Transplantation of embryonic porcine neurons may restore neurological function in patients with Parkinson's disease, if immunological rejection could be prevented. This study was performed to investigate the role of natural killer cells (NK cells) and NK1.1+ T cells (NK T cells) in the rejection of neural xenografts. A cell suspension was prepared from the ventral mesencephalon of 26-27-day-old pi

This paper presents a measurement of the double-differential cross section for the Drell-Yan Z/γ∗ → ℓ+ℓ− and photon-induced γγ → ℓ+ℓ− processes where ℓ is an electron or muon. The measurement is performed for invariant masses of the lepton pairs, mℓℓ, between 116 GeV and 1500 GeV using a sample of 20.3 fb−1 of pp collisions data at centre-of-mass energy of s=8 TeV collected by the ATLAS detector a

Hardwood spent sulphite liquors (HSSLs) are by-products from the pulping industry rich in pentoses, which are not yet fully exploited for bioprocessing, namely for the production of bioethanol. The sustainable fermentation of pentoses into bioethanol is a challenge to overcome. Besides sugars, HSSLs contains inhibitors that decrease the possibility of bioprocessing of these by-products. Neverthele

This paper presents the first attempt to assess the wastewater treatment processes at the oil refinery sector in Kazakhstan and evaluate to what extent these processes follow international and national regulations regarding industrial waste water treatment. The assessment was performed considering wastewater discharge from refining processes at three factories in the country. While Kazakhstani env

This research examines how focus groups can be used as a tool for designing quantitative online surveys suitable for a specific target group. Depending on where in the development process of the survey the researcher is, somewhat different focus groups should be used. If the researcher is far into the development of the survey a focus group with the questionnaire template as discussion basis could

This research tests two different focus groups with the purpose of developing quantitative online surveys suitable for a specific target group. Depending on where in the development process of the survey the researcher is, somewhat different focus groups should be used. If the researcher is far into the development of the survey a focus group with the questionnaire template as discussion basis cou

The purpose of the study is to see if International Accounting Standards for Small and Medium sized entities are suitable for entities in Macedonia, with the emphasis on accounting quality. This thesis has an inductive approach. A qualitative method was selected as a strategy and semi-structured interviews were conducted in order to gather relevant information from the respondent. Hereto, we concl

Koppar-guld fyndigheten Nautanen är belägen 75 km norr om polcirkeln, och 10 km nordost om Gällivare i norra Sverige. Fyndigheten ligger endast 8 km från den stora apatit-järnmalmen i Malmberget och 15 km norr om en av Europas största kopparproducenter, porfyrkoppar-(guld)malmen Aitik. Nautanen beskrivs som en järnoxid-koppar-guld (IOCG) fyndighet eller en hybrid IOCG med en kärna av höghaltiga reThe Nautanen Cu-Au deposit is located 75 km north of the Arctic circle, and 10 km northeast of the town of Gällivare in northern Sweden. Nautanen is just 8 km west of the giant Malmberget apatite-iron ore deposit and 15 km north of one of Europe’s largest copper producers, the Aitik Cu (Au) porphyry deposit. Nautanen is described as an Iron Oxide Copper Gold (IOCG) deposit or hybrid IOCG and conta

This paper deals with how the emerging strand of theorizing – systems of innovation – interprets the determinants of the rate and direction of the innovation process and its implications for policy measures therein. The immense impact technical change has had on economic growth in the past roughly 200 years has demanded an overdue attention since the second half of the twentieth century.And now a

ERP systems have become vital strategic tools in today’s competitive business environment. Achieving successful results from IT initiatives has driven most companies to implement ERP systems in order to achieve strategic alignment between the company’s strategic goals and their business objectives. ERP system implementation involves huge costs, effort, time and resources which if not managed may l

Sammanfattning Det immaterialrättsliga ersättningssystemet är förmodligen mer aktuellt än någonsin. Ett ökat internationellt fokus och de förändringar som bland annat IPRED-direktivet medfört är en del i detta. Dessutom har den tekniska utvecklingen under en period varit stor, sammantaget innebär detta att frågan om ersättning för immaterialrättsintrång är mycket angelägen. Immateriella rättighetSummary The sanctioning of infringements into intellectual properties is a question of severe relevance. Technical development, globalization and legal standpoints such as the Intellectual Property Rights Enforcement Directive has made the topic of this paper a much debated one. The value of intellectual properties can be immense. In fact there are quite a few cases where the most valued assets

Social considerations in public procurement concerns the using of public procurement as a tool in order to achieve political goals of a social nature, such as to reduce unemployment, to ensure a safe and healthy work environment or to combat discrimination. This is potentially a controversial issue since it might come into conflict with public procurement legislation. But the laws concerning this

Samhället genomgick under 1900-talet stora förändringar. Välfärdsstatens socialpolitiska reformer gjorde att familjens roll förändrades – allt fler av de funktioner som tidigare var förbehållna familjen kom nu att övertas av samhället. Kvinnans ekonomiska självständighet och jämställdhet med mannen stärktes. Kvinnor blev också i allt större utsträckning verksamma på arbetsmarknaden. SkilsmässotaleThe society has experienced major changes in the 20th century. The social politics of the Swedish welfare state has impacted the family role. Important functions which were earlier carried out within the family, is now provided by the social welfare system. The economical independency of the spouses and gender equality strengthened during this period. An additional important factor for the reforma

In the past decades, the laser technology market for industrial material processing has grown by double digits. Nowadays, material processing by high power laser represents the almost irreplaceable solution for many needs. The company SEI S.p.A., based in Curno, Italy, requested a solid-state laser suitable for fast marking application. A Nd:YVO4 crystal in end-pumped configuration was chosen in o

Land acquisitions have increased significantly over the last decade and claims have been made that these actions are both neo-colonial and wrong. Others claim that there are benefits to be gained for all parties, directly and indirectly involved. When land is being sold or leased from poor farmers to rich corporations what are the potentials and what are the limitations? Are livelihoods, displacem

This report is made in order to evaluate the safety, in case of a fire, of personnel and patients in the surgical facilities at Helsingborg General Hospital. The problem that arises in this report is regarding the evacuation of patients that are undergoing surgery. This is a problem since it can take up to 60 minutes to finish a surgery and make a patient ready for evacuation. To determine the fir

This thesis offers a study on the performance of the short-term/long-term model by Schwartz and Smith (2000) in the copper futures market for the period 1993-07-21 to 2013-03-05. The model's performance is evaluated in terms of its ability to model the term structure of copper futures prices, and is for this purpose compared to two one-factor benchmark models, an Orstein-Uhlenbeck process and

The redistricting process in the United States of America has been viewed as an unfair, manipulative procedure of drawing redistricting lines to benefit the politicians in power. In an attempt to stop this by creating a more transparent and improved redistricting process, certain states have implemented redistricting commissions for both state legislative and congressional redistricting. This stud
