Published: April 2023

Objectives: This study aims to investigate the importance of strategy to increase competitive advantage which was studied from creativity, Innovative Work Behavior, and preceded by psychological empowerment through the mediating effects of the creativity, creative behavior, and moderation of digital leadershipMethodology: This study uses a quantitative approach where questionnaires are distributed to 254 SMEs in West Sumatra, Indonesia. The analysis technique used is path analysis using SEM-PLS.Finding: The results showed that psychological empowerment has a direct effect on creativity and innovative work behavior but has no effect on competitive advantage. Creativity affects innovative work behavior but does not affect competitive advantage. Innovative work behavior affects competitive advantage. Creativity mediates psychological empowerment for innovative work behavior but does not mediate competitive advantage, and innovative work behavior mediates psychological empowerment and creativity for competitive advantage. Digital leadership mediates creativity into innovative work behaviors and innovative work behaviors into competitive advantages but does not mediate psychological empowerment and creativity into competitive advantages.Conclusion: To compete in the current era, creativity is needed based on the wishes of the employees themselves so that it will be easy to shape the innovative behavior of employees. This innovative behavior will be the initiator of the development of SMEs. In addition, leaders should follow trends and technological developments and guide employees to improve their IT insight. Thus, it will accelerate the behavior change to be innovative and be able to win the competition in the current technological era.

Types of Absorptive Capacity as Antecedents of Innovation Capability: Mediating Effect of Knowledge Management
Authors: Silvianita Anita , Wijaksana Tri Indra
Published: April 2023

Objectives: The idea of absorptive capacity has become one of the most crucial ideas in the field of strategic management since it is frequently seen as a crucial component in developing innovative potential. Observations have been made regarding whether knowledge management must be present. As a result, the function of knowledge management as a mediating variable to the links between potential and realized absorptive capacity, and ultimately their effects on innovation capability, is discussed in this paper.Methodology: 180 Business Administration graduates with relevant employment experience served as our source for the data. We then observed their potential and discovered their capacity for invention, knowledge management, and absorption using SEM-PLS with SmartPLS software which was utilized as an aid in our analysis of the outcomes.Finding: Our results show that there is no significant association between either type of absorptive capacity or innovative capability. Innovative capability does not greatly lag behind absorptive capacity, whether potential or realized. However, when knowledge management is incorporated as a mediating element, realized absorptive capacity has a positive and significant indirect impact on innovative capability.Conclusion: Knowledge management has a strong mediating effect on realized absorptive capacity and has a positive as well as significant indirect impact on innovative capability

Published: April 2023

Objectives: This study aims to analyze the effect of Artificial intelligence and gamification on online purchase intention, as well as the role of customer experience as a variable that mediates the effect of artificial intelligence and gamification on online purchase intention. The marketing approach in today's era tends to lean towards digital personalization using Artificial intelligence and gamification to improve customer engagement and experience. This is ongoing with the fast rate at which technology has been expanding. The development of artificial intelligence has increased consumer happiness even more, making it even more crucial in the contemporary environment. Also, Gamification has clearly been identified as a method of influencing consumer behavior. The use of game design elements in non-game contexts is known as gamification. Gamification and persuasive technologies have been used for business purposes and to influence customer behavior.Methodology: The method used in this study is a quantitative method using survey research with marketplace users in Indonesia as the object of the research. Data collection which was used is the cross-sectional method by distributing online questionnaires from Google Forms. The research sample was selected using the purposive sampling method in order to obtain 272 respondents from various users (Tokopedia, Shopee, Lazada, Blibli, and Bukalapak users). The data analysis that is used is the path analysis Structural Equation Model (SEM) by SmartPLS 3.0 software. The first stage in data analysis is to recapitulate data on the characteristics of the respondents. The next step is to measure the validity and reliability using discriminant validity, convergent validity, composite reliability, and Cronbach's alpha.

