| 1 | Enhancement of High Energy Electron Fluxes and Variation of Atmospheric Electric Field in the Antarctic Region显示文摘High-energy electron precipitation in the high latitude regions enhances the ionization of the atmosphere,and subsequently increases the atmospheric conductivities and the vertical electric field of the atmosphere near the ground as well.The High-Energy Electron Flux(HEEF) data measured by the Fengyun-3 meteorological satellite are analyzed together with the data of nearsurface atmospheric vertical electric field measured at the Russian Vostok Station.Three HEEF enhancements are identified and it is shown that when the HEEF increases to a certain level,the local atmospheric vertical electric field near the ground can increase substantially than usual.The response time of the electric field to HEEF enhancement is about 3.7 to 4 days. | LI Renkang CHEN Tao LUO Jing ZHOU Limin HE Zhaohai WANG Chunqin SUN Yueqiang | 2016 | 空间科学学报2016,36,1: | 8 |
| 2 | Milk selenium content and speciation in response to supranutritional selenium yeast supplementation in cows显示文摘The effects of selenium(Se)yeast supplementation on performance,blood biochemical and antioxidant parameters,and milk Se content and speciation were evaluated.Thirty-six mid-lactation Holstein dairy cows were randomly assigned to 1 of 3 treatments:1)control(basal diet containing Se at 0.11 mg/kg DM),2)basal diet+0.5 mg supplemental Se/kg DM(SY-0.5),and 3)basal diet+5 mg supplemental Se/kg DM(SY-5).Selenium was supplemented as Se yeast.The trial consisted of a 1-week pretrial period and an 8-week experimental period.Milk somatic cell score decreased with SY-5 supplementation(P<0.05),but other performance parameters were not affected(P>0.05).The serum Se concentration increased with the increasing levels of Se yeast supplementation(P<0.05),however,blood biochemical parameters showed few treatment effects.The antioxidant capacity of dairy cows was improved with Se yeast supplementation reflected in increased serum glutathione peroxidase activity(P<0.05)and total antioxidant capacity(P=0.08),and decreased malondialdehyde concentration(P<0.05).Milk total Se concentration increased with Se dose(P<0.05).Also,the selenomethionine concentration increased with Se dose from 13.0±0.7 pg/kg in control to 33.1±2.1 pg/kg in SY-0.5 and 530.4±17.5 pg/kg in SY-5 cows(P<0.05).Similarly,selenocystine concentration increased from 15.6±0.9μg/kg in control and 18.9±1.1 pg/kg in SY-0.5 to 22.2±1.5 pg/kg in SY-5 cows(P<0.05).In conclusion,Se yeast is a good organic Se source to produce Se-enriched cow milk with increased Se species including selenomethionine and selenocystine.The results can provide useful information on milk Se species when a high dose Se yeast was supplemented in the cow diet. | Lingling Sun Gentao Liu Dongmei Xu Zhaohai Wu Lu Ma Sanz-Fernandez M.Victoria Lance H.Baumgard Dengpan Bu | 2021 | Animal Nutrition2021,,4: | 6 |
| 3 | Effects of dissolved organic matter from sewage sludge on sorption of tetrabromobisphenol A by soils显示文摘Sorption of tetrabromobisphenol A (TBBPA) by soil influences its fate and transport in the environment. The presence of dissolved organic matter (DOM) may complicate the sorption process in soil. The effects of DOM from sewage sludge on TBBPA sorption by three soils were investigated using batch equilibration experiments in the study. DOM was observed to be sorbed on the soils and the isotherms could be fitted by the Langmuir model. The effects of DOM on TBBPA sorption were dependent on the characteristics of soils and the concentrations of DOM present. TBBPA sorption by Henan (HN) soil (sandy loam) and Liaoning (LN) soil (loamy clay) was promoted in the presence of DOM at low concentration ( 90 mg organic carbon (OC)/L), and the sorption was promoted by HN soil and inhibited by LN soil at DOM added concentration of 180 mg OC/L. TBBPA sorption by Guangxi (GX) soil (silt loam) was always inhibited in the presence of DOM. It was also found that the amount of TBBPA sorbed decreased with the increase in the solution pH value in the absence of DOM. The influencing mechanisms of DOM on the sorption of TBBPA by soils were also discussed. | Zhaohai SUN Hongxia YU | 2008 | Journal of Environmental Sciences2008,20,9: | 6 |
