Mechanical characterization and microstructure of fiber laser welded TWIP980 steel depending on welding speed and focal distance
(Elsevier, 2023) Çavuşoğlu, Oktay; Yuce, C.; Aydın, H.
The TWIP steels are preferred in the automotive industry due to excellent strength and ductility. In this study, the effect of fiber laser welding parameters has been investigated on the mechanical properties and microstructural points of view twinning-induced plasticity (TWIP) steel. The variation of the mechanical properties depending on fiber laser welding parameters has been determined. The samples were laser-welded with different speeds and focal distances the laser power constant at 4 kW. The stress and elongation decreased when the welding speed increased. The highest stress was obtained at + 1 focal distance. The best energy absorption was seen in b-3 combination (laser power 4 kW, welding speed 130 mm/s, focal distance +1 mm)

(Gazi Üniversitesi, 2022) Okuroğulları, Y.; Çavuşoğlu, Oktay; Tutar, M.; Aydın, H.
In this study, the effect of the changes in welding parameters on the tensile strength, which is one of the mechanical properties of the steels, was investigated in the robotic gas arc welding method applied to St52 and S460MC steels, which are widely used in the industry. As a result of the experiments carried out within the scope of the study, it was aimed to determine the optimum parameter values for the MAG welding method. St52 and S460MC materials were used in the experiments. An experimental design was created in order to carry out the experiments in the most accurate way. Parameter val-ues are placed in this created experimental design. As a result of the experiments per-formed according to the created the experimental design, the optimum parameter val-ues were examined, welding processes were applied with the selected values, and the improvements in the welding quality were determined by subjecting the welded samples to the tensile test. The optimum welding parameters providing the best mechanical properties were 25 V, 7 mm/sec and 13 mm/sec for the arc voltage, wire feed speed and welding speed, respectively.
Influence of oscillating fiber laser welding process parameters on the fatigue response and mechanical performance of butt-jointed TWIP980 steels
(De Gruyter Brill, 2025) Çavuşoğlu, Oktay; Aydın, H.; Eroglu, M.; Davut, K.
In this study, the effect of laser power, welding speed, linear heat inputs on the mechanical performance of TWIP980 steels joined by oscillating fiber laser welding in butt welding configuration was investigated. Oscillating fiber laser welding were changed: laser power from 1.2 to 1.6?kW, welding speed from 20 to 30?mm?s?1, linear heat input from 40 to 80?J?mm?1. The tensile, hardness and fatigue tests were carried out to determine mechanical performance. A significant improvement in weld penetration, fatigue performance and mechanical properties was detected at linear heat inputs above 53.33?J?mm?1. The best mechanical properties were obtained at 1.6?kW laser power and 25?mm?s?1 welding speed. The study reveals that linear heat inputs, laser power, and welding speed have significant effects on mechanical performance and weld geometry. Furthermore, the results demonstrate that oscillating fiber laser welding enables good weldability even at low laser power.
Triple joining of different sheets with self-pierce riveting method
(SAGE, 2022) Çavuşoğlu, Oktay; Bakırcı, A.; Dinkçi, H.; Yılmazoğlu, A. G.
Self-piercing riveting (SPR) is a high-speed mechanical joining technique for sheet metal materials. In this study, the mechanical properties of DC04 steel and AA5182 aluminium alloy in triple combinations joined by the SPR method were investigated. For this purpose, triple-joining processes were performed in different combinations, and macro-structural analysis and tensile shear tests were carried out by comparing their mechanical properties. As a result of the study, the highest shear forces were obtained in FFA (DC04-DC04-AA5182) and AFF (AA5182-DC04-DC04) combinations. As the number of aluminium layers increases, the probability of tearing increases in triple joining. Higher spread ratios were generally measured under conditions with hard materials in the upper layers and soft materials in the lower layers
Microstructural features and mechanical properties of 22MnB5 hot stamping steel in different heat treatment conditions
(Elsevier, 2020) Çavuşoğlu, Oktay; Çavuşoğlu, Oktay; Yılmazoğlu, A. G.; Üzel, U.; Aydın, H.; Güral, A.
