ABSTRACT: As compulsory courses, the ideological and political courses of instates of higher learning can strengthen the moral integrity and political awareness. They are also the main method of moral education in institutes of higher learning. Ideological and political courses can improve the comprehensive development of college students and enable college students to become eligible successors and constructors of socialism. Nowadays, well-rounded talents are badly needed and social adaptation ability is an essential factor in students’ competence in labor market. Ideological and political courses, however, can provide students with right guidance and improve students’ capability in social activity and the capacity to resist setbacks. In this way, the students can better adapt to the society.

ABSTRACT : The inhibition of the corrosion of steel in 1 M HCl by pyrazole compounds 5-bromo-N-((3,5-dimethyl-1H-pyrazol-1- yl)pyridine-2-amine (AB8) and 3,5-dibromo-N-((3,5-dimethyl-1H-pyrazol-1-yl)pyridine-2-amine (AB9) has been studied by weight loss, electrochemical polarisation and electrochemical impedance spectroscopy measurements. The results obtained reveal that these compounds are efficient inhibitors. The inhibition efficiency increases with the increase of inhibitor concentration and reached 95 % for AB9 at 10-3 M. Potentiodynamic polarisation studies clearly reveal that the presence of all inhibitors does not change the mechanism of hydrogen evolution and that they act mixed inhibitors. The temperature effect on the corrosion behaviour of steel in 1 M HCl without and with the inhibitors at 10-3M was studied in the temperature range from 308-333K, it allows to determine the several thermodynamic parameters. The inhibitors were adsorbed on the steel surface according ...

ABSTRACT : Dyeing wastewater has caused serious synthetic dyes pollution on both water bodies and soil in China. This study investigated the mechanism of azo dye removal by different vegetative organs of hydroponically grown sunflowers. In all treatments, the percent of dye removal by living organs was higher than corresponding dead organs. The results show that decolorization of Evans blue by tissues of sunflowers was partly attribute to degradation and partly due to sorption. Moreover, the biodegradtion played a greater role than sorption in the dye removal. The biodegradation rate of the dye was estimated. Realistic values of Km and Vmax were estimated by a computer program using non-linear regression treatment and Lineweaver–Burk model. In both methods, the rate of azo dye removal from the aqueous solution by roots was the highest, followed by leaves and stems.

ABSTRACT : Micro porosity and percolation rules by mercury pressure and seepage experiment of Shengli Oilfield low permeability shale cores. Because of the special characteristics of shale bedding structure, resulting in poor correlation with permeability shale hole. Mercury pressure experiment show that interval shale reservoir capillary radius distribution is low, poor sorting pores smaller, rate of permeability contribution. Because the gas slippage effect, generally in low permeability reservoir is nonlinear. The shale reservoir of low permeability, single-phase flow experiments show that shale has obvious characteristics of non-Darcy flow, starting pressure gradient magnitude and permeability, single-phase flow experiments show that shale has obvious characteristics of non-Darcy flow, starting pressure gradient magnitude and permeability negative correlation significantly.

ABSTRACT : The capsaicinoid profile of six different peppers sold in Nigerian markets was determined by Gas ChromatographyMass Spectrometry. The capsaicinoids were extracted from the peppers using methanol as extractant and analyzed without need for derivatization. A total of eight (8) capsaicinoids were identified and quantitated: Capsaicin, Dihydrocapsaicin Dihydrocapsaicin 1, Dihydrocapsaicin 2, Norcapsaicin, Nordihydrocapsaicin 1, Nordihydrocapsaicin 2 and Nornordihydrocapsaicin though, not fully present in all the varieties. Dihydrocapsaicin 1, Dihydrocapsaicin 2, Nordihydrocapsaicin 1, Nordihydrocapsaicin 2 and Nornordihydrocapsaicin are isomers. Seven were identified in the Cameroun pepper variety, six in “Zaria atarugu” and Miango, and five in each of the remaining varieties. In all the peppers analyzed, capsaicin had the highest relative concentration, which ranged from 27.3% in the Cameroun variety to 49.38% in the “Zaria atarugu” variety. The sum of the relative conce...

ABSTRACT: A series of new TTF containing a nitro group were prepared by using a Wittig condensation between a TTF bearing an aldehyde function and an appropriate aromatic phosphonium salt.The reducing power of each new precursor was determined by cyclic voltammetry. Charge transfer complexes of the donors with TCNQ were prepared and characterized. The electrical conductivity of these materials was measured.

ABSTRACT: Incorporation of barley flour (BF) to wheat flour (WF) at 0, 5, 10, 15, 20, 25, 50 and 100% levels was carried out to test the effect on baking quality. BF is characterized by its wealth in soluble fibers and tocols witch have several health benefits. Methods of analysis focused on the determination of physical-chemical criteria, technological and rheological properties. This study has revealed that the addition of BF affected adversely the various criteria and properties studied. In fact, BF increased the ash content and decreased the Zeleny sedimentation value (ZSV). The effect on the ZSV is highly significant (α = 0.01) for level superior than 10 %. A narrow correlation was noticed (r = -0.994). As for rheological properties, the addition of BF resulted in an increase of dough tenacity (P), decrease in baking strength (W) and extensibility (L). The variation of P and L in two opposite directions ended in an imbalance of alveograms (P/L). The tenacity showed significant...
