-The relationships of the Wrentit (Chamaea fasciata) have been debated since its discovery in 1845. The titmice (Parus), babblers (Timaliini), Old World warblers (Sylviini), bushtits (Psaltriparus), wrens (Troglodytidae), and mockingbirds (Mimini) have been suggested as its closest relatives. Many authors have placed the Wrentit in a monotypic family, Chamaeidae. DNA-DNA hybridization compariso...

Not all the crude agglutinates are crushable into primary particles by beads-milling. The most reliable criterion for the crushability of crude detonation product is zeta-potential in aqueous suspension, which must be higher than +50mV or lower than -50mV as determined on a Zetasizer Nano-ZS (Malvern Instruments, England). We use fluffy, grey-coloured fine powder made by Guangzhou Panyu Guangda...

The increasing influence of Atlantic inflows in the Arctic Ocean recent decades has had a potential impact on regional biogeochemical cycles major and trace elements. warm salty water, entering Eurasian Basin through Norwegian Sea margin Barents Sea, affects particle transport, sink, phyto-, zooplankton community structure could have far-reaching consequences for marine ecosystems. This study d...

In order to gain further insights into early solar system aggregation processes, we carried out an experiment on board the International Space Station, which allowed us study behavior of dust particles exposed electric arc discharges under long-term microgravity. The led formation robust, elongated, fluffy aggregates, were studied by scanning electron microscopy, backscatter diffraction, and sy...

morning glory syndrome (mgs) is a rare congenital optic disc anomaly characterized by a funnel-shaped, excavated optic disc surrounded by chorioretinal pigmentary disturbance. the main ophthalomoscopic feature of the mgs is enlarged optic disc with a funnel shaped scleral defect; elevated peripapillary chorioretinal pigmentation; and pale fluffy tissue of glial hyperplasia overlying the optic d...

Recent observations suggest that the abundance of carbon in the interstellar medium is only ∼ 60% of its solar value, and that other heavy elements may be depleted by a similar amount. Furthermore, more than half of the interstellar carbon is observed to be in the gas in the form of C, leaving less than ∼ 40% of the solar carbon abundance available for the dust phase. These observations have cr...

Acetylation of histones is a key regulatory mechanism of gene expression in eukaryotes. GcnE is an acetyltransferase of Aspergillus nidulans involved in the acetylation of histone H3 at lysine 9 and lysine 14. Previous works have demonstrated that deletion of gcnE results in defects in primary and secondary metabolism. Here we unveil the role of GcnE in development and show that a ∆gcnE mutant ...

The distribution and quantitation of enteroviruses among water, suspended solids, and compact sediments in a polluted estuary are described. Samples were collected sequentially from water, suspended solids, fluffy sediments (uppermost layer of bottom sediments), and compact sediment. A total of 103 samples were examined of which 27 (26%) were positive for virus. Polioviruses were recovered most...
