A formalism for the calculations of electron transport in multiterminal quantum systems is presented. The systems are described by tight-binding Hamiltonians. It is shown that by exploiting real-space Green's functions, a problem of the electron transport in a multiterminal system can be reformulated into a problem of the electron transport in an effective two-terminal system and can then be treat
A resistivity and time-domain induced polarization (IP) survey was conducted at a landfill Site under restoration at Harlov in Southern Sweden. The covering of the landfill had begun some years ago, without keeping precise records of the work done, as is usual in such procedures. The survey was conducted in two steps, on two adjacent areas. First, a number of geoelectrical sections were made on a
Abstract Introduction Carpal tunnel syndrome (CTS) is thought to be due to compression of the median nerve in the carpal tunnel. It is known that carpal tunnel pressures are elevated in wrist postures of flexion and extension and in those patients with CTS. Classic symptoms of CTS include night waking with pain, tingling, and numbness. These classic symptoms stimulated our interest in the relation
BACKGROUND/AIMS: Endoscopic sphincterotomy is an established treatment of retained or recurrent common bile duct calculi after cholecystectomy and in the majority of patients with an intact gallbladder. In order to identify patients ultimately requiring additional endoscopic procedures or surgery, factors predictive of decreased endoscopic bile duct clearance were sought. MATERIAL AND METHODS: Bet
A series of samples of vanadia supported on monoclinic zirconia were prepared with nominal loadings from a half up to sixteen theoretical vanadia layers. The samples were characterized with X-ray diffraction, scanning electron microscopy combined with energy dispersive X-ray analysis, high-resolution electron microscopy, Raman and diffuse reflectance infrared spectroscopy, and were used in the oxi
OBJECTIVE: To evaluate the effects of the three commercially available colloid solutions, 6% dextran 70, 6% hydroxyethyl starch (HES) 200/0.5, and 3.5% urea-linked gelatin on permeability for human albumin in a skeletal muscle in vivo model by evaluating their effects on the reflection coefficient for albumin. DESIGN: Controlled laboratory study. SETTING: University research laboratory. SUBJECTS:
Naturally grown fruit-bodies of Suillus luteus, S. bovinus and S. variegatus were subjected to Py-GC. The pyrograms obtained were statistically analysed and classified with a multivariate classification program (SIMCA). The class describing the S. bovinus pyrograms was significantly separated from both the S. luteus and the S. variegatus classes, while these two classes showed some over-lapping wh
I Sverige finns sedan flera år riktlinjer för hur förhöjda blodfetter bör behandlas hos patienter med kranskärlssjukdom. Generellt är intresset för och kunskapen om lipidbehandling stort inom den svenska läkarkåren. Trots detta nås uppsatta mål för behandling av blodfetter hos endast en minoritet av patienterna, och hälften av dem får inte någon farmakologisk lipidsänkande behandling, enligt en ny
Cellulases hydrolysing the interior parts of cellulose, also called endoglucanases, were immobilised in micro-immobilised enzyme reactors (RIMER) made of porous silicon with the purpose of investigating the use of such mu IMERs for hydrolysis of cellodextrins and soluble cellulose derivatives. The endoglucanases Trichoderma reesei Cel 12A (TrCel 12A) and Bacillus agaradhaerens Cel 5A (BaCel 5A) we
Background: In most clubfoot studies, the outcome instruments used are designed to evaluate classification or long-term cross-sectional results. Variables deal mainly with factors on body function/structure level. Wide scorings intervals and total sum scores increase the risk that important changes and information are not detected. Studies of the reliability, validity and responsiveness of these i
A fluorescence lidar measurement has been performed on the castle Övedskloster in Sweden. A mobile system from the Lund University was placed at ~40 m distance from the sandstone façade. The lidar system, which uses a frequency-tripled Nd:YAG laser with a 355-nm pulsed beam, induces fluorescence in each target point. Areas were studied by using whisk-broom scans. The possibility of detecting biode
High-spin terminating bands in heavy nuclei were first identified in nuclei around Er-158(90). While examples of special terminating states have been identified in a number of erbium isotopes, almost nothing is known about the states lying beyond band termination. In the present work the high-spin structure of Er-157 has been studied using the Gammasphere spectrometer. The subject of triaxial supe
