astrophysics Data System (ADS)

A thin layer of decane liquid floating above the surface of water is compressed in thickness when exposed to a radiation by an infrared laser in normal incidence. This is believed to result from an inward radiation pressure received by the decane film as light crosses successively the air-decane interface and the decane-water interface. The experimental results support Abraham's formulation for the momentum of light. Thermo-effects may also contribute.

Total synthesis and proof of relative stereochemistry of (-)-aureonitol.  


Two trisubstituted epimeric tetrahydrofurans, 1 and 2, have been synthesized in order to confirm the relative stereochemistry in the natural product aureonitol. The key step in the synthesis of 1 and 2 involved a stereoselective intramolecular allylation of an allylsilane with an aldehyde, which introduced the stereotriad in the five-membered ring. The major tetrahydrofuran diastereoisomer 18 from this cyclization reaction was subsequently elaborated to tetrahydrofuran 1. Its 3-epimer (2) was then prepared from 1 via an oxidation-reduction sequence. Compound 1 exhibits identical (1)H NMR data to those reported for aureonitol, which was isolated from Helichrysum aureonitons by Bohlmann in 1979, whereas the (1)H NMR data for 2 are markedly different. The (1)H NMR data (in CDCl3, CD3OD, and C6D6) and (13)C NMR data (in CDCl3) for 1 are also identical with those reported for a natural product isolated from various Chaetomium sp. by Abraham, Seto, and Teuscher. These findings support Abraham's conclusion that the structure of aureonitol should be revised from 2 to 1. The enantioselective synthesis of 1 has also confirmed that (-)-aureonitol isolated by Abraham contains the (2S,3R,4S) absolute configuration of stereocenters on the tetrahydrofuran ring.

Type II hidden symmetries through weak symmetries for some wave equations  

NASA Astrophysics Data System (ADS)

The Type II hidden symmetries are extra symmetries in addition to the inherited symmetries of the differential equations when the number of independent and dependent variables is reduced by a Lie-point symmetry. In [Gandarias RML. Type-II hidden symmetries through weak symmetries for nonlinear partial differential equations. J Math Anal Appl 2008;348:752-9] it was shown that the provenance of the Type II Lie point hidden symmetries found for differential equations can be explained by considering weak symmetries or conditional symmetries of the original PDE. In this paper we analyze the connection between one of the methods analyzed in [Abraham-Shrauner B, Govinder KS. Provenance of Type II hidden symmetries from nonlinear partial differential equations. J Nonlin Math Phys 2006;13:612-22] and the weak symmetries of some partial differential equations in order to determine the source of these hidden symmetries. We have considered some of the models presented in [Abraham-Shrauner B, Govinder KS. Provenance of Type II hidden symmetries from nonlinear partial differential equations. J Nonlin Math Phys 2006;13:612-22], as well as the linear two-dimensional and three-dimensional wave equations [Abraham-Shrauner B, Govinder KS, Arrigo JA. Type II hidden symmetries of the linear 2D and 3D wave equations. J h Phys A Math Theor 2006;39:5739-47].

Tests with superconducting re-entrant cavities for transducer applications in gravitational wave detectors  

NASA Astrophysics Data System (ADS)

We studied the niobium re-entrant cavity utilized by the Australian group in the Niobe gravitational wave detector. Instead of using their non-contact re-entrant cavity, we plan to change it to a closed one to be used in the parametric transducers of the Brazilian Mario Schenberg detector. The performance of the transducer depends on some cavity parameters such as the electrical Q and the electrical coupling. We measured the resonant frequency and the loaded electrical Q as a function of the probe position in a closed niobium ~15 GHz cavity operating at 4.2 K.

The International Conferences on Alpine Meteorology: Characteristics and trends from a 57-year-series of scientific communication  

NASA Astrophysics Data System (ADS)

General information is assembled about origin, conduct and written documentation concerning the full series of 29 biennial International Conferences on Alpine Meteorology (ICAM) between 1950 and 2007. The slowly evolving format of interactive scientific communication is apparent since the series was started by Mario Bossolasco, a visionary geophysical scientist. A comparison with the related mountain meteorology conference series organized by the American Meteorological Society helps to put the European achievement in perspective. Such a compact bookkeeping activity is considered essential for valuing properly the considerable impact of a regular, focussed, single-session conference series like ICAM for issues like international cooperation, practical education of students, and scientific advancement in general.

Ponzo Illusion Experiment  

NSDL National Science Digital Library

This is the entry page for the Ponzo Illusion. The Ponzo illusion, named after Italian artist and psychologist Mario Ponzo (1882-1960), is one of a set of geometrical illusions that produce misjudgment of relative line length. This misjudgment reflects our tendency to perceive two-dimensional geometric illustrations in certain contexts as if they were three-dimensional objects in our environment. Participants adjust the length of one of the horizontal lines until they perceive the two lines as being of equal length.

Sorption of untreated and humic acid coated silver nanoparticles to environmental and model surfaces  

NASA Astrophysics Data System (ADS)

The environmental fate of engineered nanoparticles is controlled their colloidal stability and their interaction with different environmental surfaces. Little is known about sorption of nanoparticles to environmental surfaces under quasi-equilibrium conditions. Nevertheless, sorption isotherms may also be a valuable means of studying nanoparticle-sorbent interactions. We investigated sorption of engineered silver nanoparticles (nAg) from stable and unstable suspensions in presence and absence of natural organic matter (NOM) to model surfaces (sorbents with specific chemical functional groups) and environmental materials (plant leaves and sand). Morphology and nanomechanical parameters of the surfaces covered with nanoparticles were assessed using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The sorption of nAg from stable suspensions and in absence of NOM was non-linear and best described by a Langmuir model, where Langmuir coefficients varied with sorbent surface chemistry, which suggests monolayer sorption (Abraham et al. 2013). For nAg sorption from an unstable suspension, the sorption isotherms did not follow any classical sorption models, suggesting interplay between aggregation and sorption (Abraham et al. 2013). In contrast, sorption was strongly suppressed and exhibited linear sorption isotherms in the presence of NOM. The difference in sorption isotherms suggests predominance of different sorption mechanisms depending on presence or absence of NOM, which can be only partly explained by the NOM coating alone. On the basis of the current results, a partial release of NOM coating for sorption of certain surfaces cannot be excluded. The validity of the Langmuir isotherm suggests monolayer sorption, which can be explained by the blocking effect due to electrostatic repulsion of individual nanoparticles. In unstable suspensions, aggregates are instead formed in suspension, formed on the surface and then sorbed, or formed in both ways.

Type-II hidden symmetries through weak symmetries for nonlinear partial differential equations  

NASA Astrophysics Data System (ADS)

The Type-II hidden symmetries are extra symmetries in addition to the inherited symmetries of the differential equations when the number of independent and dependent variables is reduced by a Lie point symmetry. In [B. Abraham-Shrauner, K.S. Govinder, Provenance of Type II hidden symmetries from nonlinear partial differential equations, J. Nonlinear Math. Phys. 13 (2006) 612-622] Abraham-Shrauner and Govinder have analyzed the provenance of this kind of symmetries and they developed two methods for determining the source of these hidden symmetries. The Lie point symmetries of a model equation and the two-dimensional Burgers' equation and their descendants were used to identify the hidden symmetries. In this paper we analyze the connection between one of their methods and the weak symmetries of the partial differential equation in order to determine the source of these hidden symmetries. We have considered the same models presented in [B. Abraham-Shrauner, K.S. Govinder, Provenance of Type II hidden symmetries from nonlinear partial differential equations, J. Nonlinear Math. Phys. 13 (2006) 612-622], as well as the W=VV equations of associativity in two-dimensional topological field theory which reduces, in the case of three fields, to a single third order equation of Monge-Ampère type. We have also studied a second order linear partial differential equation in which the number of independent variables cannot be reduced by using Lie symmetries, however when is reduced by using nonclassical symmetries the reduced partial differential equation gains Lie symmetries.

Variability of surface ocean radiocarbon and stable isotopes in the southwestern Pacific  

NASA Astrophysics Data System (ADS)

We present high-precision radiocarbon (?14C) results and stable isotope (?18O and ?13C) records for a coral from Heron Island (23°S, 152°E) and new stable isotope (?18O and ?13C) records for annual coral bands from Abraham Reef (22°S, 153°E) in the southern Great Barrier Reef studied earlier [Druffel and Griffin, 1993]. These tracers provide unique information on the regional water mass history, and together these data allow us to constrain the variability of circulation in the upper Pacific over the past four centuries. First, we observe decreases in ?18O of coral from Abraham Reef and Heron Island, indicating an increase in sea surface temperature and/or a decrease in surface salinity since 1850. Second, the small Suess effect value (?14C decrease from 1880 to 1955, due mostly to fossil fuel CO2) observed previously at Abraham Reef[Druffel and Griffin, 1993] is confirmed in the measurements reported here from the Heron Island coral. This value is low compared to those observed in other areas of the ocean [Druffel, 1997; Druffel and Linick, 1978; Nozaki et al., 1978] between 1880 and 1955. Third, we report alterations in the correlation between El Niño events and the occurrence of low ?14C, which is indicative of long-term change(s) in circulation in the SW Pacific. The ?14C shifts reported here are not large, but even small temporal changes in prebomb ?14C suggest that important changes in the large-scale state of the ocean have occurred, such as a temporal change in circulation.

Isothermal retention indices on poly(3-cyanopropylmethylsiloxane) stationary phases.  


Experimental isothermal retention indices (I) at 348, 363, 378 and 393 K of 52 solutes of varied polarity on seven different poly(cyanopropylmethylsiloxane) stationary phases with cyanopropyl group percentages between 0% and 75% have been determined by a well-proven, accurate method. Some of these I values were obtained on new stationary phases with cyanopropyl percentages never used before. The influence of column temperature and polymer polarity on I was thoroughly investigated. Finally, retention models were developed relating I values to physicochemical and molecular properties by multiple linear regression. The best model of retention index prediction for the proposed cyanosilicones involves the Abraham's descriptors. PMID:18992890

Relaxation dynamics of a system with a grain boundary  

NASA Astrophysics Data System (ADS)

Recently an interesting phase transition scenario in the context of a planar Ising system with a grain boundary was revealed [Abraham , Phys. Rev. Lett. 93, 076101 (2004)]. In this paper we study in more detail the relaxation dynamics of this system and show how the grain boundary acts as a guide spatially confining matter transport. This is done by performing simulations using the continuous time Monte Carlo algorithm with Kawasaki dynamics. We also set up the problem as a solid-on-solid model and formulate corresponding Langevin equations for the dynamics in two cases, with and without matter conservation.

On Whether Angular Momentum in Electric and Magnetic Fields Radiates to Infinity  

NASA Technical Reports Server (NTRS)

The Feynman Disk experiment and a related thought experiment with a static magnetic field and capacitor are studied. The mechanical torque integrated over time (angular impulse) is related to the angular momentum in the electric/magnetic field. This is not called an electromagnetic field since quasi-static as well as electromagnetic effects are included. The angular momentum in the electric/magnetic field is examined to determine its static and radiative components. This comparison was then examined to see if it clarified the Abraham-Minkowski paradox.

The applicability range of different forms of the radiation friction force in the ultrarelativistic electron interaction with electromagnetic wave (exact solutions)  

NASA Astrophysics Data System (ADS)

When the effects of radiation reaction dominate the interaction of electrons with intense laser pulses, the electron dynamics changes qualitatively. The adequate theoretical description of this regime becomes crucially important with the use of the radiation friction force either in the Lorentz-Abraham-Dirac form, which possess unphysical runaway solutions, or in the Landau-Lifshitz form, which is a perturbation valid for relatively low electromagnetic wave amplitude. The goal of the present paper is to find the limits of the Landau-Lifshitz radiation force applicability in terms of the electromagnetic wave amplitude and frequency.

Dynamics of emitting electrons in strong laser fields  

NASA Astrophysics Data System (ADS)

A new derivation of the motion of a radiating electron is given, leading to a formulation that differs from the Lorentz-Abraham-Dirac equation and its published modifications. It satisfies the proper conservation laws. Particularly, it conserves the generalized momentum, eliminating the symmetry-breaking runaway solution. The equation allows a consistent calculation of the electron current, the radiation effect on the electron momentum, and the radiation itself, for a single electron or plasma electrons in strong electromagnetic fields. The equation is then applied to a simulation of a strong laser pulse interaction with a plasma target. Some analytical solutions are also provided.

Mercedes-Benz water molecules near hydrophobic wall: Integral equation theories vs Monte Carlo simulations  

PubMed Central

Associative version of Henderson-Abraham-Barker theory is applied for the study of Mercedes–Benz model of water near hydrophobic surface. We calculated density profiles and adsorption coefficients using Percus-Yevick and soft mean spherical associative approximations. The results are compared with Monte Carlo simulation data. It is shown that at higher temperatures both approximations satisfactory reproduce the simulation data. For lower temperatures, soft mean spherical approximation gives good agreement at low and at high densities while in at mid range densities, the prediction is only qualitative. The formation of a depletion layer between water and hydrophobic surface was also demonstrated and studied.

Radiation reaction in ultrarelativistic laser-spinning electron interactions  

NASA Astrophysics Data System (ADS)

The intensity of ultra-short pulse lasers has reached 1022 W/cm2 owing to the advancements in laser technology. The large radiation from the electron behaves something like resistance in this ultrarelativistic laser-electron interaction. This effect is called the "radiation reaction". The equation of motion with the radiation reaction is known as the Lorentz-Abraham-Dirac equation; however, this equation does not incorporate the spin property. In laser plasmas, classical physics descriptions are preferred for simulations. This paper discusses how to describe the radiation reaction of a spinning relativistic electron in classical dynamics.

[The nursing team and Maslow: (dis)satisfaction in the work].  


This text tries to understand the Nursing team and their (dis)satisfactions in the work. We consider the association with the theory of basic human needs of Abraham Maslow as a way to systemize and to comprehend the recurrent situations and the day-by-day Nursing issues. The necessities are structuralized hierarchically in physiological, security, social, auto-esteem and auto-accomplishment indicating the degree of satisfaction (from the disease to the fullness) of an individual or group. The advantage of this approach consists of being able to use the solid, depth and rich Maslow theory in concrete and particular situations of the Nursing team. PMID:17340737

Diagnosing the dead: the retrospective analysis of genetic diseases.  


The suspected presence of hereditary disease in important historical and political figures has interested researchers for many decades. Whether Abraham Lincoln suffered from Marfan syndrome, if George III became 'mad' because he inherited variegate porphyria, and if the Romanov dynasty collapsed because the heir Alexei inherited haemophilia are important questions; physical illness can adversely affect the ability of leaders to function within the social and political realm of their day. This article will outline an approach to such a medical-historical analysis including assessment of hereditary predisposition, family history and the use of DNA technology to confirm or deny the clinical suspicions of the investigator.

Effort thrombosis: recognition and management while underway.  


Effort thrombosis of the axillary and subclavian veins is an uncommon cause of upper extremity swelling. Prompt recognition and treatment of this disorder is important in order to minimize the complications of pulmonary embolism and postphlebitic syndrome that can occur with this condition. This can be very challenging while underway or in the field. A sailor who developed effort vein thrombosis while underway on board the aircraft carrier USS Abraham Lincoln is presented to review the presentation and management of this disorder, particularly as it applies to active duty military personnel.

Chloroform-induced insanity defence confounds lawyer Lincoln.  


