Published: November 2024

Many elementary school students have low conceptual understanding, it is because students do not absorb learning well, and one of the factors is the lack of learning media. Therefore, it is necessary to use more interactive learning media such as animated video media. This study aims to determine the effect of animated video media on students' understanding of science concepts. This research was conducted at SDN Kebon Besar 1. The method applied in this study is quantitative in the form of quasi-experiments. The population of this study was all grade IV students totaling 56 students, which were divided into two (2), namely class IVA as a control class using conventional learning methods and class IVB as an experimental class using animated videos. The data collection technique was in the form of a test (pretest-posttest). Hypothesis testing carried out with a t-test on the posttest test with a significance level of ? = 0.05 found Sig. (2-tailed) = 0.000 which means H0 is rejected and H1 is accepted. It can be concluded that animated video media has an effect on students' understanding of science concepts.

A new heterometallic complex of CoII and NdIII with phenathroline [Co(Рhen)3][Nd(NO3)5(H2O)][Nd(NO3)4(H2O)2]H2O was synthesized for the first time by the self-assembly method. The crystal structure of the complex was determined by X-ray crystallography. The compound is an anion-cation complex and crystallizes in the monoclinic space group P21/n with unit cell parameters a=12.4251(4) Å, b=11.7206(3) Å, c=36.5374(12) Å, ==900, =90.581(3)0. In the crystalline phase, the complex is in the form of a crystal hydrate with a composition of 1:1. The anionic part of the complex consists of two nitrate hydrated NdIII complexes: [Nd(NO3)5(H2O)]2– and [Nd(NO3)4(H2O)2]–, in which the coordination number of neodymium is 11 and 10, respectively. The [Co(Phen)3]3+ ion is a cationic part of the complex in which the CoII atom has a distorted CoN6 octahedral environment, bidentately coordinating three phenanthroline molecules. Due to intermolecular hydrogen bonds (N–HO, O–HO), a three-dimensional supramolecular architecture is formed in the crystal, in which the polymer layers are packed parallel along the crystallographic axis a.

This study investigates a simple approach for synthesizing gold nanoparticles (Au NPs) using atmospheric pressure plasma without the need for reducing agents, additives, or capping agents. The size, morphology, optical properties, and aggregation stability of the synthesized Au NPs were characterized using scanning electron microscopy, UV-vis spectroscopy, and zeta potential analysis. The UV-vis absorption spectra of the gold nanoparticles, obtained at various Au3+ concentrations and treatment durations with anode plasma discharge, were analyzed. The UV-vis spectra revealed a surface plasmon resonance absorption band between 530–600 nm, indicative of Au NP formation. Results demonstrated that the size of Au NPs can be tuned within the range of 30–75 nm by adjusting the gold salt precursor concentration from 0.3 to 2.5 mmol/L. It was found that plasma treatment for 3–10 minutes, at different Au3+ concentrations, resulted in the formation of Au NPs with varying sizes and morphologies. The study showed that particles with different shapes – spherical, hexagonal, and triangular – were formed depending on the initial concentration of Au3+. The plasma-chemically synthesized nanoparticles at an Au3+ concentration of 0.06 mmol/L were predominantly spherical and exhibited the highest stability (lasting 12–24 hours), with a zeta potential of –20 to –22 mV, compared to samples with Au3+ concentrations ranging from 0.3 to 2.5 mmol/L.

Published: November 2024

In solutions of N-[arylsulfonylimino(methyl)methyl]-1,4-benzoquinonemonoimines, several Z,E-isomerization processes occur simultaneously: a fast inversion isomerization process (topomerization) relative to the C=N1 quinoneimine bond; a slow inversion isomerization process relative to the C=N2 exocyclic bond; and a process of inhibited rotation around the =N1–С= bond that connects two imine fragments. In the 1H NMR spectra, isomerization with respect to the C=N2 exocyclic bond was only detected. The theoretical values of the isomerization barriers for the C=N1 and C=N2 bonds, as well as for the inhibited rotation around the =N1–C= bond were determined, along with the experimental Z,E-isomerization barriers for to the C=N2 bond. It was established that in the 1H NMR spectra for N-[arylsulfonylimino(methyl)methyl]-1,4-benzoquinonemonoimines, only Z, E-isomerization relative to the C=N2 bond can be observed.

