Simulation Method for Measuring Multitasking Proficiency
Authors: Wulanyani Swasti 
Published: August 2023

AbstractMultitasking is defined as conducting several tasks simultaneously. There are three characteristics of multitasking. First, multitasking has circular characteristic and demand the performance of several tasks. Second, there is a shift of attention from one task to another. Third, the performance happens in limited time. Many companies apply multitasking to make their human resources more effective and efficient. If this proficiency can be predicted, companies will be able to reduce their expenses by appropriate selection or potential review to their human resources particularly in Indonesia. Therefore, this study attempted to create computerized simulation program as the measurement methods of multitasking performance. Simulation have reflected the real situation by: the existence of various types of matter in the three sets of tasks that must be done within a certain time limit, the subject can move or choose task that they want, and the presence of dual task. Measurement conducted in a quiet room, adequate temperature and lighting, and adjustable workstation. The result of this study built practical implication that the multitasking performance measurement method by using computerized simulation could create the multitasking condition. Therefore, companies or industrial practitioners can use the simulation method to measure the multitasking proficiency of their employees.

Authors: Sunethra A.A. , Sooriyarachchi M. R. 
Published: August 2023

AbstractThe literature clearly demonstrated how the random effect miss-specification in Generalized Linear Mixed Models (GLMMs) affect the model performance with respect to the Type II Errors of the Type III F-test. The method of Sandwich Variance Estimation (SVE) is a very popular method for improving the functionality of miss-specified models. This study attempted on examining whether the use of SVE could improve the Type II Errors of miss-specified GLMMs. A comprehensive simulation study comprising data from a Binary Logistic Mixed Model was performed of which the results clearly demonstrated that Type II Errors are being affected by random effect miss- specification. The novel finding of the study was that the adoption of SVE failed to contribute significantly to improve the functionality of GLMMs when random effects of the GLMMs are not correctly specified.

Authors: Togashi Dai , Nodera Takashi 
Published: August 2023

AbstractThe W-GCV method is one of the iterative methods used to solve a large scale Vtandard form of the Tikhonov regularization, but it is also necessary for solving the general form of the Tikhonov regularization. This paper proposes a new solver, called GKB-GCV, which is an extension of the W-GCV by using the GSVD. Numerical results are presented to show the usefulness of the GKB-GCV method in large scale ill-posed problems.

Published: August 2023

Maize is one of the major crops in the world and the most productive member of the Gramineae family. Since cold stress affects the germination, growth, and productivity of corn seeds, the present study aimed to investigate the effect of seed biopriming with Trichoderma harzianum on the tolerance of two genotypes of maize seedlings to cold stress. This study was conducted in triplicates in factorial experiment with a complete randomized block design (CRBD). The study was conducted in the greenhouse and laboratory of the University of Mohaghegh Ardabili, Ardabil, Iran. Experimental factors include two cultivars (AR68 cold-resistant and KSC703 cold-sensitive maize cultivars), four pretreatment levels (control, biopriming with T. harzianum, exogenous T. harzianum, and hydropriming), and two levels of cold stress (control and cold at 5 °C) in a hydroponic culture medium. The present study showed that maize leaves’ establishment rate and maximum fluorescence (Fm) are affected by triple effects (C*, P*, S). The highest establishment (99.66%) and Fm (994 units) rates were observed in the KP3 control treatment. Moreover, among the pretreatments, the highest (0.476 days) and the lowest (0.182 days) establishment rates were related to P0 and P3 treatments, respectively. Cultivar A showed higher chlorophyll a and b, carotenoid content, and establishment rate compared to cultivar K in both optimal and cold conditions. The highest root dry weight (11.84 units) was obtained in cultivar A with P3 pretreatment. The pretreatments with T. harzianum increased physiological parameters and seedling emergence of maize under cold and optimal stress conditions. Pretreatment and cultivar improved catalase activity in roots and leaves. Higher leaf and root catalase activity was observed in the roots and leaves of cultivar K compared to cultivar A. The cold treatment significantly differed in peroxidase activity from the control treatment. Cultivar K showed higher catalase activity than cultivar A. The main effects of pretreatment and cold on polyphenol oxidase activity and proline content showed the highest polyphenol oxidase activity and proline content in hydropriming (H) treatment. Cold treatment also showed higher polyphenol oxidase activity and proline content than cold-free conditions.

