11 июля 2023 года исполнилось ровно 165 лет талантливому казахскому поэту, писателю, композитору, философу-мыслителю, ученому-историку ШаһкеримуКудайбердыулы. Следует отметить, что с момента реабилитации Шаһкерима Кудайбердыулы была проведена значительная работа по исследованию его творчества и деятельности. Несмотряна то, что среди ученых была проделана колоссальная работа, есть моменты, на которых стоит остановиться и уделить особое внимание.В данной статье автором впервые проведен анализ произведений Шаһкерима. Врезультате исследования удалось определить три исторических персонажа, которые имели быть место в творчестве поэта. Поэт использовал их имена в казахском правописании того времени: Галантный джентельмент англо-саксонского происхожения, выступающий как прообраз выражения меценатской деятельности состоятельных казахов конца XIX - начала XX вв. Альфред Гвинн Вандербильт І в творчестве известен под именем «Уолдер Белдет». Хишам ибн Абдул-Малик – омейядский халиф известен у Шаһкерима под именем «Ашам патса», с которым вступил в неравный диалог умудренный степняк, оказав достойное сопротивление,выйдя победителем. Ань Лушань кочевник-дипломат, который заставил содрогнуться всю Танскую империю, известный у поэта как Пан-Жи-Зан хан. В произведениях Шаһкерима имеется ряд личностей, которые требуют дальнейшего выяснения. Это будет возможным благодаря изучению других источников, которые использовал поэт в своих исследованиях.

Navigating Trust and Safety in Multi-Agent Reinforcement Learning: Attacks, Defenses, and Future Directions
Authors: Divya Challa
Published: October 2024

Multi-Agent Reinforcement Learning (MARL) is a key framework for building intelligent systems where multiple agents operate within a shared environment, with applications spanning autonomous driving, robotics, and distributed control systems. However, real-world deployment of MARL brings significant trust and safety challenges, as these systems are susceptible to a range of attacks that can compromise their robustness and reliability. This paper provides a comprehensive review of trust and safety attacks in MARL, categorizing various types of attacks and their implications. We explore existing defense mechanisms designed to mitigate these threats, highlighting their strengths and limitations. Additionally, we identify open challenges that remain unaddressed and propose potential future research directions to enhance the robustness and security of MARL systems.

A Study of the Impact of English Tests Anxiety on the Development of Language Learning in Foreign Language Contexts
Authors: ناظم مظلوم هاشم
Published: October 2024

The study aims to explore the impact of anxiety on English learning for preparatory schools students in Iraq, specifically by revealing a strong connection between anxiety and academic challenges in the official context. Sixty-four participants (male and female) were randomly selected from the preparatory schools. The study discovered significant differences in the rates of learning English as a foreign language. The participants indicated a strong relationship between English tests and anxiety in classroom activities. The Chi-square test showed a positive relationship between the two variables: anxiety and speaking skills  c2 (63,1),11.00=.003, p<0.05. On the contrary, the Chi-Square test revealed a negative correlation between anxiety and language skills, including listening, reading and writing skills, respectively. In comparison, the results demonstrate that the likelihood of females suffering an anxiety disorder is not statistically significantly higher compared to the case of males (t=.089, Sig.=.930). The participants obtained the lowest mean scores for the four language skills. Based on the responses provided by 31% of the participants to the FLCAS questionnaire (M= 25.3, SD= 3.2), speaking emerges as the most challenging skill for foreign language learners in preparatory schools. The study's recommendations underscore teachers' critical role in alleviating the adverse impact of anxiety on learning. Specifically, it suggests that teachers should identify the root cause of the anxiety and assist students in coping with anxiety while engaging in academic activities. Furthermore, they should establish a safe atmosphere for English learning, which could prove vital for future studies.
Evaluating the Effectiveness of Songs in Advertisements: A Cognitive Stylistic Study
Authors: حسين حويل غياض
Published: October 2024

Advertisements fulfil a significant role in social life by directing and guiding consumer actions and practices and shaping cultural norms. They not only support products and services but also reproduce and strengthen societal standards and norms. This paper explores the functionality of songs used in advertising within the field of cognitive stylistics. This field of research offers useful information into how cognitive processes and linguistic choices interact to form the interpretation and influence of discourses. The research questions are: (1) How do cognitive stylistic features enhance the influence of songs on advertising? (2) How do cognitive stylistic features shape customers' attitudes and behaviours? To examine the research questions, this paper uses a qualitative analysis method. The data is made up of a song used in advertisements, which will be investigated to detect cognitive stylistic elements and their influence on consumer viewpoints and behaviors. We hypothesize, through applying the mixed cognitive stylistics model, that the manifestation of cognitive stylistic aspects in songs enriches their functionality in grasping and captivating the intended audience. The findings have themes for advertisers, offering perspectives on how to successfully interact with their target audience through songs and how to evaluate the effectiveness of their advertising efforts.

