Lock-in as make-believe : Exploring the role of myth in the lock-in of high mobility systems

All human practices are, ultimately, set and defined by limits; be they social, economic, physical, or environmental. Yet even in the face of such realities, practices which transgress the confines of possibility remain remarkably obdurate. This thesis addresses the issue of one such practice, i.e. the escalation of personal mobility across time and space which pushes above and beyond systemic bou

Effectiveness of non-surgical periodontal therapy in a large Chinese population with chronic periodontitis

Aim: The aim of this study was to evaluate the effectiveness of non-surgical periodontal treatment (NSPT) and its influential factors in a large Chinese population with chronic periodontitis. Methods: Periodontal examination data of 10,789 patients with at least one periodontal re-evaluation record were extracted from a hospital-based electronic periodontal charting record system. Probing depth (P

Aligning Requirements and Testing : Working Together toward the Same Goal

The proper alignment of requirements engineering and testing (RET) can be key to software's success. Three practices can provide effective RET alignment: using test cases as requirements, harvesting trace links, and reducing distances between requirements engineers and testers. The Web extra https://youtu.be/M65ZKxfxqME is an audio podcast of author Elizabeth Bjarnason reading the the Requirements

Pubertal mammary gland development : Elucidation of in vivo morphogenesis using Murine models

During the past 25 years, the combination of increasingly sophisticated gene targeting technology with transplantation techniques has allowed researchers to address a wide array of questions about postnatal mammary gland development. These in turn have significantly contributed to our knowledge of other branched epithelial structures. This review chapter highlights a selection of the mouse models

Gene therapy for Parkinson's disease : Disease modification by GDNF family of ligands

Gene transfer is a promising drug delivery method of advanced therapeutic entities for Parkinson's disease. One advantage over conventional therapies, such as peripheral delivery of the dopamine pre-cursor L-DOPA, is site-specific expression of proteins with regenerative, disease-modifying and potentially neuroprotective capacity. Several clinical trials have been performed to test the capacity of

Wiring of Photosystem I and Hydrogenase on an Electrode for Photoelectrochemical H2 Production by using Redox Polymers for Relatively Positive Onset Potential

Photosystem I (PSI) is combined with Desulfovibrio gigas hydrogenase for the bioelectrocatalytic photosynthesis of hydrogen at an electrode surface. The activity of these two biocatalysts is linked by two redox polymers; a redox polymer with a relatively positive potential (loaded with an Os complex) is able to reduce PSI and thus facilitates the production of photoexcited electrons, whereas redox

Luminescence dating of aeolian–coastal events on the Kristianstad plain, SE Sweden

Aeolian–coastal sediments and landforms are excellent palaeoenvironmental archives, but chronological studies of coastal records are scarce in Sweden. In this study, we provide luminescence and radiocarbon ages of aeolian activity and coastal landscape evolution on the Kristianstad plain, SE Sweden, based on the investigations of two foredunes and two inland dunes at Åhus and Vittskövle. Additiona

Improved Greedy Nonrandomness Detectors for Stream Ciphers

We consider the problem of designing distinguishers and nonrandomness detectors for stream ciphers using the maximum degree monomial test. We construct an improved algorithm to determine the subset of key and IV-bits used in the test. The algorithm is generic, and can be applied to any stream cipher. In addition to this, the algorithm is highly tweakable, and can be adapted depending on the desire

Språkgemenskap, ny teknik och språkmöten

Artikeln diskuterar hur den nordiska språkgemenskapen påverkas av nutidasamhällsutveckling och framför allt av ny teknik. Denna påverkar våra språkmöten både på modersmålet och i det nordiska sammanhanget. Artikeln fokuserar på hur förändringarna påverkar våra språkmöten (i tal), och jag driver tesen att den nya tekniken på många punkter innebär tätare språkmöten med personer som vi redan känner o

One event, three investigations : The reproduction of a safety norm

Following an adverse event in a Swedish university hospital in 2010, three separate investigations seeking causal factors were conducted. We here review each of the analyses to see whether they together generate the kind of epistemological pluralism that could contribute to a systemic understanding of, and learning from, the event. Our content analysis shows that, while using vastly different amou

Information, trust and diffusion of smallpox vaccination : the case of Scania, Sweden 1802-1835

This study deals with the diffusion of a new medical technology — vaccination against smallpox — in nineteenth-century Scania in Sweden. Using an aggregated sample of parishes as well as a micro-level dataset for four parishes, we investigate the socioeconomic as well as the geographical patterns of diffusion of vaccination in the province. We also relate the adoption of vaccination across geograp

An obligatory role for neurotensin in high-fat-diet-induced obesity

Obesity and its associated comorbidities (for example, diabetes mellitus and hepatic steatosis) contribute to approximately 2.5 million deaths annually and are among the most prevalent and challenging conditions confronting the medical profession. Neurotensin (NT; also known as NTS), a 13-amino-acid peptide predominantly localized in specialized enteroendocrine cells of the small intestine and rel
