The features of the process of teaching Russian as a foreign language using modern online technologies are considered. The main components of the organization of the learning process of the teacher in the mode of synchronous and asynchronous communication and the classification of online services and online resources for language learning, including an overview of applications for the organization of the learning process are presented. The author points out the relationship of goals and features of the educational process with the chosen method of teaching and the main components of the educational process aimed at building a flexible learning model focused on the optimal learning material acquisition by students when teaching Russian as a foreign language. The relevance of this topic is due to a number of factors of modern reality, which point to the importance and necessity of applying new technologies and teaching methods in the traditional educational process.
Las homilías Adversus Iudaeos de Juan Crisóstomo: temas y estrategias argumentativas polémicas
Authors: Simonassi Lyon Andrea
Published: October 2021

Mientras fue presbítero de Antioquía entre 386 y 398 –año en que fue nombrado Patriarca de Constantinopla–, Juan Crisóstomo, representante del cristianismo niceno, tuvo una prolífica carrera como predicador en las iglesias más importantes de la ciudad. Fue conocido como “boca de oro” por sus dotes en retórica y son muchas las obras homiléticas que se adjudican a su período antioqueno, entre las que podemos citar su serie conocida como Adversus Iudaeos. Pronunciada entre los años 386 y 387, tiene como objeto atacar a aquellos cristianos que participan de festividades judías y asisten a la sinagoga. Pero no son sólo ellos los que sufrirán el embate del presbítero: a lo largo de su serie, vemos cómo arremete contra los judíos, la Sinagoga, la Ley mosaica y las fiestas judías. El presente artículo se propone rastrear y discutir los epítetos y críticas pronunciados por Crisóstomo en las homilías Adversus Iudaeos en contra de los judíos y sus principales instituciones y festividades, así como contra aquellos miembros de su congregación que compartían, asistían a y participaban de sus fiestas, y recurrían a los “especialistas en lo sagrado” judíos para obtener curas o solucionar problemas.

Modelling Anisotropic Phenomena of Friction of Deep-Drawing Quality Steel Sheets Using Artificial Neural Networks
Authors: Trzepieciński Tomasz , Lemu Hirpa G. , Chodoła Łukasz , Ficek Daniel , Szczęsny Ireneusz
Published: October 2021

This paper presents a method of determining the coefficient of friction in metal forming using multilayer perceptron based on experimental data obtained from the pin-on-disk tribometer. As test material, deep-drawing quality DC01, DC03 and DC05 steel sheets were used. The experimental results show that the coefficient of friction depends on the measured angle from the rolling direction and corresponds to the surface topography. The number of input variables of the artificial neural network was optimized using genetic algorithms. In this process, surface parameters of the sheet, sheet material parameters, friction conditions and pressure force were used as input parameters to train the artificial neural network. Some of the obtained results have pointed out that genetic algorithm can successfully be applied to optimize the training set. The trained multilayer perceptron predicted the value of the friction coefficient for the DC04 sheet. It was found that the tested steel sheet exhibits anisotropic tribological properties. The highest values of the coefficient of friction under dry friction conditions were registered for sheet DC05, which had the lowest value of the yield stress. Prediction results of coefficient of friction by multilayer perceptron were in qualitative and quantitative agreement with the experimental ones.

Published: October 2021

Introduction: Primary squamous cell carcinoma (SCC) and adenosquamous carcinoma of the pancreas are rare malignancies for which diagnostic and treatment strategy are challenging. In this paper we present a literature review of these tumors based on two case reports.

Case presentation: In the first case, a 55-year-old male presented with an inoperable pancreatic head/body junction tumor. Endoscopic ultrasound-guided fine needle aspiration was practiced, and histopathological examination revealed a squamous cell carcinoma of the pancreas. After exclusion of any another tumor, the diagnosis of cT4N0M0-staged primary pancreatic SCC was made. The patient is under treatment with gemcitabine and oxaliplatin. The second case is represented by a 73-year-old patient in which imagistic examinations highlighted a cystic mass of the pancreatic body. Following coporeo-caudal splenic-pancreatectomy and histopathological-proved diagnosis of adenosquamous carcinoma, the patient started chemotherapy but died at 11 months after surgery. Both tumor components displayed positivity for markers which prove ductal (cytokeratin19, maspin) and squamous differentiation (p63, cytokeratin5/6) same as vimentin, as indicator of epithelial mesenchymal transition (EMT).

