Authors: Janpetch Natapong , Trakolkul Chokchai , Plitsiri Itthi , Thepjunthra Wiphada 
Published: January 2025

This paper aims to study the development of bricks without burning, mixing para rubber latex, and compressing them with the technology of interlocking block production. The ratio of cement, lateritic soil, and water used in the mix was 1:6:11, while the percentage of para rubber latex (PRL) added was 2.5, 5, 7.5, 10, and 12.5% of the cement weight. The optimal PRL content (2.5%–7.5% by cement weight) enhances compressive strength, reduces water absorption, and improves durability, meeting the Thai industrial standard (TIS 77-2545). The PRL7.5 mixture achieved the highest performance, with a compressive strength of 21.42 MPa and a water absorption rate of 7.55%. These advancements are credited to the polymer film network formed from PRL during the hydration process, which strengthens particle bonds and reduces porosity. However, PRL content exceeding 7.5% leads to performance reductions, attributed to thicker polymer films and particle aggregation, which create larger voids within the material. Furthermore, the modified unfired bricks demonstrated enhanced crack resistance, increased ductility, and superior thermal insulation properties. Thermal tests of masonry walls confirmed that unfired bricks provide better thermal insulation. Temperature measurements revealed that houses constructed with unfired bricks consistently maintained cooler indoor temperatures compared to those made with fired bricks, indicating improved thermal efficiency. Environmentally, unfired bricks eliminate carbon emissions from firing processes and offer simpler, more energy-efficient production methods. These bricks provide sustainable alternatives to fired bricks, promoting both environmental and economic benefits for brick-making communities. Doi: 10.28991/CEJ-2024-010-12-05 Full Text: PDF
Interventions Supporting New Graduate Nurse Transition into Critical Care: A Systematic Review
Authors: Vanderspank-Wright Brandi 
Published: January 2025

Background: New graduate nurses have reported feelings of disorientation, discouragement, overwhelm and lack of confidence as they transition from nursing school to the practice environment. These feelings and a poor transition to practice can lead to burnout and turnover. New graduate nurses generally have a high turnover risk. Given the demands of specialty nursing practice environments like the intensive care unit, new graduates transitioning to critical care may be at an even higher risk of a poor transition to practice and risk of turnover.
Aims: To present preliminary findings from a systematic review that aimed to identify, describe and report on the effectiveness of interventions that support new graduate nurse transition into critical care settings.
Methods: A systematic review modelled on Joanna Briggs Institute methodology was designed. A systematic, peer-reviewed search was conducted in the following databases: OvidMEDLINE ALL, Embase Classic+ Embase, PsychINFO on OVID, CINAHL and Education Source on Ebsco, Nursing and Allied Health and ERIC databases, in addition to a grey literature search. For inclusion, the population of interest was new graduate nurses and all forms of intervention about transitioning new graduate nurses into critical care clinical practice were considered. Contexts of care encompassed all critical care settings as well as emergency departments.
Findings: At this stage of the review, twenty-six articles met inclusion criteria encompassing interventions implemented in four countries: USA, Canada, China and Australia. Findings related to intensive care units as well as emergency departments were reported. All interventions were unique in nature resulting in a significantly heterogeneous sample. Where qualitative designs were used, four synthesized themes were generated.
Conclusions: Preliminary review findings suggest that, to date, interventions implemented to support new graduate nurse transition into intensive care unit and emergency department contexts are unique and thus heterogeneous in nature. Despite the heterogeneity, common intervention elements are discernable and provide some direction regarding practices that support new graduate transition into critical care.

