Based on Core GGC-6 from the South China Sea (SCS) and Core GGC-29 from the Sulu Sea,planktonic and benthic foraminifera and organic carbon measurements were used to evaluate the Water mass conditions in these sea areas during the last glacial age. The results show that the higher organic carbon contents in the SCS and Sulu Sea during the last glacial period were mainly caused by low dissolved oxygen concentrations in bottom waters and that in the last glacial to Holocene, the fluctuation of dissolvd oxygen in the bottom weters was large in the SCS and reatively stable in the Sulu Sea. In addition, increased precipitation reduced surface water salinities, which at the water column to be more stratified in the SCS and Sulu Sea during the last glacial period. This process lowered dissolved oxygen concentrations in bottom waters, which resulted in better preservation of organic matter in both basins.

The experiments were carried out at the Post Graduate Research Center, to study the influence of Gibberellic Acid (50 ppm) and oxygenated Peptone (1% aqueous solution) on chick pea (Cicer arietinum L. cv. Vijay) during germination by giving pre-sowing soaking treatment for 6 hours using petriplate method. Both the treatments enhanced the germination process. GA treatment was useful to increase shoot length, mobilization efficiency, emergence index, speed of germination and co-efficient of germination while oxygenated peptone showed an upper hand in root length, shoot/root ratio, biomass and vigour index. GA led to comparatively more synthesis of nucleic acids while oxygenated peptone showed more increase in total carbohydrates and soluble protein content. However, the activity of enzymes like amylase, catalase and protease showed upper hand with oxygenated peptone as compared to GA. In fact GA is costlier and can not be used in organic farming as it enters metabolic pathways of plant and alters them. Hence the use of oxygenated peptone is recommended being less expensive and usable under organic farming condition as it does not enter the plant metabolic pathways and yet brings about significant positive effect.

The bio-oil derived from pyrolysis of straw can be selectively converted into high-purity hydrogen by coupling three steps:(i)steam refonning(SR)of di tierent bio-oils,(ii)water-gas shift(WGS),and(iii)the removal of *** catalytic SR reaction over the NiLaTiAl catalyst,coupled with a low-temperature WGS reaction with the CuZnAl catalyst,promoted the conversion of various oxygen-contaming organic compounds in the bio-oil into hydrogen and carbon *** the optimized condition,light bio-oil achieved the highest conversion(99.8%,molar fraction),with a high hydrogen yield of 16.4%(mass traction)and a H2 purity of 99.94%(volume fraction).The carbon deposition on the NiLaTiAl catalyst was the main factor caused catalyst *** of hydrogen from different bio-oil model compounds was also investigated in detail.

The flowers of ZhaoFen and RouFurong may contain essential oils with natural aromatic ingredients. In the present work, the chemical compositions of essential oil of Paeonia suffruticosa Andrews from the flowers of ZhaoFen and RouFurong grown only in China were investigated by GC-MS analysis. The results indicate that there are 27 constituents in ZhaoFen and 29 constituents in RouFurong, which account for 96.04% and 95.90% of the oils of ZhaoFen and RouFurong, respectively. The major components of the essential oils are character-rized by oxygenated terpenols, and their content is, respectively, 85.06% and 83.47%. The essential oil of Paeonia suffruticosa Andrews was reported for the first time on the aerial parts.