The Neoliberal Legal Systems and the Implications for Madrid’s Urban Spaces
Authors: Sanchez Alvarez Eva
Published: October 2024

This paper explores the topic of social justice and the Right to the City as experienced through the enforced regulation ‘Gag Law’ in Madrid. This policy has been explored up-taking a Foucauldian view-use and organisation of space, and using the concept of the Right to the City developed by Lefebvre. Hence, the ‘Gag Law’ has aimed to prohibiting undesirable protests, restraining political rights and the right to protest. Evaluating the case study of Madrid, results demonstrate that the fusing control and the claim to ‘community safety’ of neoliberal agendas, caused a shrinking of democratic rights in the Spanish city. The main objective has been to stress the importance to allow for a deeper understanding of urban policy implications on citizen’s rights.
Towards Socio-Spatial Equity in Public Space
Authors: Tallavajjula Naga Sneha
Published: October 2024

Street vending has historically driven and dominated the informal economy in the Indian city of Hyderabad. The inception of urban migration saw a range of marginalized groups move into the city, creating stark rural-urban differences and causing residents and the city to struggle to adapt. They eventually established themselves along the river to meet daily needs and adopted street vending as a means of occupation toward sustenance. While urban design in the city actively excludes these vendors from urban belonging, they retaliate through subversive practices and tactical urbanism to impose belonging, in a quest to find their right to the city. Neoliberal policies continue to distance these disengaged communities from the city considering them undesirable through dominant concepts of unattractiveness. While the government disapproves of informal vending in the public realm in Hyderabad – especially along the Musi River – branded designer “pop-up stores” and gourmet food stalls are encouraged, advertised and publicised. Inequitable law enforcement has created turmoil in the access and right to public space in the city. This study highlights the need for strategic placemaking to build healthy relationships and equity in the city. Various perceptions of public space among street vendors are analysed to help integrate these disengaged residents in the city. The paper concludes with empirical findings for designers and planners to examine, in delivering a customized design plans articulated to prevent further distress to micro-urbanism patterns existing in the city and its urban fabric.
The Relationship between Park Design and Seniors’ Use of Green Spaces in X’ian, China
Authors: Zhang Yang , Van Dijk Terry , Weitkamp Gerd , Van den Berg Agnes Elizabeth
Published: October 2024

Urban parks can facilitate a healthy and active lifestyle among older adults by promoting their physical activities and social interactions. However, unless these parks meet the needs of this group, they may not be effectively utilized or contribute to seniors’ well-being. We applied the concept of environmental affordances in an investigation of the relationship between urban parks’ design characteristics and their use by older adults. Specifically, we developed a functional taxonomy of afforded park usage for senior visitors based on a methodology that combined interviews and behavior mapping in three sites within an urban park in Xi’an, China. We identified four main categories of afforded park usage: individual physical activities, group physical activities, social interactions, and sitting and resting. These activities may be supported or constrained by particular design elements, other people and their behaviors, the park’s physical accessibility, facilities and maintenance, and the park’s atmosphere. In conclusion, we provide recommendations to facilitate urban planners and designers in creating more livable green spaces for senior residents in urban areas.
The “In-Between” Development and Heritage
Authors: Teba Tarek , Merchak Namitta , Chamoun Rachid
Published: October 2024

