Lupin (Lupinus albus L.) Seeds: Balancing the Good and the Bad and Addressing Future Challenges
Authors: Pereira Ana , Ramos Fernando , Sanches Silva Ana
Published: December 2022

Lupinus albus L. (lupine) is a legume whose grain/seed has gained increasing interest. Its recognized nutritional properties, namely a high content of protein, dietary fiber and its low fat content, make lupine a suitable alternative not only for animal protein, but also as a substitute for more processed and less balanced flours from a nutritional point of view, used in the preparation of bread, cakes and cookies, among others. In addition, its nutritional and bioactive compounds have potential benefits for human health in the prevention and treatment of some diseases. However, the existence of some anti-nutritional compounds and contaminants reveal some concern, requiring effective methods for their detection and eventual removal. This review intends to address the potential of lupine (L. albus) in food and human health and to balance the pros and cons. Nutritional and anti-nutritional components of L. albus seeds and possible contaminants of lupine seeds are examined. The potential health benefits of lupine (seeds), including energy metabolism, cardiovascular diseases, hypertension, glucose and insulin metabolism, bower function and anticonvulsant action, are discussed based on scientific evidence (both clinical trials and studies performed with animal models).

Published: December 2022

The specific features of the siloxane bond unify the compounds based on it into a class with its own chemistry and unique combinations of chemical and physical properties. An illustration of their chemical peculiarity is the behavior of 1,3-bis(2-aminoethylaminomethyl)tetramethyldisiloxane (AEAMDS) in the reaction with carbonyl compounds and metal salts, by which we obtain the metal complexes of the corresponding Schiff bases formed in situ. Depending on the reaction conditions, the fragmentation of this compound takes place at the siloxane bond, but, in most cases, it is in the organic moieties in the β position with respect to the silicon atom. The main compounds that were formed based on the moieties resulting from the splitting of this diamine were isolated and characterized from a structural point of view. Depending on the presence or not of the metal salt in the reaction mixture, these are metal complexes with organic ligands (either dangling or not dangling silanol tails), or organic compounds. Through theoretical calculations, electrons that appear in the structure of the siloxane bond in different contexts and that lead to such fragmentations have been assessed.

Three new Pt(II) complexes [(dpp-DAD)PtCl2] (I), [(Mes-DAD(Me)2)PtCl2] (II) and [(dpp-DAD(Me)2)PtCl2] (III) were synthesized by the direct reaction of [(CH3CN)2PtCl2] and corresponding redox-active 1,4-diaza-1,3-butadienes (DAD). The compounds were isolated in a single crystal form and their molecular structures were determined by X-ray diffraction. The purity of the complexes and their stability in solution was confirmed by NMR analysis. The Pt(II) ions in all compounds are in a square planar environment. The electrochemical reduction of complexes I–III proceeds in two successive cathodic stages. The first quasi-reversible reduction leads to the relatively stable monoanionic complexes; the second cathodic stage is irreversible. The coordination of 1,4-diaza-1,3-butadienes ligands with PtCl2 increases the reduction potential and the electron acceptor ability of the DAD ligands. The synthesized compounds were tested in relation to an adenocarcinoma of the ovary (SKOV3).

Published: December 2022

Eucommia ulmoides Oliver staminate flower (ESF) tea enjoys a good reputation in folk medicine and displays multiple bioactivities, such as antioxidant and antifatigue properties. However, the underlying biological mechanisms remain largely unknown. In this study, we aimed to investigate whether ESF tea can mitigate cellular oxidative stress. Crude ethyl alcohol extract and its three subfractions prepared by sequential extraction with chloroform, n-butyl alcohol and residual water were prepared from ESF tea. The results of antioxidant activity tests in vitro manifested n-butyl alcohol fraction (n-BUF) showed the strongest antioxidant capacity (DPPH: IC50 = 24.45 ± 0.74 μg/mL, ABTS: IC50 = 17.25 ± 0.04 μg/mL). Moreover, all subfractions of ESF tea, especially the n-BUF, exhibited an obvious capacity to scavenge the reactive oxygen species (ROS) and stimulate the NRF2 antioxidative response in human keratinocytes HaCaT treated by H2O2. Using ultra-high-performance liquid chromatography, we identified geniposidic acid (GPA) as the most abundant component in ESF tea extract. Furthermore, it was found that GPA relieved oxidative stress in H2O2-induced HaCaT cells by activating the Akt/Nrf2/OGG1 pathway. Our findings indicated that ESF tea may be a source of natural antioxidants to protect against skin cell oxidative damage and deserves further development and utilization.

