Authors: Alfian Devia Gahana Cindi , Tarigan Rio , Silitonga Dicky , Afisna Lathifa P.
Published: October 2024

Technological advancements have necessitated efficient cooling solutions for electronic components, particularly central processing units. Water cooling systems, employing water blocks to transfer heat from components to circulating liquid, offer superior cooling compared to traditional methods, enabling higher performance and quieter operation. This study focuses on synthesizing nanofluids by dispersing CuO nanoparticles in water/ethylene glycol. Then, the nanofluids were tested as cooling liquids in computer waterblocks to investigate their heat transfer properties and pumping power, aiming to assess their suitability for practical cooling applications. Experimental studies were conducted on CuO-ethylene glycol/water nanofluids, comprising CuO nanoparticles, 40% ethylene glycol as the base fluid, and 60% water by the total fluid volume. The tested nanoparticles volume fractions are 0.025%, 0.055%, and 0.102%. The CuO-ethylene glycol/water nanofluid was prepared through sonication at 37 kHz for 3 hours. Subsequently, the nanofluids were tested on the water block with a flow rate ranging from 0.7 to 1.9 liters per minute. The results indicate that higher CuO concentration enhances heat transfer performance. However, it is worth noting that using higher nanoparticle concentrations may necessitate increased pumping power. This study provides valuable insights into the trade-offs between heat transfer and energy consumption for CuO-based nanofluids in electronic cooling system applications.

Published: October 2024

Hybrid flow shop scheduling (HFS) involves optimizing production processes, where different manufacturing stages have varying capacities, combining parallel machine and flow shop scheduling to improve efficiency and reduce production time. Incorporating energy considerations into HFS problems has emerged as a critical area of research, driven by the growing emphasis on environmental sustainability and cost-effectiveness in manufacturing operations. This study addresses the hybrid flow shop scheduling with energy consideration (HFSE) problem, aiming to simultaneously optimize makespan and total energy consumption, two conflicting objectives. An Artificial Bee Colony (ABC) algorithm is proposed as an effective solution methodology for tackling the HFSE problem. Through an extensive computational experiment involving a well-known benchmark suite, the ABC algorithm demonstrated remarkable performance, consistently outperforming several popular metaheuristic algorithms, including Genetic Algorithms, Particle Swarm Optimization, Memetic Algorithms, and Whale Optimization Algorithm in 75% of the problems. The proposed approach's ability to efficiently explore the search space and balance the trade-offs between makespan minimization and energy consumption reduction contributed to its superior results. The ABC algorithm reduces makespan and energy consumption by 2.95% and 3.43%, respectively. This finding suggests potential benefits for manufacturing operations, including decreased production time and lower operational costs.

Published: October 2024

On-machine measurement is crucial in industrial production because it allows the measurement of the surface properties of products without having to remove them from the machine tool; however, measurement results are superimposed with the motion error caused by the table traverse. Therefore, eliminating motion errors is this field's main objective. This paper discusses measuring a surface profile using an extension of the displacement method to eliminate motion errors. The displacement method can separate the surface profile and motion error of the stages in measurement results; however, it introduces a specific cumulative error. The tolerance of the accumulated error was first investigated by simulating a one-axis measurement. The displacement method was extended to a two-axis stage to measure the surface profile and correct the stage tilt to each axis. Moreover, carbon steel finished using a face mill was measured in the experiments, and a coordinate measuring machine was used to compare the results with those of the extended displacement method. It was found that the extended displacement method was able to remove the motion error. Applying the displacement method resulted in an improvement of approximately 88.9%. Error analyses were also formulated and evaluated for sensor drift, reference piece measurement, motion error, table rotation, and thermal expansion, and the percentage of these errors in the total was clarified. The results showed that the motion error and table rotation for the y-axis of the prototype experimental apparatus were larger than the others. These errors are discussed to analyze each error and listed in the error budget. The proposed extended displacement method can eliminate motion errors despite the simplicity of the measurement principle and can be easily integrated into machine tools and other tables.

