Authors: Enascuta Cristina-Emanuela , Oprescu Elena-Emilia , Radu Elena , Somoghi Raluca , Lavric Vasile
Published: February 2023

Fish oils with a high content of polyunsaturated fatty acids (PUFAs) are gaining increasing interest in the food and nutraceutical industry, due to their important functional properties for human beings� health improvement. The most important PUFAs have at least two double bonds placed on the carbon chain. These include ?-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahaxaneoic acid (DHA).
Microencapsulation is a technique used to protect the bioactive compounds from oxidative damage, to ensure their controlled release and to activate the synergistic effect of the ingredients, if it exists.
In this context, the microencapsulation process of fish oils rich in PUFAs using alginate was studied, in the presence and the absence of an ultrasonic (US) field. Both BoxBehnken design of experiment technique and the Response Surface Method were used, to investigate the influence of the process parameters and to optimize the operating conditions. The operating parameters under investigation were the sodium alginate to fish oil ratio, the calcium chloride concentration and time being the objective. The fish oil microspheres had a homogeneous round shape, a diameter of 0.12 � 0.02 mm. Physicochemical description of microcapsules was performed using modern characterization methods.

Sinorhizobium meliloti are agriculturally valuable species of soil bacteria that form nitrogen-fixing symbiosis with alfalfa plants. Global climate changes lead to an increase of agricultural areas subjected to salinity. Current knowledge about about high-salt stress impact on soil saprophitic root nodulated microsymbionts of legumes is weakly studied and rhizobia gene pool responsible for salt tolerance are fragment and far from clear. An increase of bacteria nonspecific resistance (immune status) to unfavorable stress factors can occur through the induction of defense mechanisms like restrictionmodification systems and CRISPR/cas systems which are aimed to protect bacteria cells from bacteriophages widespread in soil microbiome.
The aim of this research was to evaluate the role of the megaplasmid pSymA in the formation of ecological genome of S. meliloti, which is related to stress tolerance and to determine the location of elements of adaptive immune systems protecting root nodule bacteria against external foreign DNA. The analysis was done on 11 genes, products of which involved in response to ion stress and synthesis of osmoprotectors. It was found that 6 out of 11 genes were found in the genomes of all analyzed S. meliloti strains, while it was not a case for other 5 genes. It was found that, unlike chromosome, megaplasmid I of S. meliloti accumulated copies of 4 from 5 genes, except kdpA gene, which is represented by a single copy and localized on megaplasmid I in all so far studied strains. It was predicted that closest phylogenetic relatives of genes whose products are involved in response to ion stress as well in synthesis of osmoprotectors are homologous genes of closely related S. medicae species. The exception was for betI2, for which the closest phylogenetic relative was homologous gene of Klebsiella pneumonia, and another exception is kdpA gene introduced onto megaplasmid-I from actinobacteria. Regarding elements of immune systems it was revealed that nonsymbiotic plasmids of S. meliloti harbored incomplete elements of RMS-I, -II, and - III systems, while the 4 complete RMS-IV systems were detected on a single plasmid. It was found out that corresponding methylases had similarities with similar enzymes detected in nitrogen-fixing strains of Agrobacterium tumefaciens, Mezorhizobium sp., Bradyrhizobium sp. CRISPR sequences were not detected on megaplasmid-I, while they were on chromosome, megaplasmid-II and on cryptic plasmids. So, it was concluded that megaplasmid-I of S. meliloti are enriched in copies of genes related to osmotic stress tolerance, but it role in immune status of rhizobia is requested further elucidation.

