A critical review of experimental research on the durability of cement modified with partial steel slag replacement
Authors: Aditya Prakash Chauhan , Vishal Chauhan , Gaurav Maurya , Praveen Kumar Yadav
Published: August 2024

The construction industry is looking for sustainable and cost-effective alternatives to conventional building materials. As the world faces increasing environmental challenges, the need for greener construction practices has become more urgent. Cement production is known for its high energy consumption and significant carbon dioxide emissions. Therefore, it is essential to find ways to reduce the environmental impact of cement production and use. One promising area of research is the use of industrial byproducts such as steel slag to partially replace cement in concrete. The use of these by-products not only solves the problem of waste disposal but also provides a sustainable solution to improve the properties of building materials. When mixed with cement, steel slag participates in pozzolanic reactions, in which reactive silica from the slag reacts with calcium hydroxide, produced during the hydration of cement, to form calcium silicate hydrate gel (CSH). This CSH gel is responsible for the strength and durability of concrete. Incorporating steel slag can improve the mechanical properties of concrete, including compressive, flexural, and tensile strength. In addition, steel slag can improve the durability properties of concrete, such as resistance to chemical attack, reduced permeability, and increased resistance to physical and chemical degradation over time. This paper investigates the durability properties of cement when partially replaced by steel slag, focusing on various aspects of durability, including resistance to chemical attack, mechanical strength, and long-term performance under various environmental conditions. The study includes a comprehensive experimental program designed to evaluate the impact of steel slag on the durability of concrete through a series of tests and analyses.
Optimising a Spatial Gene Expression Protocol to Track Progenitor to Theca Cell Differentiation In Situ.
Authors:   , Young Michaela
Published: August 2024

The theca, a highly specialised stromal cell layer that surrounds ovarian follicles, first appears at the secondary stage of ovarian follicle development. While the role of the theca in folliculogenesis is well understood, the spatiotemporal dynamics governing theca cell differentiation are yet to be fully elucidated. Spatial transcriptomics offers a unique insight into the spatiotemporal dynamics of the molecular processes that occur during cell differentiation by capturing mRNA expression patterns within tissues, maintaining their spatial context. The overall objective of this thesis was to optimise a protocol to perform spatial transcriptomics in mouse ovarian tissue. This contributes to a wider project which aims to track the progenitor to differentiated theca cell transition in situ using a mouse model. I refined protocols for collecting ovaries, and various histological techniques (including protocols for freezing, embedding and cryosectioning) that prioritised maintaining the integrity and morphology of ovarian tissue for imaging, while still allowing for the recovery of high-quality RNA from the same sample. As a result, I was able to validate this protocol by collecting and preparing ovarian tissues, using the optimised sample preparation protocol, perform tissue-specific permeabilization optimisation for the STOmics Stereo-seq Transcriptomics kit, and contribute to the final spatial transcriptomic experiment. I prepared a fresh-frozen tissue block containing four ovaries from four mice (n=4), which was of sufficient quality (RNA Integrity Number (RIN) 7.4 ± 0.1) to proceed with the experiment. This sample consistently passed all DNA concentration and fragment size quality control checks throughout the experiment, indicating that the optimised tissue preparation protocol was successful in generating a high quality (both in terms of morphology and RNA quality) sample which was used to prepare the final RNA-seq library. This thesis serves as a valuable resource for future studies using spatial transcriptomics to investigate cellular differentiation within the ovary.

