Lignocellulolytic Microbial Systems and its Importance in Dye Decolourization: A Review
Authors: Das Somnath , Gole Ankita , Chakraborty Annesha , Mal Supriyo , Rudra Shilpa , Ghosh Dipankar
Published: May 2023

Effluents containing dyes from different industrial sectors pose a serious threat to the environment. Different physicochemical strategies are being carried out in industry to reduce the toxicity of dye-containing waste so that dye-mixed wastewater can be further utilized in agriculture or irrigation purposes in water-scarce areas. But those techniques are economically not feasible. There is an alternative mechanism present in biological systems that are biocatalysts which is eco-friendly, low cost, and sustainable. Lignin peroxidase, Laccase, Manganese peroxidase are oxidoreductase classes of enzymes with the ligninolytic ability and are potential biocatalysts for the degradation of environmental toxicants like dyes. Besides ligninolytic enzymes, cellulase, pectinase are also powerful candidates for dye decolourization. Most interestingly these biocatalysts are found in a variety of microbial monoculture as well as in mixed microbial consortia. The consortia are able to reduce the organic load of dye-containing industrial effluent at a higher rate rather than the monoculture. This article critically reviews the efficacy of lignocellulolytic enzymes in dye decolourization by both monoculture and consortia approaches. In addition, this review discusses the genetically and metabolically engineered microbial systems that contribute to dye decolourization as well as put forward some future approaches for the enhancement of dye removal efficacy.
Studies on Diversity of Bacterial Diseases and Occupational Risks through Mudcrab Aquaculture in West Bengal
Authors: Saha Sanjib , Pradhan Debajyoti , Dash Gadadhar
Published: May 2023

In West Bengal, the two most tradable species of mud crab (Scylla sp.) are available due to high market demand in local as well as foreign markets. Scylla sp. is an important (ecological, nutritional, and economical) bioresource in India including West Bengal. Juveniles and adult mud crabs are selectively collected by coastal area common people or fisherpersons for culturing in ponds and crabs are traded locally or internationally. Different coastal districts’ people of West Bengal, mainly North-24 Parganas, South-24 Parganas, and Midnapur are inextricably linked to the crab as being culture that serves as their alternative occupation/livelihood. Various bacteria are recorded as related to mud crab as being infections. Some of the bacteria may transmit from mud crabs to humans and cause mainly gastric-related diseases and septicemia by the transmission of virulent genes and microbes from unsafe water to the crab and then to humans. Such pathogenic infections like vibriosis without proper treatment can result in mass mortality of Scylla sp. The potential for disease transmission to people from mud crabs has been demonstrated by a number of significant variables and the water surrounding them. Eating raw or undercooked crab, ingesting water or other substances contaminated with infected crab excrement or mucus, and coming into touch with the infectious agent through open wounds or contact skin scratches or abrasions are the main sources of bacterial infections. It is reported that bacteria transferred by consuming contaminated water with infected organisms or handling are more than 10%. Crab fisherpersons and farmers, in general, have less environmental awareness, and scientific-based knowledge and for this reason, they face various types of occupational hazards including zoonotic septicemia. The present article investigates the distribution of different zoonotic bacteria and their potential threats, both for mud crabs and the human population.

Published: May 2023

Abstract: This paper explores the declining population of birds in India due to human activities such as deforestation and urbanization, which has led to a significant decrease in the number of bird nests. With over 1,300 bird species in India, it is essential to conserve their populations and nesting habitats. The paper studies the problems faced by birds in natural nests and proposes an innovative approach to designing smart nests that can improve nest success rates and promote bird conservation. The research methodology includes contextual inquiry, flow modeling, and a cultural model to understand the regional culture of birds and their significance. The study analyzes the process followed by birds to build a natural nest and identifies decision points, dependencies between tasks, and the roles of birds and interference by humans and predators in their nests. The paper also presents different innovative approaches to nest design and construction, such as the use of recyclable materials, technology, and green roofs. Ultimately, this paper aims to raise awareness of the importance of bird conservation and provide a roadmap for creating better nesting habitats for birds in India

Published: May 2023

Abstract: Automation is a technology concerned with the application of mechanical, electronic and computer systems. This article provides an overview of the various methods and techniques used for restaurant automation. In restaurants, menus are available on every table. The customer can refer it and order through the waiter. The customer has to wait for the waiter. Even a restaurant manager finds it difficult to keep up with changing menu prices. At the same time, adding a new menu to the same card becomes a tedious job for whoever is responsible for this work, as changing the menu within a short period of time can lead to an increase in costs.

