La riqueza pictórica mural de la civilización maya se ha conservado escasamente, debido en gran medida a la intensa humedad y a otros factores climáticos propios de la selva tropical. Sin embargo, todavía es posible observar ejemplos de ese tipo de arte en distintos sitios, entre los que destacan Bonampak, Tikal, Calakmul, Chacmultún, Chichén Itzá, Palenque, San Bartolo y Tulum, entre otros. En esos casos es evidente que los mayas de ayer plasmaron eventos, deidades y personajes relevantes mediante una serie de pigmentos aplicados en paredes interiores y en paños de muros externos. Estos últimos, por lo general, han sido los primeros en desaparecer por efecto de su exposición a los elementos naturales, mientras que las escenas en espacios interiores han perdurado hasta nuestros días por condiciones realmente excepcionales.

En épocas recientes, la región del sur de Quintana Roo ha cobrado relevancia dentro de los estudios arqueológicos y epigráficos del área maya debido, en gran medida, a la presencia de la dinastía Kaanu’l en distintos sitios de la región, principalmente en Dzibanché, que fungió como capital de la entidad política de la Cabeza de Serpiente desde la segunda mitad del Clásico Temprano. De igual manera, información procedente de asentamientos como Pol Box y El Resbalón han complementado y enriquecido nuestra visión sobre la presencia de dicha dinastía y la red de contactos que construyó para extender su dominio más allá de las fronteras del señorío.
Demographic Component of National Security
Authors: Imideeva Irina , Badaraeva Renata , Kovanova Ekaterina
Published: March 2023

The change in the values of modern society has changed the emphasis in the definition of the main factors characterizing national security. The aging of the population, increasing costs of medicine and pension payments, increasing economic burden on the working-age population give reasons to consider the demographic component as the main one in the system of national security. The article deals with the problem of determining those demographic factors that have the greatest impact on national security. The aim of the study is to quantify the influence of individual demographic factors on the national security indices. It compares the main demographic indicators of the Russian Federation and developed countries; uses data for developed countries to determine the boundary values of the main demographic indicators; constructs regression dependencies that determine the dynamics of demographic indicators for the Russian Federation; determines the generalized index of the demographic component of national security of the Russian Federation; calculates elasticity coefficients to determine the impact of individual demographic indicators; develops recommendations to improve the demographic composition of the Russian Federation. It has been established that previously unrecorded parameters of demographic security indicators (the share of the elderly population in the total population and the demographic burden of the elderly) are important in the assessment of national security. For the Russian Federation, all indicators are in the critical zone (below the minimum threshold value).
Discrimination against Migrants in the Moscow Rental Market (Case Study of Iranian and Tajik Students)
Authors: Afzali Mehdi , Vazirov Zafar , Bezverbnaya Natal’ya
Published: March 2023

For finding accommodation in Moscow, international students face many discriminatory advertisements and landlords who refuse to lend their properties to immigrants because of their ethnicities, religion, etc., which puts tremendous pressure on international students. However, the landlords might believe that their behavior is not discriminating. Therefore, in this study, we aim to investigate the existence of discrimination against Iranian and Tajik students in Moscow’s rental market. We have chosen Iranian and Tajik students currently studying in Moscow since the students from these two countries share a similar language, religion, and culture. This study uses a qualitative approach based on a structured interview consisting of 15 questions to understand the problems Iranian and Tajik students face in Moscow’s rental market. Also, we analyzed 1,221 rental advertisements to determine the number of discriminatory expressions on Russian real estate websites and applications. The results show that discriminative words such as “Strictly Slav,” “Only Slav,” and “Slav (Russian citizens only)” include almost 25% of the advertisements on internet websites. The study results also show that landlords refuse to lend an apartment, room, or bed to Iranian and Tajik students for almost the same reasons, such as their ethnicities, religion, and a citizen of another country rather than the Russian federation being a student. We can conclude that the role of universities in facilitating the housing problems of international students and the role of the government in providing juridical access in terms of discrimination is essential.
Science and technology policy of the Russia and reserves of interaction between academic, university and entrepreneurial sectors of science
Authors: Savinkov Vladimir
Published: March 2023

