Öğe 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.Öğe 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.

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.

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.

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.Öğe 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.Öğe Antioxidant and Apoptotic Effect of Edaravone on Cisplatin-Induced Brain Injury in Rats(Neurological Society R.O.C (Taiwan), 2024) Kara, O.; Kilitci, A.Purpose: This study aims to investigate the effect of edaravone in preventing cisplatin-induced brain damage. Methods: Forty female Wistar albino rats were included in the study. 4 groups were created. In group 1 (control group) (n=10), neither any drugs were given nor anything was performed. Group 2 (cisplatin group) (n=10), single dose 7.5 mg/kg cisplatin was given. In group 3 (edaravone group) (n=10), single dose 1 mg/kg edaravone was administered. Group 4 (cisplatin+ edaravone group) (n=10), single dose 7.5 mg/kg cisplatin and 1 mg/kg edaravone were given. Brain tissue was removed in all rats after 3 days. Blood samples taken from heart tissue were examined for malondialdehyde (MDA) and nitric oxide (NO) levels. Brain tissue was evaluated for damage with p53, GFAP and Ki 67. Results: Edaravone reduced cisplatin-induced brain damage. MDA and NO levels in the cisplatin group were significantly higher than the other groups (p< 0.05). Likewise, tissue damage in the cisplatin group was significantly higher than in the other groups (p< 0.05). The immunohistochemical staining which was done by using p53, GFAP and Ki 67 was shown that tissue damage was higher in cisplatin group than cisplatin+ edaravone group and this difference was found to be statistically significant (p< 0.05). Conclusion: The findings of our study suggest that edaravone therapy may be effective in the prevention and treatment of cisplatin-induced brain injury. © 2024, Neurological Society R.O.C (Taiwan).

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.

In this sense, this study aims to investigate i) whether listening skills are considered as important as the other receptive and productive skills, ii) EFL teachers' perspectives on motivation levels of learners towards listening in the target language, iii) whether teachers feel competent enough to teach listening skills, and iv) whether listening skills are evaluated in EFL classes. The participants of the study consisted of 45 teachers, and the data were gathered through a semi-structured interview form which was prepared by the researchers. The findings reveal that teaching listening skills is mostly ignored in Turkey, teachers believe that learners have low motivation while learning listening skills in English, and most of the teachers who participated in the study feel competent in teaching listening skills; however, in teaching and testing listening, they have some concerns. Lastly, the findings reveal that testing listening skills are mostly ignored in Türkiye. © 2023 The Author(s).Öğe Fractional Milne type inequalities(Comenius University in Bratislava, 2024) Budak, H.; Karagözoğlu, P.In the literature, there are several numerical integration formulas and many researchers have been investigating the error bounds of these formulas for several function classes such as convex functions, bounded functions, Lipschitzian functions, functions of bounded variation, etc. In this research article, we obtain some Milne type inequalities to the case of Riemann–Liouville fractional integrals by means of some important function classes.

The obesity (ob) gene regulates leptin hormone release, which plays a role in body fat regulation. Obesity, which is defined by a rise in blood leptin levels, is a key risk factor for cardiovascular disease. Because of the increased activity of the sympathetic nervous system and the accompanying renin-angiotensin system, obesity produces a rise in extracellular fluid volume. The increase in sympathetic activity caused by hyperleptinemia is one of the reasons for obesity-related hypertension. One of the reasons for cardiovascular diseases in obesity is the interplay of angiotensin II, insulin, endothelin-A, and hyperleptinemia. Acute cardiovascular events, restenosis following coronary angioplasty, and cerebral palsy have all been linked to high leptin levels. In leptin-deficient mice, arterial thrombosis was shown to be minimal. As a result, inhibiting leptin activation could be a future therapy method for hyperleptinemic obese people to reduce the course of atherosclerosis. This book chapter will discuss the consequences of hyperleptinemia caused by high leptin serum levels and leptin receptor resistance in obesity on renal, cardiac, vascular, and sympathetic nervous system function, as well as their relationship to cardiovascular disease. © 2024 by Nova Science Publishers, Inc.

The material recovered from the structures of the theatre and the monastery makes it possible to assess the extent of the Mediterranean Basin pottery trends as reflected in the city in the Late Antique period. In this context, it can be determined that the importation of Late Roman Red Slip wares, which began to appear from the middle of the 5th century AD in Olba, continued until the end of the 7th century AD. The Phocaean Red Slip Ware seen in the city from the middle of the 5th century AD was followed by Light Coloured Ware dating to the middle of the 6th century. Phocaean Red Slip Ware, which from the first half of the 6th century AD had again gained importance, was in demand until the middle of 7th century AD. This pottery was followed by African Red Slip Ware and Cypriot Red Slip Ware from the middle of the first half of the 6th century AD. © the individual authors and Archaeopress 2023.