Batroun is a historic Mediterranean coastal city in North Lebanon and exemplar for long-term impact of haphazard urban expansion on (in-)tangible heritage. The long-term development of transport infrastructure has contributed to Batroun’s contemporary urban structure and the weak connections between its entities and with the sea. As a result, Batroun’s old town is gradually disconnecting from the coastline and inland developments, and its traditional socioeconomic practices are declining. This has triggered negative spatial, social and economic outcomes on the town’s public spaces and identity.This paper, therefore, seeks to evaluate the impact of infrastructural development on the social, economic, and spatial aspects of the historic town of Batroun. It investigates the opportunities that arise from the city’s cultural heritage landscape and how these opportunities inform revitalising the lost socio-economic values and identity of the old town. For this purpose, field observations were conducted to investigate Batroun’s urban and spatial setting. Also, Interviews were conducted with stakeholders, experts and local communities in order to define problems and their impact on (in-)tangible heritage from top-down and bottom-up perspectives. By mapping findings, this research assesses the consequences of a developed transport infrastructure on everyday life and the town’s historic built environment.The heritage of Batroun has been seen as a barrier to the city’s development, and the regeneration of the old town has largely focused on the preservation of tangible dimensions, ignoring the contribution of intangible heritage settings to the revival of the old town and its socio-economic practices. Understanding Batroun’s heritage capacities and contemporary social values can facilitate the way for local stakeholders and communities to inform the revitalisation process. Thus, inclusive and collaborative approaches and new tools of inclusion can improve heritage-informed regeneration strategies and help define appropriate infrastructure for a resilient development of the historic built environment.
On Top of Sustainability
Authors: Frandsen Peter Christian , Landau-Donelly Friederike
Published: October 2024

This article examines the role of cultural events in Rotterdam’s urban sustainability transition by looking at the festival Rotterdamse Dakendagen [Rotterdam’s Rooftop Days]. During this week-long festival, rooftops are used by citizens and cultural groups to activate urban spaces as places of learning, exchange, and DIY urbanism, thus broadening the scope of rooftops as places for cultural sustainability. Drawing on empirical material collected via qualitative interviews, policy document analysis, and five months of participant observation, we identify three aspects that inform urban sustainability transitions via culture: (1) the (re)activation of rooftops via cultural programming, (2) institution-building that is mindful of festivals’ continuously temporary nature, and (3) the limited material, yet wide-ranging immaterial effects of urban cultural festivals that have accelerated the Rotterdam’s urban (cultural) politics of sustainability. In sum, the article argues that culture plays an important role in any investigation of urban sustainability transitions and should be considered with more conceptual nuance in the future.

Restorasyon çalışmaları sırasında, kilisenin naosundaki çimento harçlı zemin taşları kaldırılmış, altta önceki evreye ait in situ yer döşemeleri ortaya çıkmıştır. Liturjik işlevli ambon ve soleanın tahrip olmasının ardından olasılıkla zeminde oluşan açıklıklar sonraki evrede niteliksiz yer döşemeleri ile kaplanmıştır. 2022 yılında restorasyon çalışmalarında ortaya çıkarılan bu in situ yer döşemelerine istinaden naosta beş sondaj çalışması gerçekleştirilmiştir. Sondajların amacı; kilisenin farklı yapı evrelerini tespit etmektir.
Bu çalışmada 2022 yılında Aziz Nikolaos Kilisesi’nin naosunda gerçekleştirilen sondajlarda elde edilen verilerin ön değerlendirmesi sunulmuş; bugüne kadar yapılan çalışmalarda araştırmacılar tarafından önerilen kilisenin yapı evreleri ve tarihlendirmeye ilişkin tartışmalara açıklık getirilmeye çalışılmıştır. 2022 yılında elde edilen veriler, bazı önerileri desteklerken, önceki çalışmalara yeni ve önemli bilimsel katkılar sunmuştur.
Aziz Nikolaos Kilisesi’nin mimarisi üzerine yapılan önceki çalışmalarda üç ana inşa evresi belirlenmiştir. Bazilikal planlı I. yapı evresi 529 yılındaki büyük deprem sonrasına tarihlendirilir. 2022 yılında naosta gerçekleştirilen sondajlarda ise olasılıkla üçü inşa ve ikisi onarım olmak üzere beş yapı evresi tespit edilmiştir. Sondaj çalışmalarının en önemli sonuçlarından biri, 6. yüzyıla tarihlendirilen bazilikal planlı yapının zeminlerinin ortaya çıkarılması ve bu yapının Geç Roma-Erken Hristiyanlık dönemine ait bir yapı /yapılar topluluğu üzerine inşa edildiğinin belgelenmesidir. Çalışmalar sonunda, 1. evre olarak tanımladığımız bu yapının zemininde geometrik ve bitkisel motifli opus tessellatum tekniğinde mozaikler ortaya çıkarılmıştır. Bu mozaiklerin Aziz Nikolaos Kilisesi’nin erken bir evresine mi veya azizin martyrionuna mı ait olduğu gelecekteki kazı çalışmalarıyla aydınlatılacaktır.

