objective: in order to study the effect of different concentrations of iba hormone on rooting of olive cuttings in spring and winter of 2012-2013 in a greenhouse in jiroft, iran. methods: a split-plot experiment was conducted on the basis of a randomized complete block design in which hardwood cuttings of one-year-old olive plants cv. manzanilla with the diameter of 0.7-1 cm were used. the main...

The majority of anthraquinone dye released to the environment come from antrapogenic sources. Several techniques are available for dyes' removal. In this study removal of reactive blue 29 (RB29) by an advanced oxidation process sequenced with single wall carbon nanotubes was investigated. Advanced oxidation process was optimized over a period of 60 minutes by changing the ratio of acetic acid t...

We have shown earlier, that an oxygen impurity content of >0.4 at.% (4000 ppm) strongly degrades the hardness of the nc-TiN/a-Si3N4 nanocomposites. Here we show that such impurities also hinder the phase segregation and formation of stable and strong nanostructure consisting of 3-4 nm size TiN nanocrystals "glued" together by about 1 monolayer thick interfacial Si3N4-like layer, thus apparently...

The application of naphthalene acetic acid (NAA) different concentrations (25, 50, and 75 ppm) was applied to grafted mango seedlings identify its effect on callus formation, diameter, shoot emergence, plant survival. NAA effectively reduced the number days mainly using ppm. Lower than this concentration exhibited a comparable same as untreated seedlings. survival showed no significant by apply...

The aim of this study is to determine suitable conditions for egg disinfection of gilthead sea bream (Sparus aurata), red porgy (Pagrus pagrus), and common dentex (Dentex dentex) with glutaraldehyde, hydrogen peroxide and iodine. The eggs were disinfected with 200 ppm glutaraldehyde (T= 2, 4, 8, 16 min), 300 ppm hydrogen peroxide and iodine (T= 5, 10, 15, 20 min) at four different contact times...

introduction: medical benefits of omega 3 fatty acids have appealeda lot of research to be done on of fish oil. among marine fish, kilka has the most industrial application. kilka oil contains significant amount of omega-3 fatty acids. in this study, physiochemical properties, fatty acid composition and stabilization of kilka oil were investigated. p- hydroxy benzoic asid, its methyl ester and ...

This study assessed the effect of acetic NaF solutions on stainless steel orthodontic brackets. Acetic acid was added to a 0.1% NaF solution to make two solutions, one with pH 3.5 and the other with pH 6. For the two different stainless steel brackets (Tomy, Dentaurum) used in this study, they had a similar elemental composition--except with Mo (molybdenum) in the Tomy bracket. The brackets wer...

In order to find a fast, high efficient determination method of Organophosphorus Pesticides (OPPs) residue because OPPs widely used in crops pest control fields in China are causing fearful risks for environment as well as animals and human health, traditional and advanced determination methods were discussed in the study. Based on the spectrum analysis technology combined colorimetric OPPs res...
