The effects of physical activity on on-task and off-task behaviors of an elementary school student with ADHD

The purpose of this study was to explore and evaluate a possible connection between the participation in a physical activity and the on-task and off-task behaviors of an elementary school student with attention-deficit/hyperactivity disorder (ADHD). Specifically, the intervention phase applied in this study hoped to increase the on-task behaviors exhibited by the student while also decreasing off-task behaviors. After observing the student in the baseline phase, the intervention was applied based on the student’s choice of physical activity. Then, the researcher observed the student through whole interval recording of on-task behavior and partial interval recording of off-task behavior for ten minutes and in one minute intervals. Results showed an increase in her on-task behavior and a decrease in her off-task behavior during the times she participated in the physical activity. Additionally, social validity questionnaires completed by the student and classroom teacher show a positive experience with the intervention and the intention to continue using the physical activity to promote on-task behavior for the student

Pre-Therapeutic Dosimetry Employing Scandium-44 for Radiolabeling PSMA-617

In recent years, the positron emitter scandium-44 moved into the focus of research providing favorable nuclide properties for an application in nuclear medicine. Radiolabeling of PSMA-617 with scandium-44 as diagnostic match for [177Lu]Lu-PSMA-617 instead of gallium-68 would enable pre-therapeutic dosimetry in clinical setting. Due to the chemical similarities of scandium and lutetium, the in vitro and in vivo characteristics of [177Lu]Lu-PSMA-617 are more similar to [44Sc]Sc-PSMA-617 than to the 68Ga-compounds [68Ga]Ga-PSMA-617 or [68Ga]Ga-PSMA-11. [44Sc]Sc-PSMA-617 showed its potential in a clinical setting as a PET imaging agent of prostate cancer providing several advantages over gallium-68 labeled tracers. The longer half-life of the nuclide would allow, for example, an optimized patient management and treatment, long-term or late time point imaging as well as transportation to more distant PET centers. However, especially clinical applications like individual dosimetry or intraoperative applications are still under investigation

The occlusal plane inclination relative to craniofacial form: A cephalometric investigation

Background Objectives: The occlusal plane has been given much attention throughout the orthodontic literature. Studies have shown that the occlusal plane inclination varies relative to vertical and sagittal skeletal discrepencies. The Six Elements of Orofacial Harmony does not address the occlusal plane inclination as a parameter in diagnosis and treatment planning despite its spatial influence on the position of the chin. The occlusal plane inclination is considered a critical factor in treatment planning for orthognathic surgery. The objective of this study was to systematically evaluate the inclination of the occlusal plane (Op°) relative to various skeletal and dental cephalometric parameters. Methods: A sample of 105 pretreatment cephalometric radiographs, in subjects with a range of skeletal and dental morphological characteristics, was appraised. Differences in the Op° and AP measurements of pogonion relative to the GALL were evaluated among the various anteroposterior, vertical, and soft tissue facial convexity groups were compared. Correlation coefficients evaluating relationships among the cephalometric measurements were calculated. A stepwise regression analysis was performed to further elucidate the variables which contribute to changes in the Op°. Results: The occlusal plane inclination was most significantly correlated with SN-MPº, MPº, Pog\u27GALL, Pog-GALL, Pogc\u27- GALL, TVL-Pog, and S-Go. The regression analysis indicated that SN-MPº, PPº, Element IV Md Ant, PP-Msc, PP-1, Mp-Mic, Sn\u27-Me\u27, SNº, Element IV Mx Ant and Co-Gn are good predictors of Opº. There were statistically significant differences among all vertical groups for the mean Opº. The mean Opº was found to differ among Class II and III skeletal profiles and convex and concave soft tissue facial convexities. Conclusions: Opº varies relative to sagittal and vertical jaw dimensions. There is a strong relationship between the occlusal plane inclination and the vertical dimension. Hyperdivergent profiles tend to have steeper occlusal plane inclinations. Hypodivergent profiles tend to have flatter occlusal plane inclinations. There is a tendency towards steeper occlusal planes in Class II skeletal subjects and a flatter occlusal plane in Class III skeletal subjects. There is a tendency towards steeper occlusal planes in subjects with convex profiles and flatter occlusal planes in patients with concave profiles. The occlusal plane inclination is highly correlated with the measurement of soft tissue pogonion to the GALL. There is a strong correlation between the occlusal plane inclination and maxillary incisor inclination. The occlusal plane inclination should be considered when diagnosis and treatment planning to maximize dental and facial esthetics

Zonal analysis of two high-speed inlets

Using a zonal technique, thin layer Navier-Stokes solutions for two high speed inlet geometries are presented and compared with experimental data. The first configuration consists of a 3-D inlet preceded by a sharp flat plate. Results with two different grids demonstrate the importance of adequate grid refinement in high speed internal flow computations. The fine grid solution has reasonably good agreement with experimental heat transfer and pressure values inside the inlet. The other configuration consists of a 3-D inlet mounted on a research hypersonic forebody. Numerical results for this configuration have good agreement with experimental pressure data along the forebody, but not inside the inlet. A more refined grid calculation is currently being done to better predict the flowfield in the inlet

A framework for flipped learning

© 2017. Over the last few decades, with the rapid developments of mobile technology, the advent of Web 2.0 sites, and the expansion of social media, there has been an incremental use of technology in the classroom. One of the approaches for technological integration into the classroom is via flipped learning. This pedagogical method has become increasingly popular and there is a growing body of literature that is investigating the implementation of this teaching methodology in the various classrooms. The present paper is an overview of the research related to the flipped classroom. The goals are threefold: a) to provide a synthesis of the definitions of the concept of the flipped learning as used in field b) to review the various theories and models that may explain the theoretical underpinnings for flipped classroom; and c) to develop a tentative framework based on the literature

Gallium-68: Radiolabeling of Radiopharmaceuticals for PET Imaging - A Lot to Consider

Gallium-68 was applied for positron emission tomography (PET) imaging already in the early beginnings of PET imaging. Today, with the introduction of PSMA-targeting tracers (e.g. PSMA-11, PSMA-617, and PSMA-I&T), the number of clinical applications of 68Ga-radiopharmaceuticals for diagnostic imaging has grown considerably. This development was initiated and supported already in the mid-2000s by the commercial availability of 68Ge/68Ga generators designed for clinical usage. This progression was accompanied by the development of several purification methods to generator eluate as well as sophisticated 68Ga-radiopharmaceuticals. Due to the 68Ga-rush, the need for implementation of gallium-68 (depending on production route) and its certain tracers into the pharmacopeia increased. Based on the specifications given by the pharmacopeia, interest focused on the development of automated synthesis systems, 99mTc-analog kits with regard to patient as well as operator safety
