Foreign Policy Tools for Water Management in Central Asia
Authors: Akmatalieva A. M.
Published: November 2021

This article is devoted to the issue of ineffective and irrational water management in Central Asia. Water management has gained transboundary character, states are divided by their upstream and downstream status and water is perceived as unlimited natural resource which requires new approaches. Author proposes foreign policy tools for water management as constant political dialogue, establishment of permanent body on water management and initiation of projects within China’s Belt and Road imitative, US’s Greater Central Asia and Russia’s Greater Eurasia platform. The vital importance of water as natural resource for life and human development is unquestionable and needs special attention in the context of the climate change and growing population of the Central Asian region. Asian Development Bank has provided three recommendations to Central Asian governments in facing climate change as expanding the supply of water available in the future; increasing the productivity of water; and reducing future demand for water. With predictions of the UN Population Prospects by 2050 Central Asia will have about 100 million inhabitants which undoubtedly will also increase the need for water resources. Taking into acount such factors as climate change and growing population the need for water resources will become only vital in the neearest future and demand for effective and rational water management must be already on the regional agenda.

Integrated Teaching Competency Framework for General Education Program: Suggestions and Recommendations for Natural Science Teachers
Authors: Thi Thu Hoai Vu
Published: November 2021

This article investigated the general structure of teaching competencies and integrated teaching competencies of natural science teachers in high school education, the actual situation of integrated teaching in Vietnam and some other countries in the world, and the designing of assessment templates to recognize difficulties of natural science teachers in integrated teaching. It is shown that natural science teachers are facing various challenges in integrated teaching: a lack of professional knowledge and skills in building integrated topics and teaching with this approach, problems in putting integrated teaching techniques into practice. On this foundation, the article presents a procedure for building an integrated teaching competency framework for natural science teachers, then proposes such a framework. This framework consists of 4 competencies and ten criteria with detailed indicators. Natural science teachers can use this framework to develop tools (checklists, rating scales, or questionnaires) to assess their integrated teaching quality and their “colleagues”, henceforth fostering their competencies as required by the General Education Program.

In 2017–2020, on leached black soils in the central climatic zone of the Krasnodar region we studied the patterns of amount of a fraction of certified seeds (amount of physically clean seeds from a sieve with holes of size 2.5 x 20 mm) of the early maturing inbreds – the maternal forms of sunflower hybrids VK 101, VK 678, VK 905, VA 760 and ED 765 bred at the V.S. Pustovoit All-Russian Research Institute of Oil Crops depending on the plant density of 40, 50, 60 and 70 thousand plants/ha. We established the negative dependence of the amount of a fraction of certified seeds on the plant density. On average for 2017–2020, the maximum yield of such seeds was obtained when growing the studied maternal lines with plant density of 40 thousand plants/ha: 95 % in VK 905, 88 % in VK 678, and 76–79 % in VA 760, VK 101, and ED 765. With the increasing plat population from 40 to 70 thousand plants/ha, after each 10 thousand plants/ha on average, the amount of a fraction of certified seeds decreased by 1.9 % in VK 905, by 4.9–5.9 in VK 101, VK 678, VA 760, and by 5.9 % in ED 765; the number of a fraction of certified seeds per head decreased by 37 in VK 95 to 125 pieces in VK 101. The highest weight yield and number of a fraction of certified seeds per 1.0 m2 of sowing area of the maternal lines was obtained when growing VK 101 with a plant density of 50 thousand plants/ha, VK 678, VA 760, and ED 765 – 60 thousand plants/ha, VK 905 – 70 thousand plants/ha. We established the negative dependence of thousand-seed weight on the plant density; as the density increased by 10 thousand plants/ha, 1000-seed weight decreased by 1.4 g in VK 760, by 2.2 g in VK 101, by 3.1–3.2 in ED 765 and VK 678, and by 3.5 g in VK 905.

