Non-Absorbable Disaccharides for Hepatic Encephalopathy: A Systematic Review and Meta-Analysis.
- Gluud, LL; Vilstrup, H; Morgan, MY
Non-absorbable disaccharides (NADs) have been used to treat hepatic encephalopathy (HE) since 1966. However, a Cochrane review, published in 2004, found insufficient evidence to recommend their use in this context. This updated systematic review evaluates the effects of the NADs, lactulose and lactitol, for the treatment and prevention of HE in patients with cirrhosis. Thirty-eight randomized controlled trials (RCTs), involving 1828 patients, were identified via electronic and manual searches; 31 RCTs looked at the treatment of HE while seven looked at its primary/secondary prevention. Random-effects meta-analyses showed that, compared to placebo/no intervention, NADs had a beneficial effect on HE (relative...

METHODS: An electronic search of PsycINFO and PubMed was conducted, from inception to December 2011 using a combination of key words that included quality of life and dementia. RESULTS: Fifteen dementia-specific HRQL instruments were identified. Instruments varied depending on...
Computational Study of Glucosepane-Water Hydrogen-Bond Formation: an Electron Topology and Orbital Analysis.
- Nash, A; Saßmannshausen, J; Bozec, L; Birch, HL; de Leeuw, NH
The collagen protein provides tensile strength to the extra-cellular matrix in addition to localising cells, proteins and protein cofactors. Collagen is susceptible to a build up of glycation modifications as a result of an exceptionally long half-life. Glucosepane is a collagen crosslinking advanced glycation end product; the structural and mechanical effects of glucosepane are still the subjects of much debate. With the prospect of an ageing population, the management and treatment of age-related diseases is becoming a pressing concern. One area of interest is the isolation of hydrated glucosepane, which has yet to be reported at an atomistic level. This...

INVESTIGATION OF OSCILLATORY SOLUTIONS OF DIFFERENTIAL-DIFFERENCE EQUATIONS OF SECOND ORDER IN A CRITICAL CASE
- E. P. Kubyshkin; A. R. Moryakova
We consider a differential-difference equation of second order of delay type, containing the delay of the function and its derivatives. Such equations occur in the modeling of electronic devices. The nature of the loss of the zero solution stability is studied. The possibility of stability loss related to the passing of two pairs of purely imaginary roots, that are in resonance 1:3, through an imaginary axis is shown. In this case bifurcating oscillatory solutions are studied. It is noted the existence of a chaotic attractor for which Lyapunov exponents and Lyapunov dimension are calculated. As an investigation techniques we use...

Generación automática de la configuración de subestaciones eléctricas según el estándar IEC 61850 a partir de una herramienta de diseño gráfico
- Arribas López, Marcos
La evolución de las redes eléctricas se dirige hacia lo que se conoce como “Smart Grids” o “Redes Eléctricas Inteligentes”. Estas “Smart Grids” se componen de subestaciones eléctricas, que a su vez se componen de unos dispositivos llamados IEDs (Dispositivos Electrónicos Inteligentes – Intelligent Electronic Devices). El diseño de IEDs se encuentra definido en la norma IEC 61850, que especifica además un Lenguaje de Configuración de Subestaciones (Substation Configuration Language SCL) para la definición de la configuración de subestaciones y sus IEDs. Hoy en día, este estándar internacional no sólo se utiliza para diseñar correctamente IEDs y asegurar su interoperabilidad,...

- McDermott, Sean
Around the world today, the utilization of fossil fuels to provide humankind with the requisite magnitude of energy to maintain a technologically advanced society is becoming antiquated. Renewable processes that do not contribute to the alteration of the climate can help to ensure that Earth will remain recognizable for generations to come. Photons from the sun represent an excellent starting point due to the endless, free supply available in most places of the world. An obstacle that inhibits the transition to greater solar energy use is the need for more reliable, efficient, and inexpensive photon harvesting systems to be discovered...
Photo-induced halide redistribution in organic-inorganic perovskite films
- deQuilettes, Dane; Zhang, Wei; Burlakov, Victor; Graham, Daniel; Leijtens, Tomas; Osherov, Anna; Bulović, Vladimir; Snaith, Henry; Ginger, David; Stranks, Samuel
Organic-inorganic perovskites such as CH3NH3PbI3 are promising materials for a variety of optoelectronic applications, with certified power conversion efficiencies in solar cells already exceeding 21%. Nevertheless, state-of-the-art films still contain performance-limiting non-radiative recombination sites and exhibit a range of complex dynamic phenomena under illumination that remain poorly understood. Here, we use a unique combination of confocal photoluminescence (PL) microscopy and chemical imaging to correlate the local changes in photophysics with composition in CH3NH3PbI3 films under illumination. We demonstrate that the photo-induced “brightening” of the perovskite PL can be attributed to an order-of-magnitude reduction in trap state density. By imaging the...

- Anjos, O.
The spectroscopy is a technique that provides information about the
molecular structure of a substance. This technique is presently widely used
in pharmaceuticals, food, medical, textile applications, among others due to
the use of samples without manipulation.
Spectroscopy studies interaction between electromagnetic radiation with matter,
by determining the energy levels of atoms and molecules. The total energy of
a molecule is the sum of the electronic, vibrational and rotational energy.
The infrared spectroscopy and Raman spectroscopy are two techniques
used for faster identification, they are easy to use, requiring a little amount
of samples as well as providing information about the sample composition.
Two case studies related to application of...

Efficient and accurate approach to modeling the microstructure and defect properties of LaCoO3
- Buckeridge, J; Taylor, FH; Catlow, CRA
Complex perovskite oxides are promising materials for cathode layers in solid oxide fuel cells. Such materials have intricate electronic, magnetic, and crystalline structures that prove challenging to model accurately. We analyze a wide range of standard density functional theory approaches to modeling a highly promising system, the perovskite LaCoO3, focusing on optimizing the Hubbard U parameter to treat the self-interaction of the B-site cation's d states, in order to determine the most appropriate method to study defect formation and the effect of spin on local structure. By calculating structural and electronic properties for different magnetic states we determine that U=4...