The mechanical properties of composite ceramic materials obtained based on oxygen-free silicon compounds are largely determined by the properties of the glass binder. This paper presents the results of studies aimed at determining the most fusible glass in the pseudo-binary system 2MgO2Al2O35SiO2–2MnO2Al2O35SiO2 with a high tendency to crystallize as a glass-ceramic binder for low-temperature sintering of high-strength ceramic materials based on oxygen-free silicon compounds. The crystallization tendency of the experimental melts decreases with an increase in in the content of manganese cordierite, as confirmed by X-ray and infrared spectroscopic studies. Based on experimental studies, a melting diagram was constructed, which was used to determine the ratio between magnesium cordierite and manganese cordierite (50:50 wt.%), ensuring a minimum melt temperature of 12750C. The melting point of the glass of the specified composition is 14500C. The synthesized glass is characterized by a softening point of 8000C and crystallizes intensively at 10300C. The The thermal coefficient of linear expansion of the crystallized glass samples is 20.810–7 0C–1. X-ray diffraction and electron microscopic studies have shown that the developed glass is almost completely crystallized during heat treatment for 2 hours, forming a cordierite solid solution 2(Mg,Mn)O2Al2O35SiO2. The size of the cordierite phase crystals ranges from 0.5 to 3.0 m. Due to its fusibility and high crystallization tendency, the developed glass, can be proposed as a promising glass-ceramic binder for the production of high-strength ceramic materials (wear and impact resistant) based on SiC and Si3N4 with reduced sintering temperatures.

A new method of processing polyethylene terephthalate waste into a highly dispersed polymer filler by chemical treatment in an aqueous ammonia solution has been proposed. The possibility of obtaining highly dispersed polymer filler and polymer composite materials under elevated pressure and temperature by incorporating the filler into an epoxy oligomer has been demonstrated. The size and microphase structure of dispersed modified polyethylene terephthalate were determined using optical microscopy and speckle interferometry. Infrared spectroscopy established the presence of polyamide groups on the surface and preserved polyethylene terephthalate in the center of the particles. The use of 2-(tri-butoxymethyl)oxirane monoepoxide demonstrated that the resulting powder is an active filler and reacts with epoxy groups at elevated temperature, enhancing the strength of the composite after formation. Some operational characteristics of the polymer composites have been determined, and the feasibility of applying the proposed methods to address the disposal of PET containers, including plastic bottles, has been shown. The conditions for producing the fillers, along with the characteristics of the obtained fillers and the polymer composites based on them, have been established.

Досліджено особливості розмежування Європи відносно інших частин світу задля її ідентифікації, як територіально-акваторіального підрозділу регіонального рівня планети й основи в системі ієрархічної супідрядності просторово-територіальних окремостей (елементів, підрозділів) планетарного та регіонального рівнів. Дослідження ґрунтується на комплексному використанні загальнонаукових і спеціально-наукових методів. Зокрема, для встановлення регіональних особливостей еволюції проблематики межування Європи застосовано низку методів (ретроспективний, хронологічний, періодизації, порівняльно-географічний, історико-географічний, діалектичний й структурно-функціональний) та підходів (геопросторового планетарного, блочно-ієрархічного, індивідуального, типологічного та ін.). Вичленовування цілісних територіальних систем рівня частини світу базується на ландшафтно-генетичному принципі, методі типологічного районування, картографічного моделювання, принципі природно-антропогенної сумісності. Узагальнено й систематизовано досвід проведення меж Європи як своєрідного територіально-акваторіального простору Землі. Виявлено проблеми маркування меж Європи та запропоновано свої пропозиції щодо їх вирішення через висвітлення методологічних підходів та відповідного представлення результатів межування з примежовими орієнтирами. Встановлено межу – зовнішній контур, що відокремлює Європу від решти частин світу. Таке картографічне відображення меж Європи загалом формує уяву про локалізацію цієї частини світу на земноводній поверхні планети та є сукупним відтворенням просторово-часової організації земних реалій і соціального досвіду розвитку геосередовища. Використання Європи як географічної проекції на поверхні Землі закладає передумови для узгодженого, стандартного групування держав за регіонами з чітким територіально-акваторіальним охопленням і характеристиками (площа, відстань тощо) передусім у науково-освітньому просторі. Уточнення й перспективна стандартизація кордонів Європи буде сприяти узгодженню матеріалів у підручниках і посібниках із географії, історії, культурології, політології, довідкової літератури, енциклопедії, карт атласів тощо.

