Актуальность исследования обусловлена необходимостью получения новых знаний об обогатимости золотосодержащих руд и необходимостью развития ресурсной базы Российской Федерации, а именно вовлечения объектов недропользования в хозяйственный оборот. Цель: исследование по переработке малосульфидной золото-кварцевой руды с применением комплексной технологии обогащения минерального сырья. Объект: золотосодержащая руда со средним содержанием золота 11,88 г/т. Содержание серебра незначительное - 2,43 г/т. Основными рудными минералами в образце являются пирит и пирротин. Среднее содержание этих минералов в руде, по данным минералогического и рентгеноструктурного анализа, составило около 6 % (суммарно). Основными породообразующими минералами исходной руды являются: кварц - 60,1 %; кварц-хлорит-слюдяные агрегаты - 3,8 %; карбонаты - 7,1 %. Методы. Методология исследования базировалась на теоретических основах обогащения полезных ископаемых. Изучение вещественного состава руды и продуктов обогащения было выполнено с использованием химического, пробирного, термического, спектрометрического методов, а также атомно-эмиссионной спектрометрии и других методов. Изучение обогатимости проводили методами гравитационного и флотационного обогащения, а именно: GRG тест, стадиальный тест института ТОМС (Россия) (определение оптимальной крупности измельчения руды и количества стадий обогащения), моделирование извлечения золота в цикле измельчения, определение оптимальной степени помола, исследование выбора флотационных реагентов, исследование кинетики процесса и проведение комплекса технологических исследований. Результаты. Установлено, что извлечение золота при проведении GRG-теста составило 72,75 % при выходе общего концентрата 1,34 % и его содержании 664,78 г/т. При этом содержание золота в хвостах составило 3,29 г/т. Стадийные испытания показали, что при переработке руд только гравитационным способом целесообразно использовать двухстадийную схему. Первая стадия находится в цикле измельчения при крупности руды 60-70 % и вторая стадия - при конечной крупности насыпи классификации 90 % класса -0,071 мм. Центробежная сепарация как свободная операция извлечения золота в цикле измельчения работает эффективно. Получен концентрат с содержанием золота 2426 г/т с выходом 0,31 % и извлечением 63,74 %. Обогащение дробленых до 90 % хвостов первой очереди класса -0,071 мм на обогатительной фабрике KC-CVD (моделирование) позволило извлечь золото в общий гравиоконцентрат (KC-MD+KC-CVD) 87,25 % при содержании выхода фугата 22,63 %. Содержание золота в хвостах составило 1,97 г/т. The relevance of the research is caused by the necessity to acquire new knowledge about the enrichment of gold-bearing ores and the need to develop the resource base of the Russian Federation, namely involve subsoil use objects in economic circulation. The purpose of the study is to study the processing of low-sulfide gold-quartz ore using an integrated technology for the enrichment of mineral raw materials. Object: gold ore raw materials with an average gold grade of 11,88 g/t. The silver content is negligible - 2,43 g/t. The main ore minerals in the sample are pyrite and pyrrhotite. The average content of these minerals in the ore, according to mineralogical and X-ray diffraction analysis, was about 6 % (in total). The main rock-forming minerals of the original ore are: quartz - 60,1 %; quartz-chlorite-mica aggregates - 3,8 %; carbonates - 7,1 %. Methods. The research methodology was based on the theoretical foundations of mineral processing. The study of the material composition of the ore, and enrichment products, was carried out using chemical, assay, thermal, spectrometric methods, as well as atomic emission spectrometry and other methods. The study of washability was carried out by the methods of gravity and flotation enrichment, namely: GRG test, stage test of the Institute TOMS (Russia) (determination of the optimal size of ore grinding and the number of enrichment stages), modeling of gold extraction in the grinding cycle, determination of the optimal degree of grinding, study of the choice of flotation reagents, study of the kinetics of the process and the implementation of a complex of technological studies. Results. It was found that the gold recovery when performing the GRG test was 72,75 % with a total concentrate yield of 1,34 % and a content of Au 664,78 g/t. At the same time, the gold content in the tailings was 3,29 g/t. A stage test showed that for ore processing only by gravity technology, it is advisable to use a two-stage scheme. The first stage is in the grinding cycle with the ore size of 60-70 % and the second stage - with the final size of the discharge of the classification 90 % size of -0,071 mm. Centrifugal separation, as a free gold recovery operation in a grinding cycle, works efficiently. A concentrate with a gold content of 2426 g/t was obtained with an output of 0,31 % and an extraction of 63,74 %. The enrichment of the first stage tailings crushed to 90 % size of -0,071 mm at the KC-CVD concentrator (modeling) made it possible to extract gold into a total gravity concentrate (KC-MD+KC-CVD) of 87,25 % with a concentrate yield of 22,63 %. The gold content in the tailings was 1,97 g/t. The results of gravity and flotation concentration of the original ore indicate the feasibility of using a combined gravity-flotation technological scheme. In a closed experiment of the initial ore beneficiation according to the gravity-flotation scheme at a natural pH of the pulp (without adding acid), the following products were obtained: gravity concentrate with a gold content of 2426 g/t at a yield of 0,31 % and an extraction of 64,06 %; flotation concentrate (after the II cleaning) with a gold content of 122 g/t with a yield of 2,90 % and recovery of 33,01 %; the total gold recovery in the gravity-flotation concentrate was 94,07 % with a yield of 3,21 % and Au content of 345,87 g/t, the gold content in the flotation tailings was 0,72 g/t.

