Objectives: The aims of the present study were (1) to determine ethnic differences in craniofacial
dimensions between Turkish and Saudi populations and (2) to identify possible gender differences
between males and females, based on a sample of untreated young adult subjects with
normal occlusions and well-balanced faces.
Methods: In total, 163 cephalometric radiographs were traced and evaluated to compare
untreated adults of Turkish and Saudi ethnicity. The Turkish group comprised 86 subjects; 45
females and 41 males. The Saudi group comprised 77 subjects; 39 females and 38 males. For st ...Daha fazlası
Horizontal root fractures are rare in comparison to other types of injuries and the reported
prevalence in the literature is between 0.5% and 7%. The treatment and prognosis of root
fractures depend on many variables, the most important being the length of time between trauma
and treatment, degree of dislocation and mobility, site of fracture, fixation period, stage of root
development, age of patient, and quality of treatment. The ideal healing type is hard tissue healing.
The aim of these case reports is to present four different patients who had horizontal root fractures
of imma ...Daha fazlası
Coiling of the artery is a rare morphologic entity most frequently described in the internal carotid artery. Herein we present two cases with symptomatic kinked internal carotid artery: one suffering from paresthesia of the right arm and speech disturbances and the other suffering from weakness of the left half of the body and speech disturbances. Both patients were treated surgically. None of the patients experienced any peri- or postoperative complications.
Global crises are increasing day by day due to the rapid depletion of energy supplies around the planet. One of the goals of engineering is to prevent this situation by developing innovative solutions to this rapid energy consumption that has disappeared in the world. A solution could be to reduce the energy consumption of the machines that are used during production. In this study, a new design technique based on the neuro-regression approach and non-linear regression modeling was offered as an alternative to Taguchi design to reduce energy consumption. Thus, a cutting parameter optimization ...Daha fazlası
Abstract In this study, machine learning-based models have been used to estimate the return loss parameters of the operational resonant frequency of the U-slotted UHF RFID antenna. The data set utilized, consisting of 544 instances, has been collected from the simulation software as a consequence of the parametric evaluation of the antenna design parameters. Distinct machine learning methods have been used on two different types of output data, complex and linear scattering parameters, and the models' prediction performance has been evaluated. In the single-output regression models, a mean-squ ...Daha fazlası
On 6th February 2023, two consecutive earthquakes occurred in our country with a magnitude of 7.8 Mw in Kahramanmaras (Pazarcik) and 7.6 Mw in Kahramanmaras (Elbistan). Due to these earthquakes and aftershocks, 48,448 people have lost their lives in Türkiye. A bi-directional and very intense population movement from/to the earthquake area after these earthquakes was observed. Knowing the residence decisions of the disaster victims is important. In the face of the “disaster of the century”, “potential or actual” disaster victims or “pseudo disaster victims”, who exhibit the behavior of disaster ...Daha fazlası
Objective –The aim of this study was to evaluate the effects of local resveratrol
(RSVL) administration on bone formation in response to expansion of the interpremaxillary
suture, in rats.
Material and Methods – Twenty 50- to 60-day-old male Wistar rats were separated
into two equal groups. Both groups were subjected to expansion, and 30 cN of force
was applied to the maxillary incisors with helical-spring. Twenty-four hours after
appliance placement, single-dose 10 lmol ⁄ kg RSVL in the dimethylsulfoxide
(DMSO) was injected to the inter-premaxillary suture in the experimental group. In ...Daha fazlası
Objectives: The aim of this study was to evaluate differences in craniofacial morphology,
head posture and hyoid bone position between mouth breathing (MB) and nasal breathing
(NB) patients.
Methods: Mouth breathing patients comprised 34 skeletal Class I subjects with a mean age of
12.8 ± 1.5 years (range: 12.0–15.2 years). Thirty-two subjects with skeletal Class I relationship were
included in the NB group (mean 13.5 ±1.3 years; range: 12.2–14.8 years). Twenty-seven measurements
(15 angular and 12 linear) were used for the craniofacial analysis. Additionally, 12 measurements
were evalu ...Daha fazlası
Objective: The purpose of this retrospective radiographic study was to determine the reliability and reproducibility of skeletal and
dental measurements of lateral cephalograms created from a computerised tomography (CT) scan compared with conventional
and digital lateral cephalograms.
Methods: CT and conventional lateral cephalograms of the same patients were obtained from university archives. The lateral
cephalometric radiographs of 30 patients were manually traced. The radiographs were subsequently scanned and traced using

Abstract This study is prepared to examine the effects of Turkish character usage on text data by using multiple classifiers. Regression Classifiers, SVM, NB-Classifiers, and ANN are frequently used in supervised learning methods, especially in classification problems. Regression classifiers generally come in two types: as Linear and Logistic. There are also more than one type of Naive Bayes classifier. In our study, after mentioning the properties of Linear Regression and Logistic Regression classifiers in general terms, why Logistic Regression is much more suitable for this study is explaine ...Daha fazlası
Evaluating the fundamental components of traditional Turkish music, particularly the concepts of "usul" (rhythmic composition) and "makam" (musical mode), as well as their significance in the composition and performance of works, has been a focus not only in musical practice but also in academic music studies. Nevertheless, certain issues pertaining to the functional analysis of rhythms, especially the larger rhythmic cycles, such as what they inherently represent in musical reality, how they are utilized, comprehended, and what roles they play in the composition and performance processes, hav ...Daha fazlası
Wire electrical discharge machining (WEDM) of γ titanium aluminide is the subject of the current research. Due to the large number of process variables and sophisticated stochastic process mechanisms, selecting the best machining parameter combinations for increased cutting efficiency and accuracy is a difficult task in WEDM. In general, there is no perfect combination that can produce the fastest cutting speed and the finest surface finish quality at the same time. For this purpose, the data were selected from a literature study. This study describes an attempt to devise a suitable machining ...Daha fazlası