Authors: Shah Jainam B , Jadav Rita M.
Published: May 2023

Abstract: Due to the growing need for water for uses such as hydropower, farming, and drinking purpose among others, water is becoming an endangered asset. Water is increasingly needed for a variety of reasons as the population grows. On the contrary, the accessibility of water resources is limited. To determine crop water requirement for any crop and evaluate irrigation scheduling for effective water management, crop coefficients and reference crop evapotranspiration must be calculated. The purpose of this research is to determine crop water requirement of Cotton, Wheat and Sesame for Surendranagar Region and Prepare Irrigation Scheduling using the FAO-56 Penman-Monteith Method using FAO CROPWAT 8.0 Software. Meteorological data for Surendranagar region such as maximum and minimum temperatures, mean relative humidity, sunshine hours, and wind speed, are obtained from Wadhwan taluka of Surendranagar used to calculate reference crop evapotranspiration. Crop water requirement for Cotton using CROPWAT 8.0 model is obtained 876.3 mm/dec Crop water Requirement for Wheat is obtained 543.9 mm/dec and Crop water Requirement for Sesame is obtained 529.6 mm/dec This finding may be helpful for agricultural planning and effective irrigation control in the growing of cotton, Wheat and Sesame.
Efficient variational synthesis of quantum circuits with coherent multi-start optimization
Authors: Nemkov Nikita A. , Kiktenko Evgeniy O. , Luchnikov Ilia A. , Fedorov Aleksey K.
Published: May 2023

We consider the problem of the variational quantum circuit synthesis into a gate set consisting of the CNOT gate and arbitrary single-qubit (1q) gates with the primary target being the minimization of the CNOT count. First we note that along with the discrete architecture search suffering from the combinatorial explosion of complexity, optimization over 1q gates can also be a crucial roadblock due to the omnipresence of local minimums (well known in the context of variational quantum algorithms but apparently underappreciated in the context of the variational compiling). Taking the issue seriously, we make an extensive search over the initial conditions an essential part of our approach. Another key idea we propose is to use parametrized two-qubit (2q) controlled phase gates, which can interpolate between the identity gate and the CNOT gate, and allow a continuous relaxation of the discrete architecture search, which can be executed jointly with the optimization over 1q gates. This coherent optimization of the architecture together with 1q gates appears to work surprisingly well in practice, sometimes even outperforming optimization over 1q gates alone (for fixed optimal architectures). As illustrative examples and applications we derive 8 CNOT and T depth 3 decomposition of the 3q Toffoli gate on the nearest-neighbor topology, rediscover known best decompositions of the 4q Toffoli gate on all 4q topologies including a 1 CNOT gate improvement on the star-shaped topology, and propose decomposition of the 5q Toffoli gate on the nearest-neighbor topology with 48 CNOT gates. We also benchmark the performance of our approach on a number of 5q quantum circuits from the ibm_qx_mapping database showing that it is highly competitive with the existing software. The algorithm developed in this work is available as a Python package CPFlow.
A method of indefinite resource factors and systemic correction of time conflicts in construction schedules
Authors: Bolotin Sergey Alekseevich , Bokhan Khaytam Abdulrazzak , Dadar Aldyn-kys Hunfevna , Biche-оol Khenzig Vladislavovna
Published: May 2023

When construction work schedules are developed, numerous time parameters are taken into account. Even full account of these parameters cannot guarantee a feasible work schedule. The identification of time conflicts, arising in this case, and their solutions, is a rather labour­intensive process even in the context of computer­aided work scheduling performed using project management software. The analysis and elimination of time conflicts, presented in the article, are based on the improvement of the method of uncertain resource factors. The proposed methodology is focused on feasible construction work scheduling in the case when restrictions, associated with time characteristics, do not allow to set up a construction work timeline. The main feature of the improved method of indefinite resource factors is the simplex algorithm used to find a basic solution in the case of a negative slack, represented in the form of equations, which in the aggregate represent an invalid basic solution. Negative values of base variables, obtained in this case, allow to design integrated regulatory impacts, that allow for the systemic generation of feasible construction schedules that take account of time constraints having an adverse effect.

