Considerações sobre a análise de jornais como fontes históricas, na sua perspectiva sincrônica e diacrônica
Authors: Barros José D'Assunção
Published: December 2022

O artigo aborda o uso dos jornais como fontes históricas, com especial atenção ao problema de que os jornais a serem analisados pelos historiadores precisam ser vistos como inseridos em uma rede de concorrência formada por outros jornais que disputam o mesmo público-leitor ou diferentes tipos de público. A exemplificação incide sobre dois momentos na história da imprensa brasileira, relacionados à cidade do Rio de Janeiro: a Primeira República, na qual os jornais já se achavam inseridos em uma rede mercadológica capitalista, e o Brasil do princípio do século XIX, na qual os jornais tinham principalmente um propósito político e lidavam ainda com pequenas tiragens, sendo habitualmente comandadas por um pequeno grupo de pessoas. O propósito do artigo, além da reflexão metodológica inicial, é discutir a importância deste aspecto – a inserção dos jornais em uma rede – e o exemplo proposto é apenas um caminho para abordar o problema.
Entre o cristal e o fluxo: fontes historiográficas e as articulações têmporo-espaciais
Authors: Genovez Patrícia Falco
Published: December 2022

Esta “nota” tem como pano de fundo uma investigação de pós-doutoramento onde são levantadas algumas questões sobre a História e os seus recursos de investigação. Algumas dessas questões estão profundamente relacionadas ao fato de essa disciplina desconsiderar uma abordagem crítica de seu próprio fazer. Daí surgiu uma espécie de enrijecimento do ofício do historiador, não permitindo diálogo mais profundo com outras áreas do conhecimento e a apropriação de novos conceitos de tempo. A presente reflexão surge com a possibilidade de uma leitura historiográfica das fontes tendo como ponto de apoio a interação têmporo-espacial. Tal possibilidade é um desafio para a historiografia no sentido de tratar as fontes como um fluxo contínuo, ou seja, como uma narrativa.

Published: December 2022

A Campanha dos Bancos no Canadá foi um esforço conjunto de diversos movimentos sociais, ONGs e igrejas que buscavam denunciar os empréstimos e investimentos feitos por bancos canadenses ao governo do Apartheid. A ação militante da sociedade civil canadense se junta a uma rede transnacional de apoio ao movimento antiapartheid. Reino Unido, Estados Unidos e países da comunidade europeia compõem parte dessa mobilização. O presente artigo irá analisar a Campanha dos Bancos canadense entre os anos 70 e 80, compreendendo sua atividade como pertencente a uma rede transnacional de advocacia e agindo como um ponto de pressão internacional. A investigação terá por base o uso de fontes documentais, com a análise se dando sobre as publicações da revista TCLSAC Reports, do coletivo militante Toronto Committee for the Liberation of Southern Africa. A Campanha dos Bancos foi explorada através de um recorte de artigos da revista, destacando as relações locais, nacionais e globais da ação política contenciosa do grupo. Através da análise se destacou a capacidade de articulação deste coletivo com elementos em diferentes escalas e com um alto fluxo de informações.

As conferências internacionais de mulheres entraram em evidência nas décadas de 1960 e 1970. Este artigo tem como objetivo central a investigação do campo político internacional no qual as mulheres integrantes da Frente de Libertação de Moçambique estavam ativamente inseridas. Ao analisarmos a publicação “The Mozambican Woman in the Revolution”(1974) produzida pela organização Liberation Support Movement do Canadá parte do documento se dedicou a atuação das mulheres da FRELIMO durante a 10ª Conferência das Mulheres Africanas (AAWC), de 1972. Esse documento revela não apenas a forma de atuação das mulheres, mas como elas formaram uma ampla e complexa rede política internacional durante a Guerra Fria.
TRAJETÓRIA DO PRONAF
Authors: Lopes Indaia Dias
Published: December 2022