This research aims to redesign the accounting model for micro, small and medium enterprises (MSMEs) that is suitable for banking financing. The population in this research is MSMEs in Mataram City which have the potential to be financed by banking according to the 2023 Bank Indonesia MSMEs profile database. The sample was determined using a judgment sampling method so that MSMEs with the individual business criteria "Nasi Uduq" were selected as the research location. The main subjects in this research are MSMEs business owners. Data collection methods were carried out by interviews, observation and documentation. The data analysis technique was carried out using descriptive analysis. The research results show that accounting remodeling is very important in increasing the readiness and ability of MSMEs to obtain financing from banks. The application of the accounting model carried out by MSMEs "Nasi Uduq" in the recording aspect is still at level 1 stage, namely recording transactions which are still done manually, not yet separating recording based on type of transaction, and not yet separating recording between business transactions and personal transactions. In the transaction classification aspect, ledger posting has not been carried out, in the transaction summarization aspect, the trial balance has not been prepared or adjusting journal entries have been carried out and in the financial reporting aspect it has not been carried out comprehensively and does not reflect the actual conditions.
Advancements in Understanding Nucleation and Growth Phenomena Of Electrochemical Phase Formation Processes: Contributions from UAM Research
Authors: Palomar-Pardavé Manuel Eduardo 
Published: January 2025

This work entails a review of the research conducted at “Universidad Autónoma Metropolitana”, UAM, on the nucleation and growth phenomena involved during the electrochemical phase formation processes (EPF). Specifically, these processes include metal electrodeposition, electrosynthesis of conductive polymers or synthetic metals, anodic film formation, and the electrochemical condensation of surfactant micelles. The primary contributions of these studies focus on developing chemical-physical theoretical models capable of determining the mechanism and kinetics of these EPF processes. This is achieved through the analysis of experimental potentiostatic current density transients recorded in both aqueous and deep eutectic solvents. Furthermore, the resulting modified electrodes are applied to various significant applications, such as green energy generation using direct alcohol fuel cells, the development of electrochemical sensors for neurotransmitters and other biologically important substances, and corrosion and environmental protection.

Resumen. Este trabajo revisa la investigación realizada en la Universidad Autónoma Metropolitana (UAM) sobre los fenómenos de nucleación y crecimiento involucrados en los procesos de formación electroquímica de fases (EPF). Específicamente, estos procesos incluyen la electrodeposición de metales, la electrosíntesis de polímeros conductores o metales sintéticos, la formación de películas anódicas y la condensación electroquímica de micelas de surfactantes. Las principales contribuciones de estos estudios se centran en el desarrollo de modelos teóricos fisicoquímicos capaces de determinar los mecanismos y la cinética de estos procesos EPF. Esto se logra a través del análisis de transitorios potenciostáticos de densidad de corriente experimentales registrados en disolventes acuosos y eutécticos profundos. Además, los electrodos modificados resultantes se utilizan en diversas aplicaciones significativas, como la generación de energía verde mediante celdas de combustible de alcoholes directos, el desarrollo de sensores electroquímicos para neurotransmisores y otras sustancias biológicamente importantes, así como la protección contra la corrosión y la protección ambiental.

A Langmuir-Hinshelwood kinetic model is proposed to describe the anisole hydrodeoxygenation over a Ru/TiO2 catalyst in a continuous fixed-bed reactor. Key operating parameters, such as pressure, temperature, and weight hourly space velocity, were studied to ensure operation within the kinetic regime. The proposed kinetic model was successfully validated, and two adjacent catalytic sites were considered: one dedicated to the dissociative adsorption of hydrogen and the other to the adsorption and reaction of anisole and its reaction products. The model demonstrated a good fit with the experimental data, revealing a preference for the demethoxylation pathway leading to benzene formation over the demethylation pathway, which favors phenol formation. Characterization of the Ru/TiO2 catalyst using XRD, TPR-H2, TPD-NH3, and XPS revealed the presence of highly dispersed Ru particles and oxophilic sites, including both acidic sites and oxygen vacancies, validating the two-site model. The kinetic parameters indicated that the conversion of cyclohexanol to cyclohexane was the fastest reaction step, and the demethoxylation pathway was favored over the demethylation on the Ru/TiO2 catalyst.

