Initiation and duration of dual antiplatelet therapy after inpatient percutaneous coronary intervention with stent implantation in Germany: An electr…

2017

Abstract Background Studies assessing the routine outpatient dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in Germany are scarce. The aim of this study was (i) to investigate the initiation and duration of DAPT after inpatient PCI with stent implantation in Germany, and (ii) to identify factors associated with DAPT discontinuation during the recommended treatment period. Methods This retrospective cohort study was based on data from a large German electronic healthcare database of the years 2004 to 2009. The study population comprised four groups of patients with acute coronary syndrome (ACS) or stable angina pectoris undergoing inpatient PCI with either ba…

Effects of forest restoration treatments on the abundance of bark beetles in Norway spruce forests of southern Finland

2009

Abstract Restoration of protected areas in boreal forests frequently includes creating substantial volumes of dead wood. While this benefits a wide range of dead wood dependent invertebrate species, some of these are regarded as forest pests. Therefore, the risk of elevated levels of tree mortality in surrounding commercial forests must be considered. In a large-scale field experiment in southern Finland, we studied the effects of restoration treatments on the abundance of bark beetles within and in the vicinity of restored areas, in particular focusing on Ips typographus and Pityogenes chalcographus . The treatments applied to managed Norway spruce forests were controlled burning and parti…

Micro-investment perspective and the potential of the universal basic income

2018

In this article, we explore the prospects of Basic Income (BI) as a development policy tool. Our approach is to analyse the BI as a tool for promoting micro-investments and as a general development policy instrument, thus deliberately departing from the perception of cash transfers as targeted poverty reduction tools. As experiences in testing BI systems in developing country contexts are limited to local and regional experiments in Namibia and India (Haarmann et al., 2009; Haarmann & Haarmann, 2012; Davala et al., 2015), conclusive assessments about the impacts of the BI cannot be drawn. Therefore, we aim to estimate potential impacts of the BI by synthesising existing knowledge. This esti…

On the modelling of an Acid/Base Flow Battery: An innovative electrical energy storage device based on pH and salinity gradients

2020

Abstract Electrical energy storage can enhance the efficiency in the use of fluctuating renewable sources, e.g. solar and wind energy. The Acid/Base Flow Battery is an innovative and sustainable process to store electrical energy in the form of pH and salinity gradients via electrodialytic reversible techniques. Two electromembrane processes are involved: Bipolar Membrane Electrodialysis during the charge phase and its opposite, Bipolar Membrane Reverse Electrodialysis, during the discharge phase. For the first time, the present work aims at predicting the performance of this energy storage device via the development of a dynamic mathematical model based on a multi-scale approach with distr…

Power Grid Integration and Use-Case Study of Acid-Base Flow Battery Technology

2021

There are many different types of energy storage systems (ESS) available and the functionality that they can provide is extensive. However, each of these solutions come with their own set of drawbacks. The acid-base flow battery (ABFB) technology aims to provide a route to a cheap, clean and safe ESS by means of providing a new kind of energy storage technology based on reversible dissociation of water via bipolar electrodialysis. First, the main characteristics of the ABFB technology are described briefly to highlight its main advantages and drawbacks and define the most-competitive use-case scenarios in which the technology could be applied, as well as analyze the particular characteristi…

Different scenarios of electric mobility: Current situation and possible future developments of fuel cell vehicles in Italy

2020

The diffusion of electric vehicles in Italy has started but some complications weight its spread. At present, hybrid technology is the most followed by users, due particularly to socioeconomic factors such as cost of investment and range anxiety. After a deep discussion of the Italian scenario, the aim of the paper is to recognize whether fuel cell technology may be an enabling solution to overcome pollution problems and respect for the environment. The opportunity to use fuel cells to store electric energy is quite fascinating&mdash

Knowledge, attitudes, and practices about homelessness and willingness-to-pay for housing-first across 8 European countries: a survey protocol

2018

Contains fulltext : 200223.pdf (Publisher’s version ) (Open Access) Background: Most European countries report rising numbers of people experiencing homelessness. For those with mental disorders, interventions are centered on achieving mental health and drug rehabilitation alongside housing readiness, often to the detriment of access to housing. Notwithstanding, more European countries are investing in a new model, Housing First (HF), which postulates immediate access to permanent housing with no initial requirements for treatment. While results of the European HF programs are published on individual-level data, little is known about the opinions of the general population about homelessness…

Big Data and Antitrust Enforcement

2017

The interaction between information, innovation and market outcomes is shaping the modern digital industries of the 21st century: the business models of search engines, social networks, e-commerce websites and marketplaces are highly reliant on the ability to gather and process large amount of data. At the same time, it is increasingly recognized that the use of Big Data by online platforms and intermediaries has far-reaching consequences not only on economic activity, but also on social and political mechanisms: technological developments affecting information flows affect the organization of markets as well as the nature of individual interactions and the functioning of the political proc…

Non-Enzymatic Water-Soluble Antioxidants Bioanalysis in Some Teas and Juices by PCL Method

2011

Non-enzymatic water-soluble antioxidants from different teas (black, green, peppermint), coffee, natural extract of rosemary and fruit juices (apple, grape, grapefruit, kiwifruit) were quantized by measuring their chemiluminescence in order to establish their power to protect the living beings from the free radicals. Among the samples high values of antioxidative capacity presents green tea (655 mmol AU) (AU=ascorbic units) and kiwi fruit juice (31 mmol AU). The maximum measuring times are less than 3 minutes. The sensivity of the photo-induced chemiluminescence (PCL) method was very high: nanomolar concentrations of non-enzymatic watwer-soluble antioxidative substances, as ascorbic acid un…