The purpose of this research study was to develop an analytical method for the quantification of 7-nitroso-3-(trifluoromethyl)-5,6,7,8-tetrahydro-[1,2,4] triazolo [4,3-a] pyrazine (7-nitroso impurity), which is a potential genotoxic impurity. Since sitagliptin is an anti-diabetic medication used to treat type 2 diabetes and the duration of the treatment is long-term, the content of nitroso impurity must be controlled by using suitable techniques. To quantify this impurity, a highly sensitive and reproducible ultraperformance liquid chromatography with triple quadrupole mass spectrometry (UHPLC-MS/MS) method was developed. The analysis was performed on a Kromasil-100, with a C18 column (100 mm × 4.6 mm with a particle size of 3.5 µm) at an oven temperature of approximately 40 °C. The mobile phase was composed of 0.12% formic acid in water, with methanol as mobile phases A and B, and the flow rate was set to 0.6 mL/min. The method was validated according to the current International Council for Harmonisation (ICH) guidelines with respect to acceptable limits, specificity, reproducibility, accuracy, linearity, precision, ruggedness and robustness. This method is useful for the detection of the impurity at the lowest limit of detection (LOD), which was 0.002 ppm, and the lowest limit of quantification (LOQ), which was 0.005 ppm. This method was linear in the range of 0.005 to 0.06 ppm and the square of the correlation coefficient (R2) was determined to be > 0.99. This method could help to determine the impurity in the regular analysis of sitagliptin drug substances and drug products.
Assessment of Tropical Cyclone Risk to Coral Reefs: Case Study for Australia
Authors: Do Cameron , Saunders Georgia Elizabeth , Kuleshov Yuriy
Published: December 2022

In this study, we attempt to expand tropical cyclone (TC) risk assessment methodology and build an understanding of TC risk to Australia’s natural environment by focusing on coral reefs. TCs are natural hazards known to have the potential to bring destruction due to associated gale-force winds, torrential rain, and storm surge. The focus of TC risk assessment studies has commonly centred around impacts on human livelihoods and infrastructure exposed to TC events. In our earlier study, we created a framework for assessing multi-hazard TC risk to the Australian population and infrastructure at the Local Government Area level. This methodology is used in this study with coral reefs as the focus. TC hazard, exposure, and vulnerability indices were created from selected coral-related datasets to calculate an overall TC risk index for the Ningaloo Reef (NR) and the Great Barrier Reef (GBR) regions. The obtained results demonstrate that the northern NR and the southern GBR had the highest risk values within the study area; however, limitations in data quality have meant that results are estimates at best. The study has shown the potential benefits of such a TC risk assessment framework that can be improved upon, as coral data collection becomes more readily available.
The Design and Maintenance of Low-Orbit Navigation Constellation for Traffic Control in a Smart City
Authors: Zheng Yi , Lin Baojun , Li Rui , Liu Yutong
Published: December 2022

The traffic control issue in the smart city scenario gives rise to the higher requirements of Global Navigation Satellite System (GNSS) services, especially in terms of navigation accuracy, together with coverage continuity, and multiplicity. The dense urban environment leads to higher elevation angles for navigation in such areas, which requires a lower altitude of the constellation, as well as a larger number of satellites. In the existing literature, the design and maintenance of the Low Earth Orbit (LEO) navigation constellation that fulfills the requirements of the smart city are not provided. Hence, based on the requirements and constraints of the smart city scenario, this article studies the relation between orbital height, user elevation angle, and coverage. It designs the configuration of an LEO navigation constellation that not only achieves global sensing coverage, but also provides a continuous lane-level navigation service with multiple coverages for the key area. In addition, considering the atmospheric drag in low orbits and the constraint of satellite power and attitude control, a method is proposed by rotating solar panels to change the effective frontal area of the satellite to achieve relative configuration maintenance of the LEO constellation. The results show that the LEO navigation constellation has a 0 s revisit time in five chosen smart cities, and each city has more than four-times coverage every second; the Geographic Dilution of Precision (GDOP) values of five cities are smaller than 0.47. The average navigation accuracy of five cities is 2.01. With the conduction of the one-year station-keeping simulation, the phase deviation of two satellites is less than 0.6° and it gradually converges to 0.1°, where the semi-major axis deviation is less than 80 m. With our proposed method, the active station-keeping control is not needed in one year, and the fuel consumption can be reduced. Finally, the continuity of the navigation service can be assured.
Bekenstein Bound and Non-Commutative Canonical Variables
Authors: Scardigli Fabio
Published: December 2022