When it comes to evaluating the causal effect of public policies on corporate performance, most studies tend to focus exclusively on targeted firms, as if these firms have no relationship to the rest of the economy. Yet, public policies are highly likely to influence nontargeted firms indirectly due to the relationships they have with targeted firms. This paper aims to fill this gap by evaluating the indirect causal effect of a new French cluster-innovation policy on the financial and employment outcomes of non-targeted companies. To do so, it focuses on French Technological Research Institutes, which are science-industry collaborations based on technology platforms that bring together SMEs, large companies, universities, and public research bodies with the goal of accelerating the transfer of knowledge towards firms and generating spillovers (indirect effects) inside and outside the scheme. Based on the literature on spillover effects and agglomeration economies, it can be assumed that industry-specific spillovers tend to be spatially concentrated. By comparing a non-targeted firm located in the NUTS-3 regions within which the policy was implemented (referred to as "treated regions"), to a non-targeted firm outside of these "treated regions", using a difference-in-differences method with fixed effects applied to panel data (2008– 2016) combined with a double matching at the NUTS-3 region and firm level, we find that non-targeted firms located in the "treated regions" significantly improve their financial performance (turnover, financial autonomy) compared to control firms located in the NUTS-3 control regions. The dynamics of employment outcomes are ambiguous. A negative significant effect is observed on the proportion of managers at the beginning of the policy and a positive significant effect is noted later, at the end of the period of observation. An analysis of the dynamics of the effects indicates that performance does not improve immediately after the policy, but later in time.; Lorsqu'il s'agit d'évaluer l'effet causal des politiques publiques sur la performance des entreprises, la plupart des études ont tendance à se concentrer exclusivement sur les entreprises ciblées, comme si ces entreprises n'avaient aucune relation avec le reste de l'économie. Pourtant, il est fort probable que les politiques publiques influencent indirectement les entreprises non ciblées en raison des relations qu'elles entretiennent avec les entreprises ciblées. Cet article vise à combler cette lacune en évaluant l'effet causal indirect d'une nouvelle politique française de cluster-innovation sur les résultats financiers et d'emploi des entreprises non ciblées. Pour ce faire, il se concentre sur les Instituts de Recherche Technologique français, qui sont des collaborations science-industrie basées sur des plateformes technologiques qui rassemblent des PME, des grandes entreprises, des universités et des organismes de recherche publics dans le but d'accélérer le transfert de connaissances vers les entreprises et de générer des retombées (effets indirects) à l'intérieur et à l'extérieur du dispositif. Sur la base de la littérature sur les effets d'entraînement et les économies d'agglomération, on peut supposer que les retombées sectorielles ont tendance à être concentrées dans l'espace. En comparant une entreprise non ciblée située dans les régions NUTS-3 (départements Français) dans lesquelles la politique a été mise en œuvre (appelées "régions traitées"), à une entreprise non ciblée en dehors de ces "régions traitées", en utilisant une méthode de différence dans les différences avec effets fixes appliquée à des données de panel (2008- 2016) combinée à un double appariement au niveau de la région NUTS-3 et de l'entreprise, nous constatons que les entreprises non ciblées situées dans les "régions traitées" améliorent significativement leurs performances financières (chiffre d'affaires, autonomie financière) par rapport aux entreprises témoins situées dans les régions de contrôle NUTS-3. La dynamique des résultats en matière d'emploi est ambiguë. Un effet significatif négatif est observé sur la proportion de cadres au début de la politique et un effet significatif positif est noté plus tard, à la fin de la période d'observation. Une analyse de la dynamique des effets indique que les performances ne s'améliorent pas immédiatement après la politique, mais plus tard dans le temps.

