Propolis: Harnessing Nature’s Hidden Treasure for Sustainable Agriculture
Authors: Bankova Vassya , Popova Milena
Published: November 2023

Recently, the search for sustainable and environmentally friendly agrochemicals from natural origin is steadily growing. Propolis, a resinous substance collected by honeybees, well known for its diverse biological activities, has attracted the attention of scientists and farmers with its agrochemical potential in the last years. This review article aims to delve into the fascinating world of propolis and its utilization in agriculture. Here, we provide a brief overview of propolis: its chemical composition and the bioactive substances responsible for its biological properties. The effectiveness of propolis in controlling common pests and diseases that affect crops, suppressing postharvest illnesses of fruits and vegetables, stimulating plant defenses and increasing stress resistance, is reviewed. Discussion of the challenges and future perspectives related to the integration of propolis in agriculture is also one of our objectives, including chemical variability, standardization and regulatory considerations. We also focused on the latest research trends and technological advances that promise to unlock the full potential of propolis as a sustainable agricultural tool.

Published: November 2023

In this article, we introduce a new subgradient extra-gradient algorithm to find the common element of a set of fixed points of a Bregman relatively nonexpansive mapping and the solution set of an equilibrium problem involving a Pseudomonotone and Bregman–Lipschitz-type bifunction in reflexive Banach spaces. The advantage of the algorithm is that it is run without prior knowledge of the Bregman–Lipschitz coefficients. Finally, two numerical experiments are reported to illustrate the efficiency of the proposed algorithm.

Authors: Montoya-Vallejo Carolina , Gil Posada Jorge Omar , Quintero-Díaz Juan Carlos
Published: November 2023

Microbial fuel cells are bio-electrochemical devices that enable the conversion of chemical energy into bioelectricity. In this manuscript, the use of biosurfactants (Tween 80 and surfactin) and the effect of coculturing E. coli and L. plantarum were used to investigate the generation of bioelectricity coming from an H-type microbial fuel cell. In this setup, E. coli acts as an electron donor while L. plantarum acts as an in situ biosurfactant producer. It was observed that the use of exogenous surfactants enhanced electricity production compared to conventional E. coli cultures. The utilization of Tween 80 and surfactin increased the power generation from 204 µW m−2 to 506 µW m−2 and 577 µW m−2, respectively. Furthermore, co-culturing E. coli and L. plantarum also resulted in a higher power output compared to pure cultures (132.8% more when compared to using E. coli alone and 68.1% more when compared to using L. plantarum alone). Due to the presence of surfactants, the internal resistance of the cell was reduced. The experimental evidence collected here clearly indicates that the production of endogenous surfactants, as well as the addition of exogenous surfactants, will enhance MFC electricity production.
The Effect of Monodentate Co-Ligands on the Properties of Pt(II) Complexes Bearing a Tridentate C^N*N-Luminophore

Published: November 2023

In this study, the insertion of different monodentate co-ligands on Pt(II) complexes bearing a monoanionic C^N*N luminophore as a tridentate chelator was achieved beyond the previously reported chlorido- ([PtCl(L)]) and cyanido-decorated ([PtCN(L)]) analogues. To investigate the impact of the auxiliary ligand on the photophysical properties, we introduced a neutral carbonyl-ligand and observed a lower photoluminescence quantum yield (ΦL) than with a cyanido moiety. However, the direct substitution of the chlorido co-ligand by a NO-related derivative was not successful. Interestingly, the attempted reduction of the successfully inserted nitrito-N-ligand in [PtNO2(L)] resulted in the oxidation of the Pt(II)-center to Pt(IV), as demonstrated by X-ray diffractometry. For comparison, the trifluoroacetato Pt(II) and chlorido Pt(IV) complexes ([PtTFA(L)] and [PtCl3(L)], respectively) were also synthesized. The photophysical characterization revealed similar photoluminescence profiles for all complexes, indicating a weak effect of the co-ligand on the excited state; in fact, all complexes display emission from metal-perturbed ligand-centered states (even the Pt(IV) species). Nonetheless, longer excited state lifetimes (τav) suggest a reduced thermally-activated radiationless deactivation via metal-centered states upon exchange of the chlorido units for other monodentate entities, yet without significantly improving the overall ΦL at room temperature. The irreversible oxidation waves (measured via cyclic voltammetry) mostly stem from the Pt(II)-center; the co-ligand-related drop of these potentials correlates with the increasing σ-donating capacities of the ancillary ligand. In summary, an enhanced π-acceptor capacity does not necessarily improve the ΦL and can even impair radiative rates by compromising the perturbative participation of the metal center on the emissive triplet state; in addition, strong σ-donor abilities improve the phosphorescence efficiencies by hampering the thermal population of dissociative electronic configurations related to the participation of antibonding d*-orbitals at the metal center.
Excited-State Dynamics of Bis(tetraethylammonium) Di-µ-bromo-dibromodicuprate(I) Thin Films
Authors: Gust Domenic , Scholz Mirko , Oum Kawon , Lenzer Thomas
Published: November 2023

