Nanotechnology and earth construction: the mechanical properties of adobe brick stabilized by Laponite nanoparticles

2014

The contribution describes the experimental analysis for the improvement of the mechanical properties of samples of earth with the addition of Laponite nanoparticles. Were made two types of samples: the first consisting of soil, sand and water; the second consisting of soil, water, sand and Laponite nanoparticles. The operations performed were: chemical analysis of soil and sand; preparation of samples; Scanning Electron Microscope (SEM) observation of samples for the distribution of the elements, especially the Laponite nanoparticles; testing of compression strength and flexural strength of two types of samples; comparisons of the resulted of the mechanical tests. The improvement of the me…

Multicenter, double-blind, randomized, intraindividual crossover comparison of gadobenate dimeglumine and gadopentetate dimeglumine for Breast MR ima…

2011

To intraindividually compare 0.1 mmol/kg doses of gadobenate dimeglumine and gadopentetate dimeglumine for contrast material-enhanced breast magnetic resonance (MR) imaging by using a prospective, multicenter double-blind, randomized protocol.Institutional review board approval and patient informed consent were obtained. One hundred sixty-two women (mean age, 52.8 years ± 12.3 [standard deviation]) enrolled at 17 sites in Europe and China between July 2007 and May 2009 underwent at least one breast MR imaging examination at 1.5 T by using three-dimensional spoiled gradient-echo sequences. Of these, 151 women received both contrast agents in randomized order in otherwise identical examinatio…

Focal nodular hyperplasia: a weight-based, intraindividual comparison of gadobenate dimeglumine and gadoxetate disodium-enhanced MRI

2019

PURPOSE: We aimed to qualitatively and quantitatively compare the enhancement pattern of focal nodular hyperplasia after gadobenate dimeglumine and gadoxetate disodium injection in the same patient. METHODS: 1.5 T magnetic resonance imaging (MRI) examinations of 16 patients with 21 focal nodular hyperplasias studied after the injection of both contrast media were evaluated. Both MRI studies were performed in all patients. A qualitative analysis was performed evaluating each lesion in all phases. For quantitative analysis we calculated signal intensity ratio, lesion-to-liver contrast ratio and liver parenchyma signal intensity gain on hepatobiliary phase. Statistical analysis was performed w…

Effect of posterior gingival smile on the perception of smile esthetics

2013

Objectives: To evaluate and compare the influence of posterior gummy smile on the perception of smile esthetics by orthodontists, general-dentists and laypersons. Study Design: A frontal photograph of a smile with normal gum exposure was chosen and manipulated digitally using Adobe Photoshop C3 to generate three further images with posterior gum exposure of 4, 6 and 8mm. These four images were assessed by the three evaluator groups: orthodontists (n=40), general-dentists (n=40) and laypersons (n=40). Both orthodontists and dentists had at least ten years professional experience and laypersons were aged between 40-50 years. The proportion of men to women was 20:20 in each group. Evaluators a…

Diagnostic performance of gadobenate dimeglumine enhanced MR angiography of the iliofemoral and calf arteries: a large-scale multicenter trial

2007

OBJECTIVE. The purpose of this study was to compare gadobenate dimeglumine–enhanced MR angiography and unenhanced time-of-flight MR angiography for the detection of significant peripheral arterial occlusive disease using digital subtraction angiography as our reference standard. SUBJECTS AND METHODS. Two hundred seventy-two patients underwent MR angiography and digital subtraction angiography of the iliofemoral arteries. MR angiography was performed before (2D time-of-flight acquisitions) and after (spoiled gradient-echo acquisitions) the administration of 0.1 mmol/kg of gadobenate dimeglumine at 1–2 mL/s. Contrast-enhanced MR angiography and digital subtraction angiography of the calf arte…

MR angiography of the pedal arteries with gadobenate dimeglumine, a contrast agent with increased relaxivity, and comparison with selective intraarte…

2007

Purpose To compare gadobenate dimeglumine (Gd-BOPTA)–enhanced MR angiography (i.e., contrast-enhanced MRA [CE-MRA]) of the pedal vasculature with selective digital subtraction angiography (DSA) in patients with peripheral arterial occlusive disease (PAOD). Materials and Methods A total of 22 patients with PAOD were prospectively examined at 1.5T. For contrast enhancement, 0.1 mmol/kg body weight of Gd-BOPTA were applied. MRA consisted of dynamic imaging with acquisition of six consecutive data sets. Acquisition time for each data set was 24 seconds, voxel size was 1.0 × 1.0 × 1.3 mm3. A total of 20 out of 22 patient underwent selective DSA, two patients fine-needle DSA. DSA and MRA were per…

HTML5 un Adobe AIR hibrīdo mobilo lietotņu izstrādes salīdzinājums

2015

Mobilo lietotņu tirgus ir plašs un ar katru nākamo gadu lietotņu skaits strauji pieaug. 2014. gadā 80% pasaules iedzīvotāju bija vismaz viens viedtālrunis. Bakalaura darbā ir veikts HTML5 un Adobe AIR hibrīdo mobilo lietotņu izstrādes platformu salīdzinājums. HTML5 izstrādes pieeja ir lietotņu izstrāde, izmantojot tīmekļa pārlūku, bet Adobe AIR izstrādes pieeja veic kompilāciju no augsta līmeņa programmēšanas valodas uz dzimtās platformas zema līmeņa valodu – bitkodu. Abas mobilo lietotņu platformas tika salīdzinātas pēc Henning Heitkötter vairākplatformu salīdzinājuma kritērijiem. Gala rezultātā tika izveidota mobilā lietotne priekš HTML5 un Adobe AIR izstrādes platformām un veikti platfor…

Comparison of digital protocols for the measurement of peri-implant marginal bone loss

2018

Background The measurement of peri-implant marginal bone loss is currently carried out using digital methods of radiographic analysis assisted by various types of software. The purpose of this study was to compare the characteristics of three different softwares: specific radiology software for the development and visualization of radiological images in DICOM format (3Dicom Viewer®), advanced level software for professional editing of bitmap images (or raster graphics) (Adobe Photoshop®), and mid-level software for processing bitmap-type images, programmed in Java and in the public domain (ImageJ®). Material and Methods It was verified that the three softwares used are valid for the measure…

Earth Construction: The Mechanical Properties of Adobe with the Addition of Laponite

2015

The contribution describes testing of compression strength, flexural strength and abrasion resistance of adobe made up of soil, water and sand (AS), soil, water, sand and straw (ASP), soil, water, sand and laponite nanoparticles (ASN). Embodied energy in materials presents an increasingly high percentage of the energy spent in the whole life cycle of a building. The same applies for carbon dioxide (CO2). Therefore, the development of new sustainable construction materi- als with lower embodied energy and lower CO2 emissions is needed. The use in construction of the brick made from soil, water and sand or straw, called adobe, boasts a millenary tradition and in recent years there has been re…
