In a previous study, in order to investigate the effect of charge stratification on combustion behavior such as combustion efficiency and combustion phasing which also largely affects the emissions, an experiment was conducted in a heavy-duty compression ignition (CI) metal engine. The engine behavior and emission characteristics were studied in the transition from HCCI mode to PPC mode by varying

Regular midwinter counts of waterfowl (included in theInternational Midwinter Counts, IWC, organized by whatis now Wetlands International) has been undertaken inSweden since the start in 1967 and are still going on,now as a part of the National Environmental MonitoringProgramme. After the first exploratory years includingcountry-wide surveys in 1971–1973 undertaken bothfrom the ground, the air and

Virtual Reality (VR) shooting simulators have gained popularity as effective training and entertainment tools. GAIM is a Swedish company specializing in VR shooting simulators, offering VR headsets with physical dummy guns and rifles. These dummy weapons contain complex electronics that are prone to compilations, especially because the Printed Circuit Board (PCB) is fitted in very compact spaces i

In this paper, we discuss research problems for enabling content distribution and supporting real-time interpersonal communication services (e.g. voice and video) over best effort networks with sufficient quality. We take a practical view of content distribution and quality, and this is the reason for the term “sufficient”. We argue that the understanding of quality as perceived by the user is a k

In this paper we estimate the level and inequality of income for Bechuanaland Protectorate by constructing four social tables between 1936 to 1964 using colonial archives and anthropological records. We present a working hypothesis that there is need to further analyze Botswana’s colonial era if we are to understand several aspects of contemporary economic structures. Our focus is on identifying t

In this paper we present a working hypothesis that there is need to further analyze Botswana’s colonial era if we are to understand several aspects of contemporary economic structures. Our focus is on identifying the roots of post-independence high levels of inequality. We have constructed social tables for 1936-1964, covering all but the very first decades of colonial rule, and based on them we h

Popular Abstract in Swedish Astma och hösnuva (allergisk rinit) är två närbesläktade sjukdomar som båda har sin grund i en långdragen, kronisk inflammation i luftvägsslemhinnan. Vid både astma och hösnuva har slemhinnan en benägenhet att reagera kraftigare än normalt på retningar (s.k. hyperreaktivitet). Inflammationen och hyperreaktiviteten regleras av hundratals olika signalsubstanser (mediatoreMucosal inflammation and airway hyperreactivity are regulated by hundreds of different mediators. The recent discovery of gaseous mediators, produced and active within the airways, opens new possibilities for identification of therapeutic targets and ways to monitor airway inflammation. This thesis is focused on two such mediators, nitric oxide (NO) and carbon monoxide (CO) along with their role i

EasyArchive is a vendor of an email archiving software solution. EasyArchive’s sales are not growing with the same speed as the market, which is forecasted to grow with up to 1000% within the next 5 years. EasyArchive’s direct sales force can expand but the company is also evaluating alternative marketing channels. The number of potential types of channels and the number of players in each channel

Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective. The soot model is then elaborated into mathematical form, starting with the formulation of

We present time-resolved three-dimensional measurements of the averaged liquid mass distribution generated by the Spray M from the Engine Combustion Network. The operating condition corresponds to a non-reacting early injection case for spray-guided gasoline injection during the first 200 μs. Few-femtosecond X-rays from a compact laser wakefield accelerator, enable quantitative spray measurements,

BACKGROUND: Metabolic alterations contribute to disease onset and prognosis of Huntington's disease (HD). Weight loss in the R6/2 mouse model of HD is a consistent feature, with onset in mid-to-late stage of disease.OBJECTIVE: In the present study, we aimed to investigate molecular and functional changes in white adipose tissue (WAT) that occur at weight loss in R6/2 mice. We further elaborated on

In the present thesis, the geographic distribution of variation within such species is investigated and discussed in relation to glacial survival and post-glacial migration, dispersal ability, breeding system and levels of gene-

Syftet med detta examensarbete var att ta fram en enkel och lättförståelig hygienutbildning för nyanställda på Arla i Götene, Västergötland. På detta mejeri tillverkar Arla smör och ost och är även distribution plats för Arlas övriga produkter. När livsmedelverket genomförde en revision av livsmedelsindustrin framkom det avsevärda brister i dokumentation av uppställda rutiner. Även om hygienutbild

I den här uppsatsen diskuteras rättssäkerhetsproblemen med hur informationsutbyte i situationer med dubbel återförsäljning behandlas inom konkurrensrätten i EU. Även frågan om hur sådant informationsutbyte borde behandlas för att öka rättssäkerheten diskuteras. Uppsatsen inleds med en förklaring av rent vertikala och rent horisontella informationsutbyten och hur de bedöms under EU:s konkurrensrät

Coordinated international censuses of the Northwest European Bewick's Swan Cygnus columbianus bewickii population have been undertaken across the swans' wintering range at c. 5-year intervals since 1984. During the early years of the study, numbers increased steadily to a peak of 29,780 individuals in January 1995, but then declined by 39.4% to 18,057 swans counted in January 2010 before showing a

Importance: Coverage of essential child health and nutrition interventions in low- and middle-income countries remains suboptimal. Adverse exposures, such as undernutrition and infections, are particularly harmful during the 1000 days from conception until 2 years of age.Objective: To investigate whether deaths in children younger than 5 years-which also reflect adverse exposures faced by children

Detta projekt syftar till att undersöka om det är möjligt att motivera användandet av teknik för förlängd hållbarhet, ESL, på konsumtionsmjölk genom en minskad miljöpåverkan, speciellt gällande distribution och spill. Trenden pekar idag mot ökande transporter för mejeriernas volymprodukter och dessa transporter jämförs för mjölk behandlad med ESL-teknik och vanlig pastöriserad mjölk. Utöver detta

Purpose: The purpose of this thesis is to examine the impact of diverse boards with one, two, three or more women in limited companies founded in Sweden in 2010 on financial performance. Firm’s characteristics as board’s gender distribution, net sales, ROE, board size and number of employees will be examined aiming to understand how these boards are composed in terms of gender diversity and the im
