Hormonal replacement therapy (HRT) is generally regarded as first choice for pharmacological prevention of osteoporosis in women. We reviewed recent studies of HRT regimens and selective oestrogen receptor modulators (SERMs), including controlled trials of at least one-year duration published since 1995 until February 2000 providing data on bone mineral density (BMD) or fractures. Natural and synt

BACKGROUND/AIMS: After acute self-limited hepatitis B virus (HBV) infection, serological loss of viral antigens and appearance of anti-HBs is generally believed to signify viral clearance. Latent and occult HBV infection appearing decades after self-limited hepatitis B has not been reported, nor has the evolutionary rate of HBV DNA over the same observation period. METHODS: DNA from serum and leuk

The two most frequently examined biomarkers in the diagnosis of dementia are cerebrospinal fluid (CSF) tau and beta-amyloid(1-42) (Abeta(1-42)). An assay for tau phosphorylated at threonine 181 (phospho-tau) has recently been developed. We studied these three markers in patients with possible Alzheimer's disease (AD; n = 23), probable AD (n = 50), AD with relevant cerebrovascular disease (AD with

Evidence for a novel route of adult hematopoietic stem cell lineage commitment through Lin(-)Sca-1(+)Kit(+)Flt3(hi) (LSKFlt3(hi)) lymphoid-primed multipotent progenitors (LMPPs) with granulocyte/monocyte (GM) and lymphoid but little or no megakaryocyte/erythroid (MkE) potential was recently challenged, as LSKFlt3(hi) cells were reported to possess MkE potential. Herein residual (1-2%) MkE potentia

Transcranial magnetic stimulation (TMS) with weak (micro Tesla) complex waveform fields have been claimed to evoke the sensed presence of a sentient being in up to 80% in the general population. These findings have had a questionable neurophysiological foundation as the fields are approximately six orders of magnitude weaker than ordinary TMS fields. Also, no independent replication has been repor

In the early 1970’s, about 80 ha of rich fen, meadows and wet forest on the margins of the largeand pristine raised bog ‘Komosse’ in Southern Sweden were drained by ditches to promote spruce(Picea abies) growth and forestry production. Draining had a dramatic impact on forest productionon the nutrient-rich peaty soils downhill from the ditches. In 40 years, most of the meadows andfens had turned i

Biomass combustion in grate fired furnaces is an important approach to convert renewable biomass fuel to heat and electricity. It is not only used in the Swedish energy industry but also by a great number of Swedish households for domestic heating. Burning biomass has the advantage of being CO2 neutral. However, it suffers from several difficulties, for example, the poor combustion efficiency ? th

The deactivation of alumina supported platinum and iron catalysts by hexamethyldisiloxane (HMDS) exposure has been investigated. Three catalysts (Pt/Al2O3, Fe/Al2O3 and Fe/Pt/Al2O3) were prepared and the influence of short- and long-term deactivation on the activity for oxidation of ethyl acetate was studied. The catalysts were characterized using BET, ICP-AES, XPS, SEM and CO chemisorption. The d

In contemporary Sweden, welfare professionals are mobilising to signal that they lack the preconditions to carry out their work in line with the politically stated mission and professional ethics. Following a seminar in which welfare professionals shared their views on the working conditions, this study explores action strategies for welfare professionals who seek to influence the policy agenda. T

The use of Reinforcement Learning (RL) to design controllers for safety critical systems is an important research area. On the one hand, RL can function in and adapt to complex and changing environments without requiring a model of the system. On the other hand, in such systems robustness is of high importance, as well as ways to guarantee and certify a level of robustness. This project investigat

This paper examines the downward trend in the U.S. labor share of income, which is shown to have declined significantly over the last two decades. This phenomenon is in direct contradiction with standard neoclassical growth theory, which postulates constant factor shares of income. Increased trade with low-income countries, financialization, and the decline of labor unions are some of the explanat

The purpose of the study is to see differences and development of two institutions for social care (work science) in two countries - the University of Lodz, Polen, and the University of Lund, Sweden. The central question is, if there is any convergence between these Institutions for Social care. The method has been to use both earlier research and to have two interviews. I did interviews with tw

This essay investigates a case of public interaction in the field of climate change. The three levels of public management in Skåne, Sweden (municipality, regional and county) are currently engaged in a form of cooperation to bring together the three forms of political responsibility in one committee. It is a new approach to the climate issue and the aim of this thesis is to evaluate the theoretic

This paper is a case study of the Swedish digital diplomacy activities in Egypt on social media. The author investigates how we can understand the purpose of the digital diplomacy carried out by the Swedish embassy and the ambassador in Egypt, by studying its content on the social media Facebook, Instagram and Twitter. Digital diplomacy in this study means the use of social media within the framew

Generella skatteflyktsregler, eller GAARs (general anti-avoidance rules), är legislativa åtgärder mot skatteflykt. GAARs typiska struktur består av två förutsättningar: skattebetalarens syfte och lagstiftarens syfte. Om det huvudsakliga syftet med en transaktion är att minimera skatteutgifter på ett sätt som lagstiftaren inte hade avsett får transaktionen bortses ifrån vid beskattningen. GAARs potGeneral anti-avoidance rules, or GAARs, are legislative measures against unacceptable tax avoidance. The typical structure of a GAAR refers to two prerequisites: the intent of the taxpayer and the intent of the legislator. If the main purpose of a transaction is to minimize tax expenses in a way unintended by the legislator, the transaction can be disregarded from a tax perspective. The potentiall

The aim of this essay is, with reference to a close study on the negotiation delegations of the Tenant Association, to examine the principals of democracy in relation to distribution of power and participation, efficiency and professionalism. This is done with the intention to understand the Tenant Association's view on its own commission as negotiator, according to democracy. The investigatio
