Published: May 2023

Developing confectionery products by reducing sugar and using natural ingredients is an important response to health-conscious consumers. In the present work, we determined how different concentrations of sucralose (SC)—0, 25, 50, 75, and 100%—as a replacement for sucrose while maintaining the same level of sweetness of rose tea gummy jelly (RTGJ) could affect the physical properties, reducing sugar content, total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity by DPPH method, sensory properties, and consumer attitude toward RTGJ. Results showed that the red colour (a* value) of 100% SC was the highest (p < 0.05). The hardness, gumminess, and chewiness values of 50% SC were the highest at a significant level (p < 0.05). The springiness and water activity of all samples were not significantly different (p > 0.05). Total reducing sugar content in the control sample was significantly higher (p < 0.05) than in other samples. The TPC and TFC of RTGJ were not significantly different (p > 0.05) among all samples, while antioxidant activity slightly decreased with increasing amount of SC in RTGJ. Remarkably, sensory analysis revealed no differences between the control sample and 100% SC, which had the highest liking scores in terms of sweetness, sourness, springiness, rose tea flavour, and overall liking. Consumers expressed that RTGJ with 100% SC could help them to relax and decrease tooth decay. The present work introduced a new functional jelly confectionery product using 100% SC and adding rose tea which showed potential for promoting phytochemical properties and enhancing emotional and health advantages.

The present work investigated the chemopreventive and immunoadjuvant properties of edible bird’s nest (EBN) extract on breast cancer cell line (MCF-7). Specifically, the cytotoxicity level of EBN extracts (HMG, EHMG, pHMG) against MCF-7, human immune cells of cytotoxic T cells, and monocytes (CD8+ and CD14+) were evaluated by measuring the production of pro-apoptotic and anti-apoptotic molecules released in single and co-culture of MCF-7, CD8+, and CD14+ cells, before and after EBN treatment. The highest cytotoxic effect towards MCF-7 using IC50 of 15 µg/mL was demonstrated by HMG but no effects on CD8+ and CD14+, with cell viability of more than 90%. At the mRNA level, activated CD8+ and CD14+ depicted increased pro-apoptotic gene expression after HMG treatment in co-culture. Additionally, HMG treatment increased apoptosis by down-regulating the regulation of anti-apoptotic genes and up-regulating the pro-apoptotic genes in MCF-7. ELISA and multiplex assay reflected increased pro-apoptotic factors, and decreased anti-apoptotic soluble factors, by non-activated and activated CD8+ and CD14+, in a single or co-culture with MCF-7 after HMG treatment. In conclusion, HMG extract possesses immunoadjuvant properties that can be a potential anticancer agent without causing any deleterious effects on the human immune cells.

Published: May 2023

Mycotoxins are natural toxins that consist of secondary metabolites produced by fungal species of Aspergillus, Fusarium, and Penicillium. The present work aimed to validate the analytical method for detecting multimycotoxins (aflatoxin B1, B2, G1, G2, fumonisin B1, B2, ochratoxin A, and zearalenone) in roasted coffee samples using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Eight stable 13C isotope-labelled internal standards were used for quantification, and an immunoaffinity column (IAC) was used for sample pre-treatment to eliminate interferences. Calibration curves showed good fitness (R2 > 0.995) for all mycotoxins tested. The method detection limit (MDL) and method quantification limit (MQL) for eight mycotoxins were in the range of 0.002 - 0.2 and 0.005 - 0.5 ng/g, respectively. The recoveries ranged from 98.2 to 111% at three concentrations. The coefficients of variation (CVs) ranged from 1.2 to 14% intraday, and 1.4 to 13% interday. These results were within the acceptable range of the Codex Alimentarius Commission (CAC), thus indicating that the validated method could be suitable for multimycotoxin detection in roasted coffee samples.

