introduction: discharge of textile wastewater causes the reduction of sunlight penetration, interferes with the receiving waters ecology and damage the environment. the aim of this study was to determine the removal efficiency of reactive blue 19 dye from aqueous solutions by cuttlefish bone powder. materials & methods: this study was performed experimentally and in laboratory scale. in this re...

During year 2008–11, some infected leaves of eucalypt trees (Eucalyptus camaldulensis Dehnh.) having blight and spot symptoms were collected in Golestan province (N Iran). The necrotic spots were appeared on both surfaces of the leaves and were circular to irregular, single to confluent, medium brown to light brown with red brown margin (Fig. 1A & B). In some cases, young leaves have been sever...

BACKGROUND A growing body of research suggests that racial discrimination may affect the health of Black men and Black women differently. AIMS This study examined Black patients with diabetes mellitus (DM) in order to test gender differences in (1) levels of perceived racial discrimination in health care and (2) how perceived discrimination relates to glycemic control. METHODS A total of 16...

Central black hole masses for 118 spiral galaxies representing morphological stages S0/a through Sc and taken from the large spectroscopic survey of Ho et al. (1997) are derived using K s-band data from 2MASS. Black hole masses are found using a calibrated black-hole – K s bulge luminosity relation, while bulge lumi-nosities are measured by means of a two-dimensional bulge/disk decomposition ro...

Given a connected graph G = (V,E), two players take turns occupying vertices v ∈ V by putting black and white tokens so that the current vertex sets B,W ⊆ V are disjoint, B ∩W = ∅, and the corresponding induced subgraphs G[B] and G[W ] are connected any time. A player must pass whenever (s)he has no legal move. (Obviously, after this, the opponent will take all remaining vertices, since G is as...

The textile industry generates a large volume of chemically diversified effluents containing, among other compounds, dyes. Untreated wastes are contaminants to surface water, soil, and groundwater. In this aspect, various studies have explored the issue contamination alluvial soils in Alto Capibaribe region, northeast Brazil, due local activity. This inserted into Brazilian semiarid suffers fro...
