BackgroundWe aimed to evaluate if optimization by maximizing QRS duration (QRSd) reduction is feasible in an all-comer cardiac resynchronization therapy (CRT) population, and if reduced, QRSd is associated with a better clinical outcome.MethodsPatients with LBBB receiving CRT implants during the period 2015–2020 were retrospectively evaluated. Implants from 2015–2017 were designated as controls. S
17th European Research Conference on HomelessnessLeuven, September 14th and 15th, 2023Marcus Knutagård, Arne Kristiansen & Cecilia HeuleRECO: Resilient Communities by Sustainable Welfare TransformationHomelessness is an extensive societal problem in Sweden which poses major challenges for the social services in developing sustainable and effective methods that can meet the service user’s needs
An increasing demand for energy-efficient buildings has led to an increasing focus on predicted energy performance once a building is in use. Many studies have identified a performance gap between predicted energy use and actual measured energy use once buildings are in the user phase. However, none of the identified studies normalise measured energy use for both internal and external deviating bo
The voluminous literature on industrial catching-up in Southeast Asian countries has regularly argued that successful catching-up largely depended on a committed state, which orchestrated industry development with a relatively uniform set of policies, including R&D support, subsidies, trade restrictions, and local content requirements. In contrast, recent contributions from the technology life
The world faces major climate challenges and extensive efforts need to be taken to combat this issue. Replacing fossil-derived fuels and chemicals with renewables are one important step on the way. Hydrogen has a great potential as a renewable energy carrier for the transport sector and as a green chemical for the industry. Today, the production of hydrogen stems primarily from fossil resources. A
Peak oil has acquired prominence in the political lexicon of an increasing number of critical and radical perspectives during the ongoing ecological and economic crisis. By examining examples within academia as well as initiatives such as the Degrowth Movement and the Transition Network, this paper documents how a series of red-green discourses and movements mobilise the narrative of peak oil as a
Wheat straw is an abundant, cheap substrate that can be used for methane production. However, the nutrient content in straw is inadequate for methane fermentation. In this study, recycling digestate liquor was implemented in single-stage continuous stirred tank processes for enrichment of the nutrient content of straw with the aim of improving the methane production. The VS-based organic loading r
Despite the recent surge of wind and solar power, both technologies need to accelerate to meet climate goals. Yet, there are no robust methods to assess the likelihood of such acceleration. Here we show that renewable energy deployment follows a recurring pattern across countries with prolonged periods of relatively steady growth punctuated by growth pulses. Based on this insight and on observed g
The sector of residential buildings and service organizations uses 36% of the total energy in Sweden. In June 2006, it was decided by the Swedish parliament that the energy use in residential buildings and premises should decrease by 20% per heated unit area before 2020. To reach this goal, more energy efficient buildings must be produced as well as energy efficient improvements must be performed
The studies presented here have shown that it is fully possible to influence energy consumption through information. An increase in the knowledge among consumers will motivate them to be more energy efficient. Since several interrelated factors are involved in this knowledge level, it is difficult to establish the individual influences but such factors as the electricity bills, electricity meterin
The process simulator ASPEN PLUS was used for simulation of an ethanol production process based on enzymatic hydrolysis of lignocellulosic materials. Various process configurations were studied to increase the overall yield of ethanol and to reduce the energy consumption in the process. An increased utilization of the pentosan fraction was achieved by a complex recycling of streams in the process.
A total of 47 firms joined the Swedish EKO-Energi programme between 1994 and 1997. This was a public voluntary programme devoted to promoting the environmental vanguard, while disregarding the rearguard. The programme offered free energy audits and the promotion of a label, in return for implementation of energy management. Audits covered some 5% of industrial energy consumption. The most clearly
In order to contribute to knowledge on how-to expand bioenergy this paper examines an example of success from Sweden. The idea is to identify factors that can explain the difference between success and failure of bioenergy systems. In the aftermath of the oil crises in the 1970s, the local government in the town of Enkoping in Sweden was cautioned by the local Swedish military regiment to shift to
Long term evaluation of an asymmetric CPC PV-thermal hybrid built for high latitudes, MaRcCo (MaximumReflectorCollector), is performed in Lund, lat 55.7 degrees, and this paper discusses output estimates and characteristics of the system. The output estimates are calculated using the MINSUN simulation program. To get the input for MINSUN, measurements were performed on two MaReCo prototypes. These
The paper discusses the results of a time dynamic analysis of the possible effects of government and utility sponsored energy efficiency programmes on lighting energy use in Sweden. Scenarios are developed of electricity demand and efficiency improvement, based on various types of energy performance standards and utility demand-side management (DSM) investments. The scenarios account for the dynam
One of the most important research interests in the field of organic photovoltaic devices (OPVs) is the development of new materials which can serve as light-absorbing electron donors and hole-conducting (p-type) semiconductors. In this context, 1,3-polyazulenes were synthesized chemically and electrochemically. Their spectroscopic and electrochemical properties are compared with those of the 1,3-
Regulations to promote the application of renewable energy in the electricity sector are crucial to achieve the government’s target of increasing the share of renewable energy to 10 TWh within 10 years. Feed-In tariffs provides the highest certainty to accomplish a significant growth of renewable energy since it provide high certainty to investors and are easy to implement. For the design of a Fee
