WATER PHASE CONCENTRATE SOLUBILITY TEST SNAKEHEAD FISH EXTRACT (Channa Striata) IN ORGANIC COSOLVENT
Authors: Andrie Mohamad , Wintari Taurina
Published: May 2023

Snakehead fish extract has been recognized for its potential in healing postoperative wounds and burns. The extract contains albumin, which aids in tissue formation and healing processes. To create a high-quality wound healing drug, the extract needs to be formulated into a concentrated form and combined with a solvent that can effectively dissolve its active substances. Understanding the solubility profile of the extract and the composition of the solvent is crucial for this purpose. This study aims to determine the solubility profile of the aqueous phase concentrate of snakehead fish extract in an organic co-solvent. Solubility is an important parameter as it can impact the release rate and therapeutic effectiveness of the drug. A solubility test was conducted to assess the solubility of the aqueous phase concentrate in various solvents. The results of the solubility test indicated that the aqueous phase concentrate of snakehead fish extract exhibited good solubility in aquadest (20%), slight solubility in propylene glycol (8.5%) and honey (2%), and was insoluble in ethanol, glycerin, mannitol, and sorbitol (0%). These findings provide valuable information for formulating the extract into a wound healing drug with an appropriate solvent composition, ensuring optimal solubility and therapeutic efficacy according to pharmacopeial standards.

Da leitura crítica do ensino para o ensino da leitura crítica: enfrentando sentidos hegemônicos
Authors: BARRETO Raquel Goulart
Published: May 2023

A importância da leitura no processo de escolarização parece evidente a ponto de não constituir objeto de questionamento. Por outro lado, é preciso marcar a ausência de consenso quanto ao que seja/signifique leitura. Diferentes concepções retomam e remetem a teorizações que abrangem da decodificação à negociação de sentidos. A última é assumida neste trabalho que, visando à leitura como exercício crítico, está centrado na integração teoria-prática, conteúdo-forma, leitura-produção textual, assim como na articulação do contexto histórico mais amplo à prática pedagógica desenvolvida na escola básica e das propostas curriculares a princípios de ação que possam aperfeiçoar situações concretas de ensino. Considerando que a prática pedagógica implica a produção de sentidos, na qual produtos se repõem continuamente como processos, a leitura crítica abrange múltiplas perspectivas, determinadas principalmente pelo corte de classe social, mas também pelas posições relativas que os sujeitos ocupam em "condições de produção" específicas. Na medida em que a produção de sentidos constitui as práticas de linguagem, duas tendências diversas, mas igualmente discutíveis, se delineiam: (1) a tomada destas práticas pela educação como um todo ou, até mesmo, pela "realidade"; e (2) a institucionalização de práticas discursivas rígidas e limitadoras. Como a linguagem está sempre atada ao poder, o discurso, instância histórica da primeira, não tem apenas implicações culturais, mas principalmente políticas: é socialmente regulado de forma a garantir a produção e a circularidade de efeitos dos sentidos hegemônicos. A Análise de Discurso (AD) constitui instrumental teórico-metodológico para a desconstrução deste processo ideológico, trabalhando pistas linguísticas que remetem aos modos pelos quais o funcionamento discursivo pode ser regulado. Ao fazê-lo, também aponta para modos de produção de sentidos diversos e para o confronto de perspectivas. Em síntese, a AD pode subsidiar a produção de um conjunto de princípios que orientem o ensino da língua, no qual a leitura crítica ocupa lugar central. É sobre esses princípios que a tese está estruturada, nos seus quatro capítulos: (1) análise da construção do objeto; (2) caracterização da palavra consentida; (3) articulação do discurso crítico; e (4) o discurso como fundamento-ação.

Authors: Peri Peri , Yuhendri Muldi
Published: May 2023

Technological developments, electronic components and circuits have resulted in a direct voltage supply system that is produced by converting the input DC voltage to another form of DC voltage with a higher output utilizing a boost converter circuit, using a low source voltage where the output voltage can be changed according to user requirements. To anticipate the voltage drop on the output side which is affected by changes in the resistance value of the load and changes in the value of the source voltage, a voltage control is needed that can regulate the output stability of the boost converter. One of the voltage control techniques used is integral proportional controller (PI). This study uses the Ziggler – Nichols oscillation method which is applied to the integral proportional controller (PI) in the boost converter circuit by using the Arduino Mega2650 as a controller circuit which is programmed with Matlab Simulink and a voltage sensor that functions to detect output on the boost converter as well as feedback from the Proportional Integral (PI) controller which will later be compared with the desired setpoint to produce the appropriate Pulse width Modulation (PWM) signal. The test results show that the PI controller works well in accordance with the purpose of adjusting the output voltage on the boost converter. This can be seen in the output of the boost converter which is in accordance with the reference voltage of 15 volts, 20 volts, and 24 volts with an output voltage of 15.36 volts, 20.52 volts, 24.82 volts

