Published: December 2024

Purpose. To determine the effect of partial replacement of basic macro fertilisers with nano chelate micro fertilisers (NCMF) on the spring wheat productivity.
Methods. The study was conducted in 2019–2020 at the Plant Breeding Department of the National University of Bioresources and Nature Management of Ukraine (Kyiv). Field experiments were carried out at the educational and scientific laboratory Demonstration and Collection Crop Field. Laboratory analyses were performed at the laboratories Quality of Seeds and Planting Material and Analytical Studies in Crop Production. Nano chelate micro fertilisers were used according to the replacement scheme developed by the manufacturer (Innoparmis Agroscience SRL) in two stages: at the beginning of the stem emergence (BBCH 30–32) and at the beginning of grain filling (BBCH 71–75). A single plot area was 2 m2 in six replications.
Results. Partial replacement of the application rate with nano chelate micro fertilisers can have a positive effect on wheat yield and compensate for up to 30% of the application rate of each of the macronutrients. In the block of replacing mineral nitrogen with nano chelate micro fertilisers, the highest reliable yield reached 3.97 t/ha in the N40 + NCMF treatment with a 16.7% decrease in yield relative to control 2. In the block of phosphorus substitution, the average yield was lower and reached the maximum value of 3.52 t/ha in the treatments P40 + NCMF and P30 + NCMF. In the block of potassium replacement, yield reduction was even more significant: it did not exceed 3.2 t/ha. A significant decrease of the 1000-kernel weight by 3.7–13.1% was recorded in each of the blocks of macronutrient replacement: 40–41 g for application of only N; 37–40 g for applying only phosphorus or potassium.
Conclusions. In the fertilization system for grain crops (for example, wheat), it is possible to replace nitrogen fertilisers with nano chelate micro fertilisers by 25–30%, phosphorus and potassium by up to 40% of the recommended rate of mineral fertilisers. The yield values in these cases were 3.97 t/ha (N40 + NCMF), 3.52 t/ha (P40 + NCMF), and 3.24 t/ha (K40 + NCMF).

Authors: Ivanina V. V. , Prokopiuk T. P. 
Published: December 2024

Purpose. To investigate the influence of fertilisation and crop rotation on the accumulation of moisture in the soil and water consumption by winter wheat crops.
Меthods. Long-term field and analytical.
Results. Research data on the effect of fertilisers and crop rotation on soil moisture supply and water consumption by winter wheat is presented. It was found that the use of organic–mineral fertilisation systems in grass and grain crop rotation ensured the best conditions for the accumulation of moisture in the soil in the spring and its effective use by winter wheat crops.
Conclusions. Cultivation of winter wheat in a grass and grain crop rotation resulted in the highest amount of moisture accumulation in the soil in the spring. The reserves of productive moisture in one- and one-and-a-half-meter layers of leached chernozem in the spring were higher than in grain and row crop rotation by 15–25 mm, and in row crop rotation by 9–19 mm. In grass and grain crop rotation, winter wheat used soil moisture most effectively under the conventional organic-mineral fertilisation system. Applying N53Р42K42 + 6.7 t of manure per 1 ha of crop rotation ensured the water consumption by winter wheat of 282 m3/t, which was 141 m3/t less than in the control without fertilisers. Application of N53Р42K42 per 1 ha of crop rotation + by-products was determined to be effective: moisture consumption by winter wheat decreased by 110 m3/t compared to the control without fertilisers for an absolute indicator of 313 m3/t. In terms of crop rotation, the organic-mineral fertilisation systems reduced water consumption 1.5–1.7 times compared to the control without fertilisers.

O tempo de espera em fila é um atributo que tem grande relevância na tomada de decisão de consumo dos clientes. Nesse sentido, esse artigo tem como objetivo averiguar a probabilidade de o passageiro não esperar na fila de check-in na Companhia Aérea no Aeroporto Internacional Atlas Brasil Cantanhede em Boa Vista – Roraima. Realizou-se pesquisa quali-quantitativa e exploratória, com método de Estudo de caso. A fim de realizar triangulação de dados, realizou-se entrevista em profundidade com o gestor da companhia, com vistas a alcançar maior fidedignidade. Fez-se uso da Distribuição de Poisson para fins de averiguação no tempo de espera desde a chegada do cliente na fila de atendimento até o momento em que este é atendido. A probabilidade de nenhum passageiro aguardar em fila num período de 1 dia é de 1,83%. Nota-se que essa probabilidade é baixa, pois a probabilidade de um passageiro aguardar na fila é muito alta. Às empresas, à cidade, e ao Estado cabem repensar alguns processos, e isso, perpassa o segmento aeroviário, já que se está no Estado mais distante do Distrito Federal (DF), cujo o custo logístico amazônico é alto. O estudo é relevante para o setor aeroviário e para os gestores interessados em melhorar o atendimento ao cliente. Os resultados apresentados indicam as probabilidades de espera em fila para o check in útil para a tomada de decisões relacionadas à gestão de filas e ao investimento em tecnologias para melhorar a experiência do cliente.
The Implications of Employee Participation in Decision-Making on Employee Productivity at the Mwalimu Nyerere Memorial Academy - Karume Campus, Zanzibar
Authors: Kiwia Calvin James , Kavishe Angela Mathias 
Published: December 2024