Novel Analysis on the Impact of FinTech Developments for Monetary Policy: The Case of Türkiye
Authors: Kömürcüoğlu Ömer Faruk , Akyazi Haydar
Published: October 2024

One of the most noteworthy benefits that new technological opportunities bring to economies is Financial technologies (FinTech), which makes it easier for financial services to be cheap, fast, and accessible, especially by creating more digital payment services. This high rate of digitalization in payment services changes the liquidity preferences of economic agents daily and may affect the demand for central bank money. However, the prerequisite for the central bank to carry out monetary policy and be effective is accurately predicting the demand for its own money. Therefore, the developments in FinTech, in the last decade, are among the most attention-grabbing issues for demand in money, as well as being in the leading position for central banks, which followed intimately. In this context, the aim of this study is to reveal the impacts of developments in FinTech on monetary policy for Türkiye’s real money demand. For this purpose, in order to represent the developments in financial technologies, The FinTech index, which is formed for the first time in the relevant economy using the PCA method over the period 2012:Q1–2021:Q4, is included in the model where national income, interest rate, exchange rate, and inflation are explanatory variables. Results from the ARDL approach show that FinTech developments and demand for money are co-integrated, and also an increase in FinTech reduces money demand both in the short and long-run. The causality analysis handled with the Toda-Yamamoto approach has revealed the existence of a bidirectional causality relationship between FinTech and money demand. Accordingly, Fintech developments in Türkiye have a huge potential to shape economic agents’ liquidity preferences. To maintain the effectiveness of monetary policy, the policymakers in the central bank should closely follow FinTech developments and supervise and regulate activities that will create an alternative to its currency.

Constitutive Parliament and its speakers
Authors: Kasperavičius Algis
Published: October 2024

On April of 1920, elected Constitutive Parliament term continued till the 6th of October 1922. It worked strenuously; there took place 257 ordinary meetings, which continued for some hours every day. They often ended in the next morning. The most important task of the Constitutive Parliament was to prepare a permanent Constitution of the Lithuanian Republic, but it performed other rules' publishing functions too. It performed the control of executive government institutions of all levels. The education of parliament members was much better than the middle education of Lithuanian citizens, but most of them didn't have university education. However, it wasn't a big imperfection of the just born parliamentary system of Lithuania. A diploma or an academic degree isn't identical to the broad mind and the knowledge necessary for political leaders. It can be acquired in the way of self-education too. Oratorical skills are very important as well.
In opposition to other parliaments of the West, there weren't many lawyers in the Lithuanian Constitutive Parliament, but there were oratory skills characteristic of other professions' representatives, who sometimes didn't have both the university degree and secondary education. For example, leaders of social democrats like K. Bielinis and J. Plečkaitis. Next to them, the most eminent orators were social democrats: an engineer S. Kairys, a scientist-chemist V. Čepinskis, a leader of populists M. Sleževičius, and a Christian democrat priest M. Krupavičius. In the constitutive parliament, the Right and the Left differed from each other not only in the matter of social reforms, first of all agrarian reform, but also in their standpoint on Catholic religion and the church's place in the state. Disagreements reached their culmination in 1922 during the discussion about the final wording of the constitution.
The offers of social democrats and populists were rejected because the majority of votes were held by Christian democrats. In addition, the Right used not only objective arguments but also demagogy. The Right abstained from voting for the Constitution. It was accepted by Christian democrats and by a few executives of national minorities. The anticlericalism of the Left was one of the causes that influenced the downfall of parliamentary democracy in Lithuania as a result of the revolution in December 1926.
Discussions in the Constitutive Parliament showed that its members seriously looked at the work of Constitution preparation, though they were not always able to find compromises. They weren't afraid to express their opinion, and they didn't tremble because of the reaction in Warsaw, Paris, Moscow, or London.