Published: February 2023

Requirements relating to the quality of the flue gases produced have become more and more stringent in recent years. This is why the electricity producers, especially those using coal-fired units, have been forced to introduce additional environmental technologies. However, most of the coal-fired power plants and waste incineration plants in the Czech and Slovak Republics are following the same path, in particular for economic reasons. They are introducing the selective non-catalytic reduction of nitrogen oxides (SNCR). This method is based on the reduction of nitrogen oxides by injecting a solution of urea or ammonia water into the combustion chamber of the combustion unit.
The captured fly ash is thus in direct contact with the injected agent. Direct contact of the high-temperature fly ash with the injected medium results in increased amounts of ammonium salts in the fly ashes that have undergone the SNCR process. The ammonium salts contained in fly ash then react very quickly with alkaline substances, such as cement in a concrete mix, producing gaseous NH3. This gas is characterized by a very unpleasant odour. Therefore, when the fly ash is used the hygiene limits might beexceeded.
Very often, but it is not clear whether the fly ash brought to the concrete plant has passed the SNCR mechanism or not. That is why a quick orientation method for detecting the presence of ammonium ions in fly ash was designed and verified. Based on the result of the analysis using this method, it is possible to decide at the concrete plant whether or not the fly ash will be admitted to the silo of the concrete plant. The article briefly describes the methodology of the analysis, highlighting the advantages of the proposed method.

Published: February 2023

Lately, there is a growing need for humanity to get closer to nature and to a way of life so that the negative impact on it to be as small as possible. One cannot talk about durable development without taking into account the sustainability criterion which is essential in all areas of activity. Traditional constructions made of masonry elements from unburned clay or other vernacular materials, using sheep wool mattresses for thermal insulation, successfully meet the conditions imposed by this criterion. Constructions made of natural materials, ensure the responsible use of non-renewable natural resources, the possibility of reuse and recycling of materials, contribute to environmental protection and pollution reduction, are energy saving and provide an hygienic, pleasant and healthy living climate.
The aim of this paper is to present the experimental results obtained regarding the mechanical properties of the elements of unburned clay masonry with the addition of vegetable fibers from waste and of bio-eco-innovative wool mattresses, of different thicknesses.
Following the results obtained on the 2 types of construction materials, based on clay with the addition of vegetable fibers, and sheep wool mattresses as thermal insulation material, it can be stated that they can be used successfully in construction.
MOBILITY, TRANSPORT AND SUSTAINABLE URBAN ENVIRONMENT
Authors: Kraus Michal
Published: February 2023

The paper deals with the current state and development of smart cities in the Czech Republic in the context of sustainable mobility and transport and the improvement of the quality of life inhabited by small-scale cities. Today, cities are exposed to many challenges and are looking for new efficient transport solutions that will ease existing infrastructure, improve public space, and promote sustainable modes of transport. The growth of individual car traffic has caused numerous social conflicts and environmental difficulties in recent decades. These problems are usually not affected by the size of cities and municipalities but the degree of urbanization. In all cities large, medium, and small, there is an imbalance between the need for transport and the geographical distribution of new areas of urban development. In accordance with the principles of sustainable development, smart cities must find an answer to how to combine the interests of the inhabitants of the area with security, parking, freight transport solutions, creating a public space with a preference for public transport, walking, and cycling. This contribution is supported by the project TACR ETA TL02000559 Safe and secure cities for pedestrians and senior citizens.
MULTICRITERIA ANALYSIS OF VERTICAL GREENERY SYSTEMS AND GREEN FACADES
Authors: Kraus Michal
Published: February 2023

In recent years, the whole world has been looking for the most suitable solution to deal with global warming and other environmental consequences caused mainly by anthropogenic activities. One of the potential problematic phenomena at present is urbanization, which subsequently has an impact on the enlargement of urban or suburban areas at the expense of green areas. Vertical vegetation systems are part of the blue-green sustainable infrastructure and have become increasingly popular in recent years. With the right design, the vegetation facades cool the building in the summer, warm it up in the winter and support the favorable microclimate in their immediate surroundings. Green facades can retain water at the point of impact and retain it in the substrate itself. The plants then gradually begin to regain and evaporate the water, which cools not only the building envelope but also its surroundings (they prevent the urban heat island effect). Vertical gardens with vegetation capture airborne dust, act as an acoustic absorber, and oxidize their surroundings. In addition, they protect the structure and insulation of the building, thus significantly extending the life of the facade itself. The paper aims at the characteristics of individual types of vertical green systems and the creation of a basic framework of multicriteria analysis for selecting the ideal system for a given object/construction. The multi-criteria comparative analysis evaluates the acquisition costs (investments), biodiversity, landscaping rate, landscaping intensity, maintenance requirements, improvement of the thermal comfort of the building, shape variability, and the durability of the vertical green system.

