Islamophobia from the inside: how Turkish immigrants responded to the securitization of integration in Germany and the Netherlands
No full textAlthough there is a vast literature on the securitization and Islamophobia phenomena in Western societies, there is relatively less research about the perceptions and mobilization of Muslim immigrants in the West, especially Turks, with respect to these phenomena. Therefore, the research set out to explore whether there has been any change in the forms of mobilization of Turkish immigrants in Germany and the Netherlands after 9/11 as a response to the securitization of integration. The present comparative study identified not only the changes after 9/11, but also the main similarities and differences between the two cases. Characteristics of Turkish immigrants and the context of reception, as well as the subjective aspects (such as perceptions, feelings, emotions, and so on) related to the issue were taken into account in the study. From the methodological perspective, the study employed a mixed methods research approach by including interviews, participant observation, and a quantitative analysis of population and political representation data. In total, in Germany and the Netherlands, 27 face to face semi-structured interviews were conducted with either the representatives of Turkish organizations or the political party members that originated from Turkey. The study concluded that Turkish immigrants in both countries have been negatively affected by the securitization process. They felt that they faced more problems (such as discrimination, hate crimes, more restrictive policies towards them, and so on) in their contexts after 9/11. Along with these perceptions, the changes in their characteristics and the context of reception played an important role in their mobilization in this process. The study revealed that they became more mobilized and organized after 9/11. After evaluating the motives and objectives of mobilization and acculturation strategies of Turkish immigrants, the study identified three main forms of mobilization (political, social, and cultural) as a response to the securitization of integration. Not only differences between the characteristics of Turkish immigrants in Germany and the Netherlands but also dissimilarities in their receiving contexts resulted in differences in their political mobilization approaches. However, their social and cultural mobilization approaches in both countries have mainly been similar.Ph.D.Includes bibliographical referencesIncludes vitaby Esref Ertur
Comparison of AO, Schatzker, and three-column classification systems in tibial plateau fractures: Impact on functional outcomes
No full textObjectives: This study aimed to compare the AO, Schatzker, and Three-Column classification systems for tibial plateau fractures, focusing on their prognostic and functional outcome prediction and influence on clinical decisions across different trauma types. Patients and methods: In this retrospective study, we examined 49 patients (36 males, 11 females; mean age: 40.6 +/- 11.8 years; range, 19 to 67 years) with tibial plateau fractures between January 2011 and January 2017. The fractures were classified using the AO, Schatzker, and three-column systems. The main outcome measurements included functional scores (Knee Injury and Osteoarthritis Outcome Score [KOOS], Hospital for Special Surgery [HSS]), range of motion (ROM), duration of hospitalization, thigh atrophy, operation time, and the development of osteoarthritis. The impact of smoking was also assessed. Results: According to the AO classification, type B fractures obtained higher KOOS and HSS scores compared to type C fractures (p=0.013 and p=0.007, respectively). According to the Schatzker classification low-energy fractures achieved higher KOOS and HSS scores than high-energy fractures (p=0.013 and p=0.026, respectively). One-column fractures had higher KOOS and HSS scores compared to two-column and three-column fractures (p=0.007 and p=0.001, respectively). Two-column fractures had a lower ROM compared to other column fractures (p=0.022). Shorter hospital stays were recorded for Schatzker low-energy fractures (p=0.016), whereas higher thigh atrophy was found in Schatzker high-energy fractures (p=0.022) and AO type C fractures (p=0.018). Longer operation times were observed in AO type C fractures (p=0.037) and Schatzker high-energy fractures (p=0.017). According to the Kellgren-Lawrence classification, AO type C fractures and three-column fractures yielded worse outcomes (p=0.039 and p=0.001, respectively). Smoking had a negative impact on functional KOOS and HSS scores across all groups (p=0.022 and p=0.001, respectively). Conclusion: This study highlights the predictive value of the AO, Schatzker, and Three-Column classification systems in determining functional outcomes and clinical data in tibial plateau fractures. Each system provides unique insights into different outcomes, suggesting their concurrent application may yield a more comprehensive prognosis