Published: May 2023

Fortification with micronutrient powders (MNPs) is recommended as a strategy for increasing the micronutrient content in complementary foods. However, plant-based diets commonly consumed in developing countries are rich in phytates and tannins, which decrease the micronutrient bioavailability. The present work analysed the relationship between the antinutrient content, and also iron and zinc bioaccessibility, in home-made MNP-fortified complementary feeding porridges refined with white rice, maize, white sorghum, finger millet, pearl millet, Irish potato, and banana samples, which were obtained from the local market and milled into flour. Porridges were prepared using the flour, cooled to 50°C, fortified with MNPs, and subjected to in vitro digestion. Total and bioaccessible zinc and iron were quantified using atomic absorption spectrometry. Tannins and phytates were analysed using Folin-Denis and high-performance liquid chromatography methods, respectively. Porridges were classified as having poor bioavailability if their phytate-zinc and phytate-iron molar ratios were > 15 and > 0.4, respectively. Only pearl millet and soybeans showed tannin levels higher than the recommended values. The lowest phytate level was observed in refined white rice (0.11 ± 0.04 g/100 g), and the highest was in pearl millet (2.83 ± 0.10 g/100 g). Zinc bioaccessibility ranged from 7.31% (finger millet) to 26.05% (corn-soy blend). Only pearl millet porridge was classified as having poor zinc bioavailability. Iron bioaccessibility ranged from 20.73% (refined white rice) to 0.62% (pearl millet). Refined white rice and Irish potato were the only foods with the phytate-iron ratio within the recommended range. Iron bioaccessibility decreased significantly with an increase in both tannin (r = -0.31, p = 0.045) and phytate (r = -0.39, p = 0.01) contents. Zinc bioaccessibility showed a significant positive relationship with tannin levels (r = 0.41, p = 0.008), but an insignificant inverse relationship with phytate levels (r = -0.072, p = 0.700). Iron bioaccessibility was adversely affected by phytate and tannin levels. To improve iron and zinc bioavailability in complementary foods, strategies for lowering the phytate and tannin contents at the household level are recommended.

Published: May 2023

The Kyoto Protocol has become a promising component for solving one of the most urgent and discussed problems by scientists – air pollution. Therefore, it remains important to consider what has actually been achieved over the 17 years of the treaty; what effects (environmental or economic) prevail as a result of its action. In this research, special emphasis is placed on the impact of the Kyoto Protocol on certain regions, such as Europe, Asia, America and others. Thus, the purpose of the work is to demonstrate how this agreement influenced the development of countries in certain regions, what consequences it led to and how effective it turned out to be. The following research methods were used in the work: statistical, graphic, historical, modelling and forecasting. While writing the work, it was demonstrated what advantages and disadvantages the Kyoto Protocol has as a document for protecting the external environment. In addition, the authors described the main environmental benefits and economic losses from this agreement. The research has demonstrated that the Kyoto Protocol does reduce CO2 emissions in some regions and likely reduces the rate of growth in others. However, a general decline in industrial development was observed in the countries participating in the agreement. The authors conclude that it is currently impossible to say with certainty how effective this agreement will be, but its adverse political and economic consequences will be far less than the environmental benefits. In addition, regional features of the impact of the Kyoto Protocol on the development of local countries were considered. The work allows for a new perspective on the effectiveness of the Kyoto Protocol and provides new answers to questions about the usefulness of this document and the rationality of implementing its terms
The effect of the application of liquid complex fertilizers and mixtures based on them on the productivity of corn in the conditions of the Western Polissia

Published: May 2023

The issues of optimising the phosphorous nutrition of corn are becoming increasingly relevant due to trends in the increasing cost of mineral fertilisers and meteorological risks in the post-sowing period. The purpose of the study is to determine the economic efficiency of liquid complex fertilisers applied during corn sowing as the main source of phosphorus and as an additional element in the nutrition system. A field experiment was performed, which included options for applying LCF, separate application of granular mineral fertiliser, joint use of LCF and granular fertiliser, and tank mixtures of LCF with zinc and a bacterial product based on Pseudomonas fluorenses to implement the set tasks. It was identified that the use of LCF in sowing contributes to a better supply of young plants with phosphorus, and, as a result, to the development of a more productive cob. Therewith, the use of LCF exclusively as a food source in doses up to 50-60 L/ha does not allow for realising the inherent potential and leads to a lack of grains from the cob compared with the option with full nutrition. The highest yield was obtained in the version using granular fertiliser and 60 litres of liquid complex fertiliser mixed with a bacterial preparation, while the yield increase relative to the version without granular fertiliser was 32% (2.8 t/ha). Separate application of liquid complex fertiliser under no circumstances provided a result comparable to the application of granular fertiliser, but the addition of 25 L/ha of LCF to the main application of granular fertiliser allowed obtaining a yield increase of 1.3 t/ha. The results obtained prove the high efficiency of the liquid form of starter fertiliser when applied on light granulometric soils and should be considered when planning resource-saving technology for growing corn in an area with a high degree of meteorological risks

