Changes in sulphur and nitrogen pollution in Swedish forests have been assessed in relation to European emission reductions, based on measurements in the Swedish Throughfall Monitoring Network. Measurements were analysed over 20 years with a focus on the 12-year period 1996 to 2008. Air concentrations of SO2 and NO2, have decreased. The SO4-deposition has decreased in parallel with the European em
We present experimental measurements of the vibrational relaxation of CO2 (12(0)1) by argon, at ambient temperature (295 +/- 2 K). The CO2 molecules were directly excited to the (12(0)1, J = 14) ro-vibrational state by a tunable laser radiation at similar to 2 mu m. Time-resolved infrared fluorescence technique was used to study the collisional relaxation process. The bimolecular deactivation rate
There is little research on the personalities and emotional stability of persons who report being bullied or witnessing bullying at work. Men and women (N = 247) from 19 to 64 years of age and in manual labour completed a questionnaire concerning the psychosocial work climate, bullying and personality. Three groups were defined: bullied (N = 14), witnesses (N = 31) and non-bullied respondents (N =
Optimisation of cheese yield is crucial for cheese production; a previous study showed large variations in chymosin-induced coagulation in milk from the second most common Swedish dairy breed, Swedish Red. In the present study, the effect of gross composition, protein composition, total and ionic calcium content, phosphorous content and casein micelle size on chymosin-induced gelation was determin
We studied the microbial communities in maize (Zea mays) rhizosphere to determine the extent to which their structure, biomass, activity and growth were influenced by plant genotype (su1 and sh2 genes) and the addition of standard and high doses of different types of fertilizer (inorganic, raw manure and vermicompost). For this purpose, we sampled the rhizosphere of maize plants at harvest, and an
Autoignition of hydrogen in air was studied in a turbulent flow reactor using OH*-chemiluminescence. High-speed imaging was used to visualise the formation of auto-ignition kernels in the flow, and to analyse the conditions under which temporary stabilisation of the flame kernels occurred. The experiments were carried out at temperatures of 800-850 K, pressures of 0.8-1.2 MPa and an equivalence ra
The S 2p core level photoelectron spectra of Sulphurhexafluoride Clusters have been investigated together with heterogeneous Ar/SF6 clusters, created by doping Ar host clusters (with a mean size of 3600 atoms) with the molecule. Surface and bulk features are resolved both in the argon 2p and the sulphur 2p core level photoelectron spectra. For the latter level such features were only observed in t
CaO-based sorbents are considered suitable candidates for cyclic CO2 capture at high temperatures. However, the CO2 capture capacities of natural CaO-based sorbents decrease sharply after only a few cycles. This paper presents a novel wet mixing combustion synthesis to improve the cyclic CO2 capture performance of CaO-based sorbents. Results show that preparation conditions significantly affected
The effects of chocolate shell particle size were investigated by means of its influence on rate of oil migration and fat bloom development. The particle size of the non-fat particles in the chocolate, i.e. sugar and cocoa particles was varied between 15, 22 and 40 mu m. A novel set of analytical techniques was used and by combining migration results with surface topology results clear differences
The pectin content in the soluble and insoluble fractions of fiber suspensions from carrot, potato pulp and apple heat treated in four different ways was determined together with the particle size distribution, water-holding capacity (WHC), morphology and rheological properties of the fiber suspensions. In the carrot and apple suspensions, where beta-elimination was favored, the soluble pectin inc
Process diagnosis is essential to ensure anaerobic fermentation stable and efficient. Here, a novel sensor system combining microbial fuel cell (MFC), gas flow meter and pH meter was developed to evaluate its feasibility for probing the anaerobic process established on a model high-rate bioreactor. Repeated transient responses of electrical signal, proton concentration, and gas flow rate, were obs
Introduction. Radioiodine and most cytostatic treatments are contraindicated in pregnancy. Still, inadvertent therapy does occur. Radioiodine was given to two pregnant women with Graves' disease and thyroid cancer respectively, both in their 20th gestational week. Routine pregnancy tests based on urinary β-hCG had failed to indicate pregnancy in both cases. Methods. Estimation of doses to the foet
Today’s dementia care has demonstrated a widespread use of locking devices in the escape routes of the care units. Most commonly code locks. The locking devices are used to prevent wanderers from wandering away from de dementia unit and risk hurting themselves, disappear or even die. On the contrary, the locks themselves may endanger a safe escape in the case of fire as well as it is may violate t
This research study has sought the contextual understanding of young adults’ realities and the perpetual use of violence within heterosexual intimate partner relationships in Hanuabada village, Papua New Guinea through an interactive transformative approach. Peer interviewers guided the researcher’s tasks and conducted semi-structured interviews utilizing a photo voice methodology to investigate t
In todays knowledge economy the use of information and communcation technology (ICT) is ever increasing. The need for investment in ICT infrastructure is stressed from a range of policy makers. In this thesis, using the concept of virtual proximity, the question of how these ICTs can facilitate innovation for rurally located companies will be discussed. The thesis will be aimed at the plastic indu
Foreign invested SMEs have recently become increasingly interested in China. The enterprises are in this report categorized as second wave companies since they follow the footsteps of previous pioneers, of which mostly were larger companies. The ambitions of the SMEs are either to sell products on the ever expanding Chinese market or to utilize the potential of low cost production for global marke
The report contains an evaluation of the fire safety at Linden shopping centre in Norrköping, Sweden. The evaluation concerns evacuation times, fire development, smoke filling and smoke layer temperatures. The modelling has been executed with the computer models FDS, ARGOS, AST/CFAST and SIMULEX which were validated with hand calculations. The report includes suggestions for improvement of the bui
This thesis discusses two cases of rape against adolescent girls that happened in Cianjur, West Java, and Lombok, West Nusa Tenggara in Indonesia. First of all, the thesis evaluates the availability of the legal framework in the area of rape in Indonesia that ensures the victims rights with regard to rape. It will look at whether Indonesia has ratified relevant international human rights instrumen
This thesis is a critical discourse analysis of ten articles from three Swedish newspapers about the 2011 revolution in Egypt. The purpose of the study is to see if any postcolonial discourses can be found in the reporting and, if so, how we can understand the consequences of these for the way we think about people’s identities and about the future of Egypt. In the thesis’ analysis three postcolo