Resumo: O objetivo deste estudo é descrever a trajetória histórica do Programa Nacional de Fortalecimento da Agricultura Familiar (Pronaf) e apresentar dados sobre este Programa no estado do Rio Grande do Sul (RS) a partir do discurso de diferentes atores sociais regionais envolvidos com essa política pública. O Pronaf passou por diversas reformulações, porém, desde sua implementação observou-se concentração dos recursos na região Sul do país. Os atores sociais envolvidos compreendem o Pronaf como um Programa que beneficia o agricultor familiar e contribui para a permanência do mesmo no meio rural, porém, são necessárias políticas e programas complementares para atender as necessidades dos agricultores. O modelo de desenvolvimento que está sendo realizado no Rio Grande do Sul pelo Pronaf pode ser entendido como aquilo que a literatura especializada define como botton up, ou seja, de baixo para cima, modelo este que contribui para o desenvolvimento sustentável do crédito rural no Estado.

The winter of 2022 approaches with the need to finalize our plans for next year. This is urgent for the 2023 Meeting of the Padua Days of Muscle and Mobility Medicine (Pdm3) to be held March 29th to April 1st, 2023 at the Hotel Petrarca in the Thermae of Euganean Hills (Padua), Italy. A preliminary Pdm3 Program is almost ready with sessions, organzers and keynote speakers, but ther is still rooms for many interesting and interested young speakers. Some of the Pdm3 sessions dedicated to molecular and cellular myology are organized by old Pdm3 Friends, but there will also be interesting new entries, including those for Rehabilitation Sessions. No doubt that 2023 Pdm3 will attract old friends, but topics of a few sessions are at the frontiers of Translational Myology and new entries are most warmly acknowledged. This is true for both basic myology research, which include beside traditional MiRNA the new entry of the LNC-RNA and the “dark side of the genome”. As to rehabilitation topics, beside the old friends of the “LBI workshop on muscle rehabilitation - from mouse to elderly”, new entries are sessions on Muscle Fascia, Muscle Rehabilitation in Dentistry (that will organize also a Practical Course) and the session on “European Medical Thermalism and FEMTEC” that will also offer a practical Course. We hope that by January 20th, 2023 many old and new friends will send their abstracts to fill an half-empty program and then by May 1st, 2023 they submit Communications to EJTM that deserve them to increase the 2023 EJTM Impact Factor.

Published: December 2022

Physico-chemical properties of obizi river in awka south local government area of anambra state were analyzed for its pollution level and determined if it will be fit for domestic purposes. It is significant for cooking, drinking, fishing, recreational and other uses. It flows via a channel that may be contaminated by industrial, agricultural, and other anthropogenic activities, limiting its normal uses for cooking, drinking, fishing, recreational and other uses. The parameters analyzed includes temperature (°C), pH, turbidity (NTUb), conductivity μs/cm, resistivity mg/l, chloride mg/l. Temperature(°C), pH, turbidity (NTUb) resistivity mg/l and conductivity μs/cm was measured in-situ using mercury thermometer with a range of 100C -350C, pH meter (HANNA H1991002), turbidimeter (Hl 88703, WAGTECH), conductivity and resistivity multi-meter (HI 991300, Hanna Instruments, Romania) and chloride was determined by titration. The results of the analysis were equivalence with world health organization (WHO) limit for domestic drinking water and other purposes. From the results obtained, it showed that all the parameters analyzed were above WHO permissible limit except resistivity and chloride which is within the world health organization (WHO) limit for domestic drinking water. As much, it is not recommended for human consumption and is recommended that the state government put in place a treatment plant which can be used to treat the obizi river water before being used by the community that depends solely on it for domestic purposes.

Authors: Edu C. N. , Oluka S. I.
Published: December 2022

Field experiment research was conducted to determine the effects of Sawah Technology on NERICA rice production from April to December 2020 during the rainy season at two different locations, namely, Ishieke and Imeoha Nkerefi in Ebonyi State and Enugu State respectively, both in the south-east of Nigeria. Six NERICA rice varieties: Sipi692033, WITA 4, NERICA 34, NERICA 1, NERICA 7 and NERICA 19 were used for the study on two Sawah fields and two non-Sawah fields measured 0.3ha each. Research data, namely: height, width, panicle length, grain number, and grain weight were collected starting from nursery to maturity of the rice. The study revealed that Sipi692033 has the highest yield of 5 tons/ha under Sawah Technology condition. The findings of the study show that the panicle length, grain number per panicle, weight of 1000 grains, and yield (ton/ha) were higher by 55.56 %, 50.00 %, 39.41 %, and 87.50 % respectively in the Sawah field relative to the non-Sawah field. The study concludes that Sawah technology enhances rice yield by at least 50 per cent.