Rev. Fr. Rogelio B. Alarcon, O.P., was one of the recipients of the Ten Outstanding Young Men Award in 1972 for his innovative contribution to the system of education in the Philippines. He was the first Prior Provincial of the Dominican Province of the Philippines when the province was formed in 1972. He created and founded an educational system out of his painful experiences from the traditional system of education. Education has to bring back its noble purpose to young people who are in search of learning and not academic discrimination. Rev. Fr. Alarcon, O.P., formulated an educational system that is learner-centered even before learner-centeredness came out of literature in much recent years. His response to the prevalent problems especially of public school education in the Philippines � that is,a plague the lack of teachers, classrooms, high rate of drop-outs due to poverty, state of life and misery � is the system of non-graded, self-paced, home-study program, modular style of learning. The concept and practice of Re-entry Agenda for the Poor (REAP) an alternative to formal education, an education for all especially the indigents was founded so that the less fortunate and out of school children and youth can hold on to achieving their dreams and wish for a brighter future by finishing their education.

Published: February 2023

There is a growing optimism that the farmers' organizations can act as a potential driving force for enhancing farmers' income. India has witnessed a positive growth of producer organizations in terms of types of organization, numbers and members. The Producer Company is a special case of producer organization that is registered under Section IXA of the Companies Act, 1956. A need was felt at that time to have an independent farmersâ€™ organization which enables incorporation of producers into such an institution like the companies which will be controlled by them, having welfare and business outlook at a time while not compromising the sustainability issues. That creates the milieu for the genesis of Farmersâ€™ Producer Company (FPC) in India. The FPCs are fundamentally farmer-owned and farmer-governed micro-enterprises which can be considered as hybrids between cooperative societies and private companies. The way of participation, membership and organization is similar to that of a cooperative, while the incorporation into corporate law allows greater flexibility and professionalism in their business actions. Till date 1048 FPCs are registered in India. In this article attempt has been made to review the issues of FPC, current status and future prospects. Forecasting the growth of FPC has been done up to the year 2020 utilizing Grey Model. Emphasis has been given to critically analyse the status, prospects and potentials with future outlook of 2020 concluding with strategies and policy needs.
A comparison of fetomaternal outcome in PCEA using fentanyl, clonidine and dexmedetomidine as adjuvants with Ropivacaine in painless labor: a prospective, double blinded randomized study
Authors: Kumar A , Reena
Published: February 2023

Background: Patient controlled epidural analgesia has been associated with marked maternal satisfaction. Combination of local anesthetics with various adjuvants have been tried to ensure optimum analgesia with no or negligible fetomaternal side effects.

Aim: To compare fentanyl, clonidine or dexmedetomidine as adjuvants with ropivacaine for labor epidural analgesia (LEA) using a PCEA pump with the objective to assess fetomaternal outcome in terms of analgesic effect, success rate of vaginal delivery, complications, neonatal APGAR score and maternal satisfaction.

Materials and methods: Sixty full term laboring women received 10 ml 0.2% ropivacaine followed by continuous infusion of 0.1% ropivacaine with 2 μg/ml of either dexmedetomidine, fentanyl or clonidine respectively in Groups A, B, and C at 6 ml/hr. demand bolus setting was 2 ml with a lock out interval of 15 minutes. At full cervical dilatation another 10 ml bolus of respective solution were given. Parturients were monitored at 0, 10, 20, 30 min after giving 1st epidural bolus dose and then at 30 min interval for ongoing labor for pain relief (VAS), motor blockade (Bromage score), progress of labor (duration of 1st stage and 2nd stage), mode of delivery, fetal APGAR score (at 1 min and 5 min), vitals (HR, NIBP, RR, SpO2), overall patient satisfaction and complications. The statistical analysis was done both qualitatively (Fisher-exact test/Chi-square test) and quantitatively (one-way analysis of variance test with post-hoc intergroup comparisons using Bonferroni’s correction).