"Короткая сеть на рудотермических производствах, осуществляющая передачу электрической энергии от печного трансформатора к электродам печи является одним из важнейших элементов. Одним из ее наиболее часто встречающихся электрических повреждений в ней являются дуговые замыкания, которые способны за очень короткое время осуществить полное разрушение весьма дорогостоящего шинного пакета. Определение токов в элементах шинного пакета при дуговых замыканиях сопряжено со значительными трудностями из-за сложной конфигурации короткой сети и больших токов в ней. В связи с этим предложена экспериментальная установка для определения сопротивлений элементов шинного пакета короткой сети, в которой обратный измерительный проводник размещают в геометрическом центре шинного пакета, а в качестве прямого провода используют ближайшую к нему трубошину. Это позволяет в значительной степени избавиться от ЭДС, индуктируемой в контурах измерительной схемы магнитными полями от токов в фазах короткой сети. Для упрощения определения токов и сопротивлений в элементах шинного пакета по полученным экспериментальным данным разработана программа «LINE1» в среде Turbo Basic. Предложена методика определения токов в элементах шинного пакета в случае возникновения дугового замыкания между трубошинами одной из пар, которая базируется на использовании ее расчетных данных.

"Для обеспечения активного развития линий городского электрического транспорта необходимо сокращение затрат на их строительство, что в ряде случаев может быть достигнуто путем отказа от сооружения новых тяговых подстанций на продлеваемых линиях при наличии резерва мощности системы тягового электроснабжения на действующих участках. В этом случае возникает проблема передачи энергии по секциям тяговой сети повышенной протяженности, имеющим одностороннее питание. Чтобы обеспечить передачу электрической энергии по контактной сети на большое расстояние, возможно применение усиливающих проводов, а также установка накопителей энергии. В работе рассматривается установка аккумуляторных накопителей, получающих энергию из контактной сети в периоды низкой нагрузки и отдающих её в периоды наибольшего потребления при пуске вагонов. По сравнению с применением вагонов с автономным ходом, предложенный подход требует меньших затрат и обеспечивается возможность эксплуатации всего имеющегося парка подвижного состава на вновь строящемся участке. Методом вероятностного эксперимента определено допустимое количество подвижного состава на продлеваемых секциях и требуемая мощность накопителя энергии. Выполнен анализ режимов работы накопителя энергии, определено оптимальное напряжение перехода между режимами заряда и разряда.

GIS AND REMOTE SENSING IN ESTIMATION OF THE AGRICULTURE LANDS INFRINGEMENT, CASE STUDY: KOM HAMADA, BEHIERA
Authors: Hamdy Ebtsam , Eshra Nadia , Eshra Abeer , El-Feshawy Nawal
Published: May 2023

The paper aims to assess agricultural land infringement using satellite images by applying three methods of classification: supervised (maximum likelihood), unsupervised and normalized difference vegetation index. To determine which sets of remote sensing satellite images were the best, they were compared. During the monitoring periods (2010–2011 and 2020–2021), Beban village is used as a study area. Landsat 8, Sentinel 2, Aster, and Modes satellite images are used to generate the remote sensing data. This period has been selected to classify images in order to assess land cover changes and the infringement of agricultural lands within Beban village and Kom Hamada center. The proposed methods employ the multi-spectral remote sensing data technique for land cover classification, with the selection of a satellite image dependent on the comparisons between the data quality of each satellite image downloaded for the study area. For land cover classification, some band combinations of the remotely sensed data are exploited, and the spatial distributions such as urban areas, agricultural land, and water resources are interpreted. The results give two important points: the Landsat 8 OLI/TIRS sensor is the best when compared with the other satellite, and the second point for the percentage of agricultural land in the study area in 2020, 2015, and 2010 was estimated to be 77.76%, 78.88%, and 84.04%, respectively. That is, agricultural land infringement accounted for 6.28% of Beban Village's total area.

Published: May 2023

The Toukomtore dam in Burkina Faso was built as a road embankment to meet the water needs of the populations of the commune of Koubri. The dam's watershed is not immune to the various climatic and anthropogenic pressures that have caused it to fill up. The objective of this study is to identify the sources of sediment supply to the dam. To do this, the study relies on documentary research, individual interviews with agents of the deconcentrated technical services of the State and users as well as field observations. The results of the study reveal that the sediments in the dam basin come from intense gullying areas, bare areas, bank erosion, market gardening plots and local drains, but also from aggregate extraction sites and brick factories. The results also show that the basin of the dam has lost its initial capacity of reception due to the phenomenon of filling. These results provide indicative elements on the potential origin of the sediments of the dam and are useful for the implementation of the recommendations that have been formulated.
Comparison of the effects of dry needling technique and combination of different manual therapy techniques on electrophysiological and psychological status in patients with myofascial pain syndrome - randomized, controlled, single blind, a pilot study

