background and purpose:consumption of baking soda, as a primary material for preparation of bread dough, has been banned due to its health complications in iran. so bread production in our country faced difficulties and one part of them is related to health issues which are bread production. also, in some cases, baking soda is used in the bread production. this study was done to study the envir...

Abstract Molar masses, Mark-Houwink-Sakurada (MHS) exponents, and refractive index increments (dn/dc) for three lignins were determined without derivatization by multi-detector gel permeation chromatography (GPC) in dimethylformamide (DMF) with 0.05 M lithium bromide (LiBr). The lack of effectiveness fluorescence filters on molar mass determination GPC-multi-angle laser light scattering (MALS) ...

cellulose is a raw material which is extensively used in the manufacture of paints, papers, textiles, agricultural products and cosmetics. the waste of sugar beet pulp after titration is a source of cellulose. the current study was carried out to study the possibility of cellulose production from sugar beet pulp waste at titration stage as a 3×3×2 factorial study on the basis of a randomized co...

Background The prevalence of overweight and obesity has increased dramatically in both adults and children in the last three decades in the n California, 62% of adolescents ages 12-17 and 41% of children ages 2-11 drink at least one soda or other sweetened beverage every day. In addition, 24% of adults drink at least one soda or other sweetened beverage on an average day. Adults who drink soda ...

BACKGROUND Across the United States, many states have actively banned the sale of soda in high schools, and evidence suggests that students' in-school access to soda has declined as a result. However, schools may be substituting soda with other sugar-sweetened beverages (SSBs), and national trends indicate that adolescents are consuming more sports drinks and energy drinks. This study examined ...

Amelia Vader amelia.vader@ gmail.com Evans School of Public Affairs MPA 2013 AbstrAct Introduction Rising obesity rates and lower state and local revenues have resulted in more state governments adopting taxes on soda over the last ten years. The intended effects of soda taxes are to reduce the amount of soda purchased and consumed. This research uses data from the Behavioral Risk Factor Survei...

residual lignin of wood after mwl isolation was dissolved with 1-butyl-3-methylimidazolium chloride ionic liquid. chemical structure of isolated mwl from poplar wood (popolus deltiodes) and dissolved residual lignin were characterized with gas chromatography and 1d, 2d nmr techniques. analytical results showed that  popolus deltoides wood has more 4-(3-hydroxy-1-propenyl)-2-methoxy phenol units...

Gordonia westfalica Kb1 and Gordonia polyisoprenivorans VH2 induce the formation of an extracellular superoxide dismutase (SOD) during poly(cis-1,4-isoprene) degradation. To investigate the function of this enzyme in G. polyisoprenivorans VH2, the sodA gene was disrupted. The mutants exhibited reduced growth in liquid mineral salt media containing poly(cis-1,4-isoprene) as the sole carbon and e...

a fourth-generation ziegler-natta catalyst was prepared to synthesize polypropylene (pp), which was stabilized by in situ polymerization employing lignin as antioxidant. the antioxidant properties of lignin were compared with those of the commercial antioxidant irganox 1010. the presence of lignin in the reaction medium slightly decreased the catalytic activity of the reaction. the isotacticity...
