Lowering Cholesterol through Ethanol Extract and Nano-Symplasia of Takokak Fruit (Solanum torvum Swartz.): An In vivo Study

BACKGROUND: The human body needs antioxidants that can help protect the body from free radical attacks by reducing the negative impact of these compounds. Antioxidants function to overcome or neutralize free radicals so that it is hoped that by giving these antioxidants, the aging process is inhibited or at least slowed down and can prevent damage to the body from the emergence of degenerative diseases. AIM: The aim is to prove whether giving Takokak fruit ethanol extract, and nano-simplicia reduces blood cholesterol in hypercholesterolemic mice. METHODS: This research design is experimental with the randomized post-test-only control group approach. The benefits of Takokak as alternative medicine in preventing hypercholesterolemia by consuming Takokak fruit can be a daily food menu. RESULTS: The administration of nano Takokak fruit reduced cholesterol, Low-density lipoprotein (LDL), and increased high-density lipoprotein (HDL) levels in mice. Administration of nano is very effective at a dose of 450 mg. At the same time, the ethanol extract of Takokak fruit gave a significant difference in reducing cholesterol and LDL levels at a dose of 900 mg/kg BW and increasing HDL at a dose of 450 mg/kg BW. CONCLUSION: Giving ethanol extract and nano-simplicia Takokak fruit are effective in lowering cholesterol.

Factors Influencing the Utilization of Contraceptives among Adolescents in the Tamale Metropolis, Ghana

Background: Adolescents’ sexual and reproductive health is supreme to healthy living, and because the health of adolescents is important, it has compelled most countries across the globe to put up appropriate measures to meet their needs. Aims: The main aim of the study was to assess the factors influencing the utilization of contraceptives among adolescents in the Tamale Metropolis, Ghana. Methods: This study employed a community-based cross-sectional design. The study recruited 374 adolescents using the multi-stage sampling technique. Data were analyzed using SPSS version 25. A p-value < 0.05 was considered statistically significant. Results: The majority (92.8%) of the adolescents have heard about contraceptives. Half of the respondents had sex before, with only 29.4% reported to have used contraceptives in the past. Only 30.7% of the respondents felt the service providers were friendly to them, the majority (60.2%) of the study participants felt that the health practitioners did not respect their privacy during their visit. Over half (51.1%) of the respondents were unsatisfied with the location where contraceptive services are rendered. The majority (82.9%) of the study participants cannot discuss contraceptives issues freely with their parents. The study established a significant association between usage of contraceptives and age (P<0.001), level of education (P<0.001), and marital status (P<0.001). Conclusion: The majority of respondents were sexually active, although contraception use was low in comparison to the teens' high awareness level. Factors such as poor attitudes of health practitioners, poor accessibility and availability of contraceptives, and lack of parental concern have to be addressed by key stakeholders’ engagement to holistically address adolescents’ sexual and reproductive health concerns in the metropolis.
Mechanisms of Action of Non-Canonical ECF Sigma Factors

Extracytoplasmic function (ECF) sigma factors are subunits of the RNA polymerase specialized in activating the transcription of a subset of genes responding to a specific environmental condition. The signal-transduction pathways where they participate can be activated by diverse mechanisms. The most common mechanism involves the action of a membrane-bound anti-sigma factor, which sequesters the ECF sigma factor, and releases it after the stimulus is sensed. However, despite most of these systems following this canonical regulation, there are many ECF sigma factors exhibiting a non-canonical regulatory mechanism. In this review, we aim to provide an updated and comprehensive view of the different activation mechanisms known for non-canonical ECF sigma factors, detailing their inclusion to the different phylogenetic groups and describing the mechanisms of regulation of some of their representative members such as EcfG from Rhodobacter sphaeroides, showing a partner-switch mechanism; EcfP from Vibrio parahaemolyticus, with a phosphorylation-dependent mechanism; or CorE from Myxococcus xanthus, regulated by a metal-sensing C-terminal extension.
Cancer-Derived Extracellular Vesicles: Their Role in Sarcoma

Soft tissue sarcomas (STS) are rare malignancies with limited responses to anticancer therapy. Extracellular vesicles (EVs) are a heterogeneous group of bi-lipid layer sacs secreted by cells into extracellular space. Investigations of tumor-derived EVs have revealed their functional capabilities, including cell-to-cell communication and their impact on tumorigenesis, progression, and metastasis; however information on the roles of EVs in sarcoma is currently limited. In this review we investigate the role of various EV cargos in sarcoma and the mechanisms by which those cargos can affect the recipient cell phenotype and the aggressivity of the tumor itself. The study of EVs in sarcoma may help establish novel therapeutic approaches that target specific sarcoma subtypes or biologies, thereby improving sarcoma therapeutics in the future.
Chatmate (Arcanetales 2.0): A Novel Warrioric Rpg Tool to Teach English Simple Information Communication

