Plea bargaining kan beskrivas som att åklagaren, i utbyte mot att den misstänkte erkänner en eller flera gärningar, kan besluta att inte väcka åtal för vissa andra gärningar eller att väcka åtal för ett lindrigare brott. Detta brukar betecknas som åtalsförhandlingar, till skillnad från påföljdsförhandlingar, där åklagaren i utbyte mot att den misstänkte erkänner, går med på en viss straffnivå som Plea bargaining can briefly be described as the possibility for the defendant to confess to one of several charges or to a less serious charge, in return for the prosecution dismissing other charges. This is commonly referred to as charge bargaining unlike sentence bargaining where, in exchange for the defendant confessing, the prosecution agrees to a lenient sentence and requests that it be impos

Aerobic microorganisms have been sources of medicinal agents for several decades and an impressive variety of drugs have been isolated from their cultures, studied and formulated to treat or prevent diseases. On the other hand, anaerobes, which are believed to be the oldest life forms on earth and evolved remarkably diverse physiological functions, have largely been neglected as sources of bioacti

Context. X-ray extragalactic surveys are ideal laboratories for the study of the evolution and clustering of active galactic nuclei (AGN). Usually, a combination of deep and wide surveys is necessary to create a complete picture of the population. Deep X-ray surveys provide the faint population at high redshift, while wide surveys provide the rare bright sources. Nevertheless, very wide area surve

IntroductionThis contribution presents recent research results on segmental andsuprasegmental cues to word-internal and sentence-level structure. InSwedish, prosody is tightly connected to morphological and syntacticstructure. For example, every word stem is pronounced with either a low or ahigh tone. The stem tone depends on what follows the stem. Thus, if asingular suffix is connected to the wor

The ACE-2 HILLCLOUD experiment was carried out on the island of Tenerife in June-July 1997 to investigate the interaction of the boundary layer aerosol with a hill cap cloud forming over a ridge to the north-east of the island. The cloud was used as a natural flow through reactor to investigate the dependence of the cloud microphysics and chemistry on the characteristi

Popular Abstract in Swedish Antagonistiska hot mot godstransporter och logistik såsom stölder, smuggling, förfalskningar och terroristaktiviteter utgör ett stort och ofta förbisett problem. Bara i Sverige beräknas stölder under transport kosta samhället ca 1 miljard kronor årligen. Denna avhandling visar att många svenska transportföretag trots detta inte investerar i lösningar för att förbättra sThe objective of this study is to understand what factors influence the security of physical distribution networks. Thereafter it aims to bring to light what security measures exist today to enhance security and finally how to determine the profitability of security investments.
Eight stakeholders affecting security in physical distribution networks are identified and combined into a Physical

The work presented in this dissertation is concerned with the microstructures and surface roughness of test slabs of Ti-6Al-4V produced by one of powder based Additive Manufacturing (AM) technique namely electron beam melting (EBM). The effects of process parameters of a EBM system and geometry factors of a EBM build such as slabs’ thickness and height etc. on the microstructure and the surface ro

Popular Abstract in Swedish Vid många industriella processer bildas olika typer av biprodukter, som kan vara mer eller mindre giftiga. En ovarsam hantering av de giftiga ämnena, eller en olycka, kan lätt leda till att den omgivande miljön blir förorenad. Förr, när man var mindre medveten om riskerna med de här ämnena hamnade de ofta i marken kring anläggningarna. Det har resulterat i många föroren

Popular Abstract in Swedish Uppskattningsvis 30 % av befolkningen i industrialiserade länder drabbas varje år av förgiftningar och infektioner överförda via livsmedel och frekvensen i utvecklingsländer tros vara högre. För att kunna producera säker mat behövs mer kunskap om vilka egenskaper hos livsmedelsburna patogener, dvs. sjukdomsframkallande mikroorganismer som gör oss sjuka. Dessa egenskaperThe development of new, minimally processed food products challenges traditional concepts of food safety. How pathogenic bacteria behave in these new matrices is not known. To fill this knowledge gap and enable the production of food that is safe for the consumer, more information on virulence expression of pathogens in food matrices is required. In this thesis, the impact of environmental factors

In this report a generic model for the capture and assessment of end-user requirements and needs, the CREDIT carpenter model, has been developed. The main determinants of the model is the need for the project organisation (including the facilities management organisation) to ensure a thorough understanding of the end-user requirements and needs as well as an assessment through out the project proc

Popular Abstract in SwedishMånga skador och olägenheter av fukt kan uppkomma under en byggnads livslängd. De kan t.ex. orsaka hälsoproblem eller dålig ekonomi. För att minska fuktproblem kan en fuktdimensionering göras. I en fuktdimensionering behövs olika fuktberäkningar för att se hur fukttillståndet förväntas bli i eller på en yta av en konstruktion. Beräknade fukttillstånd används för att kont

Do women with Turner karyotype have increased mortality and morbidity in the years after childbirth? No mortality occurred during pregnancy and follow-up in women with Turner karyotype, but a higher rate of circulatory and endocrine diseases and a high risk of aortic aneurysm were confirmed. Pregnancies in women with Turner karyotype are high-risk pregnancies with an increased risk of maternal mor

In a replicated field experiment we studied the effects of natural densities of two exotic consumers, the predatory and herbivorous signal crayfish (Pacifastacus leniusculus) and the predatory rainbow trout (Oncorhynchus mykiss), on multiple trophic levels of a pond community. The goals were to: (1) determine the individual and combined effects of predators on macroinvertebrates, macrophytes, and

Background: Guidelines for the prevention of coronary heart disease call for low-density lipoprotein cholesterol (LDL-C) reduction as the primary target of treatment and reduction of triglycerides (TG) as an additional target. Objective: The purpose of this study was to investigate the ability of atorvastatin and simvastatin to reduce LDL-C and TG concentrations and to meet 3 target lipid levels:

Despite the enormous economic and health-related burdens caused by respiratory infectious diseases globally, there are significant knowledge gaps regarding how these are spread by aerosols. The covid-19 pandemic made it clear that understanding airborne transmission is especially important in healthcare, where workers and patients are highly exposed to sources of virus. This thesis aims to advance