Conclusions: SCC and adenosquamous carcinoma of the pancreas are aggressive malignancies which prognosis remains highly reserved. These tumors might be variants of ductal adenocarcinomas which are dedifferentiated through EMT phenomenon.

Published: October 2021

Objectives: Taking into account that the documentation of the histopathological features in severe disease caused by SARS-CoV-2 has been scarce due to the avoidance of performing autopsies, the aim of the study was to detect the microscopic changes associated with severe COVID-19 infection in normal-appearing skin, without prominent dermatologic signs of a generalized microvascular thrombotic disorder, in accordance with the clinical evolution of disease.

Methods: In this morphological and immunohistochemical study we included cutaneous biopsy samples from 12 symptomatic patients with severe and critical type SARS-CoV-2 infection (with the admission date between February and June 2020), treated in the Intensive Therapy Unit Care of Emergency County Hospital Targu-Mures, Romania.

Results: The average age of our patients was 65.18 ± 14.21 years (range 41 to 83), and 66.67% of the patients were male. The histological and immunohistochemical assessment of cutaneous biopsies: in 4 cases the histological examination revealed small fibrin thrombi in deep-seated venules and small veins of subcuticular adipose tissue, and also 4 cutaneous biopsies showed occlusive vascular thrombosis in association with massive perivascular inflammatory infiltrate destroying and compromising the integrity of the vessel wall. The immunohistochemical examination of the composition of perivascular inflammatory infiltrate showed a predominance of CD3 positive lymphocytes, admixed with CD68 positive Mo/ MF, some of them activated with FXIII expression. In the perivascular infiltrate, the presence of granulocytes and B lymphocytes was not characteristic.

Conclusion: According to our observations, in severe COVID-19, the cutaneous tissue is involved even in the absence of clinically obvious changes. Due to the relatively easy accessibility of skin samples, these could be applied to determine the severity of the patient’s clinical status, and to predict the necessity for anti-complement or anticoagulant treatments in the early stages of a severe SARS-CoV-2 infection.
Thyroglossal duct cyst papillary thyroid cancer – the state of the art
Authors: Dabrowska Anna Maria , Dudka Jaroslaw
Published: October 2021

Thyroglossal duct cyst is one of the most common congenital malformations in the neck area. The majority of cysts turn out to be benign tumors, however, 0.7-1.5 % of the remnants develop into carcinoma, with papillary thyroid cancer being the most frequent malignant neoplasm. The origin of the cancer has not been clearly established so far. Typically, thyroglossal duct cyst cancer is an enlarging flexible midline or slightly lateral neck mass, most often without other worrisome symptoms. The proper diagnosis can be difficult due to the rare prevalence of thyroglossal duct cyst papillary thyroid carcinoma, as well as a lack of strongly typical features distinguishing benign and malignant lesions before surgery. Thus, diagnosis is usually made postoperatively just after histopathological examination of a resected cyst. However, there are diagnostic procedures that should be considered before the surgery that may be helpful in making a proper diagnosis. These include fine-needle aspiration biopsy, computed tomography or magnetic resonance imaging. Moreover, there are some characteristics revealed through clinical and ultrasound examination that may suggest the presence of such cancer. While the Sistrunk procedure is often considered adequate, currently, there is no clear consensus about concurrent thyroidectomy or radioiodine therapy. In the article, we sum up the preoperative suggestive factors of cancer, as well as the proposed indications that can be helpful in deciding on the extent of surgery and further management.
Urinary iodine as an important indicator for preeclampsia: a Polish perspective
Authors: Gajewska Katarzyna , Laskowska Marzena , Blazewicz Anna
Published: October 2021