Real estate in the focus of development priorities 2030 (based on the materials of the Gaidar Forum 2022)
Authors: Yaskova Natalya Yurevna
Published: May 2023

The annual Gaidar Forum traditionally opens the agenda for the development of the national economy for the next year with an eye to the implementation of strategic goals. The dynamism of modern economic processes requires not just taking into account external challenges and internal problems, but forecasting chan­ges in the global economic landscapes, modeling systemic changes in the allocation of productive forces and the possibilities of integrating Russia into existing and emerging technological chains. The intensive development of new industries, the targeted focus of investments on investments in the knowledge economy, the transformation of the industrial, transport, energy and housing and communal framework of capital funds set a new rhythm of construction. Its ultimate goal is to create a real estate sector that provides balanced spatial development, accelerated energy transfer and advanced development of human capital as a basis for impro­ving the comfort, quality and standard of living of citizens.

The range of topics discussed touched upon almost all strategic objectives of achieving the goals of national projects. Priorities for the development of the real estate sector were announced in various contexts: digital and administrative transformation, scientific and personnel support, formation of a comfortable urban environment, housing construction and mortgage boom, master planning tools, etc. At the same time, behind the obvious thematic favorites of the new rhythm of construction and transformation of the real estate sector, a number of important problems remained in the “shadow” of panel discussions. Among them: the euphoria of housing construction and the danger of possible imbalances, professional transformation and the challenges of digitalization, the risks of human-centered and distance education, the discomfort of the business environment in real estate, the vacuum of modern tools for resolving economic disputes and coordinating economic interests, etc.

Developing a view on the priorities of the development of the real estate sector in terms of ensuring the rights of shareholders and the transition to project financing, the issues of ensuring the quality of housing and communal services, further capitalization of the housing stock, mechanisms for resolving contradictions between tenants and management companies, etc. remained outside the Forum. These issues, being an integral part of a comfortable business environment and the living environment of citizens, actualize a new context of development from Priorities to Parities of economic interests and tracks of development of “power – business – man”.

Открытие в конце XX века анаммокс-бактерий вызвало дос­таточно большой прогресс в разработке новых технологий очистки сточных вод. Процессы с участием данного вида бактерий могут протекать как на очистных сооружениях городов и поселков, так и на промышленных предприятиях в зависимости от степени загрязнения поступающих сточных вод. Данная статья посвящена сравнению различных технологий, которые сегодня предлагаются на рынке для различных целей. Сообщество микроорганизмов Anammox интересно перспективностью очистки сточных вод, насыщенных соединениями азота, но бедных органическими веществами, именно с такими сточными водами не справляются классичес­кие методы удаления биогенных элементов. Выявлено, что анаммокс-бактерии играют значительную роль в круговороте азота в природе, а также в процессе глубокой биологической очистки сточных вод от соединений азота. Рассмотрены различные технологические схемы анаммокс-процесса, которые различаются кислородными условиями, набором сооружений, а также рекомендуются для очистки сточных вод с разными концентрациями загрязнений в сточных водах на входе в очистные сооружения. В результате были выявлены перспективные направления развития в этой области. Показано, что качество очистки сточных вод, которое может быть получено использованием изученных бактерий, может соответствовать нормативным показателям.
Системные причины погрешности и расхождений при оценке стоимости промышленного актива независимыми подходами и рекомендации для согласования результатов оценки

