Objective The aim of this study is to determine parents' knowledge levels and attitudes about childhood human papillomavirus (HPV) vaccination and reveal the differences between parents who are health care workers and nonhealth care workers. The HPV vaccine can potentially prevent initial HPV infection and HPV-related genital and anal precancerous disorders and cancers.

Methods Questions and attitudes toward childhood HPV vaccination were asked to 564 parents who agreed to participate in the study.

Results In our study, the rate of health care worker parents considering having their children vaccinated against HPV (63.1%) was higher than that of nonhealth care worker parents (11.4%). Only 5% of parents had their children previously vaccinated against HPV; however, there was no difference between parents who were health care workers and those who were not. In addition, this rate was relatively low compared to other paid vaccines (49.8, 35.3, and 18.8%, respectively). Parents who had not previously vaccinated their children against HPV were considering getting their children vaccinated, especially if a pediatrician recommended it.

Conclusion The parents' high level of health literacy may not be effective in deciding to vaccinate their children against HPV. Therefore, adequate information and awareness should be provided to all parents about HPV vaccination as early as possible for all children of appropriate age. Pediatricians should be given important roles in raising the awareness of parents about childhood HPV vaccination by health authorities.
CO2 capture using dicationic ionic liquids (DILs): Molecular dynamics and DFT-IR studies on the role of cations
Authors: Torkzadeh Mehrangiz , Moosavi Majid
Published: December 2022

Dicationic ionic liquids (DILs) have been shown to be useful as an effective solvent for the absorption of CO2. However, compared to monocationic ionic liquids (MILs), they have been less investigated for this application. Previous studies on MIL–CO2 systems have shown that anions play the main role in tuning CO2 capture, but the partial negative charge on the oxygens of CO2 may interact with cation centers and, especially, for DILs with two charge centers, the role of cations can be significant. Therefore, the current work focuses on how cation symmetry and the length of side chains affect interactions and also the dynamical and structural properties of DIL–CO2 systems using molecular dynamics simulation. In addition, the effect of CO2 on the infrared vibrational spectra of isolated ions and ion triplet (DIL molecules) was studied using density functional theory calculations and the observed red and blue shifts have been interpreted. The results indicated that symmetric cation with longer side chains tend to interact more strongly with CO2 molecules. It seems that increasing the length of the side chains causes more bending of the middle chain, and in addition to increasing the free fraction volume, it weakens the interaction between cations and anions, and as a result more interaction between gas and cation. The results of this work may contribute to the rational molecular design of DILs for CO2 capture, DIL-based gas sensors, etc.
A spur to molecular geometry optimization: Gradient-enhanced universal kriging with on-the-fly adaptive ab initio prior mean functions in curvilinear coordinates
Authors: Teng Chong , Huang Daniel , Bao Junwei Lucas
Published: December 2022

We present a molecular geometry optimization algorithm based on the gradient-enhanced universal kriging (GEUK) formalism with ab initio prior mean functions, which incorporates prior physical knowledge to surrogate-based optimization. In this formalism, we have demonstrated the advantage of allowing the prior mean functions to be adaptive during geometry optimization over a pre-fixed choice of prior functions. Our implementation is general and flexible in two senses. First, the optimizations on the surrogate surface can be in both Cartesian coordinates and curvilinear coordinates. We explore four representative curvilinear coordinates in this work, including the redundant Coulombic coordinates, the redundant internal coordinates, the non-redundant delocalized internal coordinates, and the non-redundant hybrid delocalized internal Z-matrix coordinates. We show that our GEUK optimizer accelerates geometry optimization as compared to conventional non-surrogate-based optimizers in internal coordinates. We further showcase the power of the GEUK with on-the-fly adaptive priors for efficient optimizations of challenging molecules (Criegee intermediates) with a high-accuracy electronic structure method (the coupled-cluster method). Second, we present the usage of internal coordinates under the complete curvilinear scheme. A complete curvilinear scheme performs both surrogate potential-energy surface (PES) fitting and structure optimization entirely in the curvilinear coordinates. Our benchmark indicates that the complete curvilinear scheme significantly reduces the cost of structure minimization on the surrogate compared to the incomplete curvilinear scheme, which fits the surrogate PES in curvilinear coordinates partially and optimizes a structure in Cartesian coordinates through curvilinear coordinates via the chain rule.
ARHGAP17 regulates the spatiotemporal activity of Cdc42 at invadopodia