Порушення функціонування гепатобіліарної системи, внаслідок холецистектомії, викликає певну симптоматику, з якою пацієнти звертаються за медичною допомогою. Досить часто пацієнти відчувають біль, диспепсію, яка проявляється нудотою, метеоризмом та діареєю, це в свою чергу веде до психологічного дискомфорту та підвищеної тривожності, що позначається на активності та участі пацієнта та його соціальних зв'язках і якості життя. Метою дослідження було оцінити динаміку порушення функції та структури організму в пацієнтів після холецистектомії за кваліфікатором МКФ під впливом програми фізичної реабілітації. В дослідженні взяли участь 46 осіб, (12 чоловіків та 34 жінок), вік обстежених коливався в середньому від 25 до 60 років. Обстежені методом рандомізації в амбулаторних умовах поділені на дві групи: контрольну групу (КГ), особи якої приймали тільки медикаментозні засоби (n=20), а основна група (ОГ), займалася гідрокінезі-терапією та отримувала медикаментозне лікування (n=26). При оцінюванні враховувалася біопсихосоціальна модель на основі Міжнародної класифікації функціонування, обмежень життєдіяльності та здоров’я (МКФ). Відповідно до МКФ за доменом b оцінювали порушення функції травної системи; за доменом s ураження структури травної системи. Фізичну реабілітацію проводили із застосуванням гідрокінезіотерапії 3 місяці 2 рази в тиждень з помірною інтенсивністю та тривалістю 40 хвилин. Дослідженням було доведено, що програма фізичної реабілітації із застосуванням гідрокінезіотерапії чинить позитивну динаміку функціонування за доменами МКФ та покращує активність та участь пацієнтів в повсякденному житті (р<0,001, р<0,01) на противагу звичайному медикаментозному лікуванню.

Published: November 2024

ABSTRACT
Objective: Oreochromis niloticus (Tilapia) meal was evaluated as a source of nutrients in agriculture, through a composting process mixed with a zero tillage soil.
Design/methodology/approach: Two manures were formulated, mixing flour and soil at a 30:70 ratio (mass/mass w:w) respectively. Compost A was maintained at 60 days of composting (ddc), compost B at 30 days. The phytotoxicity of the manures was evaluated as percentage of germination in Solanum lycopersicum (tomato) seeds.
Results: The N-P-K ratio (% dry mass) was 1.90-2.06-0.30 for manure A (60 ddc), and 2.60-2.24-0.34 for B (30 ddc). On germination, 100% concentration; manure A had 44.9% and B 19.6%, compared to the control. For concentration of 10% it was 93.7 and 111.4%, manure  A and B, respectively.
Limitations on study/implications: It is necessary to carry out more phytotoxicity tests. In this experiment, dilutions were made in the manures to increase germination.
Findings/conclusions: The use of manure based on tilapia meal in agriculture is proposed in the future and in this way take advantage of the waste from fish processing.
Keywords: Fish meal, compost, tomato, soil improver
The Deadly Trio: Do warming, acidification & deoxygenation destabilize the anemone-algae symbiosis?
Authors: Parodi Bianca , Stanca Ioana , Burgués Palau Laia , Qin Zhen , Laetz Elise
Published: November 2024