In this study, the microstructure and mechanical properties of the 22MnB5 steel sheet were investigated in different heat treatment conditions. The steel sheet heated to 700?°C, 800?°C, and 900?°C was subjected to air cooling, water quenching, and water quenching?+?tempering procedures. Microstructural properties post-heat treatment were analyzed under an optical microscope. To determine the mechanical properties, uniaxial tensile tests, and hardness measurements were performed. The highest mechanical properties were achieved with the water quenching from 800?°C and 900?°C. The elongation value was ranged of 2-4% with the water quenching. Also, the tempering process slightly increased the elongation value.

Otomotiv, havacılık, uzay ve savunma endüstrilerindeki hızlı gelişim hafif ve yüksek mukavemetli malzemelerin kullanımını gerekli kılmıştır. Bu amaçla cam elyaf takviyeli plastik kompozit malzemeler üretilmeye başlanmış ve yaygın bir şekilde kullanılmıştır. CTP’nin farklı yüklere karşı dayanımı, çok yüksek korozyon dayanımı (yapısal olarak çelik ve ahşap malzemeye göre çürüme ve paslanma olmamasından dolayı periyodik bakıma ihtiyaç duyulmaması), hafifliği, montaj ve işçilik kolaylığı, kısa zamanda imalatı gibi özelliklere sahip olması bu malzemelerin yapılarda kullanılırken diğer geleneksel malzemelere karşı üstünlüğünün bir göstergesidir. Bütün bu özelliklerinin bir sonucu olarak CTP’ler yüksek basınçlı boru üretiminde de kullanılmaktadırlar. Bu araştırmada, CTP’lerin boru üretimindeki yeri ve önemine değinilmiş, CTP boru üretiminde kullanılan hammaddeler ve özelliklerinden bahsedilmiştir. Bunun yanında, CTP boru üretim yöntemleri açıklanmış ve üretilen CTP boruların sınıflandırılması, teknik özellikleri, kısa dönem performans deney yöntemleri belirtilmiştir. Ayrıca farklı projeler için tasarlanabilecek ve çeşitli ihtiyaçlara cevap verebilen daha yüksek performanslı CTP boru üretimine yönelik önerilerde bulunulmuştur
Polyimide strengthened cement mortar
(WALTER DE GRUYTER GMBH, 2024) Poyraz, Bayram; Dayı, Mustafa
This study examined the effects of silane-modified polyimide polymer (PIS) on cement mortar. The PIS was added to replace cement in a specified ratio. Obtained results revealed that the PIS caused retardation on setting time, and accelerated UPV mostly by encapsulating unhydrated cement particles, filling pores, or reacting with C-S-H and Ca(OH)2 with shifting to Si-O vibrations. SEM results showed a good compact interface without forming considerable agglomeration and voids on the microstructure, and this improved flexural and compressive strength properties. In conclusion, silane-modified polyimide as an admixture or cement replacement can be recommended for construction industries to enhance the properties of cement mortar.

Sepsis Multi Organ Damage Due To Secondary Immune Failure After Spondylodiscitis
(Anestezi Dergisi, 2023) Şenoglu, G.D.; Demiraran, Y.; Yazar, Z.
Background: Surgical trauma may affect immunity and pave the way for septic complications. In our case, the intensive care follow-up of a patient who developed spondylodiscitis and diagnosed with immunodeficiency and ARDS-Sepsis was presented, and the literature was reviewed. Case: A 36-year-old male patient became immobile with severe pain after a lumbar disc hernia repair twenty-eight days ago. Antibiotherapy was started after the diagnosis of Spondylodiscitis by MRI (Figure 1). Due to his clinical deterioration, he was transferred to our intensive care unit with the preliminary diagnosis of ARDS-sepsis and acute renal failure. There were tachycardia, hypotension, hypoxia, anuria, with no infective findings in the operation area. Continuous venovenous hemodialysis and cytokine filter were applied to the patient. The cytokine filter was terminated on the third day with the regression of ARDS and infective parameters (Table 1), and the patient was followed up with high flow (fi0,:100 flow:60L/min). Hypoxia became evident on the seventh day, and the patient had to be intubated on the tenth day. Antibiotherapy was expanded due to acinetobacter and hyphae in deep tracheal aspirate. Deepening of thrombocytopenia was thought to be related to antibiotics. IgG level was 569 mg/dL (700-1600 mg/dL). Intravenous Ig (IVIG) was administered. As the cytopenia continued, it was thought that infection-related immune thrombocytopenia might have been added, and IVIG was planned again, the treatment was completed with clinical response. After sixty days of intensive care follow-up, the patient was removed from the intensive care unit by closing the tracheotomy. Conclusion: Spondylodiscitis is usually bacterial and occurs after surgery. Complications, constant source of infection, and prolonged antibiotic therapy may lead to multiple organ dysfunction syndrome (MODS) due to uncompensated excessive and prolonged proinflammatory responses in patients. Long-term hospitalization after surgery, immobility, malnutrition are predisposing factors to sepsis; it also reveals the imbalance of inflammatory and anti- inflammatory processes. Thus, prolonged immunodeficiency findings can be observed. The patient, who developed MODS and secondary immunodeficiency, was discharged after meticulous multidisciplinary follow-up. In conclusion, it should be kept in mind that the immune system may be suppressed in young and low-risk patients and the resulting sepsis may cause multi-organ damage. © 2023 Anestezi Dergisi.