The researchers aimed to examine the implication of employee participation in decision-making on employee productivity at the Mwalimu Nyerere Memorial Academy- Karume campus in Zanzibar. The population of the study comprised 70 academic and non-academic employees. Both probability and non-probability sampling were used to select a sample of 60 participants. Purposive sampling was used to select key informants who have managerial roles, such as Campus Directors, heads of departments, and heads of faculty while simple random sampling was used for other participants among the employees as they had an equal chance to participate in the study. The study was guided by two research objectives: to determine the extent to which employees are involved in the decision-making process and to assess the impacts of employee participation in decision-making on productivity. The study was guided by the Management by Objectives (MBO) theory which assumes that involving employees in setting goals and creating action plans leads to better participation, commitment, and alignment of objectives throughout the organisation. The study adopted a case study design. Data was collected through questionnaires and interviews. Content analysis was used to analyse qualitative information and descriptive statistics was used to analyse quantitative data. The findings show that participation in decision-making creates a sense of belongingness, honesty, and commitment among employees in the organisation. Furthermore, employee participation in decision-making allows employees to share their opinions, ideas, and skills, which enhances team cooperation and collaboration, leading to more successful decision implementation. The study concludes that employee participation in decision-making leads to improved productivity levels. The study, therefore, recommends that management should assess the reasons for employees to feel isolated from decision-making processes.
Local Interactions and Practices: A Case of Eastern Tibet's Reba Dance, China
Authors: Gao Zixuan , Ha Sang Woo , Thiagarajan Premalatha 
Published: December 2024

The Reba dance of Eastern Tibet, a vital aspect of China's intangible cultural heritage, has been significantly influenced by national cultural policies since the 1980s. This context necessitates an examination of the practices of folk groups and local intellectuals, as practical subjects, which have been overlooked in previous studies. By using the ethnographic method and Bourdieu's concept of agency, this study seeks to analyse how these two practical subjects collaborate and interact in the practice of art festivals, performances, and teaching under the structure of national policies. By exercising their agency, the study emphasises that in the preservation process, folk groups and local intellectuals play crucial roles as primary practical subjects. This study argues that, in the preservation and inheritance process of Reba dance in Eastern Tibet, the relationship between the state, local intellectuals, and folk groups is not a one-way operation of the government and intellectuals but involves a strategic interaction of multiple subjects' practices. while the state appropriates and shapes folk dance through its policies, folk groups and local intellectuals, as the practical subjects, strategically respond to these policies, further facilitating the inheritance of Reba dance.

O estatuto das ideias de contrato social e de constituição política no contexto da teorização kantiana das relações representação/objeto
Authors: Brum Torres João Carlos 
Published: December 2024

O artigo parte das afirmações de Kant de que uma constituição conforme ao direito natural é um Ideal platônico, de que, perfeita, ela é a coisa em si, e de que o pactum unionis civilis é uma ideia da razão. Assinalando que, como todas as representações, as ideias devem ser representação de algo, o texto mostra como, na análise deste ponto, Kant introduz o conceito de objeto na ideia, o que tem implicações importantes na conformação de suas filosofia política e doutrina do direito público. O desenvolvimento do texto se faz em três partes, a primeira apresenta a teoria kantiana das ideias, os termos em que nela aparece o conceito de objeto na ideia, a distinção consequente do arquétipo e do éctipo e ainda como essa distinção é especificada no caso das ideias práticas. Na segunda parte, o texto trata, primeiramente, de reconstituir como Kant, recusando o inatismo, deriva laboriosamente sua teoria do direito público do conceito de propriedade e, assim, da teoria do direito privado; depois apresenta o que se pode chamar a origem próxima do direito público, examinando o que Kant denomina o problemático e inevitável convívio lado a lado dos seres humanos e seu correlato normativo: o mandamento exeundum e statu naturali. A terceira parte cuida de mostrar que, tendo em vista que o meio de obedecer a essa injunção, o contrato social, é ele mesmo uma ideia da razão, logo um arquétipo, segue-se que, como se lê na última página da Doutrina do Direito, no plano éctipo, na vida real das sociedades, as formas de sair do estado de natureza podem ser quaisquer, sua máxima sendo “obedecei a autoridade que tem poder sobre vós”.