Anthropogenic climate change is primarily driven by carbon dioxide release, which causes a domino effect of warming, acidification, and hypoxia in aquatic habitats. Using a fully-crossed experimental design, we investigated how exposure to this “deadly trio” of environmental stressors affects the sea anemone, Exaiptasia diaphana and its endosymbiotic dinoflagellates. To mimic conditions found on tropical reefs, we cycled hypoxic treatments between high oxygen saturation during the day (100 %) and hypoxia (40 %) at night. We increased ocean warming and acidification treatments to 30 °C and 7.7 pH in accordance with the “worst case” predictions in the IPCC 2023 report. After exposure for two weeks, we measured each anemone’s metabolic rate, thermal tolerance, and heat tolerance plasticity. We also assessed algal density and photosynthetic efficiency, both of which remained consistent across all treatments, indicating negligible stress levels and a healthy symbiosis. Interestingly, metabolic depression was observed in anemones exposed to the deadly trio, which is likely an energy conservation strategy due to its co-occurrence with increased thermal tolerance. Furthermore, we found an interaction between ocean acidification and nightly hypoxia as combined exposure improved heat tolerance plasticity, potentially because increased carbon dioxide enhanced photosynthetic activity. We therefore conclude that E. diaphana will survive short-term exposure to the “worst case” levels of deadly trio stressors. To verify this interpretation, we determined their acute stress tolerance, finding that they can withstand termporary exposure to more than 34 °C seawater, a minimum pH of 6.01 and anoxia for more than 4 days. These conditions greatly exceed worst-case predictions, confirming that this species should survive acute exposure to the deadly trio, potentially due to their symbiosis. These findings highlight the importance of considering all three stressors in climate change ecophysiological studies.
Arabica Coffee Bean Growing in the Chiang Rai and Chiang Mai Areas of Northern Thailand and How to Make the Farming More Sustainable
Authors: Mark Azavedo
Published: November 2024

The problem statement for this study was how to improve the sustainability of the Arabica coffee bean growing industry in Chiang Rai and Chiang Mai in Northern Thailand. The focus from that was how to improve the quality of the beans to optimise sale price whilst also maximising yield to optimise income. Another issue arises, particularly in the era of global warming and increased environmental concern, which is embracing commercial imperatives whilst also being environmentally friendly. To that extent a general toolkit of actions can be proposed for the production process but concurrently seeking not simply to sustain the Arabica industry but the whole local environment, its flora and fauna and farming and other families. The final question then becomes how relevant general concepts are in specific local areas of particular terroir (simplifying, soil, climate and topography, particularly altitude) and how adaptive they need to be not only in terms of the geophysical environment but also the human environment and its traditions. Detailed testimony was received from local farmers.

Мета статті – виявити функційний зв’язок з літературою та особливості використання рамкових побудов у поетиці фільмів П. П. Пазоліні, а також окреслити їх смислоутворювальний потенціал. Застосовано переважно структурно-семіотичний метод, який є спільною основою розвідок поетики як літератури, так і кінематографу, адже актуалізує бачення фільму як тексту, а кінематографу – як однієї з численних мов мистецтва. В результаті виявлено семантичну активізацію рамкових позатекстових елементів (назв, епіграфів, титрів) у всіх кінотворах Пазоліні, їх смислове навантаження і роль у створенні парадигмальних, нелінійних та наближених до поетичних смислових структур. Також проаналізовано смислове навантаження обрамлення як композиційного принципу у більшості фільмів митця та метафоричні, асоціативно-поетичні, сугестивні смисли композиційної рамкової побудови «тексту в тексті» у його фільмах із подвійним хронотопом («Птахи великі та маленькі», «Цар Едіп», «Свинарник», «Сало, або 120 днів Содому»). Окремо на матеріалі фільму «Євангеліє від Матфея» проаналізовано смисловий потенціал та поетикальні особливості такого суто кінематографічного рамкового елемента, як рамка кадру. В підсумку зроблено висновок про не наративний, а асоціативно-метафоричний та інтелектуально-аналітичний характер тих художніх завдань, які вирішує Пазоліні за допомогою всіх різновидів обрамлення, що дає змогу вважати рамкові побудови у його фільмах елементами індивідуальної поетичної кіномови, у відповідності до того розуміння поетичного кіно, яке Пазоліні пропонував у своїх теоретичних працях.

