Testing recycled concrete aggregate suffering different levels of alkali-silica reaction for use in new structures
Authors: Piersanti Matthew
Published: June 2021

As concrete reaches the end of its service life, it is demolished and placed in landfills, which is not sustainable as this consumes land space. Many demolished structures are crushed into recycled concrete aggregate (RCA) and used in new construction work to reduce concrete waste. To be used in concrete, the effects of RCA on the new structures should be carefully examined. The RCA studied in this research is an alkali-silica reactive gravel from Sudbury, Ontario. The RCA was obtained from different elements of a 20-year old bridge that suffered different levels of deterioration. It was determined that the level of deterioration that affected the previous structure does not significantly affect the expansion that will occur in the new structure. It was also determined that the expansion could be mitigated through the use of supplementary cementing materials although higher levels are required compared those required for the virgin aggregate.
Behavior of normal strength concrete slabs under static and dynamic loads
Authors: Jeddawi Turky Sami
Published: June 2021

An experimental investigation has been conducted to determine the deformation and failure characteristic of slab under static and dynamic loads. Two identical reinforced concrete (RC) of dimensions 1950 x 1950 x 100 mm are tested under same boundary conditions. All top and bottom reinforcement are 10 M doubly plates reinforcement with total 1.0 % steel ratio. The static load is applied at the midpoint of the slab by using load cell 400 x 400 mm with a capacity of 250 kN. The static load increment used in this investigation is 5 kN. The dynamic load is applied at the midpoint of the slab by using a drop-weight of 475 kg from a height of 4.15 m generating an impact energy of 19.24 kJ with impact velocity of 9 m/s. The experimental results revealed that the absorption energy of the impact loading is about 1.4 times the static loading. The maximum deflection is found to be slightly higher for impact loading.
Assessing pavement conditions and their effect on road safety: Ontario experience
Authors: Nemtsov Iliya
Published: June 2021

The increasing need to rebuild and repair Ontario highways has motivated this research aimed at maximizing the efficiency of pavement maintenance and design. The first of two complementary objectives were to evaluate the safety improvements of reduced pavement roughness on two-lane undivided Ontario highways using the Empirical Bayes and Cross-Sectional analysis methods. The second objective was to improve the prediction of pavement distress and surface roughness by examining the impact of local calibration of prediction models. The findings suggest that better pavement conditions can reduce the severity of fatal and injury collisions by as much as 12% in some cases and therefore that pavement maintenance decisions should incorporate road safety when assessing cost-life analysis. The results provide a basis for those decisions in that they can be used to estimate the safety effect of a specific improvement in roughness.
Nonlinear dynamic response of seismically excited rectangular concrete liquid filled tanks
Authors: Farzin Arash
Published: June 2021

The effect of nonlinearity on behaviour of rectangular concrete tanks partially filled with water is studied. The nonlinearity in the numerical modeling of the surface liquid sloshing performance and hydrodynamic pressure initiates from unknown boundary conditions of contained liquid volume. The nonlinear simulations are performed for Time-History seismic analysis using the finite element software ABAQUS/CAE. The nonlinear results are compared with linear analytical solutions and ACI 350.3-06 code. A Paramedic study is conducted to investigate the effect of tank plan dimension, frequency content of different seismic ground motions, nature of earthquake movements, and interaction of bi-directional component of earthquake on the maximum sloshing height of liquid. The results reveal that the nonlinearity is more significant in shallow tanks. Moreover, nonlinear hydrodynamic pressure distribution has no important difference with linear calculated pressure except for the surface sloshing pressure acting on the top of tanks. The linear ratio of depth of liquid to tank plan dimension used in ACI 350.3-06 formulation is found to be less accurate for calculating the maximum sloshing height of liquid.
Effect Of The Horizontal Component Of Earthquake On The Buckling Of Concrete Spherical Shells
Authors: Madueño Nathalie Elena Moreno
Published: June 2021

