Authors: GÜLER Birkut
Published: September 2023

Kanatla soğutma uygulamalarının endüstride uygulamalarını görebilmekteyiz. Motorlarda ve soğutma ihtiyacı olan yerlerde sıklıkla kullanılmaktadır. Mühendislik çalışmalarında, kanat uygulamalarının bir yüzeyden çevredeki havaya veya akışkana ısı transferini iyileştirmek önemli bir yer tutmaktadır Kanat kullanmanın amacı etkili yüzey alanını artırarak yüzeyden ısı transferini artırmaktır. Bununla birlikte kanadın bağlı olduğu alt taban da bir iletim direnci oluşturmaktadır. Bu nedenle kanatçık kullanmak her zaman ısı transferini artırmayabilir. Bu da kanat etkinliği ile ifade edilir. Bu çalışma, 450 W gücünde bir ısıtıcı kullanılarak alüminyum bir kanadın farklı hava üfleme konumlarında termal davranışını incelemek amacıyla gerçekleştirilmiştir. Çalışmada ısıtıcı üzerine alüminyum plaka ve yüzeyine termal macun uygulanmış ve ardından üzerine alüminyum kanatlar (finler) yerleştirilmiştir. Ayrıca, ısı transferinin nasıl etkilendiğini anlamak için farklı fan konumları denenmiştir. Fan, kanatlara dik, paralel ve 45 derece açıyla yerleştirilmiştir. Sonuçlar, fanın plakanın yüzeyiyle dik olarak yerleştirildiği durumda kanadın alt tutucusunun en düşük yüzey sıcaklığına sahip olduğunu göstermiştir. Bu sonuçlar, termal yönetimde fan konumunun kritik bir faktör olduğunu vurgulayarak ısı transferini optimize etmek için pratik uygulamalarda kullanılabilecek önemli bilgiler sunmaktadır. Bu tür bilimsel çalışmalar, enerji verimliliğini artırmak ve ısıl sistemlerin tasarımını geliştirmek isteyen endüstri ve mühendislik alanlarında uygulama potansiyeli taşımaktadır.

Energy plays an important role in the development of a country. Developing countries tend to lean towards the use of domestic renewable energy sources to reduce their dependency on foreign energy. However, when looking at the world as a whole, the share of fossil fuels in energy production is at high levels. Due to the rapid depletion of fossil fuels and their increasing costs, as well as the environmental damage they cause, electricity generation from cheaper and cleaner renewable energy sources is being targeted in the area where work will be done. Hybrid energy systems are used in conjunction with backup Unitss due to the variable nature of renewable energy sources such as wind and solar. In this study, a hybrid energy system with solar-wind-diesel generator-battery components was designed through HOMERPro software to meet the electricity demand of the closed prison in Burhaniye district of Balikesir. Simulations were carried out by applying 5 different battery scenarios in the hybrid energy system, and the optimum result was obtained. As a result, the effect of the batteries used on the system was examined, and the vanadium redox battery system with a high renewable energy ratio and the lowest Units energy cost was determined to be the most optimum.

