Smoluchowski's coagulation equation is studied for the kernel K (u, v) = E(u(alpha)v(beta) + u(beta) v(alpha)) with real, non-negative alpha, beta and E, using gamma distributions with a singularity at zero volume as initial size spectra. As the distribution parameter of the gamma distribution, p, approaches its lower limit (p -> 0) the distribution becomes similar to pv(p-1) 1 for small v. Asympt

BACKGROUND: Increased pulmonary vascular resistance is frequently seen after lung transplantation. Thromboxane A2 is a potent vasoconstrictor of pulmonary arteries. Thromboxane-elicited vasoconstriction can ben counteracted by prostacyclin. The effects of lung transplantation on the biosynthesis of these substances were investigated. METHODS: Pulmonary artery flush perfusion with a low-potassium d

Psoriasis (Ps) and psoriasis arthritis (PsA) are poorly understood common diseases, induced by unknown environmental factors, affecting skin and articular joints. A single i.p. exposure to mannan from Saccharomyces cerevisiae induced an acute inflammation in inbred mouse strains resembling human Ps and PsA-like disease, whereas multiple injections induced a relapsing disease. Exacerbation of disea

Polarization spectroscopy in the mid-infrared (IRPS) has been applied to the detection of acetylene molecules making use of the asymmetric C-H stretching vibration at around 3 μm. The infrared laser pulses were produced through difference frequency generation in a LiNbO₃ crystal pumped by a Nd:YAG and dye laser system. By directly probing the ro-vibrational transitions with IRPS, sensit

Hereditary cystatin C amyloid angiopathy is a dominantly inherited disorder, characterized by dementia, paralysis, and death from cerebral hemorrhage in early adult life. A variant of the cysteine proteinase inhibitor, cystatin C, is deposited as amyloid in the tissues of the patients and their spinal-fluid level of cystatin C is abnormally low. The disease-associated Leu-68-->Gln mutant (L68Q) cy

The inability of the Security Council to consistently apply The Responsibility to Protect has drawn criticism towards the council, accusing it of a western bias. If true, this could prove a serious dent in the UN’s ambition to maintain international peace and security according to the seventh chapter of the UN charter. The aim of this study is to compare and analyze different conflicts in order to

Background. Age-specific incidence rates for breast cancer in low-risk and high-risk ethnic populations differ by age at which the incidence maximum is reached: around 50 years in low-risk populations and over 60 years in high-risk populations. The interpretation of these differences remains unsettled, one line primarily referring to biological differences, the second one to cohort effects of rapi

The effect on a model drug delivery system when adding a drug, lidocaine, has been studied. Temperature and concentration dependence of a nonionic microemulsion with part of the oil, 1 and 10 vol. %, substituted with drug has been investigated. A nonionic oil-in-water microemulsion consisting of CH3(CH2)(11)(OCH2CH2)(5)OH, (C12E5), decane, water and the drug (lidocaine) that has been used to subst

Based on a series of interviews with young activists working in both parliamentarian and extra-parliamentarian contexts, this chapter underscores that political purposes steer the use of communication technology. This is an explicit position gainst technological determinism. The two different categories of activists generated two different kinds of civic cultures.

"Zalmoxis" is a dramatic poem in which each character autonomously structures his own discursive lyric, expressing thus a variety of concepts over the spiritual foundation of the Dacians. The charm of each nuance in part relates in the last instance, the mode in which the author understands the proper structure of the actual dramatic perspective above the revolt of our non-Latin foundation. The ne