The buckling failure of reinforced concrete spherical shell structures under the effect of the horizontal component of earthquake is investigated using a finite element method over a wide range of shell configurations. For this effect, two different loading case scenarios are considered; first, the shell is analyzed under the effects of the vertical seismic component alone. Then, the model is reanalyzed under the same loading conditions plus the horizontal earthquake component, taking into account two different horizontal-to-vertical earthquake spectral ratios. It is concluded that including the horizontal component of earthquake can result in a reduction in the buckling capacity of this type of structure; the impact of which is highly influenced by the horizontal-to-vertical earthquake spectral ratio and the shell geometry. It is also observed that the formulation adopted by ACI slightly overestimates the buckling capacity of spherical shells especially when horizontal seismic effects are included.
Impacts of autonomous vehicles on traffic volume: scenarios based on survey data for the City of Karlsruhe
Authors: Dörflinger Philipp
Published: June 2021

Autonomous vehicles will become a significant influence in the field of traffic and transportation. To determine the possible impact of fully automated traffic, this thesis analyzes trip-pattern data for the City of Karlsruhe, Germany. Based on survey data from the year 2012, the traveled distances are calculated in Karlsruhea baseline scenario as well as two competitive scenarios: best-case and worst-case. The database is analyzed for the most emerging trip patterns in three areas of the City of Karlsruhe. Trip data, including trip distance and mode choice, are analyzed by trip purpose and individual groups (based on employment status). By modifying the average trip distance, mode choice and trip patterns based on literature reviewed information, the consequences of autonomous vehicles are estimated. The study shows, that autonomous vehicles have the potential to reduce traffic (best-case), but on the other hand, could approximately double the overall traveled vehicle distances (worst-case).
Membrane structures - an introduction and manual for the design process of membrane structures
Authors: Hörth Niclas
Published: June 2021

Membrane structures are are an unfrequently used architectural design element in the modern society due to their simplicity and elegance. However, these structures require often in their design process the usage of complicated numerical finite element softwares because of their non-linear behavior. Written calculations can only be used for the preliminary determination of the required pretensioning, but not for the whole design process, which includes several different loading cases. Therefore, this work with the title Membrane Structures - An Introduction and
Manual for the Design-Process of Membrane Structures intends to develop a possible way of determining stresses in a membrane structure caused by additional loadings.

Performing and preserving memories: vernacular photographs in the South Vietnamese diaspora
Authors: Huỳnh Julia Trúc Hạ
Published: June 2021

This thesis explores how photographs from 1980-1995 of the South Vietnamese diasporic community in Orange County, California communicate selective ideas about exilic identity and memory following the militarized migration of this refugee community fleeing war. Focusing on two case studies drawn from photographs included in the Paul Tran Files and the Project Ngọc Records, the thesis investigates the (in)visible desires of the community and how such desires are (re)produced and mediated through images. Vernacular photographs of commemorative events produced by the community are crucial to our understanding of the visual tropes used to anchor the Vietnamese diasporic identity. Additionally, the photographs themselves function as a means of contesting nation building and for intergenerational transmission of memory. Just as importantly, an examination of the photographs’ multi-temporal and serial qualities reveals how youth are culturally disciplined through the gendered labour of memory keeping.

Intracanopy Lighting in Phytocenoses and Photobiological Efficiency of Radiation in Photoculture Conditions
Authors: Tikhomirov Alexander A.
Published: June 2021

