The most basic assumption of the classical nucleation theory (CNT) is to treat nucleus/liquid surface energy, r, as a macroscopic property having a value equal to that of a planar interface, r1. Therefore, when the CNT is used to analyze experimental data, the size dependence of surface energy is often neglected. To date, there has been no reliable method to measure the surface energy of the nu...

Mikilvægt er að standa vörð um jafnrétti kynjanna á tímum Covid 19 þar sem búast má við bakslagi, bæði vegna þess staða undirskipaðra hópa versnar enn frekar og óvissutímum hætta jafnréttisáherslur mæti afgangi. Í greininni eru tilkynningar rektors Háskóla Íslands til nemenda starfsfólks í kórónuveirufaraldrinum greindar út frá sjónarmiðum kynjajafnréttis. Gögn rannsóknarinnar samanstanda af 96...

Background and aims—Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease of unknown aetiology. Abnormalities in immune regulation and genetic associations suggest that PSC is an immune mediated disease. Several polymorphisms within the tumour necrosis factor á (TNF-á) and interleukin 10 (IL10) promoter genes have been described which influence expression of these cytokine...

Aims—To investigate the expression of á, â, and ã catenins in oropharyngeal and hypopharyngeal squamous cell carcinoma and their relations to each other, as well as to clinical data, tumour diVerentiation, and prognosis. Methods—Primary tumours for analysis were obtained from 138 patients diagnosed with squamous cell carcinoma of the oropharynx or hypopharynx between 1975 and 1998 in eastern Fi...

The aim of this article is to present new inequalities which improve some gamma function inequalities of H. Alzer, Á. Baricz and N. Elezović et al. Mathematics subject classification (2000): 26D07, 33B15.

Objective—To examine the eVect of á tocopherol and â carotene supplementation on the incidence of age related cataract extraction. Setting—The Alpha-tocopherol Betacarotene (ATBC) Study was a randomised, double blind, placebo controlled, 2×2 factorial trial conducted in south western Finland. The cataract surgery study population of 28 934 male smokers 50–69 years of age at the start. Intervent...

We revive the long standing Boltzmann-Loschmidt polemic which confronts irreversible Thermodynamics with reversible Mechanics. While this is solved within classical physics by the theory of Chaos, until now, there is no quantum de ̄nition of dynamical chaos. A nice possibility o®ered by NMR is to invert the direction of time (quantum Loschmidt daemon) in a many-body spin system. The e±ciency of ...
