ABSTRACTThe rational use of autoclaved starches in food applications is difficult because there is a lack of information on their structure–functionality relationship. The novelty of this research relies on disclosing such an association. Hylon V starch was autoclaved at 105, 120, and 135°C to investigate its crystalline and double‐helical features and its relationship with functionality. In autoclaved Hylon V starch, interactions of amylopectin and amylose improved while the crystalline regions decreased. The degree of double helices (DD) decreased after autoclaving at 105°C and the degree of order (DO) increased after treatment at 120 and 135°C. The water solubility index (WSI) (4.63–6.38%) and swelling power (SP) (4.39–7.1 g/g) increased when the temperature increased. On the other hand, water (103.49–225.01%) and oil (61.91–94.53%) holding capacity (WHC and OHC, respectively) increased after autoclaving treatment, although the values decreased with the treatment intensity. The functional properties were affected when the structure changed as a function of the treatment temperatures. PCA analysis showed that WSI and SP of autoclaved Hylon V starch were associated with a high DD, with better compaction, and with stronger amylopectin–amylose interactions. WHC and OHC were associated with better crystallinity, stronger interactions of amylopectin and amylose, and heterogeneous double‐helical crystallites. These findings are useful for understanding the structure–functionality relationship of autoclaved Hylon V starch and pave the way for future research regarding the effects of its incorporation on the properties of food matrices such as bread, yogurt, cakes, and pudding.

AbstractAs greener strategies become the top priority of all nations, their contributions toward decarbonized economies arise as an important topic. The present study attempts to weigh the effect of such strategies. We investigate this relationship using panel regressions and applying many tests based on data gathered from 2010 to 2019. Our findings underscore the positive impact of adopting green initiatives on mitigating environmental pollution. Specifically, we demonstrate that renewable energy consumption serves as a vital substitute for traditional energy sources in G7 nations, offering significant opportunities for private sector involvement in sustainable energy ventures. However, green finance initiatives exhibit positive outcomes while certain aspects of economic development exert detrimental consequences on environmental conditions.The current study is useful for environmental protection agencies, organizations, analysts, policymakers, and the private sector, as the role of green finance and energy efficiency is highly manifested. By channeling and reallocating appropriate funds to green projects, including those led by private enterprises, G7 countries can proactively address environmental degradation and align with the objectives outlined in the Paris Agreement.

AbstractIntroductionTumor genomic testing (TGT) is standard‐of‐care for most patients with advanced/metastatic cancer. Despite established guidelines, patient education prior to TGT is frequently omitted. The purpose of this study was to evaluate the impact of a concise 4 min video for patient education prior to TGT.MethodsBased on a quality improvement cycle, an animated video was created to be applicable to any cancer type, incorporating culturally diverse images, available in English and Spanish. Patients undergoing standard‐of‐care TGT were enrolled at a tertiary academic institution and completed survey instruments prior to video viewing (T1) and immediately post‐viewing (T2). Instruments included: (1) 10‐question objective genomic knowledge; (2) 10‐question video message‐specific knowledge; (3) 11‐question Trust in Provider; (4) attitudes regarding TGT.ResultsA total of 150 participants were enrolled. For the primary objective, there was a significant increase in video message‐specific knowledge (median 10 point increase; p < 0.0001) with no significant change in genomic knowledge/understanding (p = 0.89) or trust in physician/provider (p = 0.59). Results for five questions significantly improved, including the likelihood of TGT impact on treatment decision, incidental germline findings, and cost of testing. Improvement in video message‐specific knowledge was consistent across demographic groups, including age, income, and education.ConclusionsA concise, 3–4 min, broadly applicable video incorporating culturally diverse images administered prior to TGT significantly improved video message‐specific knowledge across all demographic groups. This resource is publicly available at http://www.tumor‐testing.com, with a goal to efficiently educate and empower patients regarding TGT while addressing guidelines within the flow of clinical practice.

AbstractTetraclinis articulata (Vahl) Mast. is native to the Mediterranean area and belongs to Cupressaceae family. The aim of this study were: i) to determine the chemical composition of essential oils (EOs) of T. articulata obtained from its stems, leaves, and cones using GC coupled to GC/MS; II) to evaluate their antioxidant activity using non enzymatic (DPPH, ABTS and FRAP) and enzymatic methods (catalase activity); III) to evaluated their anti‐enzymatic activity on enzyme involved in metabolism and Central Nervous System using spectrophotometric assays. α‐Pinene, limonene, and bornyl acetate were the main components of the three EOs. Moreover, the EO from cones showed the best antioxidant activity and was also to increase of catalase activity. All EOs were active against α‐amylase in similar way; the EO leaves was more active against α‐glucosidase and the EO from cones was more active against cholinesterase. The EOs demonstrated significant inhibition of the mature biofilm of Gram‐negative and Gram‐positive strains. This highlight the potential uses of T. articulata EOs in the fields of health and agriculture.