Kaunas Adult Institute (1941-1944)
Authors: Bubnys Gediminas , Kriaučeliūnas Zenonas Simas
Published: October 2024

Vocational training was the main goal of German professional unions.  The attitude was led by two circumstances: firstly, the lack of workers of technical professions; secondly, the wish to hold the training of new technical professions in their hands.  Vocational training was organized not only in part-time courses but in Adult Institutes as well. These were vocational schools, which were supported by the central bureau of professional unions. Kaunas Adult Institute was one of them, which was founded on the 18th of August 1941 and run by the headmaster K. Račinskis since the 16th of August 1944. Head assessor of education Dr. Pr. Germantas-Meškauskas confirmed the statute of the institute.  Later, the Adult Institute was founded in Vilnius. The increased number of institutes inspired the necessity of a new statute.  "The Temporal Statute of Adult Institute" was confirmed on the 1st of January 1942.  Since 4 February 1942, Kaunas Adult Institute has been named as "the Central Adult Institute," and the next year adult institutes were founded in Panevėžys and Šiauliai.  The Central Adult Institute didn’t last long, because the course of some specialties survived for a few years only. 336 students graduated from the institutes during the first school year. In 1944, March and April, there were 583 students in the Central Adult Institute.  The work of the central and local adult institutes was interrupted in the summer of 1944 because of the second Soviet occupation.  The work of this institution shows that even during the occupation years in Lithuania, education and professional training were not interrupted.
Arhaeological Research in Okhtyrka — the Arhaeology of War

Published: October 2024

The article is devoted to the result of archaeological research carried out on the territory of the Okhtyrka fortress of the second half of the 17th–18th centuries. Excavations were conducted in the basement of the Okhtyrka Municipal Local History Museum. The building was severely damaged because of the night bombing in spring 2022. During the reconstruction of the museum, the workers had discovered archaeological artefacts. In the result of archaeological research, there were discovered the remains of a building buried in virgin soil. The most informative were the remains of the cellar walls. In the filling of the building, there were distinguished two layers separated by a sterile one. In the lower layer, the vast majority of fragments of tiles and furnace slag were found, and in the upper layer — numerous fragments of pottery and individual finds. The analysis of the artefacts location and the general stratigraphy allows presuming preliminary conclusions. The dwelling had two levels — the ground living level with the furnace and the underground one, or a cellar. The level had a massive ceiling made of oak logs and a wooden construction made of logs with a diameter of 0.15–0.25 m. The space between the wooden construction and virgin soil was filled with yellow sand. Mostly, in the filling of the dwelling were found light clay pottery fragments and some items covered with green glaze. The tiles were decorated with stylised floral ornament. Among the imports, the most noticeable are a handle of a faience cup produced in the Ottoman Empire and fragments of clay bottles of Riga balsam. In addition, a faience ointment jar, produced in Germany or Austria in the 18th century. Based on the analysis of the finds, the time of construction of the building is dated to the 20s–30s, and the time of destruction — 70s–80s of the 18th century. The first date is indicated by a coin minted in 1731, found in a piece of preserved oak log, and the second one by the lower part of a clay bottle, found on the floor of the cellar. Some of the imported finds are related to medicine, so we can assume using the building as a pharmacy in the last years of its existing.

Serviço Social e Direito a Educação Básica no Brasil: uma análise de Dissertações e Teses do Programa de Pós-Graduação em Economia Doméstica da Universidade Federal de Viçosa
Authors: Irias Marli , Bortone Douglas Franco
Published: October 2024

O presente artigo analisa as produções acadêmicas realizadas pelo Programa de Pós-Graduação em Economia Doméstica da Universidade Federal de Viçosa (UFV), disponíveis na plataforma Locus/UFV e que datam período de 2018-2022. Objetiva-se ao final do estudo verificar como as linhas de pesquisa do referido programa têm-se interessado em analisar a inserção de assistentes sociais na rede pública de ensino e/ou como estes profissionais têm atuado na oferta de uma educação básica de qualidade. Para atender ao objetivo traçado, é feita uma análise exploratória e descritiva das dissertações e teses selecionadas. A fim de embasar e orientar a análise e discussão dos resultados, as produções de Minayo (2010), Iamamoto (2010), Piana (2009a), Piana(2009b), além do Estatuto da Criança e do Adolescente - ECA (Lei nº 8.069/90), da Lei de Diretrizes e Bases da Educação Nacional - LDB (Lei nº 9.394/96) e da Lei nº 13.935/2019, que trata sobre a prestação de serviços de psicologia e de serviço social nas escolas da rede pública de educação básica, entre outros estudos, foram de fundamental relevância. Os dados revelaram que as produções no âmbito do programa analisado não são profícuas na relação Serviço Social e Educação Básica, apesar de ser o primeiro departamento instituído na UFV, desde 2017. A pouca conexão que estes estudos possuem com Serviço Social limita-se a alguns apontamentos relacionados a implementação de políticas públicas a fim de combater, talvez amenizar a desigualdade sociocultural e econômica, que tanto impacta o desempenho escolar e a realidade das nossas crianças, adolescentes e jovens.