Published: December 2024

Recently, several studies have focused on filters to reduce or eliminate speckle noise in Porous Silicon (PS) images, aiming to enhance the metrological assessment of their applications. The objective of this study is to emphasize the significance of enhancing these smoothing and elimination processes, as they are directly linked to multiple procedures, such as the detection of interest regions. Additionally, the description of these techniques facilitates the implementation of evaluations and research with a more specific focus. The study initially addresses the definition and effets of speckle noise, followed by a detailed exploration of statistical parameters such as Signal to Noise Ratio (SNR), Peak Signal to Noise Ratio (PSNR), Structural Similarity Index (SSIM), Mean Square Error (MSE), and Root Mean Square Error (RMSE) .Finally, the results are tabulated where can these parameters provide greater certainty in the classification of the filters by considering their behavioral information in terms of perceptual quality provided by parameter metrics.
Planning and Knowledge management to develop and build the educational performance of universities
Authors: Ladjel Afifa 
Published: December 2024

Knowledge management in universities aims to gain or use knowledge to achieve a tangible economic revenue, therefore employed in the light of a vision and strategy, as it provides the necessary scientific and applied knowledge to solve problems facing workers in its department, as this system establishes dialectical relations with the prevailing culture and strategy in the environment and the economic structure deriving its resources from it and determines the features of its mechanisms, which lead to improving human capital and deepening knowledge to ensure the ability to compete through the human element and its intellectual achievements. Therefore, it was essential for us to address the topic of knowledge planning and management and building educational performance in universities through a research plan that included a conceptual framework encompassing a research problem to address the topic through previous studies. We also explained the concept of knowledge management and higher education, and discussed strategies for aligning higher education with the knowledge management era by identifying the objectives of prevailing educational transformations towards a knowledge economy. Additionally, we summarized the processes adopted by knowledge management in universities, as well as the obstacles and issues that hinder its implementation. Finally, we presented some scientific contributions that we aimed to derive from this topic in the form of scientific recommendations concerning the university and society in general.
Probable Record of Paleocene - Eocene Thermal Maximum in Southwestern Nigeria: Indications from Nannofossils of FA-1 Borehole, Eastern Benin Basin.
Authors: Adebambo Adeniyi , Falodu Ayomiposi 
Published: December 2024

The Paleocene – Eocene Thermal Maximum (PETM) interval has been reported in several calcareous nannofossil studies from Paleogene basins around world including the Southern Tethys basins of North Africa. The Southern Tethys basins are believed to be connected to the Eastern Benin Basin through the Trans – Saharan Seaway during the Paleogene. Based on these reports, we carried out a biostratigraphic and paleoclimatic analyses of the calcareous nannofossils recovered from 25 ditch cutting samples in the FA-1 borehole to investigate possible record of the PETM in the Eastern Benin Basin, Southwestern Nigeria. The samples yielded characteristic Paleocene – Eocene calcareous nannofossils species (Coccolithus pelagicus, Coccolithus formosus, Chiasmolithus solitus, Sphenolithus moriformis, Pontosphaera plana, Pontosphaera multipora, Lophodolithus mochioporus, Lophodolithus nanscens, Neochiastozygus perfectus and Zeugrhabdotus sigmoides) and the Maastrichtian species, Arkhangeskiella cymbiformis. The assemblages allow the recognition of CC 22 (Maastrichtian) and NP 4 – NP 6 (early – late Paleocene) nannofossil zones. The relatively abundant occurrences of the genus Coccolithus and Sphenolithus in the carbonate interval of borehole suggest prevailing oligotrophic, warm water condition. The barren interval succeeding the peak nannofossil abundance at sample 159 m coincides with the onset of continuous clastic sedimentation in the FA-1 borehole. This is believed to have resulted from the shoaling of the Calcite Compensation Depth (CCD) and increased clastic input occasioned by the climatic and ocean water perturbations of the PETM interval. The emergence of the genus Pontosphaera (Pontosphaera plana and Pontosphaera multipora) at depth 87 m above the barren interval suggest a return to cooler, mesotrophic to eutrophic water condition after the drastic temperature rise and oligotrophic waters of the PETM.

