Rethinking the Purposes of A. I. Guchkov's Trip to Emperor Nicholas II in Pskov in the Days of the February Revolution of 1917
Authors:   Nizhny Novgorod State University, Nizhny Novgorod, Russian Federation, Knyazev Mark A.
Published: April 2023

The question the role of Alexander Ivanovich Guchkov, the leader of the Octobrists, in the events of the eve of and during the monarchy overthrow in February 1917 remains relevant in the modern historiography of the Great Russian Revolution. Most researchers come to the conclusion that Guchkov was induced to participate in the revolutionary events by his desire to oust Nicholas II from power in order to deliver the throne to his heir, Alexei, under the regency of his brother Michael Aleksandrovich. A. I. Guchkov’s trip to Pskov on March 2, 1917, which he undertook intending to persuade the emperor to abdicate, is predominantly considered as practical realization of this plan of the “great master of the revolution.” However, the author has discovered a certain document drafted in the days of the February Revolution in the State Archive of the Russian Federation (specifically, in the fond 97 “Office of the Palace Commandant of the Ministry of the Imperial Court”, file captioned “Correspondence and telegrams of the last days of Nicholas II's reign”). This document, which has been introduced to the scholarly discourse for the first time, can significantly clarify the historiographic picture. The document is a typescript containing a list of presumptive members of the Cabinet of Ministers to be headed by the “Prime Minister” A. I. Guchkov. The source analysis permits to conclude that the document was created by A.I. Guchkov himself or by someone quite close to him in the period from February 28 to March 2, 1917. This text contains a request for Nicholas II to appoint the oppositionist to the high governmental post. By examining the second part of the document, we can deduce that this request was in fact an ultimatum, as it contains information about the arrest of prominent state dignitaries and ministers and about 18 regiments (up to 75,000 people) joining the revolution. Thus, Guchkov went to Pskov not only to ensure the emperor’s abdication, but also to become the head of the government. Although it is generally agreed that Guchkov had no political ambitions and simply provided a "mechanism of the revolution," analysis of his political activities in 1915-17 allows the author to conclude that, contrary to the popular belief, he strove to take the helm of state. It is common knowledge that the attempt of the Octobrists' leader to head the Cabinet of Ministers was a fiasco; and yet the identified document expands our understanding of A. I. Guchkov’s personality and of the political struggle at the highest political and administrative level of the Russian Empire in the days of the February Revolution.
Efecto de μmáx de cepas Leuconostoc mesenteroides en fermentaciones simuladas
Authors: Díaz-Montes Elsa
Published: April 2023

Las fermentaciones son procesos bioquímicos en los que bacterias transforman sustratos en productos y metabolitos de interés comercial. Las bacterias ácido-lácticas (BAL) son microorganismos que producen ácido láctico a partir de fructosa y glucosa, sin embargo, al cultivarse en medio con sacarosa el producto principal es el dextrano. Este exopolisacárido tiene propiedades gelificantes, espesantes y reológicas importantes para el área alimentaria y médica. Al igual que en todos los procesos fermentativos, la producción de dextrano se ve afectada por las condiciones del medio como el pH, temperatura y sustrato, y además la cepa productora. Por lo anterior, el objetivo del trabajo fue predecir el efecto de la μmáx de trece cepas de Leuconostoc mesenteroides en su crecimiento celular, consumo de sustrato y producción de dextrano en procesos fermentativos. Los resultados mostraron que la simulación es una herramienta valiosa para visualizar comportamientos cinéticos y poder encontrar y seleccionar los parámetros óptimos para ejecutar fermentaciones reales con resultados exitosos.

