Suture materials are natural or synthetic biomaterials used to close tissues together. After surgical procedures in the mouth, the surgical site and the sutures are physically affected by many different factors. This study was conducted to evaluate the effects of frequently consumed beverages on the tensile strength of monofilament PGLA (polyglycolide-co-l-lactide) and multi-filament PGCL (polyglycolide-co-caprolactone) absorbable sutures. In particular, PGLA and PGCL absorbable sutures, which are frequently used in oral surgery, were used to evaluate the change in the strength of suture materials. The suture materials were soaked in tea, coffee, and cola drinks five times a day for 5 min each and the rest of the time in artificial saliva. All suture materials were aged via thermal cycling. Tensile strengths were tested at 0, 3, 7, and 14 days. Mixed ANOVA (four replicates: within-group comparison and two factors: between-group comparison) was performed to evaluate the effects of groups and time on the tension levels of the Tekmon and Vicryl suture materials. Analysis of Variance was used for the within- and between-group comparisons, with the Bonferroni corrected t-test for multiple comparisons. For the PGCL suture material, there were significant decreases in tension levels in artificial saliva, tea, coffee, and cola at time T3 compared to T0, T1, and T2, and at T1 and T2 compared to T0. For the PGLA suture material, there were significant decreases in tension levels in artificial saliva, tea, coffee, and cola at time T3 compared to T0, T1, and T2. There was also a significant decrease in tension level at time T2 in cola compared to T0. The present study demonstrates that beverages significantly decrease the strength of suture materials for 14 days after surgery. In particular, cola decreased the resistance of the PGCL suture material more significantly in the first week when compared to other beverages. [ABSTRACT FROM AUTHOR]

Implant surgery in individuals with atrophic maxilla presents challenges, particularly concerning nasal cavity complications such as perforations, implant migration, and airway obstruction. While panoramic radiographs offer diagnostic convenience, their two-dimensional nature limits the evaluation of anatomical structures. Cone beam computed tomography (CBCT) provides a three-dimensional assessment, enhancing surgical planning accuracy and potentially reducing complications. With the aim of understanding the measurement differences between panoramic radiographs and CBCT images, this retrospective study examined CBCT images of patients with severely atrophic maxilla taken between September 2021 and December 2023 at the Ahmet Keleşoğlu Faculty of Dentistry. Virtual implants were placed in various tooth regions using OnDemand3D software. The incidence of nasal cavity perforations and vertical bone height differences between panoramic radiographs and CBCT images were evaluated. For this purpose, vertical bone length measurements in panoramic and CBCT images were compared for the virtual implant placement areas. Statistical analyses, including t-tests and ANOVA, were performed to determine significant differences among quantitative measurements, and a chi square test with Bonferroni corrected z-tests were used for possible associations between ratios. CBCT data from 59 patients, totaling 1888 virtual implants, revealed significant differences in implant depths among tooth regions (F = 9.880, p < 0.001). Canine regions showed higher perforation risks, especially with 12 mm and 14 mm implants. Panoramic radiographs often overestimated vertical bone height in canine and first premolar regions compared to CBCT measurements, which could lead to increased perforation risks. Radiographic evaluations using CBCT prior to implant surgery in atrophic maxilla cases are crucial to prevent nasal cavity complications. Panoramic radiographs may inadequately represent three-dimensional anatomy, underscoring the importance of CBCT for accurate implant placement and surgical planning. Further studies should consider varying implant sizes and brands to generalize findings. [ABSTRACT FROM AUTHOR]

