Mobility particle size spectrometers often referred to as DMPS (Differential Mobility Particle Sizers) or SMPS (Scanning Mobility Particle Sizers) have found a wide range of applications in atmospheric aerosol research. However, comparability of measurements conducted world-wide is hampered by lack of generally accepted technical standards and guidelines with respect to the instrumental set-up, me

The understanding of biochemical feedback mechanisms in the climate system is lacking knowledge in relation to bi-directional ammonia (NH3) exchange between natural ecosystems and the atmosphere. We therefore study the atmospheric NH3 fluxes during a 25-day period during autumn 2010 (21 October to 15 November) for the Danish beech forest Lille Bogeskov to address the hypothesis that NH3 emissions

This CREDIT Report 3 'CREDIT Performance Indicator Framework' presents a framework of building costs, performance and impact indicators. The framework is an endeavor to map and communicate many and differing approaches and perspectives on building and real estate in one model. The general and specific objectives of the research on the performance indicator framework were to: – Improve transparent

Popular science summary: How do bacteria divide? Cell division is an absolute requirement for proliferation of all bacteria and results in the bacterium being split into two by a septum. FtsZ is a protein that plays a key role in bacterial cell division. In this project, one part of the FtsZ protein was investigated with genetic methods to understand how it affects the division process. Previou

Sverige är ett tämligen unikt land när det kommer till den offentliga förvaltningen. Regeringens underlydande myndigheter har lydnadsplikt, samtidigt som myndigheterna ska vara självständiga. Sverige har inget ministerstyre, utan det är regeringen som kollektivt kan ge direktiv till sina myndigheter. Uppsatsen ämne berör i vilken mån regeringen kan använda sig av så kallade informella kontakter, ”Sweden is a rather unique country when it comes to public administration. The government agencies must show obedience towards the government, but the government agencies are at the same time independent from the government. Sweden does not allow ministerial rule, instead the governmet is forced to give directives collectively. The main subject of the essay is to ascertain in what way the governmen

Unmanned Aerial Vehicles (UAVs) provide a flexible method for acquiring high-resolution imagery with relative simple operation and cost-effectiveness. This technology emerged 30 years ago and it is widely used by commercial, scientific, and military communities due to its versatility. However, new technology brings new challenges. One of them is the radiometric accuracy of the UAV imagery. Radiome

Purpose The purpose of the study has been to estimate the size of the market segment, identify strategically important customers and interesting parts of the segment as well as create an understanding of customer needs when buying furniture for their businesses where care and healthcare is practised. Method The study has been of an exploratory nature with a case study approach since the purpose of

Popular science summary: Having problems with statistics? Try Bayesian! While many of us are afraid of the abstruse concepts and annoyed by a lot of limitations in classical statistics, Bayesian methods provides user-friendly way to do statistics. They are intuitive, explicit and have a wide range of applications. In conservation planning, different sources of evidence need to be integrated to

Popular science summary Do metformin and phenformin cause toxicity to mitochondria of human blood cells? Metformin and phenformin are anti-diabetic drugs associated with lactic acidosis as a rare side effect. This side effect is thought to be due to drug-induced mitochondrial dysfunction. In this project, the mitochondrial toxicity of metformin and phenformin was assessed in human blood cells. I

Seminar date: 30 May 2013 Course: BUSN69 – Degree Project in Accounting and Auditing Authors: Alex Trung Huỳnh and Thảo Trần Supervisors: Anne Loft and Maria Bengtsson Key words: accounting education, university, Vietnam, employability, legitimacy, stakeholders. Background and problem: Since Đổi Mới, the Economic Reformation, in 1986, Vietnam has seen a huge improvement in terms of economic d

Can mussel shells cure heavy metal polluted soils? Heavy metal contamination in soils has become a global concern, as it has recently been increasing due to anthropogenic factors, such as agricultural and mining activities. These practices have led to elevated and unsustainable metal concentrations in soils, causing toxicity and fatality to plants and other living organisms. Heavy metal polluted

Findus Sverige AB, referred to as Findus from now on, harvests peas during a period ofaround 50 days during the summer. The harvest generates about 30 000 tonnes of peas which gives around 40 000 pallets to distribute to the warehouses which Findus uses for final storage. Three hours after the peas are picked in the fields, they have to be frozen to keep their good taste and quality. Because of t

Quantitative reconstructions of past land cover are necessary to determine the processes involved in climate-human-land-cover interactions. We present the first temporally continuous and most spatially extensive pollen-based land-cover reconstruction for Europe over the Holocene (last 11g€¯700g€¯calg€¯yrg€¯BP). We describe how vegetation cover has been quantified from pollen records at a 11 spatia

The members of the genus Caldicellulosiruptor have the potential for future integration into a biorefinery system due to their capacity to generate hydrogen close to the theoretical limit of 4 mol H2/mol hexose, use a wide range of sugars and can grow on numerous lignocellulose hydrolysates. However, members of this genus are unable to survive in high sugar concentrations, limiting their ability t

BACKGROUND: Heart failure (HF) is a progressive disorder characterized by reduced cardiac output and increased peripheral resistance, ultimately leading to tissue perfusion deficits and devastating consequences for several organs including the brain. We previously described a tumor necrosis factor-α (TNF-α)-dependent enhancement of posterior cerebral artery tone and concomitant reduced cerebral bl

Amylin, also named islet amyloid polypeptide (IAPP), is a protein that is processed and released from pancreatic beta-cells in parallel with insulin. Islet amyloid polypeptide is currently studied with regard to a role for insulin resistance in non-insulin-dependent diabetes. To elucidate a possible function of IAPP for impaired glucose tolerance in primary hyperparathyroidism (pHPT), we studied p

The aim of this thesis was to study competitive adsorption of milk proteins during spray-drying. For this purpose, a new surface sensitive method was developed which measures the quantitative amount of specific proteins at the powder surface. The new method is based on steady-state fluorescence measurement of pyrene labelled proteins with oxygen gas phase quenching at the powder surface. The milk

Background: Dietary risks today constitute the largest proportion of disability-adjusted life years (DALYs) globally and in Sweden. An increasing number of people today consume highly processed foods high in saturated fat, refined sugar and salt and low in dietary fiber, vitamins and minerals. It is important that dietary trends over time are monitored to predict changes in disease risk. Methods:

Background: Postural Orthostatic Tachycardia Syndrome (POTS) is a cardiovascular dysautonomic condition affecting predominantly young women. POTS is defined as the presence of chronic symptoms of orthostatic intolerance associated with an increased heart rate ≥30 bpm, or heart rate exceeding 120 bpm, within 10 minutes of standing or head-up tilt in the absence of orthostatic hypotension. The etio

Popular Abstract in English What is common between the science of physics and global politics? They both define power in terms of energy. Indeed, the uneven distribution of petroleum reserves has been one of the main reasons of social, political and economic problems worldwide. Even more worrying is the rapid increase in the levels of greenhouse gases in the atmosphere. This is mainly caused by ouCaldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. Due to its CO2-free combustion and high energy density, among other desirable properties, H2is touted as a fuel of the future. Biological H2 production b