Se estudió el impacto de la salinidad, expresada en términos de fuerza iónica (I [mol L⁻¹]), sobre el valor del pH obtenido con diferentes electrodos combinados de vidrio comerciales que fueron calibrados con disoluciones amortiguadoras diseñadas por nuestro grupo. Así, se prepararon y utilizaron tres disoluciones amortiguadoras de calibrado con I = 0.10 mol L-1 y seis con I = 0.72 mol L-1 impuesta con NaCl, con el objetivo de emular el efecto de una matriz marina. Éstas fueron tituladas potenciométricamente y los registro pH vs. v fueron analizadas mediante un método sin aproximaciones que emplea un ajuste polinomial de tipo no lineal y sin segmentación, generado a partir del balance de electroneutralidad único para cada uno de los ensayos. De tales ajustes se obtuvo la concentración molar efectiva de las especies ácido – base que conforman cada disolución amortiguadora, su valor de pKa, el valor del pH exacto de estos amortiguadores bajo condiciones de salinidad elevada, así como el valor del pKw del disolvente.

Los ácidos húmicos (AHs) son los componentes principales y más abundantes de la materia orgánica (MO). En este estudio se realizó una evaluación de AHs mediante parámetros espectroscópicos, posteriormente a un proceso de aglomeración, coagulación y microfiltración en presencia de hierro (Fe3+) como agente coagulante y mediante la cuantificación por el método de calibración. También se analizó fisicoquímicamente el comportamiento de la macromolécula de húmico en presencia del metal, ajustando el pH a 5, condición a la que se lleva a cabo la deprotonación de los grupos carboxílicos (-COOH), estabilizando las cargas negativas con una concentración mínima pero efectiva de la sal de Fe3+(3 mM). Mediante este proceso se logró eliminar un promedio del 96% de AH como MO en solución. Las cinéticas del proceso de interacción AH-Fe se desarrollaron en tiempos cortos, menores a los 5 min. No obstante, los espectros presentan una gran similitud en relación con las absorbancias, sin embargo, es recomendable llevar a cabo la microfiltración en los primeros 30 min de reacción.

This paper uses alchemical metaphor to examine the psychological challenges United States military veterans face as they attempt to reintegrate into civilian society. The arc of the research tracks a military member’s progression from Basic Training to the transition back into civilian life. In particular, it pinpoints the psychological harm inflicted by the military’s collective consciousness on the individual psyche. Examining the process of military training from the perspective of a Jungian understanding of the psychological stages of alchemy, the paper illuminates a process that presents each military member with profound difficulties related to identity, the ability to engage in a vibrant relationship with the Self, and the ability to reenter civilian life. In conclusion, it highlights the need for civilians, elected officials, and the mental healthcare community to help military veterans address the psychological pain of their service through practices that support their adjustment to civilian life from a holistic perspective that includes image, soul, and conscious connection fostered between the ego and archetypal forces that animate human life.

Desa Teros merupakan salah satu desa yang terletak di Kabupaten Lombok Timur, tepatnya di Kecamatan Labuhan Haji, pun ikut menjadi sasaran pemerintah dalam upaya pencegahan dan penekanan angka stunting. Kabupaten Lombok Timur juga tak luput dari perhatian mengingat jumlah penduduknya yang cukup padat dan tingkat kesadaran masyarakat terhadap isu stunting ini relatif rendah. Perlu diketahui stunting adalah kondisi gagal tumbuh pada anak balita (bayi dibawah 5 tahun) akibat dari kekurangan gizi kronis sehingga anak terlalu pendek untuk usianya. Kekurangan gizi terjadi sejak bayi dalam kandungan pada masa awal setelah bayi lahir, akan tetapi kondisi stunting baru nampak setelah bayi berusia 2 tahun. Kondisi gagal tumbuh tersebut kemudian dapat mengakibatkan berbagai gangguan kesehatan baik jangka pendek maupun jangka panjang. Salah satu contohnya akan berimbas pada IQ anak. Dengan demikian dapat dicermati bahwa dampak yang ditimbulkan oleh stunting akan memberikan pengaruh untuk anak seperti menurunkan keoptimalan kognitif, motorik dan kesehatan yang berimbas pada kapasitas dan kemampuan anak dalam menyerap pelajaran di sekolah kemudian mempengaruhi produktivitas dan kemampuannya saat dewasa. Berdasarkan tujuan-tujuan dari program Pemerintah Daerah, serta melihat tingginya tingkat stunting di Kabupaten Lombok Timur, kegiatan ini dimaksudkan untuk membantu instrumen-instrumen Desa Teros terkait seperti Tokoh Agama, Tokoh masyarakat, Pemerintah Desa, Pembinaan Kesejahteraan Keluarga (PKK), Kader Posyandu, Bidan Desa, Karang Taruna serta masyarakat pada umumnya untuk menekan angka stunting di Desa Teros, Kecamatan Labuhan Haji, Kabupaten Lombok Timur melalui pelaksanaan sosialisasi- sosialisasi  yang tujuannya untuk meningkatkan kesadaran masyarakat

