In recent years, brakes emission tests have become increasingly standardized to meet progressively stricter intra and inter laboratory reproducibility requirements. In particular, following the recent EURO 7 regulation proposal, WLTP-Brake cycle has surged as EU standard braking sequence to determine emission factors of investigated brake systems. Furthermore, the UN GTR (United Nations Global Technical Regulation) on Laboratory Measurement of Brake Emissions for Light-Duty Vehicles collects all the information needed to perform emission tests in laboratory. This includes design specifications for the testing platforms as well as the typology and configuration of measuring instruments. Notably, laboratory emission tests are also increasingly used to collect particulates for chemical characterization, since the compositional information is crucial to: i) provide correct assessment of their toxicological and environmental behavior; and ii) better understand tribological and emission mechanisms. Therefore, this work specifically aims at investigating the topic of the inter laboratory reproducibility of physico-chemical properties in particulates generated by the same friction couple when collected during emission tests carried out on different testing platforms. In particular, the contribution focuses on the comparison of PM10 emissions generated by three different friction couples (i.e., ECE R90 Low Steel, NAO and Inorganic-bound friction materials coupled against grey cast iron brake discs) during sets of WLTP tests performed at two different facilities. More in detail, a wide physico-chemical characterization performed by Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDXS) and X-Ray Diffraction (XRD) analysis is used to unveil the inter laboratory reproducibility of both the particle size distribution and the chemical composition of corresponding twin particulates collected at the two testing laboratories. The reported results will provide useful insights regarding the variability level to be currently expected in selected physico-chemical properties of non-exhaust emissions from brakes when collected in different testing facilities.
Transfer Learning-Based Neural Network for Natural Frequency Prediction of Linear Dynamic Systems
Authors: Mammily Sreejesh
Published: November 2023

The prediction of natural frequencies is a crucial aspect of engineering design and analysis. Traditional methods involve finite element analysis (FEA) which is a standard method for calculating natural frequencies of dynamic systems. For each design variant, FEA calculation can be time-consuming and computationally expensive. In this study, we propose a novel method for predicting the natural frequencies of design variants using transfer learning and artificial neural networks (ANN).

The proposed method involves the use of FEA to generate the stiffness and mass matrices of the brake disc, which are then used as inputs to the neural network. However, the prediction can become tedious when there is a change in the design. To address this, we employ transfer learning followed by linear regression using a design variant of the previous structure as test data. The neural network learns through transfer learning and fine-tunes its outputs using regression for final frequency prediction.

The proposed approach can predict the natural frequencies of new structures efficiently without compromising the quality of the outcome, even when the degree of freedom changes due to design alterations. The effectiveness of this method is demonstrated by calculating frequencies of brake disc with different material property, and the results are compared with FEA to measure its accuracy. The results indicate that this method can accurately predict the natural frequencies of new design variants with high prediction accuracy and computational efficiency. This method has potential applications in engineering design and analysis, especially for structures that require iterations to finalize design and where there is a need to calculate the dynamic characteristics of the system.

Published: November 2023

Friction in tribological systems can lead to significant energy consumption and wear. While there are several dissipation mechanisms in the frictional boundary layer, the role of chemical processes is not fully understood. The aim of this study is to investigate the influence of chemical reactions on the tribological behavior of sliding friction pairs. In order to carry out initial analyses, minimal mixtures with a few simple components and epoxy resin as a binder are developed, produced and used. A series of experiments are performed on a pin-on-disc tribometer with different minimal mixtures. Temperature and friction coefficient are measured throughout the friction process, and the rubbed surface of the samples is measured in situ. Three types of chemically inert minimal mixtures are developed in the first phase of the experiment. In the second phase of the experiment, copper powder is added to all minimal mixtures to study the influence of copper oxidation as the main chemical reaction. The tribometer measurement results show that the addition of copper has little effect on fine alumina samples and increases the friction coefficient and average wear volume of coarse alumina samples. In particular, the greater the amount of copper added to the mixtures, the greater the effect of copper and the more unstable the friction behavior of the coarse alumina samples. Following the tribometer measurements, the samples are also analyzed using energy dispersive X-ray spectroscopy (EDX) and scanning electron microscopy (SEM) to investigate the changes in the mixtures after the addition of copper. Initial chemical analysis results show that the coarse alumina samples with a certain amount of copper in them have more plateau-like patches formed in the boundary layer. These patches are mainly caused by the oxidation of iron coming from the disk during the measurement. Our results contribute to a better methodology for the study of tribochemical processes with predefined minimum mixtures in frictional contacts and to a better understanding of the role of tribochemical processes in the boundary layer dynamics, and can aid in the development of simulation tools.

