Can we improve the birth weight prediction?: the effect of normal BMI using a multivariate model
2015
Objective: The construction of a predictive model that improves the estimation of the fetal weight (EFW). Study Design: a comparative, descriptive study. One hundred forty pregnant women were recruited at two-stage sample in health department in Spain. They were classified in four groups depending on the pre-gestational BMI. Fetal weight at term was estimated by ultrasound at 33-35 weeks (EFW40w) by one gynecologist. A regression model was created with the variables that reacted to the newborn's weight, symphysis-fundal height (SFH), EFW40w, gestational age (GA), ferritin level and cigarettes smoked. Results: A multivariate model was created for the NW group to estimate the fetal weight (EF…
Evaluating evaluative bibliometrics: a case study of two research groups
2018
Bibliometrics is a method increasingly used to perform evaluations of scientific output and impact, in particular in order to distribute means, such as research grants. But also internally within universities and other research institutions. Various performance and impact meaures are used to establish quality of research. This can be highly problematic, not only in terms of ethics, but also with regards to method. Especially considering the proliferation of tools to perform bibliometric analysis, which means that analyses are increasingly performed without actual understanding of bibliometrics as a scientific method. In our research we have compared two research groups in the same field of …
The editorial function of the territorial intelligence systems
2006
This communication makes an updating of our thinking about the editorial function of the systems of territorial intelligence. Computer science and information systems aim at increasing the communication between the human beings. A territorial intelligence system is an instrument at the service of the actors who ambition to control the development the equitable and sustainable development of their territory. Since the irruption of data processing, we led research activities to design friendly software, then to model the structure of a territorial information system that is at the service of a network of territorial actors, and more recently to integrate the data analysis functions. They led …
‘I don’t know the answer to that question’: a corpus-assisted discourse analysis of White House Press Briefings
2013
White House Press Briefings, daily meetings with the press held by the White House Press Secretary, are the main information conduit for the White House (Kumar 2007). They are considered a “political chess game” where the Press Secretary and the press face a “wrestling match” (Partington 2006: 16). Our analysis is carried out on a corpus comprising all the Press Briefings across three presidencies from Clinton to Obama. The additional mark-up includes information about individual speakers and their role, allowing us to compare different discourse strategies adopted by the participants in the briefings at different points in time. This leads us to determine the extent of the differences in t…

Initial strain effects in multilayer composite laminates
2001
A boundary integral formulation for the analysis of stress fields induced in composite laminates by initial strains, such as may be due to temperature changes and moisture absorption is presented. The study is formulated on the basis of the theory of generalized orthotropic thermo-elasticity and the governing integral equations are directly deduced through the generalized reciprocity theorem. A suitable expression of the problem fundamental solutions is given for use in computations. The resulting linear system of algebraic equations is obtained by the boundary element method and stress interlaminar distributions in the boundary-layer are calculated by using a boundary only discretization. …
Characterization of Chlorolignins in Bleached Kraft Pulp Mill Effluents Using Elemental Analysis and Fingerprinting by CuO Oxidation And Hplc
1994
Abstract Elemental analyses and chemical degradation techniques were applied to characterize lignin compounds in different stages of the chlorine bleaching process and in total mill effluent. Ultrafiltration was used for separation of chlorolignins into three nominal molecular weight fractions. Alkaline CuO oxidation products were analyzed by HPLC with diode array detection. Major compounds were identified by reference to authentic compounds. For comparison, native lignins (MWL), kraft lignins, and humic substances were studied as well. The oxygen, carbon and organic chlorine contents were closely similar in the various mill samples and their fractions. In all mill samples, vanillin and 6-c…
High-statistics study of f0(1500) decay into π0π0
1995
Abstract A partial-wave analysis of the reaction p p →π 0 π 0 π 0 has been performed using a high-quality high-statistics data set of 712 000 events. In addition to the f0(975) and f0(1300), the scalar resonance with mass m = (1500 ± 15) MeV and width Γ = (120 ± 25) MeV is necessary to describe the data.