Published: May 2023

Оценка стоимости промышленных активов производится для принятия решений при формировании комплексов этих активов в составе бизнесов действующих предприятий, a также при создании самих активов, при их приобретении, при списании на утилизацию и в иных обстоятельствах. Погрешность оценки и расхождение результатов, найденных независимыми подходами, могут выступать показателями качества оценки. База определяемой погрешности оценки стоимости должна в зависимости от возраста промышленного актива и его накапливаемого износа корректироваться, поскольку непосредственно стоимость актива в пределах его долговечности с возрастом снижается до нуля и поэтому не может служить базой относительной погрешности оценки. Причинами несоответствия стоимости промышленного актива ее значениям, найденным независимыми подходами, являются как приближенность исходных данных, которыми при оценке заменяются характеристики общей системы, в которую оцениваемый актив входит как подсистема, так и методологические различия стоимости как нормативного понятия и стоимости как совокупности методов ее нахождения с использованием независимых подходов. Для согласования результатов, найденных каждым независимым подходом, производится анализ их соответствия адекватным методологическим принципам оценки и свойствам промышленного актива. С учетом свойства накопления износа и ограниченной долговечности актива распределение стоимостных значений, полученных затратным и доходным подходами, при согласовании этих значений может быть рационализировано с использованием предложенного метода. После экспертного определения весового коэффициента для учета результата, полученного сравнительным подходом, при итоговом согласовании вклады результатов оценки независимыми затратным и доходным подходами рассчитываются соразмерно переносу накапливаемого чистого дохода в стоимость имущественного комплекса, к которому оцениваемый промышленный актив принадлежит как элемент системы.
Assessment and modelling the dynamics of building materials prices in the current conditions
Authors: Uvarova Svetlana Sergeevna , Belyaeva Svetlana Viktorovna , Bolgov Vladimir Aleksandrovich
Published: May 2023

Construction, which is the driver of economic development in the current crisis conditions, needs to determine the correct cost and sufficiency of material resources, as well as systematic forecasting of price dynamics in order to plan the implementation of investment projects. High material capacity of construction products, along with the specificity of its pricing, leads to the necessity of not only keeping sufficient accuracy of quantitative and cost calculations regarding basic construction materials but also predicting the dynamics of cost in order to determine the volume of capital costs and accounting for the cost of work. The unstable dynamics of the cost of construction materials in 2022, caused by foreign policy pressure, requires the systematization of the factor space in order to predict trends more reliably. The factor space of the price dynamics of construction materials has undergone fundamental changes, starting with the impact of the coronavirus pandemic, and further due to changes in the geopolitical situation, sanctions pressure from unfriendly countries and corresponding changes in the economic principles of globalization, the transformation of the global and domestic logistics system, as well as the actions of local country and industry scale predictors. The authors have proposed a system of factors affecting the cost of building materials, structures and products in modern conditions, on the basis of the factor analysis the prices of basic building materials (armature and concrete) have been corrected by the expert method, a scenario forecast of price dynamics has been made. The authors substantiate the necessity for calculation-expert forecasting in conditions of high uncertainty and variability of forecasting results. In general, in the short term, a moderate upward trend in the cost of basic building materials with a rather high value coefficient of variation, explained by the strong influence of non-economic factors on the price.

Pharmacokinetic Evaluation of Telmisartan and Cilnidipine Bilayer Tablet in A Rabbit Model
Authors: Kadu Pooja , Zalte Amar , Gulecha Vishal
Published: May 2023

Hypertension is a chronic medical condition affecting a significant proportion of the global population. It is a major risk factor for cardiovascular diseases, stroke, and kidney failure. Telmisartan and cilnidipine combination are commonly used in managing hypertension due to their complementary mechanism of action. Therefore, a bilayer tablet design that enhances the pharmacokinetic profile of cilnidipine as a sustained-release drug while telmisartan act as an immediate-release drug may provide a better therapeutic option for hypertension management. We aim to evaluate the pharmacokinetic parameters of the bilayer tablet of Telmisartan and Cilnidipine. Our objective is to observe the bioavailability of the bilayer tablet in rabbit plasma. The formulation aims to achieve an immediate release effect for Telmisartan and a sustained release effect for Cilnidipine. The solubility and bioavailability of Telmisartan were enhanced by complexation with beta-cyclodextrin. To achieve our aim, we observe the drug concentration in rabbit plasma. Telmisartan is an angiotensin receptor blocker, while Cilnidipine is a calcium channel blocker. The pharmacokinetics of the drugs were evaluated in New Zealand rabbits following oral administration. Systemic drug bioavailability was assessed, and an HPLC method was developed to estimate Telmisartan and Cilnidipine's plasma concentration simultaneously. A Gemini C-18 column (250 mm X 4.6 mm X 5 microns) Phenomenex was used for peak separation. The mobile phase consisted of acetonitrile with phosphate buffer pH 3.5 v/v, with a flow rate of 1.5 ml per minute. The calibration curve analysis indicated a correlation coefficient of 0.9996 and 0.9997 for Telmisartan and Cilnidipine, respectively. The pharmacokinetics of the optimized batch, including Cmax, Tmax, and AUC values, were compared to those of the pure drug. Drug concentration was detected using a DAD detector with an excitation wavelength of 241nm. No interaction was observed between the drugs and excipients. The in-vivo study of the formulation showed higher bioavailability, indicating that the developed bilayer tablet formulation could be an effective means of delivering Telmisartan and Cilnidipine.