VOZES DE UMA PAISAGEM: O VALE DOS VINHEDOS E SUA RELAÇÃO COM OS VITIVINICULTORES
Authors: Vieira Medeiros Raphael , De Souza Marcelino
Published: April 2023

A paisagem vitivinícola do Vale dos Vinhedos tem inúmeras características que a torna diferenciada, seja pelo seu caráter histórico, cultural ou econômico. Pode se dizer  então, que essa paisagem é o reflexo da humanização de um território.  A pesquisa se debruçou nas vozes daqueles que humanizaram esse território ao mostrarem suas relações identitárias, culturais e comerciais com a paisagem vitivinícola. O primeiro passo foi identificar os atores que estavam diretamente envolvidos nessa relação baseada em um critério específico. Portanto, o instrumento da pesquisa voltou-se para os produtores de vinho associados à APROVALE do ano 2020. O critério de escolha baseou-se na importância da associação com as indicações geográficas do Vale dos Vinhedos. Logo, a pesquisa teve um caráter qualitativo e exploratório. Para sua realização foram concretizadas 15 entrevistas dentre os 22 produtores associados. Não houve identificação dos entrevistados e todos assinaram termos de confidencialidade e autorização.  Enfim, a paisagem vitivinícola do Vale dos Vinhedos, embora tenha se mostrado mutável, apresenta um caráter de patrimônio cultural, uma vez que para os entrevistados, ela é a representação da história e da cultura deste território, além de ter uma importância comercial significativa com o turismo. Por isso, toda essa relação constituída entre o homem e a paisagem apresenta um caráter indentitário relevante
O GUARANI (1857), UM ROMANCE ENTRE O INDIANISMO E A ETNOGRAFIA
Authors: Ferreira Cristina , Lenz Thiago
Published: April 2023

A produção literária indianista esteve em constante diálogo com a história, ao referenciar eventos do passado e exaltar a natureza e o indígena. Sob este prisma, José de Alencar (1829–1877) publicou O Guarani (1857), romance que narrou as relações entre o indígena Goitacá Peri e a família portuguesa Mariz no século XVII. Como romance histórico, esteve pautado em uma extensa pesquisa documental, com destaque para o escrutínio do Tratado Descritivo do Brasil em 1587, de Gabriel Soares de Sousa. O objetivo desse estudo é analisar o modo como Alencar se apropriou dos escritores coloniais para a figuração do indígena em O Guarani. Ao mobilizar as crônicas de Soares de Sousa e Simão de Vasconcellos, bem como o texto histórico de Balthazar da Silva Lisboa, Alencar aproximou seu romance da prática histórico-etnográfica oitocentista, utilizando as descrições coloniais dos Tupinambá para parametrizar os hábitos e costumes dos Goitacá e Aimoré, escolha que incidiu na descrição de Peri como um indígena perspicaz e de alta estatura. Esse gesto etnográfico permitiu integrar as populações indígenas do passado colonial brasileiro e inscrever uma cultura escrita pautada na elaboração de uma retórica nacional.
MULHERES NA LITERATURA LATINO-AMERICANA
Authors: Petinelli Souza Susane
Published: April 2023

Este estudo tem como objetivo colocar em evidência a invisibilidade feminina no campo da literatura latino-americana, enfatizando a invisibilidade de mulheres negras. Para isso, será utilizada a perspectiva decolonial, com seus desdobramentos do feminismo decolonial, pois serão considerados os processos de sexualização e racialização originados com as invasões europeias. O acesso à educação também é um aspecto relevante na invisibilização. Dentre várias escritoras latino-americanas mapeadas desde os 1600, optou-se por destacar a primeira romancista negra da América Latina e, logo, do Brasil, Maria Firmina dos Reis, cujo romance Úrsula pode ser considerado uma das obras fundadoras da literatura afro-brasileira. O estudo considerou quatro de suas obras: Úrsula, “A escrava”, “Gupeva” e Cantos à beira mar, sendo possível verificar que sua produção, além de promover o protagonismo de personagens negros escravizados, traz outros aspectos relevantes para a literatura e para a sociedade, as relações patriarcais e raciais. Portanto, é possível afirmar que o invisível também tem cor, pois ainda que, historicamente, as mulheres brancas também tenham sofrido e sofram processos de invisibilização, as mulheres negras e outras mulheres de cor enfrentam maiores dificuldades e acabam sendo ainda mais invisíveis na sociedade e na literatura.
PERSPECTIVAS INTERSECCIONAIS NA MÚSICA “AS GRANFINAS” DO DISCO QUARTO DE DESPEJO: CAROLINA MARIA DE JESUS CANTANDO SUAS COMPOSIÇÕES (1961)
Authors: Alencar Thainá de Santana , Cordeiro Ribeiro Simone Beatriz
Published: April 2023

