The diabetes-prone BioBreeding (BB) and Komeda diabetes-prone (KDP) rats are both spontaneous animal models of human autoimmune, T-cell-associated type 1 diabetes. Both resemble the human disease, and consequently, susceptibility genes for diabetes found in these two strains can be considered as potential candidate genes in humans. Recently, a frameshift deletion in Ian4, a member of the immune...

In this work, the application of the X-ray multiple diffraction technique using synchrotron radiation at Laboratório Nacional de Luz Síncrotron (LNLS) to study KDP phase transition induced by electric field is discussed. A Huber three-axis (ω, φ, 2θ) diffractometer mounted on a table which rotates around the incident beam allows to measure Renninger scans (RS) at the XRD station of LNLS using t...

In this study micro-sensors were employed to analyse macro-kinematic parameters during a classical cross-country skiing competition (10 km, 2-lap). Data were collected from eight male participants during the Australian championship competition wearing a single micro-sensor unit (MinimaxX™, S4) positioned on their upper back. Algorithms and visual classification were used to identify skiing sub-...

For a number of applications it is desirable to frequency double the output from high-power mode-locked ruby and neodymium lasers. Second harmonic generation (SHG) in LiNb03 and KHaPO. (KDP) crystals from picosecond light pulses emitted by a Nd3+:glass laser has previously been studied theoretically and experimentally. 1-3 This letter deSCribes details of an efficient intracavity second harmoni...

SUMMARK Attenuation by heavy rain is a major operational problem in radar estimation of rainfall rates, and one which is increasingly severe at wavelengths shorter than 10 cm. Gate-by-gate correction algorithms, including those using both reflectivity ( Z H ) and differential reflectivity ( Z D R ) , are inherently unstable. In addition values of ZH and ZDK arc affected by hail, which causes li...

Polarimetric radar measurements at C-band require correction for propagation effects before using them for rainfall retrieval. Since differential phase shift Kdp is affected by the spatial variation of the backscattering differential phase shift δ, a new neural-network estimation technique is applied to remove δ effects on Kdp estimate. In this study we also explore a new hybrid iterative techn...

The local atomic structure of habit-modifying transition metal cations within the crystal lattice of potassium dihydrogen phosphate (KDP) is investigated using X-ray absorption spectroscopy (XAS) and X-ray standing wave (XSW) spectroscopy, together with molecular modeling. XAS reveals the transition metal cations to be structurally incorporated into the crystal lattice as an ionic complex that ...
