In the present paper, attention is paid to synthesis and investigation swelling behavior of a superabsorbent hydrogel composite based on Pectin (Pec) and polyacrylonitrile (PAN) in the presence Kaolin powder. The physical mixture of Pec, Kaolin and PAN were hydrolyzed by NaOH solution to yield H-Pec-poly (sodium acrylate-co-acrylamide)/Kaolin superabsorbent hydrogel composite. A proposed mechan...
Field mapping, colour, particle size distribution, pH and x-ray diffraction studies were undertaken to elucidate the genesis of Ediki kaolin. The kaolin occurs within the Mungo formation of upper cretaceous age, ascribed to the Douala sedimentary basin. The kaolin profile consists of upward coarsening sandstone – siltstone – sandstone sequence with a gradient of 35 to 40°. Texturally, the kaoli...
We investigated whether radiation-induced pica, a behavior characterized by the eating of a non-food substance, such as kaolin, can be used as an index of radiation-induced vomiting in rats. Since there was an individual difference in the susceptibility to pica, we selected rats that actually ate kaolin following X-ray irradiation, and used them for the experiment. The total-body irradiation (T...
In this paper, two types of material forming filter cakes with different compressibility and compactness, namely CaCO3 and Kaolin were examined in a new test cell. Our measurements in the new test cell showed that C–P test data could predict reasonably well the actual filtration process. Taking into account the effect of side-wall friction, there were about 2–15 and 1–16% differences in average...
the processing methods of kaolin are based on its high a b i l i t y of water absorption and converting easily to fine perticles of kaolin dispersed in water. so, depending on the dimension of impurities of kaolin, one can choose the pr6pe1: classifier f o r removal of them. sometimes, the texture of kaolin is not suitable for water absorption and resultant dispersion. in this case,the ore shou...
Lime stabilization is one of the techniques that can be used for improving the engineering properties, particularly the strength, of soft clays. This paper aims to investigate the effect of hydrated lime on the strength and microstructure of lime treated clays. In order to illustrate such effect, a series of laboratory tests were conducted. Atterberg limits, compaction tests, unconfined compres...
In many cases, the hydrocyclone control is desirable for efficient separation especially in case of changing feed conditions. Control concept based on exact mathematical models is not satisfactory due to the complexity of the physical process. In this case, fuzzy control is a suitable solution. The data are primarily derived from an optical sensor that monitors the outside view of the free unde...
The influence of particle shape (aspect ratio) on the intrinsic viscosity is investigated, taking three Czech kaolin products (floated kaolins) as paradigmatic examples. An average aspect ratio is obtained for each kaolin from a comparison of particle size measurements using sedimentation and laser diffraction. The intrinsic viscosity is obtained by a multistep procedure: firstly, flow curves a...
inflammatory condition is the consequence of defensive mechanism of immune system against viral and bacterial infection, tissue injury, uv radiation, stress and etc. persistently acute inflammation leads to chronic phase which is characterized by production of pro-inflammatory mediators from t cells. these molecules (e.g. il-6, tnf-α, il-1β and il-17) are mostly pleiotropic cytokines involved i...
introduction and aims: noscapine has been recently known as an antagonist of bradykinin, and in this study its effect on the animal model of acute pancreatitis has been evaluated. materials and methods: 49 male wistar rats have been evaluated in five experimental and four control groups. common bile duct has been ligated by means of surgery to induce acute pancreatitis in rats. the resulted inf...