Organic–inorganic halocuprates based on monovalent copper are promising luminescent compounds for optoelectronic applications; however, their relaxation processes in the excited electronic state are severely underexplored. In this contribution, we prepare thin films of bis(tetraethylammonium) di-µ-bromo-dibromodicuprate(I) [N(C2H5)4]2[Cu2Br4], abbreviated (TEA)2Cu2Br4, which features a “molecular salt” structure containing discrete [Cu2Br4]2− anions. This compound, which has an absorption peak at 283 nm, displays a blue, strongly Stokes-shifted emission with a peak at 467 nm. Transient photoluminescence (PL) experiments using broadband emission detection and time-correlated single-photon counting (TCSPC) both find an excited-state lifetime of 57 μs at 296 K. UV–Vis transient absorption experiments at 296 K covering time scales from femto- to microseconds provide evidence for the formation of the T1 state through intersystem crossing from S1 with a time constant of 184 ps. The triplet state subsequently decays to S0 predominantly by phosphorescence. In addition, the time constants for carrier–optical phonon scattering (1.8 ps) and acoustic phonon relaxation (8.3 ns and 465 ns) of (TEA)2Cu2Br4 are provided.
Walking Pilgrimage as Ritual for Ending Partnerships
Authors: Jenkins Kathleen E.
Published: November 2023

Scholarship in pilgrimage studies suggests that people use travel to sacred sites to mark life transitions such as moving into adulthood, retirement, the death of a loved one, or the ending of an intimate relationship. This research has also illustrated how walking pilgrimage can provide physical and symbolic structures for individual therapeutic and spiritual practice. However, pilgrimage scholars have not put the experience of ending long-term partnerships at the center of analysis, and family scholars have yet to explore how people might use extended walking pilgrimage as ritual when relationships end. Recent scholarship in pilgrimage studies has called for a more dynamic and inclusive approach that highlights the multiple and varied social forces at work in travel to and around sacred spaces. I draw from existing empirical studies, recent theory in pilgrimage studies, the literature addressing divorce rituals, and my qualitative document analysis of published narratives of extended walking after ending long-term partnerships to identify important sociological questions, methods, and perspectives for future research.
“But Angels Don’t Have Wings”: Art, Religion, and Michelangelo’s Last Judgment in Gilio’s Dialogue on the Errors and Abuses of Painters
Authors: Russell Anthony Presti
Published: November 2023

This article provides a close reading of Giovanni Andrea Gilio’s critique of Michelangelo’s Last Judgment as presented in the Dialogue on the Errors and Abuses of Painters (1564). The dialogue has generally been taken as reflecting the emerging Counter-Reformation concerns regarding the indecorousness of contemporary religious art, concerns that led to the censoring of the Last Judgment’s nudes in 1564 after the Council of Trent’s decree on sacred images. One frequent justification for ecclesiastical oversight over the production of religious art was that artists such as Michelangelo had prioritized their art over its religious contents and devotional aims. Though Gilio’s work has been read as confirming this view, this essay argues that the various opinions expressed during the animated exchanges in the dialogue yield a set of nuanced and often innovative interpretations of the Last Judgment that resist a reductive dichotomy between art and religion. Whether intentionally or not, the dialogue conveys that by the time of Michelangelo, and perhaps because of Michelangelo, the forms of art and the contents of religion could not be so easily distinguished from each other, largely because the artist’s subjectivity blurred the boundaries between the two.
HIStory against the World: Religion, Black Iconicity, and the Haunting Stretcher Photos of Michael Jackson and Tupac Shakur
Authors: Hill James Howard , White Bryson
Published: November 2023

