Corrosion evaluation of steel bars in steam-cured concrete under chloride attack and alkali–silica reaction
Authors: Wang Ni , Sugiyama Takafumi
Published: August 2022

One of the challenges to reinforced concrete slabs in bridges is deterioration due to rebar corrosion by deicing salts. In order to simulate a concrete slab subjected to deicing salt penetration from the top surface of the bridge slab during winter, high-strength steam-cured concrete with double-layer reinforcements was exposed to 10% sodium chloride solution to investigate rebar corrosion. Five concrete mix proportions were prepared, including high early strength concrete and concrete containing fly ash and blast furnace slag as supplementary cementitious materials (SCMs). For both the high early strength and fly ash concretes, alkali active andesite in the pessimum proportion was mixed with coarse aggregates to investigate the effect of alkali–silica reaction (ASR) on rebar corrosion. It was found that the combined effects of chloride attack and ASR adversely affected the corrosion resistance of high early strength concrete. Fly ash concrete had excellent performance as to corrosion resistance and ASR mitigation. Results also showed that a widely used electrochemical technique known as the half-cell potential test can satisfactorily diagnose corrosion of double-layer reinforced concrete. Concrete specimens containing SCMs with no ASR threat showed no signs of steel bar corrosion and significantly low chloride diffusion coefficients after 3 years.

Published: August 2022

Background: The shoulder joint tuberculosis (TB) is a rare disease. The shoulder joint is involved in 1–10.5% of the population with skeletal tuberculosis. The diagnosis of disease at an early stage is difficult, delaying the treatment and leading to poor quality of life. Case summary: A 48-year-old female with shoulder joint debridement in a case of right shoulder joint tuberculosis presented with complaints of pain, weakness, and functional immobility of the right shoulder. Physiotherapy rehabilitation was given to her three days a week for the period of four months, including electrotherapeutic modality, electrical stimulation, therapeutic exercises, and upper body ergometer training. Range of motion (ROM), muscle strength, and shoulder pain and disability index (SPADI) were used as outcome measures .As a result of physiotherapy rehabilitation, patient was able to achieve an optimal functional range of motion of flexion (from 10⁰ to 100⁰), abduction (from 20⁰ to 85⁰), extension (from 5⁰ to 15⁰), internal rotation (from 28⁰ to 35⁰) and external rotation (from 35⁰ to 40⁰), overall improvement in shoulder joint muscles strength from grade 2 to 3, and reduction in shoulder pain and disability index from 86% to 41% despite having marked bony destruction. Conclusion: Physiotherapy rehabilitation strategies were found to be effective for improving shoulder joint function after joint debridement in the case of shoulder joint tuberculosis. The patient achieved a functional state sooner than the patients documented in currently available literature for this diagnosis. KEY WORDS: Tuberculosis, Extra-pulmonary, Shoulder joint, Physiotherapy.
Nonlinear regimes of the steady Marangoni convection in a thin film heated from below
Authors:   Perm State University, Samoilova Anna E. , Permyakova Evelina V. ,   Perm State University
Published: August 2022

We investigate the dynamics of a thin liquid film that is placed atop a heated substrate of a very low thermal conductivity. The direct numerical simulation of the stationary long-wave Marangoni instability is performed within the system of coupled partial differential equations. These equations were previously derived within the lubrication approximation; they describe the evolution of film thickness and fluid temperature. We compare our results with previous results of the weakly-nonlinear analysis. A good qualitative agreement is observed for values of the Marangoni number near the instability threshold. In the case of supercritical excitation, our results for the amplitudes are described by the square root dependence on the supercriticality. In the case of subcritical excitation, we found the hysteresis. In the vicinity of the instability threshold the film interface is nearly sinusoidal, with two vortices under elevated region. As the supercriticality increases, the nonlinear stationary regimes arise, with a local elevation at the global minimum and with two additional vortices, correspondingly. In a case of subcritical excitation, relatively high supercriticality results in that these regimes evolve into film rupture via the emergence of secondary humps. For the supercritical excitation, stationary regime with doubled wavenumber occurs. We also revealed the transition through the traveling wave between two nonlinear regimes with different high of local humps.
Differential calorimetry of lithium niobate single crystals
Authors:   Perm State University, Spivak L. V. , Sosunov A. V. ,   Perm State University
Published: August 2022

