Authors: KARABULUT Koray , ALNAK Dogan Engin
Published: March 2023

Minyatürleşen enerji sistemleri ve yüksek güçlü elektronik aletler soğutma kapasitesi yüksek olan sistemlerin kullanımını gerektirmektedir. Çarpan jet-çapraz akıştan oluşan birleşik jet etkisi mikroçip elektronik elemanlarının soğutma performansını artırıcı bir etkiye sahiptir. Bu çalışmada, kanallarda bulunan sabit 1000 W/m2 ısı akılı küp ve oyuklu desenlerin su ve %0,02 hacimsel nanoparçacık konsantrasyonlu GO (Grafen Oksit)-Su nanoakışkanı kullanılarak birleşik jet akışı ile soğutulması sayısal olarak analiz edilmiştir. Sayısal çalışma, sürekli ve üç boyutlu olarak k-ε türbülans modelli Ansys-Fluent programının kullanılmasıyla gerçekleştirilmiştir. Nanoakışkanın termofiziksel özellikleri deneysel olarak elde edilmiştir. Literatürdeki çalışmalar da göz önüne alınarak kanal boyutlarına uygun olacak şekilde kanallara üçer adet desenli yüzey yerleştirilmiştir. Kanallara ayrıca jet girişinden itibaren D jet giriş çapı ölçüsünde sabit bir uzaklıkta (N) 90o açılı kanatçık eklenmiştir. Kanal yükseklikleri 3D ve 6D iken akışkanların Re sayısı aralığı 5000-9000’ dir. Çalışmadan elde edilen sonuçların doğruluğu ve kabul edilebilirliği deneysel araştırmalar sonucu elde edilen eşitlik kullanılarak kanıtlanmıştır. Çalışmanın sonuçları, kanallardaki her bir desen için ortalama Nu sayısı ve yüzey sıcaklığının değişimleri olarak su ve nanoakışkan için kanatçıksız ve kanatçıklı durumlarda karşılaştırmalı olarak incelenmiştir. Ayrıca, birleşik jet nanoakışkan akışının hız ve sıcaklık konturu dağılımları jet-desen arası etkileşimler de göz önüne alınarak farklı kanal yükseklikleri için sunulmuştur. Bununla birlikte, kanallardaki her üç desenli yüzeyin tümü için farklı Reynolds sayılarında performans değerlendirme sayıları (PEC) ve ortalama Nu sayısı (Num) ve yüzey sıcaklık değerleri (Tm) Re = 9000 için değerlendirilmiştir. Re = 9000 ve H = 3D için GO-Su nanoakışkanlı kanatçıklı birleşik jet akışlı kanalda su akışkanlı ve kanatçıksız kanala göre küp ve oyuklu desen yüzeyleri için Num değerinde sırasıyla %45,04 ve %37,11’ lik artışlar elde edilmiştir. Bununla birlikte, Re = 5000 değerinde ve H = 3D yükseklikli kanallarda su akışkanı için PEC sayısı değerlerinin sırasıyla küp ve oyuklu desenli yüzeylerde nanoakışkana göre %1,69 ve %1,74 daha fazla oldukları tespit edilmiştir.

Published: March 2023

Endüstriyel faaliyetler, zirai ve evsel atıklar sonucu atık sularda bazen eser miktarda bazen de yüksek konsantrasyonda metaller bulunmaktadır. Metaller sularda çözünmüş halde bulunarak ya da su dibinde toplanarak kimyasal kirliliğe ve de çevre kirliliğine neden olmakta ve canlı sağlığı için de tehdit oluşturmaktadır. Deri sanayinde fazla miktarda su kullanılmakta olup, oluşan atık sular yüksek oranda kirletici madde içermektedir. Deri işleme sonucu oluşan atık suyun arıtılmadan alıcı ortama verilmesi durumunda, temiz su kaynakları kirlenmekte ve kullanımı kısıtlanmaktadır. Bu nedenle atık sularının, çevreye deşarj edilmeden önce uygun tekniklerle bertaraf edilip zararlı etkisinin azaltılması ve/veya giderilmesi oldukça önemlidir. Atık sulardan ağır metallerin uzaklaştırılmasında fiziksel ve kimyasal yöntemler etkin olarak kullanılırken, özellikle son yıllarda biyolojik yöntemlerle giderim işlemi de yaygınlık kazanmıştır. Kirleticilerin mikroorganizmalar tarafından biyolojik olarak parçalanarak, çevreye daha az zararlı bileşiklere dönüştürülmesi biyolojik yöntemlerle uzaklaştırma işleminin temelini oluşturmaktadır. Bu derleme çalışmasında, endüstrinin birçok dalında etkin olarak kullanılan yüksek toksik özellikteki Cr(VI)’nın mikrobiyal yöntemler ile daha az toksik Cr(III)’e indirgenmesinin önemi vurgulanmaya çalışılmıştır.

