Pair correlations between large transverse momentum neutral pion triggers (p(T) = 4-7 GeV/c) and charged hadron partners (p(T) = 3-7 GeV/c) in central (0%-20%) and midcentral (20%-60%) Au + Au collisions at root s(NN) = 200 GeV are presented as a function of trigger orientation with respect to the reaction plane. The particles are at larger momentum than where jet shape modifications have been obs
Lead was an essential part of bullets used at shooting ranges in Sweden. This has lead to that many shooting ranges have elevated amounts of lead in the soil, ie. lead ground contamination. As lead causes severe health effects on humans and animals, and accumulates in the nature then this is of great concern. This contamination and its effects on humans is also very important since many of those s
Contracts in the EU operate in a complex legal environment. Depending on the situation, they are subject to a patchwork of national, European, and international rules. As a result, economic operators exercising the ‘four freedoms’ find themselves in a great ocean of private international law, containing smaller islands of EU law and national rules. This paper explores some of the fundamental issu
This paper evaluates the impact of state visits on export flows and the specific role of the head of state based on the five Nordic countries: Denmark, Finland, Iceland, Norway, and Sweden. We construct a complete and comprehensive dataset containing all outgoing state visits from the Nordic countries between 1973 and 2022. Our main empirical strategy is to apply a difference-in differences (DiD)
Information and communication technology has emerged significantly over the past two decades. The ever-growing trade and monetization of digital encounters are likely to extend technology even more in the upcoming decades. Recent technological developments have brought various advantages worldwide, such as effective communication, increased production, and artificial intelligence, which can solve
This thesis is devoted to the analysis of the I-V properties of axial InP pn-junction nanowires made for solar cell application. A novel method has been used to measure the I-V characteristics very accurately and reproducibly, using scanning tunneling microscopy (STM). The STM is used to first image the nanowires from top and then form a low resistive point contact between the STM tip and an indiv
The purpose of this report is to investigate the implications of installing sprinkler systems in ceilings with a ceiling slope exceeding the maximum permitted by NFPA 13, being 9.5 ° or 18.44 ° depending on the type of sprinkler system. The objective of the report is to present a comparison and analysis of sprinkler activation times and patterns for sprinkler systems installed in ceilings with dif
A discussion on whether different national interpretations sit comfortably with the rationale for the uniform Court of Justice term "worker" and whether this situation can be justified in the light of the potential unlevelling of the internal market and Article 30 of the Charter of Fundamental Rights
There is a call for more analysis and case knowledge of how the media use the participatory architecture of social media in media production. The research field of audience participation comes from the integration of concepts and theories about an active audience with production research, and social and cultural theory. This thesis analyses cultural participation from the perspective of profession
This paper empirically investigates the relationship between industrial ownership and environmental degradation in the People’s Republic of China, with specific focus on two environmental indicators: volume of SO2 emissions and volume of industrial wastewater deemed unsafe for discharge. Sulfur dioxide and untreated wastewater emissions are considered some of the most problematic environmental and
The enzyme beta-galactosidase was purified from a cold-adapted organism isolated from Antarctica. The organism was identified as a psychrotrophic Pseudoalteromonas sp. The enzyme was purified with high yields by a rapid purification scheme involving extraction in an aqueous two-phase system followed by hydrophobic interaction chromatography and ultrafiltration. The beta-galactosidase was optimally
The effects of two sympathomimetic drugs on mucociliary activity and mucosal blood flow in the rabbit maxillary sinus were investigated by using a photo-electric technique (mucociliary activity) and laser Doppler flowmetry (blood flow). The responses produced were compared with effects of ligation of the external carotid artery. The alpha 1-agonist phenylpropanolamine (0.1-100 micrograms/kg) had n
Antimicrobial resistance patterns and capsular groups of penicillin-resistant Streptococcus pneumoniae (PRP; MIC penicillin G >= 0.5 mg/ml) in Sweden between 1997 and 2003 were described, and trends in resistance and antibiotic sales during the same period were compared. The most common serogroups were in descending order 9, 19, 14, 23, and 6. Despite a low and stable annual PRP rate (proportion o
Prehistorical musical instruments have been explored in archaeology more systematically since the 1970s when music archaeology was established as a field of study. The new awareness initially led to studies centred on retrieving musical instruments that had been missed and were now lost in archives. New discoveries, too, are very object-oriented. This master’s thesis ties together individual finds
Moderate exercise is deemed beneficial for cognition due to increase in dopamine concentrations in the basal ganglia. Auditory white noise is beneficial for cognition, mainly for those with lower attentional ability, i.e. for those having lower tonic dopamine concentrations. For individuals with higher attention ability white noise can have a negative effect. In this thesis it was examined whether
