Análisis y reingeniería de procesos en una empresa prestadora de servicios
2013
La globalización e internacionalización de los mercados, así como el aumento de la competencia arrastran a las organizaciones a plantearse cambiar sus estrategias de negocios. En este sentido, el presente estudio tiene por objeto mejorar el sistema de costes y gestión en una Autoridad Portuaria, mediante la implantación de un sistema de costes y gestión basado en las actividades (ABC/ABM). Con ello, se pretende dar respuesta a la necesidad que tenía esta entidad de adaptar su sistema de información interna a estas nuevas exigencias del mercado obteniendo, por consiguiente, una información de mayor calidad para lograr una gestión estratégica de sus costes.
Calculations of organic-solvent dispersions of single-wall carbon nanotubes
2005
The aqueous solubility Sw and 1-octanol–(Po), cyclohexane–(Pch), and chloroform–(Pcf) water partition coefficients are calculated. The properties of single-wall carbon nanotubes (SWNT) are related to the indices (n, m) designating the chiral vector. SWNTs are classified in zigzag (n, 0), armchair (n, n), and chiral (n, m). These properties permit classifying SWNTs according to (n, m). Correlations between (n2 + nm + m2)1/2, log Sw, log Po, log Pch, and log Pcf show that (n, m) are adequate indices. The (10,10) is the most abundant SWNT, presenting consistency between great kinetic stability, small Sw, and great {Po, Pch, Pcf}. The room temperature solubility of SWNTs is investigated in a va…
L’ADERENZA ALLA TERAPIA FARMACOLOGICA EVIDENCE-BASED DOPO DIMISSIONE OSPEDALIERA A SEGUITO DI INFARTO MIOCARDICO ACUTO (IMA) IN SICILIA
2014
Introduzione L’aderenza alla terapia farmacologica nella fase post-acuta dell’IMA è divenuto oggetto di crescente interesse. È stato evidenziato, che un uso non appropriato di farmaci si associa ad un aumento del rischio di morte e di ulteriori eventi cardiovascolari. Obiettivi Stimare l’aderenza alla terapia farmacologica evidence-based (EBM) nei 12 mesi dopo la dimissione ospedaliera in una coorte di pazienti dimessi dopo ricovero per IMA in Sicilia e di valutare la possibile variabilità tra le 9 ASP della regione, tenendo conto di caratteristiche socio-demografiche e della gravità clinica dei pazienti. Metodi Studio osservazionale di coorte sui pazienti residenti in Sicilia e dimessi da …
Effectiveness of an Emotional Intelligence Intervention and Its Impact on Academic Performance in Spanish Pre-Adolescent Elementary Students: Results…
2020
There is clear agreement about the importance of promoting emotional intelligence in school through programs integrated in the academic curriculum. The objective of this study is to analyze the impact of the EDI program on the emotional intelligence trait and on general academic performance, as well as mathematics and language performance. The participants were 5th grade elementary school students between 10 and 11 years old. A quasi-experimental repeated-measures design was used, with a comparison group and four assessment points. The results showed, on the one hand, the effectiveness of a two-year intervention in improving emotional intelligence and, on the other hand, its positive influe…
Anti-glomerular basement membrane antibody-mediated glomerulonephritis due to glue sniffing
1987
A 16-year-old girl developed rapidly progressive glomerulonephritis and renal failure. The disease was associated with high titres of antiglomerular basement membrane antibodies in serum, linear deposits of immunoglobulin G and diffuse epithelial crescents on renal biopsy. Past history revealed heavy smoking and deliberate sniffing of Pattex glue, a mixture of hydrocarbons which possibly may affect the structure of glomerular basement membrane. After treatment by repeated plasmapheresis and drug immunosuppression autoantibodies disappeared from serum but renal function was not influenced. Renal damage is a potential hazard for glue sniffing adolescents.
Importance of Sampling Frequency to Detect Differential Timing of Migration: A Case Study with BlackcapsSylvia atricapilla
2009
Our aim was to assess to what extent detection of differential timing of passage in migrant birds depends on the sampling frequency (SF). We determined if Blackcaps Sylvia atricapilla performed differential migration by age and sex when passing over N Iberia. We mist netted and ringed migrating Blackcaps at a stopover site, both during the autumn (2005) and the spring (2006) migrations. During autumn, adult female Blackcaps passed later than juvenile birds and adult males. In spring, however, migration differed mainly by sex rather than by age. In particular, males passed over earlier than females, likely due to the pressure on males to earlier arrival at their breeding areas. A simulation …
Advanced Platelet-Rich Fibrin: A New Concept for Cell-Based Tissue Engineering by Means of Inflammatory Cells
2014
Choukroun's platelet-rich fibrin (PRF) is obtained from blood without adding anticoagulants. In this study, protocols for standard platelet-rich fibrin (S-PRF) (2700 rpm, 12 minutes) and advanced platelet-rich fibrin (A-PRF) (1500 rpm, 14 minutes) were compared to establish by histological cell detection and histomorphometrical measurement of cell distribution the effects of the centrifugal force (speed and time) on the distribution of cells relevant for wound healing and tissue regeneration. Immunohistochemistry for monocytes, T and B -lymphocytes, neutrophilic granulocytes, CD34-positive stem cells, and platelets was performed on clots produced from four different human donors. Platelets …
Focal nodular hyperplasia: a weight-based, intraindividual comparison of gadobenate dimeglumine and gadoxetate disodium-enhanced MRI
2019
PURPOSE: We aimed to qualitatively and quantitatively compare the enhancement pattern of focal nodular hyperplasia after gadobenate dimeglumine and gadoxetate disodium injection in the same patient. METHODS: 1.5 T magnetic resonance imaging (MRI) examinations of 16 patients with 21 focal nodular hyperplasias studied after the injection of both contrast media were evaluated. Both MRI studies were performed in all patients. A qualitative analysis was performed evaluating each lesion in all phases. For quantitative analysis we calculated signal intensity ratio, lesion-to-liver contrast ratio and liver parenchyma signal intensity gain on hepatobiliary phase. Statistical analysis was performed w…
Characterization of 14 novel deletions underlying Rubinstein–Taybi syndrome: an update of the CREBBP deletion repertoire
2015
Rubinstein–Taybi syndrome (RSTS) is a rare, clinically heterogeneous disorder characterized by cognitive impairment and several multiple congenital anomalies. The syndrome is caused by almost private point mutations in the CREBBP (~55 % of cases) and EP300 (~8 %) genes. The CREBBP mutational spectrum is variegated and characterized by point mutations (30–50 %) and deletions (~10 %). The latter are diverse in size and genomic position and remove either the whole CREBBP gene and its flanking regions or only an intragenic portion. Here, we report 14 novel CREBBP deletions ranging from single exons to the whole gene and flanking regions which were identified by applying complementary cytomolecu…
