Authors: Gerges Nagib N. , Issa Camille A. , Khalil Nariman J. , Abdul Khalek Lara , Abdo Serge , Abdulwahab Yehia
Published: November 2023

In the construction industry, concrete is the most utilized building material. It is produced from different natural resources such as sand and gravel, as well as cement. The production of concrete is causing harm to the environment, yet its use became a necessity. To solve this humongous environmental challenge, many researchers devoted a considerable effort to partially replacing concrete mix components with waste material derived from glass, plastics, aluminum, wood ash, construction and demolition wastes, or tires. In the current study, a novel effort was conducted to incorporate all the above-mentioned wastes in a concrete mix design and to assess its performance. Five recycled mix designs were explored and based on the concrete mechanical properties derived, an optimum mix was realized. The optimum mix incorporated the following waste percentages: 2% crumb rubber (CR) partially replacing sand, 20% powdered glass (PG) partially replacing sand, 50% recycled concrete aggregates (RCA) partially replacing coarse aggregates, and the addition of 0.5% plastic. The optimum recycled mix was utilized to cast a real-life-size reinforced concrete beam which was compared to a normal mix beam.
Uplifting of anticorrosive coatings performance via TiO2/ZnO core–shell pigment for oil and gas pipelines protection
Authors: Ahmed N. M. , Mohamed M. G.
Published: November 2023

The objective of this study is to enhance the effectiveness of anticorrosive coatings applied to steel pipelines utilized for the transportation of petroleum products. However, these pipelines are susceptible to corrosion, necessitating the implementation of an economically viable protection system. Therefore, this research endeavors to introduce a novel pigment consisting of titanium dioxide/zinc oxide (TiO2/ZnO) core–shell structure. The pigment is designed to be incorporated into polymeric coating formulations and subsequently subjected to standard testing methods, including immersion tests, adhesion assessments, and electrochemical measurements. The pigment was synthesized and characterized using X-ray diffraction (XRD), X-ray fluorescence (XRF), and electron microscopy (SEM and TEM). Electrochemical impedance spectroscopy (EIS) was hired for observing the resistance and capacitance of the formulated coatings through immersion in corrosive medium (3.5% NaCl). The obtained results conveyed that the prepared core–shell pigment with its unique structure had strongly elevated the resistivity of the formulated coating, which enhanced its role in the protection of the pipeline wall from corrosion.

Published: November 2023

Multiple surface treatment methods for titanium alloy prostheses, widely used in orthopedics, are available; however, these can affect bone integration and regeneration efficiency. In this study, through cell and animal experiments, we devised seven bone implant categories of Ti6Al4V based on surface preparation and post-processing technology (polishing, grit-blasting, fine titanium spraying, coarse titanium spraying, electron beam melting [EBM] printing, selective laser melting [SLM] printing, and post-processed SLM printing) and imaged each microscopic surface structure with a scanning electron microscope (SEM). Mechanical testing revealed excessive post-processing damaged the mechanical properties of the implants. In vitro, human bone marrow mesenchymal stem cells (hBMSCs) were cultured with implants, and the morphology of the cells adhering to the implant surface was observed using SEM and confocal laser scanning microscopy. Cell Counting Kit-8 (CCK-8) semi-quantitatively determined cell activity, indirectly reflecting the proliferation of hBMSCs. Alizarin red and alkaline phosphatase experiments assessed osteogenic differentiation. In vivo, experiments utilized the New Zealand rabbit femoral condyle bone defect model to assess bone regeneration and integration using micro-computed tomography, Van Giesen staining, and Masson staining. We found that 3D-printed implants with regular pore structures were more conducive to hBMSC osteogenic differentiation, while the presence of metal powder on NPT-SLM-printed implants hindered such differentiation. The post-treatment SLM scaffold surface may have some residual semi-melted powder; however, these powder residues have no significant effect on cell activity and differentiation. Surface treatment (grit-blasting and titanium spraying) of planar structures can enhance hBMSC adhesion but does not necessarily promote their differentiation. The framework structure of 3D printing may affect the osteogenic differentiation of hBMSCs, and for SLM-printed implants, excessive pursuit of a “powderless” state will damage the mechanical properties of the implant.