Published: December 2022

Invadopodia formation is regulated by Rho GTPases. However, the molecular mechanisms that control Rho GTPase signaling at invadopodia remain poorly understood. Here, we have identified ARHGAP17, a Cdc42-specific RhoGAP, as a key regulator of invadopodia in breast cancer cells and characterized a novel ARHGAP17-mediated signaling pathway that controls the spatiotemporal activity of Cdc42 during invadopodia turnover. Our results show that during invadopodia assembly, ARHGAP17 localizes to the invadopodia ring and restricts the activity of Cdc42 to the invadopodia core, where it promotes invadopodia growth. Invadopodia disassembly starts when ARHGAP17 translocates from the invadopodia ring to the core, in a process that is mediated by its interaction with the Cdc42 effector CIP4. Once at the core, ARHGAP17 inactivates Cdc42 to promote invadopodia disassembly. Our results in invadopodia provide new insights into the coordinated transition between the activation and inactivation of Rho GTPases.

Published: December 2022

Functional recovery after incomplete spinal cord injury depends on the effective rewiring of neuronal circuits. Here, we show that selective chemogenetic activation of either corticospinal projection neurons or intraspinal relay neurons alone led to anatomically restricted plasticity and little functional recovery. In contrast, coordinated stimulation of both supraspinal centers and spinal relay stations resulted in marked and circuit-specific enhancement of neuronal rewiring, shortened EMG latencies, and improved locomotor recovery.
The First Photometric and Spectroscopic Study of Contact Binary V2840 Cygni

Published: December 2022

The first photometric, spectroscopic and period variation studies of neglected short-period eclipsing binary V2840 Cygni are presented. High mass ratio contact binaries (HMRCBs), especially those in the weak-contact configuration, are vital when probing the evolutionary models of contact binaries (CBs) using stellar parameters. The photometric solutions reveal the weak-contact nature of V2840 Cygni with a high mass ratio (∼1.36), motivating us to investigate the nature of such binaries. The period variation study of V2840 Cygni spanning 15 yr shows a secular period decrease at a rate of ∼5.5 × 10−7day yr−1, indicating mass transfer between the components. The superimposed cyclic variation provides a basic understanding of the possible third body (P3∼ 8 yr,m3∼ 0.51M⊙). Following the derived parameters, the evolution of the system is discussed based on the thermal relaxation oscillation (TRO) model. It is found that V2840 Cygni falls in a special category of HMRCBs, which validates TRO. To characterize the nature of HMRCBs, a catalog of 59 CBs with high mass ratios has been compiled along with their derived parameters from the literature. For all the HMRCBs in the study, a possible correlation between their contact configuration and observed period variations for relative logJrelis discussed. The spectroscopic study of V2840 Cygni provides evidence of the presence of magnetic activity in the system and the existence of ongoing mass transfer which is additionally deduced from the period variation study. The LAMOST spectra of 17 HMRCBs are collected to interpret the stellar magnetic activity in such systems.

We report a candidate tidal disruption event (TDE) found in the Zwicky Transient Facility survey data. This candidate, with its transient name AT2021acak, showed brightness increases of ∼1 mag around MJD 59500 and subsequent power-law–like brightness declines. We have conducted multiple optical spectroscopic observations with the 2.4 m Lijiang telescope and one observation at X-ray and ultraviolet (UV) bands with the Neil Gehrels Swift Observatory (Swift). The optical spectra of the source show broad H and He emission lines and Fe emission features. Possible 0.3–2 keV X-ray and bright UV emission of the source was detected. We analyze the declines of the optical light curves, the emission features of the optical spectra, and the constructed broad-band UV and optical spectra. The properties derived from the analyses are consistent with those of reported (candidate) TDEs, and in particular very similar to those of ASASSN-18jd. The identification is complicated by the host being likely an AGN, and thus further observations of the event and quiescent host are required in order to have a clear understanding of the nature of this transient event.

