Authors: McCurdy Kevin , Walker John , Pozuc David , Pitts Jordan 
Published: August 2022

The purpose of this study was to determine the relative and absolute reliability using PUSH Pro Band 2.0 IMU to measure peak velocity and power during the countermovement (CMJ) and split-squat jump (SSJ). Twenty-three resistance trained males and females completed the study. After a familiarization session, each subject completed 2 identical sessions separated by a minimum of 72 hours that included 4 loads during the CMJ (body weight, body weight plus 20, 40 and 60%) and SSJ (body weight, body weight plus 15, 30 and 45%). In each session, 3 repetitions were completed at each load in randomized order with 3 minutes rest between sets and 5 minutes rest between jump types. Dumbbells held to the side were used to add load. A waist belt was worn that contained the accelerometer. High relative (intra-class coefficient ranging from 0.86-0.99) and absolute (coefficient of variation ranging from 1.7-8.0%) reliability were found for all measures of peak velocity and power during the CMJ and SSJ. The PUSH device produced highly reliable measures of jump performance across all loads between trials and across sessions.

Published: August 2022

The general increase of heavy metal content in the soil has been largely caused by crude oil spillage. This study investigates the possibility of tomato (Lycopersicon esculentum Miller) to sorb heavy metals present in crude oil. Crude oil of 0 mL (control), 75 and 150 mL were mixed thoroughly with 15 kg of loamy soil (dry weight) in perforated plastic buckets, as the experimental pots and left for 4 days before transplanting tomato seedlings. After 12 weeks of transplanting, heavy metals analysis was carried out on plant’s fruits, leaves, stems and roots. Physicochemical analyses show that control soil had the lowest organic carbon (3.07 %) while 150 mL had the highest mean organic carbon content (8.24 %). The silt, clay and sand constituents were not significantly different (p > 0.05) in both treated and untreated soil. The control had the least pH value (6.1) while the lead (Pb) content in soil was highest in 150 mL (0.33 mg/kg) but was not significantly different (p > 0.05) from control (0.26 ) and 75 mL (0.30 mg/kg). Lead (Pb) and Cadmium (Cd) were not detected in leaves and fruits. However, bioaccumulation factor (BAF) of Cd and Ni in stem were greater than 1. Although, the concentrations of these heavy metals falls below toxic levels, its consumption could lead to adverse health effects in both man and animals through bioaccumulation or biomagnification.
HIGHLIGHTS

Countries with poor hydrocarbon pollution regulation are more challenging with oil spills, either through accidental discharges or indiscriminate disposal of hydrocarbon waste
Plants essentially need some metals such as iron, copper among others, for their growth and other metabolic activities. However, at excess of specific limits, these metals adversely affect plant growth
In this study, bioaccumulation factors (BAF) of Cd and Ni in the stem were greater than 1, this shows that the tomato plant is a hyperaccumulator of Cd and Ni from the soil

Undoped and cobalt doped copper selenide thin films have been successfully prepared unto fluorine tin oxide (FTO) substrates by electrodeposition method using copper acetate, cobalt nitrate and selenium (IV) oxide as precursors for copper, cobalt and selenium ions respectively. Deposited thin films were subjected to optical, structural, morphological, compositional and electrical analysis using spectrophotometer, x-ray diffractometer, scanning electron microscope (SEM), energy dispersive x-ray spectroscopy (EDS) and 4-point probe. Optical results observed between the wavelength range of 300 nm and 1,000 nm showed that the films have good optical responses. Absorbance values ranged between 0.1 and 0.81 while transmittance lies between 15.59 and 78.68 %. Energy band gap of the films was found to vary from 2.10 to 2.28 eV. These results showed that cobalt as a dopant could be used to modify properties of copper selenide thin films. Structural analysis showed that the deposited films are polycrystalline in nature with hexagonal structural phase. Crystallite sizes of range 27.56 to 34.27 nm were obtained while dislocation density lied between and . Microstrain ranged between and . Micrograph images showed flake-like particles that increased in size as percentage of cobalt increased. Energy dispersive spectroscope (EDS) results confirmed the incorporation of cobalt on the deposited copper selenide films. Electrical resistivity of the films increased from to while conductivity decreased from to as a result of variation in cobalt ion concentration. These properties of the deposited thin films positioned them for solar cell and optoelectronics device applications.
HIGHLIGHTS

Energy band gap of electrosynthesized cobalt doped copper selenide ranged from 2.10 to 2.28 eV
Film thickness values ranged from 48.41 and 176.79 nm. Thickness values of the films were found to increase as concentration of cobalt increase
Increase in dopant concentration resulted to shift in diffraction peaks towards larger angles
Increase in crystallite size from 27.56 - 34.27 nm was observed as dopant concentration increases
SEM images of the films revealed flake - like particles of different sizes

Authors: Perin Andréa Pavan , Campos Celso Ribeiro 
Published: August 2022

A partir de 2018, após a publicação da Base Nacional Comum Curricular, houve um aumento expressivo de pesquisas acadêmicas sobre a Educação Financeira. No entanto há a necessidade de trabalhos que investiguem as definições de Educação Financeira e apontem suas diferentes vertentes (letramento, crítica e comportamental). Nessa linha, este texto tem como objetivo analisar as diferentes concepções sobre Educação Financeira de alunos do Ensino Superior. Os dados foram coletados em uma turma de 22 alunos que cursavam uma disciplina optativa de Educação Financeira oferecida em uma instituição particular de Ensino Superior da cidade de São Paulo e organizados e analisados empregando-se a técnica do Discurso do Sujeito Coletivo. As análises indicam que os estudantes associam a Educação Financeira ao desenvolvimento de duas competências, o letramento e a comportamental. Porém, uma concepção é prevalente, ou seja, apareceu de maneira mais enfática, que é a relacionada a vertente comportamental da Educação Financeira, pois os dados mostram que os alunos esperam aprender um comportamento, seja ele relacionado com a organização ou posicionamento sobre finanças. Nosso estudo também mostrou que as diferentes competências se completam, e que desenvolvimento de uma competência pode levar mais facilmente ao desenvolvimento da outra.

Abstract
Importance: As a new Accreditation Council for Occupational Therapy Education® standard, knowledge translation (KT) is an important concept to occupational therapy. A better understanding of KT in occupational therapy research could inform its relevance to occupational therapy education, research, and practice.
Objective: To answer the question “To what extent does published U.S.-based occupational therapy research that is explicitly underpinned by a KT theory, model, or framework reflect processes and concepts outlined in the knowledge-to-action (KTA) framework?”
Design: A systematic search was conducted to purposively sample U.S.-based occupational therapy research. A content analysis of 11 articles explored concepts of the KTA framework.
Outcomes and Measures: KTA was used as a conceptual foundation.
Results: Multiple sources of data mapped onto concepts in the knowledge creation cycle and each of the first five concepts of the knowledge action cycle. We found that three concepts from the knowledge action cycle—monitor knowledge use, evaluate outcomes, and sustain knowledge use—were not well represented in the sample.
Conclusions and Relevance: Future research on the monitoring, evaluation, and sustained use of occupational therapy interventions is needed. The adoption of new interventions is important, and the knowledge of how they are sustained in practice will facilitate the clinical integration of future interventions.
What This Article Adds: Occupational therapy research that uses KT lacks an emphasis on monitoring and sustaining evidence-informed interventions. Future research on the integration of such interventions into clinical practice is needed so that best practices in occupational therapy can be promoted.