The purpose of this research is to design a PID control on a DC motor using 2 tuning methods, namely Trial & Error and Ziegler-Nichols. The results showed that the Pittman DC Motor system response from the Pittman DC motor was very unstable, in which there were still many oscillations and a very high overshoot value. In the Trial & Error method, the system response value was obtained on the P controller, namely, rise time = 0.000551 s, settling time = 0.00468 s, overshoot = 37.1 %, peak time = 0.972 s, and time delay = 0.00134 s. on the PI controller namely, rise time = 0.000396 s, settling time = 0.00534 s, overshoot = 47.7%, peak time = 1.23 s, and time delay = 0.00102 s. on the PID controller namely, rise time = 0.000223 s, settling time = 0.00502 s, overshoot = 64.6%, peak time = 1.54 s, and time delay = 0.000601 s. In the Ziegler-NIchols method, the response value of the system to the P controller is obtained, namely, rise time = 0.00118 s, settling time = 0.00564 s, overshoot = 15.4%, peak time = 0.178 s, and time delay = 0.00262 s. on the PI controller namely, rise time = 0.000275 s, settling time = 0.00531 s, overshoot = 58.3%, peak time = 1.44 s, and time delay = 0.000767 s. on the PID controller, namely, rise time = 0.00133 s, settling time = 0.00446 s, overshoot = 12.6 %, peak time = 0.0237 s, and time delay = 0.00288 s. The simulation results show that the value for the Ziegler-Nichols tuning method is better than the Trial & Error method, perhaps because the input value for the Trial & Error method is larger.

The Vera C. Rubin Observatory is expected to start the Legacy Survey of Space and Time (LSST) in early to mid-2025. This multiband wide-field synoptic survey will transform our view of the solar system, with the discovery and monitoring of over five million small bodies. The final survey strategy chosen for LSST has direct implications on the discoverability and characterization of solar system minor planets and passing interstellar objects. Creating an inventory of the solar system is one of the four main LSST science drivers. The LSST observing cadence is a complex optimization problem that must balance the priorities and needs of all the key LSST science areas. To design the best LSST survey strategy, a series of operation simulations using the Rubin Observatory scheduler have been generated to explore the various options for tuning observing parameters and prioritizations. We explore the impact of the various simulated LSST observing strategies on studying the solar system’s small body reservoirs. We examine what are the best observing scenarios and review what are the important considerations for maximizing LSST solar system science. In general, most of the LSST cadence simulations produce ±5% or less variations in our chosen key metrics, but a subset of the simulations significantly hinder science returns with much larger losses in the discovery and light-curve metrics.

Carbon monoxide (CO) is predicted to be the dominant carbon-bearing molecule in giant planet atmospheres and, along with water, is important for discerning the oxygen and therefore carbon-to-oxygen ratio of these planets. The fundamental absorption mode of CO has a broad, double-branched structure composed of many individual absorption lines from 4.3 to 5.1 μm, which can now be spectroscopically measured with JWST. Here we present a technique for detecting the rotational sub-band structure of CO at medium resolution with the NIRSpec G395H instrument. We use a single transit observation of the hot Jupiter WASP-39b from the JWST Transiting Exoplanet Community Early Release Science (JTEC ERS) program at the native resolution of the instrument (R ∼ 2700) to resolve the CO absorption structure. We robustly detect absorption by CO, with an increase in transit depth of 264 ± 68 ppm, in agreement with the predicted CO contribution from the best-fit model at low resolution. This detection confirms our theoretical expectations that CO is the dominant carbon-bearing molecule in WASP-39b’s atmosphere and further supports the conclusions of low C/O and supersolar metallicities presented in the JTEC ERS papers for WASP-39b.
Multiple Channels for Nitrogen Pollution by Metal-enriched Supermassive Stars and Implications for GN-z11
Authors: Nagele Chris , Umeda Hideyuki
Published: May 2023

GN-z11 is an unusually luminous high-redshift galaxy that was recently observed to have strong nitrogen lines while at the same time lacking traditional signatures of active galactic nucleus activity. These observations have been interpreted as a supersolar nitrogen abundance, which is challenging to explain with standard stellar evolution and supernova enrichment. We present simulations of four models of metal-enriched supermassive stars after the zero age main sequence, which produce supersolar nitrogen consistent with the observations of GN-z11. We then show that the most-massive model ends its life in a violent explosion that results in even greater nitrogen pollution.

