Published: October 2023

Abstract

At present, water rights trading is used by many countries around the world to solve the problems of water resource shortage and uneven spatial and temporal distribution. However, there is no scientific method for setting the term of water rights trading, which is generally determined through negotiation between the trading parties. In order to find a more objective method for determining the term of water rights trading, we constructed a loss–benefit model about the term of water rights trading and solved it based on the principle of comprehensive benefits greater than zero to determine the optimal term of water rights trading. First, we analyzed the benefits and losses brought by water rights trading, then constructed a loss–benefit function with trading term as the independent variable. Second, based on the graphical analysis method, we analyzed the benefits and losses of water rights trading. Finally, the optimal term for water rights trading is determined based on the loss–benefit function and combined with a graphical analysis method. In addition, this study can also help us determine the longest or shortest water rights trading term based on actual situations.

Published: October 2023

The main goal of time series analysis is to explain the main features of the data in a chronological order and in the general case to predict future processes, products, service requirements, etc., using appropriate statistical models. In this paper, time series prediction was performed using a seasonal autoregressive integrated moving average model (SARIMA) in the XLSTAT add-in for Excel environment, as well as two artificial neural network (ANN) models - long short-term memory (LSTM) network and relatively new machine learning technique - extreme learning machines (ELM). The proposed approaches were used for forecasting the volume of packages in the internal postal traffic of Serbia for the period 2014-2020. A comparison of the obtained modeling results with the original data was made and it was shown that the best modelling results were achieved by using ELM.
Med värden i fokus. Om den didaktiska vad-frågan i pragmatiskt informerad undervisning i förskolan.
Authors: Löf Camilla , Vallberg Roth Ann-Christine 
Published: October 2023

Sedan undervisning fick en mer framträdande position i den svenska reviderade läroplanen för förskolan (Lpfö 18) har lärare i såväl förskola som förskollärarutbildning kämpat med att tolka konceptet. När 2011 års skollag trädde i kraft några år tidigare fick förskolans arbete med normer och värden en starkare ställning. Mot bakgrund av detta blir det intressant att studera båda dessa stärkta mandat – undervisning och värden. Med utgångspunkt i erfarenheter från ett didaktiskt och pragmatiskt informerat undervisningsupplägg är syftet med denna artikel att bidra med kunskap om vilka värderingar som kan framträda i undervisning i förskola. Det empiriska material som genererats genom undervisningsupplägget består av totalt 364 dokument, inklusive 64 videoinspelningar. Detta genomfördes på cirka 120 förskolor och/eller förskoleavdelningar i tio svenska kommuner. Analysen har en didaktisk ansats och kan metodologiskt beskrivas som abduktiv analys. Resultatet indikerar att pragmatiskt informerad undervisning om värden kretsar kring sociala värden, såsom demokrati och (barns) delaktighet. I förskolans praktik är undervisningen organiserad som möjligheter till reflektion, samt som ett ”flerdeltagande”. Vidare framträdde spår av flerstämmighet i relation till kunskapsinnehåll som samspelar på flera olika nivåer samtidigt.
ENGLISH ABSTRACT
Focusing values. On the didactic question “what” in pragmatically informed teaching in preschool
In 2018 teaching was enhanced in the Swedish revised curriculum (Lpfö 18). Both in the preschool practice and in teacher preparation, teachers seem to struggle with the concept. When the Swedish Education Act of 2011 entered into force, the work of preschools with norms and values was also accorded a stronger position. In light of this, it becomes interesting to study both of these strengthened mandates – teaching and values. Drawing upon experiences from a didaktik and pragmatically informed teaching approach, the aim of this article is to contribute with knowledge of what kind of values that can appear in the teaching at the participating preschools. The material underlying the teaching approach consists of a total of 364 documents, including 64 video recordings. This was carried out in about 120 preschools and/or preschool departments in ten Swedish municipalities. The analysis takes a didactic approach and can be methodologically described as abductive analysis. The results indicate that pragmatically informed teaching of values revolves around social values, such as democracy and (children’s) participation; in the preschool practice, the teaching is organized as opportunities for reflection and ”multiparticipation”. Additional traces of multivocality emerged from integrative knowledge content moving within and between various value levels.