Impact of Monetary Policy and its Transmission Mechanism in Sudan
Authors: Naeem Mahmoud Hamid Arabi , Arabi Khalafalla Ahmed Mohamed , El-Maeia Howida Adam
Published: March 2023

The current paper investigates the impact of monetary policy and its transmission mechanism in Sudan, using the structural vector autoregressive (SVAR) model utilizing monthly data from Jan 2000 to the end of 2021. The findings show that Sudan's monetary transmission mechanism for credit and exchange rate channels performs poorly due to the salient features of the Sudanese economy and the financial and banking sector. The policy implication arising from this finding is; the role of the conduct approach for monetary policy should be clearly defined. Moreover, it is necessary to restore the credibility and reliability of the Central Bank of Sudan (CBOS) for conducting monetary policy. Sudan's monetary and credit policies must rely on indirect instruments, and the exchange rate should be determined by the market. The banking sector should be subjected to a program of reform and recapitalization. Other financial institutions, such as insurance companies and pension funds, must play a greater role in the economy.

In view of the economic impact and the changes in life habits caused by the Covid-19 pandemic in Brazil, the main objective of this article refers to the application of the fundamentalist valuation method of companies, called discounted cash flow, during the beginning, the course and the end of the pandemic period. The company in question is Magazine Luiza SA, given the positive variation in the value of the company's shares during this interval, as well as the investments made in digital transformation and the consequent significant increase in sales. The methodology adopted consists of collecting data disclosed by the company itself and, through the application of FCFF, performing the company's evaluation during the years 2019 to 2022, which characterized the duration of the pandemic, in addition to performing a projection based on the analysis performed until the year 2028. The analysis obtained showed slow and steady growth in the pre-pandemic period, that the initial pandemic period, between the years 2019 and 2020 represented for Magazine Luiza, contrary to what is expected for a retail company, a period of accelerated growth, which can be associated with the investments made for the digital transformation. Moreover, the projection obtained indicates, for the company, an initial crisis in the post-pandemic period, given the current political-economic environment. However, it presents trends for a recovery followed by subsequent accelerated growth.

Published: March 2023

The role of B cells in skin inflammation highlights the versatility of B cells in their response to diverse immune stimuli perceived as external threats to the host. B cells play a vital role in the immune system’s ability to effectively respond to offenses to the healthy skin microenvironment, such as wounds, malignant tumors, vector (tick)-borne pathogens, and the development of red meat allergies after a tick bite. Select examples from the literature that illustrate the role of B cells in these disrupted states reviewed individually below, and highlight little overlap in the role B cells play in the different diseases. Future studies will need to continue to research the relatively newfound role of B cells in maintaining healthy skin.
Reinforcement Learning: Playing Tic-Tac-Toe

Published: March 2023

Machine learning constructs computer systems that develop through experience. Applications surround disciplines in daily life ranging from malware filtering to image recognition. Recent research has shifted towards maximizing efficiency in decision-making, creating algorithms that quickly and accurately process patterns to generate insight. This research focuses on reinforcement learning, a paradigm of machine learning that makes decisions through maximizing reward. Specifically, we use Q-learning – a model-free reinforcement learning algorithm – to assign scores for different decisions given the unique states of the problem. Widyantoro et al. (2009) have studied the effect of Q-learning on learning to play Tic-Tac-Toe. However, the study yielded a win/tie rate of less than 50 percent. We believe that does not represent an effective algorithm to exploit the benefits of Q-learning fully. In the same environment, this research aims to close the gaps in the effectiveness of Q-learning while minimizing human input. Data were processed by setting the epsilon value as 0.9 to ensure randomness, then consecutively decrease with a constant rate as possible states increase. The program played 300,000 games against its previous version, eventually securing a win/tie rate of approximately 90 percent. Future directions include improving the efficiency of Q-learning algorithms and applying the research in practical fields.

