O objetivo do presente relato de caso é mostrar a reabilitação cirúrgica, protética e endodôntica de dentes com lesões interradicularares tratados ou não endodonticamente com núcleo metálico fundido (NMF) satisfatório e não satisfatório e confecção de metalocerâmica. Paciente com a necessidade cirúrgica, protética e endodôntica nos dentes 11 e 21 foi encaminhada para a clínica de prótese da Unifenas e foram realizados exame físico, clínico e radiográfico e foi observado no dente 11 NMF pré-fabricado mal adaptado, coroa metalocerâmica, ausência de tratamento endodôntico e lesão periapical. O dente 21 estava com núcleo metálico fundido justaposto com material definitivo, ausência de tratamento endodôntico, lesão radicular periapical e coroa metalocerâmica fraturada. No dente 11 foi realizado tratamento endodôntico, confecção de uma coroa provisória com dente de estoque e pino provisório com vedamento total do conduto e posteriormente foi confeccionado um núcleo metálico fundido com coroa metalocerâmica, porém após 3 meses observou-se a não regressão da lesão sendo necessário realizar a apicectomia. No dente 21 foi indicado apicectomia, curetagem e retrobturação com vedamento total do conduto para regressão da lesão e posteriormente foi confeccionado coroa metalocerâmica. Conclui-se que o sucesso de qualquer tratamento estético depende da comunicação do paciente com o profissional, e deste com as demais especialidades que envolvem o caso, assim como o planejamento correto para que o objetivo desejado seja alcançado.

As comunicações bucosinusais são acidentes das exodontias. Ocorrem geralmente em casos de exodontias dos elementos dentários superiores, principalmente nos pacientes que apresentam extensa pneumatização do seio maxilar com projeção inferior do mesmo. Caso o fechamento estanque da comunicação não seja realizado, o acidente evoluirá para uma complicação: formação de fístula bucosinusal (FBS), que estará sempre acompanhada de sinusopatia inflamatória/infecciosa. Esse trabalho teve como objetivo relatar um caso de fistula bucosinusal associada a sinusite maxilar após comunicação bucosinusal não diagnosticada e não tratada. O caso teve boa resolução mediante fechamento da fistula através de rotação de retalho vestibular.

Published: August 2023

A odontologia atual preconiza procedimentos que visam à melhora da estética, juntamente com meios mais conservadores do tecido dental e novos métodos estão sendo descritas para o alcance desse objetivo. Ultimamente muito tem se falado do uso do carvão ativado como agente clareador, um novo método que vem sendo desenvolvido e testado, prometendo um resultado excelente em relação aos demais agentes, possuindo como principal objetivo o branqueamento dentário e ausência de sensibilidade após o termino do tratamento. Este trabalho teve como objetivo relatar um caso clínico de um paciente do gênero masculino, 21 anos de idade, queixando-se de desarmonia do sorriso, dentição com coloração amarelada, com indicação para tratamento com clareador dental a base de carvão ativado, buscando analisar a eficácia ou não desse procedimento. Tendo em vista que o caso clínico relatado demonstrou um pequeno resultado satisfatório na melhora da coloração dental, acredita-se que a indicação do carvão ativado como clareador não se justifica já que seu mecanismo de ação não possui capacidade de penetração entre o esmalte e a dentina, sendo considerado apenas um dentifrício abrasivo e não um clareador dental.

Estudos têm demostrado evidências que a Doença Periodontal (DP) e o Diabetes Mellitus (DM) vivenciam uma relação bidirecional. O tratamento da doença periodontal é baseada na raspagem e no alisamento radicular, além do estímulo ao controle de biofilme. O uso de procedimentos auxiliares como a terapia fotodinâmica pode ser precioso na melhora dos resultados obtidos com o tratamento, principalmente naqueles indivíduos diabéticos. A terapia fotodinâmica (TFD) consiste na ativação de um fotossensibilizador por laser de luz vermelha de baixa potência, que quando sensibilizado irá induzir a formação de singletos do oxigênio, promovendo assim efeito toxico sobre a bactéria.  O objetivo deste trabalho é revisar a literatura acerca do papel da terapia fotodinâmica no tratamento de pacientes diabéticos portadores de periodontite. Foi realizada uma pesquisa bibliográfica de produções científicas, publicadas nos últimos cinco anos nas seguintes bases eletrônicas: MEDLINE, Cochrane Library, Dare e NGC (Guideline). Não há consenso na literatura acerca dos desfechos nos artigos avaliados. Essas divergências podem ser resultado das diversas discrepâncias metodológicas avaliadas nos artigos como o tempo de inoculação do azul de metileno ou a energia entregue no tratamento. O uso da TFD associada à raspagem e alisamento radicular resulta na melhora dos parâmetros clínicos periodontais, podendo aumentar a efetividade do tratamento, principalmente naqueles pacientes metabolicamente comprometidos.

