Interactions between two like-charged macroions in the presence of their counterions confined in a cylindrical cell have been investigated by Monte Carlo simulations. The mean force and the potential of mean force (pmf) as a function of the macroion separation have been determined at conditions at which short-range attractions become significant. As the electrostatic coupling is increased, the nat

The historical development of company law in Sweden.

This paper gives an overview of the present knowledge regarding the interaction between the climatic conditions at the concrete surface and the corresponding conditions inside the concrete. The phenomena dealt with are those involved in frost damage, frost and salt scaling and reinforcement corrosion, such as temperature and moisture conditions in the near surface regions, carbonation and chloride

The effect of the simultaneous administration of norepinephrine and 5-fluorouracil (5-FU) on the uptake of radiolabelled 5-FU by liver tumours was studied in rats. Three different concentrations of 5-FU were used (15, 1.5 and 0.15 microgram/g body weight). The drugs were infused over a 30 min period via the hepatic artery, following cannulation of the gastroduodenal artery. The radioactivity in li

Neutron deficient (98)pd nuclei were produced in the Cr-50(Ni-58,2p2 alpha)(98) Pd reaction at a beam energy of 261 MeV. A revision and extension of the level structure of (98)pd is proposed. About 40 new transitions have been assigned to, and placed in the level scheme of this nucleus. A sequence of states are candidates for the negative parity 4-quasiparticle states built on the pi g(9/2)(-3)pi

Increased male age has been associated with significant reduction in pregnancy rates. This study investigated the association between age, the function of epididymal and accessory sex glands, and their relation to sperm motility. Ejaculates from 498 men assessed for infertility were analysed according to WHO [1999] guidelines. Seminal markers of epididymal (neutral alpha-glucosidase (NAG)), prosta

Amphiphilic polymers consisting of copolymethacrylates carrying about 26 wt % ethylene oxide [(EO)(n)] side chains of different lengths were used as matrices in gel electrolytes. The gel electrolytes were composed of 30 wt % copolymer and 70 wt % 1 M LiPF6 in a mixture of ethylene carbonate and gamma -butyrolactone (2/1 w/w). The coordination of lithium ions by the (EO)(n) side chains in competiti

The structure and organisation of the extracellular matrix, and in particular the axial alignment of type I collagen fibrils, are essential for the tensile strength of tendons. The resident tenocytes synthesize and maintain the composition of the extracellular matrix, which changes with age and maturation. Other components of the extracellular matrix include less abundant collagen types II, III, V

We have observed photons in the visible light range emitted from slow (2.0 keV/amu) highly charged Ar6+ ions which have captured one electron and transmitted through a Ni microcapillary target. Observed lines were identified by comparing with an ab initio calculation based on the multi-configuration Hartree-Fock method. (C) 2003 Elsevier Science B.V. All rights reserved.

Popular Abstract in Swedish I Sverige inträffar varje år c:a 1 500 självmord och minst 15 000 självmordsförsök. Självmordsbeteende är således ett problem som berör många människor i vårt samhälle. En grupp som löper en klart förhöjd risk att begå självmord är de personer som gjort självmordsförsök. "Självmordsförsökare" utgör dock en heterogen grupp av människor av olika ålder, kön, sociala omstänBetter understanding of suicidality may improve treatment and care of suicide attempters. This thesis aims at understanding suicidality by investigating suicide risk, sex differences and views of suicide attempters. Suicide risk factors (prospectively determined) differed between the sexes: Older age and high suicidal intent were female risk factors, whereas previous attempts and using a violent
