Is There a Role for Tertiary (TCR) and Quaternary (QCR) Cytoreduction in Recurrent Ovarian Cancer?
2015
BACKGROUND: The aim of the present study was to evaluate the efficacy of tertiary and quaternary cytoreduction in recurrent ovarian cancer patients. PATIENTS AND METHODS:Between January 1997 and December 2014, 53 patients were submitted to cytoreductive surgery for second and third ovarian cancer recurrence at our Unit. RESULTS:Median age at first diagnosis was 48 years (range=20-69). Forty-six patients (86.8%) underwent tertiary cytoreduction. At the time of surgery, isolated and diffuse disease was observed in 48 (90.6%) and 5 (9.4%) patients, respectively. Complete and optimal cytoreduction was obtained in 41 (77.5%) and in 1 (1.9%) patients, respectively. We did not observe any statisti…
Fitting random cash management models to data
2019
Abstract Organizations use cash management models to control balances to both avoid overdrafts and obtain a profit from short-term investments. Most management models are based on control bounds which are derived from the assumption of a particular cash flow probability distribution. In this paper, we relax this strong assumption to fit cash management models to data by means of stochastic and linear programming. We also introduce ensembles of random cash management models which are built by randomly selecting a subsequence of the original cash flow data set. We illustrate our approach by means of a real case study showing that a small random sample of data is enough to fit sufficiently goo…
Short term association between ozone and mortality: global two stage time series study in 406 locations in 20 countries
2020
Objective To assess short term mortality risks and excess mortality associated with exposure to ozone in several cities worldwide. Design Two stage time series analysis. Setting 406 cities in 20 countries, with overlapping periods between 1985 and 2015, collected from the database of Multi-City Multi-Country Collaborative Research Network. Population Deaths for all causes or for external causes only registered in each city within the study period. Main outcome measures Daily total mortality (all or non-external causes only). Results A total of 45 165 171 deaths were analysed in the 406 cities. On average, a 10 µg/m3 increase in ozone during the current and previous day was associated with a…
Effect of Composition on the Photoelectrochemical Behavior of Anodic Oxides on Binary Aluminum Alloys
2006
The photoelectrochemical behavior of anodic films on Al alloys, containing titanium, tantalum, and tungsten (valve metals), has been studied as a function of alloy composition and anodizing conditions. Photocurrent spectroscopy has been used to get information on bandgap and the flatband potential values of different mixed oxides. Both insulator-like and semiconducting behavior has been observed for anodic oxides grown on Al-W and Al-Ti alloys dependent on alloy initial composition. Optical bandgap values, E opt g , of different oxides are in accordance with predictions based on the correlation between E opt g and the difference of electronegativities of the oxide constituents, indicating p…
An application of Matlab c on Dimensional Nonlinear Programming
2014
[EN] Nonlinear Programming (NLP) is a widely applicable tool in modeling real life problems applied to business, economics and engineering. Is to maximize or minimize a scalar field whose domain is given as a set of constraints given by equalities and/or inequalities not necessarily linear. In this paper we present a virtual laboratory to study the PNL graphically and numerically in the case of two variables
Fick Diffusion Coefficients in Ternary Liquid Systems from Equilibrium Molecular Dynamics Simulations
2012
An approach for computing Fick diffusivities directly from equilibrium molecular dynamics (MD) simulations is presented and demonstrated for a ternary chloroform–acetone–methanol liquid mixture. In our approach, Fick diffusivities are calculated from the Maxwell–Stefan (MS) diffusivities and the so-called matrix of thermodynamic factors. MS diffusivities describe the friction between different molecular species and can be directly computed from MD simulations. The thermodynamic factor describes the deviation from ideal mixing behavior and is difficult to extract from both experiments and simulations. Here, we show that the thermodynamic factor in ternary systems can be obtained from density…

Izrael a Palestyńczycy. Wojna i okupacja jako rozwiązanie?
2015
Celem artykułu jest szkic analizy konfliktu izraelsko-palestyńskiego, zwłaszcza w kontekście sposobu radzenia sobie przez państwo żydowskie z palestyńskim ruchem narodowowyzwoleńczym. W pierwszej części zwrócono uwagę na specyficzne okoliczności powstania Izraela – państwo to miejscowa ludność arabska uznała za ostatni europejski projekt kolonialny. Następnie opisano tak zwaną matrycę kontroli nad Palestyńczykami, którą zaprezentował antropolog i aktywista pokojowy Jeff Halper. W ostatniej części skupiono się na Operacji Ochronny Brzeg i jej ofiarach, głównie palestyńskich cywilach. Artykuł kończy się wskazaniem dwóch generalnych kierunków, w których może ewoluować opisywany konflikt.
Determinants of elimination decisions in the activity scheduling process
2016
[EN] This paper presents an analysis on the determinants related to a particular rescheduling decision in the activity-travel scheduling process: elimination decisions, which consist in the non-execution of pre-planned activity-travel episodes. Data used come from an in-depth computer-assisted telephone interview (CATI) follow up survey carried out during the implementation of the first wave of an activity scheduling process panel survey. Open-ended answers related to the reasons associated to changes between pre-planned and executed agenda are studied. First, an interpretative qualitative method based on analytic induction (AI) is used to cope with the complex nature of the rescheduling de…