Authors: Fathi Amirhossein , Salehi Sepideh , Sadeghi Simin , Atash Ramin , Monirifard Rasoul , Farahmand Saeid
Published: October 2024

Electronic cigarettes (e-cigarettes) are offered to consumers as a healthier option than traditional tobacco. However, the long-term effect of non-heat-burning tobacco and e-cigarettes on periodontal and peri-implantitis is unknown. The present review evaluates the impact of electronic cigarettes on peri-implantitis and compares the results with traditional cigarettes and nonsmokers. Systematic/meta-analysis studies were searched in PubMed, MEDLINE, EMBASE, Cochrane Library, and Google Scholar until December 30, 2022. Five systematic/meta-analysis studies were identified based on the search strategy in the selected databases. The overall quality assessment of the studies showed acceptable evidence with high quality. All systematic review studies showed that compared with traditional tobacco smoke, electronic cigarettes might reduce or not change the clinical inflammatory symptoms of periodontitis and peri-implantitis, such as bleeding on probing, probing depth, peri-implant bone loss, and response to treatments. Electronic cigarettes contain nicotine, which can harm periodontal and implant health. On the other hand, a wide range of oral health consequences may be associated with using e-cigarettes. E-cigarette is a potential risk factor for the healing process and the results of implant treatment.

Restructuring Russian Christian Personal Names in the Pre-National Period: Names in -y
Authors:   Tver State University, Ganzhina Irina M.
Published: October 2024

This article is the concluding part of a series of articles investigating the derivation of the geographically limited system of Christian personal name forms during the pre-national period. Drawing on anthroponyms from Tver business texts of the 16th–17th centuries, it explores the structural reorganization of full male personal names in colloquial speech. The focus of the analysis is on the productive paradigmatic class *-jŏ, specifically full forms of anthroponyms with a soft base (ending in -y) in different variants: -iy, -ey, -ay, -oy. During the period studied, these colloquial full forms were highly diverse, with numerous phonetic and morphological variants. These variants primarily emerged from fictitious segmentation and formal alteration of the anthroponymic bases. At the same time, preference in documents is given to colloquial rather than canonical forms, which were used mainly by clergymen. The article identifies the word-formation mechanisms that facilitated the integration of foreign personal names into the Russian onomastic system, leading to the development of numerous colloquial full forms of names, particularly through structural reorganization and formal-associative relationships involving modifications to the final segment of the name. These structural transformations, combined with phonetic changes, create a unique anthroponymic pattern specific to each territory. The analysis reveals that in the 16th–17th centuries Tver documents, two forms of Christian personal names were particularly stable and frequently recurring: consonant-final truncated forms (e.g., Vlas, Nazar, Taras, Fedos) and forms ending in -ey (e.g., Vlasey, Nazarey, Tarasey, Fedosey).
Oikonymy of the Livvik Karelians
Authors:   Institute of Language, Literature and History, Karelian Research Centre of the Russian Academy of Sciences, Kuzmin Denis V.
Published: October 2024

