Authors: Huza Richard
Published: February 2021

The tremendous cost of deteriorating infrastructure as caused by the corrosive effects of chlorides in North America is well documented as being in the billions of dollars annually. Owners, planners, specifiers, operators and designers of reinforced concrete structures faced with solving the problem of deteriorating concrete caused by chloride attack of the steel rebar from chlorides are looking for long term, low cost solutions and to solve the heavy cost burden of premature replacement of structures, excessive repair and maintenance costs, traffic congestion and reduced utilization. This paper makes the case that the fundamental and unique properties and features of stainless steel reinforcement are the underpinnings of the vast body of indisputable evidence pointing to stainless steel reinforcement as being a significant positive contributor to extending the service life of existing structures and enhancing the durability of new structures exposed to chloride attack. The author offers his engineering and product/market development perspective as a stainless steel reinforcement industry insider providing details regarding the unique mechanical properties, the chemistry of this product and the benefits which can be leveraged, an overview of the important aspects of the ASTM standard for mill production, the evolvement of historic to the current types of stainless steel reinforcement most in use, a summary of various corrosion resistance test methods and research presenting the relative performance of various types of corrosion resistant reinforcement compared to stainless steel reinforcement, the cost effectiveness of the use of stainless steel reinforcement as represented by a life cycle costing analysis with commentary on pricing, the specification formats and best practices of primary users, a perspective on the applications of this product and the primary users in North America, a synopsis of the mill material supply situation, and finally an overview of the purpose and summary of the recently released ANSI / CRSI IPG4.1 document “Standard Practice for Stainless Steel Reinforcing Bar Fabrication Facilities”.
Engineering the Oculus – World Trade Center PATH Transportation Hub
Authors: Surtees Tom , Petschke Tobias , Viola Joseph M.
Published: February 2021

The Oculus structure is the centerpiece of the World Trade Center PATH Transportation Hub in downtown New York City. The main structure consists of two inclined steel arches supported by steel columns, which are anchored onto cantilevers embedded in the transit hall's concrete slabs below. A segmental erection method was proposed to erect the Oculus arches, which significantly reduced the amount of temporary shoring required and allowed construction to proceed at a faster pace. During erection, a detailed geometry control procedure was developed involving multiple survey targets to ensure erection proceeded on the correct path. Bolted connections were proposed in lieu of welding in many locations to accelerate erection. The methodology for bolting such large pieces of steel was developed and designed, then optimized to achieve further schedule improvements.‌
Innovative strengthening of steel truss nodes by Ultra-High Performance Concrete
Authors: Ivanov Stoyan , Geier Roman , Rebelo Carlos , Breda Ricardo
Published: February 2021

The paper presents one innovative idea for strengthening of steel truss nodes by UHPFRC. The nodes are totally encased in the UHPFRC with no additional conventional reinforcement. The connection between steel and UHPFRC is realized by epoxy resin only without any shear connectors. For proving the efficiency of this strengthening method five specimens are going to be tested in laboratory: one reference bare steel node, and four encased. The parameters that are going to be varied during the tests are the concrete cover and encasement length of the elements entering the node. The very promising results from the preliminary FEM of the nodes are presented herein as well as the description of the experiments envisaged.
Renovation of the Existing Lighthouse for New Radar System in the Gulf of Thailand
Authors: Buddee Samard
Published: February 2021

The new radar system mainly consists of a 5.7-meter-long SCANTER antenna, a 1.2-meter- diameter microwave dish and a 5.0-meter-high lightning protection rod, which are supported by a new steel structure located on the roof of the lighthouse. These additional loads are transferred directly to the existing interior columns under the roof. Ultrasonic Pulse Velocity (UPV) testing was conducted to investigate the strength and reliability of the existing lighthouse structures, and found that certain improvements to the existing structures had to be made. Ultimately, the structural engineer decided to strengthen these structures by covering them with glass fibre reinforcements in order to extend the lifespan of these structures for the new radar system.
Shaping Forces; the symbiotic relation between structure and architecture
Authors: Smits Joris
Published: February 2021

Over the past two decades architects are finding their way into the bridge design practice. Ever since the 90’s we have seen an exponential growth of the involvement of architects in bridge design. Many beautiful and well integrated designs have been realized all over the world, but an equal amount of farfetched bridge designs have seen the light of day.

