Effect of Honey a Natural Sweetener with Several Medicinal Properties on the Attributes of a Frozen Dessert Containing the Probiotic Lactobacillus acidophilus  [PDF]
Abigail Greenbaum, Kayanush J. Aryana
Open Journal of Medical Microbiology (OJMM) , 2013, DOI: 10.4236/ojmm.2013.32015
Abstract: Lactobacillus acidophilus has several health advantages. Honey has several medicinal properties and is also a natural sweetener which could be used in frozen desserts. There are various types of honey based on color namely, light, amber and dark. Influence of honey on attributes of a probiotic frozen dessert is not known. The objective was to study the effect of light, amber colored and dark honey on the Lactobacillus acidophilus counts and quality attributes of probiotic ice cream. Ice creams were manufactured with use of Lactobacillus acidophilus at 50 g of frozen culture concentrate per 7.75 liters of ice cream mix and with the use of light or amber or dark honey individually. Control had no honey and was sweetened with sugar. Use of honey increased Lactobacillus acidophilus counts and viscosity, while decreased pH and melt down volume. Light honey ice cream had flavor and appearance scores comparable to the control vanilla ice cream. Light honey can be recommended for the manufacturing Lactobacillus acidophilus probiotic ice creams thus having a frozen dessert with the health advantageous medicinal properties of honey.
Online Courses and Online Teaching Strategies in Higher Education  [PDF]
Abigail Mitchell
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.523225
Abstract: Online faculty need to engage the student. Online course work is now an integral element of mainstream higher education. Online courses often lack face-to-face interaction, peer interaction, faculty feedback and the lack of community. Engagement of the learner is essential for learning and promoting student satisfaction. There are online teaching strategies that could enhance a student’s perception of engagement. This manuscript was completed by a literature review process.
Magnetization and spin-spin energy diffusion in the XY model: a diagrammatic approach
Daniel Greenbaum
Physics , 2005, DOI: 10.1016/j.jmr.2005.10.011
Abstract: It is shown that the diagrammatic cluster expansion technique for equilibrium averages of spin operators may be straightforwardly extended to the calculation of time-dependent correlation functions of spin operators. We use this technique to calculate exactly the first two non-vanishing moments of the spin-spin and energy-energy correlation functions of the XY model with arbitrary couplings, in the long-wavelength, infinite temperature limit appropriate for spin diffusion. These moments are then used to estimate the magnetization and spin-spin energy diffusion coefficients of the model using a phenomenological theory of Redfield. Qualitative agreement is obtained with recent experiments measuring diffusion of dipolar energy in calcium fluoride.

"Wenn ich nicht nerv s bin, mach ich mir Sorgen – macht das Sinn?" Der Gebrauch von Emotionsbegriffen in Leistungsbeschreibungen von Athleten "If I'm Not Nervous, I'm Worried, Does That Make Sense?": The Use of Emotion Concepts by Athletes in Accounts of Performance "Si no estoy nervioso, estoy preocupado, tiene eso sentido?": el uso de los conceptos de emoción que hacen los atletas al relatar el rendimiento

Abstract: Traditionell hat sich die Erforschung von Emotionen im Sport auf den Einfluss spezifischer Emotionen, im Besonderen der Angst, auf die Leistung konzentriert. Dieser Artikel behandelt Emotionen aus der Perspektive der Diskursiven Psychologie und nutzt hierbei die Methoden der Diskursanalyse und der Konversationsanalyse. Auf der Basis von Interviewdaten von Hochleistungssportlern untersucht dieser Artikel den Gebrauch von Emotionsbegriffen bei Beschreibungen athletischer Leistungen. Was diese Analyse zeigt, ist, dass obwohl Athleten behaupten, spezifische Emotionen wie Nervosit t seien bei sportlichen Leistungen normal, das Empfinden solcher Emotionen in der Vorbereitung zu einem Wettbewerb von ihnen nicht erw hnt wird, wenn sie ihre Beschreibungen von Versagen konstruieren. Im Unterschied zur traditionellen sportspsychologischen Forschung, die Emotionen, z.B. Angst, als quantifizierbar betrachtet, demonstriert dieser Artikel, dass Emotionsbegriffe eine vielf ltige Interaktionsbasis darstellen, die in unsere Diskurspraktiken eingebettet ist. URN: urn:nbn:de:0114-fqs0301105 Traditionally research into emotions in sport has focused on the impact of specific emotions upon performance, most notably anxiety. This paper approaches emotion from the perspective of discursive psychology, drawing on the methods of discourse analysis and conversation analysis. Using interview data from high level athletes, this paper examines the uses of emotion concepts in accounts of athletic performance. What becomes apparent through the analysis is that athletes claim that specific emotions such as nervousness are normal in sporting performance. In contrast, when accounting for failure, the athletes construct their build-up to the competition as containing no experience of these emotions. Rather than in traditional sports psychological research whereby emotions are seen to be quantifiable, this paper demonstrates how emotion terms form a rich interactional currency that are embedded within our accounting practices. URN: urn:nbn:de:0114-fqs0301105 Tradicionalmente la investigación sobre las emociones en el deporte se ha centrado en el impacto de las emociones específicas sobre la acción, principalmente en el caso de la ansiedad. Este artículo se aproxima a la emoción desde la perspectiva de la psicología discursiva, a través de los métodos de análisis de discurso y análisis de la conversación. Utilizando los datos de entrevistas a atletas de alto nivel, el artículo examina el uso de los conceptos de emoción en relatos del rendimiento atlético. Lo que parece evidente a través del
