Energy from renewable sources inTurkey: Status and future direction
(Taylor & Francis Inc, 2004)Turkey is an energy importing country. Turkey's indigenous energy sources are limited and the country is heavily dependent on the import of primary energy from abroad. More than half of the energy requirement has been ... -
Utilization of ceramic wastes in the construction sector
(Trans Tech Publications LTD, 2004)Ceramic wastes causing a serious problem are polluting the environmental problem in Eskisehir Region, Turkey. In this paper, were studied three wastes, ceramic mud wastes (CMW), crushed ceramic tile wastes (CCTW) and ceramic ... -
Utilisation of waste bricks as cement replacement material in concrete production
(Trans Tech Publications LTD, 2004)Waste clay bricks constitute one of the important groups of the waste materials that cause environmental problems unless the proper use of these materials is found. In this study, the clay brick wastes obtained from a ... -
Determination of soil hydraulic properties using pedotransfer functions in a semi-arid basin, Turkey
(Copernicus Gesellschaft Mbh, 2004)Spatial and temporal variations in soil hydraulic properties such as soil moisture 0(h) and hydraulic conductivity K(theta) or K(h), may affect the performance of hydrological models. Moreover. the cost of determining soil ... -
Thermal shock behaviour of magnesia-spinel composites
(Elsevier Sci LTD, 2004)The incorporation of up to 30% of spinel powder of median particle sizes 3, 11 and 22 mum into dense magnesia gives improved resistance to thermal shock as indicated both by the R''' thermal shock resistance parameters ... -
The experimental optimization of the electrosynthesis of manganese(III) acetate in a bipolar packed-bed reactor
(Elsevier Science Sa, 2004)The electrochemical oxidation of Mn(II) acetate to Mn(III) acetate, which is an industrial oxidizing agent and catalyst, in acetic acid medium was investigated in a bipolar packed-bed electrode cell with mesh spacers. The ... -
Investigation of Turkish poppy seeds and seed oils
(Kluwer Academic/Plenum Publishers, 2004)The oil yields. fatty acid compositions, and total protein contents of three varieties of Turkish poppy were investigated. Solvent extraction of yellow seed gave the highest oil yield (49.2%). while white seed (36.8%) and ... -
Utilization of coal combustion fly ash in terracotta bodies
(Trans Tech Publications LTD, 2004)In this present work, coal combustion fly ash from a power plant in Turkey was used in combination with a traditional raw material in terracotta production with the aim of having a product with improved physico-mechanical ... -
Use of tuncbilek thermal power plant's fly ash in stoneware glazes as a colouring agent
(Trans Tech Publications LTD, 2004)With the increased energy needs thermal power plants enlarge their production rates. In spite of high productivity in energy supplies, the concentration of fly ash filtered in the chimneys of these plants raises subsequently. ... -
Production and characterisation of pigments produced using grinding waste from cast iron foundry
(Trans Tech Publications LTD, 2004)The brown and black pigments are generally synthesised from different powders such as iron (111) and chromium (111) oxide powders. In this study, iron-chromium pigments by using grinding waste from cast iron foundry as ... -
Fracture behaviour of magnesia and magnesia-spinel composites before and after thermal shock
(Elsevier Sci LTD, 2004)Microstructural changes, as a consequence of the thermal expansion mismatch between magnesia and spinel phases, and fracture behaviour of magnesia and spinel composites have been investigated as a function of spinel content ... -
Fast pyrolysis of linseed: product yields and compositions
(Elsevier Science BV, 2004)Fixed-bed fast pyrolysis experiments have been conducted on a sample of linseed (Linum usitatis-simum L.) to determine particularly the effect of pyrolysis temperature, heating rate, particle size and sweep gas flow rate ... -