In the last 15 years the Russian Federation has been declared an economic obstruction, associated with the attempt of Western countries to oust Russia from the external commodity and financial markets. The embargoes imposed by the West have largely affected the domestic market because of its excessive saturation with imported goods. Import substitution policy initiated by the Government more than 10 years ago could not solve the problem of shortage of high-tech products due to technological backwardness of many enterprises of civil economy, including due to insufficient involvement of domestic science to assist in the development of innovative production. There are also problems in Russian science itself. The main one is underfunding of research as a consequence of weak development of entrepreneurial and state market of orders for scientific products. Most commercial structures prefer to acquire ready-made patents or technologies from foreign firms. There is no optimal mechanism for administrative coordination and financial subsidizing of creative interaction between the three sectors of science to solve problems relevant from the position of domestic and foreign policy. All-Russian studies conducted with the author's participation in 2011–2020 show the positive experience of cooperative interaction between different sectors of science with mixed public-private financing and in the reliance on the technological platform of manufacturing companies. This is the practice for 80% of scientific organizations performing applied research. As for the basic sciences, in this segment close cooperation of academic research institutes is not only possible but also desirable with universities, both in the framework of megaprojects and in the preparation of textbooks for universities.
Economic and social consequences of the ban on the employment of foreign workers (example of the Central Federal District)
Authors: Ispovednikov Dmitry
Published: March 2023

The article for the first time examines the experience of regulating international migration by imposing bans on attracting foreign citizens who work on the basis of patents in certain types of economic activity. The study was conducted on the basis of a comparison of the socio-economic indicators of the regions of the Central Federal District that use this tool (Tver and Voronezh regions), never used it (Moscow) and recently joined the practice (Kaluga region). The statistic for 2014-2022, reflecting the dynamics of external migration flows, the state of internal labor resources and individual sectors of the economy, as well as the level of crime among migrants, is analyzed. Conclusions about the prohibitive practice as a practice, which has little effect on the studied indices of protectionist regions and weakly distinguishes them from the background of other regions, are drawn. The number of issued patents in the Tver region is declining with a slight decrease in international labor migration in general, which indicates a change in the proportion of the foreign labor force in favor of a category, that does not require a patent. The dynamics of the gross regional product indicators for the groups of economic activities forbidden for the employment of foreign citizens coincides with the general upward trend due to an increase in labor productivity in all the subjects under consideration. Crime among foreign citizens in the Tver region before the pandemic was declining with an increase in the number of crimes committed against foreigners, which corresponded to the dynamics in Moscow and in the district as a whole. It seems promising to confirm or refute the obtained conclusions based on the results of studying the indices of all protectionist regions of the Russian Federation, which will improve the methods of forecasting and managing migration processes. It is also noted the need to expand the range of available data by forming a single digital database that makes it possible to trace the process of attracting foreign citizens at control points: medical (passing a medical examination), educational (passing an exam in the Russian language, Russian history and the basics of Russian legislation), financial (payment indicators monthly imputed patent tax).
Transformation of the consumption paradigm in modern Russian society
Authors: Medvedeva Elena , Kroshilin Sergey , Avacheva Tatiana
Published: March 2023

The purpose of this study was to identify the main trends in the transformation of consumer preferences of Russians, which have recently been largely associated with the pandemic situation inside the country, the unprecedented influence of exogenous and endogenous factors, sanctions pressure, with the departure of more "brands" from the Russian market. All this together has radically affected consumer preferences. The object of the study is the consumer dominants of Russians' choice. The subject is current trends in changing preferences due to external and internal factors, as well as the attitude towards them on the part of Russian consumers of goods and services. The pandemic has made significant changes not only in the socio-economic situation in the country, but also significantly affected consumer choice. Not only the preferences themselves have changed, but also the method /structure of purchasing goods. To a large extent, "purchases" have moved to the Internet. Having failed to adapt to the "tough" conditions of "purchasing goods remotely", the Russian consumer faced significant changes in the domestic market of goods and services caused by sanctions from foreign manufacturers, partial or complete withdrawal of "familiar" brands. Changes in the socio-economic situation, the level of income of citizens, consumer confidence, credit confidence largely determine the behavior of the domestic consumer today. In the article, the authors use analytical approaches and statistical methods of comparison based on the analysis of secondary and obtaining primary data on the studied problem. The uniqueness of the study lies in the fact that the current situation is "non-standard" for the domestic market, when economic and social problems are caused not only by crisis phenomena, but also by unprecedented negative behavior of foreign manufacturers, which have traditionally been represented on the domestic market. The data of the author's studies conducted before and during the Pandemic were used as primary information. They were associated with the study of the characteristics of consumer preferences. The results of the study can be practically significant for scientists, specialists, as well as researchers who study the consumer behavior of Russians.
Homo Ludens in the post-truth game world
Authors: Mamedov Agamali , Komissarov Sergey , Korkiya Eka
Published: March 2023