We aimed to evaluate sex differences in the effects of moderate-intensity statin with ezetimibe combination therapy (rosuvastatin 10 mg plus ezetimibe) versus high-intensity statin (rosuvastatin 20 mg) monotherapy in patients with atherosclerotic cardiovascular disease (ASCVD). This was a sex-specific subgroup analysis of the RACING trial that evaluated the interaction between sex and treatment strategies for the primary outcome (composite of cardiovascular death, major cardiovascular events, or nonfatal stroke at 3 years). Of 3780 patients in the RACING trial, 954 (25.2%) were women. Regardless of sex, the effect of moderate-intensity statin with ezetimibe combination therapy on primary outcome compared with high-intensity statin monotherapy was similar (hazard ratio [HR] 0.98 [0.63–1.52] in women; HR 0.90 [0.71–1.14] in men). The rate of discontinuation or dose reduction of study drugs due to intolerance was lower in the ezetimibe combination group than in the high-intensity statin monotherapy group in both women (4.5% vs. 8.6%, P = 0.014) and men (4.8% vs. 8.0%, P < 0.001). LDL cholesterol levels of < 70 mg/dL at 1, 2, and 3 years were more frequently achieved in the ezetimibe combination group than in the high-intensity statin monotherapy group (all P < 0.001) in both sexes. There were no significant interactions between sex and treatment groups regarding the primary outcome, discontinuation, or dose reduction of study drugs, or the proportion of achievement of LDL cholesterol levels < 70 mg/dL. The effect of ezetimibe combination therapy for the 3-year composite outcomes was not different in both men and women. The benefits of ezetimibe combination therapy on LDL cholesterol lowering and drug tolerance were similarly observed regardless of sex.

Authors: Li Bai-jia , Zhu Ting-ting , Hu Xiao-ying , He Chao-man
Published: November 2023

This study aimed to analyze the independent risk factors for predicting preeclampsia severity and explore its underlying mechanism. Clinical data of patients with preeclampsia were collected from the Medical Information Mart for Intensive Care (MIMIC)-IV database. Univariate and multivariate analyses were employed to assess the significant factors associated with preeclampsia severity. Additionally, we performed multivariate logistic regression analysis and mediation analysis to investigate the potential regulatory path. Based on inclusion and exclusion criteria, 731 participants were enrolled: severe preeclampsia (n = 381) and mild to moderate preeclampsia (n = 350). Age, white blood cells (WBC), platelet, creatinine, albumin, uric acid, aspartate aminotransferase, alanine aminotransferase, international normalized ratio, and prothrombin time were significantly related to preeclampsia severity. Besides, hospital length of stay was significantly higher in the severe group. Notably, age and uric acid were independent predictors for preeclampsia severity. Further, WBC and creatinine were significantly associated with uric acid. Finally, the mediation analysis showed that uric acid was a mediator of the relationship between WBC and preeclampsia severity. In conclusion, WBC might affect preeclampsia severity and progression via the mediation of uric acid. This study might provide novel insight into preventing preeclampsia development.

PFAS-free Moisture Barriers in Structural Firefighting Gear
Authors: Campbell G. E. , Glazer S. , Stinger B. , Thompson M. , Thompson S.
Published: November 2023

This chapter provides an evaluation of alternatives to the use of polytetrafluoroethylene (PTFE) as a moisture barrier in firefighter turnout gear. PTFE is effective as a moisture barrier because it is water and oil resistant, thermally stable, and breathable. While PTFE itself is considered inert and safe for commercial use, the use of carcinogenic PFASs in the manufacturing of PTFE that may be incorporated into the moisture barrier material is of concern. A two-pronged approach of policy evaluation and alternatives assessment was used to address the issue of PFASs in the moisture barrier of firefighter turnout gear. After conducting hazard and technical performance assessments on a variety of PFAS-free materials, this chapter proposes applying a hydrophobic coating or laminate onto a fabric to achieve a PFAS-free moisture barrier that minimizes hazards while meeting the required functions. Combining a fabric with a coating and a laminate all together could further enhance moisture barrier properties, but more research is needed to make a definitive statement on this alternative’s effectiveness. In addition to assessing chemical alternatives, this chapter proposes changes to the National Fire Protection Association’s testing standards for turnout gear, allowing PFAS-free materials to be considered in the evaluation process.

Context. Anomalous Cepheids (ACEPs) are intermediate-mass metal-poor pulsators that are mostly discovered in dwarf galaxies of the Local Group. However, recent Galactic surveys, including the Gaia Data Release 3, found a few hundred ACEPs in the Milky Way. Their origin is only poorly understood.

