PdRuO
2 /PVP nanomaterial was synthesized using a straightforward method and characterized using advanced analytical methods such as TEM, XRD, XPS, elemental mapping and SEM. The synthesized PdRuO2 /PVP nanomaterial was used as an ionophore in potentiometric sensor electrodes and successfully adapted to Cr3+ ion detection in a large number of aqueous samples. Several experimental parameters of the PdRuO2 /PVP sensor such as potentiometric behavior, selectivity, repeatability, response time, pH, titration, and recovery in real samples were investigated. Potentiometric behavioral characteristics were performed in the concentration range 1 × 10−6 –1.0 × 10−1 M. The repeated experiments performed six times showed that there was no deviation in the measurements. The limit of detection of the PdRuO2 /PVP potentiometric sensor was very low with a value of 8.6 × 10−8 M. The potentiometric measurements showed that the synthesized PdRuO2 /PVP ionophore was highly effective in detecting Cr3+ in a wide pH range of 2.0–8.0 and was found to have a shelf life of over 1 year. As a result, the synthesized PdRuO2 /PVP electrode material was found to be highly selective, stable, and applicable for Cr3+ detection. [ABSTRACT FROM AUTHOR]- Published

In this study, hyaluronic and glycolic acids were adsorbed on Tutmaç clay. Clay brought from the village of Tutmaç in Guzelsu town of Gurpinar district in Van. The clay we obtained in the form of large particles was first sieved with a pore size of 0.038 mm (400 mesh). This ground clay was heated in an oven at 100 °C for 24 hours and stored in a desiccator. The clay sample, that is, 0.2 gr clay, was weighed 10 times and adsorbed for 10 minutes at room temperature with 1,2,3,4.5 ml of concentrated hyaluronic acid and glycolic acid for each 0.2 gr clay. The same operations were carried out for heat-treated clay. When the adsorption process came to equilibrium, the samples were filtered on filter paper and then washed with ionized water. The solid part was dried and the Differential Thermal Analysis (DTA), Thermogravimetric Analysis (TGA) and Scanning Electron Microscope (SEM) analyzes of these samples were performed, and the results were obtained by interpreting the analyzes in the central laboratory. In this study, studies were carried out on pure clay and clay treated with acids. As a result of the processes and thermal changes, it was observed that the amount of hyaluronic acid adsorbing was higher in the untreated clay, and it was concluded that these clay minerals can be used as a skin mask when suitable conditions are met. At the same time, it was concluded that the pore structure of the clay was deteriorated and it moved towards an irregular shape with the heat treatment of pure clay.

