Atmosfäriska partiklar (aerosoler) finns överallt i jordens atmosfär. Masskoncentrationen av dessa varierar kraftigt beroende på i vilken miljö man mäter. I stadsluft kan man uppmäta tiotals mikrogram per kubikmeter medan man i arktiska områden uppmäter nanogram per kubikmeter. Den kolhaltiga aerosolen utgör en betydande del av atmosfärsaerosolens massa och är känd för att påverka människors och dCarbonaceous aerosols are known to affect human health negatively and to affect the climate of Earth. As specific types of aerosols originate from specific sources, it is important to know the amount of aerosols emitted from each source. Aerosol source apportionment is an important tool in mitigating air pollution and improving air quality. The subject of this thesis was the evaluation and develop

Predation is a strong selective force in most natural systems, potentially fueling evolutionary changes in prey morphology, life history and behaviour. Recent work has suggested that contrasting predation pressures may lead to population differentiation in personality traits. However, there are indications that these personality traits also differ between sexes and not necessarily in a consistent

Abstract in UndeterminedAgeism has been described as different from other forms of discrimination and paradoxical in the sense that "nonold" people discriminate against their "future selves." The argument of this article is that nonold people may uphold ideas about older people as "the other" by constructing their own future selves as "essentially different" from that of older people of the presen

Paja Brava is a native South American grass with a high carbohydrate content. In the current work, the potential of us- ing this feedstock for ethanol production using a simultaneous saccharification and fermentation (SSF) process with the xylose-fermenting yeast Pichia stipitis (Scheffersomyces stipitis) CBS6054 was investigated. The straw material was subjected to SO2 catalyzed steam pretreatmen

The time evolution of the out-of-equilibrium Mott insulator is investigated numerically through calculations of space-time-resolved density and entropy profiles resulting from the release of a gas of ultracold fermionic atoms from an optical trap. For adiabatic, moderate and sudden switching-off of the trapping potential, the out-of-equilibrium dynamics of the Mott insulator is found to differ pro

The source contributions to carbonaceous PM2.5 aerosol were investigated at a European background site at the edge of the Po Valley, in Northern Italy, during the period January-December 2007. Carbonaceous aerosol was described as the sum of 8 source components: primary (1) and secondary (2) biomass burning organic carbon, biomass burning elemental carbon (3), primary (4) and secondary (5) fossil

In initiating the development of a large-scale golf resort in Aberdeenshire, Trump International Golf Links Scotland made a relatively unknown site central to Scottish planning debates. A stretch of land along the North Sea coast north of Aberdeen became linked to new possible futures. Part of the site developed consisted of moving sand dunes given environmental protection as a Site of Special Sci

This article explores the core propositions articulated by several public actors in the so-called Bandera debate, i.e., discussions about the usable past and legacy of the wartime Ukrainian nationalist insurgency and its central symbolic figure, Stepan Bandera. In Western Ukraine, popular historical imagery as well as intellectual polemics about “Ukrainization” of World War II challenged both the

To evaluate vibrotactile perception at different frequencies in fingers and in foot in healthy girls and boys.

In order to compare the two species’ flight performance over the exposed and windy Falsterbo Peninsula, where thermal conditions seldomly are very favorable, we used tracking radar to study flight parameters of sparrowhawks Accipiter nisus and common buzzards Buteo buteo during autumn migration. The results showed a clear difference between sparrowhawks and common buzzards in their flight altitude

Resonant optical pumping across the band gap was used as artificial doping in InAs/In0.15Ga0.85As/GaAs quantum dots-in-a-well infrared photodetectors. Through efficient filling of the quantum dot energy levels by simultaneous optical pumping into the ground states and the excited states of the quantum dots, the response was increased by a factor of 10. Low temperature photocurrent peaks observed a

The feasibility of measuring g-factors using the TDPAD method applied to high-energy, heavy fragmentation products is explored. The 2623 keV I-pi = 12(+) isomer in Pb-192 with tau = 1.57 mu s has been produced using the fragmentation of a 1 A GeV U-238 beam. The results presented demonstrate for the first time that such heavy nuclei produced in a fragmentation reaction with a relativistic beam are

Holma and Kroksbäck are two socially vulnerable, enclosed neighbourhoods in Malmö, a city in the south of Sweden. There is a development plan to integrate and strengthen these areas. The aim of this thesis was to analyse matters of spatial segregation in an urban development project. How these matters were addressed and what factors might have an impact on them are questions this paper try to answ

Art. 36 TFEU is an exception clause which provides that quantitative restrictions or measures having equivalent effect to quantitative restrictions falling under Art. 34 and 35 TFEU may be justified under certain circumstances. If a national measure can be considered liable to hindering the trade between Member States, the national measure can be justified by one of the derogations listed in Art.

Present uncertainties in key ventilation parameters, characterising the fire performance of facades, has necessitated clarification in the foundational understanding of the Fire Science Body of Knowledge. A test program conducted in collaboration between Lunds Universitet and the Kingspan Group, studied the influence of cavity widths and lateral ventilation conditions on the fire behaviour within

Thessaloniki is a city with a very rich and multicultural history. Among the different groups of people living in the city for centuries, the largest one was the group of the Sephardi Jews. Unfortunately, in modern Thessaloniki the rich Jewish past is not that evident. Aim of this thesis is to search for imprints and memories of the Jewish past in today's city and tries to unfold the reasons w