Salah satu permasalahan dalam transportasi adalah kecelakaan lalu lintas. Salah satu penyebabnya adalah ketidak-tertiban dari sikap pengendara sepeda motor di ruas jalan karena akan mengganggu kendaraan lain berpotensi untuk menyebabkan kejadian kecelakaan dan pelanggaran lalulintas meningkat dari tahun ke tahun. Pengendara motor di Kota Mataram dari sejak usia dini sampai mampu mengendarai kendaraan bermotor belum memiliki pemahaman yang baik tentang tata cara berlalulintas yang tertib di jalan raya serta berkeselamatan yang tinggi. Pembelajaran pengenalan perangkat keselamatan berlalulintas dijalan raya sejak usia dini adalah suatu bagian yang cukup penting dilakukan, sehingga pada saat mereka dewasa dan sebagai pengendara atau pengguna sepeda motor sudah memiliki pemahaman berkeselamatan dan kemampuan pengendalian kendaraan secara lebih baik. Metode pemberian pembelajaran atau penyuluhan tentang pengenalan fasilitas keselamatan berlalulintas di jalan raya dan tata cara berlalulintas dijalan, melalui cara bermain sambil belajar, tentu adalah metode efektif dalam penyampaian target capaian yang diharapkan. Namun karena masih usia dini, ada sedikit kesulitkan dalam menarik fokus perhatian mereka yang lebih lama. Metode seperti ini untuk anak usia dini harus terus-menerus disampaikan secara berkesinambungan agar potensi pelanggaran dalam berkendaraan dijalan raya yang berdampak pada kecelakaan saat mereka dewasa dapat diminimalisir, sehingga secara tidak langsung terciptanya tertib berlalulintas di wilayah Kota Mataram dapat lebih terwujud.
Exploring ‘spaces for community dialogue’ among adults and children in collective identification, sharing and mitigation of HIV/AIDS concerns in Uganda
Authors: Mbooge Najjuma Saidah , Kyaddondo David
Published: April 2023

Background

Through experience and research, the Uganda government perceived the HIV/AIDS pandemic as a multi-dimensional problem and practically demonstrated that multi-sectoral and multidisciplinary interventions are the best approaches to address this. This calls for collaborative efforts among all stakeholders with respect to their mandates, areas of comparative advantage and expertise. In this study, we explored the role of ‘spaces for community dialogues’ among adults and children in the collective identification, sharing and mitigation of HIV/AIDS concerns in Uganda.

Methods

This was an ethnographic study conducted between 2009 and 2015 in two purposively selected districts most hit by HIV/AIDS. We employed multiple data collection methods, including participant observation, in-depth interviews, focus group discussions, participatory rural appraisal and key informant interviews. Ethics clearance was obtained from Makerere University, College of Humanities and Social Sciences, and from the two social support agencies. Data were synthesised and analysed using thematic analysis.

Results

Findings show that bazaars, mother or father talks, testing sites and regular spaces, banana beer parties, village meetings, school settings, and community events provided safe environments for interaction about HIV/AIDS concerns among children and adults. Children expressed their views through visual techniques with the support of adults. The use of catalysts facilitated effective interactions by harmonizing experiences of those directly impacted by HIV/AIDS and those providing the needed helping skills.

Conclusion

Dialogue is an act of creations that cannot be consumed by participants. Spaces for dialogue are real sites that societies use in their daily interactions. Children are active participants in the struggle to mitigate the adverse effects of HIV/AIDS. Despite differences in ways of sharing messages, spaces in a community settings were deemed appropriate for dialogue on HIV/AIDS issues.

