In this study we have synthesized a high surface area magnetic graphene oxide (MGO) impregnated with α-Fe2O3 for the removal of a toxic textile azodye Eriochrome Black T (EBT). MGO was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive analysis of X-rays (EDAX), fourier transform Infrared spectroscopy (FTIR), X-ray diffraction (XRD), Raman, Superconducting quantum interference device (SQUID) and Brunauer-Emmet-Teller (BET) surface area analyzer. Batch adsorption of EBT with MGO was studied using various isotherms and it was found to follow Langmuir monolayer...

X-ray photon correlation spectroscopy (XPCS), an extension of dynamic light scattering (DLS) in the X-ray regime, detects temporal intensity fluctuations of coherent speckles and provides scattering-vector-dependent sample dynamics at length scales smaller than DLS. The penetrating power of X-rays enables XPCS to probe the dynamics in a broad array of materials, including polymers, glasses and metal alloys, where attempts to describe the dynamics with a simple exponential fit usually fail. In these cases, the prevailing XPCS data analysis approach employs stretched or compressed exponential decay functions (Kohlrausch func...

Philips has launched a brand new true spectral CT scanner, the IQon Elite Spectral CT. Spectral CT provides a more nuanced look at body tissues, which reveals some information about the composition of anatomy and not only its structure. The different frequencies of X-rays in a spectral CT can be compared to different colors of light, which are produced by different frequencies of visible radiation. In a spectral CT, things like iodine show up at lower energies, while the visual impact of metal can be reduced when viewing the higher energy data. The new device, developed in a partnership with radiologists at Hadassah Hebre...

CONCLUSIONS: Radiological glenohumeral OA was more common in patients with DM1 than in controls for mild, but not moderate and severe OA. The radiological findings were not associated with shoulder pain or long-term glycaemic burden. PMID: 29239667 [PubMed - as supplied by publisher]

FLASH, the X-ray free-electron laser in Hamburg, Germany, employs a narrowband high-field accelerator THz source for unique THz pump X-ray probe experiments. However, the large difference in optical paths of the THz and X-ray beamlines prevents utilization of the machine's full potential (e.g. extreme pulse energies in the soft X-ray range). To solve this issue, lasing of double electron bunches, separated by 28 periods of the driving radiofrequency (at 1.3   GHz), timed for the temporal overlap of THz and X-ray pulses at the experimental station has been employed. In order to optimize conditions for a typical THz pump X...

Our daughter Makayla was born perfectly healthy on April 5th, 2014, passing all of the usual newborn screenings without issue. From day one, her personality shone through. She was strong-willed and had a smile that would light up her eyes before her mouth even showed a hint of joy. But over the next 3 months, Makayla wasn’t eating well and wasn’t gaining enough weight.  Our pediatrician referred us to Dr. Elizabeth Hait, a gastroenterologist at Boston Children’s Hospital. Dr. Hait would change Makayla’s formula multiple times and put her on medication for her acid reflux. Her pediatrician also ...

Authors: Malherbe GF, Navsaria PH, Nicol AJ, Edu S, Chowdhury S Abstract BACKGROUND: The purpose of this study was to determine whether patients with left-sided thoracoabdominal (TA) stab wounds can be safely treated with clinical and chest X-ray follow up. METHOD: A prospective, randomized control study was conducted at Groote Schuur Hospital from September 2009 through to November 2014. Patients with asymptomatic left TA stab wounds included in the trial were randomized into two groups. Group A underwent diagnostic laparoscopy and Group B underwent clinical and radiological follow-up. RESULTS: Twenty-seve...
