Penelitian ini bertujuan untuk mengetahui bagaimana pelaksanaan pembelajaran online dan dampaknya terhadap hasil belajar siswa di SMK Pratama Padang. Penelitian ini menggunakan pendekatan penelitian kualitatif dengan menggunakan metode deskriptif. Hasil penelitian ini menggambarkan bahwa pelaksanaan pembelajaran online di SMK Pratama masih berjalan kurang efektif dan efisien. Persiapan pembelajaran online baik dari guru maupun siswa di SMK Pratama masih kurang maksimal. Hal ini dikarenakan pengadaan pembelajaran online yang mendadak membuat guru, siswa, pihak sekolah ataupun orang tua siswa belum siap dalam pengadaan struktur seperti peraturan yang masih kurang jelas, penyusunan kurikulum online yag masih belum tepat, penyediaan media maupun RPP pembelajaran yang belum tepat. Selain penyediaan struktur, penyediaan infrastruktur yang mendukung pembelajaran online seperti pengadaan android, jaringan internet yang stabil, kuota internet yang dirasa mahal oleh siswa dengan perekonomian menengah kebawah dan hal lainnya juga dirasa belum tersedia secara maksimal. Selain itu motivasi belajar yang rendah menjadi salah satu faktor penghambat pembelajaran online dan berakibat buruk terhadap perolehan nilai siswa yang menjadi rendah.

Published: September 2022

Abstract—Teachers play an important role in student achievement and development so teachers are required to perform well in the learning process. In addition, teachers have a variety of tasks that are so heavy that these demands can cause teachers to be vulnerable to burnout. This study aims to find out if there is a relationship between self-efficacy and burnout in teachers. The research subjects (N=107) were teachers at two Bondowoso Vocational Schools with a minimum teaching period of 5 years. Data collection was done using Maslach Burnout Inventory (Maslach & Jackson, 1981) and Teacher Sense of Efficacy Scale (Tschannen-Moran & Woolfolk, 2001). The results of the analysis used spearman values that showed that there is a significant negative relationship (p<0.05) between self-efficacy and burnout with r = -0.398. All three aspects of self-efficacy have significant value but in teacher efficacy for classrom management aspects have the highest contribution with burnout (r = -0.406). Burnout levels in the two SMK have very low values and have a high level of self-efficacy. The level of self-efficacy is related to the low burnout rate in teachers at Bondowoso Vocational High School.

What do experimental animal models of mood disorders tell clinicians about influence of probiotics on the gut-brain axis?
Authors: Staniak Natasza , Piaseczna-Spitaleri Ewa , Biała Grażyna
Published: September 2022

It is commonly pointed out that enteric microbiota have a significant impact on the behavioral and neurophysiological parameters relevant to brain-gut axis disorders. Accordingly, many data have demonstrated that probiotics can alter the central nervous system function via this gut-brain axis and commensal bacteria consumption can ameliorate stress-related neuropsychiatric disorders. Thus, modulating the enteric microbiota is increasingly considered a new therapeutic approach for these disorders, although so far there is a lack of reliable pre-clinical and clinical data confirming the usefulness of probiotics in the treatment of affective disorders. In this review, we discuss various mechanisms linking specific probiotic bacteria with behaviors related to anhedonia and the exact mechanisms of their action, including data provided by using animal models and tests. Finally, we point to potential clinical impact resulting from future studies investigating the gut-brain axis activity with respect to the efficacy of probiotic treatment of mental disorders.

Published: September 2022

Remembering is a social action that cannot be separated from the context of the identity of both individuals and groups with the same background. Interpretation and reinterpretation of self-image, individual and group identities emerge from fragments of memories regarding events that occurred in the past. This study aims to show the representation of self-identity as a Moluccan in the collective memory of the first and second generation Moluccan women in the Netherlands. This research uses descriptive analytical method and literature study using Halbwachs (1980) approach, regarding the memory of social actions which are not only personal in nature but adhere to its collective and dynamic nature as well as a basic form of identity. The results of this study show that there are three elements of collective memory presented by the first and second generations of Moluccan women, namely interpreting the first generation as a rigid and hard generation, the Moluccan camps in the Netherlands are considered as the 'space' of Maluku as well as Maluku's inferiority in front of the Netherlands, Moluccan women are fighters and mediators in the family. This study also shows how the two generations interpret their identity: the first generation feels like Moluccans, while the second generation is in chaos of dual identity: Moluccan’s and Netherlands