Şabende, XVIII. Yy. Klasik Türkmen edebiyatının önde gelen şahsiyetlerinden biridir. XVIII. Yy. Türkmenlerin sosyal ve kültürel hayatında önemli değişikliklerin yaşandığı dönemdir. Bu zamana kadar konargöçer bir yaşam tarzını benimseyen Türkmenler, bu asrın ortalarından itibaren yerleşik yaşama geçmeye başlar. Bununla beraber bu yy. Türkmen edebiyatında sözlü kültürde yaşayan destanların yazıya geçirildiği görülür. Başta Andalıp olmak üzere pek çok şair Türkmen bahşılarının repertuarında bulunan destanları kendi üslupları çerçevesinde yazılı eser halinde kaleme alır ve böylece avtrlu destan adı verilen bir tür ortaya çıkar. Şabende'nin yazmış olduğu `Gül-Bilbil` adlı eser de bu özelliktedir. Çalışmamızın birinci bölümünde Türkmenistan Tarihi ve Türkmen destancılık geleneği, Şabende'nin hayatı ve eserleri ile, Gül-Bilbil destanı üzerine yapılan çalışmalar hakkında bilgi verdik. Türk edebiyatında kaleme alınan Gül Bülbül temalı eserler hakkında da genel bilgi verdik. İkinci bölümde, Türkmen destanlarının yapısı ve türleri ile halk hikayesinin tanımı verildikten sonra yapısal özellikleri açıklanarak, Türkmen bahşılık geleneği hakkında bilgi verilmiştir. Üçüncü bölümde halk hikayesi epizot yapısı verilmiş ve bu yapı Anadolu sahası halk hikayelerinden örnekler verilerek ortaya koyulmuştur. Dördüncü bölümde, bir önceki bölümde ortaya konulan epizot yapısından hareketle motifler çıkarılmış, halk hikayesi örneklerinden faydalanılarak incelenmiştir. Metinler bölümünde Gül-Bilbil destanının Kiril harfli orijinal metninden Latin harflerine aktarımı ve sonrasında Türkiye Türkçesine aktarımı verilmiştir. Sonuç bölümünde, aşk konulu destanî anlatmaların Türkiye sahasında halk hikâyesi, Türkmenistan sahasında ise destan başlığı altında verildiğini ifade ettik. `Gül-Bilbil` hikayesinin epizot ve motif yapısı bakımından Türkiye sahası halk hikayeciliği geleneği ile büyük benzerlikler taşıdığını tespit ettik. Özellikle kahramanın soylu bir aileden gelişi, kahramanın ailesinin çocuksuzluk problemi ile karşı karşıya kalması, kahramanların rüya yolu ile birbirlerine aşık olmaları, kahramana ad verilmesi, kahramanın olağanüstü varlıklar ile mücadeleler gerçekleştirmesi, Hızır – pir gibi kutsal kişilerin kahramana yardımcı olması ve kahramanımızın sevdiğine kavuşup kendi yurduna zaferle dönmesi gibi unsurlar Türk destan/halk hikayesi geleneğinin genel yapısı çerçevesinde `Gül-Bilbil` hikayesinde de görülmüştür. Bu da bize Türkmenistan sahasına ait olan bu eserin Türk Dünyası edebiyatı geleneği bağlamında müşterek bir kültür evreninin eseri olduğu sonucunu göstermektedir. Anahtar Kelimeler: Şabende, Gül-Bilbil Destanı, Motif, Halk Hikâyesi, Epizot Şabende is one of the leading characters of Classical Turkmen Literature of XVIII. century. XVIII. century is the period when important changes have occurred in the social and cultural life of the Turkmens. The Turkmens who have adopted a migrant settler-lifestyle until this time, started to become sedentary from the middle of this century. However, it is seen that the epics in oral culture in Turkmen literature were put down on paper in this century. Many poets, especially Andalıp, write the epics in the repertoire of Turkmen bahşıs within the framework of their own style and thus a type which is called avtrlu epic comes in sight. The work 'Gül-Bilbil' written by Şabende also has this feature. In the first part of our study, we provided information about the history of Turkmenistan and the tradition of Turkmen epic, the life and works of Şabende and works on Gül-Bilbil epic. We also gave general information about the works themed Gül-Bilbil written in Turkish literature. In the second part, after we gave the description of structure and types of Turkmen epics and folk story, we explained the structural features and gave information about the tradition of Turkmen bahşı. In the third part, the folk story episode structure is given and this structure is presented by giving examples from the folk stories of Anatolian area. In the fourth part, motifs were extracted from the episode structure revealed in the previous part and examined by using the folk story examples. In the text part, the transfer of Gül-Bilbil epic from the original Cyrillic letters to Latin letters and then the transfer to Turkish in Turkey. In the conclusion part, we have stated that epic stories about love is given under the title of folk story in Turkey and under the title of epic in Turkmenistan area. We have determined that 'Gül-Bilbil' story has great similarities with folk story tradition in Turkey in terms of episode and motif. Especially the elements such as that the hero comes from a noble family, the hero's family is faced with the problem of not having children, the heroes fall in love with each other through the dream, naming the hero, the hero struggles with extraordinary living creatures, holy person such as Godsend-father help to the hero and the hero comes together with his/her lover and returns to homeland with victory, were also seen in the 'Gül-Bilbil' story within the general structure of the Turkish epic/folk story tradition. This shows us that this work which belongs to Turkmenistan area is the result of the work of common cultural universe in context of Turkish World Literature tradition. Key words: Şabende, Gül – Bilbil Epic, Motif, Folk Tale, Episode 352

İsteğe göre özelleştirilmiş, yenilikçi bir dokunsal algılayıcı tasarımı yapılmış ve üretilen algılayıcı kuvvet konumlandırması ve sertlik karakterizasyonu uygulamalarında kullanılmıştır. Algılayıcı olarak kullanılmış olan eleman piezoelektrik malzemedir ve algılayıcının temel birimidir. Piezoelektrik elemanı darbelerden korumak ve algılayıcıya esneklik kazandırmak amacıyla bu eleman silikon tabakalar arasına gömülmüştür. Algılayıcı üzerine uygulanan kuvvetler hassas ve doğru biçimde makine öğrenimi algoritmaları sayesinde konumlandırılmışlardır. Bunun yanısıra algılayıcı sertlik karakterizasyonunda kullanılmış ve farklı sertliklerdeki elemanlar makine öğrenimi algoritmaları kullanılarak sınıflandırılmışlardır. A customized novel tactile sensor has been designed and produced to be used in force localization and stiffness characterization applications. The main element in the sensor providing sensing mechanism is piezoelectric element. This element has been sandwiched between silicone layers to be protected from impacts. As for force localization, force applications on the sensor have attempted to be estimated sensitively and accurately. Also some probes with different stiffness properties have been tested with the sensor and these probes have been distinguished using some machine learning algorithms. 121