Authors: Machuca-Aguado Jesús , Carrero-García Belén , Rodríguez-Zarco Enrique
Published: March 2023

Descripción del caso: Varón de 68 años con un cuadro de síndrome constitucional secundario a un absceso en el psoas, que en el TAC se le diagnosticó incidentalmente una posible lesión neoplásica. En la cistoscopia se identifica una neoformación polipoide que se extirpa en su totalidad mediante resección transuretral, siendo diagnosticada de tumor de células granulares de vejiga.
 
Relevancia: El tumor de células granulares es una neoplasia poco frecuente, con tan solo 27 casos en vejiga descritos. Estas lesiones son mayoritariamente benignas, aunque han sido descritos casos de naturaleza maligna. Debido a su presentación de forma asintomática, existe un infradiagnóstico de estas lesiones, que se traduce en la falta de información clínica y terapéutica, sin la existencia de guías para su manejo.
 
Implicaciones clínicas: Es importante conocer las características clínicas e histológicas de esta patología porque su clínica puede ser similar a la de algunas neoplasias de la vejiga; también es importante conocer la entidad para llevar a cabo un correcto tratamiento, teniendo en cuenta su característica tendencia a la recurrencia.
 
Conclusión: A pesar de ser lesiones infrecuentes, debido a su tendencia a la recurrencia y a su posible naturaleza maligna es importante tenerlas en cuenta.

Deficiency of adenosine deaminase 2: a challenging differential diagnosis of polyarteritis nodosa
Authors: Hassanzadeh Shakiba , Bahadoram Mohammad , Mowla Karim
Published: March 2023

Deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive that was first described in 2014. It is a monogenic disease that is caused by loss-of-function variants in the ADA2 gene. DADA2 involves small- and medium-sized vessels and its clinical presentations include polyarteritis nodosa (PAN)-like features such as livedoid rash, early-onset stroke, hypogammaglobulinemia, hematological abnormalities, and systemic inflammation. Early diagnosis and treatment of DADA2 are crucial as the clinical features could be potentially life-threatening but might be treatable. The first-line treatment of choice in DADA2 is tumor necrosis factor (TNF)-inhibitors. We aimed to give an overview of the known pathophysiology, clinical presentations, diagnosis, and treatment of DADA2. A clearer knowledge of DADA2 may help to better diagnose, manage, and improve the clinical outcome of DADA2 patients. However, further studies are required to investigate the genotype-phenotype associations and exact pathophysiology of DADA2.
The Necessity of Collaborative Federalism for Oil and Gas Management in Iraq
Authors: Khorsheed Najmadeen
Published: March 2023

The distribution of power and wealth is a contentious issue of federalism in Iraq. It has caused major conflicts between the federal government and the Kurdistan Regional Government (KRG), especially over the management of oil and gas. This paper aims to clarify the nature of those disputes and their possible solution through Elazar’s theory of collaborative federalism. After presenting the principal elements of collaborative federalism, it provides eight rationales for adopting collaborative approach in Iraq. The rationales are mainly examined in the context of managing oil and gas between the central government and KRG. The paper then discusses some potential challenges for changing the nature of federalism in Iraq from competitive to collaborative.

INTEGRATION OF SPATIAL DATA REPRESENTING BUILDINGS BY DETERMINING THE DEGREE OF SIMILARITY
Authors: Ďuračiová Renata , Igondová Magdaléna
Published: March 2023

Spatial data integration is the process of combining heterogeneous data to make them compatible, maintain data accuracy and actuality, minimize redundancy, and avoid data conflicts. Identification of spatial objects is one of the most important tasks in spatial data integration. In this paper, we propose to use determination of the similarity measures for assessment of spatial object identification. The result is an implementation of the proposed procedure into the geographic information system. In the case study we update the ZBGIS® database by the data from the real estate cadastre system. The innovation of the presented method is that the proposed process and the new implemented software tools are based on determination of the similarity measures such as the Dice similarity index and the Jaccard similarity coefficient with its modification as the Tanimoto similarity coefficient.