Authors: Ekemube R. A , Atta A. T , Okogbule-Wonodi A.
Published: December 2022

Fuel consumption model for predicting tractor fuel consumption per working area for harrowing operation has been developed using dimensional analysis. Generalized reduced gradient method of Excel solver was adopted for the establishment of the model’s constant. The model was validated by simulating the experimental results into the equation and coefficient determination (r2). Graphical comparison, root mean square error, and paired t-test were also use to validate. The field experiment was carried out at Rivers Institute of Agricultural Research and Training Farm in Rivers State University, Port Harcourt. The group balanced block design was adopted. The design consisted of 9 experimental treatments with three replicates. The experimental fuel consumption per working area was determined by quantity of fuel used per working area with the aid of fuel flow meter. The field test parameters were measured accordingly with their specific standard procedures. The field test parameters including bulk density, tractor forward speed, harrowing depth, and cone index were simulated with fuel consumption to obtain the constants in the prediction model. The developed model showed good agreement between measured and predicted results with high coefficient of determination and low root mean square error. The paired t-test results showed no significant difference at 95 and 99 % confidence levels. Thus, suggested that the model could be used for predicting tractor fuel consumption for harrowing operation.

Published: December 2022

An 8-litre capacity roselle calyx extractor was developed with Arduino based temperature controls ranging from 30 to 100⁰C. Performance evaluation conducted on the extractor showed that efficiency of the extractor increased as the weight of the calyces decreased at constant mass of water which ranged from 55% to 89%. The effect of extraction time (5, 10 and 15 minutes), process temperature (30, 50, 75 and 100⁰C) and calyx-water mass ratio (1:50, 1:20 and 1:10) on the pH, density and colour of the extract was determined. The pH ranged from 2.4 to 2.9 and density was from 1.02 to 1.05gcm-3. Statistical analysis conducted showed that temperature and calyx-water mass ratio has a linear significant effect (p<0.001) on all the responses while time had a linear significant effect (p<0.001) on all responses except density. Time and temperature had interaction significant effect (p<0.01) on pH, while temperature and calyx-water ratio had interaction significant effect (p<0.01) on the density of the extract. Calyx-water ratio had a quadratic significant effect (p<0.001) on the pH and colour of the extract. The contour plots presented the interactions between the factors and their responses. This study demonstrated that roselle calyces extract can be produced more efficiently than practices currently available and also that processing conditions are very important in the quality of extracts produced.

Published: December 2022

Efforts to replace the lead-based perovskite have gain significant improvements in the last decade. Lead free double halide perovskite are being considered to replace the toxic lead-based perovskite materials for solar cell applications. Density functional theory (DFT) and linear response time-dependent density functional theory (TDDFT) are used in this study to simulate and investigate the effect of vacancy in the Indium (In) site of leadfree double halide perovskite A2BB′X6 (A = Cs; B = In, B′ = Sb; X = Cl) on the structural, electronic, and optical properties for possible solar cell application. On the structural properties, the total bond length of the material Cs2InSbCl6 was found to be 30.3848 Å and the creation of the indium vacancy raises the value to 30.594 Å. The bulk modulus of Cs2InSbCl6 was calculated to be 28.44 Gpa and 26.22 Gpa for Cs2In-xSbCl6. The calculated band structure for Cs2InSbCl6 reveals semiconducting behavior with a direct energy band gap of 0.99 eV along 𝛤 point symmetry while the created indium vacancy band structure reveals metallic behavior with an overlap of electronic states along the Γ - W – Γ symmetry. The result of the optical properties calculations shows that the material Cs2InSbCl6 has higher absorption coefficient, low refractive index, low reflectivity and higher conductivity when compared to the created indium vacancy material.
Africa Integrated Maritime Policy, blue growth and a new ocean governance: case studies from the Atlantic and the Indian Ocean
Authors: Guerreiro José
Published: December 2022

