Hemicelluloses account for 25-30% of total wood dry weight. Mannan-based polysaccharides are the major component of softwood hemicelluloses. They are characterized by their β-1,4-glycosidic linked backbone composed of mannose or a combination of mannose and glucose residues. The backbone can be substituted by α-1,6-linked galactose residues. β-mannanases cleave the internal β-1,4-glycosidic bonds

The changing of the climate is today a problem. There are many reasons why the climate is changing but one of the biggest is the use of cars for personal transport. To reduce the emissions of climate gases many cities in Sweden are today planning for sustainable transports instead of the car. Examples of sustainable transportation is public transport and biking. Although the bike is a good vehicle

VAD HAR DEN SOCIALA HÅLLBARHETEN MED KLIMATUTMANINGARNA ATT GÖRA? Frågan låter mer disparat än vad den egentligen är. Forskning och praktik visar att det finns en direkt kausalitet mellan de två. Att ett fokus på social hållbarhet kan förbättra relationen till hur vi uppfattar och hanterar klimatutmaningarna men också ge direkta återkopplingar. Det går inte att utesluta att med en utökad kunskapsToday, the concept of sustainability is central in several housing projects, not to mention the many other socio-technological projects for which the concept is a directive. In this study I problematize the relation of the paradigm of sustainable development to one of its main “pillars”, the social dimension, and how this can relate to the greatest challenge of our generation – climate change. As

Det svenska folkbiblioteket som institution är under förändring. Utlånen minskar då material nu är tillgängligt för användare hemifrån via internet. Däremot används biblioteksbyggnaderna fortfarande till en rad olika ändamål. Det är en plats på för studier för många olika målgrupper och många bibliotek har inrättat lärcentrum för vuxna. Barn och ungdom är en viktig grupp eftersom bibliotek är en The Swedish public library as institution is under change. Library loans is steadily decreasing because content is now accessible for users at home via the internet. However, the library building is still being visited for a wide variety of purposes. It is a place for study for all age-groups and many libraries provide learning spaces for adults. Children and youth are important groups because th

This thesis is about the political party the Sweden democrats and its ideological residence, trying to answer the question whether it’s correct to define it as fascist or not. Very little previous research has made a deeper analysis into this which makes this study both more interesting and more important. There is a lack of consensus about the definition of fascism among scholars, and especially

The number of machine-type communications (MTC) devices is predicted to increase enormously in the near future, and this increase is expected to be accommodated by 5G. However, the Authentication and Key Agreement (AKA) mechanism used in the fourth generation of mobile telecommunications systems, EPS, may prove too inefficient for handling a large number of MTC devices simultaneously trying to con

Machine control with GPS allows machinists to operate using a digital model as reference instead of the traditionally used methods. This leads to other duties and a different flow at the worksite. The purpose of this study is to examine how various professions have changed with the development of machine controlled equipment and also how the work methods can be optimized. A series of interviews ha

Flexilast is a company located in Eslöv that provides trucking and construction services. To order or get help with goods and services from the company today, you would have to call them. The employees at the company spend alot of their time on the phone to help customers with the company's various products and services. To solve these problems Flexilast contacted Daniel Hurtig and Tom Hansson

This study makes a numeric and visual comparison of two different multibeam echo sounding (MBES) surveys performed at the exact same location, in an effort to establish how reliable and comparable the vertical depth measurements are. The horizontal position uncertainty is not issued in this study. The analysis was performed on data delivered by two survey contractors, The Norwegian Coastal Admini

Bakterier stjäler det mänskliga proteinet plasminogen och utnyttjar det till sin fördel Människokroppen använder särskilda sätt för att överleva och skydda sig mot yttre hot, som bakterier. Bakterier har i samma takt utvecklat mekanismer för att stjäla kroppens proteiner och på så sätt utnyttja människans egna försvarsmekanismer för att ta sig in, sprida sig, och göra kroppen sjuk. Pseudomonas ae

The Malmo Central Station Starbucks opened in 2012 as one of the first Starbucks shops in Sweden. The shop works as a transient location, skillfully designed around its train station location and historical aesthetic. It here functions as one of Starbucks’s first forays into coffee- and fika-minded Sweden, where it must balance appealing to Swedish customers who are new to the brand and internatio

Klimatet under Kvartärperioden har dominerats av återkommande istider, då bl.a. Skandinavien och Sverige varit täckt av inlandsis. Vid analysen av långsiktig säkerhet för det planerade förvaret av använt kärnbränsle, i Sverige, behöver tider på upp till en miljon år beaktas. Under denna mycket långa tid förväntas nya nedisningar komma och därför utförs ett forskningsprogram på Grönland för att ökaDuring the Quaternary period, the climate has been dominated by glacial cycles resulting in periodic ice sheet coverage over Scandinavia and Sweden. In the scenarios for future climate development used in the assessment of long-term safety for planned repository of spent nuclear fuel, the possibility of future glaciations need to be considered. The present study is part of a larger hydrological st

This master thesis aimed to evaluate the possibilities of inhibition of Lactobacillus plantarum 299v metabolism of malate by introduction of lactic acid in ProViva apple drinks. The malate metabolism of L. plantarum have been found to promote an overproduction of carbon dioxide in ProViva apple drinks and thereby the metabolism was tried to be inhibited. The experiment included three different con

This thesis explores the extent to which international human rights law and international labour law place obligations on States to protect migrant workers’ fundamental rights, especially their rights to social security. More importantly, this thesis examines intra-ASEAN migrant workers’ accesses to the social security benefits, as defined by the ILO Social Security (Minimum Standards) Convention,

With a steady development of technology, the use of Model Predictive Control (MPC) has become more and more popular since the computation time has gone down. With this increase, a need for determining which MPC algorithm is good for solving a certain type of MPC problem has occurred which would facilitate the choice of algorithm and also could increase the performance. One of the determining aspec

Background: Risky sexual behaviours have been shown to increase among HIV positive people. Little is still known about the risky sexual behaviours of ART naive as there is more focus on patients already enrolled on ART. This study explores potential behavioral disinhibition among patients enrolled on ART in comparison to patients not yet enrolled on ART and assesses the impact of ART on risky sexu

The Japanese language has a complex system containing four different scripts. Through the combined usage of these scripts into something sometimes referred to as interlinear glossing, it is possible for the writer to express a wide range of poetic styles in a way that is quite unique to the Japanese language. Ranging from metonymical relations between words and sentences, to synecdoche, word play

‘Smiling in your brother’s face is an act of charity’; said prophet Muhammad (ALLAH’s peace and blessings be with him). Amelogenin (Amg) is one of the most important proteins that are responsible for perfect tooth formation giving us that beautiful smile. Amelogenin has multifunctional characteristics like wound healing, cells proliferation induction, anti-inflammatory, anti-infectious and signal