The genesis of behavioral disorders is influenced by several elements as a result of this complicated relationship. Because hormones are so tightly linked to the brain and nervous system, behavioral issues might be hormonal. Because of receptor insensitivity, the number of hormones may drop or rise; the number of receptors may alter; and mutations may develop. Leptin is a hormone that is generated mostly by fatty tissue, although it can also be produced by the placenta, skeletal muscle, stomach, mammary epithelium, and brain tissue. The hypothalamus, one of the body's most important organs, regulates the hormone leptin's physiological role and systemic effect. The leptin hormone inhibits appetite while increasing energy consumption in the hypothalamus arcuate nucleus. Leptin has been shown to have both peripheral and central effects, interacting with the endocrine system and hence possibly impacting behavior. Eating disorders, schizophrenia, sleep, sexual behavior, depression, anxiety, anorexia nervosa, bipolar illness, borderline personality disorder, and alcohol use disorders have all been connected to leptin. According to studies, leptin has been linked to several behavioral illnesses, including depression. Furthermore, the interaction of antidepressants and antipsychotics with the hormone leptin has emerged as a new topic of research. The role of leptin in neurological and behavioral diseases is emphasized in this book chapter. The chapter discusses many features of leptin and emphasizes the significance of future research to better understand leptin's involvement in disease causes and therapy. © 2024 by Nova Science Publishers, Inc.

The species overwinters at the egg stage and has two generations per year. The number of host plants identified in this study is 57 (belonging to 31 families). With previous studies, the number of host plant species in Türkiye has reached 58. The main host plants were Ligustrum lucidum W. T. Aiton and Olea europaea L. Eggs are laid in double rows in the thin twigs of shrubs or trees of one-year old, exceptionally in the main vein on the lower leaf surface of Magnolia grandiflora L. The mean number of eggs laid on L. lucidum and O. europaea were 31.88 and 21.80, respectively. Mean length of egg masses was 17.90 and 15.36 mm and mean twig thickness was 2.21 and 2.20 mm, respectively, on L. lucidum and O. europaea. Zelus renardii (Hemiptera: Reduviidae) was identified as a predator of P. shantungensis. © 2023 Bulgarian Academy of Sciences.

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).Öğe The late effects of carbon monoxide poisoning(Nova Science Publishers, Inc., 2023) Sultanoğlu, H.; Yartaşi, Y.H.; Kara, A.C.Carbon monoxide is a highly toxic gas for humans, which is formed as a result of the incomplete combustion of carbon-based fuels. It is a difficult gas to detect due to its non-irritant and high diffusion capacity. That is why it is called the "silent killer". While there are complaints of headache, nausea, vomiting, dizziness, and shortness of breath in the acute phase of carbon monoxide poisoning, cardiac ischemic problems, muscle weakness, decreased attention, confusion, convulsions, paralysis, and coma may develop in the chronic period as exposure and severity increase. CO poisoning still remains important because of its mortal course and the fact that it occurs in different people in different ways and at different times, causing difficulties for physicians in the diagnostic process. Although the current technological possibilities are advanced, the suspicion that occurs in the minds of doctors after a good anamnesis is more important than all other methods. The good clinical course of diagnosed patients in the acute period should not mislead doctors. It should be kept in mind that cardiac and neurological findings may occur in the late period and patients should be followed up regularly. © 2024 Nova Science Publishers, Inc.

The growing interest for magnesium alloys in the field of bioabsorbable osteosynthesis devices is because they simultaneously fulfil the needs of biocompatibility and superior mechanical performance compared to biodegradable polymers. Weight loss tests were carried out for different exposure times in aerated isotonic solution (0.9% NaCl) at 37 °C. The results obtained showed excellent corrosion resistance of alloy WE43B compared to the other analyzed materials. Otherwise EV31A alloy exhibited numerous localized attacks, although showing lower weight loss than commercially pure magnesium. Alloy WE43B has a constant dissolution rate over the exposure time, whereas alloy EV31A and commercially pure magnesium exhibit a rate of corrosion that decreases over time due to the strong alkalinization of the solution and the deposition of a thick layer of corrosion products. © 2023 Associazione Italiana di Metallurgia.
