Published: July 2023

Cerita rakyat merupakan media yang sangat efektif untuk menanamkan berbagai nilai dan etika kepada terhadap anak. Salah satunya adalah cerita rakyat Sidang Belawan dari Lampung. Sayangnya cerita ini sudah jarang didengar karena kurangnya media literatur. Cerita ini mengajarkan untuk tidak berbohong, bertanggung jawab, religious, tidak mudah menyerah dan berani. Anak usia golden age yaitu 0 hingga 8 tahun merupakan waktu terbaik untuk menanamkan nilai yang baik karena mudah menyerap apa yang dibacanya. Namun sayangnya perubahan jaman menurunkan minat baca anak sehingga anak lebih menyukai video dan permainan gawai dari pada membaca buku. Padahal cerita rakyat adalah salah satu media komunikasi yang efektif dalam menyampaikan pelajaran dan pesan moral kepada anak. Buku pop-up sendiri merupakan media buku interaktif yang membuat anak bisa belajar sambil bermain. Anak akan lebih tertarik membaca untuk mengetahui cerita dibalik mekanisme kertas. Sehingga diharapkan cerita lebih mudah dimengerti dan menarik minat baca anak. Metode yang digunakan sendiri adalah Mix Method berupa kuesioner, wawancara, dan studi literatur. Dengan begitu penelitian diharapkan dapat membantu memperkenalkan kembali cerita rakyat Sidang Belawan dari Lampung agar tetap lestari sekaligus menanamkan nilai budi yang luhur dan minat membaca kepada anak.

Traditional material calculation methods, such as first principles and thermodynamic simulations, have accelerated the discovery of new materials. However, these methods are difficult to construct models flexibly according to various target properties. And they will consume many computational resources and the accuracy of their predictions is not so high. In the last decade, data-driven machine learning techniques have gradually been applied to materials science, which has accumulated a large quantity of theoretical and experimental data. Machine learning is able to dig out the hidden information from these data and help to predict the properties of materials. The data in this work are obtained from the published references. And several performance-oriented algorithms are selected to build a prediction model for the hardness of high entropy alloys. A high entropy alloy hardness dataset containing 19 candidate features is trained, tested, and evaluated by using an ensemble learning algorithm: a genetic algorithm is selected to filter the 19 candidate features to obtain an optimized feature set of 8 features; a two-stage feature selection approach is then combined with a traditional solid solution strengthening theory to optimize the features, three most representative feature parameters are chosen and then used to build a random forest model for hardness prediction. The prediction accuracy achieves an R2 value of 0.9416 by using the 10-fold cross-validation method. To better understand the prediction mechanism, solid solution strengthening theory of the alloy is used to explain the hardness difference. Further, the atomic size, electronegativity and modulus mismatch features are found to have very important effects on the solid solution strengthening of high entropy alloys when genetic algorithms are used for implementing the feature selection. The machine learning algorithm and features are further used for predicting solid solution strengthening properties, resulting in an R2 of 0.8811 by using the 10-fold cross-validation method. These screened-out parameters have good transferability for various high entropy alloy systems. In view of the poor interpretability of the random forest algorithm, the SHAP interpretable machine learning method is used to dig out the internal reasoning logic of established machine learning model and clarify the mechanism of the influence of each feature on hardness. Especially, the valence electron concentration is found to have the most significant weakening effect on the hardness of high entropy alloys.
Composite basis set of plane wave and Gaussian function or spline function

