On the importance of hysteresis and heterogeneity in the numerical simulation of unsaturated flow

Soil hydraulic properties in field scale porous media are distributed with large spatial heterogeneity. Thus, detailed understanding of micro-physical properties leading to macro-scale heterogeneity is important for generalizing purposes in modeling. Hysteretic water retention properties greatly affect solute transport under unsaturated condition. In this study, laboratory infiltration experiments

RIFM fragrance ingredient safety assessment, α-Ionone, CAS Registry Number 127-41-3.

The use of this material under current use conditions is supported by the existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, as well as, environmental safety. Repeated dose toxicity was determined to have the most conservative systemic exp

The challenge of achieving target drug concentrations in clinical trials: experience from the Symphony study.

BACKGROUND: The Symphony study compared four immunosuppressant regimens, defined by protocol-specified target drug concentrations. This subanalysis examines actual drug levels and the implications on the interpretation of results. METHODS: De novo renal transplant patients (n=1645) were randomized to receive mycophenolate mofetil (2 g/day) and corticosteroids in combination with standard-dose cycl

Computed tomography measurements of different dimensions of maxillary and frontal sinuses.

We have previously proposed the use of Doppler ultrasound to non-invasively stage sinus infection, as we showed that acoustic streaming could be generated in nonpurulent sinus secretions and helped to distinguish it from mucopurulent sinus secretions. In order to continue this development of a clinically applicable Doppler equipment, we need to determine different dimensions of the paranasal sinus

Uniting Against Autocrats : Opposition Coordination, Turnovers and Democratization by Elections

As counter intuitive as it might sound, autocracy without elections is a rare combination today. Elections do not constitute democracy, but they can promote democratization. This dissertation studies the process of democratization through elections, focusing on the effect of opposition coordination. Several authors have stressed the importance of opposition coordination as an explanation for democ

Chip for wideband digital predistortion RF power amplifier linearisation

The authors present a custom chip for use in digital predistortion linearisation of RF power amplifiers. The chip is mainly implemented with systolic arrays. At maximum clock-rate, 130 MHz, the throughput is 16 Msamples/s with a 5 V supply voltage and power consumption of 1 W. A throughput of 2 Msamples/s is achieved at a 1.2 V supply voltage with 6 mW power consumption

Circulating biomarkers for prostate cancer

Due to its significant applicability for early detection, risk prediction and follow-up evaluation, prostate specific antigen (PSA) has revolutionized our ability to treat prostate cancer patients. With the prevalent use of PSA for early detection during the last two decades, disease characteristics have been altered towards early detected, localized tumors with a high chance of cure following loc

The POU5F1P1 pseudogene encodes a putative protein similar to POU5F1 isoform 1.

POU5F1, which encodes a transcriptional factor, has two alternatively spliced transcripts, 1 and 2, as well as six pseudogenes. Transcript 1 is considered to be a key regulator of cellular pluripotency and self-renewal. The POU5F1 pseudogene, POU5F1P1 on 8q24, encodes a protein with 95% homology with the isoform 1 of POU5F1. It is located 15 kbp downstream of the SNP rs6983267, which is strongly a
