The last decades have seen a renewed interest in the study of argumentation in archaeology, particularly in response to the overproduction of weak and unreliable interpretations and explanations. Concurrently, recent appeals for scientific transparency and efficiency in the management of archaeological information in digital form have stressed the necessity of explicitly showing the processes foll

An investigation of the autonomy of the process region at the tip of a crack is carried out. An elastic plastic linearly hardening material is assumed. A cohesive zone model with constant cohesive stress is chosen. The cohesive zone length is observed to decrease with decreasing hardening rates and increasing cohesive stresses. For a cohesive stress larger than about three times the yield stress t
The rate constants for the chloride and bromide anations of Pd(H2O)42+, the chloride anations of PdCl3H2O−, the bromide anation of PdBr3H2O− and the acid hydrolysis of PdCl(H2O)3+, PdBr(H2O)3+, PdCl42−, and PdBr42− have been determined at 15, 25 and 35 °C using a stopped-flow technique. The ionic strength was 1.00 M and the supporting electrolyte perchloric acid.

The exploitation of migrant workers is widespread in the Nordic countries in labour intensive sectors. This article investigates whether there is any criminal law protection in practice for exploited migrant workers in Sweden. On the basis of descriptive statistics regarding the outcomes of criminal investigations on human trafficking for forced labour and on human exploitation for forced labour a
Uppsatsens huvudsyfte har varit att utröna om det fanns några skillnader ipolitisk kultur mellan de socknar som låg i Blekinge och de socknar som låg ide gammalsvenska delarna av Sverige. Frågan tar sin utgångspunkt i K.H. Johanssons klassiska avhandling om de svenska sockenstämmorna. Han drar slutsatsen att stämmorna var demokratiska institutioner, där alla församlingens medlemmar fick delta och The main aim of this study was to determine whether there were any differences in political culture between the parishes of Blekinge and parishes in the older parts of Sweden. The question has its point of departure in K. H. Johansson's now classic dissertation on the Swedish parish assernbles. He reaches the conclusion that the assemblies were democratic institutions, in which all the members of
We provide a detailed account of the origin and establishment of the Osteoarthritis Research Society International (OARSI) and celebrate its history from inception to the current day. We discuss the mission, vision and strategic objectives of OARSI and how these have developed and evolved over the last 3 decades. We celebrate the achievements of the society as we approach its 30th birthday, honor
The JUNGFRAU 4-megapixel (4M) charge-integrating pixel-array detector, when operated at a full 2 kHz frame rate, streams data at a rate of 17 GB s-1. To operate this detector for macromolecular crystallography beamlines, a data-acquisition system called Jungfraujoch was developed. The system, running on a single server with field-programmable gate arrays and general-purpose graphics processing uni
Massive multiple-input multiple-output (MIMO) is expected to be a vital component in future 5G systems. As such, there is a need for new modeling in order to investigate the performance of massive MIMO not only at the physical layer but also higher up the networking stack. In this paper, we present general optimization models for massive MIMO, based on mixed-integer programming and compatible sets
Att silver har en bakteriedödande effekt har varit känt sedan många århundraden. Historien om silver sträcker sig ända tillbaka till 4000 år före Kristus då de antika Kaldeérna använde silver och det var på den tiden en av mest använda metallerna tillsammans med guld och koppar. Persiska kungar föredrog att dricka vatten endast från bägare gjorda av silver för att vattnet kunde bevaras friskt och Over the past decade, a massive increase in the use of nanomaterials and nanoparticles (NPs) in both commercial and medical applications has occurred. Medical applications include advanced drug delivery vehicles, imaging and hyper thermic therapies. In retinal research, several nanomaterials have been explored in novel treatment approaches, ranging from metals, carbon, polymers and silica to biolo
Framställningen utreder huruvida gällande rätt och rättstillämpning avseende tvångsadoption korresponderar med adoptionsinstitutets ändamål på ett tillfredställande vis. Framställningen avser även klargöra gällande rätt och vilka intressen som påverkat institutets utformning. En förutsättning för adoption är att den är till fördel för barnet. Det innebär att en adoption inte kan ske om den inte tiThis thesis investigates whether the current legislation and the application of the law concerning forced adoptions corresponds with the Swedish adoption institute's aim in a satisfactory manner. The paper also pertains to clarify the current legislation and the interests that have influenced the institute’s design. A prerequisite for adoption is that the child benefits from it. This means tha
For some time now “Rondellen”, a roundabout just outside Folkets Park in Malmö, has been a place where drug transactions are taking place out in the open street. Buyers know that sellers will be there for a quick and easy transaction in a central part of Malmö. But why are the transactions taking place just there? A lot of people are passing by who can watch them trade or the police can come aroun
Sammanfattning Surrogatmoderskap är inte är tillåtet i Sverige och har på senare tid blivit en mycket omdebatterad och högst aktuell fråga. Till följd av förändrade uppfattningar och föreställningar i samhället utreds nu huruvida surrogatmoderskap kan införas som en metod för att avhjälpa ofrivillig barnlöshet. En viktig aspekt på området är att hänsyn måste tas till det blivande barnet. BedömningSummary In Sweden gestational surrogacy is not allowed and has recently become a very controversial and highly topical issue. Due the changing perceptions and beliefs in society, it is now being investigated whether surrogacy can be introduced as a method to overcome involuntary childlessness. An important aspect of consideration must be to the prospective child. In assessing if gestational surrog
Doktrinen om R2P kom som en respons på de omfattande grymheter som skedde runt om i världen på 1990-talet. FN hade inte kunnat agera och förhindra de övergrepp som den civila befolkningen i exempelvis Rwanda och forna Jugoslavien hade blivit utsatta för. Man kom överens om att det krävdes en förändring för att ett skydd av de mänskliga rättigheterna skulle garanteras. Av denna anledning tillsattesThe doctrine R2P came as a response to the mass atrocities around the world during the 1990s. The UN had not been able to act and prevent the atrocities against the civilian population in, for example, Rwanda and former Yugoslavia. This demanded change, and therefore the ICISS Commission was appointed. The ICISS Commission wrote the rapport about “The Responsibility to protect”. According to their
Klimatförändringarna är ett globalt hot mot människors och djurs välbefinnande på jorden. Hotet om klimatförändringar har varit känt i över 30 år och i cirka 10 år har det varit ett faktum att människan är den främsta bidragande faktorn till det. Trots detta är klimatförändringarna år 2022 inte längre ett abstrakt fenomen utan vår verklighet. En av anledningarna till att så lite har gjorts för attClimate change is a global threat to human and animals’ well-being on Earth. The threat of climate change has been known for over 30 years and it is now a fact that humans are the main contributing factor to it. Despite this, in 2022 it is no longer an abstract phenomenon, but our reality. One of the reasons why so little has been done to save the environment is people’s lack of or insufficient kn