| 4 | Review: Utilization of yeast of Saccharomyces cerevisiae origin in artificially raised calves显示文摘Yeast of Saccharomyces cerevisiae(SCY) origin has over long time been incorporated into domestic animal diets. In calves, several products have offered improved performance and health. Although several types of research have been completed, the mode of action of SCY is not clear in calves. Under this review, we have highlighted the works available in the literature on the use of SCY in calves performance, health, immunity, and the gut environment. Both active live yeast and yeast culture have positive effects on growth, rumen, small intestines, immunity and general health of the calf. Specifically, SCY can improve DMI, growth, feed efficiency and reduce diarrhea in calves. Furthermore, subtle improvements are seen in rumen fermentation(increased butyrate production) and rumen papillae growth. These positive results are, however, more pronounced in calves that are under stress or exposed to significant levels of disease-causing agents. There is a need for further research in areas such as gut morphology, gut microbiology and immunity using latest molecular methods to fully understand how SCY helps the growth and development of calves. | Gibson M.Alugongo Jianxin Xiao Zhaohai Wu Shengli Li Yajing Wang Zhijun Cao | 2017 | Journal of Animal Science and Biotechnology2017,8,3: | 6 |
| 5 | CH_4 and N_2O emissions from double-rice cropping system as affected by Chinese milk vetch and straw incorporation in southern China显示文摘Chinese milk vetch(CMV) and rice straw(RS)were incorporated into soil to substitute for synthetic N fertilizers and to maintain soil fertility. However, little is known about the integrated impacts of CMV and RS incorporation on CH_4 and N_2O emissions in double-rice cropping systems in southern China. A field experiment was conducted to estimate the integrated impacts of CMV and RS incorporation in the early-and late-rice seasons on CH_4 and N_2O emissions. All treatments received uniform N inputs, 6%–37% of which was replaced by CMV and RS crop residue. CMV and/or RS incorporation produced equivalent or slightly more grain yield, while reducing N2 O emissions by 3%–43%. However, both CMV and RS incorporation increased CH_4 emissions. Annual CH_4 emissions ranged from 321 to 614 kg·hm^(–2)from CMV and RS amendment treatments, which were 1.5–2.9 times higher than that from synthetic N. Compared with single synthetic N fertilizer, incorporation of CMV and/or RS increased GWP and yield-scaled GWP by 45%–164% and45%–153%, respectively. Our results demonstrate CMV and RS amendments replacing N fertilizer, maintained stable yield, mitigated N_2O emission, but enhanced CH_4 emission. Further study is needed on crop residue management in double-cropping rice systems. | Heshui XU Dengyun LI Bo ZHU Kai ZHANG Yadong YANG Chen WANG Ying JIANG Zhaohai ZENG | 2017 | Frontiers of Agricultural Science and Engineering2017,4,1: | 5 |
| 6 | Strategies to reduce nutrient pollution from manure management in China显示文摘As the demand for livestock products continues to increase in China,so too does the challenge of managing increasing quantities of manure.Urgent action is needed to control point source(housing,storage and processing)and diffuse(field application)pollution and improve the utilization of manure nutrients and organic matter.Here,we review strategies to improve management at each stage of the manure management chain and at different scales.Many strategies require infrastructure investment,e.g.,for containment of all manure fractions.Engineering solutions are needed to develop advanced composting systems with lower environmental footprints and design more efficient nutrient stripping technologies.At the field-scale,there is an urgent need to develop a manure nutrient recommendation system that accounts for the range of manure types,cropping systems,soils and climates throughout China.At the regional scale,coordinated planning is necessary to promote recoupling of livestock and cropping systems,and reduce nutrient accumulation in regions with little available landbank,while minimizing the risk of pollution swapping from one region to another.A range of stakeholders are needed to support the step change and innovation required to improve manure management,reduce reliance on inorganic fertilizers,and generate new business opportunities. | David R.CHADWICK John R.WILLIAMS Yuelai LU Lin MA Zhaohai BAI Yong HOU Xinping CHEN Thomas H.MISSELBROOK | 2020 | Frontiers of Agricultural Science and Engineering2020,7,1: | 4 |