Published: May 2023

Aims: Our aim was to compare the electrophysiological and psychometric properties of the effects of the dry needling
technique, graston technique, and muscle energy technique in treating myofascial pain syndrome.
Methods: The study included 21 patients diagnosed with myofascial pain syndrome (MPS) and an active trigger point in the
upper trapezius muscle. The patients were randomly divided into three groups of 7 each. The first group received only exercise and dry needling technique (DNT), the second group received graston technique (GT), muscle energy technique (MET) and exercise, and the third group received only exercise. Evaluations were conducted before and after treatment. The trigger point detected with an algometer in the upper trapezius muscle was evaluated with needle electromyography (EMG). The study used the Beck Depression Inventory (BDI) to determine its effects on psychological state.
Results: The change in EMG variable over time was significant in each treatment group (p<0.05). The improvement in EMG
change was more pronounced in the DNT group compared to the other groups. There was also a significant decrease in BDI
scores before and after treatment (p<0.05). Pairwise comparison analysis revealed an improvement in the BDI scores of all
groups, except the control (exercise) group, after treatment, when compared to pre-treatment.
Conclusion: During the trigger point needle EMG examination of all subjects in the study, we detected spontaneous muscle
activity (SMA) in addition to entry activity. After treatment, we observed improvement in SMA. These results suggest that the applied techniques are effective in treating trigger points.The effectiveness of the applied techniques can be evaluated in terms of creating alternatives.

Published: May 2023

This investigation included two integrated experiments, the first one is the microbiological experiment that carried out in Microbial Biotechnology Department, NRC, Cairo, Egypt, where multiple incorporation strategies were used for production zinc oxide Nanoparticles by enrichment of yeast with zinc including; (1): In the first procedure, zinc was added to the liquid medium just after the yeast was inoculated (growth phase), (2): For integration, it was added after 24 h of incubation (non-growth phase) in the second procedure. The obtained results showed that the first method (growth phase) was adopted in order to reduce the chance of medium contamination. Zinc sulphate has no passive effect on yeast cell biomass. The second experiment is horticultural one which was done in National Research Centre greenhouse on Flame seedless grape seedlings which included five treatments as follows: control (spraying with water only), frozen yeast enriched with zinc (as foliar spray), active yeast enriched with zinc (as foliar spray), frozen yeast enriched with zinc (as soil application) and active yeast enriched with zinc (as soil application). When zinc content in the grape leaves as ppm was examine after 15 days, the results showed that active fresh yeast enriched with zinc that treated as foliar spray recorded the highest rate of zinc in grape leaves (180 ppm), followed by active fresh yeast enriched with zinc as soil application which recorded 170.8 ppm. On the other hand, the untreated plants (control) showed the lowest value of zinc in the leaves (91.6 ppm) when compared with the other treatments.

This research study aims to determine the effectiveness of using the Bamboo (Bambuseae) Fibers as medium for enhancing the durability and strength of the concrete and compare it to the common ones without fibers. This study utilized the experimental approach in quantitative research to ensure the fairness of the result. The study was conducted in Sto. Tomas National High School last September 2018. To test the effectiveness of the fiber to the concrete, the researchers conducted a 6-feet drop test along with the ones without fibers. The data gathered were analyzed using Chi- square test to determine the significant effect of the bamboo fiber in enhancing the concrete cement. It was found out that the concrete with fiber is more durable than the ones without fibers after the Drop test. This study encourages the use of bamboo fibers to enhance the strength and durability of the concrete.
Tweeting Public Service Complaints
Authors: O'Brochta William
Published: May 2023

Many local governments have added new methods to report public service complaints like submitting a complaint on Twitter, hoping to expand access to more constituents. But who submits Twitter complaints, and how do those complaints compare to those submitted using other methods? I collect data on complaints submitted to the City of St. Louis and use these data to show that complaints submitted on Twitter are primarily from wealthy white residents concerned about issues related to parks or to their commutes. These types of complaints differ sharply from those submitted using other methods. Hence this descriptive evidence lends credence to the idea that providing a Twitter account to submit complaints may not expand access to local government services as much as previously thought. Local governments may want to carefully consider how the methods that they provide to submit public service complaints could help to determine the types of complaints they are likely to receive.

