Slip distribution of the 2017 M(w)6.6 Bodrum-Kos earthquake: resolving the ambiguity of fault geometry

SUMMARY The 2017 July 20, Mw6.6 Bodrum–Kos earthquake occurred in the Gulf of Gökova in the SE Aegean, a region characterized by N–S extension in the backarc of the easternmost Hellenic Trench. The dip direction of the fault that ruptured during the earthquake has been a matter of controversy where both north- and south-dipping fault planes were used to model the coseismic slip in previous studies. Here, we use seismic (seismicity, main shock modelling, aftershock relocations and aftershock mechanisms using regional body and surface waves), geodetic (GPS, InSAR) and structural observations to estimate the location, and the dip direction of the fault that ruptured during the 2017 earthquake, and the relationship of this event to regional tectonics. We consider both dip directions and systematically search for the best-fitting locations for the north- and south-dipping fault planes. Comparing the best-fitting planes for both dip directions in terms of their misfit to the geodetic data, proximity to the hypocenter location and Coulomb stress changes at the aftershock locations, we conclude that the 2017 earthquake ruptured a north-dipping fault. We find that the earthquake occurred on a 20–25 km long, ∼E–W striking, 40° north-dipping, pure normal fault with slip primarily confined between 3 and 15 km depth, and the largest slip exceeding 2 m between depths of 4 and 10 km. The coseismic fault, not mapped previously, projects to the surface within the western Gulf, and partly serves both to widen the Gulf and separate Kos Island from the Bodrum Peninsula of SW Anatolia. The coseismic fault may be an extension of a mapped, north-dipping normal fault along the south side of the Gulf of Gökova. While all of the larger aftershocks are consistent with N–S extension, their spatially dispersed pattern attests to the high degree of crustal fracturing within the basin, due to rapid trenchward extension and anticlockwise rotation within the southeastern Aegean

Laser Ablation Inductively Coupled Plasma Mass Spectrometry U-Pb Dating of Detrital and Magmatic Zircons of Glacial Diamictites and Pebbles in Late Ordovician Sediments of the Taurides and Southeast Anatolian Autochthon Belt, Turkey: Indications for Their Arabian-Nubian Provenance

Late Ordovician (Hirnantian) glacio-marine deposits in the Central and Eastern Taurides and Southeast Anatolian Autochthon Belt (SAAB) in Turkey are mainly composed of diamictites, subrounded granitic pebbles, and rounded/subrounded lonestone pebbles. The granitic pebbles are dated as 576.5 ± 3.3, 576.7 ± 5.7, 598.4 ± 7.5, 717.5 ± 8.0, 789.5 ± 3.7, and 964.6 ± 4.6 Ma. The geochemical signatures and dated granitic pebbles in the Central and Eastern Taurides are interpreted to have been derived from the Late Neoproterozoic granitoids/metagranitic rocks of the Arabian-Nubian Shield (ANS; the Sinai Peninsula and the Eastern Desert of Egypt). The youngest 206Pb/238U ages in the diamictites (499.1 ± 4.2 Ma in the SAAB, 530.5 ± 5.3 Ma in the Eastern Taurides, and 562.5 ± 5.4 Ma in the Central Taurides) and in the lonestones (528.2 ± 4.5 Ma in the Central Taurides, 530.8 ± 5.2 Ma in the Eastern Taurides) indicate that detrital zircons were directly transported mainly from the northern margin of Gondwana and/or Arabia during the Late Ordovician, not from peri-Gondwanan parts of the European margin. Kernel/probability density diagrams of zircon ages from the lonestone pebbles in the Eastern and Central Taurides are interpreted as evidence for their derivation from Late/Middle Cambrian siliciclastic rocks in the Israeli part of the Sinai Peninsula. The provenance of detrital zircon populations in the diamictites in the Central and Eastern Taurides is directly correlated with magmatic activity of the Elat (Taba)–Feiran island arc, the Sa’al island arc, and the postcollisional magmatic suites in the Sinai Peninsula (Egypt). However, the corresponding successions in the SAAB have more abundant Late Cryogenian age components, suggesting the Ha’il/Afif/Ad Dawadimi/Ar-Rayn terranes of the eastern Arabian Shield as their provenance. These distinctive age patterns indicate that glacio-marine successions in the SAAB had different paleogeographic positions than their equivalent units in the Central and Eastern Taurides during deposition of the Late Ordovician glacio-marine units