Aims. We aim to investigate the origin and evolution of Galactic ACEPs by studying the chemical composition of their atmospheres for the first time.

Methods. We used UVES at the Very Large Telescope to obtain high-resolution spectra for a sample of nine ACEPs belonging to the Galactic halo. We derived the abundances of 12 elements, C, Na, Mg, Si, Ca, Sc, Ti, Cr, Fe, Ni, Y, and Ba. We complemented these data with literature abundances from high-resolution spectroscopy for an additional three ACEPs that were previously incorrectly classified as type II Cepheids. This increased the sample to a total of 12 stars.

Results. All the investigated ACEPs have an iron abundance [Fe/H] < −1.5 dex, as expected from theoretical predictions for these pulsators. The abundance ratios of the different elements to iron show that the chemical composition of ACEPs is generally consistent with that of the Galactic halo field stars, with the exception of sodium, which is found to be overabundant in 9 out of the 11 ACEPs where it was measured. This is very similar to the situation for second-generation stars in Galactic globular clusters. The same comparison with dwarf and ultra-faint satellites of the Milky Way reveals more differences than similarities. It is therefore unlikely that the bulk of Galactic ACEPs originated in a galaxy like this that subsequently dissolved into the Galactic halo. The principal finding of this work is the unexpected overabundance of sodium in ACEPs. We explored several hypotheses to explain this feature, finding that the most promising scenario is the evolution of low-mass stars in a binary system with either mass transfer or merging. Detailed modelling is needed to confirm this hypothesis.

Data mining has the potential to empower healthcare organizations by allowing them to analyze various aspects of patient information and discover connections between seemingly unrelated data. By harnessing advanced data analysis techniques, healthcare providers can identify trends in patients' medical conditions and behaviours. The Apriori algorithm is used for mining frequent item sets and devising association rules from a transactional database. The parameters “support” and “confidence” are used. Support refers to items’ frequency of occurrence; confidence is a conditional probability, while Apriori-Hybrid. Apriori-Hybrid is the combination of algorithms Apriori and Apriori-TID, which can classify large itemsets and can improve the accuracy of classification and it can also shed light on the basic mechanism. In this research, a comparison was made between the two algorithms in terms of capabilities, strengths, areas of use, and suggestions about the nature of using each algorithm.

Published: November 2023

Furniture, a high-value-added product, is considered one of the strategic commodities for the economy in Indonesia because it is globally competitive. The furniture industry in Indonesia has grown by relying on local raw materials and human resources to keep its existence in the market. Despite Indonesia being known as a significant producer of raw materials for furniture due to its forestry area, the furniture export value is far behind compared to export value abroad. The offered price and appearance from abroad are more attractive than Indonesia's products. Therefore, there is a need to evaluate what factors influence the success of an industry. In general, the industry's success is mainly influenced by the interaction quality among all actors in the industry, either internal or external parties. Thus, the furniture industry needs to manage not only within the industry but also its supply chain effectively and efficiently. This study would like to evaluate the criteria and sub-criteria influencing the furniture industry's export competitiveness based on its supply chain, including circular economy implementation, and propose strategic recommendations. This study applies three methods: cut-off point, Analytical Network Process (ANP), and semi-standardized interview. The finding of this study indicates that the sub-criteria with the most decisive influence on Indonesia's furniture export competitiveness are operation cost, collaboration, and quality, respectively. Furthermore, a collaborative strategy between stakeholders in the furniture industry is proposed to increase the efficiency of operational processes, save operating costs, and increase product quality.

Published: November 2023

Water is the source of life for all living things on Earth. Indonesian people make groundwater the main source of water, including the people in Semarang City. The city of Semarang, which is the capital city of Central Java province, with the development of industry, trade and tourism growing rapidly, has forced groundwater exploitation on a large scale. As a result, disasters such as drought, the phenomenon of seawater intrusion and groundwater contamination have started to occur in the city of Semarang, especially in the alluvial plains area. This study aims to determine the level of groundwater contamination in the study area. In this study, 30 groundwater samples were taken to test the chemical content of groundwater. The methods used were the geospatial analysis and the Pollution Groundwater Index (PGI). The geospatial in Geographic Information System/GIS method aims to determine the distribution of groundwater quality in the study area. The PIG method aims to determine the level of groundwater contamination. PGI results show that there is 1 sample belonging to high pollution and 1 other sample belonging to groundwater with very high pollution. Geospatially, it shows that the distribution of groundwater contamination is in the western and central parts of the study area. This is also supported by geospatial analysis for the physicochemical conditions of groundwater which includes parameters of pH, EC, TDS and Hardness. From this research, it is known that groundwater in Semarang City is starting to experience pollution. So there is a need for efforts to restore groundwater conditions and start reducing the use of groundwater by utilizing surface water.Introduction