El presente trabajo de investigación representa el primero de una serie de ensayos, con módulos fotovoltaicos que han sido desarrollados en el Centro de Investigaciones energéticas, medioambientales y tecnológicas (C.I.E.M.A.T.), en la ciudad de Madrid, España. Un módulo fotovoltaico (FV) viene definido eléctricamente por su curva de intensidad-voltaje (I-V). Esta curva depende básicamente de la irradiancia solar incidente. El presente estudio consistió en la medición de las curvas I-V para un módulo fotovoltaico de silicio monocristalino utilizando como herramienta el trazador de curvas I-V “PVPM 1000 CX”, donde el módulo FV se midió a varias condiciones de laboratorio, encontradas en la etapa de operación: a) manteniendo una radiación solar constante de 857 W/m2 en el módulo FV para cinco temperaturas diferentes de 38°C, 40 °C, 44,9 °C, 49,65 °C y 53,4 °C; y b) manteniendo una temperatura constante de 51,4 °C en el módulo para cuatro radiaciones solares diferentes de 857 W/m2, 596 W/m2, 727 W/m2 y 784 W/m2. Se han elaborado las curvas I-V, se ha analizado el comportamiento del módulo con las condiciones impuestas en lo que respecta a la tensión de circuito abierto (Voc) y la intensidad de corto circuito (Isc). Los resultados obtenidos de las mediciones reproducen la tradicional forma de las curvas I-V para las nueve condiciones de laboratorio, también se demuestra que en ninguno de los ensayos se ha sobrepasado los valores de condiciones estándar (Isc) y (Voc) del módulo fotovoltaico.

The metal sulfide precipitation process is a widely studied technology used to recover metals or remove pollutants from different aqueous sources. However, the conventional clarification stage used to separate the generated precipitates cannot effectively remove them from recovered solutions. Taking this into account, the current study focuses on developing a new separation method applied in metal sulfide precipitates, based on a membrane filtration process. Different operating conditions and metal concentration in the feed solution were evaluated for the separation of copper sulfide precipitates formed from synthetic cyanide solutions in ceramic microfiltration membranes. Results showed attractive values of flux and copper recovery. Flux results ranged between 0.9 L/m2s and 1.2 L/m2s for copper concentrations above 500 mg/L, and copper recoveries resulted closer to 100% at the determined optimal operating conditions (4.5 pH, 120% NaHS stoichiometric dosage, and 2 bar feed pressure). These flux values decreased up to one order of magnitude for diluted copper concentrations, due to a change of aggregation capacity of precipitates. This study has demonstrated that the membrane filtration process can be a suitable alternative for the conventional gravitational clarification, promoting better performance results in terms of equipment capacity, metal recovery, and process safety.

This paper describes a dataset consisting of 47 hyperspectral-reflectance measurements of plastic litter samples. The plastic litter samples include virgin and real samples from the Port of Antwerp. They were measured in dry conditions in the Flemish Institute for Technological Research (VITO) calibration facility, and a selection of the samples were also measured in wet conditions and submerged in a water tank at Flanders Hydraulics. The construction on top of the tank allowed us to submerge the plastics and keep sediments in suspension. The spectral measurements were performed using an Analytical Spectral Devices (ASD) FieldSpec 4 and a Spectral Evolution (SEV) spectrometer. The datasets are available on the 4TU.ResearchData open-access repository (ASD dataset: https://doi.org/10.4121/12896312.v2, Knaeps et al., 2020; SEV dataset: https://doi.org/10.4121/uuid:9ee3be54-9132-415a-aaf2-c7fbf32d2199; Garaba et al., 2020).

The dairy industry is one of the most important components of the world food system, and is undergoing dramatic change at the current time. It is highly probable that within ten years, the global dairy industry will be scarcely recognizable from its current form. So, attitudinal changes of consumers also vary in the past 2 decades. Attitude of the consumers will continuously change owing to the technological research and innovation in the dairy industry. So, this research emerged and aimed to examine the consumer attitude towards dairy products in Erode district of Tamilnadu, India. Because Erode district shows its more involvement in agriculture along with dairy products. The researcher has selected 132 consumers who have using the dairy products in different way of usage like milk, butter, butter milk, ghee, palkova, etc. The changes in their attitude would find from a structured questionnaire which consists of demographic and usage of dairy products, and their attitude on dairy products. The collected data were subdued into tables and charts with the help of MS-excel and SPSS 22.0. This research has found the results as most of the respondents were urban area consumers of dairy products, purchasing frequently Aavin products and they were using dairy products for 5 to 10 years in the study area.