Published: October 2023

A COVID-19 resultou em milhares de óbitos e até o presente momento assola diversos pacientes com as suas implicações. Uma das consequências da doença foi o isolamento social, realizado por quase todos os países, o que configurou a alteração de diversos padrões de convivência e principalmente de exposição a outros agentes não patogênicos e patogênicos essenciais para o desenvolvimento da microbiota. Com isso, o seguinte projeto tem como objetivo a descrição dos impactos da pandemia da COVID-19 na microbiota intestinal de lactentes do período pandêmico e as consequências geradas no sistema imunológico imaturo, prejudicando seu desenvolvimento e maturação. A metodologia consiste na análise e seleção de artigos científicos publicados nos últimos 10 anos com auxílio de Descritores em Ciências da Saúde (DeCS) específicos nas línguas inglesa e portuguesa para o tema da pesquisa, sendo a combinação dos descritores feita por meio de operadores booleanos. Conclui-se que a composição da microbiota intestinal é iniciada intraútero e influenciada pela via de parto, contato pele a pele após o nascimento e pela presença da amamentação materna. A modificação das práticas durante a pandemia da COVID-19, pode alterar a microbiologia neonatal, assim como impactar na maturação do sistema imunológico do lactente, predispondo futuramente à doenças gastrointestinais, metabólicas e atópicas, como asma.
Mysteries of the Ethnic Identification of Nelyud Clan and Gantimir
Authors: Zuev A. S. 
Published: October 2023

Purpose. This article, based on the analysis of authentic documentary and narrative sources, examines the variants of ethnic identification of Nelyuds, who lived in the south of Eastern Transbaikalia, and their leader Gantimur, who played a significant role in Russian-Manchu relations and in strengthening Russian power in this region in the second half of the 17th century.Results. The outcomes of the research demonstrate that 1) hypotheses of the ethnic identification of Nelyud clan and Gantimur existing in the historical and ethnographic literature are the result of an uncritical interpretation by researchers of the surviving information; 2) the available information does not allow us to accurately determine the ethnicity of Nelyuds and Gantimur during their initial contacts with Russians; 3) only in the last third of the 17th century Russians began to unambiguously identify Nelyuds, Gantimur and his descendants as the Tungus of the Dulikagir clan.Conclusion. It is established that in the middle of the 17th century Russians, who came to Transbaikalia, consider the “Nelyud clan” mainly as a special ethno-territorial union, different from other peoples of this region – the Tungus, Daurs, Mongols and others. Only from the second half of the 1660s Nelyuds, Gantimur and his closest relatives are defined in Russian documents and descriptions as Tungus.
Cult Complex in Zanskar: Analysis, Interpretation

Purpose. The study investigates a Buddhist image on a standalone stone and an offering contained in a clay vessel. The cult complex is located near Zangla, not far from the Changut Choeling female monastery, in the north of Zanskar (Ladakh, India).Results. The image depicts the bodhisattva Avalokiteśvara, the patron deity of Tibet. The clay vessel (73 mm in height) found near the stone contains a square iron plate (~25x25 mm) with traces of insets, one of turquois; a transparent crystal bead; and two perforated bones. An examination of the vessel contents revealed that it originally contained a piece of meat or some blood. Based on a traceological analysis of the bone items, they appear to have been worn on a cord. All the items in the vessel are of special significance in the Buddhist culture as well as folk religion of Tibet. They could have served as offerings to Avalokiteśvara as well as local patron deities – btsan and lha, who were believed to live in that stone. After all, Buddhism in Tibet became part of the folk religion. The tradition of making offerings in a vessel placed at the foot of a stone with a divine image has parallels in the culture of Central Asian Turks. Excavations of Turkic mortuaries have revealed silver, as well as ceramic, vessels at the foot of heroic figures. Researchers believe that they were used for sacrificial offerings and for drinks in funeral rituals. Like in Zanskar, such vessels were left on the surface, and over a thousand years must have passed before they became fully covered with earth so that they would later be found during excavations.Conclusion. Offerings in vessels placed at the foot of stone statues of deities and ancestors, as well as stones accommodating local patron spirits, appear to have been common among the peoples of Central Asia in the Middle Ages.