Gamification has emerged as the most compelling technology advancements in the field of human betrothment and has notably been adopted in the English education sphere. Learners who are learning English as a second language (ESL) face challenges communicating simple information which potentially jeopardizes learning. Previous research has revealed that gamified tools used within ESL acquisition are still predominantly emphasised on quizzes. There is a scarcity of studies examining the choice-based role-playing games (RPGs) for ESL learners in enhancing simple information communication at the primary level. Consequently, Chatmate (Arcanetales 2.0), a novel warrioric role-playing game (RPG) that integrates simple information communication as a core feature was innovated. Thus, this study attempted to investigate the effectiveness of Chatmate (Arcanetales 2.0) in reinforcing ESL learners' skill and increasing learners’ motivation in communicating simple information. A total of 20 Year 1 participants from a primary school in Negeri Sembilan, Malaysia, enrolled in this study. Data obtained using a closed-ended items questionnaire as part of a survey research method and discussed quantitatively in descriptive analysis. Findings revealed that Chatmate (Arcanetales 2.0) had a significant impact on learners through a fun learning environment, making learners motivated to communicate. Future research is recommended to broaden the application of Chatmate (Arcanetales 2.0) to teach a variety of language skills.

Investigation of microcrystalline silicon emitters and DC sputtered ZnO:Al as front contact in silicon heterojunction solar cells

Silicon heterjunction (SHJ) solar cells consisting of silicon thin film layers and crystalline silicon has the advantage of high open circuit voltage and hence higher efficiency compared to the traditional diffused solar cells. This structure needs transparent conductive oxide (TCO) for carriers transport to the metal grid. The main focus of this work is to investigate microcrystalline silicon (µc-Si:H) films as a novel emitter layer in combination with DC sputtered aluminum doped zinc oxide (ZnO:Al) as an alternative TCO for SHJ solar cells. The effect of ZnO:Al deposition parameters on the electrical properties of fabricated SHJ solar cells and an optimum deposition window for each process parameter to satisfy the TCO requirements were investigated. Moreover, several advantages of µc-Si:H emitter used to suppress the Schottky barrier at ZnO:Al/emitter interface such as improved passivation at emitter/c-Si interface and reduced emitter parasitic absorption were addressed.
An implementation of an artifact for security in 5G networks using deep learning methods

The Fifth-Generation networks are vital in telecommunications, which reaches a substantial increase in transmission speed. However, due to this dynamism, cyber attackers try to take advantage of certain configuration flaws. Under this problem, this study aims to design and implement an artifact capable of protecting and improving security in this cellular network type. The artifact uses a neural network structure based on Depp Learning, Gödel's theorem, Dijkstra's graph theory, a sigmoid function for faster activation in the designed neural network, and a mathematical model able to perform a recursive and logical process for the analysis of attacks. Considering the Gödel method, this artifact can evade Worms, Ransomware, Phishing, Doxing attacks and can be used in the OPC, Profibus, EtherCat, Profinet DNP3, and Modbus protocols. Its implementation allows us to create evasive actions in case of an attack and improve the configuring flaws in the security protocols, changing its parameters and making it secure. We developed the artifact through Extreme Programing with the combination of Python and Matlab. The results prove the functionality of the algorithms and demonstrate the success in evading an attack or making the best decision to protect the 5G network.

A Novel Topology for Solar PV Inverter Based on an LLC Resonant Converter With Optimal Frequency and Phase-Shift Control

In this article, a new topology for a grid-connected solar photovoltaic inverter for the direct connection to the medium-voltage grid is proposed. This topology employs an LLC resonant converter with a high-frequency (HF) isolation transformer in the dc–dc stage. The output of the dc–dc stage is a rectified sine wave voltage and current at the line frequency. An unfolder inverter interfaces between this dc stage and the grid. A combined phase-shift and frequency control method is used to control the LLC resonant converter. The phase-shift angle and switching frequency values of the LLC resonant converter are regulated to track the reference current signal for the whole operation range. The Lagrange multiplier method is applied to find the optimal trajectory to calculate the optimal phase-shift angle and switching frequency pairs for any operation condition by considering power converter and HF transformer losses to achieve the highest efficiency at a varying current. The transformer leakage and magnetization inductances are properly designed to provide a zero-voltage switching (ZVS) for a wide operation area, and additional resonant inductor requirement is removed. The LLC converter operates in a ZVS region except in a narrow band around the zero-current crossings of the inverter output. Using an HF transformer in the LLC resonant converter, a bulky line frequency transformer requirement is eliminated, and thus, a more compact and efficient design is obtained. The proposed topology is validated by the simulation and experimental results.

In this letter, a wideband three-dimensional (3-D) isotropic antenna is proposed with improved 3 dB coverage ratio. Based on the investigation about the effect of the metallic ground size on isotropic radiation, a compact sequential-phase feeding network made of lumped components with miniaturized ground is elaborately designed for wide operating bandwidth and enhanced 3 dB coverage ratio in 3-D space. In the measurement, the antenna prototype is with the size of 70 × 70 × 0.5 mm3 (0.23 × 0.23 × 0.0017 λ03). The measured result shows that the proposed antenna provides the 6 dB gain variation fractional bandwidth of 4% and the 3 dB coverage ratio of more than 80%, leading to promising usage for wideband isotropic radiation applications.