The article analyses the characteristics of the phenomenon of post-truth as a term denoting a radical transformation of the media, that abandoned freedom of speech and objectivity of information in favour of the geopolitical interests of the West, considers the content of the concept of "post-truth" in modern scientific discourse; it is noted that the entry of civilisation into the era of mastering information as a leading source requires the scientific community to comprehend the problems associated with the finiteness of the connection between the semantic volumes of public information and reality, that is reflected in the phenomenon of post-truth. The authors explore the origins of this phenomenon, that fully manifested itself only in the first decades of the 21st century and is associated with the communication "explosion" and the information revolution, that elevated information to the rank of a new global resource. The fragmentation of the perception of reality in the phenomenon of post-truth acts as a means of protecting the human psyche from information overproduction, where information is used as a tool for implementing the geopolitical interests of the collective West, that owns the lion's share of the world media. The authors are not inclined to identify post-truth solely with false information and suggest considering it as the result of practical assimilation and multidirectional understanding by society of the multiplicity of realities naturally inherent in human beings. The article presents ways of conceptual consideration of the phenomenon of post-truth in the framework of correlating various historically significant evolutionary states of an individual, differing in the motivation of communicative activity. Four such states (Homo Mythicus, Homo Ludens, Homo Historicus, Homo Novus) are consistently demonstrated by the conditions of social development, but there is no clear idea to which of these types a person of a particular historical period or socio-political group can be attributed to. Post-truth is considered by the authors as a systemic phenomenon, that is a consequence of the relationship between the elements of three social processes. These include: a) gamification of existence, requiring the individual to participate in everyday experience of the plurality of surrounding realities; b) neuroticisation of social life due to high information pressure; c) the transformation of the media, that is expressed in the increased interdependence of the functions of information, entertainment and ideological influence. The authors propose a method for analysing post-truth addressees through the correlation of historically significant evolutionary states of an individual, that differ in the way of motivating communicative activity.

On the continuum spectra of the oscillation exponents of linear homogeneous differential systems
Authors: Stash Aydamir Kh.
Published: March 2023

The research subject of this work is at the junction of two sections of the qualitative theory of differential equations, namely: the theory of Lyapunov exponents and the theory of oscillation. In this paper, we study the spectra (i. e., sets of different values on nonzero solutions) of the exponents of oscillation of signs (strict and nonstrict), zeros, roots, and hyperroots of linear homogeneous differential systems with coefficients continuous on the positive semiaxis. For any n≥2, the existence of an n-dimensional differential system with continuum spectra of the oscillation exponents is established. For even n, the spectra of all the oscillation exponents fill the same segment of the numerical axis with predetermined arbitrary positive incommensurable ends, and for odd n, zero is added to the indicated spectra. It turns out that for each solution of the constructed differential system, all the oscillation exponents coincide with each other. When proving the results of this work, the cases of even and odd n are considered separately. The results obtained are theoretical in nature, they expand our understanding of the possible spectra of oscillation exponents of linear homogeneous differential systems.
La interpretación constitucional como caso especial de la interpretación jurídica
Authors: Portocarrero Quispe Jorge Alexander
Published: March 2023