By combining plane waves with Gaussian or spline functions, a new composite basis set is constructed in this work. As a non local basis vector, the plane wave basis group needs a large number of plane waves to expand all parts of the physical space, including the intermediate regions that are not important to our problems. Our basis set uses the local characteristics of Gaussian function or spline function at the same time, and controls the energy interval by selecting different plane wave vectors, in order to realize the partition solution of Hamiltonian matrix. Orthogonal normalization of composite basis sets is performed by using Gram-Schmidt’s orthogonalization method or Löwdin’s orthogonalization method. Considering the completeness of plane wave vector, a certain value of positive and negative should be selected at the same time. Here, by changing the absolute value of wave vector, we can select the eigenvalue interval to be solved. The plane wave with a specific wave vector value is equivalent to a trial solution in the region with gentle potential energy. The algorithm automatically combines local Gaussian or spline functions to match the difference in wave vector value between the trial solution and the strict solution. By selecting the absolute value of the wave vector in the plane wave function, the calculation of large Hamiltonian matrices turns into the calculation of multiple small matrices, together with reducing the basis numbers in the region where the electron potential changes smoothly, therefore, we can significantly reduce the computational time. As an example, we apply this basis set to a one-dimensional finite depth potential well. It can be found that our method significantly reduce the number of basis vectors used to expand the wave function while maintaining a suitable degree of computational accuracy. We also study the influence of different parameters on calculation accuracy. Finally, the above calculation method can be directly applied to the density functional theory (DFT) calculation of plasmons in silver nanoplates or other metal nanostructures. Given a reasonable tentative initial state, the ground state electron density distribution of the system can be solved by self-consistent solution through using DFT theory, and then the electromagnetic field distribution and optical properties of the system can be solved by using time-dependent density functional theory.

Published: July 2023

Na sociedade contemporânea, a inovação e a tecnologia são elementos-chave para a competitividade e melhoria da qualidade de vida da sociedade. Ao longo de seu processo evolutivo, a Universidade e as Instituições de Ciência e Tecnologia (CTIs) deixaram de ser instituições fechadas, detentoras de conhecimento, e passaram a assumir um protagonismo mais no ecossistema regional de inovação, gerando impacto em seu entorno. Este estudo teve como objetivo construir e aplicar um modelo que permitisse mensurar o nível de inovação de um ecossistema de CTI. Após uma vasta revisão da literatura existente, um framework foi construído e proposto, o qual foi testado e aplicado. Foram coletados dados de 49 ISTs, representativas de diversas regiões do país. Os resultados analisados mostraram que 73,5% das IST brasileiras inserem, de alguma forma, a inovação em sua estratégia político-institucional. Seus resultados como uma terceira missão mostram que 38,8% das ISTs estabelecem vínculos de alto ou muito alto nível com o ecossistema regional. Em termos de experiência com o tema, temos uma amostra dividida, com mais de 50% com mais de 10 anos de tradição no setor, 36% com mais de 15 anos, além de 43% de ISTs com menos de 5 anos de experiência. Sobre a geração de spin-offs, 25% da amostra ainda não tem resultados para mostrar, 77,3% geraram menos de 30 empresas e 10% das TICs apoiaram mais de 60 projetos. Considerando a produção de pesquisas e patentes a partir de ecossistemas, os dados mostram uma distribuição equitativa em vários níveis de maturidade. Quanto aos recursos humanos alocados para inovação, destacam-se dois grupos extremos, um com 34,7% com nível inferior à média e outro com 24,5% com alto investimento nessa linha, com mais de 20 pessoas participando do processo. Identificou-se que a grande maioria das instituições possui os chamados mecanismos de geração de negócios (incubadoras e afins), além de ambientes de inovação, sendo os conceitos dessas estruturas bastante consolidados no país. O estudo identifica que as métricas para monitoramento dos ecossistemas de inovação são mais uma forma de orientar as CTIs a fim de aprimorar suas estratégias, recursos, processos e cultura no contexto da inovação e da geração de spin offs para o mercado.

Authors: Somani Mona , Dodiya Parth , Patel Aashray , Jadawala Kruti , Joshi Chintan , Desai Neelam
Published: July 2023

