| 1 | Effects of benzoic acid(Vevo Vitall) on the performance and jejunal digestive physiology in young pigs显示文摘Background: As a organic acid, benzoic acid has become one of the most important alternatives for antibiotics,and its beneficial effect on performance in animals has been proven for a decade. However, knowledge of the effects of benzoic acid on jejunal digestive physiology, especially the antioxidant capacity and mucosal glucagon-like peptide2(GLP-2) concentrations is lacking.Methods: A total of 20 barrows [Duroc ×(Yorkshire × Landrace)] with an average body weight(BW) of 18.75 ± 0.2 kg were used in a 14-d trial to determine the potential mechanisms of benzoic acid supplementation on the performance,nutrient digestibility and jejunal digestive physiology in young pigs. All pigs were randomly allotted to 1 of 2 diets supplemented with 0 or 5000 mg/kg benzoic acid.Results: Relative to the control, benzoic acid supplementation increased the average daily feed intake(ADFI), and average daily gain(ADG) in young pigs(P < 0.05), improved the apparent total tract digestibility of dry matter(DM),crude protein(CP), ether extract(EE), gross energy(GE) and crude ash(P < 0.05), and enhanced the activities of trypsin,lipase and amylase in the jejunum(P < 0.05). Similarly, relative to the control, supplementing benzoic acid in the diet resulted in a trend to reduce the p H values of the digesta(P = 0.06), decreased crypt depth and increased the villus height to crypt depth ratio(P < 0.05) in the jejunum of pigs. Finally, benzoic acid supplementation increased the mR NA expression and concentration of glucagon-like peptide 2 and the activities of glutathione peroxidase and superoxide dismutase in the jejunal mucosa of young pigs(P < 0.05).Conclusions: In conclusion, supplementation with 5000 mg/kg benzoic acid improved the performance of young pigs through promoting nutrient digestion, improving jejunal antioxidant capacity, and maintaining the jejunal morphology in young pigs. | Hui Diao Zengbing Gao Bing Yu Ping Zheng Jun He Jie Yu Zhiqing Huang Daiwen Chen Xiangbing Mao | 2017 | Journal of Animal Science and Biotechnology2017，8，1： | 10 |
| 2 | Effects of long-term fertilization with different substitution ratios of organic fertilizer on paddy soil显示文摘In recent years,the abuse of chemical fertilizers has caused numerous environmental problems,such as soil acidification and compaction.Replacing chemical fertilizers with organic fertilizers can effectively alleviate these problems.However,the effects of alternative organic fertilizers remain unclear.To explore the effects of organic fertilizer substitution on rice yield and paddy soil physicochemical properties and bacterial community structure,we conducted a 5-year experiment using different proportions of organic fertilizer substitution in a double-cropping rice field in Jiangxi,China.Our results showed that replacing chemical fertilizers with organic fertilizers can reduce soil acidification,increase soil organic matter content,nutrient contents,and enzyme activities,improve soil physicochemical properties and microbial community,and enhance soil metabolism.Appropriate organic substitution also had positive effects on rice production.These findings enhance our understanding of the effects of different alternative organic fertilization methods and have important theoretical significance for the promotion of the use of organic fertilizers in the future. | Weifeng SONG Aiping SHU Jiai LIU Wenchong SHI Mingcong LI Wenxue ZHANG Zuzhang LI Guangrong LIU Fusheng YUAN Shuxin ZHANG Zengbing LIU Zheng GAO | 2022 | Pedosphere2022，32，4： | 7 |
| 3 | Long time evolution of a spin interacting with a spin bath in arbitrary magnetic field显示文摘We introduce a completely different method to calculate the evolution of a spin interacting with a sufficient large spin bath,especially suitable for treating the central spin model in a quantum dot(QD).With only an approximation on the envelope of central spin,the symmetry can be exploited to reduce a huge Hilbert space which cannot be calculated with computers to many small ones which can be solved exactly.This method can be used to calculate spin-bath evolution for a spin bath containing many(say,1000)spins,without a perturbative limit such as strong magnetic field condition,and works for long-time regime with sufficient accuracy.As the spin-bath evolution can be calculated for a wide range of time and magnetic field,an optimal dynamic of spin flip-flop can be found,and more sophisticated approaches to achieve extremely high polarization of nuclear spins in a QD could be developed. | ZHAO YuKang ZHAO MeiSheng CHEN ZengBing | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，7： | 2 |

| 16 | The organization and traffic engineering of a quantum cryptography network显示文摘How many users can a quantum cryptography network support when certain services are demanded? The answer to this question depends on three factors:the speed of quantum key distribution,the organization and traffic engineering of the quantum cryptography network,and the engineering of services.In this article we focus on the second factor which is lacked in the literature to our knowledge but in urgent need for constructing an optimized large-scale quantum cryptography network.In order to provide an overall understanding about a quantum cryptography network,we also briefly introduce the characteristics of quantum cryptography and service engineering. | ZHAO YuKang ZHAO MeiSheng ZHAO Yong CHEN ZengBing | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，9： | 0 |
| 17 | Effect of isotope diffusion in solids on isochron ages under -pper mantle conditions显示文摘DODSON presented the concepts of closure temperature (T_c), transitional temperature range (T_h—T_l) and T_l<T_c<T_h in geochronology when he developed the theory of cooling ages. For the mineralogical system in the earth crust, geochronometers work usually under cooling conditions of T<T_c. But in the earth mantle at T>T_l, the effect of matter transfer by diffusion on radiometric dating is not negligible in the transitional temperature range | ZHI Xiachen, CHEN Zengbing, ZHANG Xuehua and ZHENG Yongfei1.
