Key Clinical MessageSubacute thyroiditis which is typically characterized by cervical pain and fever is caused by viral infection and is seen after SARS‐CoV‐2 vaccination. Here we report a post‐vaccination subacute thyroiditis after SARS‐CoV‐2 vaccination.AbstractSubacute thyroiditis (SAT) is possibly caused by a viral infection and is typically characterized by cervical pain and fever. SAT associated with SARS‐CoV‐2 infection or SARS‐CoV‐2 vaccination has been reported, albeit in limited numbers. A 34‐year‐old woman was referred to our clinic with typical SAT symptoms. The diagnosis was confirmed through thyroid scintigraphy after receiving the SARS‐CoV‐2 vaccination, despite testing negative for COVID‐19 via RT‐PCR. There is a theoretical correlation between SARS‐CoV‐2 vaccination and SAT. Vaccination may have a direct or indirect impact on the thyroid, but further studies are required to confirm this relationship. A systematic review of the literature of similar cases was performed for comparison. Ultimately, the overall benefits of SARS‐CoV‐2 vaccination outweigh the potential adverse effects. Therefore, these types of reports should not divert attention from the actual reality.

Key clinical messageIn a rare occurrence, primary varicella infection led to rhabdomyolysis in a 24‐year‐old with no medical history. Presenting with rash, fever, and weakness, he developed diffuse myalgia at 72 h. Elevated muscle enzymes confirmed rhabdomyolysis secondary to varicella zoster virus (VZV) infection. Treatment with acyclovir and hydration resulted in significant improvement within a month.AbstractPrimary varicella infection is rarely complicated by rhabdomyolysis. In this study, we describe a case of rhabdomyolysis complicating a VZV infection in a black subject. The patient was a 24‐year‐old black African with no particular medical history and was immunocompetent. He presented with an acute onset of generalized rash, fever, and generalized weakness. Physical examination revealed vesicular lesions typical of chickenpox. Antipyretic treatment combined with acyclovir was instituted in hospital. At the 72nd hour, diffuse myalgia developed. Muscle enzyme tests revealed CPK elevated to 40 times the upper limit of normal, LDH elevated to 2 times the upper limit of normal, ASAT and ALAT elevated to 7 times the upper limit of normal, and 2.5 times the upper limit of normal, respectively. We accepted the diagnosis of rhabdomyolysis secondary to VZV infection. The patient was given saline hydration and showed clinical and biological improvement 1 month later. A patient presenting with muscular symptoms during a VZV infection should be considered for rhabdomyolysis.
Physiotherapy intervention in Smith–Magenis syndrome: A case report based on exercise therapy for postural control and balance
Authors: López‐Torres Adriana , Naia‐Entonado Zeltia 
Published: March 2024

Key Clinical MessageThis case report aims to raise a physiotherapy intervention for subjects with SMS. The basis is an active work, based on postural control and balance training. Physiotherapists can play an important role in the management of these subjects.AbstractSmith–Magenis syndrome (SMS) is a genetic alteration that encompasses a series of psychophysical repercussions that interferes with postural control and the autonomous functionality of the subjects who suffer from it. In this study, a clinical case of an 18‐year‐old adolescent with a genetic diagnosis of an SMS mutation is presented. This work proposes a physiotherapy intervention, adapted to the individual conditions and agreed upon with his family. The goal would be to analyze the effectiveness of postural control and balance training in a subject with SMS. A physiotherapy intervention based on postural control and balance was proposed. This approach is combined with the strengthening and readaptation of the antigravity muscles, through strength training, mobilization exercises, gait and transfers reeducation. An initial assessment was carried out. The interventions were developed at the home of the clinical case. The main variables were balance and postural control. For this, the following measurement scales and tests were used: Face Scale, Gross Motor Function Scale, Berg Balance Scale, Romberg Test, Barthel Index, and Functional Assessment of Sitting (SATco scale). After the intervention, the case presented under observation greater postural control in the transfers, less imbalances, and introduced new positions during their development, which allow more functional and autonomous movement. This was also extrapolated to gait, which was optimized in its development. This observation was not reflexed in test scores, which remained the same than the initial assessment. The intervention had a positive effect on the development of trunk control, transfers, and gait.