During an 1857 trial, the defence claimed that the accused should be absolved of wilful murder because an overdose of chloroform during surgery induced insanity. In a rare appearance as a prosecutor, Abraham Lincoln tried the case for the State of Illinois. Expert medical witnesses testified about the side effects of chloroform and chloroform-induced insanity. Significantly, Lincoln was not knowledgeable about medical jurisprudence and overlooked potential sources of evidence and expert witnesses. Defence lawyers presented an impressive array of physicians to testify about insanity, about chloroform and about the results of an overdosage during anaesthesia. Considering the state of scientific knowledge at the time, the trial was notable. PMID:11619819

Video-game epilepsy: a European study.  


With the introduction of Nintendo video-games on a large scale, reports of children having seizures while playing suggested a possible specific, provocative factor. Although 50% of the photosensitive patients are also sensitive to a 50-Hz television, nonphotosensitive patients with a history of video-game seizures were described as well. The question arises whether this is a mere coincidence, provoked by fatigue and stress, is related to the reaction to the television screen itself, or depends on the movement and color of the pictures of this specific game. A European study was performed in four countries and five sites. All patients were selected because of a history of television, video- or computer-game seizures, with a history of sun-light-, discotheque-, or black and white pattern-evoked seizures, or were already known to be sensitive to intermittent photic stimulation. A total of 387 patients were investigated; 220 (75%) were female and 214 (55%) of those were < 18 years of age. After a routine examination, intermittent photic, pattern, and television stimulation were performed in a standardized way. The patients were investigated with Super Mario World and a standard relatively nonprovocative TV program, both on a 50- and 100-Hz television. Regardless of the distance, Super Mario World proved to be more provocative than the standard program (Wilcoxon, p < 0.05). Eighty-five percent showed epileptiform discharges evoked by intermittent photic stimulation. Forty-five percent of patients were 50-Hz television sensitive and 26% were 100-Hz television sensitive. Pattern sensitivity was found in 28% of patients. The patients, referred because of a television, video- or computer-game seizure, were significantly more sensitive to pattern and to the 50-Hz television (chi square, p < 0.001). More patients are sensitive when playing Super Mario, compared with the standard program (Wilcoxon, p = 0.001) and more sensitive with playing versus viewing (p = 0.016). Of the patients who were referred because of seizures in front of the television, or evoked by a video- or computer game, 14% proved not to be photosensitive. Although no difference in age or use of medication was found, twice as many men were found in this nonphotosensitive group. PMID:10487177

Biorelevant pKa (37?C) predicted from the 2D structure of the molecule and its pKa at 25?C  

PubMed Central

Values of the ionization constants at 37°C, which are scarcely reported, are more meaningful for interpreting mechanisms of cellular transport by ionizable molecules and in mechanistic dissolution studies, which are often performed at the biorelevant temperature. An equation was developed where the pKa values of drug-like molecules determined at 25°C can be simply converted to values at 37°C, without additional measurement. The differences between the values, ?pKa = pKa37 ? pKa25, were linearly fitted to a function of pKa25 and the standard entropy of ionization, ?So, where the latter term was approximated by the five Abraham linear free energy solvation descriptors using multiple linear regression. The Abraham descriptors (H-bond donor and acceptor strengths, dipolar solute-solvent interactions potential, the pi- and n-electrons dispersion force, and molar volume) were determined from the 2-dimensional structure of the molecules. A total of 143 mostly drug-like molecules (207 pKa values at 25°C and at 37°C) were chosen for the study. The pKa values of many were determined here for the first time. Included were 34 weak acids, 85 weak bases, and 24 amphoteric compounds (6 ordinary ampholytes, 18 zwitterions).

Equation of motion with radiation reaction in ultrarelativistic laser-electron interactions  

NASA Astrophysics Data System (ADS)

The intensity of the ultra-short pulse lasers has reached 1022 W/cm2 owing to the advancements of laser technology. When the motion of an electron becomes relativistic, bremsstrahlung accompanies it. The energy from this bremsstrahlung corresponds to the energy loss of the electron; therefore, the motion of the electron deviates from the case without radiation. The radiation behaves something like resistance. This effect called ``radiation reaction'' or ``radiation damping'' and the force converted from the radiation is named the ``radiation reaction force'' or the ``damping force''. The equation of motion with the reaction force is known as the Lorentz-Abraham-Dirac (LAD) equation, but the solution of this equation is not physical due to the fact that it has a ``run-away'' solution. As one solution of this problem, we have derived a new equation which takes the place of the Lorentz-Abraham-Dirac equation. We will show the validity of this equation with a simple theoretical analysis.

Electromagnetic force and torque in ponderable media.  


Maxwell's macroscopic equations combined with a generalized form of the Lorentz law of force are a complete and consistent set of equations. Not only are these five equations fully compatible with special relativity, they also conform with conservation laws of energy, momentum, and angular momentum. We demonstrate consistency with the conservation laws by showing that, when a beam of light enters a magnetic dielectric, a fraction of the incident linear (or angular) momentum pours into the medium at a rate determined by the Abraham momentum density, E x H/c(2), and the group velocity V(g) of the electromagnetic field. The balance of the incident, reflected, and transmitted momenta is subsequently transferred to the medium as force (or torque) at the leading edge of the beam, which propagates through the medium with velocity V(g). Our analysis does not require "hidden" momenta to comply with the conservation laws, nor does it dissolve into ambiguities with regard to the nature of electromagnetic momentum in ponderable media. The linear and angular momenta of the electromagnetic field are clearly associated with the Abraham momentum, and the phase and group refractive indices (n(p) and n(g)) play distinct yet definitive roles in the expressions of force, torque, and momentum densities.

On some [`]duality' of the Nikodym property and the Hahn property  

NASA Astrophysics Data System (ADS)

Drewnowski and Paúl proved in [L. Drewnowski, P.J. Paúl, The Nikodým property for ideals of sets defined by matrix summability methods, Rev. R. Acad. Cienc. Exactas Fís. Nat. (Esp.) 94 (2000) 485-503] that for any strongly nonatomic submeasure [eta] on the power set of the ideal has the Nikodym property (NP); in particular, this result applies to densities dA defined by strongly regular matrices A. Grahame Bennett and the authors stated in [G. Bennett, J. Boos, T. Leiger, Sequences of 0's and 1's, Studia Math. 149 (2002) 75-99] that the strong null domain A0 of any strongly regular matrix A has the Hahn property (HP). Moreover, Stuart and Abraham [C.E. Stuart, P. Abraham, Generalizations of the Nikodym boundedness and Vitali-Hahn-Saks theorems, J. Math. Anal. Appl. 300 (2) (2004) 351-361] pointed out that the said results are in some sense dual and that the last one follows from the first one by considering the density dA (defined by A) as submeasure on and the ideal as well by identifying with the set [chi] of sequences of 0's and 1's. In this paper we aim at a better understanding of the intimated duality and at a characterization of those members of special classes of matrices A such that has NP (equivalently, A0 has HP).

Trap loss in photoassociative spectroscopy.  

NASA Astrophysics Data System (ADS)

Measurements of photoassociative spectroscopy in a gas of lithium atoms at ultralow temperatures have been carried out (E.R.I Abraham, N.W.M. Ritchie, W.I. McAlexander, and R.G. Hulet, J. Chem. Phys. 103), 7773 (1995); E.R.I Abraham, W.I. McAlexander, J.M. Gerton, R.G. Hulet, R. Côté, and A. Dalgarno, Phys. Rev. A 53, R3713 (1996).. In the experiments, photons are absorbed into high vibrational levels of excited electronic singlet and triplet states of Li2 (R. Côté, A. Dalgarno, Y. Sun, and R.G. Hulet, Phys. Rev. Lett. 74), 3581 (1995).. The excited vibrational levels decay by spontaneous emission into the vibrational continuum and the discrete vibrational levels of the ground electronic states (R. Côté and A. Dalgarno, to be published in Phys. Rev. A.). Decay into the vibrational continuum can produce atoms with sufficient kinetic energy to escape the trap, while spontaneous emission into discrete levels produces molecules no longer trapped. We explore the trap loss from spontaneous emission as a function of the trap depth as well as the excited vibrational levels considered. The analysis is conducted for the singlet and triplet transitions for both ^6Li and ^7Li isotopes.

Electromagnetic momentum and the energy-momentum tensor in a linear medium with magnetic and dielectric properties  

NASA Astrophysics Data System (ADS)

In a continuum setting, the energy-momentum tensor embodies the relations between conservation of energy, conservation of linear momentum, and conservation of angular momentum. The well-defined total energy and the well-defined total momentum in a thermodynamically closed system with complete equations of motion are used to construct the total energy-momentum tensor for a stationary simple linear material with both magnetic and dielectric properties illuminated by a quasimonochromatic pulse of light through a gradient-index antireflection coating. The perplexing issues surrounding the Abraham and Minkowski momentums are bypassed by working entirely with conservation principles, the total energy, and the total momentum. We derive electromagnetic continuity equations and equations of motion for the macroscopic fields based on the material four-divergence of the traceless, symmetric total energy-momentum tensor. We identify contradictions between the macroscopic Maxwell equations and the continuum form of the conservation principles. We resolve the contradictions, which are the actual fundamental issues underlying the Abraham-Minkowski controversy, by constructing a unified version of continuum electrodynamics that is based on establishing consistency between the three-dimensional Maxwell equations for macroscopic fields, the electromagnetic continuity equations, the four-divergence of the total energy-momentum tensor, and a four-dimensional tensor formulation of electrodynamics for macroscopic fields in a simple linear medium.

James F. T. Bugental (1915-2008).  


James F. T. Bugental died peacefully at age 92 at his Petaluma, California, home on September 18, 2008. Jim was a leading psychotherapist and a founding father, with Abraham Maslow and others, of humanistic psychology, or the "third force" (in contrast to psychoanalysis and behaviorism). Jim was also the creator, along with Rollo May, of existential-humanistic psychotherapy. Jim was born in Fort Wayne, Indiana, on Christmas Day in 1915. Jim earned his doctorate in 1948 from Ohio State University, where he was influenced by Victor Raimy and George Kelly. After a brief time on the University of California, Los Angeles (UCLA) faculty in psychology, Jim resigned in 1953 to found the first group practice of psychotherapy, Psychological Service Associates, with Alvin Lasko. With Abraham Maslow and others, Jim was a cofounder of the Journal of Humanistic Psychology (JHP) and the Association for Humanistic Psychology in 1961. Jim also wrote many books on the topic of psychotherapy during his lifetime. Jim was a great and bold spirit--his many writings and teachings are cherished today widely, and the field of psychology is much richer for his efforts. PMID:19203148

Hebrew and Latin astrology in the twelfth century: the example of the location of pain.  


The formative period of Latin and Hebrew astrology occurred virtually simultaneously in both cultures. In the second quarter of the twelfth century the terminology of the subject was established and the textbooks which became authoritative were written. The responsibility for this lay almost entirely with two scholars: John of Seville for the Latins, and Abraham ibn Ezra for the Jews. It is unlikely to have been by coincidence that the same developments in astrology occurred in these two cultures. John of Seville and Abraham ibn Ezra were both brought up within the Islamic culture of Spain, and their astrology was Arabic astrology. Moreover, some scholars have thought that John's origins were Jewish, while Ibn Ezra is known to have collaborated with Latin scholars (whose names are not recorded). It cannot be a coincidence that they forged the science of astrology for their respect co-religionists at almost the same time. Yet, very little research has been done on the possible relations between the two scholars. The purpose of this paper is to begin to explore this relationship, and to illustrate it in particular by their shared doctrine concern the location of pain. PMID:20513618

Equation of motion with radiation reaction in ultrarelativistic laser-electron interactions  

SciTech Connect

The intensity of the ultra-short pulse lasers has reached 10{sup 22} W/cm{sup 2} owing to the advancements of laser technology. When the motion of an electron becomes relativistic, bremsstrahlung accompanies it. The energy from this bremsstrahlung corresponds to the energy loss of the electron; therefore, the motion of the electron deviates from the case without radiation. The radiation behaves something like resistance. This effect called ''radiation reaction'' or ''radiation damping'' and the force converted from the radiation is named the ''radiation reaction force'' or the ''damping force''. The equation of motion with the reaction force is known as the Lorentz-Abraham-Dirac (LAD) equation, but the solution of this equation is not physical due to the fact that it has a ''run-away'' solution. As one solution of this problem, we have derived a new equation which takes the place of the Lorentz-Abraham-Dirac equation. We will show the validity of this equation with a simple theoretical analysis.

Can lightning be a noise source for a spherical gravitational wave antenna?  

SciTech Connect

The detection of gravitational waves is a very active research field at the moment. In Brazil the gravitational wave detector is called Mario SCHENBERG. Because of its high sensitivity it is necessary to model mathematically all known noise sources so that digital filters can be developed that maximize the signal-to-noise ratio. One of the noise sources that must be considered are the disturbances caused by electromagnetic pulses due to lightnings close to the experiment. Such disturbances may influence the vibrations of the antenna's normal modes and mask possible gravitational wave signals. In this work we model the interaction between lightnings and SCHENBERG antenna and calculate the intensity of the noise due to a close lightning stroke in the detected signal. We find that the noise generated does not disturb the experiment significantly.

A Nearly Complete Census Of Young Stars Distribution In The Nearest Molecular Clouds  

NASA Technical Reports Server (NTRS)

Under this grant we prepared a program of observations based on our previous plans for observations with the WIRE satellite. Our main effort was to use our WIRE plans to prepare estimates for a SIRTF Legacy Science proposal, From Molecular Cores to Planets (N. Evans, PI). For this purpose, L. Allen compiled catalogs of dense cores with and without associated stars, of stars in the youngest evolutionary stages (Class 0, I, and II), and of embedded clusters observed in the near infrared. Further, Tyler Bourke, Mario van den Ancker, and Chang Won Lee compiled and edited a refined lists of 150 isolated cores in the nearest star-forming regions within several hundred pc of the Sun, suitable for surveying with SIRTF. Our SIRTF Legacy Science proposal was selected for funding, and we are continuing with our planning for the observations.

Final Blaze of Glory  

NASA Technical Reports Server (NTRS)

This video gives an overview of planetary nebulae through a computerized animation, images from the Hubble Space Telescope (HST), and interviews with Space Telescope Science Institute Theorist Dr. Mario Livio. A computerized animation simulates a giant star as it swallows its smaller companion. HST images display various planetary nebulae, such as M2-9 Twinjet Nebula, NGC 3568, NGC 3918, NGC 5307, NGC 6826, NGC 7009, and Hubble 5. An artist's concept shows what our solar system might look like in a billion years when the Sun has burned out and cast off its outer layers in a shell of glowing gas. Dr. Livio describes the shapes of the planetary nebulae, gives three reasons to study planetary nebulae, and what the observations made by HST have meant to him. A succession of 17 HST images of planetary nebulae are accompanied by music by John Serrie.



Between Homo Sociologicus and Homo Biologicus: The Reflexive Self in the Age of Social Neuroscience  

NASA Astrophysics Data System (ADS)

The social sciences rely on assumptions of a unified self for their explanatory logics. Recent work in the new multidisciplinary field of social neuroscience challenges precisely this unproblematic character of the subjective self as basic, well-defined entity. If disciplinary self-insulation is deemed unacceptable, the philosophical challenge arises of systematically bringing together neurological, psychological, sociological, and anthropological dimensions of analysis in one framework such as dynamic systems theory; and of finding bridging concepts such as memory, social cognition, and cultural scripts that can facilitate the cross disciplinary study of the reflexive self. Relying on the systemic philosophy of science developed by Mario Bunge, this paper takes some steps in this direction.

[Speech by Carlos Matus in the presentation of Adiós, Señor Presidente].  