Tumors of the spine
No full textSpine tumors comprise a small percentage of reasons for back pain and other symptoms originating in the spine. The majority of the tumors involving the spinal column are metastases of visceral organ cancers which are mostly seen in older patients. Primary musculoskeletal system sarcomas involving the spinal column are rare. Benign tumors and tumor-like lesions of the musculoskeletal system are mostly seen in young patients and often cause instability and canal compromise. Optimal diagnosis and treatment of spine tumors require a multidisciplinary approach and thorough knowledge of both spine surgery and musculoskeletal tumor surgery. Either primary or metastatic tumors involving the spine are demanding problems in terms of diagnosis and treatment. Spinal instability and neurological compromise are the main and critical problems in patients with tumors of the spinal column. In the past, only a few treatment options aiming short-term control were available for treatment of primary and metastatic spine tumors. Spine surgeons adapted their approach for spine tumors according to orthopaedic oncologic principles in the last 20 years. Advances in imaging, surgical techniques and implant technology resulted in better diagnosis and surgical treatment options, especially for primary tumors. Also, modern chemotherapy drugs and regimens with new radiotherapy and radiosurgery options caused moderate to long-term local and systemic control for even primary sarcomas involving the spinal column
Why does tension band wiring fail in transverse patellar fractures? Radiographic insights from a 10-years retrospective cohort
No full textBackground The aim of this study was to identify the radiographic parameters associated with failure of tension band wiring (TBW) in the treatment of transverse patellar fractures, with the goal of guiding surgical decision-making. Materials and methods A total of 76 patients underwent surgical treatment for patellar fractures at Trakya University between January 2013 and December 2022. We retrospectively analyzed 32 patients who met the study's inclusion criteria for transverse fractures (AO Type 34- C1) treated with TBW. Radiographic parameters assessed included patellar width, inter-K-wire distance, K-wire-to-patella ratios, knot configuration, and K-wire length, all evaluated for their potential association with fixation failure. Failure was defined as cerclage wire slippage or breakage. Statistical analyses were conducted using SPSS and Jamovi software. Descriptive statistics, t-tests, chi-square or Fisher's exact tests, logistic regression, and ROC analysis were performed. A p-value < 0.05 was considered significant. Results The mean age was 50 years +/- 15.8 (range 26-80), with 8 women (25%) and 24 men (75%). Nine patients (28.1%) experienced TBW failure. Notably, single-knot constructs had significantly higher failure rates (66.7% vs. 19.2%; OR = 0.119, 95% CI [0.017-0.843], p = 0.038). Increased K-wire length was associated with failure (p = 0.008; cutoff 69.1 mm, AUC = 0.785). Patella-K-wire length ratio was higher in failures (p = 0.035). Lateral K-wire to articular distance and lateral K-wire to articular distance surface to patella thickness ratio were also significant predictors in slippage group (p = 0.046 and p = 0.031). Conclusion The number of knots, K-wire length, and specific radiographic parameters are important predictors of TBW failure. Attention to construct configuration and K-wire placement is crucial to minimize failure risk

biographical facts of the poet's life, his spiritual state, world and some of the main important points that have
been evaluated by himself in the genre of lyric confession.
It is said that "you don’t become a poet, you have to be born as a poet." This statement can be referred to the
lyrics of Eshref Shemi - zade. The motive of confession certainly has a connection with the personal life of the
author, with his spiritual state. Genre of lyrical confession has not been subjected to thorough deep analysis, a
similar study in the works of Eshref Shemi -zade occurs for the first time.
