Straight rod with different order of thickness

In this paper, we consider rods whose thickness vary linearly between \eps and \eps^2. Our aim is to study the asymptotic behavior of these rods in the framework of the linear elasticity. We use a decomposition method of the displacement fields of the form $u=U\_e + \bar{u}$, where $U\_e$ stands for the translation-rotations of the cross-sections and $\bar{u}$ is related to their deformations. We establish a priori estimates. Passing to the limit in a fixed domain gives the problems satisfied by the bending, the stretching and the torsion limit fields which are ordinary differential equations depending on weights.Comment: in Asymptotic Analysis, IOS Press, 201

Cause Branding Lizzo and the Body Positivity Movement

Known for her songs about self love and acceptance, Lizzo has become a body positive icon and a role model for so many people with larger bodies since her rise to fame. This paper is an analysis of Lizzo’s place in the current body positive moment as a fat, Black woman and the ways in which she has been forced to participate in fat activism and fat resistance due to her identity. This paper will also analyze the ways in which Lizzo’s shapewear brand Yitty is branded– is it positive inclusion or is it a case of cause branding

Fatty Acid Profile In Ruminal Content And Blood Plasma Of Finishing Beef Cattle, Supplemented With Different Sources Of Fat

Eight steers were used in a replicated 4 x 4 Latin square design experiment to study the rumen metabolism of polyunsaturated fatty acids. The animals were fed a concentrate diet based on cracked corn grain, corn silage and hay fescue (K31). The dietary fat treatments were a negative control, tallow added at 60g/day, fish oil at 60g/day and heterotrophically grown microalgae high in DHA at 100g/day. Treatments were incorporated immediately prior to feeding each day and dosed through a ruminal fistula mixed with 0.45kg of the diet. Animals were fed at 1.75 x NEm once daily during adaptation then switched to twice daily during sample collection. Samples rumen, reticulum and omasal contents were used to determine ruminal digestion and metabolism of fatty acids while urine and feces were collected to determine diet digestibility and N balance. The experiment was analyzed as a Latin Square design with a 2 x 2 factorial using mixed models in SAS. There was no difference among treatments for DMI, urine or fecal excretion, N balance, total VFA concentrations, omasal or reticular flow, and apparent digestibility. Fat treatments had lower blood plasma C18:0 than control. Algae increased flow of C18:1 isomers and increased DHA in plasma

FACTORS INHIBITING THE IMPLEMENTATION OF INQUIRY-BASED LEARNING AND PROJECT-BASED LEARNING IN THE K–12 NEW YORK STATE SOCIAL STUDIES CLASSROOM Author(s): Joseph Pesqueira

Research has shown that a majority of students retain information and learn much more effectively through instructional approaches that put them in control. Student-centered approaches to instruction, such as Inquiry-Based and Project-Based Learning are considered to be effective and engaging methods of instruction aimed at increasing student learning. In the K-12 social studies classroom, these types of learning experiences are few and far between. This study analyzes the factors, both internal and external, that social studies instructional leaders believe are inhibiting a more wide-scale implementation of Inquiry-Based and/or Project-Based learning in the classroom. This study looks at instructional leaders in numerous districts in the Northeastern United States. Methods of data collection include one-on-one semi structured interviews. This study reveals the following emerging themes: time constraints, resistant teachers, state mandated curriculum, and state mandated standardized tests all converge to create a system that does not value Inquiry-Based and/or Project-Based Learning. This study finds that the role of the instructional leader is to build trust, to support teachers, and to find pockets of success with this type of learning, especially in areas where the above-mentioned themes are less of an issue in the day-to-day classroom experience. Recommendations include building relationships and trust with teachers and putting less emphasis on standardized testing results. These recommendations will help social studies instructors navigate through some of the barriers to embedding this type of instructional practice in the K-12 Social Studies classroom

Art & Capitalism

This research paper explores the impact which the economic conditions of capitalism have had and continue to have on art. Through analysis of various case studies and other examples of the predatory nature of capitalism being expressed in the art world, the paper highlights the issues brought about by the commodification of art, such as the diminishing quality and authenticity of works of art. The paper also investigates the role of the art market, and how it derives the value of art from the status of the artist rather than artistic merit of the work. Research into the economic conditions of artists is also presented, highlighting the necessity of status in living as an artist. This research is presented with the hope that there can be a reevaluation of the relationship between capitalism and art while advocating for alternative approaches that prioritize the intrinsic value of art rather than its monetary value.https://orb.binghamton.edu/research_days_posters_2023/1071/thumbnail.jp

Mechanisms of Programmed Nutrition in Finishing Cattle \u3ci\u3e in Vivo \u3c/i\u3e and Ruminal Parameters of Amaize Supplementation \u3ci\u3e in Vitro\u3c/i\u3e

