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

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

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

Ionizing radiation is a well-known risk factor for sarcoma development. To investigate whether radiation-associated sarcomas are characterized by chromosome aberrations that distinguish them from de novo sarcomas, we identified those patients in our series of more than 500 cytogenetically abnormal sarcomas that fulfilled the following criteria: (1) each patient should have been irradiated for anot

The self-shrinking generator was introduced in 1994. It is based on the idea behind the shrinking generator and despite its simplicity it has remained remarkably resistant to efficient attacks. Several known plaintext attacks have been proposed on the generator, some operating on a short keystream and others requiting a longer sequence to succeed. In this paper, two new attacks on the self-shrinki

The regional distribution and timing of spring passage of the Bar-tailed Godwit Limosa lapponica in Sweden is reported (160,300 observed birds in 1976-1995). Birds were observed in most provinces, with the highest concentrations in southernmost Sweden. Timing of passage was bimodal, with distinct peaks in the middle and end of May, suggesting that two separate populations are passing. The peak in

The role of caldesmon in the regulation of smooth muscle contraction was investigated in chemically skinned smooth muscle fibres from the guinea-pig taenia coli. A 19-kDa C-terminal fragment of caldesmon gave a minor (

Carbon-oxygen-related complexes in Si crystals enriched with either oxygen (O-16,O-18) or carbon (C-12, C-13) isotopes were investigated by Fourier Transform infrared absorption spectroscopy. The samples were irradiated with electrons at room temperature as well as at elevated temperatures (400-600 degreesC). The oxygen isotopic shifts of the local vibrational modes related to C3 and C4 centers we

1,5-Anhydro-D-fructose (AF) is a monosaccharide occurring in edible morels, red seaweeds and certain mammalian tissues. It can be formed directly from starch and glycogen in vivo by alpha-1,4-glucan lyase (EC 4.2.2.13). In this study, the toxicity, absorption and metabolism of AF using bacteria, mammalian cells, rat and mouse models were examined. In Ames test, AF showed no genotoxicity using five

The transverse momentum dependence of the azimuthal anisotropy parameter v(2), the second harmonic of the azimuthal distribution, for electrons at midrapidity (vertical bar eta vertical bar < 0.35) has been measured with the PHENIX detector in Au+Au collisions at root s(NN) = 200 GeV. The measurement was made with respect to the reaction plane defined at high rapidities (vertical bar eta vertical

Purpose: To investigate whether previously reported changes in protein expression of middle and long (M/L) and short (S) wavelength cone opsin pigments in cultured retina are correlated with changes in their gene expression. Additionally, to elucidate the importance of a functional retinal pigment epithelium for the development of photoreceptor outer segments. Methods: Neonatal rat retinas were ma

Full-length and truncated forms of a modular thermostable xylanase (EC 3.2.1.8., glycoside hydrolase family 10) were used in bleaching sequences of hardwood and softwood kraft pulps. Enzymatic treatment led to brightness gains of all pulps but the result depended on the pulp source. The presence of the additional domains in the full-length enzyme (including carbohydrate-binding modules) did not im

Event-by-event fluctuations in the multiplicities of charged particles and photons, and the total transverse energy in 158A GeV Pb+Pb collisions are studied for a wide range of centralities. For narrow centrality bins the multiplicity and transverse energy distributions are found to be near perfect Gaussians. The effect of detector acceptance on the multiplicity fluctuations has been studied and d

In our clinical research, we have drawn the conclusion that meaningful long-term (> 6 months) pain relieving effects can be seen in a proportion of patients suffering from nociceptive pain. What are the mechanisms behind this? From the existing experimental data, some important conclusions can be drawn: A significant proportion of the animal research only represents short-term hypoalgesia probably