What are the key design considerations to achieve a beautiful and yet structurally sound bridge? Does a structure always need to follow the most efficient form, according to the laws of mechanics and of finance? Or is there such a thing as symbiosis between Form and Force, a way of working that ensures that the final result becomes greater than the sum of its parts?

Best practices in bridge design from the authors architectural office demonstrate the belief that structure and architecture are involved in a symbiotic relationship. One cannot be successful without the other. Just how this successful interaction is achieved is the subject of this paper.
Long term deflections of Paudèze Bridges
Authors: Menétrey Francisco , Moreillon Lionel
Published: February 2021

The Paudèze bridges are two parallel bridges, each with a total length of around 400 m and a maximal span of 104 m. They were built using the balanced cantilever method between 1971 and 1974. After construction, a continuous increase in the deck deflections was observed. Since 1988, mid-span deck deflections of one of the two bridges are monitored using a hydrostatic levelling system. The continuous increase in deflections of the deck was measured from 14 years to 36 years of age of the bridge. In 2010, the deflections were reduced and stabilized by placing additional prestressing cables inside the box girder.

In preparation for the rehabilitation project planned for 2017, material properties were measured, crack patterns were recorded and the remaining prestressing forces were measured in some cables.

A detailed analysis was carried on the bridge which had been monitored using the finite element method. The purpose of this analysis is to understand the bridge behaviour so that the impact of the rehabilitation project can be analysed and optimized. Two different models were built: a viscoelastic beam model and a non-linear shell model using the fictitious crack model for concrete with a plasticity based formulation.

These finite element models and the comparison with the measured values allow the following conclusions. First, it is shown that the viscoelastic beam model and the non-linear shell model allowed approaching the instant deflections of the bridge. Second, it is shown that the non-linear shell model could reproduce the cracking pattern observed in the bottom slab of the box girder. Third, it is shown that the prestressing losses are higher than usually assumed. Finally, it is demonstrated that long-term deflections of the bridge deck could not be reproduced by the viscoelastic beam model. This is due to the available creep models according to which deflections and strains stabilize after 20 years. However, the measured deflections in the bridges continuously increased for 36 years. This clearly shows that the creep models given in codes are not adequate for predicting deflections of balanced cantilever bridges.
Grayston Pedestrian Bridge: A Shared Perspective of South Africa’s Connectivity and the Challenges of Getting There
Authors: Klassen Darryl , Ptak Jonah
Published: February 2021

The Grayston Pedestrian Bridge forms part of a pedestrian and cycling corridor recently built to connect residents of the Alexandra Township to the wealthy business district in nearby Sandton in the Gauteng Province of South Africa. Alexandra is one of the poorest urban areas in South Africa whilst Sandton is one of the Country’s most affluent. Previously separated by vehicle-centric infrastructure, the “Great Walk” project includes integrated bus rapid transit systems and provides unobstructed daily movement for the more than 10,000 people via a 6m wide sidewalk and bicycle lane with a 289m long cable-stayed pedestrian bridge over the busy M1 freeway at the Grayston Interchange. The project was envisaged as a community focused project incorporating sustainable best-practices such as local labour and design approaches intended to minimise future maintenance needs. While the project has achieved the original design goals, unforeseen challenges arose during the project’s tender and construction process. This required the project team to identify innovative solutions during construction without impacting the project’s bottom line. This paper intends to share the innovative ambitions from the challenges encountered on this important project for South Africa.

