Published: December 2022

Unit A of Kurra Chine Formation has been studied in the well Shaikan - 4 (SH-4) at Shaikan Oilfield in Northern Iraqi Kurdistan Region. The available conventional wireline log data and the existed core test values have been used to characterize the reservoir properties of the studied unit and to determine the flow efficiency of the reservoired fluids. The dolomite and anhydrite dominated lithology of the studied unit contains low percentages of shale except the upper most part of the unit in which shale content exceeds 30%. The porosity is less than 5% in most parts of the unit and secondary porosity comprises less than 4% of the total porosity in some horizons. The shale content consists primly of Illite and Chlorite and distributes in a dispersed pattern. Hydrocarbons are exist almost along the studied unit in saturations exceeding 70% at the middle and lower part of the unit. No effective permeable intervals observed at the upper part of the unit, whereas permeable zones of greater than 70mD are observed at the lower part. Three reservoir units distinguished in Kurra Chine A unit based on variations in shale content, porosity, and permeability. The studied unit contains four distinctive types of Hydraulic Flow Units (HFU) of less than 2.0, 20-5.5, 5.5-10, and greater than 10 Flow Zone Indicator (FZI) values. The calculated net to gross pay ratio for the studied Kurra Chine A Unit appeared to be about 28% representing the collective 52m net pay to the 184m gross thickness of the studied A Unit.

Resistance to the downy mildew pathogen Plasmopara halstedii (Farl.) Berlese et de Toni in sunflower is controlled by the resistance gene Pl. The Plarg gene is currently promising in breeding for resistance as it is effective against all known races of the pathogen. This gene is introgressed from the wild species Helianthus argophyllus. Molecular markers and, in particular, simple microsatellite repeats (SSRs) allow to control the transfer and pyramiding of disease resistance genes. However, validation of the molecular marker is needed to prove its reliability. The microsatellite marker ORS 822 was tested to identify the Plarg gene. We conducted the research on a hybrid combination of a susceptible sunflower line of VNIIMK's breeding VK 925 and a resistant line RHA 419, a donor of the Plarg gene. We es-tablished that these lines differ from each other by the allelic state of this locus. Molecular analysis of the F1 generation showed that the microsatellite locus is inherited codominantly. We obtained the F2 generation by self-pollination and made a phytopathological evaluation of resistance to P. halstedii. Split analysis by ph-notype showed that the actually observed segregation corresponded to the theoretically expected 3:1 model for monogenic inheritance of the trait. Based on the obtained data, we determined that the Plarg gene and microsatellite locus ORS 822 are linked with a recombination frequency of 0.26. As a result of this research, we concluded that this marker can be used to select homozygous resistant sunflower plants for resistance to downy mildew in marker-assisted selection (MAS).
Results of agronomic research on sunflower in Crimea
Authors:   Crimea Research Institute of Agriculture, Kostenkova E.V.
Published: December 2022

The research was aimed at developing a scientifically justified cultivation technology for sunflower hybrids of domestic breeding, ensuring their high productivity and seed quality in the arid conditions of the Crimean Peninsula. In the contrasting weather conditions of the research years (2017-2021), the hybrids Signal (1.22 t/ha), Garant, and Sprint (1.18 t/ha) were notable in terms of yield. Hybrids Komandor, Garant, Sprint, and Gorstar (coefficient of ecological plastici-ty bi > 1) were distinguished as demanding to the agronomy level. The hybrid Kometa should be cultivated on an extensive background (coefficient of ecological plasticity bi < 1) to unlock its potential at minimum cost, and it was the most stable in terms of yield (stability index Ϭd2 = 0.48). The most unstable hybrid was Kommandor (stability coefficient Ϭd2 = 2.19). We formed the optimal parameters of the sunflower hybrid model for the conditions of the steppe zone of the peninsula. We established the influence pattern of water reserves in the soil before sowing, HTC and precipitation during the growing season, as well as the natural water availability of the cultivation zone on the sunflower yield depending on the plant density at different sowing dates. The sunflower hybrid Avangard should be sown in the beginning or end of April at a given density of 40-50 thousand plants/ha to guarantee a high yield (1.19-1.32 t/ha). We noted that the seed oil content did not depend on the plant density but decreased if the hybrid was sown late (from 45.2 to 41.6%). Due to the uncertain-ty of water availability during the growing season, it is advisable to sow the sunflower hybrid Fakel in April on two dates – one part in the beginning, and one part at the end of the month with a density of 40 thousand plants at harvesting time (1.35-1.39 t/ha). We noted that the oil content of sunflower seeds decreased at late sowing (from 45.2 to 40.8%) and did not depend on the plant density.

