Published: August 2024

В работе исследован углеродсодержащий материал как сорбент для удаления фенола из водных растворов, который получали гидролизом рисовой шелухи гидроксидом натрия с последующей карбонизацией твердого остатка при 400°С в условиях недостатка кислорода. Образец имеет сложную слоисто-волокнистую структуру с порами разной формы и находится в рентгеноаморфном состоянии. Кинетические кривые показали, что сорбционное равновесие на ~ 85% достигается через 60 мин после начала сорбции, и подчиняется в большей степени модели псевдовторого порядка (R>0,9), что указывает на взаимодействие между сорбатом (фенолом) и функциональными группами сорбента. Изотерма адсорбции лучше всего описывается уравнением Дубинина-Астахова и относятся к физической адсорбции, которая определяется его пористой структурой.

In this work, a carbon-containing material was studied as a sorbent for removing phenol from aqueous solutions, which was obtained by hydrolysis of rice husks with sodium hydroxide followed by carbonation of the solid residue at 400°C under conditions of oxygen lack. The sample has a complex layered-fibrous structure with pores of different shapes and is in an X-ray amorphous state. Kinetic curves have shown that the sorption equilibrium is reached by ~ 85% 60 minutes after the start of sorption, and obeys to a greater extent the pseudo-second order model (R>0.9), which indicates the interaction between the sorbate (phenol) and the functional groups of the sorbent. The adsorption isotherm is best described by the Dubinin-Astakhov equation and refers to physical adsorption, which is determined by its porous structure.

Published: August 2024

Electrochemical ocean alkalinity enhancement (OAE) is a promising technology for negative carbon emissions, but the resulting dilute acid stream poses a disposal challenge. This study presents an innovative method to neutralize this acid using recycled concrete aggregates (RCA) while simultaneously producing high-quality aggregates for new construction. A rotary drum reactor facilitates the reaction by reducing the acid concentration from 0.5 M to 0.1 M HCl and lowering the RCA water absorption from 6.8% to 0.5-1%. The remaining 0.1 M acid is further neutralized to near-neutral pH by reaction with RCA fines. The effects of pre-carbonation on RCA and the scalability of this method are also discussed. Integrating waste concrete upcycling with electrochemical OAE has the potential to achieve hundreds of megatons of negative CO2 emissions annually, while diverting gigatons of construction and demolition waste from landfills, thus generating significant revenue through reduced disposal fees and the production of valuable aggregates.
Optimizing continuous monitoring sensor placement on oil and gas sites
Authors: Jia Meng , Sorensen Troy , Hammerling Dorit
Published: August 2024

We propose a generic, modular framework to optimize the placement of continuous monitoring sensors on oil and gas sites aiming to maximize the methane emissions detection efficiency. Our proposed framework substantially expands the problem scale compared to previous related studies and can be adapted for different objectives in sensor placement. This optimization framework is comprised of five steps: (1) simulate emission scenarios using site-specific wind and emission information; (2) set possible sensor locations under consideration of the site layout and any site-specific constraints; (3) simulate methane concentrations for each pair of emission scenario and possible sensor location; (4) determine emissions detection based on the site-specific simulated concentrations; and (5) select the best subset of sensor locations, under a given sensor budget, using genetic algorithms combined with Pareto optimization. We demonstrate the practicality and effectiveness of our framework through its application to an oil and gas emission testing facility with a large search space of possible sensor locations; a setting which is computationally infeasible to solve with commonly used mixed-integer linear programming formulations. Additionally, a case study illustrates the successful application of our algorithm to a real oil and gas site, showcasing its real-world applicability and effectiveness.

Authors: Chauhan Pankaj , Kumar Jaswant , Sharma Deepak , Hussain Yaseen , Solaim Solaim , Muskan Muskan , Changotra Avtar
Published: August 2024

Diazo compounds have extensively been investigated under light or metal-mediated conditions to carry out carbene-mediated transformations. In the search for novel reactivity, investigating these dinitrogen substrates under electrochemical conditions remained underexplored. Herein, we have explored diazo compounds under electrochemical conditions to establish a cascade sequence of thiolation/cyclization/reduction reactions. Electrolyzing styryl diazo imides and aryl thiols enables direct access to a single diastereoisomer of 2,5-pyrrolidine-dione-fused thiochromans in good yields under mild and metal-free conditions. Notably, a tunable reactivity was achieved via S-H insertion at the diazo center in slightly modified reaction conditions. Based on the experimental evidences, including the detection of key intermediates and computational studies, the mechanism for the electrochemical cascade reaction has also been established.