AbstractBackgroundFractional flow reserve (FFR) has emerged as the invasive gold standard for assessing vessel‐specific ischemia. However, FFR measurements are influenced by the hydrostatic effect, which might adversely impact the assessment of ischemia.AimsThis study aimed to investigate the impact of hydrostatic pressure on FFR measurements by correcting for the height and comparing FFR with [15O]H2O positron emission tomography (PET)‐derived relative flow reserve (RFR).MethodsThe 206 patients were included in this analysis. Patients underwent coronary computed tomography angiography (CCTA), [15O]H2O PET, and invasive coronary angiography with routine FFR in every epicardial artery. Height differences between the aortic guiding catheter and distal pressure sensor were quantified on CCTA images. An FFR ≤ 0.80 was considered significant.ResultsThe study found a reclassification in 7% of the coronary arteries. Notably, 11% of left anterior descending (LAD) arteries were reclassified from hemodynamically significant to nonsignificant. Conversely, 6% of left circumflex (Cx) arteries were reclassified from nonsignificant to significant. After correcting for the hydrostatic pressure effect, the correlation between FFR and PET‐derived RFR increased significantly from r = 0.720 to r = 0.786 (p = 0.009). The average magnitude of correction was +0.05 FFR units in the LAD, −0.03 in the Cx, and −0.02 in the right coronary artery.ConclusionHydrostatic pressure has a small but clinically relevant influence on FFR measurements obtained with a pressure wire. Correcting for this hydrostatic error significantly enhances the correlation between FFR and PET‐derived RFR.

AbstractBackgroundBleeding and stroke are frequent complications after transcatheter aortic valve implantation (TAVI). The mortality risk associated with these events has been reported before, but data regarding their impact on health‐related quality of life (QoL) is limited.AimTo evaluate the impact of bleeding and stroke occurring within 30 days after TAVI, on mortality and QoL during the first year after TAVI.MethodsPOPular TAVI was a randomized clinical trial that evaluated the addition of clopidogrel to aspirin or oral anticoagulation in patients undergoing TAVI. Besides clinical outcomes, QoL was assessed using the Short Form‐12 and EuroQoL Five Dimensions questionnaires before, and at 3, 6, and 12 months after TAVI.ResultsMajor or life‐threatening bleeding occurred in 81 patients (8.3%) and was associated with an increased risk of death (hazard ratio [HR] 1.95 [95% confidence interval (CI) 1.00–3.79]); minor bleeding occurred in 104 patients (10.6%) and was not associated with mortality (HR 0.75 [95% CI 0.30–1.89]). Stroke occurred in 35 patients (3.6%) and was associated with an increased risk of death (HR 2.90 [95% CI 1.23–6.83]). Mean mental component summary (MCS‐12) scores over time were lower in patients with major or life‐threatening bleeding (p = 0.01), and similar in patients with minor bleeding, compared to patients without bleeding; mean physical component summary (PCS‐12) scores, EQ‐5D index, and visual analog scale (VAS) were similar between those patients. Mean MCS‐12 scores were lower in patients with stroke (p = 0.01), mean PCS‐12, EQ‐5D index, and VAS were similar compared to patients without stroke.ConclusionMajor or life‐threatening bleeding and stroke were associated with an increased risk of death and decreased mental QoL in the first year after TAVI.

Authors: NOSBUSCH Patrick , SCIAN Ettore , DE CILLIA Andrea 
Published: September 2024

AbstractThe new railway line connecting Luxembourg and Bettembourg crosses the A3 highway at a steep angle (19.5°) with the bridge called OA14.The designed bridge is a bowstring structure with a single span of 186.85 meters. The bridge deck consists of two lateral metal box girders acting as a chord. The deck is a transversal filler beam, with spherical voids and lightweight concrete to reduce the structure's weight.The bridge features two inward‐inclined arches at 9°, which are doubled and serve as trusses. This significantly increases the stiffness of the arch whilst keeping the silhouette elegant. The deck follows the curved track alignment, the arches remain straight. Two times 12 hangers connect the arches to the girders, they are made of CHS profiles of S450H quality. This article gives an overview of the structure and its construction. It then gives a more detailed insight in the design of the hangers, especially the hanger‐girder connections.

