OBJECTIVES Typical streak artifacts known as metal artifacts occur in the presence of strongly attenuating materials in computed tomography (CT). Recently, vendors have started offering metal artifact reduction (MAR) techniques. In addition, a MAR technique called the metal deletion technique (MDT) is freely available and able to reduce metal artifacts using reconstructed images. Although a com...
AIMS In Escherichia coli, increased expression of efflux pumps and/or decreased expression of porins can confer multiple antibiotic resistance (MAR), causing resistance to at least three unrelated classes of antibiotics, detergents and dyes. It was hypothesized that in Campylobacter jejuni, the efflux systems CmeABC, CmeDEF and the major outer membrane porin protein, MOMP (encoded by porA) coul...
In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity and biodiversity capable of supporting commercial fisheries. We investigated the origin of this apparent biological enhancement over a segment of the North Mid-Atlantic Ridge (MAR) using sonar, corers, trawls, traps, and a remotely operated vehicle ...
In this paper we present a markerless augmented reality (MAR) approach based on real-time 3D reconstruction using a low-cost depth camera, the Kinect. We intend to use this MAR approach for 3D medical visualization. In the actual state of developing, our approach is based on the KinectFusion algorithm with some minor adaptations, as long as our goal is not reconstruct scenes but use the reconst...
The 5-upstream region of a winged bean chymotrypsin inhibitor gene (JVCI-3b) was found to have a high affinity for nuclear matrix. The region, named WCI-3b MAR (matrix attachment region), is highly A + T-rich and contains multiple sites interacting with nuclear matrix. A MAR was also found in the corresponding region of the WCI-x gene, another active gene of the WCI family. Several MAR-binding ...
INTRODUCTION Serious thrombembolic events occur in otherwise healthy marathon athletes during competition. We tested the hypothesis that during heavy endurance sports coagulation and platelets are activated depending on the type of endurance sport with respect to its running fraction. MATERIALS AND METHODS 68 healthy athletes participating in marathon (MAR, running 42 km, n = 24), triathlon (...
Karin Andersson (2018): Metal Artifacts in Computed Tomography – impact of reduction methods on image quality and radiotherapy treatment planning. Örebro Studies in Medicine 172. Degradation of image quality by metal artifacts is a common problem in computed tomography (CT) imaging, which can limit the diagnostic value of a CT examination and also introduce inaccuracies in radiotherapy (RT) tre...
O presente artigo tem como objetivo analisar o desenvolvimento e a modernização da cidade de Florianópolis, capital Santa Catarina, através das memórias um pescador comunidade periférica Tapera, no sul Ilha Catarina. A partir dos relatos fornecidos por esse privilegiado informante busco reconstituir entender processo sendo responsável pelo afastamento sociabilidades marítimas, elitização espaço...
Depois do 25 de abril 1974 – conhecido como Revolução dos Cravos ou Abril –, que depôs o regime ditatorial “Estado Novo”, uma movimentação profunda, marcada por combinação teatro tradição brechtiana, neorrealista e experimentalismo, foi ganhando espaço para constituir cena permeável a formas menos convencionais. Em sintonia com esse processo criativo, examino trajetória grupo A Barraca (dirigid...