Given the last few years there have been many large earthquakes that have occurred in Indonesia. For example, the Aceh earthquake in 2004, the Yogyakarta earthquake in 2006, the Padang and Bengkulu earthquake in 2007. The earthquake caused a lot of damage to building structures. After conducting an in-depth study on this matter, that the large earthquake that occurred turned out to be due to the acceleration of the bedrock which was greater than the acceleration of the bedrock that had been determined in the SNI 03-1726-2012 earthquake map. Based on these findings, the earthquake map SNI 03-1726-2012 was deemed no longer suitable to be applied as a guideline for earthquake resistant structure planning. Because a new earthquake regulation appeared and was enforced, this resulted in the need for revision or review of existing buildings to be reviewed using the latest regulations. With the existence of the latest regulations (RSNI 03-1726-2019), all buildings planned with the old regulations (SNI 03-1726-2012) need an evaluation of the calculation of the earthquake effect of the old buildings against the latest regulations. Therefore, after conducting research by comparing the structural behavior between the two regulations in the USM psychology faculty lecture building in the T building by comparing SNI 03-1726-2012 with SNI 03-1726-2019, the comparison results obtained in the column of longitudinal reinforcement requirements experienced an increase of 50% and the need for shear reinforcement has increased by 12.04%, while for the comparison of beams the need for longitudinal reinforcement has increased in field reinforcement by 25%, and the shear reinforcement has increased by 25%

Job rotation is a move from one room to another but still within the same scope of work. Rotation is carried out as a way to improve the quality of nursing services, to refresh and prevent boredom, to meet the needs of nursing staff in the room, and to improve nursing skills. At Martha Friska Multatuli Hospital, rotation has been implemented since 2020. This research aims to determine the relationship between rotation and the performance of nurses at Martha Friska Multatuli Hospital. This research method uses descriptive correlation with a cross sectional design. The sample size in this study was 71 respondents with a sampling technique using total sampling. Data analysis in this study used the Spearman's Rank correlation coefficient test. The research results showed that the majority of nurses stated that the rotation at Martha Friska Multatuli Hospital was a fairly good rotation, 42 respondents (59.2%) and it was also known that the majority of nurses' performance was in the good category, 58 respondents (81.7%). The results of statistical tests using the Spearman rank test obtained an r-value of 0.255 with a Ï-value of 0.032. This shows that there is a correlation or positive relationship between rotation and the performance of nurses at Martha Friska Multatuli Hospital with a low level of relationship.Â Keywords: Peformance, Rotation
The Derivation and Characterisation of Bovine Expanded Potential Stem Cells
Authors:   , Scully Liam
Published: August 2024

Embryonic stem cells were first derived from the embryo of a mouse in 1981. They are characterised by their ability to eternally self-renew in proper conditions in cell culture, and their ability to be directed to differentiate into all adult tissue types. In the last 40 years embryonic stem cells have been derived in mice, then humans and more recently in livestock animals including cattle, pigs, and horses. Stem cells have been used in a wide range of research areas, with more recent developments of 3D cell cultures and organoids being used in complex modelling of diseases like cancer and Covid-19. This thesis explores a new method for the derivation of expanded potential stem cells first used to derive mouse expanded potential stem cells, and subsequently applied to derive human and porcine expanded potential stem cells. Hatched bovine blastocyst-stage embryos were plated on mouse embryonic fibroblast feeders using a chemically defined media, which promoted outgrowth of the inner cell mass. Outgrowths were able to be passaged twice, surviving up to 20 days. Immunohistochemistry and alkaline phosphatase staining showed limited expression of pluripotency related genes, and no expression of trophectoderm genes. However, after passaging, much of this expression was lost. While the general principles of the process show promise, further research is needed to optimise the process of derivation and improve passaging quality to properly derive a bovine embryonic stem cell line.

Authors: Wang Zhe
Published: August 2024

Hearing loss is a significant barrier to academic achievement, with hearing-impaired (HI) individuals often facing challenges in speech recognition, language development, and social interactions. Lip-reading, a crucial skill for HI individuals, is essential for effective communication and learning. However, the COVID-19 pandemic has exacerbated the challenges faced by HI individuals, with the face masks hindering lip-reading. This literature review explores the relationship between hearing loss and academic achievement, highlighting the importance of lip-reading and the potential of artificial intelligence (AI) techniques in mitigating these challenges. The introduction of Voice-to-Text (VtT) technology, which provides real-time text captions, can significantly improve speech recognition and academic performance for HI students. AI models, such as Hidden Markov models and Transformer models, can enhance the accuracy and robustness of VtT technology in diverse educational settings. Furthermore, VtT technology can facilitate better teacher-student interactions, provide transcripts of lectures and classroom discussions, and bridge the gap in standardized testing performance between HI and hearing students. While challenges and limitations exist, the successful implementation of VtT technology can promote inclusive education and enhance academic achievement. Future research directions include popularizing VtT technology, addressing technological barriers, and customizing VtT systems to cater to individual needs.

Layoff Factors Analysis: Evidence from 2021 China General Social Survey
Authors: Ji Zheng , Zhao Chongtao
Published: August 2024

This paper analyzes factors that explain company layoffs, given the individual layoff data in 2021, China. Using the Probit regression model, we find that gender inequality exists in layoffs, an employee’s work experience becomes less critical in the company’s layoff decisions, and how an employee’s health reasons affect work affects its probability of being laid off. Since we consider a significant endogeneity issue with education, using parents’ education as an instrumental variable suggests that political status cannot be a significant advantage for employees to lower the chance of being laid off. Moreover, evidence implies that policymakers encouraging the pursuit of higher educational degrees can foster stability in the labor market.