This article examines how Michael Jackson’s 1984 stretcher photo and Tupac Shakur’s 1994 stretcher photo scrambles the disciplinary boundaries surrounding the academic study of religion. Drawing inspiration from Manning Marable’s concept of Blackwater, this study explores the complexities of black iconicity’s relationship to black suffering in the modern world. Through a critical analysis of the production and circulation of Jackson and Shakur’s respective stretcher photos, the following account highlights the disruptive force of black iconicity in modern society, unraveling its implications for religious meaning. By tarrying with these haunting photographic representations, this article prompts a reevaluation of the relation between (anti)blackness, visual culture, religion, and popular culture.
Predicting Tacit Coordination Success Using Electroencephalogram Trajectories: The Impact of Task Difficulty
Authors: Mizrahi Dor , Laufer Ilan , Zuckerman Inon
Published: November 2023

In this study, we aim to develop a machine learning model to predict the level of coordination between two players in tacit coordination games by analyzing the similarity of their spatial EEG features. We present an analysis, demonstrating the model’s sensitivity, which was assessed through three conventional measures (precision, recall, and f1 score) based on the EEG patterns. These measures are evaluated in relation to the coordination task difficulty, as determined by the coordination index (CI). Tacit coordination games are games in which two individuals are requested to select the same option out of a closed set without the ability to communicate. This study aims to examine the effect of the difficulty of a semantic coordination task on the ability to predict a successful coordination between two players based on the compatibility between their EEG signals. The difficulty of each of the coordination tasks was estimated based on the degree of dispersion of the different answers given by the players reflected by the CI. The classification of the spatial distance between each pair of individual brain patterns, analyzed using the random walk algorithm, was used to predict whether successful coordination occurred or not. The classification performance was obtained for each game individually, i.e., for each different complexity level, via recall and precision indices. The results showed that the classifier performance depended on the CI, that is, on the level of coordination difficulty. These results, along with possibilities for future research, are discussed.

The incidence of community-acquired pneumonia is an urgent problem of modern healthcare due to its high prevalence, which creates an additional burden on intensively working healthcare systems. An analysis of the epidemiological situation with this nosology over a ten-year period is relevant, since it will allow developing or adjusting measures to reduce the incidence and prevent community-acquired pneumonia in the Republic of Tatarstan. The purpose of this study — to study the dynamics and trends in the incidence of community acquired pneumonia in the population of the Republic of Tatarstan for the period 2012–2021. The study used data from official statistical information of the Office of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare in the Republic of Tatarstan, statistical reference books of the Center for Hygiene and Epidemiology in the Republic of Tatarstan for 2012–2021. The design of the study is a descriptive and evaluative epidemiological study as part of a retrospective epidemiological analysis of the incidence of CAP in the Republic of Tatarstan for 2012–2021. with an analysis of the long-term dynamics of the incidence of the population of the Republic of Tatarstan with the calculation of intensive incidence rates. When assessing the long-term dynamics of the incidence (2012–2021) of community-acquired pneumonia in the Republic of Tatarstan, a trend towards an increase in the incidence was revealed at an average rate of 27.4 ± 0.5 % per year (ρ = 0,748, р < 0,005) (2,3). The indicated trend rate increased the incidence of CAP over 10 years from 451.3 cases per 100 thousand us to 934.3 per 100 thousand us, or 2 times (2.3). The obtained results of assessing the incidence of community-acquired pneumonia over a ten-year period in the Republic of Tatarstan indicate the need for a detailed analysis of the monitoring system for patients with community-acquired pneumonia, as well as the need to improve it to increase the level of preventive measures.

