Authors: Fernandez Nicolas , Zuluaga Laura , Paris Gabriela , Norato María Juana , Silva José Miguel , Pérez Jaime 
Published: June 2022

Abstract
Objective Research on gender dysphoria (GD) has been growing over the last decades with increasing interest in understanding and characterizing the causal relationships between psychological, genetics, hormonal, and sociocultural factors. Changes and acceptance of this condition as non-pathologic have led to significant changes in general perspective and its management over time. Our objective is to carry out a bibliometric analysis to know the publication trends and quality of evidence related to gender dysphoria.
Methods A systematic search and critical review of the literature was carried out between January 1900 and December 2018 to perform a bibliometric analysis. Research was done in the following databases: OVID, PubMed, EMBASE, Scopus, Web of Science and Google Scholar. The medical subject headings (MeSh) terms used were: gender dysphoria; and surgery and psychology. The results were plotted using the VOSviewer version 1.6.8. Statistical analyses were performed with the IBM SPSS, Version 25.0.
Results A total of 1,239 manuscripts were identified, out of which 1,041 were selected. The average number of cited times per year per manuscript is 1.84 (interquartile range [IQR] 0-2.33). The average impact index was 47.8 (IQR 20-111.6). The median of total citations per manuscript was 3 (IQR 0-33.1), and the highest number of citations per manuscript was 484. Most publications focus on the psychological aspects of GD, and there is a significant amount of manuscripts related to social and anthropological issues. Most articles have a low level of scientific evidence.
Conclusion There is a great amount of published literature on GD; however, there is a significant level of disagreement in many respects on this topic. Regarding surgical gender-affirmation, there is a lack of information supported by high level of evidence to uphold the emerging expansion of medical practices.
Comparative Study of Cytokeratin Immunostaining of Parotid Gland Parenchyma in Normal, Diabetic, and Excretory Duct Ligation of Mongrel Dogs
Authors: Hassan Sherif Sayed , Alqahtani Mashael Saeed 
Published: June 2022

Abstract
Objectives The present study aimed to give a glimpse of the normal distribution of intermediate filaments within the parotid gland parenchyma of mongrel dogs and to reveal the pathological changes that may occur as a result of the effects of diabetes mellitus or atrophy of the gland caused by the ligation of the excretory duct to discover whether there is a similarity in these pathological behaviors.
Materials and Methods Twelve healthy mongrel dogs were used in the experiment and were divided into three groups: group I (the control group), group II (dogs with alloxan-induced diabetes), and group III (dogs with the right-side duct-ligated parotid gland). The dogs were sacrificed 45 days after the parotid excretory duct were tied. The right parotid gland of all groups was dissected and prepared for histological and immunohistochemical expression of cytokeratin 17 assay.
Results Histological findings confirmed that the parotid gland parenchyma of the diabetic group had glandular atrophy characterized by the loss of gland structure, degenerated acini, and dilatation of the duct system. Moreover, there is a predominance of the fibrous component with the presence of fat cells within the gland compartments. On the contrary, the excretory duct-ligated group undergoes severe glandular atrophy of the previous character with the presence of duct-like structure as well as extravasation and vasodilatation. Immunohistochemical expression of cytokeratin 17 in control parotid using an immunoperoxidase technique showed that cytokeratin expression varies from negative to mild in all ducts and some serous acinar cells. The gland parenchyma of the diabetic group showed mild to strong cytokeratin expression of duct cells more concentrated in the apical part with moderate to strong expression of diffuse type in some serous acini. The intensity of cytokeratin 17 in gland compartments of the excretory duct-ligated group revealed a variation in expression that ranged from negative to strong diffuse staining throughout the gland.
Conclusion The severity and prevalence of cytokeratin 17 in our results are predictive of the pathological influence of both diabetes mellitus and duct ligation on the cytokeratin intracellular filaments of the salivary gland parenchyma in a different way that interferes with saliva production and/or secretion leading to xerostomia.

The knowledge of both parameters significantly reduces the number of free parameters of the model and thus improves the accuracy of kinetic predictions. The results of the kinetic model are compared with the measured emission spectra of the second positive system and the Herman infrared system of N2. The use of the sensitivity analysis method leads to a better understanding of the role of specific elementary processes in the APTD mechanism and also to the determination of the density of the two lowest vibrational levels of N2(

Abstract
At present, the concept of bridge preventive maintenance has been widely used. In order to find the right time for PC bridge maintenance and make better maintenance decision, it is necessary to predict the service performance of PC bridge. In this paper, the service performance of PC bridge is divided into several indexes, and the fuzzy neural network method is used to calculate these indexes data. Taking shangtan bridge as an example, the maximum relative error between the measured value and the predicted value is found to be within 5%, which meets the accuracy requirements. The feasibility of this method is verified and provides guidance for the future decision-making of bridge maintenanc.

