Published: June 2024

The study aims to analyze the Audit Quality (AQ) factors that were perceived to be necessary by the accountants and internal auditors in municipalities of Palestine. A survey of 309 accountants and internal auditors from 155 Palestinian municipalities was conducted. The questionnaire data was statistically analyzed using Smart PLS3 software. The study discovered that auditor ethics, independence, and competence were the most significant elements in determining AQ. Meanwhile, Internal Auditing (IA), Accounting Basis (AB), and the Laws and Regulations (LR) have a moderate effect. However, the least crucial factors were Audit Fees (AF) and Audit Firm Size (AFS). The study is limited by the survey questionnaire method’s general limitations and the perceptions of accountants and internal auditors. It offers evidence on AQ from Palestine, helps the audit firms distinguish their marketing and service delivery strategies, and understands the AQ aspects sought by those clients. Moreover, the study provides the municipal councils and the regulators of the municipalities with greater knowledge on how to select the best auditors and maintain internal control measures, notably IA and the use of the accrual basis in accounting procedures. Since the findings are generally consistent with previous studies, more emphasis can be placed on the effectiveness of municipal internal control.

This study aims to examine the current issues and challenges in implementing Shariah audit practices in several Shariah-based sectors in Malaysia, namely, Islamic financial sector, Islamic Capital Market (ICM), Islamic cooperative, public Shariah-based and Public Trust Entity (PTE). Furthermore, based on the findings, several future strategies are proposed to enhance Shariah audit practices. In this study, a series of Focus Group Discussions (FGD) was employed, and 124 participants from 76 Shariah-based institutions were involved through five FGD sessions. This study discovered that each Shariah-based sector has different issues and challenges in implementing Shariah audit practices due to the current Shariah governance and assurance practices in respective sectors. Thus, three main strategies were proposed that can be used to bring Shariah audit practices to another level for these Shariah-based sectors. This includes nurturing Shariah governance and assurance, developing specific Shariah audit scopes based on the uniqueness of each Shariah-based sector, and enhancing the professionalisation of Shariah auditors. Note that this study is considered a pioneering study in identifying the issues and challenges in implementing Shariah audit practices in various Shariah-based sectors. It also contributes by proposing the main strategies to enhance Shariah audit practices as a next step in the future.

Introdução: A unidade de terapia intensiva recebe pacientes criticamente doentes, que necessitam de cuidados especializados e integrais. Comumente estes usuários permanecem restritos ao leito por tempo prolongado, ocasionando inatividade, imobilidade e disfunções osteomioarticulares severas. Objetivo: Analisar a prevalência, o grau de mobilidade e os fatores de risco para mobilização precoce em pacientes que estivessem do sétimo ao décimo dia de internação das unidades avaliadas. Métodos: Trata-se de um estudo descritivo analítico de característica transversal. Para a execução da pesquisa, foi realizada a avaliação de segurança, e escala de mobilidade de Johns Hopkins, finalizando com a análise de condutas de mobilidade realizadas no dia da avaliação, ambos via prontuário. Resultados: 100 pacientes foram incluídos (idade: 58±18 anos, sexo: 65 masc). Com relação à realização de mobilização precoce, apenas 27% pôde ser caracterizada como tal. Os participantes que estavam em ventilação espontânea apresentaram percentual maior de mobilização (63%), quando comparados aos pacientes que estavam em ventilação mecânica invasiva (33,3%). 73% dos pacientes apresentavam classificação 1 (deitado) na escala de Johns Hopkins. Quanto maior o número de riscos, entre eles, sedação e tubo orotraqueal, menor o índice de mobilização. Conclusão: Uma porcentagem significativa dos pacientes não eram mobilizados. Quanto maior o número de riscos, menor o índice de mobilização. Não houve diferença nas taxas de mobilidade, considerando os diferentes diagnósticos. Logo, faz-se necessário um maior empenho em educação em saúde para os profissionais de reabilitação.

Bispecific T-cell engagers in childhood B-acute lymphoblastic leukemia
Authors: Lyons Kaylyn Utley , Gore Lia
Published: June 2024

Immunotherapy has revolutionized treatment for a wide variety of cancers yet its use has been relatively limited in childhood malignancies. With the introduction of bispecific T-cell engagers (BiTE®) and chimeric antigen T-cell receptor technologies, previously refractory patients have attained remission, including molecularly negative states of disease, thus providing the possibility of long-term cure. Blinatumomab is a widely available CD3-CD19 BiTE that has dramatically changed the landscape of therapy for some children with precursor-B acute lymphoblastic leukemias (B-ALL) and lymphoblastic lymphomas. Challenges remain with using BiTE in a broader population although the appeal of now-confirmed reduced toxicity and deeper molecular remissions suggests that this approach will be an essential part of future treatment of childhood B-ALL. Herein, we review some of the pertinent literature covering clinical trials with blinatumomab and address future approaches and combination trials including BiTE.