Dünyada çevre sorunlarının artmasındaki en önemli nedenlerinden birisi olan hızlı nüfus artışı beraberinde fosil kökenli yakıtların fazla miktarda kullanılmasına ve hava kirliliği başta olmak üzere bir çok çevre sorununa neden olmaktadır. Fosil yakıtların insanlar tarafından bu kadar fazla kullanılması atmosferde ısıyı tutma kapasitesi yüksek olan sera gazlarının birikmesine dolayısıyla küresel ısınma ve iklim değişikliğine neden olmaktadır. Fosil yakıtların en çok kullanıldığı alanların başında ulaşım, ısınma ve enerji sektörleri gelmektedir. Bu çalışmada Zonguldak ili Kilimli ilçesindeki araç muayene istasyonuna ilave olarak yapılabilecek ikinci bir istasyonun Çaycuma, Gökçebey veya Devrek ilçesinde planlanması durumunda mevcut karbon salınımını ne oranla azaltabileceği araştırılmıştır. İngiltere Gıda ve Köy İşleri Departmanı (DEFRA) kriterlerine göre yapılan hesaplamalarda, mevcut istasyona bu ilçelerden gidilmesi durumunda 2738 ton eCO2.yıl-1 değeri hesaplanmış olup yeni istasyonun Devrek’te olması durumunda ve Çaycuma, Devrek ve Gökçebey deki araçların bu istasyona gideceği varsayıldığında 907,3 ton eCO2.yıl-1, Çaycuma’da olması durumunda 743,5 ton eCO2.yıl-1 ve Gökçebey’de olması durumunda ise 875 ton eCO2.yıl-1 seviyelerine düşmesi ön görülmektedir. Ulaşılan sonuçlardan yola çıkarak Zonguldak İli Çaycuma ilçesinde yeni bir muayene istasyonunun yaklaşık 2000 ton eCO2.yıl-1 karbon salınım miktarı azaltacağı hesaplanmıştır.

Published: September 2023

Sınır aşan bir akarsu olan Çoruh Nehri XIX. yüzyıldan günümüze uzanan süreçte büyük antropojenik müdahaleler ile karşı karşıya kalmıştır. Antropojen faaliyetler nedeniyle artan baskı delta kıyı çizgisinde değişime neden olmuş ve olmaya devam etmektedir. Baskı sadece morfolojiyi değiştirmemekte, ayı zamanda bölgedeki şehirleşmenin gelişim sürecinde de dikkate alınması gereken bir unsur olma özelliği taşır. Karadeniz’in güney doğusundaki önemli turizm merkezi olan Batum şehri, Çoruh Deltası üzerinde yer alır. Delta kıyısı boyunca gelişim gösteren Batum, kıyı erozyonundan doğrudan etkilenmektedir. Bu bağlamda şehre ait farklı fonksiyonlara sahip alanlar kıyı çizgisi değişiminin baskısı ile karşı karşıyadır. Bu çalışmada, Çoruh Deltası kıyı erozyonunun Uzaktan Algılama ve Coğrafi Bilgi Sistemleri yardımıyla belirlenerek aşınım ve birikim hızlarının (m/yıl) hesaplanması ve analiz edilmesi amaçlanmıştır. Bu sayede şehrin karşı karşıya olduğu risk net bir şekilde olarak ortaya çıkacaktır. Çalışmada 1984, 2000 ve 2020 yıllarına ait Landsat uydu görüntüleri kullanılmıştır. Uydu görüntülerinden itibaren NDWI (Normalized Difference Water Index) kullanılarak kıyı çizgileri üretilmiştir. Kıyı çizgisindeki değişim DSAS (Digital Shoreline Analysis System) kullanılarak araştırılmıştır. Çalışma sahasının I. grup olarak sınıflandırılan kesiminde aşınımın egemen olduğu ve aşınım hızının 2,37 m/yıl olduğu tespit edilmiştir. II. grup olarak sınıflandırılan kesiminde ise kıyı çizgisi ilerlemesi ve gerilemesinin bir arada gerçekleştiği belirlenmiştir. II. grupta aşınım hızının en yüksek 2,90 m/yıl, birikim hızının ise en yüksek 2,41 m/yıl olarak gerçekleştiği hesaplanmıştır. Çalışma bulguları özellikle Gonio plajının yer aldığı bölge ile Batum Uluslararası Havalimanı’nın kıyı erozyonuna bağlı olarak deniz ilerlemesi sorunuyla karşı karşıya olduğu savını desteklemektedir.
THE INFORMATIC IMAGE IN THE CONTEXT OF THE RELATIONSHIP OF THE ART
Authors: ÇADIRCI Orçun , HAZAR Eda
Published: September 2023