Results: Onset of pain relief was earlier in fentanyl group, however after 1 h all three groups showed comparable pain relief (P>0.05). There was a significant reduction in HR in group C and B compared to group A (P<0.001) and MAP in group C compared to groups A and B. The motor- blocking potency was slightly higher in dexmedetomidine group, however no significant motor weakness observed in any parturient. Mean demand bolus need was more in group C compared to A and B (P<0.001). There was no significant difference in mode of delivery (either SVD or cesarean) in between the groups. There was not a single case of fetal distress and most of the parturients showed satisfactory response to PCEA.

Conclusion: All three study drugs produced equipotent analgesia in combination with ropivacaine 0.1%. There was absolute pain relief without significant motor blockade or any increase in instrumentation/cesarean deliveries or any adverse fetal outcomes.

The nutritional requirements of vegetables have caused losses to small and medium-sized family farmers in terms of reduced productivity and food security in society. In this sense, the objective was to evaluate the development of okra (Abelmoschus escurentes L.) and cucumber (Cucumis sativus L.) plants, using sheep manure associated with phosphate rock and gliricídia and the quantification of the levels of N, P and K in plant structures. The experiment was conducted at the Federal Institute of Science and Technology of Roraima - Campus Novo Paraíso, in a greenhouse, using pots with a capacity of 6 L-¹, filled with soil (Neosolo) collected from the 0-20 cm layer. The experimental design was a randomized block, with treatments arranged in a 2x2 factorial, composed of two levels of gliricídia (without gliricídia (S / G) and (with gliricídia (C / G) and two levels of phosphate rock (without rock) (S / R) and (with rock (C / R), with four repetitions, being distributed in the blocks in a completely randomized way. A dose of sheep manure, corresponding to 25 t ha-1, was added to the pots. The variables determined in the study were: plant height (cm), stem thickness (mm), number of leaves, fruit diameter (mm), fruit length (cm), fruit weight (g) and the contents of N, P and K in the plant and in the fruits The results found for the different treatments showed no differences It was observed that the standardization of the fertility of the pots directly interfered in the statistical results, this way, the farmers can renounce the use of the leaf of the gliricídia and of the rock phosphate, as long as he has sheep manure available.

The aim of the study was to carry out an epidemiological characterization of drug use in the interior of Brazil and to identify factors associated with it. For this purpose, 1806 high school students from 10 municipalities in the state of Goiás participated of the survey. The results indicate the beginning of the use of alcohol and illicit drugs in the early years of adolescence, influenced mainly by friends and family. There was a greater consumption of drugs, alcohol and tobacco in relation to illicit substances. Protective factors such as adherence to a religion proved to be relative and family situations that involved violence and significant losses were revealed as risk factors. Finally, the epidemiological data collected on drug use, indicate the urgent need to plan and implement a public educational policy for adolescents that is broad enough to address the various facets of legal and illegal drugs.

Food and nutritional education proposal for sustainability
Authors: Cavalcante Antonio Nilson Alves , Freitas Roberta Michele Barbosa , Paula Paulo Carvalho de
Published: February 2023

Abstract Historical events related to the Industrial Revolution gave rise to various questions about sustainability so the socio-environmental crisis we are currently facing indicates an urgent need to strategically position ourselves in the face of environmental and climate shocks developed from the development of human activities that, triggered in this process, directly and profoundly affect ecosystems. Such a context makes sustainability something to be taken as a priority in the development of society, moving away from a characterization of business profitability, to the point of referring to care for the planet, through isonomic attention to economic, social, and environmental aspects, whose awareness permeates the local and planetary socio-environmental scope, to mobilize governments, companies, and civil society because of facing the climatic and ecological crises, which gains greater impetus from educational proposals that take the environment as the focus of their concerns. From then on, our goal is to raise some contributions from Food and Nutrition Education (EAN), as a resource conducive to approaching sustainability in the school environment, through interventions such as exploring preparations and experiences with natural foods, cultivation for consumption knowledge about sustainable food, etc., be included in the educational curriculum as a cross-cutting theme, understanding that, more than ever, an attitude is needed to minimize the impacts that negatively affect ecosystems. Thus, our study is carried out through a multidisciplinary integrative literature review, aimed at condensing a series of results offered by studies in different areas, such as Education, Nutrition, and Ecology, which allows articulating the theme of EAN as a means of contributing to students' awareness of issues related to sustainability and food aspects, and we can point out, as a result, several aspects concerning new considerations and behaviors regarding the planet itself.