Published: May 2023

This article examines the cases of proportionality of the principles of the CPC, which are the procedural grounds for exemption from criminal liability, the institution of refusal and termination of proceedings, and the guidelines of Criminal Procedural legislation. At the same time, opinions and views on the importance of the principles of the Criminal Procedural Code, its role in legislation and its role in the development of this area of legislation have been studied. The article highlights inconsistencies in the practice of refusal to initiate criminal proceedings and termination of criminal proceedings, as well as conflicting circumstances. Considerations regarding the principle of the inevitability of initiating a criminal case, which is considered one of the principles of the CPC, the reasons for its existence, the establishment in legislation, the tendency to change and its role are also studied. The methods of analysis, synthesis, induction, deduction, comparative legal analysis have been used in the research. In the course of the study, advanced foreign experience, scientific and theoretical views and investigative and judicial practice have been studied, as a result of which proposals and recommendations have been developed for making appropriate amendments or additions to the Criminal Procedural Code of the Republic of Uzbekistan.
Towards an improved understanding of wildfire CO emissions: a satellite remote-sensing perspective
Authors: Griffin Debora , Chen Jack , Anderson Kerry , Makar Paul , McLinden Chris A. , Dammers Enrico , Fogal Andre
Published: May 2023

Abstract. Emissions from wildfires are a significant source of air pollution, which can adversely impact air quality and ecosystems thousands of kilometers downwind. These emissions can be estimated by a bottom-up approach, using inputs such fuel type, burned area, and standardized emission factors. Emissions are also commonly derived with a top-down approach, using satellite observed fire radiative power (FRP) as proxy for fuel consumption. More recently, wildfire emissions have been demonstrated to be estimated directly from satellite observations, including carbon monoxide (CO). Here, we explore the potential of satellite-derived CO emission rates from wildfires and provide new insights into the understanding of satellite-derived fire CO emissions globally, with respect to differences in regions and vegetation type. Specifically, we use the TROPOMI (Tropospheric Monitoring Instrument) high spatial-resolution satellite datasets to create a global inventory database of burning emissions CO emissions between 2019 and 2021. Our retrieval methodology includes an analysis of conditions under which emission estimates may be inaccurate and filters these accordingly. Additionally, we determine biome specific emission coefficients (emissions relative to FRP) and show how combining the satellite derived CO emissions with satellite observed FRP from the Moderate Resolution Imaging Spectrometer (MODIS) establishes an annual CO emission budget from wildfires. The resulting emissions totals are compared to other top-down and bottom-up emission inventories over the past two decades. In general, the satellite-derived emissions inventory values and bottom-up emissions inventories have similar CO emissions totals across different global regions, though the discrepancies may be large for some regions (Southern Hemisphere South America, Southern Hemisphere Africa, Southeast Asia) and for some bottom-up inventories (e.g. FINN2.5, where CO emissions are a factor of 2 to 5 higher than other inventories). Overall, these estimates can help to validate emission inventories and predictive air quality models, and help to identify limitations present in existing bottom-up emissions inventory estimates.
Modelling the barotropic sea level in the Mediterranean Sea using data assimilation
Authors: Bajo Marco , Ferrarin Christian , Umgiesser Georg , Bonometto Andrea , Coraci Elisa
Published: May 2023

Abstract. This paper analyses the variability of the sea level barotropic components in the Mediterranean Sea and their
reproduction using a hydrodynamic model with and without data assimilation.
The impact of data assimilation is considered both in reanalysis and short-forecast simulations.
We used a two-dimensional finite element model paired with an ensemble Kalman
filter, which assimilated hourly sea level data from 50 stations in the Mediterranean basin. The
results brought about a significant improvement given by data assimilation in the reanalysis of
the astronomical tide, the surge, and the barotropic total sea level, even in coastal areas
and far from the assimilated stations (e.g. the southeastern Mediterranean Sea).
As with the reanalysis simulations, the forecast simulations, which start from analysis states,
improve, especially on the first day (37 % average error reduction) and when
seiche oscillations are triggered.
Since seiches are free barotropic oscillations that depend only on the initial state, their
reproduction improves very effectively with data assimilation. Finally, we estimate the
periods and the energy of these oscillations by means of spectral analysis, both in the Adriatic Sea,
where they have been extensively studied, and in the Mediterranean Sea, where the present
documentation is scarce. While the periods are well reproduced by the model even without
data assimilation, their energy shows a good improvement when using it.
