Telephone service in Argentina has since its beginning been characterized as one of the most developed in South America. Regarding its development, two distinct periods can be identified. An initial period of private ownership extended from 1878 to 1946. In 1946, when the largest telephone company was bought by the state, a period of predominant state-ownership began that lasted until 1990 when th
Popular Abstract in Swedish Kristna, speciellt de av icke-judisk ursprung, som under det första århundradet drog sig undan aktiv medverkan i de traditionella grekisk-romerska kulterna och som i grekisk-romersk kontext kom att identifieras som utövare av något annat än traditionell judendom hamnade snart i ett socio-politisk dilemma. Å ena sidan skapade de tidiga kristnas fria hållning till den judWhen first-century gentile Christians withdrew from the traditional and civic Graeco-Roman cults and increasingly began to be identified by the Romans as not belonging to mainstream or common Judaism, they soon found themselves pressed "between synagogue and state." On the one side, the fact that they did not observe the Torah elicited hostility from Jews who did not want to be identified with a m
Popular Abstract in Swedish Denna avhandling tillhör området professions- och skolutvecklingsforskning. Avhandlingen tar upp hur förskolepersonal konstruerar sig som professionella subjekt, dvs hur förskolepersonal skapar sitt professionella jag, sin identitet, utifrån individuella såväl som kollektiva erfarenheter. Avhandlingen tar också upp på vilket sätt reflekterande samtal bidrar till denna sA major aim initially was to create a forum for reflective dialogue on the preschool professions and how it is experienced on a daily basis, so as to be able to investigate how members of the preschool staff construct their professional subject. The following are major questions that were posed: How do preschool staff members talk about themselves, their profession and their work? In what way does
A study of existing organic waste types in Malmo, Sweden was performed. The purpose was to gather information about organic waste types in the city to be able to estimate the potential for anaerobic treatment in existing digesters at the wastewater treatment plan (WWTP). The urban organic waste types that could have a significant potential for anaerobic digestion amount to about 50 000 tonnes year
In this study we approach the recent decline in income inequality in Latin America from the perspective of structural change with a focus on the relative performance of the agricultural sector. Our focus is on the underlying forces implied by Kuznets (1965). We zoom in on the relative performance of agriculture in the development process and the rural-urban duality and pay particular attention to
Popular Abstract in Swedish Från början användes uttrycket "mannen i ledet" bara om meniga soldater, men det är också ett bildligt uttryck med innebörden gemene man, gräsrot, medlem på fältet/gräsrotsnivå/verkstadsgolvet. Den här avhandlingen handlar om unga män som under mitten av 1990-talet gjorde lumpen på ett pjäskompani vid Wendes artilleriregemente i skånska Hässleholm. ”Pjäs” betyder kanoneThis dissertation deals with young men who in the mid 1990s made their military service at a cannon company at Wende’s artillery regiment in the scanian town Hässleholm. ”Cannon” refers not only to cannons, but also to haubitses, grenade-throwers and other heavy arms. The focus, however, is on cultural and social aspects of everyday military service. What does actually happen in the encounter betw
Popular Abstract in Swedish Kliniska och experimentella studier av kortisonallergi Kortisonämnen har använts sedan 1950 talets början för att behandla olika hudsjukdomar såsom eksem och psoriasis. Redan 1959 kom de första rapporterna om kontaktallergi mot hydrokortison, ett kroppseget kortisonämne. Senare studier har visat att 4–5 % av alla patienter som allergitestas med så kallat lapptest (epikuCorticosteroids are anti-inflammatory and anti-proliferative substances that also can induce sensitization, mainly through skin contact. In a sensitized individual, it can be hard to disclose the contact allergy at patch testing because the anti-inflammatory effect may mask the allergic contact reaction. This is primarily seen when patch testing to potent corticosteroids is performed and the readi
Popular Abstract in Swedish Skogs- och pappersindustrin är några av Sveriges mest betydande industrier. Mycket av det producerade pappret används till förpackningar och papper har under lång tid varit det dominerande materialet i förpackningsindustrin; en annan viktig industri i Sverige. På senare år har dock pappersindustrin utsatts för hård konkurrens från plastindustrin när det gäller material The paper and packaging industry is a major and important industry in Sweden. The industry is capital intensive with a large investment base and long cycles for renewal and replenishment of machine platforms and other production equipment. Thus, the paper/packaging industry traditionally has a technical product oriented view and product development in the industry is partly made and understood in