The connectivity aspect of the Internet of Things (IoT) has received most of the attention over the last years and has led to mature solutions for IoT‐connected devices. This chapter focuses on the opportunities that the provision of streams of real‐time data from a large number of IoT‐connected devices with sensing capabilities provides for monitoring, optimization, management, and intelligent service provision in modern socio‐technical systems. In such technical systems, which are often called cyber‐physical systems (CPS), real‐time computing elements and physical systems interact tightly. The chapter summarizes and analyzes the technological research and innovation (R&I) priorities in the European Union and the United States in the IoT and CPS sectors. It presents R&I themes having a large potential for EU–US collaboration. The chapter gives key recommendations for promising, concrete EU–US collaboration actions on the technology themes that were developed within the PICASSO project.

BACKGROUND: Obesity occurs due to a positive energy imbalance, leading to the expansion of adipose tissue. This phenomenon triggers a chronic low-grade inflammatory state, which is associated with comorbidities development. It is, therefore, of great interest to investigate new counteracting nutritional strategies. In this regard, polyphenol-rich Chilean native fruits, Aristotelia chilensis (Maqui) and Berberis microphylla (Calafate), and also the non-Chilean Vaccinium corymbosum (Blueberry), have been associated with antioxidant and anti-inflammatory features. OBJECTIVE: To evaluate Maqui, Calafate, and Blueberry aqueous extracts treatments on the pathogenic response of human activated macrophages and visceral adipocytes. METHODS: THP-1 monocyte human cell line and differentiated human visceral preadipocytes were activated (with lipopolysaccharide and TNF-α, for 48 and 24 h, respectively), and treated with the aqueous extracts. Inflammation and oxidative stress markers were assessed. RESULTS: Lower NO and IL-6 secretion, and inhibited apoptosis in activated macrophages, were observed. Also, decreased gene expression of MCP-1 and secretion of IL-6, inhibited apoptosis, and increased levels of GSH in activated adipocytes were detected. CONCLUSIONS: Maqui, Calafate, and Blueberry extracts showed anti-inflammatory and antioxidant responses in human macrophages and adipocytes.

Background and Objective This study was aimed to elucidate the molecular mechanism of Momordica charantia (MCh), along with a standard drug prednisolone, in a rat model of colitis induced by trinitrobenzene sulfonic acid (TNBS). Methods After the induction of the experimental colitis, the animals were treated with MCh (4 g/kg/day) for 14 consecutive days by intragastric gavage. The colonic tissue expression levels of C-C motif chemokine ligand 17 (CCL-17), interleukin (IL)-1β, IL-6, IL-23, interferon-γ (IFN-γ), nuclear factor kappa B (NF-kB), and tumor necrosis factor-α (TNF-α), were determined at both mRNA and protein levels to estimate the effect of MCh. Besides, colonic specimens were analyzed histopathologically after staining with hematoxylin and eosin. Results The body weights from TNBS-instigated colitis rats were found to be significantly lower than untreated animals. Also, the IFN-γ, IL-1β, IL-6, Il-23, TNF-α, CCL-17, and NF-kB mRNA and protein levels were increased significantly from 1.86-4.91-fold and 1.46-5.50-fold, respectively, in the TNBS-instigated colitis group as compared to the control. Both the MCh and prednisolone treatment significantly reduced the bodyweight loss. It also restored the induced colonic tissue levels of IL-1β, IL-6, IFN-γ, and TNF-α to normal levels seen in untreated animals. These results were also supported with the histochemical staining of the colonic tissues from both control and treated animals. Conclusion The presented data strongly suggests that MCh has the anti-inflammatory effect that might be modulated through vitamin D metabolism. It is the right candidate for the treatment of UC as an alternative and complementary therapeutics.

To reconstruct the technological methods and technical achievements of Northern Selkup blacksmiths, the components of the Northern Selkup shaman costume, which is composed of ferrous metal, were studied using metallographic analysis methods. The materials were found in two graves in a Kikki-Akki burial ground from the XVII–XVIII centuries (Western Siberia, Taz river). It was found that the basic raw materials for production were unevenly carbonized steel and soft iron; high-carbon steel was also found in rare instances, which was most likely received by Northern Selkup blacksmiths from Russia. The iron items of the shaman costume were forged by professional blacksmiths who possessed complex technological skills and production equipment.

