3Divergent responses of soil carbon and nitrogen pools to short-term nitrogen addition between two plantations in Northeast China显示文摘Nitrogen(N)deposition has a profound influence on forest soil carbon(C)and N pools,but there was no consensus on the responses of different C and N components in different forest types.In this study,a two-year simulated N deposition experiment with four levels of N(NH4NO3)-addition treatments(0,50,100,and 150 kg N/hm^(2)·a)were conducted in Larix gmelinii(LG)and Quercus mongolica(QM)plantation in Northeast China,in order to investigate the C and N pool dynamics under continuously enhanced N deposition.Soil organic carbon(SOC),soil total N(STN)and their active components(readily oxidizable C,ROC;dissolved organic C,DOC;microbial biomass C,MBC,dissolved organic N,DON;microbial biomass N,MBN)of the forest soil were measured monthly from May to October 2017.C and N contents in LG were observed higher than in QM.N addition had no effect on SOC and STN of LG,but significantly increased SOC and STN of QM at low N addition level.Low N addition generally raised active C components(ROC,DOC,and MBC)in both plantations,whereas high N addition did not significantly affect these components,or even decreased ROC in LG soil.Low N addition also increased STN and MBN of QM,while no significant change in STN and MBN of LG was observed.DON was directly affected by N addition and increased significantly with elevated N addition levels.The results indicated that N addition,especially of low rate,might enhance the C sequestration capacity of the forest soils and mitigate climate change.Yedong Li Bo Wang Sen Dou Haoyue Shen Liyong Mei Yang Zhang Ximing Zeng Yaya Zhang Yameng Pei Haoye Ren Shimin Wu 2019International Journal of Agricultural and Biological Engineering2019,12,6:1
4Brugada syndrome:a fatal disease with complex genetic etiologies–still a long way to go显示文摘Brugada syndrome(BrS)is an arrhythmogenic disorder which was first described in 1992.This disease is a channelopathy characterized by ST-segment elevations in the right precordial leads and is susceptible to sudden death.BrS is a fatal disease with gender and age preferences.It occurs mainly in young male subjects with a structurally normal heart and silently progresses to sudden death with no significant symptoms.The prevalence of BrS has been reported in the ranges of 5-20 per 10000 people.The disease is more prevalent in Asia.Nowadays,numerous variations in 23 genes have been linked to BrS since the first gene SCN5A has been associated with BrS in 1998.Not only can clinical specialists apply these discoveries in risk assessment,diagnosis and personal medicine,but also forensic pathologists can make full use of these variations to conduct death cause identification.However,despite the progress in genetics,these associated genes can only account for approximately 35%of the BrS cases while the etiology of the remaining BrS cases is still unexplained.In this review,we discussed the prevalence,the genes associated with BrS and the application of molecular autopsy in forensic pathology.We also summarized the present obstacles,and provided a new insight into the genetic basis of BrS.Yeda Wu Mei Ai Adham Sameer A.Bardeesi Lunwu Xu Jingjing Zheng Da Zheng Kun Yin Qiuping Wu Liyong Zhang Lei Huang Jianding Cheng 2017Forensic Sciences Research2017,2,3:1
5Experimental Research about Denitrification by Box Filler Enhancing MBR Process显示文摘[Objective]The research aimed to study removal effects of the organic matter and N by box filler enhancing MBR process.[Method]By adding box filler into reaction pool of the MBR to treat domestic sewage,removal effects of the organic matter and N by box filler enhancing MBR process were studied.[Result]COD means in effluent were respectively 26.8 and 24.7 mg /L without and with adding filler.Average removal rates of the NH 3-N were respectively 98.44% and 96.37% with and without dosing filler,while average removal rates of the TN were 24.03% and 16.43%,respectively.COD and NH 3-N concentrations in effluent were lower than Level-one A criteria of Discharge Standard of the Pollutant for Municipal Wastewater Treatment Plant(GB18918-2002).NO 3-N was main existence form of the TN in effluent and occupied 98.06%,while NH 3 N and NO 2-N only accounted for 1.22% and 0.72%.Further suggestion for denitrification study was as below.Firstly,the proportion of box filler on volume of the reaction cell should increase to 4%-5%.Secondly,single smaller filler with larger amount of internal fiber ought to be replaced.Thirdly,aeration amount needed to be decreased to right value,making that DO of the MBR reaction cell reduced to 1.5-3.0 mg /L.[Conclusion] The research provided theoretical basis for future engineering practice.Xuning Li Tingquan Pei Huan Liu Zhenye Zhao Liyong Mei 2013Meteorological and Environmental Research2013,4,1:0
6The forensic pathological analysis of sport-related sudden cardiac death in Southern China显示文摘Studies regarding sport-related sudden cardiac death(SCD)mainly focus on competitive ath-letes;similar data are rare in the general population,especially in China.We conducted a retrospective study(from September 1998 to August 2013)to investigate the aetiological distribution and epidemiological features of sport-related SCD in Southern China.Selections of cases are based on details,and two subgroups were established:one was the sport-related SCD group,and the other was the disease-free accident victims group which was matched with the sport-related SCD group in gender,age and year of death.Among the 3770 sudden-death cases,1656 cases were SCD cases.A total of 65 cases(57 males)out of 1656 SCD cases were sport-related.The age range of the 65 sport-related SCD cases was from 12 to 68 years old with a mean(35.92±14.23)years old.Only two of these cases were competitive athletes.The most common circumstances of the 65 sport-related SCD cases were heavy physical labour(46.15%)and running(30.77%).The three leading forensic diag-noses were the coronary atherosclerotic disease(CAD,28 cases),cardiomyopathy(CM,14 cases)and sudden unexplained death(7 cases).CM was the most common forensic diagno-sis in those?35 years old,while CAD was the most common one in those>35 years old.Left anterior descending in which atherosclerotic plaques was most commonly found was the principal artery branch associated with sport-related SCD.There was a statistically signifi-cant difference in the weight of hearts between the 65 sport-related SCD cases and 65 dis-eases-free accidental cases.This study highlights the need to attract public attention to sport-related SCD and to issue a prevention strategy to the public,and to make the SCD-related genetic sequencing a routine tool in both forensic pathological examination and clinic screening.Yeda Wu Mei Ai Adham Sameer A.Bardeesi Liyong Zhang Qiuping Wu Kun Yin Jingjing Zheng Da Zheng Lei Huang Lunwu Xu Jianding Cheng 2020Forensic Sciences Research2020,5,1:0
7Application Study of Trajectory Plume Model in Atmospheric Environmental Impact Assessment显示文摘[Objective]The research aimed to study application of the trajectory plume model in atmospheric environmental impact assessment. [Method]Trajectory plume model was used to retrospectively evaluate regional atmospheric improvement degree by fuel gas desulfurization project in Mawan Power Plant of Shenzhen.
