The hydrogen storage performance of reactive hydride composite Mg ( NH 2 ) + LiH can be significantly improved by the addition LiBH 4 and subsequent formation an amide–borohydride compound Li BH 3 during release. Herein, investigation into structure anion motions using synchrotron radiation powder X-ray diffraction (SR-PXD; 295–573 K) quasielastic neutron scattering (QENS; 297–514 is described....

BACKGROUND Fractalkine (FKN) is involved in the occurrence and development of human lupus nephritis. It is known to be upregulated by lipopolysaccharide (LPS) as a stimulus in vivo. MRL/lpr mice have been used as an in vivo model to study lupus nephritis. Methylprednisolone (MP) is used widely in the clinical treatment of progressive glomerular diseases such as lupus nephritis. The aim of this ...

Nanoparticles of iron oxide (Fe3O4) were obtained by Coprecipitation with synthesis time of 30, 60 and 90 min. The morphology of the samples was investigated by scanning electron microscopy (SEM) and structural characteristics were obtained by X-ray diffraction (XRD). The crystallite size was calculated from the spectrum X-ray diffraction with the application of the Scherrer equation and Winfit...

We develop a model that explores the link between services and fragmentation. In our model components used in the manufacturing process are made with services and labor. Low foreign wages create an incentive to outsource component production (fragmentation). However, the importance of services in the manufacturing process can play a role in limiting fragmentation. Although advanced economies ha...

In countries with secure property rights, corporate transparency improves investment efficiency and increases growth by alleviating information asymmetry. However, in countries with insecure property rights, greater transparency can increase the risk of government expropriation. Therefore, some firms that would benefit most from transparency cannot take full advantage of it, as they set sub-opt...

Previously we demonstrated that peroxisomicine A1 (T-514), a plant toxin isolated from Karwinskia species, has a deteriorating effect on the integrity of peroxisomes of methylotrophic yeasts. Here we describe two strains of Hansenula polymorpha, affected in the normal utilization of methanol as sole source of carbon and energy due to peroxisomicine A1 treatment. The two strains isolated (L17 an...