Two-stage carbon condensation model during detonation of high explosives
Authors: Rubtsov I. A.
Published: September 2022

During detonating of high explosives with a negative oxygen balance, one of the products of the chemical reaction is condensed carbon. However, the lack of experimental data does not allow us to give a quantitative assessment of the carbon condensation process today. In this paper, a two-stage model of carbon condensation during the detonation of high explosives is proposed. We used small-angle X-ray scattering method to study the dynamics of the formation of carbon nanoparticles during the detonation of charges of a mixture of TNT and RDX.
Flame Structure of Ammonia/Hydrogen/Oxygen/Argon Mixtures at High Pressure

Published: September 2022

The search of alternative fuels is one of the most important issues. Hydrogen is the most attractive one since its combustion products include only water. However, due to its specific properties wide implementation of hydrogen is not possible. There is an idea to use chemical carriers of hydrogen, for example, ammonia. The addition of hydrogen, which is the product of ammonia cracking, can improve the combustion characteristics of ammonia. The work presents experimental data on the structure of NH3/H2/O2/Ar flames at 4 atm. Equivalence ratio values were 0.8, 1.0 and 1.2, NH3/H2ratio – 1/1. Flame structure was measured with molecular beam mass spectrometry with soft electron impact ionization. In the experiments, flames were stabilized on the flat burner. Temperature profiles were measured with thin S-type thermocouples. Numerical simulations were performed with PREMIX code from CHEMKIN package. The comparison of the experimental and numerical data enabled to reveal the mechanism of NH3/H2oxidation showing the best predictive capability. Experimental and numerical data showed that the nitrogen-containing species which are present in the post-flame zone are N2and NO whereas concentration of N2O and NO2is negligible. It was revealed that in terms of NO reduction slightly rich conditions are more effective. In addition, the effect of equivalence ratio on the peak concentration of NO, N2O and NO2was analyzed. Rich conditions appeared to be more effective to reduce peak concentrations of NO, N2O and NO2.

Predicting Rate of Penetration and optimization Weight on bit using Artificial Neural Networks
Authors: Nguyen Tien Hung
Published: September 2022

Obtaining the maximum Rate of Penetration (ROP) by optimization drilling parameters is the aim of every drilling engineer. This is because it could save time, reduce cost and minimize drilling problems. However, ROP depends on a lot of parameters which lead to difficulties in its prediction. Therefore, it is necessary and important to investigate a solution predicting ROP with high accuracy to determine the suitable drilling parameters. In this study, a new approach using Artificial Neural Network (ANN) has been proposed to predict ROP from real – time drilling data of several wells in Nam Rong - Doi Moi field with more than 900 datasets included important parameters such as the weight on bit (WOB), weight of mud (MW), rotary speed (RPM), standpipe pressure (SPP), flow rate (FR), torque (TQ). In the process of training the network, algorithms and the number of neurons in the hidden layer were varied to find the optimal model. The ANN model shows high accuracy when compared to actual ROP, therefore it can be recommended as an effective and suitable method to predict the ROP of other wells in the research area. Besides, base on the proposed ANN model, authors carried out experiments and determind the optimal weight on bit value for the drilling interval from 1800 to 2300 m of wells in Nam Rong Doi Moi field
Stuck Pipe Detection in Geothermal Operation with Support Vector Machine
Authors: Sarwono Sarwono , Lukas  , Kartawidjaja Maria Angela , Wardana Raka Sudira
Published: September 2022

One of the biggest problems during drilling operation is a stuck pipe in which the drill string would stick or freeze in the well. This challenge leads to a significant amount of remedial costs and time. Many researchers have investigated different factors regarding the stuck pipe. These factors include poor hole cleaning, improper mud design, key seating, balling up of bit, accumulation of cutting and caving, poor bottom hole assembly configuration, differential pressure, etc. (Chamkalani, Pordel Shahri, and Poordad 2013). Since geothermal drilling targets lost circulation zones at reservoir depth, the chance of getting stuck pipe events becomes higher. Many publications reported that lost circulation events that lead to stuck pipe events have become the top non-productive time (NPT) contributor to costs in many geothermal drilling projects. The consequences of a stuck pipe are very costly, that include lost time when releasing the pipe, time and cost of fishing out the parted Bottom Hole Assembly (BHA), and efforts to abandon the tool(s) in the hole. Despite many observations that have been done to develop a system in avoiding stuck pipe incidents in oil and gas drilling operations using artificial intelligence (AI), few works have been developed for geothermal drilling operations. In this research, we propose a method to build an early warning system model for stuck pipe conditions based on a Support Vector Machine. Based on the experiment result Support Vector Machine Algorithm showed good performance with 89% accuracy and 81% recall for limited training dataset.

