Accurate Molar Mass Estimation of Polyolefin Blends Using High Temperature-size Exclusion Chromatography With Triple Detection: Insight Into Molecular Level Mixing of Polypropylene With Various Application Grades of Polyethylene.

In this study, a commercially available polypropylene homopolymer (H-PP) was blended with blow molding polyethylene (PE) grade via melt mixing using a compounding machine. The resulting blends were subjected to high-temperature size exclusion chromatography (SEC) analysis, coupled with infrared-5 (IR-5), viscometer (VISCO), and multi-angle laser light scattering (MALS) detectors. The molecular weight (MW) and MW distributions were investigated using SEC, and the exact blend compositions were evaluated using C nuclear magnetic resonance.

High temperature-size exclusion chromatography with triple detection to assess the molecular architecture of low-density polyethylene: Insight into branching and processability correlations.

In this study, three commercially available low-density polyethylene (LDPE) polymers produced via a tubular reactor process, with varying melt flow rates at 190°C/2.16 kg (4.0, 1.

Statistical Analysis on Impact of Image Preprocessing of CT Texture Patterns and Its CT Radiomic Feature Stability: A Phantom Study.

Aim: To examine computed tomography (CT) radiomic feature stability on various texture patterns during pre-processing utilizing the Credence Cartridge Radiomics (CCR) phantom textures.

Materials And Methods: Imaging Biomarker Explorer (IBEX) expansion for the abbreviation IBEX extracted 51 radiomic features of 4 categories from 11 textures image regions of interest (ROI) of the phantom. 19 software pre-processing algorithms processed each CCR phantom ROI.

Analysing the possibility of utilizing CBCT radiomics as an independent modality: a phantom study.

Aim: To verify if computed tomography (CT) radiomics were reproducible by cone beam CT (CBCT) radiomics by using Catphan® 504.

Materials And Methods: Catphan® 504 was imaged   using the default IGRT OBI  CBCT   imaging protocols and CT scanner. Seven known density image regions of the phantom were segmented and image feature was extracted by Imaging Biomarker Explorer (IBEX) software.

Design and Development of In-House Multichannel Applicator for HDR Vaginal Brachytherapy and Dosimetric Comparision with Single Channel Applicator.

Introduction: Endometrial cancer (EC) is a leading cause of female cancer in developed countries. The total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic lymph node dissection is the primary management of endometrial cancer. Afterwards vaginal brachytherapy can be preferred either alone or combined with external beam radiotherapy to avoid the vault recurrence.

Facial onset sensory motor neuronopathy: an immunoglobulin-responsive case.

Facial onset sensory motor neuronopathy (FOSMN) is a recently identified condition characterized initially by trigeminal sensory involvement followed by sensory propagation and motor neuronopathy. Few cases have been reported, and latest evidence points toward a neurodegenerative cause. We describe a 59-year-old female who presented a typical clinical picture of FOSMN over 10 years.

Facile and one pot synthesis of gold nanoparticles using tetraphenylborate and polyvinylpyrrolidone for selective colorimetric detection of mercury ions in aqueous medium.

In this work, we reported for the first time, a facile and one step synthesis of gold nanoparticles from HAuCl(4), employing tetraphenylborate as the reducing agent. The synthesis is not only facile but also yields "dumb-bell-shaped"particles. This shape appears to arise from a possible emulsion of the products of oxidation/decomposition of tetraphenylborate by HAuCl(4), surrounding the particle.