Introduction: There are several reasons associated with vertical root fracture, from which biomechanical preparation can be considered as one of the predisposing factors which can increase the susceptibility to vertical root fracture. It depends upon the amount of forces used during the preparation and taper of the file systems used for the preparation. Aim: To compare vertical root fracture resistance of teeth prepared by four different rotary NiTi file systems. Materials and Methods: This was an in-vitro study conducted on 150 extracted mandibular premolars from September 2022 to November 2022. All the teeth were decoronated keeping the remaining root length of 13 mm. The roots were divided into five groups of 30 each. Group-1: Vortex blue, Group-2: Edge File X7, Group-3: Hyflex EDM, Group-4: ProTaper Gold, Group-5: Control Group. The roots were placed in silicon impression material to resemble periodontal ligament. All the root canals were negotiated to their terminus with stainless steel K Files except the control group. All teeth from each group were then prepared with their respective file systems and were obturated and sealed with composite. All the samples were then tested with a universal testing machine to evaluate the vertical root fracture. Compressive force was applied and the load necessary to fracture was recorded in newtons. Statistical analysis was done using one-way Analysis of Variance(ANOVA) followed by post-hoc Tukey test. Results: Fracture resistance of Group-5 (Control group) was the highest (522.789±98.79215), followed by Group-1 (Vortex blue) (457.964±37.75982) whereas Group-4 (ProTaper Gold) showed least resistance (349.445±33.62643). The fracture resistance of Vortex blue file system showed significant difference when compared to Hyflex EDM and ProTaper Gold file systems (p<0.001). Conclusion: The maximum amount of force needed to fracture the samples were prepared with vortex blue file while ProTaper Gold file shows minimum amount of force needed to fracture the sample.

Authors: Narang Shikha , Roychoudhury Arnav Kumar , Bala Gunjan , Dhuria Sumit , Selhi Pavneet Kaur
Published: July 2023

Introduction: Small, undifferentiated cells with high nuclearto-cytoplasmic ratios predominate in Small Round Blue Cell Tumours (SRBCT) and are characterised by their monotony. The classification of small round-cell tumours is further facilitated by Immunohistochemistry (IHC). Determine the line of differentiation using IHC, which also acts as a proxy for underlying molecular genetic changes. To identify the presence of a particular protein marker that can help with accurate cancer categorisation and diagnosis, histology uses IHC. In light of this, SRBCT are a subgroup of highly aggressive malignant neoplasms that are primarily comprised of monotonous, small, undifferentiated cells with high nuclear-to-cytoplasmic ratios. Aim: The study is aimed to analyse the role of IHC in the SRBCT to differentiate and accurately diagnose the tumour cells using molecular markers. Materials and Methods: This ambispective was conducted from August 1st, 2010 to 31 st July 2015, a total of five years. All specimens of SRBCT less than 18 years of age were analysed grossly and microscopically. The study covered patients who were in the paediatric age range. The study did not include the small, spherical, blue-cell tumours of the bone marrow. The SRBCT were distinguished and categorised using immunohistochemical staining. CD99, CD20, CD15, CD30, CD3, desmin, CD45/LCA (the Lymphocyte Common Antigen), chromogranin, Myogenin, Synaptophysin (SYP), Cytokeratin (CK), and Epithelial Membrane Antigen (EMA) were among the immunomarkers used in this investigation. Results: Total 54 cases of SRBCT were analysed. This included 12 cases of Non Hodgkin’s Lymphoma (NHL), 10 cases of Ewing/Primitive Neuroectodermal Tumours (PNETs), 12 cases of Hodgkin’s Lymphoma (HL), nine cases of rhabdomyosarcoma, four cases of neuroblastoma, two cases each of Langerhans Cell Histiocytosis (LCH) and synovial sarcoma, and one case each of olfactory neuroblastoma, sarcoma and ganglioneuroblastoma.