IoT-Based System of Monitoring Realtime Air Quality with MQ135 and Automatic Chicken Feeding
Authors: Dani Sasmoko  , Reni Veliyanti  , Rozi Azwar Pradana
Published: March 2023

IoT technology is useful for chicken farming to control the condition of the farm concerning some problems such as odour, temperature fluctuations and feeding time system. This study used MQ135 to detect ammonia odour level, DHT11 to check room temperature, and RTC3231 to regulate feeding time. The data obtained from the sensor was sent by wemos to the fire base and MySQL to be read on android so that it can be monitored directly by the breeder. When the ammonia level is above normal it will turn on the odour fan. If  DHT11 reaches the value above 300C, it will turn on the cooling fan, and turn on the heating light when the temperature is below 250C. As RTC3231 sets the time at 07.00 and 14.00, the chicken feeder will automatically open to feed the chickens according to the time set. Table 1 and 2 show that the experiment obtained a value of 100% working well. This study succeeded in monitoring environmental conditions through Android and executing automatic feeding at the predetermined time. Thus, it can be concluded that the use of IoT technology for monitoring and feeding system automation  in chicken farms is highly recommended.
Coupling physics-informed neuronal networks with 3D scanning pulsed Doppler lidar
Authors: Schiefer Christian , Kauczok Sebastian , Töws Albert , Weipert Andre
Published: March 2023

Abstract. Physics-Informed neuronal networks (PINN) is a research field where a neuronal network is trained to solve an incorporated partial differential equation that describes some physical phenomenon. This work describes the coupling of the Navier Stokes (NS) equation with data from a 3D scanning pulsed Doppler lidar to reconstruct blanked sectors with radial velocities in a plan position indicator (PPI) scan. For the reconstruction, only the adjacent line of sight (LOS) measurements were used as input data for the neuronal network. Almost one year of collected lidar data were used to analyze the wind field sector reconstruction algorithm. The results show that the reconstruction of 35° azimuth sectors feature mean square errors of less than 1 m2/s2 and absolute errors of less than 2 m/s in 99 % and 98 %, respectively, of all cases. The runtime is about 0.1 minutes on average with commercial off-the-shelve CPU hardware. The reconstructed wind field of radial velocities can be used either to fill in sectors where the lidar is blocked e.g. by an obstacle or to extend the maximum operational range by measuring only a few lines-of-sight with increased pulse accumulation time. An example of a range extension PPI provided here demonstrates that the range can be extended to 25 km while maintaining the total recording time of 30 s as for the reference PPI scan featuring only a maximum range of approximately 12 km.
Selective inversion of rift basins in lithospheric-scale analogue experiments
Authors: Samsu Anindita , Gorczyk Weronika , Schmid Timothy Chris , Betts Peter Graham , Cruden Alexander Ramsay , Morton Eleanor , Amirpoorsaeed Fatemeh
Published: March 2023

Abstract. Basin inversion is commonly attributed to the reverse reactivation of normal basin-bounding faults. This association implies that basin uplift and inversion-related structures are mainly controlled by the frictional behaviour of pre-existing faults and associated damage zones. In this study, we use lithospheric-scale analogue experiments of orthogonal extension followed by shortening to explore how the flow behaviour of ductile layers underneath rift basins promote or suppress basin inversion. Our experiments show that the rheology of the ductile lower crust and lithospheric mantle, modulated by the imposed bulk strain rate, determine: (1) basin distribution in a wide rift setting and (2) strain accommodation by fault reactivation and basin uplift during subsequent shortening. When the ductile layers deformed uniformly during extension (i.e., stretching) and shortening (i.e., thickening), all of the basins were inverted. When viscous deformation was localised during extension (i.e., necking) and shortening (i.e., folding), only some basins – which were evenly spaced apart – were inverted. We interpret this selective basin inversion to be related to the superposition of crustal-scale and lithospheric-scale boudinage during the previous basin-forming extensional phase.
Refining patterns of melt with forward stratigraphic models on stable Pleistocene coastlines
Authors: Boyden Patrick , Stocchi Paolo , Rovere Alessio
Published: March 2023

