Popular Abstract in Swedish I Big Bang, då vårt Universum skapades, bildades i princip endast de två lättaste grundämnena, väte och helium. Alla andra grundämnen har skapats, och skapas fortfarande, i olika typer av stjärnor under olika utvecklingsfaser. Detta betyder att precis alla atomer, förutom väte och helium, som bygger upp alla saker, växter, djur och människor i vår omgivning, har bildatsDisregarding the small primordial traces of the lightest elements, all metals have been formed in stellar processes, which means that the relative amount of metals in the Universe increases for every stellar generation. This build-up of elements is called chemical evolution and might be used both to constrain stellar models as well as understanding the formation and evolution of stellar population

This thesis is based on work done 1991-1996 using the DELPHI detector at LEP, and is summarized in four articles. It consists of four main parts. The first part describes the Very Small Angle Tagger (VSAT) and Small angle TIle Calorimeter (STIC), which are sub-detectors of DELPHI. The VSAT consists of four silicon-tungsten electromagnetic calorimeter modules, having silicon strip planes for accur

Popular Abstract in Swedish Med syftet att utvärdera tillämpbarheten av den ytvågsseismiska tekniken Spectral Analysis of Surface Waves (SASW), vilken används för bestämning av skjuvmodulen (Gmax), har fyra olika tillämpningsområden studerats. De fyra områdena har varit lokaler med naturliga jordförhållanden, lokaler där enbart icke-förstörande metoder normalt är möjliga att använda, test av vägbaWith the main aim to test the applicability of the surface wave seismic technique Spectral Analysis of Surface Waves (SASW), used for determination of the shear stiffness (shear modulus - Gmax), four areas of applications have been studied. The four areas have been sites with natural geological conditions, sites where non destructive testing is necessary, pavement testing and multichannel testing.

Background The Ho: YAG laser is used extensively in orthopedic surgery. It offers a minimally invasive method of ablating tissue with precision. Previous studies have explored the effects of laser use on temperature during experimental foraminoplasty. To date, there has been limited work on the effects of thermal stress on cells in this context. Material and methods Cells were exposed either to h

"Troublesome People" is a book on the Swedish feminist theater director Suzanne Osten.

As average packet sizes in wireless networks shrink and data rates increase, the fundamental CSMA mechanism in the 802.11 protocol family is put under stress. With the emerg- ing 802.11ax standard, the carrier sensing mechanism is low- ering the efficiency of the protocol to the level of random access (ALOHA), and as future-generation 802.11 standards emerge, CSMA-based protocols will fall below t

Popular Abstract in Swedish Ledgångsreumatism (reumatoid artrit) är en allvarlig inflammatorisk led- och systemsjukdom som drabbar ungefär 1% av befolkningen. Den är sannolikt den vanligaste behandlingsbara orsaken till invaliditet i västerlandet. Under de senaste 10 åren har allt fler forskare uppmärksammat sjukdomens dåliga prognos och manat till en tidigare och mera effektiv behandling så snartRheumatoid arthritis (RA) is probably the most common source of treatable disability in the Western world. There are several disease-modifying antirheumatic drugs (DMARDs), which have proven to be of therapeutic efficacy in RA, but the lack of a potent, reliable treatment for early RA is a major problem in modern medicine. An obvious line of approach in the quest for better antirheumatic drugs is

This paper attempts to address the failings of a predominant paradigm in IS research and practice that emphasises technological determinism. This paradigm makes use of a false belief in the power of rationality in organizational decision-making, and a mythology in which organizational actors can be viewed as passive ‘users’ of technology. We wish to create a discussion of the nature and role of pr

The optical design for the proposed Euro50 extremely large telescopewith integrated adaptive optics (AO) is presented. For atmosphericturbulence correction, we propose using single and dual-conjugate AOsystems working with natural and laser guide stars. The corrective shapeof the deformable mirrors (DMs) is derived from an analytical algorithmbased on minimization of the sum of the residual power

While contemporary international law is often understood as teleological, encompassing notions such as progress, development, and prosperity for all of human kind, in this essay the field of the international law of belligerent occupation is read as katechonic, as embodying the figure of the katechon within international law’s eschatology. The essay considers Carl Schmitt’s political theology thro
