Pappers- och pappersmassaindustrin har ökat markant under de senaste årtiondena. På grund av att samhället har blivit mer miljömedvetet har återvinning av papper blivit en allt viktigare del inom industrin. Återvunna pappersfiber är dock av lägre kvalité än nygjorda fibrer. Syftet med denna rapport är att analysera möjligheterna att använda ett enzym av typen lackas för att modifiera interaktionenThe pulp and paper industry have been a growing market during the last decades. Due to higher environmental concerns among people, the recycling of papers has become an even more important part of the industry. Recycled paper fibers however are of lower quality than virgin fibers. This report aims to analyze the possibility to use a laccase enzyme to modify the interaction between lignin and recyc

For decades, the use of elevators has been prohibited during emergencies but with the ever-increasing heights of the buildings, safe and timely vertical evacuation by the conventional means of stairs seems more and more of a challenge. With the recent push for a better understanding of the pros and cons of use of elevators for evacuation by various concerned parties, it is imperative that there is

Digitalization has grasped almost every aspect of work in Norway in similarity to the developed world. Although many advantages are followed with the implementation of digital tools to bolster the work effort, there is a widespread downside, technostress. This phenomenon engulfs large parts of the workforce and poses a challenge for any foreseeable future, and there is a general lack of research a

The present research aims at finding the underlying factors that contributed to the recently observed disappearance of economic shrinking in Ethiopia, defined as negative rates of GDP per capita growth. Within the framework of the Theory of Shrinking (Broadberry & Wallis, 2017) it sheds light on structural, technological and demographic change, the occurrence of warfare as well as institutiona

When producing printed circuit boards, end of line testing needs to be done to assure that as few faulty products as possible reach the customer. This can be done manually, but takes long time. By using a Functional Test fixture (FCT-fixture) it is possible to do the test faster and at a lower cost. A FCT-fixture is a fixture with a lid where the printed circuit board is placed. When the lid is cl

I den här masteruppsatsen undersöktes geokemin i kalkskalen av bottenlevande foraminiferer från Anholt (Kattegat), Ristinge (Bälthavet) och Obrzynowo (Egentliga Östersjön), för att rekonstruera de hydrografiska förhållanden i Östersjön och paleomiljön under den senaste interglacialen (130 - 115 ka BP). De variabler som analyserades innefattade Mg/Ca, Ba/Ca och Mn/Ca samt stabila syre- och kolisotoIn this thesis, three microfossil records from Anholt (Kattegat), Ristinge (the Danish straits) and Obrzynowo (the southern Baltic- coast) representing the last interglacial Eemian (130- 115 ka B.P) were generated. The geochemistry of benthic foraminifera was investigated to reconstruct the Eemian Baltic Sea hydrography and paleoenvironment. The paleo-environmental proxies were: the trace elements

In the last decades Peru, one of the top performing countries in Latin America, experienced a dramatic reduction in poverty. The set of structural reforms implemented by Peru during the mid-90s included trade liberalisation which implied a drastic reduction of tariffs on highly protected sectors, and particularly, in agriculture where most poor Peruvians work, and Free Trade Agreements. How relati

During the years of the so-called refugee crisis, migrants lacking access to housing in Greece have squatted buildings or resided in makeshift settlements. Those homes have been met with state violence and continuous evictions. Those evictions are a form of migration control in the context of an ongoing disciplinary ‘management’ of migrant populations and their mobility in Europe and Greece. The t

Climate changes have a large impact on precipitation patterns and precipitation variability change. With this in mind, precipitation over Greenland is studied. This is done for present day precipitation model data from 1991-2010 compared to future model simulations of precipitation for 2081-2100. Furthermore, precipitation drives Surface Mass Balance (SMB), which is the sum of accumulation and the

Skydd för kulturarv under internationell rätt introducerades i internationella konventioner i början på 1900-talet. Ursprungligen behandlades ämnet uteslutande i förhållande till regler gällande väpnad konflikt. Frågor om kulturarv har traditionellt sett tillhört den nationella jurisdiktionen men framväxandet av idén om ’världsarv’, kulturarv som på grund sitt värde tillhör alla folk och nationer,The protection of cultural heritage first appeared in international conventions at the beginning of the 20th century. At the time, protection was only awarded in the event of an armed conflict. Traditionally, questions of heritage and its eventual destruction belonged within the national jurisdiction but the emerge of internationalist ideas of a ‘common heritage of mankind’ changed the perception.

Uppsatsens syfte var att undersöka hur ICJ influerar internationell rätt som legal normsättare till det internationella samfundet. Frågeställningen var: hur konceptualiseras idén om ICJ och dess värde för det internationella samfundet av FN:s generalförsamling och domarna som dömde i samband med kärnvapensrådgivningen? Primärmaterialet utgjordes av valda sektioner i de åtta resolutionerna från FN:

The news media remains as one of the most important sources of societal uptake of climate change information. Its potential to covertly shape public perception and attitudes regarding climate change is therefore considerable but difficult to assess. This thesis underscores the discursive and cognitive role of metaphor in this dynamic by using a framework that combines the theory of conceptual meta

Bergslagens malmprovins är känd för att innehålla stora Zn-Pb-Ag- och Zn-Pb-Cu-Ag-sulfidförekomster med tillhörande järnoxidskarn och många studier har fokuserat på att förstå dessa förekomster. Cu-Co-förekomster som Vena-Dampetorp-förekomsten har emellertid fått mindre uppmärksamhet. Vena-Dampetorp-förekomsten är en disseminerad och åderstödd Cu-Co-mineralisering som förekommer i en 1,89 Ga ryoliThe Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. The Vena-Dampetorp deposit is a disseminated and vein Cu-Co mineralization hosted primarily in a 1.89 Ga rhyolitic to

China experienced a growing economy with a huge market and business potential and became the second biggest country in terms of GDP. However, because of the limitation of coherent business laws and government supervision, entering the Chinese market became a severe and complicated problem for different kinds of firms. Empirical papers show that networks, called guanxi in China make a primary contr

Previous numerical investigations have simulated the delamination of paperboard using various mechanical and cohesive models. This has given satisfactory agreement between the simulation results and experimental data when comparing force-depth curves during creasing and moment-angle curves during folding. However, the simulation results are dependent on the user’s definition of the delamination zo

Yogurt is an ancient food, used for a better preservation of milk. Milk gets fermented by Streptococcus thermophilicus and Lactobacillus bulgaricus (lactic acid bacteria, LAB) which converts the lactose present in the milk to lactic acid. These probiotics support the microbial population balance of the gastrointestinal tract. Sweet potato, Ipomoea batatas, is an important security crop in developi