pandemic of a new coronavirus infection (NCS) or COVID-19, announced by the World Health Organization in 2020, led to large-scale changes in the activities of all medical organizations in our country, which were forced to concentrate all their efforts to combat this infectious disease. There is an urgent need to convert most medical institutions into infectious diseases hospitals (IG) to treat patients with a new coronavirus infection. The developed federal and regional regulations for the work of medical organizations during a pandemic, including taking into account the experience of other countries, have made it possible to develop effective methods of combating infection and properly organize the work process. Studies have shown that the distribution of patient flows during hospitalization and the treatment process in the hospital can prevent excessive infection of medical workers. The working conditions of medical specialists of the infectious diseases hospital during this period corresponded to the harmful class 3 degree (class 3.3.). The leading harmful factor of the production environment and the most significant in terms of hygienic significance was the biological factor, which was represented by pathogenic microorganisms of groups II–IV. An analysis of the maps of a special assessment of working conditions (SUT) during this period showed that there was an underestimation of the class of working conditions according to the factors of the labor process — severity and tension, which were rated as within acceptable values (class 2), which clearly did not correspond to the true indicators. The survey showed that the medical workers of the hospital, working in a full set of personal protective equipment, experienced pronounced discomfort and pathological changes in the cardiovascular and respiratory systems by the end of the shift. Studies indicate the need for SATS during a pandemic, taking into account higher indicators of both the biological factor (extreme working conditions — class 4) and other production factors (severity, tension, microclimate).

Published: November 2023

Since the degradation of material properties and defects often occur in engineering structures due to fatigue loading, it is necessary to develop non-destructive testing methods to assess the safety of engineering structures. In the aerospace industry in particular, the demand for early crack detection to ensure the safety and durability of engineered structures is growing. The automated inspection of pipelines using non-destructive testing (NDT) is desirable because visual inspections are not always consistent. In addition, automated inspections reduce the cost of the inspection process and improve its quality. Since the identification of cracks in engineering materials is very valuable for understanding initial and slight changes in the mechanical properties of materials in complex working environments, numerical simulations of propagating Lamb waves in a cracked pipeline were performed to study their non-linear behavior. Finally, the shapes of all the signal responses can be used to identify the depth, length, shape and orientation of cracks. The elapsed time before signal responses are received varies as a function of the orientation of a crack.

Global Payment Systems: A Critical Review
Authors: N. Parmar Mr Nishit
Published: November 2023

The Banking system is known as the lifeblood and an important base of the economy. It plays a vital role in the economic development and GDP of the country. The Banking System across the globe has improved to a larger extent in the last two decades with the rapid digital wave, globalization, and privatization which encourages more competition resulting in a balanced ecosystem.The world of payments is going to be fundamentally transformed between now and then. It will be reshaped by technology and redefined by regulation, the emergence of new economic powers, and changes in the global currency landscape. Most importantly, payments will be refocused from a commoditized proposition to a strategic, value-adding solution; one that is offered with a greater focus on the broader commercial and transactional context within which payment (or a transfer of value) takes place. In all of this, commercial banks can remain key players, but only if they respond quickly enough and with compelling value propositions.

Contar historias para la vida en Patagonia, es abrir una historia contada por héroes del “progreso”, para dar voz y lugar a aquellas existencias monstruosas y fantasmagóricas que viven y mueren más allá de la relación que separa la cultura de la naturaleza.
El camino de la geopolítica crítica en América del Sur: entre la estructura y el individuo
Authors: Rascovan Alejandro
Published: November 2023

El artículo de Sara Koopman, publicado en 2011 en la revista Geoforum, ofrece una precisa muestra de los debates que atravesaron no solo la geopolítica como disciplina académica, sino también a amplios sectores de las sociedades civiles y políticas en Occidente. En su sitio web de la Universidad de Kent, la autora comienza describiéndose como feminista y geógrafa política. Esta descripción, sin duda, constituye un posicionamiento político que también se refleja en el artículo en cuestión.La década de 2010 estuvo marcada, entre otras cosas, por un aumento en las disputas políticas sobre corporalidades. Esto no solo surgió desde los movimientos feministas, como el que tuvo lugar en la Argentina y que llevó a la sanción de la Ley de Interrupción Voluntaria del Embarazo, sino también en movimientos como el Me Too y Black Lives Matter, con epicentro en Estados Unidos. Estos movimientos realizaron claras denuncias de situaciones de violencia experimentada desde la corporalidad, tanto en el colectivo de mujeres como en personas afrodescendientes.

