Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2007年第11期8卷 1725-1730页

作者： topU lker Bekir BLR Turhan Department of Civil Engineering Eski■ehir Osmangazi University Eski■ehir 26480 Turkey

In recent years, the usages of by-products and wastes in industry have become more important. The importance of the sustainable development is also of increasing. The utilizations of wastes, as mineral admixture or fine aggregate, reduce the consumption of the natural resources and improve the durability of concrete. In this study, the effect of the fineness on the high temperature and sulphate resistances of concrete mortar specimens, produced with ground granulated blast-furnace slag (GBFS) replacing cement, is investigated. The compressive and flexural strength test results for all series related to durability effects, exposing temperature and solutions, exposure times for these durability effects, slag content and fineness are discussed. Conse- quently, the optimum slag contents are determined for producing the sulphate and high temperature resistant mortars.

Surface and Hydrogen Sorption Characteristics of Various Activated Carbons Developed from Rat Coal Mine （Zonguldak） and Anthracite

引用

Chinese Journal of Chemical Engineering 2011年第6期19卷 931-937页

作者： Atakan top rak Turkan Kopac Department of Chemistry Zonguldak Karaelmas University 67100 Zonguldak Turkey

Activated carbon samples were developed from coal samples obtained from a coal mine, rat （Zonguldak, Turkey） and anthracite （Siberia, Russia）, applying pyrolysis in a temperature range of 600-900 ℃ under N2 flow, and activation using chemical agents such as KOH, NH4Cl, ZnCl2 at 650 ℃. Nitrogen adsorption at low temperature （77 K） was used to characterize the activated carbon samples, and their pore structure properties including pore volume, pore diameter and pore size distribution were determined by means of the t-plots and DFT methods. The surface area values were higher for rat coal samples than for anthracite one, and for the rat coal samples treated with KOH ＋ NH4Cl ＋ ZnCl2 at 650 °C [Rat650（2）] there are highest surface area and total pore volume, 315.6 m2·g^-1 and 0.156 ml·g^-1, respectively. The highest value of the hydrogen sorption capacity was found as 0.71% （by mass） for the rat coal sample obtained by KOH ＋ ZnCl2 treatment at 650 °C [Rat650（1）].

Empirical Analysis of Agricultural Policy Impacts of Senegal for food Self-sufficiency： The Stochastic Frontier Production of Rice and Maize in Senegal River Valley

引用

Journal of Statistical Science and Application 2017年第3期5卷 104-113页

作者： ARAME top KWANSOO KIM Seoul National University/Department of Agricultural Economics/SOUTH KOREA KOPIA Senegal/ISRA/SENEGAL

The stochastic production function estimates of rice and maize in Senegal River Valley demonstrate the possibility to reach self-sufficiency of rice in Senegal. Nonetheless, its fulfillment requires many accompanying measures in rice and maize production. These measures include all upstream and downstream activities related to agricultural production for their efficiency and sustainability in rice and maize production to maintain the country＇s comparative advantages and competitiveness. Then priorities should be given to agricultural infrastructure building, establishment of credit markets, and providing an easy access of production factors （e.g., improved land, fertilizers, improved and certified seeds, as well as agricultural machines）. Furthermore, policy makers should provide a larger incentive in terms of producer price to encourage farmers to increase considerably their outputs, thereby farmers face smaller risk of having non-sold outputs. And during an early harvesting period, appropriate policy measures are in need to prevent farmers from dumping their products under severe social and economic pressures such as children schooling and loan payment, etc
