Critical thinking skills are needed by scientists. This study aims to develop and implement innovative project-based learning resources with multimedia to build critical thinking skills in Cation Analysis teaching. The study was conducted at the State University of Medan, involving 60 students that grouped as experimental and control classes. The research are developing innovative project-based learning resources, standardizing, and implementing it in the teaching of Analytical Chemistry. The results of the study indicate that the standard project-based learning resource package with multimedia equipped with learning tools has been designed systematically, completely, and packaged in electronic form for blended learning. Students can complete assigned projects, starting from planning, implementing, and reporting, and practicum used in the control class. Subjective assessment of project and practicum activities showed that students’ critical thinking skills in the experimental group (M=85.16±2.42) were higher than the control group (M=76.17±4.38). An increase in learning outcomes occurred in the experimental group, as indicated by the achievement of students in the experimental class (M=78.16±6.62) which was higher than the control class (M=71.66±6.73), and the two groups were significantly different (t-test 3,88>t-table 2,04). Student competence in analytical chemistry is achieved because innovative learning resources motivate students to study optimally.

In light of the recent data for B¯(s)→D(s)(*)P and B¯(s)→D(s)V decays, we perform a model-independent phenomenological analysis in the presence of quasielastic rescattering. With the Wilson coefficients including contributions beyond the standard model, the lifetimes of the B meson and Bd0−B¯d0 mixing are investigated to clarify correlations among the observables. We show that parameter regions for quasielastic rescattering, the size of color-suppressed tree amplitudes, and new physics are constrained due to the lifetime data. As a consequence, it is revealed that this scenario can be tested by the future LHCb measurement of the width difference in Bd0−B¯d0 mixing and semileptonic CP asymmetry.

The negative effects of climate change have burdened humanity with the necessity of decarbonization by moving to clean and renewable sources of energy generation. While energy demand varies across the sectors, fisheries, including fishing and aquaculture, are among the most energy intensive processes in the food production industry. The synergistic opportunities for co-located aquaculture and renewable energy can thus provide a multifunctional use of space and resources, creating opportunities to meet the identified energy demands of a variety of aquaculture operations. This study has investigated a sustainable energy model for a small-scale shrimp farm in western Taiwan with synergies for the dual use of the water area for solar photovoltaic electricity generation and aquaculture. Based on the simulation results and SWOT analysis, recommendations have been made for the design and operation of a solar-powered aeration system for shrimp farms. The average monthly energy production of 32 MWh is attainable at the estimated canopy space on a carport by installing 896 solar modules on the proposed site, fully covering the power demand of the shrimp farm. These findings have significance for encouraging effective practices in deploying solar techniques in aquaculture and making them replicable in global settings. © 2023 by the authors.

Background: Taiwan, deeply impacted by the 2003 SARS outbreak, promptly implemented rigorous infection control and prevention (ICP) measures in January 2020 to combat the global COVID-19 pandemic. This cross-sectional serologic study was conducted among healthcare workers (HCWs) in a tertiary care hospital in Taiwan from August 1, 2022, to February 28, 2023. The study aimed to assess HCWs’ antibody responses to COVID-19 vaccination against Omicron subvariants BA.1, BA.4, and BA.5, considering variations in prior infection. Additionally, it evaluated the effectiveness of ICP and vaccination policies within the hospital setting in Taiwan. Methods: A cross-sectional serology study was conducted in Taiwan to investigate the seroprevalence rates of Omicron subvariants BA.1, BA.4, and BA.5 among HCWs. A total of 777 HCWs participated in this study. A structured questionnaire was collected to obtain the epidemiological characteristics and risk factors for potential exposure. Enzyme-linked immunosorbent assay was used to detect antibody responses. Serum samples were selected for protection against Omicron subvariants BA.1, BA.4, and BA.5 by using a pseudotyped-based neutralization assay. Results: More than 99% of the participants had received SARS-CoV-2 vaccination. Overall, 57.7% had been infected with SARS-CoV-2, with some being asymptomatic. The SARS-CoV-2 Anti-Spike S1 protein IgG (Anti-S) distribution was 40,000 AU/mL for 20.2% (157/777) of participants, with a mean ± standard deviation of 23,442 ± 22,086. The decay curve for Anti-S was less than 20,000 AU/ml after 120 days. The probability curve of 50% neutralization showed an Anti-S of 55,000 AU/ml. The optimum Anti-S was 41,328 AU/mL (equal to 5,869 WHO’s standard BAU/mL), with 86.1% sensitivity and 63.5% specificity. Conclusions: In this significant study, 20.2% of HCWs achieved seroprotection against Omicron subvariants BA.1, BA.4, and BA.5. Their immunity against Omicron subvariants was further reinforced through

Aims. In this work, we intend to examine how environment influences the merger fraction, from the low density field environment to higher density groups and clusters. We also aim to study how the properties of a group or cluster, as well as the position of a galaxy in the group or cluster, influences the merger fraction. *** identified galaxy groups and clusters in the North Ecliptic Pole using a friends-of-friends algorithm and the local density. Once identified, we determined the central galaxies, group radii, velocity dispersions, and group masses of these groups and clusters. Merging systems were identified with a neural network as well as *** these, we examined how the merger fraction changes as the local density changes for all galaxies as well as how the merger fraction changes as the properties of the groups or clusters change. Results. We find that the merger fraction increases as local density increases and decreases as the velocity dispersion increases, as is often found in literature. A decrease in merger fraction as the group mass increases is also found. We also find groups with larger radii have higher merger fractions. The number of galaxies in a group does not influence the merger fraction. Conclusions. The decrease in merger fraction as group mass increases is a result of the link between group mass and velocity dispersion. Hence, this decrease of merger fraction with increasing mass is a result of the decrease of merger fraction with velocity dispersion. The increasing relation between group radii and merger fraction may be a result of larger groups having smaller velocity dispersion at a larger distance from the centre or larger groups hosting smaller, infalling groups with more mergers. However, we do not find evidence of smaller groups having higher merger fractions. Copyright © 2024, The Authors. All rights reserved.

The continuous use of oil and gas fuels causes a global energy crisis and environmental pollution, so it is necessary to use renewable and environmentally friendly energy sources. Microbial fuel cell (MFC) is a technology that can generate electricity by converting chemical energy into electrical energy using microorganisms as a catalyst. This research aimed to determine the potential of red algae (Eucheuma cottonii) as a substrate in MFC to generate electrical energy. This research used a dual-chamber MFC model. Anode chamber contains hydrolyzed red algae cellulose, peptone, yeast extract, KH2PO4, and methylene blue (this mixture is autoclaved before being put into the anode chamber), while the cathode chamber contains 0.2 M KMnO4 as the electrolyte solution. This reactor used Nafion 117 membrane as a proton exchange membrane. The electrical measurement was carried out every 4 hours for 48 hours. The highest power density using red algae as a substrate was 982 mW/cm2 with a value of maximum current 0.52 mA and potential different 370 mV. It is concluded that red algae (E. cottonii) extract can be employed as a subtract in the MFC system to produce electrical energy.