En tomate (Solanum lycopersicum L.), las plantas injertadas pueden conducirse a más de un eje, siendo de interés discriminar si las respuestas se deben al portainjerto o a la forma de conducción. Este trabajo tuvo como objetivo estudiar el efecto del injerto y el número de ejes por planta sobre su comportamiento fenológico y productivo. Se condujeron dos ensayos bajo un invernadero metálico parabólico de 24x40 m en La Plata, Buenos Aires, Argentina (33°56'42,6”S, 60°33'35,6”W), evaluando: 1) Planta: ‘SVTH 2900’ sin injertar, autoinjertado e injertado sobre ‘Multifort’; 2) Ejes por planta: uno, dos, cuatro. El diseño fue en bloques completos aleatorizados con arreglo factorial 2x3 con 3 repeticiones (2020) y 3x3 con 4 repeticiones (2021). Se registraron los días y grados-día acumulados desde trasplante, rendimiento y peso medio de frutos. Los datos fueron analizados usando un análisis de varianza y prueba de Tukey. No hubo diferencias en el momento de inicio de cosecha, y el ciclo productivo se prolongó por el injerto y el mayor número de ejes. El injerto incrementó el peso medio de frutos, el rendimiento total en 32 a 34% y la producción de frutos con peso >150 g en 45%. La conducción a dos ejes promovió el rendimiento total. Además, el número de frutos fue superior en plantas a dos ejes en 2020, mientras que aumentó en plantas injertadas conducidas a cuatro ejes en 2021. En las condiciones de ensayo, puede recomendarse el uso de plantas injertadas y la conducción a dos ejes, ya que se observa un mejor comportamiento fenológico y productivo.

Co-designed Practical Use of Probabilistic Climate Advisories among Smallholder Farmers: A Balance between Confidence and Caution
Authors: Mwangi Mary , Kituyi Evans , Ouma Gilbert
Published: April 2023

Especially for smallholder farmers with limited land and financial resources, farming in arid and semi-arid lands (ASALs), where season-to-season rainfall fluctuation dictates production, is a risky business. Through participatory approaches, this study compares deterministic and probabilistic interpretations of climate forecasts and their use by smallholder farmers through a crop-growing season. The study revealed that deterministic advisories are good for smallholder farmers only when formulated from forecasts with higher accuracy than the historical climatological distribution. Otherwise, they cause farm loss in terms of labor and inputs. On the other hand, probabilistic advisories help farmers spread the risk to cater to all the uncertainty and in so doing bring out a balance between confidence and caution. However, farmers must be supported with enough sensitization to comprehend forecast probability, translate it into probabilistic advisories and use that to plan and manage farm activities. The findings support the hypothesis providing packaged climate products in transparent probabilistic terms in place of deterministic form can overcome inherent credibility challenges. The study’s conclusion highlights important takeaways and new understandings of the advantage of using probabilistic advisories among resource-poor smallholder farmers.
The Refractive Effect of k-Factor on Radio Propagation over Lokoja, Nigeria

Published: April 2023

The effective earth radius factor (k-factor) has a refractive propagation effect on transmitted radio signals thus making its study necessary for the proper planning of terrestrial radio links and power budget. This study was carried out over the city of Lokoja, Nigeria, using ten years (2011 to 2020) atmospheric data of temperature, pressure and humidity both at the surface (12 m) and at 100 m AGL. The data were retrieved from European Centre for Medium-Range Weather Forecasts (ECMWF) ERA5. The k-factor yearly variation follows the same trend with minimum and maximum values obtained during dry and wet season months respectively. In addition, the highest mean value of 1.00042 was recorded in the month of August while the lowest value of 1.00040 was recorded in the month of January with an overall mean value of 1.0003. This value is less than the recommended standard of 1.33 by ITU-R. The propagation effect corresponding to k < 1.33 is sub-refractive. The implication of this on radio wave propagation, especially terrestrial communications is that transmitted wireless signal is prone to losses. This can be mitigated through an effective power budget: Choice of transmitting antenna’s height and gain, so as to improve the Quality of Service over the study area.

