Nanofiltration is nowadays established in many industries for the separation and purification of aqueous solutions. The maximum operating temperature of commercial nanofiltration membrane is often given with 50 – 60 ºC based on the three-layer structure of membranes consisting of a polyester or polypropylene support paper with a polysulphone support layer and an active layer of polyamide. Operatin
In chapter 5, Juan Carlos Mendoza Collazos presents an overview of a new approach to signification, known as agentive semiotics, that “links achievements of logic, phenomenology and cognitive sciences” (Niño 2015). As the author states, this clearly aligns this approach with cognitive semiotics. Similarly, agentive semiotics is influenced by enactivism, though it takes a more specific stand on the
Objetos como los artefactos no interactúan con los usuarios, no significan por sí mismos y no comunican. Estas premisas tienen implicaciones en la forma en que se asumen las actuales tendencias del diseño que dan por sentado, sin mayor atención, las interacciones entre el artefacto y los usuarios, olvidando que dichas interacciones fueron formuladas en un contexto cibernético y no en un contexto s
This book proposes Agentive Semiotics as a new perspective to addressing semiotics of design. The novelty of this perspective lies on that semiotics of design with Agentive approach implies focus not only on the artefacts, but on interactions between agents, mediated by artefacts. Agentive Semiotics takes into account experience as a whole. The book presents applications from theoretical corpus of
The use of cross-flow ultrafiltration for the recovery of coating ma-terial from aqueous streams started about 30 years with electro deposition paint in the automotive industry. This early success can be related to both environmental and economical advantages of using ultrafiltration. Ultrafiltration recovers and concentrate electro deposition paint on the retentate side and produces purified wate
1. IntroductionIn the last two decades the pulp and paper industry has put significant efforts into improving its productivity and reducing its fresh water consumption. Among the different approaches, recycling close to the source has been identified as one of the most effective ways to reduce water consumption and recycle valuable components. The focus of this paper is thus on the different oppor
To catch successfully the new opportunities that arise from the development of new paper-product markets, pulp and paper producers are facing the need to improve the profitability and the environmental profile of their processes. Pulp and paper producers are therefore seeking all means to “close the loops”: the water loop, the chemical loop and the by-product loop. This lecture reviews the opportu
Purpose: The aim of this study was to investigate people’s experiences of living with dysphagia after stroke, and their experiences of dysphagia management. Methods: The study design was qualitative, and an open-ended approach to data collection was used, with follow-up probing questions to gain more information as needed. Personal interviews were conducted with five persons who had persisting mod
Electric Road Systems (ERS) have emerged as an alternative to deal with the main drawbacks that battery electric vehicles present (i.e., higher cost, short driving range, long charging times, etc.). This paper analyses the societal cost of electrifying all road transport in Denmark under four different scenarios. The first scenario considered in this study is based on today's approach of having el
The European pulp and paper industry (PPI) directly emits 31.9 Mton CO2 (2016) and indirectly 12.3 and 5 Mton CO2 from purchased electricity and transport respectively. It also accounts for 68 Mton of biogenic CO2 emissions. The PPI is a mature industry with overall stagnating market demand in the past ten years and relatively high levels of recycling. Forest countries like Sweden and Finland domi
Objectives We compared the effectiveness of an intensive smoking cessation intervention among smokers with and without a severe mental disorder (SMD) and identified factors associated with successful quitting. The main hypothesis was that smokers with an SMD would be less likely to stay continuously smoke-free for 6 months. Design A prospective cohort study. Setting In all, 302 smoking cessation c
The dynamics of isolated-photon production in association with a jet in proton–proton collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 fb−1. Photons are required to have transverse energies above 125 GeV. Jets are identified using the anti-kt algorithm with radius parameter R=0.4 and required to have
Moral panics are events that occur when societies react to a condition, episode, person or group of persons inside their society, which are seen as threats to the society’s core values or beliefs. The concept of moral panic has been successfully employed in the fields of sociology and criminology for well over 40 years. However, it has remained fairly unknown to social psychologists. In this paper
Current distance measurement techniques for pulse wave velocity (PWV) calculation are susceptible to intercenter variability. The aim of this study was to derive and validate a formula for this distance measurement. Based on carotid femoral distance in 1183 whole-body magnetic resonance angiograms, a formula was derived for calculating distance. This was compared with distance measurements in 128
Objectives: Our objectives were to determine first whether albumin prevents heparin-binding protein-induced increased endothelial cell permeability and renal cell inflammation and second, whether a plasma heparin-binding protein-to-albumin ratio predicts risk of acute kidney injury, fluid balance, and plasma cytokine levels in septic shock. Design: In vitro human endothelial and renal cell model a
En este trabajo planteamos cuales son las formas particulares que toma en ciencia la crisis de la civilización. Formas que no siempre son fáciles de advertir. Crisis de la ciencia que es causa y consecuencia de la crisis civilizatoria. Partimos de observaciones realizadas dentro del campo científico que indican un fuerte retroceso de la razón crítica en ciencia quedando vigente solamente la razón
This chapter deals with strategic environmental assessment (SEA) follow-up, which we define as: Monitoring and evaluation of the implementation of a strategic initiative and relevant environmental factors for management of, and communication about, the environmental performance of that strategic initiative.
