Biometric data is the key for many security applications. Authentication relies on the individual’s measurable biometric properties collected as features. In this study, a face authentication system is built to be used in opening the entrance door accessing to the apartments and housing estates. The proposed system consists of three stages. In the first stage, landmarks on the face are captured using a deep neural network. Then six selected features from the landmarks are extracted and traditional machine learning algorithms are used to authenticate users. In the last stage, a user interface i ...Daha fazlası
Objective: In this study investigates the effect of the type and volume of solution used in inflation of the foley catheter balloon on the development of urine leakage around the catheter during indwelling urethral catheterization. Material and Method: This randomized controlled experimental study was conducted with 128 patients hospitalized in the intensive care unit and carried out between 2015 and 2019. In each study group, different types and volumes of the solution including 10 mL 0.9% sodium chloride, 15 mL 0.9% sodium chloride, 10 mL sterile distilled water, and 15 mL sterile distilled ...Daha fazlası
Objective: The aim of this study is to compare the side effects of Pfizer-BioNTech mRNA and Sinovac-CoronaVac vaccines administered in adults in Turkey. Material and Method: This is a cross-sectional study. The study sample consisted of 187 adults, 95 in the Pfizer-BioNTech group and 92 in the Sinovac-CoronaVac group, who came for vaccination. A Visual Analogue Scale (VAS) and a questionnaire were applied to vaccinated individuals in a hospital. They were asked about any adverse effects at 6, 12 and 24 hours post-vaccination. Results: The most common local adverse effect was pain at the inject ...Daha fazlası
Introduction: The aim of this study was to determine the peri-miniscrew implant crevicular fluid receptor
activator of nuclear factor-lB ligand (RANKL) and osteoprotegerin (OPG) levels around loaded and unloaded
miniscrew implants at different time intervals. Methods: Twenty loaded and 16 unloaded miniscrew implants
were included in this study. All miniscrew implants were placed bilaterally between the maxillary second premolars
and first molars as anchorage units for canine distalization. Peri-miniscrew implant crevicular fluid was taken
from the mesiobuccal aspects of the loaded and unl ...Daha fazlası
Objective: To study and compare the effects of different demineralizationinhibition
methods on the shear bond strength (SBS) and fracture mode of an
adhesive used to bond orthodontic brackets to demineralized enamel surfaces.
Methods: Eighty freshly extracted, human maxillary premolars were divided
into 4 equal groups and demineralized over the course of 21 days. Brackets were
bonded to the demineralized enamel of teeth in Group 1. In Group 2, bonding
was performed following resin infi ltration (ICON®, DMG, Hamburg, Germany).
Before bonding, pre-treatment with acidulated phosphate fluor ...Daha fazlası
This study was performed to determine the concentrations
of some trace metals (Cd, Cu, Pb, Ni, Zn, and Fe) in
Holothuria tubuosa (Gmelin, 1788) belonging to Echinoderm
species and in sediments that they live at three different stations
(Gelibolu, Umur Bey/Lapseki, and Dardanos) on
Dardanelles Strait between April 2013 and March 2014. The
mean trace metal concentrations determined in H. tubulosa
and sediment were as follows: Cd 0.18 mg/kg, Cu 2.43 mg/
kg, Pb 2.09 mg/kg, Ni 14.58 mg/kg, Zn 16.86 mg/kg, and Fe
73.46 mg/kg and Cd 0.70 mg/kg, Cu 5.03 mg/kg, Pb
14.57 mg/kg, Ni 27.15 mg/kg, ...Daha fazlası
Objective
We evaluated the detachment force, amount of deformation, fracture mode, and pull-out force of 3 different wires used for bonded lingual retainer fabrication.
Methods
We tested 0.0215-inch five-stranded wire (PentaOne, Masel; group I), 0.016 × 0.022-inch dead-soft eight-braided wire (Bond-A-Braid, Reliance; group II), and 0.0195-inch dead-soft coaxial wire (Respond, Ormco; group III). To test detachment force, deformation, and fracture mode, we embedded 94 lower incisor teeth in acrylic blocks in pairs. Retainer wires were bonded to the teeth and vertically directed force was ap ...Daha fazlası

Scorpionfish (Scorpaena porcus) is a demersal fish
species commercially important for its of which meat is tough
and delicious. The aim of this study was to determine heavy
metal (Al, Cu, Ni, As, Cd, Hg, Pb, U) concentrations in this
fish species which is traditionally consumed in the Black Sea
Area and, to compare the concentrations of various toxic elements
in different organs of the fish specimens (muscle, liver,
gill, and skin). Within this scope, the mineralization was performed
using microwave digestion system. Thirty-two scor
pionfish caught from Sinop Inland Port during 2010 w ...Daha fazlası