Creating a Mobile Application to be Evaluated as a Presentation Technique in Landscape Design
(Peter Lang Publishing Group, 2023) Benliay, A.; Kıvanç, Ak, M.
The use of computer technologies in architecture, as in all fields, has become more intense and flexible than ever before, as the computer has become a part of daily life. The increased use of computers has resulted in the digitalization of architectural information, which has transformed the structure of information as well as the method it is created and preserved. The computer, which was once viewed solely as a presentation tool, has recently begun to play an essential role in education and design processes, in addition to serving as a presentation tool in architecture. Also, with the developments in mobile technologies, we use devices with powerful processors and operating systems that we can carry with us all the time. These devices have started to take their place in our lives as indispensable tools for many of us. In addition to the increase in the number of applications to be used in these devices, individuals have begun to acquire the infrastructure to create their own software. In this study, it was aimed to examine an area in the design phase from the people design by turning it into an application on the mobile device. 3D modeling of a landscape design element was made with SketchUp software, and then it was transformed into an application that can be interacted with and freely navigated using Unity software. One hundred participants were asked to download and use the created software on their mobile phones. A questionnaire consisting of twelve questions was prepared for the evaluation of these individuals and the individuals participating in the study were asked to fill it out. To train the artificial neural network model, nine of the answers given to the twelve questions were used as input to the artificial neural network model and three were used as output data. Correlations between input and output data were determined with the help of the simulation prepared using the Deep Learning model. In this way, it was tried to determine who could be the people who could give the most positive and the most negative answers to the questions prepared to measure the usability of the software prepared besides the most relevant topics. Also, as a result of the study, suggestions were developed for future studies. © 2023 Peter Lang GmbH, Internationaler Verlag der Wissenschaften.
Interpretation of Landscape Sensitivity and River Habitat Assessment Approaches Based on Cultural Landscape Elements: The Edirne Sarayiçi Case
(Peter Lang Publishing Group, 2023) Keleş, E.; Uzun, O.
Edirne is an important historical and cultural urban center since it has been the home of several civilizations throughout history. Edirne is a border town with cultural diversity. Furthermore, the Maritsa, Tunca and Arda rivers that divide the city are also significant natural landscape elements. These rivers are international waters and have been important factors in urban structure and serve as a natural corridor around the urban center. In recent years, the city has experienced problems such as population growth, urbanization, tourism, increase in impervious surfaces, damage to natural corridors, and urban or rural floods. Thus, planning and management of these areas are quite important to ensure sustainability. The present study aims to determine the landscape sensitivity in Edirne Sarayiçi region that includes various natural, historical and cultural assets. Thus, landscape function analyzes (water function, habitat, erosion function and cultural status) were conducted and the landscape sensitivity was determined by ovarlay the maps. The condition of the river habitats was analyzed with field work in and around the Tunca river. The analysis of the Sarayiçi region landscapes revealed that the landscape sensitivity was low; however, the presence of historical and cultural assets in the area and frequent floods damaged the river habitats and increased landscape sensitivity. Thus, recommendations for the restoration and conservation of the landscape are presented to preserve natural and cultural components and ensure the sustainability of historical assets © 2023 Peter Lang GmbH, Internationaler Verlag der Wissenschaften.