This text focuses on the dominant visual culture current policies, its relationship with the market and the partnership of this relationship with art. Information (visual) that indicates the actions of storing and disseminating information is a traditional form of activity that all cultures frequently resort to through art, from the first ages to the present. Because it is known that the functionality of the image is encountered even in cave painting in the history of civilization and the first data are these paintings built with communicative concern. Nevertheless, the real (purposeful) informatic image emerges in church murals in medieval Christian Europe. These (communicative) images, which emerge as an activity of the dominant system to convey itself, are informatic messages in terms of the meaning they are loaded. Accordingly, the image is always communicative between culture, market, system and individual. With this aspect, image is a type of information that enters the field of visual culture and turns into a kind of communication opportunity and it is clear that this has a transdisciplinary feature. As it can be understood, from the depths of civilization history to the present, visuality is a part of the activity of directing/managing the masses. It is also obvious that these possibilities have changed according to the visual culture instruments of the age. Like defined above, the individual interacting with the system according to the needs of the age is under the control of cultural relations networks. In this context, McLuhan pays attention in her text Medium is the Messages that the social structure came under the control of the media in the 1960s. Today, it can be said that this situation is beyond what the author claims and that the age of visual culture we live in has absorbed all the components from art to design, from artist to designer, from individual to society, into the system. Thus, a universe picture emerged in which almost all cultural productions turn into fictions that are blessed/glorified in terms of being art and/or design; in this universe built in the possibility of visual culture, visuality, which has a transdisciplinary character, has turned into a kind of communication opportunity.
THE CITY OF JERUSALEM ON THE ROUND CRUSADER MAPS
Authors: GELİR ÇELEBİ Azize
Published: September 2023

With the Crusaders taking Jerusalem in 1099, the city became a crucial centre for Christians. Since then, many pilgrims have come to visit the city. During the time when Jerusalem was under the rule of the Crusaders (1099-1187), many maps depicting the city were drawn. The general name of these maps, which show Jerusalem under the rule of the Crusaders, is Crusader Maps, and there are different types. However, what they have in common is that all of these maps are drawn very schematically. There are fourteen Crusader Maps of Jerusalem identified today. Although 11 of these maps is in the form of a round, it is thought that they were drawn or copied in the 13th and 14th centuries. Maps reflect the general characteristics of the period in which they were drawn. The article is based on the general features of these maps, known as the Crusader Maps, how the city of Jerusalem was depicted in the aforementioned period and the examination of the urban texture.

Authors: YILMAZ Şirin
Published: September 2023

In Turkey, new trends, which are alternatives to traditional art production in terms of method, material and subject, started to become visible as of the end of the 1970s. In the activities carried out under the leadership of the State Academy of Fine Arts and accompanied by the intellectual efforts of the Academy teachers based on philosophical discussions in the West, graduate students they had the opportunity to exhibit new and different productions and to be visible. In this generation, many artists who adopted new and different trends, beyond the classical painting and art education in the Academy curriculum; One of them was Gülsün Karamustafa. In addition to bringing local political and cultural elements to her artworks over the years, the artist has exhibited a diversity of materials and attitudes; It has continued her production process uninterruptedly by carrying it to the international level and has become one of the important names of Turkish Contemporary Art. Karamustafa's studies, which have developed around the issue of migration-based cultural hybridity, which emerged in the socio-political field of Turkey after 1980, have a quality that makes sociological readings possible in the context of the political and cultural structure of the country. Listening to the migration stories of her family since childhood; The political background of her family members and her contact with Istanbul, which had a very active sociological atmosphere during her youth, enables the artist to create the main themes in her artworks. The imagery shaped by the period and environment in which she lived, in the context of a cultural transformation-based objectivity, leads to the emergence of products in Karamustafa's artworks, in which subjects such as migration, cultural hybridity, identity, arabesque and kitsch are mostly discussed. The artist has produced a sincere and original art production by simultaneously transferring social issues that she blended with her personal history in line with multiple materials and artistic expression. This study aims to evaluate Karamustafa's work, her life and the social memory of the period she lived in, that period’s cultural structure, political readings and her testimony in the context of cultural hybridity.