Tectonic strain in salt rock mass based on measurements
Authors: Szczerbowski Zbigniew , Niedbalski Zbigniew , Bednarek Lukasz
Published: August 2023

The measurement method with the application of an extensometer for the detection of the manifestation of tectonic strain is presented in this paper. The instrument is operated in underground construction for engineering purposes, and the authors applied it in a deeply placed underground old mine gallery in the Bochnia Salt Mine, just at the tectonic boundary of the Outer Carpathians which is commonly considered to be a tectonically active zone. The presented study is characterized by two basic features. The first is the placement of the measurements deep in an old mine which is an environment free of atmospheric factors disturbing the detection of a tectonic signal. The second is a combination of routine measurements carried out for engineering purposes and research measurements enabling the extension of the observation of displacements in the space outside underground workings, inside the rock mass that has been penetrated by extensometer probes. The extensometric measurements have been made using three 7-meter long sections. The results showed the differentiation in the displacement rates of points placed in the side walls: in the southern profile, the annual displacements are approximately 1.5 mm and in the northern one – approximately 1 mm. The combined result corresponds to the amount of the annual convergence value which has been determined by the classical surveys in the excavation where extensometric measurements have been made. What is more, the ongoing displacements in the southern side wall involve the entire part of the rock mass which is penetrated by an extensometric probe, but the displacements in the northern side are only observed in the first 2 m of the penetrated part of the rock mass. This differentiation is interpreted by the authors as being the result of tectonic strain acting from the south exerted by the Carpathians.

Published: August 2023

The functional biomechanics of the lumbar spine have been better understood by finite element method (FEM) simulations. However, there are still areas where the behavior of soft tissues can be better modeled or described in a different way. The purpose of this research is to develop and validate a lumbar spine section intended for biomechanical research. A FE model of the 50th percentile adult male (AM) Total Human Model for Safety (THUMS) v6.1 was used to implement the modifications. The main modifications were to apply orthotropic material properties and nonlinear stress-strain behavior for ligaments, hyperelastic material properties for annulus fibrosus and nucleus pulposus, and the specific content of collagenous fibers in the annulus fibrosus ground substance. Additionally, a separation of the nucleus pulposus from surrounding bones and tissues was implemented. The FE model was subjected to different loading modes, in which intervertebral rotations and disc pressures were calculated. Loading modes contained different forces and moments acting on the lumbar section: axial forces (compression and tension), shear forces, pure moments, and combined loading modes of axial forces and pure moments. The obtained ranges of motion from the modified numerical model agreed with experimental data for all loading modes. Moreover, intradiscal pressure validation for the modified model presented a good agreement with the data available from the literature. This study demonstrated the modifications of the THUMS v6.1 model and validated the obtained numerical results with existing literature in the sub-injurious range. By applying the proposed changes, it is possible to better model the behavior of the human lumbar section under various loads and moments.

Authors: Aldabbagh Tamadher
Published: August 2023

The research redefined, summarized, categorized, and expanded the current conceptual understanding of the effect of talent management dimensions on organizational agility in the governmental sector in the UAE. The study conceptualizes the relationship between all studied constructs, which enriches the current knowledge for that specific topic. The main contribution of this research is that it is the first attempt to provide a more comprehensive explanation, and scattered literature covers the theories linking broader academic links on how talent management promotes agility through its processes (Recruitment and selection - Competence training - Development -Performance management). All affect its components (Strategic orientation towards agility - Agile organizational structures, methods, and process - Agile organizational culture - Facilities supporting agility). Moreover, it is suggested that future research may examine other talent management constructs to reflect a deep understanding of the construct's effect on organizational agility from different perspectives. One of the recommendations for future research is to determine the causal effect between variables by conducting empirical evidence through surveys and correlational analysis of the obtained data.

