Trichomonosis in a free-living Stock Dove (Columba oenas)

In October 2004, a free-living Stock Dove (Columba oenas) was found infected with Trichomonas spp. in the district of Soest, North Rhine- Westphalia, Germany. A huge buccal nodular lesion caused an occlusion of the esophagus and an external swelling. The bone of the mandibula was already softened and nearly solubilised. The microscopical examination of a wet swab sample from the carcass detected T

Modelling future soil chemistry at a highly polluted forest site at Istebna in Southern Poland using the "SAFE" model

The multi-layer dynamic model SAFE was applied to the forested catchment istebna (Southern Poland), to study recovery from acidification. Environmental pollution in the area has been historically high. The model uses data from an intensive monitoring plot established in 1999 in a spruce stand, which was planted in 1880. Observations showed that the soil was depleted of base cations. The measured b

Isomer Spectroscopy Using Relativistic Projectile Fragmentation at the N=Z Line for A~80-90

The preliminary results from the RISING Stopped Beam Isomer Campaign are presented, with specific focus on results of the initial experiment to investigate isomeric decays along the N=Z line around A similar to 80-90 following the projectile fragmentation of a Ag-107 primary beam at an energy of 750 MeV per nucleon. A description of the technical aspects behind the design of the RISING array is pr

Effects of ambient UV-radiation on the behaviour of mayfly larvae of the genus Deleatidium from trout bearing and fishless streams in New Zealand

New Zealand ground levels of UV-radiation have always been comparatively high, however, little attention has been paid to the effects of UV-radiation on biotic interactions in New Zealand freshwater systems. In two outdoor short term microcosm experiments we tested the effects of UV-radiation on the behaviour of grazing mayfly Deleatidium (Ephemeroptera) larvae. The relationship between pigmentati

Footwear for cold work: a field study at a harbour

A series of field studies at cold workplaces were initiated. This paper deals with a study at a harbour and the main attention is paid to the thermal responses of the feet and footwear performance. The study was carried out in February. Eight male workers were the subjects. They were selected among volunteers who carried out four different jobs in pairs. The warm winter boots were provided by the

A one step motion detection circuitry

A model of motion and direction detection is presented as well as results from a computer simulation of the model. The model is based on cooperative computations which allows an extremely simple architecture. Furthermore, it involves only one logical step in its computations even though Hubel and others have argued that motion detection requires at least two. This is made possible by not including

Significance and metabolism of complexed and noncomplexed prostate specific antigen forms, and human glandular kallikrein 2 in clinically localized prostate cancer before and after radical prostatectomy

PURPOSE: We studied plasma concentrations and elimination rates of prostate specific antigen (PSA) complexed to alpha1-antichymotrypsin and alpha2-macroglobulin, free PSA, total PSA (free PSA plus PSA alpha1-antichymotrypsin) and human glandular kallikrein 2 before, during and after radical retropubic prostatectomy for clinically localized prostate cancer. MATERIALS AND METHODS: Plasma was collect

Electrical and thermal characterization of a PV-CPC hybrids

Long term evaluation of an asymmetric CPC PV-thermal hybrid built for high latitudes, MaReCo (MaximumReflectorCollector), is performed in Lund, lat 55.7o, and this paper discusses output estimates and characteristics of the system. The output estimates are calculated using the MINSUN simulation program. To get the input for MINSUN, measurements were performed on two MaReCo prototypes. These measur

Technique for microwave-induced hyperthermia in superficial human tumours

In order to induce local hyperthermia in superficial tumours a computer system using a 2,450 MHz microwave generator connected to a circular (diameter 90 mm) direct contact applicator was constructed based on invasive temperature control. Small thermistor probes with a diameter of 0.6 mm are inserted in the tumour and surrounding tissues. Eight thermistors can be used simultaneously and one of the

Expression and characterization of deletion recombinants of two cGMP-inhibited cyclic nucleotide phosphodiesterases (PDE-3)

cDNAs encoding two PDE-3 or cyclic GMP-inhibited (cGI) cyclic nucleotide phosphodiesterase (PDE) isoforms, RPDE-3B (RcGIP1) and HPDE-3A (HcGIP2), were cloned from rat (R) adipose tissue and human (H) heart cDNA libraries. Deletion and N- and C-terminal truncation mutants were expressed in Escherichia coli in order to define their catalytic core. Active mutants of both RPDE-3B and HPDE-3A included

Variable Valve Actuation for Timing Control of a Homogeneous Charge Compression Ignition Engine

Autoignition of a homogeneous mixture is very sensitiveto operating conditions. Therefore fast combustion phasingcontrol is necessary for reliable operation. There areseveral means to control the combustion phasing of a Homogeneous Charge Compression Ignition (HCCI) engine.This paper presents cycle-to-cycle cylinder individual controlresults from a six-cylinder HCCI engine using a VariableValve Ac

Accelerator mass spectrometry

Accelerator mass spectrometry (AMS) is a world-wide spread technique and nearly 50 AMS laboratories exist today. The most widely spread application of AMS is for radiocarbon dating and an estimated total of nearly 100000 14C samples are measured per year. Other isotopes used are 10Be, 26Al, 36Cl, 41Ca, 129I. The number of these measured per year is estimated to be 10% of the number of 14C samples

ACTH revisited - potential implications for patients with renal disease

Adrenocorticotrophic hormone (ACTH) facilitates the synthesis of adrenal glucocorticoids by maintaining the enzymes that control the side-chain cleavage of cholesterol, the rate-limiting step in the biosynthesis of steroids 1]. Thus, ACTH is involved in the control of adrenal lipid metabolism. Recent studies have revealed that treatment with ACTH in pharmacological dosage also influences plasma li

A folding variant of human alpha-lactalbumin induces mitochondrial permeability transition in isolated mitochondria

A human milk fraction containing multimeric alpha-lactalbumin (MAL) is able to kill cells via apoptosis. MAL is a protein complex of a folding variant of alpha-lactalbumin and lipids. Previous results have shown that upon treatment of transformed cells, MAL localizes to the mitochondria and cytochrome c is released into the cytosol. This is followed by activation of the caspase cascade. In this st

Genetic probes of three theories of maternal adjustment: I. Recent evidence and a model

Studies focusing on genetic and social influences on maternal adjustment will illumine mother's marriage, parenting, and the development of psychopathology in her children. Recent behavioral genetic research suggests mechanisms by which genetic and social influences determine psychological development and adjustment. First, heritable, personal attributes may influence individuals' relationships wi