The text of this article was written by Carlos Matus and read aloud by him at the first presentation of his book Adiós, Señor Presidente [Goodbye, Mr. President] in Venezuela in 1987. Matus describes the problems of the governments of Latin America of that day, in order to address the growing gap between the capacity of governments to govern and the complexity of social systems. For Matus, bridging this gap requires theories, techniques, systems and methods so as to develop government projects in which the governability of the system is not less than the magnitude of its problems.

Hedgehog subwavelength hole arrays: control over the THz enhanced transmission  

NASA Astrophysics Data System (ADS)

By backing or sandwiching a holey metal layer with or between isotropic dielectric slabs, additional peaks of transmission within the long-wavelength regime arise as a result of the induced transverse magnetic (TM) or transverse electric (TE) grounded dielectric modes. A similar control of the complex surface wave modes, and thus of the extraordinary transmission (ET) peaks, is demonstrated here via anisotropic slabs in the form of a fakir's bed of nails. However, it is shown that those ET peaks formed from TE modes are suppressed because of the inherent dispersion characteristics of the free-standing grounded pins. This allows the red-shifting of the ET for the polarization parallel to the larger in-plane period of the hole array, but unlike the dielectric isotropic slab configuration, the orthogonal polarization remains inhibited. In memoriam Professor Mario Sorolla.

Julio Cortázar quotes on normal and abnormal movements: magical realism or reality?  


Together with Mario Vargas Llosa and Gabriel García Márquez, Julio Cortázar was one of the most representative authors of the Latin American magical realism genre. Within his extensive body of work, many descriptions of characters suffering physical disabilities, as well as situations suggesting such medical conditions, can be extracted. In this review, two short stories by Cortázar are presented. In the first one, the main character could easily be a man suffering from corticobasal degeneration; in the second, an old woman with symptoms suggestive of progressive supranuclear palsy is clearly depicted. Despite the fact that one of the main ingredients in Cortázar's magical realism is fiction, cases described here fit real medical conditions quite well, making it hard to believe that they represent purely fantastic descriptions rather than the product of Cortázar's inquisitive observation and the description of real patients.

Pair production in the gravitational field of a cosmic string  

NASA Astrophysics Data System (ADS)

We show that many elementary particle physics processes, such as pair production by a high energy photon, that take place in Minkowski space only if a non-uniform external field provides for momentum non-conservation, do occur in the space-time around a straight cosmic string, even though the space is locally flat and there is no local gravitational potential. We exemplify this mechanism through the evaluation of the cross section per unit length of string for the decay of a massless scalar particle into a pair of massive particles. The cross sections for this kind of processes are typically small. Nevertheless, it is interesting to realize how these reactions occur due to topological properties of space, rather than to the action of a local field. V.S. is grateful to Mario Castagnino for hospitality at the Instituto de Astronomía y Física del Espacio during a visit while this work was done.

New York State high-speed surface transportation study. Executive summary  

SciTech Connect

In 1990, New York State Governor Mario M. Cuomo created an interagency task force under the leadership of Lt. Governor Stan Lundine to investigate the potential of high speed ground transportation (HSGT) systems. the study`s objective was to assess potential rights-of-way, ridership, energy and environmental impacts, economic benefits, capital, operating, and maintenance costs, and financial viability of HSFT systems. The study builds upon and supplements previous and on-going HSGT activities conducted by the members of the interagency task force. These activities include: Maglev Technical and Economic Feasibility Study (NYSERDA); Maglev Demonstration Site Investigation (NYSTA); and New York/Massachusetts High Speed Ground Transportation Study (NYSDOT). The study is intended to verify and refine previous information and analyses and provide supplemental information and insights to be used in determining if additional investigation and activities involving HSGT are desirable for New York State.

External-PIXE analysis for the study of pigments from a painting from the Museum of Contemporary Art  

NASA Astrophysics Data System (ADS)

External Ion Beam Analysis is a useful tool for the characterization of cultural heritage objects. During the last decade, several significant collaborations have been established between Ion Beam Analysis (IBA) scientists and art or archeology professionals, demanding in-air IBA for a variety of different cultural heritage objects. In-air Particle Induced X-ray Emission (PIXE) analyses of an oil painting by the Italian painter, Mario Sironi, from the Museum of Contemporary Art of the University of São Paulo (MAC-USP), were examined. This painting is particularly interesting due to paintings on both sides (oil on canvas on the front and oil on wood on the back side). PIXE analysis helped the identification of the pigment similarities on both sides of the painting, suggesting the same authorship.

Observations of Type I X-ray Bursts from GS 1826-238 with RXTE  

NASA Technical Reports Server (NTRS)

The analysis of the XMM data is complete. Additional RXTE data were used to determine the underlying continuum of the XMM spectra. A few spectral lines (with low significance) are present in the XMM-Newton data of the Type I bursts of GS 1826-238. In spite of numerous efforts, we cannot identify these lines; perhaps they are not real. The bottom line is that we are unable to determine the gravitational redshift from the surface of the neutron star in GS 1826-238. A gravitational redshift was earlier reported using spectra of Type I bursts observed with XMM-Newton from EX0 0748-676 (Cottam et al., Nature). However, renewed observations by Cottam et al. of EX0 0748-676 with XMM-Newton do not confirm their earlier results. Our adopted Co-I Mario Mendez is presently working on a paper which finalizes our conclusions for GS 1826-238.

New Tactics in Human Rights  

NSDL National Science Digital Library

As this website explains in its Common Questions area, "Tactics consist of how to make a change", and given this statement, the site will be of great interest to those with a concern for international human rights. The New Tactics in Human Rights organization is primarily concerned with providing practitioners in the field with a package of practical tools, a worldwide symposium, and a number of other strategic planning resources. The project itself is coordinated by the Center for Victims of Torture and is overseen by a board of advisors that includes novelist Mario Vargas Llosa and the Right Honorable Kim Campbell, who is the former Prime Minister of Canada. The "Tools for Action" section is a real find as it contains a number of tactical notebooks taken from various case studies around the world, including work from Turkey, Hungary, Romania, and Albania. It is worth noting that many of the materials on the site are also available in Spanish and French.


Regrets after tubal sterilization.  


The tendency to categorize tubal sterilization as an almost trivial procedure may contribute, at least in part, to the fact that a significant minority of women undergo an elective surgical intervention that subsequently they come to regret. These cases may represent a small percentage of the many sterilization operations that are performed each year, yet the fact that tubal sterilization is performed primarily on fit young women for "nonmedical" reasons makes it all the more important that women who will come to regret the procedure are identified and advised against it. It is equally important to remember that such regret after a tubal sterilization will lead increasingly to requests for reversal operations. Sometimes the bases for subsequent regret are almost impossible to predict. It is unrealistic in the extreme to attempt to screen potential candidates for tubal sterilization by asking, "Would you regret this operation if your husband and 3 children were killed in a car crash next month?" Yet, it is possible to anticipate some situations in which subsequent regret may be strong enough to drive a woman to seek sterilization reversal. Abraham et al. have sought differences between 2 groups of women who had either requested a tubal sterilization reversal or else had apparently been satisfied with the procedure. They correctly point out the inherent dangers of interpreting "retrospective data" in 2 basically self-selected groups. Yet, the apparent absence of any longterm followup study of women who have undergone tubal sterilization means that such data provide a valid starting point for debate. Of particular interest is the finding by Abraham et al. that even in their control group 24% of 53 women who had undergone tubal sterilization but not sought a reversal had experienced some regrets at the procedure. The women who sought reversal were more likely at the time of the sterilization operation to have been younger, to have undergone sterilization close to delivery, or to have experienced major life changes after sterilization. 34% of the 32 women in the reversal group did not feel that they had had the major role in the decision to terminate their own reproductive capacity. Abraham et al. conclude that with the development of less traumatic methods of tubal occlusion there is no longer any justification for a hasty decision to sterilize at the time of operative delivery or gynecological surgery, simply to "avoid another operation." The decision to undergo what should still be viewed as a "permanent" loss of reproductive ability requires more leisurely consideration that is afforded during the stresses of childbirth, miscarriage, or abortion.

Slot antenna as a bound charge oscillator.  


We study the scattering properties of an optical slot antenna formed from a narrow rectangular hole in a metal film. We show that slot antennas can be modeled as bound charge oscillators mediating resonant light scattering. A simple closed-form expression for the scattering spectrum of a slot antenna is obtained that reveals the nature of a bound charge oscillator and also the effect of a substrate. We find that the spectral width of scattering resonance is dominated by a radiative damping caused by the Abraham-Lorentz force acting on a bound charge. The bound charge oscillator model provides not only an intuitive physical picture for the scattering of an optical slot antenna but also reasonable numerical agreements with rigorous calculations using the finite-difference time-domain method.

Electric and magnetic fields  

NASA Technical Reports Server (NTRS)

A number of energy momentum anomalies are described that result from the use of Abraham-Lorentz electromagnetic theory. These anomalies have in common the motion of charged bodies or current carrying conductors relative to the observer. The anomalies can be avoided by using the nonflow approach, based on internal energy of the electromagnetic field. The anomalies can also be avoided by using the flow approach, if all contributions to flow work are included. The general objective of this research is a fundamental physical understanding of electric and magnetic fields which, in turn, might promote the development of new concepts in electric space propulsion. The approach taken is to investigate quantum representations of these fields.

Charge Transport Simulations for Amorphous Organic Thin Film Devices  

NASA Astrophysics Data System (ADS)

We employ Monte Carlo simulations to analyze charge transport through amorphous organic thin films using the well-established ``Miller-Abrahams'' hopping model within a disordered manifold of molecular energies. Whereas most existing studies calculate non-dispersive, equilibrium mobilities at low carrier concentrations, in this work we instead calculate current densities for film thicknesses (i.e. 10 to 100 nm) and applied voltages (i.e. 0.1 to 100 V) typical of common thin film devices (e.g. organic light emitting devices and photovoltaics). We find that at these thicknesses one can not assume the non-dispersive, equilibrium condition. Also, since conduction typically occurs at high carrier concentrations and is space charge limited, we must employ simulations which treat both conditions. We compare our results with those predicted by existing analytic theories, and find that the analytic theories are often highly inaccurate, mainly due to faulty use of Fermi statistics and improper calculation of backward hopping.

Limiting partition coefficients of solutes in biphasic trihexyltetradecylphosphonium chloride ionic liquid-supercritical CO2 system: measurement and LSER-based correlation.  


Limiting partition coefficients of a selection of low-to-medium volatility solutes between both phases in a biphasic trihexyltetradecylphosphonium chloride ([thtdp][Cl]) ionic liquid (IL)-supercritical carbon dioxide (scCO2) system were obtained by capillary column chromatography with [thtdp][Cl] as the stationary liquid and scCO2 as the carrier fluid. It is shown that supercritical fluid chromatography can be used to probe the partitioning behavior of solutes in biphasic IL-scCO2 systems even when the IL has nonzero solubility in scCO2. Relative partition coefficients of solutes at a particular temperature and density of CO2 can be correlated within Abraham's linear solvation energy relationships. Compared with our previous results in a [bmim][BF4]-scCO2 system, the solute partition coefficients in the [thtdp][Cl]-scCO2 system are more sensitive to the solute hydrogen bond acidity descriptor.

This site also contains an Abraham Lincoln virtual exhibit and links to other Lincoln sites. Lincoln researchers and enthusiasts should find this site quite interesting.



Digital Image Collections: Indiana Historical Society  

NSDL National Science Digital Library

Bringing together images of African Americans in Indiana, Abraham Lincoln, and many other subjects is an inspired idea, and it's part of the mission of the Indiana Historical Society. Over the past several years, they have been digitizing materials furiously, and currently there are over 38,000 images available on this website. The images are divided into eight topical areas, including "Military History", "Notable Hoosiers", and "African-American Indiana History". The "African-American Indiana History" area is quite fine, and there are images that document the history of the Indianapolis Recorder and Madam C.J. Walker, a self-made businesswoman in the early 20th century. The "Selected Images of Indiana" is also quite laudable, and it also features a subcollection that documents the Hoosier State across the four seasons.

Influence of nonuniform surface magnetic fields in wetting transitions in a confined two-dimensional Ising ferromagnet  

NASA Astrophysics Data System (ADS)

Wetting transitions are studied in the two-dimensional Ising ferromagnet confined between walls where competitive surface fields act. In our finite samples of size L×M, the walls are separated by a distance L, M being the length of the sample. The surface fields are taken to be short-range and nonuniform, i.e., of the form H1,?H1,H1,?H1,..., where the parameter -1???1 allows us to control the nonuniformity of the fields. By performing Monte Carlo simulations we found that those competitive surface fields lead to the occurrence of an interface between magnetic domains of different orientation that runs parallel to the walls. In finite samples, such an interface undergoes a localization-delocalization transition, which is the precursor of a true wetting transition that takes place in the thermodynamic limit. By exactly working out the ground state (T=0), we found that besides the standard nonwet and wet phases, a surface antiferromagnetic-like state emerges for ?<-1/3 and large fields (H1>3), H1tr/J=3, ?tr=-1/3,T=0, being a triple point where three phases coexist. By means of Monte Carlo simulations it is shown that these features of the phase diagram remain at higher temperatures; e.g., we examined in detail the case T=0.7×Tcb. Furthermore, we also recorded phase diagrams for fixed values of ?, i.e., plots of the critical field at the wetting transition (H1w) versus T showing, on the one hand, that the exact results of Abraham [Abraham, Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.44.1165 44, 1165 (1980)] for ?=1 are recovered, and on the other hand, that extrapolations to T?0 are consistent with our exact results. Based on our numerical results we conjectured that the exact result for the phase diagram worked out by Abraham can be extended for the case of nonuniform fields. In fact, by considering a nonuniform surface field of some period ?, with ??M, e.g., [H1(x,?)>0], one can obtain the effective field Heff at a ? coarse-grained level given by Heff=(1)/(?)?x=1?H1(x,?). Then we conjectured that the exact solution for the phase diagram is now given by Heff/J=F(T), where F(T) is a function of the temperature T that straightforwardly follows from Abraham's solution. The conjecture was exhaustively tested by means of computer simulations. Furthermore, it is found that for ??1 the nonwet phase becomes enlarged, at the expense of the wet one, i.e., a phenomenon that we call “surface nonuniformity-induced nonwetting,” similar to the already known case of “roughness-induced nonwetting.”

Libertarianism and circumcision.  


Despite the millenniums-old tradition in Abrahamic circles of removing the foreskin of a penis at birth, the involuntary and aggressive practice of circumcision must not be made an exception to the natural, negative right to self-ownership-a birthright which should prevent a parent from physically harming a child from the moment of birth going forward. This paper will present a natural rights argument against the practice of male child circumcision, while also looking into some of the potential physical and psychological consequences of the practice. It will compare the practice with that of female circumcision, which is banned in developed nations but still practiced in the third world, as well as other forms of aggressive action, some once-prevalent, while disputing arguments made for parental ownership of the child, religious expression, cultural tradition, cleanliness, cosmetics, and conformity.

Illuminating the Decision Path: The Yucca Mountain Site Recommendation  

SciTech Connect

On February 14, 2002, U.S. Secretary of Energy Spencer Abraham provided to the President the ''Recommendation by the Secretary of Energy Regarding the Suitability of the Yucca Mountain Site for a Repository Under the Nuclear Waste Policy Act of 1982.'' This Recommendation, along with supporting materials, complied with statutory requirements for communicating a site recommendation to the President, and it did more: in 49 pages, the Recommendation also spoke directly to the Nation, illuminating the methodology and considerations that led toward the decision to recommend the site. Addressing technical suitability, national interests, and public concerns, the Recommendation helped the public understand the potential risks and benefits of repository development and placed those risks and benefits in a meaningful national context.