Published: November 2023

O “deslocamento rotineiro” entre a cidade (rua) e o campo (roça) e não apenas o da roça para a rua intensificou o uso da motocicleta pelas famílias de produtores rurais, a qual vem tornando-se, cada vez, mais presente na paisagem dos pequenos munícipios de economia agrícola. O objetivo deste estudo foi compreender o uso da motocicleta por parte das famílias de produtores rurais de Minas Gerais, segundo estado com maior número de motocicletas no Brasil. Utilizou-se dados do levantamento de dados primários, obtidos por meio da aplicação de 605 questionários, em 11 das 12 mesorregiões do estado. Os resultados revelaram que a motocicleta foi caracterizada como viabilizando a manutenção da vida na “roça”. O uso da motocicleta foi percebido pelos produtores rurais como favorecendo a gestão da propriedade rural e o desenvolvimento das atividades produtivas na propriedade. Mesmo mediante a moradia na “rua”, a propriedade rural continuou a se mostrar como parte integrante da vida da família, sobretudo, para os produtores pouco tecnificados, com baixa renda agrícola, que buscavam na “rua” a possibilidade de combinar atividades agrícolas e não-agrícolas para a sua reprodução social

A Novel Deep Learning Approach to Malaria Disease Detection on Two Malaria Datasets
Authors: ÇETİNER İbrahim , ÇETİNER Halit
Published: November 2023

Malaria is a contagious febrile disease transmitted to humans by the bite of female mosquitoes. It is important to diagnose this disease in a short period of time. Finding the mathematically best numerical solution to a particular problem is the most important issue for most departments. In deep learning-based systems developed, the difference between the real data and the predicted result of the model is measured using loss functions. To minimize the error rate in the predictions during the training process of deep learning models, the weight values used in the model should be updated. This update process has a significant effect on the model prediction result. This article presents a new deep learning-based malaria detection method that will help diagnose malaria in a short time. A new 21-layer Convolutional Neural Network (CNN) model is designed and proposed to describe infected and uninfected thin red blood cell images. By using thin red blood cell sample images, 95% accuracy was achieved with Nadam and RMSprop optimization techniques. The results obtained show the efficiency of the proposed method according to each optimization algorithm.

Türkiye’nin kuzeybatısında yer alan Biga Yarımadası, epitermal çözeltilerle ilişkili gelişen metalik cevherlerin yanı sıra asit-sülfat tipte akışkanlardan türetilmiş kaolin yatakları ve alkali-klorür tipte akışkanlardan türetilmiş silika çökelleri bakımından oldukça zengindir. Biga civarındaki Hamamtepe Kuvars Ocağı ve çevresindeki sinter höyükleri Etili jeotermal sistemiyle ilişkili olarak gelişmiştir. Hamamtepe Ocağı’na ait kuvarsların paleo-mikrofaunasını belirlemek ve litofasiyeslerin oluşum ortamlarını tespit etmek amacıyla mineralojik ve petrografik incelemeler yapılmıştır. Bu çalışmalarla kuvars mineralleri yüzeyinde bakteriyel aktivite ile ilişkili olarak gelişmiş ağsal yapılar, hifler, biyofilm kalıntıları ve küresel diatom/polen? tespit edilmiştir. Hamamtepe ve çevresinde tespit edilen paleo-mikrofaunaya ait kalıntılar bölgede meydana gelmiş olan silika çökeliminde abiyotik şartlar yanında biyotik faaliyetlerinde etkili olduğunu ortaya koymuştur. Ayrıca, biyotik faaliyetlere bağlı silika çökelim ortamının proksimal aprona ait su çıkış kanallarının hemen yakınlarındaki yamaçlarda veya kanallarda termofilik canlılar tarafından alkali-klorür tipte nötr sularda, yaklaşık olarak 60-95 °C aralığında gerçekleştiği belirlenmiştir.

Bu çalışmada, WLAN ve WiMAX uygulamaları için elektriksel olarak frekansı ayarlanabilir yeni bir düzlemsel evrilmiş-F anten (DEFA) tasarımı önerilmektedir. 30 × 25 × 10 mm3 boyutlarındaki antenin ana radyatörü simetrik olmayan kıvrımlı şerit elemanlarından oluşmakta ve frekans cevabı bu elemanlar arasında optimum konumda kullanılan bir PIN diyotu aracılığıyla dinamik olarak ayarlanabilmektedir. Sayısal tasarımı Ansoft-HFSS ve CST Microwave Studio benzetim yazılımları aracılığıyla gerçekleştirilen antenin prototip üretimi de gerçeklenerek, diyotun açık/kapalı durumları için geri dönüş kaybı ölçümleri alınmıştır. Önerilen anten diyotun kesim durumunda WiMAX bandında tek bent rezonans gösterirken, iletim durumunda 2.4 ve 5.2 GHz WLAN bantlarında rezonansa gelmektedir. Ayrıca E ve H-düzlemleri için ilgili frekans bantlarında oldukça düzgün ışıma karakteristikleri sergileyen antenin mutlak kazanç değerleri 2-4 dBi arasındadır.