Published: September 2022

Статья посвящена исследованию вопросов тематического единства и формообразования в симфонической поэме «Метаморфозы» А. Меликова. Научная новизна статьи определяется малоизученностью данного произведения в азербайджанской музыкальной науке. Как показал анализ, комплекс всех тем поэмы объединяется лейтформулой «метаморфозы», проявляющейся на микроуровне через общую интервальную среду. В поэме складывается цепная связь между темами-вариантами одного интонационного комплекса, что позволяет определить ее структуру как сквозную вариантную моноформу

This article is devoted to the questions of thematic unity and formation in A. Melikov’s symphonic poem "Metamorphoses". The research novelty of the article is determined by the little study of this work in Azerbaijani musicology. As the analysis has shown, the complex of all themes of the poem is united by leitformula of "metamorphosis", which manifests itself at the micro-level through a common interval environment. In the poem, a chain link is formed between the themes-variants of one intonation complex, which makes it possible to define its structure as a through variant monoform

В статье предпринята попытка детального освещения локальной музыкальной традиции астраханских казахов в контексте взаимодействия с культурами соседних, родственных по языковой группе, вероисповеданию народов (ногайцев- карагащей, юртовских татар), сохраняющих давно сложившиеся этномузыкальные традиции. Сравнительное описание современных обрядов тюркских народов нижневолжского региона, мелодико-структурный, семантико-структурный анализ приводят к одному из главных выводов о том, что в регионе образовался единый пласт музыки устной традиции в процессе симбиоза народов и культур при сохранении ими самоидентификации и, соответственно, знаковых черт своей музыкально-фольклорной культуры

The article attempts to provide a detailed coverage of the local musical tradition of the Astrakhan Kazakhs in the context of the interaction of neighboring cultures, related in terms of the language group, religion, but still carrying their own long- established ethnomusical traditions. A comparative description of the modern rituals of the Turkic peoples of the Lower Volga region, melodic-structural, semantic-structural analysis lead to one of the main conclusions that a single layer of oral tradition music has formed in the region in the process of symbiosis of peoples and cultures while preserving their self-identification and, accordingly, iconic trait of their musical and folklore culture

Interrogating Redox and Lewis Base Activations of Aminoboranes
Authors: Lee Grace , Braddock Alexander , Theodorakis Emmanuel , Romero Erik
Published: September 2022

For decades, aminoboranes were only used in amination reactions stemming from the difficulty in activating the enthalpically strong B–N bond with anything other than ionic Lewis bases (e.g., nBuLi, KOtBu, etc.). Herein, we show that the coordination of neutral Lewis bases to aminoboranes is endergonic but observable, thereby suggesting catalytic relevance. We also leverage electro- and photochemical exper-iments to show that aminoboranes can be activated via electrochemical oxidation and exhibit photochemical quenching of the excited state of commercially available fluorophores. The results presented herein represent critical insights needed for the future discovery of bona fide aminoboration reactions under mild reaction conditions.

Published: September 2022

We present an efficient deep reinforcement learning (DRL) approach to automatically construct time-dependent optimal control fields that enable desired transitions in reduced-dimensional chemical systems. Our DRL approach gives impressive performance in autonomously and efficiently constructing optimal control fields, even for cases that are difficult to converge with existing gradient-based approaches. We provide a detailed description of the algorithms and hyperparameters as well as performance metrics for our DRL-based approach. Our results demonstrate that DRL can be employed as an effective artificial intelligence approach to efficiently and autonomously design control fields in continuous quantum dynamical chemical systems.