Novel nanofibre integrated SiN scaffolds for skeletal implant applications

Nowadays, increase in number of orthopedic surgery accelerates global interest in the world orthopedic industry. Apart from the increased number of the surgery, the rapid recovery becomes very important following the initial operations. One of the common problem for the patients is the biocompatibility between the implant and tissue [1-3]. In this study, we aimed to improve attachment of the implant to the tissue in addition to provide high biocompatibility. After preparing a scaffold by using SiN subsequently we have coated with fine gelatine nanofibers. SiN is one of the most commonly used bioactive ceramic class, and also its biocompatibility is good enough

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%.Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespa

Chemokine induction by pneumococcal proteins in human nasopharyngeal epithelial cells

Streptococcus pneumoniae naturally resides in the nasopharynx of colonised individuals. Although nasopharyngeal colonisation is asymptomatic it is the first step toward pneumococcal disease. Elucidating the mechanisms by which S. pneumoniae stimulates the mucosal innate immune response may help us understand the progression from asymptomatic colonisation to inflammatory disease.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

The Relationship Between Balance Disorders and Lung Involvement in COVID-19 Patients

Introduction: To better understand COVID-19 and prevent the spread of the disease, symptoms associated with COVID-19 should be known. The list of symptoms of COVID-19 is expanding. This study aimed to examine the relation between balance disorders and radiologically detected lung involvement seen in COVID-19 patients. Materials and Methods: This cross-sectional study was conducted in Cerrahpasa School of Medicine Hospital and Cerrahpasa Medicine Faculty between July 2021 to June 2022. The study included 174 COVID-19 patients with pulmonary involvement (Group 1) and 174 COVID-19 patients without pulmonary involvement (Group 2). Balance disorders of the patients within one month after the diagnosis of COVID-19 were questioned with a self-reported questionnaire made over the phone. The incidence of balance disorders, type of balance disorder, onset time, duration, and severity were questioned. Results: Balance disorders were detected in 67 (19.3%) of the patients. Dizziness was detected in 60 (89.55%) of these patients, and vertigo was detected in seven (10.45%) of them. The number of patients with balance disorders was 49 (28.2%) in Group 1 and 18 (10.3%) in Group 2. The frequency of balance disorders was significantly higher in Group 1 (p= 0.001). Vertigo was detected in in (3.4%) and dizziness in 43 patients (24.7%) in Group 1, and vertigo was detected in one patient (0.6%) and dizziness in 17 patients (9.8%) in Group 2. The frequency of dizziness was significantly higher in Group 1 (p= 0.001). Balance disorders were significantly longer and more severe in Group 1 (p= 0.048, p= 0.029, respectively). Conclusion: Balance disorders can be a symptom of COVID-19, and they may be more frequent, more serious, and longer lasting in patients with pulmonary involvement

Parent-school collaboration based on the frequency of visits to their child's school

This study examines parent-school collaboration in primary schools. School administrators, teachers, and parents are the stakeholders of the school, together with the students. Coordinated and harmonious work by all stakeholders increases the success of the school. The family plays an important role in raising a child, and the importance of collaboration between school and family is increasing day by day. Therefore, we expect parents to collaborate with teachers and school administrators in this process. The sample consists of 336 primary school parents randomly selected from 4 schools in Edirne, Turkey. We used the "parent-school collaboration scale" to collect research data. The scale contains 30 items and 5 subscales. ANOVA (Analysis of variance) was used in the analysis of the data, and in cases where the difference between population means was significant, LSD (the least significant difference) test statistical techniques were used to determine the source of the difference. Interdimensional relationships were determined by the Pearson correlation coefficient technique. There is a recursive relationship between the parents' collaborative attitude and their communication with the school. If the level of communication between parents and other stakeholders in the school increases, the attitude towards collaboration with the school will also be more positive. According to the research findings, the importance of parents sharing information about their children is emerging
