Chadwick et al[4] reported that the organic N supplied with farm manures was considerably more ‘mineralizable’ than that from crop residues.
The experiment was conducted at the experimental station of the Institute of Applied Ecology, Chinese Academy of Sciences, where is described by Yu et al in detail[9].
Soil total organic C (TOC) was determined with an Elementary Vario EL Ⅲ elemental analyzer (Elementary Co.
The results agreed with many leaf litter decomposition experiments reported by Wang et al[14].

Mohammed and Pandey [24] and Olowu et al. [25] confirmed the observation of the study that compressive strength of concrete increase as the water cement ratio decreases; other studies conducted by Ranjith et al. [26], Mallikarjuma et al
[27], Eskandari-Naddaf and Kazemi [28], Yu et al. [29], Nyiutsa et al. [30] and Omotola and Idowu [31] also confirm the result of the study.

Also, cobalt catalysts were affected by the supports through stream reforming of ethanol experiments, as reported by Funihiro et al. [13].
The precursor used in this experiment was aluminum isopropoxide (Al(OC3H7)3) (98+%, Aldrich).
The aluminum precursor was added to the distilled water of molar ratio Al:H2O=1:100 refluxing at 353K.

Also, this analysis shows (in Table-1) sufficient amount of Al, Ti and V contents but it has to expenses during melting of deoxidation purpose [5, 6].