If we line up the lyrical works in chronological order, we can see that the narrative reveal to us the events
corresponding to such periods of his life, like childhood, adolescence and adulthood. In the memories of the poet
- biography of the whole generation, his fate, dramatic events that having united as a whole, determined his fate
and character. All these things he expresses through the image of lyrical character. Lyrics of Eshref Shemi -
zade is deeply personal and confessional. The most common narrative in his works is in first person. The
language of these works is a bit like the language of lyrical writing, and it has a huge emotional impact on the
reader. Author's reflections, the findings could be kind of a model and example for the reader. The events
connected with the life and work of the poet, as if alive before our eyes. As a rule, a confession does not allow
the lies, it is sincere and truthful. A characteristic feature of Eshref Shemi - zade’s works – is a method of
transmitting lyrical «I» by poet, in which frank confessions reveal his inner spiritual content. This method of
self-discovery is a part of his artistic world
Isolation and Characterisation of Bacteria From an Extremely High Boron and Salinity-Tolerant Puccinellia distans (Jacq.) Parl. Rhizosphere and Their Potential Impact on the Growth of Bread Wheat (Triticum aestivum L.)
No full textBoron toxicity and salinity are major abiotic stress factors that cause significant yield losses, particularly in arid and semi-arid regions. Hyperaccumulator plants, such as Puccinella distans (Jacq.) Parl. from Kirka, exhibit remarkable tolerance to these stresses. This study isolated nine boron-tolerant and six salinity-tolerant bacterial strains from the rhizosphere of P. distans. Using BLAST analysis of 16S rRNA sequences, the boron-tolerant bacteria were identified as Sphingobacterium detergens (three strains), Achromobacter spanius, Pseudomonas extremorientalis, Olivibacter soli, Puccinella poae, Zhihengliuella halotolerans and Chryseobacterium sp., while the salinity-tolerant strains included Bacillus toyonensis, B. muralis, Staphylococcus warneri, Staphylococcus aureus (two strains) and Arthrobacter aurescens. Among these, P. poae stood out as a promising plant growth-promoting rhizobacteria (PGPR) candidate. A greenhouse pot experiment demonstrated that inoculating Triticum aestivum L. with P. poae under varying boron doses significantly enhanced plant growth. Notable increases were observed in plant height, root length, stem fresh weight and emergence ratio. These findings highlight the potential of P. poae as an eco-friendly microbial fertiliser to enhance crop resilience in boron-affected areas and offer a sustainable alternative to chemical fertilisers, thus improving agricultural productivity under abiotic stress conditions.The Council of Higher Education of Turkey (YK), 100/2000 Doctoral Scholarship ProgramThis work was supported by the Turkiye Bilimsel ve Teknolojik Arast & imath;rma Kurumu, Selcuk Universitesi, Ege Universitesi.

Augmented Reality: A New Tool To Improve Surgical Accuracy during Laparoscopic Partial Nephrectomy? Preliminary In Vitro and In Vivo Results
No full textBackground: Use of an augmented reality (AR)-based soft tissue navigation system in urologic laparoscopic surgery is an evolving technique. Objective: To evaluate a novel soft tissue navigation system developed to enhance the surgeon's perception and to provide decision-making guidance directly before initiation of kidney resection for laparoscopic partial nephrectomy (LPN). Design, setting, and participants: Custom-designed navigation aids, a mobile C-arm capable of cone-beam imaging, and a standard personal computer were used. The feasibility and reproducibility of inside-out tracking principles were evaluated in a porcine model with an artificially created intraparenchymal tumor in vitro. The same algorithm was then incorporated into clinical practice during LPN. Interventions: Evaluation of a fully automated inside-out tracking system was repeated in exactly the same way for 10 different porcine renal units. Additionally, 10 patients underwent retroperitoneal LPNs under manual AR guidance by one surgeon. Measurements: The navigation errors and image-acquisition times were determined in vitro. The mean operative time, time to locate the tumor, and positive surgical margin were assessed in vivo. Results and limitations: The system was able to navigate and superpose the virtually created images and real-time images with an error margin of only 0.5 mm, and fully automated initial image acquisition took 40 ms. The mean operative time was 165 min (range: 135-195 min), and mean time to locate the tumor was 20 min (range: 1327 min). None of the cases required conversion to open surgery. Definitive histology revealed tumor-free margins in all 10 cases. Conclusions: This novel AR tracking system proved to be functional with a reasonable margin of error and image-to-image registration time. Mounting the pre- or intraoperative imaging properties on real-time videoendoscopic images in a real-time manner will simplify and increase the precision of laparoscopic procedures.