A escritora brasileira Carolina Maria de Jesus (1914-1977) denunciou, em sua obra mais difundida, Quarto de despejo: diário de uma favelada (1960), algumas das mazelas da sociedade brasileira como, por exemplo, a fome, o racismo, o classismo e o sexismo. Tais denúncias estão presentes também no disco homônimo, objeto deste estudo, lançado no ano seguinte: Quarto de despejo: Carolina Maria de Jesus cantando suas composições (1961). Deste modo, ao observar as perspectivas da interseccionalidade (AKOTIRENE, 2020) presentes no transcorrer das obras desta escritora, bem como o contexto sócio-histórico e o lugar de fala (RIBEIRO, 2020) que envolve a composição do disco, “As Granfinas”, objetiva-se verificar como se manifestam as intersecções entre raça, gênero e classe das personagens retratadas nessa música, tendo em vista que as representações femininas que surgem, apesar de compartilharem questões de gênero, são opostas: de um lado, a granfina, uma mulher branca confinada a construção mitológica da ideia de papéis de gênero, e de outro, a empregada estigmatizada às funções maternas e domésticas somadas ao racismo, em decorrência da soma da invenção colonial de gênero e raça.
The novel role of Yin Yang 1 in the acute rejection of liver allografts by activating dendritic cells
Authors: Chen Yi , Wang Bin , Liping Hong , He Wubing , Chen Lihong
Published: April 2023

Acute rejection that causes liver transplant dysfunction is the most
common cause of mortality following liver transplantation. The potential
role of Yin Yang 1 (YY1), a widely expressed zinc finger DNA-binding
transcription factor, in acute rejection of liver allografts remains
unknown. Here, we evaluated the effects and mechanisms of YY1 in an
acute rejection using major histocompatibility complex (MHC) class
II-mismatched rat liver transplantation model. On days 5 and 10 after
liver transplantation, allografts showed elevated expression of YY1 in
infiltrating inflammatory cells around the central vein of recipient
livers accompanied by elevated levels of serum transaminase and
proinflammatory cytokines. In vitro analysis showed that
YY1-overexpressing DCs had higher expression of CD80, CD86, and MHC
class II compared with the control group. Additionally,
YY1-overexpressing DCs triggered naïve CD4+ T cells to produce high
levels of intracellular cytokines IL-17 and TNF-γ. These results suggest
that YY1 activates DCs and participates in the pathogenesis of acute
rejection by polarizing naïve T cells to the inflammatory phenotype,
making YY1 a candidate therapeutic target to avoid acute rejection after
liver transplantation.

Published: April 2023

Background Neuroblastoma (NB) is a malignancy of neural crest
cells that typically occurs in children. Single nucleotide polymorphisms
(SNPs) in the fat mass and obesity associated ( FTO) gene, a
well-conserved gene, are related to tumorigenesis. However, there is a
lack of evidence regarding the relationship between FTO gene SNPs
and NB susceptibility. Methods TaqMan assay was performed to
determine associations between FTO gene SNPs and the risk of NB
in 898 patients and 1734 controls from eight medical centers in China.
And stratification analysis was performed to assess the association
between the selected FTO SNPs and NB susceptibility among
different subgroups. Results There was no significant
association between the selected FTO polymorphisms and risk of NB
in both single locus analysis and combined analysis. Conclusion
Our study shows that individuals with retroperitoneal NB and those with
III+IV NB are more likely to present with FTO SNPs than other
patients. Furthermore, participants with FTO rs8047395 GG
genotype were more likely to develop III+IV stage NB than other
participants.
Syncope secondary to arrhythmogenic left ventricular cardiomyopathy: a case report
Authors: Lin Jing , Ji Qingwei , Liu Ling , Huang Zongyan , Yang Yingxia , Shen Jie
Published: April 2023

