An Integral on a Complete Metric Measure Space
2015
We study a Henstock-Kurzweil type integral defined on a complete metric measure space \(X\) endowed with a Radon measure \(\mu\) and with a family of “cells” \(\mathcal{F}\) that satisfies the Vitali covering theorem with respect to \(\mu\). This integral encloses, in particular, the classical Henstock-Kurzweil integral on the real line, the dyadic Henstock-Kurzweil integral, the Mawhin’s integral [19], and the \(s\)-HK integral [4]. The main result of this paper is the extension of the usual descriptive characterizations of the Henstock-Kurzweil integral on the real line, in terms of \(ACG^*\) functions (Main Theorem 1) and in terms of variational measures (Main Theorem 2).
Artesanado sedero y capital comercial en la Valencia del siglo XVIII
1997
The intense development of the «Verlagssystem» in the XVIII century silk industry in Valencia showed the difficulties of the traditional craftsmen to keep their economic independence. In order to fighy against it, the craftsmen adopted several initiatives, which dealt with the constitution of a share-holding company, as much as with the creation of a communal store to favour the suppley of raw materials to the factories. The most important project was the constitution of the «Compañía de Nuestra Señora de los Desamparados» in 1772. But the requirement of the General Board of Commerce to allow all the social classes to take part in shareholders, as it was not accompanied by the modification …
Crystallite size of kaolinites as indicator of different geochemical types of bauxite
2009
A simple microstructural X-ray diffraction analysis using the Voigt function method reveals differences between bauxite deposits in the Iberian Range Catalanides area (NE, Spain). The highest values of apparent crystallite sizes, measured by volume weighted Dv values from 001 kaolinite reflection, have been found in bauxites of type 1.
Stability of solution for Rao-Nakra sandwich beam model with Kelvin-Voigt damping and time delay
2022
This paper deals with stability of solution for a one-dimensional model of Rao?Nakra sandwich beam with Kelvin?Voigt damping and time delay given by ??1?1?????? ? ??1?1?????? ? ??(??? + ?? + ??????) ? ?????????? ? ??????????( ? , ?? ? ??) = 0, ??3?3?????? ? ??3?3?????? + ??(??? + ?? + ??????) ? ?????????? = 0, ????????? + ?????????????? ? ????(??? + ?? + ??????)?? ? ?????????? = 0. A sandwich beam is an engineering model that consists of three layers: two stiff outer layers, bottom and top faces, and a more compliant inner layer called ?core layer?. Rao?Nakra system consists of three layers and the assumption is that there is no slip at the interface between contacts. The top and bottom lay…

A modified mark test for own-body recognition in pig-tailed macaques (Macaca nemestrina).
2009
Classic mirror self-recognition mark tests involve familiarizing the subject with its mirror image, surreptitiously applying a mark on the subject's eyebrow, nose, or ear, and measuring self-directed behaviors toward the mark. For many non-human primate species, however, direct gaze at the face constitutes an aggressive and threatening signal. It is therefore possible that monkeys fail the mark test because they do not closely inspect their faces in a mirror and hence they have no expectations about their physical appearance. In the current study, we prevented two pig-tailed macaques (Macaca nemestrina) from seeing their own faces in a mirror, and we adopted a modified version of the classi…
A new procedure to determine the rheological properties of RAP binder and corresponding bituminous blends
2017
Abstract In this paper, a new and simple approach to estimate the rheological properties of Reclaimed Asphalt Pavement (RAP) binder is proposed to overcome the limitations of the conventional extraction procedure. This method is based on Dynamic Shear Rheometer tests performed on mortars composed of RAP fine fraction and virgin binder, together with a new back-calculation solution. The properties of the bituminous blends of virgin and RAP binders are obtained with a modified Nielsen model. The Voigt model is then successfully used to estimate complex modulus and phase angle of the RAP binder from the properties of the back-calculated binder blend. This procedure would prevent the need of RA…
Flexural and Shear Resistance of Steel Fiber–Reinforced Lightweight Concrete Beams
2014
In the present paper an analytical model is proposed that is able to determine the shear resistance of lightweight reinforced concrete beams with longitudinal bars, in the presence of reinforcing steel fibers. The model is based on the evaluation of the resistance contribution resulting from beam and arch actions. For the resistance contribution of main bars in tension, the residual bond adherence of steel bars and the crack spacing of reinforced concrete (RC) beams in the presence of fibers are considered. The contribution in terms of postcracking resistance in the tension zone of the beams is also included. The model was verified on the basis of experimental data available in the literatu…
Tonnenkonkremente im Ductus choledochus bei einer 4 Jahre vergessenen, impaktierten Endoprothese
2006
We report on a 67-year-old female patient who presented in July 2005 with sudden onset of pain in the right upper abdomen. The patient had undergone cholecystectomy in 1987. Because of recurrrent complaints in the right upper abdomen, a pigtail stent was placed into the common hepatic duct in 2001. When the patients presented now, the laboratory tests including liver enzymes were within normal ranges. Endoscopic retrograde cholangiogi aphy, however, revealed a remaining 10-French, impacted double pigtail endoprothesis that was obstructed by sludge as well as multiple giant bile duct stones of 20 to 30 mm in size. The giant stones could be finally removed by the combined use of ESWL and endo…
Improved technique for sheath supported contralateral limb gate cannulation in endovascular abdominal aortic aneurysm repair
2019
Summary: Background: To present a technique of sheath supported contralateral limb gate (CLG) cannulation of modular bifurcated stent-graft in endovascular abdominal aortic repair. Materials and methods: After totally percutaneous bilateral femoral access, the 9F introducer sheath is exchanged to a 30 cm 12 fr introducer sheath over a stiff wire contralateral to the intended main stent-graft insertion side and advanced into the aorta below the lowest renal artery. Parallel to the stiff wire within the sheath an additional standard J-tip guidewire with a 5 fr Pigtail angiographic catheter is advanced to the level of the renal arteries. After main body deployment, the 12 fr introducer sheath…