Ülkemiz, önemli fay hatlarının üzerinde bulunmaktadır. Çeşitli parametreler açısından yapısal davranışın irdelenmesi yapıların deprem güvenliği için önemlidir. Sıkça tercih edilen taşıyıcı sistem türlerinden olan çelik yapıların davranışı üzerinde dolgu duvar etkisi bu çalışmada incelenmiştir. Uygulamada, dolgu duvarlar genellikle düşey yük olarak analizlere dahil edilirken, modele katılmadıkları için özellikle yatay yük altında yapısal davranış üzerindeki etkileri göz ardı edilmektedir. Bilindiği üzere; dolgu duvarların sayısal modele katılıp katılmamasının yapıların davranışı üzerinde olan etkisinin araştırılması yapı güvenliği açısından da önemli bir durum arz etmektedir. Çalışmada incelenen sayısal modeller SAP2000 programında üç boyutlu olarak analiz edilmiştir. Eşdeğer deprem yükü yöntemi ile deprem etkisi altında yapısal davranış incelenmiş ve artırımsal eşdeğer deprem yükü yöntemi ile yapı performansı araştırılmıştır. Analizlerden elde edilen sonuçlar ışığında sayısal modelinde dolgu duvarların basınç çubuğu olarak dikkate alındığı durumda, dolgu duvarların yalnızca düşey yük olarak dikkate alındığı duruma göre periyot değerlerinin arttığı, tepe noktası deplasmanlarının azaldığı görülmüştür. Diğer taraftan, aynı incelemede basınç çubuğu olarak dolgu duvarın modele katıldığı durumda taban kesme kuvvetinin arttığı ve daha az deplasman ile plastik mafsallaşma noktasına ulaşıldığı sonucuna varılmıştır.
Robust Versions of the Lower and Upper Possibilistic Mean - Variance Models for the One Period or Two Periods Cases
Authors: GÖKTAŞ Furkan
Published: November 2023

It is easy to use possibility theory in modeling incomplete information. Robust optimization is an important tool when there is parameter uncertainty. Thus, in this study, we propose robust versions of the lower and upper possibilistic mean - variance (MV) models when there are multiple possibility distribution scenarios. Here, we use entropy as a diversification constraint. In addition, we reduce these robust versions to concave maximization problems. Furthermore, we generalize them for two periods portfolio selection problem by using fuzzy addition and multiplication. On the other hand, these generalizations are not concave maximization problems. Finally, we give an illustrative example by using different solvers in Gams modeling system.

Türkiye’de mimarlık eğitimi, teorik, uygulamalı ve seçmeli dersler olmak üzere üç ana gruptan oluşmaktadır. Mimari tasarım dersleri mimarlık programında önemli yer teşkil ederken, ikinci grupta tasarım derslerini destekleyen yapı dersleri yer almaktadır. Yapı dersleri, öğrencinin yapı, yapım sistemleri, yapı bileşenleri ve yapı elemanlarını öğrenebildiği bir eğitim sürecini içermektedir. Bu eğitim süreci, her öğrencinin eğitmenler tarafından verilen totaliter bilgi aktarımı ile iki ve üç boyutlu uygulamaları ürettiği kapsamlı bir uygulamalı derstir. Bir yapı dersinin çıktısı, ders kapsamındaki süreklilik ve verilen uygulamaların ısrarlı tekrarı ile bina yapım bilgisinin öğrenilmesidir. Bu çalışma, İzmir Yüksek Teknoloji Enstitüsü Mimarlık Bölümü’nde 1. Sınıf düzeyinde verilmekte olan Yapı Teknolojisi ve Bilimi I dersinin sürecini inceleyerek 2021 yılındaki öğrenci verileri üzerinden çizim ve maket performansını mimari yapı eğitimi bağlamında incelemeyi ve değerlendirmeyi amaçlamaktadır. Bu çalışmada öğrencilerin aldıkları notlar istatiksel olarak incelenmiş olup, bu sürecin belirlenen kriterler bazında değerlendirmesi yapılmıştır.

