A simplified design solution for shear capacity of post-installed anchors encompassing all failure modes in EC2-4 (2018)
Authors: Ng L T , Looi D T W , Lee J , Ng A L Y 
Published: June 2023

Abstract
Post-installed anchors are commonly used for steel-to-concrete connections, attributable to ease of installation as drilling technology advances. Besides, they offer the advantage of minimizing misalignment issues during construction compared to cast-in anchors. The anchor design calculations in EN 1992-4:2018 can be daunting for practicing engineers, given its complexity and state-of-the-art compared to ETAG 001 (2013). In an earlier publication, the authors described a methodology for simplifying the complex empirical equations in EN 1992-4:2018 for designing the tensile capacity of post-installed anchors into a simplified design tool. This work is a sequel to the previous work to develop a simplified design tool for estimating the design shear capacity of post-installed anchors (mechanical and bonded anchors) encompassing all failure modes. The calculation was first automated using a spreadsheet for the characteristic shear resistance of anchors and was verified using Hilti PROFIS Engineering software. The simplified design tool is summarized based on the lowest resistance of the anchor encompassing all failure modes. The design tool is demonstrated for an example of a 125 mm thick C30/37 concrete slab for commonly available anchor sizes of M8, M10, M12, M16, M20, and M24.

Abstract
The proper disposal of fibre waste products is a significant issue for the GFRP industries; as a result, the reuse and recycling of these waste products require sustainable solutions. Given that FRP materials, especially those created with thermosetting resins, cannot be reprocessed, so the majority of thermosetting FRP waste will be dumped in landfills. Innovative approaches are thus required to manage waste. This study investigates the performance of the FRP waste, known as Glass Fibre Reinforced Polymer (GFRP), that is ground to 0.15mm to 2.36mm in size and used to replace sand at 5%, 10%, 15%, 20%, and 25% by weight of the concrete composite. The experimental work starts with the grinding and sieving process, followed by preparing grade 45 concrete. Then the workability of concrete with GFRP was determined, followed by the compression, and split tensile strengths. The findings showed that adding up to 5% of GFRP waste as a partial replacement for fine aggregate improved the workability and compressive strength of the concrete mix. but decreases when more GFRP waste is added. While the split tensile strength shows increments in line with the increasing amount of GFRP waste replacement. It can be concluded that GFRP waste replacement has the potential to be used in the construction industry, however, the long-term performance must be determined first.

Abstract
Recently, the disposal of waste tire rubber is no longer a non-common environmental problem, which is due to its non-biodegradable nature. Many works were done with regard to the utilization of crumb rubber from waste tires into concrete. In conjunction to deal with the disposal issues, this effort also preserving the natural sources of aggregate and producing a green sustainable concrete. In this study, the crumb rubber was used in the concrete containing metakaolin and it replaced fine aggregate content at 10% and 15%. The investigations were conducted on the mechanical properties of concrete like compressive strength, split tensile strength, flexural strength and elastic modulus. The result showed reduction in mechanical properties is proportionate with the increment of crumb rubber. The bond between cement paste and rubber particles was found to be a factor affecting its strength. The finding indicated that the strength of blended-rubberized concrete decreased about 13% with increasing crumb rubber content from 10% to 15%. Thus, the study concluded that there was no significant strength reduction for rubberized concrete with increasing crumb rubber content (up to 15%). Furthermore, the compressive strength was complied to the minimum requirement for building structural application (25MPa). Thus, the blended-rubberized concrete has promising potential properties for the construction applications.

Abstract
This study presents techniques for the mass production of large-sized GEM foils for the
CMS phase-2 upgrade by the Korean CMS group. The foil production facility is designed with a
focus on mass production, including the adoption of the double-mask technique. A polyimide wet
etching technology that uses mono ethanolamine is reported, providing a safer working environment
due to its lower inhalation toxicity compared to ethylene diamine. The study also covers the
denaturation of the etchant over time and the process of retuning. Finally, R&D results on
soldering surface mount resistors with hot air for faster production are discussed.

