Photon energy dependent intensity variations are experimentally observed in the L2,3M2,3M2,3 Auger spectra of argon clusters. Two cluster sizes are examined in the present study. Extrinsic scattering effects, both elastic and inelastic, involving the photoelectron are discussed and suggested as the explanation of the variations in the Auger signal. The atoms in the first few coordination shells su
Amperometric screen-printed biosensor arrays for detection of pesticides (organophosphates and carbamates) and phenols have been developed. Cholinesterases (AChE and BChE), tyrosinase (TYR), peroxidases (SBP. soybean and HRP. horseradish) and cellobiose dehydrogenase (CDH) were combined on the same array consisting of one Ag/AgCl reference electrode surrounded by eight radially distributed working
OBJECTIVE: Neuropeptide Y is a co-transmitter with noradrenaline in sympathetic neurons supplying arteries and veins with potent contractile effects. To investigate the role of neuropeptide Y in hypertension, we measured the circulating levels of neuropeptide Y and noradrenaline in patients with severe hypertension. DESIGN: Samples were collected from patients with untreated, severe hypertension (
This article presents reasons for undertaking "The Comparative Study of the Prevention of Crime and Violence by Mentally Ill Persons" and reasons for decisions regarding the study design and choice of measures. A brief portrait of the forensic patients that have been recruited is also presented. Community treatment programs could offer long-term cost-effective care for offenders with major mental
The aims of this study were to investigate if low-frequency fatigue (LFF) dependent on the duration of repeated muscle contractions and to compare LFF in voluntary and electrically induced exercise. Male subjects performed three 9-min periods of repeated isometric knee extensions at 40% maximal voluntary contraction with contraction plus relaxation periods of 30 plus 60 s, 15 plus 30 s and 5 plus
Antimicrobial peptides (AMP) are effector molecules of the innate immune system. A cross-functionality exists between AMPs and heparin-binding peptides. Here, we show that the peptides QPTRRPRPGTGPGRRPRPRPR-P (QPT22), derived from proline arginine-rich end leucine-rich repeat protein (PRELP) and KRFKQDGGWSHWSPWSS (KRF17) from thrombospondin exert antimicrobial activities against the Gram-negative
Aims Many patients with sinus node disease or atrioventricular block have previously received pacemakers with only ventricular stimulation (VVI or VVIR). This study aimed to investigate whether quality of life and cardiac function were affected by an upgrade to dual chamber pacing (DDDR or DDIR) following long-term ventricular stimulation. Methods After implantation of an atrial lead and a DDDR pu
The automotive industry is using more and more of Advanced High Strength Steel in order to reduce the weight of the car. Since this will generate more springback, it is of vital importance to be able to predict the amount of springback in the parts. Otherwise, many late changes have to be made in order to fit the parts in their position. In order to increase the ability to understand and test the
Specific inactivation of TGFbeta signaling in neural crest stem cells (NCSCs) results in cardiovascular defects and thymic, parathyroid, and craniofacial anomalies. All these malformations characterize DiGeorge syndrome, the most common microdeletion syndrome in humans. Consistent with a role of TGFbeta in promoting non-neural lineages in NCSCs, mutant neural crest cells migrate into the pharyngea
A new control strategy using feedback control has been developed for the multi-cylinder paper dryer configuration to reduce moisture transients in the drying section. The air system in the blow boxes was used to control the fast moisture transients in the paper machine. The new control system was combined with a previously developed physical model and was then compared with a conventional moisture
This paper presents a unified approach to multiscale detection of transient evoked otoacoustic emissions (TEOAEs). Using statistical detection theory, it is shown that the optimal detector involves a time windowing operation where the window can be estimated from ensemble correlation information. The detector performs adaptive splitting of the signal into different frequency bands using either wav
A study of the Slavonic translations of a Byzantine Greek world chronicle of the 10th c. AD. My study defines the importance of the Slavonic text for a student of the Greek text.
Background: In a sample of patients in clinical occupational medicine we have demonstrated that an upper limb neurological examination can reliably identify patterns of findings suggesting upper limb focal neuropathies. This further study aimed at approaching the diagnostic accuracy of the examination. Methods: 82 limbs were semi-quantitatively assessed by two blinded examiners ( strength in 14 in
We have tested the applicability of optically stimulated luminescence (OSL) to the dating of young estuarine sediments (< 1000 years) to determine whether this method can be used to complement and support existing techniques, such as Pb-210 dating. The degree of bleaching before deposition is investigated by examining the age trend in various sediment cores, and where possible, by comparison with
