The effect of moderate hypoglycemia (p-glucose, 2.0 +/- 0.3 mmol/L; mean +/- SD) on regional cerebral blood flow (rCBF) was studied in a group of 10 healthy, right-handed men (aged 23 to 28 years) using an intravenous xenon 133 single photon emission computed tomography technique (SPECT). After 10 minutes of hypoglycemia, global CBF had increased to 46.3 +/- 9.6 mL/100 g/min compared with the init

In the study of economic-geographic structures, the shifting focus from the national state to the city and its region has highlighted the lack of reliable interurban data sets. The abundance of usable data sets on international structures and ?ows has no counterpart when studying interurban relations, which makes it hard to draw any extensive conclusions regarding the structure of world city netwo

This report has a two-fold objective. -To identify the changing risk management needs in the private and public sectors and the corresponding needs for development of risk analysis methods and related practices. -To list examples of projects where Nordic co-operation between industry, authorities and universities can be effective for increasing the contribution of risk management to industrial gro

High-spin states in the neutron-deficient isotope Cd-104 were populated using the Cr-50(Ni-58,4p)Cd-104 reaction at a beam energy of 250 MeV The level scheme has been extended using triple gamma-ray coincidences to a spin of 29h and an excitation energy of 18.2 MeV. Several collective structures involving the excitation of h(11/2) neutrons have been observed to spins approaching 30h. The high-spin

Advancing on preliminary research, the aim of this work was to further study how partial air dehydration applied to fruit pieces before freezing, alone or in combination with osmo-dehydration, could improve not only quality of strawberry slices used in yogurt preparation but also yogurt characteristics. Raw (NT), air-dehydrated (D), and osmo-air-dehydrated (OD) strawberry slices (cv. Tethis) were

Popular Abstract in Swedish Avhandlingen behandlar ekonomisk tillväxt och finanspolitik. Med ekonomisk tillväxt avses tillväxttakten i BNP – det sammanlagda värdet av alla varor och tjänster som produceras för slutlig användning i ett land – och med finanspolitik avses handhavandet av de offentliga finanserna. Efter ett introduktionskapitel följer fem kapitel som är fristående från varandra. De trThis thesis deals with the two subjects economic growth and fiscal policy. The first three chapters after the introduction are theoretical approaches to the determination of long-run growth. In each of these chapters, the ability of fiscal policy to influence long-run growth is examined as well. The next chapter relates the development of GDP in the long run to the financial system. The final chap

We performed a detailed census of the breeding population of Barred Warblers Sylvia nisoria in the Ottenby area on the southernmost part of the island Oland, SE Sweden, in the years 1999 and 2000. The number of territories in the study area was similar to the census conducted in 19711975, although the distribution of territories had changed. In 1999-2000 most territories were located in the grazed

PURPOSE AND MATERIAL: The aim of this work was, firstly, to compare different manufacturer-provided MRA sequences in a 1.0 T MR unit, with respect to the visibility of an artificial stenosis in a flow phantom and, secondly, to evaluate the same sequences in healthy volunteers with respect to S/N ratio levels and practical in vivo implementation routines. METHODS: The studied sequences were 2D and

In order to clarify the origins and pathways of vasoactive intestinal polypeptide (VIP)-containing nerve fibers in cerebral blood vessels of rat, denervation experiments and retrograde axonal tracing methods (true blue) were used. Numerous VIP-positive nerve cells were recognized in the sphenopalatine ganglion and in a mini-ganglion (internal carotid mini-ganglion) located on the internal carotid

The effects of cultivar (n = 4), root weight (n = 4), storage (S months) and boiling (7 min) and their interactions on the content of dry matter and carbohydrates were studied and ranked in carrots. Boiling had the greatest effect and had an influence on all variables except the ratio between sucrose and the monosaccharides glucose and fructose. The choice of cultivar was also of great importance

The thesis consideres the molecular events that take place in the cerebral arteries following a stroke. The degree and temporal course of reperfusion following a stroke is pivotal for the survival of the neuronal tissue in the penumbra. Previous investigations have revealed upregulation of contractile receptors, a putative factor in the blood flow reduction following stroke that can could augment

Popular Abstract in Swedish Människan är uppbyggd av ett stort antal celler. För att kroppens olika organ ska kunna samverka och för att kroppen ska kunna fungera som en helhet, måste de olika cellerna kommunicera med varandra. Cellernas kommunikationssystem är uppbyggt av mottagare, s.k. receptorer, på de olika cellernas yta och signaler som skickas runt mellan cellerna. Receptorerna och signaleThe chemokine receptors CCR5 and CXCR4 are required, together with CD4, for the entry of HIV-1 into target cells. CCR5 using HIV-1 dominates during transmission and the asymptomatic phase of infection. During progression, virus phenotypes with the ability to use CXCR4 emerge in about 50% of infected individuals. Individuals continuously harbouring CCR5-restricted isolates still progress to AIDS. D

One general class of attacks on stream ciphers is correlation attacks. Most of previous results regarding performance of correlation attacks have been based entirely on simulations. In this paper, we use random coding bounds for convolutional codes to give a theoretical analysis of a previously proposed correlation attack based on convolutional codes. The results from the theoretical derivation ar
