ETI Aluminyum A.Ş., the primary aluminium manufacturer of Turkey, is also one of the major integrated plants of the world capable of performing production from mining until end product. The alumina refinery was designed on a certain boehmitic bauxite quality basis. However, bauxite properties have changed over the years, resulting in the urgent need for […]
One of the serious problems in polybutadiene rubber (PBR) production units is the color change in products, which is due to aging and the inability of antioxidants to protect the product, especially at high temperatures. In this study, the effects of amine-type antioxidant [octylated diphenylamine (OD)] and non-amine-type antioxidant (Irganox 1520) on the color yellowness, […]
The corrosion and corrosion inhibition of Pb and Pb–In alloys in HCl solution, were investigated. The study was performed in the absence and presence of the phytic acid (PA) inhibitor using potentiodynamic polarization and electrochemical impedance spectroscopy measurements, and complementary by scanning electron microscope (SEM) and X-ray spectroscopy analysis (EDX) investigations. The obtained outcomes showed […]
Inhibition action of seroquel on corrosion of zinc in 0.1 M HCl solution was investigated using weight loss, electrochemical potentiodynamic polarization and impedance spectroscopic techniques. Corrosion inhibition efficiency showed the positive effect with increase in concentration of inhibitor and with the increase in temperature. Results obtained from all the methods are in good agreement with […]
High-end applications require a very tall vertical extraction column in some cases which deteriorates protection against radiation and cannot be employed for indoor applications. On the other hand, horizontal extraction columns offer higher efficiency and pretension, but lower maximum throughput. In order to address this issue, the L-shaped pulsed extraction column is a new type […]
By nthesizing nano zinc oxide with different morphologies, such as spherical, snowflake like, and starfish like, and utilizing its unique physical and chemical properties, combined with the cavitation effect of ultrasound, it is expected to achieve effective degradation of dye wastewater. In the comparative experiment of using nano zinc oxide, ultrasound, ultrasound+nano zinc oxide to […]
Removal of metals from wastewaters causes a big concern from the environmental point of view due to their extreme toxicity towards aquatic life and humans. Application of As(III) from aqueous solution by ZnO nanorods as adsorbent has been investigated in the present study. The synthesized nanorods were characterized by XRD, FT-IR spectroscopy, SEM, and thermogravimetric […]
Objective: To investigate the effect of sevoflurane postconditioning on the levels of Nrf2 expressed in the early stage of hepatic ischemia-reperfusion injury (HIRI) in rats and to explore the possible Mechanism of sevoflurane postconditioning in attenuating HIRI. Methods: 24 S.D. rats were randomly divided into Sham group, Sevoflurane group, HIRI group, and HIRI+Sevoflurane group. The […]
Objective: To probe the clinical Effect of traditional Chinese medicine (TCM) nursing in cardiovascular patients. Methods: A total of 120 patients with cardiovascular disease treated in our hospital were randomly separated into a control group (C.G., n=60) and a research group (R.G., n=60). Patients in the C.G. received routine medical care. Patients in the R.G. […]
Diabetes mellitus is a common disease that currently affects more than 3 million people in Iran. Many years ago, medicinal herbs have been used to treat many diseases. In this study, the evaluation and comparison of blood glucose lowering agents from different parts of mango (leaf, peel, and fruit) was studied. In this experimental study, […]