Published: June 2023

Abstract
The intensity and energy spatial distributions of collimated laser Compton scattering (LCS) γ-ray beams and of the associated bremsstrahlung beams have been investigated as functions of the electron beam energy, electron beam phase space distribution, laser optics conditions and laser polarization. We show that the beam halo is affected to different extents by variations in the above listed parameters. In the present work, we have used laser Compton scattering simulations performed with the eliLaBr code (https://github.com/dan-mihai-filipescu/eliLaBr) and real LCS and bremsstrahlung γ-ray beams produced at the NewSUBARU synchrotron radiation facility. A 500 μm MiniPIX X-ray camera was used as beamspot monitor in a wide γ-ray beam energy range between 1.73 MeV and 38.1 MeV.
Biomimetic polymer fibers—function by design

Published: June 2023

Abstract
Biomimicry applies the fundamental principles of natural materials, processes, and structures to technological applications. This review presents the two strategies of biomimicry—bottom-up and top-down approaches, using biomimetic polymer fibers and suitable spinning techniques as examples. The bottom-up biomimicry approach helps to acquire fundamental knowledge on biological systems, which can then be leveraged for technological advancements. Within this context, we discuss the spinning of silk and collagen fibers due to their unique natural mechanical properties. To achieve successful biomimicry, it is imperative to carefully adjust the spinning solution and processing parameters. On the other hand, top-down biomimicry aims to solve technological problems by seeking solutions from natural role models. This approach will be illustrated using examples such as spider webs, animal hair, and tissue structures. To contextualize biomimicking approaches in practical applications, this review will give an overview of biomimetic filter technologies, textiles, and tissue engineering.

Abstract
Behavior gives valuable information for tiger’s management care. Tigers may perform stereotypic behavior as coping mechanism or stress in captivity. Enrichment techniques can reduce those stereotypic behavior. This research aims to evaluate food and environmental enrichment techniques on Sumatran tiger. Four tigers were observed by focal animal sampling (from 08.00 a.m. to 12.00 a.m. and 01.00 p.m. to 05.00 p.m.) at Tambling Wildlife Nature Conservation Rescue Centre. Tiger’s behaviors were categorized into active, inactive and stereotypic. Two tigers (1 female and 1 male) were observed for 2 days each baseline and post-enrichment. Two tigers (both males) were observed for 4 days each baseline and post-enrichment. Novel woods were introduced to the tigers’ enclosures for environmental enrichment. Fresh chicken meats (2 – 5 kg) were given disorderly at tigers’ enclosures as food enrichment. Baseline and post-enrichment behaviors were analzyed with Wilcoxon. The outcome was tigers’ stereotypic behavior (Z = -1,461, P = 0,144 > 0,05), active behavior (Z = -1,826, P = 0,680 > 0,05) and inactive behavior (Z = -1,095, P = 273 > 0,05) were not significantly reduced by these enrichment techniques. Other enrichment techniques need to be explored even more for tigers’ management care.

Abstract
One of the most significant global public health issues is malaria. Combination treatment of S. ligustrina blum wood with Dihydroartemisinin-piperaquin phosphate (DHP) as an antimalaria to increase the effectiveness of S. ligustrina blum wood extract. The purpose of this study was to see how effective the combination of aquadest extract (AE) and 25% ethanol extract (EE) of S. ligustrina blum wood with DHP was against P. berghei ANKA. S. ligustrina blum wood extract were extracted by maceration using aquadest and 25% ethanol. The extract formulated into capsules with or without DHP. Fifty DDY mice were divided into 10 groups (n = 5). Group I was infected infected-untreated, group II was received 25 mg/kg BW of dihydroartemisinin and 197 mg/kg BW of piperaquine phospate, and the others group of mice inoculated with 1x106
P. berghei ANKA and treated with 200 mg/kg. Blood samples were taken every day, starting from the first day to the tenth day. The number of parasites and erythrocytes was calculated using the image photoshop program, then the percentage of parasitemia and inhibition was determined. There was no difference between AE and EE in combination with half dose of DHP with DHP control, but significantly different with infection control. S. ligustrina blum wood extract worked synergistic with DHP as an antimalaria with a percentage of inhibition approaching 100% on the 10th day after treatment. S. ligustrina blum wood extract has the potential to be developed as an effective and safe combination antimalaria drug with pure chemical active ingredients.
2021 Quantitative Risk Assessment of Antimicrobial Residues in Pork Samples from Slaughterhouses in Laguna Using Monte Carlo Simulation.
Authors: Gacosta F D , Pangga G V 
Published: June 2023

