“…The fresh samples of silage were weighted and then dried for 24 hours in hot air oven in the lab, all of the samples were then treated with the combustion method and the remaining ash after the complete combustion was weighed and the percentage ash content was calculated with the formulae of Ukiwe et al (2008).…”

L ivestock sector of Pakistan has an important role in Pakistans agriculture system as a major portion of land area used in Pakistan is under fodder and forage cultivation. In agriculture, livestock as a subsector contributes a major part to value addition in agriculture. Currently, it contributes 60.6% to overall agriculture and 11.7% to GDP during 2019-20. Gross value addition increased with 2.5% during last year (Pakistan Economic Survey, 2019-20). There is continuous growth in population, urbanization is increasing, per capita income is increasing and apart from all this, there are increasing opportunities for Abstract | Silage is the term used for forage with a high moisture content preserved by fermentation. The main objectives of making silage are to preserve forage for use in those seasons when fresh forage is not available, to preserve forage when there is a surplus of it during the growing season, and to preserve forage that cannot be grazed. The experiment was carried out at research area, Department of Agronomy, College of Agriculture, University of Sargodha to evaluate the combined effect of sunflower and maize crop for the quality production of silage for enhancing the growth and production in the animals. Six maize hybrids were used along with the sunflower, tree were twelve treatments, each maize with sunflower as intercrop and only maize hybrids as solo crop. Outcome of research revealed that both of sunflower heads and maize plants have better combination for the silage production and the quality parameters like pH, moisture content, protein content, fat content and ash contents. The moisture contents of both the samples and combined silage had not much difference among them, but the protein content, fat content and the pH of the combined silage had remarkable difference among them. The Syngenta-8711 + sunflower and Monsanto-6142 + sunflower varieties were best and had maximum mean values for most of quality parameters, (Fat contents: 14.99%, moisture contents: 38.66%, protein contents: 17.41% and pH: 4.10). These varieties can be grown as intercrop with sunflower to get higher yield and quality of silage.

“…The bonds between molecules are broken and make volatile matter in the material lose into gas and liquid products so that the carbon fix is higher 38) . The residue left after all combustible matter in the activated carbon has been entirely burned away is referred to as ash content, and it reflects the quality of mineral matter in the liquid under test 39) . The ash content of carbon after activation with O2 oxidant gas decreased from 14.86% to 9.02%.…”

This study synthesized the activated carbon as material support for platinum catalysts in fuel cells application. The pyrolytic carbon black from the waste tyre was activated through physical activation using oxygen gas in a vertical bed column. The activation influencing factors are then examined, which include the activation temperature, the activation time, and the composition of oxidant oxygen gas in the activation. The results showed that the optimum operating conditions for the carbon black activation into its corresponding activated carbon are activation temperature at 300℃, activation time for 1 hour with pure oxidant oxygen gas. The resulting activated carbon was also successfully tested as a potential platinum-fuel cell catalyst support (Pt/AC) in the methanol oxidation reaction (MOR) in Direct Methanol Fuel Cell (DMFC) application, as indicated from the electrochemical testing, i.e. the cyclic voltammetry (CV) and linear sweep voltammetry (LSV) measurement. The CV measurement showed that this Pt/AC catalyst generates the region of hydrogen adsorption/desorption (Hads/des), the double-layer charging and discharging, and the CO oxidation-reduction. In addition, during the LSV measurement, this Pt/AC catalyst showed the reactivity towards MOR with its current density of 0.0005 A.cm -2 at 0.6 V.

The ability of water hyacinth (Eichhornia crassipes) to adsorped polycyclic aromatic hydrocarbons from contaminated soil leachate was examined. Results obtained from analysis using GC/FID indicated that naphthalene (8.350 ?g/g) was the overall highest polycylic aromatic hydrocarbon adsorped at pH 4.0, while pyrene (0.057 ?g/g) was the least adsorped polycyclic aromatic hydrocarbon overall at pH 6.0. In ascending the pH from 2.0 to 6.0, there wasn’t any trend observed in PAH degradation, though, it was noted that polycyclic aromatic hydrocarbons degradation increased from pH 2.0 to 4.0, and then, sharply decreased at pH 6.0. This results thus lend credence to the fact that E. crassipes is a potential phytoremediator in removing polycyclic aromatic hydrocarbons from contaminated waste streams.