Integrated maritime and blue economy policies are changing ocean governance by introducing new policy drivers, reshaping institutional frameworks, as well as demanding new management instruments (e.g., Maritime Spatial Planning (MSP)). This started in 2007 though the European Union Integrated Maritime Policy approach, and in 2009 the Africa Union initiated a similar process, leading both to the Africa integrated maritime strategy as well as a blue economy strategy. Several countries, particularly in sub-Saharan Africa, began to look to blue economy as a booster to socioeconomic welfare and initiated the development of national strategies, together with the necessary adaptation of institutional and legal networks. Case studies address those processes at the transition from the Atlantic to the Indian Oceans, focusing on Angola, Namibia, South Africa, Tanzania and Kenya in the Southern African Development Community (SADC) region, as well as several African Small Islands Developing States (SIDS), particularly Cape Verde, S. Tomé and Príncipe, Seychelles, Madagascar and Mauritius. Findings show that all countries covered in the case studies are developing national ocean and/or blue economy strategies and adapting their governmental, institutional, and legal frameworks, although there is a deeper political impact in SIDS. Overall, these new policy drivers are leading to a new model of ocean governance by addressing integrated maritime policies and blue growth strategies, as well as introducing MSP as a new EEZ governance tool.
Structural complexity of seagrass and environmental variables as a determinant of fish larvae assemblages in tropical coastal waters: Implications for seagrass management and conservation
Authors: Malesa Fadhili M. , Tarimo Barnabas , Kyewalyanga Serapio , Rushingisha George
Published: December 2022

Anthropogenic activities including climate change affect the development of structural complexity in seagrass and the state of environmental variables. It remains unclear whether these variables, alone or in combination, have an important influence on fish larvae assemblages. This study examined the influence of the structural complexity of seagrass meadows and various environmental variables on fish larvae assemblages in tropical coastal waters of Tanga, Tanzania. The study was conducted in four Thalassia hemprichii dominated seagrass meadows from June 2019 to January 2021. Multiple regression analysis indicated that the structural complexity of seagrass (canopy height, seagrass cover, and shoot density) and environmental variables (dissolved oxygen, temperature and salinity) were the foremost predictors for fish larvae assemblages; abundance and richness (R2 = 0.75, p = 0.0185, R2 = 0.54, p = 0.0396, respectively). Based on these findings, the structural complexity of seagrass and environmental variables are both important determinants of fish larvae assemblages in tropical coastal waters. The findings suggest that reducing anthropogenic activities that affect the development of structural complexity of seagrass and negatively impact environmental variables in seagrass meadows through more effective governance would result in increased production of fish larvae in meadows and, as a result, increased fish recruitment in tropical coastal waters.
Small pelagic marine fisheries for food sovereignty? The case of the dagaa fishery at three coastal sites in Tanzania
Authors: Katikiro Robert E. , Mahenge Jairos
Published: December 2022

To implement effective ocean governance, development of policies and management strategies needs to incorporate input from communities that will be impacted by the decisions. People engaging in small-scale fisheries and aquaculture mobilize themselves in anticipation of various challenges, for example, food sovereignty. Food sovereignty is the right for people to access healthy and culturally appropriate food that is produced through ecologically sound and sustainable methods. Little attention has been paid to documenting and understanding the struggles and efforts of small-scale fishers to ensure their own food sovereignty. In the Western Indian Ocean region, and Tanzania in particular, there has been a limited number of initiatives among coastal fishers that seek to transform food systems. To better understand these initiatives, this study was designed to examine collective actions undertaken in pursuit of food sovereignty among small pelagic fishers at three landing sites on the coast of Tanzania. Collection of primary data involved a survey of 206 individuals, 25 key informant interviews, 3 focus group discussions and participant observation. Secondary data was also collected from official fisheries records and published materials to supplement the primary data. The study revealed limited current capacity of the small pelagic fisheries to satisfy local demand of fifish for food security and sovereignty purposes due to increased fish trade supplying markets beyond the study sites. The prospects of satisfying an increasing fish demand from existing production systems are limited. Small pelagic fisheries need to be linked to the global food system through appropriate mechanisms to allow them to contribute meaningfully to food security and sovereignty.
Genotoxic Effects of Rice-Agrochemicals on Channa punctatus (Bloch) and Cyprinus carpio (Linnaeus) Using Micronucleus Assay and Alkaline Single Cell Gel Electrophoresis
Authors: Kaur M. , Bhatnagar A. , Dhillon O. , Yadav A. S.
Published: December 2022