Published: May 2023

BACKGROUND: The coverage of infants who are exclusively breastfed in North Sulawesi Province is still low. One of the causes is the lack of knowledge and lack of support from health workers as well as the closest family. In this digital era 4.0, there is a need to utilize technology as a medium for health education and assistance. The use of technology makes it easier for the facilitator to send videos and audio containing extension materials and can be accessed and conduct discussion activities anytime and anywhere by respondents.

AIM: This study aims to analyze the success of exclusive breastfeeding for breastfeeding mothers who are given support in the form of assistance through the use of technology.

METHODS: The research design used is quasi-experimental group control pre- and post-test. The intervention group was given support through assistance using technology. The control group was given education using medial leaflets.

RESULTS: The results of the study were tested using the Mann–Whitney test. The mean score of the intervention group was 0.87, greater than the mean score of the control group of 0.33. P value is 0.000 < 0.05 so it can be concluded that the hypothesis is accepted.

CONCLUSION: The support provided through assistance to breastfeeding mothers by utilizing technology had an impact on the success of exclusive breastfeeding on 40 days of birth. It is recommended that service health providers pay attention to support for the success of exclusive breastfeeding, starting from pregnant women, during delivery, even during the period of breastfeeding.

For a tuple of $ k $ consecutive integers sorted in ascending order, denoted by $ T_k $, call $ T_k $ a nice $ k $-tuple if each integer of $ T_k $ is a sum of two powers of the form $ a^x+y^b $ and a perfect $ k $-tuple if each integer of $ T_k $ is a sum of two perfect powers of the form $ a^x+y^b $, respectively. Let $ N_k(a, b) $ be the number of nice $ k $-tuples and $ \widetilde{N}_k(a, b) $ be the number of perfect $ k $-tuples. For a given $ (a, b) $, it is quite interesting to find out $ N_k(a, b) $ and $ \widetilde{N}_k(a, b) $. In 2020, Lin and Cheng obtained the formula for $ N_k(2, 2) $. The main goal of this paper is to establish the formulas for $ N_k(a, b) $ and $ \widetilde{N}_k(a, b) $. Actually, by using the method of modulo coverage together with some elementary techniques, the formulas for $ \widetilde{N}_k(2, 2) $, $ \widetilde{N}_k(3, 2) $ and $ N_k(3, 2) $ are derived.

Since its debut in the field of education nearly three decades ago, Artificial Intelligence (AI) has been considered as a powerful tool to facilitate new paradigms for instructional design and innovative educational practice in the form of intelligent tutoring systems, chatbots, teaching robots and adaptive learning systems among others. Recent technological advances in the adjacent areas of natural language processing, machine learning and computer graphics focusing primarily on design features that can improve their human-like qualities of naturalness and believability as human interlocutors have also amplified new application opportunities for Intelligent Virtual Agents (IVAs) or Animated Pedagogical Agents (APAs) within the area of Intelligent Computer-Assisted Language Learning (ICALL). Although AI-powered IVAs hold the potential to enhance the learning process in nearly any knowledge domain and personalize automation in teaching by embodying different roles in the learning environment, strikingly few studies have empirically attempted to assess IVAs impact on L2 learners’ academic achievement when learning English as a Foreign (EFL) so far. This study addresses this issue via a systematic review of relevant interventionist IVA studies that were conducted in EFL settings and published within the 2015-2020 timeframe examining IVAs key affordances, major barriers in their adoption for language learning purposes, and the CALL research trends currently prevalent on the topic. Pedagogical implications for the effective implementation of IVA technology in L2 contexts are discussed and future research avenues in the area are highlighted.

Practical Knowledge Level Characteristics and Innovative Practice Achievement Transformation Mechanism of Vocational College Students
Authors: Gao Zhenping
Published: May 2023

