Two well dated Holocene sediment records bordering the Denmark Strait region have been used to reconstruct past climate variability. The content of biogenic silica, clastic and organic material and moss in a lacustrine record from Lake N14 has been used to infer past variability in precipitation and temperature in southern Greenland. Sedimentologic and petrologic composition of sand in a shelf sed
Product concentrations may be estimated from gas analysis or calorimetric measurements. These techniques of analysis are fast, simple, and provide a continuous output. To check the accuracy of these estimations, the anaerobic ethanol formation of an industrial strain of the yeast Saccharomyces cerevisiae was selected as a test system. Cultivations were carried out as batch cultures with different
Context. Development of safety-critical systems is mostly governed by process-heavy paradigms, while increasing demands on flexibility and agility also reach this domain. Objectives. We wanted to explore in more detail the industrial needs and challenges when facing this trend. Method. We launched a qualitative survey, interviewing engineers from four companies in four different industry domains.
This article addrsses the advant of this online only publication, the very context in which it is being made available. Central to this article is Delanty's work on communicative communities. It is argued that it is particularly appropriate to view comparative and international education in this manner. Online publication offers comparative and international education a new context of meaning. See
Derivatives of N-acetyllactosamine carrying structurally diverse thioureido groups at galactose C3 were prepared from a C3'-azido N-acetyllactosamine derivative in a three-step reaction sequence involving azide reduction and isothiocyanate formation by thiophosgene treatment of the C3-amine, followed by reaction of the isothiocyanate with a panel of amines. Evaluation of the N-acetyllactosamine th
Shed mediastinal blood collected by cardiotomy suction has been shown to be a large contributor to lipid microemboli ending up in different organs. The aim of this study was to test the separation efficiency on human shed blood of a new separation method developed to meet this demand. METHODS: Shed mediastinal blood collected from the pericardial cavity of 13 patients undergoing cardiac surgery wi
The paper addresses an optimization problem related to dimensioning links in a resilient two-layer network. A particular version of the problem which assumes that links of the upper layer are supported by unique paths in the lower layer is considered. Two mixed-integer programming formulations of this problem are presented and discussed. Direct resolving of these formulations requirespre-selection
ABSTRACT: Presence of a cervical rib in children is extremely rare, particularly when symptoms of compression of the lower trunk of the brachial plexus occur. We present two cases with such a condition, where two young girls, 11 and 16 years of age were treated by resection of the cervical rib after a supraclavicular exploration of the lower trunk of the brachial plexus. The procedure led to succe
A low phase noise CMOS LC quadrature VCO (QVCO) with a wide frequency range of 3.6-5.6 GHz, designed in a standard 0.18 /spl mu/m process for multi-standard front-ends, is presented. A significant advantage of the topology is the larger oscillation amplitude when compared to other conventional QVCO structures. The QVCO is compared to a double cross-coupled LC-tank differential oscillator, both in
The public sphere and public reason have recently become key ideas in global governance, with most scholars expressing related transparency and accountability concerns. This article contends that if transnational public sphere(s) and the use of reason in global policy-making aim to reinforce the common good and justice, they must go beyond the procedural concerns of transparency and accountability
The feeling of being unsafe in the city creates restrictions in many people's lives. The urban environment has an impact on the perception of safety and the municipality can through their work with the urban design affect the safety. This thesis analyzes a form of citizen participation in urban development, called safety walks. The aim of the study is to examine in which ways safety walks may
Understanding affordance is a bottom-up process that lets simple visual features be used as clues on how to use an object, so that reasonable interactions with objects can be achieved, without any semantic knowledge. Linear splines are proposed as a way for robots to fast and continuously learn how their actions affect their surroundings. The general conclusions that they can draw from only little
This is a bachelor thesis about fisheries and harbor seals on the west coast of Sweden. This study scrutinizes the relationship between them both and appropriate solutions to get a good interaction between fishermen and harbor seal. A qualitative method was best suited for the study as it aims to investigate the perceived reality of fishermen that exists in our surroundings. The study is based on
Populist parties in Europe are and have been emerging in the last decade in a fast pace. The populist rethoric is becoming more and more common. In Sweden this is also the case, as the populist party Sverigedemokraterna quickly has become the third largest party in the country. The party-leader, Jimmie Åkesson, is a good rethorician. Åkesson and his party has been a hot-topic in media and society
The demand for rare earth elements (REEs) is growing, while the future supply is uncertain. Their unique electronic characteristics make them irreplaceable, and the commercial value of pure fractions is high. A model-based simulation study is presented that compares batch chromatography with the twin-column MCSGP (multicolumn countercurrent solvent gradient purification) process for ion-exchange c
Abstract in UndeterminedThe Doughnut fallacy hypothesis posits that many debaters tend to sup- port their arguments using collapsed generalities – such as “democracy” – with pur- ported self-evident positive or negative qualities as philosophical grounding. This will leave an often unexamined hole in the middle of the debate which will stunt delib- erative processes, as it effectively stops delibe
