Purpose: Capsular related complications may occur during and/or following cataract s”rPew. Methods: We used endocapsular PUMA rings (EPR) to prevent such complications in eyes with pre or peroperative zonular c’ehiscence, high myopic eyes and eyes witl: exfoliation syndrome which have weak zonoles. EPR can be implanted easily through the phaco-incision before aspiration of the cortex or just be...

Polycrystalline ammonium dithionate has been examined for its radiation response in the low dose range (<5Gy) using EPR technique. The SO(3)(-) radical ion was detected as a single EPR line with a peak-to-peak derivative width of ca. 0.44mT in irradiated samples and its intensity was found to vary linearly with dose. At equal and moderate settings of microwave power and modulation amplitude amm...

A miniaturised electrochemical cell design for Electron Paramagnetic Resonance (EPR) studies is reported. The cell incorporates a Loop Gap Resonator (LGR) for EPR investigation of electrochemically generated radicals in aqueous (and other large dielectric loss) samples and achieves accurate potential control for electrochemistry by using micro-wires as working electrodes. The electrochemical be...

We present temperature-dependent measurements of the EPR frequency shifts for Na, K, and Rb interacting with polarized He. K and Na frequency shifts were measured via comparison with Rb frequency shifts swell known at low temperaturesd in Na-RbHe and K-RbHe spin-exchange cells. The lowered Rb vapor pressure of these “hybrid” spin-exchange cells also allowed us to extend the measured temperature...

Electronic patient records (EPR) may contain highly confidential and personal medical information. It is therefore essential that medical data is properly protected and managed. Today, it is widely recognized that patients have a right to selfdetermination and to exert control of their own medical data by consent. In this paper, we present a cryptographic EPR access authorization scheme that in...

The inelastic neutron scattering (INS) and EPR transitions are considered for the spin-frustrated V3 and Cu3 nanomagnets. It is shown that the DM exchange and distortions determine the Q-dependence and redistribution of the intensities of the intraand inter-doublet INS transitions in the spin-frustrated 2(S=1/2) states as well as the intensities of the EPR transitions. The peculiarities of the ...

Electronic states of iron ion complexes in human blood from patients with melanoma have been investigated by electron paramagnetic resonance (EPR). The measurements were performed at liquid nitrogen temperature (77 K) on an X-band EPR spectrometer. Numerous types of iron paramagnetic centers have been identified. In several kinds of protein complexes exemplified by methemoglobin, transferrin or...

This paper investigates the effects of breaks in bonds, breaks in the earthing system and breaks in earth wire on the rise of the earth potential (EPR) in a substation and at the transmission tower bases using various models of an L6 tower. Different approaches were adopted to examine the integrity of the earthing system and the terminal towers. These effects were investigated to see the associ...
