Published: August 2024

The chemical reaction of cement and water produces compounds that are alkaline and react with various acids so that they can reduce the quality of concrete. To minimize this effect, pozzolanic materials need to be added. Organic pozzolan materials such as coffee shell ash waste can be used as material for making lightweight foam concrete which can be applied to non-structural buildings such as lightweight bricks. This research was conducted to see the effect of coffee shell ash substitution for cement on the properties of fresh concrete and the mechanical properties of lightweight foam concrete and to find the most optimal substitution composition for coffee shell ash for cement as well as lightweight foam concrete with FAS 0.5. Substitution of coffee shell ash for cement weight was carried out with variations of 0% BBN, 5% BBAAK1, 10% BBAAK2, and 15% BBAAK3 using 1% superplasticizer additive. The test object used is a cylinder with dimensions of 15 cm x 30 cm. The number of test objects used was 24 pieces. Tests for compressive strength and split tensile strength were carried out at the age of 28 days. The results of compressive strength tests carried out at 28 days for the lightweight foam concrete variations BBN, BBAAK 1, BBAAK 2 and BBAAK 3 were respectively 15.29 MPa, 12.21 MPa, 18.29 MPa and 19.52 MPa. The greater showing variation in the percentage of coffee shell ash substitution used, the greater the resulting compressive strength and split tensile strength values. This is because Sikament NN also plays a role in increasing the compressive strength of concrete

Hydrogen: Challenges and Solutions for Safe and Effective Implementation
Authors: Melo Carlos Vital Paixão de , Brandim Ayrton de Sá , Alvarez Hubert. A. A.
Published: August 2024

Hydrogen represents a promising energy source due to its unique properties, but its safe and effective implementation faces numerous challenges. Its low activation energy facilitates rapid and efficient reactions, reducing energy consumption and promoting the production of clean fuels. However, hydrogen also presents significant risks due to its wide flammability range and high diffusion rate, increasing the risk of explosions, fires, and leaks. To address these challenges, it is essential to develop and implement rigorous safety measures, specialized infrastructure, and advanced technologies. Emerging technologies such as water electrolysis and solid oxide fuel cells and proton exchange membrane (PEM) cells offer promising solutions for the efficient production and use of green hydrogen, although they face obstacles such as competition with other renewable energy sources, price fluctuations, and the need for robust infrastructure. Hydrogen storage and distribution require innovative solutions to overcome issues of volume, energy density, and leak risk. Storage technologies include high-pressure tanks and cryogenic methods, while distribution can be done through pipeline networks, tanker trucks, and maritime transport. Additionally, hydrogen injection into natural gas networks and underground storage are explored strategies to enhance the viability and safety of hydrogen as an energy source. In summary, the successful implementation of hydrogen as a safe and effective energy solution requires a combination of technological advances, infrastructure development, and supportive policies. It is crucial to balance its energy efficiency and emission reduction benefits with operational and environmental challenges through the adoption of robust regulations and the promotion of technological innovations.

Persistence with medical glaucoma therapy in newly diagnosed patients
Authors: Menino Joana , Camacho Pedro , Coelho Andre
Published: August 2024

Background: Monotherapy, age, and side effects are significant risk factors for the discontinuation of antiglaucoma therapy. Long-term therapy persistence is crucial for slowing disease progression and preventing irreversible blindness. Therefore, it is essential to identify patients at higher risk of discontinuation. In this study, we aimed to evaluate the real-world persistence of antiglaucoma therapy in patients diagnosed with glaucoma in the primary healthcare units of the Lisbon and Tagus Valley regions.
Methods: We conducted a retrospective longitudinal study by collecting data from the prescription records of new antiglaucoma drug users diagnosed with glaucoma between 2012 and 2013 in the Primary Health Care Units of the Lisbon and Tagus Valley Region. These patients were followed over 3 years. Therapy persistence was measured as the proportion of patients remaining on any antiglaucoma drug, regardless of any modifications or switching of drugs over time. Persistence was assessed at three time points: the end of the first, second, and third years of the observation period.
Results: A total of 2138 patients treated using new antiglaucoma drugs (867 [40.6%] male patients; 1271 [59.4%] female patients) were included in the study. Over the observation period, the overall persistence rate decreased from 91.9% (n = 1965) in the first year to 67.3% (n = 1439) in the third year. Older patients (greater than or equal to 65 years) showed higher persistence rates, although there was a decrease over the 3-year follow-up period (from 1481 [92.7%] to 1124 [70.4%]). Additionally, participants initially treated with monotherapy showed higher persistence rates, ranging from 92.4% (n = 1186) in the first year to 70.2% (n = 901) in the third year.
Conclusions: The findings highlight the importance of patient follow-up over time, as almost one in three new antiglaucoma therapy users completely discontinued treatment, potentially risking disease progression. This could be mitigated with proper use of these drugs. Further studies should utilize recent health information systems to explore the impact of medication adherence and persistence on the functional and structural outcomes in patients with glaucoma.
Corneal and anterior segment parameters in patients with clinically unilateral pseudoexfoliation syndrome
Authors: Karmiris Efthymios , Machairoudia Genovefa , Roussou Aikaterini , Tsiogka Anastasia , Chalkiadaki Evangelia
Published: August 2024

