Popular Abstract in Swedish Den nuvarande teknologin inom förbränningsmotorer har möjligheten att hantera den alltmer strikta myndighetskraven på förbränningsmotorn. Emellertid de nödvändiga tekniska lösningarna som krävs är dyra och alltmer tekniskt krävande. En möjlig väg mot enklare efterbehandlingssystem är anvädningen av Homogen Kompressions Antändning (Eng: HCCI) motor cykeln. Den huvudsaklThe current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. One possible way towards a more simple exhaust aftertreatment system is the use of the Homogeneous Charge Compression Ignition (HCCI) engine cycle. The main advantage o

In a previous paper we were able to measure the abundance of uranium andthorium in the very-metal poor halo giant BPS CS31082-001, but only obtained an upper limit for the abundanceof lead (Pb). We have got from ESO 17 h of additional exposure on thisstar in order to secure a detection of the minimum amount of leadexpected to be present in CS 31082-001, the am

To date, it is widely accepted that several disorders of the male and female urogenital tract, such as erectile dysfunction, bladder overactivity, urinary stone disease and the benign prostatic syndrome, can be therapeutically approached by influencing the function of the smooth musculature of the respective organs. In order to achieve a pronounced drug effect without significant adverse events, e

Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. It is thought that VHb facilitates oxygen delivery to the respiratory apparatus of its host by increasing the local oxygen concentration under oxygen-

Popular Abstract in English Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. Chemical analysis of aerosols involves broadly two steps, extraction step and detection/quantification of chemical constituents

The sialyl Lewis x (SLex) tetrasaccharide is the smallest recognizable ligand for selectins. The selectins constitute a vital part of the inflammatory cascade for recruitment of leukocytes to a site of tissue damage or microbial infection. If too many leukocytes are recruited, normal, not injured, cells can be damaged; a process known from chronic inflammatory diseases such as reumatoid arthritis,

The partly hot-water driven CO2 capture plant offers a significant potential for improvement in performance when implemented in a combined-cycle power plant (CCPP). It is possible to achieve the same performance with a dual-pressure steam cycle as in a triple-pressure unit. Even a single-pressure plant can attain an efficiency competitive with that achievable with a triple-pressure plant without t

The European Space Agency's Gaia satellite was launched into orbit around L2 in December 2013 with a payload containing 106 large-format scientific CCDs. The primary goal of the mission is to repeatedly obtain high-precision astrometric and photometric measurements of one thousand million stars over the course of five years. The scientific value of the down-linked data, and the operation of the on

Background We attempt to develop a relatively comprehensive structural model of risk factors for drug abuse (DA) in Swedish men that illustrates developmental and mediational processes. Methods We examined 20 risk factors for DA in 48,369 men undergoing conscription examinations in 1969–70 followed until 2011 when 2.34% (n = 1134) of them had DA ascertained in medical, criminal and pharmacy regist

Having multiple control tasks concurrently running on a single computing platform increases the processor utilization but degrades the control performance due to delay and jitter. In scheduling and control codesign, the objective is to optimize the combined performance of all the controllers, subject to a schedulability constraint. The codesign procedure consists of selecting task parameters, e.g.

In 2010 the Mozilla Foundation established the Digital Open Badges concept as a virtual incarnation of physical counterparts such as a paper certificate or a youth organisation merit badge. Digital Open Badges offer embedded, verifiable, metadata containing information such as the issuer and award criteria. Open Badges can be used to reward learning, participation or achievement. They can be store

This paper considers instantaneous impulses in multibody dynamics. Instantaneous impulses may act on the multibody from its exterior or they may appear in its interior as a consequence of two of its parts interacting by an impact imposed by a unilateral constraint. The theory is based on the Euler laws of instantaneous impulses, which may be seen as a complement to the Euler laws for regular motio

5G NR är den senaste generationen mobilnät och är efterföljaren till Fourth Generation (4G) Long-Term Evolution Advanced (LTE-A). I mobilnäten kan användare koppla upp sig mot basstationer med sina enheter som kan vara en mobiltelefon eller dator. Basstationerna består av antenner som kan både skicka och ta emot information samt en radioenhet som hanterar trafik till och från stationen. Eftersom aAs the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. This thesis investigates how the DSP load in the base station behaves for a

I svensk rätt tillämpas asperationsprincipen vid straffvärdebedömning av flerfaldig brottslighet. Vid flerfaldig brottslighet ska ett gemensamt straffvärde bestämmas och domstolen utgår från det allvarligaste brottets straffvärde och de övriga gärningarnas straffvärden reduceras i en fallande skala. Detta system har mött kritik i form av att påföljderna vid flerfaldig brottslighet blir för milda iIn Swedish law, the principle of asperation is applied when estimating the penal value for multiple offences. In the case of multiple offences, a common penal value is determined and the court starts from the most serious offence, with the penal value of the other offences being reduced on a descending scale. This system has been criticized for making penalties for multiple offences too lenient in

Objective: The aims were to evaluate the frequency and nature of errors in medication when patients are transferred between primary and secondary care. Method: Elderly primary health care patients (> 65 years) living in nursing homes or in their own homes with care provided by the community nursing system, had been admitted to one of two hospitals in southern Sweden, one university hospital and on

Frequent land-use changes in urban areas require an efficient and dynamic approach to reform and update detailed plans by re-arrangement of surrounding land-uses in case of change in one or several urban land-uses. However, re-arrangement of land-uses is problematic, since a variety of conflicting criteria must be considered and satisfied. This paper proposes and examines a two-step approach to re