Effects of games in STEM education: a meta-analysis on the moderating role of student background characteristics

ABSTRACT Game-based learning has proven to be effective and is widely used in science education, but usually the heterogeneity of the student population is being overlooked. To examine the differential effects of game interventions in STEM (Science, Technology, Engineering and Mathematics) related subjects on diverse student groups, a meta-analysis has been conducted that included 39 studies that compared game-based learning interventions with traditional classrooms in primary and early secondary education. We found moderate positive effects on cognition (g = .67), motivation (g = .51), and behaviour (g = .93). Additionally, substantial heterogeneity between studies was found. Moderator analyses indicated that primary school students achieve higher learning outcomes and experience game interventions as more motivating than secondary school students, whereas gender did not have any moderating effect. There were too few studies reporting information on the remaining moderators (socioeconomic status, migration background, and special educational needs) to include them in a multiple meta-regression model. Therefore, we assessed their role by separate moderator analyses, but these results need to be interpreted with caution. Additional descriptive analyses suggested that game-based learning may be less beneficial for students with low socioeconomic status compared to students with high socioeconomic status.
A non-volatile flip-flop based on diode-selected PCM for ultra-low power systems

As the process technology is continuously shrinking, low power consumption is a major issue in VLSI Systems-on-Chip (SoCs), especially for standby-power-critical applications. Recently, the emerging CMOS-compatible non-volatile memories (NVMs), such as Phase Change Memory (PCM), have been used as on-chip storage elements, which can obtain non-volatile processing, nearly-zero standby power and instant-on capability. PCM has been considered as the best candidate for the next generation of NVMs for its low cost, high density and high resistance transformation ratio. In this paper, for the first time, we present a diode-selected PCM based non-volatile flip-flop (NVFF) which is optimized for better power consumption and process variation tolerance. With dual trench isolation process, the diode-selected PCM realizes ultra small area, which is very suitable for multi-context configuration and large scale flip-flops matrix. Since the MOS-selected PCM is hard to shrink further due to large amount of PCM write current, the proposed NVFF achieves higher power efficiency without loss of current driving capability. Using the 40nm manufacturing process, the area of the cell (1D1R) is as small as 0.016 μm2. Simulation results show that the energy consumption during the recall operation is 62 fJ with 1.1 standard supply voltage, which is reduced by 54.9% compared to the previous 2T2R based NVFF. When the supply voltage reduces to 0.7 V, the recall energy is as low as 17 fJ. With the great advantages in cell size and energy, the proposed diode-selected NVFF is very applicable and cost-effective for ULP systems.
Modeling and Analysis of Postdisaster Aviation Medical Rescue Process Using SPN-MC

Analyzing the time characteristics of the aviation medical rescue process after sudden natural disasters is an extremely important guarantee for efficient rescue. In view of the problem of the significant increase in the complexity and uncertainty of the postdisaster aviation medical rescue process under time constraints, this study sorted out and analyzed the postdisaster aviation medical rescue process. The dynamic discrete modeling of the postdisaster aviation medical rescue process was carried out in combination with the stochastic Petri net (SPN) theory, and the effectiveness of the process of postdisaster aviation medical rescue was analyzed by using the isomorphism relationship between SPN and Markov chain (MC). Finally, the Sichuan Jiuzhaigou Earthquake event was taken as a case study to carry out the performance analysis and sensitivity analysis of the postdisaster aviation medical rescue process model. The results showed that information accumulation tends to occur in the process of flight planning, flight preparation, flight information transmission, and field information feedback. On-site rescue, casualty transfer, preflight preparation, and personnel preparation take a relatively long time. In the actual rescue process, emergency decision-makers and rescue crews should focus on optimizing and improving these links. The route formulation and airspace application as the main factors affecting the operation time of the postdisaster aviation medical rescue process system should be used as the key to process optimization so as to improve the efficiency of postdisaster aviation medical rescue.
Sustainability reporting by companies: reasons and financial benefits

Sustainable development is one of the most promising concepts for the future of the society. Companies are an important participant in numerous social processes, and their sustainability is integral to the sustainability of the society. During the last three decades the number of companies preparing sustainability reports has increased. A lot of stakeholders and regulators pay already attention to this type of reporting. At the same time, there is а growing scientific interest in this field. Even though in recent years the number of regulatory acts that mandate certain companies to disclose environmental and social information has increased, the sustainability reporting is still mostly voluntary. This article attempts at summarizing and analyzing the causes that motivate companies to prepare a sustainability report, by reviewing existing literature and completed studies. A total of 14 main reasons have been found. Some of them are external, others are internal to the companies. The reasons may be economic, mainly related to the willingness of companies to improve the competitiveness of the company, but also non-economic, related to the value system of a top member of management or an owner, and the willingness to do good. All the reasons have been subsequently analyzed through the lens of the companies’ competitiveness.