Rice-cum-fish culture is a cost-effective practice for marginal farmers but the major constraint is the indiscriminate use of agrochemicals. Present work was designed to assess the genotoxic effects of rice agrochemicals in Channa punctatus (Experiment 1 CP1 to CP3) and Cyprinus carpio (Experiment 2 CC1 to CC3); using micronucleus, chromosome aberration, and single cell gel electrophoresis/Comet assay. Two experiments with three treatments (CP1/CC1: without pesticide; CP2/CC2: recommended doses; CP3/CC3: farmers’ dose) were maintained in triplicates. The presence of tail DNA and micronuclei depicted significant DNA damage (P<0.05) in all the treated fish. The mean percent frequency of MN showed significant (P<0.05) differences with respect to the initial. The chromosomal aberrations and mean frequencies of tail DNA (%) were significantly abundant in CP3 and CC3 indicating high a genotoxic effect. Keeping in view the low genotoxic effects, treatment of CP2 and CC2 with recommended doses of pesticides may be disseminated to farmers.

The designed machine was tested at three levels of cylindrical sieve angle 4, 7, and 10 degree and three levels of flat sieve speed 0.62, 0.88, and 1.08 m s-1. The evaluation criteria included machine productivity (MP), cleaning efficiency (CE), percentage of seed losses (Psl), specific consumed energy (Ec), and germination percentage (Gp). The results showed that the maximum values of MP and CE were 680.14 kg h-1 and 99.85 % respectively. While the minimum value of Ec was 5.88 kW h ton-1. These values were achieved at cylindrical sieve slope angle 7 degree and flat sieve speed 0.88 m s-1. Under these working conditions, the values of MP, Ec and CE were 680.14 kg h-1, 5.88 kWh ton-1, and 99.85%, respectively. Thus, the designed machine can be used with enough confidence to clean the canola seeds at cylindrical sieve slope angle 7 degree and flat sieve speed 0.88 m s-1.

Published: December 2022

Watermelon is mostly eaten in fresh form due to its high moisture content which is responsible for its deterioration within a short time. Foam-mat drying of watermelon was carried out using a mechanical dryer. In the foam mat drying experiments, 10% egg albumen and 2% carboxyl methylcellulose were used as the foaming agent and stabilizing agent, respectively. Thin layer drying was carried out in the mechanical dryer under temperatures of 60 and 70C. Some nutritional qualities and chemical compositions of the watermelon were determined before and after drying. The result of the phytochemical properties revealed that the watermelon flakes have a high value of flavonoid content of 1.18±0.02 and 1.09±0.00 mg 100 g-1 with low terpenoid contents of 0.10±0.00 and 0.11±0.00 mg 100 g-1 for the sample dried using 60 and 70C respectively. High ferric ion reducing antioxidant power (FRAP) value of 38.73±0.90 and 41.25±0.90 mg g-1 with low lycopene value of 0.312±0.00 and 0.323±0.01 mg g-1 was observed for the antioxidant properties of watermelon dried at 60 and 70⁰C. The vitamin content shows that the flakes are highly rich in vitamin C (46.26±0.03 and 47.35±0.02 mg g-1 for 60 and 70C, respectively) and had a low vitamin B1 content (0.15±0.01 and 0.13±0.00 mg g-1 for drying temperature of 60 and 70C, respectively). Therefore, the results of the foam-dried watermelon flakes showed that the qualities of the watermelon were preserved during drying and safe for consumption.