Published: October 2023

Objetivo: Realizar a revisão bibliográfica dos principais fatores de risco e das estratégias para profilaxia e manejo da neutropenia febril (NF) induzida por quimioterapia. Revisão bibliográfica: A NF induzida por quimioterapia é uma complicação grave derivada do tratamento antineoplásico com quimioterápico mielossupressor, estando associada a altas taxas de mortalidade e morbidade. Os fatores de risco para NF podem estar relacionados ao paciente, a doença e ao regime de quimioterapia. Diretrizes internacionais recomendam a utilização de algoritmos para estratificar os pacientes quanto ao risco de complicações graves decorrentes da NF. A profilaxia e o manejo da NF com fator estimulador de colônia de granulócitos (G-CSF), reduz a incidência, duração, e taxa de mortalidade associada a NF. Filgrastim e pegfilgrastim são os G-CSF mais utilizados na prática clínica, porém, apresentam reações adversas como dor óssea e muscular, sendo necessária uma avaliação cuidadosa do risco-benefício para o paciente. A profilaxia com G-CSF é recomendada principalmente para pacientes submetidos a quimioterápicos de alto risco para NF, ou de risco intermediário quando o paciente apresenta características de alto-risco. Considerações finais: A adequada profilaxia e manejo da NF acarreta aumento da qualidade da assistência ao paciente oncológico e redução dos custos para os sistemas de saúde.

Description of the subject. Novel sensitizer environmentally friendly natural pigments with suitable colors for dye-sensitive solar cells (DSSCs) are required. Here, melanized structures to obtain pigments formed by Aspergillus niger, Sclerotium cepivorum, and Albifimbria verrucaria, were used. Objectives. The goal of this study was to build DSSC solar cells to study the operation of these extracted melanins from these fungi. Method. Melanin extraction from fungal structures was carried out using KOH-HCl and NaOH-HCl and applied in the DSSC. Results. The melanin from A. verrucaria had the best fill factor (FF) (0.718), followed by that from S. cepivorum and A. niger (0.708 and 0.525). Sclerotium cepivorum melanin had the highest effectiveness (0.320%), followed by A. verrucaria (0.160%) and A. niger (0.149%). Conclusions. The I-V and V-P curves in the evaluation tests showed that fungal melanin behaved as a semiconductor; as a result, the development of DSSC-type solar cell devices employing extracts from different sources of fungal melanin appears promising.

Modelling of the stress and strain state of a geoenvironment in a gravitational field, taking into account data on its structure, is part of comprehensive research in geodynamics. The gravitational field caused by the density inhomogeneity of the Earth’s tectonosphere is one of the internal sources of generating tectonic stresses. A unified 3D-model is proposed to study possible dislocations of inhomogeneous layers of the tectonosphere. The kinematics is determined by the Cauchy – Green strain tensor, the stress state is described by the unsymmetric Piola – Kirchhoff stress tensor. All parameters are obtained in the analytical form for the Murnaghan state equation. At the stage of numerical experiment, it is possible to embed an inhomogeneous density and distributions for other properties of the geoenvironment. The density model is used according to the coordinate grid: depth – latitude – longitude. The density values are determined based on deep sounding and gravimetry data. Numerical reconstruction of inhomogeneous fields of displacement and rotation, of strain and stress intensity of the Earth’s crust for the data of the Central Kuriles profile density model is performed. The relief of the profile surface is determined by the stress and strain state of the deep structures. The potential possibility of movement in the direction from the oceanic plate to the continental one and the transition of geoenvironment to a plastic state are modelled. The allocation, the detail of the layered and block structure in the hypocenter zones of the Simushir earthquakes, and the concentration of strain and stress fields are consistent with the density differentiation of the Earth’s crust.