The article investigates the settlement names in Southern (Olonets) Karelia, where the Livvik dialect of the Karelian language has been spoken for centuries. The study highlights that, in the early stages of settlement by Livvik Karelians, the development of villages was shaped by the region’s physical geography and the population’s way of life. Due to the abundance of lakes and rivers in Southern Karelia, early villages were mostly established along these water bodies. However, from the 18th century onwards, settlements began to develop on higher ground, leading to the formation of “settlement” type villages. The article focuses on the types of rural settlements and the structure of their names. The most common single-component names include oikonyms with the -l formant, typically derived from personal names. Less common are deanthroponymic patterns without a formant, and those with the formants -(i)ne, -sto, or the Russian -ovo and -shchina. Among other oikonyms, those based on geographical terms such as pogostu ‘village with a church,’ kylä and hieru ‘village’ are particularly prevalent. The study also identifies terms for smaller settlements and farmsteads, such as kodi, kondu, perti, and taloi, along with terms borrowed from Russian, like myza and khutor. The author examines why certain types of oikonyms are more common, the timeline of their adoption into the local toponymy, and the inclusion of reconstructed terms like moiživo and tula, which likely referred to small homesteads. The author concludes that the formation of the settlement system in Southern Karelia peaked in the early 20th century but began to decline with collectivisation and subsequent repressions, leading to the abandonment of many villages in the 1960s and 1970s.

Resumo: O objetivo foi comparar o consumo alimentar da população de Coari, Amazonas, Brasil, segundo a Classificação NOVA, durante as fases hidrológicas de seca e inundação dos rios amazônicos. Realizou-se um estudo epidemiológico, de base populacional e transversal. A amostra foi composta por 457 indivíduos adultos e a coleta de dados foi realizada em dois momentos, mediante um instrumento sociodemográfico, um recordatório alimentar de 24 horas, e um questionário de frequência alimentar adaptado para os hábitos locais. Os dados foram analisados pelo programa estatístico R versão 4.2.4, por meio dos testes qui-quadrado de Pearson, exato de Fischer e de Bhapkar. A amostra foi composta predominantemente pelo sexo feminino (seca = 70%/inundação = 71,2%) e pardos (seca = 65,4%/inundação = 66,2%). As refeições (café da manhã, almoço e jantar) foram realizadas pela maior parte dos entrevistados. O lanche da tarde foi a refeição intermediária mais realizada, principalmente na inundação (274/70,2%). Predominou-se o consumo de alimentos in natura ou minimamente processados nas três principais refeições (95%). Os ultraprocessados são pouco ou não são consumidos e foram citados especialmente na seca (152/33,3%; p = 0,007). Em contrapartida, o consumo de alimentos regionais (tucumã, beiju, farinha de tapioca e açaí) aumentou durante a inundação (p < 0,001). O consumo de alimentos in natura ou minimamente processados continua sendo a base da alimentação no interior do Amazonas, predominando alimentos regionais na inundação e alimentos processados e ultraprocessados na seca, demonstrando a influência, ainda que sutil, das fases hidrológicas no consumo alimentar dessa população.
Vulnerabilidades e estereótipos masculinos nas representações sociais das causas do adoecimento por câncer de próstata
Authors: Matos Widson Davi Vaz de , Palmeira Iaci Proença , Ferreira Márcia de Assunção , Pacheco Mayara Del Aguilal
Published: October 2024

Resumo: No universo consensual de pensamento, o câncer é associado à doença incurável e incapacitante, o que acarreta prejuízos que extrapolam o âmbito biológico e atinge dimensões psicoculturais e sociais de quem convive com a doença. Sob a ótica cultural, os homens constroem narrativas sobre o câncer de próstata com base nas suas experiências e contextos sociais, expressando elementos morais, éticos e sociopolíticos atribuídos à causa do adoecimento por esse tipo de câncer. O objetivo do estudo foi compreender as causas do adoecimento de câncer de próstata nas representações de homens acometidos desse tipo de câncer e suas repercussões no autocuidado. Realizou-se estudo descritivo, qualitativo, fundamentado na Teoria das Representações Sociais. Participaram 31 homens com diagnóstico de câncer de próstata matriculados em uma Unidade de Alta Complexidade em Oncologia. Os dados foram produzidos de abril a junho de 2022 por entrevista em profundidade, individual e semiestruturada. O corpus foi submetido ao software ALCESTE. A ingestão de bebida alcoólica, o tabagismo, a promiscuidade sexual e a ausência de autocuidado foram os principais comportamentos entendidos como causas do câncer, o que gera autorresponsabilização e culpa pelo adoecimento. Representações sociais das causas, traduzidas em comportamentos não alinhados ao que a moral social dita como certos, repercutem na noção moralizadora do câncer como um castigo, em que a doença expressa o caráter do paciente, ancorando-se no discurso religioso judaico-cristão, o que diminui a carga sociopolítica das vulnerabilidades masculinas e reforça estereótipos da sociedade patriarcal.