We conducted a series of calorimetric experiments with nominally pure lithium niobate single crystals of congruent composition from different manufacturers and with different cuts, the samples were exposed to temperatures of up to 1100 ℃. For all samples, a temperature feature is observed in the range of 800–900 °C, regardless of their crystallographic orientation. The calculated activation energy of about 150 kJ/mol indicates the diffusion mechanism of the transformation, most likely associated with the high mobility of lithium and niobium ions as well as the possibility of formation of oxygen vacancies in the crystal lattice of lithium niobate. In some cases, this technique can serve as a technological parameter for the manufacture of lithium niobate crystals of optical quality.
A human rights-based approach to implementing Target 11.6 of Sustainable Development Goal 11 in Zimbabwe
Authors: Masekesa Liberty Kudzai
Published: August 2022

In its quest to deal with sustainability challenges continuously posed by rapid urbanisation, the international community reinvigorated the role of local governments as co-global actors in pursuance of the global sustainable development agenda by dedicating to cities Sustainable Development Coal 11 (SDC 11) of the United Nations 2030 Sustainable Development Agenda. SDC 11 is accompanied by ten time-bound targets directed towards making cities and human settlements across the world inclusive, safe, resilient and sustainable by 2030. Reports reveal that Zimbabwe, among other countries, is struggling to give effect to these targets, including Target 11.6 which requires local authorities to contribute towards reducing 'the adverse per capita environmental impact of cities'. Struggling with this target has implications for the enjoyment of environmental rights, among other fundamental rights. As such, using a human rights-based approach, this article explores how the right to a healthy environment entrenched in the 2013 Constitution of Zimbabwe can be used to pursue Target 11.6. Although the huge potential of the human rights-based approach remains untapped in Zimbabwe, the article argues that its adoption in relation to Target 11.6 appears, in theory, to be the most appropriate means for the enjoyment of the right to a healthy environment as local authorities have a shared responsibility to adhere to human rights norms and standards. In light of the commendable precedents set by the judiciary in some cases, local authorities are recommended to consider the implication of legal provisions on the right to a healthy environment in the process of exercising their legislative or executive powers directed towards the realisation of Target 11.6.
Protected areas, community rights and affirmative action: The plight of Uganda's Batwa people
Authors: Paterson Alexander
Published: August 2022

The intersection between protected areas, community rights, statutory legal frameworks and customary law and practice is complex. Several cases heard by members of the African judiciary over the last decade have dealt with this intersection and provided valuable guidance on forging solutions promoting the contemporary conservation discourse that recognises the role of local communities and indigenous peoples in the governance and management of protected and conserved areas. The recent claim brought by the Batwa people of Uganda to land and resources situated in three protected areas provided the judiciary with another opportunity to draw from and contribute to the emerging relevant jurisprudence. This contribution overviews this jurisprudence and its strong link to the contemporary conservation discourse, and critically reflects on the latest contribution to it. It ultimately concludes that while the Ugandan Constitutional Court in the Batwa case missed a clear opportunity to draw from and develop the existing relevant jurisprudence, it did add a new dimension to it in the form of forging solutions through affirmative action redress.
Implications and opportunities of the international refugee protection regime for national human rights institutions in Africa
Authors: John-Langba Vivian Nasaka
Published: August 2022

