On homogeneous density functions

We consider homogeneous density functions for proving almost global attractivity of the zero equilibrium in a homogeneous system. It is shown that the existence of such a function is guaranteed when the equilibrium is asymptotically stable, or in the more general case, when there exists a nonhomogeneous density function for the same system satisfying some reasonable conditions.

A new species of Cordyla Meigen from Norway (Diptera: Mycetophilidae)

A new species of fungus gnats in the genus Cordyla Meigen, 1803, C. bomloensis sp. n., is described based on adult material from southwestern Norway. Both the male and the female are described, photographed and their terminalia figured. The new species belongs in the C.fusca-group. It seems to be most closely allied to C. brevicornis (Staeger, 1840) and C. pusilla Edwards, 1925 from which it is di

Evidence of a Late Precambrian (637 Ma) deformational event in the Caledonides of northern Sweden

The Caledonian nappes in Scandinavia record two main phases of early Paleozoic metamorphism, but their pre-Caledonian tectonothermal history and paleogeographic position are largely unknown. Here we present a U-Pb age of 637+/-3 Ma for metamorphic titanite in the 1776+/-4 Ma (zircon age) Skarja granitic gneiss in northern Sweden. The titanite age is interpreted to represent a Neoproterozoic tecton

Discrimination of men with prostate cancer from those with benign disease by measurements of human glandular kallikrein 2 (HK2) in serum

PURPOSE: To investigate the clinical value of measuring human glandular kallikrein 2 (hK2) compared with free and total prostate specific antigen (PSA-F and PSA-T) in serum from patients with prostate disease. MATERIALS AND METHODS: Serum from healthy controls, from men with benign prostate hyperplasia (BPH), clinically localized prostate cancer (PCa), and advanced PCa were analyzed for hK2 (using

On argument displacement in English and Scandinavian

The displacement operations that Chomsky (1999) terms ‘themati¬zation/extraction’ and takes to be phonological of nature, are truly syntactical operations. Concerning leftward displacement, I add another argument for its syntactic nature to those already known from the literature. My argument is based on the behaviour of Mainland Scandinavian bare singular nominals, which neither move to Spec-IP

A hyphothesis on the mechanism of surface scaling due to combined salt and frost attack

A hypothesis on the mechanism of "salt-scaling" of porous building materials based on theories for frost heaving in soils and observations made by Powers and Helmuth /1953/ is described. Though the text mainly deals with cement based materials, the mechanism described should be valid for any brittle, porous material. A simplified calculation of possible scalings shows that the hypothesis predicts

Use and interpretation of on/off diaries in Parkinson's disease.

Objective: To explore the use and interpretation of self reported on/off diary data for assessment of daily motor fluctuations in Parkinson’s disease. Methods: 26 consecutive non-demented patients with fluctuating Parkinson’s disease received standardised training on how to fill out the four category CAPSIT-PD on/off diary, followed by four hours of clinical observation and four weeks of daytime

Immunohistochemical loss of the DNA mismatch repair proteins MSH2 and MSH6 in malignant fibrous histocytomas

Purpose: Soft tissue sarcomas (STS) account for less than 1% of all malignancies and constitute a heterogeneous tumor entity in which malignant fibrous histiocytomas (MFH) represent one-third and are characterized by a lack of type-specific differentiation. A defective mismatch repair (MMR) system cause the familial cancer syndrome hereditary non-polyposis colorectal cancer (HNPCC), and since occa

Crystal structures and supramolecular assembly of 1 : 2 piperazine with o- and p-nitrophenol

1:2 Cocrystals of piperazine (PPN) with o- and p-nitrophenol (oNPH and pNPH) were obtained from aqueous solution. The co-crystal structure of PPN, 2pNPH, and 2H(2)O is triclinic space group P (1) over bar: a = 6.401(1) Angstrom, b = 6.7515(1) Angstrom, c = 11.219(1) Angstrom, alpha = 100.37(1)degrees, beta = 97.10(1)degrees, gamma = 99.99(1)degrees,V= 465.5(1) Angstrom(3), Z = 2. Refinement led to

The first case of the Sanfilippo type C syndrome in Scandinavia

A Swedish patient with typical symptoms of the Sanfilippo Syndrome (Mucopolysaccharidosis III) is described. The early onset of the disease, the presence of hepatomegaly, early dementia and the absence of umbilical bernia are consistent with the subgroup Sanfilippo A. Enzyme studies indicate the diagnosis Sanfilippo C, and thus the patient represents a more severe form of this subgroup than any of

3G of Sweden – technological growth and sustainability issues

The article discusses the construction of 3G infrastructure under four themes from planning and sociology of law perspectives. This includes the design of the initial license procedure, the 3G-developments physical aspects in a different actors driving forces point of view and the practical sides of sustainability issues at both regional and local level. Public concern over electromagnetic radiati