Resumo Exame de políticas públicas na gestão de recursos hídricos no Estado de São Paulo, durante o governo de Paulo Egydio Martins, entre os marcos temporais das crises internacionais do petróleo (1973-1979). As fontes são de natureza governamental, como plano de desenvolvimento, relatórios temáticos de órgãos técnicos, empresas públicas e secretarias, programas, propostas e relatos de gestores e depoimento do governador paulista. As ações políticas conduzidas no período estiveram voltadas para a construção e manutenção da legitimidade política dos governos militares na fase inicial da “transição lenta, gradual e segura”, encabeçada pela ditadura militar, seus representantes e aliados civis, nos poderes legislativos e na sociedade civil. Foram evidenciadas: relações sociais e políticas de sustentação à modernização econômica pelo planejamento estatal sob o lema do Desenvolvimento com Segurança; a instabilidade constante da legitimidade política dos governos federal e estaduais; o papel da razão técnica, do planejamento e da tecnologia na contenção e no direcionamento de mudanças sociais no Brasil.

ABSTRACT Conjugated linoleic acid (CLA) refers to a group of positional and geometric isomers of linoleic acid. Hens fed a diet supplemented with CLA exhibit increased levels of saturated fatty acids, which may influence the quality characteristics of eggs and the offspring lipid metabolism. The present study, aimed to evaluate the effect of the dietary inclusion of CLA for broiler breeders on the residual yolk sac fatty acid profile, egg quality, and hatchability. Two 58-week-old Cobb500® broiler breeder commercial flocks were fed diets supplemented with 0% or 0.025% CLA (trans-10, cis-12). After 26 days, 300 eggs from each treatment group were collected, and among these eggs, 30 were subjected to egg quality assessment and egg yolk fatty acid profile analysis. The remaining 270 eggs were subjected to incubation analysis. The quality of the chicks was evaluated at hatch. The residual yolk sac content and weight at hatch were also evaluated. Unhatched eggs were subjected to residual analysis. The supplementation of the breeders’ diet with 0.025% CLA did not influence the incubation parameters and the weight of the chicks at hatch. However, the egg yolk and residual yolk sac fatty acid profile were altered and CLA accumulation was increased in the residual yolk sac at hatch in this treatment group. In conclusion, CLA supplementation in the diet of breeders did not influence the incubation parameters and the weight of the chicks, although it did alter the profiles of omega-6, palmitoleic, linoleic, and arachidonic acids in both egg yolk and residual yolk sac.

ABSTRACT The Junín sheep contribute to livestock production in the Peruvian Andes, but face problems related to gastrointestinal parasitism. In this study, we estimated the heritability and repeatability of traits associated with resistance to gastrointestinal parasitism in the genetic nucleus of Junín sheep raised at altitudes above 3600 m. For this purpose, fecal and blood samples were collected from 101 female lambs and 88 male lambs (4-6 months old) during the rainy and dry seasons. The data on live weight (LW), the FAMACHA score (FS), blood hematocrit (HCT), and the fecal egg count (FEC) were analyzed using a repeated multiple-trait animal model; the variance components and genetic parameters were estimated using a Bayesian inferential approach. The results showed that heritability estimates ranged from 0.09 (FS) to 0.27 (LW), with 95% high posterior density intervals (HPD95%) between [0.02-0.19] and [0.12-0.43], respectively. The repeatability ranged from 0.15 (FS) [HPD95%: 0.04-0.27] to 0.74 (LW) [HPD95%: 0.67-0.81]. The genetic correlations were moderate to low, with HPD95% intervals including zero. This indicated that, at least based on the data collected, no clear relationships occurred between traits that were selected for application in a breeding program. However, focusing the breeding program on the FEC, with a heritability of 0.16 [HPD95%: 0.05-0.28], could be a viable strategy to increase resistance to parasitism. Additional data on other traits are also needed to achieve more precise estimates for this population.
Curcumin encapsulation through complex coacervation using carboxymethylated tara gum and lysozyme: Methodology, characterization, and incorporation in bread