The chemical formula of tincal mineral used in this study is Na20-2B203-10H20. The tincal ore, one of the important boron minerals, is extracted around Eskişehir in Turkey. Herein, we investigated the kinetics of dissolution in different parameters such as concentration, particle size, solid / liquid ratio, mixing speed and reaction temperature in the ammonium acetate solution of tincal mineral. As a result, boric acid production obtained by dissolution of tincal mineral in amunium acetate solution increased with temperature increase. However, in the dissolution process, boric acid production was found to be reduced by the increase in particle size and solid-liquid ratio. [ABSTRACT FROM AUTHOR]

In this present work the removal of zinc from aqucous solution was studied via adsorbtion.Bardakçi clay (provided from region of Bardakçi-Van) was used as adsorbant in the experimental section. For the adsorption of zinc from aqueous solution upon Bardakçi clay, the effect of solution concentration, pH of the medium and reaction temperature were chosen as parameters. It was found that the adsorption of zinc upon clay suface increased with increasing solution conceniratieon and increasing reaction temperature, and the adsorpton İncreased with increasing pH up to 5.5 then decreased a little level at pH:8, and then it was determined that the adsorptilon was İncreased again at pH:11., Bu çalışmada çinkonun sulu çözeltiden adsorpsiyon yoluyla uzaklaştırılması incelendi. Deneyselçalışmalarda Van ili Bardakçı yöresinin kili adsorbent olarak kullanıldı. Sulu çözeltiden çinkonun Bardakçı kili üzerine çinkonun sulu çözeltiden adsorpsiyonu için çözelti konsantrasyonu, ortamın pH' sı ve sıcaklık parametre olarak seçildi. Elde edilen sonuçlar değerlendirildiğinde adsorplanan madde miktarının artan çözelti konsantrasyonu ve reaksiyon sıcaklığının artmasıyla arttığı tespit edildi. Ayrıca adsorplanan madde miktarı pH 5.5' kadar arttığı, pH 8' de ise adsorplanan madde miktarında çok az bir miktarda azalma olduğu görüldü ve pH 11'de adsorplanan madde miktarının yeniden arttığı belirlendi.