Camdan yapılmış, kalıpta şekillendirilmiş, çömelir pozisyonda ve iki eli genital bölgesinde olan çıplak bir kadın figürünün betimlendiği amuletler, Hellenistik ve Roma dönemlerinde Mısır, Levant ve Kuzey Afrika kıyılarındaki antik kentlerde yoğunlaşan bir buluntu grubudur. Amulet amaçlı kullanılan bu eser grubu Anadolu’da Gaye Çarmıklı Koleksiyonu ile Sadberk Hanım Müzesi’nde bulunan üç örnekle bilinir. Özgün ve az tanınır ikonografisiyle dikkat çeken eserlerden sadece birinin buluntu yeri bilinmektedir. Amulet-1, Lydia Bölgesi sınırları içerisine giren Manisa ili, Sarıgöl ilçesi, Dindarlı köyünde ele geçmiştir. Buluntu kontekstine ilişkin kesin veri olmaması nedeniyle amuletler yayınlanmış az sayıdaki örnek doğrultusunda analoji yöntemiyle tarihlendirilmiştir. En erken örnekleri MÖ 4. yüzyıla tarihlenen amuletler Hellenistik Dönem yoğun olmak üzere Roma Dönemi’ne kadar üretilmeye devam etmiştir. Kalıp birlikteliğini düşündürecek kadar benzer olan Amulet-1 ve Amulet-2 Mısır orijinli British Museum örneğine benzerliği nedeniyle MÖ 2. yüzyıl sonu ile 1. yüzyıla tarihlenmiştir. Biçimsel farklılıkları gözlemlenen Amulet-3 için ise Geç Hellenistik Dönem tarihlemesi önerilmektedir.
Çömelen (squat) pozisyonda çıplak kadın figürlerinin Mısır’da ele geçen terracotta örnekleri araştırmacılar tarafından tanrıça Demeter mitosunda anılan “Baubo” figürüyle özdeşleştirilmiş ve günümüze kadar da bu adlandırma tartışmalı ikonografisine karşın geçerliliğini korumuştur. Kadının doğurganlığını arttıran, aynı zamanda anne ve çocuğu koruyarak toplumsal işgücünü sürdürülebilir kıldığına inanılan bu figürler Prehistorik Dönem “ana tanrıçalarına” benzer betimleme şablonuyla her kültürün yerel bereket tanrıçası ile ilişkilendirilmiştir. Bu süreçte Demeter-Persephone kültünün kadın ve doğumla bağlantısı nedeniyle “Baubo” tanımı önerilmiş, ardından Isis-Aphrodite, Omphale ve Kotys gibi yeni tanımlar da geçerlilik kazanmıştır. Aslında figürlerin ikonografik içeriği “Baubo” olarak adlandırılan figürlerden çok daha erken bir sürece giderken, amuletlerin doğum ve sonrasına dair üstlendiği koruyuculuk fonksiyonu günümüz geleneklerini anımsatacak kadar da günceldir.