Published: September 2023

Throughout our lives, as we communicate, we constantly learn new and different concepts. We then try to mentally concretize these concepts. If this process is carried out by drawing similarities with the knowledge we already possess, it progresses smoothly. However, if we attempt to associate them with concepts we are unfamiliar with, this process can be challenging and exhausting. This research was conducted to reveal the perceptions of undergraduate university students regarding the concept of "Landscape Architecture" through the use of metaphors. A total of 213 students from 14 different undergraduate departments participated in the study. The aim of the research is to uncover the perceptions of undergraduate university students regarding the profession of "Landscape Architecture" through metaphors. In this study, the phenomenological design, a qualitative research method, was used. Through a form containing questions for undergraduate students, they were asked to complete statements like "Landscape Architecture means ............ to me. Because .........." The content analysis technique was employed for analyzing the collected data. As a result of the research, participating university students generated 75 metaphors for the profession of "Landscape Architecture." These metaphors were grouped considering common attributes, yielding 9 main metaphors. The predominant perception of landscape architecture among university students from different departments emphasized themes of nature and design.

Published: September 2023

The effects of climate change have a significant impact on nearly every aspect of life on Earth, including human civilizations, the economy, and health. Data centers and other large-scale computing resources are among the human activities responsible for large greenhouse gas (BSG) emissions. Other human activities also contribute to this problem.   Although the growth of high-performance computing has allowed many important scientific breakthroughs to be achieved, the environmental impact of this progress cannot be underestimated. This paper describes a methodological framework for consistently and reliably estimating the carbon footprint of any computer business. The system can be used to calculate the carbon footprint of any computing task. A user can measure and report the carbon footprint of calculations using a newly created web tool called the Green algorithm (www.green-algorithms.org), which is freely available to the public. However, the tool is very simple to implement within computational procedures, as it uses very little information, does not interfere with pre-written code, and can accommodate a wide variety of hardware configurations. Taken as a whole, this research offers a simple, generalizable framework, as well as an accessible tool for measuring the carbon footprint of almost any computation.

THE NONLINEAR IMPACT OF RESEARCH AND DEVELOPMENT INVESTMENTS ON FIRM PERFORMANCE: A SIGMOID (S) CURVE APPROACH IN G20 COUNTRIES
Authors: ÖZER Gökhan , ÇAM İlhan , KOCAMAN Muhammet
Published: September 2023

The interaction between research and development (R&D) investments and firm performance has been extensively studied in the academic literature. However, these studies have produced different findings by proposing various models to explain the relationship between R&D and firm performance. The inconsistency in findings can be partly attributed to limitations in the use of traditional linear modeling methods that do not fully capture the complex dynamics of this relationship. Using data on 31,205 firms and 434,016 observations in G20 countries over the period 2000-2022, this paper considers the Sigmoid (S) curve model, which aims to reconcile the differences in the literature and provide a more comprehensive view of the R&D performance relationship. The findings reveal a non-linear relationship between R&D intensity and firm performance and the validity of the S-curve model. Specifically, the R&D-performance relationship shows a negative slope at low levels of R&D investment, a positive slope at medium levels, and a negative slope again at high levels. These results suggest that the impact of R&D investments on firm performance varies depending on the level of investment. Moreover, the study reveals that this 3-stage S-curve relationship is consistent for firms with low firm size and low leverage, and that such firms are particularly affected by an increase in R&D investment. Finally, the findings show that this relationship holds both between developed and developing countries and between countries following Anglo-Saxon and Continental European law. However, this relationship is more pronounced in Anglo-Saxon and developing countries than in Continental European and developed countries.