Published: August 2023

Precision land leveling must be treated as a precursor technology for improving crop yield, enhancing input-use efficiency and ensuring long-term sustainability of the resources. A field experiment was conducted in Dongola Agricultural Research Farm, Northern State, for two successive seasons to investigate the effect of three type of ploughing; heavy disc harrow (H1), disc plough (H2) and no-ploughing (H3), and three land leveling techniques, Laser (L), Scraper (S) and traditional (T),on wheat production. The experiment was arranged in a strip split plot design and the treatments were replicated three times.
The results indicated that effective field capacity, fuel consumption, and slippage were significantly affected by ploughing method. Laser land leveling recorded the highest fuel consumption (16.3 L/hr), and the lowest field efficiency (55%). while the heavy disc harrow recorded the highest effective field capacity (0.98 ha/hr), field efficiency (71.2%) and wheel slippage (8.1%). The soil moisture content (db %) was increased with time and depth. The highest mean soil moisture content was obtained with the laser land leveling and heavy disc harrow treatment at 75-100cm soil depth as 24.82%. The results revealed that the highest average grain yield (4.63 ton/ha) and infiltration rate (31cm/hr) were also recorded by the laser land leveling and heavy disc harrow. The treatments showed significant differences at the 5% level between the treatments for the parameters measured. Multiple regression analysis showed a highly significant effect (P≤ 0.001) of laser leveling with disc harrow ploughing on grain yield, compared to the other treatments used in the study (R2 = 0.40). The relation between the grain yield (Y) and the treatments: X1 ploughing, X2 leveling is summarized in the following equation:
Y = 2.875 + 0.552X1 + 0.254X2
The study concluded that, although Laser leveling has increased the grain yield with high cost, yet it is not an expensive technique when the cost is distributed over the period of Laser leveling. The highest grain yield was obtained by the heavy disc harrow with laser land leveling.

Authors: Ren Ping , Dong Jingyan 
Published: August 2023

AbstractThe generation of electronic waste (e‐waste) poses a significant environmental challenge, necessitating strategies to extend electronics’ lifespan and incorporate eco‐friendly materials to enable their rapid degradation after disposal. Foldable electronics utilizing eco‐friendly materials offer enhanced durability during operation and degradability at the end of their life cycle. However, ensuring robust physical adhesion between electrodes/circuits and substrates during the folding process remains a challenge, leading to interface delamination and electronic failure. In this study, electrohydrodynamic (EHD) printing is employed as a cost‐effective method to fabricate the eco‐friendly foldable electronics by printing PEDOT:PSS/graphene composite circuits onto polyvinyl alcohol (PVA) films. The morphology and electrical properties of the printed patterns using inks with varying graphene and PEDOT:PSS weight ratios under different printing conditions are investigated. The foldability of the printed electronics is demonstrated, showing minimal resistance variation and stable electronic response even after four folds (16 layers) and hundreds of folding and unfolding cycles. Additionally, the application of printed PEDOT:PSS/graphene circuit is presented as a resistive temperature sensor for monitoring body temperature and respiration behavior. Furthermore, the transient features and degradation of the PEDOT:PSS/graphene/PVA based foldable electronics are explored, highlighting the potential promise as transient electronics in reducing electronic waste.

AbstractThis study explored diethanolammonium chloride ([DEA]Cl) as a potential ionic liquid from low‐cost and commercial ones for gas separation. There are three kinds of functional sites in [DEA]Cl: acidic NH2+, hydrogen‐bond OH, and nucleophilic Cl−. The separation of NH3/N2/H2, SO2/CO2/N2, and H2S/CO2/CH4 was considered, because the three mixtures are extensively involved in many industrial processes. The experimental results demonstrated that [DEA]Cl exhibited excellent ability to separate the mixture of NH3/N2/H2. The [DEA]Cl also exhibited the proper capacity to separate SO2/CO2/N2, but the capacity of [DEA]Cl for the separation of H2S/CO2/CH4 was inferior. The theoretical calculations revealed that NH2+ and OH worked synergistically to contribute to the ability of [DEA]Cl for excellent separation of NH3 from NH3/N2/H2, with Cl− contributing to the proper separation of SO2 from SO2/CO2/N2. This study provides experimental and theoretical basis for the industrial application of [DEA]Cl in the area of gas separation.

AbstractThe circular saw blade, which is mainly composed of carbon steel, is used to cut the stone. However, the carbon steel is easily corroded in stone processing wastewater, shortening its lifespan. In this study, a new composite inhibitor of sodium nitrite, sodium molybdate, sodium silicate, sodium tungstate, and sodium citrate was investigated firstly, and then, its inhibition efficiency for carbon steel in stone processing wastewater was explored using electrochemical measurements and weight loss measurements. The results showed that the composite inhibitor as a mixed‐type inhibitor displayed good inhibitory performance. Surface analysis including scanning electron microscope, atomic force microscope, X‐ray photoelectron spectroscopy analysis, and contact angle test further revealed the form of protection of the steel surface by composite corrosion inhibitors. The prepared composite inhibitor exhibited excellent corrosion resistance for carbon steel in stone processing wastewater, and it is believed that the composite inhibitor has certain application potential in industries.