Machine learning algorithms can study existing data to perform specific tasks. One of the well-known machine learning algorithms is the backpropagation algorithm, but this algorithm often provides poor convergence speed in the training process and a long training time. The purpose of this study is to optimize the standard backpropagation algorithm using the Beale-Powell conjugate gradient algorithm so that the training time needed to achieve convergence is not too long, which later can be used as a reference and information for solving predictive problems. The Beale-Powell conjugate gradient algorithm can solve unlimited optimization problems and is much more efficient than gradient descent-based algorithms such as standard backpropagation. The research data used for the analysis were formal education participation data in Indonesia. To be trained and tested using the 7-10-1 architecture. The results showed that the Beale-Powell Conjugate Gradient algorithm could more quickly perform the training and convergence process. However, the MSE value of testing and performance is still superior to the backpropagation algorithm. So it can be concluded that for the prediction case of Formal Education Participation in Indonesia, the Conjugate Gradient Beale-Powell algorithm is good enough to optimize the performance of backpropagation standards seen from the convergence speed and training performance.

The construction industry is one industry that contributes significantly to a country’s economic growth. A construction project is successful if the implementation meets the three components namely the cost, time and quality. Project financing is one of the important components in the construction project activities that define how much budget should be provided in a construction project activity. Cost components used for feasibility studies, design alternatives are possible, and the selection of optimal design in a construction project. Inaccuracy in analyzing construction costs can have a negative effect on the entire construction process and all parties involved. A system dynamics approach is a simulation method in solving real-world problems to describe relationships among variables in complex real systems. The expected results from this research are quantitatively in the form of reinforced concrete work costs which are influenced by direct costs and indirect costs that can be updated in real-time. From the simulation results, a graphical analysis through the model output will be obtained and all the resulting scenarios can be compared. In addition, with sensitivity analysis through model scenarios, it can accommodate all possible deviations that will occur in the future, including risk factors in the future.

Increasing the Compressive Strength of Concrete Using PPC
Authors: Ginting Arusmalem
Published: December 2022

Cement factories in Indonesia rarely produce OPC due to the high cost of production and less environmentally friendly, so they prefer to produce PPC or PCC. Cement factories located in areas that are rich in natural pozzolan will prefer producing PPC. In general, there is an assumption that increasing the compressive strength of concrete using PPC is slow at the early age. Based on these assumptions, it is necessary to conduct research on increasing the compressive strength of concrete using PPC at an early age. The specimen used was a concrete cylinder, with 3 specimens for each variation. The compressive strength test of concrete is carried out at the ages of: 3, 7, 14, 21, and 28 days. From the research results obtained, compressive strength of concrete has increased with increasing age of the concrete. The increasing the compressive strength of concrete using PPC is comparable with concrete using OPC. The unit weight of concrete is almost the same for all ages of concrete.

A boiler is one of the most significant components in a steam power plant system, as steam from the boiler is used to crank a steam turbine, which drives an electric generator. A sootblower is a piece of boiler equipment that cleans the ash and scale that has built up on the pipes. The heat-transfer pipes have been reduced. When soot builds up on the pipes or the riser on the boiler’s walls, heat transfer is impeded, resulting in less heat transfer. The amount of steam produced by the boiler will decrease if the heat transfer is lowered. Heat transfer is small in superheaters, reheaters, economizers, and air heaters, as well as in heat recovery regions like superheaters, reheaters, economizers, and air heaters. as well as the pipes for the superheater, reheater, economizer, and air heater As a result, the main objective of the sootblower is to analyze it so that lost energy in the boiler can be reduced. It also enhances the boiler’s efficiency once the sootblower has been employed.

Published: December 2022

ross flow turbines are widely used as turbines for driving micro-scale hydropower plants in rural areas, but their efficiency is still low because cross flow turbines only use one nozzle. The utilization of the potential energy of water is not optimal yet to be converted into pressure and kinetic energy of water in the nozzles with high water velocity hitting the turbine blades. The problem of cross flow turbines with one nozzle has an uneven flow of water to the turbine blades, and it is not effective in converting potential energy into power in the turbine. The purpose of this research is to develop a four-nozzle Cross Flow turbine and test its performance. The method used is to conduct experimental testing in a laboratory that tests the performance of a cross flow turbine using four nozzles. A cross flow turbine with four nozzles has better performance than a cross flow turbine using only one nozzle. The results obtained that the cross flow turbine with four nozzles where the water jets out of the nozzle is more evenly distributed and the flow of water enters the turbine blade runner, resulting in a good impulse reaction in the blades. The conclusion is that the performance of the four nozzle cross flow turbine is able to produce higher turbine rotation, power and efficiency.