Cavernous-type malformations are venous lesions that occur in multiple locations throughout the body, and when present in the CNS, they have canonically been referred to as cavernomas, cavernous angiomas, and cerebral cavernous malformations. Herein all these lesions are referred to as "cavernous venous malformations" (CavVMs), which is congruent with the current International Society for the Study of Vascular Anomalies classification system. Even though histologically similar, depending on their location relative to the dura mater, these malformations can have different features. In Part 1 of this review, the authors discuss and review pertinent clinical knowledge with regard to CavVMs as influenced by anatomical location, starting with the dural and extradural malformations. They particularly emphasize dural CavVMs (including those in the cavernous sinus), orbital CavVMs, and spinal CavVMs. The genetic and histopathological features of CavVMs in these locations are reviewed, and commonalities in their presumed mechanisms of pathogenesis support the authors’ conceptualization of a spectrum of a single disease entity. Illustrative cases for each subtype are presented, and the pathophysiological and genetic features linking dural and extradural to intradural CavVMs are examined. A new classification is proposed to segregate CavVMs based on the location from which they arise, which guides their natural history and treatment.
Cavernous venous malformations in and around the central nervous system. Part 2: Intradural

Cavernous venous malformations (CavVMs) account for a spectrum of lesions with a shared pathogenesis. Their anatomical location dictates their clinical features and surgical treatment. Extradural and dura-based CavVMs were discussed in Part 1 of this review. In this part, intradural CavVMs are discussed, encompassing malformations growing within the intradural space without direct dural involvement. In addition to classic intra-axial CavVMs, cranial nerve CavVMs, intraventricular CavVMs, and intradural extramedullary spinal CavVMs are discussed in this group, given the similar natural history and specific management challenges. Herein the authors focus on critical clinical aspects of and surgical management of these malformations based on their location and discuss optimal surgical approaches at each of these anatomical locations with illustrative cases. The commonalities of the natural history and surgical management that are dictated by anatomical considerations lend to a new location-based taxonomy for classification of CavVMs.

OBJECTIVE

Encephaloceles of the lateral sphenoid sinus are rare. Originally believed to be due to defects in a patent lateral craniopharyngeal canal (Sternberg canal), they are now thought to originate more commonly from idiopathic intracranial hypertension, not unlike encephaloceles elsewhere in the skull base. A new classification of these encephaloceles was recently introduced, which divided them in relation to the foramen rotundum. Whether this classification can be applied to a larger cohort from multiple institutions and whether it might be useful in predicting outcome is unknown. Thus, the authors’ goal was to divide a multiinstitutional cohort of patients with lateral sphenoid encephaloceles into four subtypes to determine their incidence and any correlation with surgical outcome.

METHODS

A multicenter retrospective review of prospectively acquired databases was carried out across three institutions. Cases were categorized into one of four subtypes (type I, Sternberg canal; type II, medial to rotundum; type III, lateral to rotundum; and type IV, both medial and lateral with rotundum enlargement). Demographic and outcome metrics were collected. Kaplan-Meyer curves were used to determine the rate of recurrence after surgical repair.

RESULTS

A total of 49 patients (71% female) were included. The average BMI was 32.8. All encephaloceles fell within the classification scheme. Type III was the most common (71.4%), followed by type IV (16.3%), type II (10.2%), and type I (2%). Cases were repaired endonasally, via a transpterygoidal approach. Lumbar drains were placed in 78% of cases. A variety of materials was used for closure, with a nasoseptal flap used in 65%. After a mean follow-up of 47 months, there were 4 (8%) CSF leak recurrences, all in patients with type III or type IV leaks and all within 1 year of the first repair. Two leaks were fixed with ventriculoperitoneal shunt and reoperation, 1 with ventriculoperitoneal shunt only, and 1 with a lumbar drain only. Of 45 patients in whom detailed information was available, there were 12 (26.7%) with postoperative dry eye or facial numbness, with facial numbness occurring in type III or type IV defects only.