Published: March 2024

AbstractTo effectively reduce SO2 emissions, flue gas desulfurization methods are widely used in coal‐fired power plants. In desulfurization, the dry sorbent injection (DSI) technology has the advantages of high desulfurization efficiency, simple operation, convenient adjustment, and low initial investment. Here, a pilot‐scale experimental system was designed and built to investigate the desulfurization characteristics of the DSI technology. The influence of the residence time of the desulfurizer, the reaction temperature, the stoichiometric ratio of the desulfurization reaction, the particle size of the desulfurizer, the inlet SO2 concentration, the dust concentration, and the water vapor content in the flue gas on the desulfurization efficiency at low SO2 concentrations was studied by injecting NaHCO3 into the pipeline. The desulfurization efficiency can be significantly improved by reducing the desulfurizer particle size or increasing the water vapor content in the flue gas at low SO2 concentration. An empirical formula describing the dependence of the desulfurization efficiency on experimental parameters is given.
Lithium Metal Anode in Electrochemical Perspective
Authors: Wang Leping , Wu Feng , Yao Ying , Zhang Cunzhong 
Published: March 2024

AbstractLithium metal is a possible anode material for building high energy density secondary batteries, but its problems during cycling have hindered the commercialization of lithium metal secondary batteries. Until now, many sophisticated techniques have been used to obtain rich micro‐morphological and physicochemical information of the deposition layer and the solid electrolyte interface (SEI), and to develop improvement strategies based on the information and achieve remarkable results. Regulating the reaction process around key links is a classic strategy to achieve expected results. Based on this empirical fact, we artificially highlighted the differences in the apparent performance of lithium metal anode using different series of electrolytes. We used microelectrode technology to analyze the reaction mechanisms and kinetic characteristics of each elementary step under all electrolyte conditions, revealing common laws that affect apparent performance and the basic steps that have a decisive impact on apparent performance. We discussed and elucidated the relevant physical and chemical principles, providing a clear basis for improving the pertinence and efficiency of improvement strategies.

Authors: Reiners Jochen , Zehfuß Jochen , Dehn Frank , Müller Christoph 
Published: March 2024

AbstractThis paper summarizes the results of two research projects that were carried out between 2016 and 2022 at the VDZ (Verein Deutscher Zementwerke) in Düsseldorf. The objective of the projects was to examine the influence of the cement type as well as the physical and chemical properties of the hardened cement paste on the explosive spalling of concrete in the case of fire. A particular focus was set on studying the way in which the concrete's moisture content contributes to the spalling phenomenon. The findings obtained for the different concretes examined in the dedicated experimental program were evaluated to better explain the mechanisms causing the heat‐induced explosive spalling of concrete.
COMPARATIVE STUDY BETWEEN SHELL AND SOLID FINITE ELEMENT MODELS FOR STEEL JOINTS CHARACTERIZATION
Authors: Aguiar J. , Freire F. , Santos A. F. , Ljubinković F. , Conde J. , da Silva L. S. 
Published: March 2024

AbstractSolid and shell finite element models (FEM) are two commonly used possibilities to analyse the structural behaviour of steel joints. The choice between solid and shell models often comes down to a balance between computational resources and the level of detail required for the study. In this paper, a set of welded beam‐column joints with hot‐rolled open sections is studied using both modelling techniques. The joints' behaviour is assessed in terms of resistance and initial stiffness. An improved shell FEM is proposed. The results indicate that for the studied dataset, both techniques return comparable results. Hence, the use of shell FEM seems to be a possible alternative to solid FEM and can be efficiently used for the joint characterization.
RECTANGULAR HOLLOW T‐SHAPED JOINT WITH ECCENTRICITY MADE OF HIGH STRENGTH STEELS
Authors: Kalmykova Svitlana , Wald František 
Published: March 2024

AbstractThe presented research aims to investigate how the choice of steel grade affects the resistance of T‐shaped RHS‐to‐RHS structural connections, specifically those involving an offset of a brace toward the wall of a chord. To assess the mechanical resistance of these connections, the numerical non‐linear FE modelling with ABAQUS software were utilized, which is then validated against results obtained from the analytical model developed by Kalmykova & Wald [1]. Material modelling is carried out for steel grades S355, S460, and S690, using standardized parametric curves as outlined in EN 1993‐1‐8. It is evident that variations in material properties and the fy/fu ratio influence the behavior of these connections, particularly at the 3% deformation level.