Background: This study aims to determine the position of impacted maxillary canines on cone beam computed tomography (CBCT) images, to determine the presence of resorption in adjacent teeth, and to investigate the position and type of resorption of impacted canines if resorption is present. Methods: Patients over 14 years of age with maxillary canine teeth who had CBCT images taken for any dental reason were included in the study. Resorption of teeth adjacent to maxillary canines was analyzed according to transversal, vertical, and buccopalatinal positions on the CBCT. The study evaluated 162 maxillary canine teeth on tomography images of 134 patients. Results: Of the affected adjacent teeth, 32.1% of the central incisor, 58.0% of the lateral incisor, and 19.1% of the first premolars showed mild-to-severe resorption. The relationships between transversal position and resorption in the central and lateral incisor, vertical position and resorption in the central incisor and buccopalatinal position and resorption in the first premolars were found to be significant. Maxillary canine teeth can cause mild-to-severe resorption of adjacent teeth, especially lateral incisors. Conclusion: For this reason, we think that a detailed examination with CBCT is essential in the early diagnosis of resorption of adjacent teeth. [ABSTRACT FROM AUTHOR]

Backgrounds: Tooth loss in the posterior maxilla often necessitates dental implant placement, but the maxillary sinus anatomy poses challenges, especially during sinus floor elevation. Mesially angled implants are an alternative for total edentulism, but for single tooth deficiencies, palatally angled implants may offer a solution. This study evaluates the prevalence of avoiding sinus floor elevation by placing palatally angled implants in cases with a single missing tooth. Methods: A retrospective study at Ahmet Keleşoğlu Faculty of Dentistry involved 100 participants with a single missing tooth and prior CBCT scans. Virtual implants were placed using OnDemand3D (version 1.0.7462) software. On CBCT sections, implants were angled palatally to avoid sinus or nasal cavity perforation. Statistical analysis was conducted using R and MedCalc (version 4.3.2) software. Results: Of the participants (60% female, average age 50.45), 76 edentulous regions required sinus elevation. The implant placeability rates varied across zones (second molar: 39.3%, first molar: 63.1%, second premolar: 78.5%). Implant placement at a palatal angle was significantly higher in the second premolar and first molar regions. Statistically significant differences were observed in the implant placeability between regions. Conclusions: This study supports the feasibility of avoiding sinus floor elevation through palatally angled implants in specific cases, reducing the associated complications. [ABSTRACT FROM AUTHOR]

In this study, we consider model equations K(m,n) with fractional Caputo time derivatives. By applying the Lie group symmetry method, we determine all symmetries for these equations and present the reduced symmetric equations for the equation K(m,n) with fractional Caputo time derivatives. Furthermore, we obtain the exact solution for K(1,1) with the fractional Caputo time derivative and provide graphs depicting the behavior at different orders of the fractional time derivative. Additionally, by considering the symmetries of the equation, we establish the conservation laws for K(m,m) with the fractional Caputo time derivative. [ABSTRACT FROM AUTHOR]

