What makes environmental performance differ between firms? Empirical evidence from the Spanish tile industry

2007

Environmental performance is a matter of major concern both for policy makers and for firm managers. In this paper we interpret firms' environmental performance as their ability to reduce polluting wastes while maintaining observed levels of inputs and desirable outputs. Making use of data envelopment analysis techniques, we compute waste-specific environmental efficiency measures for a sample of ceramic-tile producers located in the eastern Spanish region of Valencia. Our results show that there exists substantial room for improving environmental performance, which would have highly beneficial consequences for the local environment. In a second stage of analysis, we find that affiliation …

La revolución del pudor: escándalos, género y política en la crisis de la Monarquía liberal en España

2018

En este artículo se trata de analizar el carácter performativo de los grandes escándalos morales y políticos en torno a la familia real, que afectaron a la imagen pública y a los mecanismos de legitimación de la monarquía liberal en España durante el reinado isabelino. Abordo el tema desde la perspectiva actual de reflexión sobre la imbricación histórica de las nociones de virtud política y escándalo moral que dio lugar a la idea de «corrupción» en el universo liberal. Una idea que, como trato de demostrar, tuvo fuertes connotaciones de género, estuvo ligada a la dinámica de construcción del Estado nación, obliga a una ampliación sustancial de nuestra noción de «lo político», sugiere el car…

Comparison of quantitative Holocene temperature reconstructions using multiple proxies from a northern boreal lake

2017

Four biotic proxies (plant macrofossils, pollen, chironomids and diatoms) are employed to quantitatively reconstruct variations in mean July air temperatures ( Tjul) at Lake Loitsana (northern Finland) during the Holocene. The aim is to evaluate the robustness and biases in these temperature reconstructions and to compare the timing of highest Tjul in the individual reconstructions. The reconstructed Tjul values are evaluated in relation to local-scale/site-specific processes associated with the Holocene lake development at Loitsana as these factors have been shown to significantly influence the fossil assemblages found in the Lake Loitsana sediments. While pollen-based temperatures follow…

Lower ST-elevation myocardial infarction incidence during COVID-19 epidemic in Northern Europe

2020

We compared the ST elevation myocardial infarction (STEMI) incidence during COVID-19 pandemic (March 2020) to January-February 2020 and to same time period in earlier years 2017-2019 in five Nordic-Baltic tertiary centers. During 2017-2019, there were no marked differences in STEMI incidence between January, February and March. During 2020, there was an average drop of 32% in STEMI incidence in March. The isolation measures may decrease the risk for respiratory virus infection and contribute to the lower STEMI incidence and that we might benefit from firmer suggestions on hand hygiene and social distancing during flu season at least among high-risk individuals.

2D size, position and shape definition of defects by B-scan image analysis

2015

The non-destructive evaluation of defects by automatic procedures is of great importance for structural components. Thanks to the developments of the non-contact ultrasonic techniques, the automation of the inspections is gaining a progressively important role. In this work, an automatic inspection technique for the evaluation of defects by the analysis of B-scan images obtained by a laser ultrasonic system is presented. The data are extracted directly from a B-scan map obtained for a panel with internal defects, and are used to build an image of the cross section of the panel. The proposed automatic procedure allows the definition of size, position and shape of defects in panels of known t…

A coarse to fine 3D acquisition system

2015

International audience; The 3D chain (acquisition-processing-compression) is , most of the time , sequenced into several steps. Such approaches result into an one-dense acquisition of 3D points. In large scope of applications , the first processing step consists in simplifying the data. In this paper , we propose a coarse to fine acquisition system which permits to obtain simplified data directly from the acquisition. By calculating some complementary information from 2D images , such as 3D normals , multiple homogeneous regions will be segmented and affected to a given primitive class. Contrary to other studies , the whole process is not based on a mesh. The obtained model is simplified di…

Solid microcrystalline dispersion films as a new strategy to improve the dissolution rate of poorly water soluble drugs: A case study using olanzapine

2016

In this study, we evaluate the dissolution rate enhancement of solid microcrystalline dispersion (SMD) films of olanzapine (OLZ) formulated with four water-soluble polymers namely poly(N-vinylpyrrolidone) (PVP), poloxamer 188 (P188), poloxamer 407 (P407) and Soluplus(®) (SLP). Prepared formulations were characterised to determine particle size, morphology, hydrogen bonding interactions, thermal characteristics as well as in vitro dissolution studies conducted under sink conditions (pH 6.8). Particle size of OLZ in all formulations ranged between 42 and 58μm. Attenuated Total Reflectance Fourier Transform Infrared spectroscopy (ATR-FTIR), Differential Scanning Calorimetry (DSC) and Hot-Stage…

COMBINATION OF ARGAN OIL AND PHOSPHOLIPIDS FOR THE DEVELOPMENT OF AN EFFECTIVE LIPOSOME-LIKE FORMULATION ABLE TO IMPROVE SKIN HYDRATION AND ALLANTOIN…

2016

Allantoin is traditionally employed in the treatment of skin ulcers and hypertrophic scars. In the present work, to improve its local deposition in the skin and deeper tissues, allantoin was incorporated in conventional liposomes and in new argan oil enriched liposomes. In both cases, obtained vesicles were unilamellar, as confirmed by cryo-TEM observation, but the addition of argan oil allowed a slight increase of the mean diameter (∼130nm versus ∼85nm). The formulations, especially those containing argan oil, favoured the allantoin accumulation in the skin, in particular in the dermis (∼8.7μg/cm(2)), and its permeation through the skin (∼33μg/cm(2)). The performances of vesicles as skin d…

La digitalizzazione del patrimonio come strumento per la conoscenza, un’esperienza sull’architettura ferroviaria siciliana

2022

The process of digitisation of the artistic and cultural heritage has enriched the possibilities of representation and communication of architecture, increasing the modes of reproduction, fruition as well as the possibilities of protection and preservation. The study of this research draws attention on the continuous progress of technology in the cultural field and highlights the important collaboration that exists between digital and analog representation, identifying, with this synergy, a virtuous path that allows, through the use of different methodologies, to be able to know and analyze the historical phases of a building. In particular, the attention was directed to the Caltanissetta C…