Programmed Nutrition Beef Program (Alltech Inc.) is a dietary supplement that contains Aspergillus oryzae fermentation extract with α-amylase activity that could reduce the use of feed additives such as monensin and tylosin in conventional feedlot diets. This study examines the changes in rumen fermentation resulting from feeding monensin/tylosin and Programmed Nutrition Beef Finisher. The goal was to determine if these shifts in rumen fermentation contribute to the Programmed Nutrition response observed in vivo. This study also analyzes how different levels of α-amylase (Amaize)supplementation impacts feedstuff degradation and utilization in vitro. In vivo experiment used eight steers in a replicated 4 x 4 Latin square design, and measured heat production, ruminal pH, and ruminal volatile fatty acid (VFA) concentrations for 48 hours. The in vivo study measured by urine and fecal output; dietary digestibility, nitrogen balance, 15N-glycine protein turnover, and energy balance. In vitro experiment used rumen fluid from three cannulated steers to measure in vitro gas production, rate of degradation, and starch degraded for different feedstuffs with or without Amaize. In vivo study determined that inclusion of Programmed Nutrition did not increase average daily gain, ruminal pH, ruminal VFA production, nitrogen digestibility, or methane production. Feeding Programmed Nutrition with monensin and tylosin can decrease acid detergent fiber (ADF) digestibility. In vitro study determined that in vitro gas production after 24-h increases when dry rolled barley is incubated with Amaize. Rate of degradation increases when dry rolled corn, corn steam-flaked at 26 lb/bu, retrograde steam-flaked corn, and steam-flaked barley are incubated with Amaize. Starch degraded after 2-h incubation increases when steam-flaked corn and retrograded steam-flaked corn are incubated with Amaize

Homogenización de problemas elípticos en dominios finos con fronteras oscilantes

Tesis inédita de la Universidad Complutense de Madrid, Facultad de Ciencias Matemáticas, Departamento de Matemática Aplicada, leída el 01-02-2016Los dominios finos, es decir, dominios sustancialmente más pequeños en alguna o varias de sus direcciones que en el resto, aparecen en muchos campos de la ciencia. Por ejemplo, dinámica de fluídos (lubricación, conducción de fluídos en tubos delgados, dinámica de oceanos...), mecánica de sólidos (barras delgadas, placas o cáscaras) o incluso en fisiología (circulación de la sangre). Así, el amplio número de posibles aplicaciones a situaciones reales ha hecho que la investigación de modelos de ecuaciones en derivadas parciales en dominios finos se convierta en un tema muy estudiado en los últimos años. Desde un punto de vista matemático, el estudio de las soluciones de una EDP en un dominio fino es un caso particular de la cuestión general relativa a cómo la variación de los dominios afecta al comportamiento de las soluciones de la EDP. En este marco, obtener la ecuación límite del modelo considerado, comparar la solución de la ecuación límite y las soluciones del problema en el dominio fino, analizar los coeficientes de la ecuación límite y comprender cómo la geometría del dominio afecta a la ecuación límite son algunos de los objetivos que deberían ser alcanzados. De hecho, es importante señalar que este tipo de cuestiones no sólo proporcionan importantes resultados teóricos sino que son muy relevantes desde el punto de vista de las aplicaciones. Por ejemplo, ser capaz de reducir el problema original a un problema mucho más sencillo, problema límite, que refleje las principales características del problema de partida puede ser muy útil para ingenieros y físicos...Thin domains, that is, domains where one or several of their characteristic directions are substantially smaller than the others, appear in many fields of science, like fluid dynamics (lubrication, conduction of fluids in thin tubes, ocean dynamics...), solid mechanics (thin rods, plates or shells) or even physiology (blood circulation). Thus, the wide possibilities of applying the mathematical results to real situations has made that partial differential equations on thin domains becomes a very studied topic over the last years. From a mathematical point of view, the study of the solutions of a PDE on thin domains is a particular case of the general question concerning the effects of the variation in domains on the behavior of the solutions of the PDE. In this framework, obtaining the limit equation of the model considered on the thin domain, comparing the limit solution and the solutions of the equation defined on the thin domain, analyzing the coefficients of the limit equation and understanding how the geometry of the thin domains affects the limit equation are some of the main goals that should be reached. In fact, answering this kind of questions not only provide important theoretical results, it is also very interesting for the applications. For instance, being able to reduce the original problem to an easier to handle limit problem, which reflects most of important features of the original one is very useful for engineers and applied scientists...Depto. de Análisis Matemático y Matemática AplicadaFac. de Ciencias MatemáticasTRUEunpu