Objective: This study aims to evaluate the application value of biological monitoring and different types of chemical indicator cards in batch monitoring of hydrogen peroxide low-temperature plasma sterilization. The goal is to standardize the selection of loading conditions for this sterilization method and avoid positive biological monitoring results. Methods: Physical monitoring, Class I chemical indicator card monitoring, Class IV chemical indicator card monitoring, and biological monitoring were used to monitor the hydrogen peroxide low-temperature plasma sterilization process. The sterilization effect on instruments inside the Johnson & Johnson 100S plasma sterilizer was monitored and the qualification of various monitoring methods was compared. Results: The comparison showed that when non-standard or adsorption-prone packaging materials were used, the interception rate of biological monitoring and Class IV chemical indicator cards was significantly higher than that of physical monitoring and Class I chemical indicator cards. These methods more intuitively and effectively detected sterilization failures. Conclusion: Biological monitoring and Class IV chemical indicator cards are safe, fast, accurate, and easy to interpret in hydrogen peroxide low-temperature plasma sterilization, especially for monitoring instruments inside packages. They provide a reliable basis for the release of sterilized instrument packages. Identifying the reasons for positive biological monitoring results in hydrogen peroxide low-temperature plasma sterilization and taking effective measures promptly can minimize associated risks.

Published: August 2024

Learning physics in high school has a goal students can master physics concepts and have a confident attitude. Currently, students' comprehension of concepts is still lacking, considering the mindsets and attitudes of students who have not demonstrated a positive approach toward learning physics. It is necessary to analyze the students' conceptual comprehension, attitudes toward studying physics, and the link between conceptual understanding and student attitudes. This research includes descriptive research with a qualitative approach. The population of this study is all students of class XII MIPA SMAN Batusangkar and a sample of 172 students. This study used a purposive sampling technique. The instruments used are four tier multiplechoice diagnostic tests and attitude questionnaires. Overall, the research result at SMAN Batusangkar discovered that pupils' conceptual grasp was still lacking, so there is a misconception of 41.28% on the material of temperature and heat. Students' attitudes towards learning physics as a whole, they have shown a good attitude towards learning physics, which is in the good category of 68.92%. Concept understanding and students' attitudes towards learning physics have a moderate relationship. Correlation concepts understanding with student attitudes shows that student attitudes can influence concepts understanding, causing unsatisfactory physics learning outcomes.

It is very important for students to understand the concept of simple harmonic motion, such as a mathematical pendulum. Students need an experiment tool on mathematical pendulums that is capable of providing measurement results of various physical quantities of mathematical pendulums accurately and precisely. This research aims to (1) describe the specifications of an Arduino-based mathematical pendulum experiment tool, (2) describe the results of measurements of acceleration due to gravity, and (3) describe the effect of changes in deviation on the period at small angles. This research used the experiment method. The research results showed that (1) the Arduino-based mathematical pendulum experiment device is equipped with an HC-SR04 ultrasonic sensor to measure the length of the string and an FC-51 infrared sensor to measure the period with a precision of 94.9% and accuracy of 99%, (2) the average result of acceleration due to gravity measurements at various string length was (9.72 ± 0.19) m/s2,and (3) the mathematical pendulum period between angles of 1-13 degrees did not show a significant difference, showing that at small angles, the oscillation period is not affected by deviation.

Abstrak— berakhirnya pandemi covid-19 berimbas pada monitoring penggunan masker yang semakin diabaikan, meskipun memakai masker dapat mengurangi resiko penularan. Memanfaatkan Artificial Intelegence untuk melakukan object detection menjadi salah satu solusi agar monitoring tetap dapat dilaksanakan, salah satunya dengan metode Single Shoot Multibox Detector (SSD) [1]. Arsitektur SSD memiliki 3 layer utama yaitu, base network, extra convolutional feature layers, dan convolutional predictor layer. Convolutional predictor layer menghasilkan 8732 deteksi untuk tiap kelas, dari hasil kombinasi base network dan extra convolutional feature layer dengan default boxes. Pada penilitian ini, arsitektur SSD dilakukan modifikasi (SSD v2) pada convolutional predictor layer yang hanya mendapat input dari extra convolutional feature layers, sehingga deteksi yang dihasilkan berkurang menjadi 790 deteksi. Dari hasil training dan testing dalam melakukan deteksi masker, SSD v2 mempunyai mAP sebesar 87,23%, sedangkan SSD mempunyai mAP sebesar 92,79%. Akan tetapi,  SSD v2 memiliki nilai loss yang lebih kecil  yaitu sebesar 1,03, sedangkan SSD v2 memiliki nilai loss 1,39.