Published: May 2023

Este artigo busca compreender como os corpos femininos que aparecem em imagens jornalísticas dos protestos da “Primavera Latina” podem ser compreendidos como repertórios de ação política. A partir da articulação entre a noção de repertório como performance (TILLY, 2008) e a teoria performativa de assembleia (BUTLER, 2016), realizou-se uma análise visual de fotografias publicadas em sites jornalísticos brasileiros sobre protestos de diferentes países latinos ocorridos em 2019. Identificamos três tipos de repertórios em comum: a) a configuração de quem é o povo a partir dos corpos na rua; b) a vulnerabilidade dos corpos femininos expressa em confrontos especialmente envolvendo autoridades policiais e c) a vulnerabilidade acionada como potência política, a partir de performances, corpos em luta, corpos mensagens, expressão da maternidade e símbolos.

Published: May 2023

Este documento expone ventajas que pueden generar la transparencia y el acceso a la información pública a la sociedad. Estos derechos no pueden descansar sólo en la legislación, sino requieren de acciones, objetivos, metas y programas que lo hagan efectivo. Se entiende que no sólo debe observarse a nivel constitucional y legal la evolución de estos, sino atender la implementación de políticas públicas como generadoras de la ciudadanización de los mismos, creando confianza en los sistemas de rendición de cuentas, fiscalización y de responsabilidades, así como su enraizamiento en la sociedad, porque una sociedad informada y participativa coadyuva en el crecimiento de su país. En ese sentido, este documento vincula el derecho de acceso a la información y transparencia como un mecanismo democrático en el que el binomio de Estado y ciudadanía prevean condiciones de mejora a partir de la información suscitada durante una pandemia.

Published: May 2023

La economía colaborativa surge con el enfoque de ayuda mutua, pero este enfoque se profundiza en las relaciones de las empresas y personas a través de los avances tecnológicos. Por lo anterior, en la actualidad, la economía mundial está pasando por un proceso de reorganización en su cadena de valor, caracterizándose por el uso de tecnologías digitales que generan una transformación en el estilo de vida de los seres humanos, impactando en la economía y la sociedad.

En el caso latinoamericano, los países que despuntan bajo este modelo económico son Brasil y México, seguidos de cerca por Perú y Argentina. Por su parte Colombia, se encuentra en pleno estado embrionario en materia de leyes, dado que no existe un marco legal estructurado lo cual ha llevado a una serie de situaciones de carácter económico y social que han llevado a encontrar los dos esquemas económicos.

Esta investigación buscó determinar los hábitos de uso de las empresas de transporte urbano que operan bajo el esquema de economía colaborativa en Bogotá y México, en jóvenes universitarios. Se puede concluir que no existen diferencias significativas por ciudades, lo cual lleva a suponer que este tipo de servicio podría implementar estrategias de mercadeo de manera transversal para mejorar su competitividad con respecto al servicio de transporte tradicional.
Aproximación cualitativa al estudio del federalismo fiscal
Authors: Hernández Salinas Jose Antonio
Published: May 2023

This paper consists of showing a partial progress of the research project entitled "Fiscal federalism and political change" with special emphasis on data collection techniques, understood as the set of alternatives that the researcher has to recover significant information according to the objective of the study (Álvarez-Gayou, 2008). For this purpose, the ontological, epistemological and methodological foundation of the non-directive interview and discourse analysis is analyzed. The first, according to Guber (2001), is a social relationship in such a way that the data provided by the interviewee are the reality that the interviewer builds with the interviewer in the meeting. While the second highlights the need to frame the study of social processes in their historical contexts, rejects universal and generalizable explanations and opts for specific social models and for the emphasis on contradictions and transformations against linear visions (Gordo & Serrano, 2008).

