Let X-1, X-2,... be independent and symmetric random variables such that S-n = X-1+...+ X-n converges to a finite valued random variable S a. s. and let S* = sup(1 <= n
Experimental studies of x-ray photoelectron and Co Lalpha x-ray emission spectra of the ZnS:Co semiconductor were carried out. It was established that Co ions are present in isovalent Co2+ configuration and that the Co 3d impurity states are localized above the top of the valence band by 1.0 +/- 0.2 eV.
This paper discusses the use of a transconductor, first proposed by Nauta for high frequency applications, in low frequency CMOS g(m) - C bandpass filters. The behavior of the transconductor is examined in detail, showing that the robust implementation of higher-order low-voltage filters is possible for center frequencies in the lower megahertz region. The experimental results are presented of the
Background and Purpose - The causes of death of patients with cerebral venous thrombosis (CVT) have not been systematically addressed in previous studies. We aimed to analyze the causes and predictors of death during the acute phase of CVT in the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) to identify preventable or treatable causes. Methods - ISCVT is a multinational,
A compilation of available test results relating to the strength of glulam beams with holes is presented. A total of 182 individual tests from 8 different sources are described concerning material, test setup and recorded crack loads and failure loads. A brief description of some available methods for strength analysis of timber is given and specific calculation approaches for the strength of glul
A new eight-week introductory course to the medical program has been developed and launched. The core idea is to give the students an overview of the program in order to understand how its different parts are interrelated. Central themes include research as part of clinical practice, the role of the doctor as a professional and the different working methods of the program, in particular the proble

A screen oriented editor is described. The report contains an English summary followed by a detailed description in Swedish.
Two cyclomaltodextrinases (CDase) of thermophilic origin were investigated for their action on cyclodextrins. Although most CDases known today are made up of at least homodimers, one of the enzymes studied was shown to be a monomer in solution, while the other one was a dimer. Interestingly, the dimeric enzyme had a much superior selectivity for a cyclodextrin substrate compared to its monomeric h
Objective. Although deep vein thrombosis (DVT) and pulmonary embolism (PE) are manifestations of the same disease, far from all patients develop PE. Our objective was to investigate risk-modifying factors. Setting, subjects and design. Between 1970 and 1982, 23 796 autopsies, representing 84% of all in-hospital deaths in the Malmo City population, were performed, using a standardized procedure. In
Historical archaeology in the present : Personal reflections on the subject, now that medieval archaeology at Lund University from January 2005 has been transformed into an historical archaeology.
Resonant Auger electron spectra of core excited O-3 (O(F)1s(-1) 2b(1)(1)) are presented for the first time. The photoionization valence spectrum with sample purity and resolution superior to those published is presented. The first direct experimental evidence for the (C) over tilde (2) B-1 state of O-3(+) is found. Ab initio calculations of the resonant Auger electron (RAE) spectrum have been perf
Heavy quarks are copiously produced in ultraperipheral heavy ion collisions. In the strong electromagnetic fields, c (c) over bar and b (b) over bar are produced by photonuclear and two-photon interactions. Hadroproduction can also occur in grazing interactions. We calculate the total cross sections and the quark transverse momentum and rapidity distributions, as well as the Q (Q) over bar invaria
