1鸡粪中高温厌氧甲烷发酵产气潜能与动力学特性显示文摘采用富含氮素的鸡粪为原料,包括原料鸡粪、鸡粪固相部分和鸡粪液相部分,选取以鸡粪为原料连续稳定运行超过90d的中高温厌氧反应器新鲜出料为接种污泥,在中温(35℃)和高温(55℃)条件下开展动力学和产甲烷潜能试验.采用Gompertz模型、一级动力学模型和两阶段模型对鸡粪中高温累积产甲烷量进行拟合.结果表明,鸡粪中高温甲烷发酵均呈现明显的快速产气期和慢速产气期两阶段特征,快速产气期的动力学常数K1分别为0.4174和0.2104d^(-1),快速产气分别在4.5和6.5d结束,快速产气量占到总产气量的69%和58%.原料鸡粪和液相部分的中温发酵动力学常数(K1)分别为0.4177和0.2330d^(-1),均高于高温的0.1721,0.2214d^(-1),发酵产气速率较快.鸡粪固相部分中温发酵的动力学常数为0.1960d^(-1),低于液相中温发酵的0.2330d^(-1)和固相高温的0.2310d^(-1),中温条件下,水解过程是限制鸡粪甲烷发酵速率的主要因素之一.鸡粪固体和鸡粪液体高温发酵的动力学常数K分别为0.2310,0.22214d^(-1),鸡粪固体发酵产甲烷的速率快于液相部分,水解过程不是限制鸡粪高温发酵产甲烷速率的最主要因素.产甲烷潜能试验表明鸡粪在中温和高温下产甲烷潜能分别为212,177m L/g TS.因此,仅从发酵效率的角度考虑,鸡粪中温发酵比高温发酵的产甲烷潜能更高,产甲烷速率更快.乔玮 毕少杰 尹冬敏 姜萌萌 Dalal E.Algapani 董仁杰 2018中国环境科学2018,38,1:16
2餐厨垃圾与污泥厌氧发酵产气动力学特性研究显示文摘对餐厨垃圾、污水厂污泥以及餐厨垃圾与污泥混合甲烷发酵的产气能力与动力学特性进行了实验分析,餐厨垃圾在中温和高温发酵的产甲烷潜能分别是400和426 m L CH_4·g VS-1,经过120℃、20 min蒸煮除油后的餐厨垃圾在中温和高温发酵的产甲烷潜能分别是418和531 m L CH4·g VS^(-1)。经Gompertz模型计算,除油后餐厨垃圾的最大产甲烷速率Rmax比除油前提高了49.8%(中温)和19.0%(高温),但餐厨垃圾中固体有机物的产甲烷速率变化不明显。在餐厨垃圾机械破碎匀浆过程中,部分固体有机物被液化,中、高温发酵产气过程的一级动力学呈现两阶段特征,液相有机物在中温发酵的产甲烷速率(速率常数k=0.195 5 d^(-1))略快于高温(k=0.154 3 d^(-1));而固体有机物在高温条件下的产甲烷速率(k=0.080 4 d^(-1))快于中温(k=0.038 8 d^(-1))。除油后餐厨垃圾中的固体有机物和污泥高温发酵的产甲烷速率也快于中温发酵,表明高温发酵有利于提高固体有机物的产气速率。污泥的产气潜能较低,产气速率慢,与餐厨垃圾共发酵有助于调节碱度和防止发酵体系的酸化。苏敏 乔玮 ALGAPANI Dalal WANDERA Simon GOGLIO Andrea ADANI Fabrizio 陈理 肖政 魏泉源 董仁杰 2016新能源进展2016,,1:8
3餐厨垃圾和秸秆混合连续高温甲烷发酵研究显示文摘以餐厨垃圾和玉米秸秆(按TS1:1混合)为原料,开展了200d的连续高温发酵和40d批次产甲烷潜能与动力学实验,进料TS浓度8%,以水力停留时间15,10,8,5d的梯度变化逐级增加容积负荷.连续实验发现,在水利停留时间为5d时达到了系统酸化的极限负荷16gVS/(L·d),通过及时停止进料和投碱控制pH值,一周内有机酸浓度由4.73g/L降低到1.02g/L.当OLR为10gVS/(L·d)时,TS去除率和甲烷转化率分别为55.6%和64.5%.批次实验发现,餐厨垃圾、秸秆和混合原料的产甲烷潜能分别为448,221,268mLCH_4/gVS,最大产甲烷速率常数(K)为63,45,41mLCH_4/(g VS·d).通过连续和批次实验分别获得了混合原料高温甲烷发酵的工艺参数和动力学特征,为餐厨垃圾和秸秆能源化利用提供了一个有效途径.刘月玲 乔玮 Serena CROCE Dalal ALGAPANI 严新荣 赵婧 苏敏 Fabrizio ADANI 董仁杰 2017中国环境科学2017,37,6:7

5Ayurvedic drug induced liver injury显示文摘Drug induced liver injury is responsible for 50% of acute liver failure in developed countries. Ayurvedic and homeopathic medicine have been linked to liver injury. This case describes the first documented case of Punarnava mandur and Kanchnar guggulu causing drug induced liver injury. Drug induced liver injury may be difficult to diagnosis, but use of multi-modalities tools including the ACG algorithms, causative assessment scales, histological findings, and imaging, is recommended. Advanced imaging, such as magnetic resonance cholangiopancreatography, may possibly have a greater role than previously reported in literature.Kunal K Dalal Thomas Holdbrook Steven R Peikin 2017World Journal of Hepatology2017,9,31:2