Published: February 2021

The Chacao Bridge is the first major bridge project in Chile, and when built it will be the largest suspension bridge in South America. The 2,750 m-long structure will connect the island of Chiloé with mainland Chile across the Chacao Channel. The three-tower suspension bridge will have main spans over 1 km in length each. The design faces many challenges related to the environment where the bridge is located; high seismicity, high wind, volcanos, tsunamis, sea waves, and potential erosion of the central island (Roca Remolinos) and the shores.

This paper presents the design and construction challenges for the project from the Owner’s perspective. Also, it discusses the interaction within the project team: owner (MOP), owner's engineer (RyQ and COWI NA) and the construction JV working together for successful delivery of this high profile project.
Samba e Polícia resistência e crônicas cotidianas de um olhar contra-hegemônico na cidade do Rio de Janeiro
Authors: Barbosa Eduardo
Published: February 2021

O objetivo deste trabalho é resgatar através de três sambas produzidos em épocas distintas, a violência policial como traço comum na linguagem do sambista, como um foco de resistência e contra-hegemonia frente ao Estado. Por meio da análise crítica do discurso sobre as três composições: Delegado Chico Palha (1938), Assim não Zambi (1979) e Numa cidade muito longe daqui - Polícia e Bandido (2009) percebe-se que o samba pode ser compreendido tanto como uma espécie de crônica do cotidiano carioca, como também um produto cultural e de resistência popular em relação ao poder coercitivo do Estado exercido pela polícia. Desse modo, busca-se comprovar que o samba é um material profícuo e um corpus legítimo para a análise dessa questão. Ao refletir sobre o papel da polícia na cidade do Rio de Janeiro, a violência policial aparece como traço em comum e fio norteador desses três sambas analisados para o artigo, pois ao invés de garantir a ordem pública e mediar os conflitos, a violência policial, conforme retrada pelos sambistas, acaba por causar graves transtornos.

ENVIRONMENTAL AWARENESS AMONG SENIOR SECONDARY LEVEL STUDENTS (MAHESHWAR AND MANDLESHWAR. DIST. KHARGON (M.P.)
Authors: Jain Ritesh
Published: February 2021

Environment is, in general terms, a surrounding or condition influencing development and growth of all the living beings.

For the last several decades nature and environment have always been a source of human reflection and investigation as the environmental pollution has reached to such a critical stage that we find ourselves passing through an irreversible climate change and are not able to retrieve the previous climate back.

Now the liability lies on the next generation and I am sure that environmental awareness among the senior secondary students will lead the next generation towards restraining the unstoppable environmental changes.

It can be said that environmental education is education through environment, about environment and for environment. It is both a style and subject – matter of education. In so far as the style is concerned, it means teaching for environment that include components and issues such as controlling the environment, establishing proper ecological equilibrium which entails proper use and conservation of resources and also involves control of environment is not only functionally useful but is also aesthetically enjoyable.

Rheological modeling of pasta dough flow processes in channels of convergent-divergent inserts of molding matrix
Authors: Grudanov V. Ya. , Torgan A. B. , Barsukov V. G.
Published: February 2021

One of efficient directions for pasta press designs modernization is installation of special conical-and-cylindrical inserts in the matrix wells in front of the dies having, like Venturi tubes, narrowing zones (convergent), expansion (divergent) and a cylindrical path located between them. However, rheological aspects of such method of forming tool modernizing in relation to pasta presses have not been studied, recommendations for structural elements calculation and design have not been developed. All this is a significant obstacle for using the method in engineering and industrial practice. The research purpose is to develop rheological models the pasta dough flow in the conical-cylindrical channels of convergent-divergent inserts and to evaluate with their help the impact of structural dimensions and rheological properties on resistance to pasta dough flow. Pasta dough was considered as a rheological complex nonlinearly viscous plastic material. In technical calculations contribution of shear strength was neglected and a rheological analysis was performed using the Oswald-de-Vila power law equation. Analytical dependences obtained make it possible to calculate the pressure drops in the convergent-divergent insert and its elements. Numerical modeling was performed and calculated data were obtained regarding the impact of dimensions of structural elements of the insert and rheological parameters of pasta dough on its resistance to viscous flow. The results obtained can form the basis of engineering and technological calculations in design of convergent-divergent inserts for laboratory and industrial matrices of pasta presses.