Makalenin konusunu, Mersin ili Silifke ilçesinde yer alan Kızlar Hamamı Koyu’nda tespit edilen kara ve sualtı kültür varlıkları oluşturmaktadır. Dağlık Kilikya’nın engebeli ve taşlık yapısı deniz ticaretinin ön plana çıkmasınnda etkili olmuştur. Kilikya Bölgesi’nin Kıbrıs ve Levant’a yakın konumda olması jeopolitik açıdan önemli avantajlar sağlamaktadır. Araştırma sahasında; hamam (?), sarnıçlar, bağlama delikleri, bağlama babaları, Antik taş ocağı, amphoralar, günlük kullanım kapları, çatı kiremitleri, taş çapa, çiftlik evi ve kilise tespit edilmiştir. Kıyı hattında ve sualtında tespit edilen arkeolojik buluntular, Kızlar Hamamı Koyu özelinde Dağlık Kilikya’nın kıyı bölgelerinin Kuzey Suriye ve Anadolu kıyı hattı deniz ticaretinde yoğun olarak kullanıldığına işaret etmektedir. Elde edilen bilgiler ışığında Dağlık Kilikya Bölgesi’nin MÖ 1. yüzyılda artan zeytinyağı ve şarap ticareti ile birlikte eş zamanlı olarak Kilikya Bölgesi kıyı hattında da yerleşimlerin artmaya başladığı bilinmektedir. Araştırma alanında kıyıda ve su altında tespit edilen arkeolojik buluntular, bu kırsal yerleşimin Kilikya genelinde olduğu gibi üretim ve deniz ticaretinde yoğun olarak kullanıldığına işaret etmektedir. Kızlar Hamamı Koyu’nun MÖ 1. yüzyıldan MS 7. yüzyıla kadar Kilikya Bölgesi’nin deniz ticaret zincirinin ve zahire üretim ihtiyacının bir parçası olduğu anlaşılmaktadır. Dağlık Kilikya Bölgesi'nin kıyı şeridi boyunca çok sayıda girintili çıkıntılı koy bulunmasına rağmen, bu koyların çok azında sualtı kültür varlıkları belgelenmiştir. Ancak Kızlar Hamamı Koyu’nun diğer koylara kıyasla daha yoğun buluntu içerdiği tespit edilmiştir. Bu durumun nedeni, koyun denizciliğe uygun jeolojik yapısı ile açıklanabilir. Bu bağlamda, bu çalışma Kızlar Hamamı Koyu gibi aynı jeolojik yapıya sahip az sayıda benzer koyun araştırılması için teşvik edici olacaktır.

Hellenistik Dönem’in popüler seramik gruplarından olan kalıp yapımı kâseler, genellikle yarı küresel formda, kaidesiz ve kulpsuz, dış yüzeyleri kabartma bezemeli içki kâseleridir. Hellenistik Dönem’de, Anadolu’da da popüler olan bu tür kaplar, MÖ 3. yüzyıldan 1. yüzyıl ortalarına kadar Akdeniz havzasında ve Karadeniz’de yaygındır. Atinalı çömlekçiler tarafından metal kapların pişmiş toprak taklitleri niteliğinde üretilmişlerdir. Kâselerin dış yüzeylerinde kabartma şeklinde bitkisel, geometrik ve figürlü bezemeler yer almaktadır. Kalıp yapımı kâselerde Attika ve Delos olmak üzere iki yaygın tip vardır. Bu kâseler MÖ 3. yüzyılın sonlarından itibaren Anadolu’daki yerel atölyeler tarafından da üretilmiştir; Pergamon, Sardis, Ephesos, Phokaia, Tralleis, Laodikeia, Tripolis, Sagalassos, Kibyra, Kremna, Tarsos ve Orontes (Asi Nehri) kıyısındaki Antiokheia, Anadolu’daki önemli üretim merkezlerinden bazılarıdır.
Kahramanmaraş Arkeoloji Müzesi’nde korunmakta olan kalıp yapımı kâse müzeye satın alma yoluyla kazandırılmıştır. Söz konusu kâse, özellikle duvar kısmında yer alan figürlü sahnesiyle ön plana çıkmaktadır. Bu sahnede, hoplitler, Amazonlar (?) ve Athena-Hera ikilisinin tasvir edildiği düşünülmektedir. Kâsenin yüzeyinde yan yana dizili olarak, toplam on altı figür on iki grup halinde betimlenmiştir. Figürlü kâselerde genellikle mitolojik sahneler bulunurken, Kahramanmaraş Müzesi’ndeki örnekte görülen figürlerin tam benzerine rastlanmamakla birlikte, kompozisyonun Ionia kâseleri arasında, formu, mitolojik konuları ve figürleriyle dikkat çeken Homerik kâselerle benzerliği dikkati çekmektedir. Formu ve bezemesiyle Ionia’da üretildiği düşünülen kâse, MÖ 3. yüzyıl sonları ile 2. yüzyıl arasına ait olmalıdır. Kahramanmaraş Arkeoloji Müzesi koleksiyonunda bulunan bu kâsenin ilk defa ayrıntılı olarak ele alınması ve benzersiz figürleri, Hellenistik kabartmalı kâselere yeni bir örnek eklemesi açısından önemlidir.
Large Farms in East Rough Cilicia and the Case of Asarkale