The review is devoted to the study of the internal radiation regime in the canopies cultivated under controlled environmental conditions. The expediency of using canopies as an object of research for evaluating the photobiological efficiency of radiation in light culture conditions is justified. The appropriateness of light measurements in multi-tiered canopies is shown, taking into account the role of leaves of different tiers in the formation of an economically useful crop. The main requirements for light devices for their use in measuring artificial radiation in light culture conditions are considered, and a brief analysis of the existing instrument base for performing these studies is given. A number of examples show the complexity and ambiguity of the internal structure of the light field that is forming within canopies in light culture conditions. Conceptual approaches to the choice of spectral and energy characteristics of artificial irradiation for plant light culture are proposed and justified. The necessity of taking into account the light conditions of leaves of different tiers when choosing the spectral and energy characteristics of light sources for the cultivation of multi-tiered canopies is justified. Techniques, methods, and light sources used for additional intracanopy lighting are analysed. The efficiency of using side illumination of plant canopies and conditions for its implementation are considered. The advantages of the volume distribution of canopies on the most common multi-tiered lighting installations are discussed. Based on the presented material, we consider ways to improve methodological approaches for evaluating the photobiological effectiveness of artificial radiation in light culture conditions for canopies of cultivated plants, taking into account the features of their architectonics and internal radiation regime.
APPROACH TO DETERMINATION OF SIZES OF THE FORECASTING HORIZON FOR TREND MOD
Authors:   The National academy of the National Guard of Ukraine, Batsamut V.
Published: June 2021

The article substantiates an approach to determining the size of the forecasting horizon for making forecasts using trend models. In contrast to the known approaches, the proposed approach takes into account the rate of development of the process under study and the variance of accumulated estimates and is based on controlling the stay of the predictive estimate within a certain interval. The sizes of the interval are determined by the selected quantile of the standard deviation of the values of the random variable. The author substantiated a set of calculated expressions to obtain estimates of the permissible forecasting horizon for trend models. The approach proposed in the article does not apply to constant functions, since they do not reflect the rate of change of processes. It is proposed to carry out the reliability of forecast estimates obtained on the calculated forecasting horizon according to the classical scheme - through the size of the confidence interval calculated for a certain level of significance, which is chosen by the decision-maker. For this purpose, the article provides expressions for calculating the standard mean square error for a linear function, as well as polynomials of the 2nd and 3rd orders. The approach developed in the article is proposed to be used in the practical activities of the management bodies of law enforcement formations during the forecasting of trends in the development of the operational situation in the field of public order protection, as well as ensuring public safety in the country's region.

The article discusses approaches to ensuring the required level of reliability of radio electronic means when designing the design of products, taking into account the metrological and diagnostic support during their operation. It is known that up to 80% of the current repair time is occupied by the search for defects, therefore, special attention is paid to the influence of the product design on minimizing the average diagnosis time. The quantity of elements of modern radio electronic means is constantly increasing due to the expansion of their functions and automation of technological operations, but the requirements for their reliability remain constant. This contradiction can be solved by increasing the reliability of the element base, which leads to an increase in the cost of the product, which is not always acceptable. Therefore, there is a problem of providing the necessary values of reliability in other ways, including taking into account the requirements of maintainability of products in the design, as well as improving metrological and diagnostic maintenance during operation in real conditions using modern advances in metrology and technical diagnostics. Thus, there is a problem of quantitative assessment of the impact of the design of radio electronic means on their reliability, as well as a reasonable choice of recovery options for maintenance in the minimum time. This will provide the required values of reliability without additional costs during the operation of radio electronic means. Possible options for restoring the operability of multi-output objects, which include power supply subsystems, are considered. It is shown that a reasonable choice of design, metrological and diagnostic support reduces the time of current repair by up to 30%. The use of the results obtained in the design of promising and existing radioelectronic devices for various purposes makes it possible to increase the efficiency of current repairs in real conditions.

As fraturas orbitárias transcorrem com considerável frequência e quando há o envolvimento das suas paredes, geralmente observam-se mudanças no volume orbitário, que resultam em diversas alterações clínicas. Objetiva-se por meio desse estudo, correlacionar o aumento do volume orbitário, pós-trauma em face, com as alterações clínicas observadas, enfatizando a influência dessas variáveis na tomada de decisão sobre a intervenção terapêutica mais adequada. Realizou-se um levantamento bibliográfico nas principais bases de dados online, por meio dos descritores: Órbita, Fraturas Ósseas, Tomografia e Cirurgia Maxilofacial, contemplando artigos completos de pesquisa, revisão, e ainda, relatos de caso, publicados nos últimos 5 anos (2015-2020), nos idiomas inglês, português e espanhol. Por meio do estudo, tornou-se claro que as fraturas orbitais representam 40% de todas as fraturas faciais, podendo esse  percentual aumentar quando há o envolvimento de outros ossos articulados. Evidenciou-se a existência de uma correlação positiva entre o aumento de volume orbitário e a ocorrência de algumas alterações clínicas. Com relação a escolha do tratamento apropriado para a correção das deformidades, compreendeu-se que características clínicas e radiográficas devem ser observadas, sendo a diplopia, distopia, enoftalmia, exolftalmia, oftalmoplegia e lesão nervosa as principais alterações clínicas. Dessa maneira, conclui-se que o aumento volumétrico influencia diretamente as repercussões clínicas pós-traumas em face, devendo ser considerado no processo decisões terapêuticas, que podem ser cirúrgicas ou conservadoras.