The research was conducted in 2020-2022 to find effective ways of controlling the volunteer plants of imidazolinone-resistant sunflower in oil flax sowings, providing high biological and economic efficiency, crop yield, and seed quality on leached chernozem in natural and climatic conditions of the Western Ciscaucasia. We studied methods of chemical protection of oil flax with tank mixtures of herbicide combinations: anticotyledonous contact herbicide Basagran, WS and systemic herbicide Cleo, WDG, Sekator Turbo, OD, and graminicide Zellek-super, EC. We used established methods for field agronomic experiments with oil crops. Seeds of imidazolinone-resistant sunflower hybrid were evenly sown on the experimental plot to simulate the volunteer plants. The phytotoxicity of herbicides on sunflower plants was evaluated using a 9-point EWRC scale. The tank mixtures Basagran,WS (4 l/ha) + Zellek-super, EC (1.0 l/ha) and Basagran, WS (4 l/ha) + Sekator Turbo, OD (0.1 l/ha) + Zellek-super, EC (1.0 l/ha) do not provide ef-fective control of the volunteer plants and are not recommended for use. The composition Basagran, WS (4 l/ha) + Cleo, WDG (0.12 kg/ha) + Zellek-super, EC (1.0 l/ha) provides destruction of the volunteer plants, contributing to higher yield and oil content of seeds, but it is very expensive and decreases the laboratory germinating ability of flax seeds, so it cannot be used in industrial seed production. A tank mixture of Cleo, WDG (0.12 kg/ha) + Sekator Turbo, OD (0.1 l/ha) + Zellek-super, EC (1.0 l/ha) has lower cost, provides high herbicidal effectiveness against the volunteer plants of imidazolinone-resistant sunflower, contributes to obtaining a high yield, oil content and laboratory germination of oil flax seeds and is recommended for use both in industrial seed production and in the production of commercial seeds.

The article presents the results of research on determining the impact of light pulsed ultraviolet radiation of "Ecosvet-1" device with different intensities (4, 8, 16, and 32 kJ/m2) on laboratory germinating ability of spring rapeseed variety Tavrion and its infestation by pathogenic microorganisms. The experiment was conducted at V.S. Pustovoit All-Russian Research Institute of Oil Crops in 2022. We determined the laboratory germination of seeds of rapeseed according to State Standard 12038-84 in Petri dishes in a humidity chamber, and the infestation by the diseases – according to State Standard 12044-93. Laboratory germination of rapeseed seeds in the control was 63.0%. The cause of the germination decrease was affection by fungi of the genera Alternaria Nees and Fusarium sp. Link, as well as by bacteria of the genera Pseudomonas Migula and Xanthomonas Dowson. As a result of the treatment of rapeseed seeds with a noninvasive polychromatic light pulse, there was an increase in laboratory germination by 6-16 % compared to the control due to a decrease in seed infection. According to the obtained data, the best result in the experiment showed the variant with a specific dose of ultraviolet radiation (SD UV) of 8 kJ/m2. Laboratory germination of seeds in this variant was 79.0%. All seedlings from normally germinated seeds were healthy. The prevalence of Alternaria blight was 2 times lower on non-germinated seeds than on the control, Fusarium blight – 3 times lower, and bacterial blight – 1.5 times lower. The obtained data suggest that this method is promising for the presowing disinfection of rapeseed seeds from pathogenic microflora.

Published: December 2022

As a result of the research on the threshing process of individual soybean plants, it was found that the formation of additional lateral branches on soybean plants significantly complicates their threshing by known combing methods that spare the integrity and viability of breeding and genetically valuable seeds. This leads to a significant slowdown in the threshing speed and reduces its quality. Analysis of previously developed devices for combing plants on the root revealed the inefficiency of their constructive solutions for individual soybean plants, since to comb all the beans from a multibranched plant on known combing devices, it is necessary to divide the plant into its separate branches and separate each from the beans. The research conducted at V.S. Pustovoit All-Russian Research Institute of Oil Crops allowed us to develop a design of a combing device that provides combing of beans from a multibranched soybean plant in one pass with a high coefficient of the combing process.

Published: December 2022

This study aimed to investigate the perceptions of primary school teachers on who would be best to teach English and who should take responsibility for improving the English learning of underachievers in English. For the study, 107 elementary school teachers participated in the survey, and they consist of three groups: English subject specialized teachers (ETs), homeroom teachers (HTs), and homeroom teachers teaching English (HTEs). The results of the study are as follows. First, regarding who should teach English, 64.5% of 107 teachers answered ETs should be in charge of English classes, while only 28% of them suggested that HTs should. Compared to the other two groups, a higher percentage of HTEs favored having homeroom teacher teaching English. Second, regarding the responsibility of teaching English to underachievers, 70.5% of ETs and 86% of HTs answered that ETs should take more responsibility than HTs at a ratio higher than 8:2. In other words, most teachers think that ETs should have a higher percentage of responsibility in improving poor English learning.
Discussions and suggestions are made on what to do in consideration of the findings on teachers’ perception and the ideal situation to help underachievers in English.

