    Ion Exchange Membranes for Reverse Electrodialysis (red) Applications - Recent Developments
    (Amirkabir University of Technology - Membrane Processes Research Laboratory, 2021) Eti,M.; Othman,N.H.; Guler,E.; Kabay,N.
    The innovative membrane-based technology called reverse electrodialysis (RED) is capable of producing electrical power from the controlled mixing of two aqueous streams of different salinity. There has been tremendous progress so far in the development of RED process in terms of system development, spacer design, membranes properties and operational conditions optimization. Among those, characteristics of the ion exchange membranes are found to be the critical element affecting the performances of RED process. In this respect, a brief overview of the latest developments in ion exchange membranes were presented in this review, focussing on their properties and performances in RED applications. The recent developments of nanocomposite and ion selective membranes, particularly pore filling ion exchange membranes due to their high performances and inexpensive fabrication cost were also summarized. Shortly, fouling problem for the ion exchange membranes employed in the RED system was mentioned. © 2021 Amirkabir University of Technology - Membrane Processes Research Laboratory.

    Sağlık Profesyonellerinin Eğitiminde Simülasyona Dayalı Mesleklerarası Eğitim
    (2019) Şahan, Fatma Uslu; Terzioğlu, Füsun
    Mesleklerarası eğitim, sağlık profesyonellerinin lisans eğitiminde farklı meslek grupları arasındaki farklılıkları ve benzerlikleri daha iyi kavramalarına ve onların kendi profesyonel kimliklerini oluşturmalarına katkı sağlayan bir yaklaşımdır. Mesleklerarası eğitim dünyada sağlık alanında eğitim veren saygın üniversitelerineğitim müfredatlarına entegre edilmiştir. Türkiye’de ise henüz lisans müfredat programlarında yer almamaktadır. Ancak, Türkiye’de sağlık alanında eğitim alan öğrencilerin, mesleklerarası eğitim programları ile mesleki bilgi ve becerilerinin, yeterliliklerinin, diğer mesleklere olan farkındalıklarının arttırılarak ekip olarak çalışabilme becerisi kazanabilecekleri öngörülmektedir. Literatürde mesleklerarası eğitimin etkinliğinin arttırılması için yenilikçi bir yöntem olan simülasyonun kullanılması önerilmektedir. Simülasyona dayalı mesleklerarası eğitim, öğrencilerinteorik bilgileri ile uygulamaları arasındaki boşluğu gidermekte, iletişim becerilerini ve mesleklerarası ekip çalışması becerilerini geliştirmektedir. Ayrıca bu yaklaşım farklı meslekler arasında köprüler oluşturmakta, etkili bir ekip işbirliğini sağlayarak diğer mesleklerin rollerinin anlaşılmasına ve bilgi kazanımının sağlanmasına katkıda bulunmaktadır. Bu derlemede mesleklerarası eğitimin önemi, mesleklerarası eğitimde kazandırılması gereken yeterlilikler ve bu yeterliliklerin kazandırılmasında ve geliştirilmesinde yenilikçi bir yaklaşım olarak simülasyona dayalı mesleklerarası eğitim yönteminin kullanılmasına ilişkin yöntemler tartışılmıştır.

    (Turkish Neurosurgical Soc, 2021) Karaaslan, Burak; Celtikci, Emrah; Bulduk, Erkut Baha; Borcek, Alp Ozgun; Kurt, Gokhan; Kaymaz, Memduh; Emmez, Hakan
    AIM: To analyze the results of stereotactic radiosurgery in 295 patients with residual Grade I meningiomas located at parasellar region, petroclival region, cerebellopontine angle and parasagittal region. MATERIAL and METHODS: A total of 295 patients with Grade 1 residual Meningiomas (197 women, 98 men), who were treated by adjuvant radiosurgery in Gazi University Gamma Knife Center between 2004-2015 were analyzed. WHO Grade 2 and 3 meningiomas were not included in our study. Minimum radiological follow-up was 24 months. The median follow-up was 54 months. The tumor volume, location, treatment dose, morbidity, progression free survival and tumor control rate were analyzed. RESULTS: The median tumor volume was 5.2 cm(3) (0.04-39.7), median age was 50 (20-80), median dose was 14 Gy and tumor control rate was 94.5% (stationary in 85.0%, volume reduction in 9.5%). Increase in tumor volume was seen in 16 patients (5.5%) and re-operation was performed in 5 of them (1.6%). Stereotactic radiosurgery was performed again for 8 patients (2.7%).The location of the tumors was as follows: 39.3% parasellar region, 20% cerebellopontine angle, 13.6% petroclival and 27.1% was parasagittal, falcine or convexity. Major morbidities were detected in 6 (2%) patients. Minor morbidities were detected in 18 (6.1%) patients. CONCLUSION: Stereotactic radiosurgery is an effective and safe treatment modality for residual Grade I meningiomas.

    Journeying in Time and Space “through the Tall Heat That Slept”: Larkin's “the Whitsun Weddings”
    (Ovidius University, 2019) Elbir,N.B.
    This paper examines Philip Larkin's use of the metaphor of a train journey in his famous poem “The Whitsun Weddings” to transform time into space in such a way so as to enable the speaker to present a geographical and historical survey of the rural, urban and industrial landscape of mid-twentieth-century, post-war England, registering the social and cultural changes brought about by the process of modernization. The paper argues that the train journey functions as a metaphor for an imaginative journey, through time and space, that brings, in a characteristically discursive manner, Larkin's solitary and contemplative speaker from a state of detachment and superiority to one of heightened and thoughtful realization of the deeper implications of his perceptions as the train, and the poem near the final destination. In other words, the railway journey through the spatial and temporal metaphor of “the tall heat that slept” becomes a means of revealing and patterning the speaker's changing responses to the modern English landscape and English people. © 2019 Ovidius University.