Introduction: The restoration of teeth, which are most often damaged by trauma or dental caries, remains the majority of general dentists’ main area of focus on a daily basis. A major cause of concern in dental practice is the failure of dental restorations. Dental practitioners tend to employ dental amalgam and composite restorations more commonly. Aim: To evaluate the preference of amalgam or composite as a posterior restorative material among different groups of dental professionals in central India. Materials and Methods: This cross-sectional study was performed among 153 dental professionals including general dentists, endodontists, other specialists and postgraduate students in central India between July 2021 to December 2021. Questionnaire containing fifteen close ended and two open ended questions assessing different methods of restoring posterior teeth in different conditions of tooth, choice of patient, physical properties and future scope of restorative material. Following validation, the questionnaire given to targeted population. Data was collected and statistically analysed using Statistical Package for Social Sciences (SPSS) software version 20.0. Comparison between different dental professional groups was performed using chi-square test. Results: A 76.9% endodontists and 83.5% postgraduate students preferred composite in routine dental practice. A 76.9% endodontists and 70.9% postgraduate students opted for restorative material depending on clinical indications. A 46.2% endodontists choose amalgam restoration as posterior restorative material in patients with poor oral hygiene. A 52.6% general dentists preferred amalgam as restorative material in large cavities over composite restoration. Most of the endodontists, general dentists and postgraduates choose composite as restorative material due to aesthetic, less enamel removal during cavity preparation and patient’s request. Postrestoration sensitivity after amalgam restoration was stated by 64.9% general dentists. Conclusion: Composite restoration was the most preferable posterior restorative material in routine dental practice among different groups of dental professionals. The ultimate decision on the best material for patients based on their clinical circumstances, teeth, and patient requests was a desirable approach to embrace.

Aim: The main aim of the study is to estimate the degree of market integration among the selected major Copra markets in India.

Place and Duration of Study: The study was carried out using the secondary data of average monthly prices of copra obtained from the AGMARKNET website from the period of 2014-2021 for Tamil Nadu and Karnataka. Copra price series data of Tamil Nadu (Anaimalai, Avalpoondurai, and Vellakoil markets) and Karnataka (Tiptur market) has been utilized for the study.

Methodology: The time-series econometric tools including the Augmented Dickey-Fuller (ADF) test, Johansen cointegration test, and Granger causality test were used for analyzing the level of market integration. E-views software has been utilized to perform the entire analysis.

Results: The unit root effects were applied to the price series for copra in the selected markets, and they were stationary at their first difference. The long-run equilibrium relationship among the copra markets revealed that the selected markets were integrated with each other. Tiptur market exhibited a bidirectional causational relationship with Anaimalai, Avalpoondurai, and Vellakoil markets. The Granger Causality test revealed the Tiptur market as the lead market, as it influenced the prices of Anaimalai, Avalpoondurai, and Vellakoil Copra markets.

Conclusion: India's coconut market is prone to volatility and uncertainty due to frequent price fluctuations. Price changes typically result from altered market conditions brought on by seasonal and annual variations in output, in addition to competition from other edible oils. The government can put measures into place to lessen price fluctuations with the aid of integrated market information and the information would also benefit the Copra producers and other market players to select the most effective market.

Dengue Hemorrhagic Fever (DHF) is a disease caused by ectoparasites. The ectoparasite in this disease is the Aedes aegypti mosquito which acts as a vector. Aedes aegypti is a type of mosquito that can carry the dengue virus that causes dengue fever. The symptoms of this disease are rarely noticed and can spread quickly. In addition, this disease also attacks all ages and can cause death. Cymbopogon nardus (L.) Rendle is an aromatic grass from the Poaceae family that produces essential oil mainly in the leaves. The essential oil from C. nardus is known as citronella oil has repellent activity. To determine the effect of citronella powder (Cymbopogon nardus) as activated charcoal packaged in bags for controlling Aedes aegypti in bathroom tubs. This study is an experimental posttest-only control group design consisting of a control group and a treatment group using activated charcoal from lemongrass at a concentration of 1%, 2%, and 2.5%, which was treated on Aedes aegypti mosquito larvae instar III five times test. Data analysis used the One-way Anova Statistical Product and Solutions (SPSS) Version 26 test. The results showed the effect of citronella powder (Cymbopogon nardus) as activated charcoal on the mortality of the third instar Aedes aegypti mosquito larvae. This is indicated by the p-value of 0.197. The high concentration of activated charcoal from lemongrass powder determines the high mortality of third instar Aedes aegypti larvae. This is indicated by the significant difference between the concentration treatments. For further research, an increase in the concentration of activated charcoal is needed to increase larval mortality.