En este artículo de investigación científica y tecnológica se exponen resultados de dos investigaciones relacionadas con las identidades discursivas y las operaciones de construcción semiótica y discursiva de la pintura mural del Templo de Santa Bárbara de Tunja. A partir de la perspectiva teórica y metodológica de la semiótica de la Escuela de París, se analizó la relación entre los colores de las pinturas y las identidades discursivas enunciadas en los murales del templo citado. Cabe destacar que las identidades de los sujetos y colectivos culturales se proponen como signos discursivos multidimensionales, constituidos por su cognición, axiología, pasiones y sistemas semióticos, entre ellos, los cromáticos. El análisis semiótico del color en la pintura mural permitió concluir sobre la enunciación de identidades discursivas que hibridan formas de vida católicas, de origen europeo occidental, y nativas americanas. De igual manera, se coligió que las significaciones del color identificadas, que datan del siglo XVII, se mantienen hasta la actualidad en el universo cultural de ubicación del espacio de ritual religioso.

Purpose: This study conducts a systematic review of policy reforms for the evaluation of scientific and technological research (E-STR) in China’s colleges. In doing so, it identifies changes to past policies, as well as the objectives and realizability of the most recent policy reform. Design/Approach/Methods: This study systematically reviews the contexts of E-STR policy reforms in China’s colleges post 2000 using three important related policy documents from 2003, 2013, and 2020 as samples. Research findings were obtained via content analysis. Findings: Unlike previous attempts, the most recent policy reform has incorporated the lessons learned while introducing highly targeted measures and a monitoring mechanism. Such reform should accelerate the promotion of major original scientific research in China’s colleges, enhance the contribution of scientific research to socioeconomic development, and strengthen support for the cultivation of undergraduate talents. Originality/Value: Initiated in the early part of 2000, China’s latest E-STR policy reform constitutes an important turning point in the initiative to burst the research bubble and return to the essence of innovation. It will drive China’s colleges to embark on a research path that places value on original innovation and contribution to socioeconomic development.

Cementitious materials have relevant applications related to the civil construction sector, such as concretes and mortars. However much of the existing technological research favors concrete, which makes mortar a still deficient material for research. The water / cement ratio is an extensively investigated parameter for concretes, however, it is still very little studied in mortar. The Abrams, Lyse and Molinari equations, for example, are consecrated in their application in concrete, but not yet evaluated for mortars, being a scientific gap. The objective of this work was to evaluate for the first time the effect of the water / cement ratio in mortars, using three different mixtures, in proportions of [1: 1: 6], [1: 2: 9] and [1: 0: 3] for cement: lime: sand combined with two different types of Portland cements. Based on these relationships the aforementioned equations investigating mortars were characterized. Mass consistency tests as well as mechanical resistance to compression and flexion test at 14 and 28 days as well as water absorption by capillarity and by immersion together with density measured in the hardened state were performed to verify the Abrams, Lyse and Molinari laws, and their possible validation for use in mortars. The results prove that the water / cement ratio considerably affects the evaluated technological properties and that the Abrams and Lyse equations are viable for application in mortars, just as they are applied to concretes. As for the Molinari equation, it requires mathematical modification, and the fresh mortars density.

By taking the projects which are carried out in the universities in Turkey and are funded by the Scientific and Technological Research Council (TÜBİTAK) as an output, the paper tries to estimate the knowledge production function of Turkey. In the study, an OLS analysis is made with cross-section data by utilizing the datum of state universities operating in Turkey at the NUTS III level. The dependent variable of the knowledge production function that is developed by using Cobb-Douglas production function is the annual R&D fund transferred to universities by TÜBİTAK for the projects. Other variables in the analysis are the annual R&D expenditures of universities, the number of academic staff, number of postgraduate students and the existence of Technology Transfer Office and/or Technopolis. According to the analysis results there is a positive and significant relationship between R&D fund, and postgraduate students and technology transfer offices/technopolis. However, the relationship between R&D expenditures and the R&D funds transferred to the universities is found to be statistically insignificant. A negative and insignificant relationship is found when R&D funds and academic staff are estimated together, but in the models in which academic staff is decoupled, the results differ.