The upsurge in the global numbers of refugees and asylum seekers since 2015 and the resultant protection failures witnessed particularly in Europe led to renewed debates on the need to reform the refugee protection regime to identify pathways that would enhance protection. Key in these debates was the need to identify actors that could enhance the refugee protection regime, including accountability for failures to protect. Among such actors identified are national human rights institutions. This article situates NHRIs within the nexus between international human rights law and international refugee law to frame an understanding of their role in the refugee protection regime. It then considers the evolution of the international refugee protection regime in light of the emergence of NHRIs and critically reviews their positioning with reference to the mandate of the United Nations High Commissioner for Refugees and the Global Compacts on Refugees and Migration. Specific opportunities at the African regional level are subsequently discussed to support the assertion that NHRIs can perform a specific role in promoting the effective implementation of refugee rights, including as avenues for state accountability.
Promoting civic and voter education through the use of technological systems during the COVID-19 pandemic in Africa
Authors: Mudau Paul
Published: August 2022

A human rights perspective to this article intertwines the rights to information and political participation. It deals with the intersections between the provision of civic and voter education (CVE), and the opportunities and threats pertaining to the feasibility of finding digital solutions for enhanced voter participation in democratic electoral processes during the coronavirus disease (COVID-19) pandemic in Africa. Under normal circumstances and while conducted through physical contact sessions, CVE is aimed at providing citizens with communication, general and life skills to constructively participate in democratic electoral processes. The greater the attendance in CVE events, the greater the conviction that a significant number of participants have been enlightened and encouraged to fully participate. As a result, electoral democracy becomes enriched and consolidated. However, the impacts of the COVID-19 pandemic render the physical training and dissemination of this crucial CVE information cumbersome, principally when considering the strictly-restricted number of attendants at events, consequently placing in disarray the enhancement of voter participation. Electoral management bodies, which are inherently charged with the responsibility for promoting CVE, confront the challenges for securing meaningful voter participation. Reliance on technological systems in the promotion of a consolidated electoral democracy during the COVID-19 pandemic emerges as a measure of last resort. Cognisant of the numerous developmental challenges encountered by many African countries, the feasibility of digital solutions in this instance could be far-fetched. More so, the digital divide and its impacts militate the empowerment of poor voters in remote rural areas where access to technological infrastructure and equipment is distantly slim.
Due process or crime control? An examination of the limits to the right to silence in criminal proceedings in Ghana
Authors: Tufuor Isidore Kwadwo
Published: August 2022

This article examines the extent of participation of accused persons in criminal proceedings in Ghana, particularly in the context of the procedural limits to the right to silence and its associated privilege against self-incrimination. Though normatively set along a libertarian theory that largely insulates the accused from matters of proof, the article finds that the legal regime of the right to silence not only admits of several procedural burden-shifting mechanisms that enjoin accused persons to speak and participate in the proof process, it also permits the drawing of adverse inferences against the accused's exercise of the right to silence in several instances. The analysis extends to a critical evaluation of the benefits of silence in the operational design of the adversarial trial. In that context, it discusses the extent of the accused's beneficial use of the right to silence and finds it an imprudent and legally-uninformed exercise that may deprive the accused person of their right to aggressively partake in the search of facts and evidence and thus of their right to adversarial trial. The article is relevant as it constitutes the first attempt at defining the criminal justice policies underlying the limitations to the right to silence in Ghana. It adds to the existing knowledge on the right to silence in criminal proceedings as it delves into the philosophical underpinnings of the criminal procedure which is increasingly leaning towards a truth-finding and utilitarian ideology away from the core due process theory that generally defines the adversarial criminal procedure.

INTERPRETATION OF THE IMAGE OF AMERICAN PHILOSOPHICAL SCHOOLS IN THE P. V. KOPNIN'S VIEWS
Authors:   Taras Shevchenko National University of Kyiv, Varganov Anton
Published: August 2022