Preeclampsia (PE) is one of the leading causes of perinatal and maternal morbidity. Although subclinical hypothyroidism in pregnancy is one of the established risk factors for PE, the link between iodine deficiency and PE is not fully understood. The aim of our study was to assess urinary iodine concentration (UIC), serum thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), and free thyroxine (fT4) levels in Polish women with PE (PE group, n=78) compared with healthy non-pregnant women (CNP group, n=30), and healthy pregnant women (CP group, n=46). The UIC was determined by inductively coupled plasma mass spectrometry (ICP-MS). Both the mean UIC of 144.6±36.4 μg/L in the CP group and the mean of 125.8±33.6 μg/L in the PE group, respectively, were lower compared to non-pregnant women (149.8±28.8 μg/L), and the difference between the PE and CNP groups was statistically significant. TSH values were the highest in the PE group, while the lowest average level was for the CNP group. The fT3 and fT4 values in the PE group were significantly lower compared to the CNP and CP groups. Despite iodine supplementation during pregnancy, the UIC was lower compared to non-pregnant women, while in women with PE it was at a significantly lower level. To reduce the incidence of possible health complications, proper iodine supplementation and monitoring of the UIC is recommended for pregnant women suffering from PE or at risk of developing PE.

Published: October 2021

The objective of this meta-analysis study was to evaluate the comparative efficacy of empagliflozin (25 mg) with placebo in the treatment and management of type 1 diabetes mellitus. This study is a meta-analysis, so an ethical statement is not required. Different databases and individual journal websites like SCOPUS, Science direct, Cochrane review library etc. were used. The articles were evaluated based on the search and eligibility criteria. A total of five RCTs were incorporated in this meta-analysis. These studies contained a total of 1058 patients, including 526 patients with placebo (or control-treated patients), and 532 patients with empagliflozin (25 mg) treated combination. The mean follow-up time ranged from 7 days to 6 months. Overall, mean reduction in placebo was -0.50% and empa-treated was -0.85%, while the pooled WMD was 3.82 995% CI 1.20 – 5.88, p=0.0001). Regarding urinary glucose excretion, that the pooled WMD was 6.67 (95% CI 4.87-10.14, p=0.001) indicated a significant increase in empa-arm compared to placebo. No heterogeneity was found (I2 – 15.03%). This meta-analysis underlined the therapeutic benefit of empagliflozin as an adjunctive therapy for patients with type 1 diabetes.
Casirivimab and imdevimab as investigational monoclonal antibodies for COVID-19 patients – review of the literature
Authors: Reka Gabriela , Pawlak Angelika , Machowiec Piotr , Maksymowicz Marcela , Piecewicz-Szczesna Halina
Published: October 2021

Casirivimab and imdevimab (REGN-COV-2) are investigational monoclonal antibodies approved in November 2020 by the Food and Drug Administration for emergency use in mild and moderate COVID-19. These two noncompeting human IgG1 monoclonal antibodies can target the receptor-binding domain of the spike protein of SARSCoV-2, prevent its entry into human cells, and reduce viral load. The antibodies can be administered intravenously for mild-to-moderate COVID-19 patients who do not require hospitalization and supplemental oxygen. The purpose of the study is to review the latest available data on COVID-19 treatment using casirivimab and imdevimab. According to recent preclinical studies, the antibody cocktail presents optimal antiviral strength and has the potential to minimize the chances of the virus escaping. It was shown in animal studies that the cocktail reduces the pathological consequences caused by viruses, decreases the number of viruses in the respiratory system, and reduces lung titers and pneumonia symptoms. Casirivimab and imdevimab as a cocktail also prevents the rapid appearance of treatment-resistant mutants. In the clinical trial, REGN-COV-2 decreased viral load, particularly in patients with a non-initiated immune response (serum antibody-negative) and with high viral load at baseline. The adverse effects were comparable in the combined REGN-COV2 dose groups (2.4 g and 8.0 g), as well as in the placebo group. The cocktail caused few and mainly low-grade toxic effects. Casirivimab and imdevimab seem to be effective and safe antiviral therapy for nonhospitalized patients with COVID-19. Further observations and research are extremely necessary to assess the efficacy, security and indications in a wider group of patients.
Pre-Hispanic Nahua Slavery
Authors: Vyšný Peter
Published: October 2021

