Ethnic differences in dentofacial relationships of Turkish and Saudi young adults with normal occlusions and well-balanced faces

TANCAN UYSAL

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

Treatments of horizontal root fractures: four case reports

EBRU KÜÇÜKYILMAZ

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

Influence of soft drinks on dental enamel: An in vitro study

EBRU KÜÇÜKYILMAZ | | | |

This in vitro study was to evaluate the erosive potential of four soft drinks at different times on bovine teeth by profilometry. Bovine incisors buccal side was sectioned with a diamond saw and a total of 100 enamel blocks were prepared (8 × 4 × 0.5 mm). Five specimens each were exposed to 60 ml of soft drinks (Sprite, Coca Cola, Cappy-orange and Ayran) for 15, 30, 60, 120 and 180 minutes in a continuously vibrating soft drinks bath in a beaker at room temperature. Surface loss of the specimens was determined with a profilometry. The data were analyzed by two-way analysis of variance and Tuke ...Daha fazlası

Spastik çocuklar Demeği Isparta şubesine başvuran 55'i kız, 60'ı erkek toplam 115 sercbral palsili (SP) basta çalışmaya alındı. SP nedeni olarak bulduğumuz doğum öncesi faktörler: mikrosefalı (%4), ikiz eşi (%4), gebelikte ilaç kullanımı (%2), maternal enfeksiyon (%2). ailede SP öyküsü (%2) ve diabetik anne (%1) idi. Doğum sırası etkenler içinde en sık rastlanan: %37 ile doğum asfiksisi olup bunu %14 ile düşükgestasyonelyaş ve ağırlık ve %3 ile sûrmatürite izlemekteydi. SP'nin doğum sonrası nedenleri olarak da hastalarımızın %7'sinde hiperbiluribinemi. %5'inde ateşli hastalık öyküsü, %3'ünde k ...Daha fazlası

Surgical Treatment Of Symptomatic Coiling Or Kinking Internal Carotid Artery

GALİP AKHAN | ALİ GÜRBÜZ | LEVENT YILIK

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.

A Novel, Nelder-Mead Optimization Approach, based on Neuro-regression modeling for the Energy Efficiency Parameters of End Milling Process

ŞEYDA İŞBİLİR

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

Electron Beam Welding (EBW) of Aerospace Alloy (Inconel 825): Optimization and Modeling of Weld Bead Area

LEVENT AYDIN

This study investigates the optimum weld area on a popular aerospace alloy (i.e., Inconel 825) made by the electron beam welding technique. Welding speed (S), beam current (I), accelerating voltage (V), and beam oscillation (O) are considered as process parameters to study the weld bead area (WA) of the weldments. An instructive study on multiple non-linear neural regression analyses has been done as a basic introduction to neuro regression modeling with artificial neural network (ANN) philosophy. To do this, the experimental prediction has been modeled with 14 predictive functional structures ...Daha fazlası

Estimation of Scattering Parameters of U-Slotted Rectangular RFID Patch Antenna with Machine Learning Models

İsmail AKDAĞ

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

İmâmiyye Şîası’nda İlelü’l-Hadîs İlmi ve Zayıf Hadisle Münasebeti

İbrahim Kutluay

Zâhiren sahih görünen hadisin isnad ya da metnindeki inkıta, irsal, tedlîs, idrac, iklab, teâruz, tashîf gibi gizli ve kapalı kusurları inceleyen bir ilim olan ilelü’l-hadîsin, hadis ilimleri içinde önemli bir yeri bulunmaktadır. Bu ilimde söz sahibi olabilmek için hadis râvilerinin hâllerine, isnadlara ve hadis metinlerine vukûfiyetin yanı sıra, güçlü bir hafıza, tecrübe ve uzmanlık gerekmektedir. Erken dönemden itibaren Ehl-i sünnet âlimleri bu ilme ehemmiyet vermiş ve bu alanda kıymetli eserler telif etmişlerdir. Ehl-i sünnet’e nisbetle Şiî ulemânın ilelü’l-hadîs konusuyla daha az ilgilenme ...Daha fazlası

Henry Corbin, Tanrının Yüzü İnsanın Yüzü: Yorumbilgisi ve Tasavvuf, çev. Kübra Gürkan, B. Garen Beşiktaşlıyan

Hermeneutik ve tasavvuf arasındaki ilişki özellikle son dönemde tasavvuf metinlerinin muhtevasını anlama girişimleriyle artmış ve belirginleşmiştir. Birçok çalışmada doğaüstü olarak kabul edilen bu mistik metinlerin yapısı, içinde bulunduğu geleneğin de etkisiyle kapalı kalmış ve ulaşılamadıkça okur için daha da büyük bir ilgi odağı haline gelmiştir. Hermeneutik bir tavırla tasavvuf metinlerine nüfuz edilebileceği düşüncesi ise halen tartışmalıdır.