Technical basis for polar and nonpolar narcotic chemicals and polycyclic aromatic hydrocarbon criteria. III. A polyparameter model for target lipid partitioning.  


A method is presented for extending the target lipid model (TLM) of narcotic toxicity to polar narcotic chemicals. The proposed polyparameter TLM extends the applicability of the TLM by including polar compounds and removing explicit chemical class corrections. The validity of the model is tested using a data set of 1,687 acute toxicity tests for 42 aquatic species, including fish, amphibians, arthropods, mollusks, polychaetes, coelenterates, protozoans, and algae, and 398 chemicals. The target lipid-water partition coefficient is computed using the Abraham polyparameter model. This replaces use of the octanol-water partition coefficient so that the partitioning of polar narcotic chemicals can be described correctly. The model predicts the log median lethal concentration with a root mean square error of 0.460 for nonpolar and polar chemicals and 0.501 for only polar chemicals. PMID:19245270

Faithful interpreters? Translation theory and practice at the early Royal Society  

PubMed Central

The early Fellows of the Royal Society received letters, papers and printed books written in several European vernaculars. In many cases a translation was needed to make these texts accessible. Translators, though, had to negotiate the Society's corporate views on language and prose style, and also prevailing contemporary theories of literary translation set out by popular poets such as John Dryden and Abraham Cowley. This article examines the translation practices of early Fellows of the Royal Society, showing that translations formed part of a set of knowledge-making processes at meetings. It also discusses the statements about translation theory found in the prefaces to printed volumes produced by or for Royal Society Fellows, arguing that although translators were aware of the requirement for a faithful translation, in fact they often modified their source texts to make them more useful for an English audience.

The Impeachment of Andrew Johnson  

NSDL National Science Digital Library

At the end of the US Civil War, Vice President Andrew Johnson took office as the seventeenth President of the US after Abraham Lincoln's assassination. During Johnson's four-year term as a Democratic President (1865-69), his lenient Reconstruction policies toward the former Confederacy upset the Radical Republicans who controlled Congress. In response to Johnson's highhandedness, the House of Representatives voted articles of impeachment against the President, and he was tried, and subsequently exonerated, before the Senate in 1868. This site explains the key political issues behind Johnson's impeachment, details the legal and political arguments for impeachment, provides biographies and portraits for 28 key figures related to the trial, and chronicles Johnson's term as President. An instructional game that simulates the impeachment process is also included. The majority of content at this site is provided by over 200 excerpts -- including images -- from Harper's Weekly, the most prominent publication of the era.


Monthly stable isotope records in an Australian coral and their correspondence with environmental variables  

NASA Astrophysics Data System (ADS)

Monthly skeletal stable isotope measurements of a Porites australiensis coral from Abraham Reef, Australia, spanning the period from 1981 to 1991, are compared with monthly averaged SST (sea surface temperature) from satellite collected AVHRR (Advanced Very High Resolution Radiometer) and monthly downward surface short-wave insolation (SSI) measurements. We found that the ?18O values varied as a function of the change in seawater temperature. There were anomalously high ?18O values in coral that grew during the summer season of the three El Niño events 1982-83, 1987, and 1991. Advection of seawater with higher salinity (and higher ?18O values) to our site or discrepancies between ocean skin temperature and mixed layer SST are likely reasons for the reduced resolution of ?18O-based SST. Increased coral ?13C values occurred simultaneously with increases in SSI. During most El Niño events the maximum and minimum ?13C values were lower than during normal years.

Polaron effects and electric field dependence of the charge carrier mobility in conjugated polymers  

NASA Astrophysics Data System (ADS)

Charge transport in conjugated polymers has been investigated using Monte Carlo simulations implemented on top of the Marcus theory for donor-acceptor transition rates. In particular, polaron effects and the dependency of the mobility on the temperature and the applied electric field have been studied. The conclusions are that while the qualitative temperature dependence is similar to that predicted by Miller-Abrahams theory in the Gaussian disorder model (GDM), the electric field dependence is characterized by a crossover into the Marcus inverted region, not present in the GDM. Furthermore, available analytical approximations to describe the electric field dependence of the mobility in Marcus theory fail to fit the simulation data and hence cannot be used to directly draw conclusions about the importance of polaron effects for charge transport in conjugated polymers.

Detection of chaos: New approach to atmospheric pollen time-series analysis  

NASA Astrophysics Data System (ADS)

Pollen and spores are biological particles that are ubiquitous to the atmosphere and are pathologically significant, causing plant diseases and inhalant allergies. One of the main objectives of aerobiological surveys is forecasting. Prediction models are required in order to apply aerobiological knowledge to medical or agricultural practice; a necessary condition of these models is not to be chaotic. The existence of chaos is detected through the analysis of a time series. The time series comprises hourly counts of atmospheric pollen grains obtained using a Burkard spore trap from 1987 to 1989 at Mar del Plata. Abraham's method to obtain the correlation dimension was applied. A low and fractal dimension shows chaotic dynamics. The predictability of models for atomspheric pollen forecasting is discussed.

Infrared conductivity in the normal state of cuprate thin films  

SciTech Connect

This paper summarizes the main features of the infrared conductivity spectra in the 500-7000 cm{sup {minus}1} range derived from room-temperature reflectivity measurements performed on a variety of thin films (YBa{sub 2}Cu{sub 3}O{sub 7}, BiSrCaCuO). The conductivity of these samples decreases with frequency as a power law with an exponent {approximately}0.7, and the scattering rate increases linearly with frequency. A detailed comparison with the conductivity for the marginal Fermi liquid (Abrahams, Littlewood, and Varma) and for the Luttinger liquid (Anderson) is performed. In the former case, the effect of temperature appears crucial even in this energy range ({omega}{>=}T) and allows one to achieve satisfactory fits. In the latter case, both the conductivity and the scattering rate may be accounted for by a single parameter.

Unravelling the effects of radiation forces in water.  


The effect of radiation forces at the interface between dielectric materials has been a long-standing debate for over a century. Yet there has been so far only limited experimental verification in complete accordance with the theory. Here we measure the surface deformation at the air-water interface induced by continuous and pulsed laser excitation and match this to rigorous theory of radiation forces. We demonstrate that the experimental results are quantitatively described by the numerical calculations of radiation forces. The Helmholtz force is used for the surface radiation pressure. The resulting surface pressure obtained is consistent with the momentum conservation using the Minkowski momentum density expression assuming that the averaged momentum per photon is given by the Minkowski momentum. Considering the total momentum as a sum of that propagating with the electromagnetic wave and that deposited locally in the material, the Abraham momentum interpretation also appears to be appropriate.

Groups praise, criticize Bush Transition choices  

NASA Astrophysics Data System (ADS)

As the administration of George W. Bush takes hold in the White House, transition plans gradually are coming into focus for many federal agencies that deal with geoscience issues. Congressional confirmation hearings already have been held for cabinet secretary nominees—including Gale Norton, the controversial figure named to head the Department of the Interior. Bush transition team members have fanned out to visit a number of agencies, and interest groups have lined up to either criticize or praise various appointment decisions that affect geoscience issues.Among cabinet nominees, New Jersey Governor Christine Todd Whitman has received mixed reviews as nominee to head the Environmental Protection Agency and is widely viewed as a moderate on environmental issues. Spencer Abraham, nominated to lead the Department of Energy co-sponsored a bill to abolish the department in 1999 while he represented Michigan in the Senate. However, there has not been a groundswell of political energy expended to try to challenge his nomination.

Low-temperature hopping dynamics with energy disorder: renormalization group approach.  


We formulate a real-space renormalization group (RG) approach for efficient numerical analysis of the low-temperature hopping dynamics in energy-disordered lattices. The approach explicitly relies on the time-scale separation of the trapping/escape dynamics. This time-scale separation allows to treat the hopping dynamics as a hierarchical process, RG step being a transformation between the levels of the hierarchy. We apply the proposed RG approach to analyze hopping dynamics in one- and two-dimensional lattices with varying degrees of energy disorder, and find the approach to be accurate at low temperatures and computationally much faster than the brute-force direct diagonalization. Applicability criteria of the proposed approach with respect to the time-scale separation and the maximum number of hierarchy levels are formulated. RG flows of energy distribution and pre-exponential factors of the Miller-Abrahams model are analyzed. PMID:24006985

The value of a p-valueless paper.  


As is common in current biomedical research, about 85% of original contributions in The American Journal of Gastroenterology in 2004 have reported p-values. However, none are reported in this issue's article by Abraham et al. who, instead, rely exclusively on effect size estimates and associated confidence intervals to summarize their findings. Authors using confidence intervals communicate much more information in a clear and efficient manner than those using p-values. This strategy also prevents readers from drawing erroneous conclusions caused by common misunderstandings about p-values. I outline how standard, two-sided confidence intervals can be used to measure whether two treatments differ or test whether they are clinically equivalent. PMID:15330894

Science in the service of patients: lessons from the past in the moral battle for the future of medical education.  


Medical schools instill a classic moral standoff in which the responsibility for the betterment of the patient stands at odds with the responsibility for the betterment of society. In critical ways, the latter, in the form of a robust research and technology-driven enterprise, has taken precedence over the former, resulting in harm to patients and individual dignity. This tradeoff can be traced to Abraham Flexner, the father of American medical education. In the wake of the Flexner report, American medicine set out on a course of exponential scientific advancement, but the mistreatment of research subjects and the erosion of the doctor-patient relationship in a health care system that is increasingly unaffordable, complex, and impersonal suggest that such progress has come at a price. Recent efforts by medical schools to emphasize humanism in their curricula and admissions processes have shown promise in orienting the values of academic medicine toward the individual patient's well-being.

A personal encounter with psychology (1937-2002).  


An undergraduate assistantship with Abraham Maslow, research with Solomon Asch, and an indirect exposure to Ernest Nagel's philosophy of science encouraged Howard H. Kendler to become involved with methodological issues in psychology. Graduate training with Kenneth Spence led to an active research career that was initially immersed in the latent learning controversy and later, with the collaboration of his wife Tracy Kendler, in the extension of the Hull-Spence model of cognitive development. Methodological concerns from a variety of sources encouraged Kendler to express his ideas on the methodology and history of psychology as well as its role in ethical and social policy issues. A productive symbiotic relationship is created from the interaction of democracy, natural-science psychology, and moral pluralism. PMID:11898814

Famous people and genetic disorders: from monarchs to geniuses--a portrait of their genetic illnesses.  


Famous people with genetic disorders have always been a subject of interest because such news feeds the curiosity the public has for celebrities. It gives further insight into their lives and provides a medical basis for any unexplained or idiosyncratic feature or behavior they exhibit. It draws admiration from society of those who excel in their specialized fields despite the impositions of their genetic illnesses and also elicits sympathy even in the most casual observer. Such news certainly catapults a rare genetic disorder into the realm of public awareness. We hereby present six famous figures: King George III, Toulouse-Lautrec, Queen Victoria, Nicolo Paganini, Abraham Lincoln, and Vincent van Gogh, all of whom made a huge indelible mark in either the history of politics or that of the arts.

The site notes that it "takes the stories behind our community-driven historical markers, adds related items from the Kentucky Historical Society and combines it into a historical tour of our Commonwealth." The historical markers are crafted by the Society and placed around the state in locations that include the Samuel May House and Abraham Lincoln's boyhood home in Knob Creek. Additionally, the site includes thematic tours of Danville, the University of Kentucky, and the War of 1812. Finally the Stories area allows visitors to browse through an alphabetical list of all the markers from the Zachary Taylor National Cemetery to the Battle of Augusta.


Spinocerebellar ataxia type 5 in a family descended from the grandparents of President Lincoln maps to chromosome 11.  


Autosomal dominant ataxias are a genetically heterogeneous group of disorders for which spinocerebellar ataxia (SCA) loci on chromosomes 6p, 12q, 14q and 16q have been reported. We have examined 170 individuals (56 of whom were affected) from a previously unreported ten-generation kindred with a dominant ataxia that is clinically and genetically distinct from those previously mapped. The family has two major branches which both descend from the paternal grandparents of President Abraham Lincoln. Among those examined, 56 individuals have a generally non-life threatening cerebellar ataxia. Disease onset varies from 10-68 years and anticipation is evident. We have mapped this gene, spinocerebellar ataxia type 5 (SCA5), to the centromeric region of chromosome 11. PMID:7874171

Masking of low frequency information in short-range apparent motion.  


When an array of random dots is displaced, the ability to report the direction of apparent motion is subject to an upper spatial limit (dmax). Using spatially low-pass filtered random dot kinematograms we show that dmax is dependent on the upper cut-off frequency of the stimulus (Fh). The extent of this dependence is critically dependent on the size of the stimulus. Our results suggest a process whereby low spatial frequency motion information is masked by the presence of high spatial frequencies in the same region of the field, analogous to phenomena occurring in the perception of static form (e.g. the Abraham Lincoln effect). The effects of stimulus size on dmax, found for broad-band stimuli by ourselves and others, result from a loss of high frequency sensitivity at increased retinal eccentricities; this loss reduces the masking effect of high frequencies, as stimulus size increases.

Virginia Convention of 1861  

NSDL National Science Digital Library

On a fateful day in February 1861, delegates from all of Virginia's counties met to decide how the state would respond to a number of recent events, including Abraham Lincoln's election and South Carolina's secession. Ultimately, they voted to remain in the Union, as there was still hope at that moment that a compromise would be forthcoming. Two months later all of this changed, as the same delegates moved to secede from the United States. This remarkable website from the University of Richmond contains the fully transcribed text of these debates, along with interactive maps, information about the delegates, and a brief primer on the convention. Visitors can use the tools on the right-hand side of the homepage to get started, or they can also use the "Suggested Searches" area to search for words like "war" and "slave". Also, visitors should not miss the "Data Visualizations", which include a timeline and a graphic representation of the votes for secession by county.


The differing views on insanity of two nineteenth century forensic psychiatrists.  


Dr. Charles H. Nichols and Dr. John P. Gray were the two foremost forensic psychiatrists in the latter half of the nineteenth century in the U.S. However, their rationales differed dramatically. They were involved in four notable murder trials where insanity issues arose: one was a trial for the murderer of a Union officer during the Civil War; in another, a conspirator was tried for the assassination of President Abraham Lincoln; in the third, a temporary insanity plea was supported by a medical expert for the first time in a U.S. courtroom; and the fourth was the trial of the assassin of President James A. Garfield. Pointedly, their differing viewpoints still remain controversial today. PMID:17094649

A house divided cannot stand  

SciTech Connect

When it comes to the relationships between electric utilities and public service commissions, utilities would do well to remember the words of Abraham Lincoln -- [open quotes]A house divided against itself cannot stand.[close quotes] For just as distrust, dissension, and division threatened the future of the United States during the Civil War, they threaten the future of utilities today.In an effort to lower their costs and increase their competitive advantage, utility companies are increasingly looking to reinvent cultures, reengineer work processes, and redefine corporate missions, values, and strategies. But unless utilities also rebuild regulatory relations, such efforts are doomed to fail. If this prognosis sounds overly simplistic or melodramatic -- especially as utilities appear to be moving toward an era of reduced regulation -- think again. History shows that regulatory relationships drive a utility's ability to successfully integrate demand-side management (DSM) programs that are often critical to business strategies and goals.

