| 1 | Fermented soybean meal improves the growth performance, nutrient digestibility, and microbial flora in piglets显示文摘In order to increase nutritive values of soybean meal(SBM), 3 species of microbes were used to ferment SBM. Through a 3 x 3 orthogonal design and parameter measurements of soybean peptide and antinutritional factor contents in the fermented soybean meal(FSBM), it was estimated that the best microbial proportion of Bacillus subtilis, Hansenula anomala and Lactobacillus casei was 2:1:2 for SBM fermentation(P < 0.05). The further piglet feeding experiment showed that 10% FSBM substitute for SBM had no significant effect on growth performance of suckling piglets(d 7-28)(P> 0.05). However, newlyweaned piglets(d 28-38) fed 10% FSBM and different levels of plasma protein obtained higher average daily gain(ADG) and feed conversion ratio(FCR), compared with those without FSBM but with 6% plasma protein(P < 0.05). Piglets(d 38-68) fed diets supplemented with FSBM and soybean protein concentrate(SBPC) at 3.75% and 7.5% respectively increased nutrient digestibility,fecal enzyme activity and lactic acid bacteria counts, and decreased fecal Escherichia coli counts(P < 0.05), compared with the control. These data indicated that FSBM had positive effects on nutrient digestibility and fecal microflora for piglets. | Lin Yuan Juan Chang Qingqiang Yin Min Lu Yuanran Di Ping Wang Zhixiang Wang Erzhu Wang Fushan Lu | 2017 | Animal Nutrition2017，，1： | 31 |
| 2 | Highly selective oxidation of amines to imines by Mn2O3 catalyst under eco-friendly conditions显示文摘Enhancing the selectivity of imines for the oxidative self-coupling of primary amines was found to be challenging in the heterogeneous catalysis.Three different manganese oxides(M-3,M-4,M-5) were synthesized by controlling the calcination temperature using a simple template-free oxalate route.The prepared manganese oxides were systematically characterized using XRD,N2 sorption,SEM,TEM,XPS,H2-TPR techniques.M-4 gave 96.2% selectivity of imine at 100% conversion of benzylamine,which was far more superior than other existing protocols.Mn^3+/Mn^4+ ratio was found to affect the selectivity of the imines.The probable reaction pathway for amines oxidation catalyzed by manganese oxides was proposed for the first time. | Fushan Chen Tao Yang Songlin Zhao Taotao Jiang Lu Yu Houfeng Xiong Chuankun Guo Yufang Rao Yan Liu Liu Liu Jian Zhou Pengxiang Tu Jun Ni Qunfeng Zhang Xiaonian Li | 2019 | Chinese Chemical Letters2019，30，12： | 1 |
| 3 | Influences of the Fresh Air Volume on the Removal of Cough-Released Droplets in a Passenger Car of a High-Speed Train Using CFD显示文摘The spread and removal of pollution sources,namely,cough-released droplets in three different areas(front,middle,and rear areas)of a fully-loaded passenger car in a high-speed train under different fresh air flow volume were studied using computational fluid dynamics(CFD)method.In addition,the structure of indoor flow fields was also analysed.The results show that the large eddies are more stable and flow faster in the air supply under Mode 2(fresh air volume:2200m3/h)compared to Mode 1(fresh air volume:1100m3/h).By analysing the spreading process of droplets sprayed at different locations in the passenger car and with different particle sizes,the removal trends for droplets are found to be similar under the two air supply modes.However,when increasing the fresh air flow volume,the droplets in the middle and front areas of the passenger car are removed faster.When the droplets had dispersed for 60s,Mode 2 exhibited a removal rate approximately 1%–3%higher than Mode 1 for small and medium-sized droplets with diameters of 10 and 50μm.While those in the rear area,the situation is reversed,with Mode 1 slightly surpassing Mode 2 by 1%–3%.For large droplets with a diameter of 100μm,both modes achieved a removal rate of over 96%in all three regions at the 60 s.The results can provide guidance for air supply modes of passenger cars of high-speed trains,thus suppressing the spread of virus-carrying droplets and reducing the risk of viral infection among passengers. | Jun Xu Kai Bi Yibin Lu TiantianWang Hang Zhang Zeyuan Zheng Fushan Shi Yaxin Zheng Xiaoying Li Jingping Yang | 2024 | Computer Modeling in Engineering & Sciences2024，138，3： | 0 |