Authors: Tesch Luana , Gervásio Helena , Craveiro Hélder D. 
Published: March 2024

AbstractWood is a popular material in civil engineering due to its renewability and ability to store carbon during the growing in forests. However, the LCA of wood‐based materials is currently based on the balance of carbon without considering the dynamic changes of forests over time and the effects of climate change, like wildfires, on this balance. Hence, this paper is the first step towards the development of a dynamic LCA of forests considering climate change effects on the carbon balance of forests. The paper focusses on the life cycle analysis of sandwich panels with a core made of wood fibers, based on current databases, and aims to illustrate the importance of biogenic carbon in the whole life cycle of such panels, particularly when compared with other traditional panels.
NUMERICAL MODELING OF TIMBER‐STEEL HYBRID STRUCTURES: CHALLENGES AND INNOVATIVE STRATEGIES
Authors: Corti Laura , Muciaccia Giovanni 
Published: March 2024

AbstractThe increasing diffusion of timber as a structural material asks for major detailing concerning numerical modelling; timber is commonly used with other construction materials in order to create hybrid structures exploiting each material's strengths and smoothing less efficient features. In this way – combining timber and steel – structural performances are guaranteed while lightness and sustainability of only‐timber structures are maintained. Some specific issues linked to timber material – e.g., orthotropic behaviour – and contact with steel are specifically addressed, exploring different techniques according to the scale of the problem. Finally, a complete steel‐timber hybrid beam‐to‐column joint is assembled, with a clear understanding of each interaction and insights for future adjustments to the benchmark model.
SCOPE 3 CARBON EMISSIONS IN SEAPORTS
Authors: Freitas Danielle , Gervásio Helena 
Published: March 2024

AbstractGrowing concern about carbon emissions and their environmental impact has led the port sector to assess and reduce their carbon footprint. Scope 3 mobile source emissions, especially related to maritime transportation, play a significant role in this scenario. This study analyses methodologies and tools for calculating Scope 3 emissions, highlighting the main features and shortcomings through case studies. Among the main identified gaps are the lack of standardization and the limited availability of port data. Digitization and its integration with a universal approach present an opportunity for more accurate calculations and a more effective development of emission reduction strategies.

Authors: de Souza Jorge Maurício , Oliveira Amanda Borges , Moreira Lucas Suzano , da Silva José Guilherme Santos 
Published: March 2024

AbstractThis research work aims to contribute to structural designers based on the development of a probabilistic approach for evaluating the dynamic structural response of pedestrian footbridges, with regard to excessive vibrations that may cause human discomfort. Based on the use of probabilistic methods, it becomes possible to determine the probability of the structure's peak acceleration values exceeding or not the human comfort criteria. The results obtained in this investigation reveal that the values of maximum accelerations, calculated based on the deterministic methods may be overestimated in design situations.
BUILT‐UP COLD‐FORMED STEEL‐LIGHTWEIGHT CONCRETE (CFS‐LWC) COMPOSITE BEAMS SUBJECTED TO ELEVATED TEMPERATURES
Authors: Rahnavard R. , Craveiro H.D. , Simões R.A. , Santiago A. , Laím L. , Gardner L. 
Published: March 2024

