background: heavy metal pollution in the sediment of the yellow river draws wide attention in the recent years. the yellow river wetland nature reserve of zhengzhou is one of the major wetlands of the river and located at the beginning of the lower reach. in this article, we aimed to investigate the degree and the sources of the metal pollution in the reserve. methods: metals as cu, pb, cr, cd ...

HIGHLIGHTS Peanut shell waste is an alternative adsorbent for the removal dyes. Ultrastructural visualization of peanut fiber structure shell, multi-layers and many linkages among fibers which could create to various pores with different sizes. The best eosin Y percentage had 87.7% in 25 g L-1 at 30 minute.

Eosin Y, a long known dye molecule, has recently been widely applied as a photoredox catalyst in organic synthesis. Low cost and good availability make eosin Y an attractive alternative to typical inorganic transition metal photocatalysts. We summarize the key photophysical properties of the dye and the recent synthetic applications in photoredox catalysis.

BACKGROUND The laboratory diagnosis of hereditary spherocytosis commonly relies on NaCl-based or glycerol-based red cell osmotic fragility tests; more recently, an assay directly targeting the hereditary spherocytosis molecular defect (eosin-5'-maleimide-binding test) has been proposed. None of the available tests identifies all cases of hereditary spherocytosis. DESIGN AND METHODS We compare...

The genotypic variation on physico-chemical characteristics of wild grown plums (Prunus spinosa L.) was investigated. The total phenolic contents were in a range of 117 to 407 mg GAE/100 g FW. The vitamin C was highest in yellow colored fruits (12.10 mg/100 ml). The total soluble solid content varied between 9.40% (yellow colored) and 12.90% (dark purple colored) fruits.  Antioxidant activity o...

1. The yellow fever now in South America, the present yellow fever of Africa and the historic yellow fever of Panama and other American countries are the same disease. This conclusion is based on cross immunity tests in monkeys with strains of yellow fever virus from Africa and Brazil and on tests of sera from 25 persons, who had recovered from yellow fever in various places and at various time...
