The soot emissions from diesel engines are much higher in transient operation than during steady state operation. In this thesis, a method for estimating the soot mass flow emission in transient drive cycles is presented. The proposed method uses stationary emission maps in combination with step responses. Bandpass filters are used to filter the engine torque/power to provide transient detection a
Foraminiferer förekommer i marina sediment i världens hav och utgör en värdefull proxymetod för att rekonstruera vattendjup, strömmar, produktivitet och syrenivån vid djuphavsmassor. Valet av storleksfraktion som används när studier på bentiska djuphavs-foraminiferer utförs har visat sig ha betydelse när ekologisk fauna vid upvällningsregioner studeras. En genomgång av tidigare studier har visat aForaminifera are abundant in the marine sediment in all of the worlds’s oceans and offer a valuable proxy method to reconstruct water depth, circulation, productivity and deep water aeration. The choice of size fraction used when studying benthic foraminifera in upwelling areas are important. A review of 15 earlier studies where benthic foraminifera has been analysed, has shown that there are diff
Energy Management needs global attention due to increase in energy demands over last two decades. Commercial buildings and Industrial Facilities are the two most intensive energy consuming sectors that results in high energy expenditure cost and carbon emissions. They have shown interest in energy efficiency and energy management programs to save energy and reduce carbon footprints due to governme
Emotions are influential in determining individuals to donate to charitable causes. However, emotions could interfere with the later decision to whom to allocate the donation resources by making people more likely to donate to a few individual victims instead of many statistical ones. Nevertheless, rationality could direct the allocation decision on the right way (i.e., by donating to statistical
Abstract An ice sheet always experience more or less melting during the summer. How much melting that occurs, is mostly determined by the albedo. Albedo is defined as the amount of the incoming shortwave radiation that gets reflected by a surface. When the sunlight starts melting the ice and snow in the summer, the albedo gets lower. The lower albedo itself causes more absorption of radiation, wh
Storms cause severe damages and cost lives. In order to assess the severity of storms, historical data sets such as reanalysis data can be employed. This kind of data is based on numerical weather prediction models. The realism of model data is limited by the spatial resolution of the model. A numerical weather prediction model is only as precise as its grid distance, meaning that a model cannot d
This thesis considers any existing representations of tragic themes in Plutarch's Lives of Demetrius and Antony. There is a modern debate regarding the nature of the tragic, which is initially adressed. The proposed themes are treated from the perspective of Plutarch's literary and moral intentions, namely the presentation of negative examples.
The present study investigated if the diagnostic value of cues could reduce the need for inhibition operating within the retrieval-practice paradigm, which is part of the retrieval-induced forgetting (RIF). The results of 32 participants (female: 20, age: M = 24.97 years, range: 20 – 32 years) were reported. The method used was a standard RIF procedure with an added manipulation. The category-item
This thesis analyzes Ecuadorian development through a historical perspective, in which the changes related to institutions and beliefs are crucial for the explanation of their dramatic transformation. In this respect, during most of its history Ecuador was characterized for lack of leadership, high external dependence, corruption, selfish interests of groups of power, and huge instability. Indeed,
Popular science summary: Understanding the bacterial cytoskeleton The bacterial cytoskeleton was discovered not too long ago. Since its discovery, it has been a source of information and understanding of how this essential cellular system is established and maintained. The cytoskeleton allows for subcellular organization, which is the key behind many cellular functions. One such function is pola
Secondary organic aerosol (SOA) mass yields were tested for six combinations of two anthropogenic volatile organic compounds (AVOC); m-xylene & toluene, and three biogenic volatile organic compounds (BVOC); α-pinene, myrcene & isoprene. The purpose was to investigate any non-additive results in SOA formation from mixtures of AVOCs and BVOCs by comparing experimental yield with correspondin
Uganda previously had the reputation of being Africa’s food basket, which unfortunately no longer is the case. To mitigate the downwards spiral of soil depletion many organisations, both governmental and non-governmental, introduce land-management systems to farmers, with agroforestry being one example. This study aims to elucidate the importance of the dissemination of information in the context
Title: Pop & rock music students and notation reading from a socio-cultural perspective This thesis is about pop & rock music students and their approach towards notation reading. The examination has been made from a socio-cultural perspective through qualitative interviews with rock music students of various ages and at different educational levels. Central concepts as mediation and disco
Obesity is rising at an alarming rate. The aim of this study was to ask clients in obesity rehabilitation how they experience the role of occupational therapy in the program. A focus group was used and the obesity rehabilitation at Reykjalundur Rehabilitation was chosen as a scene for this study. It is a group program and clients are expected to view their opinions during the diverse sessions of t
Conventional MSWM in the Southern urban cities is gradually moving upward the hierarchy of solid waste management as their disposal capacity diminishes and it becomes dauntingly difficult to locate new disposal site. In Thailand, many municipalities have initiated a source separation scheme as part of their waste management strategy to promote waste reduction. However, the success of the intervent
A brief description of the physical flow phenomena in a blade row that creates losses in an axial gas turbine and correlations to estimate these losses in a mean line calculation are given. Investigation and comparison of the loss correlations for 1D mean line calculation between the in-house program (CTC) used at Siemens and loss correlations present in the open literature were made. The investig
Fertility declines have been taking place across Canada in a number of different provincial family policy contexts since the 1960’s. Although previous studies have assessed the impact of direct cost-reducing family policies in Canada, there is no body of work measuring the impact of indirect cost-reducing family policies across the county. The objective of this paper is to determine whether provin
Decision support systems (DSS) are widely used in both public and private sectors. The objective of our research is to provide knowledge about the actual use and impact of DSS in police organizations. The system that is evaluated in this study is a DSS, recently developed and implemented in the Police organization in Skåne. There is hardly any evaluation done on these systems when used in this par
