Earth in 12 hours (the clock) EARTH IN 12 HOURS (THE CLOCK) Earth in 12 hours places our planet’s long history in perspective: if 4.5 million years of geological and biological development were condensed into 12 hours, for how long would there have been life on the planet? When did the moon form? Has there always been oxygen in the atmosphere, or where does it come from? And exactly how long have

Huntington’s disease (HD) is caused by a CAG trinucleotide repeat expansion in the huntingtin (HTT) gene. HD is an inherited progressive neurodegenerative disorder manifested by the wide array of motor dysfunctions, as well as non-motor symptoms. The latter include metabolic dysfunction and psychiatric deficits, such as depression and anxiety, are often observed in patients andanimal models of HD
Biogenic volatile organic compounds (BVOCs) play an important role in the chemistry of the troposphere, especially in the formation of tropospheric ozone (O3) and secondary organic aerosols (SOA). Ecosystems produce and emit a large number of BVOCs. It is estimated on a global scale that approximately 90% of annual BVOC emissions are from terrestrial sources. In this study, measurements of BVOCs w

Popular Abstract in SwedishDenna arkeologiska studie syftar till att förstå de neolitiska samhällenas framväxt, organisation och förändring kring de västskånska ådalgångarna vid Saxån-Välabäcken och Lödde å-Kävlingeån. Arkeologiska undersökningar och fornminnesinventeringen har visat att området hyser omfattande lämningar av neolitiska bebyggelsekomplex — i form av bosättningar, gravfält, megalitgThis dissertation deals with Early and Middle Neolithic societies in a valley landscape in western Scania, in the southern part of Sweden. Several archaeological excavations conducted by the National Heritage Board have revealed a great number of Neolithic remains in this region. The sites constitute a substantial continuous sequence from the earliest to the latest phase of the Funnel Beaker Cultu
Svensk sammanfattningKraftiga förluster av pollinerare är oroande och det har talats om risken för att en pollineringskris ska uppstå, med konsekvenser för både människor och miljö. De flesta blommande växter och tre av fyra odlade grödor är nämligen insektspollinerade (Box 1). Minskningarna hänger ihop med det moderna jordbrukets utveckling. Många gamla hagmarker och ängsmarker där bin och fjärilAgricultural intensification and associated loss of semi-natural grasslands, has resulted in reduced landscape heterogeneity. A concomitant loss of forage and nest sites for pollinating insects has driven declines across several pollinator taxa. Because 75% of the cultivated crops and more than 85% of the flowering plant species are insectpollinated, concerns have been raised that the pollinator d
Svensk sammanfattningAvhandlingens syfte har varit att studera utvecklingen av en könskromosom i realtid genom att simulera dess framväxt i en hermafroditisk plattmask i laboratoriet. Jag gjorde detta genom att selektera på dels honlig fitness (fitness via ägg), dels hanlig fitness (fitness via spermier) med hjälp av en genetisk markör, som agerade som en könsbestämmande gen. Detta ska efterlikna Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. Sexually antagonistic alleles are a type of genetic variation that increases fitness for one sex while being detrimental for the other sex. Recombination arrest around the SDR and gen
The whole society is digitalizing, filled with streaming services, cloud computing and an ambition of ubiquitous connectivity. To address the data demand, ultra-fast broadband, at the speeds of 1Gbps and more, is developed and deployed. Optical fibers have been long viewed as a future-proof carrier for the ultra-fast broadband. However, the physical deployment of fiber networks, including digging,
AbstractParkinson's disease (PD) is one of the most common neurodegenerative diseases in humans. It is a slowly progressing neurological disorder exhibiting major symptoms including resting tremor, rigidity, bradykinesia and postural instability. PD also gives rise to non-motor symptoms such as loss of olfaction, gastrointestinal system disruption, cognitive functional decline, etc. The loss of do
The eating quality of M. longissimus dorsi (LD) from RN- homozygotes, RN- heterozygotes and RN- non-carriers was investigated in a Swedish Hampshire x Finnish Landrace pig population. The recently identified new allele (V1991, here denoted rn*) at the RN locus was also detected among the pigs selected and included in the sensory evaluation. The number of animals varied from 10 to 15 in the five ge
This work aims to study the flow of non-Newtonian fluids and has two main goals. First, the power-law and Herschel Bulkley fluids are studied in a Couette rheometer. Second, the static and dynamic interaction of dual particles in power-law fluid are investigated.For the first goal, Computational Fluid Dynamics (CFD) is employed to understand the flow behavior of powe-rlaw fluid in the Couette rhe

Popular Abstract in Swedish Förmaksflimmer är den vanligaste rytmrubbningen i hjärtat som kräver behandling. Risken att drabbas ökar med åldern och 8% av alla åttioåringar lider av förmaksflimmer. Förmaksflimmer är i sig inte livshotande, men den förhöjda risken för proppbildning i förmaken kan leda till allvarliga komplikationer såsom stroke. Det finns olika behandlingsstrategier för förmaksflimmThis thesis deals with signal processing algorithms for analysis of the electrocardiogram (ECG) during atrial fibrillation (AF). Such analysis can be used for diagnosing patients, and for monitoring and predicting their response to various treatment. The thesis comprises an introduction and five papers describing methods for ECG-based modeling and characterization of AF. Paper I--IV deal with meth
It is generally maintained that learning should be a part of the daily routines of many organizations; this is often referred to as lesson learned processes. The purpose of organizational learning is to foster improvements that seek to both reduce incidents and accidents and reduce their consequences when they nevertheless happen. Safety work is widespread among many organizations, e.g. aviation,

Samtidigt innebär ändrade arbetsformer efter covid-19-pandemin att arbetsgivares behov av sådan kontroll har ökat. Uppsatsens syfte är därför att undersöka privata ar
Bark beetle attacks have led to widespread tree disturbance and deaths in many parts of the world, and thereby also economic and biodiversity losses. Forest-rich Sweden has experienced periodic attacks, latest in 2018. There is a great interest in identifying the most important explanatory features behind bark beetle attacks and making spatial predictions on where attacks might happen. This could
In recent years, there has been a surge in attention towards biodegradable polymer films, driven by the growing environmental awareness concerning the harmful effects of petroleumbased plastics. The maize protein zein, a by-product from wet milling processes, has shown potential to work as hydrophobic coating. The aim of this study has therefore been to find the most promising process conditions f
The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. Human activities' continuous greenhouse gas emission has contributed to global climate change, which has caused some atmos