Published: December 2022

The academic period is a very significant aspect of an individual’s development. Although it is constantly observed that students fail to achieve their full potential. Procrastination or the act of delaying tasks might be a major reason in this aspect. The present study has focused upon the relationship between academic procrastination and resilience. Resilience is the ability to bounce back from difficulties and adapt to such situations. The Academic Procrastination Scale Short Form (APS - SF) and the Brief Resilience Scale (BRS) was used in order to measure the procrastination and
resilience among students, respectively. The measures were administered among 80 undergraduate college students selected through convenient sampling method. The data was analysed with Spearman’s correlation method. The results show a significant negative correlation between academic procrastination and resilience. Hence it is inferred that if students can develop high resilience they may procrastinate much less in their academic activities. The limitations and suggestions for further studies are discussed.

Conceptual Aspects on Mobile Ad-Hoc Network System
Authors: Shreya Mane
Published: December 2022

A mobile ad hoc network is made up of mobile wireless hosts. When hosts move, the
routes change, necessitating the need for a system to find new routes. A crucial aspect of the development of wireless networks is ad-hoc networking. Ad-hoc networks often consist of identical nodes that connect with one another via wireless links without the use of a centralized controller. Ad-hoc wireless networks carry over the standard issues with wireless and mobile communications, like bandwidth optimization, battery management, and improvement of transmission quality. Due to its self-upkeep and self-configuration characteristics or behavior, mobile ad hoc networks (MANET) have achieved great success and attention. Routing attacks are used to quickly alter the
network topology of MANETs based on wired and wireless networks. Therefore, securing this network without infrastructure is a big problem. In recent years, experts from all over the worldhave paid particular attention to research on improving the performance of mobile ad-hoc networks (MANETs). Routing methods are especially crucial in a dynamic network environment like MANET for enhancing overall network performance. In addition to discussing the technical difficulties that protocol designers and network engineers must overcome, this paper offers insight into the possible applications of ad hoc networks. Routing, service and resource discovery, Internet access, billing, and security are some of these difficulties.

Este trabajo de investigación reconceptualiza el genocidio de los pueblos indígenas desenredando sus dimensiones culturales. Las operaciones extractivas y similares deterioran gradualmente las tierras y el medio ambiente, ejerciendo severos impactos en los derechos territoriales, eventualmente en su aniquilación física y cultural. El artículo aborda el crimen de genocidio tanto en su dimensión física como cultural, exigiendo su integración en el Derecho Internacional de los Derechos Humanos (DIDH) y el derecho penal. Investigaciones etnográficas recientes en Ecuador demuestran como los pueblos indígenas están gradualmente expuestos a políticas genocidas a pesar de los sólidos marcos legales. Dichos derechos se materializan en forma de consulta previa, derechos territoriales, prohibición de reubicación forzosa y mantenimiento de procedimientos organizativos y de toma de decisiones.
Studying humour from a Conversation Analytic perspective
Authors: Çopur Nimet , Atar Cihat ,   Recep Tayyip Erdopan University,   Sakarya University
Published: December 2022

Humour is a complex and dynamic phenomenon prevalent in social interaction in various settings, such as mundane talk and institutional contexts. It has been a focus of interest in social interaction research for decades. To date, scholars have sought to gain insights regarding what counts as humorous and why we find certain utterances funny (e.g., Carroll, 2014; Bell & Pomerantz, 2016). As such, scholars from various fields ranging from philosophy, sociology, psychology, pragmatics, and linguistics, to name a few, have adopted different approaches in the examination of humour. One of the new perspectives that offers unique insights into humour scholarship is Conversation Analysis (CA) methodology. CA is a method and a research field in itself deriving from ethnomethodology, and it provides valuable opportunities for researchers to investigate humour in interaction. Thus, the main aim of this study is to present Conversation Analysis as a candidate methodology to be used for analysing humour in interaction. It also provides a critical discussion of how CA approaches ‘humour’.