Abstract. The warmest peak of the Last Interglacial (ca. 128–116 ka) is considered a process analogue, and is often studied to better understand the effects of a future warmer climate on the Earth's system. In particular, significant effort has been made to better constrain ice sheet contributions to peak Last Interglacial sea level through field observation of paleo relative sea level indicators. Along tropical coastal margins, these observations are predominantly based on fossil shallow coral reef sequences, also thanks to the possibility of gathering reliable U-series chronological constraints. However, the preservation of many Pleistocene reef sequences is often limited to a series of discrete relative sea-level positions within the interglacial, where corals suitable for dating were preserved. This in turn, limits our ability to understand the continuous evolution of paleo relative sea-level through an entire interglacial, also affecting the possibility to unravel the existence and pattern of sub-stadial sea level oscillations. While the interpretation of lithostratigraphic and geomorphologic properties is often used to overcome this hurdle, geological interpretation may present issues related to subjectivity when dealing with missing facies or incomplete sequences. In this study, we try to step back from a conventional approach generating a spectrum of synthetic Quaternary subtropical fringing reefs for a site in southwestern Madagascar (Indian Ocean). We use the DIONISOS forward (Beicip Franlab) stratigraphic model to build a fossil reef at this location. In each model run, we use distinct Greenland and Antarctica Ice Sheet melt scenarios produced by a coupled ANICE-SELEN glacial isostatic adjustment model. The resulting synthetic reef sequences are then used test these melt scenarios against the stratigraphic record. We propose that this sort of stratigraphic modelling may provide further quantitative control when interpreting Last Interglacial reef sequences.
Adjoint of GEOS-Chem model by supporting HEMCO emission inventories and MERRA-2 meteorological data
Authors: Tang Zhaojun , Chen Jiaqi , Yang Panpan , Jiang Zhe
Published: March 2023

Abstract. Adjoint of the GEOS-Chem model has been widely used to constrain the sources of various atmospheric pollutants. Here we provide an updated version (GC-Adjoint-HEMCO) of the adjoint of GEOS-Chem model to support the MERRA-2 meteorological data and Harmonized Emissions Component (HEMCO) emission inventories. State-of-the-art inventories, such as CEDS (Community Emissions Data System), MIX, NEI2011 (National Emissions Inventory), and GFED4 (Global Fire Emission Database), are supported in GC-Adjoint-HEMCO. We find good agreements in carbon monoxide (CO) emissions from various inventories, chemical sources and sinks, and surface and column CO concentrations between GC-Adjoint-HEMCO and GEOS-Chem (v12-8-1) forward simulations. Furthermore, observing system simulation experiments (OSSE) are employed to evaluate the performance of GC-Adjoint-HEMCO in 4D variational (4D-var) assimilations. We find underestimations by approximately 15 % in the a posteriori anthropogenic CO emissions over North America and Europe due to limited coverage of observations by smoothing the pseudo-CO observations with Measurement of Pollution in the Troposphere (MOPITT) averaging kernels. As an example application of GC-Adjoint-HEMCO, we constrain anthropogenic CO emissions in 2015 by assimilating MOPITT CO observations. The a posteriori anthropogenic CO emission estimates derived in this work match well with Jiang et al. (2017) in North America and Africa but are overestimated in Asia, South America and Australia, which could be associated with the different treatment of MOPITT CO observations over ocean grids and the large differences in CO chemical sources and sinks. The updated model developed in this work is a useful extension of the adjoint of GEOS-Chem model.

Displaced people from Afghanistan comprise the largest protracted refugee population in Asia and the second-largest refugee population in the world. For nearly 40 years, most Afghan refugees have been received in neighboring Iran and Pakistan. In Iran, they have been provided with such provisions as healthcare, education, housing, employment, food, visas, and continuing residence. However, many Afghan refugees face significant barriers in accessing services, particularly when it comes to undocumented persons. This study identifies the factors affecting homelessness among refugees, drawing on interviews with eight Afghan men. We explore a four key elements (4Es) construct for supporting the empowerment of refugee people in Iran through education, employment, economic, and emotional support. The study argues that the 4Es approach can alleviate homelessness among refugees.

