We review some new literature on diatoms, with emphasis on genomics, evolution, ecology and biomimetic nanotechnical applications. Diatoms account for a substantial part of the photosynthetic production on this planet, and their genome is a mosaic of contributions from different sources. They occupy very diverse ecological niches, and may have been the first organisms to carry out C4 photosynthesi
Popular Abstract in Swedish Sammanfattning på svenska Den svenska nationella cancerstategin från 2009 understryker patientperspektivet och fokus ligger på själva patientprocessen. Modern bröstcancerbehandling omfattar en mer individualiserad behandling med bröstbevarande kirurgi, diagnostik av portvaktskörteln, ett ökat användande av medicinsk terapi med cellgift, antihormon samt antikroppar i såAbstract Background. The Swedish national cancer strategy programme published in 2009 emphasises the patient perspective and focuses on the patient process. Over the years the different modalities in breast cancer treatment are changing position, making accurate diagnosis and quality assurance in breast pathology even more important than before. Aims. The aim of paper I was to examine overall su
Four fire extinguishing agents has been investigated, bromotrifluoromethane, Halon 1301, pentafluoroethane, HFC 125, heptafluoropropane, HFC 227ea and dodecafluoro-2- methylpentane-3-one, C6F-ketone. The inerting concentrations were determined in a cubic pressure vessel with a volume of 8 litres. A cup burner was used to find the flameextinguishing concentrations for the agents. Thermal breakdown
WUSCHEL (WUS) is a homeodomain transcription factor produced in cells of the niche/organizing center (OC) of shoot apical meristems. WUS specifies stem cell fate and also restricts its own levels by activating a negative regulator, CLAVATA3 (CLV3), in adjacent cells of the central zone (CZ). Here we show that the WUS protein, after being synthesized in cells of the OC, migrates into the CZ, where
Haemophilia is an X-linked inherited recessive disorder affecting males. The increased risk of hemorrhage is explained by the deficiency in either coagulation factor VIII (haemophilia A) or IX (haemophilia B). The severity of haemophilia A and B is characterized by the bleeding pattern. For severe haemophilia bleeding is often spontaneous, mainly in muscles and joints. Since the 1950s the manifest
Background: Real-time perfusion (RTP) contrast echocardiography can be used during adenosine stress echocardiography (ASE) to evaluate myocardial ischemia. We compared two different types of RTP power modulation techniques, angiomode (AM) and high-resolution grayscale (HR), with Tc-99m-tetrofosmin single-photon emission computed tomography (SPECT) for the detection of myocardial ischemia. Methods:
This paper deals with organizational inscriptions of managerial cognitions elaborating on the emerging concept of network pictures. While previous studies on network pictures have concentrated on individual managers' cognitive views of business networks, this study operates on a focal company level (meso-level) and is concerned with how managerial cognitions are manifested in organizational artifa
This paper analyzes the effects of the interaction between technology adoption and incomplete enforcement on the extent of violations and the rate of abatement technology adoption. We focus on price-based and quantity-based emission regulations. First, we show that in contrast to uniform taxes, under tradable emissions permits (TEPs), the fall in permit price produced by technology adoption reduce
Western South America is subject to considerable inter-annual variability due to El Nio-Southern Oscillation (ENSO) so forecasting inter-annual variations associated with ENSO would provide an opportunity to tailor management decisions more appropriately to the season. On one hand, the self-organizing maps (SOM) method is a suitable technique to explore the association between sea surface temperat
This dissertation aims to investigate and analyze people's preparation for retirement. The study has been made through semi-structured interviews with 78 people born between the years 1931-1981 regarding their preparations for retirement. The analysis is based on the model Reflexive Planning for Later Life, coping, bounded rationality, behavioural finance and the concept of governmentality, and
The sex-dependent effect of environmental conditions on nestlings has been extensively studied in size dimorphic birds. Whether males or females are more sensitive to poor conditions is not yet clear; however, the degree of sexual size-dimorphism, brood size and their interactions seem to influence the pattern. Much less is known about sex-dependent environmental sensitivity in size-monomorphic sp
Cold and thermal neutrons used in neutrons scattering experiments are produced in nuclear reactors and spallation sources. The neutrons are cooled to thermal or cold temperatures in thermal and cold moderators, respectively. The present study shows that it is possible to exploit the poor thermalizing property of Pb-208 to design a broad spectrum moderator, i.e. a moderator which emits thermal and
Popular Abstract in Swedish Barn ar ofta bärare av luftvägsbakterien pneumokocker i de övre luftvägarna och det är barnen som anses vara den största reservoaren för bakterien i vårt samhälle. Vanliga pneumokockinfektioner såsom öron-, bihåle- eller lunginflammation föregås av att man bär på bakterien. De flesta barn som är bärare blir dock inte sjuka. Vuxna är mer sällan bärare av bakterien. PneuThe paediatric nasopharyngeal flora is regarded as the largest reservoir for Streptococcus pneumoniae, and the carrier state is always antecedent to infection and a prerequisite for dispersion of these bacteria. Pneumococci are the predominant aetiology of bacterial respiratory tract infections and a major cause of morbidity and mortality, in the most severe cases due to invasive pneumococcal dise
The aim of this research was to find out if it is possible to increase myocardial microvasular blood flow by applying a topical negative pressure source directly onto the myocardium. Topical negative pressure is a relatively new wound healing technique. When used in wound therapy, topical negative pressure has been shown to increase microvascular blood flow, to stimulate granulation tissue formati
I denna forskningsrapport presenteras studier som berör ungdomars arbetsmarknadsetablering. Stor uppmärksamhet ägnas offentliga regelverk och insatser som görs för att underlätta för unga individer att fullborda en gymnasieutbildning respektive att ta steget från skola till arbetsliv. Den nationella problembilden speglas och fördjupas via erfarenheter från tio olika kommuner. Sammantaget visar u