"The Man of these Infinite Possibilities": Max Ernst’s Cinematic Collages
Abigail Susik
Contemporaneity : Historical Presence in Visual Culture , 2011, DOI: 10.5195/contemp.2011.27
Abstract: On more than one occasion in his critical writings of the 1920’s, surrealist leader André Breton compared Max Ernst’s collages to cinema. In his first essay on the artist in 1921, Breton aligned Ernst’s collages with cinematic special effects such as slow and accelerated motion, and spoke of the illusionistic ‘transformation from within’ that characterized Ernst’s constructed scenes. For Breton, Ernst’s collages employing found commercial, scientific and journalistic images approximated the naturalistic movement of film, and thereby contributed to the radical obsolescence of traditional two-dimensional media such as painting and drawing, which remained frozen in stillness. Thus, Ernst’s images were provocative witnesses to the way in which modern technology fundamentally altered the perspectivally-ordered picture plane. But at the same time that Ernst’s collages rendered painting obsolete, they likewise depended upon fragments of outmoded popular culture themselves. For Breton, Ernst was a magician, “the man of these infinite possibilities,” comparable to cinematic prestidigators like turn-of-the-century filmmaker Georges Méliès. By drawing on the influence of recently outmoded popular culture such as early trick films, Ernst provides a crucial early example of the post-war fixation on counter-temporalities and anti-production. At once technologically advanced and culturally archeological, Ernst’s collages cannily defy strict categorization as “Modernist.”
Invariants of curves in RP^2 and R^2
Abigail Thompson
Mathematics , 2006, DOI: 10.2140/agt.2006.6.2175
Abstract: There is an elegant relation found by Fabricius-Bjerre [Math. Scand 40 (1977) 20--24] among the double tangent lines, crossings, inflections points, and cusps of a singular curve in the plane. We give a new generalization to singular curves in RP^2. We note that the quantities in the formula are naturally dual to each other in RP^2, and we give a new dual formula.
Finding geodesics in a triangulated 2-sphere
Abigail Thompson
Mathematics , 2014,
Abstract: Let S be a triangulated 2-sphere with fixed triangulation T. We apply the methods of thin position from knot theory to obtain a simple version of the three geodesics theorem for the 2-sphere [5]. In general these three geodesics may be unstable, corresponding, for example, to the three equators of an ellipsoid. Using a piece-wise linear approach, we show that we can usually find at least three stable geodesics.
Using First Passage Statistics to Extract Environmentally Dependent Amino Acid Correlations
Benjamin D. Greenbaum, Pradeep Kumar, Albert Libchaber
PLOS ONE , 2014, DOI: 10.1371/journal.pone.0101665
Abstract: In this work, we study the first passage statistics of amino acid primary sequences, that is the probability of observing an amino acid for the first time at a certain number of residues away from a fixed amino acid. By using this rich mathematical framework, we are able to capture the background distribution for an organism, and infer lengths at which the first passage has a probability that differs from what is expected. While many features of an organism's genome are due to natural selection, others are related to amino acid chemistry and the environment in which an organism lives, constraining the randomness of genomes upon which selection can further act. We therefore use this approach to infer amino acid correlations, and then study how these correlations vary across a wide range of organisms under a wide range of optimal growth temperatures. We find a nearly universal exponential background distribution, consistent with the idea that most amino acids are globally uncorrelated from other amino acids in genomes. When we are able to extract significant correlations, these correlations are reliably dependent on optimal growth temperature, across phylogenetic boundaries. Some of the correlations we extract, such as the enhanced probability of finding, for the first time, a cysteine three residues away from a cysteine or glutamic acid two residues away from an arginine, likely relate to thermal stability. However, other correlations, likely appearing on alpha helical surfaces, have a less clear physiochemical interpretation and may relate to thermal stability or unusual metabolic properties of organisms that live in a high temperature environment.
Perspective: Identification of genetic variants associated with dopaminergic compensatory mechanisms in early Parkinson's disease
Lior Greenbaum,Yael Barhum,Bernard Lerer
Frontiers in Neuroscience , 2013, DOI: 10.3389/fnins.2013.00052
Abstract: Parkinson's disease (PD) is slowly progressive, and heterogeneity of its severity among individuals may be due to endogenous mechanisms that counterbalance the striatal dopamine loss. In this perspective paper, we introduce a neuroimaging-genetic approach to identify genetic variants, which may contribute to this compensation. First, we briefly review current known potential compensatory mechanisms for premotor and early disease PD, located in the striatum and other brain regions. Then, we claim that a mismatch between mild symptomatic disease, manifested by low motor score on the Unified PD Rating Scale (UPDRS), and extensive Nigro-Striatal (NS) degeneration, manifested by reduced uptake of [123I]FP-CIT, is indicative of compensatory processes. If genetic variants are associated with the severity of motor symptoms, while the level of striatal terminals degeneration measured by ligand uptake is taken into account and controlled in the analysis, then these variants may be involved in functional compensatory mechanisms for striatal dopamine deficit. To demonstrate feasibility of this approach, we performed a small “proof of concept” study (candidate gene design) in a sample of 28 Jewish PD patients, and preliminary results are presented.