Antimicrobial resistance is a global public health issue and one of the most serious threats to the mankind today. Some bacterial strains have acquired resistance to most antimicrobial drugs and, therefore, new antibacterial agents that would overcome resistant strains are needed. In 2017, the World Health Organization published a list of priority antimicrobial-resistant pathogens. Most of these agents are gram-negative bacteria. Due to their structure, the gram-negative bacteria are more resistant to antimicrobials than gram-positive bacteria and cause significant morbidity and mortality worldwide. The main resistance mechanisms are: restricted drug absorption, modification of the target attack, inactivation of the antimicrobial drug by production of hydrolyzing enzymes and active drug efflux. These mechanisms may be innate or acquired by microorganisms, and understanding those mechanisms may create new treatment options for infectious pathology and may contribute to the development of new antimicrobial drugs that counter the microbial attempts to become resistant.

Current studies show that the increase in the incidence of Chronic Kidney Disease cannot be fully explained only by risk factors well elucidated in the specialty literature, as knowing that oxidative stress is prevalent in Chronic Kidney Disease patients and is considered to be an important pathogenetic mechanism. Reactive oxygen species, which appear in excess as a result of ischemic, toxic or immune mediator changes, can negatively influence various pathological processes in renal pathology. These processes mainly refer to the pathogenesis of Chronic Kidney Disease or acute kidney injury. There are at least two pathophysiological mechanisms by which oxidative stress is formed in renal pathology, and then their damaging effects can cause, maintain or aggravate the cause of the condition. Following the initiation of inflammatory processes, the progression of renal damage is accelerated, with the eventual damage to all nephron structures as well as the interstitial space. The main sources of reactive oxygen species are mitochondria, but other cellular organelles may also be involved. Oxidant radicals produce oxidation of proteins, lipids, modification of nucleic acids with destruction of cell membranes, induction of apoptosis and lysis of kidney tissue. It is shown that free radicals are normally annihilated by superoxide dismutase – the antioxidant enzyme. There are several biomarkers that can be evaluated to detect oxidative stress and antioxidant status in patients with chronic kidney disease. Their determination in the context of a complex examination represents an informational support in the elucidation of pathogenetic mechanisms with the implementation of non-invasive early diagnosis methods. We reviewed the Chronic Kidney Disease literature to see if the guidelines and data are reliable enough to justify a particular approach.

Published: March 2023

The study shows that some of Dimitrie Cantemir’s works (Divan and Description of Moldavia) reached the Neamt monastery from Moldova between the 18th – the first half of the 19th century. Copies of the Divan ..., printed in Iasi in 1698, were part of the old library of the monastery, being read by monks in the Paisian and post-Pasian period (17631859). The Description of Moldavia was even more appreciated in Neamt, which, thanks to the efforts of the monks, saw the light of print in 1825, within the monastery’s printing house. Since a small part of the edition remained in Neamt, the most of it, thanks to the Neamt monks again, were sent to many ecclesiastical centers, libraries, and universities, in all the lands inhabited by Romanians, including Bessarabia.

”The moral and psychological atmosphere” in the student environment during the germination phase of the national renaissance Movement in the MSSR
Authors: Rotaru Liliana
Published: March 2023

The context created by the premises and evolution of the national revival Movement and the delayed restructuring of the Soviet higher education stimulated the civic activism and the involvement of the „easily inflammable collective” of students in the events taking place in the MSSR in the second half of the 80s. Students from higher education institutions of the MSSR initiated actions consistent with the general objectives of perestroika, glasnost and national reawakening even before 1988, only that their actions were small, often singular, and the most resonant were identified and promptly penalized by the “competent bodies”, who monitored the mood of the academic collectives with particular attention. Although they had a complex network of methods and instruments for monitoring the „moral atmosphere and psychology” of the students, towards the end of 1988, the party authorities lost control and the battle for the minds and spirits of the students, they demonstrating civic and political maturity in the events of November 1988.