| 7 | The diazotrophic community in oat rhizosphere: effects of legume intercropping and crop growth stage显示文摘In this study, the abundance, diversity and structure of the diazotrophic community in oat rhizosphere soil in three cropping systems and at two oat growth stages were investigated using real-time PCR and Illumina MiSeq sequencing. The nifH gene abundance in oat-soybean intercropping (OSO) and oat-mungbean intercropping (OMO) was significantly greater than that in sole oat (O), but the nifH gene abundance significantly decreased at the later stage in all the treatments. Alpha diversity indices in OSO and OMO were higher at the heading stage, but lower at the maturity stage than that in O. Bradyrhizobium and Skermanella were the dominant genera identified in all samples, with an average proportion of 35.8% and 12.4%, respectively. The proportion of dominant genera showed significant differences and varied with cropping system and growth stage. Principal component analysis showed that growth stage had a stronger effect than intercropping on the diazotrophic community structure. However, Mantel test and redundancy analysis showed there was no environmental factor significantly correlated to the diazotrophic community structure. Our results demonstrate that intercropping had a weaker effect than growth stage on the abundance, diversity and structure of the diazotrophic community in oat rhizosphere soil. | Yadong YANG Xiaomin FENG Yuegao HU Zhaohai ZENG | 2019 | Frontiers of Agricultural Science and Engineering2019,6,2: | 3 |
| 8 | China needs long-term solutions for African Swine Fever显示文摘African Swine Fever(ASF)has received a lot of public concerns in and outside of China(1)Currently,more than 1 million head of pigs have been culled,and the stocking number of fattening pigs and sows has been reported reduced by more than 20%(Fig.1a,b),and the price of pork has been increased by around 30%compared with the same period in 2018(Fig.1c).ASF in China has also had a significant impact on the world meat market,due to its huge contribution to global pig production. | Jun Zhao Zhaohai Bai Lin Ma | 2019 | Science Bulletin2019,64,20: | 3 |
| 9 | Performance of common buckwheat(Fagopyrum esculentum M.) supplied with selenite or selenate for selenium biofortification in northeastern China显示文摘Selenium(Se)deficiency commonly occurs in soils of northeastern China and leads to insufficient Se intake by humans.A two-year field study of Se biofortification of common buckwheat supplied with 40 g Se ha^(-1)as selenite(Se(IV)),selenate(Se(VI)),or a combination(1/2 Se(IV+VI))was performed to investigate Se accumulation and translocation in plants and determine the effects of different forms of Se on the grain yield,biomass production,and Se use efficiency of plants and seeds.Se application increased seed Se concentrations to 47.1–265.1μg kg^(-1).Seed Se concentrations following Se(VI)or 1/2 Se(IV+VI)treatment exceeded 100μg kg^(-1),an amount suitable for crop Se biofortification.Se concentration in shoots and roots decreased with plant development,and Se translocation from root to shoot in Se(IV)-treated plants was lower than that in plants treated with 1/2 Se(IV+VI)and Se(VI).Both grain yield and biomass production increased under 1/2 Se(IV+VI)treatment,with grain yields reaching 1663.8 and 1558.5 kg ha^(-1)in 2015 and 2016,respectively,reflecting increases of 11.0% and 10.3% over those without Se application.The Se use efficiency of seeds and plants under Se(VI)treatment was significantly higher than those under 1/2 Se(IV+VI)and Se(IV)treatments.Thus,application of selenate could result in higher Se accumulation in buckwheat seeds than application of the other Se sources,but the combined application of selenate and selenite might be an alternative approach for improving buckwheat grain yield by Se biofortification in northeastern China. | Ying Jiang Xiaomin Feng Yadong Yang Xiangxue Qi Yongfeng Ren Youhui Gao Weidong Liu Yuegao Hu Zhaohai Zeng | 2018 | The Crop Journal2018,6,4: | 3 |