In laboratory, the leakage data under various working conditions are measured through the water supply network model. It is input into SAA-SVM model as sample data set for optimizing the model by machine learning. The results show that the optimized SAA-SVM can predict the leakage shape and loss quickly and accurately.

Authors: Ke Yanyu , Shen Guohui , Yu Hangcong , Xie Jiming 
Published: June 2022

Abstract
The wind-induced response of tall buildings is usually dominated by dynamic across-wind vortex shedding. The intensity of vortex shedding depends on not only the model configurations but also the turbulence around the structure. The building models with different configurations including chamfer, crown opening, and porous crown were tested in different turbulent conditions. The 10% chamfered ratio has a more considerable benefit in suppressing the intensity of vortex shedding compared with the 7.5% chamfered ratio. The slotted crown has a more beneficial effect in suppressing the wind-induced responses due to resonance caused by vortex shedding compared with the one without opening. The model with 50% crown porosity has a more considerable benefit in suppressing the intensity of vortex shedding compared with the solid crown. The model with turbulent condition both the suburban exposure and interference of surroundings has a more considerable benefit in disrupting the vortex shedding compared with the model in open exposure without interference.

Abstract
In recent years, China has entered a period of rapid development of urban rail transit construction. Building information modeling technology (BIM) has been widely used in the design stage of urban rail transit engineering, but there is a waste of BIM design resources, and there is a lack of scientific and systematic BIM technology application mode and management methods. Based on this, this article summarizes six BIM application modes that are prone to problems in design and contributes greatly to construction, and summarizes the work content, management methods and application effects of each application mode. Then, we investigated the charging situation of the aforementioned BIM application mode for subway projects of five domestic companies, which provided a reference for the choice of BIM application mode. Finally, combined with the construction of Tianjin Line 5, it is demonstrated that the use of BIM aided design list management can maximize the application of BIM technology to value points in the design stage under the condition of limited construction capital investment, which can effectively improve the effect of BIM application, Capital utilization rate and project management level.

Authors: Zhang Ping 
Published: June 2022

Abstract
As a result of urban land shortage and saturation, the development and construction of underground parking have become an inevitable trend of current social development. This paper describes both the concept and construction necessity of underground parking system by analyzing the current status of the parking situation in urban central business district (CBD). According to several case studies for the building of underground parking system around the world, four different layouts such as ridge-like, ring, radial, and network for underground parking systems are proposed. The internal channel of an underground parking system consists of primary and secondary channels and the internal channel setting of the underground parking system is directly related to the organization of the internal traffic flow. The setting of underground vehicle lanes and underground parking units in the system is considered to determine the internal traffic organization of four layout modes of an underground parking system. The findings of this research provide both theoretical and technical support for the planning and design of underground parking system.

Abstract
Faced with the problems of existing buildings in cold areas, such as poor insulation performance of envelope, high heating cost and substandard indoor temperature in winter, based on DeST-h energy consumption simulation software, taking typical single buildings in Zhangjiakou as an example, several factors affecting building energy consumption were analyzed. The building energy consumption values in heating season under 9 envelope reconstruction conditions were obtained by orthogonal experiments, and 4 different energy supply systems were designed for buildings under 9 envelope reconstruction conditions. The “with or without comparison method” is used to evaluate the building energy efficiency of 40 working conditions after the superposition of the initial state and passive transformation of existing buildings in the whole life cycle. The evaluation results show that the external wall insulation and extrusion plate thickness is 80 mm, the roof insulation and extrusion plate thickness is 100 mm, and the glass type is ordinary hollow glass ( 6 + 9 + 6 ). The air source heat pump assisted energy supply effect is the best, but the overall economy will change with the initial investment, local electricity price policy and building scale.
The fundamental studies on the reaction kinetics of thermal decomposition of bio-composite based backsheet materials in photovoltaic (PV) panel
Authors: Zulkeply M , Pang M M , Vaithilingam C A , Sivasubramanian R 
Published: June 2022

Abstract
This research presents the reaction kinetics of thermal decomposition of vetiver filled Polylactic Acid (PLA) bio-composite based backsheet in Photovoltaic (PV) panel via the Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The conventional PV backsheet called TEDLAR (Polyvinyl Fluoride, PVF) is made from petroleum, a non-biodegradable material which will impose serious problems to the environment at the end-of-life of the PV modules. Therefore, it is important to identify the suitability of PLA/vetiver to replace TEDLAR. The best composition of PLA/vetiver producing the lowest thermal degradation is discussed by analysing the activation energy of the bio-composites with different weight percent (wt. %) of PLA/vetiver. The result showed the wt. % of PLA/vetiver with lower content of the natural fibre has a lower thermal degradation temperature which indicates the rapid start of the degradation process. However, TEDLAR degrades at an average temperature of 400°C proving the ability to withstand extreme temperatures, thus it does not degrade easily. The results showed the higher the content of the vetiver, the lower the degradation temperature. The activation energy of the bio-composites was calculated using the Kissinger method and the estimation values of the different doses of PLA/vetiver range between 28 to 77 kJ/mol.