Key-words - Calcareous nannofossils, Paleocene - Eocene, Benin Basin, Thermal Maximum.
Automatic assessment of short answer questions: Review
Authors: Mahmood Salma Abdullbaki , Abdulsamad Marwa Ali 
Published: December 2024

With the rapid development of technology, automated assessment systems have become an essential tool to facilitate the process of correcting short answers. This research aims to explore ways to improve the accuracy of automated assessment using natural language processing techniques, such as Latent Semantic Analysis (LSA) and Longest Common Sequence (LCS) algorithm, hile highlighting the challenges associated with the scarcity of Arabic language datasets.These methodologies facilitate the assessment of both lexical and semantic congruences between student submissions and benchmark answers. The overarching objective is to establish a scalable and precise grading mechanism that reduces manual evaluation's temporal and subjective dimensions. Notwithstanding significant advancements, obstacles such as the scarcity of Arabic datasets persist as a principal impediment to effective automated grading in languages other than English. This research scrutinizes contemporary strategies within the domain, highlighting the imperative for more sophisticated models and extensive datasets to bolster the precision and adaptability of automated grading frameworks, particularly concerning Arabic textual content.

Comparison of cyclic fatigue resistance of different rotational and reciprocal file systems
Authors: Akın Tartuk Gizem , Kaya Sadullah , Al Tai Tamara Nabhan 
Published: December 2024

Aim: The purpose of this study is to compare the cyclic fatigue resistance of the TruNatomy and ProTaper Next file systems, which work rotational movements, and Reciproc and WaveOne Gold file systems, which work reciprocal movements.
Methods: ProTaper Next X2 (25/.06), WaveOne Gold Primary (25/.07), Reciproc R25 (25/.08), and TruNatomy Prime (26/.04) files were used in the cyclic fatigue test. Four groups, 15 files from each group and a total of 60 files, were rotated in an artificial canal made of curved stainless steel with a curvature angle of 60 degrees, an inner diameter of 1.5 mm, and a radius of curvature of 3 mm. The breaking times of the files were determined with a digital stopwatch, and this value was converted into the number of cycles until breaking. Compliance with normal distribution was examined with the Shapiro‒Wilk test. The number of cycles until fracture for the respective files, which did not follow a normal distribution, were compared using the Kruskal‒Wallis test and multiple comparisons were made with the Dunn test. The analysis results were presented as mean ± standard deviation and median (minimum-maximum). The significance level was taken as p<0.050.
Results: While the TruNatomy system had the highest number of cycles until fracture occurred, no statistically significant difference was found between the Reciproc and WaveOne Gold systems. The ProTaper Next system showed the lowest cyclic fatigue resistance.
Conclusion: Within the limitations of the present in vitro study, TruNatomy, which makes rotational motion, showed the best cyclic fatigue resistance. The ProTaper Next system was the file with the lowest cyclic fatigue resistance. Obtaining similar results for files produced in different shapes and with different movement kinematics allowed us to conclude that cyclic fatigue is multifactorial.

Published: December 2024

Este trabalho teve como objetivo caracterizar histopatologicamente o tecido prostático de cães (SRD). Foram coletadas 20 próstatas de cães com idades diferentes entre 1 e 15 anos. Para análise estatística foi utilizado o programa GraphPadPrism 6.0 (GraphPad Software Inc., San Diego, CA, USA), através de análise descritiva em percentual. A próstata dos cães possui semelhança morfológica e funcional com a dos humanos e é constituída por um conjunto de glândulas e estroma. É uma glândula sexual acessória com formato oval, bi lobulado do aparelho reprodutor do cão e possui como função a produção de fluido para o ejaculado que o torna propício para a motilidade e sobrevivência dos espermatozoides. Com a pesquisa obtivemos como resultado da leitura das lâminas nove animais com prostatite crônica, seis animais com hiperplasia prostática benigna e cinco animais com hipotrofia prostática. Durante a coleta observamos que os tamanhos das próstatas possuíam diferenças, sendo, nos animais castrados pouco desenvolvidas e nos inteiros as próstatas eram bem desenvolvidas. Essa observação em relação ao tamanho foi feita apenas por inspeção visual. Assim, é possível concluir que a realização da castração interfere tanto morfologicamente quanto fisiologicamente a próstata do animal, tornando o órgão atrofiado comum nos cães castrados, ou hipertrofiado nos casos dos animais inteiros.