Cultivating talents with innovation ability is both the goal of higher vocational colleges and their responsibility given by the era. Focusing on improving the practical knowledge level of students means that students should be exposed to nature, society and problems through practical activities, thus providing the maximum space for them to think, explore, discover and innovate. As for existing studies on cultivating innovative ability of students and improving their practical knowledge level, they mainly have focused on ability evaluation and analysis of influencing factors, and few of them has involved analysis of their practical knowledge level characteristics. Therefore, this paper studied the characteristics and transformation mechanism of their innovative practice achievements. A multi-level comprehensive evaluation system was constructed, which aimed to evaluate the practical knowledge level of those students. The input dimension of quantized data of indexes was reduced in accordance with the principal component analysis (PCA). Then the quantized data of the low-dimensional indexes were mined by hierarchical clustering, and different training subsets were generated to participate in the evaluation model training. Based on the idea of clustering-prediction-integration, Gated Recurrent Unit (GRU) model was used for nonlinear integration of the output results of two-way Long Short-Term Memory (LSTM) model, which further fit the nonlinear characteristics in the quantized data of all indexes. By introducing Bootstrap-Data Envelopment Analysis (DEA) method, the transformation rate of innovative practice achievements of the students was collected and calculated in order to obtain a small calculation error. Experimental results verified the effectiveness of the proposed calculation method of the model.

Published: May 2023

Internationalisation of South African higher education has increased the cross-border migration of students from other African nations. However, South Africa's socio-economic and developmental challenges have given rise to resentment and intimidation of African foreign nationals in some communities, unintendedly impacting the well-being of African International Students (AIS) in South Africa's Higher Educational Institutions (HEIs). The chapter examines the effect of the “Noise and Actions” within South Africa on the psychological well-being of AIS. A qualitative and exploratory research approach was employed to analyse the perceptions of AIS in South Africa's HEIs. The study found that challenges affecting AIS are both external and internal. Amongst the external are cultural differences and xenophobia. The findings could be used to assist South African HEI management and policymakers to understand and develop programmes to improve AIS's well-being within their HEIs. The chapter contributes to the book on successful pathways for the well-being of Black students.

Schools are suitably located to provide learners with well-being and mental health services due to available skills and resources. The purpose of this literature study is to determine Lesotho school-going learners' well-being using the OECD well-being model. Google search was used to locate literature on learners' well-being and the provision of mental health in schools in Lesotho. Thematic data analysis was used to reveal ways in which Lesotho schools provide well-being. The results revealed that Basotho learners' well-being needs attention in all four dimensions. Learners do not have adequate food, some are HIV positive, while others are pregnant at an early age. Cognitively, Basotho learners were found to perform poorly compared to their counterparts in 14 English-speaking African countries. At the Junior Certificate level, Basotho learners countrywide do not perform well in Mathematics and Science. Socially, learners are beaten at school and at home. This study recommends that policies be developed and implemented to improve learners' well-being.

Many studies that focus on Black students examine risk factors and their link with negative outcomes. With societal existences such as racism, discrimination, and prejudice, Black students face challenges that can compromise their health and overall well-being. A series of subject-related keywords was used to extract potentially relevant articles and relevant texts from three electronic databases (Directory of Open Access Journals [DOAJ], Education Resources Information Center [ERIC], and Google Scholar). The findings show that there is a need for groundbreaking strategies involving promotion for reform school discipline practices.
Art in Memory
Authors: Biron Zachary
Published: May 2023

Art therapy is an effective method of treating behavioral and psychological issues in individuals with dementia and Alzheimer's disease, and has been tested amongst patients as early as the 1980s. Although similar benefits have been seen in populations of people who are not at risk for this disease, studies have shown art therapy to be effective at lowering levels of depression, improving social skills, supplementing verbal communication, enhancing quality of life, and maintaining fine motor skills in participants with dementia and Alzheimer's disease. Additionally, some research has suggested that art therapy may play a role in improving cognition, delaying neuronal decay, and inspiring autobiographical memories, though further research is needed to support these arguments. This chapter will dissect the many studies that suggest various cognitive and psychological benefits, analyze current interventions, examine art's role in a therapeutic setting, and advocate for future studies.

Authors: Kroesche Heather
Published: May 2023

Eating disorders impact a large number of individuals worldwide. Due to a rise in media standards on weight and appearance, prevalence rates of eating disorders are at an incline. Diagnoses include anorexia nervosa, bulimia nervosa, binge eating disorder, and emotional eating. Research in dance movement therapy as treatment for eating disorders suggest that dance movements' creative and physical attributes can positively affect individuals' recoveries from eating disorders as increased body-image satisfaction, self-awareness, and body awareness occurs. Dance movement therapy offers a range of intervention styles that can be tailored through individual therapy or be used to build community in group therapy. Additionally, different intervention designs tackle a myriad of components that plague eating disordered individuals such as attachment style, emotional distress response, and the mind-body connection. Dance movement therapy's treatment has a prominent focus on the therapist/patient relationship, development of physical practice and confidence, and personal reflection.