Design and manufacture of air quality measurements based on arduino ATmega 2560 using dust ZH03A laser sensor
Authors: Wibawa I Made Satriya , Putra I Ketut
Published: February 2021

This study aims to design an air quality measuring instrument that is more efficient, relatively cheaper and can be carried because it has a smaller shape and size compared to the existing tools in the Meteorology, Climatology and Geophysics Agency (BMKG). The main processor uses the Arduino ATmega 2560 microcontroller. This microcontroller functions as a processor for PM2.5 and PM10 concentrations which are the output of the ZH03A sensor. The design results are calibrated with a standard tool, namely BAM1020 which is owned by the BMKG air quality sector to measure air quality. The calibration results obtained that the average value issued by the reference tool which is used as a standard compared to the ZH03A sensor in the design results for PM 2.5 is 6.5 µm / m3, and for the average value of PM1.0 is 2.8 µm / m3 the calculated Air Pollution Standard Index (ISPU) value is 126 µm / m3 including the medium category according to the Air Pollution Standard Index.
Burning Witches: The Moral Dilemmas of Ashaninka Leaders
Authors: Delgado Guillermo Enrique , Frisancho Susana
Published: February 2021

This paper focuses on the moral reasoning of Ashaninka leaders about the burning of witches, a cultural practice that has received scant attention from intercultural scholars. We first contextualize burning witches as a cultural practice of the Ashaninka people. Then, based on qualitative interviews, we present the experience of six Ashaninka leaders with witchcraft and witchcraft accusations, as well as their moral reasoning about the social mechanisms that the Ashaninka people have traditionally used to control evil sorcery. The participants are three men and three women from the Ucayali and Junín regions in Peru’s Amazon basin. Finally, we discuss intercultural moral education and the need to analyze the reasons behind cultural practices in order to understand the rationality and reasonableness of others.
A "Universal": fenômeno mercadológico x fenômeno religioso
Authors: Valle João Edênio dos Reis
Published: February 2021

O artigo analisa o caso ma is espetacular de êxito mercadológico entre as igrejas neopentecostais da atualidade. A “Igreja Universal do Reino” logrou traduzir em termos de terceiro mundo latino-americano a “teologia da prosperidade” e as práticas de marketing do evangelismo norte-americano. O artigo considera e põe em confronto duas dimensões do sucesso da “Universal”: a mercadológica e a religiosa. Sem absolutizações, dá a ambas igual importância na explicação psicossocial do êxito missionário desta Igreja, fundada no Brasil há 20 anos e hoje presente em mais de 40 países, em quatro continentes. Na parte final, sempre desde um enfoque psicossocial, o artigo faz um balanço pastoral crítico, buscando enunciar as linhas pastorais que poderiam servir como pistas de resposta teológico-pastoral das demais Igrejas cristãs, tanto da católica quanto das demais denominações históricas, desafiadas pelo fenômeno neopentecostal.

Lizardite rich peridotite has never been used to prepare ceramic specimens, especially in Morocco. For this raison, potential use of naturally abundant lazirditic material from the Rif domain, as a supply for ceramic industry, has been evaluated. The effects of lizardite addition to magnesite and dolomite mixtures on the thermomechanical properties of the calcined ceramics were also detailed. To achieve this target, natural lizardite, magnesite and dolomite samples were collected in ultrabasic Beni Bousra massif. Those raw samples were used for the synthesis of a forsterite-monticellite rich ceramics. Both raw and sintered samples were characterized by x-ray diffraction, scanning electron microscope and fourier transform infrared. The obtained results showed that both magnesite and dolomite were mainly composed of MgCO3 and CaCO3. In contrast, lizardite sample showed high amounts of SiO2, MgO and Fe2O3. An increased amount of lizardite in the initial mixtures enhanced mechanical and dimensional properties of the prepared ceramic specimens, and subsequently, the production of ceramics with the required technological properties. Thus, the preparation of Moroccan lizardite-based ceramics is technically feasible, economically justifiable and socially desirable due to the contribution to the economic growth of the raw materials sector, especially ceramic industry.
Elasto-plastic Analysis of High-strength Concrete Shear Wall with Boundary Columns Using Fiber Model
Authors: Tong Xiaolong , Chen Fumin , Ou Yangjing , Xiao Sixi , Wu Jianliang
Published: February 2021

