Background: We studied the impact of radical pericardiectomy on early and long-term patient survival, postoperative New York Heart Association (NYHA) functional class, and left ventricular ejection fraction in patients with chronic constrictive pericarditis compared to a sub-total pericardiectomy. Methods: From 1991 to 2016, 41 patients underwent pericardiectomy for chronic constrictive pericardit
The implementation of MIMO technology on compact mobile terminal devices poses a unique challenge for system designers. This is because it requires that multiple antennas be closely separated in a confined volume, which results in strong mutual coupling among the antennas and high spatial correlation for the signals. In this paper, we present a review on the latest developments of using uncoupled
Recent work on compact multiple antennas in a random environment is reviewed, including extensions of the energy density antenna and the MIMO cube. The performance of handsets with multiple antennas is dependent on many factors due to the close proximity of the antennas. The distribution of scatterers in the environment has an impact on the distributed directivity of the antennas, the powers absor
Conventionally, the spacing between adjacent elements in an antenna array are set at half-a-wavelength in order to obtain maximum spatial resolution while avoiding spurious sidelobes. However, for antenna arrays that are implemented in a compact manner, the spacing between the adjacent elements can be significantly less than half-a- wavelength. The small spacing between the antennas results in str
Recent theoretical and simulation studies reveal that closely coupled antennas with appropriately chosen impedance matching loads can yield desired characteristics of small antenna correlation coefficients and/or high received power levels. However, no experiment has been performed to verify these claims. Here, we describe an experimental setup used to investigate the correlation and received powe

It is generally known that gerunds can have a null subject (NS) that takes the preceding clause as its antecedent. Given certain restrictions independently argued for in the literature, the NS in question cannot be pro, neither can it be maintained that such gerunds have the status of relative clauses. Therefore, the subject in question must be analysed as PRO, which entails that the theoretical s

Raw milk may be a risk for public health if it is contaminated with zoonotic pathogens. To study the prevalencein unpasteurized milk from Swedish farms, bovine and small ruminant dairy farms were sampled. Since thesampling method and transport conditions may influence the outcome of analyses, efforts were made to optimizethe methodology. Culturing of bacteria was done from in-line milk filters col
AbstractThe value of infoming children about impending medical procedures was investigated, particularly in ægard to possible effects on anxiety, fear, noncooperation and distress in specific clinical situations: urological investigation, heart catheterization, lumbar puncture, acute appendectomy.

During the last few years, a more liberal use of premedication in children scheduled for Ürinary tract examinations was noted. In this retrospective study, the influence of the institution of psychological means for preparation as supplement or alternative to premedication on the incidence of cases receiving premedication was investigated. During the period from 1978 to 1982, this was followed in
A psychological preparation program was developed for use prior to emergency surgery in children. The purpose of this study was to test the hypothesis that provision of specific information prior to an emergency operation would reduce the need for premedication to control anxiety and stress. Children were randomly assigned to either a verbally prepared group given narcotic-sedative premedication (
AbstractThe cerebellum is an important part of the brain and in very preterm infants the cerebellum is smaller at term equivalent age compared to that of infants born at term.Hypothesis and aims: The general hypothesis is that preterm birth per se causes cerebellar underdevelopment and that certain events following preterm birth, either complications or treatments, can aggravate the underdevelopme
Draba incana L. (Brassicaceae) is an arctic-alpine species which is both common and widely distributed in Iceland. Voucher specimens of D. incana in the ICEL and AMNH herbaria were examined and no major changes in the taxonomic identification or the species distribution map were made. Living plants were collected in this study: nine from Eyjafjördur and Lake Mývatn, northern Iceland, and one from
The genus Draba L. is a conspicuous element of the arctic flora, comprising about 350 species worldwide which mostly are arctic-alpine polyploids. Previously, it has mainly been Draba incana L., D. norvegica Gunn., D. nivalis Liljebl., D. alpina L., D. fladnizensis Wulf., D. daurica DC., D. lactea and D. cinerea Adams that have been considered as belonging to the Icelandic flora. In this paper we
In Swedish historical archaeology, studies of towns have diverged from definition to deconstruction. In landscape studies the existence of occasional similar expressions of power in rural contexts as in towns is stressed. Another observation is that towns can display vague forms of urbanity, with lack of dense settlement and varied economy, as well as showing agrarian affiliations. A focus on sing