Arrhythmogenic cardiomyopathy (ACM) is an inherited cardiac disease
characterized by fibrofatty replacement of ventricular myocardium.
Ventricular arrhythmia and sudden cardiac death (SCD) are the main
clinical manifestations[1-3](#ref-0001). ACM was previously called
arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D).
However, recent studies have shown that this disease is not limited to
the right ventricle; in ACM, biventricular involvement reaches 50%.
Subsequently, the left-dominant subtype was also identified, which
supported the adoption of the broader term “arrhythmogenic
cardiomyopathy” [1-3](#ref-0001). In this report, we describe a
case of secondary syncope in a patient with ACM who developed right
bundle branch block with ventricular tachycardia (RBBB-VT), considering
that VT originated in the left ventricle. Cardiac magnetic resonance
(CMR) of the patient showed enlargement of the left atrium and left
ventricle and significant thinning of most of the free wall of the left
ventricle. The movement of the left ventricular wall was significantly
weakened and nearly disappeared (LVEF, 30%). Late gadolinium
enhancement (LGE) and fat sequencing showed that most of the left
ventricular free wall was replaced by fibre and adipose tissue.
Therefore, the diagnosis was considered to be arrhythmogenic left
ventricular cardiomyopathy (ALVC), and CMR played a key role in the
diagnosis.
Evaluating and optimising performance of multispecies call recognisers for ecoacoustic restoration monitoring
Authors: Linke Simon , Teixeira Daniella , Turlington Katie
Published: April 2023

Monitoring the effect of ecosystem restoration can be difficult and time
consuming. Autonomous sensors, such as acoustic recorders, can aid
monitoring across long time scales. This project successfully developed,
tested and implemented call recognisers for eight species of frog in the
Murray-Darling Basin. Recognisers for all but one species performed well
and substantially better than many species recognisers reported in the
literature. We achieved this through a comprehensive development phase,
which carefully considered and refined the representativeness of
training data, as well as the construction (amplitude cut-off) and the
similarity thresholds (score cut-offs) of each call template used.
Recogniser performance was high for almost all species examined.
Recognisers for C. signifera, L. fletcherii, L. dumerilii, L. peronii,
and C. parinsignifera all performed well, with most templates having ROC
values (the proportion of true positive and true negatives) over 0.7,
and some much higher. Recognisers for L. peronii, L. fletcherii and L.
dumerilii performed particularly well in the training dataset, which
allowed for responses to environmental watering events, a restoration
activity, to be clearly observed. While slightly more involved than
building recognisers using commercial packages, the workflows ensure
that a high quality recogniser can be built and the performance
fine-tuned using multiple parameters. Using the same framework,
recognisers can be improved in future iterations. We believe that
multi-species recognisers are a highly effective and precise way to
detect the effects of ecosystem restoration.
A New Perspective on Hippocampal Synaptic Plasticity and Post-stroke Depression

Published: April 2023

Post-stroke depression (PSD), a common complication after stroke,
severely affects the recovery and quality of life of patients with
stroke. Owing to its complex mechanisms, PSD treatment remains highly
challenging. Hippocampal synaptic plasticity is one of the key factors
leading to PSD; however, the precise molecular mechanisms remain
unclear. Numerous studies have found that neurotrophic factors, protein
kinases, and neurotransmitters influence depressive behavior by
modulating hippocampal synaptic plasticity. This review further
elaborates on the role of hippocampal synaptic plasticity in PSD by
summarizing recent research and analyzing possible molecular mechanisms.
Evidence for the correlation between hippocampal mechanisms and PSD
helps to better understand the pathological process of PSD and improve
its treatment.