In this study, an experimental study and numerical calculations using fiber model were conducted for four high-strength concrete shear walls with boundary columns under low cyclic load. The boundary column and shear wall were divided into fiber elements, and PERFORM-3D finite element analysis software was used to carry out push-over analysis on the test specimens. The results show that the finite element analysis results were in good agreement with the experimental results. The proposed analysis method could perform elasto-plastic analysis on the high-strength concrete shear wall with boundary columns without distinguishing the categories of frame column and shear wall. The seismic performance of high-strength concrete shear wall with boundary columns was analyzed using the following parameters: axis compression ratio, height to width ratio, ratio of vertical reinforcement, and ratio of longitudinal reinforcement in the boundary column. The results show that the increase in the axial compression ratio causes the bearing capacity of the shear wall to increase at first and then to decrease and causes the ductility to decrease. The increase in the height to width ratio causes the bearing capacity of the shear wall to decrease and its ductility to increase. The ratio of vertical reinforcement was found to have little effect on the bearing capacity and ductility. The increase in the ratio of longitudinal reinforcement in boundary column resulted in a significant increase in the bearing capacity and caused the ductility to decrease at first and then to slowly increase.

This research, entitled legal aspect for teachers in educating their students to avoid criminalization, aims to find out and analyze how to resolve and prevent disputes for teachers and students so that teachers' actions to students and students to teachers will not be easily criminalized. This is normative legal research that will explore the contents of statutory regulations. Based on the study results, the education system in schools no longer emphasizes academic achievement on paper anymore. Developing and improving students' morality and mentality in social interactions is one crucial element that must be done. One alternative that can be used as a reference for teachers' actions towards their students, mainly the reasons teachers do such acts, is that all Teachers substitute parents in the school.Keywords: Students, Teachers, Criminalization.

Effect Effect of Black Rice Bran on the Pharmacokinetics Profile of Glibenclamide in Hyperglycemic Rats
Authors: Wahyuni Arifah Sri
Published: February 2021

Black rice bran (BBH) which contains anthocyanins has the ability to lower blood sugar. In therapy diabetes mellitus (DM) it is possible that BBH is used together with the oral antidiabetic Glibenclamide (Gli). Glibenclamide, a weak acid, is well absorbed in the gastrointestinal tract. The absorption of BBH is also good under acidic conditions. So, it is necessary to study the pharmacokinetic interactions between Gli and BBH.

The study was designed using a one-way completely randomized design of ten (10) hyperglycemic rats, divided into two groups. Group I rats received Gli 5 mg / kgBW treatment, and group II received Gli 5 mg/kgBW along with BBH 50 mg / kgBW. Sampling was carried out at 1, 2, 4,6, 8 and 24 hours after treatment. Gli levels in the blood were determined by Liquid Chromatography/Mass Spectroscopy (LC/MS).

The results showed that in the absorption phase, giving BBH with Gli did not affect the Gli profile in terms of parameters Tmax, Cmax and AUC0-inf. Likewise, in the distribution and elimination phases in terms of parameters VD, ClT and elimination half-time (t1/2). So that the provision of BBH does not affect the pharmacokinetic parameters of Gli in hyperglycemic rats.