When “school in the classroom” became “school at home”, both teachers and learners found themselves on an unexplored territory. We hypothesized that the change came along with a set of challenges that were partly similar, partly different around the world. Challenges were met with either timid or firm immediate efforts of applying approaches, strategies and techniques that could make teaching an effective process, even under the new circumstances. The aims of the paper are to provide insights into the challenges online teaching faced during the Covid-19 pandemic in countries around the world, to identify the (applied or suggested) solutions for diverse challenges and similarities or differences between challenges/solutions. In our research, we used a qualitative method based on a purposeful sampling technique and collected data from the research work of scholars in countries from the six inhabited continents. Results confirmed our hypotheses. Although we had glimpses of the world online teaching process situation under unprecedented conditions, we could draw some general conclusions. The most important one was that countries tried their best to make teaching as effective as possible and offer students the opportunity to learn, although the approach was a difficult one, for both teachers and students, with repercussions (that were not necessarily positive) on the learning process. These repercussions could be noticed in each individual country, when returning to face-to-face teaching, and they now represent the hot topic of research all around the world.

The energy transition basically implies a phased and significant reduction in the use of fossil fuels, until the final cessation of use in the near future. Renewable energy sources and alternative fuels are an increasingly important part of the energy transition. At the same time, it is necessary that energy systems increase energy efficiency and environmental acceptability. In this regard, great efforts are being made to expand the portfolio of primary fuels in existing large energy systems, e.g. thermal power plants. Therefore, today in large boilers, in order to reduce NOx emission, staged air supply for combustion is inevitably used as the primary measure in the furnace (air staging). In addition to the previous measure, there are many examples of staged fuel supply to the combustion zone (fuel staging), and still a small number of examples of the use of third or additional fuel, e.g. application of biogas or natural gas in combustion of pulverized solid fuels (reburning technology). General, these measures simultaneously increase the efficiency of primary energy conversion from fuel and reduce the emission of undesirable components into the environment. The results of this paper show the extent to which the effects of the use of natural gas in the co-firing of Bosnian coal and waste wood biomass are expressed. In this process there is an additional reduction of NOx in proportion to the share of gas - at a process temperature of 1350 °C and at 10% of the energy content of gas in combustion with coal, compared to emissions without additional fuel, recorded reduction of NOx emissions by more than 250 mg/mn 3.

Intermittent electricity generation of the various renewable energy sources sets additional burden on generation unit dispatching and reserve planning in day-ahead electricity market. The conventional unit commitment models which include rump-up and rump-down limits are usually presented with stepwise mathematical functions without clear distinction between power and energy. This paper presents a case study of generation unit dispatching planning approach for the case of pricewise-linear functions from one time interval to another, taking into account actual ramping trajectories thus providing more efficient reserve scheduling particularly during generators’ start-up and shut-down processes. For the representation of reserve schedules, the 10-min and 30-min ramp capabilities of the generation units are assumed where they are obliged to provide secondary, tertiary and offline-tertiary reserves depending on their technical capabilities. The Serbian power system case study represents a 24-hour unit commitment planning and up/down secondary and tertiary reserve requirements during a scarcity event when reserve flexibility of neighbouring power systems cannot be utilised. Formulation of the optimisation mathematical model is performed via GAMS, the General Algebraic Modelling System, and CPLEX optimiser is used for problem optimisation purposes.

Industry processes are characterized by large amounts of energy losses dissipated as waste heat to the ambient. In industry sectors analysed in the US, China and EU28 lowtemperature waste heat below 230ºC makes up from 33% up to 60% of waste heat. The recovery of low-temperature waste heat is usually complex, affected by the user demand, mismatches between the waste heat source and the user demand, limited space for heat recovery facilities, the heat-power conversion is not efficient for low-temperature waste heat, payback period, etc. The purpose of this paper is to present a methodology for technical and economic analysis of waste heat recovery. To address the issue of sensible criterion, methodology appropriate for small and medium enterprises is developed and in this paper, the user-friendly optimization integrating the heat exchange, energy conversion and heat storage is presented. A case study of waste heat recovery from an induction machine cooling system is used to demonstrate the applicability of the proposed methodology. The introduced methodology can simplify the heat pump integration process, and the proposed method can be further extended to other industrial processes for low-grade waste heat recovery.