Published: April 2023

The aim of the study was to determine the optimal doses and methods of the
application of silicon fertilizer in barley, silage corn, and soybean under
the climatic conditions of Ukraine. A series of laboratory and field
experiments were carried out, as along with statistical and analytic data
processing. The small-plot field experiment was conducted on chernozem
podzolic soil at the NSC ?Institute for Soil Science and Agrochemistry
Research named after O.N. Sokolovsky? (Kharkiv region, Forest-Steppe of
Ukraine). The laboratory experiments were set up in Petri dishes using a
preparative form of different concentrations (0%, 0.5%, 0.75% and 1.0%) of
potassium silicate for their assessment of the germination indicators of
barley and corn seeds. The significant stimulating effect of potassium
silicate on the germination capacity and germination energy of barley and
corn seeds was shown, and the optimal concentration of the solution for
pre-sowing seed treatment was established. A high positive correlation was
determined between the amount of SiO2 application and the yield of the
studied crops (P < 0.01; R = 0,7479-0,8682). The optimal levels of the
pre-sowing application of SiO2 into the soil were established to obtain
maximum crop yields on chernozem podzolic soil (105 kg SiO2 ha-1 for barley,
92 kg SiO2ha-1 for silage corn, and 76 kg SiO2ha-1 for soybean). Also, for
each of the studied crops, the most optimal methods of the application of
silicon fertilizers were determined, which will improve their productivity
on chernozem soils.

Published: April 2023

Micronutrient malnutrition is a global challenge. However, there are
promising opportunities for combating it through the consumption of
neglected and underutilized leafy green vegetables. Senecio biafrae is an
underutilized and nutrient-rich green leafy vegetable with huge nutritional
and health potentials that have remained unexploited. The aim of this
research was to evaluate the proximate, mineral, vitamin, anti-nutrient
contents of the leaves of Senecio biafrae. Leaves of Senecio biafrae were
collected from five communities in Ekiti State and analyzed using standard
biochemical methodologies. The results showed that the leaves differed
significantly in nutritional and anti-nutritional contents. The leaves were
rich in potassium, magnesium, and calcium, and low in fat and anti-nutrient
contents for all the groups studied. The Pearson?s correlation results
showed that most of the nutritional parameters either had inverse or no
relationships with anti-nutrients. The crude protein showed significantly
positive correlations with dry matter (0.90**) and a negative correlation
with cyanogenic glycosides (-0.90**). Cyanogenic glycosides showed
significantly negative correlations with potassium (-0.63**), calcium
(-0.66**) and dry matter (-0.44*). Nitrate showed no significant
relationship with any nutritional parameter. Oxalate and tannin showed no
significant relationship with the vitamins. Phytate and tannin showed no
significant relationship with the proximate contents and minerals. The
results showed that Senecio biafrae leaf is nutrient-rich and could help to
mitigate the effects of micronutrient deficiencies. The variations and
relationships among the nutritional and anti-nutritional parameters could
enhance meaningful selection and nutritional quality through breeding.

The aim of the study was to determine the parameters of adaptability of
winter crop varieties for cultivation in the western forest-steppe zone of
Ukraine (2019-2021). The subject of the study were wheat (Triticum aestivum
L.) varieties: Vodogray bilotserkivsky, Oberig Myronivsky, Mudrist odeska;
rye (Secale ?ereale L.): Knyazhe, Kobza, Kharkivyanka; triticale
(Triticosecale Witt.): Markian, Molfar, Obrij myronivsky. The tests were
carried out in the field. The area of the experimental plot was 55 m2, and
the placement of varieties was consecutive with three repetitions. The
results showed that under the basic cultivation technologies and weather
conditions of the growing seasons, the grain productivity of soft wheat
varieties varied from 4.88 (Mudrist odeska) to 5.39 t ha-1 (Oberig
Myronivsky); rye - from 5.55 (Kharkivyanka) to 6.32 t ha-1 (Kobza);
triticale - from 6.45 (Markian) to 6.74 t ha-1 (Obrij myronivsky). The
results obtained allow to conclude that ecologically plastic varieties of
winter crops in the conditions of the studied soil-climatic zone accumulate
a sufficient amount of sugar in the tillering nodes - 25-30%, ensure
overwintering of plants - 94-96%, are resistant to the main diseases, which
contributes to the production of high-quality seeds to ensure the cultivated
area in the region and the efficiency of seed production.
The relationship between the end of the vegetation period and fruit properties in the walnut population in Eastern Serbia
Authors: Paunovic Svetlana , Miletic Rade
Published: April 2023