Coronavirus disease-2019 (COVID-19) was announced as a global epidemic by the World Health Organization in March 2020. The vaccination program against the epidemic in Turkey started on January 13, 2021. Dentists can easily be exposed to viral spread due to their working conditions. However, the uncertainties in the course of the epidemic and the combination of social trends suggest that hesitation will increase against COVID-19 vaccines. We aimed to determine COVID-19 vaccine acceptance rate in dentists. Material and Methods: A new survey was created for dentists after the COVID-19 vaccination program. For the survey, 11 questions about COVID-19 were determined. The survey was conducted between April 1 and April 15, 2021. Results: Of the 467 individuals participating in the study, 293 (63.0%) were female and 172 (37.0%) were male. Among respondents, 421 (90.1%) subjects were vaccinated, 46 (9.9%) subjects refused to be vaccinated for some reasons. No statistically significant relationship was found between vaccination and age (p=0.138) and gender (p=0.322). It seems that there is no relationship between the vaccination status of the physicians and the place they work. Conslusion: Our study shows that dentists in Turkey participate heavily in vaccination. In order to prevent health services from interrupting and to control the epidemic, campaigns and programs should be made to inform the public. Koronavirüs hastalığı-2019 [coronavirus disease-2019 (COVID-19)], Mart 2020 yılında Dünya Sağlık Örgütü tarafından küresel bir salgın olarak ilan edildi. Türkiye'de salgına karşı aşılama programı 13 Ocak 2021 tarihinde başladı. Diş hekimleri, çalışma koşulları nedeniyle kolaylıkla viral yayılıma maruz kalabilirler. Ancak salgının seyrindeki belirsizlikler ve toplumsal eğilimlerin bir araya gelmesi, COVID-19 aşılarına karşı tereddütlerin artacağını gösteriyor. Bu çalışmada, diş hekimlerinde COVID-19 aşısı kabul oranını belirlemeyi amaçladık. Gereç ve Yöntemler: COVID-19 aşılama programının ardından, diş hekimleri için yeni bir anket oluşturuldu. Anket için COVID-19 ile ilgili 11 soru belirlendi. Anket 1 Nisan-15 Nisan 2021 tarihleri arasında gerçekleştirilmiştir. Bulgular: Çalışmaya katılan 467 kişiden; 293'ü (%63,0) kadın, 172'si (%37,0) erkek idi. Ankete katılanların 421'i (%90,1) aşılanmış, 46'sı (%9,9) bazı nedenlerle aşı olmayı reddetmiştir. Aşı ile yaş (p=0,138) ve cinsiyet (p=0,322) arasında istatistiksel olarak anlamlı bir ilişki bulunamadı. Hekimlerin aşı durumları ile çalıştıkları yer arasında bir ilişki olmadığı görülmektedir. Sonuç: Çalışmamız, Türkiye'de diş hekimlerinin aşı çalışmalarına yoğun olarak katıldığını göstermektedir. Sağlık hizmetlerinin kesintiye uğramaması ve salgının kontrol altına alınması için kamuoyunu bilgilendirmeye yönelik kampanyalar ve programlar yapılmalıdır.

Formik asit (metanoikasit, HCOOH) en basit karboksilik asit olup yaygın olarak yem sanayiinde silaj katkısı olarak kullanılır. Formik asit ayrıca deri, parfüm, ilaç, gıda ve kozmetik endüstrisinde geniş bir kullanıma sahip olup, pek çok proseste pH düzenleyici olarak da kullanılır. Formik asidin endüstrideki bu geniş kullanımı gerek üretim proseslerinde ele geçen seyreltik çözeltilerinden, gerekse yan ürün olarak elde edildikleri ortamlardan ya da atık sulardan ayırma ve saflaştırılmalarını önemli kılmaktadır. Formik asidin seyreltik sulu çözeltilerinden ayrılmalarına yönelik olarak literatürde sıvı-sıvı ekstraksiyonu ve reaktif ekstraksiyon çalışmalarına sıkça rastlanmaktadır. Sıvı membranlar düşük enerji ihtiyacı, yüksek seçicilik, ölçeklendirme kolaylığı gibi özellikleri ile karboksilik asitlerin seyreltik sulu çözeltilerinden ayrılmalarında alternatif olarak dikkat çeken bir tekniktir. Bu çalışmada % 10'luk formik asit çözeltisinin yığın membranlarla ayrılmasına yönelik olarak ayırma performansını etkileyen parametreler incelenmiştir. Çalışmamızda öncelikle reaktif ekstraksiyon çalışmaları yapılmıştır. Bu çalışmalarda reaktan olarak tributil amin ve tributil fosfat, seyreltici olarak ise 1-nonanol, etil dekanoat ve etil butirat kullanılmıştır. Farklı başlangıç reaktan konsantrasyonları ile ekstraksiyon etkinliği değerlerinin değişimi incelenmiştir. Yığın membran denemelerinde ise membran fazda seyreltici türü, taşıyıcı türü, besleme : membran: sıyırıcı faz oranları ve sıyırma faz türünün ayırma performansına etkileri incelenmiş ve bu iki ayırma işleminin etkinlikleri karşılaştırılmıştır. Formic acid (methanoic acid, HCOOH) is the simplest carboxylic acid and it is mainly used as silage additive. It is also widely used in rubber, perfume, pharmaceutical and food industries, and also used to regulate the pH of chemical processes. In recent years, the recovery and concentration of formic acid from production media or waste solutions have great importance. In literature, there is a lot of investigations about formic acid recovery from aqueous solutions by liquid-liquid and reactive extraction methods. Liquid membranes, showing comparatively less energy requirement, high selectivity, and easy scale-up factor, are one of the modern and developing techniques for the separation of carboxylic acids from dilute aqueous solutions. In this study, the parameters effecting the separation of aqueous formic acid (10 %, w/w) by bulk liquid membranes are investigated. Once the reactive extraction experiments were studied. 1-nonanol, ethyl decanoate and ethyl butyrate were used as diluents and tributyl amine and tributylphosphate were used as extractants. The effect of initial extractant concentration on the extraction efficiency was determined. In bulk liquid membrane experiments, effects of diluent and extractant types in membrane phase, feed/membrane/strip phase ratio, and strip phase type on the separation process were examined and the investigated separation techniques were compared. 121

