Wheat paste

Leather lettering pieces on the spines of leather-bound books are usually very thin and were attached with little paste. For this reason and because of chemical decay, many labels have either disappeared or can be levered off without difficulty. Reattachment with wheat paste can be hazardous for the novice because of the immediate weakening effect of the adhesive on the extremely thin and weak leather, which may also be darkened in the process. PVA is to be preferred because it has low water content. However, this may militate against its sticking to powdering leather, so it may be a good plan to paste the foundation of the panel and let it dry before reattaching the label with PVA. 

Tears are repaired with Japanese tissue, missing areas are filled in with paper similar to the artifact. Repair paper of specific caliper and tone is made in the leaf caster. Adhesives vary methyl cellulose, wheat paste, or a mixture of polyvinyl alcohol with rice paste. The mixture is most useful because it permits use of a warm tacking iron to hasten the drying process. Where missing areas have been patched, the restorer reconstructs only those lines and colors that are already discernable, lest the work be called an attempt at falsification.

Allelopathy in agriculture. Schreiner and his associates published several papers shortly after 1900 which indicated that certain crop plants produce compounds inhibitory to growth of the same and other crop plants (2). McCalla and Duley (43.44) reported the allelopathic effects of decaying wheat residues in 1948-1949, and many papers on allelopathic effects of crop plants have been published in the past three decades. 

Examples of allelopathy between weeds and crop or pasture species in Australia have been documented within the past decade. Lovett and Lynch (J ) discussed the association of Salvia reflexa Hornem. (mintweed), an annual member of the family Lamiaceae introduced to Australia from North America ( ). This species produces aromatics as well as water-soluble compounds that may be inhibitory to species such as wheat and sorghum. Kloot and Boyce ( ) documented inhibitory effects of allelochemicals produced by Polygonum aviculare L. (wireweed) on the annual Medicago species, important...

Bread Sample Preparation. The recipes for making white bread consisted of wheat flour (regular, 1 kg), water (520 ml), baker s yeast (25 g), improver mix (24 g), salt (20 g) and soya flour (0 or 30 g). For studying the shelf-life of soya containing improver mixtures (20 C, 80 % rH) an improver paste with 0.5 % and an improver powder with 2.5 % soya flour were used in the recipe without further soya flour addition. 

Pills made with paste Because the herbal ingredients are mixed with paste (made from rice or wheat flour), this type of pill is absorbed slowly and is especially suitable for ingredients that are toxic or have harsh actions which can easily irritate the stomach. This type of pill is also used for chronic conditions when gentle and steady effects are required.