The effect of crude and calcined sepiolite on some physical and mechanical properties of glass fiber reinforced concrete
(Fundatia Serban Solacolu, 2023) Saka, R.C.; Subasi, S.; Marasli, M.
The technical term GRC (glass fiber reinforced concrete) is widely used in the precast industry. This type of concrete, which is obtained by mixing cement, sand, glass fibers and some chemicals, is very durable. Compared to conventional concretes, high compressive, flexural and impact strength is the preferred choice for building facade coatings. In this paper, the usability of sepiolite as a pozzolan in glass fiber reinforced concrete and its effects on mechanical and physical properties were investigated. GRC samples were produced by adding 3% glass fiber by volume to substituted mixtures. Crude and calcined sepiolites were replaced with cement at 5%, 10%, 15% and 20% by weight. Compressive strength, flexural strength, impact strength and abrasion resistance of produced GRC samples were determined. As a result, It was observed that as sepiolite ratio increased, mechanical and physical properties of samples decreased in early and later ages, and crude sepiolite substituted samples had lower mechanical strength than the calcined sepiolite substituted samples. © 2023, Fundatia Serban Solacolu.

Cerebrospinal Fluid - Cutaneous Fistula After Combined Spinal Epidural Anesthesia in a Non-Obstetric Patient Treated With an Epidural Blood Patch: A Case Report
(Anestezi Dergisi, 2023) Karka, Ö.E.; Demiraran, Y.; Sobcali, G.
Background: We aimed to discuss the successful treatment of cerebrospinal fluid (CSF)-cutaneous fistula which is caused by combined spinal epidural anesthesia (CSE), with an autologous epidural blood patch (EBP), further investigation and antibiotherapy. Case: CSE was applied for a total hip replacement. Since CSF was seen in the first attempt, CSE was achieved in the second attempt using the same Tuohy needle. Postoperatively epidural catheter was used for analgesic purposes for 2 days. After the catheter removal, anesthesia consultation was requested due to the patient's wet back. A clear fluid leak at the needle insertion point was observed. A sample was taken and the differential diagnosis of CSF-skin fistula was made biochemically with the presence of glucose and chloride. The patient denied headaches. Neurological examination was normal. With patient's consent, EBP was performed. During the injection CSF leak was slowed down, the last drops were macroscopically hemorrhagic and eventually the leak stopped. Headache, dizziness, and nausea occurred on the 2nd day after EBP. Neurological examination was normal. No dural defect or CSF collection was observed in brain CT, brain diffusion MR and contrast-enhanced MR myelography. Ceftriaxone, metronidazole and a pneumococcal vaccine were added for meningitis prophylaxis in consensus with infection and neurology consultants. 1-month follow-up was performed telephonically and the patient was completely cured. Conclusion: Cerebrospinal fluid (CSF)-cutaneous fistula is a rare complication of neuraxial anesthesia techniques. Since there are no sufficient guidelines for management, the decision on the treatment method depends on the clinician's aspect. We consider that it would be advantageous to prefer EBP primarily in cases with CSF-skin fistula and that the benefit/harm ratio is higher than the complications to be caused by a subarachnoid space that is fistulized to skin and opened out to cutaneous flora. In the literature, the development of meningitis has been reported in some cases followed up under conservative treatment or skin sutures. Although prophylactic use should be avoided as possible due to increasing antibiotic resistance, our opinion is that clinicians should decide for each case, taking into account the conditions such as hospital infection surveillance and the flora of inpatient service. © 2023 Anestezi Dergisi.

Investigation of Form Feature in Urban Road Trees within the Context of Aesthetic Perception; Case of Kocaeli- Başiskele- Alsancak Avenue
(Peter Lang Publishing Group, 2023) Kıvanç, Ak, M.; Benliay, A.