İnsanlar için bazı faktörler vardır ki, manevî yapısını olumsuz yönde etkiler. Bunlar, yaşanılan olaylar (kaza ölüm, yangın, haksızlıklar, baskılar vs...) maddî imkânsızlıklar ve bedenî arızalar gibi faktörlerdir. Hasretlik ve sılaya kavuşma arzusunu da bunlara dâhil edebiliriz. İnsanların doğup büyüdüğü toprakları terk etmesi kolay ve keyfi değildir. Bunun için pek çok sebep sıralanabilir. Ancak şurası var ki insanlar kopup geldiği topraklara, geçmişteki günlerine hayatları boyunca hep özlem duyarlar. Toplumun gözü, inancı, düşüncesi hülasa sözcüsü olan âşıklar pek çok konuda olduğu gibi bu konuda da duyarsız kalmamış, şehre göçü ve köye özlem duygularını dile getirmişlerdir. Bildirimizde bize bu konuda düşünme ve yorum yapma imkânı veren Sivas yöresi âşıklarının onlarca şiiri değerlendirmeye tabi tutulacak; âşıklar penceresinden insanların göç sebepleri, şehre uyum sağlayamamaları, özlem duyulan yerler, durumlar, olaylar ve nesneler irdelenip bir sonuca varılacaktır.

BURGERS' equation ,NUMERICAL analysis ,FRACTIONAL calculus - Abstract
The main purpose of this paper is to find an exact solution of the traveling wave equation of a nonlinear time fractional Burgers' equation using the expansion method and the Cole-Hopf transformation. For this purpose, a nonlinear time fractional Burgers' equation with the initial conditions considered. The finite difference method (FDM for short) which is based on the Caputo formula is used and some fractional differentials are introduced. The Burgers' equation is linearized by using the Cole-Hopf transformation for a stability of the FDM. It shows that the FDM is stable for the usage of the Fourier-Von Neumann technique. Accuracy of the method is analyzed in terms of the errors in L
2 and L∞ . All of obtained results are discussed with an example of the Burgers' equation including numerical solutions for different situations of the fractional order and the behavior of potentials u is investigated with graphically. All the obtained numerical results in this study are presented in tables. We used the Mathematica software package in performing this numerical study. [ABSTRACT FROM AUTHOR]- Published

