Coteaching at an Elementary School Level in a Suburban Setting

Since leaders of a Central New York school implemented integrated cotaught (ICT) classrooms, no local investigation of ICT has taken place, leaving district administrators without empirical evidence of the value and effectiveness of the ICT services. The purpose of this study was to investigate the association between ICT services and student academic achievement in English language arts (ELA) and mathematics, as measured by the New York State ELA and mathematics assessments for 4th and 5th graders. Vygotsky\u27s paradigm of cognitive development, which states that learners acquire knowledge through collaborative interactions with other students, guided this study because ICT classrooms emphasize social learning for students of all abilities. Research questions were used to determine the differences in ELA and mathematics performance between students with disabilities (SWD) in ICT and non-ICT classroom settings. An analysis of covariance compared math and ELA achievement of 4th and 5th grade classes from the 2008-2009 academic year (AY), 1 year prior to ICT implementation, to 4th and 5th grade classes from the 2009-2010 AY, 1 year after ICT implementation. With a census sample of 103 students, both 4th and 5th grade ICT classes scored significantly higher on the ELA than the non-ICT classes, p = .011 and p = .001, respectively. Also, both 4th and 5th grade ICT classes outperformed their non-ICT counterparts significantly in mathematics, p \u3c .001 and p \u3c .001, respectively. This study contributes to social change by informing administrators, teachers, and the educational community that the provision of special education services (ICT) in general education classrooms is associated with increased academic achievement for SWD

Zygomycosis Associated with HIV Infection and Liver Transplantation

Zygomycosis is an increasing threat to patients with human immunodeficiency virus (HIV) infection. Zygomycosis (formerly called mucormycosis) is the fungal infection with Mucor, Rhizopus, or other species that share a common morphology of large empty pauciseptate hyphae with rare random-angle branching and a collapsed “twisted ribbon” appearance. Morphology allows a specific diagnosis on frozen section or smear prior to growth and identification of the fungi in culture which makes it improtant because treatment is different than that for more common mycoses such as candidiasis and aspergillosis. We present an informative and illustrative case of zygomycosis in a patient with HIV infection and liver transplantation

Follicular fluid high density lipoprotein-associated micronutrient levels are associated with embryo fragmentation during IVF

To investigate whether follicular fluid lipid-soluble micronutrients are associated with embryo morphology parameters during IVF. Follicle fluid and oocytes were obtained prospectively from 81 women. Embryo morphology parameters were used as surrogate markers of oocyte health. HDL lipids and lipid-soluble micronutrients were analyzed by high-pressure liquid chromatography. Non-parametric bi-variate analysis and multivariable ordinal logistic regression models were employed to examine associations between biochemical and embryo morphology parameters. Follicular fluid HDL cholesterol (r = −0.47, p < 0.01), α-tocopherol (r = −0.41, p < 0.01), δ-tocopherol (r = −0.38, p < 0.05) and β-cryptoxanthine (r = −0.42, p < 0.01) are negatively correlated with embryo fragmentation. Ordinal logistic regression models indicate that a 0.1 μmol/L increase in β-cryptoxanthine, adjusted for γ-tocopherol, is associated with a 75% decrease in the cumulative odds of higher embryo fragmentation (p = 0.010). Follicular fluid HDL micronutrients may play an important role in the development of the human oocyte as evident by embryo fragmentation during IVF

Anàlisi de compressors instal·lats en vehicles ferroviaris i optimització del seu funcionament (Sysloc)

[ES] Los vehículos ferroviarios fabricados por la empresa Stadler Rail Valencia S.A.U. cuentan con un compresor principal para el sistema de producción de aire que se va a almacenar en los depósitos equipados en los diferentes vehículos para distintas funciones neumáticas principalmente utilizado ese aire comprimido por el sistema de frenado. Stadler Rail Valencia S.A.U. dispone de un hardware, denominado TWC (Train-to-Wayside Communication System) y un software nombrado Sysloc, con la finalidad de la recopilación de datos globales de toda la flota. Ambas herramientas, se cumplimentan, entre otras muchas cosas, permitiendo la visualización y exportación de los datos recopilados. Para obtener parámetros de funcionamiento concretos. El grupo de sistemas mecánicos del departamento de ingeniería de la empresa presenta la tesitura en analizar la recopilación de datos a gran escala sobre el comportamiento del compresor principal. Por lo tanto, el proyecto se centra en el análisis de los datos recopilados y la optimización sobre el rendimiento de los arranques del compresor sobre los vehículos ferroviarios fabricados por la empresa, por medio del desarrollo de una nueva herramienta que analice los datos exportados y genere un informe estadístico sobre el funcionamiento de la producción de aire. El informe generado por la nueva herramienta determina si la operación de producción de aire es la esperable, correcta o si, por el contrario, es susceptible de derivar en desgaste excesivo y fallo prematuro de alguno de sus componentes de manera que se pueda anticipar una acción de mantenimiento necesaria y valorar acciones correctivas al diseño del sistema.[EN] Railway vehicles manufactured by Stadler Rail S.A.U Valencia have the central compressor for the air production system to be stored in the tanks equipped in the different vehicles for different pneumatic functions, mainly used by the braking system. Stadler Rail S.A.U Valencia have hardware TWC (Train-to-Wayside Communication System) and a software named Sysloc to collect global data of the whole fleet. Both tools are completed, among many other things, allowing the visualization and export of the collected data. To obtain specific operating parameters. The mechanical systems group of the company's engineering department is faced with the challenge of analyzing large-scale data collection on the behavior of the main compressor. Therefore, project focuses on the analysis of collected data and the optimization on the compressor starts performance on the railway vehicles manufactured by the company, through the development of a new tool that analyzes the exported data and generates a statistical report on the performance of the air production. The report generated by the new tool determines if the air production operation is as expected, correct or if, on the contrary, it is likely to lead to excessive wear and premature failure of any of its components so that a necessary maintenance action can be anticipated. Corrective actions to the system design can be assessed.Mejías Ocque, CJ. (2022). Análisis de compresores instalados en vehículos ferroviarios y optimización de su funcionamiento (Sysloc).