Wild garlic (Allium ursinum) is a widespread perennial herbaceous plant that has wide therapeutic applications and it is used as well as food. Natural preparations based on wild garlic have been used for gastrointestinal tract disorders, as antioxidants, antihypertensive, hypolipidemic agents, etc. Nevertheless, the data related to the effects of chronic wild garlic extract consumption on systemic redox state in hypertensive animals is yet to be understood. Therefore, the main goal of this study was to examine the effects of a three-week application of ethanolic extract from wild garlic on oxidative stress markers in spontaneously hypertensive rats. This was an experimental study conducted in 20 spontaneously hypertensive Wistar kyoto rats divided into two groups: CTRL group – control untreated rats and wild garlic group – rats treated for three weeks with wild garlic ethanol extract once daily per os (100 mg/kg). After the accomplishment of the treatment protocol, animals were sacrificed, and blood samples were taken for determination of the levels of pro-oxidants and the activity of antioxidant enzymes. Our results indicate that there was a significant reduction in almost all of the measured pro-oxidants and an increase in antioxidant enzyme activity in rats treated with wild garlic extract compared to untreated rats. Ethanol extract from wild garlic showed promising antioxidant potential in hypertensive conditions, however, future studies are necessary in order to reveal the full therapeutic potential of this plant species in various cardiovascular disorders.

Hydride formation in metals is a widely studied and applied phenomenon necessary to transition to clean energy solutions and various technological applications. We focus on three perspective applications of these materials, namely near-ambient hydrogen storage, hydrogen storage compressor materials, and alkali metal conversion electrodes, to demonstrate acceleration in the research achieved by utilizing a data-driven approach. Graph neural network was developed using a transfer learning approach from the MEGNet model and data related to the thermodynamics of hydride formation obtained in experimental work. Based on the crystal structure and composition as input features, we apply the MetalHydrideEnth model developed in our previous work to predict hydride formation enthalpy in intermetallic compounds. In this work, we focus on demonstrating how this approach, combined with available crystal information obtained from density functional theory calculations, can be applied for fast and extensive searches of novel metal hydride materials, having in mind the above-listed applications.

Rho-associated coiled-coil kinases (ROCKs) are involved in essential cellular functions such as adhesion, contraction, motility, proliferation, and cell survival/apoptosis. Four ROCK inhibitors have already been approved by the FDA and are used to treat glaucoma (ripasudil and netarsudil), cerebral vasospasm (fasudil), and graft-versus-host disease (belumosudil). Recent studies have focused on exploring the role of ROCK kinase inhibitors in cancer treatment and the development of new ROCK inhibitors. The main objective of this study was to identify critical structural features relevant to the inhibition of ROCK1 using a ligand-based 3D-QSAR (3D quantitative structure-activity relationship) method. The 3D-QSAR model for ROCK1 was created and validated using internal and external validation parameters (R2, Q2, R2pred, rm 2, r/2m, rm̅̅2̅ and ∆r2m). The main structural features that correlate with the inhibition of ROCK1 were identified (e.g., heterocycle with hydrogen donor group like nitrogen atom) and further structural modifications of the ROCK1 inhibitors that contribute to increased activity were proposed (removal of the amino group of the oxadiazole, modification of the substituents of the phenyl ring).