Karşılaştırmalı hukuk ile Türk Hukukunda Ekonomik suçların düzenlenmesindeki gelişim, banka kavramı, Banka faaliyet alanları, Türkiye'de bankacılığın tarihsel gelişimi, banka suçu kavramı, Türk mevzuatının bu konudaki gelişimi ilgili bölümlerde ayrıntılı bir şekilde açıklanmıştır. 4389 sayılı Bankalar kanununda yer alan adli ve idari suçların ayrılma kriterleri, 01.06.2005 tarihinde yürürlüğe girecek olan 5326 sayılı `Kabahatler Kanunu`nun getirdiği yeni düzenlemelerde göz önünde bulundurularak ele alınmıştır, idari suç tipleri kısa bir şekilde açıklandıktan sonra, Bankalar Kanununda yer alan on yedi ayrı adli suç tipi ceza hukukunun inceleme kalıplan içerisinde tek tek ele alınarak ayrıntılı bir şekilde incelenmiştir. Çalışmamıza, 01.06.2005 tarihinde yürürlüğe girecek ve Türk Ceza hukuku sistemini büyük oranda değiştirecek olan, 5237 sayılı Türk Ceza Kanunu, 5271 sayılı Ceza Muhakemeleri Kanunu, 5326 sayılı Kabahatler Kanunu ve 5275 sayılı Ceza ve Güvenlik Tedbirlerinin İnfazı Hakkında Kanunun getirdiği yeni düzenlemeler yansıtılmıştır. 5020 sayılı yasa ile Bankalar Kanununa eklenen `Banka hakim ortaklarının zimmeti suçu` ve `Bankacılık izni kaldırılan bir bankadan, tasarruf mevduat hesabı bulunmamasına rağmen, sahte belgelerle kendisine veya bir başkasına ödeme yapılmasını talep etmek veya ödeme yapılmasına neden olmak suçlan` çalışmamıza dahil edilmiştir. Yürürlükte bulunan 4389 sayılı Bankalar kanunu, önceki Bankalar Kanunlarına göre ileri bir noktadaysa da, atıf sisteminin halen devam ettiriliyor olması, bazı suç tiplerinde ceza hadleri arasında (örneğin 10 yıldan 20 yıla kadar gibi) büyük farklılıkların bulunması, neredeyse tüm suç tiplerinin tek madde de düzenlenmesi gibi problemleri bünyesinde barındırmaktadır. Henüz yasalaşma aşamasında olan Bankalar Kanunu tasarısında her suç tipi ayrı maddelerde ele alınmış ancak yine atıf usulüne devam edilmiştir. DC ABSTRACT Aim of this study is investigated judicial crimes as punishments that were arranged with the Banking Law numerated 4389. The concept of economic crime is considered in the contents of `white color crime`. The development of organizing economic crimes in Turkish law with the comparative law, concept of banking, banking range of activities, improvement of banking in Turkey, issue of bank crime and development of Turkish laws on this issue are explained in detail at the related chapters. The separation criteria of judiciary and administrative crimes according to banking law no 4389 are evaluated by considering the arrangements that is brought by `Faults Law` no: 5326 coming into effeetin 01.06.2005. After the administrative crimes are explain shortly, it judiciary crime types taking place banking are analyzed one by one in the view of criminal law. In the thesis, Turkish Criminal Law no: 5237, Criminal Procedure Law no: 5271, Faults Law No: 5326. Law of punishment and security measures execution no 5275 coming into effect 01.06.2005 were assessed. Banking Law no 4389 that is still in force, better than the previous banking law. However The New Banking Law has some of defectiveness like as the referring system is continuous, punishments rates have big gap in the some type of crime, and almost all type of crimes was ordered under an article. 220

Most of the ballads in TRT repertoire have own story on their origins. However, numbers of the ones, the stories of which are known, are too limited. The ballad of Zeynep, which is registered in TRT repertoire with number 331, is one of such ballads. Although there are different types of narrations about this ballad, there are very few common points between them.It is needed to find out some factors related to the identity of a ballad. In concern with the ballad in this study, it is required to put forward some results about Zeynep's birth date and death date, her hometown and family, whom she got married, singing the elegy, collecting the ballad, deploy places. Has this elegy been sung upon the killing of Zeynep or sung by someone who fell in love her but could not attain his desire? The folk have embraced the ballad, the lyrics and melody of it have also been liked, and over time it has been accepted that the story told in ballad has came true in its own region. Besides the ballad of Zeynep, with similar or different lyrics, is seen in some regions such as Elazığ, Kirkuk, even Macedonia. In this study, it has been tried to clarify these issues by utilizing both from narrations and the lyrics of ballad and the findings and thoughts have been given by evaluating the data.