Anemia is a global public health problem affecting both developing and developed countries, it occurs at all stages of life but is more prevalent in pregnant women and young children. It is one of the commonest associations in patients of heart failure and has been shown to be associated with increased mortality in both acute and chronic heart failure. Conventional drugs (Vitamin B12, Ferrous preparations) used in the management of anemia are either unaffordable or unavailable and may still have undesirable side effects (abdominal discomfort, dry mouth, nausea, constipation). While herbal medicines that are in use are cheap and are thought to be readily available and less toxic. The need for less expensive, and safe management options has stimulated a surge in continuous research towards the use of herbal medicine for the treatment of anaemia. Most of herbal resources used in anaemia management have not been scientifically validated for their claim, and there is paucity of literature on the phytochemial constituents and Mechanism of action. The goal of this review is to expound various plants used for the treatment of anaemia with their phytochemical properties and mechanisms of action in experimental animal models. Twenty one plant with antianaemic activity were thoroughly sought and their findings reviewed. This information will create a center of attention for scientists and consequently play a major role in future research and documentation of herbal resources in the treatment of anaemia. However, Scientists are therefore encouraged to isolate and characterize these medicinal plant.

ORGANIZATION OF THE LOGISTICS PROCESS OF CARGO HANDLING
Authors: DIKAN О. , KUDRIAVTSEVA O.
Published: April 2023

The paper establishes that the logistics process in a warehouse includes a technological process of cargo handling, which covers the totality of all main and auxiliary operations carried out in a certain sequence. The success of the rational organization of the technological process in a warehouse is closely related to the optimal selection and implementation of the warehousing system, which determines what technical means will be used for each operation. In addition, it has been found that the biggest problem that exists in a warehouse when managing the cargo handling process is the connection between material (commodity) and information (document management) flows. Therefore, in order to improve this process, the paper proposes a functional model of the logistics process of cargo handling in a warehouse that will allow for a visual demonstration of the interconnected promotion of material (goods flow) and information flows through the warehouse. In addition, in order to optimize management decision-making, analysis and monitoring of logistics costs, the paper provides an appropriate decomposition of the logistics process of cargo handling by the main groups of operations: unloading, receiving and warehousing, picking, shipping and delivery. Thus, the rational implementation of the logistics process in a warehouse is the key to the warehouseʼs profitability. Therefore, a rationally organized logistics process in a warehouse will help to achieve: rational warehouse planning when allocating work areas, which helps to reduce costs and improve the cargo handling process; efficient use of space when placing equipment, which will increase the warehouse capacity; use of universal equipment that performs various warehouse operations and significantly reduces the fleet of lifting and handling machines; minimization of intra-warehouse transportation routes in order to reduce operating costs.

To achieve this goal, a number of contemporary general scientific methods and research techniques have been used, namely: abstract and logical, including analysis and synthesis, induction and deduction; clarification of the essence of basic concepts and categories, generalization – for reviewing information sources, studying domestic and foreign experience; system analysis – with the aim of a holistic perception of the object of research and a comprehensive analysis of the links between elements within the defined problem as a whole; problem-oriented – for scientific substantiation of the system.
Ensuring the stable and dynamic development of enterprises over the past quarter of a century has become an important and significant priority for the management of transport enterprises, including strengthening of the international authority of the country, increasing the competitiveness of products and Ukraineʼs accession to the EU. To ensure consistency in the procedures for regulating economic instability, the article presents a system for managing the stable development of a transport enterprise. Also, the article forms a model of management of stable economic development of transport enterprises, which includes: determination of the need for rehabilitation; coordination of goals, objects and subject of management; building a set of methods and tools of management, taking into account compliance with the goals and factors; determination of the need for resources; ensuring organizational compliance of the management mechanism; evaluation of results and adjustment of the management mechanism. The application of this methodology strengthens the company management system by providing a vision of values and motives, guidelines and threats; identifying conditions that may be a motive or a barrier to work.
The theoretical conclusions, approaches and recommendations proposed in the article can be used to develop a systematic and methodological support for the selection of tools and technologies for regulating the economic sustainability of transport enterprises.
Modelos predictivos de preservación ósea diferencial en la cuenca media e inferior del río Paraná basados en propiedades físico-químicas de los suelos