Authors: Sitienei Miriam , Anapapa Ayubu , Otieno Argwings
Published: August 2023

Artificial Intelligence (AI) is the human-like intelligence imbued in machines so that they can perform tasks that normally require human intelligence. Machine learning is an AI technique which carries on the concepts of predictive analytics with one important distinction: the AI system can make assumptions, test hypotheses, and learn independently. XGBoost, Extreme gradient boosting, is a popular machine-learning library for regression tasks. It implements the gradient-boosting decision tree algorithm, which combines several feeble decision trees to produce a robust predictive model. In Boosted Trees, boosting is the process of transforming poor learners into strong learners. It is an ensemble method; a weak learner is a classifier with a low correlation with classification, whereas a strong learner has a high correlation. Maize is a staple food in Kenya and having it in sufficient amounts in the country assures the farmers' food security and economic stability. Crop yield measures the seeds or grains produced by a particular plot of land. Typically, it is expressed in kilograms per hectare, bushels per acre, or sacks per acre. This study predicted maize yield in Uasin Gishu, a county in Kenya, using XGBOOST regression algorithm of machine learning. The regression model used the mixed-methods research design, the survey employed well-structured questionnaires comprising of quantitative and qualitative variables, directly administered to selected representative farmers from 30 clustered wards. The questionnaire comprised 30 variables related to maize production from 900 randomly selected maize farmers distributed across 30 wards. XGBOOST machine learning regression model was fitted, and it could predict maize yield and identify the top features or variables that affect maize yield. The model was evaluated using regression metrics Root Mean Squared Error (RMSE), Mean Squared Error (MSE), Mean Absolute Percentage Error (MAPE) and Mean Absolute Error (MAE), which values were 0.4563, 0.2082, 25.2700 and 0.3532, respectively. This algorithm was recommended for maize yield prediction.

Authors: Karimi Somayeh , Soltani Shahrzad , Jasemi Khadijeh
Published: August 2023

Our study was conducted over the period of two years and explored the impact of nitrogen fertilization and non-fertilization systems on soil health indicators and crop yield. Our study hypothesized that no fertilization coupled with cover cropping would enhance soil health, carbon content, and bulk density. This study found that excessive nitrogen fertilization had negative impact on soil health factors such as bulk density increment and carbon content decline through deeper profiles. In contrast, the no-fertilization system exhibited improved bulk density and better carbon distribution near the soil surface, suggesting that reducing or eliminating nitrogen can promote soil health and prevent long-term fertility decline. The study also highlighted the imbalanced carbon to nitrogen ratio resulting from high nitrogen fertilizer rate can negatively impact soil microbial activity and nutrient mineralization.