In Folk Literature, there are lots of subjects which have not never been studied on before or studied slightly. One of those is genre of salavatlama. In Islam World, to say "salavat" after the Prophet Muhammed's name expresses his importance. Religious connations of salâvatlama which aim to express good wishes are also very important in folk culture. Salavatlamas are expressions in verse that are said in wedding, harvesting and wrestling competitions. Today, farmers reap their harvest with harvester through technological developments. Thus harvesting salâvatlamas have disappeared in folk culture. However, salâvatlamas have still continued their existence in wedding ceremonies and in wrestling competitions. Morover, salavatlamas in Sivas which have been taken as a case in this study have partially continued their existence. [ABSTRACT FROM AUTHOR]

By considering the Adomian decomposition scheme, we solve a generalized Boussinesq equation. The method does not need linearization or weak nonlinearly assumptions. By using this scheme, the solutions are calculated in the form of a convergent power series with easily computable components. The decomposition series analytic solution of the problem is quickly obtained by observing the existence of the self-canceling "noise" terms where sum of components vanishes in the limit.

Bunun yanı sıra difüzyon olayının matematiksel modeli olan zaman-kesirli Harry-Dym denklemlerinin ba¸slangıç sınır de?ger problemlerine Lie grup yöntemini uygulayarak, klasik dalga dönü¸sümü kullanmadan, bazı cebirsel formda olan analitik çözümler elde ettik. Anahtar Kelimeler: Caputo türevi, Lie simetri yöntemi, lineer olmayan kısmi diferansiyel denklemler için ba¸slangıç ve sınır de?ger problemi, Riemann-Liouville türevi. ABSTRACT In this doctoral thesis, we focused on the solution of problems modeled by nonlinear fractional derivative partial differential equations. In the study process, we obtained the analytical solutions of some nonlinear fractional order differential equations by using the Lie group (symmetry) method, which is one of the methods of classical transformation methods to obtain solutions of linear and nonlinear partial differential equations, and also investigate conservation laws. Also, we created Lie group theory for the initial and boundary value problems of partial differential equations containing Caputo derivatives. Therewithal, by applying the Lie group method to the initial boundary value problems of the time-fractional Harry-Dym equations, which is the mathematical model of the diffusion event, we have obtained some analytical solutions algebraic form without using classical wave transformation. Keywords: Caputo derivative, Initial and boundary value problems for nonlinear partial differential equations, Lie symmetry method, Riemann-Liouville derivative.

We demonstrate cascade manipulation between magic number gold-fullerene hybrid clusters by channelling thermal energy into a specific reaction pathway with a trigger from the tip of a scanning tunnelling microscope (STM). The (C-60)(m)-Au-n clusters, formed via self-assembly on the Au(111) surface, consist of n Au atoms and m C-60 molecules; the three smallest stable clusters are (C-60)(7)-Au-19, (C-60)(10)-Au-35, and (C-60)(12)-Au-49. The manipulation cascade was initiated by driving the STM tip into the cluster followed by tip retraction. Temporary, partial fragmentation of the cluster was followed by reorganization. Self-selection of the correct numbers of Au atoms and C-60 molecules led to the formation of the next magic number cluster. This cascade manipulation is efficient and facile with an extremely high selectivity. It offers a way to perform on-surface tailoring of atomic and molecular clusters by harnessing thermal energy, which is known as the principal enemy of the quest to achieve ultimate structural control with the STM.