Рассмотрены два способа вычисления безусловного максимума распознающего функционала для допускового множества решений интервальных систем линейных алгебраических уравнений. Их объединяет идея сведения исходной задачи максимизации к решению одной или нескольких задач линейного программирования, построенных по данной интервальной системе. Представлена теоретическая основа предлагаемых методов, обсуждаются вопросы программной реализации и вычислительных экспериментов с модельными задачами.
The article considers the solution of interval systems of linear algebraic equations (ISLAE) and presents two simple, fast and reliable ways to find the unconstrained maximum of the recognizing functional of the tolerance set of solutions. The recognizing functional is a special function that, using the sign and magnitude of its values, makes it possible to judge whether a point belongs to the tolerable solution set and gives a measure of “tolerable compatibility” of the interval system of equations at the point. The technique based on the use of the recognizing functional is one of the powerful tools for studying interval systems of equations and their tolerable solution sets. The paper presents two methods for computing the maximum of the recognizing functional, united by the general idea of reducing the original maximization problem to solving one or more special linear programming problems built on a given interval system. The theoretical basis of the proposed methods is presented. The issues of software implementation are discussed, as well as computational experiments with model problems. The reduction is based on the Rohn theorem on the characterization of points of the tolerable solution sets for ISLAE, which allows us to representing it as solutions to a system of linear inequalities. This opens up the possibility of using linear programming methods for unconstrained maximization of the recognition functional and for studying whether the tolerable solution set is empty or notnempy. The methods proposed in this article naturally complement the currently existing algorithms for computing the maximum of the recognizing functional, which use numerical methods of non smooth optimization. Our new methods are both technologically advanced and easy to implement, since they allow us to utilize developed theory and ready-made software products for solving linear programming problems.

Published: October 2023

Padi (Oryza sativa L.) merupakan salah satu komoditas tanaman pangan yang strategis dan cukup penting bagi penduduk Indonesia, karena sebagian besar penduduk Indonesia mengkonsumsi beras sebagai bahan makanan utama. Kebutuhan beras seiring waktu terus meningkat sehingga dibutuhkan upaya peningkatan produksi. Satu diantara upaya yang bisa dilakukan adalah dengan optimalisasi sumberdaya lahan yang ada dengan penggunaan varietas unggul. Berbagai varietas yang telah dikeluarkan tentu memiliki kemampuan adaptasi untuk tumbuh dan berproduksi yang berbeda terutama pada lahan non irigasi seperti lahan sawah tadah hujan. Berbagai kendala seperti ketersdiaan hara yang rendah, tingkat keasaman yang cenderung tinggi serta kondisi pengairan yang hanya berasal dari curah hujan bisa menyebabkan tanaman berproduksi tidak sesuai dengan deskripsinya. Penelitian ini bertujuan untuk mendapatkan varietas yang memberikan pertumbuhan dan hasil padi terbaik pada lahan sawah tadah hujan. Penelitian dimulai pada bulan Maret hingga Juli 2022 di Desa Rasau Jaya. Penelitian menggunakan rancangan acak kelompok (RAK) satu faktor yaitu varietas yang diulang sebanyak 3 kali. Adapun taraf perlakuan varietas tersebut yaitu: v1= Inpari 22, v2 = Inpari 24, v3 = Inpari 30, = v4 Inpari 32, v5 = Cilosari, v6 = Jeliteng, v7 = varietas Baromah, v8 = varietas Sulutan. Variabel yang diamati terdiri dari tinggi tanaman dan jumlah anakan maksimum umur 4, 6, 8, dan 10 MST, umur berbunga, jumlah anakan produktif, berat 1.000 biji, panjang malai, jumlah bulir per malai, dan kepadatan malai. Hasil penelitian menunjukan bahwa perlakuan varietas berpengaruh terhadap variabel tinggi tanaman, umur berbunga, berat 1.000 biji, panjang malai, jumlah bulir per malai, kepadatan malai dan berat gabah kering giling per petak, namun tidak berpengaruh tehadap variabel jumlah anakan dan jumlah anakan produktif tanaman.
