Measurements of DSC, NMR and high-frequency spectroscopy have been done on PEO-H2O and PEO-H2O-HQ mixed systems. DSC measurements show that water molecules contained in PEO are divided roughly into two species: freezable water and non-freezable water. By 1H-NMR measurements, PEO and H2O protons show an absorption peak around 3.6 ppm and 4.5 ppm, respectively. All the PEO-H2O samples containing ...

Dynamic susceptibility contrast (DSC) perfusion-weighted imaging (PWI) is widely used in clinical settings for the radiological diagnosis of brain tumor. The signal change in brain tissue in gradient echo-based DSC PWI is much higher than in spin echo-based DSC PWI. Due to its exquisite sensitivity, gradient echo-based sequence is the preferred method for imaging of all tumors except those near...

This documents describes DSC benchmarking experiments using cycle 2A data. We investigated classification algorithms based on boosting, neural networks, mixture clustering and radial basis function networks. Two different magnitudes were used (17 and 20). Moreover classification was done with astrometry as well as without. Gaia DPAC: CU8-DU-MPIA DSC Benchmarking GAIA-C8-TN-MPIA-CE-001-01

hemicellulose of southern yellow pine wood spices was extracted by pressurized hot water at three different temperatures: 140°c, 155°c and 170°c. compounding with pp (polypropylene) was performed by extrusion after preparing wood flour and sieving to determine its mesh size. the ratio of wood to polymer was 50:50 based on oven-dry weight of wood flour. all extraction treatments and control samp...

Spatial correlation between densely deployed sensor nodes in a wireless sensor network (WSN) can be exploited to reduce the power consumption through a proper source coding mechanism such as distributed source coding (DSC). In this paper, we propose the Decoding Delay-based Distributed Source Coding (D-DSC) to improve the energy efficiency of the classical DSC by employing the decoding delay co...

Introduction: DSC perfusion studies are routinely performed for the assessment of stroke and brain tumor patients and are being used with increasing frequency in large scale clinical trials. A persistent DSC problem in routine imaging and clinical trials is that DSC CBF images are difficult to scale with accuracy. Although CBF images derived from DSC are (in principle) quantitative, the absolut...

Absb.ad-Industry acceptance of TINA (Telecommunications Information Networking Architecture) will depend heavily on both the evaluation of working systems that implement this architecture, and on the experiences obtained during the design and implementation of these systems. During the MESH' (Multimedia services on the Electronic Super Highway) project, a TINA based platform for networked multi...

The purpose of the present study was to present a multi-delay multi-parametric pseudo-continuous arterial spin labeling (pCASL) protocol with background suppressed 3D GRASE (gradient and spin echo) readout for perfusion imaging in acute ischemic stroke. PCASL data at 4 post-labeling delay times (PLD = 1.5, 2, 2.5, 3 s) were acquired within 4.5 min in 24 patients (mean age 79.7 ± 11.4 years; 11 ...

A study was conducted to detect and quantify lard stearin (LS) content in canola oil (CaO) using differential scanning calorimetry (DSC). Authentic samples of CaO were obtained from a reliable supplier and the adulterant LS were obtained through a fractional crystallization procedure as reported previously. Pure CaO samples spiked with LS in levels ranging from 5 to 15% (w/w) were analyzed usin...
