Fe3O4 nanofluid fully developed forced convection inside a copper tube is empirically investigated under the effect of a magnetic field. All of the investigations are performed under laminar flow regime (670≤Re≤1700) and thermal boundary conditions of the tube with uniform thermal flux. The tube is under the effect of a magnetic field in certain points. This research aims to study the effect of...

Solutions to low energy string theory describing black holes and black strings are reviewed. Many of these solutions can be obtained by applying simple solution generating transformations to the Schwarzschild metric. In a few cases, the corresponding exact conformal field theory is known. Various properties of these solutions are discussed including their global structure, singularities, and Ha...

OBJECTIVE To examine if host baseline factors and week 24 mycology results are associated with mycological and clinical cure in patients with onychomycosis treated with oral terbinafine. DESIGN Open pilot study to determine prognostic factors in the treatment of onychomycosis. SETTING Outpatient dermatology clinic. PATIENTS A total of 199 patients from the Icelandic arm of a trial compari...

OBJECTIVE To correlate losses of retinal thickness in the perifoveal area in glaucoma as measured by the Retinal Thickness Analyzer (Talia Technology Ltd, Israel) with optic nerve and visual field changes in glaucoma patients and suspects. METHODS Observational case series of 55 consecutive patients from the Glaucoma Service who either presented with a diagnosis of glaucoma or were referred f...

PURPOSE To compare learning effect of Swedish interactive threshold algorithm (SITA) standard strategy with full threshold testing. METHODS Thirty-nine medical students with no experience in visual field testing had full threshold (FT) and SITA standard for either right or left eyes. They were chosen in such a way that 20 (Group I) had FT for right and SITA for left eyes and 19 (Group II) had...

PURPOSE To determine which measures of the binocular visual field correlate best with the patient's assessment of vision. METHODS Esterman binocular visual field testing and four other binocular visual field tests (designated peripheral 20 dB [p20], peripheral 22 dB [p22], central 24 dB [c24] and central 26 dB [c26]) were performed in 101 patients with glaucoma or suspected glaucoma. Scores f...

PURPOSE To validate the performance of a new perimetric algorithm (Gradient-Oriented Automated Natural Neighbor Approach; GOANNA) in humans using a novel combination of computer simulation and human testing, which we call Artificial Scotoma Generation (ASG). METHODS Fifteen healthy observers were recruited. Baseline conventional automated perimetry was performed on the Octopus 900. Visual fie...

The Matrix is the latest generation Frequency-Doubling Technology (FDT) perimeter, introduced to the eye care professions in 2003. With seven tests available, visual field testing can proceed from the macula to an eccentricity of thirty degrees. Its ability to detect magnocellular pathway deficiencies has made FDT an excellent tool in the management of glaucoma. The purpose of this article is t...

PURPOSE The aim of this study was to compare an automated confrontation visual field testing (ACV) device with traditional finger-counting confrontation visual field testing (FCV). METHODS Forty-five eyes of 45 subjects with glaucoma, 5 eyes of 5 subjects with neurologic disease and 15 eyes of 15 normal subjects (age matched to the subjects with glaucoma by frequency) were tested on both ACV ...

According to self-determination theory (SDT), need-supportive teaching positively influences students’ engagement to learn. Need-supportive teaching involves teachers providing students with structure, autonomy support, and involvement. It enables teachers to support students’ psychological needs to feel competent, autonomous, and related. Supporting students’ needs consequently has a positive ...