On the other hand, the importance of reflexivity is analyzed, as a critical stance that allows the researcher to carry out decisions within the framework of constant analysis. In this way, the choice of any data recovery technique must be based on a critical stance; that is, from reflexivity and taking into consideration the coherence and harmony between its ontological, epistemological and methodological aspects.

INTEGRATED FAULT TOLERANT CONTROL: A CONCEPTUAL OVERVIEW
Authors: Farrokhi Mohammad , Sabbaghian-Bidgoli Farzaneh
Published: May 2023

In this paper, a conceptual overview of the Integrated version of
Fault-Tolerant Control is presented. When dealing with uncertainty, the
interconnected design needs an integrated approach to make a balance
between performance and robustness. Indeed the integrated approach is
very significant for the design and development of fault-tolerant
control schemes. In this paper, the Integrated Fault-Tolerant Control
(IFTC) approaches are investigated in two FDI-based IFTC and FE-based
IFTC classes depending on the applications of either Fault Estimation
(FE) or Fault Detection and Isolation (FDI) techniques. These two
classes are delicately distinguished and reviewed from the integration
strategy’s perspective and according to the design methodology criteria.
A comparison of these categories is concisely conducted. The integration
is manifested in the coupling of FE and FTC, and the synthesis of the
FDI unit. Moreover, the history of “integration” theory including its
development process according to today’s industry requirements, and its
successful consequences that have been noticed in recent years are
presented to make an overall vision in this area.

Single-model initial-condition large ensembles are powerful tools to
quantify the forced response, internal climate variability, and their
evolution under global warming. Here, we present the CMIP6 version of
the Max Planck Institute Grand Ensemble (MPI-GE CMIP6) with 30
realisations for the historical period and five emission scenarios. The
power of MPI-GE CMIP6 goes beyond its predecessor ensemble MPI-GE by
providing high-frequency output, the full range of emission scenarios
including the highly policy-relevant low emission scenarios SSP1-1.9 and
SSP1-2.6, and the opportunity to compare the ensemble to complementary
high-resolution simulations. First, we describe MPI-GE CMIP6, evaluate
it with observations and reanalyses and compare it to MPI-GE. Then, we
demonstrate with six novel application examples how to use the power of
the ensemble to better quantify and understand present and future
climate extremes, to inform about uncertainty in approaching Paris
Agreement global warming limits, and to combine large ensembles and
artificial intelligence. For instance, MPI-GE CMIP6 allows us to show
that the recently observed Siberian and Pacific North American heatwaves
would only avoid reaching 1-2 year return periods in 2071-2100 with low
emission scenarios, that recently observed European precipitation
extremes are captured only by complementary high-resolution simulations,
and that 3-hourly output projects a decreasing activity of storms in
mid-latitude oceans. Further, the ensemble is ideal for estimates of
probabilities of crossing global warming limits and the irreducible
uncertainty introduced by internal variability, and is sufficiently