Published: December 2022

Optimizing water injection rate distribution in waterflooding operations is a vital reservoir management aspect since water injection capacities may be constrained due to geographic location and facility limitations. Traditionally, numerical grid-based reservoir simulation is used for waterflood performance evaluation and prediction. However, the reservoir simulation approach can be time-consuming and expensive with the vast amount of wells data in mature fields.

Capacitance Resistance Model (CRM) has been widely used recently as a data-driven physics-based model for rapid evaluation in waterflood projects. Even though CRM has a smaller computation load than numerical reservoir simulation, large mature fields containing hundreds of wells still pose a challenge for model calibration and optimization. In this study, we propose an alternative solution to improve CRM application in large-scale waterfloods that is particularly suitable for peripheral injection configuration. Our approach attempts to reduce CRM problem size by employing a clustering algorithm to automatically group producer wells with an irregular peripheral pattern. The selection of well groups considers well position and high throughput well (key well). We validate our solution through an application in a mature peripheral waterflood field case in South Sumatra. Based on the case study, we obtained up to 18.2 times increase in computation speed due to parameter reduction, with excellent history match accuracy.

Published: December 2022

The optimization of material flow systems requires a profound understanding of the underlying processes. Business Process Model and Notation (BPMN) is an established way of creating a process model that allows an interdisciplinary analysis and optimization. Quantitative exploration of systems using discrete-event simulation can help to enrich these insights. For that reason, this paper introduces a combined BPMN simulation approach that connects the advantages of both modeling frameworks. By synthesizing systems from generic modules, a comprehensive yet structured optimization process chain is developed. A case study evaluation based on key metrics for material flow.

Published: December 2022

The growing usage of plastics in their various forms and applications has resulted in an exponential increase and spread of microplastics throughout the environment. We present a review based on a comprehensive analysis of the CAS content collection on the awareness of the underlying detrimental effects of several types of microplastics. The sources of this microplastic pollution are derived from its direct production or the degradation of macroplastics and include items such as personal care products, synthetic textile fibers, and rubber tires. The most frequent polymers observed in microplastic pollution are polyethylene, polystyrene, polypropylene, polyethylene terephthalate, and polyvinyl chloride. These plastics are frequently mixed or combined with chemical additives such as phthalate and polybrominated biphenyls and are prevalent throughout the atmosphere, water, and in food. When these plastic pollutants are ingested or inhaled, adverse health effects are likely to result. This review reports the current scientific literature on microplastics and aims to analyze the current knowledge regarding their toxicology and potential solutions for the management and remediation of this type of plastic pollution.

Home gardens is the reservoir of biodiversity and have played great role in on farm conservation and promotion of species. Biodiversity is a crucial component of agricultural system. Therefore, this study focused on assessment of the factors and structures affecting conservation of agrobiodiversity. The study used the techniques of household survey. The result showed that the home garden occupies only 10-16% of the total land. Size of home garden varied from 0.007 ha to 0.31 ha. The Shannon-Weaver’s index for rural community (H’=2.44) revealed that the rural community harboured higher plant species diversity in home gardens as compared to urban communities. Total 102 species belonging to 25 families have been taxonomically identified and recorded.

Drought is the condition of prolonged paucity in the water supply, whether atmospheric, surface water, or groundwater. This significant abiotic stress is a severe limiting factor of plant growth and rice productivity, adversely affecting the economic rice production globally. Drought stress has a considerable effect on the rice plant’s morphological and physiological traits preventing it from reaching the maximum yield. Morphological alteration in rice includes inhibition of seed germination, reduced tillers, early maturity, reduced biomass while physiological changes involve restricted cell division and elongation, stomatal closure, loss of turgor adjustment, lower photosynthesis, slower growth rate, yield reduction, etc. The stress further brings about a biochemical change by accumulating stress metabolites, increasing Reactive Oxygen Species (ROS) accumulations, increasing antioxidative enzymes and, Abscisic acid (ABA) accumulation. Various mitigation measures are applied to adhere to the effect of drought on rice plants by selecting drought-tolerant cultivars, planting early varieties, sufficient moisture maintenance, conventional breeding, molecular maintenance, and development of varieties with high yielding attributes. Thus, this review aims to assess the complex responses of rice plants to drought in morpho-physiological characters of rice along with its mitigation strategies in adoption to drought stress.