Authors: Krouský Jiří 
Published: September 2024

AbstractThe railway bridge in Prague under Vyšehrad is a steel riveted structure with a lower deck from 1901 connecting the right and left banks of the Vltava River. The bridge is double‐track and is located on a national track included in the TEN‐T system. This is the transit corridor Nuremberg – Pilsen – Prague – Brno – (Vienna, Bratislava, Poland). It is therefore one of the busiest railway bridges in the Czech Republic. The bridge is a cultural monument.At the moment, it is also the best‐known and most discussed railway bridge in the Czech Republic. The bridge has been in service for more than 120 years and its expected lifespan has long been exceeded. The railway needs to increase the track capacity. At the same time, it is being discussed what to do with the heritage‐protected bridge. Repair? Replace? Shift? These are the questions and challenges facing the Railway Administration.

Preliminary design of a viaduct on new Highspeed line RS2 VRT Jižní Morava
Authors: Franko Samuel , Hukel Martin 
Published: September 2024

AbstractThe newly proposed high‐speed rail in Czech Republic creates a set of new challenges for engineers in design overall. In this case, the most significant challenge was to design a viaduct over several obstacles due to the crossing of Special Area of Conservation (SAC), part of Natura 2000. This aims to limit impacts in short‐term, during construction and more importantly in the long term. Construction of the viaduct will mitigate an impact to the natural surrounding area, whilst allowing immigration of its natural habitats. Nevertheless, the viaduct design and operational speeds will reach 320 km/h with possible raising to 350 km/h limit, with minimal impact within the area.Initial length of the viaduct was over 1 300 m and the main requirement given by an infrastructure manager was to design a viaduct without railway expansion joints. Due to such a long distance, the viaduct had to be separated into several dilatation segments in order to avoid the use of rail expansion joint. The most susceptible parts of SAC were in proximity of the river Šatava and surrounding wetlands. This area created an obstacle, which had to be crossed by a long span avoiding the implementation of bridge piers. Poor geological conditions close to the watercourse had to be taken into consideration for design of pier foundation, therefore the span had to be shortened to a compromised length.The final design of the viaduct consists of 16 segments, of which 14 are continuous segments and 4 are single spans. Overall, there are 29 spans over the length of the viaduct. Construction method of incremental launching had been chosen to reduce the short‐term impact in the SAC.
More durable modular expansion joint constructions for road bridges
Authors: Ungermann Dieter , Brune Bettina , Diener Michael 
Published: September 2024

AbstractRelevant aspects in the design of modular expansion joints are the high fatigue stress caused by heavy load traffic and the corrosion protection. Currently, corrosion damage is often not limited to the traversable surface. Therefore, more durable expansion joints are highly desirable to extend their service life. The FOSTA research project P1574 resulted from the need for durable expansion joints and thus is aimed at hot‐dip galvanized structures. In this project about 14.000 individual damages on 6.300 modular expansion joints were evaluated, relevant hot‐dip‐galvanizing parameters were investigated and recommendations for hot‐dip galvanizing‐compatible constructions were made. In addition, the fatigue strength of existing constructions has been evaluated with regard to the current and upcoming version of Eurocode 1993‐1‐9. This evaluation will be verified in the course of cyclic tests and numerical investigations. A monitoring concept is to be designed according to the requirements of the modular expansion joints and the corresponding neuralgic points.
THE NEW PEDESTRIAN FOOTBRIDGE AT LUXEMBOURG RAILWAY STATION
Authors: DE CILLIA Andrea , BORBOUX Thomas , LUONGO Eric 
Published: September 2024

AbstractThe new pedestrian footbridge at Luxembourg Train Station is an integral component of the revamped platform canopies. Its unique undulating wave design, symbolic of motion, is mirrored in the canopies' roofs, creating asynchronous waves between platforms. As the footbridge aligns with the wave, it gracefully encompasses the translucent tube of the new structure.An integrated staircase fits beneath this architectural wave, with an elevator opposite for easy platform access. This translucent prism stands in stark contrast to the sweeping curves of the roofs and the footbridge itself.Prioritizing user comfort and safety, a translucent design was chosen, eliminating blind spots. The 100‐meter footbridge is constructed with an orthotropic steel deck, offering substantial spans with minimal height. The roof's central section serves to reduce sun exposure and conceal electrical wiring.The assembly process involved crane work during railway track closures over consecutive weekends, using a CC3800 crane with a maximum capacity of 650 tons