Human activities and natural events continually reshape land use patterns, underscoring the critical need for accurate land use information in various applications such as natural resource management and environmental monitoring. Land use change has become pivotal in current strategies for these purposes globally. The rapid advancements in land use mapping have spurred increased studies worldwide, aiming to assess and monitor the extent and health of forests, grasslands, and agricultural lands. Remotely sensed data, including aerial photographs and satellite imagery, are indispensable for extracting precise land use change information. This study focusing on Manga grassland (Machina, Yusufari, and Yunusari LGAs), satellite images from Landsat TM (1988), Landsat ETM (1998), Landsat ETM+ (2008), and Landsat 8 (2018) for image classification. The study employed supervised classification methods to analyse land use changes, revealing significant alterations in vegetation cover over the study period. In conclusion, it was observed that observed that vegetation cover increases from north toward the south follow the trend of rain fall, over-cutting, over grazing, and other climatic factors, which determines species distribution.  Vegetation degradation is detected more in north boundary Niger republic. This may be due to southern flow of the Sahara Desert into the northern part of Nigeria around the study area. Data analysis shows that land use land cover had been changing through the study zones and this change had negative impact on natural resource development. Finally, it was recommended that the development of suitable and adequate mean of awareness for local community on the importance of species...

Published: November 2024

The study explored present and future climate scenarios of Kano using Global Circulation Models (GCMs). The metrological data from 12 locations were used for calibration of Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS).  The historical record of 10 years was used for both temperatures and rainfall data which represent a period of 2010 to 2019. The future climate projections were made for 2041 to 2060 centered in the 2050s under RCP2.6 and RCP8.5 emission scenarios. The spatial analysis was conducted using the Inverse Distance Weighted (IDW) tool in an ArcGIS environment. The result shows that the temperature of Kano has increased relative to baseline condition by 1.025oC (2.45%) and 4.6 oC (10.98%) under RCP2.6 and RCP8.5 scenarios respectively. However, the annual rainfall was found to decrease from the historical amount by -37.9 mm (5%), and -68.2 mm (9%) under RCP2.6 and RCP8.5 emission scenarios. Moreover, the spatial analysis indicated that there was climate variability across the width and breadth of the state. The study concludes that the climate change effect will cause the temperature of Kano to rise considerably in the future with the consequences of decreased rainfall amount. The findings recommend that policymakers should deploy adaptation strategies to reduce the adverse effects that might be experienced.

Published: November 2024

This study investigates various epidemiological aspects of Hepatitis C infection by employing a fractional-order mathematical model to evaluate the impact of treatment on the transmission dynamics of the disease. The research identifies conditions for the existence and uniqueness of the solution in the fractional-order case and conducts a stability analysis of the endemic equilibrium using the Lyapunov function method. Numerical simulations, performed using the fractional Adams–Bashforth–Moulton technique, demonstrate the effects of model parameters and fractional-order values on the control and spread of Hepatitis C. Further simulations with surface and contour plots reveal that higher contact rates and reduced treatment effectiveness lead to an increased prevalence of Hepatitis C. The study also concludes that optimizing treatment strategies can significantly decrease the disease's prevalence in the population.