Abstract Curcumin obtained from Curcuma longa is a polyphenol that has been used in traditional Indian and Chinese medicine for centuries. It was also incorporated into foods through encapsulation to include its health benefits in daily diet. The present study aimed to microencapsulate curcumin through complex coacervation using lysozyme (LSZ) and carboxymethylated tara gum (CMTG) and then incorporate it into bread. Curcumin encapsulation through complex coacervation was performed using different core/wall ratios and total biopolymer concentration. The complexes of LSZ and CMTG formed at pH 5.0 exhibited electrostatic attraction with high affinity and an excellent curcumin encapsulation efficiency of 74.86%. The microcapsules protected curcumin during the oral and gastric phases, with an average release of 77% to 94% in the intestinal phase. After gastrointestinal digestion, the bioaccessibility of the encapsulated curcumin was approximately 47%. The bread in which the curcumin was encapsulated exhibited antioxidant activity (FRAP and DPPH+), with 93.9% curcumin preservation after cooking and 31% bioaccessibility. Therefore, the microcapsules containing curcumin formed after the complex coacervation of lysozyme and carboxymethylated tara gum may be used for the enrichment of bakery products such as bread.

ABSTRACT The biological activity assessment using the dynamic laser speckle (DLS) technique is recognized as a feasible methodology to analyze seeds vigor. Nevertheless, the technique presents the accessibility as a restriction to final users, and the large size of the equipment is a key limitation to allow the portability of the DLS. This work aimed to propose a reduced and portable configuration of the image capture system adopted in the DLS technique for seed analysis applications. A compacted digital camera with an embedded magnification, known by mini microscope, was tested associated with adapted diaphragm as an alternative to the traditional CCD camera, macro zoom and integrated diaphragm. The tests of the proposed adapted mini microscope, in comparison to the traditional configuration, were carried out in the monitoring of drying a paint and in the separation of high-vigor from early-aged seeds. Diaphragms with three different apertures (3, 4 and 5 mm) were evaluated. The results using the 3 mm diameter aperture presented the best performance, like in the case of the traditional CCD camera set. It was possible to follow the drying of a paint activity compared to its loss of weight and to distinguish statistically high-vigor from early-aged seeds at a significance level of 5%. The reliable results of the proposed configuration offered a compact and portable version for using the DLS in seed analysis laboratories.

Abstract Debates about the effects of covid-19 on the dynamics of food systems abounded in the last years. Initial analyses projected major changes in these dynamics due to, among other things, the digitisation of markets. Based on data collected between 2020 e 2023 by means of direct observations and 64 semi-structured interviews with farmers, rural extensionists, public officials, and community leaders in the scope of a multi-case study, and in dialogue with the sociological literature on institutional change and social construction of markets, this article analyses grassroots initiatives of market digitisation in two regions (Litoral Norte and Médio-Alto Uruguai) of the state of Rio Grande do Sul, Brazil. Findings suggest that the pandemic promoted a barred window of opportunity for social movements’ initiatives of alternative food markets. By the end of 2023, half a year after the World Health Organization declared “with great hope” an end to covid-19, it did not seem to be much hope for these initiatives. This is because neither the pandemic proved to be a “critical juncture” that opened the space for significant institutional changes, nor the challenging actors in the field were able to become “institutional entrepreneurs” of these changes.

ABSTRACT Prieurella lenticellata sp. nov. is here described and illustrated as a new species endemic to the Amazon rainforest. It is morphologically similar to P. manaosensis, but differs by having trunks with relatively larger circumference, coriaceous and smaller leaves, cuneate to truncate leaf bases, and glabrescent fruits with numerous lenticels. The verrucous testa is addressed as an important generic feature of Prieurella. This new species is only known from northern Brazil and its border with French Guiana. It occurs in terra firme forest, on clayey soil in plain areas. Considering its occurrence in protected areas and its wide distribution, we suggest a preliminary conservation status as Least Concern, according to IUCN criteria. An identification key to all accepted species of Prieurella is included.