The main objective of the study was to examine the walnut population from the
region of Eastern Serbia for determining the relationship between the end of
the vegetation period and fruit properties (fruit weight, kernel percentage,
oil and crude protein contents). The walnut trees showed highly significant
differences in the tested parameters. The walnut population was dominated by
trees with a medium end of the vegetation period, moderate resistance to low
temperatures (39.5%) and very small fruits (23.5%). The fruits of these
trees had ? high kernel percentage (15.8%) and moderate oil and crude
protein contents (25.8% and 38.3%, respectively). Contrary, the walnut
population comprised the fewest trees of late ending of the vegetation
period, with extremely large fruits (0.1%), exceptional kernel percentage
(0.2%) and pronouncedly high oil and crude protein contents (0.07% and 0.5%,
respectively). The studied walnut trees show great variability in the date
of the end of vegetation and fruit properties, which indicates a high
potential of the population in the selection of new genotypes, and the
necessity for their conservation for further breeding, propagation and
commercial cultivation.

Entre 2017 y 2018 se realizó un estudio limnológico de 30 lagunas temporales de Costa Rica. Entre otros organismos, se estudiaron las esponjas de agua dulce (Porifera: Spongillidae), en cuya distribución se centra el presente estudio. De las muestras se aislaron 15 552 gémulas de esponjas repartidas en 21 localidades de la provincia de Guanacaste. Este material se obtuvo a lo largo de seis campañas de muestreo efectuadas entre mayo de 2017 y diciembre de 2018. Las especies de esponjas identificadas fueron Radiospongilla crateriformis (Potts, 1882), Corvoheteromeyenia heterosclera (Ezcurra de Drago, 1974), Tubella variabilis Bonetto & Ezcurra de Drago, 1973 y Ephydatia fluviatilis (Linnaeus, 1759) con nuevas localidades. Se recolectaron las cuatro especies juntas en una laguna denominada “El Sitio” y se citan dos nuevas localidades de T. variabilis en “Sainalosa” y “El Sitio” junto con Ephydatia fluviatilis y Corvoheteromeyenia heterosclera en la primera, ambas lagunas localizadas en la provincia de Guanacaste. Además, destaca la recolección de gémulas de T. variabilis aglutinadas en el tubo de alojamiento del oligoqueto Aulophorus vagus Leidy, 1880 (Annelida: Oligochaeta: Naididae). Todas las gémulas se recolectaron únicamente en la vertiente Pacífica de Costa Rica, mientras que no se encontró ninguna en las lagunas muestreadas en la vertiente Atlántica, correspondiéndose con una mayor disponibilidad de fitoplancton en la primera, y mayor transparencia y menor concentración de sales del agua en la segunda.
Hematopoietic Stem Progenitor Cells Reduce the Proliferation of Tregs via Regulation of IL-12/STAT4 Signaling During Chronic Stress
Authors: Yao Baozhen
Published: April 2023

Physical or psychological chronic stress mediates the impaired immune response by inducing the proliferation of regulatory T cells (Tregs). Our recent studies showed that hematopoietic stem progenitor cells (HSPCs) significantly modulated the immune system. HSPCs prevented stress-induced lymphocyte apoptosis, exerting a protective effect in chronic stress-induced immune responses. Thus, whether HSPCs could prevent the proliferation of Tregs in conditions of chronic stress was assessed in the present study. Injection of HSPCs inhibited the proliferation of Tregs and reduced the expression of inhibitory molecules of Tregs under conditions of chronic stress. Additionally, the protective effects of HSPCs were shown to be dependent on IL12. IL-12/STAT4 signaling in the modulation of proliferation of Tregs induced by chronic stress. When HSPC injection was co-administered with an IL-12 neutralizing antibody or selective STAT4 inhibitor in chronic stressed mice, the protective effects of HSPCs were abrogated. Injection of HSPCs increased IL-12 production by splenocytes in chronic stressed mice. These results suggest that HSPCs inhibit the proliferation of Tregs and this is dependent on IL-12 production to protect the impaired immune response.