Background: Pseudoexfoliation syndrome (PES) is an age-related systemic condition that predominantly affects ocular structures and is characterized by the deposition of material on the lens, ciliary body, zonules, corneal endothelium, iris, and pupillary margin. We compared the corneal endothelial morphology, anterior segment parameters, corneal densitometry, and corneal topographic characteristics between the clinically affected and apparently normal fellow eyes of patients with clinically unilateral PES.
Methods: This was a comparative, cross-sectional study of 34 patients with clinically unilateral PES. The anterior segment was examined using a Scheimpflug imaging system, and the corneal endothelium was assessed using a noncontact specular microscope. Corneal endothelial cell density, polymegathism, and pleomorphism were assessed using the specular microscope. Furthermore, the Scheimpflug camera was used to measure the corneal power of the flat and steep axis, mean corneal power, maximum keratometry, anterior chamber angle, anterior chamber depth, anterior chamber volume, corneal volume, and the corneal thickness at the apex point, center of the pupil, and the thinnest point. Corneal densitometry was evaluated at two concentric zones (0–2 mm and 0–12 mm).
Results: In total, 68 eyes from 34 patients were ultimately included in the study. The mean (standard deviation) age of the patients was 73.38 (8.75) years (range: 50–87 years). Among the included patients, 17 (50%) were male and 17 (50%) were female. The anterior segment parameters did not significantly differ between eyes with PES and their clinically unaffected fellow eyes (all P > 0.05). Similarly, no statistically significant difference was observed in corneal endothelial morphology (all P > 0.05).
Conclusions: Our measured parameters do not differ between the clinically affected eye and the clinically unaffected fellow eye. This supports the theory that PES is a bilateral disorder. Considering the variety of complications associated with PES, bilateral involvement should be assumed in the clinical and surgical management of patients with clinically unilateral PES. In the future, new research could increase our understanding of this syndrome.

The technological processes mechanised with the help of this system are used in a wide variety of industries. The practice of engineering calculations demonstrates that in many cases the links of transmission mechanisms are the most pliable, directly transmitting dynamic loads. Consequently, the modelling of transmission mechanisms in mechanical systems, taking into account both kinematic and dynamic characteristics, isa highly relevant area of study. This research presents a set of methods and techniques for determining the kinematic and dynamic characteristics of mechanical systems. It is shown that geometric characteristics significantly affect the dynamics of the mechanical system as a whole. The Lagrangian equation of the second kind is employed in the formulation of the equation of motion of mechanical systems. A crucial phase in the modelling of mechanical systems is the assessment of the stress-strain state of the supporting metallic structure. Autodesk Inventor software was utilised to ascertain the stress-strain state and safety factor of the mechanical system.

Mathematics is one of the important subjects. Mathematics is also a subject that is difficult to understand. Understanding concepts is the most important part of learning mathematics, meaning that in studying mathematics students must first understand mathematical concepts in order to be able to solve problems and be able to apply this learning in the real world.
Based on direct observations and interviews with grade 6 teachers at SD Negeri 02 Getas, teachers have difficulties in the theme of lesson 3 about "Building Space" with basic competencies; 1) identify & compare geometric shapes; 2) calculating the surface area of the geometric shape; 3) calculate the volume of the geometric shape. This is what drives the need to develop game-based mathematics learning media.
This game was created using Construct2 software as a 2D video game engine. The method used in this study is the MDLC (Multimedia Development Life Cycle) method.

This research aims to predict customer churn in a telecommunications company using Logistic Regression (LR) and Gradient Boosting Classifier (GBC) algorithms. Customer churn poses a significant challenge as acquiring new customers is costlier than retaining existing ones. The dataset from Kaggle comprises 7043 records and 21 attributes. The process includes data pre-processing, cleaning, transformation, and normalization using a Min-Max Scaler. The data is split into features (X) and target (y), then divided into training and testing sets with an 80:20 ratio. Both models were trained and evaluated using a confusion matrix. Results show that the GBC model outperforms the LR model, with an accuracy of 83% compared to LR's 81%. This study demonstrates the effectiveness of GBC in predicting customer churn.