The article is devoted to the interpretations of the images of American schools that existed in Soviet philosophy, especially in the views of the founder of the Kyiv school of philosophy P. V. Kopnin. The relevance of the study is due to the views of the perception of American philosophical schools by the Soviet tradition since modern ideas about the history of American philosophy are largely based on these ideas. Through their own research and peculiarities of perception, the outstanding Soviet philosophers of the Kyiv school developed a paradigmatic vision of the historical and philosophical context of the existence of a particular school. Turning into weight certain features and aspects of individual historical and philosophical phenomena and carrying out a subjective interpretation, P. V. Kopnin formed his own understanding of their essence, developing further guidelines for future philosophical studies of his followers. The study of the results of these interpretations allows, on the one hand, to better understand the vision of the Soviet philosophy of the history of American philosophy, on the other hand, through the prism of this understanding, with the possibility of overcoming it, to explore American philosophical schools from a different angle and to carry out their own interpretation of these images.
SOCIO-POLITICAL AND SOCIO-CULTURAL PRECONDITIONS, THEORETICAL AND METHODOLOGICAL TOOLS OF THE PROCESS OF CHINAIZATION OF MARXISM IN THE SOVIET PERIOD RESEARCHES
Authors:   Taras Shevchenko National University of Kyiv, Yarmolitska Nataliia , Gan Katherine ,   Taras Shevchenko National University of Kyiv
Published: August 2022

The article examines the socio-political and socio-cultural prerequisites of the Chineseization of Marxism in the studies of the Soviet period. The authors analyzed the main concepts, ideas, and approaches in the context in which the research data were carried out. An analysis of the main features of the research of Soviet scientists, who, from the standpoint of orthodox Marxist-Leninist philosophy, highlighted the process of building socialism in China, is given. Emphasis is placed on the worldview and methodological foundations of the philosophical system of Chineseized Marxism, as well as on the socio-political doctrine of "socialism with Chinese characteristics". The conclusions reached by the authors allow us to assert that in the studies of the Soviet period, the theory of building socialism with Chinese characteristics was recognized as the conceptual basis of China's development, the basis of which was Chineseized Marxism, which was carried out through a practical combination of China's modernization and Marxism.
LEXICAL REPRESENTATIVES OF THE CONCEPT OF "BEING" IN THE MONIER-WILLIAMS ENGLISH-SANSKRIT DICTIONARY
Authors:   Taras Shevchenko National University of Kyiv, Hnatovska Нanna
Published: August 2022

The article is devoted to the study of the etymology and semantic connotations of Sanskrit terms: sat, bhāva, sambhava, bhavitṛ, bhavya, bhavat, bhūti, bhūta, sarvabhūta, bhavaka, sattva, sattā, saṃvṛtti, jāstāmātā sampatti, vartamāna, āvitta, āvinna as lexical representatives of the conceptosphere of being in the Sanskrit-English dictionary of Monier-Williams. The method of conceptual analysis is implemented based on the assumption of the determining influence of language culture on the content and nature of philosophical creativity. This study is only the first stage of the project to reveal the way of interpreting "being" in the history of Indian philosophy. The key semantic connotations of this concept in the Monier-Williams English-Sanskrit dictionary are revealed. The semantic connection of the concept of "being" with the concepts: "life" and "time" is defined. In this context, "to live" is to be "someone" in order to embrace "one's place" and play "one's role" that can provide "possession" for "subsistence", and the relationship between "being" and "time" is the concreteness of the existing event that is happening or has happened and belonging to the future that is about to happen. Although we do not trace a transparent connection between the concepts of "being" and "space" in Sanskrit, there are reasons to believe that the first of all, the etymology of the terms of our chosen conceptosphere clearly presents the interpretation of being as a long and a spatially defined location. Noticeable is the fact that the connection between the interpretation of the concept of "being" in Sanskrit and the ethical concept of "good" and aesthetic "beauty" we trace only in terms derived from as and bhū, and at the same time only the terms sat and bhava can be translated as "truth", and the meaning of "essence" we find only in the translation of the terms sat and sattva. This explains the fact why the term sat is considered as close as possible to the "Western" interpretation of the concept of "being". It has been suggested that the polysemy of lexical representatives of the concept of being in Sanskrit and the complexity and variability of the grammar compliance of this language can be interpreted as an obstacle to the extreme problematization of this concept.