Interpretación jurídica e interpretación constitucional son dos de los temas sobre los que más se ha escrito e investigado en los últimos años en el ámbito de la teoría jurídica. Sin embargo, no parece claro si estas categorías son equivalentes o si, en alguna medida, existe una diferencia o cualificación entre ellas ¿Interpretar normas constitucionales es indistinguible de la interpretación de normas infra constitucionales? ¿Son los métodos de aplicación para normas legales los mismos que aquellos a ser empleados para aplicar normas constitucionales? Mientras que algunas teorías equiparan la interpretación de normas constitucionales a la interpretación de normas legales, otras teorías plantean desarrollar una metodología de interpretación propia para las normas constitucionales. La importancia de abordar la relación entre interpretación jurídica e interpretación constitucional radica en que, si la interpretación constitucional se diferencia de la interpretación jurídica en general, entonces será posible sostener que la metodología tradicional, basada en cánones de interpretación y la subsunción, es insuficiente para interpretar la constitución. El presente artículo busca estructurar un argumento en favor de la especialidad de la interpretación constitucional, sin que ello implique desvincularla totalmente de la teoría general de la interpretación jurídica.
Injusticia epistémica
Authors: Santamaría Diana Latova
Published: March 2023

La conceptualización por parte de Miranda Fricker de las situaciones de injusticia epistémica en 2007 ha promovido la discusión acerca de este tipo de problemáticas en áreas como la epistemología política y la filosofía social. A pesar de que han proliferado los trabajos teóricos en torno a los diversos tipos de injusticia epistémica, parece que se trata de una construcción que no ha tenido calado en el ámbito iusfilosófico. En este trabajo se pretende ofrecer un mapa conceptual de la teoría de la injusticia epistémica, a través, fundamentalmente, del estudio de la obra de Fricker y con la ayuda de la literatura secundaria elaborada a raíz de su publicación. De esta forma, se tratará de acercar esta construcción teórica al ámbito del Derecho, poniendo sobre la mesa ciertos aspectos en que esta puede resultar útil, al tiempo que se plantean algunas posibles incógnitas acerca de la misma.

Screen Time and Dry Eye Disease During Distance Learning among the Class of 2019 Medical Students at a University in Jakarta, Indonesia
Authors: Bernadette Karen , Rasyid Meriana
Published: March 2023

Highlights:

There is a correlation between screen time and dry eye disease among medical students due to distance learning during the pandemic.
This study’s findings can lead researchers to conduct further studies to investigate and prevent DED.

 
Abstract:
Dry eye disease (DED), also known as dry-eye syndrome, is commonly caused by a lack of tears or excessive evaporation. It affects 334 million people worldwide. According to global epidemiological research, the DED prevalence in adults and the elderly is roughly 5-50%. Research has revealed that DED prevalence and epidemiology are more typically connected to aging. However, extended exposure to digital screens is an external DED risk factor to be aware of, especially in this digital technology era and amidst the COVID-19 pandemic. These two situations are expected to increase the number of DED sufferers in the younger age groups, such as elementary, high school, and university students. The ongoing COVID-19 pandemic has compelled a shift in learning and teaching methods in order for education to proceed. However, the digitization era and the COVID-19 pandemic can double the DED risk, particularly among medical students. This study’s objective was to determine how remote learning affected DED prevalence among the class of 2019 medical students at Universitas Tarumanagara, Jakarta, Indonesia, in the COVID-19 pandemic. Data were collected from 144 respondents using a Google Forms questionnaire. According to the statistical test results, there was a 2.4-fold increase in screen time during the COVID-19 pandemic compared to the pre-pandemic period. The results demonstrated a significant relationship between screen time and DED among the class of 2019 medical students at Universitas Tarumanagara. These findings are predicted to be of interest to academics and students, as their frequent engagement with computer displays and smartphones will continue to increase due to technological advancements. Furthermore, researchers may use the findings as a reference in conducting DED-related research.

Highlights:

Anxiety is an important morbidity among visually impaired older adults.
There is potential for stakeholders to specifically channel their interventions towards particular IVI domains in order to reduce anxiety prevalence.