Urban ecosystems show significant differences when compared to natural ecosystems. The most important reason for this is the anthropogenic effect. These differences are; dense construction, industrial facilities, dense population, heat island, urban activities, air pollution, soil conditions, etc. factors can be listed. On the other hand, green areas in cities are the only places where people are together with nature and benefit from its functions. One of the places where trees, which are the most important elements of green areas, is the closest and most beneficial to people, is road routes. Road trees constitute an important part of the green areas in the city. Road trees are natural elements that need attention in their planning and design, as they are always intertwined with the people living in the city. Functionally and aesthetically correctly planted urban roads have an important place in the urban landscape as the continuation of the green areas of the city and the green passages connecting them, as complementary elements to the organic integrity. Urban road trees are the trees that are most negatively affected by the environment in terms of their location. Therefore, they require more attention and sensitivity than other afforestation studies. In addition to the functional properties of road trees such as improving the urban climate, bringing human scale to the city, and psychological features; it is known that visual features also contribute. This study tries to determine how people perceive the aesthetic features of road trees in terms of form in the example of Kocaeli- Başiskele- Alsancak Street and its close surroundings. In this context, trees; it has been discussed in three main form features as circle, pyramid and scattered. These form features were also evaluated over the user group in line with six different adjective pairs. The results of the research reveal that especially the circular road trees are positively differentiated in terms of human perception. © 2023 Peter Lang GmbH, Internationaler Verlag der Wissenschaften.
Critical equimatchable graphs
(University of Queensland, 2024) Deniz, Z.; Ekim, T.
A graph G is equimatchable if every maximal matching of G has the same cardinality. In this paper, we investigate equimatchable graphs such that the removal of any edge creates a graph that is not equimatchable, called edge-critical equimatchable graphs (ECE-graphs). We show that apart from two simple cases, namely bipartite ECE-graphs and even cliques, all ECE-graphs are 2-connected factor-critical. Accordingly, we give a characterization of factor-critical ECE-graphs with connectivity 2. Our result provides a partial answer to an open question posed by Levit and Mandrescu [Eur. J. Comb. 20 (2019), 261–272] on the characterization of well-covered graphs with no shedding vertex. We also introduce equimatchable graphs such that the removal of any vertex creates a graph that is not equimatchable, called vertex-critical equimatchable graphs (VCEgraphs). To conclude, we clarify the relationship between various subclasses of equimatchable graphs (including ECE-graphs and VCE-graphs) and discuss the properties of factor-critical ECE-graphs with connectivity at least 3. © The author(s).
Gender representation in children’s programming on Turkish television: A public, private mass media analysis of the popular cartoon, Pepee
(Institute for Education Policy Studies, 2023) Hayırsever, F.
This study was developed to examine the popular cartoon Pepee, which is broadcast on a private TV channel in Turkey, considering gender equality. The results are discussed by comparing them with the results of another study that scrutinizes the broadcast of the same cartoon on a Turkish public TV channel (Kalaycı, 2015). The purpose of this comparison is to determine whether the messages on gender equality/inequality differ in terms of TV channels’ belonging to public and private media corporations and whether the messages are similar or different. The research is designed in a descriptive model and has qualitative research characteristics due to utilizing the document review method. The documents analyzed in the study are audio-visuals, the 30 episodes of the cartoon Pepee which were broadcast on a private television channel. The themes determined by Kalaycı (2015) were used in the collection and analysis of the data. Although the number of gender equality messages were reduced in Pepee’s private media broadcast episodes compared to the public media, they still exist. The results show that women’s and men’s gender roles are considerably homogenized between private and public mass media. The differences are notable but not greatly significant. This is a solidification of the critical literature on both state and private mass media and ideological hegemony. This paper works to analyze scientifically the behavioral characteristics of the characters regarding the development of gender role modelling. It finds that regardless of media company control, consistent themes of female domesticity, and relative passivity and male vocational activity putting them at a relative distance from the nurturing components of home living. While democratic discourses are found in some episodes of the Pepee cartoon that were examined, the opposite practices are also present implicitly. Although the media are conceptually and practically categorized as private and public, the contents of broadcasts of both are shaped in line with the ideology of the “state,” and the continued privatization and homogenization of both social and private space. As digital and social media expand greatly, traditional mass media still hold an important place in social education. If countries advocate a democratic way of life, continued critical evaluation of the expression of mass media is still essential, concerning the process of entertainment and it’s ideological, educational function. © 2023, Institute for Education Policy Studies.