Abstract
A quantitative risk assessment of antimicrobial residues in pork liver samples from slaughterhouses in Laguna, Philippines was performed to determine the probability of occurrence of adverse effects on the population upon consumption of antimicrobial residues in pork products. A cross-sectional study was conducted to collect data regarding the daily pork consumption of the population study. Meanwhile, secondary data on antimicrobial residues of quinolone, ceftiofur, florfenicol, streptomycin, tetracycline and tylosin found in pork liver samples were obtained from a previous study by Datuin (2018). Monte Carlo simulation using @RISK software was then used to calculate the estimated daily intake of the population and the risk associated with exposure to the antimicrobial residues. Results showed that the population of Laguna had a mean daily intake of 155 grams of raw pork and 92 grams of processed pork in the year 2021. Also, the calculated mean and maximum estimated daily intakes for each antimicrobial residue were within the acceptable daily intake and no hazard quotient exceeded the value of one during risk characterization. Therefore, the study concludes that antibiotic residues in pork products from slaughterhouses in Laguna pose low risk to the health of pork consumers. Nonetheless, precaution on the use of antimicrobials is still warranted, especially with the administration of tetracycline which had the highest hazard quotient out of the six antimicrobial residues.

Abstract
Pigs are the most appropriate species in cardiovascular research, one of which is myocardial infarction. This study aimed to obtain data on the number of leukocytes in domestic pigs (Sus scrofa domestica) before and after heart infarct surgery. A total of six four-month-old pigs at the Teaching Animal Hospital, IPB University, had their blood samples taken through the jugular vein, then put into a vacuum tube containing an anticoagulant (K3EDTA) for further testing using a hematology analyzer. Data were analyzed descriptively. The results of the study from 6 samples analyzed that the average number of leukocytes before and after heart infarct surgery were 16.33 ± 3.62 x 103/μL and 16.97 ± 4.59 x 103/μL. The increase in leukocytes in the blood cannot be used as an independent predictor to diagnose cardiac infarction. This is because many events can trigger an increase in the number of leukocytes in the blood, such as inflammation during heart infarct surgery.

Published: June 2023

Abstract
From 2019 until 2022, some villages in Gunungkidul had anthrax outbreaks twice and infected some people. These facts raise the question: Do the farmers know enough about anthrax and its risk? This study aims to identify the association between farmers’ knowledge of anthrax from the anthrax outbreak village in Gunungkidul regency and their decision to trade cattle. This study was achieved at four anthrax outbreak villages in Gunungkidul Regency; 155 farmers answered the questionnaire, collecting information about knowledge, attitude, and practice about anthrax. Demographic and Knowledge, Attitude, and Practice (KAP) data were analyzed descriptively. The association between knowledge about anthrax and their decision to trade cattle in the anthrax outbreak suspect village was measured by chi-square and odds ratio. The average score of farmers’ anthrax knowledge is 3,14, ranging from a score of 0 to 8 and a median of 3. 65 farmers have good knowledge of anthrax, and 90 farmers have bad knowledge of anthrax. Fourteen of 65 farmers with good knowledge and 21 of 90 with bad knowledge farmers decided still trade cattle from the anthrax-outbreak suspect village. This study found that knowledge of anthrax has no impact on the farmers’ decision to trade cattle from the anthrax-outbreak suspect village (odds ratio (OR) 0.9, 95% confidence interval (CI) 0.42-1.94, P = 0.792). The education method that has been used on farmers needs to be evaluated to make farmers have better knowledge, attitude, and practice toward anthrax; further study is required to find the appropriate method of anthrax education.
Post-Mining goes international: Hurdles to climate neutrality using the example of China
Authors: Tiganj J , Li Y , Kretschmann J 
Published: June 2023

Abstract
The topic of post-mining is becoming increasingly important globally in times of climate change and sustainability. This includes not only dealing with the post-mining heritage through adequate mine water management or environmental monitoring. Rather, it requires concepts for a successful transition in affected mining regions. China, as the world’s largest mining country, offers an important point of reference here. In coal-intensive regions, economic viability is closely linked to the coal industry. Structural change requires additive policies and restructuring to create, on the one hand, innovative conversion opportunities such as the integration of renewable energies into existing mines. On the other hand, plant closures are followed by unemployment for former workers. Here, on the other hand, the creation of alternative employment and new incentives is needed to minimize the consequences for citizens and the environment. Nevertheless, it can be stated that it is essential to reuse abandoned mines in order to support several factors: Efficient use of existing resources, cost reduction, creation of alternative jobs, protection of industrial heritage, modernization of history, sustainability and green development. The driver behind this research is to actively contribute to a livable sustainable future, nationally and internationally. This area has many research gaps that need to be filled to promote internationalization and individual development. Therefore, the results are transferred from German experiences to an international level by taking China as a dominant coal player into account.
Numerical analysis of discontinuous berm-supported shallow excavations for building construction
Authors: Muñoz Miguel Ángel Millán , Carrizosa David Mencías , García Alejandro Calle 
Published: June 2023

