Möjlig lösning av bristen på bloddonationer med hjälp av outforskat havrehemoglobin. Hemoglobin är främst förknippat med blod i oss människor och andra djur, men tänk om någon berättade att det syretransporterade proteinet också finns i växter. Underligt, eller hur? Växter har ju inget blod men ändå finns det där. I denna rapport beskrivs identifieringen av tre nyfunna havrehemoglobin som har likHemoglobin is mainly viewed as an oxygen and carbon dioxide carrier in the blood of animals and thus essential for life as we know it. During the course of evolution, plants have also developed versions of this protein, for similar and different purposes, such as regulation of nitric oxide levels. A lot of research has been put into characterization of hemoglobin from monocots, including rice, bar

En jämförelse mellan singel-chipet och dual-chipet: ny tillämpning för akustisk infångning av celler och partiklar Mikrofluidik är ett expansivt område som banar väg för utveckling av ny mikroteknologi inom det medicintekniska området. Genom att studera och försöka förstå hur vätskor och mindre partiklar beter sig på mikroskalan kan man finna lösningar till mer effektiva analysmetoder på exempelvAbstract Microfluidics is the field where the behavior of fluids is studied in very small channels, and small means that the size of the channels normally is only a couple of hundred microns. Fluids in the µL/nL/pL range are handled in microfluidics. There´s a difference in the behavior of fluids on the microscale compared to the macroscale. This difference, taken into consideration yields severa

Brottslighet och särskilt organiserad brottslighet, utgör ett problem för samhället i Sverige men också i andra länder. I statsmaktens arbete mot kriminalitet är hindrande av möjligheterna till penningtvätt, ett viktigt inslag. Penningtvättsåtgärder kan nämligen allmänt beskrivas syfta till att dölja eller omsätta vinning av brottslig verksamhet. Studier har visat att omfattande summor pengar frånCrime and in particular organized crime, is a problem for the society in Sweden but also in other countries. Obstruction of opportunities for money laundering is an important element to the authorities in their struggle against crime. Money laundering can generally be described as seeking to conceal or convert the proceeds of criminal activity. Studies have shown that substantial amounts of money

The unfolding of the COVID-19 pandemic has been very difficult to predict using mathematical models for infectious diseases. While it has been demonstrated that variations in susceptibility have a damping effect on key quantities such as the incidence peak, the herd-immunity threshold and the final size of the pandemic, this complex phenomenon is almost impossible to measure or quantify, and it re

Iggesund Paperboard Limited works in an increasingly competitive and cost-focused industry. The production is very customised and besides the different product variants some customers also have special requests, which mean activities that fall out of the normal process. The contribution system does not identify the additional costs that depend on the special customer requests. The purpose with th

Problems: What is human capital? How is a knowledge worker’s human capital cultivated? In what way can an impresario help a knowledge worker to cultivate and capitalise on his or her human capital? Purpose: The purpose of this paper is to explore the impresario approach on talent with today’s knowledge workers and their human capital. A visualisation of such an approach might lead to ways of assis

The main purpose of this essay was to study the program "Nationellt stöd för kunskapsutveckling inom socialtjänsten" ("National support for knowledge development within the social services") from the National Board of Health and Welfare on the basis of how such a development, as represented by the program, could affect clients' possibilities to participation and influence w

Att företag köper upp andra företag är en viktig del av näringslivet. Det är ett sätt för företag att snabbt växa och tillskansa sig värden som gör företaget starkare. En företagsöverlåtelse är dock inte riskfri. Den är ofta kostsam och det finns inga garantier för att köpet lönar sig. Det köpande företaget kan dock till viss del skydda sin investering genom att i överlåtelseavtalet föra in en konCorporate acquisitions are a vital part of the business world. They are a way to ensure growth. They are also a good way of adding values to the company, which in turn makes the company stronger. However, an acquisition is not risk free. It is often expensive and there are no guarantees that the acquisition will be profitable in the end. The buyer can to some extent protect its investment with a n

This report is a fire safety evaluation of Norrbottensteatern in Luleå, Sweden. The report was carried out as a part of the education program for fire engineers. The main purpose was to analyse the safety regarding evacuation in case of fire, and to present a proposal of measures if necessary. The theatre, built in 1986, is a four storey building and can hold more than 600 guests in its three salo

In this article we present a concept for a ubiquitous service that allows memories to be saved and stored during an individual's lifetime and later, after death, for those digital remains to be published and experienced at the specific geographic location where they were created. Through this concept we explore ways to combine modern technology with century old habits at the end of life. We as

The objectives of this study were: (1) to assess nutrient flows and balances at land management systems and cropping seasons levels, and (2) to determine rate of nutrient depletion. The study was conducted in dry lands of Northern Kordofan, Sudan, at El Demokeya Forest Reserve (lat.13° 16′ ′′ ′N; long. 30° 29′ ′′ ′E, and alt. 560 m), over three cropping seasons (2002, 2003 and 2004). Flows and

The results of structural and magnetic characterization of GaMnSb layers grown on GaSb(0 0 1) and GaAs(1 1 1) substrates are presented. The presence of hexagonal, highly oriented MnSb inclusions embedded in GaSb matrix has been demonstrated. The lattice parameters of these inclusions were the same as those for bulk MnSb for the layers grown on GaSb(1 0 0) substrate while for the layers grown on Ga

The effect of different process stages on microstructural and visual properties of dark chocolate was studied. Samples were obtained at each phase of the manufacture process: mixing, prerefining, refining, conching, and tempering. A laser light diffraction technique and environmental scanning electron microscopy (ESEM) were used to study the particle size distribution (PSD) and to analyze modifica

Context. Spectral-line asymmetries (displayed as bisectors) and wavelength shifts are signatures of the hydrodynamics in solar and stellar atmospheres. Theory may precisely predict idealized lines, but accuracies in real observed spectra are limited by blends, few suitable lines, imprecise laboratory wavelengths, and instrumental imperfections. Aims. We extract bisectors and shifts until the "ulti

Background: Although cardiovascular disease is thouht to be common in cirrhosis, there are no systematic investigations on the prevalence of electrocardiographic (ECG) abnormalities in these patients and data on the occurrence of post-transplant cardiac events in comparison with the general population are lacking. We aimed to study the prevalence and predictors of ECG abnormalities in patients wit

Liquid displacement of model and industrial fluids in pipes was successfully investigated using the in-line rheometer concept based on the combination of Ultrasound Doppler Velocity Profiling (UVP) and the pressure difference (PD) technique. The velocity profile development, related mixing zone and real-time changes in rheology were monitored when one fluid was displaced by another with different

Background and purpose Spontaneous osteonecrosis of the knee (SPONK) is a painful lesion in the elderly, frequently leading to osteoarthritis and subsequent knee surgery. We evaluated the natural course and long-term consequences of SPONK in terms of need for major knee surgery. Methods Between 1982 and 1988, 40 consecutive patients were diagnosed with SPONK. The short-term outcome has been report

Prophylaxis and treatment with antiretroviral drugs, a consequent low viral load, and the use of elective Caesarean section, are factors that radically decrease the risk of HIV transmission from mother to child during pregnancy and delivery. The availability of new antiretroviral drugs, updated general treatment guidelines and increasing knowledge of the importance of drug resistance, have necessi

The management of primary gastrointestinal stromal tumours (GISTs) has evolved with the introduction of adjuvant therapy. Recently reported results of the SSG XVIII/AIO trial by the Scandinavian Sarcoma Group (SSG) and the German Working Group on Medical Oncology (AIO) represent a significant change in the evidence for adjuvant therapy duration.