O experimento foi conduzido entre outubro de 2019 e março de 2020, a pleno sol no viveiro de mudas do Laboratório de Ecologia Vegetal, localizado no Departamento de Fitotecnia e Ciências Ambientais do Centro de Ciências Agrárias, da Universidade Federal da Paraíba. O delineamento utilizado foi em blocos completamente casualizados, com seis tratamentos e três repetições, com 28 plantas por parcela. Utilizou-se as cultivares: Bourbon; Catuaí Vermelho 144; Catuai Amarelo 62; Mundo Novo; Catucai 24/137 e Arara. Avaliou-se a porcentagem de emergência das plântulas, altura de planta, diâmetro do colo e número de pares de folhas. Todas as cultivares são promissoras para a região, exceto a cultivar Arara que apresenta inferioridade em todas as variáveis e porcentagem de emergência de plântulas 36,6% menor que as demais. As cultivares Bourbon e Mundo Novo apresentaram melhor adaptação e um crescimento superior às demais cultivares na altura média de plantas aos 180 dias após a semeadura, o que pode indicar maior adaptação às condições ambientais, como a amplitude térmica e insolação. No geral, estes resultados auxiliam na tomada de decisão para a escolha de cultivares a serem produzidas nas condições de cultivo do Brejo da Paraíba e norteia para trabalhos de pesquisas futuros.

Foi realizada uma busca nas bases da Biblioteca Virtual de Saúde (BVS) que inclui LILACS, MEDLINE, MEDCARIB, OPAS/OMS, PAHO e WHOLIS; PubMed; EBSCO; SciELO e Scopus no período entre janeiro de 2010 a dezembro de 2020. Para a busca utilizou-se a combinação dos seguintes termos: “Cirurgia Bariátrica” OR “Bariatric Surgery’’ AND “Comportamento Alimentar” OR “Feeding Behavior”. Foram incluídos estudos originais, desfecho principal as alterações comportamentais após cirurgia bariátrica em pacientes obesos, escritos nos idiomas português e inglês. A analise final foi composta por 13 artigos. Desses, 84,6% foram realizados nos últimos 5 anos, 61,5% dos estudos utilizaram os delineamentos longitudinais, predominou pacientes obesos com o Índice de Massa Corporal (IMC) ≥ 35 kg/m2, faixa etária de 31 a 52 anos e a maioria dos estudos foram realizados no Brasil 30,7%, Israel 15,4% e Reino Unido (15,4%). As alterações no comportamento alimentar após cirurgia bariátrica foram um aumento de comedores de lanches e de doces, intolerância alimentar e palatabilidade alterada, dificuldade de ingerir alimentos proteicos e gordurosos. No comportamento emocional houve alteração do humor, aumento e/ou redução de sintomas depressivos e de ansiedade, e aumento da impulsividade. Em conclusão, após cirurgia bariátrica os pacientes obesos apresentam alterações de comportamento alimentar e emocional.

The school profile is one of the most important things in promoting a school. By displaying a school profile, visitors from a school can see all teaching and learning activities in a school. This is very important considering the school profile is also a promotional medium that can be displayed to others. In developing this school profile, the author is interested in making it use a website using analysis methods and object-oriented design. One of the objects chosen is SMK Istiqlal Palembang, which so far has no school profile using the website, so it is hoped that it can become a promotional media for prospective students who want to enter this school. The programming language used is PHP and the database used is My SQL.