A. Lincoln, esquire defends the murderer of a physician.  


After only about a year of law practice, Abraham Lincoln participated in his first murder trial. Dr. Jacob M. Early was shot and killed in a bitter political imbroglio. Lincoln joined a defense team of highly accomplished litigators. Despite his having the least legal experience, he was selected to give the defense summation. In his argument, he spoke to the jury in a conversational tone making his point that Dr. Early had a deadly weapon in his hands, namely an upraised wooden chair, when he was shot. His self-defense plea indicated that Henry B. Truett, the defendant, truly believed that he was in danger of being crushed by the upraised chair. Interestingly, Lincoln knew both the defendant and the murdered physician. He handled litigation for the former and served in the Black Hawk War under the command of the latter. Furthermore Lincoln knew at least five of the jurors. PMID:15989212

Comprehensive reimbursement model: an alternative to fee-for-service reimbursement by blood centers.  


"If we could first know where we are, and whither we are tending, we could then better judge what to do and how to do it." This quote from Abraham Lincoln epitomizes where SMF and its CRM hospital customers are today. The CRM has been received by SMF's hospital customers as a step in the right direction. Currently, it seems to be the best way to partner with hospitals by sharing risk in the current health care delivery system milieu. The CRM focus on patient outcomes will provide hospitals and blood centers a common goal. Modifications to the CRM will most certainly be necessary. With input from customers and the community over time, and flexibility from SMF, a revised model will evolve that will be even more mutually beneficial. PMID:9031489

Alcohol and the heart: to abstain or not to abstain?  


Alcohol has been consumed by most societies over the last 7000 years. Abraham Lincoln said "It has long been recognized that the problems with alcohol relate not to the use of a bad thing, but to the abuse of a good thing." Light to moderate alcohol consumption reduces the incidence of coronary heart disease (CHD), ischemic stroke, peripheral arterial disease, CHD mortality, and all-cause mortality, especially in the western populations. However, heavy alcohol consumption is detrimental causing cardiomyopathy, cardiac arrhythmias, hepatic cirrhosis, pancreatitis, and hemorrhagic stroke. In this article, we review the effects of alcohol on CHD, individual cardiovascular risk factors, cardiomyopathy, and cardiac arrhythmias, including the most recent evidence of the effects of alcohol on CHD.

The structural, electronic and optical properties of the CuGa (Se x S1- x )2 alloy system have been performed systematic within generalized gradient approximation (GGA) of Perdew-Burke-Ernzerhof (PBE) implemented in the Cambridge serial total energy package (CASTEP) code. We calculate the lattice parameters and axial ratio, which agree with the experimental values quite well. The anion position parameters u are also predicted using the model of Abrahams and Bernstein and the results seem to be trustworthy as compared to the experimental and theoretical values. The total and part density of states are discussed which follow the common rule of the conventional semiconductors. The static dielectric tenser and refractive index are summarized compared with available experimental and theoretical values. Also the spectra of the dielectric functions, refractive index, reflectance, absorption coefficient and real parts of photoconductivity are discussed in details.

An analysis of skeletal remains from cemeteries at the ancient cities of Ur and Kish (circa 2000 B.C.), show a genetically homogeneous, diseased, and short-lived population. These ancient Mesopotamians suffered severe dental attrition (95 percent), periodontal disease (42 percent), and caries (2 percent). Many oral congenital and neoplastic lesions were noted. During this period, the "local dentists" knew only a few modern dental techniques. Skeletal (dental) evidence indicates that the population suffered from chronic malnutrition. Malnutrition was probably caused by famine, which is substantiated in historic cuneiform and biblical writings, geologic strata samples, and analysis of skeletal and forensic dental pathology. These people had modern dentition but relatively poor dental health. The population's lack of malocclusions, caries, and TMJ problems appear to be due to flat plane occlusion. PMID:11324038

Gerotrancscendence through Jewish eyes.  


The Swedish sociologist Tornstam perceives old age as the peak of human maturation whose favorable culmination is gerotranscendence. The latter is characterized by breaking out of one's finite existence and uniting with a greater world with respect to past, present, and future. Tornstam relates to gerotranscendent roots in Eastern cultures; this study will examine how gerotranscendence finds expression in Jewish sources. Varied Jewish texts speak to how the wisdom that accrues from life experience enables one to rise above physical decline and enrich relationships via self, fellow man, and cosmos. Three major biblical exemplars of gerotranscendors are depicted: Abraham, focusing on limitless giving to fellow man; Isaac, overcoming psychological barriers of past paternal disappointments; and Jacob uniting with his children and grandchildren through the blessing that becomes a legacy for perpetuating the future of the nation. Practical applications of the study for more meaningful aging are discussed. PMID:22434577

Quantitative structure carcinogenicity relationship for detecting structural alerts in nitroso-compounds: species: rat; sex: male; route of administration: water.  


In this work, Quantitative Structure-Activity Relationship (QSAR) modelling was used as a tool for predicting the carcinogenic potency of a set of 39 nitroso-compounds, which have been bioassayed in male rats by using the oral route of administration. The optimum QSAR model provided evidence of good fit and performance of predicitivity from training set. It was able to account for about 84% of the variance in the experimental activity and exhibited high values of the determination coefficients of cross validations, leave one out and bootstrapping (q(2)(LOO)=78.53 and q(2)(Boot)=74.97). Such a model was based on spectral moments weighted with Gasteiger-Marsilli atomic charges, polarizability and hydrophobicity, as well as with Abraham indexes, specifically the summation solute hydrogen bond basicity and the combined dipolarity/polarizability. This is the first study to have explored the possibility of combining Abraham solute descriptors with spectral moments. A reasonable interpretation of these molecular descriptors from a toxicological point of view was achieved by means of taking into account bond contributions. The set of relationships so derived revealed the importance of the length of the alkyl chains for determining carcinogenic potential of the chemicals analysed, and were able to explain the difference between mono-substituted and di-substituted nitrosoureas as well as to discriminate between isomeric structures with hydroxyl-alkyl and alkyl substituents in different positions. Moreover, they allowed the recognition of structural alerts in classical structures of two potent nitrosamines, consistent with their biotransformation. These results indicate that this new approach has the potential for improving carcinogenicity predictions based on the identification of structural alerts. PMID:18533217

Spin behavior near the metal-insulator transition in Si MOSFETs  

NASA Astrophysics Data System (ADS)

When a perpendicular magnetic field is applied to a two-dimensional electron system, extended (delocalized) states exist in the middle of the quantized Landau levels which allow conduction at zero temperature. In the absence of a magnetic field, however, noninteracting electrons are always localized [1]. The fate of the finite-field extended states as the magnetic field approaches zero has been a subject of debate for almost 20 years. The prevailing view holds that the energy of these extended states increases to infinity as the field approaches zero, giving rise to an insulator [2-5]. However, the situation is different in strongly interacting electron systems where metallic conductivity has been recently discovered in zero magnetic field [6]. In such systems, the energy of the extended states remains finite, thus allowing conduction in the limit of zero temperature at B=0 [7]. Here we show that aligning the electrons' spins causes the extended states to once more increase in energy in the vanishing perpendicular magnetic field, as they do for non-interacting electrons. The difference between extended states that increase in energy (an insulator) or remain finite (a metal) is thus unambiguously tied to the existence of the spins. [1] E. Abrahams, P. W. Anderson, D.

Motivation: a new look at an age-old topic.  


Employee motivation is a shared responsibility. An employee has to have some amount of intrinsic desire to perform a task. You can't create that desire. But, you can create an environment that brings out that desire, and allows an employee to shine. Abraham Maslow developed one of the most useful of all motivation theories--the "Hierarchy of Needs"--in the 1940s, and it is still the prevailing theory today. The Needs Hierarchy begins with the basic idea that only an unfulfilled need is a motivator. Or, in plain English, people perform specific actions to meet specific personal needs. Maslow defines five levels of needs that all people experience: 1: Physiological, Food, shelter, and yes, sex. 2: Safety/Security. No personal harm and the current lifestyle is safe. 3: Social. The need for acceptance by others, for belonging, friendship and affection. 4: Self-Esteem/Ego. Recognition, status and prestige. 5: Self-Actualization. Self-fulfillment and the need for achieving one's personal best. What makes this needs theory so interesting and so useful in the workplace is the clarity with which a position in the hierarchy can be determined. The basic premise is that lower-level needs must be satisfied before moving upward to the next level. Consider your own employees and what you know about them. Look at their situations, and evaluate where they may be in the hierarchy. Remember, it's difficult to separate their personal situations from their work personas. Try using Abraham Maslow as a starting point to identify motivations of your staff. PMID:14603593

Critical study and discrimination of different formulations of electromagnetic force density and consequent stress tensors inside matter  

NASA Astrophysics Data System (ADS)

By examination of the exerted electromagnetic (EM) force on boundary of an object in a few examples, we look into the compatibility of the stress tensors corresponding to different formulas of the EM force density with special relativity. Ampere-Lorentz's formula of the EM force density is physically justifiable in that the electric field and the magnetic flux density act on the densities of the total charges and the total currents, unlike Minkowski's formula which completely excludes the densities of the bounded charges and the bounded currents inside homogeneous media. Abraham's formula is fanciful and devoid of physical meaning. Einstein-Laub's formula seems to include the densities of the total charges and the total currents at first sight, but grouping the bounded charges and the bounded currents into pointlike dipoles erroneously results in the hidden momentum being omitted, hence the error in [Phys. Rev. Lett. 108, 193901 (2012), 10.1103/PhysRevLett.108.193901]. Naturally, the Ampere-Lorentz stress tensor accords with special relativity. The Minkowski sress tensor is also consistent with special relativity. It is worth noting that the mathematical expression of the Minkowski stress tensor can be quite different from the well-known form of this stress tensor in the literature. We show that the Einstein-Laub stress tensor is incompatible with special relativity, and therefore we rebut the Einstein-Laub force density. Since the Abraham momentum density of the EM fields is inherently corresponding to the Einstein-Laub force density [Phys. Rev. Lett. 111, 043602 (2013), 10.1103/PhysRevLett.111.043602], our rebuttal may also shed light on the controversy over the momentum of light.

F. Sherwood “Sherry” Rowland (1927-2012)  

NASA Astrophysics Data System (ADS)

Frank Sherwood Rowland, known to his friends and colleagues as Sherry, died at his home in Corona del Mar, Calif., on 10 March 2012. He was 84. A Nobel Prize-winning atmospheric chemist, Sherry codiscovered the role of chlorofluorocarbons (CFCs) in stratospheric ozone depletion, researched the accumulation of greenhouse gases on a planetary scale, and tirelessly communicated the global consequences of human activity to policy makers and the public. Sherry had a calm, gentle demeanor and was as respected for his integrity and humility as for his groundbreaking scientific achievements. Sherry was a long-time member and Fellow (1980) of AGU and received the AGU Roger Revelle Medal in 1994 for his substantial contributions to the awareness of global change. The following year, he shared the Nobel Prize in Chemistry with Mario Molina and Paul Crutzen for their pioneering contributions to atmospheric chemistry, particularly the formation and decomposition of stratospheric ozone. In its citation, the Nobel Committee commended them for contributing to “our salvation from a global environmental problem that could have catastrophic consequences.”

Analytical Sociology: A Bungean Appreciation  

NASA Astrophysics Data System (ADS)

Analytical sociology, an intellectual project that has garnered considerable attention across a variety of disciplines in recent years, aims to explain complex social processes by dissecting them, accentuating their most important constituent parts, and constructing appropriate models to understand the emergence of what is observed. To achieve this goal, analytical sociologists demonstrate an unequivocal focus on the mechanism-based explanation grounded in action theory. In this article I attempt a critical appreciation of analytical sociology from the perspective of Mario Bunge's philosophical system, which I characterize as emergentist systemism. I submit that while the principles of analytical sociology and those of Bunge's approach share a lot in common, the latter brings to the fore the ontological status and explanatory importance of supra-individual actors (as concrete systems endowed with emergent causal powers) and macro-social mechanisms (as processes unfolding in and among social systems), and therefore it does not stipulate that every causal explanation of social facts has to include explicit references to individual-level actors and mechanisms. In this sense, Bunge's approach provides a reasonable middle course between the Scylla of sociological reification and the Charybdis of ontological individualism, and thus serves as an antidote to the untenable "strong program of microfoundations" to which some analytical sociologists are committed.

LiDAR in extreme environment: surveying in Antarctica  

NASA Astrophysics Data System (ADS)

This study was performed under the patronage of the Italian National Research Programme in Antarctica (PNRA) with the aim to realize a high resolution Digital Elevation Model (DEM) of the moraine named "Boulder Clay" which insists approximately 7 km far from the Italian Research Base "Mario Zucchelli Station" in the Terra Nova Bay area. The DEM will be included in the project for the construction of two runways to be used as support facilities for the scientific research campaigns which take place on regular basis each year. Although the research efforts to realize a detailed cartography of the area is on-going, for the specific aim and urgency of this project it was decided to perform a laser scanning survey in this extreme environment in order to obtain contour lines describing the terrain elevation each 50 cm and volume analysis. The final result will be super imposed on a photogrammetric DEM with contour lines each 2.5 m and satellite images. This paper focus both on the final scientific data and on all the challenges have to be faced in such extreme and particular environment during the laser scanning survey.

Gauguin Tahiti  

NSDL National Science Digital Library

Despite living most of his life in France, Paul Gauguin is immediately identified with Tahiti, largely due to his immense body of visual art (such as paintings and sculptures) that were produced during his time there during the turn of the 19th century. One of these monumental works is an impressive canvas titled, Where Do We Come From? What Are We? Where Are We Going? At the time of its completion, Gauguin noted that "I believe that this canvas not only surpasses all my preceding ones, but that I shall never do anything better, or even like it." This extraordinary work forms the centerpiece of a current exhibition at the Museum of Fine Arts in Boston, and is extensively profiled on this website for the web-browsing public. From this site, visitors can view in great detail an interactive presentation of this work, presented by Visitors may move a virtual magnifying glass over the work and click on fifteen separate areas that profile various segments of the painting. Each clickable fragment is further augmented by audio interviews from art historians offering their learned commentaries. Additionally, visitors can listen to an interview with exhibition curator George Shackelford, Mario Vargas Llosa, and Elizabeth Childs, professor of art history at Washington University in St. Louis.


Do the Modern Neurosciences Call for a New Model of Organizational Cognition?  

NASA Astrophysics Data System (ADS)

Our purpose in this paper is to try to make a significant contribution to the analysis of cognitive capabilities of the organization of active social systems such as the business enterprise by re-examining the concepts of organizational intelligence, organizational memory and organizational learning in light of the findings of modern neuroscience. In fact, in this paper we propose that neuroscience shows that sociocognitivity is for real. In other words, cognition, in the broad sense, is not exclusive to living organisms: Certain kinds of social organizations (e.g. the enterprise) possess elementary cognitive capabilities by virtue of their structure and their functions. The classical theory of organizational cognition is the theory of Artificial Intelligence. We submit that this approach has proven to be false and barren, and that a materialist emergentist neuroscientific approach, in the tradition of Mario Bunge (2003, 2006), leads to a far more fruitful viewpoint, both for theory development and for eventual factual verification. Our proposals for sociocognitivity are based on findings in three areas of modern neuroscience and biopsychology: (1) The theory of intelligence and of intelligent systems; (2) The neurological theory of memory as distributed, hierarchical neuronal systems; (3) The theory of cognitive action in general and of learning in particular. We submit that findings in every one of these areas are applicable to the social organization.

Individual differences in motives, preferences, and pathology in video games: the gaming attitudes, motives, and experiences scales (GAMES).  