The article deals with pre-Hispanic Nahua slavery. Based upon an examination of Nahua perception of slavery/slaves, Nahua forms of slavery (apart from the slaves destined for sacrifice there were slaves destined for work) and the social and legal position of Nahua slaves (destined for work) the author concludes that the Nahua institution traditionally called “slavery“ is different from its counterparts known from the history of Occident. Except for slaves destined for sacrifice to the gods which are discussed only briefly in the article, the Nahua slaves (i.e. the slaves destined for work) had a certain degree of personal freedom and certain rights. Becoming a slave at birth was possible only exceptionally and the enslavement of persons was in many cases (even if not in all cases) only temporary. The treatment of Nahua slaves – compared to the living conditions of their counterparts in many other world cultures – was significantly better, more humane. This can be seen from the fact that the master was entitled only to his/her slave’s labor and not to slave’s life, health, family members or property, as well as from the fact that the slave could obtain freedom in many ways, not only by the manumission made by his/her master. Although slaves were considered a kind of both physically and mentally “less perfect“ individuals who were “dirtied“, that is, morally tainted and dishonored by their enslavement and its reasons (mainly a delinquent behavior, i.e. non-payment of debts or perpetration of certain crimes), they were not systematically excluded from the wider society formed by free persons and they lived with their families in their houses and neighborhoods.

Published: October 2021

The Guerrouche forest is home to a fairly important flora heritage which offers this massif a forest cover by the presence of quite remarkable forest stands, from a floristic point of view by the presence of natural vegetation characterized by a diverse flora. This study aims to quantify the floristic diversity of the vegetation associated with the three main tree species (zeen oak, cork oak and afares oak) that inhabit the Guerrouche forest on the basis of distributed floristic surveys, according to a sampling strategy. stratified and systematic, which took into account the species present in each type of tree stand. The floristic surveys thus carried out, numbering 55, made it possible to establish a list of a floristic list made up of 172 species, which belonged to 69 genera and 45 botanical families. Of these, 42 were endemic species, including 4 specific to the study area. The number of rare and very rare species was 70 taxa. The study also revealed the clear degradation of the genus Erica of this ecosystem. Analysis of the overall chorological spectrum showed a dominance of Mediterranean species (209 species), with a dominance (82.3%) of species that were therophyte species. The forest stands of the genus Quercus inhabiting the Guerrouche massif must be supported by the authorities to preserve and conserve this forest heritage against fires, illegal logging, etc. The results of this study will be the subject of development actions and rational management of these natural forest ecosystems.

In this study, the antifungal activity of cell-free supernatant (CFS) of Lactobacillus spp. (Lactobacillus plantarum CCM 1904; L81, Lactobacillus fermentum; 2I3, Lactobacilus reuteri; 2/6, L26;) and Bacillus spp. (Bacillus subtilis CCM 2794, Bacillus licheniformis CCM 2206) against two strains of Fusarium graminearum CCM F-683 and Fusarium graminearum CCM 8244 were investigated in vitro. All tested CFS of Lactobacillus spp. were able to inhibit the growth of both strains of Fusarium graminearum. The highest inhibitory effect (IE) (56.5 %) against F. graminearum CCM F-683 was observed for CFS Lactobacillus fermentum (2I3) at the minimum inhibitory concentration (MIC) (2.25 ± 0.56 mg.ml–1). CFS of Lactobacillus reuteri (2/6) showed the best IE (40.0 %) against F. graminearum CCM 8244 (2/6) at the MIC 1.25 mg.ml–1. However, no inhibitory effect of Bacillus subtilis and Bacillus licheniformis CFS against both strains of F. graminearum were observed, even at the highest tested concentration of 5.0 mg.ml–1.