Having in mind the deteriorating conditions for agricultural production due to climate change, there are more and more factors that justify the use of agro-photovoltaic or agrivoltaic systems. The systems offer an innovative, efficient and cost-effective solution for the simultaneous development of sustainable agricultural production and renewable energy production. Besides, they increase land use by synergizing agricultural infrastructure with photovoltaics, making rural communities more competitive and sustainable. In this way, farmers have the opportunity to develop a new source of income without leaving agricultural production. Installed directly above agricultural crops, solar panels protect plants from excessive sunlight, heat, maintain soil moisture, protect from hail and frost, enabling a stable yield with the simultaneous production of electricity. The benefits of using APV systems can be increased thanks to digital solutions being adapted to crop needs by optimizing the level of shading or soil moisture in relation to electricity production. Solar energy can be used to drive irrigation pumps, thus replacing diesel generators, as well as for the purpose of processing agricultural products and powering equipment and rolling stock on farms. Individual farmers as well as cooperatives can benefit from the application of these systems, given that the experience so far shows an increase in farm income of over 30%. The technical and economic feasibility of APV projects has been proven in many countries, and the lack of an appropriate regulatory framework is probably the biggest obstacle for their potential to be realized. Investments in these projects are higher compared to conventional photovoltaic systems installed on the ground so, at this moment, it is necessary to design and implement certain support measures to achieve positive economic effects in the Republic of Serbia (AP Vojvodina). Taking into account the climatic conditions in the territory of Serbia (AP Vojvodina), as well as the crops that are grown, it is necessary to examine the possibility of applying these systems primarily to vegetable and fruit crops.

The direct electricity line is a part of the structure of the electricity market which is regulated by the European Union electricity market legislations. Through the process of the transposition of the legislation under the auspices of the Energy Community and the process of Stabilization and Association with the European Union, the notion of the term of the direct electricity line has been introduced into the Republic of Serbia legislation governing energy sector. The paper will analyse the provisions of the European Union legislations and of the Republic of Serbia legislations on direct electricity line. The effects of regulating the direct electricity line in the Republic of Serbia and the possibility of building a direct electricity line in the context of the transmission and distribution electricity systems will also be analysed. The effects of the Republic of Serbia legislations on the direct electricity line on the relations on the electricity market are going to be analysed. Also, the role of the direct electricity line within distributed electricity generation and energy transition are studied. At the end, it will be proposed what should be taken into account in order to develop the electricity market while using the potential of the direct transmission line in the existing legal framework.
BULK FILL COMPOSITE RESIN RESTORATION TECHNIQUES REPLACE INCREMENTAL TECHNIQUES
Authors: Yudistian Ilma
Published: December 2022

Introduction: Shrinkage during the polymerization process is the main disadvantage of using composite resins because it creates pressure between the tooth and the restoration which causes failure of the adhesion of the composite resin to the tooth, micro-fissures, and cuspid deflection. Review: To reduce shrinkage that occurs, it is known that conventional composite resins must be inserted into the cavity incrementally or in layers with a maximum thickness of 2 mm per layer. However, the incremental insertion method has several disadvantages, namely that it requires a longer clinical time for restoration. To overcome the shortcomings of these conventional composites, Bulk-fill composite resin was introduced. Composite bulk fill is a sophisticated technology that allows composites to be directly placed on the restoration, has a low polymerization shrinkage to reduce micro-leakage, reduces stress in the presence of elasticity, increases the depth of at least 4 mm translucent at the time of application, is very conducive to light transmission, is more flowable to allow adaptation to the cavity, including cervical margins, it is easy to apply with minimal handling and is resistant to large stresses. Conclusion: With the characteristics possessed by the Bulk-fill composite resin, it is known that the bulk-fill technique in addition to reducing the clinical application time, can also improve the edge adaptation between the restoration and the tooth compared to the incremental technique, without reducing its physical strength.
