Among the Cyanoprokaryota (blue-green algae), the genus Phormidium has thus far rarely been studied with respect to toxin production and potentially resulting human and environmental health effects. We here show that five previously unexplored freshwater species of this genus (Ph. bijugatum, Ph. molle, Ph. papyraceum, Ph. uncinatum, Ph. autumnale) are indeed capable of producing bioactive compound
The homogeneous charge compression ignition ( HCCI) combustion engine principle lacks direct ignition timing control, instead the auto-ignition depends on the operating condition. Since auto-ignition of a homogeneous mixture is very sensitive to operating conditions, fast combustion phasing control is necessary for reliable operation. For this paper, a six-cylinder heavy-duty HCCI engine was contr
Control beliefs, i.e. a person's perceived control over his or her own behaviour, are important predictors of psychological functioning in old age. The aim of this study is to examine the mediating effect of housing-related control beliefs on the relationship between housing accessibility and independence in activities of daily living (ADL). Moreover, cross-national differences in five European co
Popular Abstract in Swedish Förbränningsmotorer används på flera platser i samhället där energi behöver göras tillgänglig i form av mekaniskt arbete eller elektrisk energi. Den kanske mest kända tillämpningen är som kraftkälla i en personbil. Förbränningsmotorerna har givetvis ett antal fördelar som bidragit till deras popularitet och omfattande användning - lågt pris, kompakthet, driftsäkerhet ocCurrent combustion engines provide excellent performance for vehicle propulsion and power generation. However, recent demands from society ask for higher efficiencies and lower emissions. These requirements are hard to meet with current technology and call for new solutions. Homogeneous Charge Compression Ignition, HCCI, offers a potential to combine high efficiency with very low emissions. It op
Background and AimsApomictic species (with asexual seed production) make up for 20-50 % of all taxonomically recognized species in northern Europe, but the phylogenetic relationships of apomictic species and the mode of evolution and speciation remain largely unknown and their taxonomy is consequently disputed.MethodsIn the present study, plastid psbD-trnT sequences (349 accessions) and 12 nuclear
Microcalcifications are one feature of interest in mammography and breast tomosynthesis (BT). To achieve optimal conditions for detection of microcalcifications in BT imaging, different acquisition geometries should be evaluated. The purpose of this work was to investigate the influence of acquisition schemes with different angular ranges, projection distributions and dose distributions on the vis
This dissertation focuses primarily on the following aspects concerning music in theatre: 1) its experienced peculiarity – ontologically grounded, 2) its sounding scope, and 3) its various kinds of functions. I argue that the difference between spoken theatre and opera is a question of degree rather than essence, and consider such an assertion being especially valid for the music of these genres.
Understanding the mechanisms that govern the combustion processes is important for being able to further increase the efficiency ofcombustion devices. Temperature is considered to be one of the most important parameters controlling the progression and finalproducts of combustion. Regulating the temperature in combustion devices enables higher degrees of efficiency to be achieved. Theengine compone
The aim of this work was to study the effect of time between adrenaline injection and slaughter on the rate and extent of post-mortem metabolism in pig muscle. Five pigs were subcutaneously injected with adrenaline (0·3 mg/kg) or with a saline solution 4 h, 1 h or 15 min prior to slaughter. pH1, pHu and FOPu were measured in Longissimus dorsi (LD) and Biceps femoris (BF) muscles. m.LD samples were
Background: Birds harbour an astonishing diversity of haemosporidian parasites. Renewed interest in avian haemosporidians as a model system has placed a greater emphasis on the development of screening protocols to estimate parasite prevalence and diversity. Prevalence estimates are often based on the molecular or blood-smear microscopy techniques. However, variation in diagnostic sensitivity amon
Abstract The Baltic sub-species of the lesser black-backed gull (Larus fuscus fuscus) occurs within a relatively small region in the Palearctic. It is a monomorphic marine predator that winters in the Mediterranean and Africa. It is listed as ‘near threatened’ in Sweden and the reasons for its decline are not known. The largest breeding colony in Sweden, located on the island of Stora Karlsö, Got
The United States taxes its citizens on their worldwide income. Since the U.S. taxpayers are not always very complaisant the government has had to create ways to disclose and control transactions and penalise non-compliant taxpayers. The United States has been, and is one of the world's leading countries in the fight against harmful tax competition, ever since it decided to implement the Contr
The purpose of this thesis was to study how well the MRD-model (Mould Resistance Design) co-using the hygrothermal calculation software WUFI Pro 6 can predict mould growth in roof structures within long periods of time. The study was done on eleven roof structures situated at Malmberget within Gällivare Municipality between the years of 1961 – 2012 in WUFI Pro 6 (the structures were built around 1
Mn5Ge3(001) thin films grown on Ge(111)-c(2 x 8) reconstructed surfaces were studied by angle-resolved photoemission using synchrotron radiation in the 14-94 eV photon energy range. The results obtained in the Gamma ALM plane and in the Gamma AHK plane are in agreement with simulations starting with band structure calculations based on the density functional theory. This provides a unique validati
Thin films of (B4C)-B-10 have shown to be very suitable as neutron-converting material in the next generation of neutron detectors, replacing the previous predominantly used He-3. In this contribution we show under realistic conditions that (B4C)-B-10 films are not damaged by the neutron irradiation and interactions, which they will be exposed to under many years in a neutron detector. 1 mu m thic
In this study, Dissolved Organic Matter (DOM) quality was analysed through its optical properties. Samples from the estuarine waters of the Beagle Channel and oceanic ones of the Burdwood Bank were examined in order to understand how DOM quality was changing. The focus of the study was to determine whether the environmental variables or the microbial community were the main driver in DOM compositi
När domstolar beslutar om vilket straff en gärningsman ska få för ett visst brott måste de först bedöma brottets straffvärde. En grundläggande ideologi i det svenska straffsystemet är att straffet ska stå i proportion till brottets svårighetsgrad. Vid beaktandet av straffvärdet ska rättstillämparna enligt 29 kap. 1 § BrB bland annat ta hänsyn till den skada, kränkning eller fara som gärningen inneWhen a court decides on what punishment an offender should acquire for a certain crime they must first assess the penal value of the crime. In Swedish penal law a basic ideology is that the punishment should be proportionate to the penal value of the crime. While assessing the penal value the court must consider the damage, wrong or danger occasioned by the criminal act. Through case law regarding