Broomrape is an obligate parasite and one of the most significant biotic factors reducing sunflower yield. The main means of controlling broomrape is breeding for sunflower resistance to it. New strategies are required to develop parasite resistant breeding germplasm, such as a stacking of key genes or a combination of qualitative and quantitative resistance mechanisms. In this regard, it is necessary to keep searching for new sources of resistance and to combine existing genes in case they are not identical. Thus, it is necessary to determine whether the genes of resistance to race G of broomrape are identical in the sunflower lines bred at the V.S. Pustovoit All-Russian Research Institute of Oil Crops. The research material was the previously developed sunflower lines RG, RGP1, RGP2, RGВ, RGL1, RGL2, and RGM – donors of resistance to race G of broomrape. The F1 hybrids from pair crossbreeding of these lines were obtained in a greenhouse. The F2 hybrids were obtained in the field by self-pollination of F1 hybrid plants. Plants were tested in a greenhouse for resistance and susceptibility to broomrape using the method of early diagnosis. Mathematical processing was performed by using the χ 2 -test. 13 combinations of crossbreeding were received to complete the test for allelism. In each F1 combination 11–33 plants were evaluated for resistance to race G of broomrape. Among the tested combinations, there was no one resistant to broomrape. Despite the differences in the number of affected plants, the affection degree was small in all hybrid combinations – from 1.0 to 1.8. All F2 hybrid combinations were also affected by broomrape. For eight combinations of F2, two phenotypic classes were found. There was no segregation in three combinations. The number of plants of two combinations was too small to perform χ 2 -test. In general, the χ 2 values were higher than the acceptable ones with a probability of 0.05, which indicates that the genes of resistance to race G of broomrape in these lines are identical.

In the Western Ciscaucasia, frequent droughts lead to a decrease in the yield of Echinacea purpurea L., which is a base for immunostimulating preparations. It is possible to mitigate the effect of sharp fluctuations in weather conditions by using growth regulators and microfertilizers, the exogenous application of which allows mobilizing the potential capabilities of the plant organism aimed at increasing its bioproductivity. The purpose of the research was to study the effect of foliar application the growth regulator Zircon and silicon-containing microfertilizer Siliplant on the yield of Echinacea biomass depending on the weather conditions. The weather conditions during the research years differed. Thus, in 2011– 2014, the average daily air temperatures and the amount of precipitation from May to July were almost at the level of the average annual values. And starting from 2015 there has been a significant increase in temperatures and a decrease in moisture availability. Foliar treatment of Echinacea purpurea with Zircon and Siliplant under drought ensured an increase in the biomass yield by 15–20% compared to the control, under stable weather conditions – by 11–18%. Their combined application increased the yield of the green weight by 24–31%, under stable weather conditions – by 18–24%. The high efficiency of the preparations was manifested in the growth of the root system under drought conditions, where the increase in yield was 40–43% at their combined application. The content of hydroxycinnamic acids in the raw material increased by 4–6% regardless of weather conditions and by 9– 10% in the variant Siliplant + Zircon application. Losses of biomass yield under hydrothermal stress amounted to 1–10%, of roots – 4–5%, while in the control the values were 15–25 and 18%, respectively. The biggest preservation of the yield was noted in the Siliplant + Zircon variant, where there was even a small increase in biomass yield – by 4–9%, in roots – by 4%.

Under global warming of the last decade, there is observed an intensive spread of rust in sunflower fields in the Russian Federation, due to the emergence of new races of the pathogen. It is obvious that there is a need to breed sunflower for resistance to new pathotypes and to correct the technique of artificial inoculation of plants in relation to them. Sunflower breeding for rust resistance has not been carried out since the 1980s. Objective of the study is determining the optimal temperature range for artificial inoculation of sunflower leaves with modern pathotypes (300 and 700) of the rust pathogen. The work was performed in the laboratory of immunity of the V.S. Pustovoit All-Russian Research Institute of Oil Crops in 2020–2021 using monopustular isolates of Puccinia helianthi with virulence codes 300 and 700. The germination of mature urediniospores, the duration of the incubation period and the degree of damage to sunflower plants at different temperatures were studied. The incubation period of pathotypes 300 and 700 of P. helianthi at a temperature of 26–28 °C is reduced by 2–3 days, which is essential both for the rapid identification of the racial identity of the pathogen isolates and for shortening the period for assessing sunflower genotypes when breeding for immunity. To speed up this work, the infection of sunflower plants should be carried out in the phase of the first pair of true leaves at a temperature of 22 °C, followed by a 24-hour stay in a humid chamber at 20 °C and a further increase in the growing temperature to 26–28 °C.