Published: October 2024

Dağlık bir topografyaya sahip olan Olba bölgesindeki küçük kırsal yerleşimler, arkeolojik çalışmaların ve yazılı belgelerin eksikliği sebebiyle tam olarak tanımlanabilir ve ayırt edilebilir durumda değildir. Kırsaldaki herhangi bir küçük yerleşimin mezra mı, köy mü veya çiftlik mi olduğunu anlamak hala güçtür. Bu belirsizlik, büyük çiftlikleri de kapsamaktadır ve tarımsal üretime yönelik kurulmuş olan bu tesisler, diğer küçük ölçekli yerleşimlerle karıştırılmaktadır. Bu karışıklık, zaten bilgi eksikliği bulunan Olba bölgesinin sosyal yapısının aydınlatılmasına hiç katkı vermediği gibi, tam tersi yönde sorunlara ve karışıklıklara yol açmaktadır.
Olba bölgesinin ortasında yer alan Asarkale’de bu kapsamda yapılan incelemeler, günümüze kadar buranın kırsal bir yerleşim merkezi olarak değerlendirilmesinin hatalı olduğunu, aslında Asarkale’nin büyük bir çiftlik olarak tanımlanması gerektiğini göstermiştir. Bunun yanı sıra Asarkale’de yapılan tespitler, Olba bölgesindeki büyük çiftlik örneklerini ararken dikkate alınması gereken parametrelerin ne tür farklılıklar gösterebildiğini ortaya çıkarmıştır. Daha önce tapınak olarak değerlendirilen yapının bir mezar anıtı olduğunun ve MS 1. yüzyıla değil, MS 2. yüzyıla ait olduğunun tespit edilmesi; yerel bir yöneticiye ait Roma evi olarak değerlendirilen yapının ise büyük bir çiftliğin villa rusticası olduğunun ortaya çıkması; geniş bir alana yayılan teraslı veya taşlardan arındırılmış tarım arazilerinin bu merkezden yönetildiğinin anlaşılması; villa rustica olarak adlandıran yapı formunun lokasyon ve plan tipi açısından nasıl şaşırtıcı özellikler taşıdığının fark edilmesi, bölgedeki diğer büyük çiftliklerin de anlaşılmasına ve tanımlanmasına yardımcı olacak tespitlerdir. Kısacası Asarkale; özellikle ilginç lokasyonu, yapı stoğu ve yapıların topografya ile ilişkisi bağlamında ele alındığında, Olba bölgesindeki büyük çiftliklerin diğer kırsal yerleşimlerden ayırt edilebilmelerini kısmen de olsa kolaylaştıracak önemli bir örnek olarak değerlendirilmelidir.

Published: October 2024

In the work the problems that arise at combustion of hydrogen in oxygen-steam mixture for the purpose of combustion products (steam) mixing for heating steam, which is planned to be used in steam turbines of power plants were researched. The main problem is the formation of underburning H2 and, accordingly, the presence of O2, which have a negative effect on metals, and it will also prevent steam condensation in the condenser was determined. For solve this problem, calculations of the equilibrium concentrations of chemical reaction products in the combustion zone depending on the amount of ballast steam added to the oxidizer (oxygen) for the initial conditions: T0=528 K, p=0.1 MPa; T0=​​528 K, p=3.1 MPa; T0=​​584 K, p=10 MPa were made. The corresponding adiabatic temperatures were calculated. The dilution of the oxidant (oxygen) with steam significantly decreases the adiabatic temperature (Tb) and reduces the equilibrium concentrations of other substances in the combustion zone, but at the same time the laminar flame propagation velocity (SL) also significantly decreases was established. It is important when a certain concertation of ballast steam is achieved (the final percentage is determined by the design of the burner) there will be a sharp deterioration of combustion or even the formation of a flame will be impossible. The principal design of the hydrogen-oxygen-steam combustion chamber was proposed. The necessity of heating oxygen and hydrogen and the principle of determining the pressure under which it is advisable to supply oxygen and hydrogen to ensure the maximum intensification of mixing first of oxygen and steam, and then of the formed mixture and hydrogen, were substantiated.

