Blood compatibility of biomaterials made of recombinant spider silk
Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application.
When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation.
The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions.
Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense.
Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials.
This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating.
Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films.
Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

Reaktionerna på Tage Erlanders metalltal : En analys av aktörers identitet och intressen
The Swedish Prime Minister, Tage Erlander, made a speech on the 22 of August 1961 in which he dismissed speculation that Sweden was seeking to abandon its neutral stance and non-alignment in foreign policy with a view to requesting membership of the European Economic Community. The reason was that the EEC was supposed to have a political part where a connection with NATO should have existed. This speech led to a domestic discussion which has been called the most intense debate of foreign affairs in recent history. The purpose of this paper is to analyse the reactions of the other parliamentary parties to Erlander?s speech.
KRAV OCH MÖJLIGHETER FÖR STYRNING AV VATTENFALLS VATTENKRAFTSTATIONER
The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.

Suveränitet eller mänskliga rättigheter? : En idéanalys om USA:s rättfärdigande av Operation Iraqi Freedom
AbstractAs human beings, we are all governed by our innate instinct that to kill another human being, or to just inflict pain on another, is to go against what makes us human. Still, it happens every day, far and near. Some of these killings happens in war-like situations, where atrocities against humanity occur. The international community has since the founding of UN in 1945, a duty to intervene where crimes against the human rights occur. This is a difficult task, because, in order to intervene and help those in need, the situation might postulate states violating states sovereignty.

The Toyota Production System (TPS) : ett verktyg för att skapa effektiv och lönsam produktion
Many companies are currently working to optimize and streamline their processes and production lines to achieve higher profitability. In increasingly competitive markets, companies are working to find solutions to increase the value of their production with such a small use of resources as possible.
A tool used to accomplish this is the Lean management system. Lean comes from the production system that Toyota has been developing since the early 1900's, The Toyota Production System (TPS). The Lean philosophy helps companies, by working towards continuous improvement in its operations, to achieve higher customer satisfaction, more efficient production and ultimately higher profitability.
Many companies are working to implement Lean in their organization. But there are many who fail to implement a complete change towards Lean.
Blandad momsverksamhet : En flerfallstudie som jämför verkligheten med teorin
Mervärdesskatten infördes i Sverige den 1 januari 1969 med lagen (1968:430) om mervärdeskatt, så kallad moms. År 1994, året innan Sveriges inträde i EU, infördes Mervärdesskattelagen (1994:200) som anpassats till EG-rätt. Mervärdesskatten är alltid 25 procent om inget annat anges. Kunderna betalar moms till företaget och företagaren betalar in skillnaden mellan utgående moms och ingående moms till Skatteverket. Många företag bedriver blandad verksamhet, det vill säga både momsfri och momspliktig verksamhet som berättigar till avdrags- eller återbetalningsrätt av mervärdesskatten.
Rykte & dåliga betyg : Fallet: Jordbromalmsskolan