The present study adopted the objective of describing the perception of students of the bachelor's degree course in Libras Letters of the Federal University of Ceará regarding the use of active methodologies in the mediation of bilingual and bicultural education. This is a Survey, a qualitative descriptive study, conducted from September 10 to 30, 2020, with 24 students. The inclusion criterion adopted the condition of having experienced the methodologies active in learning mediation in the period 2018.1 to 2019.2, in at least one of the five disciplines defined. The sampling of 24 respondents was intentional in the universe of 64 students who were distributed in 6 (25%) deaf and 18 (75%) listeners. A mixed digital questionnaire was applied through the Google Forms platform, containing 10 closed and 2 open questions, all in Portuguese and Libras, for each of the seven active methodologies techniques. The results point to the effectiveness of techniques in the teaching and learning process of bilingual classes, especially in the consolidation of student autonomy and the development of criticality. Research is suggested to evaluate, in the same way, the student's perception of the use of Active Methodologies as learning assessment strategies.

Published: February 2023

This work approaches school architecture from the perspective of memory and the history of education and refers to the buildings of school groups in Belém that originated in the First Republic of Pará. In that period, the school space became a symbol and object of construction of the new regime and materialized as ideas and educational policies of the republicans, being an important source, full of information about the society of the time. Our objective is to analyze the architectural characteristics of these buildings from documentary research based on a theoretical framework in Nora (1997), Coelho (2008), Bogéa (2009), and Lobato (2014 and Bôas) (2015). In the methodological scope, we developed demos in addition to studies on the buildings survey and literature review, or that portrayed the discussion of the concepts of memory and primary period, then we did the primary research partial analysis. Visits to recording and analysis institutions will also be presented as preserved architectural features. The school buildings under study materialized positivism and hygienist in architectural features and had the predominant aesthetic of eclectic style, with emphasis on neoclassicism and art nouveau, to praise Public Instruction as a condition for civility. As for the preservation of the buildings, only the buildings of the Barão do Rio Branco Floriano Peixoto school groups maintain the restoration of the original characteristics of their construction. The school groups José Veríssimo, Rui Barbosa, Wenceslau Braz, and Benjamin Constant received several renovations that completely modified the facade and lost the meanings subliminally imbued by the republicans and, consequently, part of the memory and history of education was lost with the de-characterization of architecture.

Authors: Modesto Ákilas Girão , Mainier Fernando Benedicto
Published: February 2023

Corrosion is one of the main factors responsible for losses in companies subject to aggressive atmospheric environments, as is the case with industries in the oil and gas area, close to coastal regions. This work carried out a comparison between two surface treatment techniques for industrial painting in order to find the most resistant technique to the environment in which the equipment was inserted. An experiment, using the techniques of mechanical treatment with needle gun and wet abrasive blasting, was carried out in an industrial oil refining unit. The study was developed through the application of the two techniques in industrial valves that were in operational conditions and available in a treatment cabin. The results showed, right after treatment and before paint application, that the surface worked with wet abrasive blasting was cleaner and free of encrusted oxides than the surface treated with a needle gun. The results were also analyzed during the exposure of the valves, over time, after the application of the paint. It was noticed, in a period of sixteen months, that there was greater durability, in relation to the appearance of corrosion points, on the surface treated with wet abrasive blasting.