Abstract
The use of discontinuous berms remains a common strategy in medium-rise urban excavations when a uniform slope is not safe enough and certain conditions are met. However, despite its frequent use, there is no broad and contrasted reference that allows its design and verification in a similar way to how it is done in the usual homogeneous slopes, either by abacus such as those of Taylor or Hoek and Bray or the two-dimensional numerical calculation with bishop’s method, finite elements, or finite differences, among others. The difficulty associated with the calculation of slope stability with discontinuous berms lies in the fact that it is basically a three-dimensional problem, not admitting any of the simplifications that allow it to be reduced to a two-dimensional case and use one of the methods mentioned above. The present research is oriented to model an excavation with discontinuous berms, considering its three-dimensional configuration and including as main variables the height of the excavation, the width between berms, and the properties of the terrain, represented with a Mohr-Coulomb failure criterion. From a large number of calculations, the necessary regressions will be obtained to allow a pre-design and verification of the main cases that arise in practice. The article presents the results obtained and details the advantages and disadvantages of the associated methodology.

Published: June 2023

Abstract
Between climate change and anthropogenic forcing, pressure on water resources is continually increasing all over the world. The growing population is gathering more and more in cities where the artificialization of soils and urban developments of all kinds are modifying the local water cycle. However, knowledge about the hydrological cycle in urban areas is not well developed today. Urbanization in a watershed can produce significant changes to the natural water cycle, mainly because permeable soils have been covered by less permeable surfaces. The consequences of this urbanization can be significant and multiple. The assessment of urban water resources aims to provide a suitable circumstances for planning, conditions for the planning, design, construction, operation, and maintenance of works used for irrigation and sanitation, among other applications. The methodology of the research is based on the data collection, which includes climatic data from June 2021 to June 2022 and the use of Digital elevation model to create a hydrographic network. The second part is land use data processing to create a land cover map using maximum Likelihood Supervised Classification, by combining different band composites of Landsat 8 images and NDVI to differentiate between vegetative and non-vegetative areas. However, CORINE Land Cover database was utilized to distinguish between continuous and discontinuous urban area in this classification. The final step in the process is to determine the hydrological coefficients by calculating the water cycle parameters (Evapotranspiration Runoff and Infiltration) for each land-use class. Furthermore, establishing a link between land use and hydrological behaviour and conducting a precise calculation of water balance-related coefficients in urban areas using Urban Atlas 2018.

Abstract
This paper is a continuation of the research on the application of artificial intelligence in counting trees with the use of methods for the automatic analysis of photogrammetric data in forests of the continental region. This paper is devoted to the AI application in accelerating decision making processes in forest management. It also discusses how RGB imagery from drones could replace aerial and satellite hyperspectral imagery and automatically detect unhealthy and dead trees. Experimental research was conducted to verify whether Faster R-CNN can automatically detect and classify snag and trees weakened by diseases on aerial RGB data, enabling a quick response to forest-threatening factors. The research is based on photogrammetric data taken in areas of forest districts subordinate to the Regional Directorate of State Forests in Zielona Góra. Non-metric imagery data was collected from drones and small airplanes with a photogrammetric container and postprocessed with respect to the photogrammetric constraints. The results show that in specific cases aerial and satellite hyperspectral imagery can be replaced by RGB orthomosaics in order to decrease the time needed for forestry treatments.

Published: June 2023

Abstract
Spectral indices derived from remote sensing data such as NDVI, SAVI, NDBI, NDWI, and MNDWI were modified using various mathematical operations to enhance the overall accuracy of the automated mapping built-up (BU) areas. Although some of the modified spectral indices succeed in improving the accuracy of mapping BU areas, their performance as land surface temperature (LST) indicators needs to be investigated. Hence, this paper aims 1) to assess the performance of various spectral indices as LST indicators and 2) to investigate the relationship between performance of spectral indices as LST indicators and their accuracy for mapping BU areas. Research locations were located in Yogyakarta and Surakarta City, Indonesia. Spectral indices and LST were derived from Landsat 8. Results showed that NDBI, NDBI*MNDWI, NDVI*NDBI, and NDBI*SAVI were good LST indicators both in Yogyakarta and Surakarta proven by moderate to strong coefficient of Pearson correlation. The relationship between the performance of various spectral indices as LST indicators and their accuracy for mapping BU areas showed strong positive Spearman correlation by 0.69 and 0.73 for Yogyakarta and Surakarta, respectively. In other words, spectral indices, for both original and modified indices, with good accuracy for automated mapping BU areas tended to be good LST indicators.