Cultivation of oil crops of Brassicaceae family is an important part of agricultural production in many countries. Currently, interest to Brassicaceae crops is caused with their high productivity, diverse fatty-acid composition of oil of the modern cultivars, and a possibility to use them by various ways. Vegetable oils produced from Brassicaceae crops are, on the one hand, a basis of a rational human nutrition, on the other hand, this is a necessary raw material for the different industries. A balance between general chemical and amino acid compositions of protein allows using it in production of compound animal feeds and foods based on vegetable protein, having high nutritional value and useful technological characteristics (oil, protein, and essential amino acids contents). This paper presents a comparative description and principal features of the general chemical and amino acid composition of some oil crops of the Brassicaceae family. Analysis of the Russian and foreign literary sources proves the importance of further development and studying in this direction with the aim of breeding new cultivars with desired properties and providing domestic food industry with quality and safe products.
Contralateral metastatic cerebellopontine angle glioblastoma: A rare manifestation
Authors: Bajwa Mohammad Hamza , Ul Islam Mohammad Yousuf , Bukhari Syed Sarmad , Khan Ahsan Ali , Ahmad Zubair , Enam Syed Ather
Published: November 2021

Background:

Glioblastoma is the most common glioma presenting within adults with an incidence of 10 per 100,000 people globally. These are mostly supratentorial tumors with rare cases of extra-axial spread. Even rarer is the presentation of glioblastoma within the cerebellopontine angle (CPA). Here, we present a case of a previously resected and irradiated glioblastoma metastasizing from the right temporal lobe region to the contralateral CPA.

Case Description:

A 24-year-old female who previously underwent surgery and concurrent chemoradiotherapy for a right temporal glioblastoma in August 2020, presented to us 6 months later with headaches, vomiting, and dizziness for the past 6 days. She had left-sided dysmetria on examination. MRI of the brain showed an extra-axial, heterogeneously enhancing lesion within the left CPA. The patient subsequently underwent a left retrosigmoid craniotomy and maximum safe resection of the lesion. Histopathology reported the lesion as a glioblastoma.

Conclusion:

Glioblastoma within the CPA is rarely reported within the literature. To date, our case is the first instance of an extra-axial contralateral metastasis of glioblastoma.

Published: November 2021

Background:

Ossifying fibromyxoid tumor (OFMT) is a rare musculoskeletal soft-tissue neoplasm of uncertain histogenesis most frequently occurring in the lower extremities. Conventionally, considered benign, these tumors are often managed by surgical resection followed by surveillance. However, malignant OFMTs with an increased propensity for local recurrence and distant metastasis have been recently identified, and the role of adjuvant therapy in these more aggressive cases is unclear.

Case Description:

We present, to the best of our knowledge, the first reported case of a primary, malignant, and intracranial OFMT. A 29-year-old female presented with recurrent headaches secondary to a large mass in her right frontal lobe. She underwent gross total resection of the brain mass with final pathology consistent with malignant OFMT demonstrating high-risk features including increased cellularity, grade, and mitotic activity. Due to these high-risk features, she received postoperative fractionated stereotactic radiation therapy (FSRT) to the resection cavity, and to the best of our knowledge, she represents the only known patient with OFMT to be treated with adjuvant FSRT. She tolerated the adjuvant treatment well with no acute or late toxicities and remains disease-free over 5 ½ years after resection.

Conclusion:

Adjuvant FSRT appears to be a safe and efficacious approach for managing this rare intracranial disease presentation. We review this patient’s clinical course in the context of the literature to demonstrate the difficulties associated with accurate diagnosis of this rare tumor and the controversial role of adjuvant therapy in preventing disease recurrence in this patient population.
Une fidélité de Foucault à Nietzsche : le langage comme fil conducteur généalogique
Authors: Salanskis Emmanuel
Published: December 2021

Cet article vise à montrer que Foucault a pris au sérieux, dans ses propres généalogies, un aspect méthodologique crucial de la Généalogie de la morale de Nietzsche, qui est le fait que la relative stabilité des formes linguistiques par rapport aux mutations du sens peut servir de fil conducteur au généalogiste dans sa recherche de traces du devenir. Pour ouvrir ce champ d’investigation, il faut commencer par se libérer du préjugé du mot, c’est à dire de l’illusion qu’un universel invariant serait attaché à chaque vocable (par exemple « le bien » chez Nietzsche ou « l’État » chez Foucault). Si les mots n’ont pas de signification idéale qui les arracherait en droit à l’histoire, mais sont, au contraire, un « pouvoir dont on cherche à s’emparer », alors l’histoire des mots est significative en elle même, ou mieux : elle est, à bien des égards, l’histoire même que nous devons raconter.