Entomoremediación: Influencia de una Dieta Plástica en el Desarrollo de Tenebrio Molitor para Generar Biofertilizante
Authors: Bastidas-Proaño Daniela
Published: June 2024

El plástico es ampliamente utilizado y responsable de impactos ambientales negativos. Tal es el caso del poliestireno expandido (EPS), que presenta desafíos de revalorización por su baja densidad. Aunque ciertas larvas de insecto, como tenebrio molitor, han demostrado la capacidad de mineralizar plásticos, la insecticultura de estos aún se enfoca en obtener proteína sostenible y biofertilizante. En este estudio, se investiga la influencia de una dieta de EPS en el desarrollo larval de T. molitor durante 6 meses, y se examina cómo la dieta afecta el volumen de biofertilizante recolectado en este lapso. Se desarrollaron ensayos con tres dietas, realizando mediciones y recolección de material de manera periódica. Los resultados indican que las larvas alimentadas con un sustrato combinado, así como aquellas con una dieta orgánica, demuestran tasas de supervivencia de hasta 66%. La longitud final es inferior en la dieta inorgánica (112mm), y en las otras dietas superan los 162 mm. Las larvas de una dieta inorgánica no progresaron a pupa, demostraron un Factor de Conversión de Alimento desalentador (3,87) y produjeron menor cantidad de frass/biofertilizante (1,28g), en comparación con la dieta combinada que registró 5,11g. Los datos sugieren que la entomoremediación plástica funciona óptimamente si se cría larvas en un sustrato combinado de EPS y elementos orgánicos. Dicha condición no solo produce resultados positivos, sino que se alinea con los principios de economía circular. En consecuencia, se demuestra que una dieta combinada es ideal para abordarla como opción en el tratamiento de residuos de EPS.

Published: June 2024

Over the years, the world has tried to increase the recycling of materials, especially those of artificial origin, this in order to produce compounds that are sustainable and sustainable. Among these materials, concrete stands out as a versatile element, to which different external agents can be added; however, since many of them are not compatible with aggregates, cement or water, can cause some alterations in their mechanical performance. Therefore, the present investigation addressed the study of an artificial material called Microporous Ethylene Vinyl Acetate (MEVA), in order to evaluate its influence on the mechanical properties of structural concrete. MEVA additions were used in ranges of 5.00 %, 10.00 %, 15.00 % and 20.00 % with respect to the volume of concrete, to analyze its behavior in the mix, both in physical and mechanical properties. The results show that the workability and unit weight are affected by the increase in MEVA. Despite this, the mechanical performance showed significant increases in the compressive strength of 8.81 %, tensile of 22.86 %, flexion of 24.51 % and modulus of elasticity of 2.12 %, with the addition of 5.00 % of MEVA after 28 days. Nevertheless, at higher doses there is a reduction in said strengths. For these reasons, it is concluded that the incorporation of MEVA at 5.00 % greatly improves the mechanical properties of concrete for structural use, in relation to the theoretical design strength of 21.00 MPa.

El estudio de los materiales de empaques ha adquirido una creciente importancia, especialmente en el envasado de alimentos sensibles al oxígeno, por lo cual se han implementado diversas tecnologías para mejorar las propiedades de barrera contra el oxígeno, con el objetivo de prolongar la vida útil de los productos. En este contexto, durante esta investigación se propuso evaluar la tasa de transmisión de oxígeno (OTR) en envases fabricados mediante moldeo por inyección, a través de diferentes tipos de polipropileno (PP). El estudio se llevó a cabo con la medición de la OTR en los diferentes tipos de envases mediante un analizador por fluorescencia óptica, exponiendo los envases a una corriente de nitrógeno en un lado y a una de oxígeno puro en el otro lado. Los resultados revelaron 44 % mayor permeabilidad en contenedores que utilizaron tapas fabricadas con copolímero de polipropileno random (CPPR) y las tarrinas fabricadas con copolímero de polipropileno en bloques (CPPB), en comparación con las tarrinas y tapas que emplearon solo CPPB. Estos hallazgos indican que el tipo de material utilizado influye significativamente en la OTR, lo cual impacta en el rendimiento de los productos envasados. Los resultados proporcionan información relevante para el desarrollo de empaques más eficientes en términos de barrera de oxígeno, lo que contribuye a garantizar la calidad y la vida útil de los productos envasados.