Os sistemas wetlands construídos são uma ecotecnologia de tratamento de águas residuárias enquadrados como soluções baseadas na natureza. Inúmeros elementos físicos e biológicos – em destaque os materiais filtrantes, as macrófitas e os microrganismos – atuam em consonância nas remoções da matéria orgânica suspensa e dissolvida presentes nos afluentes submetidos ao tratamento, bem como, nas transformações dos nutrientes presentes. Os wetlands construídos compõem inúmeros arranjos tecnológicos de tratamento de esgotos, são consolidados no mundo e no Brasil como mais uma opção para o controle da poluição hídrica. Inúmeras empresas, operadoras de saneamento, universidades e centros de pesquisa vêm aplicando e estudando as diversas modalidades de wetlands construídos. O Grupo Wetlands Brasil, o qual congrega inúmeros pesquisadores e praticantes distribuídos em todo o território nacional, foi estabelecido há uma década tendo como premissa a disseminação da utilização desta ecotecnologia na busca da universalização do esgotamento sanitário.
(Des)pregamentos e táticas nos cotidianos narrados por travestis: Desalojamentos em espaços prisionais como modos de (r)existências
Authors: Casteleira Rodrigo Pedro
Published: February 2021

This book aims to analyze four crossdressers narratives who have been imprisoned for different periods of time in order to raise debates on resistance ways carried out by each one of them. The crossdressers interviewed here were reached by different connections such as friends in common, social media or phone calls, which did not represent a closed and narrowed field but one that it is open and flexible. The issues raised here tried to sketch the crossdresser category through the words by crossdressers writers along with the concepts about themselves and self- determinations, therefore shaping a kind of autobiography even if it is led by a semi- structured script. The existing connections among them, beyond the crossdresser category, lie at first in their access to the prison system and later in finding ways to make it possible to go through life imprisonment. These articulated methods are tactics thought in the space and time web, that is, on a daily basis. This is also one of the book investigation focuses, once it matters to understand not the crossdressers heroic actions, but the ordinary ones, the usual ones, articulated according to educational backgrounds thought as being a less important education.
Consciência política e humanização do parto a luta pelo direito à formação de obstetrizes na Universidade de São Paulo

In today's globalized world, violence is structural and connected to the still unmet demands of society. Brazil has one of the highest violence rates, aided by the chronic socio-economic inequality which our political model insists on reproducing and deepening. Violence against women has pride of place in this picture. In the Europe of XVIII century, women's vocation for motherhood was praised, aligned with philosophical values and discourses of the time, giving rise to unconditional love as a true myth founder of the ideology in the bourgeois economy of early capitalism. The idea of a paradigmatic body is anchored in a dualism that is both physiological and anatomic and in which ethical, moral, psychological and socio-cultural aspects will unveil. The transition from home childbirth to hospital childbirth initiates the phase of maternity and childhood protective public policies. A consequence, however, was shutting out feminine participation, preventing its main role in childbirth and resulting in us boasting one of the highest indexes of unnecessary C-sections in the world. The modern woman has gained a lot in autonomy. She has freed herself from moral, social and legal ties, nevertheless she is and always will be the owner of the biological body that is capable of generating a new life and guarantee the preservation of human species. The humanization of birth and the health of mother and child is pressing in the country, along with international reference organizations in this area, as the author of the present work defends and proves.

Investigations of laminar fluid flow between two moving or stationary plates, and two rotating discs, over the years were geared toward how to increase Tesla-based turbine efficiency. Therefore, this research entails the construction, design and simulation of a Tesla turbine in order to investigate the potential of Tesla turbine for energy generation. Method of solution entails the design and construction of a physical model Tesla turbine from locally sourced materials. The physical model geometry and design parameters were then used to conduct numerical simulation. Performance evaluation was then carried on the physical model and the simulation model. The result showed that voltage, current and power all increase with increase in rev. per minute.  The result obtained indicates that for higher power generation, a Tesla turbine design with higher revolution per minute capability will be required.  Turbine model simulation showed that radial velocity vector to be concentrated at the discs periphery and outlet.

The research results are good references for design of larger Tesla turbine for community use.
