Background and Aim: Reactive dyes have extensively been used in textile industries during last year's due to their superior performance, but the effluence of the waste containing such dyes into water resources can pose hazardous effects on the environment and to the human health because of their carcinogenic, mutagenic, allergenic and toxic nature. The present research was performed to study th...

Background and purpose: Adsorption processes are widely used in removing pollutants from waste waters, particularly those that are not easily biodegradable such as dyes. In this study natural zeolite, which is easily found in many places, was used as a low-cost adsorbent for removal of dye from effluents. Materials and methods: Adsorption of Azo dyes including two basic and one reactive (React...

Seaweeds can produce variety of bioactive components for the benefits of humans. Malaysia is one of the countries to produce red seaweeds, which are popular secondary metabolites. Kappaphycus species, largest tropical red algae exhibit the high growth rate. It was reported that its biomass can grow double in just 15 to 30 days. Therefore, this investigation emphasized on two extraction...

Activated carbon was prepared from Enteromorpha prolifera by zinc chloride activation. The adsorption behaviors of three reactive dyes (Reactive Red 23, Reactive Blue 171 and Reactive Blue 4) onto this biomass activated carbon were investigated in batch systems. The experimental findings showed that the removal efficiencies of three dyes onto activated carbon were maximum at the initial solutio...

Background: Gingival overgrowth is a common clinical finding that most often represents reactive hyperplasia as a result of inflammatory gingival disease related to dental plaque. Irritation fibroma (IF), pyogenic granuloma (PG), peripheral ossifying fibroma (POF), and peripheral giant cell granuloma (PGCG) are non-neoplastic enlargements of the gingiva that are categorized as reactive hyperpla...

  Abstract In order to investigate the effect of deterioration on germination indices and enzymes activity of flax oil seed (Linum usitatissimum L.) Red Bazrak genotype, a factorial experiment was conducted base on completely randomized design with four replications in laboratory of seed technology at Yasouj University, 2015. The factors included the temperature at 4 levels (15, 25, 35 a...