Published: November 2023

Artan nüfus, gelişen sanayi ve teknoloji, enerjiye olan talebi her geçen arttırmaktadır. Bununla beraber, küresel ısınma, iklim değişiklikleri ve sürdürülebilirlik gibi etkenler, ilgiyi yenilebilir enerjiye kaydırmaktadır. Ancak yenilebilir enerji sistemlerinin de düzensiz üretim rejimleri nedeniyle, elektrik şebekelerinde istenilen esneklik sağlanamamaktadır. Bu soruna çözüm olarak, yenilenebilir enerji sistemlerinde enerji depolama tesislerinin kurulması fikri ortaya çıkmıştır. Bu çalışmada, bir üniversite yerleşkesinin bir yıllık gerçek elektrik tüketim değerleri incelenmiş, bu yerleşkeye enerji depolamalı bir güneş enerji sisteminin (GES) kurulması durumundaki elektrik üretim ve tüketim değerleri analiz edilmiş, enerji depolama sistemi ile tepe yük tıraşlama yapılarak yük profilinin iyileştirilmesi gerçekleştirilmiştir. Günlük, haftalık, aylık ve yıllık enerji üretim-tüketim değerleri detaylı olarak incelenmiş, yaz ve kış dönemlerinde elektrik üretim ve tüketim profillerindeki değişim, yük tıraşlama ve yenilebilir enerji üretimi ile elektrik şebekesine olan katkılarla beraber, çevresel ve ekonomik etkiler de ele alınmıştır.
Doğu Roma İmparatorluğu’nda Hipodrom Kültürü
Authors: KOZAN Mert
Published: November 2023

Hipodromun inşası milattan sonra III. yüzyılın başlarında Roma İmparatoru Septimius Severus tarafından Roma sirki ve Yunan stadyumları taklit edilerek başlamıştır. Bu kurumlar, yani stadyumlar, sirk ve hipodromlar antik Romalılar ve Yunanlılar için büyük önem taşıyordu. Bunlar hem atletizm hem de eğlence amaçlıydı. Ancak büyük kalabalıkların toplandığı bu kurumlar, çoğu zaman başka türden sosyal ve siyasi faaliyetlere de sahne olmuştur. İmparator Constantinus törenlerde kullanılmak üzere bir hipodromla bağlantılı bir imparatorluk sarayı da dahil bir dizi anıtsal bina yaptırdı. Bu hipodrom törenlerin merkezinde yer alarak yeni başkentin önemini de ifade ediyordu. Aslında, Constantinopolis Hipodromu neredeyse 900 yıl boyunca şehrin siyasi ve sosyal hayatının merkezinde yer almıştır Yıkıldıktan sonra bile arenası şehrin ana meydanı haline geldi. Büyük bir kısmı yüzyıllar önce yok olmuş olsa da muhteşem Mısır dikilitaşı da dahil olmak üzere önemli izleri bugün hâlâ görülebilmektedir.

El cultivo de la papa Solanum tuberosum L. en Colombia es clave en la seguridad alimentaria de hogares campesinos. Este sistema productivo se ve afectado por factores bióticos y abióticos, destacándose plagas de insectos como el gusano blanco Premnotrypes vorax (Hustache, 1933) que afectan la calidad del tubérculo. En este sentido es importante la generación de estrategias de manejo sostenibles para estas limitantes. Se destaca que los cultivos barrera pueden obstaculizar el paso de los adultos de P. vorax a los cultivos de papa, siendo importante evaluar cultivos con este potencial. Para esto se estableció un experimento en Mosquera, Cundinamarca (Colombia), que consistió en liberar adultos de gusano blanco en estructuras de evaluación del desplazamiento de los individuos en cultivos de avena Avena sativa Linnaeus, 1753 y cilantro Coriandrum sativum Linnaeus, 1753. Usando modelos de regresión para datos de conteo (poisson, binomial negativo y cero inflado), se encontraron diferencias estadísticamente significativas (p < 0,05) de la implementación de los cultivos de avena y cilantro como barreras naturales para reducir la entrada de adultos de P. vorax.