No presente artigo mostramos que um detector perfeito de defeitos P (que suspeita todos os processos que falharam se e somente os mesmos falharam) pode ser implementado num sistema mais fraco que o sistema distribuído síncrono (contrariando uma crença estabelecida). Nesse sentido, introduzimos o sistema síncrono particionado (Spa) que é estritamente mais fraco que o sistema síncrono (em Spa não é sempre possível implementar ações síncronas globais como sincronização interna de relógios). Através da propriedade que definimos como sincronia particionada forte, mostramos como implementar P em Spa. Melhor ainda, mostramos que mesmo que Sincronia Particionada Forte não possa ser garantida, podemos ainda assim tirar proveito das partições síncronas existentes para melhorar a robustez das aplicações de tolerância da falhas, através de um detector parcialmente perfeito, denominado por nós de xP. As propriedades e algoritmos necessários para implementar P e xP são introduzidos no artigo, assim como as provas de correção relacionadas.

As tecnologias disponíveis para o desenvolvimento sistemas distribuídos não atendem perfeitamente à classe de sistemas complexos e que precisa manter diversas conexões abertas simultaneamente em um nó. A comunicação assíncrona de objetos distribuídos facilita a construção destes sistemas. Neste trabalho, definimos quatro requisitos para uma semântica de falhas consistente para este tipo de comunicação. Além disso, projetamos e verificamos formalmente um Protocolo de Conexão que atende a esses requisitos. Por fim, descrevemos a arquitetura de uma plataforma para objetos distribuídos assíncrona que usa este Protocolo de Conexão.
Deriving a Fault Resilience Metric for Real-Time Systems
Authors: Nascimento Flávia Maristela , Lima George , Lima Verônica Cadena
Published: February 2023

Most real-time systems are required to comply with strict time and logical requirements even in the presence of faults. Although scheduling policies and schedulability analyses have been extended to deal with fault tolerance, not much attention has been given to measuring the fault resilience of such systems. Usually, worst-case error patterns are artificially assumed and system correctness is checked. However, such patterns do not represent the capacity of the system to tolerate faults, nor consider the overall system behavior in the presence of faults. In this paper we define a fault resilience metric and present a simulation-based analysis. Then we show how simulation results can be statistically analyzed.

Esquemas de gerenciamento de chaves baseados em cadeias de certificados mostram-se como os melhores para MANETs. O principal esquema baseado em cadeias de certificados é o Self-Organized Public Key Management System (PGP-Like). Entretanto, ele é completamente vulnerável a ataques de personificação. De maneira a reduzir tal vulnerabilidade, este artigo introduz um novo esquema de gerenciamento de chaves para MANETs, o Virtual Key Management System (VKM). O VKM faz uso de uma estrutura virtual para indicar a confiança entre os nós e a formação das cadeias de certificados. O VKM é um esquema flexível podendo se comportar de uma maneira restrita, capaz de suportar ataques de personificação até um certo nível, ou pode se comportar de forma similar ao PGP-Like, mudando um simples parâmetro. Portanto, o VKM pode suprir a necessidade de qualquer usuário sendo capaz de alternar o seu comportamento dinamicamente, sem qualquer reinicialização ou reconfiguração.

Background: Since EGFR inhibitors show a limited therapeutic effect on Glioblastoma multiforme patients, the EGFR/MAPK/STAT5/FN14 signaling pathway becomes vulnerable to the invasive GBM cell population and may be a suitable target for the treatment of GBM. Nanocurcumin consumption and exercise training are probably effective interventions in this signaling pathway. Objectives: This study aimed to investigate the simultaneous effects of exercises training and Nanocurcumin consumption on the EGFR/MAPK/STAT5/FN14/FN14 pathway in the tumor tissue of GBM model rats. Methods: In this study, 40 male Wistar rats were randomly assigned to five groups: (1) control (CON), (2) glioblastoma multiform (GBM), (3) glioblastoma multiform+concurrent training (GBM+CT), (4) glioblastoma multiform+nanocurcumin (GBM+NC), and (5) glioblastoma multiform+nanocurcumin+concurrent training (GBM+NC+CT) groups. The target groups performed aerobic training (20 - 35 minutes at 18 m/min) along with resistance training (climbing the ladder in three sets repeated four times) and received Nanocurcumin at the rate of 100 mg.kg-1.day-1 for four weeks. Gene expression was measured by real-time PCR. Two-way analysis of variance was used for analyzing data. Results: According to our study results, concurrent training significantly reduced the expressions of EGFR, MAPK, STAT5, and Fn14, mRNA compared with GBM group (P < 0.05). Furthermore, nanocurcumin significantly reduced the expressions of EGFR, MAPK, as well as Fn14, mRNA compared with GBM group (P < 0.05). Nanocurcumin+Concurrent training decreased the expressions of EGFR, MAPK, STAT5 as well as Fn14, and mRNA compared with the GBM group (P < 0.05). A significant reduction was recorded for all mRNA expression levels in the GBM+NC+CT group compared with those in the GBM+NC group (P < 0.05). Conclusions: In sum, combined exercises and nano curcumin consumption may have been adopted as a non-pharmacological strategy to modulate the expression of EGFR/MAPK/STAT5/FN14 genes in tumor tissue of glioblastoma multiform.
Promoting engineering students’ learning with mathematical modelling projects