Published: November 2024

PLN Nusantara Power UP Tenayan is a coal-fired power plant supplying electricity to the Riau region with a capacity of 2 x 110 MW. Operating 24/7, the plant faces frequent failures, particularly in the instrumentation components of the coal feeder. This research employs the Failure Mode and Effect Analysis (FMEA) method to identify and analyze these failures. The Risk Priority Number (RPN), calculated by multiplying severity, occurrence, and detection ratings, helps determine the failure level. Research stages include a preliminary study, problem identification, observations and interviews, data collection and processing, FMEA analysis, and conclusion drawing. The results indicate that the instrumentation components are generally reliable, with RPN values below the critical threshold of 200. The speed sensor, with the highest RPN value of 160, is still categorized as reliable. Failures in these components can lead to operational failures, suboptimal coal feeder performance, and monitoring difficulties. The study recommends preventive maintenance every six months to enhance reliability and minimize disruptions.

Published: November 2024

One of the observation facilities available in Indonesia was Automatic Dependent Surveillance-Broadcast (ADS-B), a surveillance technology similar to Radio Detection and Ranging for monitoring air traffic. This system only received information transmissions from aircraft, broadcast on a frequency of 1090 MHz using a monopole antenna with large dimensions, ranging from 85 centimeters to 3,5 meters, and weighing between 1,5 kilograms to 26 kilograms. As an alternative, a microstrip antenna was chosen to reduce the large size and weight of the monopole antenna. This research aimed to design a 2x1 rectangular patch microstrip array antenna with a proximity coupled feeding method at a frequency of 1090 MHz. The antenna was designed using Antenna Design Software and fabricated using Epoxy substrate material with a copper ground plane. The simulation results showed a Return Loss of -28,87 decibels, VSWR 1,07, Bandwidth 28,87 MHz, Impedance 52,4 Ω, and Gain 8,49 decibels. The measurement results showed a Return Loss of -30,87 decibels, VSWR 1,07, Bandwidth 28 MHz, Impedance 48,91 Ω, and Gain 6,4 decibels. The test results demonstrated that the antenna successfully received signals from 32 aircraft, with the longest reception distance reaching 172,5 Nautical Miles (319.4 kilometer) at a maximum altitude of 36,950 feet.

The potential of solar energy is very large in generating electrical energy conversion using TEG and PV technology. Therefore, it is important to understand how the technology works. This study aims to characterize the electrical generation of 12 TEG modules type TEC1-12706 hybridized with 2 PV panels. One PV panel is left without a TEG module as a comparison. Meanwhile, on the cold side of the TEG attached to the PV, a heatsink with 3 fins is placed. The left and right fins are air allowed to flow naturally, while the middle fin is flowed with cold water fluid through a 0.01 m diameter water hose with 2 flow rates; 0.02 and 0.05 m / s. The results of the study showed that the fluid flow rate of 0.02 presented a better TEG performance effect than 0.05 m / s at an irradiance of 450 W/m2. Different things are shown by PV solar panels, where the power generation and efficiency are better in TEG at a flow rate of 0.05 m/s compared to 0.02 m/s for the same irradiance. Overall, the performance of PV-TEG is better at a TEG cooling fluid flow rate of 0.05 m/s.

Published: November 2024

The research developed a Submersible Pylon Inspection Robot (SPIR) to clean and inspect underwater structures automatically, facing challenges in stability and depth of operation. Integrating the Inertial Measurement Unit (IMU) with the Extended Kalman Filter (EKF), as well as implementing customized PID controls, aims to improve the accuracy and stability of SPIR in dynamic underwater environments. The results show that the SPIR control system can follow the reference depth at shallow depths well, but has difficulty maintaining stability at deeper depths. The position error graph on the Z-axis shows the initial fluctuation that decreases over time, reflecting the increased calibration. The use of drive motors also shows different working patterns, with some motors active in depth settings and others for stabilization. This study shows that the integration approach of IMU, EKF, and PID control can improve SPIR performance, although further adjustments are required to meet the extreme challenges in underwater environments.