Background: Critical Care Nurses (CCNs) provide care to acutely and critically ill patients and their families. Psychological and social factors at work are potential contributors to the health and wellbeing of employees such as critical care nurses working in intensive care units. Studies shows that poor working environments may lead to stress and impaired health for the CCNs, and that work factors may affect both level of competence and patient safety.
Aim: The aim of this study was to investigate critical care nurses' perceptions of psychological and social factors at work.
Method: A survey to investigate Critical Care Nurses' (CCNs') perceptions of psychological and social factors at work. All the CCNs (n = 240) working in 15 ICUs in four Norwegian hospitals were invited to answer the General Nordic Questionnaire for Psychological and Social Factors at Work (QPSNordic). Data was collected during three weeks in Spring 2016 and analysed with descriptive statistics, and parametric and non-parametric tests.
Results: In total 103 CCN completed the questionnaire (43%). The participants responded that they sometimes or rather often faced high job demands (3,09). They very often met positive challenges at work (4,41), though they rather seldom controlled decisions about their work (2,44) or control of work pace (2,32). They rather often had a perception of mastery of work (4,12).
Conclusion: The result of this study suggests that participants experienced high expectations regarding quantitative- and decision demands, but less control at work. They rather seldom or sometimes got information about the quality of the work they performed. Nevertheless, they found their work challenging in a positive way and experienced a strong sense of mastery.
Making Rural Areas Attractive for Teachers and Principals:Putting Rural Educational Settings on the Agenda

One cornerstone in the ‘Nordic model of education’ is equal opportunities in education (Frønes et al., 2020), however, the curricula of the Nordic countries are adapted to urban environments (Bæck, 2016). Regional-spatial aspects of education therefore need to be identified to find solutions to equal education. In this re-analysis of two research projects in Sweden and Finland, new insights are highlighted regarding how to develop nationwide equal education. The study proposes establishing supportive structures in the education of teachers and principals and in their continuing professional development in order to bring about equal education.

This article aims to investigate how Nordic countries – exemplified by Denmark, Finland, and Sweden – govern the education and inclusion of newly arrived students. Approaching this through policy as text and practice, we identify the subject positions of the newly arrived students. Our research data consist of national policy documents, legislation, and evaluation reports on the education of newly arrived students, which we compare and analyse. We conclude that newly arrived students are subject to underachievement, bullying, discrimination, and at risk of not continuing their education. Despite all good intentions the Nordic policies do not seem to include all students.
When Nordic Education Myths Meet Economic Realities: The “Nordic Model” in Education Export in Finland and Sweden
Authors: Rönnberg Linda , Hinke Dobrochinski Candido Helena
Published: May 2023

We analyse policy rhetoric on education export in Finland and Sweden as a lens to explore the multifaceted Nordic model in education. We also examine how the Nordic dimension in education is represented in Finnish and Swedish education exports. Our findings highlight that, while education export approaches differ considerably between the two countries, both contexts provide opportunities for private edu-business actors to thrive, thereby sustaining the global education industry (GEI). Education export is rhetorically positioned in relation to both the national and the Nordic contexts in specific ways, with implications for how Nordic education is framed in the globalised economy.
Combination of 3D solid finite elements with rotation-free beam elements for non-linear analysis of fiber reinforced polymer rebars

Published: May 2023

We present a combination of three dimensional (3D) solid elements and rotation-free beam elements for non-linear analysis of fiber-reinforced polymer (FRP) of rebars. The matrix material is modelled by 3D solid elements while the fibers are modelled with rotation-free beam elements. The absence of rotation variables in the beam elements allows the straightforward coupling of 3D solid and beam elements using a formulation with displacement nodal degrees of freedom only. Both solid and beam elements are formulated in an updated Lagrangian description. The behavior of the matrix and the fiber material are modelled with an elastic-damage model. The efficiency and accuracy of the combined 3D-beam element formulation are verified in examples of application to the analysis of FRP rebars up to fracture in axial, bending and shear tests for which experimental results are available.

The research aims to determine the effectiveness of students' mathematical critical thinking skills using quizizz with PBL with ethnomathematics nuances. The type of research that has been used is quantitative with quasi-experimental methods. One group pretest-posttest research design. Students are given a pretest and intervention through the use of quizizz, after which a posttest is carried out. The research sample was 55 grade IV elementary school students using the saturated sampling technique. The research instrument was a multiple choice test, while data analysis used an independent sample T-Test with a difference test of Sig = 0.000. The results showed that the experimental class mean was 80.82, the control class was 74.14. This proves that the application of quiziz in PBL with ethnomathematics nuances is very effective in increasing student learning independence (self-confidence, always prepared, daring to appear in front, confident in one's abilities, and not afraid to try). Therefore, the application of quiziz with PBL with ethnomathematics nuances can improve students' critical thinking skills.
