The extraction performances of various extractants and diluents were compared and the apparent basicity ofN235 （a mixture of tertiary amines） in various diluents was determined. The best results were obtained using N235 and isoamyl alcohol as the extractant and diluent, respectively. The yield of HC1 from the coupled extraction was 75% with this extraction system. The mechanisms for the removal of HC1 in both the direct and coupled extractions were investigated. For the coupled extraction, the formation of an RaNHC1 ion-pair complex was involved in the HC1 removal. For the direct extraction, the mechanism involved the formation of hydrogen bonds at high concentrations of HC1.展开更多

The results showed that the agronomic traits and biomass of flue-cured tobacco in the three treatments were higher than that of the control group,and the mixed application of different organic fertilizers made from distiller＇s grains and compound fertilizer could promote the growth and development of flue-cured tobacco significantly.展开更多

Without contribution of additional resources, water will then be likely to be done increasingly rare. The solar still is a small production system, yielding on average 2-5 L/day. In this study we propose a solar distiller assisted by a heat pump. The design of this distiller uses for the evaporation of water and its condensation two phenomena are studied Simple Solar Distiller （SSD） and Simple Solar Still Distiller Hybrid with heat Pump （SSDHP）. The performance is less than 2 L/mVday and a performance of 30% for the SSD. But the SSDHP is 12 L/m2/day, the energetic efficiency reaches 90%.展开更多

The objective of this study was to investigate effects of liquid feeding high levels of corn condensed distiller＇s solubles（CCDS） and whole stillage（CWS） on growth performance, carcass characteristics, belly firmness and meat sensory traits of pigs.Methods： A total of 256 pigs were blocked by sex and initial BW（13.5 ± 2.5 kg）, and pens of pigs（8 pigs/pen） were randomly allocated to 1 of 4 dietary treatments（8 pens/treatment）： 1） corn-soybean meal based diet as control, 2） 25%CWS ＋ 5% CCDS, 3） 19.5% CWS ＋ 10.5% CCDS, and 4） 19.5, 26, and 32.5% CWS ＋ 10.5, 14, and 17.5% CCDS in phases 1（28 d）, 2（38 d）, and 3（60 d）, respectively. Inclusion levels of CCDS and CWS for Treatments 1, 2, and 3 were fixed during all the three phases of the experiment. Inclusion levels of CWS and CCDS were on 88% dry matter basis. The liquid feeding system delivered feed from the mixing tank to feed troughs by high-pressure air, had sensors inside feed troughs, and recorded daily feed intake on the basis of a reference feed intake curve. The pigs were fed 5 to 10 times per day with increasing frequency during the experiment.Results： Control pigs had greater（P 0.10） dressing percentage, loin muscle depth, and lean percentage were observed among the four treatments. Inclusion of CWS and CCDS reduced（P 0.10） the overall like,flavor, tenderness and juiciness of loin chops when compared with the control group.Conclusion： In conclusion, our results indicate that including 30–50% of a mixture of whole stillage and condensed distiller＇s solubles in the growing-finishing diets may reduce growth performance, carcass weight and belly firmness, but does not affect pork sensory traits.展开更多

The results showed that when 60% of humic acid was added to the distiller s grain substrate made from coarse distiller s grains, fine distiller s grains, perlite and vermiculite, both the pH and electrical conductivity decreased significantly and were similar to that of the conventional substrate. Moreover, the emergence rate of tobacco seedlings, the rate of strong tobacco seedlings, leaf number, stem height, root growth and quality of tobacco seedlings were good.展开更多