However, how single-core magnetic nanoparticles can be employed to reduce particle concentration and concomitantly maximize assay sensitivity is not fully understood. Here, we design monodisperse Néel and Brownian relaxing magnetic nanocubes (MNCs) of different sizes and compositions. We provide insights into how to decouple physical properties of these MNCs to achieve an ultrahigh sensitivity. We find that a tri-component-based Zn0.06Co0.80Fe2.14O4 particles, with out-of-phase to initial magnetic susceptibility χ^''/χ_0 ratio of 0.47 out of nominal ratio of 0.50 for thoroughly magnetically blocked particles, show the ultrahigh magnetic sensitivity by providing rich magnetic particle spectroscopy harmonics spectrum despite bearing a lower saturation magnetization value than di-component Zn0.1Fe2.9O4 with a high value of saturation magnetization. The Zn0.06Co0.80Fe2.14O4 MNCs, coated with polyethylene glycol-based ligands, show three orders of magnitude better sensitivity than commercially available particles of comparable size.

An alumanyl anion possessing a new skeleton with N,N'-bis(2,6-diisopropylphenyl)-1,3-propanediamine ligand was synthesized and characterized. Transmetalation of this Al anion with diaminoscandium chloride precursors afforded the corresponding Al–Sc complexes possessing an unprecedented Al–Sc bond. The Al–Sc complex having Sc[N(SiMe3)2] unit underwent intramolecular C–H cleavage to form a bridged dinuclear complex with 𝜇-hydrido and 𝜇-methylene ligands. The Al–Sc complex having Sc(NiPr2)2 unit reacted with benzene in the presence of alkyl bromide to furnish a 1,4-dialuminated cyclohexadiene product with a concomitant formation of alkyl-alkyl coupled product. Although the latter product seems to form through the radical mechanism, DFT calculations revealed an ionic mechanism involving the following four steps: (1) C–Br bond cleavage through cooperative participation of both the Al and Sc centers, (2) C–C bond formation by a nucleophilic attack of the resulting alkyl-Al intermediate, (3) addition of Al anion moiety to benzene mediated by scandium center to form anionic Meisenheimer type intermediate, (4) subsequent reaction of the resulting Meisenheimer intermediate with bromoalumane intermediate to form dialuminated cyclohexadiene product. Such bimetallic reaction pathways to react with alkyl bromide and benzene would provide new insight into the chemistry of metal-metal bonded compounds.
Breaking the tert-Butyllithium Contact Ion Pair: A Gateway to Alternate Selectivity in Lithiation Reactions

The selective functionalization of saturated oxygen heterocycles at positions remote to the embedded heteroatoms remains an outstanding challenge in organic synthesis. Although many methods exist for the undirected replacement of C–H bonds with heteroatomic subunits the number of site selective C–H functionalization reactions for the introduction of carbon-carbon bonds pales in comparison. This paper describes the initial stages of a long-term program aimed at elucidating how organolithium reagents can be re-engineered to selectively deprotonate and functionalize saturated heterocycles at new locations. Through rigorous NMR spectroscopic investigations, it was determined for the first time that the addition of Lewis basic phosphoramides can shift the equilibrium of strong organolithium bases, such as t-BuLi, to include the triple ion pair (t-Bu–Li–t-Bu) / L4Li which serves as a reservoir for the highly reactive separated ion pair t-Bu / L4Li . Because the Li-atom’s valences are saturated the Lewis acidity is significantly decreased and the basicity is maximized which allowed for the typical directing effects within oxygen heterocycles to be overridden and for remote sp3-CH bonds to be deprotonated. In certain cases, this enabled the removal of stronger C–H bonds in the presence of weaker C–H bonds. Furthermore, these newly accessed lithium aggregation states were leveraged to develop a simple γ-lithiation and capture protocol (lithium nucleophilic coupling – “LiNC”) of chromane heterocycles with a variety of alkyl halide electrophiles in good yields.