The distillery molasses vinasse is an organo-mineral effluent which we have sought to recycle in fermentation to optimizing the fermentation and reducing its environmental impact. The vinasse produced by the NODISCAM distillery is directly discharged into the receiving environment at a daily flow rate of 120m3. The results of physicochemical analyzes show that it is acidic with a pH of 4.2; a temperature of 85.5o C at its outlet from the distillation columns. The conductivity, TDS, TA and degree Brix obtained are respectively 17349µS/cm, 8.37mg/l, 0.2o GL and 9oB; the interpretations of these parameters conclude that the vinasse is recyclable in fermentation. The five culture and fermentation tests carried out with yeast inoculum (0.1g, 0.2g, 0.3g and 0.4g) show that, for test 1 (yeast culture on vinasse) the vinasse is nutritional supplement for saccharomyces cerevisiae. Test 2 shows that the addition of a source of sugar to the previous test makes it possible to obtain an optimal yeast population necessary for fermentation, mainly for samples E6(0.3g) and E7, E8 (0.4g). Test 3 ,4 and 5 on the optimization of inputs: acid, DAP and urea show, for their part, that the addition of 0.9ml sulfuric acid during culture has the effect of prolonging the latency time of yeast the results of optimization of DAP (0.2g) without acid show that there is maximum consumption of sugar 18oB (E8) the yeast population and the rate of alcohol have values greater than or equal to the standard for all samples, a viability rate of 80,33% for sample E8 and alcohol rate after fermentation of 8oGL. Test 5 on optimization of urea show that the amount added does not really influence the results of previous test because urea is provided in part by DAP and there for optimal at 0.2g of DAP. Finally, we will say that, with recycling of the vinasse in fermentation, we optimize the fermentation in acid, DAP, urea and consequently we reduce the environmental impact of the vinasse.
Comparison Study between Different Methods Used in the Estimation of Reserves in well F-12 of Volve Field
Authors: J Metsebo
Published: April 2023

The present paper deliberates a comparison study between volumetric and material balance methods used in the estimation of reserves in well F-12 of Volve field. Based on PVT and petrophysical data, the estimation of reserves is done by using volumetric method with Excel software. The material balance method is applied on the PVT data, tank data and production history data to provide estimation by using MBAL software. The volumetric method gives estimated oil in place of about 67,639,727.94 Sm3 and so the reserve is equal to 36,525,453.09 S m3. While the stock tank original oil in place (STOIP) generated from MBAL software is 19,607,700 Sm3 and so the reserve is estimated to 10,584,378 Sm3. The volumetric method is less accurate than material balance method because it is based on the assumption that the reservoir is static and homogeneous. This is the reason why volumetric method provides an overestimated reserve. So, the material balance method seems to be the best method because of the amount and the type of production data used.
3-D Geological Mapping of Rocks Potentially Suitable for Capturing Carbon Dioxide from the Atmosphere
Authors: FP Agterberg
Published: April 2023

Rapid increase of the Anthropocene ambient air CO2 concentration value is the main cause of the 1.2 o C global temperature rise creating the recent adverse climate and weather changes. Promising new methods to capture CO2 from the air are being developed but remain too expensive for worldwide applications. Mantle-derived rocks, primarily basalts, peridotites and serpentinites are likely to play an important role in future CO2 reduction because of relatively rapid disintegration of minerals (including olivine and serpentine) in these rocks potentially resulting in widespread CO2 capture. Examples to be discussed include artificially enhanced carbonization of water emitted from ophiolites, and acid dissolution of serpentinites resulting in indirect mineral carbonation by optimizing temperature and pressure conditions. Reconstruction of a large cone-shaped body of serpentinite situated within the Mount Albert peridotite intrusion in Québec is presented as an example of the rôle 3-D geologic mapping can play in future CO2 reduction efforts.
First Evidence of Spatial Relationships between Ecosystem Functioning and Services in the marine environment
Authors: L Basconi
Published: April 2023

