Except for hip fracture surgery, emergency surgery has been only exceptionally studied concerning thromboprophylaxis. There are, however, several reasons to believe the frequency to be fairly high and that the patient group would be in need of prophylaxis. This paper discusses various emergency situations and also gives the design for an ongoing controlled study on the effect of postoperative star

Direct estimates of C:N ratios of ectomycorrhizal (EM) mycelia growing in situ in forest soils have been obtained for the first time. The mycelial samples were collected from sand-filled mesh bags that were buried in the soil and incubated for 12-18 months in two Norway spruce forests in southern Sweden. At harvest the mesh bags were heavily colonized and the mycelia were extracted from the sand w

The microflora of the bile and wall of the gallbladder was prospectively investigated in 104 nonselected consecutive patients treated with early cholecystectomy for acute cholecystitis after an average hospital stay of 1.8 days. The chief purpose was to relate the findings of cultures to duration of the illness. Special attention was paid to anaerobic isolation techniques. The cultures yielded 107

As cardiovascular diseases have been the most common cause of mortality in the western world for decades, the demand for appropriate diagnostic methods is obvious. To facilitate the examination non-invasive methods are preferable since they do not require sensors within the circulation system. Ultrasonic Doppler is a frequently used technique in non-invasive hemodynamic studies. To increase the a

The Hartree-Fock-Bogoliubov (HFB) equation in a simplified model is solved in coordinate space with the correct asymptotic boundary conditions, in order to study the pair correlation in nuclei close to the neutron drip line. The occupation probability obtained in the HFB approach for lower-l orbits decreases considerably already when the binding energy of the corresponding Hartree-Fock (HF) one-pa

Popular Abstract in Swedish Samarbete är ett värdeladdat ord i svenskt välfärdsarbete och inom socialt arbete förespråkas samarbete ofta som något värdefullt och nödvändigt. Idag finns det en stor, om än fragmenterad, vardagskunskap om samarbete och samverkan. Vetandet präglas dock av ett okritiskt accepterande av samarbetets fördelar, samtidigt som många verksamheter visar att resultaten av samarCo-operation is highly valued in Swedish welfare work and joint efforts within and between healthcare and welfare organizations is not new in Sweden. For decades the authorities have been trying to organize and coordinate various social and medical efforts in the public sector at a central level. This thesis is focusing on the meaning of co-operation between professionals belonging to different or

The currant shoot borer, Lampronia capitella (Lep., Prodoxidae), is an important pest of currants, Ribes spp., in northern Europe. Oviposition was studied in cage experiments and the flight period was monitored in field studies using pheromone-baited traps. Blackcurrant, Ribes nigrum, was the host species in both studies. The total egg supply of females was on average 107 eggs and oviposition star

Popular Abstract in Swedish Vi kan inte avslöja innehållet i våra tankar direkt, så hur kan vi närma oss de underliggande kognitiva processerna? Om vi vill lära oss mer om vad som försiggår i vår tankevärld, måste vi göra det indirekt, med hjälp av tankarnas yttre manifestationer. Det finns olika metoder som man kan ta till sin hjälp. I min avhandling kopplar jag ihop två ämnesområden, lingvistik In this thesis, I connect two disciplines, linguistics and vision research, and combine two methods, spoken language protocols and eye movement protocols, in order to cast light on the underlying cognitive processes. In a series of studies, I investigate the processual aspects of picture viewing and picture description. On the one hand, eye movements reflect human thought processes. It is easy to

Riverine high molecular weight dissolved organic material (HMWDOM) >1 kDa contains varying amounts of nitrogen. This nitrogen is partly available for growth of phytoplankton and can therefore contribute to algal bloom formation. However, there is a lack of knowledge on species-specific utilization efficiency of this HMWDOM-bound nitrogen. A specific question is whether this nitrogen can be used by

The interaction between troponin C (TnC) and troponin I (TnI) is essential for the regulation of muscle contraction. There are several binding sites for TnI on TnC that are differentially occupied depending on the phase of the contraction/relaxation cycle. TnI and TnC interact in an antiparallel fashion with each other. The C-domain of cTnC and the N-domain region of cTnI(residues 33–70) always in

Modern district heating systems, a carbon lean technology, involves dual usage of the energy due to the possibility to redistribute heat derived from numerous sources, such as industrial processes, refuse incineration, geothermal sources and combined heat and power plants. Such heat source flexibility facilitates the optimal usage of energy resources by varying the amount of purchased heat dependi

Pulse height versus energy calibrations of a Si p-i-n diode and a Au-/n-Si surface barrier detector have been studied for heavy ions with atomic number (Z(1)) from 3 to 79 in a range from 0.1 to 0.8 MeV per nucleon as a function of bias voltage and detector tilting angle. The detector response is simultaneously measured using a time of flight-energy elastic recoil detection analysis set-up with re

Here we present results from a field experiment in a sub-arctic wetland near Abisko, northern Sweden, where the permafrost is currently disintegrating with significant vegetation changes as a result. During one growing season we investigated the fluxes of CO2 and CH4 and how they were affected by ecosystem properties, i.e., composition of species that are currently expanding in the area (Carex rot

Coronary heart disease (CHD) is a common condition associated with a high mortality. There is now growing evidence that erectile dysfunction (ED) in men may be a suitable marker of sub-clinical cardiovascular disease, identifying patients at high risk for future CHD. We investigated the association between CHD risk factors and ED during a period of 25 years, in a population based cohort of men, a