Published: October 2021

Stress can be a reason for some physiological and biological disorders in the body. The antioxidative defense system is necessary for the maintenance of redox homeostasis in the organisms. Alkaline water (AW) is in the focus of the scientific interest due to its antioxidative effect. The treatment with AW and sodium ascorbate (SA) is expected to have potential preventive effect on the organism to hyperthermic stress. The aim of this study was to investigate the effect of AW and SA on glucose and cortisol levels during acute hyperthermic stress, in white female Wistar laboratory rats. The rats were divided into three groups, each having 10 subjects. They were exposed in hyperthermic conditions (41˚C) for 80 min, in 21 consecutive days in order to induce oxidative stress. The first group received drinkable water (control group), the second AW, and the third, AW and SA. Plasma glucose levels were determined by colorimetric method. Cortisol level was measured by the enzyme-linked immunosorbent assay method (ELISA). The means were compared using the Tukey test. Differences were considered significant at a level of p<0.05. Our results showed that levels of glucose and cortisol were significantly higher in the group treated with AW on the 21st day after treatment (p<0.0001), but not on the 7th and 14th day as compared to the control group. Also, co-treatment of animals with AW and SA had significantly increased the levels of glucose and cortisol on the 21st day after treatment, indicating a synergistic effect. In conclusion, the individual action of AW or in synergism with SA caused a high protective effect on oxidative damage in white Wistar laboratory rats.
Amino acid sequence and side chain specific synthetic receptors targeting protein phosphorylation
Authors:   , Incel Anil
Published: October 2021

Antibodies have become a critical component of many diagnostic assays and are used for therapeutic purposes. Nevertheless they often fail to meet the strict performance demands raised in industry and in the clinic (e.g. stability, reproducibility, selectivity, affinity). These issues are especially notable for assays targeting post translational modifications (PTM) of proteins (phosphorylation, glycosylation, sulfation etc.). Antibody-based technologies suffer from problems of a more general nature associated with the analytical use of biological receptors i.e.: i) limited stability requiring cold chain logistics, ii) high production costs, iii) batch to batch variability. The above emphasizes the need for alternative robust, reproducible and low cost “binders” and assays. The aim in this thesis is to design, develop and test molecularly imprinted polymers (MIPs) which were synthesized epitope and stoichiometric imprinting approaches targeting phosphorylation as a PTM. Protein phosphorylationis one of the most common PTM, which is based on covalent attachment of phosphate group to particular amino acids. Misregulation of phosphorylation process is found related with diseases such as cancer, diabetes, and neurodegeneration. MIPs are synthesized through copolymerization of functional monomers and crosslinkers in the presence of N- and C- terminal protected templates. The key recognition element employed in developed synthetic receptors was 1,3-diaryl urea functionalmonomer 1. This monomer is a potent hydrogen bond donor forming strong cyclichydrogen bonds with oxyanions. Amino acid sequence specific and side chain imprinted binders were prepared targeting phosphorylation on tyrosine (pTyr) and on histidine (pHis). pHis MIP-based approach is proposed as a solution to enrich pHis peptides in the presence of other phosphoesters such as phosphoserine (pSer) in complex mixture without pre-treatment like β-elimination. In pTyr, ZAP-70 (zeta associated 70 kDa protein), which is prognosticator for chronic lymphocytic leukemia (CLL), and pTyr-sequence specific motif Src-SH2 domain were chosen as targets to evaluate regio- or stoichiometric selectivity performance of imprinted polymers. The synthesized polymers are used as effective enrichment tools for target phosphorylated peptides from complex mixture prior to mass spectrometry. Overall, the results demonstrate unique proteomics enrichment tools that link with personalized medicine relying on diagnostic coupled cancer treatment strategies based on kinase inhibitors.
Prejudice Toward Asian American Women: Clothing Influences Stereotypes
Authors: Conrow Angelina R. , Gurung Regan A. R.
Published: October 2021