A new measure of individual habits and preferences in video game use is developed in order to better study the risk factors of pathological game use (i.e., excessively frequent or prolonged use, sometimes called "game addiction"). This measure was distributed to internet message boards for game enthusiasts and to college undergraduates. An exploratory factor analysis identified 9 factors: Story, Violent Catharsis, Violent Reward, Social Interaction, Escapism, Loss-Sensitivity, Customization, Grinding, and Autonomy. These factors demonstrated excellent fit in a subsequent confirmatory factor analysis, and, importantly, were found to reliably discriminate between inter-individual game preferences (e.g., Super Mario Brothers as compared to Call of Duty). Moreover, three factors were significantly related to pathological game use: the use of games to escape daily life, the use of games as a social outlet, and positive attitudes toward the steady accumulation of in-game rewards. The current research identifies individual preferences and motives relevant to understanding video game players' evaluations of different games and risk factors for pathological video game use.

DASMI: exchanging, annotating and assessing molecular interaction data  

PubMed Central

Motivation: Ever increasing amounts of biological interaction data are being accumulated worldwide, but they are currently not readily accessible to the biologist at a single site. New techniques are required for retrieving, sharing and presenting data spread over the Internet. Results: We introduce the DASMI system for the dynamic exchange, annotation and assessment of molecular interaction data. DASMI is based on the widely used Distributed Annotation System (DAS) and consists of a data exchange specification, web servers for providing the interaction data and clients for data integration and visualization. The decentralized architecture of DASMI affords the online retrieval of the most recent data from distributed sources and databases. DASMI can also be extended easily by adding new data sources and clients. We describe all DASMI components and demonstrate their use for protein and domain interactions. Availability: The DASMI tools are available at and The DAS registry and the DAS 1.53E specification is found at Contact: Supplementary information: Supplementary data and all figures in color are available at Bioinformatics online.

Quantum transport and nanoplasmonics with carbon nanorings - using HPC in computational nanoscience  

NASA Astrophysics Data System (ADS)

Central theme of this talk is the theoretical study of toroidal carbon nanostructures as a new form of metamaterial. The interference of ring-generated electromagnetic radiation in a regular array of nanorings driven by an incoming polarized wave front may lead to fascinating new optoelectronics applications. The tight-binding method is used to model charge transport in a carbon nanotorus: All transport observables can be derived from the Green's function of the device region in a non-equilibrium Green's function algorithm. We have calculated density-of-states D(E) and transmissivities T(E) between two metallic leads under a small voltage bias. Electron-phonon coupling is included for low-energy phonon modes of armchair and zigzag nanorings with atomic displacements determined by a collaborator's finite-element based code. A numerically fast and stable algorithm has been developed via parallel linear algebra matrix routines (PETSc) with MPI parallelism to reach significant speed-up. Production runs are planned on the NSF XSEDE network. This project was supported in parts by a 2010 NSF TeraGrid Fellowship and the Sunshine State Education and Research Computing Alliance (SSERCA). Two summer students were supported as 2010 and 2011 NCSI/Shodor Petascale Computing undergraduate interns.[4pt] In collaboration with Leon W. Durivage, Adam Byrd, and Mario Encinosa.

Relational responding by eastern box turtles (Terrapene carolina) in a series of color discrimination tasks.  


Prior work with chelonians has demonstrated their capacity for successful performance in cognitive tasks, including those requiring color discrimination. Here, we sought to expand on historical research and determine whether eastern box turtles (Terrapene carolina) are capable of not only making simple color discriminations but also whether they can demonstrate abstract concept formation evidenced by using a relational response rule in their discrimination performance. Two eastern box turtles were rapidly and successfully trained on a black-and-white two-choice discrimination task using painted paddles and food reinforcement. After mastery, a medium gray paddle was added as a choice stimulus and turtle "Flippy" was reinforced for selecting the darker of the 2 stimuli presented in each trial, and turtle "Mario" was reinforced for selecting the lighter of the paddles presented. Nonreinforced probe trials incorporating light and dark gray stimuli paired with all other color options were then added to each session to test the turtles' ability to use the relationship between choice stimuli to guide responding. The turtles successfully selected the paddles corresponding to their assigned relational response rule of "darker" or "lighter" at a level significantly above that predicted by chance. The turtles then demonstrated immediate generalization of their relational rule in testing with a novel array of blue paddles. Finally, the turtles continued to use their relational rule when presented with a novel array of green paddles in a traditional transposition task. Together, these findings support the capacity for higher order cognitive functioning in chelonians beyond that previously described. PMID:23339559

Calculations of relative optical air masses for various aerosol types and minor gases in Arctic and Antarctic atmospheres  

NASA Astrophysics Data System (ADS)

dependence functions of relative optical air mass on apparent solar zenith angle ? have been calculated over the ? < 87° range for the vertical profiles of wet-air molecular number density in the Arctic and Antarctic atmospheres, extinction coefficients of different aerosol types, and molecular number density of water vapor, ozone, nitrogen dioxide, and oxygen dimer. The calculations were made using as weight functions the seasonal average vertical profiles of (i) pressure and temperature derived from multiyear sets of radiosounding measurements performed at Ny-Ålesund, Alert, Mario Zucchelli, and Neumayer stations; (ii) volume extinction coefficients of background summer aerosol, Arctic haze, and Kasatochi and Pinatubo volcanic aerosol measured with lidars or balloon-borne samplings; and (iii) molecular number concentrations of the above minor gases, derived from radiosonde, ozonesonde, and satellite-based observations. The air mass values were determined using a formula based on a realistic atmospheric air-refraction model. They were systematically checked by comparing their mutual differences with the uncertainties arising from the seasonal and daily variations in pressure and temperature conditions within the various ranges, where aerosol and gases attenuate the solar radiation most efficiently. The results provide evidence that secant-approximated and midlatitude air mass values are inappropriate for analyzing the Sun photometer measurements performed at polar sites. They indicate that the present evaluations can be reliably used to estimate the aerosol optical depth from the Arctic and Antarctic measurements of total optical depth, after appropriate corrections for the Rayleigh scattering and gaseous absorption optical depths.

Old italian reference systems and their applications  

NASA Astrophysics Data System (ADS)

The history of geodetic systems used in Italy from the end of the XIX century to the beginning of the XXth century is complex and, in the past, this has led some researcher to misinterpretations. For this reason an explanation of geodetic systems used in Italy in this period is reported in this paper. Towards the end of the XIXth century, the " Ufficio Tecnico del Corpo di Stato Maggiore" (first nucleus of the future IGM) was entrusted to unify the geodetic reference systems of the Italian pre-union states to produce a unique Italian Datum for the whole national territory. At the same time, the "Ufficio del Catasto" (National Cadastre Office), for its purposes, began the production of a cartography in projection Cassini-Soldner representing only the thematic layer of its interest: the delimitations of properties. Although officially the Datums used in those years are the same both for cadastre and IGM (Genoa, Monte Mario, Castanea delle Furie), in many cases temporary orientations were used on cadastral maps and the values of first, second and third order vertexes do not coincide with those definitive ones used by the IGM. This ambiguity led frequently to misinterpretation and errors to georeferenciation of present and historic Italian cartography

The IDE Virtual Design Museum  

NSDL National Science Digital Library

Many of the common objects in our everyday world (such as kitchen timers, telephones, and answering machines), seem to go unnoticed until someone wonders out loud: "I wonder who designed that?" Fortunately, the good people at the Delft University of TechnologyâÂÂs Faculty of Industrial Design have created this virtual design museum to answer that exact question, and to take visitors on a tour of some intriguing designs created by European and American designers over the past decades. Visitors are free to browse through the Famous Designers section which features the work of such icons as Raymond Loewy, Ferdinand Porsche, and Mario Bellini. Each entry includes a selection of images of some of the most celebrated designs, and in several cases a short biographical sketch is available. Visitors may also elect to look through the Famous Companies area, which brings together work by such companies as Bang & Olufsen, Braun, Grundig, and IBM. Those with only a few minutes will want to peruse such objects as Dieter Ramsâ design for a table top cigarette lighter for the Braun Company in 1970 and Aldo RossiâÂÂs 1995 coffee pot from the table service "il Faro."


A quantitative study of peculiarities in galaxy morphology  

NASA Astrophysics Data System (ADS)

I have developed a refined version of the asymmetry parameter first presented by Abraham et al. (1996). Coupled with a simple concentration index, this pair of indices, AW-CW, is compared to Abraham et al.'s log(AA)-log(C A) algorithm. These indices are then applied to a large sample of galaxies in the Hubble Deep Field with photometric redshifts from Connolly (1999). This allows investigation of trends at redshifts which have been largely inaccessible until now. The final sample consists of ~350 objects detected by the AW-CW algorithms with first-moment radii, r1 >= 0'.2 (corresponding to F814WAB ~ 26). The distribution of objects in the AW- CW plane is found to change with redshift. The region of the AW - CW plane populated by objects out to z ~ 1.2 is roughly constant. Accounting for bandpass shifting effects, this region resembles that populated by local bright galaxies (Frei et al. 1996) cosmologically simulated at z = 0.8. Beyond z ~ 1.2, the distribution of galaxies undergoes a significant change. Highly concentrated objects disappear from the AW-C W plane, while high asymmetry objects appear. The high concentration objects below z ~ 1.2 all have early-type morphologies. Very low resolution SEDs of these galaxies created using colors from Williams et al. (1996) are used to calculate the expected appearance of these objects at higher redshifts (z = 1.5 and 2.3). Assuming their luminosities and SEDs have not changed, one-third of the z ~ 0.8 objects would be undetected at z = 1.5, and 97% would disappear by z = 2.3. Any true drop in the number density of these objects would be completely masked by such strong selection effects. An increase in the number and degree of asymmetric objects is also seen beyond z ~ 1.2. Many of these objects exhibit multiple condensations, consistent with merging. Though the shifting of the ultraviolet galaxy spectrum into the F814W-band may be partially responsible, the majority of the increase in both number and degree of asymmetry appears to reflect a genuinely higher number density of asymmetric objects at earlier epochs. AW and CW are shown to be useful tools for exploring galaxy morphology over a wide range of redshifts. Future refinements combined with better SEDs and evolutionary models will undoubtedly reveal valuable insight into galaxy evolution.

Electromagnetic Radiation Reaction in General Relativity.  

NASA Astrophysics Data System (ADS)

Available from UMI in association with The British Library. This thesis examines the electromagnetic radiation reaction felt by a charged body falling freely in an external gravitational field in general relativity. The original objective was to find a new derivation of the radiation reaction force F^{i} of DeWitt and DeWitt^1 which was calculated for the special case of a point charge falling in slow motion in a weak, static gravitational field: F ^{i} = {2over 3}e^2R^{i}_{0j0 }v^{j}. This may be thought of as a local expression since it involves the particle's velocity v^{j } and the local Riemann curvature tensor R ^{i}_{0j0}. Its derivation involves integrals over the whole history of the particle, covering distances of approximately the length scale on which R^{i}_{0j0 } changes. This is different from calculations of the Abraham-Lorentz force of flat space-time involving integrals over distances only a few times the size of the charge. This work was motivated by the wish to find a "local" derivation of the local reaction force. Using Schutz's^2 local initial value method to solve the problem of a charged, rigid, spherically symmetric body moving in an external gravitational field of arbitrary metric. Calculations are done in a Riemann normal coordinate system ^3 and are only valid in a normal neighbourhood of the origin, where geodesics have not begun to cross one another. We solve Maxwell's equations for the self -force by making a slow-motion approximation and keeping terms to first order only in the Riemann tensor and velocity. It is surprising that we find no local radiation reaction. Consider two particles in a static spacetime with the same initial conditions at t = 0. Particle A is that of DeWitt and DeWitt; it feels a reaction force F^{i} = {2over 3}e^2R^{i }_{0j0}v^{j}. Particle B is accelerated from rest to the same small velocity; it feels no reaction force. The two particles therefore follow different trajectories. We conclude that there is a certain amount of history dependence in curved spacetime which is absent in flat spacetime where the Abraham-Lorentz reaction force acts equally on both particles. ftn ^1C.

Managers and leaders: are they different?  


The traditional view of management, back in 1977 when Abraham Zaleznik wrote this article, centered on organizational structure and processes. Managerial development at the time focused exclusively on building competence, control, and the appropriate balance of power. That view, Zaleznik argued, omitted the essential leadership elements of inspiration, vision, and human passion which drive corporate success. The difference between managers and leaders, he wrote, lies in the conceptions they hold, deep in their psyches, of chaos and order. Managers embrace process, seek stability and control, and instinctively try to resolve problems quickly--sometimes before they fully understand a problems significance. Leaders, in contrast, tolerate chaos and lack of structure and are willing to delay closure to understand the issues more fully. In this way, Zaleznik argued, business leaders have much more in common with artists, scientists, and other creative thinkers than they do with managers. Organizations need both managers and leaders to succeed, but developing both requires a reduced focus on logic and strategic exercises in favor of an environment where creativity and imagination are permitted to flourish.

Properties of Bars in the Local Universe  

NASA Astrophysics Data System (ADS)

Early work on bar fractions suffered from poor sample sizes which limited the study of correlations between bar fraction and physical properties. Recent large surveys like SDSS and COSMOS have helped rectify this deficiency. Sheth et al. (2008) using a sample of 2000 galaxies from COSMOS, have shown that bar fractions decrease with redshift as claimed by Abraham et al. (1999) and van den Bergh et al. (2000) . In addition, they find the bar fraction of spiral galaxies is a strong function of stellar mass, color and bulge prominence such that more massive, redder, concentrated galaxies have a larger bar fraction than less massive, bluer, diskier galaxies. Barazza et al. (2008) using 2000 galaxies from SDSS find results counter to Sheth et al. (2008) i.e., bar fractions increase with decreasing mass and bluer colors (corresponding to late type galaxies). Using a larger sample of 15000 visually classified SDSS galaxies (which includes bar classifications) I further investigate the properties of barred galaxies in the local universe. In addition, I will describe the variation of total fine fraction (bars + rings +lenses) with physical properties and the effects of AGN on the observed fine fraction.

A fatal outcome in a patient with glioblastoma multiforme after receiving high-dose methotrexate.  


The most common adult primary brain tumor is glioblastoma multiforme (GBM). Current treatment is surgical resection, adjuvant radiation and chemotherapy, which can extend the median survival 20-36 weeks (Mansky et al. Central nervous system tumors. In Abraham J, Allegra CJ, Gulley J, eds. Bethesda Handbook of clinical oncology, 2nd edn. Philadelphia, Pennsylvania: Lippincott Williams and Wilkins, 2000: 440-2; Knox S. Intracranial tumors. In Pillot G, Chantler M, Magiera H, Peles S, et al., eds. The Washington Manual Hematology and Oncology Subspecialty Consult. Philadelphia, Pennsylvania: Lippincott Williams and Wilkins, 2004: 204-6.). But treatment efficacy is limited, mandating the exploration of more effective treatments. We report on a patient with GBM treated as per a clinical protocol with high-dose methotrexate (12 g/m(2)), who expired within hours after the initiation of treatment secondary to transtentorial herniation. Although it is not completely clear what caused the patient's herniation, we think that high-dose methotrexate therapy may have played a crucial role. We suggest that high-dose methotrexate should be used cautiously in patients with GBM. PMID:18337442

The twice-born personality. Interview by Joe Flower.  