Resumen. Se propone un modelo cinético Langmuir-Hinshelwood para describir la reacción de hidrodesoxigenación de anisol utilizando un catalizador Ru/TiO2 en un reactor de flujo continuo de lecho fijo. Se evaluaron inicialmente las condiciones de operación, como la presión, temperatura y velocidad espacial, con el fin de asegurar que el sistema opere dentro del régimen cinético. El modelo considera la presencia de dos sitios catalíticos adyacentes: uno destinado a la adsorción disociativa del hidrógeno y otro para la adsorción y reacción tanto de anisol como de sus productos de reacción. El modelo mostró un buen ajuste con los datos experimentales, indicando una ruta preferencial hacia la desmetoxilación, que produce benceno, frente a la desmetilación, que favorece la formación de fenol. La caracterización del catalizador Ru/TiO2 mediante técnicas de XRD, TPR-H2, TPD-NH3 y XPS reveló la presencia de partículas de Ru0 altamente dispersas y sitios oxofílicos superficiales, incluidos sitios ácidos y vacantes de oxígeno, lo que valida el uso del modelo de dos sitios propuesto. Los parámetros cinéticos indicaron que la conversión de ciclohexanol a ciclohexano es el paso de reacción más rápido, y se favoreció la ruta de desmetoxilación sobre la desmetilación en presencia del catalizador Ru/TiO2.

Hydrogen Bonding Processes During Self-protonation of Natural α-hydroxyquinones
Authors: Armendáriz-Vidales Georgina , Hernandez-Perez Fidel , González-Bravo Felipe J. , Frontana Carlos 
Published: January 2025

The passage from non-substituted quinone to hydroquinone moieties involves the exchange of two-electron and two-protons, however, the presence of hydroxyl groups in the α position to the carbonyl group of the quinone induce a mechanistic change in which the quinone plays the role of electron acceptor and proton donor. This feature promotes a self-protonation mechanism which can be characterized in the framework of the ECE-DISP theory. However, when additional hydroxyl groups are contained in the quinone structure, hydrogen bonding becomes an additional competition factor that was studied in this work using a series of synthetic and natural quinones with different structures. The number of hydroxyl groups on the quinone structure was studied from the point of view of electrochemical mechanisms and descriptors of reactivity. Cyclic voltammetry, mechanistic simulation and electronic structure calculations were used as an approach to understand the interplay between electron transfer, proton transfer and hydrogen bonding association in α-hydroxyquinones.

Resumen. La conversión quinona-hidroquinona involucra el intercambio de dos electrones y dos protones; sin embargo, la presencia de grupos hidroxilo en la posición α respecto al carbonilo de la quinona, induce un cambio mecanístico en el cual el núcleo quinoide juega ahora el papel de acceptor electrónico y donador de protón. Esta característica promueve un mecanismo de autoprotonación que puede ser caracterizado mediante la teoría ECE-DISP. Sin embargo, cuando hay grupos hidroxilo adicionales dentro de la estructura quinoide, la formación de puentes de hidrógeno se convierte en una ruta competitiva adicional, la cual fue estudiada en este trabajo empleando una serie de compuestos sintéticos y naturales. El número de grupos hidroxilo y su influencia fueron estudiados desde el punto de vista de mecanismos electroquímicos y descriptores de reactividad. A través del uso de voltamperometría cíclica, simulación mecanística y cálculos de estructura electronica, se realizó una aproximación para comprender la interrelación entre la transferencia protónica, electrónica y la asociación a través de puentes de hidrógeno en α-hidroxiquinonas.