Clothing type can have a significant impact on the way people are perceived. In this study, we were interested in the effect of business versus casual clothing on the perception of Asian American women, given various stereotypes about them. We used a between-subjects design with a sample of college students from a university in the United States. Participants saw 3 Asian American women (and 1 European American woman to distract from the nature of the study) in either business attire or casual outfits, and rated each woman on a series of descriptors based off various stereotypes of Asian American women. We used the Scale of Anti-Asian American Stereotypes to measure internal prejudice toward Asian Americans and the Ambivalent Sexism Inventory to measure sexism. The Scale of Anti-Asian American stereotypes was a significant covariate, F(4, 233) = 6.09, p < .001, ηp2 = .10. Participants rated models in business attire as less stereotypically Asian, F(1, 239) = 46.56, p < .001, ηp2 = .17, less sexualized, F(1, 239) = 12.91, p < .001, ηp2 = .05, and less invisible, F(1, 239) = 42.01, p < .001, ηp2 = .15. Our results show that stereotypes can indeed be influenced by business attire. It is important to note that future research may be oriented toward changing the attitudes of those who hold harmful stereotypes, rather than the actions (i.e., clothing choices) of the subjects of prejudice.
Transforming Obstacles Into Icons Bridges as Key Elements in Cycling Infrastructure
Authors: Spierings Chris
Published: October 2021

Cycling is deeply embedded in Dutch society and town planning. The latest development is that of bicycle fast lanes. In a country that is largely located in a river delta, with waterways literally everywhere, creating those fast lanes more often than not also requires building one or more bicycle bridges. Ipv Delft is a Dutch bridge design and engineering office, specializing in cycling infrastructure. As such, we have plenty of experience in designing bicycle bridges on bicycle fast lanes. Our integrated design method, which was the basis for the Brief Dutch Design Manual for Bicycle and Pedestrian Bridges (2017) has played a mayor role in creating bicycle bridge designs that not only look good, but are also cost-effective, within budget and adjusted to the requirements of the location, its stakeholders and the bridge users.

Our lecture will focus on several projects that illustrate how we work and why we believe an integrated approach is the way to go.
New Workflows for the Efficient Design and Construction of Architectural Footbridges
Authors: Nugent Peter
Published: October 2021

This paper will provide insight into the use of new workflows for the design and construction of architecturally driven footbridges. One of the key components of the workflows is the use of the Building Habitats object Model (BHoM), an open-source common object definition that is agnostic of any software. The primary use of the BHoM in the workflows is to allow data transfer to and from multiple finite element analysis (FEA) packages. In addition to this, the BHoM Engine is utilised to derive structural models from architectural models. The three projects presented demonstrate the applicability of programmatic workflows to various stages and types of design. A value-added analysis is included to evaluate the direct benefits on projects when implementing such workflows such as automating labour-intensive processes. The analysis also includes the indirect benefits such as the inherently better quality of models, better collaboration with architects and a more efficient design.
Marineda Footbridge in A Coruña (Spain)
Authors: Cascales Fernández Jorge , Rico Rubio Ricardo , Couto Wörner Sergio , Grandío Noche Pablo
Published: October 2021

Designed with smooth and slender forms, Marineda footbridge in A Coruña (Spain) is a composite structure for pedestrians and cyclists that solves the access to one of the largest shopping centers in Spain, flying above a high-traffic highway.

The maximum deck height and the geometry in plan were established by the necessary vertical clearance over the highway and the situation of the starting and end points. In this way, and with the idea of avoiding structural elements over the deck to minimize visual impact, a three-span curved slender beam was designed. The main span is 85.8 meters long and comprises a composite airtight box-girder deck with variable depth from 1.75 meters near piers to 1.00 meter in midspan section. The two lateral spans, one on each side, are formed by a post-tensioned voided slab rigidly connected to pier and abutment, and with a strut element underground forming a rigid frame. In these spans the maximum deck height is 1.90 meters and the minimum is 1.00 meter. The deck width is 4.00 meters to accommodate both cyclists and pedestrians and has a transverse slope of 1.5% from the centerline to each side.

