We show that there exist c-generated algebras (and dense in C^infty([0,1])) every nonzero element of which is a nowhere Gevrey diff erentiable function. This leads to results of dense algebrability (and, therefore, lineability) of functions enjoying this property. In the process of proving these results we also provide a new construction of nowhere Gevrey di fferentiable functions. [less ▲]

Shift-share analysis is a decomposition technique widely used in regional studies to quantify an industry-mix effect and a competitive effect on the growth of regional employment (or any other relevant variable) relative to the national average. This technique has always been subject to criticism for its lack of theoretical basis. This paper presents a critical assessment of the methods suggested by Dunn (1960) and by Esteban-Marquillas (1972) and proposes a new shift-share method, which separates out the two effects unambiguously. By way of illustration, we provide an application to manufacturing employment in the Belgian provinces between 1995 and 2007. [less ▲]

Iñigo de Brizuela and Andrés de Soto, both confessors of the Archdukes were key figures at Brussels' court. Each of them used to influence the policy, using different bias. But they weren't trying to reach similar goals: Brizuela carefully acted to preserve Spanish interests in the Catholic Netherlands, while de Soto struggled for a Catholic victory. Their political actions and its reasons will be covered by this paper. [less ▲]

In the Middle Ages and premodern period, artisanal knowledge was transmitted via collections of recipes often grouped concomitantly with alchemical texts and instructions. Except for some very well-known artistic treatises, such as those by Eraclius or the Schedula diversarum artium, attributed to Theophilus, detection and identification of alchemical content within recipe books has been rare and fraught with difficulty. In a broad sense, alchemy could be defined as the ‘art of transmutation’, referring to the perfection of base or impure matter (often metal or stone) into perfect substances. In this context, alchemical procedures rely on artisanal or craft practices. Thus, any overlap between alchemy and art-technological procedures can be explained by the use of various identical materials and substances. Both are concerned with the description of colours—especially in regard to processes of change, the making of pigments, the production of artificial gemstones, the imitation of gold and silver and the transmutation of materials. Both require procedures involving precise and specifically defined actions, prescriptions and ingredients. So both use identical rhetorical recipe formulations that reflect a ‘step by step’ procedure. Assuming that alchemical and artistic texts have the same textual format, raises the question: did they also have the same methods of production and reception? Using a corpus of about forty manuscripts produced in Northern Europe between the fourteenth and the sixteenth centuries, this paper investigates the authorship and the context of production behind these writings, and scrutinizes the process of their compilation and dissemination. This serves, on a variety of levels, to elucidate information about their former nature and use. Finally, this paper examines the various ways alchemical and artisanal recipes were embedded within recipe books. It also proposes some clues to help in locating, identifying and demarcating this type of alchemical writing within the literature of recipes. [less ▲]

This document compares the contents of the Free Trade Agreements (FTA) that have been signed by the European Union and by the United States with Colombia. It analyses them from a perspective that characterizes FTAs into “WTO-extra” and “WTO-plus” agreements. By this analysis, an “Americanization” of the European interregional strategy is partially verified. Nevertheless, this “Americanization” appears to be partial, due to the inclusion of “regional integration” as a transversal theme in European FTA. [less ▲]

Serum creatinine (SCr) is the main variable for estimating glomerular filtration rate (GFR). Due to interassay differences, the prevalence of chronic kidney disease (CKD) varies according to the assay used, and calibration standardization is necessary. For SCr, isotope dilution mass spectrometry (IDMS) is the gold standard. Systematic differences are observed between Jaffe and enzymatic methods. Manufacturers subtract 0.30 mg/dl from Jaffe results to match enzymatic results (‘compensated Jaffe method’). The analytical performance of enzymatic methods is superior to that of Jaffe methods. In the original Modification of Diet in Renal Disease (MDRD) equation, SCr was measured by a Jaffe Beckman assay, which was later recalibrated. A limitation of this equation was an underestimation of GFR in the high range. The Chronic Kidney Disease Epidemiology (CKD-EPI) consortium proposed an equation using calibrated and IDMS traceable SCr. The gain in performance was due to improving the bias whereas the precision was comparable. The CKD-EPI equation performs better at high GFR levels (GFR[60 ml/ min/1.73 m2). Analytical limitations have led to the recommendation to give a grade ([60 ml/min/1.73 m2) rather than an absolute value with the MDRD equation. By using both enzymatic and calibrated methods, this cutoff-grade could be increased to 90 ml/min/1.73 m2 (with MDRD) and 120 ml/min/1.73 m2 (with CKD-EPI). The superiority of the CKD-EPI equation over MDRD is analytical, but the precision gain is limited. IDMS traceable enzymatic methods have been used in the development of the Lund– Malmo¨ (in CKD populations) and Berlin Initiative Study equations (in the elderly). The analytical errors for cystatin C are grossly comparable to issues found with SCr. Standardization is available since 2011. A reference method for cystatin C is still lacking. Equations based on standardized cystatin C or cystatin C and creatinine have been proposed. The better performance of these equations (especially the combined CKD-EPI equation) has been demonstrated.

Jatropha curcas, ou Pourghère, est un arbuste de la famille des Euphorbiacées, largement répandu dans les pays tropicaux. Ses graines sont riches d'une huile pouvant servir de biocarburant dans les moteurs diesels modifiés. La plante est attaquée par divers insectes ravageurs appartenant principalement aux ordres des Hétéroptères, Coléoptères et Orthoptères. Ils provoquent des dégâts sur les fruits, les inflorescences et les feuilles. Les ravageurs les plus fréquemment observés sur J. curcas sont des punaises du genre Pachycoris (Hétéroptère : Scutelleridae), qui sont largement répandues au Mexique, en Australie, aux États-Unis, au Brésil et au Nicaragua. Ces punaises causent des dégâts importants sur les fruits et provoquent la malformation des graines, et avec elle une réduction de la teneur en huile. Même si les arbustes de Jatropha sont victime d'infestations d'insectes, plusieurs études démontrent l'effet insecticide de son huile contre des ravageurs importants tels que Busseola fusca (Fuller) (Lépidoptère : Noctuidae), Sesamia calamistis Hampson (Lépidoptère : Noctuidae), Aphis gossypii Glover (Homoptère: Aphididae) et Callosobruchus chinensis L. (Coléoptère : Bruchidae). Dans ce document, nous présentons dans une première partie les principaux insectes ravageurs de J. curcas et dans une seconde section les effets insecticides démontrés de son huile. [less ▲]

This paper presents the results of an experimental campaign performed to assess the effect of the flame emissivity for steel members engulfed into fire. In detail, two sizes of circular steel tubes were engulfed into pool fires of two different diameters. Two fuels were used and for both fuels tests without column (used as comparison with existing localised fire models) and with column were performed. The temperature of the column and of the flames were measured at different heights. The width of the flame was also measured and used to calculate the emissivity of the flame the value of which was employed in numerical simulations in order to predict the evolution of the temperature of the steel column. Comparison with numerical analyses where the recommended values of the Eurocode were used is also shown. [less ▲]