The complexity of the marine system and the rate of anthropogenic impacts on ecosystem functioning demand a synthetic conceptual framework to organize the scientific knowledge needed to better conserve Nature and maintain ecosystem services supply. Currently, the most used conceptual framework is the cascade model that describe a tight positive link among biodiversity, ecosystem functioning and services. The present study explores the spatial relationship between ecosystem functioning and services discussing its heterogeneity. It warns the next generation of researchers on ecosystem services to quantify even ecosystem functioning in their spatial efforts, to better set real sustainable management strategies. The unified framework of ecosystem services and ecosystem functioning assessment will further the goal for protecting nature while humans use it.
Efficacy of Biofilm Removal in Root Canals Using a Polyamide Tip Oscillating with a Frequency in kHz
Authors: Yahata Yoshio
Published: April 2023

Background: This study aimed to verify the effectiveness of polyamide tips oscillating with a frequency in the kHz range in removing intraradicular biofilms formed in vivo. Materials and Methods: An intracanal biofilm model was established using the mandibular first molar of 10-week-old male Wistar rats to compare the efficacy of a polyamide tip oscillating with a frequency in kHz (EDDY) in removing biofilms from the root canal. Biofilm removal efficacy was compared between the following groups: EDDY, conventional needle irrigation (CNI), without irrigation (positive control), and no root canal treatment (negative control). The biofilm removal efficacy was investigated using scanning electron microscopy (SEM) of the root canal wall and quantitative polymerase chain reaction for the statistical evaluation of the number of bacteria in each group. Results: SEM of the root canal wall in the CNI and positive control groups showed multi-layered biofilms, whereas the EDDY group showed less or no biofilms at the opening of the dentinal tubules in the root canal wall. Quantitative analysis showed the EDDY group had statistically significantly lower bacterial counts than the positive control group, with no difference when compared to the negative control group. Although the EDDY group had fewer bacteria remaining than the CNI group, the difference was not statistically significant. Conclusion: A polyamide tip oscillating with a frequency in the kHz range, such as EDDY, is an effective strategy for biofilm removal from the root canal, not only by agitating the irrigant but also by mechanical action on the root canal wall.

Introduction. The mining of mineral deposits is related to the construction of sophisticated technological complexes on the surface being a liaison between underground operations and above-ground systems. During construction of the mining companies’ buildings and structures of the above-ground technological complexes there arise problems related to the complicated engineering, geological and hydrogeological conditions, as well as emerge difficulties caused by the presence of underground workings (mining, transport, ventilation, auxiliary) affecting the construction and operation of surface facilities. In this article a study was made of the stress-strain state (SSS) of a complex system comprising a mine surface building, a vertical shaft mouth with a ventilation duct under conditions complicated by the presence of subsiding soils and the need of reinforcement thereof.Materials and methods. In the study there were used: the analysis of existing methods of soil bases reinforcement as applied to the specific engineering and geological conditions of construction, subject to the interdependence of aboveground and underground structures; the mathematical modeling of the system "a vertical shaft mouth with a ventilation duct - a subsiding soil mass reinforced with soil piles - a mine surface building’s foundations"; the study of SSS features on models, determination of the main factors affecting the design decisions on enforcement of soil bases and building foundations receiving a compound combination of operational loads.Results. It has been found that the above-ground loadbearing structures, foundations and soil bases should be calculated taking into account the interdependence with the vertical shaft and the adjacent ventilation duct, based on the SSS parameters definition. The monolithic concrete mouth lining has a significant impact on the SSS of the foundation slab, increasing rigidity at the points of contact between the slab and the lining. The minimum vertical settlement of the slab is observed above the shaft mouth lining, the maximum - in the central part of the building, in the points of maximum load application.Discussion and Conclusions. The results of the stress-strain state study of a reinforced soil mass and a vertical shaft mouth lining in interaction with the mine surface building’s foundations are formulated, and recommendations are given on considering the affecting factors when designing such facilities.