Overexpression of Rho-associated protein kinases has been associated with various diseases, including tumors. None of the approved ROCK inhibitors are used for cancer treatment. However, some of them have been shown to have anti-tumor potential. The main objective of this study was to develop novel ROCK1 inhibitors using the structure-based method, molecular docking, and prediction of pharmacokinetic properties using the ADMET predictor. The key interactions that strongly correlate with the activity of ROCK1 inhibitors are hydrogen bonds between amino acid residues Met156, Glu154 and the hinge region of the inhibitors, indicating possible structural changes in the hinge region of studied compounds. On the other hand, the lack of interactions between 1,3-benzoxadiol moiety and the enzyme presents a promising approach for further structural modifications in order to design more effective ROCK1 inhibitors. All the important interactions between the developed ROCK1 inhibitors and the binding site of the enzyme were established. They also showed acceptable pharmacokinetic properties and could be further used for synthesis and evaluation by various biological assays.

In treating atherosclerosis and dyslipidemia, peroxisome proliferator-activated receptor alpha (PPARα) has been recognized as an interesting drug target. It is a ligand-activated transcriptional factor that controls genes involved in lipid metabolism regulation. The discovery of natural PPARα agonists may open new perspectives in its targeting. For several terpenoid molecules, it has been shown that they potentially activate PPARα. Linalool is a terpenoide molecule for which the PPARα antagonistic effect has been demonstrated in vivo. Here, we focused on searching for new terpenoid PPARα agonist candidates by proposing a simple theoretical criterion for fast virtual screening of TeroKit database. After in silico screening by using the EIIP/AQVN filter and through filtering of candidate compounds by ligand based virtual screening, natural monoterpenoid alcohol geraniol was selected as a promising candidate. Further, molecular docking was conducted to investigate its potential activation mechanisms, along with the reference molecule linalool. Despite observing low binding energies, the molecular docking results revealed potential insights into activation mechanisms of geraniol as well as reference molecule linalool.

Published: November 2023

Semakin banyaknya jumlah karyawan di Hotel terutama bagian housekeeping maka keanekaragaman karyawan juga semakin kompleks sehingga sulit untuk memilih karyawan housekeeping terbaik. Selama ini pemilihan housekeeping terbaik diputuskan oleh seorang manajer melalui pemilihan terhadap housekeeping secara langsung tanpa ada penilaian berdasarkan nilai. Terkadang pemilihan yang didilakukan cenderung bersifat subjektif sehingga sering terjadi kesalahpahaman antar sesama housekeeping. Selain itu, waktu yang diperlukan untuk mengambil keputusan tersebut kurang efektif. Oleh sebab itu, perlu adanya suatu Analisa Perbandingan, sehingga dapat mempersingkat waktu penyeleksian serta meningkatkan kualitas dalam menentukan karyawan terbaik. Analisa perbandingan pemilihan karyawan housekeeping terbaik menggunakan metode Moora dan Waspas berbasis pembobotan Entropy berdasarkan kriteria dan bobot yang telah ditentukan. Kriteria tersebut adalah kerapian, kebersihan, tata krama, kedisiplinan dan kerja sama. Moora dan Waspas berbasis pembobotan Entropy dipilih karena mampu menyeksi alternatif terbaik dari sejumlah alternatif.

Published: November 2023

The purpose of this study was to look at the impact of credit risk management on the financial performance of a few Kenyan microfinance firms. The study's approach was a descriptive survey research design and a panel data analysis technique. The study comprised credit managers from all 52 Kenyan microfinance institutions registered in the Association of Microfinance Institutions in Kenya (AMFI) database. The study included all of the institutions that were targeted. The questionnaire, which had previously been tested on local microfinance banks in Kakamega County, was used to collect data. Data analysis included regression analysis and correlation. Throughout the data collection process, the researcher observed integrity. Tables were used to present the study's findings. According to the model summary, credit risk management accounts for 49.1% of the variance in the financial performance of Kenyan MFIs, while other factors not included in the study model account for the remaining 50.9%. With a p-value of 0.01 that is statistically significant. Multiple linear regression analysis revealed that a one-unit change in credit risk management resulted in a significant improvement of 0.672 units in microfinance institution performance (= 0.672 (0.087); at p.01). The study found that prudent and effective credit risk management boosts net profit margins, return on capital invested, and cash flow. The study adds to existing theories by emphasizing the importance of credit risk management in microfinance, lays the groundwork for future research, and advises Kenyan microfinance organizations to invest in efficient credit risk management to improve their financial performance. The report also suggests that studies on Savings and Credit Cooperative Societies (SACCOs) be conducted to compare study findings and that the Association of Microfinance Institutions do studies on non-registered microfinance across the country.