Objective: The objective of this study is to evaluate air pollution in Aydın city between 1997-2004. Method: In this cross sectional study, the levels of particulates and sulfur dioxide in the city of Aydın have been examined between 1997 and 2004. The data have been acquired from the Environmental Health Division of the Health Directorate of Aydın province. Samples were continuously measured by a semi automatic sulphur dioxide and exhaust sampler (Burch-Bulap 201-8, 87036) at the Public Health Laboratory. Measurements of 14 different areas of the city were made twice daily: in the morning (08.00-09.00) and in the evening (16.00-17.00). Montly and yearly comparisons were made using the average values of measurements taken between 1997-2003 with the standards of the Air Quality Protection Regulations. Findings:During the seven year period of monitorization, differences in levels of sulfur dioxide, particulatesand the level of air pollution were insignificant (for the level of sulphur dioxide and particulates, p=0,526, p=0,822 respectively). The seven year average of the level of sulfur dioxide was 41,26±24,86 μgr/m3; while the particulate matter was 27,66±16,23 μgr/m3. In winter months, especially January air pollution levels were the highest (p=0,000). Conclusion: The air pollution measurements do not exceed the Air Quality Protection Regulation, suggestedlong/short term standards. As for the levels of sulphur dioxide and particulates, there has been no change between the years 1997-2003. The organized projects of the Environmental Health Division of the Health Directorate of Aydın Province has played a significant role concerning these results. Even though the limits have not been exceeded, due to meterological conditions during the winter months, the air pollution parameters show an obvious increase in the air pollution. Because of several regulatory changes, air measurements have not been obtained for the last year, and so no current data are available. If adequate air pollution control measures are not taken, there may be a rise in air pollution parameters. Especially during the winter months, the air pollution levels should be continually monitored as sudden increases may occur., Amaç:Çalışmanın amacı, 1997-2004 yılları arasında Aydın ili kent merkezindeki hava kirliliğinideğerlendirmektir.Yöntem:Bu kesitsel çalışmada, 1997-2004 yılları arasındaAydın merkezindeki kükürtdioksit ve partikül maddedüzeyleri incelenmiştir. Veriler, Aydın İl Sağlık Müdürlüğü Çevre Sağlığı Şubesi'nden elde edilmiştir. Ölçümlersürekli örnekleme yapan yarı otomatik kükürtdioksit ve duman ölçer cihazı (Burch-Bulap 201-8, 87036) ile HalkSağlığı Laboratuarınca yapılmıştır. Ölçümler kent merkezindeki 14 farklı bölgeden, sabah (08.00-09.00) veakşam (16.00-17.00) olmak üzere iki kez yapılmıştır. 1997-2003 yılları arasında elde edilen ölçümlerin ortalamadeğerleri aylara/yıllara göre karşılaştırılmıştır. Ölçümler Hava Kalitesinin Korunması Yönetmeliği değerleri ilekarşılaştırılmıştır.Bulgular:Yedi yıllık süreçte kükürtdioksit ve partikül madde değerleri incelendiğinde yıllara göre hava kirliliğidüzeylerinde herhangi bir farklılık tespit edilmemiştir (kükürtdioksit ve partikül madde için sırasıyla: p=0,526,p=0,822). Yedi yıllık ortalama kükürtdioksit düzeyi 41,26±24,86 μgr/m3μgr/m3olarak tespit edilmiştir. Aylara göre hava kirliliği düzeyleri karşılaştırıldığında en yüksek değerler kışaylarında, özellikle Ocak ayındadır (p=0,000).Sonuç:Aydın'da hava kirliliği ölçümleri, Hava Kalitesinin Korunması Yönetmeliği'nin öngördüğü uzun/kısavadeli sınır değerleri aşmamıştır. 1997-2003 yılları arasında kükürtdioksit ve partikül madde değerleribakımından yıllara göre herhangi bir farklılık tespit edilmemiştir. Bunda, Sağlık Müdürlüğü Çevre SağlıkŞubesinin düzenli çalışmasının rolü büyüktür. Her ne kadar sınır değerler aşılmasa da kış aylarında meteorolojikkoşullar nedeniyle hava kirliliği parametrelerinde belirgin artışlar saptanmıştır. Mevzuat değişikliği nedeniyleson bir yıldır ölçüm yapılamamakta, hava kirliliği verilerine ulaşılamamaktadır. Kirlilik kontrolü ile ilgili olarakalınan önlemler yeterince uygulanmazsa, hava kirliliği parametrelerinde yükselmeler görülebilir. Özellikle kışaylarında kirlilik düzeylerinde ani yükselmeler olabileceği için ölçüm ve izlemlerin sürekli yapılmasıgerekmektedir

Girişim probleminin çalışıldığı geleneksel endüstrinin bir örneği tekstil endüstrisidir ki; burada bir işçi, kumaş dokuyan bir çok dokuma tezgahına servis vermektedir. Operatörün görevi dokuma tezgahında herhangi bir sebeple iplik kopuşu veya duruş meydana geldiği zaman; bu duruşu gidermek ve dokuma tezgahım sürekli çalışır vaziyette tutmaktır. Zaman zaman bir çok dokuma tezgahı aynı anda durabilir. Bu durumda bir operatör, bir anda sadece biri ile ilgilenebildiği için girişime sebebiyet vermektedir. Temel makine girişim problemi (ekonomik üretim ve diğer düşüncelere dayalı ) bir operatöre verilebilecek uygun makine sayışma karar vermektir. Bu çalışmada, tekstil sanayindeki dokuma işletmelerinde oluşan girişim zamanı ve bir operatöre tahsis edilecek makine sayısının doğru tesbit edilmesinde kullanılacak bir simülasyon programı geliştirilmiştir. Geliştirilen bilgisayar programı, her işletmenin kendi şartlarına göre uygulanabilmektedir. Ayrıca, farklı kuyruk disiplinleri ile servis verilmesinin sistem performans değişkenleri üzerindeki etkileri incelenmiş ve minumum girişim zamanım sağlayan kuyruk disiplini belirlenmiştir. Anahtar Kelimeler : Makine Girişimi Problemi, Simülasyon, Operatör Kullanımı An example of a traditional industry in which interference problem has been studied is the textile industry, where one operator attends several looms that are weaving farbric. The operator repairs machines when a yarn break or machine failure occurs and maintains looms in machinery position. Occasionally, multiple looms may stop simultaneously because an operator can attend only one at a time, and interference results. The basic machine interference problem is to decide (on the basis of economics of production, or other considerations) the appropriate number of machines to be assign to an operator. In this study, a simulation programme is developed to determine machine interference time and the appropriate number of machines to assign to an operator in weaving plants in the textile industry. Developed computer programme can be applied for any weaving plant with its conditions. Moreover, the effects of the different queue diciplines on system performance variables is analyzed. Subsequently, the queue dicipline that gives the minimum machine interference time is determined. Key Words: Machine Interference Problem, Simulation, Operator Utilization 107