Abraham Zaleznik focuses on some things that might seem old-fashioned: talent, the individual mind, and a fascination with the content, the product, the nuts and bolts of the business. He is the great champion of the individual in corporate life. There has been a lot of discussion about the difference between managers and leaders. It was Zaleznik who started the discussion some 15 years ago in a seminal Harvard Business Review article called "Managers and Leaders: Are They Different?" A lot of his colleagues at Harvard, prime developers of the profession of management, thought he was nuts. He argued that management and leadership involve completely different mindsets, and that great business enterprises suffer when they are given over to professional managers. His ideas strike sparks against those of other people we have interviewed in this series. He questions the value of the total quality movement, and the importance of teamwork. Where Russell Ackoff spoke of democracy and free markets within the corporation, Zaleznik praises hierarchy. Where Terry Deal found cohesion and motivation in the meanings and rituals of the workplace, Zaleznik dismisses workplace ritual as a waste of time and energy. PMID:10124171

Microscopic insight into the hopping transport in disordered semiconducting polymers  

NASA Astrophysics Data System (ADS)

Charge carrier transport in disordered conjugated polymers has been modeled for decades using simple phenomenological models that assume certain density of electronic states and certain analytical expression for the hopping rates between the states. The density of states is therefore believed to be the crucial property of the polymer material when electronic transport is concerned. We show here that transport properties are also strongly dependent on the proper description of transition rates. We use our recently developed multiscale method [1] for the calculation of electronic transport where transition rates are modeled taking into account the interaction with all phonon modes. Our results indicate that the widely used Miller-Abrahams model of the hopping rates predicts different behavior than our detailed model: a) It gives significantly different dependence of the mobility on temperature. b) It predicts that the concept of effective temperature could be used to describe carrier heating in electric field, in contrast to the results of the detailed simulations.

Carrier heating in disordered conjugated polymers in electric field  

SciTech Connect

The electric field dependence of charge carrier transport and the effect of carrier heating in disordered conjugated polymers were investigated. A parameter-free multiscale methodology consisting of classical molecular dynamics simulation for the generation of the atomic structure, large system electronic structure and electron-phonon coupling constants calculations and the procedure for extracting the bulk polymer mobility, was used. The results suggested that the mobility of a fully disordered poly(3-hexylthiophene) (P3HT) polymer increases with electric field which is consistent with the experimental results on samples of regiorandom P3HT and different from the results on more ordered regioregular P3HT polymers, where the opposite trend is often observed at low electric fields. We calculated the electric field dependence of the effective carrier temperature and showed however that the effective temperature cannot be used to replace the joint effect of temperature and electric field, in contrast to previous theoretical results from phenomenological models. Such a difference was traced to originate from the use of simplified Miller-Abrahams hopping rates in phenomenological models in contrast to our considerations that explicitly take into account the electronic state wave functions and the interaction with all phonon modes.

Critical Collapse of Rotating Gravitational Waves: Recent Progress  

NASA Astrophysics Data System (ADS)

Critical phenomena in general relativity have received much interest since Choptuik's pioneering work on the threshold of black hole formation in the collapse of a spherically symmetric massless scalar field. By considering a one-parameter family of initial data, the scalar field configuration would either collapse to a black hole or eventually disperse, depending on whether the parameter was larger or smaller than some critical value. Furthermore, it was found that the mass of the black hole formed follows a universal power-law scaling as a function of the parameter's distance from its critical value. Shortly afterwards, similar critical phenomena in the collapse of axisymmetric gravitational waves were discovered by Abrahams and Evans. In fact, it is now thought that critical phenomena are a generic feature of gravitational collapse under fine-tuning of initial conditions. However, surprisingly little is known about situations that include angular momentum. In this talk, I will describe recent progress in simulating the collapse of rotating gravitational waves, in which the waves may carry large angular momentum, and comment on the approach to the critical solutions in these cases.

The kinetic subsystem of light and its role in optical manipulation  

NASA Astrophysics Data System (ADS)

Optical manipulation has allowed for an increase in understanding across scientific fields including biology, chemistry, and atomic physics. Unfortunately, there is still significant debate as to how the dynamics of opticalmatter systems should be modeled. The reason for this is the myriad of formulations for the electromagnetic momentum and force density. While significant advances have been made in recent years to interpret the different formulations of electrodynamics, there remains some confusion. Most formulations include contributions from both matter and field. They may be interpreted as providing the canonical, total, or wave momentum, stress, and force. Examples include the well-known Gordon and Minkowski momenta. Conversely, it is widely accepted that the Abraham momentum of light corresponds to the kinetic subsystem. Changes in the kinetic momentum thus should provide center of mass-energy translations of matter providing a route to deriving equations of motion in optical manipulation experiments. In this paper, the idea of a kinetic formulation of electrodynamics is discussed. Consideration will be given to the three viewpoints which are most commonly argued. First, the kinetic subsystem should be postulated as a fundamental tenant of electrodynamics. Second, the kinetic subsystem of electrodynamics should not be postulated, but rather deduced by experimental and theoretical considerations. Third, a kinetic subsystem of electrodynamics cannot be uniquely defined in matter because the fields inside matter cannot be uniquely measured. Finally, it will be argued that identification of the kinetic subsystem of a particular optical manipulation experiment is not necessary nor preferred in most cases.

Synthesis and quantitative structure-antifungal activity relationships of clovane derivatives against Botrytis cinerea.  


Twenty-three clovane derivatives, nine described here for the first time, bearing substituents on carbon C-2, have been synthesized and evaluated for their in vitro antifungal activity against the phytopathogenic fungus Botrytis cinerea. The results showed that compounds 9, 14, 16, and 18 bearing nitrogen atoms in the chain attached at C-2 displayed potent antifungal activity, whereas mercapto derivatives 13, 19, and 22 displayed low activity. The antifungal activity showed a clear structure-activity relationship (SAR) trend, which confirmed the importance of the nature of the C-2 chain on the antifungal activity. On the basis of these observations, the metabolism of compounds 8 and 14 by the fungus B. cinerea, and the metabolism of other clovanes by this fungus, described previously, a pro-drug action mechanism for 2-alkoxyclovane compounds is proposed. Quantitative structure-activity relationship (QSAR) studies were performed to rationalize the results and to suggest further optimization, using a topological sub-structural molecular design (TOPS-MODE) approach. The model displayed good fit and predictive capability, describing 85.5% of the experimental variance, with a standard deviation of 9.502 and yielding high values of cross-validation determination coefficients (q2CV-LOO = 0.784 and q2boot = 0.673). The most significant variables were the spectral moments weighted by bond dipole moment (Dip), hydrophobicity (Hyd), and the combined dipolarity/polarizability Abraham molecular descriptor (Ab-pi2H).

The Muslim football player and Ramadan: current challenges.  


Islam is a monotheistic Abrahamic faith characterised by devotional orthopraxy. The actions expected of followers of Islam are closely prescribed in the Qur'an. Muslims understand Ramadan as a mandatory requirement, excused only in the event of illness, infirmity or extremes of age. Due to the increasing popularity of football among Muslims, more and more Muslim football players of all levels make the decision to follow the Ramadan fast while they need to practise and compete. Sports medicine clinicians and scientists have the responsibility to provide them with the knowledge and evidence on how exactly Ramadan fasting impacts on their performance and how to optimise their eating, drinking and sleeping in order to minimise negative effects of their religious practice, should any have been demonstrated. The first International Federation of Football Associations (FIFA) Medical Assessment and Research Centre (F-MARC) study concluded that biochemical, nutritional, subjective well-being and performance variables were not adversely affected in young male national level players who followed Ramadan fasting in a controlled environment. Match performance was however not measured and the study did not include elite level players, leading to the Ramadan consensus meeting in order to answer the remaining questions. The conclusions and recommendations published in this supplement suggest that the best coping strategies will remain individual - as is the choice to fast. PMID:22594952

A century after Flexner: the need for reform in medical education from college and medical school through residency training.  

PubMed Central

The last major change in medical education occurred almost 100 years ago following an independent investigation conducted by Dr. Abraham Flexner in 1910. Although individual institutions have implemented drastic changes in their own curriculum and the accrediting agencies have mandated other initiatives intended to maintain medical education at the cutting edge of science and technology, many facets of medical education, from the premedical requirements through medical school and residency training, have not changed in nearly half a century. There are areas that are completely lacking in the process of training physicians, and perhaps the assumption was that physicians were intelligent enough to figure this out on their own. While that may have been true in the past when things were less complicated, this approach offers too many opportunities for misadventure, ultimately to the detriment of physicians and patients. Perhaps what is needed is a more rigorous, didactic training program and more thought put into areas where judgment, morality and ethics converge to create potential hazards that can defeat the finest training, equipment and intent. Although American residency programs produce physicians fully capable of independent practice after their prescribed periods of training, there are elements of these training programs that are outdated, costly and perhaps not the best way to get to the desired endpoint. Perhaps these can be revised to more accurately reflect the changing times. This manuscript addresses some of these issues at all levels of training with recommendations for corrective action.

The Berlin Poliklinik: psychoanalytic innovation in Weimar Germany.  


After Freud proposed in 1918 the creation of "institutions or out-patient clinics [where] treatment will be free," Max Eitingon, Ernst Simmel, and other progressive psychoanalysts founded the Berlin Poliklinik, a free outpatient clinic. Guided by Weimar Republic principles of "radical functionalism," the Poliklinik and its companion inpatient service, the Schloss Tegel Sanatorium, pioneered treatment and training methodologies still used--and still debated--today. Their funding strategies, statistics, and approaches to clinical problems like length of treatment tell the history of an innovative psychoanalytic institute where men and women were generally treated in equal numbers and patients (ranging in occupational status from unemployed to professional) of all ages were treated free. Franz Alexander, Karl Abraham, Theresa Benedek, Paul Federn, Otto Fenichel, Edith Jacobson, Karen Horney, Erich Fromm, Helene Deutsch, Hanns Sachs, Sándor Radó, Hermine von Hug-Hellmuth, Wilhelm Reich, Annie Reich, and Melanie Klein all worked at the Poliklinik, and from there initiated decades of original clinical theory, practice, and education.

Stabilization and reconstruction operations: the role of the US Army Veterinary Corps.  


Stabilization and reconstruction operations in failed or failing states are vital to US security interests. These operations require a bottom-up approach, focusing on the population as the strategic center of gravity. This bottom-up approach must address the population's basic needs, as defined by Dr Abraham Maslow's hierarchy of needs, and provide a long-term means of self-sufficiency, rather than creating an "aid dependent economy." Focusing operations on agricultural projects provides relief from donor dependency, stimulates economic growth, and thwarts the power of spoilers. US Army Veterinary Corps personnel provide essential services ensuring the procurement of safe and wholesome subsistence and provision of medical care to government-owned animals. Veterinary Corps officers are also uniquely qualified to design and implement agricultural stabilization and reconstruction programs in conjunction with host-state ministries and agencies across the full range of military operations. Early, sustained engagement by veterinarians stimulates agricultural productivity, improves animal and human health, directly supports the population's hierarchy of needs on all levels, and accelerates stabilization operations by reducing the population's susceptibility to spoilers.

Van der Pol and the history of relaxation oscillations: Toward the emergence of a concept  

NASA Astrophysics Data System (ADS)

Relaxation oscillations are commonly associated with the name of Balthazar van der Pol via his paper (Philosophical Magazine, 1926) in which he apparently introduced this terminology to describe the nonlinear oscillations produced by self-sustained oscillating systems such as a triode circuit. Our aim is to investigate how relaxation oscillations were actually discovered. Browsing the literature from the late 19th century, we identified four self-oscillating systems in which relaxation oscillations have been observed: (i) the series dynamo machine conducted by Gérard-Lescuyer (1880), (ii) the musical arc discovered by Duddell (1901) and investigated by Blondel (1905), (iii) the triode invented by de Forest (1907), and (iv) the multivibrator elaborated by Abraham and Bloch (1917). The differential equation describing such a self-oscillating system was proposed by Poincaré for the musical arc (1908), by Janet for the series dynamo machine (1919), and by Blondel for the triode (1919). Once Janet (1919) established that these three self-oscillating systems can be described by the same equation, van der Pol proposed (1926) a generic dimensionless equation which captures the relevant dynamical properties shared by these systems. Van der Pol's contributions during the period of 1926-1930 were investigated to show how, with Le Corbeiller's help, he popularized the ``relaxation oscillations'' using the previous experiments as examples and, turned them into a concept.

Benjamin Alcock (1801-?) and his canal.  


Benjamin Alcock (1801-?) was a prominent anatomist from Ireland who is remembered most for his description of the pudendal canal. He was privileged to train under the great Irish anatomist, Abraham Colles. Following his training and several early teaching engagements, he was appointed as the first Professor of Anatomy and Physiology at Queen's College, Cork. He became a Fellow of the Royal College of Surgeons in Ireland. After several years of teaching at Queen's College, Alcock was forced to resign after a dispute over the Anatomy Act of 1832, during which he conveyed his disapproval of participation in the procurement of corpses for the school. Several years after his resignation, he left for the United States and removed himself from the view of the profession. His anatomical contributions were published in The Cyclopaedia of Anatomy and Physiology. The description he gave of the sheath enclosing the pudendal nerve and internal pudendal vessels is his most famous contribution to the literature. He is remembered eponymously for Alcock's canal. This article's intent is to clearly and concisely depict the life and contribution of Benjamin Alcock. PMID:22488487

Generation IV Nuclear Energy Systems Ten-Year Program Plan Fiscal Year 2005, Volume 1  

SciTech Connect

As reflected in the U.S. ''National Energy Policy'', nuclear energy has a strong role to play in satisfying our nation's future energy security and environmental quality needs. The desirable environmental, economic, and sustainability attributes of nuclear energy give it a cornerstone position, not only in the U.S. energy portfolio, but also in the world's future energy portfolio. Accordingly, on September 20, 2002, U.S. Energy Secretary Spencer Abraham announced that, ''The United States and nine other countries have agreed to develop six Generation IV nuclear energy concepts''. The Secretary also noted that the systems are expected to ''represent significant advances in economics, safety, reliability, proliferation resistance, and waste minimization''. The six systems and their broad, worldwide research and development (R&D) needs are described in ''A Technology Roadmap for Generation IV Nuclear Energy Systems'' (hereafter referred to as the Generation IV Roadmap). The first 10 years of required U.S. R&D contributions to achieve the goals described in the Generation IV Roadmap are outlined in this Program Plan.




Theoretical Study of Ultra-Relativistic Laser Electron Interaction with Radiation Reaction by Quantum Description  

NASA Astrophysics Data System (ADS)

In the near future, the intensity of the ultra-short pulse laser will reach to 1022 W/cm2. When an electron is irradiated by this laser, the electron's behavior is relativistic with significant bremsstrahlung. This radiation from the electron is regarded as the energy loss of electron. Therefore, the electron's motion changes because of the kinetic energy changing. This radiation effect on the charged particle is the self-interaction, called the “radiation reaction” or the “radiation damping”. For this reason, the radiation reaction appears in laser electron interactions with an ultra-short pulse laser whose intensity becomes larger than 1022 W/cm2. In the classical theory, it is described by the Lorentz-Abraham-Dirac (LAD) equation. But, this equation has a mathematical difficulty, which we call the “run-away”. Therefore, there are many methods for avoiding this problem. However, Dirac's viewpoint is brilliant, based on the idea of quantum electrodynamics. We propose a new equation of motion in the quantum theory with radiation reaction in this paper.

Charge separation at disordered semiconductor heterojunctions from random walk numerical simulations.  