Published: December 2021

The article is devoted to the problem of detecting low contrast small-sized objects in two-color images with a powerful spatially non-stationary background. An increase of the detecting reliability is achieved through a combination of three factors: attenuation of the background based on the construction of its locally stationary model; improving the estimation of model parameters by excluding statistically significant outliers from the initial data; joint processing of two-color images with a weakened background component. A method of constructing a linear boundary for detecting a useful signal in a two-dimensional space is proposed. The performance characteristics of a two-channel detector of small-sized objects are presented.

Superimposed Quantum Dots: Emerging Optoelectronics
Authors:   Photonics and Nanocrystal Research Lab (PNRL), Faculty of Electrical and Computer Engineering, University of Tabriz, Tabriz, Iran, A Rostami
Published: November 2021

As everybody knows that electron, phonon, and photon transport in solids (crystals) depends on lattice physical properties. Manipulation of propagation properties needs to manipulate crystal parameters such as lattice constant, atoms in the lattice, etc. There are a limited number of crystalline structures in nature to manipulate charge, phonon, and photon transfer in electronics, acoustics, and photonics. The basic problem is how one can make single crystals with desired charge, phonon, and photon transfer performance? Also, how one can manipulate the mechanical, optical, and electrical performance of a device? It seems that nanotechnology and especially nanoparticles and superimposed nanocrystals can help to solve this problem. In this short letter, the superposition of Quantum Dots as a solution to enhance the capability of device designers in this regard is presented, discussed, and demonstrated by simple numerical simulation. If we use the superimposition of QDs, we can realize multi wavelength lasers in a single cavity [1,2]. The ultra-broadband semiconductor optical amplifiers can be implemented by this idea [3]. Multi wavelength photodetector with multi-electrical output is another most important application that can be realized using this idea [4]. High-efficiency solar concentrator based on superimposed QDs is introduced in [5]. Other interesting applications can be realized using the proposed idea too. All these advantages are related to optical and electrical properties dependency on the size of nanocrystals [6]. So, it is possible to make different crystals using the superimposition of well-known crystals. To demonstrate that, first, by choosing different crystals, and using the superposition of those, it is shown that the obtained structure is similar to a new crystal with a lattice constant that depends on initial superimposed crystal lattice constants as well as a geometrical combination of those. In the second part, we show that using colloidal QDs, it is so easy to combine different QDs with different sizes in a unique solution and a superimposed QDs with the desired density of each QDs will be available.

Introduction: Proximal femur morphometry is important in the stability of the hip joint, the design of implants for hip replacement and forensic identification of unknown human remains. This study aimed at determining the proximal femur morphometry and factors associated with their variation. Materials and Methods: This was a cross-sectional study of the proximal end of 333 dry human femora from persons aged 20 to 75 years from the East African population. All the femora were observed macroscopically for the presence of the third trochanter, and the age, sex and nationality documented. The femoral head and neck circumferences were measured using a tape measure and the neck-shaft angle and the angle of anteversion measured using a goniometer. Data were entered in an Excel sheet and exported to STATA 14 for analysis. Univariate, bivariate and multivariable analyses were performed. A p-value of less than 0.05 was considered statistically significant. Results: Of the 333 dry femora, 7.21% (24/333) had a third trochanter. The mean femoral head circumference was 134.91 ± 8.91 mm, the mean neckshaft angle was 118 ± 6 degrees, the mean angle of anteversion was 17 ± 4 degrees, the mean femoral neck circumference was 91.71 ± 7.40 mm. Statistical significance was achieved between each of the proximal femur measurements and: sex, nationality and third trochanter status. Conclusion: The morphometry of the proximal femur varies with age, sex and nationality. These variations are pertinent in the design of tailored proximal femur implants, assessing the risk of fractures, forensic practice and regional comparisons.
Microbial fermentation of polyethylene terephthalate (PET) plastic waste for the production of chemicals and electricity
Authors: Kalathil Shafeer , Miller Melanie , reisner Erwin
Published: November 2021

Ideonella sakaiensis (I. sakaiensis) can grow on polyethylene terephthalate (PET) as the sole carbon and energy source. Previous work has shown that conversion of the hydrolysis products terephthalic acid (TPA) and ethylene glycol (EG) under aerobic conditions released carbon dioxide and water while yielding adenosine triphosphate (ATP) through oxidative phosphorylation. This study demonstrates that under anaerobic conditions I. sakaiensis ferments PET to the feedstock chemicals acetate and ethanol while co-producing ATP by substrate-level phosphorylation. In addition to PET, maltose, EG, and ethanol can also serve as fermenting substrates. Co-culturing of I. sakaiensis with electrogenic Geobacter sulfurreducens produced electricity from PET or EG. This newly identified plastic fermentation process by I. sakaiensis provides a novel biosynthetic route to produce high-value chemicals and electricity from plastic waste streams.
Coadsorption of NRR and HER intermediates determines the performance of Ru-N4 towards electrocatalytic N2 reduction
Authors: Wu Tongwei , Melander Marko , Honkala Karoliina
Published: November 2021