The curved geometry in plan, with a radius of 55 meters, and the stiffness of the lateral spans allow for an integral structure design without joints, that, along with the slenderness of the main span, give an unique appearance to the footbridge.
Mechanical Innovations Developed for the Lille Langebro Swing Bridge, Copenhagen
Authors: Thorogood Michael
Published: October 2021

The Lille Langebro (Little Langebro) pedestrian and cycle swing bridge opened to the public in August 2019. The bridge provides a quay-level crossing of the harbour for pedestrians and cyclists and was the outcome of an international design competition. In order to enable the passage of marine craft along the harbour the central sections of the bridge rotate. This paper gives a brief overview of the operating equipment associated with the movement of the two rotating spans before a more detailed discussion on the innovative moment connection developed to secure the joint between the two moving spans when in the bridge closed position.
Tintagel Footbridge

Published: October 2021

English Heritage published a design competition for a footbridge to offer a better accessibility to the Tintagel Castle. The new bridge links the mainland with the island, the real world to the imaginary world of legends. Its setting is extraordinary, remote. The context is therefore deeply reflected in the bridge design and construction. The bridge looks like and arch, but tells so much more after a closer look. It leaves a void, between present and history, reality and imagination.
The "Piccard Bridge" in Obergurgl, Austria
Authors: Brandstötter Rudolf
Published: October 2021

The new bridge in the rearmost Ötztal is not a touristic attraction, it is a simple necessity as the existing route over the glacier had become more and more dangerous and complicated to walk. The new bridge with a span of 137.20 m stays at a height of around 82 m over the glacier stream of the Gurgler Ferner. Since its construction in spring 2017, the bridge serves as a new connection between the Ramolhaus and the Langtalereckhütte. The remoteness of the construction site, rapidly changing weather conditions at 2500 m above sea level and the adversity in accessibility due to the valley slopes, which were up to 80° steep, brought along high demands for design and construction of the bridge.

Published: October 2021

This paper shows the methodology used for the dynamic identification and serviceability assessment carried out on a timber pedestrian walkway located in the Anillo Verde trail, upon the N‐102 road, between Zabalgana and Armentia, Vitoria, Spain. The footbridge is 61 meters long and 3 meters wide and consists of curved glulam structural beams, wood deck and steel cross bracings, designed by Media Madera Ingenieros Consultores. With applied research aims, an experimental campaign was carried out in December 2019, just after its erection process. Useful data was collected to estimate its modal properties and to calibrate the corresponding computational model. Also, some serviceability tests were carried out to quantify the vibrations induced by pedestrian crossing. Although there may be some other works with similar objectives and methodology, the peculiarity of this structure is the building material, its large size and the challenging one‐step erection process, resulting in a fully functional structural typology with attractive advantages from construction and environmental points of view.

Authors: Fidalgo Paulo , Almeida Rui , Caetano Elsa , Cunha Álvaro , Cachim Paulo
Published: October 2021

The current paper describes the structure and the dynamic behaviour of a footbridge built in Serralves Park at Porto, Portugal. The footbridge, named Tree Top Walk, is located in a slope in the park at the height of the top of the trees. Because it is in a slope, the footbridge develops with an irregular U-shape at a constant level. The total length of the footbridge is approximately 250 m. At its highest level, the height is 15 m.

Approximately at one third of the course there is a passage between the two branches of the U. At this zone, there is a staircase that allows to reach the footbridge at the middle of its course, from the woods and a small amphitheatre at a level of 14 m. The structure of the deck is made with timber while the columns are made with steel covered with timber across their height and the connection between the columns and the deck is performed with timber struts placed in the longitudinal and transversal directions. Three of the columns are made with a circular profile, while the others are 4-foot tubes connected at the top by a circular tube with

2.35 m length. The deck is made with four longitudinal girders with a cross section of 8x52 cm. Spans have different lengths, ranging from 5 to 14,34 m. In total there are 23 spans and 22 columns. In the structural analysis, dead loads, live loads, wind and earthquake actions were considered. To assess the dynamic behaviour of the structure, dynamic tests have been carried out.