Maize is one of the important cereal crops in sub-Saharan Africa (SSA) and an important staple food for more than 1.2 billion people in (SSA) and Latin America. Inspite of this, a study was conducted to investigate the effect of Neem Extract in the control of fall armyworm (Spodoptera frugiperda) on some maize varieties such as Sammaz 15, Rido 9, Sammaz 34, Kapan 6, Oba 98, and Oba super 6. The experiment was laid down in Randomized Complete Block Design (RCBD) with three replications. Six varieties of maize were evaluated in Minna, Nigeria during 2021 cropping season. Growth and yield parameter were recorded. The data were subjected to analysis of variance. Results revealed that the effect of Neem Extract varied among the six maize varieties in control of fall armyworm. Sammaz 34, Sammaz 15, and Oba 98 were superior in most of growth and yield parameter. These three varieties could be adopted for breeding for high yield and tolerant to fall armyworm in the study area.
La supradiégesis Musical en el Sistema de Combate de los JRPG
Authors: Porta-Pérez Alberto
Published: December 2022

La música interviene en el videojuego mediante su propio lenguaje acompañando al jugador a lo largo de la ludoficción pudiendo ejercer un rol fundamental en el gameplay. En este trabajo en particular nos cuestionamos el papel que juega la música y su narrativa en los JRPG y concretamente en su participación dentro de los sistemas de batalla o combates. Para esta investigación nos acogemos a la ludomusicología entendida como la subdisciplina que estudia la música en los videojuegos y nos apoyamos en un marco metodológico propio de los game studies. Comprobamos que la música, entre otras funciones, puede actuar desde una capa privilegiada, una supradiégesis musical, capaz de acentuar la acción, ubicar al jugador en el espacio o informar de la dificultad del enfrentamiento influyendo tanto en el relato videolúdico como en la actitud del jugador frente a la batalla, en su inmersión y en su afecto. Music intervenes in the video game with its own language, accompanies the player throughout the game and can play a fundamental role in the gameplay. In this particular work we question the role played by music and its narrative in JRPGs, specifically in its participation in battle systems. For this research we use ludomusicology understood as the subdiscipline that studies music in video games and we rely on a methodological framework of game studies. We verified that the music, among other functions, acts from a privileged layer, a musical supradiegesis, capable of accentuating the action, locating the player in the space or informing about the difficulty of the confrontation and influences the videoludic story and the player in his attitude, his immersion and his affection during battle.
The Fictional Incompleteness of Digital Gameworlds
Authors: Van de Mosselaer Nele , Gualeni Stefano
Published: December 2022

This paper presents and analyzes forms of fictional incompleteness that are commonly encountered as part of the experience of playing digital games. While some of these forms are recognized to be compatible with the incompleteness that characterizes non-interactive fictions (such as novels, paintings, and films), some of the ways in which fictional worlds are only partially presented to their users are unique to computer-mediated, interactive fictions. In this regard, this paper specifically focuses on the inevitable incompleteness of in-game affordances, the unique ways in which players experience the boundaries of gameworlds, and how incompleteness in digital games becomes apparent in the encounters with repeated instances of the same game assets
Kindlin2 enables EphB/ephrinB bi-directional signaling to support vascular development

Direct contact between cells expressing either ephrin ligands or Eph receptor tyrosine kinase produces diverse developmental responses. Transmembrane ephrinB ligands play active roles in transducing bi-directional signals downstream of EphB/ephrinB interaction. However, it has not been well understood how ephrinB relays transcellular signals to neighboring cells and what intracellular effectors are involved. Here, we report that kindlin2 can mediate bi-directional ephrinB signaling through binding to a highly conserved NIYY motif in the ephrinB2 cytoplasmic tail. We show this interaction is important for EphB/ephrinB-mediated integrin activation in mammalian cells and for blood vessel morphogenesis during zebrafish development. A mixed two-cell population study revealed that kindlin2 (in ephrinB2-expressing cells) modulates transcellular EphB4 activation by promoting ephrinB2 clustering. This mechanism is also operative for EphB2/ephrinB1, suggesting that kindlin2-mediated regulation is conserved for EphB/ephrinB signaling pathways. Together, these findings show that kindlin2 enables EphB4/ephrinB2 bi-directional signal transmission.

David Kolb’s learning theory called Experiential Learning Theory states that learning is not just listening, but reflecting on what has been learned. That learning process can be carried out well if students can understand the material that has been studied by being directly involved in the proving process. Especially in mathematics. Mathematics is still a subject that is not liked by students. Students assume that mathematics is a rote science and it is difficult for them to solve mathematical problems. Therefore, in this article, it will be explained related to David Kolb’s learning theory an its applicationto mathematics learning in Cartesian coordinates. The research method used in the preparation of this article is a literature study on David Kolb’s learning theory and its application to mathematics learning in cartesian coordinates. Experiential learning is carried out through 4 stages, that is 1) concrete experience (feeling), 2) refelection observation (watching), 3) abstract conceptualization (thinking), and 4) active experimentation (doing). Kolb also explained that there are 4 different learning style, that is 1) diverger, 2) assimilator, 3) converger, and 4) accommodator
