Videofluorography swallow study of patients with systemic sclerosis

2009

PURPOSE: This study was undertaken to evaluate the role of the videofluorographic (VFG) swallow study in patients with systemic sclerosis. MATERIALS AND METHODS: Over a 23-month period, 45 women (mean age 58 years, range 27-76 years) with a known diagnosis of systemic sclerosis and a history of dysphagia underwent a dynamic and morphological study of the oral, pharyngeal and oesophageal phases of swallowing with videofluorography. All examinations were performed with a remote-controlled digital C-arm device with 16-in image intensifier, 0.6- to 1.2-mm focal spot range and maximum tube voltage of 150 kVp in fluorography and 120 kVp in fluoroscopy. Cineradiographic sequences were acquired for…

Projekts: Autoservisa dibināšana.

2021

Maģistra darba “Projekts: Autoservisa dibināšana” ideja ir izveidot neautorizēto vieglo automašīnu servisa centru Pierīgā, kas nodrošinās pilna spektra servisa pakalpojumu automašīnām, kurām ir beigusies rūpnīcas garantija. Jaundibinātais uzņēmums būs daļa no uzņēmumu grupas, kurai pieder vairāki autorizētie servisi un automašīnu dīleri visās trīs Baltijas valstīs, tas pieteiks sevi pagaidām vēl neapgūtā tirgus nišā uzņēmumu grupā – serviss automašīnām pēc garantijas periodā, nodrošinot servisa pakalpojumu visa automašīnas dzīves cikla garumā vienā uzņēmumu grupā. Uzņēmums fokusēsies galvenokārt uz Volkswagen (VW) markas un VW grupā ietilpstošo marku automašīnu apkopi.

A Risk-Based Approach for Mitigating Ethical Lapses

2019

In early 2008, the CEO of Volkswagen announced a 10-year plan that called for tripling the company’s U.S. sales by 2018. The executive gave marching orders to engineers to come up with a new technology that would enable VW to lower emissions of the new cars. The engineers failed to come up with a device that could do the job. Instead they deployed a defeating software would defeat the testing process. The 2009 VW Jetta clean diesel was launched in April 2008 and followed by the introduction of similarly equipped VW Golfs and Audi A3s. Over 145,000 vehicles were sold in the U.S. in three years. The scheme was eventually exposed, costing the company millions of dollars. This paper describes t…

Die nonverbale Kommunikation im Video der Markenkampagne ‚Partner fürs Leben' von Volkswagen

2018

Tämä kandidaatintutkielma käsittelee nonverbaalista viestintää Volkswagenin mainoskampanjan ‚Partner fürs Leben’ videossa. Kampanja on peräisin vuodelta 2016 ja sen taustana on vuoden 2015 päästöskandaali, jonka vuoksi Volkswagenin maine laski hurjasti. Pelastaakseen maineensa, Volkswagen-konserni aloitti suuren mainoskampanjan, jossa huomion keskipisteenä ensimmäistä kertaa Volkswagenin mainoshistoriassa on ihminen, eikä auto. Kampanjan tarkoituksena on kertoa, että Volkswagenin autot ovat ikään kuin perheenjäseniä, jotka tukevat kuluttajaa hänen koko elämänsä ajan, ja tärkeimpänä vaikutuskeinona tässä yhteydessä käytetään nonverbaalista viestintää. Tutkielmassa keskitytään mainoskampanjan…

Preliminary study on analysis and removal of wax from a Carrara marble statue

2015

This preliminary study has mainly focused on the wax identification by nuclear magnetic resonance (NMR) and removal. Wax is used for many purposes in the field of art as protective coatings on wooden, stone or metal objects. From the comparison of the spectra H NMR and in particular with the correspondence of the resonance peaks of the samples taken from the statue and beeswax and paraffin, we can conclude that the wax applied on the statue surface is beeswax. From our data, it can be concluded that, to remove the beeswax, from any stone support, the more effective solvent is the mixture of cyclohexane/ethyl acetate. The removal percentages ranged from 19 to 99%. Lower percentages of remova…

Food supplementation reveals constraints and adaptability of egg quality in the magpie Pica pica

2015

Differences in the deposition of limited maternal resources to eggs can reflect the optimal allocation to manipulate offspring phenotype, or constraints caused by maternal condition. We examined multiple maternal substances transferred to eggs in the magpie Pica pica to test the hypothesis that certain substances represent constraint and some optimal allocation. We did this by supplementary feeding magpies prior to egg-laying and then comparing the effect of food on maternal substances in conjunction with laying order relative to a control group. Certain substances such as carotenoids, immunoglobulins and avidin responded positively to food supplementation, whereas others, such as testoste…

On local optima in minimum time control of the restricted three-body problem

2016

International audience; The structure of local minima for time minimization in the controlled three-body problem is studied. Several homotopies are systematically used to unfold the structure of these local minimizers, and the resulting singularity of the path associated with the value function is analyzed numerically.

Enhancement and assessment of WKS variance parameter for intelligent 3D shape recognition and matching based on MPSO

2016

This paper presents an improved wave kernel signature (WKS) using the modified particle swarm optimization (MPSO)-based intelligent recognition and matching on 3D shapes. We select the first feature vector from WKS, which represents the 3D shape over the first energy scale. The choice of this vector is to reinforce robustness against non-rigid 3D shapes. Furthermore, an optimized WKS-based method for extracting key-points from objects is introduced. Due to its discriminative power, the associated optimized WKS values with each point remain extremely stable, which allows for efficient salient features extraction. To assert our method regarding its robustness against topological deformations,…

Coupled experiment/simulation approach for the design of radiation-hardened rare-earth doped optical fibers and amplifiers

2011

We developed an approach to design radiation-hardened rare earth -doped fibers and amplifiers. This methodology combines testing experiments on these devices with particle swarm optimization (PSO) calculations. The composition of Er/Yb-doped phosphosilicate fibers was improved by introducing Cerium inside their cores. Such composition strongly reduces the amplifier radiation sensitivity, limiting its degradation: we observed a gain decreasing from 19 dB to 18 dB after 50 krad whereas previous studies reported higher degradations up to 0°dB at such doses. PSO calculations, taking only into account the radiation effects on the absorption efficiency around the pump and emission wavelengths, co…