Published: November 2023

This study aims to understand Jakarta’s water supply structure and is a part of research on Jakarta’s water supply provision planning. Our analysis on a 14-year water balance estimation, statistic and archival analysis, as well as policy and institutional analysis identify that the metropolitan dependence on groundwater is immense; about 65% of water needs are supplied by groundwater and this has caused critical land subsidence in many areas including in the business center. Several projects to shift from groundwater to surface water have been carried out, and this study concluded that when these projects were to be completed in 2030, the number of people served by centralized piped water will be increased and the dependence on groundwater could be reduced. But at the same time, the reliance on supply from areas far from the city for centralized piped water system will also increase. To increase Jakarta water security, water supply provision planning should focus on processing local water.

Authors: Junaidi Junaidi , Oktiawan Wiharyanto , Ezha Pradana Handika
Published: November 2023

Electro-dewatering (EDW) is a hybrid technology for separating liquids from solids in the wastewater sludge dewatering process. EDW has excellent prospects because it is able to remove water from sludge with high efficiency and low energy consumption. EDW can be applied simultaneously with the dewatering process (filtration/compression) as a preliminary treatment or after the dewatering process. This study focuses on the effect of voltage and pressure on EDW performance. Several scenarios with voltage and pressure variations were applied to the sludge. The application of voltage of 20 V and 30 V and pressure of 5 kPa and 10 kPa were found to be good enough to remove the water content that could not be achieved by mechanical dewatering. A moisture content value of 66.56 % was obtained with a voltage of 30 V and 10 kPa pressure for 60 minutes. The experimental results show that the greater the applied voltage and pressure values, the higher the water content reduction rate. However, the application of EDW must pay attention to energy consumption which is closely related to the voltage (electric current generated) and the application time. This research can be used as a supporting theory and input in understanding the potential application of the EDW process for the treatment of soy sauce and syrup industry wastewater sludge.

One of the environmental problems found in developing countries, including Indonesia, is the waste problem. Waste management is the authority of the district or city government. Banyumas Regency is one of the areas that has experienced waste problems because the Final Processing Site (FPS) for its waste was closed and residents refused. In 2018, the Banyumas district received the title of waste emergency. At that time, in almost every corner of the city, there were piles of dirty and stinking garbage. Since the incident, it seems to be a whip for the local government to fix the waste problem. At present it can be said that they have been relatively successful in managing their waste, even to the point where the motto is that waste management is environmentally sound and educational. Based on that, it is interesting to study how the efforts were made and the criteria so that they dare to declare it as environmental and environmental-based waste management. The method used in this research is qualitative with interactive analysis. The results of the research show that waste management has been based on the environment with evidence in the form of; sorting waste from the source, processing which results in reducing the volume of waste at the sub-district and village level, product diversification from waste, processing into Refuse Derived Fuel (RDF) to achieve what is called zero waste. It has educational value because in the process of changing waste management through public education widely, especially in urban areas and more specifically to workers who are involved in various waste processing sites. In addition, the success of Banyumas Regency in managing waste is often used as a comparative study destination or a vehicle for education from various other local governments.

Lutan Lake in Palangkaraya is one of the most important oxbow lakes for the people of Palangka Raya. The many water resources with high economic value in Lutan Lake require sustainable management to maintain their quality. One of the indicators for determining lake water quality is the analysis of bio-indicators and water’s physical and chemical quality. The purpose of this study was to analyze the quality of lake water using the presence of biological indicators such as plankton and water quality parameters. This study used a quantitative descriptive method with a survey approach. The sampling was carried out at four stations with two-time variations, i.e., at 04.00 p.m. and 10.00 p.m. Based on the study’s results, it was found that the quality of Lutan lake water for classes I, III, and IV were included in the lightly polluted category. For class II, it was in the moderately polluted category. The plankton parameter shows that the index of phytoplankton and zooplankton diversity looks low with an indication of an unstable aquatic ecosystem due to the dominance of species which indicated the condition of the waters of Lake Luta has been polluted.