Abstract:

When the Quran was reveled upon the Holy Prophet (S.A.W), the companion of the Holy Prophet (S.A.W) focused to serve it from various aspects. Some of them were known for expertise of its words while other was for its meanings and interpretation. This method was carried out for two hundred years, and every aspect of the sciences of the Holy Quran formed to be a separate science. One of them was Tafseer i.e. interpretation of the Holy Quran. A lot of scholars were known as “Mufassireen” i.e. the interpreters. One of them was Ibn-i-abi-Hathim who born in 240 AH and got knowledge from the shining scholars of his era and also known for his several well-known expertise and contributions toward Islamic Sciences. He written down a book named as Tafseer Ibn-i-Abi-Hathim. Wherein, he collected the narrative style of interpretation of the Holy Quran and so on his book occupied a great status amongst the interpretations with chain of narrators i.e. تفسیر بالماثور. As it is clear that a scholar at that time was to be known by a huge number and authenticity of his teachers he learned from. He has many teachers of Tafseer, from whom he got the knowledge of tafseer and narrated it in his tafseer. This number is very huge, but we have chosen some selected scholars from whom Ibn-i-Abi-Hathim narrated in his tafseer, to make them introduce to the readers. Furthermore, as it is a case study of a specific area amongst his all teachers, that is why, we’ve acquired descriptive method of research in this article. First we discussed their names in alphabetical order strengthened by their narrations from his tafseer. And at the end the conclusions of the research have been given. This will help the new scholars in sorting out such areas, and will make them know elaborate such kind of questionable areas.

Authors: AKİMCAN Hatice
Published: March 2023

Hemen her toplumda başkaları tarafından görülmeyeni erken tahlil edip öngören şahsiyetler yaşamıştır. Dinî, felsefî ve siyasî amaçları olan bu şahsiyetlerin Kırgız toplumunda da mevcut olduğu aşikârdır. Bu bilge şahsiyetlerin biri olan Kalıgul Bay Uulu Rus işgali döneminden hemen önce yaşamış, dönemin sosyo-kültürel özelliklerini şiirlerinde yansıtmaya çalışan şair olarak tanınmaktadır. Devrin değiştiği bir dönemde yaşayan şair Kırgız edebiyatındaki “zamane şiiri”nin ilk temsilcisi olarak bilinmektedir. Zamane şiirlerine “ahır zaman” şiirleri de denilmektedir. Bu şiir türünün ortaya çıkmasına Rus işgalinin giderek Türkistan’a yayılması neden olmuştur. Komşu Kazak, Tatarların başına gelen toplumsal felaketlerin kendi ulusu için de endişe teşkil ettiğinin farkında olan aydın şairler halkı bu konuda uyarmak istemişlerdir. Kalıgul'un “Akır Zaman” şiiri, Rusların bölgeyi işgal etmesiyle birlikte değişecek sosyal hayatı, geleneksel aile düzeninin bozulmasını, farklı dindeki, dildeki milletin halka tesirini bilgelik ile tasvir etmektedir. Kırgız toplumundaki dini ve ahlaki değerleri şiirlerinde konu edinen Kalıgul Bay Uulu’nun hayatına ve şiirlerindeki ahir zaman tasvirlerine kısaca değindikten sonra, din eğitimi ve etnopedagojik açıdan bu şiirlerin önemi üzerine durulacaktır.
Cylinder- and Coated-cylinder-systems as Multifunctional Metamaterials: An Effective Medium Description
Authors: Kafesaki Maria
Published: March 2023

Cylinder- and coated-cylinder-based metamaterials constitute one of the most appealing metamaterial categories, especially in high frequencies, i.e. THz to optical. The effective medium descriptions though employed for the analysis of such metamaterials show serious limitations, especially in the case of high-index dielectric cylinders or cylinders made of resonant materials, such as phonon-polariton or exciton-polariton materials. In this talk we will present an effective medium approach suitable for the analysis and description of cylinder-based metamaterials, of either simple or coated/multicoated cylinders. The approach is based on the well-known to the Solid State Physics community Coherent Potential Approximation (CPA) method, combined with a Transfer Matrix scheme for the case of multi-coated cylinders. We will demonstrate here the power of this approach in the case of polaritonic cylinder systems and in systems of graphene-made nanotubes. In both cases a rich metamaterial behavior has been observed, including frequency regions of engineerable negative permittivity, negative permeability, and in some cases negative refractive index and hyperbolic response.