Engaging the Public Through the Design of the Eastwick and Sweetwater Footbridge, London
Authors: Metters Edmund , Leung Kenneth
Published: October 2021

Bridge H16 is foot and cycle bridge located within the Queen Elizbeth’s Olympic Park, London. It aims to provide the user with an engaging experience as they cross between the Park to Hackney Wick and Fish Island. This has been achieved through close collaboration between the designer and architects during the early design development. This paper explores the history of the site, the key drivers that defined the bridge, the consideration for the user experience as they cross the bridge, material choices and detailing to successfully deliver the new pedestrian and cycle bridge. It is recognised that the value of the bridge is best expressed through the positive social and economic impact to the developing area. The footbridge was opened to the public during the Summer of 2019. The second bridge; a road bridge, is constructed and due
to open fully in the latter of 2021/early 2020.
Frequency-amplitude of Vibration of Modern Aesthetic Footbridges for Walking and Cycling
Authors: Sousa Oliveira Carlos , Luísa VIEIRA Ana
Published: October 2021

New urban developments are changing the traditional footbridges by contemplating (i) the new cyclic functionality of these structures, (ii) the wood and other light structural materials and, in many cases, (iii) the introduction of aesthetics. Previous studies were made on pedestrian footbridges composed by a simple supported beam with uniform distributed characteristics. The main objective of these past projects was to pass pedestrians across, safe and comfortably, with minimal cost of construction, without much aesthetics.

Nowadays, footbridges appeal to the best architects and engineering consortiums and each new one is viewed as entering in an aesthetic contest. The objective now is similar as referred before but, besides adding the cycling vehicles, they should look into aesthetics and to the environmental context. They span larger distances making use of more adequate materials. However, the dynamic characteristics might be a problem due to proximity of frequencies of the structure with the rhythm of the stepping of crossing. This is the objective of this paper to understand if more complex geometries and different materials pose problems. After looking into several cases in Portugal and Spain and, describing their main geometric and mechanical characteristics, the most important frequencies of vibration and amplitude of oscillation for various loadings were analyzed. Caution should be exercised to not excite resonance conditions. A case study of one of these structures is analysed in detail for deterministic conditions. Cycling is not a problem.
Short Span Modular Bridges of Guadua Angustifolia by Self-Construction, a Sustainable Alternative
Authors: Andrade Sofía , Lamus Fabián , Urazán Carlos
Published: October 2021

This paper presents the evaluation of an alternative for the construction of short bridges with Guadua
angustifolia Kunth as structural material. In the proposed model, the construction of bridges must be as easy
as possible, in order to be developed by the community in a short time, taking advantage of existing guadua
in the area. The bridges are composed by structural modules with a length of 5m, which can be precast
composed of two planar trusses which are connected using horizontal members that support the board and
give stability to the structure. The design was made considering that live loads will be applied inside the
structure, on the bottom chord of the trusses. Load values specified by the Colombian Bridges Code have
been used for the footbridge design.

AbstractÂ This study aimed Â to explore inference strategies necessary Â read journal Â article. Forty four English students Â read set of text onÂ  education text Â and Â answer Â comprehension question. Â The Â two main Â objectives Â in this study Â were to identify inference skills necessary to comprehend a research article in terms of the main ideas, the writing styl e/tone and other text-based elements such as lexical items, syntaxes well as discourse structures and to investigate inference strategies for copingÂ  with text. Twenty Â five of these participants also volunteered for an in depth Â interview. Â The findings Â revealed that studentsÂ  usually relied on their bottom up processing. They skipped difficult parts, especially technical information graphic Â illustration. TheyÂ  sought Â help from Â friends to enhance Â their understanding. Overall, Â they were successful at interpreting Â the thesis statement, the gist of section, Â the meaning Â of the tested words and Â clause.