Authors: Borana Hitesh , Singh Ishwar
Published: August 2023

The growth, yield attributes and yield of clusterbean were influenced by various weed management treatments. The objective of the current study was to evaluate the impact of different weed management practices on growth, yield attributes and overall yield. An agronomic investigation was conducted at the Agricultural Research Station, Mandor, affiliated with the Agriculture University, Jodhpur, Rajasthan, during the Kharif season of 2018. The experimental design utilized a randomized block design (RBD) with three replications. The experiment encompassed ten treatments: W1 - weedy check, W2 - weed-free, W3 - pendimethalin at 750 g/ha (pre-emergence), W4 - imazethapyr at 40 g/ha (early post-emergence), W5 - pendimethalin + imazethapyr at 750 g/ha (pre-emergence), W6 - imazethapyr + imazamox at 50 g/ha (early post-emergence), W7 - pendimethalin at 750 g/ha (pre-emergence) + 1 hand weeding (25 days after sowing), W8 - imazethapyr at 40 g/ha (early post-emergence) + 1 hand weeding (35 days after sowing), W9 - pendimethalin + imazethapyr at 750 g/ha (pre-emergence) + 1 hand weeding (25 days after sowing), and W10 - imazethapyr + imazamox at 50 g/ha (early post-emergence) + 1 hand weeding (35 days after sowing). The early post-emergence application of imazethapyr + imazamox at 50 g/ha along with one hand weeding at 35 days after sowing resulted in significantly enhanced growth, yield attributes and overall yield. This treatment exhibited higher values for parameters such as dry matter per plant (g), plant height (cm), number of branches per plant, number of pods per plant, number of seeds per pod, 1000-seed weight (g), yields of both seed and stover and harvest index. Additionally, this treatment was comparable in effectiveness to the application of imazethapyr at 40 g/ha (early post-emergence) + 1 hand weeding at 35 days after sowing and the weed-free condition. The application of imazethapyr + imazamox at 50 g/ha + 1 hand weeding at 35 days after sowing emerged as a promising strategy during the Kharif season for achieving the highest yield and net monetary returns in clusterbean cultivation.

Authors: Lekha J. Sri , Deepika C. , Hemalatha V. , Rajendrakumar P.
Published: August 2023

A set of 64 genotypes of kodo millet comprising of germplasm accessions and released varieties were evaluated for their genetic variability, heritability, genetic advance as per cent of mean, character associations and path coefficients using 11 agro-morphological traits during kharif 2022 in an Alpha Lattice Design with two replications. The analysis of variance revealed the presence of significant variations among the genotypes for all the traits evaluated. High PCV and GCV were observed for the traits viz., plant height, number of tillers, panicle length, peduncle length, thumb length, grain yield, and fodder yield. It indicated the presence of substantial variability and a low environmental influence on these traits. High heritability combined with high genetic advance as per cent of mean (GAM) was observed for plant height, peduncle length, panicle length, and fodder yield, which indicated the predominance of additive gene action and selection based on these traits would be more reliable. Grain yield exhibited significant and positive correlation with days to 50% flowering, number of tillers, panicle length, number of racemes, test weight and fodder yield. Genotypic path analysis revealed that highest direct positive effect on grain yield was exhibited by days to 50% flowering, number of tillers, panicle length, test weight and fodder yield. Hence, the above-mentioned traits exhibiting positive significant correlation and positive direct effect on grain yield could be considered as important traits to be included in the selection criteria to achieve genetic improvement of grain yield in kodo millet.

To study the performance of different crop establishment techniques and weed management practices on growth, yield attributes, yield and economics of maize hybrid, field experiment was conducted during Summer 2023 season.The treatment comprised of different sowing methods viz., pneumatic precision planter, manual rotary dibbler and manual dibbling and these treatments were compared with varied weed management practices such as pre-emergence (PE) application with atrazine 50 %  WP @ 0.75 kg ha-1 at 3 DAS + power weeding at 20 and 40 DAS, pre-emergence (PE) application with atrazine 50 % WP @ 0.75 kgha-1 at 3 DAS + hand weeding at 20 and 40 DAS and pre-emergence (PE) application with atrazine 50 %  WP @ 0.75 kg ha-1 at 3 DAS + early post-emergence (EPoE) application with topramezone 33.6 % SC @ 25.2 g ha-1 at 20 DAS. The results revealed that manual dibbling under conventional levelled ridges and furrows and pre-emergence application of atrazine 50 % WP @ 0.75 kg ha-1 at 3 DAS through drone followed by power weeding at 20 and 40 DAS recorded the highest vigour index, root length, volume  and biomass. Early field emergence was noticed with manual dibbling under ridges and furrows which wasfollowed by pneumatic precision planter. However, higher LAI was recorded under manual rotary dibbler followed by pneumatic precision planter. Pre-emergence application of atrazine 50 % WP @ 0.75 kgha-1 at 3 DAS + hand weeding at 20 and 40 DAS had significantly less weed density and dry weight and the next best treatment was pre-emergence application with atrazine 50 % WP @ 0.75 kg ha-1 at 3 DAS + power weeding at 20 and 40 DAS. Significantly higher grain and stover yieldwas obtained under manual rotary dibbler treatment which was at par with pneumatic precision planter. Highest net returns and benefit cost ratio were observed with manual rotary dibbler followed by atrazine 50 % WP @ 0.75 kg ha-1 at 3 DAS + power weeding at 20 and 40 DAS.