Published: April 2023

En el centro-este de la provincia de Santa Fe (departamentos San Jerónimo, La Capital y Las Colonias) la mala preservación ósea constituye un rasgo característico del registro arqueológico regional. Por este motivo, durante la última década se encuentra en desarrollo una investigación orientada al estudio de la diagénesis ósea a diferentes niveles de organización de los huesos. Parte de la misma estuvo centrada en la generación, mediante el uso de sistemas de información geográfica (SIG), de modelos espaciales de preservación ósea diferencial basados en las propiedades de los suelos. Los modelos generados han sido evaluados, y continúan siéndolo en el presente, con información obtenida del análisis de restos óseos recuperados en sitios arqueológicos del área. En este marco, el objetivo de este trabajo es presentar y discutir versiones ampliadas de tales modelos espaciales para un área que incluye la cuenca media e inferior del río Paraná (provincias de Santa Fe, Entre Ríos y Buenos Aires), con el objetivo de proporcionar un marco adecuado para interpretar la variación en las condiciones de preservación ósea en el sur de la región del Litoral argentino.
Dos reflexiones en torno a la tecnologia lítica en Colombia
Authors: Aceituno Francisco Javier , Loaiza Nicolás
Published: April 2023

Como en otras regiones americanas, en Colombia la tecnología lítica ha ocupado un lugar central a la hora de documentar y caracterizar las ocupaciones humanas antes de la aparición de la alfarería. El objetivo del presente artículo es hacer una revisión de dos temas de la arqueología temprana colombiana mirados desde la tecnología lítica. El primero, el poblamiento pleistoceno de Colombia. En este apartado se analiza la relación de la tecnología lítica con las estrategias de subsistencia, y con potenciales movimientos démicos en el Noroccidente de Suramérica durante el Tardiglacial. El segundo, los cambios adaptativos relacionados con la llegada del Holoceno. En esta segunda parte, se analizan cambios en las estrategias de subsistencia, a partir del análisis de las azadas, uno de los artefactos más representativos de la geografía colombiana, vinculado al uso temprano de plantas y a los orígenes de su cultivo.
Balance crítico de la antropología legal de Bronislaw Malinowski
Authors: Quetglas Molina Augusto Joaquín
Published: April 2023

El artículo recorre la producción intelectual de Bronislaw Malinowski sobre la ley en los pueblos “primitivos”, atendiendo principalmente a la recepción de su trabajo en el campo de la antropología legal. Revisamos el análisis malinowskiano del derecho, destacando el lugar que éste ocupa dentro de la teoría funcionalista, las innovaciones teóricas y metodológicas que presenta respecto a los antecedentes en la materia, y algunos conceptos particulares que fueron posteriormente objeto de debate. Reunimos luego las objeciones más frecuentes a la antropología legal de Malinowski dentro de la literatura específica, examinando cuatro tipos de críticas: primero, aquellas que atacan la extensión dada al concepto de ley; segundo, las que se dirigen a cuestionar la pertinencia de la distinción entre derecho civil y criminal; tercero, las que señalan la hipertrofia racional que Malinowski creía encontrar en los nativos; y por último, las múltiples objeciones a la coherencia y continuidad de las definiciones de Malinowski a lo largo de sus escritos.

