Market forces and legislation push the recovery of used material as part of developing a sustainable society. Materials made of forest fibres have the advantage compared to other materials that they are easy to recycle. It saves resources. Production of paper based on used fibres uses also less energy than paper containing new fibres. The market focus on recovery makes it a reasonable assumption,
Background Transcriptional regulation of the genes in metabolic pathways is a highly successful strategy, which is virtually universal in microorganisms. The lac operon of E. coli is but one example of how enzyme and transporter production can be made conditional on the presence of a nutrient to catabolize. Methodology With a minimalist model of metabolism, cell growth and transcriptional regula
Recent clinical trials have pioneered the successful use of a nonsteroidal immunosuppressive regimen and established a basis for application in a routine clinical setting. In this study, a single islet transplant was not sufficient to regulate blood glucose levels, and a second transplant became necessary. A similar observation was made in our macaque islet transplant study, where animals after th
Det är allmänt känt att kontinenter under Jordens historia har separerat och kolliderat i ett cykliskt förlopp vilket har lett till existensen av större landmassor, superkontinenter eller superkratoner under vissa tidsperioder. En av de tidigaste föreslagna superkratonerna är Vaalbara, som sedan 1960-talet har ansetts bestå av Kaapvaalkratonen i södra Afrika och Pilbarakratonen i västra AustralienIn this thesis, the longevity and continuity of the Vaalbara supercraton is addressed in six papers aimed at placing new temporal and spatial constraints onthe supercraton in the Mesoarchean to Paleoproterozoic. It has been speculated since the 1960’s that the Kaapvaal Craton in southern Africa, together withthe Pilbara Craton in Western Australia existed as a single landmass during the Precambria
To combat climate change, different types of initiatives and policy instruments are required to support the development and dissemination of new energy efficient technologies. What type of policy instruments shall be used is, however, not pre-determined. To advance knowledge in how to design successful policy instruments, evaluations and deep-analyses are needed; this to better understand the role
When a child has special communication needs, his or her entire family is affected. This position paper deals with “Xings” (crossings or just xings): active and reactive multisensory media, designed to be communicative on their own terms, challenging existing everyday communication patterns and augmenting family communication. The common shortcomings of oral and written language are no longer crit
New theoretical developments in impurity lattice dynamics are presented, with the emphasis on phonon broadening of core levels in metals. Detailed calculations have been made for Li and Na. The effects of non-linear screening are evaluated for the first time and are shown to increase the phonon broadening by about 70% for Li compared with the linear-screening value. The present a priori estimate o
Abstract in UndeterminedIn the humanitarian context, gender mediates access to aid. The gender of the beneficiary is not only intrinsically linked with her/his disaster vulnerability (Enarson, 2002), but also to their ability to physically access aid distribution points (Lutz and Gady, 2004) and even to be considered a beneficiary in the first place. There is, however, yet another factor mitigatin
WLANs based on IEEE 802.11 are becoming more and more popular both in commercial and residential settings. However, the very success of 802.11 may become a threat to the technology itself. Since there are only a limited number of non-overlapping channels available in the IEEE 802.11 WLAN standards, this can lead to interference among WLANs in dense areas. In this paper, we investigate the effects
This paper discusses the possible advantages and disadvantages by using experimental methods in order to understand how music influences our understanding of film narratives. Can experimental and quantitative methods such as eye tracking, questionnaires, galvanic skin response, EEG (electroencephalogram) and fMRI (functional magnetic resonance imaging – a brain scan) give us insights into the sign
While high levels of glucose and saturated fatty acids are known to have detrimental effects on beta cell function and survival, the signalling pathways mediating these effects are not entirely known. In a previous study, we found that ADP regulates beta cell insulin secretion and beta cell apoptosis. Using MIN6c4 cells as a model system, we investigated if autocrine/paracrine mechanisms of ADP an
Recently several distinct literatures have thematically converged around the topic of non-European state-making: political scientists – both comparativists and international relations scholars, historical sociologists, comparative and world historians, anthropologists, archaeologists and others, have begun to interest themselves in state making or state formation in non-European settings, and also
Since thermal loads can cause cracking, they are important to consider in bridge design. In order to evaluate and develop thermal load cases based on real simulations, models for simulating temperatures can be used. In this paper, a model for thermal simulation is used to simulate temperature in a portal frame bridge outside Lund, Sweden. The results are compared with temperature measurements in 1
Achieving ambitious international energy-saving targets calls for more powerful instruments and will entail changes both in society as a whole and for individual actors. Besides developing increasingly efficient technology, the field of energy behaviour holds the greatest potential of energy conservation. This contribution considers households and how technology and design can support them in both
This paper presents a cryptographic processor compliant with the security algorithms specified by the 3rd Generation Partnership Project (3GPP) specifications for Long Term Evolution (LTE). The proposed processor has been adapted to the needs of the low end portfolio technologies that compose the Internet of Things (IoT) market, which addresses low-Area, low-cost and low-data rate applications. Th
The starting point for this inductive study is to determine, through a search of studies, what critical viewpoints in terms of research are delivered, based on experiences, observations and evaluation, concerning the Bologna Process over time? The aim is to present a description using a thematic analysis based on data from 38 papers (2004–2016) that reveal the critical reasoning behind the researc
Delegated, but still intensive: Quality time and parenting in upper-middle class families in Sweden During the last decade, Swedish families have started to employ nannies and au pairs to an extent previously never experienced. Political initiatives such as tax deductions for household services, together with global trends of ‘care chains’, have created a private market for care services, which ha
Tests were done measuring resistivity and time domain induced polarisation using standard multi-core cable spreads and a special layout with separate cable spreads for transmitting current and measuring potentials. For both types of cables spreads both normal and reciprocal measurements were done in order to estimate the measurement errors. The tests were done on a former landfill in Lund in Swede
Gender assignment in languages with a gender system is a complex issue, as this can be influenced by both semantic, morphological, and phonological factors (Corbett, 1991, 2013; Corbett & Fraser, 2000). Many Indo-European languages possess a three-gender system, which distinguishes masculine, feminine, and neuter gender. Whereas this system is preserved in several Indo-European branches, it ha
Chimeras have been an important part of animal research for decades. Yet crossing the species barrier has always been seen as potentially morally problematic. In recent years, advances in chimeric research and the attendant possibilities—organ xenotransplantation, cognitive enhancement, and others—have given rise to further ethical concern. This contribution surveys the main ethical questions that