 
Abstract:
Visual impairment is a significant morbidity among adults globally. It has negative impacts on work force participation and productivity, as and well as higher depression and anxiety disorder rates. In the case of older adults, vision impairment can contribute to social isolation and a greater likelihood of early entry into nursing or care homes. This hospital-based, cross-sectional study was designed to determine anxiety disorder’s prevalence among the study population and which Impact of Visual Impairment (IVI) domain is most correlated with anxiety disorder. The study was carried out at the Ophthalmology Clinic of the Ekiti State University Teaching Hospital, Ado Ekiti, Nigera. Questionnaires were used to collect information from 115 respondents. Information sought included sociodemographic information, anxiety status, and visual impairment’s impact on daily functions. The Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety disorder, while the IVI scale was used to assess the impact of visual impairment. The IVI scale is an instrument used for determining the impact of visual impairment under three domains: (reading and accessing information, mobility and independence, and emotional well-being). Anxiety disorder was detected in 10.4% of all the respondents, and the IVI’s mobility and independence domain of IVI was most strongly correlated with anxiety disorder.

Published: March 2023

Introduction: COVID-19 prevention is currently a major concern for WHO, especially administering the COVID-19 vaccine. However, there are still several problems underlying the achievements of the vaccine administration program in Indonesia, especially the administration of the COVID-19 vaccine to children aged 6-11 years. This study aimed to the relationship between parental knowledge and anxiety levels in implementing the COVID-19 vaccination program for children aged 6-11 years in Lamongan, Indonesia.
Method: This study used a cross-sectional design involving a total of 195 respondents. The research was conducted in Lamongan by measuring the level of knowledge and anxiety level of parents in administering the COVID-19 vaccine. The researcher used an instrument of a knowledge level questionnaire and the Hamilton Anxiety Rating Scale (HARS) which had been tested for validity and reliability, Data were analyzed using pearson correlation test with SPSS.
Results: The results showed that 42.6% had sufficient knowledge and only a small proportion of 24.6% had good knowledge. The level of anxiety shows that 49.7% is in the level of severe anxiety and 4.6% is in the level of mild anxiety. Parents with low levels of knowledge also have an impact on severe levels of anxiety. The results of the Pearson correlation test analysis show of sig 2-tailed = 0.002, which means that between the variable parental knowledge and the variable level of anxiety has a significant relationship with the value of the correlation coefficient = 0.223.
Conclusions: There is a relationship between the level of knowledge and the anxiety level of parents in administering the COVID-19 vaccine to children aged 6-11 years. Health education related about the benefits and impacts of giving the COVID-19 vaccine needs to be conveyed clearly to the public.

The role of human milk fats in shaping neonatal development and the early life gut microbiota
Authors: Seki David , Errerd Theresa , Hall Lindsay J.
Published: March 2023

Human breast milk (HBM) is the main source of nutrition for neonates across the critical early-life developmental period. The highest demand for energy is due to rapid neurophysiological expansion post-delivery, which is largely met by human milk lipids (HMLs). These HMLs also play a prebiotic role and potentially promote the growth of certain commensal bacteria, which, via HML digestion, supports the additional transfer of energy to the infant. In tandem, HMLs can also exert bactericidal effects against a variety of opportunistic pathogens, which contributes to overall colonisation resistance. Such interactions are pivotal for sustaining homeostatic relationships between microorganisms and their hosts. However, the underlying molecular mechanisms governing these interactions remain poorly understood. This review will explore the current research landscape with respect to HMLs, including compositional considerations and impact on the early life gut microbiota. Recent papers in this field will also be discussed, including a final perspective on current knowledge gaps and potential next research steps for these important but understudied breast milk components.
Theoretical and experimental studies of the electrical properties of electrical contact gasket for the graphitizing of electrode preparations in direct heating furnaces
Authors: Karvatskii Anton , Mikulionok Іgor , Leleka Serhii , Vytvytskyi Victor
Published: March 2023

The article presents the results of theoretical and experimental studies of specific contact electrical resistance (SCER) and specific electrical resistance (SER) of electrical contact gaskets (ECG) made of thermally expanded graphite (TEG) and intended for their placement on the ends of electrode blanks before their graphitization in direct heating furnaces – furnaces Castner's. The obtained data of SCER “graphite–gasket–graphite” and SER (or electrical conductivity) of the ECG material are needed to minimize the energy consumption of the graphitization process using numerical modeling of the thermoelectric state of Castner's furnaces in order to develop energy-efficient regulations for their operation.