Published: August 2022

The following work will attempt to present to the reader the topic of Empiricalization in the recent treatment of Argumentation. An interesting trend that has emerged in the last decade or so concerns empirical turn in the study of argumentation. Empiricalization is the term that describes the attempts to underline the relationship between argumentation theory and argumentative reality by using different qualitative, quantitative, and mixed empirical methods. Currently, there are various empirical approaches in the field of argumentation. The author considers two of them, namely the historical-textual, and the meta-argumentation approaches. In addition to organizing what is already known about empiricalization, this paper also serves the function of suggesting what empirical research is needed to fill in theoretical gaps in the recent treatment of argumentation. In this regard, the purpose of this paper is to provide up-to-date, relevant, and informative discussion about an empirical component in argumentation research. Besides, in the paper, the author through the concept of Empiricalization approach to problems in Philosophy such as how to analyze and evaluate argumentation in philosophical texts.
Detection and correction of equipment biases during engine tests

Published: August 2022

Production tests on test-benches are mandatory before aircraft engines are delivered, as the measurements taken during the tests determine whether the engine meets the requirements. They are essential for both aircraft and engine manufacturers and the latter can use them to obtain a
comprehensive picture of the performance of each engine. Such tests involve numerous measurements, the analysis of which is a challenging task. The study presented in this paper aims to detect possible biases introduced by the instruments used to measure the engines during the tests, especially
the test-bench itself. A method is proposed to correct these biases. At the end, it will be necessary to verify that the data are corrected, ie that the measurements no longer depend on the test-bench on which they were made. This analysis is the follow-up of previous work on thrust tendency
estimation[1].

La enfermedad por coronavirus 2019 (COVID-19) causada por el Coronavirus del Síndrome Respiratorio Agudo Severo 2 (SARS-CoV-2) ha generado un impacto sin precedentes en la salud mundial debido a su rápida propagación desde que fue declarada pandemia el 11 de marzo de 2020 por la Organización Mundial de la Salud (OMS), afectando a millones de personas en más de 200 países1-3. A pesar de que no se ha determinado por completo la inmunopatogénesis de COVID-19, se sabe que el mal pronóstico de los pacientes se asocia a una respuesta antiviral insuficiente durante la fase inicial de la infección, caracterizada por un déficit en la producción de Interferones tipo I (IFNs-I)4, sumado a una respuesta inflamatoria exagerada, que conduce al síndrome de liberación de citocinas5. Esta revisión describe los aspectos inmunológicos más importantes de la COVID-19: los principales mecanismos de activación y evasión de la respuesta del IFN en la infección causada por SARS-CoV-2; la contribución a la gravedad de la enfermedad por parte de la desregulación de citoquinas y la respuesta celular; y algunas de las estrategias terapéuticas que se dirigen a elementos de la respuesta inmune innata.
Tourist Souvenirs: Learning Cultural Identity Representation Through Design
Authors: Rocha Fátima
Published: August 2022

The massification and standardization of souvenirs offered in major tourist destinations around the world seem to compromise the authenticity and representation of the cultural identity that these products intend to evoke. Although the tourist souvenir is a product widely addressed by academic studies in tourism and other social areas, there is a gap in design studies about the value this object has as a representative of unique cultural expressions. In this article, we observe the potential offered by souvenirs as a subject for teaching design, in a didactic exercise focused on valuing cultural identity. In 2009, the city of Rio de Janeiro, Brazil, was preparing itself to host the 2014 FIFA World Cup and the Rio2016 Olympic Games. From 2009 to 2011, three hundred students of the Methods and Processes in Design course, from the Fashion Design degree of SENAI-CETIQT – Chemical and Textile Industry Technology Centre of the National Service for Industrial Learning, were encouraged to develop an innovative souvenir that could represent the local culture. It was possible to notice the relevance of cultural aspects as a determinant factor of differentiation and authenticity in the souvenir design project, in addition to bringing to the students a greater awareness of the role of the designer in creating non-verbal messages about the cultural identity of a nation or locality.