A universal upper limit on the entropy contained in a localized quantum system of a given size and total energy is expressed by the so-called Bekenstein bound. In a previous paper [Buoninfante, L. et al. 2022], on the basis of general thermodynamic arguments, and in regimes where the equipartition theorem still holds, the Bekenstein bound has been proved practically equivalent to the Heisenberg uncertainty relation. The smooth transition between the Bekenstein bound and the holographic bound suggests a new pair of canonical non-commutative variables, which could be thought to hold in strong gravity regimes.
Despite the large flow of scientific publications devoted to the procedure for mandatory medical examinations by minors during employment, the problems of regulatory regulation of this procedure in the Russian Federation are currently insufficiently investigated. Analyzing the norms of Russian legislation regulating the procedure for medical examinations of minors in the Russian Federation, the authors came to the conclusion that one of the most possible solutions to the problem of employment of adolescents associated with the passage of medical examinations by minors, or rather with the financing of this procedure, would be an increase in additional (economic) guarantees suppressing the employer's reluctance to conclude an employment contract with minors. That is why, at the legislative (federal) level, it is necessary to establish mandatory quotas of places for the employment of minors for certain types of work, which in itself is an additional guarantee of hiring this category of workers as particularly in need of social protection

Authors: Hadi Febri , Sumijan
Published: December 2022

Imagery on edge detection is a process that will display the edges of an image. Basically, edge detection is one of the techniques for the analysis of image quality in the spatial domain and is also one of the initial process in digital image processing. Edge detection serves to detect the border line of an object contained in the image. This study aims to identify and recognize face pattern objects in the capture zoom image. To perform face identification begins with collecting image data, image processing, image edge detection, thinning of the image, and identification process using the template matching method. The method used in edge detection uses 3 methods, namely Sobel, Roberts and Prewitt which are gradient operators to detect edges in facial images. The dataset used is image capture zoom. The trial was carried out in two stages, namely the identification of the face shape and the identification of the edges of the face. The conclusion of the study is that the Roberts operator is the operator that finds the least edge patterns in facial images than the other two operators, namely Prewitt and Sobel. Meanwhile, the Sobel operator produces edge patterns that are better in quality and quantity than using the Roberts and Prewitt operators.

Authors: İLKER Nur Gülümser
Published: December 2022

Laura Restrepo ofrece una perspectiva social de la década entre los años 1980 y los 2000 en Colombia en su novela Delirio. En ella el desorden creado por el terror y la lucha contra el narcotráfico y la brecha entre las clases sociales se colocan en el fondo, mientras que el estado mental del individuo se revela en este ambiente violento. La protagonista de la novela, Agustina, pierde el juicio en los desequilibrios de su familia, que es el indicador de la sociedad colombiana. Algunos datos importantes sobre el manejo de la razón y la percepción de la realidad surgen cuando se examinan las causas subyacentes de la locura de Agustina. La sociedad colombiana rodeada de terror y rabia y la familia donde hay inquietudes son determinantes en la desquicia de Agustina. Pero lo más importante en su pérdida de la razón es la negación de la realidad. Un disfraz de todo lo que sale mal, un orden construido con mentiras y una percepción falsa de la realidad son los elementos que asestan un golpe mortal a Agustina. En este punto, se discutirán en el estudio los efectos de crear realidades falsas y producir mentiras como si todo estuviera bien en la salud mental del individuo. También se discutirá la funcionalidad y destrucción de la mentira en la realidad social e individual. Además se intentará revelar la relación entre la pérdida de la percepción de la realidad y estar al borde de la razón. Por lo tanto, se determinará de qué manera los factores como la aceptación, el rechazo, la confrontación y la lucha afectan la salud mental del individuo.