Efficiency of the electrochemical N2 reduction reaction (NRR) to ammonia is seriously limited by the competing hydrogen evolution reaction (HER) but our current atomic-scale insight on the factors controlling HER/NRR competition are unknown. Herein we unveil the elementary mechanism, thermodynamics, and kinetics determining the HER/NRR selectivity on the state-of-the-art NRR electrocatalyst, Ru-N4 using constant potential density functional theory calculations (DFT). The calculations show that NRR and HER intermediates coadsorb on the catalyst where HER is greatly suppressed by the NRR intermediates. The first reaction step leading to either *NNH or *H determines the selectivity towards NRR or HER. Our results also demonstrate that an explicitly potential-dependent treatment of reaction kinetics is needed to understand NRR selectivity. We provide crucial insight into the complex NRR/HER competition and the role of non-innocent adsorbates, show the necessity of constant potential DFT calculations, and suggest that interfacial proton donors will improve NRR selectivity.
Pattern Recognition of microRNA Expression in Body Fluids using Nanopore Decoding at Sub-femtomolar Concentration
Authors: Takeuchi Nanami , Hiratani Moe , Kawano Ryuji
Published: December 2021

This paper describes nanopore decoding for microRNA (miRNA) expression patterns using DNA computing technology. miRNAs have shown promise as markers for cancer diagnosis due to their cancer type-specificity, and therefore simple strategies for miRNA-pattern recognition are required. We propose a system for pattern recognition of five types of miRNAs overexpressed in bile duct cancer (BDC). The information of miRNAs from BDC is encoded in diagnostic DNAs (dgDNAs) and decoded electrically by nanopore measurement. With this system, we succeeded in distinguishing miRNA expression patterns in the plasma of BDC patients using a label-free method and in real-time. Moreover, our dgDNA-miRNAs complexes can be captured by the nanopore at ultralow concentration, such as 0.1 fM. Such nanopore decoding with dgDNAs could be applied as a simple and early diagnostic tool for cancer in the future.

Exploration of the Role-Playing Model in Primary School Class Activities Under the Background of “Class Activity Month”
Authors: Yu Siliang
Published: November 2021

Education in the new era advocates taking students as the main body and improving students’ core literacy on this basis. Subjectivity has also become one of the keys to quality education. Primary school is not only the initial stage of life, but also the key period to develop students’ subjectivity. At present, there are many problems in class activities, such as the weak concept of taking students as the main body, the lack of subject consciousness among students, the flawed construction system of class activities, the unreasonable evaluation system of class activities, and so on. By establishing the role-playing model under the background of “class activity month,” students can play different roles in class activities and participate in various links, such as theme selection, scheme design, organization, implementation, summary, and evaluation of class activities. Through this process, it does not only improve the quality of class activities, but also cultivate students’ subject consciousness and ability in a certain subject, thus highlighting their subject status in class activities.

The article presents data on the effect of complex chelating agents Chelaton Extra and Chelate Zn on the oilseed flax variety Severny when grown at the field station of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. The study found that the agent Chelaton Extra increased the fiber yield better, and the agent Zn Chelate increased the seed yield by 0.7–1 c/ha and 2.4–2.5 c/ha, respectively. The agent Chelate Zn, relative to Chelaton Extra, increased proteins in seeds by 2.9–4%, lipids by 3.6–4.2%. The use of complex chelating agents increased the oil yield and the amount of unsaturated fatty acids. The essential α-linolenic (Omega 3) acid increased in the oil of the variant with Zn Chelate up to 62.2% relative to the control (55.5%). The microstructure of the shell of oil flax seeds in all variants of the experiments was smooth, without disturbances and damages. The seed nucleus has a distinct porous structure; no differences were found in the variants. Chelate Zn more affected the seed productivity and nutritional value of flaxseeds and flaxseed oil, and Helaton Extra more affected fiber yield. The authors found that the Zn Chelate agent influenced seeds’ chemical composition, promoting an increase in potassium, calcium, magnesium, sulfur, and phosphor by 1.5–5%.