Nagpur mandarin is well known globally for its excellent nutritional benefits and flavour. These all characteristics get affected during storage due to a lack of knowledge & processing techniques. One of the most important parameters which decide the quality of fruit juice during storage is cloud stability, which gets affected during storage due to the action of an enzyme named pectin methylesterase. Pectin methylesterase enzyme (PME) is a heat-resistant enzyme that impacts the juice quality by decreasing the cloud stability. Thermosonication is a technique to reduce the PME activity in juice by utilizing the principle of heat and ultrasound. Therefore, an experiment was carried out to inactivate the PME utilizing the ultrasound combined with higher temperature known as thermosensation on Nagpur mandarin (Citrus reticulata Blanco) juice. This study was initiated to calculate the effect of thermosensation treatment on the pectin methylesterase enzyme (PME) activity along with the effect of thermosensation on cloud stability in comparison with various thermal pasteurization treatments. Juice samples were thermosonicated at temperatures of 50 ℃, 55 ℃, 60 ℃, and 63 ℃ for 25, 20, 15 and 10 min respectively at a constant frequency of 40 kHz. Juice samples were also thermally pasteurized at 65 ℃, 75 ℃, 85 ℃, and 95 ℃ for 80, 60, 40, and 20 sec. Samples were analyzed after treatment at 0 days and 7 days of refrigerated storage at 4 ℃. Result indicated that thermosensation at 63 ℃ for 10 min at 40 kHz frequency showed much reduced PME activity with inactivation of 72.56% over control whereas thermal pasteurization at 95 ℃ showed inactivation of 69.31%. The same treatment also showed maximum cloud activity as compared to control and thermally pasteurized juice samples. Hence thermosensation can be used as an alternative processing technique for the inactivation of PME and cloud stability.

Published: August 2023

Biofortification is a promising agricultural approach for addressing micronutrient shortages and increasing the nutritional content of food crops. Micronutrient deficiencies, also known as "hidden hunger," continue to affect many people around the world, particularly in underdeveloped countries. This presentation emphasises the need of biofortification in solving this worldwide health issue. Biofortification tries to improve the level of important micronutrients such as iron, zinc, vitamin A, and iodine in edible plant portions by using traditional breeding techniques or current biotechnological procedures. Iron-fortified beans, zinc-enhanced rice, vitamin A-rich sweet potatoes, and iodine-enriched crops are all examples of successful biofortified crops. To maximise their impact, biofortification programmes must be integrated with nutrition education and agronomic practises, according to the abstract. Governments, research institutes, non-governmental organisations, and the commercial sector must work together to scale up biofortification activities and build healthier, more resilient communities around the world.

At the present time biodiesel are the most promising source of energy as it is renewable and can accomplished the rising energy demand. Pongamia pinnata L. (commonly known as Karanj) is an evergreen tree of family Fabaceae sub family Papilioneaceae, has been recognized as a potential source of biodiesel prepared from the oil obtained from its seeds. In the present work, biodiesel fuel was prepared by alkaline-catalyzed esterification of high free fatty acids present in Karanj oil. The transestrification reaction was performed by varying practical parameters such as NaOH percentage (0.50%, 0.75%, 1%), methanol to oil ratio ( 3:1, 6:1, 9:1), and reaction temperature and time (40°C for 2h, 60°C for 2h, room temperature for 24h) at constant stirring at 150 rpm. Optimum alkaline-catalyzed transesterification was achieved using 1% NaOH as a solid alkaline catalyst with a methanol-to-oil ratio of 1:6, temperature at 600C. The yield of methyl esters from Karanja oil under the optimal condition was 92%. The biodiesel and oil contents were analysed using Gas Chromatography and Mass Spectroscopy (GC-MS) analyser.  Fuel properties of the biodiesel obtained by transesterification were tested and found to meet the ASTM (American Society for Testing and Material) specifications.