Published: December 2022

This study aims to analyze the utilization of zakat in an effort to reduce poverty from the perspective of the Koran. Where is Zakat as the third pillar of Islam, that paying zakat is an obligation for every Muslim to purify his wealth by distributing it to the needy and poor according to the criteria set by the Shari'a. The type of research used is qualitative research using thematic methods with a normative approach. The thematic method in question is to collect verses from the Qur'an from all suras related to the theme of poverty, both explicit and implicit. Then the normative review is intended to examine the perspective on zakat and its prevention of poverty based on the Qur'an. Collecting data through literature study on related verses of the Koran and analyzed qualitatively. This study found that Zakat is something that is obligatory for Muslims who can play an active role in poverty reduction through efforts to distribute Zakat to the poor. Furthermore, zakat management must be regulated professionally so that zakat does not only meet consumption needs but can also be managed as a source of income through the use of zakat as business capital and study costs for the poor. Recipients of zakat are not only objects of giving zakat but they must have a responsibility in using zakat as an effort to empower and develop themselves so that they can be independent and can make economic improvements to their families.

Connecting the Functions of Lexical Bundles and Moves in Published Research Articles: The Case of Developmental and Educational Psychology
Authors: Yang Mei
Published: December 2022

The Introduction-Methods-Results-Discussion (IMRD) pattern is frequently used in research articles (RAs) in many disciplines. Following the IMRD format enables writers to organize research content more easily, and thoroughly understanding IMRD sections and their functions will facilitate the writing of IMRD-structured RAs (Mack 2018). Studying lexical bundles, especially their functions, can help understand how research writing is organized. Combining top-down move analysis of RAs with bottom-up frequency-based identification of bundle functions can provide evidence for the occurrence of bundle functions in a particular position of an RA. However, previous studies integrating these two approaches tend to focus on RA Introductions, lacking a systematic investigation of the other three sections. To fill this gap, the present study connects bundle functions and moves in all the sections of RAs in the field of developmental and educational psychology. The results reveal that there are differences between RA sections in terms of the functional distribution of lexical bundles, which are related to the respective roles of the four sections in RAs. The results also show that lexical bundles of certain functions stand out in the moves of each RA section. For novice writers, awareness of such salient combinations of bundle functions and specific moves in the IMRD sections may improve the clarity of argumentation and make their writing more persuasive.

Authors: Winoto Chandra  , Resti Yulia , Bambang Suprihatin
Published: December 2022

Despite the pandemic, Jakarta is one of the most polluted cities in the world. Knowing the daily air quality forecast aids the community, particularly Jakarta residents. Among these is the ability to protect oneself from dangerous air. The multinomial naive Bayes and the decision tree-ID3 methods are popular and perform well. Both of these strategies, however, require categorical variables. This need necessitates the implementation of a discretization technique for numerical variables. The purpose of this study is to predict Jakarta's air quality using the multinomial naive Bayes and decision tree method based on Particulate Matter 10 µg (PM10), Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), Ozone (O3), and Carbon Monoxide (CO). These continuous variables are discretized in two ways: using all midway breakpoints or halfway mixture breakpoints. The results indicated that the decision tree method with the mixture breakpoints halfway approach performed better than the multinomial nave Bayes method, with an accuracy of 98.90%, a specificity of 98.92%, a sensitivity of 75.00%, a precision of 75.00%, and an F1 score of 97.81%.

One of the efforts used so that students' motivation to learn mathematics can rise is by giving ice-breaking in learning mathematics. The purpose of this study was to determine the effect of ice-breaking on the mathematics learning motivation of elementary school students. This study uses a quantitative type with a pre-experimental research design. The research design used was One group Pretest-Posttest Design with a sample of 17 students of SD class V. Data collection techniques were carried out by giving learning motivation questionnaires before treatment (ice-breaking) and after treatment (ice-breaking). breaking). Data analysis consisted of descriptive statistical analysis and inferential statistics in the form of hypothesis testing using t-test. From the results of hypothesis testing using t-test, it is known that there is a difference in average motivation to learn before and after ice-breaking. The average motivation to learn after ice-breaking is higher than before ice-breaking. Thus it can be concluded that there is an effect of giving ice-breaking on learning motivation.