The method of two samples was used for the experimental determination of the SCER, and the theoretical-experimental approach was used for the study of the SER, which makes it possible to exclude the influence of the contact resistance between the experimental sample and the electrodes for supplying the electric current on the value of the measured quantity and is based on the solution of the inverse coefficient problem of electrical conductivity (ICPE) using experimental data obtained during the SCER study.

A mathematical formulation of the ICPE was formulated, a numerical method and an algorithm for its solution were developed, and a study of the SER of the TEG at different values of temperature and pressure was carried out.

Determination of SCER and SER was carried out for ECG material with an initial density of 1000 kg/m3 in the temperature range up to 250 °С under different pressures in the range of up to 1.75 MPa. The results of these studies are presented in the form of two-parameter dependences on pressure and temperature with extrapolation up to 3000 °C. The measurement error of SCER and SER by the specified methods is estimated to be within 4–5% in the intervals of temperature change up to 250 °С and pressure up to 1.75 MPa.

The obtained SCER and SER dependences for the ECG material are needed to perform a numerical analysis of the thermoelectric state of Castner's furnaces in order to develop rational graphitization regulations.

Introduction. Selected dietary components are crucial for a properly functioning thyroid gland. Therefore a healthy and balanced diet is  crucial for treating patients with Hashimoto's disease.
Aim. This study aims to evaluate the dietary habits of women suffering from autoimmune thyroiditis.
Material and methods. A questionnaire study was conducted in a group of 58 women with Hashimoto's disease and among 42 women without autoimmune thyroiditis using the Food Frequency Questionnaire (FFQ-6). To assess compliance with the normal distribution, we used the Shapiro-Wilk test. The comparative assessment was made using the Student's t-test and Mann-Whitney test. The Chi-square test was used to assess the relationship between the response and the group. A p-value of less than 0.05 was considered significant.
Results. The study showed no significant differences in dietary habits between the two groups. Only 29% (n=15) of women with HT declared daily consumption of fruits vs 31% (n=12) in the control group (p=0.3800), and only 2% (n=1) declared consuming berries daily vs. 5% (n=2), (p=0.5270). The consumption of the recommended several portions of vegetables per day was declared by only 22% (n=11) of women with HT vs 28% (n=11) in the control group (p=0.3983). 42% (n=24) of women with HT vs 38.5% (n=16) of controls reported eating cruciferous vegetables several times a week (p=0.8241). 14% (n=8) of women with HT vs 19% (n=8) of women in the control group declared daily consumption of green leafy vegetables (p=0.3653). Most people in the study group consume nuts and seeds several times a month, and those in the control group several times a week. Most HT respondents also declare not to consume the recommended amount of fish.
Conclusions. The diet of patients with Hashimoto's disease does not differ significantly from that of non-Hashimoto's disease patients. Considering the study results and current scientific knowledge, it seems necessary to undertake educational activities for patients with Hashimoto's disease to increase patient awareness of the impact of diet on the course of the disease.
Revisiting pathogen transmission in epidemiological models and its role in the disease-diversity relationship

With the rising frequency of pathogen spillover worldwide, wildlife disease dynamics have received increased attention. There are many possible pathway a pathogen can invade and spread through a host population, and the assumed transmission model used to capture disease propagation can influence predictions of pathogen net reproductive success (R0), determining the outbreak dynamics. We synthesize a comprehensive overview of these models and overarching implications, using bovine Tuberculosis (Mycobacterium bovis) as a case study. We unify sub-models from the disease ecology literature and clarify the biological motivation behind these models and resulting ecological dynamics. We warn readers of pitfalls regarding the relative orders of the transmission parameters and reiterate that the contact rate determines the transmission model and thus defines key dynamical properties of an outbreak. Transmission in wildlife is linked to ecosystem and human health, and host community structure can mediate pathogen spread. We link these models with disease-biodiversity theories, by considering the role of host diversity in disease transmission, contributing to the debate on the effect of biodiversity and on disease outbreak potential. We decompose the various mechanisms of transmission in a stepwise process, and provide the reader a guide for modelling pathogens in both single-host and multi-host systems.