| 10 | Dietary Bacillus spp.enhanced growth and disease resistance of weaned pigs by modulating intestinal microbiota and systemic immunity显示文摘Background:Previous research has shown that dietary supplementation of Bacillus spp.probiotics exerts beneficial effects on animals’growth.However,limited studies have evaluated the efficacy of Bacillus spp.on weaned pigs and their effects on host gut health and microbiome,and systemic immunity using a disease challenge model.The objective of this experiment was to investigate the effects of two Bacillus spp.strains(Bacillus subtilis DSM 32540 and Bacillus pumilus DSM 32539)on growth performance,diarrhea,intestinal health,microbiome,and systemic immunity of weaned pigs experimentally infected with an enterotoxigenic Escherichia coli(ETEC).Results:Pigs in PRO1(Bacillus subtilis DSM 32540)had greater(P<0.05)body weight on d 7 and 14 PI,greater(P<0.05)ADG from d 0 to 7 and d 7 to 14 PI,compared with pigs in CON(Control).Pigs in PRO1 had milder(P<0.05)diarrhea on d 2 and 3 PI compared with pigs in CON.However,no differences were observed in growth performance and diarrhea score between PRO2(Bacillus pumilus DSM 32539)and CON groups.Supplementation of PRO1 decreased(P<0.05)lymphocyte counts on d 7 and 14 PI,compared with CON.Supplementation of PRO1 and PRO2 both reduced(P<0.05)total coliforms in mesenteric lymph nodes on d 21 PI.Pigs in PRO2 had greater(P<0.05)goblet cell number and sulfomucin percentage in duodenal villi and greater(P<0.05)sialomucin percentage in jejunal villi than pigs in CON.Supplementation of PRO1 up-regulated(P<0.05)MUC2 gene expression in jejunal mucosa and reduced(P<0.05)PTGS-2 and IL1B gene expression in ileal mucosa on d 21 PI,compared with CON.Pigs in PRO1 had reduced(P<0.05)relative abundance of families Lachnospiraceae,Peptostreptococcaceae and Pasteurellaceae in the ileum.Conclusions:Supplementation of Bacillus subtilis DSM 32540 improved growth performance,alleviated diarrhea severity,enhanced gut health,and reduced systemic inflammation of weaned pigs infected with ETEC F18.Although Bacillus pumilus DSM 32539 was able to alleviate systemic inflammation,it had limited impacts on growth performance and severity of diarrhea of ETEC F18 challenged weaned pigs. | Yijie He Cynthia Jinno Kwangwook Kim Zhaohai Wu Bie Tan Xunde Li Rose Whelan Yanhong Liu | 2021 | Journal of Animal Science and Biotechnology2021,12,2: | 2 |
| 11 | China’s low-emission pathways toward climate-neutral livestock production for animal-derived foods显示文摘Animal-derived food production accounts for 19%of global anthropogenic greenhouse gas(GHG)emissions.Diet followed in China is ranked as lowcarbon emitting(i.e.,0.21 t CO_(2-)eq per capita in 2018,ranking at 145^(th) of 168 countries)due to the low average animal-derived food consumption rate,and preferential consumption of animal-derived foods with lower GHG emissions(i.e.,pork and eggs versus beef and milk). | Rong Wang Zhaohai Bai Jinfeng Chang Qiushuang Li Alexander N.Hristov Pete Smith Yulong Yin Zhiliang Tan Min Wang | 2022 | The Innovation2022,3,2: | 2 |
| 12 | A Software-Only Method for Measuring Execution Times显示文摘Requirements for embedded systems are very stringent and sometimes conflicting. The Traditional software-only methods (TSOMs) for measuring the execution time of real-time code are easy to use and low in cost, but provide low resolution and great overhead. The two drawbacks degrade accuracy of analyzing real-time performance of embedded systems. Because only the indispensable resources are employed, side effects of the drawbacks on analysis results are even more. So TSOMs don't qualify for accurately analyzing real-time performance, such as identifying whether a task set is schedulable. In order to overcome the two main obstacles, this paper presents a software-only method, which takes the information fusion idea of multi-source data to improve accuracy of the measurements, while it reserves the good features owned by traditional ones. This paper uses the measurements got by a hardware method as criterion to evaluate the softwareonly method experimentally. And the result shows the most deviation score is about 1%. | WANGJiyong ZHAOHai LINTao WANGJindong HANGuangjie | 2004 | Chinese Journal of Electronics2004,13,3: | 1 |