The aim of this study is to review the opinions of principals and teachers on TUBITAK-4006 (Scientific and Technological Research Council of Turkey) science fairs which are organized in about 10.000 schools every year in Turkey. This study is a qualitative research and it is formed with phenomenological design. The study group is determined with criterion sampling method, and it comprises 10 teachers and 10 school administrators who have participated in TUBITAK-4006 science project fairs. The data are collected with a semi-structured interview form, and the interviews are carried out face to face. The data collected have been evaluated using content analysis method. As a result of the analysis, the viewpoints of the school administrators and teachers are presented in two themes and seven categories. For the both participant groups, the themes are analysed by categorizing them as the effects on teachers, the effects on students and parents. Besides, the suggestions category is indicated under one single title. According to the findings, all the participants stated that TUBITAK-4006 science project fairs are useful if carried out considering their purposes while they cause more harm when their objectives are disregarded.

Early childhood is a critical period for social-emotional development; during this period, the child's immediate family is the system with the greatest influence on his or her development. The parents' capacity to reflect on the children's ability to process and interact within a social environment, called parental reflective functioning (RF), is considered an important factor in protecting children from highly prevalent social-emotional difficulties and may have a strong influence on children's long-term development.To describe and analyze the relationships among parents' RF, the quality of the mother-father-child triadic interaction, and children's social-emotional difficulties.A nonexperimental, cross-sectional, correlational study was conducted. Fifty mother-father-child triads, each in a current relationship that included at least one child aged 12-36 months, were evaluated. Sociodemographic background, triadic interaction, parental RF, and social-emotional difficulties were assessed.Triadic interaction was found to have a significant effect on the child's social-emotional difficulties, explaining 9% of the variance. In addition, the mothers' RF had a significant influence on triadic interaction, explaining 19% of the variance. An exploratory finding showed that triadic interaction mediates the relationship between mothers' RF and children's social-emotional difficulties.La temprana niñez es un período crítico para el desarrollo socio-emocional; durante este período, el núcleo familiar del niño es el sistema con la mayor influencia en su desarrollo. La capacidad de los padres de reflexionar sobre la habilidad del niño de procesar e interactuar dentro del ambiente social, llamada la función reflexiva de los padres (RF), es considerada un factor importante en la protección del niño en cuanto a dificultades socio-emocionales altamente prevalentes y pudiera tener una fuerte influencia en el desarrollo del niño a largo plazo.

