Visualization of Large Terrain Using Non-restricted Quadtree Triangulations
2004
This paper presents a set of new techniques oriented towards the real-time visualization of large terrains. These techniques are mainly focused on semi-regular triangulations of non-restricted quadtree terrain representations. Despite the fact that the paper shows that triangulations based on non-restricted quadtrees are as simple and efficient as those based on restricted quadtrees, the new triangulations avoid discontinuity problems among the boundaries of different patches without the need for tree balancing and extra triangles addition. Another important feature of the proposed triangulation is that it incorporates an efficient method for building triangle strips and triangle fans for t…
Polymorphisms in DNA repair genes modulate survival in cisplatin/gemcitabine-treated non-small-cell lung cancer patients.
2006
Abstract Background: Impaired DNA repair capacity may favorably affect survival in cisplatin/gemcitabine-treated non-small-cell lung cancer (NSCLC) patients. We investigated the association of survival with genetic polymorphisms in X-ray repair cross-complementing group 1 and group 3 (XRCC3), xeroderma pigmentosum group D (XPD), excision repair cross-complementing group 1, ligase IV, ribonucleotide reductase, TP53, cyclooxygenase-2, interleukin-6, peroxisome proliferator-activated receptor γ, epidermal growth factor, methylene-tetra-hydrofolate reductase and methionine synthase. Patients and methods: One hundred and thirty-five stage IV or IIIB (with malignant pleural effusion) NSCLC patien…
Data structures and algorithms for topological analysis
2014
International audience; One of the steps of geometric modeling is to know the topology and/or the geometry of the objects considered. This paper presents different data structures and algorithms used in this study. We are particularly interested by algebraic structures, eg homotopy and homology groups, the Betti numbers, the Euler characteristic, or the Morse-Smale complex. We have to be able to compute these data structures, and for (homotopy and homology) groups, we also want to compute their generators. We are also interested in algorithms CIA and HIA presented in the thesis of Nicolas DELANOUE, which respectively compute the connected components and the homotopy type of a set defined by…
Isolated lung perfusion with chemotherapy in a pig model
2014
Introduction: The isolated lung perfusion (ILP) is an experimental technique which main objective is to deliver high dose of cytotoxic agent to the lung tissue without systemic exposure. The thesis took place in three stages: first stage, setting in vitro the chemotherapy the most efficient against colorectal cancer (CCR) cells in 30 min. Second stage, develop the ILP technique in a pig model. Third stage, lead a dose escalation study with chemotherapy by ILP.Methods: First stage, efficacy of various cytotoxic molecules against a panel of human CCR cell lines was tested in vitro after a 30-minute exposure. Second stage, pigs were treated with chemotherapy delivered by ILP during 30 minutes …
The controller's role in environmental management control
2014
This paper explores the role of the management controller in environmental management control (EMC) by means of a longitudinal case study of a French company with a pioneering approach to EMC. The results show that the management controller has four key roles (carbon auditor, business partner, euro-carbon translator, and agent of change) and illustrate the characteristics of the controller in this new domain (image, power of influence, and territory). Several theoretical, managerial, and methodological lessons may be learned from this case study.
Passive sampling in monitoring of nonylphenol ethoxylates and nonylphenol in aquatic environments
2012
The present practices for determining the concentration levels of various pollutants are in many respects insufficient and for this reason, there is an urgent need especially to develop more cost-effective sampling methods. In this study, a novel passive sampling tool (the Chemcatcher®) for monitoring nonylphenol ethoxylates (NPEOs) and nonylphenol (NP) in aqueous media was tested. These environmentally harmful substances have been widely used in different household and industrial applications and they affect aquatic ecosystems, for example, by acting as endocrine disrupting compounds. The highest accumulation of NPEOs and NP in laboratory-scale tests was obtained when using an SDB-XC (stan…
Superallowed α Decay to Doubly Magic 100Sn
2018
We report the first observation of the 108Xe→104Te→100Sn α-decay chain. The α emitters, 108Xe [Eα=4.4(2) MeV, T1/2=58+106−23 μs] and 104Te [Eα=4.9(2) MeV, T1/2<18 ns], decaying into doubly magic 100Sn were produced using a fusion-evaporation reaction 54Fe(58Ni,4n)108Xe, and identified with a recoil mass separator and an implantation-decay correlation technique. This is the first time α radioactivity has been observed to a heavy self-conjugate nucleus. A previous benchmark for study of this fundamental decay mode has been the decay of 212Po into doubly magic 208Pb. Enhanced proton-neutron interactions in the N=Z parent nuclei may result in superallowed α decays with reduced α-decay wi…
Grzech, wina i przebaczenie Refleksje na podstawie stanowiska Kościoła Ewangelickiego w Niemczech (EKD)
2022
Czym jest grzech, wina i przebaczenie? Te kwestie zostały poruszone w opublikowanym w 2020 r. dokumencie Kościoła Ewangelickiego w Niemczech z perspektywy protestanckiej antropologii. Celem niniejszego artykułu jest podjęcie refleksji wokół najważniejszych idei tego dokumentu EKD, jakie wyznaczają jego poszczególne części: (1) grzech oraz fenomen grzeszenia; (2) zagubiony człowiek i odpowiedź Biblii; (3) miejsca doświadczenia winy, przebaczenia oraz pojednania. Refleksje te dotykają niewątpliwie podstawowego przesłania Reformacji, jakim jest usprawiedliwienie grzesznika. Wiele z tych przemyśleń może być bardzo pouczające w kontekście toczących się obecnie dyskusji na temat przebaczenia i po…
High resistance against clindamycin, metronidazole and amoxicillin in Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans isolates of …
2010
Objectives: To test the antimicrobial sensitivity of two periodontal pathogens to a panel of five orally administrable antibiotics in periodontal disease. Study design: A total of 69 isolates of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis were processed using culture and biochemical tests. Selected colonies of A. actinomycetemcomitans and P. gingivalis were used to evaluate the antibacterial activity of clindamycin, metronidazole, amoxicillin, moxifloxacin and amoxicillin/clavulanic acid. Results: Susceptibility testing revealed a sensitivity of 100% of A. actinomycetemcomitans and P. gingivalis to moxifloxacin and amoxicillin/clavulanic acid but moderate susceptibili…
Intravesical gemcitabine in superficial bladder tumours preliminary results of a phase I-II study
2003
INTRODUCTION & OBJECTIVES: Gemcttabme is a pro-drug requmng intracellular phosphorylation by deoxycytidine kinase to be activated. Preliminary experiences. suggesting the activtty and the good tolerability of the drug on superficial transitional cell carcinoma of the bladder (TCCB) when administered by intravesical route, have been recently published. The mm of the present study was to evaluate the ablative efftcacy of weekly intravesical instillations of gemcitabine against paptllary marker lesions left after TUR of superficial TCCB. The scientific background and the ethical acceptability of thts approach have been balidated by the European Organization for Research and Treatment ot Cancer…