VI ÖZ Bu çalışmada Van'ın Bardakçı ve Yumrutepe (Turna sın) köylerinden alınan iki kil numunesi ile Eskişehir Lüle tası belli miktarlarda alınarak herbiri ikişer kısma ayrıl dı. Bunlardan birinci kısımlar ayrı ayrı palmitik asit ile öteki kısımlar ise stearik asitle karıştırılarak 100 `C sıcaklıkta ısıtıldı. Böylece asitlerin killere adsorpsiyonu sağlandı. Elde edilen örnekler n-Hegzanla yıkandıktan sonra herbirinin DTA, TGA eğrileri ve İR spektrumları alınarak değerlendirildi. In this study, two clay samples taken from Van Bardakçı and Yumrutepe villages, and an Eskişehir rock sample (sepiolite) were divided into two groups. The first group was treated with palmitic acid and the other one was mixed with stearic acid and both groups were heated at 100 `C. Thus the adsorbtion of acids into clays were assured. 74

ÖZET Ağustos 1984 ile Nisan 1986 tarihleri arasında Uludağ Üni versitesi Tıp Fakültesi Üroloji Anabilim Dalı'nda değişici epitel hücreli mesane kanserli 40, mesane dışı urogenital sistem maligni- teli 24 ve malignite dışı urogenital sistem hastalığı saptanan 51, toplam 115 olgu R.F. aktivitesi yönünden değerlendirildi. Tüm olgu larda Latex lam aglütinasyon yöntemi ile R.F. arandı. Ayrıca R.F. olumlu bulunan mesane kanseri olgularında titrasyon çalışması ya pıldı. R.F. aktivitesinin olumluluk oranı mesane kanseri olgula rında yüksek, diğer urogenital sistem hastalıklarında düşük oran larda bulundu. R.F. aktivitesinin olumluluk oranı, mesane kanserinin ma lignite derecesiyle ilişkiliydi. R.F. aktivitesi olumlu bulunan olgularla, olumsuz bulunan olguların birinci, ikinci veya üçüncü sistoskopik kontrollerinde saptanan yineleme oranları istatistiki olarak karşılaştırıldığında R.F.'nin prognostik bir değer olarak önemi vurgulandı. 33

WOS: 000324332400013, The purpose of this study is to investigate the effect of computer-assisted learning integrated with metacognitive prompts on elementary students' affective skills on the subject of electricity. The researchers developed educational software to enable students to easily and comprehensively learn the concepts in the subject of electricity. A case study method was used. Eighteen students from the seventh grade (12-13 years) participated in the study. Students' views on their performances while using educational software and the impact of the software on their affective skills towards the subject of electricity were examined. Data were collected by open-ended questions in the educational software. According to the research results, there were students who had negative attitudes and perceptions before starting to learn about the subject of electricity. Interactive activities, animations, and visual experiments in the educational software were effective in overcoming the students' negative attitudes and perceptions about the subject. Besides, students who assessed their own performances during the learning process believed themselves to be more successful over time. In the light of the research results, some suggestions are made for future studies., TUBITAK [106K268], This study was supported by TUBITAK (Project#106K268).

WOS: 000310955500032, The main purpose of this study is to explore preservice science teachers' mental models of science teaching. Additionally it is investigated whether there is a significant correlation between their gender and grade levels in terms of mental models. The sample of this study composed of 300 (111 males and 189 females) pre-service science teachers from Turkey. As a data collection instrument "Draw a Science Teacher Test-Checklist (DASTT-C)" was used. The test was made up two sections. In the first section of the DASTT-C, the pre-service science teachers were asked to "Draw a picture of yourself as a science teacher". In the second section, they were asked to give answers to the questions "What is the science teacher doing? and what are the students doing?" regarding their drawings. The data was the coded according to the rubric and analyzed with SPSS. The results of study showed that pre-service science teachers' mental models of science teaching were in the categories of conceptual teaching (61%), exploratory or inquiry/constructivist teaching (22%), and explicit/didactic teaching (17%). There was no significant difference between male and female but there was significant difference between the grade levels in favour of senior levels with regard to their mental models of science teaching. In the light of the results, some suggestions were made for further studies.