Proses pencucian dan peragian kedelai merupakan salah satu operasi yang merepresentasikan perlu adanya perbaikan karena beresiko menimbulkan masalah ergonomi yaitu cedera akibat postur kerja yang tidak optimal. Hal ini dikarenakan aktivitas operasi produksi sebagian besar dilakukan tanpa menggunakan alat bantu dan melakukan gerakan secara repetitif sehingga menambah parameter waktu pemrosesan dan masuk dalam pemborosan. Untuk mengevaluasi kondisi proses kerja ini, diperlukan pendekatan yang menggabungkan penilaian proses produksi dan ergonomi terhadap beban kerja fisik. Kuesioner Nordic Body Map (NBM) digunakan untuk mengetahui prevalensi cedera MSDs yang dialami dan memberikan informasi kondisi beban kerja yang tidak menguntungkan. Temuan menunjukan bahwa daerah yang paling sering terkena dampak adalah kaki, punggung, dan tangan. Selanjutnya, pengukuran sistem REBA assessment digunakan untuk menganalisis dan mengkategorikan urgensi kedalam empat tingkat perbaikan. Mesin pencuci peragi kedelai dikembangkan dan diteliti untuk meningkatkan produktivitas pekerja pada proses pencucian dan peragian kedelai. Peninjauan eksperimental dilaku¬kan dengan mengkombinasikan analisis efektifitas, kenyamanan dan efisiensi mesin pencuci peragi kedelai. Eksperimental dilakukan di UD.Tempe 85 dengan bahan uji berasal dari mitra. Pengambilan data penelitian efektifitas - efisiensi dilakukan sebanyak 4-5 replikasi dengan mengkomparasikan metode proses manual dan mesin pencuci peragi kedelai. Hasil penelitian menunjukan bahwa mesin pencuci peragi kedelai jauh lebih cepat daripada metode manual dalam mencuci maupun meragi kedelai dengan kapasitas 2x lipat dibanding hanya 30 kg/jam proses manual. Analisis kenyamanan REBA menunjukan level 1 sangat rendah terkena cedera dengan skor REBA 3 sedangkan metode pencucian peragian manual termasuk dalam level 4 memerlukan penerapan perubahan dengan skor REBA 11. Kelayakan penerapan mesin pencuci peragi kedelai ini direkomendasikan karena menekankan pentingnya risiko rendah dan produktivitas dalam penggunaannya.

Published: January 2025

Eloquent brain creates a challenge when resecting brain arteriovenous malformations (bAVMs). Here the authors present their technique of using subcortical motor mapping as an adjunct to increase safety during resection of a high-grade bAVM involving somatosensory cortex as well as cortical spinal tracts and visual tracts. After a bilateral craniotomy, they use direct cortical stimulation of the left motor cortex and subcortical stimulation using a suction stimulator to dynamically map motor tracts during the resection. They get within 3 mm of the corticospinal tracts by stimulation.

Post-verbal agreement and obligatory presence of particle to in Polish dual copula clauses
Authors: Jurczyk Rafał 
Published: January 2025

This paper addresses the obligatory particle to in Polish dual copula clauses (DCCs) with post-verbal agreement and two 3rd person nominative expressions with φ-feature(s) mismatch. It argues that to must be present because the syntax cannot successfully establish the φ-Agree relation between T and the post-verbal nominative expression (NPNOM2). Two crucial premises are adopted. One is Zeiljstra’s (2012) Upward Agree which requires i-features to c-command u-features and, hence, necessitates the closest NPNOM to T to SpecTP-move. The other is Vangsnes’s (2002) obligatory TP identification by the Tense- (provided by T) and φ-features (provided by NPNOM controlling agreement) to anchor the subject to the eventuality denoted by the complex predicate Pred’ [be NPNOM2] (Jurczyk 2021). The examination shows that T-NPNOM2 φ-Agree in DCCs under consideration cannot be established as SpecTP-movement of NPNOM2 is illegitimate; NPNOM2 if formally and syntactically part of Pred’ and is also farther from T than NPNOM1, the pre-verbal nominal expression. Consequently, T’s φ-features remain unvalued, which makes TP formally unidentified. However, since some of T’s NPNOM2-specified features are specified as those on NPNOM1, T attracts NPNOM1 to value them whereas features bearing NPNOM2’s specification get valued as default and lexicalised as the least-marked form in terms of feature specification (following Szucsich 2007), i.e., to[i-neut]. It is thus concluded that the obligatory presence of to is a means of formally identifying TP in case any of T’s NPNOM2-specified φ-features cannot be successfully valued by the T-NPNOM2 Agree relation.
