Around 70,000 osteoporosis-related fractures occur in Sweden annually and approximately half of the women in western world will sustain a fragility fracture after the age of 50 years. Fracture preventive efforts require the identification of individuals who are at high risk. Biochemical markers of bone turnover (BTMs) have shown some degree of fracture predictability. There is also a correlation b

BACKGROUND: Gonadotropin-releasing hormone (GnRH) antagonists have been reported to have beneficial effects on lower urinary tract symptoms in patients with benign prostatic hyperplasia. OBJECTIVE: Our aim was to investigate the effects of ganirelix, a GnRH receptor antagonist, on bladder function and detrusor overactivity (DO) in female rats. DESIGN, SETTING, AND PARTICIPANTS: Female Sprague-Dawl

Med den globala uppvärmningen förutspås klimatet i arktiska och subarktiska miljöer förändras påtagligt. Enligt IPCCs senaste rapport kan både temperatur och nederbörd öka dubbelt så mycket som det globala genomsnittet, och störst ökning väntas under vinterhalvåret. Många känsliga ekosystem och miljöer kommer med stor sannolikhet att påverkas redan vid små förändringar. Ett exempel på sådana miljöThe on-going global warming is projected to have large impacts on the arctic and subarctic environment. Especially vulnerable are ecosystems with narrow climatic envelopes and with small possibilities of adaptation. An example of this is the palsa mires, subarctic mire complexes with patches of permafrost. Palsas are peat mounds with a frozen core, formed by the expansion and upheaval of the segre

Globalization has since the 90s played a big part in the way companies look at their business and strategic developments. Acting on a global scale introduces a new complexity when it comes to running a business successfully. Alfa Laval being a global player within their product segments, experiences this complexity with production facilities as well as employees spread around the globe combined wi

En vegetationskarta och en digital höjdmodell har gjorts över ett 54 km2 stort område beläget på Svalbards västkust, vid Isfjorden. Vegetationskartan är baserad på flygbilder och en undersökning gjord i fält under juli månad 1994. Systemet som användes vid klassificeringen av de olika vegetationstyperna är utarbetad av Elven et al. (1990) för en liknande studie i Gipsdalen på Svalbard. Vår vegetatA vegetation map and a Digital Elevation Model has been generated over a 54 km2 area situated at the western coast of Svalbard, at the Isfjorden fiord. The map is based on aerial photographs and a field survey made during the summer of 1994. The classification system used is described by Elven et alia (1990), for a similar study in Gipsdalen in the inner part of Isfjorden. The classification of th

As the consumption of energy increase in today’s world, the need for new fuel sources is of central importance. In order to be considered viable in the long run, the new energy sources must provide high efficiency and low environmental impact. The search for alternative fuels and energy extraction methods have become increasingly focused on finding ways to mimic systems found within nature. Oxidor

Med ökad andel intermittent elproduktion i Sveriges elproduktionsmix och ett åldrande stamnät ökar behovet av flexibilitet i elsystemet. Lagring av energi, till exempel i vätgas, är ett exempel på en sådan flexibilitetslösning, eftersom energin kan flyttas från tidpunkter med överskott till tidpunkter med högt energibehov. Syftet med examensarbetet är att undersöka energisystemnyttan med ett v ägaSweden’s increasing share of intermittent electricity production and aging backbone network has given rise to a need for flexibility in the energy system. A potential solution to this challenge is energy storage, where hydrogen is a possible pathway. This master’s thesis aims to investigate the energy system benefits of a hydrogen system for seasonal energy storage of excess solar electricity in a

Titel: Validering av en handledsburen aktivitetsmätare och en självskattningskala för beräkning av VO2max. Bakgrund: Fysisk aktivitet och god aerob kapacitet är kopplat till god hälsa och lägre risk för livsstilsrelaterade sjukdomar. I dagsläget anses maximalt arbetsprov med ergospirometri och gasanalys för bestämning av VO2max (VO2max-test) vara det mest exakta sättet att mäta aerob kapacitet. Su

Bakgrund: Obesitas och psykisk ohälsa tillhör de största globala hälsoutmaningarna i modern tid och har under de senaste decennierna varit ett växande problem. Människor har fått en mer stillasittande livsstil och större tillgång på kaloririk föda. Faktorerna som påverkar prevalensen är många men att det behöver ske en förändring är säkert. Syfte och frågeställningar: Syftet var att kartlägga BMI,

People’s ability to learn holds a promise for sustainability as learning is seen to enable change; yet, the prevalence of norms and values in society that reinforce unsustainability may severely challenge this process. The debate on what role learning can play is centered around the question whether people can learn from others and if so, how to enhance it. More precisely, who has to learn what fr

“There is no tool for development more effective than the empowerment of women,” Kofi Annan (UN News Center, 2005). The empowerment of women takes different forms such as pursuit of education, participation in political activities and representation in leadership, equal employment opportunities and wages, access to health care and ability to make decisions on personal reproductive health, economic

Sex chromosome evolution is a fascinating research topic because sex chromosomes provide a snapshot of evolution in many different lineages. Sex chromosomes often cease to recombine and therefore degenerate, and have also often been reshuffled during their evolution from autosomes. It has been discovered that within Sylvioidea passerine species half of chromosome 4a has translocated and fused with

Remote sensed vegetation biophysical indicators are derived from various sensors and methods and contribute to the quantification of vegetation growth. They are used as inputs to early warning systems for crop yield estimation, thus improving crop management and food security. However, the performance of any such system is affected by the performance of the chosen remote sensed biophysical indicat

Denna uppsats undersöker NJA 2023 s. 393 (”Vapenattrappen”), och dess konsekvenser för såväl gällande rätt som domstolarnas rättstillämpning. Domen kom under våren 2023 att kritiseras hårt. I målet stod två män åtalade för försök till vapenbrott, eftersom de påstods ha försökt inneha vapen. Vapnen byttes emellertid ut mot en ofarlig attrapp av polis ca. fyra månader innan de tilltalade dök upp, vaThis paper examines NJA 2023 s. 393 ("The Dummy Weapon"), and its consequences for both current law and practical legal application. The verdict would come to be heavily criticized during the spring of 2023. Two men were prosecuted in the case. They were charged with attempted exceptionally aggravated weapons offence, since they had allegedly tried to possess firearms. The firearms had,

Herpes Simplex Virus type 1 (HSV-1) is a virus infecting over 90 % of the population. It causes latent infections in nerve cells and can upon reactivation travel along the neurons and cause lytic infections with painful blisters as a result. HSV-1 infects multiple cell types, fibroblasts and T-cells among others. During infection HSV-1 is known to downregulate the transcription of many of the gene

The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. The yield was recorded with a new optical sensor, which uses a digital camera to detect objects and records th