This is a quantitative research with the purposive sampling method used to collect data from 6 relevant stakeholders and policymakers through questionnaires. The criteria reviewed are the building condition, age, and area, as well as the total number of stalls, traders, transactions, and population. The data analysis technique used descriptive statistics and Multi-Criteria Analysis (MCA). These results showed that the dominant criteria that need to be considered in the maintenance and care of permanent market buildings are the building conditions with an average criterion weight value of 0.35. Additionally, the first, second, third and fourth priorities were given to Lambaro Pilot Market, Indrapuri Lama, Krueng Raya, and Lambada with alternative performance (Pi) values of 9.00, 5.69, 5.63, and 5.10, respectively.

In the field of transportation, one of the technological developments can be found in the parking service system. However, in the current parking service system, there are still several shortcomings, one of which is the absence of a parking system that can provide information to motorists regarding vacant parking locations. If the condition of the parking lot is congested, it will be difficult for customers to find an empty parking location and cause queues at the parking location. The purpose of this study is to design a system for calculating the availability of parking spaces that can make it easier for motorists to find an empty parking area so that the mobility of vehicles in the parking lot can be organized, efficient, and well organized. This smart parking system is designed using an Arduino microcontroller and uses an infrared sensor to detect the condition of the car in the parking lot. The information provided in the form of parking conditions will be displayed through the LCD and the LabView application so that the information can be known by the driver before entering the parking area. In addition, drivers can also find out the number of parking fees for their vehicles. Results of the simulation show that the prototype can work normally according to the design made.

Published: December 2022

University campuses have a long history of enriching the social, cultural, and economic value of societies. Worldwide, there is a rising demand for the integration of new approaches into the planning and design of university buildings to further improve their quality. According to the literature, many approaches needed to be considered while designing university buildings that can enhance students’ performance. Biophilic design is known to have enhancing levels of interaction, and interaction patterns, enhancing health and wellbeing in terms of physiological, psychological, cognitive, and social/ spiritual benefits, while rigorous scientific evidence that supports such claims is rare. Many researchers have previously investigated the application of biophilic elements in working environments, however limited research is related to university building designs, specifically in Egypt. There is limited research on methods for quantifying the effect of biophilic design patterns on the physiological, and cognitive benefit. Thus, in light of the concept of Biophilia, this research aims to identify the correlations between the biophilic patterns and enhancing student performance. Survey questionnaires were administrated to a sample of students who regularly use the selected drawing studio. The extracted data will be analyzed through the use of SPSS software. This paper will benefit researchers who are interested in this field and may serve as a suitable beginning point for them and designers as well as a guideline while designing a university using biophilic patterns.

Published: December 2022

Recent economic and population growth patterns in Egypt almost guarantee that energy consumption and emissions will continue to rise rapidly if nothing changes. According to the United Nations Development Program, Egypt’s energy demand will have been triple by 2030. Additionally, Egypt’s total emissions from energy use have been increased eightfold since 1971. The construction industry has been pushed to adopt sustainable building strategies, and the consensus among researchers and practitioners is that the most important phase to make decisions about is during the early stages of design. Arguably, high-performance buildings require a different design mechanism than traditional methods to achieve a holistic, sustainable outcome. Indeed, Building Information Modelling (BIM) can greatly facilitate the informed sustainability in buildings. Although BIM and sustainable design emerge from different underlying factors, they share an important common thread: the success of both depends on large part of building design philosophy loaded from the start. In fact, BIM can greatly facilitate the informed sustainability in buildings. Within the framework of reviewing the literature, researchers concluded the importance of BIM in the early stages of building design. The authors conducted an applied case study to evaluate a residential building in the new Administrative Capital in Cairo, Egypt, and concluded a set of design upgrades to raise the energy efficiency of the building and reduce carbon emissions from operating energy.

Published: December 2022

Sustainability is the goal pursued by societies worldwide. Existing buildings have had their share of those issues, specifically healthcare buildings, as most governments encourage green new construction and neglect existing buildings. Additionally, the benefits of existing buildings in preserving the environment, and its resources and reducing energy and global warming crises. The research objective is to achieve a high-level performance of existing healthcare buildings within a framework of evaluating the most important determinants affecting these buildings.

The paper will focus on presenting the different rating systems such as LEED and BREEAM, by dividing and analyzing these systems, given that each system has its own standards and how it scores evaluation points. As the rating systems help in improving the existing healthcare buildings and get low-negative environmental impacts; they will reduce pollution, reduce carbon emissions, choose non-polluting and sustainable materials, encourage the use of recycled materials, and control waste management.

The paper presents an approach to find out which rating system will evaluate green existing healthcare.