This chapter is, in part, about law and legal change. Law – especially intellectual property law – is greatly challenged in a digital society where media is distributed in global networks, for example via BitTorrent sites such as The Pirate Bay. New norms for behavior set up under new pre-conditions in an online environment have emerged alongside the legal, emphasizing some sort of norm-pluralism
Popular Abstract in Swedish Kroppens immunförsvar är vårt skydd mot främmande "inkräktare", såsom virus, bakterier och parasiter. Om dessa mikroorganismer tar sig förbi de fysiska barriärerna, dvs. hud, slemhinnor saliv mm, aktiveras immunsystemet. Immun-försvaret kan delas in i det nedärvda eller naturliga försvaret samt det för-värvade försvaret. Det naturliga försvaret aktiveras först och huvudInterleukin (IL)-1beta is one of the most pleiotropic and potent cytokines, produced predominantly by activated monocytes and macrophages. IL-1 plays an important role in normal immunoregulatory processes but also in pathophysiological inflammatory responses. In the present study, we developed a model for active IL-1beta secretion. A retroviral vector containing a cDNA construct encoding the matur
Popular Abstract in Swedish Den sedimentära lagerföljd som bygger upp Gotland avlagrades för drygt 400 miljoner år sedan (under silurperioden) i ett varmt tropiskt innanhav strax söder om ekvatorn. Innanhavet sträckte sig som en vid bukt in över dagens södra Skandinavien, Baltikum och vidare mot sydost, till Ukraina. Avhandlingen behandlar primärt hur sedimentationsmönster utvecklades under cirka The Silurian foreland of Scandinavia included a vast epicontinental carbonate platform system of which the island of Gotland (Sweden) is an erosional remnant. This thesis treats the Late Wenlock succession (Cyrtograptus lundgreni, Pristiograptus dubius parvus, Gothograptus nassa, Colonograptus(?) praedeubeli, and the Co(?) deubeli zones), and emphasises the sedimentology and biostratigraphy of the
Emission of volatile org. compds. (VOCs) during drying of wood particles for particleboard manuf., or for prodn. of refined biofuels, is a potential environmental problem. The aim of this work is to study the emissions of VOCs during drying, and the influence on the emissions by different drying parameters. The expts. have mainly been done in a batch fluidized bed dryer, but measurements have also
Background: Caldicellulosiruptor species have gained a reputation as being among the best microorganisms to produce hydrogen (H2) due to possession of a combination of appropriate features. However, due to their low volumetric H2 productivities (QH2), Caldicellulosiruptor species cannot be considered for any viable biohydrogen production process yet. In this study, we evaluate biofilm forming pote
Popular Abstract in Swedish Alla levande organismer har DNA, och eftersom DNA är livsnödvändigt måste det repareras om det blir skadat. Ultraviolett (UV) strålning från solen är en av de vanligaste orsakerna till att DNA skadas. De flesta skador på DNA som orsakas av UV-strålning utgörs av cyklobutan-pyrimidindimerer (CPD) eller (6-4)-fotoprodukter. Dessa skador består av två intilliggande baser sAll living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. The major UV-induced DNA lesions are cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts (6-4PPs) and the main repair pathways of theses lesions involve photolyases and various excision repair
The purpose of this research is to achieve a deeper insight of the emulsifying, suspending, and gelling properties of the meat proteins and see the possibility to use them to produce reduced-salt emulsion-type sausages. Sarcoplasmic and myofibrillar proteins were extracted from pork (longissimus dorsi, LD). Firstly, their aggregation behaviors in different salt concentrations – namely, 0.15 M, 0.4
The number of people who choose e-books rather than reading traditional paper books are increasing as a result of our world becoming more digitized. Libraries need to keep up with this trend and modernize its lending procedures for their digital products. The purpose and goal of this Master thesis were to answer the questions how e-books can become more attractive to those who have not yet dared t
Background: The role of physical therapists are affected by several aspects including the therapeutic relationship, inter-professional relations, workloads, autonomy and their relations to everyday tasks. In particular, the latter of these is a topic of interest in regards to Japanese physical therapists since healthcare in Japan has shown tendencies toward the adoption of new technology. This, th
As decarbonization pressures increase for energy-intensive processing industries, understanding demand side readiness is essential in order to scale up breakthrough technologies. This thesis investigates the willingness to pay (WTP) for green steel in the North American automotive industry, with a focus on steel produced by the H2-DRI-EAF route, where hydrogen is produced from renewable electricit
I have always been an avid reader and I have often found myself wondering how other people picture the same spaces that are described. In many cases, the built environment is crucial to build a f ictional world for a story to take place, but sometimes it plays a particularly essential part in understanding the story, its characters and events. In these books, the architecture itself is the story.