STUDY OF CHEMICAL AND PHYSICAL FEATURES OF LIGNITE DERIVATIVES FOR EVALUATION OF THEIR HYBRID FUNCTIONALITY POTENTIAL © V.V. Lebedev, PhD in technical sciences, D.V. Miroshnichenko, Doctor of Technical Sciences, D.O. Savchenko, E.I. Lytvynenko, PhD in technical sciences (National Technical University «Kharkiv Polytechnic Institute», 2 Kyrpychova Str., Kharkiv, 61002, Ukraine)) The article shows that despite the existence of studies on the modification of various types of polymeric materials with lignite and its derivatives (in particular, it has been proven that the addition of lignite to polymers can affect their biodegradation), there is a further need to study the physicochemical features of the hybrid functionality of these materials in relation to a wide range of materials. The paper analyzes lignite and its derivatives in the form of humic acids in terms of their use for hybrid modification of multifunctional materials. The subject of the study is related to the non-energy and non-fuel use of fossil coal. This area is one of the most promising, as it allows to obtain marketable products of high demand, the cost of which is much higher than the cost of the raw materials. By performing qualitative, quantitative, and spectroscopic analyses of humic acids of different types of lignite, it has been proved that they have a significant hybrid functionality due to the presence of a large number of different functional groups in their composition. It has been shown that the most characteristic functional groups of lignite humic acids include phenolic hydroxyl -OH groups, carboxyl COO-, NH2 deformation groups, aliphatic CO groups, etc. This determines the ability of lignite humic acids to act as hybrid modifiers in relation to a wide range of substances through the following mechanisms: chemical interaction, dipole-dipole interaction in the form of hydrogen bond systems, and configuration changes in the structure of various materials and substances. It has also been found that the high hybrid functionality of lignite humic acids is determined by their polarity, which significantly increases the reactivity of active peripheral groups. Keywords: coal, humic acids, hybrid functionality, modification, properties. Corresponding author Denys V. Miroshnychenko, e-mail: dvmir79@gmail.com
Coke dry cooling plant excess gas utilization.

COKE DRY COOLING PLANT EXCESS GAS UTILIZATION © S.A. Kravchenko, PhD in Technical Sciences (STATE ENTERPRISE "STATE INSTITUTE FOR DESIGNING ENTERPRISES OF COKE OVEN AND BY-PRODUCT PLANTS'' (SE "GIPROKOKS'')", 60 Sumska str., Kharkiv, 61002, Ukraine), D.V. Miroshnichenko, Doctor of Technical Sciences (National Technical University "Kharkiv Polytechnic Institute", 61002, Kharkov, Kirpichev str., 2, Ukraine) At coke-chemical enterprises, that operate coke dry cooling plants, due to the peculiarities of the technology, an excess of circulating gas is formed, which must be constantly removed from the closed circuit. This article examines two operating plants designed for the utilization of excess circulating gas, and also presents some experience of their exploitations. In particular, information is provided on the method of disposal of excess circulating gas of coke dry cooling plants in an additional boiler by burning it in a mixture with coke gas. The main equipment of the recycling unit is a KO-10 steam boiler with forced circulation and a U-shaped arrangement of heating surfaces, located in the building of the boiler coke dry cooling plant of coke batteries of one of the coke-chemical enterprises. Tests and operation of the plant confirm the possibility of producing a couple of energy parameters on it with the achievement of high environmental indicators as a result of the utilization of excess gas of the coke dry cooling plant. The second direction considered is the use of excess gas from the coke dry cooling plant as fuel. The possibility is shown of increasing its calorific value as a result of mixing circulating gas with gas of higher calorific value – in particular with blast furnace gas. It is shown that the existing positive experience of operating the mentioned installations allows recommending both directions for the utilization of excess circulating gas for use on existing and newly designed coke dry cooling plants. According to the article, the work experience, a lot of experiments and performed calculations indicate the expediency of maintaining the regime with the maximum permissible content of CO in the circulating gases during the operation of the coke dry cooling plants. This allows to increase the quality indicators of coke. The high content of CO in the circulating gases also makes it possible to significantly reduce losses from coke burning in the process of dry cooling. Keywords: coke dry cooling, recovery boiler, circulating gas, excess, utilization, additional boiler, increase in calorific value, CO content, coke quality. Corresponding author S.O.

How Refugees Respond to Anti-Refugee Elite Discourse: No Exit, But Less Voice
Authors: Secen Sefa , Öztürk Aykut
Published: April 2023

How do elite discourses about refugees impact refugees’ political integration and intentions on return? In this study, we answer this question through an original survey experiment conducted with 3,992 Syrian refugees living in Turkey and Germany. We find low political interest and support for political participation among Syrian refugees in general. Our experimental results indicate that the anti refugee elite discourse weakens these already low levels of political interest and support for political participation. However, contrary to our expectations, our findings suggest that the anti-refugee elite discourse does not significantly impact refugees’ intentions on return. We conclude that the hostile political environment in host countries undermines refugees’ political integration.