Indoor localization is an active area of research dominated by traditional machine-learning techniques. Deep learning-based systems have shown unprecedented improvements and have accomplished exceptional results over the past decade, especially the Transformer network within natural language processing (NLP) and computer vision domains. We propose the hyper-class Transformer (HyTra), an encoder-only Transformer with multiple classification heads (one per class) and learnable embeddings, to investigate the effectiveness of Transformer-based models for received signal strength (RSS) based WiFi fingerprinting. HyTra leverages learnable embeddings and the self-attention mechanism to determine the relative position of the wireless access points (WAPs) within the high-dimensional embedding space, improving the prediction of user location. From an NLP perspective, we consider a fixed order sequence of all observed WAPs as a sentence and the captured RSS value(s) for every given WAP at a given reference point from a given user as words. We test our proposed network on public and private datasets of different sizes, proving that the quality of the learned embeddings and overall accuracy improves with increments in samples.

The presence of copper in distilled sugar cane spirits, especially cachaça produced in alembics, has impeded the marketing of this product. Red mud (RM) is a residue obtained from alumina production. It contains a high concentration of metal oxides and is very alkaline. The RM was dried at 100 oC and sifted through a 150-micron sieve. The sample was characterized by B.E.T. nitrogen adsorption, scanning electron microscopy-energy-dispersive X-ray (SEM-EDX) and Atomic Absorption Spectrometry (A.A.S.). The textural parameters indicate that the total surface area (S.T.) was 21.9 m2g-1, and the total volume pore (V.T.) was 0.09 cm3g-1. The RM (1 g) was stirred for two hours with a 1.0 L cachaça sample containing 9.39 mg of copper L-1 and filtered under atmospheric pressure. The concentration of copper ions detected in the filtrate was 0.00 mg L-1. No copper ions were retained when the cachaça was filtered through the RM under high pressure without stirring prior to filtration.

Azolla (Azolla microphylla) is a potential livestock feed due to its fast-growing and relevant nutrient content. Quail farming generates manure as a by-product that can be used as fertilizer to support plant growth. This study aims to determine the dose effect of fermented quail manure on the growth rate of Azolla, as well as the nutritional content of the resulting Azolla biomass. The data were obtained through observation in 20 Azolla culture ponds according to the design method throughout the research for the Azolla growth rate parameters and laboratory tests to analyze manure and Azolla proximate content at the end of the study. The results showed that treatment of 50, 100 and 150 g m-2 of quail manure gave similarly good effects on the Azolla growth parameters, indicating that the application of quail manure can significantly increase the production of Azolla biomass in culture ponds. The resulting Azolla biomass from all treatments gave a value of 93% to 95% moisture content, 18% to 19% ash content, 36% to 42% protein, 20% to 37% fiber, 2.8% to 4% fat and 5% to 6% carbohydrates. Looking at the big picture, therefore, 100 g m-2 manure treatment is considered the most optimal among the rest. Based on the result obtained, this study can provide an overview of the dose of quail manure that can be used to support the growth of Azolla.

Sintrong is an Indonesian indigenous vegetable with leaves used for vegetables, digestive disorders, and burns. Changes in the environment due to an increase in temperature affect the growth and quality of sitrong, and its existence in the nature is threatened. This study aims to obtain information about the effect of exposure to high temperatures on the physiological character and flavonoid content of indigenous sintrong vegetables and obtain accession of sintrong, which can be developed as a functional vegetable. The Nested randomized group design was applied with two factors, temperature differences as the main plot and accession as a second plot. Four replications were conducted for each accession in the Cikabayan experimental garden of IPB. The results showed that exposure to high temperatures up to 32 °C increased the speed of flowering age, which was 4.76% and 7.14% faster and showed a high wilting rate of 36.66%, but decreased leaf area index up to 30.30% and 42.42% at the conditions above ambient temperature exposure (control). Flavonoid content did not show any effect due to exposure to high temperatures. The flavonoid content reached 1695.38 and 1834.83 mg QE 100 g-1. Bogor 1 accession showed the best performance so that the plants can be developed for functional vegetables. Based on the research findings, sintrong should be harvested earlier before flowering to obtain high leaf production and good-quality vegetables.