Some research that has been carried out in patients who have already undergone COVID-19, indicate that between 20%-30% of these will suffer intense hair loss, multiplied by 4 or 5 after 2 to 4 months later of the illness. This exaggerated hair loss is known as telogenic effluvium. In telogenic effluvium, it is produced by an alteration in the hair growth cycle that generates an alarming loss for a limited period of time. As in any infection or period of stress, the root of the hair weakens and months after having overcome it, the hair falls in an abnormal and exaggerated way. The objective of presenting this case is to describe one of the most important and rare dermatological manifestations, which has been derived from SARS-CoV-2 infection. We present the case of a 41-year-old female patient, who was admitted to the emergency department after presenting a clinical picture of 8 days of evolution consisting of dry cough, tachycardia and diaphoresis, for which the antigen test for SARS-CoV-2, revealing a positive result, so it was decided to enter for medical management.

Glycyrrhetinic acid (GA) is a principal bioactive pentacyclic triterpenoid from Glycyrrhiza uralensis. Uridine diphosphate-dependent glycosyltransferases (UGTs) have been widely used to catalyze glycosylation of diverse nature products for the development of potential therapeutic compounds. In this study, we have characterized a UGT109A3 from Bacillus subtilis, which can glycosylate both the free C3 hydroxyl and C30 carboxyl groups of GA to yield a unique 3, 30-O-β-D-diglucoside-GA. By coupling the microbial UGT109A3 to plant sucrose synthase (SUS), GA-diglucoside could be biosynthesized in an efficient and economical way. With a fed-batch glycosylation, a large scale of GA-diglucoside (6.26 mM, 4.98 g/L in 8 h) could be enzymatically transformed from GA. The obtained GA-diglucoside showed a significant water solubility improvement of around 3.4 × 103 fold compared with that of the parent GA (29 μM). Moreover, it also exhibited dose-dependent cytotoxicity toward human colon carcinoma Caco-2 cell line according to MTT assay, having an IC50 at 160 μM. This study not only establishes efficient platform for producing GA-glucosides, but is also valuable for developing further the biosynthesis of other complex glycosylated natural products.

Death of cardiac fibroblasts (CFs) by ischemia/reperfusion (I/R) has major implications for cardiac wound healing. In in vivo models of myocardial infarction, toll-like receptor 4 (TLR4) activation has been reported as a cardioprotector; however, it remains unknown whether TLR4 activation can prevent CF death triggered by simulated I/R (sI/R). In this study, we analyzed TLR4 activation in neonate CFs exposed to an in vitro model of sI/R and explored the participation of the pro-survival kinases Akt and ERK1/2. Simulated ischemia was performed in a free oxygen chamber in an ischemic medium, whereas reperfusion was carried out in normal culture conditions. Cell viability was analyzed by trypan blue exclusion and the MTT assay. Necrotic and apoptotic cell populations were evaluated by flow cytometry. Protein levels of phosphorylated forms of Akt and ERK1/2 were analyzed by Western blot. We showed that sI/R triggers CF death by necrosis and apoptosis. In CFs exposed only to simulated ischemia or only to sI/R, blockade of the TLR4 with TAK-242 further reduced cell viability and the activation of Akt and ERK1/2. Preconditioning with lipopolysaccharide (LPS) or treatment with LPS in ischemia or reperfusion was not protective. However, LPS incubation during both ischemia and reperfusion periods prevented CF viability loss induced by sI/R. Furthermore, LPS treatment reduced the sub-G1 population, but not necrosis of CFs exposed to sI/R. On the other hand, the protective effects exhibited by LPS were abolished when TLR4 was blocked and Akt and ERK1/2 were inhibited. In conclusion, our results suggest that TLR4 activation protects CFs from apoptosis induced by sI/R through the activation of Akt and ERK1/2 signaling pathways.