Authors: Freymann Konrad 
Published: September 2024

AbstractOnce constructed, the Baku White City pedestrian bridge will be a landmark for the newly developed White City district in the east of the Capital. Designed by UNStudio, the bridge crosses the highway of 8th November Avenue and connects the newly build city to the seaside, forming a wide promenade.Due to the pending construction of the mall as future bridge support, the bridge had to be redesigned. A cantilevering viewing platform will highlight the bridge's ending.This paper covers the structural design of the architecturally shaped cable stayed bridge, supported through a 46 m high A‐shaped, slightly curved pylon. Based on 3‐D modelling in Rhino® and Grasshopper®, the FE‐software SOFISTIK® is used both for cable force finding and bridge design.The structural system, steel structure's specific detail for cable connection and its design approach have been documented.
Steel Arch Structures with Prestressed Concrete Deck
Authors: Strasky Jiri 
Published: September 2024

AbstractFootbridges with prestressed concrete deck, which are suspended on steel arch ribs, are described in terms of the structural arrangement, static function and erection. These bridges create stiff structural systems which guarantee the bridges' favourable dynamic response. While steel arch ribs allow easy erections, the concrete deck guarantees structural integrity. The footbridges are structurally efficient, they are light and transparent, corresponds to the scale of the landscape and all structural members have human dimensions. They were erected with a minimum impact on the environment. Their structural arrangement is illustrated on examples of four bridges.
Remaining Fatigue Strength of an Orthotropic Steel Deck with Respect to a Repair Method by Cold Joining Techniques

Published: September 2024

AbstractThe increased traffic loads of the last decades led to an overload of the existing infrastructure. Especially for orthotropic steel decks of bridges, which are prone to fatigue fractures, this have led to structural damages of different categories. With respect to category 2 damages and their retrofit, this paper presents results of fatigue tests on the nonwelded constructional details of an old, demolished orthotropic steel deck. The samples were extracted from a highway bridge with an orthotropic steel deck built in Germany in the 1970s. In comparative fatigue tests on identical constructional details made of new material with the same steel grade, the remaining fatigue strength was determined. Based on the problem of manganese sulfides in old steels the potential of the repair method by cold joining techniques was emphasized. Characteristic load‐bearing capacities for a Eurocode 3‐compliant design of a structural blind fastener were determined and their use in a pilot project was reported.

Authors: Koščo Tomáš , Margetin Matúš , Chmelko Vladimír 
Published: September 2024

AbstractBridges, as public structures, are national infrastructure structures. The investment requirements and demands for safe operation should put them at the forefront of engineers' attention. The important SNP bridge in Bratislava (Slovakia), which is one of the first bridges in the world to be suspended entirely on cables, has been the subject of a diagnosis of its health after 50 years of operation. The article describes and documents the individual steps of this diagnostics ‐ identification of the rope material, the status of the rope material and its current strength properties, and the experimentally and computationally determination of the forces in the individual ropes and their cables. The uniqueness of all the diagnostic steps was that they were carried out directly in the outdoor conditions of full operation of the bridge. The achieved results are briefly documented in the paper. Conclusions and further necessary steps for the final comprehensive safety assessment of the bridge operation are formulated.
Analysis of bow‐string arch using geometric data from 3D scanning
Authors: Odrobiňák Jaroslav , Farbák Matúš , Chromčák Jakub , Gocál Jozef 
Published: September 2024

AbstractThe utilization of currently measured geometric data for analysis of arch bridges and their stability is discussed. The presented contribution follows a set of research activities focused on real values of geometric imperfections of a steel bow‐string arch bridge using 3D scanning. Relatively new railway arch bridge with span 124.8 m is discussed. Deviations from the theoretical design shape of the arch were recorded during the erection stage and after a proof‐load test of the bridge, as well. Thus, it was possible to observe if and how the geometric imperfection changes during construction. Numerical models were created to perform geometrically nonlinear analysis. Both theoretical and real imperfections obtained by 3D scanning were considered in the analysis to compare and quantify the influence of the actual deformed shape. Finally, the obtained data, their comparison, the applicability of the presented methods, and possible pitfalls of the procedure are discussed.