Mathematics constitutes a key component in engineering education. Engineering students are traditionally offered a number of mathematics courses which provide the knowledge needed at the workplace. Unfortunately, many students perceive mathematics as a discipline that teaches mostly procedures not relevant to their future careers and often view it as one of the main obstacles on their way to an engineering degree. In this paper, we discuss how introducing university students in a standard Differential Equations course to mathematical modelling (MM), a powerful strategy for solving real-life problems, contributes to the development of their mathematical competencies, motivates their interest to mathematics, promotes the use of advanced mathematical thinking, methods of applied mathematics, and digital computational tools.
Trolley Problem Applied

Even a dog can tell if he was tripped over or kicked. Would entrepreneurs know? To slow down the progress of the SARS-CoV-2 pandemic, many states have taken restrictive measures, including the closing of private businesses. Are entrepreneurs therefore entitled to compensation? The answer is not obvious. In this paper, I suggest a solution which follows from a si mple test inspired by the famous trolley dilemma, asking whether the state used entrepreneurs as instruments (means) to slow down the pandemic. I argue that entrepreneurs were not “used” that way, which is why they possess no moral claim to compensation for the harm caused by the closure. However, I do argue for at least a moral claim of theirs to satisfaction. For the possible disruption of their relationship with other citizens, rather than for the monetary damage they were forced to bear.

Making product Hand sanitizer and implementing a clean and healthy lifestyle were an effort to break the chain of the spread of Covid-19. The making of hand sanitizer made from alcohol has been recognized as being able to kill viruses. For example Alcohol, H2O2 (Hydrogen Peroxide), Glycerol / Glycerin, and Aquades / Distilled Water. This new normal situation must be balanced with a healthy lifestyle. The aim of this assistance was to conduct training in making hand sanitizer in order to improve the economy and the application of healthy living during the Covid-19 pandemic. The researchers used ABCD (Asset Community Based Development) method, with stages; Discovery, Dream, Design, Define, and Destiny. Through this method, the discovery of assets and potentials leads to the provision of activities in the form of training and mentoring to produce hand sanitizer product. This economic assistance activity has an impact on the availability of hand sanitizer that were quite used by residents, and in marketing using online media which has a significant impact on residents.

The aim of this article was to describe how the principles, objectives, the function and approach of supervision, as well as how the head of madrasah carries out the planning, implementation and follow-up of academic supervision at madrasah. The researchers used literature review. The step was to trace the printed and electronic references regarding the supervision of madrasah principals in general, then narrow it down to the sub-focus of the discussion, namely the academic supervision of madrasah principals. Once deemed sufficient, the authors describe it systematically. The findings of this study showed that academic supervision was an effort to help teachers develop their abilities in achieving learning goals. The essence of academic supervision was not any assessing the performance of teachers in managing the learning process, but helping teachers  to develop their professional abilities. Academic supervision that must be carried out by the principal of madrasah includes: planning an academic supervision program, carrying out academic supervision, following up on the results of academic supervision aimed at increasing the professionalism of teachers as professional educators.