    Frailty, Sarcopenia and Nutrition
    (Ankara Yildirim Beyazit University, 2024) Yesil,B.O.; Okur,İ.N.; Hızlı,Ş.
    Recently, the terms frailty and sarcopenia have been used frequently. Frailty, which occurs due to age-related physiological changes in multiple systems, is accepted as one of the geriatric syndromes. In frailty, negative energy balance, decreased strength, slowed walking speed, decreased grip strength, sarcopenia and involuntary weight loss can be seen. Frailty emerges as an indicator of biological age and correlates with the outcomes of biological age regardless of age, gender and comorbidities. Recent studies have begun to use the concept of frailty in children. Frailty in children is caused by a multi-system physiological impairment, including neurological, endocrine, immune and skeletal systems, which leads to a deterioration in quality of life. Frail children therefore require additional care and related services compared to children of the same age. Sarcopenia is defined as progressive loss in the musculoskeletal system. It has been determined that frailty and sarcopenia have many things in common in terms of their formation mechanisms, clinical consequences, treatment and prevention methods. Nutrition is closely related to both frailty and sarcopenia. Therefore, adequate energy and protein intake is extremely important in preventing malnutrition and loss of lean body mass. © 2024 Ankara Yildirim Beyazit University. All rights reserved.

    Reverse Electrodialysis for Salinity Gradient Power Generation: Challenges and Future Perspectives
    (Amirkabir University of Technology - Membrane Processes Research Laboratory, 2018) Güler,E.; Nijmeijer,K.
    Salinity gradient energy, which is also known as Blue energy, is a renewable energy form that can be extracted from the mixing of two solutions with different salinities. About 80% of the current global electricity demand could potentially be covered by this energy source. Among several energy extraction technologies, reverse electrodialysis (RED), using anion and cation exchange membranes for ionic transport that is converted into an electrical current at the electrodes, is most promising. This study provides a brief overview of recent advances in RED technology. Furthermore, it discusses future research directions and prospects to expand the true potential of this technology for power generation. Major emphasis should be on the development of task-specific membranes and stacks, the control of fouling and the design of new applications and hybrid processes. © 2018 MPRL. All rights reserved.

    Underground Structures, Rock Structures and Rock Mechanics From Ancient Era To the Modern Age;
    (TMMOB - Jeoloji Muhendisleri Odasi, 2017) Akiş,E.; Satici,Ö.
    Usage of underground space is an old habit for human beings since ancient era. Our ancestors have used caves as a shelter for protection from the wild life and nature, and they excavated caves to extract valuable minerals. They also used them as sanctuaries, tombs or for storage of goods. In addition, they built tunnels to be used as assault systems or to underpass fortifications during ancient warfare. Later on, tunnels were driven to supply water to the towns or to protect the towns from floods. They also built them for communication purposes. Though not knowing the exact time when they were first used, natural underground structures which have several interconnections were also built for underground dwelling purposes through the human history. In the following centuries, due to the need of transportation facilities, transportation tunnels were constructed where new excavation techniques were also used. Navigation canal tunnels, railway tunnels and road tunnels were constructed during that period. All these structures were mostly excavated in rocks. The first excavations were performed manually. Later on, fire technique had been used to excavate more easily. This was followed by the methods in which gunpowder, explosives and tunneling machinery were used. By some means or other, ancient civilizations had used fundamental principles of rock mechanics and applied these principles in the construction of the underground structures. Principles of rock mechanics are the sine qua non for all of these structures and facilities. In this review paper, the history and evaluation of rock mechanics will be given briefly and some examples of historical and monumental underground and rock structures will be presented. © 2017, TMMOB - Jeoloji Muhendisleri Odasi.

    Exile as a Spatial Metaphor in the Postcolonial Short Story
    (Ovidius University, 2019) Aksoy,N.B.
    The aim of this paper is to examine how the theme of exile embedded in spatial metaphors is taken up in the postcolonial short story. I will begin by contextualizing the postcolonial short story, its characteristic features and major themes. My argument will focus on in what way and why the theme of exile is an important issue in postcolonial literature and on the manifestations of the exile theme as a metaphor of space in the short story genre. The role of space will also be discussed within this context since it is firmly bound to the idea of postcolonialism in its literary, psychological and sociological sense. My argument will be illustrated through stories by representative postcolonial writers whose works display a distinctly “post-colonial” concern with the theme of exile. © 2019 Ovidius University.

    An Overview To Open Courseware: An Example of the Turkish Academy of Sciences;
    (2013) Umut,A.L.; Madran,O.
    This study reviews the open courseware approach, its benefits and examines open courseware platform of Turkish Academy of Sciences. This platform has 81 courses in 22 different categories. Our study analyzes usage data of the platform that is obtained from Google Analytics, which includes more than 300.000 visitors' transaction within a two-year period (January 15, 2011- January 15, 2013). The statistics showed that this platform had been visited 445,982 times by 315,830 people since January, 2011. It was observed that the development of the platform's content and promotion activities had a positive effect on the traffic of the site. On the other hand, it was seen that countrywide use of the platform was limited and some cities of Turkey did not use the platform at all. Turkey has a major potential in terms of its universities, students and academics' numbers. However, the advancements in the world related to the open courseware projects make Turkey's current efforts questionable. It is obvious that, Turkey must examine the past activities and make some critical plans for the future actions.