Published: August 2023

AbstractIn space exploration activities, a large amount of materials needs to be carried, which limits the sustainable development of exploration activities. In‐situ resource utilization (ISRU) is an important means to realize resource recycling and continuous space exploration, which converts space resources into oxygen and hydrocarbon fuels. The traditional ISRU in outer space mainly uses high temperature and high pressure to electrolyze water or reduce CO2, having problems such as low conversion efficiency, high energy consumption, and excessive equipment volume. Here, an electrochemical catalytic synthesis technology based on a microfluidic device is proposed, which can convert H2O and CO2 into O2 and organic matter by electrocatalytic method at room temperature and achieve efficient energy and matter conversion. The gas‐liquid mixing and electrochemical reaction were analyzed. A mathematical model of gas‐liquid two‐phase mixing and microfluidic chemical reaction was established. The research results demonstrate the reliability and efficiency of the microfluidic reaction device designed in this paper for ISRU.

Published: August 2023

AbstractDual‐ion batteries have been considered as a competitive energy‐storage device. However, owing to the lack of suitable high‐capacity density and rapid‐charging electrode materials, designing a cost‐effective and high‐performance dual‐ion battery is still a great challenge. Herein, an ultrahigh‐capacity dual‐ion battery is constructed based on a carbon‐nanotubes (CNTs) containing SnS2‐MoS2@CNTs heterojunction anode and highly crystalline free‐standing graphite paper serves as cathode. The SnS2‐MoS2@CNTs heterojunction consisting of ultrathin nanosheets was prepared via a facile two‐step hydrothermal method and shows flower‐like morphology and high crystallinity. Benefiting from the unique design concept, the graphite paper/SnS2‐MoS2@CNTs dual‐ion battery delivers a high capacity of 274.2 mAh g−1 at 100 mA g−1 and has an outstanding capacity retention of 95 % after 300 cycles under 400 mA g−1. Even at a high current density of 2 A g−1 the battery still retains a considerable capacity of 112.3 mAh g−1. More importantly, the battery shows an extremely low self‐discharge of 0.006 % h−1 after resting for 24 h. Characterization using SEM and XRD further demonstrate the excellent cycling stability and good reversibility. Consequently, this constructed dual‐ion battery could be a promising energy storage device and provide new insights for the design of high‐performance dual‐ion batteries.

Published: August 2023

AbstractBackgroundResearchers are increasingly being called upon to involve people with dementia in research that pertains to them. Participatory Action Research (PAR) has been one of the approaches that has been utilized to do this. How people understand and apply the ideas behind this approach however has often been atheoretical and diverse. This has implications for how purpose, power, voice and agency are conceived and actualized.ObjectivesThis paper will examine how theoretical construction of PAR can inform the process of meaningfully involving people living with dementia in research. Specifically, drawing on the work of Paulo Freire, this paper will articulate a way of conceptualizing PAR that is explicitly critical and then demonstrate how these ideas informed a PAR study focused on addressing stigma and discrimination with people living with dementia.ConclusionThe purpose of the paper is to engage researchers and people with lived expertise in critical reflection of what it actually means to involve people with dementia in research.

AbstractObjectiveTo investigate the efficacy of transvaginal cerclage in twin pregnancies with cervical shortening, and to narrow the threshold cervical length for transvaginal cerclage.MethodsThis is a prospective cohort study and 177 twin pregnancies with asymptomatic cervical dilatation or cervical length of 15 mm or less between 16+0 and 25+6 weeks of pregnancy were included. Patients independently chose either transvaginal cerclage (n = 129) or no cerclage treatment (n = 48) after being consulted on the risk and potential benefit of transvaginal cerclage. The primary outcome measures were gestational age at delivery and neonatal survival rate.ResultsCompared with the no cerclage group, the cerclage group exhibited a higher gestational age at delivery (32.1 ± 4.5 vs 28.3 ± 6.2 weeks, P < 0.001) and a higher neonatal survival rate (86.4% vs 47.9%, P < 0.001). Subgroup analysis showed that in twin pregnancies with cervical dilatation or cervical length less than 10 mm, the cerclage group had significantly higher gestational age at delivery (31.3 ± 4.6 vs 23.4 ± 4.3 weeks, P < 0.001) and a higher neonatal survival rate (123 [85.4%] vs 4 [9.1%], P < 0.001) than the no cerclage group, but in twins when cervical length was 10–15 mm, the two measures were similar between the two groups.ConclusionTransvaginal cerclage may provide benefits for twins when cervical dilatation or cervical length is less than 10 mm, but its efficacy might not extend to twins when the cervical length is 10–15 mm. Further evidence is needed to confirm the efficacy of transvaginal cerclage for twin pregnancies with a short cervix.