Published: June 2024

En este documento, se realiza una revisión de las antenas de microcinta utilizadas en sistemas de transferencia y captación de energía electromagnética radiada en las bandas de microondas, en función de sus parámetros técnicos y estructurales. Lo anterior permitirá identificar aspectos destacados en el empleo de las distintas configuraciones de antenas y sugerir líneas de investigación futuras que contribuyan con el desarrollo de esta área. Para ello, se realiza una revisión de literatura de artículos de investigación, trabajos presentados en conferencias y simposios, entre otros, que permitan conocer las diferentes propuestas existentes en torno al tema de estudio. Como resultado, se encuentra que existe una gran variedad de configuraciones y técnicas para el diseño de estas antenas, con los cuales se puede modificar el patrón de radiación y mejorar la ganancia. Se concluye entonces, que no existe un patrón definido de construcción para obtener la antena ideal. Sin embargo, se abre una perspectiva a la investigación para establecer y evaluar nuevas estructuras y materiales para la optimización de este tipo de antenas utilizadas en la recolección de energía de RF como otra alternativa para la carga de dispositivos de baja potencia y el desarrollo de la tecnología de internet de las cosas (IoT).

Published: June 2024

Esta investigación técnico experimental tiene como objetivo analizar la resistencia a corte, considerando que para los perfiles laminados tipo ángulo no se cuenta con una fórmula de cálculo normalizada al emplearse como conectores de corte y que pueden ser usados en secciones compuestas. El estudio consistió en el análisis de 16 especímenes; 8 con un ángulo de 3 mm de espesor y otras 8 con 4 mm de espesor; cada grupo de 8 especímenes se dividió en dos subgrupos de 4, que se diferencian entre sí por la posición del conector a 45 y 90 grados. Al comparar los resultados con estudios de otros autores, se evidencia que el modo de falla está relacionado con la forma de la probeta, lo cual resulta en una falla prematura del concreto sobre las nervaduras. El análisis de estos ensayos resultó en la obtención de parámetros como: resistencia, ductilidad, deslizamiento y rigidez del material; independientemente de la orientación del conector, y se concluyó que el conector orientado a 90 grados es el que mayor carga resiste. En cuanto a la rigidez, los valores obtenidos son similares con investigaciones previas, lo que lleva a la conclusión que el conector orientado a 45 grados tiene una mayor rigidez característica que el orientado a 90 grados. Los mismos, según la norma establecida, tienen una ductilidad moderada y según las gráficas carga-deslizamiento los de 3 mm de espesor tienen un mayor desplazamiento que los de 4 mm, independientemente de su orientación.

Abstract— Plants are living things that need water for growth, so plant growth is also very influential on the amount of water and nutrients that can be absorbed properly in the growth process. Plants themselves get water through the soil that is absorbed by the roots, but rooted plants such as mustard greens, tomatoes, chilies, and other vegetables find it difficult to reach deeper water. In order to maintain the quality of soil moisture so that it remains stable, special handling is needed, namely regular watering by paying attention to the percentage of water content that ranges from 60% -80%. 
In today's era, technology is increasingly advanced but many people do not use it to its full potential. For example, filling the water tank still uses the old way, namely by connecting cables and turning on the water pump manually. Likewise, the plant watering system that is still manual must turn on the water faucet. This is considered ineffective because maintenance of cable maintenance is difficult, especially since the distance between the water tank and the water pump is far and it also requires energy to control the plant. Therefore, this research tool was made using an Ultrasonic Sensor as a water depth reader,a Soil Moisture Sensor as a reader of soil moisture so that it is controlled to keep humidity at 60%-80%, using a NodeMCU microcontroller as a link between the tank and the tank filling controller and also watering plants. With this system, it can help human performance so that they don't have to fill manual water tanks that require cables and also irrigate dry plants.

The increase in electricity consumption in Indonesia can increase the possibility of disruption to the electricity network system that is used as a source of AC voltage for the community. To overcome these disturbances, PT. PLN will cut off the electricity network and then carry out repairs at points where disturbances are detected. The process of disconnecting the electricity network can disrupt community activities. Advances in power electronics technology and science have produced a solution in the form of a device that can convert DC electricity to AC. The tool is an inverter. Researchers will design a full-bridge topology single-phase inverter with a 12 VDC voltage source. The microcontroller used to control the switching of the full bridge circuit and maintain voltage stability with AC voltage feedback is Arduino Uno. The output voltage of the inverter will be increased to 220 Volts using a transformer. PWM signal generation with Fast PWM mode is used to generate sinusoidal signals with a frequency of 50 Hz and reduce harmonic distortion at the output of the inverter. This thesis will make a single-phase inverter with AC output voltage feedback and it is hoped that the method used can produce an inverter with small harmonic distortion with a stable output voltage.
