alcoholic solutions in the first decimal hahnemanian dilution<br />
(DH1). We used a spectrophotometric method to determine the<br />
concentration of these two vitamins. Riboflavin has shown a UV<br />
spectrum with the absorbance at a wavelength of 445 nm and<br />
thiamine has shown a UV spectrum with an absorbance between<br />
246 and 300 nm.<br />

Studies regarding life cycle of paper products frequently<br />
compare environmental impact for various product management<br />
solutions after usage. Thus it is shown that recycling paper has a<br />
smaller impact upon environment compared with incineration<br />
and storage.<br />
Replacing virgin tree fibers with recovered fibers reduces<br />
demand for wood, which eases pressure to harvest forests and<br />
convert natural forests into tree plantations. Making paper from<br />
used paper requires less energy and is generally a cleaner<br />
manufacturing process than making paper from trees. And<br />
because it diverts usable paper from the waste stream, recycling<br />
cuts both solid waste and greenhouse gas emissions created when<br />
paper decomposes in landfills.<br />
Usage of recycled paper is a good alternative in our times for<br />
gradual replacement of “traditional” paper and is also a good<br />
decision due to benefits regarding environment preserving<br />
worldwide, generating important resource savings.<br />
Paper recycling and reuse is associated environmental and social<br />
costs, as a preferred alternative in waste minimization hierarchy<br />
in the manufacturing of non-trees eco-friendly paper.<br />

From commercial powders and mechanically alloyed powders<br />
three types of samples were prepared, one type that contains only<br />
commercial powder designated as 0%_MA, one with 50%<br />
commercial powder and 50% mechanically alloyed powers,<br />
designated as 50%_MA and the last one with only mechanically<br />
