In the drinking water treatment, the aesthetic and color problem are caused by the manganese which is occurring and present in the surface, lake and ground water. The most common treatment processes for removing manganese are known for oxidation followed by filtration. In this study, the manganese sand process was used for removing manganese with river bank filtrate as a source. In the manganese sand process, the residual chlorine and pH are important factors on the continuous manganese oxidation. In addition, space velocity (SV) and alum dosage are play a role of manganese removal. Even though manganese removal increased with increasing chlorine concentration, the control of residual chlorine is actually difficult in this process As the results of tests, the residual chlorine concentration as well as manganese removal were effectively achieved at pH 7.5. The optimum attached manganese concentration on manganese sand was confirmed to 0.3mg/L by the experimental result of a typical sand converting to manganese sand.

Introduces three shelter methods for high temperature environment used in spacecraft and solid rockets. Ablation is one of the methods that receives the widest applications.The usage, types and methods of evaluation of ablative materials are explained and the ablative performances of polymers in ablative materials are compared. Conclusions show that phenolic resins have fairly good overall ablative performance. A Classification and brief introduction are made for the references to ablative phenolic resins obtained by consulting. Finally, the tendency of ablative polymers and the author's development work in ablative phenolic resins are introduced.

Abstract In the smelting process of high manganese steel, the volatilization of manganese will be accompanied. In this article, the volatilization of manganese in high manganese steel was studied by simultaneous thermal analyzer. The results show that the volatilization rate of manganese in high manganese steel increases with increasing temperature and holding time. It is proved by experimental study and data analysis that manganese volatilization follows the first-order kinetics model, and the empirical formula of manganese evaporation is derived. The volatile products of manganese were analyzed by scanning electron microscopy and X-ray photoelectron spectroscopy. It was found that the volatile components of manganese mainly consisted of MnO, Mn 3 O 4 , Mn 2 O 3 , and MnO 2 . Combined with thermodynamics, the mechanism of manganese volatilization is further analyzed, and two forms of manganese volatilization in high manganese steel are revealed. One is that manganese atoms on the surface of high manganese steel and oxygen atoms in the gas form different types of manganese oxides and then volatilize at high temperature. The other way is that Mn atoms vaporize into Mn vapor and evaporate in high temperature environment, and then are oxidized into different types of manganese oxides. The results of theoretical calculation and experiment show that manganese volatilization is mainly in the first form.

Effects of manganese availability on soybean (Glycine max) growth,acquisition of manganese,iron and phosphorus were investigated. The results showed that soybean growth was significantly inhibited when manganese was deficient or beyond 50 μmol·L-1 in the media. With increase of manganese concentration,more manganese was accumulated in plants,especially in old leaves. Antagonistic effects were observed between manganese and iron. Acquisition of phosphorus was not affected by manganese availability. However,distribution of phosphorus in old and young leaves was significantly influenced by manganese deficiency.

In the past, the standard of care for women with abnormal cervical cytology has been the performance of colposcopically guided biopsy, followed by conization or large loop excision of the transition zone (LLETZ) where biopsy revealed pre-cancerous or cancerous areas. More straightforward protocols are emerging which advocate performing LLETZ in all women with highly suspicious cytology, suspicious colposcopic impression, or the presence of high-risk oncogenic human papilloma virus (HPV) strains in their cervical swabs. This, theoretically, would reduce the rate of false-negative diagnoses, but at the price of overtreating a significant number of healthy women.