AbstractCold‐formed steel (CFS) products are extremely versatile and can be used in multiple applications. Recent experiments tests by the authors have shown that mobilising composite action within systems comprising cold‐formed steel beams and lightweight concrete is feasible and can lead to substantial improvements in structural performance. However, their behaviour subjected to elevated temperatures has yet to be investigated; this is, therefore, the focus of the present study. The results of two tests on CFS‐LWC beams at ambient and elevated temperatures are reported. A numerical modelling study using fire dynamics simulator (FDS) software is then described in which the temperature development was successfully replicated.
EFFECTIVE MODULUS METHOD (EMM) CONCEPT APPLIED TO THIN‐WALLED STEEL BEAMS AFFECTED BY LOCAL‐DISTORTIONAL INTERACTION
Authors: Prola Luís , Gala Pedro , Ruben Rui B. , Monteiro Cristiano , Simões Ana 
Published: March 2024

AbstractThe Effective Modulus Method (EMM), which simulates the effects of local and distortional post‐buckling to establish simplified design methodologies concept, is applied to the determination of the beam strength. This methodology was presented before [1], where the authors tested the results in columns, in comparison with experimental tests. In this approach, local and distortional post‐buckling effects are simulated by changing the mechanical characteristics (namely the elasticity modulus) of the cross‐section of the members. Specifically, the paper presents (i) the proposal of a new design methodology for beams affected by local and distortional buckling modes interaction and (ii) the comparison with experimental tests available in the literature.

Resistance of thin sheets lap joints connected by spot welding and brazing
Authors: Ungureanu Viorel , Both Ioan , Cristian Antonio Andrei 
Published: March 2024

AbstractThe results of an experimental program on lap joints of thin gauge sheets connected by spot welding and MIG brazing are compared to the design code provisions. The results show the dependency of the spot weld lap joints resistance on the thickness of the connected sheets, while the MIG brazed lap joints resistance depends on the minimum thickness of the steel sheets connected. A statistical interpretation of the results shows the accuracy of the joint resistance. The coefficient of variation of the spot weld specimen is smaller than the one for the MIG brazed specimen, while the resistance of the spot weld is higher than the MIG brazed specimen when compared to the nominal resistances.

Published: March 2024

AbstractThe mechanical behaviour of adhesively bonded point‐fixings, in the scope of glazing systems, are usually investigated by non‐linear finite element analysis (FEA). The accuracy of the finite element model depends on the availability of suitable experimental data, used to calibrate the material models that describe the appropriate behaviour of the adhesive material. This paper presents and discusses the outputs of an experimental campaign focused on characterizing the mechanical properties on bulk material of the structural adhesive Sikasil® SG‐500, a bi‐component structural silicone. The results of the experimental campaign are used to calibrate material models for finite element analysis. The best‐performing hyperplastic material models for the state of stresses analysed in this paper, are selected and presented, intended to be used by designers and engineers.

Authors: Saeed Haroon A. M. , Xu Weilin , Yang Hongjun 
Published: March 2024

AbstractThe world's population is growing, leading to an increasing demand for freshwater resources for drinking, sanitation, agriculture, and industry. Interfacial solar steam generation (ISSG) can solve many problems, such as mitigating the power crisis, minimizing water pollution, and improving the purification and desalination of seawater, rivers/lakes, and wastewater. Cellulosic materials are a viable and ecologically sound technique for capturing solar energy that is adaptable to a range of applications. This review paper aims to provide an overview of current advancements in the field of cellulose‐based materials ISSG devices, specifically focusing on their applications in water purification and desalination. This paper examines the cellulose‐based materials ISSG system and evaluates the effectiveness of various cellulosic materials, such as cellulose nanofibers derived from different sources, carbonized wood materials, and two‐dimensional (2D) and 3D cellulosic‐based materials from various sources, as well as advanced cellulosic materials, including bacterial cellulose and cellulose membranes obtained from agricultural and industrial cellulose wastes. The focus is on exploring the potential applications of these materials in ISSG devices for water desalination, purification, and treatment. The function, advantages, and disadvantages of cellulosic materials in the performance of ISSG devices were also deliberated throughout our discussion. In addition, the potential and suggested methods for enhancing the utilization of cellulose‐based materials in the field of ISSG systems for water desalination, purification, and treatment were also emphasized.