In dieser Zeit ist die Kernfamilie des Kindes das System mit dem größten Einfluss auf seine Entwicklung. Die Fähigkeit der Eltern zu reflektieren, inwiefern das Kind dazu in der Lage ist, ein soziales Umfeld zu verstehen und in ihm und zu interagieren, wird als elterliche Reflexionsfähigkeit (reflective functioning; RF) bezeichnet. Sie spielt eine wichtige Rolle darin, Kinder vor weit verbreiteten sozial-emotionalen Schwierigkeiten zu schützen und kann einen starken Einfluss auf ihre langfristige Entwicklung haben. ZIEL: Beschreibung und Analyse der Zusammenhänge zwischen der elterlichen RF, der Qualität der triadischen Mutter-Vater-Kind-Interaktion und der sozial-emotionalen Schwierigkeiten der Kinder. METHODE: Eine nicht experimentelle Korrelationsquerschnittsstudie wurde durchgeführt. 50 Mutter-Vater-Kind-Triaden, mit jeweils mindestens einem Kind im Alter von 12 bis 36 Monaten, wurden in die Analyse aufgenommen. Der soziodemografische Hintergrund, die triadische Interaktion, die elterliche RF und sozial-emotionale Schwierigkeiten wurden beurteilt. ERGEBNISSE: Es wurde festgestellt, dass die triadische Interaktion einen signifikanten Einfluss auf die sozial-emotionalen Schwierigkeiten des Kindes hat und 9% der Varianz aufklärt. Außerdem hatte die mütterliche RF einen signifikanten Einfluss auf die triadische Interaktion und klärte 19% der Varianz auf. Ein exploratives Ergebnis zeigte, dass die triadische Interaktion den Zusammenhang zwischen der mütterlichen RF und den sozial-emotionalen Schwierigkeiten der Kinder mediiert.三者間相互作用、親の内省機能と早期の社会・情緒的困難性 乳幼児期は、社会・情緒的発達において重要な時期である。つまりこの時期、乳幼児の直系家族が乳幼児の成長に多大なる影響をもたらすシステムなのである。社会環境内における物事の処理をしたり相互交流をしたりする乳幼児の能力を省みる親の能力−親の内省機能(RF)と呼ばれるもの−は、非常に多く見られる社会・情緒的困難性から乳幼児を防ぐための重要な要素と考えられる。そして、乳幼児の長期の発達に強い影響をもたらすであろうと考えられている。 目的: 親の内省機能、母親-父親−乳幼児の三者間相互作用、乳幼児の社会・情緒的困難性の関係性を説明し、分析する。 方法: 非実験的研究、横断研究、相関研究を実施した。少なくとも生後12ヶ月から36ヶ月の乳幼児が1人いる50組の母親-父親−乳幼児に対して査定をした。社会人口統計学の背景、三者間相互作用、親の内省機能と社会・情緒的困難性を評価した。 結果: 三者間相互作用は、乳幼児の社会・情緒的困難性に有意な影響があることが、9％の分散ということから判明した。さらに、母親の内省機能が三者相互交流に有意な影響があることが、19％の分散から判明した。探査的研究の結果は、三者相互作用は、母親の内省機能と乳幼児の社会・情緒的困難性の関係に介在することを示していた。.幼儿时期是社交情感发展的关键时期。在此期间, 儿童的直系亲属是对其发展影响最大的体系。父母反思儿童在社交环境中处理和互动水平的能力, 称为育儿反思功能 (RF)。它被认为是保护儿童免受高度普遍的社交情感困扰的重要因素, 并且可能对儿童的长期发展产生重大影响。 研究目的: 描述和分析父母的育儿反思功能、母亲-父亲-儿童三元互动、儿童社交情感障碍之间的关系。 研究方法: 开展了一项非实验性的、横断面、相关性研究。对50个母亲-父亲-儿童三元组进行了评估, 每组中至少包括一名12-36个月大的儿童。对社会人口背景、三元互动、育儿反思功能和社交情感障碍进行了评估。 研究结果: 我们发现三元互动对儿童社交情感障碍有显著影响, 解释了9%的差异。此外, 母亲反思功能对三元互动有显著影响, 解释了19%的差异。一项探索性的发现表明, 三元互动介导了母亲反思功能与儿童社交情感障碍之间的关系。.التفاعلات الثلاثية، الأداء التأملي للوالدين، والصعوبات الاجتماعية والعاطفية المبكر الملخص الطفولة المبكرة هي فترة حاسمة في النمو الاجتماعي والعاطفي؛ وخلال هذه الفترة، تكون الأسرة المباشرة للطفل هي النظام الذي له أكبر تأثير على نموه. وتعتبر قدرة الوالدين على التفكير في قدرة الأطفال على التفاعل في بيئة اجتماعية، والتي تسمى الأداء التأملي للوالدين، عاملا هاما في حماية الأطفال من الصعوبات الاجتماعية - العاطفية المنتشرة إلى حد كبير، وقد يكون لها تأثير قوي على نمو الأطفال على المدى الطويل. الهدف: وصف وتحليل العلاقات بين الوالدين، ونوعية التفاعل الثلاثي بين الأم والأب والطفل، والصعوبات الاجتماعية والعاطفية للأطفال. الطريقة: أجريت دراسة غير تجريبية ومقطعية. وتم تقييم خمسين مجموعة ثلاثية للأم والأب والطفل، كل في علاقة حالية شملت طفلاً واحداً على الأقل يتراوح عمره بين 12 و36 شهراً. وتم تقييم الخلفية الاجتماعية الديمغرافية، والتفاعل الثلاثي، والأداء التأملي الأبوي، والصعوبات الاجتماعية - العاطفية. النتائج: تبين أن التفاعل الثلاثي له تأثير كبير على الصعوبات الاجتماعية والعاطفية للطفل، مما يفسر 9٪ من التباين. وبالإضافة إلى ذلك، كان للأداء التأملي الأمهات تأثير كبير على التفاعل الثلاثي، حيث شرح 19 في المائة من التباين. وأظهرت نتيجة استكشافية أن التفاعل الثلاثي يتوسط العلاقة بين الأداء التأملي للأمهات والصعوبات الاجتماعية والعاطفية للأطفال.

Sound-producing organs generate acoustic signals that have a fundamental role in communication systems. In species exhibiting different biogeographic patterns, variations of these structures can explain a large part of interpopulation differences of their signals. Pleurodema thaul is an anuran with an extensive geographic distribution in Chile and presents an evident divergence in its acoustic signals among three genetic/bioacoustic groups (i.e. northern, central and southern). By means of classic histology and 3D-reconstructions, we study the geographic variation in the larynx of P. thaul males from these three groups. In addition, volumes of six laryngeal structures are used as predictors of acoustic characteristics of advertisement calls recorded in previous studies for the same subjects used in the current study. After removing the effect of body size, the arytenoid cartilage, dilator muscle and vocal cords show significant differences between the three bioacoustic groups. Furthermore, arytenoid cartilage and dilator muscle volumes predict some temporal parameters and also the dominant frequency of advertisement calls. Our results show important geographic variation in laryngeal morphology, which is in correspondence with acoustic, behavioural and genetic variation in this species.

