Growth of ectomycorrhizal mycelia and composition of soil microbial communities in oak forest soils along a nitrogen deposition gradient

Deciduous forests may respond differently from coniferous forests to the anthropogenic deposition of nitrogen (N). Since fungi, especially ectomycorrhizal (EM) fungi, are known to be negatively affected by N deposition, the effects of N deposition on the soil microbial community, total fungal biomass and mycelial growth of EM fungi were studied in oak-dominated deciduous forests along a nitrogen d

Management of bile duct calculi : a study with special reference to long-term outcome

Popular Abstract in Swedish Mellan 15 och 20 % av de patienter som kommer för behandling av gallstenssjukdomen (stenar i gallblåsan) har samtidigt stenar i de djupa gallvägarna (förbindelsegången mellan lever-gallblåsa och tolvfingertarmen). Hos yngre patienter är andelen endast 7-8 %, medan den i äldre patientgrupper kan vara 50 % eller mer. Traditionellt har stenarna i gallgången avlägsnats samtOpen surgical versus endoscopic treatment of CBD stones in 80 elderly not cholecystectomized patients revealed a similar efficacy of stone clearance and early major complication rates, as well as total complication rates and hospitalization time in the two groups during 5 to 9 years follow-up. However, more patients in the endoscopically treated group died from heart disease, suggesting surgery to

Exploring the impacts of the tropical Pacific SST on the precipitation patterns over South America during ENSO periods

Summary Previous studies on precipitation over South America that strongly support the existence of links between precipitation and SST anomalies in the Pacific Ocean have identified specific regions where the ENSO signal is particularly stronger. Northeast of Brazil and some parts of southern South America are examples of these regions. However, the same attention was not taken to identify which

Time course of ECG depolarization and repolarization changes during ischemia in PTCA recordings

Objectives: In this work we studied the temporal evolution of changes in the electrocardiogram (ECG) as a consequence of the induced ischemia during prolonged coronary angioplasty, comparing the time course of indexes reflecting depolarization and those reflecting repolarization. Methods: We considered both local (measured at specific points of the ECG) and global (obtained from the Karhunen-Loeve

Miniaturized on-line digestion system for the sequential identification and characterization of protein analytes

A miniaturized on-column digestion system constructed for the sequential analysis of semi-purified protein analytes is presented. By utilizing fused silica capillary (diameter 150 mu m) packed with a zone of trypsin-modified Eupergit C beads and a second zone of reversed-phase C18 material, a linear column set-up was constructed. The protein analytes (pmol amounts) were first digested in the 600 n

Two-sided ideals in q-deformed Heisenberg algebras

In this article, the structure of two-sided ideals in the q-deformed Heisenberg algebras defined by the q-deformed Heisenberg canonical commutation relation AB-qBA=I is investigated. We show that these algebras are simple if and only if q = 1. For q not equal 1, 0 we present an infinite descending chain of non-trivial two-sided ideals, thus deducing by explicit construction that the q-deformed Hei

Is there seasonal variation in size and mass of Red Admirals Vanessa atalanta on Capri, Italy?

I present data on seasonal variation in wing length and mass of Red Admirals Vanessa atalanta captured on Capri, Italy, during spring and autumn. The Red Admiral is a migratory butterfly that migrates north throughout Europe each year and then heads back south in the autumn. During the winter they are mostly found in the northern Mediterranean area where they previously were thought to hibernate,

Is erythromycin therapy teratogenic in humans?

The possible teratogenic effect of erythromycin therapy, noted previously, was studied. Women who had taken erythromycin or penicillin V in early pregnancy and their infants were studied, using the Swedish Medical Birth Register where information on drug use during pregnancy was recorded based on interviews in early pregnancy. The risk for any congenital malformation after erythromycin therapy (bu

Attenuation and scatter correction in SPECT for sources in a nonhomogeneous object: a monte Carlo study

Single-photon emission computed tomography (SPECT) is important for imaging radioactivity distributions in vivo. Quantitative SPECT is limited due to attenuation and scatter contribution. Approximations such as constant attenuation and mono-exponential scatter functions will not be valid for non-homogeneous regions. A correction method is described where non-uniform density-maps are used in the at

Bone mineral density in athletes during and after career: a comparison between loaded and unloaded skeletal regions

Bone mineral density (BMD) was measured in the upper part of the skull, the femoral neck, and the total body by dual energy X-ray absorptiometry in 56 male and 33 female active athletes, 18-40 years of age, together with 64 male ex-weight lifters, 35-79 years of age. The active athletes were compared with 41 male and 54 female controls, the ex-weight lifters with 133 male controls. The purpose of

The Ancient Synagogue from Its Origins until 200 C.E. : Papers Presented at an International Conference at Lund University October 14-17

This conference volume is structured by the five research areas of the Lund syna-gogue project “The Ancient Synagogue: Birthplace of Two World Religions,” funded by The Bank of Sweden Tercentenary Foundations, and by its time limit up to ca 200 C.E. The aim of the conference was to give an opportunity for young, emerging scholars to interact with some of the most prominent and established scholars

Buda-Lund hydro model for ellipsoidally symmetric fireballs and the elliptic flow at RHIC

The ellipsoidally symmetric extension of Buda-Lund hydrodynamic model is shown here to yield a natural description of the pseudorapidity dependence of the elliptic flow upsilon(2)(eta)), as determined recently by the PHOBOS experiment for Au + Au collisions at root(S)NN = 130 and 200 GeV. With the same set of parameters, the Buda-Lund model describes also the transverse momentum dependence of upsi

Interaction between microclimate and concrete--a prerequisite for deterioration

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