The paper examines the features of biomass as a fuel and substantiates that for agrobiomass waste with a high content of alkali metal oxides and slag properties of ash, it is more appropriate to burn it in a dense bed in the form of pellets, which ensures a temperature at the exit from the furnace of no more than 900 °C, a low part of fly ash and low content of unburned carbon in it, and so eliminates the risk of smoldering deposits with their melting and slagging. Technical solutions are given and the experience is presented of gas and oil boilers of CHP plants of sugar factories reconstruction with their transfer to the burning of biomass and/or coal in a dense bed on a direct-flow grate with the replacement of the air heater with air-water heater, with the addition of stages of the boiling economizer to compensate for the decrease in the heat perception of the furnace screens, maintaining the overall height of the boiler and the plane of the boiler cell. The reconstruction of boilers according to the developed technical solutions is possible to perform in the interval between production seasons, its implementation on boilers BKZ-75 GMA of Radekhiv and Chortkiv sugar factories allowed to achieve acceptable technical, economic and environmental indicators and ensured payback due to the difference in commercial prices of gas and of agrobiomass pellets. It is proposed to replicate the positive experience in the creation of decentralized regulating thermal generation capacities of the country. Bibl. 30, Fig. 3, Tab. 4.

The presence of carbon dioxyl as a non-combustible admixture in the landfill biogas of solid household waste and the absorption of ambient air into the layer of landfill waste, and therefore its entry into the landfill gas, significantly reduces the concentration of methane in it, which affects the efficient operation of the gas piston engine of the power plant and the reduction of volumes electricity generation. With the use of computer modeling for the composition of biogas with an increased content of N2 and a reduced concentration of CH4 £ 32 %, calculations were made on the enrichment of biogas to concentrations of CH4 in it of 36–44 % due to the use of CO2 amine absorption technologies, in which the costs for the regeneration of the absorbent are compensated by the produced thermal energy of the gas piston engine of the power plant. The removal of carbon dioxide from biogas makes it possible to simultaneously increase the concentration of methane in it at the input to the heat engine, which contributes to the stable and efficient operation of the gas piston engine of the power plant and the increase in the amount of electricity generation as a result of energy utilization of landfill gas. The use of complex biogas utilization technology in the cogeneration mode allows obtaining not only electricity, but also heat, which can be used in absorption amine technologies for CO2 extraction from biogas and thus reducing carbon dioxide emissions into the atmosphere.

Published: October 2024

The principles of physical and mathematical modeling of inhomogeneous jet-pulsating fluidization in the self-oscillating mode considering the movement of solid granulated particles on the working surfaces of the gas distributing device are investigated. The research tasks include substantiating the method of interaction between the gas phase and granular solids to ensure the implementation of heterogeneous jet-pulsating fluidization in the self-oscillating mode, experimentally determining hydrodynamic parameters to minimize the risk of stagnant zones on the working surface of the gas distributing device and formulating principles for introducing flat gas jets into orthogonal planes through a gas distribution device. The physical model focuses on creating heterogeneous jet-pulsating fluidization which is based on the formation of heterogeneous porosity in the bed of solids within the apparatus chamber. The study highlights the importance of rationally organizing the interaction mode between the gas phase and solids to ensure active circulation of granular material between 3 main technological zones: humidification, active heat exchange and relaxation. This organization enables sufficient mass transfer along the height of the bed and getting a product with the desired properties. Implementing the proposed modeling principles in equipment development will allow increasing the heat utilization coefficient by more than 60 % and will facilitate the implementation of innovative technology. The research contributes to the development of fluidization technology and its application in granulation at temperatures exceeding the melting point of thermolabile components, ensuring efficient use of resources and energy, and enhancing the environmental safety of technological processes.

The article is devoted to the computational studies of the air-thermal state of office premises taking into account the effect of solar radiation coming through window openings. The study was conducted for a room with two windows using two heating devices installed under them. The air-temperature regime of premises in winter, characterized by the highest thermal energy consumption for heat supply, is considered. The study is based on the solution of a three-dimensional nonlinear heat transfer problem described by a system of equations of turbulent momentum and energy transfer. The k-e turbulence model is used to close this system. The results of numarical modeling of the physical situation under study are presented. The research data on the features of the air-thermal state of the premises under solar radiation conditions are given. The results of a comparative analysis of the air-temperature conditions of office premises corresponding to the solution of the specified heat exchange problems in the presence and absence of solar radiation are presented and the effects of solar radiation on the structure of the air flow and the thermal state of the premises are established. It is shown that in the presence of solar radiation, the air flow picture and the character of the temperature fields in the premises change significantly. In particular, in these conditions, the increase in the average temperature of the premises for the studied period is 2.5 °С. The possibility of a certain reduction of the load on the heating system in the presence of solar radiation is noted. Bibl. 17, Fig. 5.
