Anion exchangeable layered mixed basic salt (LMBA) Ni1−xZn2x(OH)2(OCOCH3)2xnH2O thin film was deposited onto a glass slide substrate through the hydrothermal decomposition of mixed aqueous solution ...of zinc and nickel acetates. The molar ratio of Zn/Ni in mixed solution affected the orientation of LMBA crystals on the substrate. LMBA thin films obtained at 130°C in Zn rich solutions showedc-axis orientation perpendicular to the substrate surface. The acetate ions of oriented LMBA thin film easily exchanged with most of the inorganic, as well as the organic, anions without destruction of the thin film.
ABSTRACT--In February 2002, mass mortalities were first observed among striped catfish Pangasius hypophthalmus reared in freshwater ponds of central Sumatra, Indonesia. The affected fish showed pale ...gills, abdominal swelling and hemorrhage of the skin, as well as swelling of internal organs with white patches. Edwardsiella ictaluri was isolated from the internal organs of the diseased fish. The isolates showed pathogenicity to P. hypophthalmus by an artificial infection. However, the isolate preserved in a semisolid BHI agar for 6 months lost pathogenicity.
Vacuoles of radish (Raphanus sativus) contained a Ca
2+
-binding protein (RVCaB) of 43 kDa. We investigated the Ca
2+
-binding properties of the protein. RVCaB was expressed in Escherichia coli and ...was purified from an extract by ion-exchange chromatography, nitrocellulose membrane filtration, and gel-filtration column chromatography. Ca
2+
-binding properties of the recombinant protein were examined by equilibrium dialysis with
45
Ca
2+
and small dialysis buttons. The protein was estimated to bind 19Ca
2+
ions per molecule with a K
d
for Ca
2+
of 3.4 mM. Ca
2+
was bound to the protein even in the presence of high concentrations of Mg
2+
or K
+
. The results suggested that the protein bound Ca
2+
with high ion selectivity, high capacity, and low affinity.
This paper describes the measured results of the two-dimensional flux density distribution of a YBCO bulk under applied AC magnetic fields with various frequency. Melt-processed oxide superconductors ...have been developed in order to obtain strong pinning forces. Various electric mechanical systems or magnetic levitation systems use those superconductors. The major problem is that cracks occur because the bulk superconductors are brittle. The bulk may break in magnetizing process after cracks make superconducting state instable. The trapped flux density and the permanent current characteristics of bulk superconductors have been analyzed, so as to examine the magnetizing processes or superconducting states of the bulk. In those studies, the two-dimensional surface flux density distributions of the bulk in static fields are discussed. On the other hand, the distributions in dynamic fields are little discussed. We attempted to examine the states of the bulk in the dynamic fields, and made a unique experimental device which has movable sensors synchronized with AC applied fields. As a result, the two-dimensional distributions in the dynamic fields are acquired by recombining the one-dimensional distributions. The dynamic states of the flux of the bulk and the influences of directions of cracks are observed from the distributions. In addition, a new method for measuring two-dimensional flux density distribution under dynamic magnetic fields is suggested.

Ornamental and laboratory fish populations are part of the global trade and can spread pathogens around the world. Laboratory fish are widely used as model for biomedical research, which can be ...impacted by underestimated health conditions affecting the fish model. The global ornamental fish industry deals with a huge diversity of fish species. High mortality rate often causes significant losses, linked to polymicrobial infections facilitated by stressful conditions compromising host health, although accurate data on ornamental fish trade losses remain difficult to retrieve. Pet fish diseases can spread undetected between artificially recreated ecosystems, posing threats difficult to eradicate once established or when contaminating natural water systems. This 3-hour virtual workshop aimed at highlighting novel aspects of the pathobiology and diagnostics of infectious threats that could be spread through ornamental fishes and impact research using laboratory fish as biological models. In total, 108 participants from various countries all over the world joined this virtual workshop during the EAFP conference live streaming.