Published: November 2023

Hypoxia-inducible factor-1 alpha (HIF-1α) is a transcription factor that plays a crucial role in cellular responses to hypoxia, such as in the development of intimal hyperplasia, a common complication in arteriovenous fistula (AVF) creation. While the application of umbilical cord mesenchymal stem cells (UC-MSCs) has shown promise in various regenerative medicine applications, including tissue repair and angiogenesis, the effect of UC-MSCs on HIF-1α level in the AVF has not been tested. Therefore, the aim of this study was to evaluate the effect of UC-MSCs administration on HIF-1α levels in the AVF animal model. An experimental study was conducted on 28 local male rabbits (Lepus domestica) using a post-test-only design. The rabbits were divided randomly into four groups: normal rabbit group (negative control), placebo-treated AVF rabbit group (positive control), AVF rabbits treated with in-situ UC-MSCs injection (one dose, 106 UC-MSCs/kg body weight), and AVF rabbits treated with intravenous UC-MSCs (one dose, 106 UC-MSCs/kg body weight (BW). HIF-1α level was measured using ELISA method after 28 days post- treatment. All data were analyzed using the one-way analysis of variance (ANOVA) and continued with the Duncan’s post-hoc test. The data indicated that the levels of HIF-1α were different among all four groups (p<0.001). The post-hoc analysis revealed that the HIF-1α levels in both UC-MSC treated groups were significantly lower compared to untreated AVF rabbits(p<0.05). This study suggests that UC-MSCs could be a promising therapy to prevent and reduce intimal hyperplasia in AVF.

Published: November 2023

Climate change is already an evident reality and an issue discussed globally. Natural and water resources are declining in most basins, sea levels are rising; and even if it is possible to reduce the emissions of greenhouse gases (GHG) that cause climate change, and thus avoid its most serious consequences, the negative trends will continue in the coming decades due to the inertia of the climate system (UN 2022). Today, no country is free from the bio-physical impacts of climate change; additional costs are also generated, with both the most vulnerable people and ecosystems being most affected. Adaptation is a top priority for developing countries, including more resilient agricultural practices and migration to safer places. The mitigation actions that the Member States of the United Nations have committed to undertake are not enough to achieve the reduction in greenhouse gases necessary for climate stabilization. So, to achieve climate adaptation the climate costs and the management of sustainable and resilient development require an enormous number of new resources.

En este estudio, se aborda la optimización de elementos cruciales en el proceso de producción de helado de crema, un producto alimenticio sometido a normativas rigurosas en cuanto a higiene y edulcoración. Este producto se obtiene a partir de una emulsión de grasas y proteínas, y puede incluir otros ingredientes y aditivos que estén permitidos según lo establecido en la Norma Técnica Colombiana NTC 1239. En lugar de emplear experimentos factoriales tradicionales, se utiliza un enfoque basado en el diseño de experimentos de mezcla con el objetivo principal de encontrar la formulación que maximice la deseabilidad global del producto final. El proceso comienza con la estandarización de variables y el proceso de elaboración del helado, basado en dos formulaciones iniciales. Mediante un diseño de mezclas, se generan diez formulaciones posibles, y se aplica un análisis de regresión lineal múltiple considerando la crema de leche, la leche en polvo entera y la leche condensada como factores de estudio, en relación a variables clave de respuesta como el overrun, el rendimiento, los sólidos solubles y los costos. La ecuación de Scheffé, obtenida a través del método de mínimos cuadrados, describe la relación entre estas variables. El análisis se completa con un ANDEVA para detectar diferencias significativas entre las formulaciones. La formulación F6 se identifica como la más óptima, con una deseabilidad global del 22.45%, cumpliendo con las restricciones propuestas y destacando como la elección preferida para la producción de helado de crema que equilibra la calidad del producto y la eficiencia económica en la industria alimentaria.
