推理测验与推理实验不同。推理测验用来衡量智商;而推理实验则用来研究推理的心理过程。测验旨在找出能力的个体差异;而实验则意在突出所有个体的一般性心理过程。近年来,心理学中的推理已经发生了变化,我们在理论进化方面简要地总结了如下这些变化:关注点从推理任务中的反应过程变为个体对不同任务做反应时的差异和其中稳定的反应模式,开始考虑不同推理者的组织差异和数量差异(犹如不同游泳运动员的游泳动作和肌肉数量)。然而,这些理论创新必须有精确的建模技术的支持。我们将以条件推理材料为例,展示了现代心理测量方法可以帮我们解决理论创新中产生的三类主要的研究问题。

The synthesis and characterization of several dispersed molybdena catalysts on silica support (MoO3-SiO2) prepared from a variety of precursors (Mo(VI)-acetylacetonate, oxo-peroxo Mo-species, hydrated ammonium heptamolybdate) and preparation methods (deposition of the Mo-phase on finite SiO2 support by aqueous and methanol impregnations, by adsorption, by oxo-peroxo route-like, and by one-step synthesis of MoO3-SiO2 system with molecular precursors) are presented. The molybdena concentration on silica was comprised in a large interval (1.5 - 14 wt%) depending on the preparation method which governed the Mo-loading on silica. Convenient comparisons among samples at similar Mo-concentration have been made discussing the morphologic-structural (XRD, XPS, UV-vis-DRS, and N2-adsorption) and physicochemical (TG-DTG, TPR, and n-butylamine-TPD) sample properties. Polymeric octahedral polymolybdate aggregates predominated in the samples prepared by aqueous and methanol impregnations, which were at high Mo-concentration. On the contrary, isolated Mo(VI) species in distorted Td symmetry predominated in the sample prepared by adsorption which was at very low Mo-concentration. The sample acidity was composed of a weak acidy site population, associated with the silica support, and a strong acid site population associated with the Mo-dispersed phase. Oxidation tests of formaldehyde, an oxygen-containing VOC (Volatile Organic Compound), were performed to determine the prevalent redox or acidic function of the Mo-species at the surface of the catalysts.

Laser marking is a laser processing technology used in many fields of industry like automotive [1], aerospace [2], microelectronic [3] and medecine [4]. CO2 laser is an appropriate source for marking glasses [5]. Compared to the other techniques of marking, the principal advantages of the use of the laser are: made inalterable, high degree of accuracy and the smoothness of the features, the possibility of marking at difficult to reach places, and the fact of being able to mark fragile materials like ceramic and glass [6]. In this experimental work, the influence of marking parameters like interaction time laser-glass, laser power, shooting time etc. on the micromarking precision are reported. A “melt” depth prediction model has been established.

With the increase of gas consumption and the expansion of the associated distribution network, Gaz de France set up a research program to develop a methodology and a library of models to study the stability of any type of pressure regulator. The pressure level is controlled by pressure regulating stations. The objective of this study is to point out the working conditions that lead to instabilities. Some experiments and numerical simulations have been carried out to identify the relative influence of several parameters on the amplitude of oscillations. It turned out from measurements and simulations that the amplitudes of the downstream pressure are especially sensitive to the upstream pressure and to the size of the downstream volume.

Background: Adipose tissue-derived stem cells (ASC) possess the ability to differentiate into adipocytes or endothelial cells to help in the adipogenesis, vasculogenesis and vascular repair. This study aims at determining the impact of high-fat diets (HFD)-induced type 2 diabetes (T2D) on the differentiation potential of ASC. Results: C57BL/6J male mice were fed a vegetal (VD) or an animal (AD) HFD. Isolation of ACS from mice showing different levels of metabolic alterations reveals that advanced T2D did not affect the number of cells per gram of tissue. Rather, a higher proportion of inflammatory CD36+ cells was identified in HFD fed mice. Despite a marked decreased expression of adipogenic genes (aP2, C/EBPα and PPARγ2), ASC from HFD groups had a higher adipogenic potential and a lower endothelial differentiation potential in vitro compared to control. ASC from the VD group had enhanced cyclin B1 expression and had more adipogenic potential compared to AD group. Conclusion: Our results demonstrate that the metabolic modifications, linked to the nature of fatty acids in diets, modulate the differentiation potential of ASC with increased adipogenesis to the detriment of the endothelial pathway. Results highlight the importance of evaluating the ASC differentiation behavior in a context of autologous cell-based therapy for the repair of vascular tissues in diabetic patients.

Introduction: A fatty acid (FA) is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Recently, the role of FA and particularly omega-3 and -6 has emerged as cardiovascular risk factor in the literature. The aim of our study was to establish reference values for these FA and to compare them with data obtained in a population of acute myocardial infarction (AMI) patients. Materials and methods: Hundred thirty five healthy subjects (59.38 ± 27.12 yo, 75 men) were selected as reference population. We also evaluated FA in thirty three patients (55 ± 9 yo, 23 men) admitted in the Emergency Department of our Institution for AMI. The fasting whole blood was drawn in vacutainer containing EDTA. Before analysis, samples were washed and transmethylated. We performed the quantification of different FA by gas chromatography associated with flame ionization detector (GCFID). Results: We obtained results in control healthy patients to be used as reference values. In the AMI group, levels of omega-6 were significantly higher (p 0.05) for C18:2n6 and C18:3n6 than the reference population and omega-3 values were significantly lower (p 0.01) compared to reference value for C22:6n3. The omega-3 index was lower and the ratio omega-6/omega-3 was higher in AMI group compared to reference values. Conclusions: We have established reference value for FA and have compared these values with the results obtained in AMI population. FA determination is a new tool we are able to use and to process in our laboratory which can help the clinician to screen patients with the highest cardiovascular risks because of the implication of FA in the etiopathogeny of atherosclerosis.