The issue of food safety and quality control is a top priority for every country. Owing to the intensive use of chemicals and preparations during the cultivation of crops of plant origin, there are cases (25-70%) when in the products sold, the content of nitrates is much higher than the norms. Consumption of such products can provoke deterioration in overall health, as exposure to high doses of nitrates leads to the development of tissue hypoxia in humans and inhibits oxidative phosphorylation. Chronic forms of nitrate poisoning due to oxygen starvation of organs and tissues, which is accompanied by impaired metabolism, reproductive function, suppression of immunity. These research results indicate the urgency of the control of nitrates in plant products consumed by the population of Ukraine. The purpose of the study was to establish the exceedance of the permitted levels of nitrate content in plant products that were tested at the State Research Institute for Laboratory Diagnostics and Veterinary Expertise during 2018-2019. Materials and methods. The analysis of the obtained data was carried out on the basis of the results of studies of nitrate content in samples of plant products, which were tested at the laboratory for determination of veterinary preparations and contaminants of the Research Chemical-Toxicology Department of the State Institute for Scientific and Technological Research during 2018-2019. Studies on the nitrate content were performed by ionometric method according to the current DSTU 4948: 2008 Fruits, vegetables and products of their processing. Methods for determining nitrate content. Results. The analysis of the results of the research conducted during 2018-2019 shows that in all types of studied plant products revealed exceedance of the maximum permissible levels (MPL) of nitrate content. It should be noted that a comparative analysis of the data obtained in 2018-2019 indicates the dynamics of an increase in the number of tested plant products with an excess of MPL of nitrates from 18 to 22%. Excess nitrates in plant products in 2018 were found to be more commonly found in beet, strawberry and carrot samples in 2018, and in 2019 in zucchini, cabbage and cucumbers. Probably, the harvesting of vegetables, from the data of the studied samples, was carried out in the early stages of plant vegetation. It is known that nitrates are most intensely absorbed by plants during the development of stems and leaves, not during the period of full maturation. Probably because of these samples of vegetable products the excess of MPL of nitrates was determined, which indicates that the vegetables are not suitable for consumption, since they can potentially cause toxic effects on the human body.

Este trabajo explora la estrategia que siguió el gobierno mexicano para construir las capacidades tecnológicas que requería el desarrollo industrial del país. Estudiamos el papel central que jugó el Banco de México en este proceso, cuyos directivos supieron aprovechar la coyuntura económica y política que generó la segunda guerra mundial, para atraer al país la experiencia en materia de desarrollo tecnológico que venía acumulándose con gran pujanza en Estados Unidos. A diferencia de lo que suele destacarse del periodo, esta no fue una historia de aislacionismo, sino de cooperación internacional, en la que la visión de algunos mexicanos que ocupaban puestos clave en el gobierno se conjuntó con la de varios ingenieros y científicos norteamericanos y mexicanos para crear una institución clave para el desarrollo tecnológico del país: el Instituto Mexicano de Investigaciones Tecnológicas.

A distributed control strategy is proposed to share unbalanced currents in three-phase three-wire isolated AC Microgrids (MGs). It is based on a novel approach where, rather than analysing the MG as a three-phase system, it is analysed as three single-phase subsystems. The proposal uses a modified single-phase $Q-E$ droop scheme where two additional secondary control actions are introduced per phase. The first control action performs voltage regulation, while the second one achieves the sharing of negative sequence current components between the 3-legs power converters located in the MG. These secondary control actions are calculated online using a consensus-based distributed control scheme to share negative sequence current components, voltage regulation, and regulating the imbalance at the converters' output voltage to meet the IEEE power quality standards. The proposed methodology has the following advantages over other distributed control solutions, such as those based on the symmetrical components or those based on the Conservative Power Theory: (i) it achieves sharing of unbalanced currents, inducing smaller imbalances in the converters' output voltages than those of other methods, and (ii) the sharing of the unbalanced currents is simultaneously realised in both the sequence domain and the a-b-c domain. The latter is difficult to achieve using other solutions, as will be demonstrated in this work. Extensive experimental validation of the proposed distributed approach is provided using a laboratory-scale 3-wire MG.
