The paper provides a floristic account of the S. R. T. Campus (HNB Garhwal University, Tehri Garhwal, Uttarakhand) which enumerates 193 taxa, distributed under 158 genera and 70 families Angiosperms, Gymnosperms Pteridophytes. Life form analysis revealed presence 65.28% herbs, 17.62 % shrubs 12.44 trees, and. climber 4.66%. Asteraceae, Poaceae, Fabaceae, Lamiaceae, Rosaceae as dominant (in term...

A new VOF Type III-G.S stain was applied to histological sections of different organs and tissues of healthy and pathological larvae, juvenile and adult fish species (Solea senegalensis; Sparus aurata; Diplodus sargo; Pagrus auriga; Argyrosomus regius and Halobatrachus didactylus). In comparison to the original Gutiérrez VOF stain, more acid dyes of contrasting colours and polychromatic/metachr...

A simultaneous determination method of saccharin (SA), sorbic acid (SOA), benzoic acid (BA), p-hydroxybenzoic acid ethyl (PHBA-Et), p-hydroxybenzoic acid isopropyl (PHBA-isoPr), p-hydroxybenzoic acid propyl (PHBA-Pr), p-hydroxybenzoic acid isobutyl (PHBA-isoBu) and p-hydroxybenzoic acid butyl (PHBA-Bu) in foods by HPLC was examined. A mixture of acetonitrile-water (1:1) was used to extract thes...

Environmentally benign processes involving supercritical fluids have been investigated as alternatives to conventional solvents due to the increasing awareness of environmental issues. Carbon dioxide is considered to be a “green” solvent as it is nontoxic, nonflammable and non-reactive under most conditions. Supercritical carbon dioxide (scCO2) is a widely used solvent to enhance processing per...

Tartaric acid modified wheat bran was utilized as adsorbent to remove methyl blue, a basic dye from aqueous solution. Batch experiments were carried out to study the effect of various experimental parameters such as initial solution pH, contact time, initial dye concentration and adsorbent dosage, on dye adsorption. The results showed that the modification of wheat bran by tartaric acid signifi...

Parathyroid glands from laying hens were also  xed in percent glutaraldehyde in phosphate buffer (0.1 M, 7.3 pH) for araldite embedding and used for electron microscopy. For routine histological observations, sections of 5 to 6 um thickness were cut and stained by, Mayer’s haemalum and eosin-phloxine, Masson’s trichrome, Crossman’s modi cation of Mallory’s triple stain, van Gieson’s method fo...