Published: August 2022

Developing pedagogical skills of teachers is an essential objective in teacher education. Although feedback from workplace supervisors is considered crucial for encouraging these skills in the first stages of teachers’ careers, delivering effective and just-in-time feedback is under pressure due to a teacher shortage in secondary education. Recent technological developments allow alternative sources to deliver feedback provided by innovative technologies. However, a comprehensive picture of effective characteristics of computer-mediated feedback (CMF) is lacking. Therefore, this review identifies studies with the aim of deducing a set of design principles for CMF fostering pedagogical skills. Subsequently, all studies were categorized with respect to learning environment characteristics, learning processes and learning outcomes. The synthesis is a set of principles including personalized, immediate and delayed feedback. Finally, a future research agenda focuses on how these principles could optimize innovative technologies to deliver feedback for teachers in daily practice.

Open data and open data ecosystems (ODEs) are important for stakeholders from science, businesses, and the broader society. However, concerns about data sharing and data handling are significant adoption barriers of ODEs that reduce stakeholder participation and thus the success of the initiative. Data governance (DG) is proposed as solution, but requirements of the three stakeholder groups combined are not clear and especially how they can be integrated in one DG concept. This paper develops a framework, supporting elicitation of DG requirements in ODEs. The framework builds on a series of stakeholder workshops and literature research resulting in DG requirements and DG mechanisms. The resulting framework includes five main dimensions: (1) data usability, (2) ethical and legal compliance, (3) data lineage, (4) data access and specified data use, and (5) organizational design.

Although showrooming behaviour is a characteristic aspect of modern omnichannel retailing, our understanding of its antecedents remains limited. In this study, we aim to address this gap in prior research by examining how showrooming behaviour is affected by three different kinds of perceived consumer capabilities: general online shopping skilfulness, mobile online shopping skilfulness, and multichannel self-efficacy. The examination is done by utilising data from 1,024 Finnish consumers, which was collected with an online survey in 2021 and is analysed with structural equation modelling (SEM). In summary, we find mobile online shopping skilfulness to have a strong positive effect on showrooming behaviour, the total effect of general online shopping skilfulness to be statistically not significant, and the effect of multichannel self-efficacy to be negative. In addition, we find several interesting gender and age differences. We conclude the paper with a detailed discussion of the findings from both theoretical and practical perspectives.

Meta-platforms have received considerable Information Systems scholarly attention in recent years. Meta-platforms enable platform-to-platform openness and are especially beneficial to amplifying network effects in highly-specialized markets. A promising emerging context for applying metaplatforms is data marketplaces—a special type of digital platform designed for business data sharing that is vastly fragmented. However, data providers have sovereignty concerns: the risk of losing control over the data that they share through metaplatforms. This research aims to explore antecedents and consequences of data sovereignty concerns in meta-platforms for data marketplaces. Based on interviews with fifteen potential data providers and five data marketplace experts, we identify data sovereignty antecedents, such as (potentially) less trustworthy data marketplace participants, unclear use cases, and data provenance difficulties. Data sovereignty concerns have many consequences, including knowledge spillovers to competitors and reputational damage. This study is among the first that empirically develops a pre-conceptualization for data sovereignty in this novel context, thus laying the groundwork for designing future data marketplace meta-platform solutions.

The article analyzes the causes, results and consequences of economic modernization reforms in Georgia in 2004–2013. The authors examine the starting positions of Georgia’s economy on the eve of reforms and study the main macroeconomic indicators of the country in different periods of its post-Soviet history. The purpose of the research is to identify both the strengths and weaknesses of Georgia’s economic transformation in 2004–2013, and to determine the sustainability of the results achieved. In other words, the question to be answered is whether the post-reform economic system of Georgia was able to withstand the changes in the foreign trade environment (in particular, the fall in prices for Georgia’s main export products – ferroalloys and copper in 2014–2019), and then the economic downturn caused by the COVID-19 pandemic. Having assessed the degree of success and effectiveness of the modernization reforms 2004–2013, the authors conclude that the results were contradictory. On the one hand, the tax reform proved to be highly efficient; significant success was achieved in the privatization of state property (both industry and land), as well as in the expansion of economic rights and freedoms of the population. On the other hand, the anti-corruption measures were only partially successful, as significant results were achieved only at the grassroots level, while systemic corruption (primarily in the higher echelons of government) remained the most serious problem of Georgian society and the state. Similarly, debureaucratization did not affect all sectors of the economy. Thus, while serious progress was registered in the spheres of services, trade and tourism, the debureaucratization and reduction of state regulation in agriculture and industry were less successful.

