13. Photocatalytic degradation of ferricyanide as synthetic gold mining wastewater using TiO2 assisted by H2O2
Abstract Ferricyanide Fe(CN) 6 3- is one of the most stable cyanometallic complexes present in the gold mining effluents. This cyanocomplex is hard to degrade by natural attenuation and generates a negative impact on aquatic environments. Although free cyanide (CN-) can be obtained by acidifying the solution, the CN- is lethal for all forms of life. The oxid

14. Foliar application of molybdenum on cover crops and response of common beans in successive cultivation
ABSTRACT The effects of foliar application of Mo and use of N from cover crops (Crotalaria juncea L. and Canavalia ensiformis (L.) DC) on the performance of common beans were investigated in this study. Field experiments were carried out in a succession planting system (cover crops - common beans), and nitrate reductase activities were evaluated in the labor

16. Strontium Oxide Decorated Iron Oxide Activated Carbon Nanocomposite: A New Adsorbent for Removal of Nitrate from Well Water
In the present study, activated carbon was magnetized by iron oxide and modified by strontium based nanoparticles (FeAC@Sr) to introduce it as an efficient favorable adsorbent for the removal of nitrate ions from underground water. The decorated adsorbent was characterized in terms of size, structure, morphology and composition using scanning electron micros

18. The Effect of Water Parameters and Dissolved Minerals on the Hematological Parameters of during Breeding Period Catfish (Silurus glanis)
Abstract In this study, the blood parameters of catfish (Silurus glanis Linnaeus, 1758) inhabiting Çelik Lake (Adıyaman, Turkey) were investigated. The study was conducted between April 2013 and October 2013. After obtaining a blood sample from each catfish has been hematologically analyzed. Then, the water temperature, dissolved oxygen, pH, calcium, magne

19. In vitro biological activities of silver nanoparticles synthesized from Scedosporium sp. isolated from soil
One of the important fields in nanotechnology is the development of an environment friendly method for the synthesis of nanoparticles. Many approaches show that microorganisms are the most reliable tools for biosynthesis of nanoparticles compared to physical and chemical methods. In our study, fungi have been exploited for extracellular production of metal n

20. Comparison of subcutaneous inflammatory response to commercial and engineered zinc hydroxyapatite implants in rabbits
RESUMO A hidroxiapatita (HA) é amplamente utilizada como biomaterial para reparo ósseo e revestimento de próteses metálicas. As principais limitações dos atuais compostos comerciais de hidroxiapatita sintética incluem alto custo e menor disponibilidade, especialmente para fins de medicina veterinária. Além disso, acredita-se que a biocompatibilidade