Authors: Chong K V R , Hoon Y , Ahmad H 
Published: June 2022

Abstract
Power quality (PQ) is one of the main issues faced in the present era. The PQ issues such as voltage sags, swells, harmonics, and unbalance as well as the impact on sensitive loads are often occurred in any power distribution system. To tackle the issues, a powerful dynamic voltage restorer (DVR) is commonly installed. However, the existing control algorithms for DVR are found to be complex, potentially increases computational burden to the controller. Therefore, in this paper, a new simplified control algorithm which utilizes the strengths of synchronous rotating frame (SRF) and phase-locked loop (PLL) concepts, is proposed to better manage operation of DVR. The DVR system is modelled and simulated by using MATLAB/Simulink platform. Performance of the newly proposed algorithm for DVR is tested in three-phase system with voltage sags, swells, harmonics and unbalances conditions. From the findings, it can be concluded that the proposed algorithm for DVR which installed in a three-phase power distribution system effectively mitigated the voltage sags, swells and unbalances conditions and, for harmonics condition, it is found to be able to minimize and contain the harmonic contents within the acceptable level.

Published: June 2022

Abstract
Glass microspheres are gaining attention in bone tissue engineering due to their ability to convert into hydroxyapatite-like materials, resembling the inorganic mineral of natural bone. The morphology of glass microspheres as starting material has been considered to influence the conversion rate and the resulting product where porous microspheres could promote faster conversion to hydroxyapatite than solid microspheres. This paper reports on manufacturing glass microspheres (solid and porous) using a flame spheroidisation process. The effect of various gas ratios of acetylene and oxygen on the morphological changes of glass microspheres was investigated. Irregular shaped glass particles with starting particle size ranges of 63 – 125 μm were used as feed and delivered to a hot flame to produce solid microspheres. To manufacture porous glass microspheres via a single-stage flame spheroidisation process, calcium carbonate was utilised as a porogen and mixed with the glass particles. Solid and porous glass microspheres were successfully produced, exploring various gas ratios of 3:3, 4:7, 5:7 and 6:7 with a mean particle size range between 73 – 105 μm. Moreover, the average pore size of 6 μm and 9 μm was obtained using 5:7 and 6:7 gas ratios, respectively. This single-stage flame spheroidisation process is a promising method for producing both solid and porous bioactive glass microspheres.
The Effects of Physical and Geometrical Properties on Rock Brittleness Index Based on Numerical Modeling

Published: June 2022

Abstract
Rock brittleness is a key parameter to quantify and evaluate the brittle nature of the rock. A better estimating technique of rock brittleness is crucial for acquiring an efficient stimulation of unconventional shale gas reservoirs such as hydraulic fracturing. One way to predict rock brittleness index is by using rock elastic moduli. These physical properties highly depend on the complexity of the microstructure, fluid content, and mineral composition. The other way is by measuring the rock mineral composition itself. This complexity of the microstructure can be accurately characterized by using imaging techniques such as micro-CT scans. This study used the finite element method to estimate rock brittleness index based on elastic properties on synthetic and digital rock images. We then evaluate the effect of physical and geometrical properties (pore aspect ratio, water saturation, and mineral composition) in determining the rock brittleness characteristic. The results indicate that there is an increase in Young’s modulus along with an increasing pore aspect ratio to 1, which in turn raises the rock brittleness. Fluid saturation, in this case, water saturation, causes brittleness to be increased. The rock mineral composition, such as abundant quartz and carbonate content, yields high brittleness values, while high clay content and porosity lower the rock brittleness. Overall, the results imply that pore geometry, fluid saturation, and mineral composition significantly alter the rock strength parameters.

Abstract
The Lombok earthquake in July 2018 caused considerable damage to public facilities and residential areas. Most of the houses in the north of the island of Lombok were damaged by the 6.9 magnitude earthquake. We want to know what parameters cause houses and buildings in North Lombok not to experience a severe liquefaction process. We used near-surface tomographic resistivity imaging to characterize the subsurface of North Lombok to map the subsurface of the most affected areas in North Lombok. The geological condition of northern Lombok is the most vulnerable area to liquefaction due to volcanic loose sand layers, shallow groundwater, and thick deposits. However, almost all subsurface images from resistivity tomography from North Lombok show limestone layers at shallow depths, which may play an important role as a protective layer from liquefaction phenomena in this area.
