In this study, we examined the relationship between seed size, seed rain, and seed bank in a species-rich perennial grassland in Sweden. The seed rain was monitored by 100 seed traps placed in a 10 m x 10 m area for 1 year. The seed bank was sampled by taking 100 soil samples, each in close vicinity to a seed trap. Abundance of reproductive ramets in the area was estimated, since this is likely to

A new negligible depletion extraction procedure was proposed for equilibrium sampling of 4-tert-octylphenol (OP) and 4-nonylphenol (NP) into a thin film of 1-octanol supported on a hollow fiber membrane. This thin liquid film extraction technique was directed at the determination of ( 1) freely dissolved concentrations, ( 2) distribution coefficients to 1-octanol (D-ow), and ( 3) binding to dissol

Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. This thesis puts focus on PAR reduction for wireline communication systems, in particular for the mul

A semiconductor (InSb) showed transient metal- like heat conduction after excitation of a dense electron- hole plasma via short and intense light pulses. A related ultrafast strain relaxation was detected using picosecond time-resolved x-ray diffraction. The deduced heat conduction was, by a factor of 30, larger than the lattice contribution. The anomalously high heat conduction can be explained o

We report on an x-ray diffraction (XRD) study of helical poly[9,9-bis(2-ethylhexyl)fluorene] (PF2/6) under high quasihydrostatic pressure and show an effect of pressure on the torsion angle (dihedral angle) between adjunct repeat units and on the hexagonal unit cell. A model for helical backbone conformation is constructed. The theoretical position for the most prominent 00l x-ray reflection is ca

Objectives: To evaluate the use of cellular and cordless telephones as the risk factor For non-Hodgkin's lymphoma (NHL). Methods: Male and female subjects aged 18-74 years living in Sweden were Included during a period from I December 1999 to 30 April 2002. Controls were selected from the national population registry. Exposure to different agents was assessed by questionnalre. Results: In total, 9

As a cost-effective option for Cloud consumers, spot service has been considered to be a significant supplement for building a full-fledged market economy for the Cloud ecosystem. However, unlike the static and straightforward way of trading on-demand and reserved Cloud services, the market-driven regulations of employing spot service could be too complicated for Cloud consumers to comprehensively

Combustion and emissions formation in a Volvo TD 100 series diesel engine running in a homogeneous charge compression ignition (HCCI) mode and fuelled with natural gas is simulated and compared with measurements for both with and without external exhaust gas recirculation (EGR). A new stochastic approach is introduced to model the convective heat transfer, which accounts for fluctuations and fluid

New strategies for prevention and treatment of type 2 diabetes (T2D) require improved insight into disease etiology. We analyzed 386,731 common single-nucleotide polymorphisms (SNPs) in 1464 patients with T2D and 1467 matched controls, each characterized for measures of glucose metabolism, lipids, obesity, and blood pressure. With collaborators (FUSION and WTCCC/UKT2D), we identified and confirmed

In aqueous solutions hydrophobically modified polyethylene glycol (HM-PEG) forms a transient polymer network held together by intermolecular hydrophobic associations. In the present investigation we have used NMR-diffusometry to study how the addition of methylated alpha-cyclodextrin (M-alpha-CD) influences the polymer network. The addit on of M-alpha-CD resulted in an increased mean self-diffusio

Total normothermic venoarterial bypass was established in 6 healthy pigs over a period of 18 hours. A heparin-coated closed extracorporeal system was used and no heparin was administered systemically. During the bypass period the main pulmonary artery was occluded and the heart was maintained in a beating state. All the animals maintained stable hemodynamics and normal blood gases during the entir

The most common noise in geophysical data is probably interference from powerlines. This noise manifests itself as a sinusoidal signal oscillating at the fundamental 50 or 60 Hz frequency of the power grid and as harmonic components oscillating at integer multiples. Many different mitigation strategies, tailored for the specific geophysical method, have been developed to target powerline noise. On

Väpnade konflikter är komplexa och mångfacetterade – män och kvinnors roller och nivå av inblandning varier avsevärt. Med detta i åtanke är det nödvändigt för internationell rätt och dess utövare att erbjuda ett reellt skydd, där ansvarsutkrävande och upprättelse erbjuds på lika villkor för alla oavsett kön. Risken är annars att vissa grupper osynliggörs. Sammanfattningsvis krävs det en nyanserad

Uppsatsen centrerar kring två aktuella frågor: anklagelser om sexuella övergrepp i FN:s fredsbevarande operationer, och konstruerandet av könsroller. De specifika frågeställningarna för uppsatsen är inledningsvis vilka könsroller som konstrueras i primärmaterialet, vilket innefattar tre årliga FN-rapporter. Den andra frågeställningen syftar till att utreda huruvida den konstruerade, militära masku

Sexualbrott är ett ämne upprör och föranleder en ständigt infekterad debatt. Tilltalade personer som frias efter att ha utsatt offer för sexuella övergrepp mot deras vilja har väckt frågan om grunden för våldtäktsbrottet kan utgöras av ett krav på bristande samtycke. Denna uppsats syftar till att undersöka huruvida den svenska våldtäktsbestämmelsen skulle kunna bygga på ett samtyckesrekvisit och dSexual offences bring forth a sensitive and intense debate. Acquittal of offenders guilty of sexually molesting a victim against its will have arisen the question whether the rape crime ought to be constructed with non-consent as a necessary condition. The thesis’ purpose is to investigate whether the Swedish rape crime could be based on non-consent and consequently replace the provision of today,

Japan’s influence in Southeast Asia has been enormous throughout history, whether in its military occupation, culture, or economic ties, and there is no doubt that Southeast Asia has developed under its influence. Have Southeast Asian states then developed and improved their human rights situation because of Japan? Or has Japan aggravated the situation being “blue washed”, by performing its busine

As technology progresses, it seems to become increasingly inevitable for everyday objects in our homes to incorporate advanced features, to increase functionality, convenience, and energy management. This master’s thesis presents the continuation of a Bluetooth lighting system, aiming to develop a comprehensive website solution for handling the provisioning and configuration of Bluetooth Mesh devi

This thesis examines how entrepreneurs organise flexible working practices in self-structured environments and how these shape their perceived work-life balance. Unlike research focused on employees in traditional settings, this study explores entrepreneurs operating with high autonomy and little external structure. Drawing on Self-Determination Theory, Boundary Theory, and Spillover Theory, it in

Entrepreneurship plays an important role in enhancing economic growth, innovation, and social development. Although entrepreneurial success is often linked to individual initiative and risk-taking, knowledge management and networking are recognized as critical components for fostering successful entrepreneurial ventures. The contribution of knowledge hubs in facilitating these elements remains une
