Influence of interstitial filling on breakage kinetics of gypsum in ball mill
(Elsevier, 2011)
Gypsum is an industrial material used in many applications such as building and chemical industry, fertilizer manufacture, medicine and dentistry. In these industries, there is need for finely ground gypsum. Energy consumption ...
Defect characterization in neodymium doped thallium indium disulfide crystals by thermoluminescence measurements
(Elsevier B.V., 2016)
Characteristics of defect centers in neodymium doped TlInS2 single crystals have been investigated in virtue of thermoluminescence measurements carried out at low temperatures (10–300 K) with various heating rates between ...
An investigation on the effects of the ball filling on the breakage parameters of natural amorphous silica
(Elsevier B.V., 2016)
The effects of ball filling on the selection (Si) and breakage functions (Bi,j) for the natural amorphous silica were investigated in this paper. At four levels (20%, 30%, 40% and 50%) of ball filling, the selection functions ...
The effects of ball filling and ball diameter on kinetic breakage parameters of barite powder
(Elsevier, 2012)
The absolute fineness of the ball diameter and the ball charge grading are important factors for the optimal operation of a ball mill. Therefore, the effects on breakage kinetics of the ball diameter and the fractional ...
A new size distribution model by t-family curves for comminution of limestones in an impact crusher
(Elsevier, 2011)
In the evaluation of crushers, t-family curves obtained from single particle test methods are frequently used. It is known that there are many difficulties and problems in these tests. In this study the breakage behaviour ...
A simple flow injection spectrophotometric procedure for direct determination of copper(II) in environmental samples
(Chemical Publishing Co., 2014)
A new simple, rapid and sensitive flow-injection spectrophotometric detection method has been developed for the on-line determination of copper(II) in environmental water samples. The method is based on the measurement of ...
Dichromate and phosphate sorption capacity of bis formyl calix[4]arene on superparamagnetic iron oxide nanoparticles in aqueous phase
(Chemical Publishing Co., 2016)
Calix[4]arene derivatives were added into aqueous phase phosphate and dichromate solutions in order to investigate sorption capacity at pH of 1.5 to 5.5. A 25 mg of polymers magnetic calix[4]arenes derivatives was added ...
The role of protein Z and protein Z-dependent protease ınhibitor polymorphisms in the development of prosthetic heart valve thrombosis
(2017)
BACKGROUND AND AIM OF THE STUDY: Protein Z (PZ) is a vitamin K-dependent factor that is synthesized mainly by the liver. It acts as an activator of serpin, the protein Z-dependent inhibitor (ZPI), which inhibits factor Xa. ...
Cold effect in median nerve conductions in clinical carpal tunnel syndrome with normal nerve conduction studies
(Churchill Livingstone, 2019)
Clinical diagnosis of carpal tunnel syndrome (CTS) is confirmed by nerve conduction studies (NCS). In some cases, NCS may be normal. We aimed to demonstrate changes of distal motor latency (DML) and nerve conduction velocity ...
An ultrastructural study, effects of Proteus vulgaris OX19 on the rabbit spleen cells
(2013)
Effects of Proteus vulgaris OX19 on the spleen cells of rabbits were investigated. Control group (n= 5) and Proteus treated group (n= 5) of New Zealand male rabbits were used in this study. Bacteria were injected to the ...