Many recent advances in novel solar cell technologies are based on charge separation in disordered semiconductor heterojunctions. In this work we use the Random Walk Numerical Simulation (RWNS) method to model the dynamics of electrons and holes in two disordered semiconductors in contact. Miller-Abrahams hopping rates and a tunnelling distance-dependent electron-hole annihilation mechanism are used to model transport and recombination, respectively. To test the validity of the model, three numerical "experiments" have been devised: (1) in the absence of constant illumination, charge separation has been quantified by computing surface photovoltage (SPV) transients. (2) By applying a continuous generation of electron-hole pairs, the model can be used to simulate a solar cell under steady-state conditions. This has been exploited to calculate open-circuit voltages and recombination currents for an archetypical bulk heterojunction solar cell (BHJ). (3) The calculations have been extended to nanostructured solar cells with inorganic sensitizers to study, specifically, non-ideality in the recombination rate. The RWNS model in combination with exponential disorder and an activated tunnelling mechanism for transport and recombination is shown to reproduce correctly charge separation parameters in these three "experiments". This provides a theoretical basis to study relevant features of novel solar cell technologies. PMID:24448680

Improving the accuracy of simulation of radiation-reaction effects with implicit Runge-Kutta-Nyström methods  

NASA Astrophysics Data System (ADS)

The Landau-Lifshitz equation provides an efficient way to account for the effects of radiation reaction without acquiring the nonphysical solutions typical for the Lorentz-Abraham-Dirac equation. We solve the Landau-Lifshitz equation in its covariant four-vector form in order to control both the energy and momentum of radiating particles. Our study reveals that implicit time-symmetric collocation methods of the Runge-Kutta-Nyström type are superior in accuracy and better at maintaining the mass-shell condition than their explicit counterparts. We carry out an extensive study of numerical accuracy by comparing the analytical and numerical solutions of the Landau-Lifshitz equation. Finally, we present the results of the simulation of particle scattering by a focused laser pulse. Due to radiation reaction, particles are less capable of penetrating into the focal region compared to the case where radiation reaction is neglected. Our results are important for designing forthcoming experiments with high intensity laser fields.

Solute-solvent interactions in micellar electrokinetic chromatography: VII. Characterization of sodium cholate-sodium deoxycholate mixed-micellar systems.  


Micellar electrokinetic chromatography (MEKC) systems with mixed pseudostationary phases of the bile surfactants sodium cholate (SC) and sodium deoxycholate (SDC) have been characterized by means of the solvation parameter model. The importance of characterizing systems with an appropriate set of solutes that embrace a wide range of descriptor values has been proven as they can significantly influence the value of the system constants. The fit of the solvation parameter model to the experimental log k data has been compared for each SC-SDC system when the Abraham descriptors and the Poole optimized descriptors, recently proposed, are used. In both cases, the variation in MEKC surfactant composition results in similar changes in the coefficients of the correlation equations, which in turn leads to similar information on solute-solvent and solute-micelle interactions. It is demonstrated that SDC is more hydrogen-bond acidic and hydrophobic but slightly less polarizable than SC. Systems with intermediate selectivity are obtained through mixtures of both surfactants. PMID:20092822

On the Outcome Project  

PubMed Central

Background: In 2001, graduate medical education in the United States was renovated to better complement 21st century developments in American medicine, society, and culture. As in 1910, when Abraham Flexner was charged to address a relatively non-standardized system that lacked accountability and threatened credibility of the profession, Dr. David Leach led the Accreditation Council of Graduate Medical Education (ACGME) Outcome Project in a process that has substantially changed medical pedagogy in the United States. Methods: Brief review of the Flexner Report of 1910 and 6 hours of interviews with leaders of the Outcome Project (4 hours with Dr. David Leach and 1-hour interviews with Drs. Paul Batalden and Susan Swing). Results: Medical educational leaders and the ACGME concluded in the late 1990s that medical education was not preparing clinicians sufficiently for lifelong learning in the 21st century. A confluence of medical, social, and historic factors required definitions and a common vocabulary for teaching and evaluating medical competency. After a deliberate consensus-driven process, the ACGME and its leaders produced a system requiring greater accountability of learners and teachers, in six explicitly defined domains of medical “competence.” While imperfect, this construct has started to take hold, creating a common vocabulary for longitudinal learning, from undergraduate to post-graduate (residency) education and in the assessment of performance following graduate training.

The purpose of the study was to assess the permeability of mouse blood-brain barrier (BBB) to a diverse set of compounds in the absence of P-glycoprotein (Pgp) mediated efflux, to predict it using an in combo PAMPA model, and to explore its role in brain penetration classification (BPC). The initial brain uptake (Kin) of 19 compounds in both wild-type and Pgp mutant [mdr1a(?/?)] CF-1 mice was determined by the in situ brain perfusion technique. PAMPA measurements were performed, and the values were used to develop an in combo model, including Abraham descriptors. Published rodent Kin values were used to enhance the dataset and validate the model. The model predicted 92% of the variance of the training set permeability. In all, 182 Kin values were considered in this study, spanning four log orders of magnitude and where Pgp decreased brain uptake by as much as 14-fold. The calculated permeability-surface area (PS) values along with literature reported brain tissue binding were used to group molecules in terms of their brain penetration classification. The in situ BBB permeability can be predicted by the in combo PAMPA model to a satisfactory degree, and can be used as a lower-cost, high throughput first-pass screening method for BBB passive permeability.

Effect of the radiation reaction in classical regimes of interaction of ultra-strong electromagnetic fields with plasmas  

NASA Astrophysics Data System (ADS)

Radiation energy losses of electrons in ultra-intense laser fields constitute a process of major importance when considering laser-matter interaction at intensities of the order of and above 1022 W/cm2. Radiation losses can strongly modify the electron (and ion) dynamics, and are associated with intense and directional emission of high energy photons. Accounting for such effects is therefore necessary for modeling of, electron and ion acceleration and creation of secondary photon on the forthcoming ultra-high power laser facilities. To account for radiation losses in the particle-in-cell code PICLS, we have introduced the radiation friction force using a renormalized Lorentz-Abraham-Dirac model.10 Here, we present a study of the effect of radiation friction on the electron and photon energy distribution in a semi-infinite and overdense plasma. A possibillity to create a collisonless shock using an ultra intense laser field, in the context of laboratory astrophysics is discussed. The influence of the radiation reaction on the plasma dynamics is demonstrated.

Captive on a carousel: discourses of 'new' in medical education 1910-2010.  


Medical educators aim to train physicians with sound scientific knowledge, expert clinical skills and an ability to work effectively with patients, colleagues and health systems. Over the past century, educators have devoted considerable thought and effort to how medical education might be improved. Analysing the language used to describe these initiatives provides insight into assumptions and practices. The authors conducted a Foucauldian critical discourse analysis of prominent recurrent themes in the North American medical education literature. The assembled archive of texts included works of Abraham Flexner, articles from the journal Academic Medicine (including its predecessor journals) and major medical education reports. A series of recurring themes were identified, including the need to avoid over-specialization, the importance of generalism, and the need to broaden criteria for medical student selection. Analysis of these recurring themes allowed identification of a prominent and recurrent discourse of 'new.' This discourse places focus on the future, ignores the ongoing historical nature of issues, suggests a sense of urgency and enables the proposal of modest solutions. It emphasizes changes for individual future doctors, thereby limiting consideration of institutional and systemic factors. Using the image of a carousel, the regular return of themes can be seen as carousel ponies circling around repeatedly in medical education. Identification of this medical education carousel provides an opportunity for medical educators to understand the historical nature of calls for change, and to consider what kinds of reform might be required if they wish to avoid this repetition in the future.

The Anatomy of A.L.I.C.E.  

NASA Astrophysics Data System (ADS)

This paper is a technical presentation of Artificial Linguistic Internet Computer Entity (A.L.I.C.E.) and Artificial Intelligence Markup Language (AIML), set in context by historical and philosophical ruminations on human consciousness. A.L.I.C.E., the first AIML-based personality program, won the Loebner Prize as "the most human computer" at the annual Turing Test contests in 2000, 2001, and 2004. The program, and the organization that develops it, is a product of the world of free software. More than 500 volunteers from around the world have contributed to her development. This paper describes the history of A.L.I.C.E. and AIML-free software since 1995, noting that the theme and strategy of deception and pretense upon which AIML is based can be traced through the history of Artificial Intelligence research. This paper goes on to show how to use AIML to create robot personalities like A.L.I.C.E. that pretend to be intelligent and selfaware. The paper winds up with a survey of some of the philosophical literature on the question of consciousness. We consider Searle's Chinese Room, and the view that natural language understanding by a computer is impossible. We note that the proposition "consciousness is an illusion" may be undermined by the paradoxes it apparently implies. We conclude that A.L.I.C.E. does pass the Turing Test, at least, to paraphrase Abraham Lincoln, for some of the people some of the time.

Test of the Two-Dimensional Localization Scaling Relation.  

NASA Astrophysics Data System (ADS)

The scaling theory of localization(E. Abrahams, P.W. Anderson, D.C. Licciardello, and T.V. Ramakrishnan, Phys. Rev. Lett. 42, 673 (1979).)predicts electron localization at T=0 and B=0 and the following scaling relation between the localization length, ?, and the scattering length, L, ? = bLexp[(?/2)k_FL], with b ~1. We report studies on gated GaAs/Al_0.3Ga_0.7As heterostructures at different electron densities, n. We find no evidence for an insulator-metal transition in contrast to recent studies(S.V. Kravchenko, W.E. Mason, G.E. Bowker, J.E. Furneaux, V.M. Pudalov, and M. D'Iorio, Phys. Rev. B 51 7038 (1995).)on a Si MOSFET. Values of ? are determined from the variable-range hopping formula in the Anderson insulator. Values of k_FL deduced from Eq. with b ~0.3 at small n and from the Drude conductivity at large n are plotted versus n. Values from Eq. (1) in the range 0.6 < k_FL < 1.6 are in good agreement with values extrapolated from higher densities.

Atomic structure of the Si(001)-(2×1) surface  

NASA Astrophysics Data System (ADS)

We have performed an extensive set of first-principles self-consistent-field (SCF) pseudopotential total-energy and force calculations for Si(001)-(2×2) and -(2×1) surfaces to arrive at an optimized model for the 2×1 surface. We started with the symmetric dimer model proposed by Abraham and Batra (AB) based on the Stillinger-Weber potential as well as the Yin-Cohen (YC) asymmetric dimer model to carry out the optimization procedure. We confirm the short dimer bond length obtained by YC, unlike in the AB model. However, a symmetric dimer model with a substantial (0.45 Å) inward relaxation of the top layer is found to be lower in energy than the AB model and is highly competitive with a slightly modified YC model. This supports the use of the symmetric model by Pandey in the construction of the extended defect model and also in the recent spin-unrestricted model calculations. From the 2×2 cell calculations we conclude that in the small-buckling limit, some energy gain is possible, provided that the dimers are tilted in opposite directions. We also establish that there is no barrier associated with the surface dimer formation but twisting of the dimers is energetically unfavorable. A detailed account of the Hellmann-Feynman forces is given for various structures.

Mapping Environmental Partitioning Properties of Nonpolar Complex Mixtures by Use of GC × GC.  


Comprehensive two-dimensional gas chromatography (GC × GC) is effective for separating and quantifying nonpolar organic chemicals in complex mixtures. Here we present a model to estimate 11 environmental partitioning properties for nonpolar analytes based on GC × GC chromatogram retention time information. The considered partitioning properties span several phases including pure liquid, air, water, octanol, hexadecane, particle natural organic matter, dissolved organic matter, and organism lipids. The model training set and test sets are based on a literature compilation of 648 individual experimental partitioning property data. For a test set of 50 nonpolar environmental contaminants, predicted partition coefficients exhibit root-mean-squared errors ranging from 0.19 to 0.48 log unit, outperforming Abraham-type solvation models for the same chemical set. The approach is applicable to nonpolar organic chemicals containing C, H, F, Cl, Br, and I, having boiling points ?402 °C. The presented model is calibrated, easy to apply, and requires the user only to identify a small set of known analytes that adapt the model to the GC × GC instrument program. The analyst can thus map partitioning property estimates onto GC × GC chromatograms of complex mixtures. For example, analyzed nonpolar chemicals can be screened for long-range transport potential, aquatic bioaccumulation potential, arctic contamination potential, and other characteristic partitioning behaviors.

Theoretical and numerical study of axisymmetric lattice Boltzmann models  

NASA Astrophysics Data System (ADS)

The forcing term in the lattice Boltzmann equation (LBE) is usually used to mimic Navier-Stokes equations with a body force. To derive axisymmetric model, forcing terms are incorporated into the two-dimensional (2D) LBE to mimic the additional axisymmetric contributions in 2D Navier-Stokes equations in cylindrical coordinates. Many axisymmetric lattice Boltzmann D2Q9 models were obtained through the Chapman-Enskog expansion to recover the 2D Navier-Stokes equations in cylindrical coordinates [I. Halliday , Phys. Rev. E 64, 011208 (2001); K. N. Premnath and J. Abraham, Phys. Rev. E 71, 056706 (2005); T. S. Lee, H. Huang, and C. Shu, Int. J. Mod. Phys. C 17, 645 (2006); T. Reis and T. N. Phillips, Phys. Rev. E 75, 056703 (2007); J. G. Zhou, Phys. Rev. E 78, 036701 (2008)]. The theoretical differences between them are discussed in detail. Numerical studies were also carried out by simulating two different flows to make a comparison on these models’ accuracy and ? sensitivity. It is found all these models are able to obtain accurate results and have the second-order spatial accuracy. However, the model C [J. G. Zhou, Phys. Rev. E 78, 036701 (2008)] is the most stable one in terms of ? sensitivity. It is also found that if density of fluid is defined in its usual way and not directly relevant to source terms, the lattice Boltzmann model seems more stable.

Atomistic simulation on charge mobility of amorphous tris(8-hydroxyquinoline) aluminum (Alq3): origin of Poole-Frenkel-type behavior.  


The atomistic simulation of charge transfer process for an amorphous Alq(3) system is reported. By employing electrostatic potential charges, we calculate site energies and find that the standard deviation of site energy distribution is about twice as large as predicted in previous research. The charge mobility is calculated via the Miller-Abrahams formalism and the master equation approach. We find that the wide site energy distribution governs Poole-Frenkel-type behavior of charge mobility against electric field, while the spatially correlated site energy is not a dominant mechanism of Poole-Frenkel behavior in the range from 2x10(5) to 1.4x10(6) V/cm. Also we reveal that randomly meshed connectivities are, in principle, required to account for the Poole-Frenkel mechanism. Charge carriers find a zigzag pathway at low electric field, while they find a straight pathway along electric field when a high electric field is applied. In the space-charge-limited current scheme, the charge-carrier density increases with electric field strength so that the nonlinear behavior of charge mobility is enhanced through the strong charge-carrier density dependence of charge mobility.

Linear Solvation Energy Relationships in the Determination of Specificity and Selectivity of Stationary Phases.  


The retention of fifty structurally different compounds has been studied using linear solvation energy relationships. Investigations were performed with the use of six various stationary phases with two mobile phases (50/50 % v/v methanol/water and 50/50 % v/v acetonitrile/water). Packing materials were home-made and functionalized with octadecyl, alkylamide, cholesterol, alkyl-phosphate and phenyl molecules. This is the first attempt to compare all of these stationary phases synthesized on the same silica gel batch. Therefore, all of them may be compared in more complex and believable way, than it was performed earlier in former investigations. The phase properties (based on Abraham model) were used to the classification of stationary phases according to their interaction properties. The hydrophilic system properties s, a, b indicate stronger interactions between solute and mobile phase for most of the columns. Both e and v cause greater retention as a consequence of preferable interactions with stationary phase by electron pairs and cavity formation as well as hydrophobic bonds. However, alkyl-phosphate phase has different retention properties, as it was expressed by positive sign of s coefficient. It may be concluded that most important parameters influencing the retention of compounds are volume and hydrogen bond acceptor basicity. The LSER coefficients showed also the dependency on the type of organic modifier used as a mobile phase component. PMID:23125462