Agriculture in the Yucatán Peninsula, Mexico, grew last year, and pesticide use problems have been reported; however, there is no information about the use and management of pesticides in farms. In this study, the main pesticides used by farmers were identified in two types of agriculture: open-air (milpa) (OA) and enclosed area (shade house and greenhouse) (EA), in order to evaluate their use and management and the related environmental and health perceptions of users. Surveys (38 questions) were applied to 39 farmers in the study area, which consisted of 14 localities in Yucatán State. The most cultivated products were habanero pepper (Capsicum chinense) for enclosed-areas and maize (Zea mays) for open-air agriculture. The use of 33 active ingredients was reported. Some of them have restrictions in México (i.e., dicofol and methamidophos). Paraquat was the most used of all pesticides reported. Organophosphorus pesticides (OP) were the most used. Farmers know about the environmental and health risks related to pesticide use; however, a lack of knowledge about the misuse of these products was evident. The surveys showed deficiencies in personal protection during application and incorrect disposal of empty containers and wastes. The analysis showed that the behavior of farmers about pesticide management and their perception of damage to health and the environment were multifactorial. The results conclude that farmers’ personal aspects (i.e., language, education) are the leading cause of problems associated with pesticide misuse and the lack of information and training, representing a risk for human health and the environment.
Effect of the Trip-Length Distribution on Network-Level Traffic Dynamics: Exact and Statistical Results
Authors: Laval Jorge
Published: August 2022

This paper presents additional results of the generalized bathtub model for urban networks, including a simpler derivation and exact solutions for uniformly distributed trip lengths. It is shown that in steady state this trip-based model is equivalent to the more parsimonious accumulation-based model, and that the trip-length distribution has merely a transient effect on traffic dynamics, which converge to the same point in the macroscopic fundamental diagram (MFD). To understand the statistical properties of the system, a queueing approximation method is proposed to compute the network accumulation variance. It is found that (i) the accumulation variance is much larger than predicted by traditional queueing models, due to the nonlinear dynamics imposed by the MFD, (ii) the trip-length distribution has no effect on the accumulation variance, indicating that the proposed formula for the variance might be universal, (iii) the system exhibits critical behavior near the capacity state where the variance diverges to infinity. This indicates that the tools from critical phenomena and phase transitions might be useful to understand congestion in cities.
Investigating the Physical Properties of Paper Produced by Blending of Water Hyacinth and Dried Flowers

Published: August 2022

The production of paper is a key component for global civilization. Around 300 million tonnes of paper being produced every day globally, with matured pulp wood being the major contributor. Due to rising demand for paper and the depletion of available wood resources, Researchers are now focused on finding alternative non-wood resources that are suitable for pulp and paper production. The current study aims to produce eco-friendly and biodegradable paper using a combination ofEichhornia crassipes(water hyacinth) and dried flowers. Water hyacinth is considered as a lignocellulose plant which contains 57% ligno-cellulose and dried flower contains 40% cellulose, which is the prime source for paper production. Various sections of water hyacinth, including wet and dry petiole, leaves and root were blended with dried flowers through soda process. Then, the physical properties and FTIR analysis was carrier out to identify the quality of the paper produced. The paper produced from root and dried petiole has a lower thickness (1.0mm and 0.5mm) than other mix proportion. The opacity of the leaves was found to be (0.5% light passing) and the root (0.7% light passing). Also, the dry petiole paper and root has a good dry-tensile strength of 1.30Kpa and 1.20Kpa respectively. Hence, paper made from dry petiole and root was found to be efficient and suitable for paper industry.