CONCLUSIONS

Endoscopic endonasal repair of lateral sphenoid wing encephaloceles is highly successful, but repair may lead to dry eye or facial numbness. True Sternberg (type I) leaks were uncommon. Failures and facial numbness occurred only in patients with type III and type IV leaks.

OBJECTIVE

Understanding the impact of the social determinants of health on the utilization of healthcare resources is an important step in eliminating inequalities. The goal of this study was to determine the role of social determinants of health in referral patterns, timing of consultation/intervention, and quality of life in children with Chiari malformation type I (CM-I).

METHODS

A retrospective study was conducted of children aged 0 to 18 years who underwent surgical treatment for CM-I at a single pediatric facility from 2015 to 2019. The variables included demographic and socioeconomic characteristics, referral patterns, timing, and quality of life data based on the Chiari Health Index for Pediatrics (CHIP).

RESULTS

The cohort consisted of 103 surgically treated CM-I patients. No differences were seen in race, sex, insurance, or household income when evaluating referral source (community, specialist, or emergency department) or when comparing patients with incidental versus symptomatic findings. In the evaluation of timing from initial evaluation to surgery, no statistical differences were seen between racial, sex, insurance status, or income groups. Children from households of lower median family income were significantly more likely to report pain at the time of consultation (pain group median [interquartile range] $46,660 [$41,004–$50,367] vs nonpain group $53,604 [$41,427–$59,828], p = 0.004). Those in the lower-income group also reported lower CHIP scores corresponding to increased symptomatology in the nonpain physical symptoms (p = 0.004) and psychosocial domains (p = 0.018).

CONCLUSIONS

There was no evidence of a difference in referral patterns or a delay in time from clinic presentation to surgery based on the traditional social determinants of health categories. Children from households in the lower-income group were associated with increased severity of pain and nonpain symptoms.

Indonesia sebagai salah satu negara maritim terbesar memiliki tujuan menjaga stabilitas keamanan maritim. Dalam mewujudkannya perlu adanya stabilitas kerja sama keamanan maritim. Pada prinsipnya, upaya Indonesia dalam menciptakan stabilitas keamanan maritim masih belum optimal. Masalah pencurian ikan oleh kapal asing masih marak terjadi. Faktor lingkungan strategis dan kerja sama pertahanan keamanan maritim menjadi aspek yang paling penting dalam mewujudkan poros maritim dunia. Cina menjadi negara dengan kekuatan armada laut maritim terbesar di Asia Pasifik dipandang perlu menjadi mitra strategis Indonesia dalam kerja sama pertahanan keamanan maritim. Diplomasi Angkatan Laut antara Indonesia dan Cina sudah terjalin sejak tahun 2005 dan terus mengalami pembaharuan. Kerja sama tersebut diperbaharui dalam kesepakatan Joint statement on strength comprehensive strategic partnership between the people's republic of China and the Republic of Indonesia in 2015 yang menghasilkan Navy to Navy Cooperation Talk (NTNCT) sebagai forum dialog kerja sama pertahanan angkatan laut. Penelitian ini bertujuan melihat implementasi dari NTNCT sebagai wujud kerja sama pertahanan yang telah dibentuk kedua negara dalam menjaga stabilitas keamanan maritim. Adapun metode yang digunakan peneliti adalah kualitatif deskriptif dan wawancara untuk menjelaskan lebih dalam mengenai diplomasi angkatan laut. Beberapa konsep seperti keamanan maritim, kerja sama pertahanan, dan kebijakan pertahanan sebagai alat negosiasi kepentingan kedua negara didalam forum NTNCT. Peneliti menemukan implementasi Navy to Navy Cooperation Talk sangat berkontribusi dalam bidang pertahanan keamanan maritim. Hal ini, dimanfaatkan Indonesia untuk dapat belajar dengan Cina sebagai armada laut kuat dalam menyiapkan sumber daya manusia Indonesia dalam bidang pertahanan menuju poros maritim dunia.