This article describes the exploration results of the verses of the Qur'an, which contain the concept of monotheism with a numerical value of one. This research started from learning number recognition in class, which still seemed monotonous. Furthermore, the limitations of teaching materials make integrating mathematics learning with Islamic science more difficult. Numbers have an important role in various aspects of life. Al-Qur'an, the main subject taught in Islamic schools, can be used as initial knowledge to support learning mathematics. Therefore, introducing numbers to students must be integrated with Islamic science, especially monotheism in learning at school, to lead students to successful learning and a change in religious awareness. The data collection techniques used are documents such as interpretations of the Qur'an, the Qur'an and their translations, articles, journals, books, or other literature related to mathematics and the Qur'an. The information in this study was derived from search and collection results obtained through the Ministry of Religion's Qur'an application, the Indonesian Qur'an application, and other data in the form of documents. Then, the data analysis technique used to get the numerical value of one in the Qur'an is the Miles & Huberman analysis method combined with Rodriguez modeling and "fadic" system calculations. Based on a combination of analytical theory, 16 verses of the Qur'an contain the concept of monotheism with a numerical value of one from comprehensive exploration, which is 135 verses.

Introduction: The modern educational environment involves the use of various electronic devices generating physical hazards. In addition to the widespread use of these devices, other physical factors of the school environment also affect schoolchildren’s health. However, the impact of the combined exposure to physical factors of various nature on the regulatory systems of the body has been studied insufficiently so far. However, the influence of a complex of physical factors of various nature on the regulatory systems of the body has not been sufficiently studied.
Objective: To evaluate the features of the immune and neuroendocrine status of schoolchildren exposed to heterogeneous physical factors of a non-ionizing nature at school and to analyze the relationship between the studied physical factors and
changes in the parameters of regulatory systems.
Materials and methods: The exposed group included 144 students of a gymnasium from the city of Perm and the unexposed (reference) group consisted of 114 schoolchildren from the town of Kungur, Perm Region. We measured physical factors of the school environment, including noise, artificial illumination, electromagnetic radiation, and air ion concentrations affecting elementary, secondary, and high school students from both groups and compared the results with respective permissible levels. The indicators of immune (CD-phenotyping, phagocytic activity of leukocytes, concentrations of immunoglobulins and cytokines) and neuroendocrine (TSH, free T4, and cortisol) systems were established and compared. Mathematical models were calculated and analyzed in order to find the links between the exposure to physical factors under study and the
parameters of the immune and neuroendocrine systems.
Results: The indoor air study showed differences in the number and charge of air ions between the gymnasium with its numerous e-learning tools and the school of comparison. The study of the immune and neuroendocrine systems in the exposed
group revealed age-related changes in the expression of lymphocyte subpopulations, moderate changes in humoral and phagocytic parameters, an imbalance in the expression of pro- and anti-inflammatory cytokines and hormones. The construction of logistic regression models allowed us to establish the link between the parameters of electromagnetic radiation in the school environment and changes in the immune status of students (CD19+ and CD3+CD8+ lymphocytes).
Conclusion: The study demonstrated a number of changes in the regulatory systems of schoolchildren associated with the impact of physical factors of the school environment.

Introduction: An urgent hygienic problem in the regions with intensive industrial development is the persistence of ambient air pollutants and their adverse health outcomes in the population leading to higher incidence rates of non-communicable diseases and their chronicity.
Objective: To substantiate the relationships between high blood levels of copper, nickel, and chromium and biomarkers of their adverse effects on blood, respiratory and immune systems for the tasks of early detection and prevention of poor health outcomes
of the combined inhalation exposure to copper, nickel and chromium oxides on the example of the adult population at risk.
Materials and methods: We carried out a hygienic assessment of ambient air quality in residential areas and analyzed general population incidence and prevalence for 2016–2020. We also examined the health status of women of reproductive age environmentally exposed to nickel, chromium and copper oxides in the area of residence and of relatively unexposed controls. About 5,000 chemical, clinical, immunological, and biochemical tests were done in 2022.
Results: We established associations between higher blood levels of copper, nickel, and chromium and changes in the indicators of adverse health effects. Biomarkers of nonspecific and specific sensitization, chronic inflammation accompanied by an imbalance in the humoral and cellular immunity were hyperproduction of eosinophils in the nasal mucus, blood lymphocytes, specific IgG to copper, a decrease in the phagocytic index and number; lower ferritin marked disorders of iron homeostasis, higher malondialdehyde indicated induction of oxidative processes, and a decrease in antioxidant activity gave evidence of depletion of the total antioxidant activity.
Conclusions: It is expedient to use our findings for early detection and subsequent substantiation of targeted measures aimed at preventing disorders of the respiratory and immune systems, blood, and certain disorders involving the immune mechanism,
etiopathogenetically related to the combined exposure to the metal oxides tested.