Las investigaciones cualitativas sobre el éxito en la vida sugieren que este constructo se explica a partir de un modelo de cinco dimensiones: superación personal, reconocimiento social, estándar social, felicidad y relaciones interpersonales. Sin embargo, este modelo aún no se ha evaluado considerando otros paradigmas que verifiquen su validez. Así, el propósito de este estudio fue someterlo a prueba a partir del análisis psicométrico de una escala. Para ello, se creó la Escala de Éxito en la Vida, que en su versión inicial constó de 72 reactivos y se aplicó en línea a 712 adultos residentes de la zona metropolitana del valle de México. A través de un análisis factorial exploratorio (AFE), se obtuvo la escala final de 43 reactivos distribuidos en seis factores que explican el 64.71 % de la varianza, con una confiabilidad de α = .95. La estructura factorial que se obtuvo se corroboró luego por medio de un análisis factorial confirmatorio (AFC). Se concluye que el éxito en la vida se explica por factores que resaltan la necesidad de mejorar personalmente, ser valorados por los demás, alejarse del estándar de éxito social, ser felices, equivocarse en el logro del éxito y desapegarse de la familia.
Evaluación psicométrica de una escala de creencias conspirativas para población peruana

Published: September 2022

El pensamiento conspirativo es la tendencia a atribuir las causas de problemas importantes a complots secretos organizados por personas que buscan causar daño a la sociedad. Si bien este pensamiento tiene consecuencias importantes, no se encuentran instrumentos validados que permitan medirlo en español. El presente estudio busca cerrar esta brecha al traducir y adaptar la General Conspiracist Beliefs Scale (GCBS) al español y analizar sus evidencias de validez y confiabilidad. Para ello, se reclutó a 316 participantes en las redes sociales y se analizó la adecuación psicométrica de la prueba. Para las evidencias de validez provenientes de la estructura factorial de la prueba, se confirmó una estructura de tres factores: conspiraciones políticas, científicas y alienígenas. Las evidencias de validez provenientes del contenido de la prueba fueron adecuadas de acuerdo al coeficiente V de Aiken. Las personas con mayores niveles de pensamiento conspirativo tuvieron también respuestas consistentes en una escala de pensamiento conspirativo de un ítem, confiaban menos en la efectividad de prácticascientíficas (y más en prácticas pseudocientíficas) y exhibieron menores niveles de reflexión cognitiva, evidenciando validez proveniente de las relaciones con otras variables. En conclusión, la GCBS es una medida adecuada del pensamiento conspirativo en español.

Cancer cervix accounts for 80% of female genital cancer and is the most common genital cancer. India accounts for 27% of the incidence all over the world. The mortality due to cancer cervix is 14.7%. To  assess the reliability of downstaging in early detection of the precancerous lesion. To correlate the findings in 110 women with unhealthy cervix by cytology, colposcopy directed biopsies. The work was carried out continuously over one year and 2 months. 110 women were evaluated. When Cytology was compared with Colposcopy, Cytology had only 38.8% sensitivity. Cytology showed higher specificity (98.4%). 95% of the patients with abnormal Cytology had abnormal colposcopy. Colposcopy showed a sensitivity of 96.3% and a specificity of 72.3%. Sensitivity was more than a Pap smear, but specificity was less than  a pap smear. Thus, colposcopy offers an excellent tool for evaluating cervical lesions. It is an easy and perspective method, and its importance lies in teaching, diagnosis and management of cervical lesions, neoplastic and non- neoplastic.

Для пришвидшення селекційного процесу активно залучаються різноманітні методи, які реалізують динамічні реакції недиференційованих клітин. У той же час виникає потреба у порівняльному аналізі показників, які в об’єкті дослідження протікають як на клітинному рівні, так і в інтактної рослини. Це стосується і пшениці озимої. З цією метою здійснюється моніторинг несупере-чливих параметрів життєдіяльності організму, які реалізуються як на рівні цілісної рослини, так і в недиференційованих клітин. Застосовано стандартні протоколи культури клітин, біохімічні та електрофоретичні методи. Отримано клітинні культури нових гос-подарсько-цінних генотипів пшениці озимої селекції ІФРГ НАНУ. Встановлено особливості розвитку клітинних систем за біохіміч-ними показниками та зроблено їх порівняння із характеристиками рослин. Генотипи пшениці озимої при культивуванні за нормальних умов проявляли спільні риси функціонування. Рослини та клітинні культури, отримані з нових генотипів пшениці озимої, проявляли особливості свого метаболізму, залежні від умов культивування. Встановлено подібність між показниками рівня вільного проліну в рослин та отриманих із них клітинних культур. Рівень вільного проліну доцільно аналізувати при паралельному дослі-дженні білкового пулу генотипів.