9Implementation and Evaluation of Dynamically Weighted Low Complexity Fair Queuing(DWLC-FQ) Algorithm for Packet Scheduling in WiMAX Networks显示文摘Services provided by internet need guaranteed network performance. Efficient packet queuing and scheduling schemes play key role in achieving this. Internet engineering task force(IETF) has proposed Differentiated Services(Diff Serv) architecture for IP network which is based on classifying packets in to different service classes and scheduling them. Scheduling schemes of today's wireless broadband networks work on service differentiation. In this paper, we present a novel packet queue scheduling algorithm called dynamically weighted low complexity fair queuing(DWLC-FQ) which is an improvement over weighted fair queuing(WFQ) and worstcase fair weighted fair queuing+(WF2Q+). The proposed algorithm incorporates dynamic weight adjustment mechanism to cope with dynamics of data traffic such as burst and overload. It also reduces complexity associated with virtual time update and hence makes it suitable for high speed networks. Simulation results of proposed packet scheduling scheme demonstrate improvement in delay and drop rate performance for constant bit rate and video applications with very little or negligible impact on fairness.Zuber Patel Upena Dalal 2016China Communications2016,13,5:2
10Structurally Interesting Diarymethane Derivatives from Securidaca inappendiculata显示文摘Securines A—E,three dimeric diarymethane derivatives(1-3)and two enantiomeric diarymethane derivative monomers(4 and 5),were isolated and characterized from the medicinal plant Securidaca inappendiculata.Compounds 1 and 2 are a pair of enantiomeric diarymethane derivative dimers,and compound 3 is a mesomeric diarymethane derivative dimer.Their structures were determined by a combination of spectroscopic data,X-ray crystallography,electronic circular dichroism(ECD)analysis,and computational ECD calculations.Dimeric compounds 1-3 showed moderate antiplasmodial activities with IC50 values of 0.9,1.4,and 1.5μM,respectively.Bin Zhou Yan Wu Lishe Gan Seema Dalal Maria B.Cassera Jianmin Yue 2020Chinese Journal of Chemistry2020,38,8:2

12Split liver transplantation:What's unique?显示文摘The intraoperative management of split liver transplantation(SLT) has some unique features as compared to routine whole liver transplantations. Only the liver has this special ability to regenerate that confers benefits in survival and quality of life for two instead of one by splitting livers. Primary graft dysfunction may result from small for size syndrome. Graft weight to recipient body weight ratio is significant for both trisegmental and hemiliver grafts. Intraoperative surgical techniques aim to reduce portal hyperperfusion and decrease venous portal pressure. Ischemic preconditioning can be instituted to protect against ischemic reperfusion injury which impacts graft regeneration. Advancement of the technique of SLT is essential as use of split cadaveric grafts expands the donor pool and potentially has an excellent future.Aparna R Dalal 2015World Journal of Transplantation2015,5,3:2

14Green synthesis of bentonite-supported iron nanoparticles as a heterogeneous Fenton-like catalyst:Kinetics of decolorization of reactive blue 238 dye显示文摘This study aimed to synthesize green tea nano zero-valent iron(GT-NZVI)and bentonite-supported green tea nano zero-valent iron(BGT-NZVI)nanoparticles using green tea extracts in an environmentally sustainable way.Bentonite was used as a support material because it disperses and stabilizes GT-NZVI,and it helps to reduce the cost,increase the adsorption capacity of GT-NZVI,and decrease the optimum amount of GT-NZVI used in Fenton-like oxidation.A scanning electron microscope,an atomic force microscope,and a Fourier transform infrared spectroscope were used to characterize GT-NZVI and B-GT-NZVI,while the zeta potential was measured to evaluate the stability of iron nanoparticles.The decolorization kinetics of reactive blue 238(RB 238)dye in the aqueous phase in the Fenton-like oxidation process were investigated as well.The effects of various experimental conditions such as reaction time,dosages of catalysts,concentration of H2O2,temperature,addition of inorganic salts,and other parameters were investigated.The results show that the oxidative degradation efficiencies of RB 238 dye catalyzed by GT-NZVI and B-GT-NZVI were 93.5%and 96.2%,respectively,at the optimum reaction conditions as follows:c(H2O2)¼5 mmol/L,r(GT-NZVI)¼0.5 g/L or r(B-GT-NZVI)¼0.5 g/L,c(RB 238 dye)¼0.05 mmol/L,and pH¼2.5 at 180 min.The best catalytic performance was exhibited when B-GT-NZVI was used.Three kinetic models were employed,and the second-order model was found to be the best model representing the experimental kinetic data of RB 238 dye.The value of activation energy decreased from 38.22 kJ/mol for GT-NZVI to 14.13 kJ/mol for B-GT-NZVI.This indicates that the effect of B-GT-NZVI in decreasing the energy barrier is more pronounced than that of the GT-NZVI catalyst,leading to improved Fenton-like oxidation processes.©2020 Hohai University.Production and hosting by Elsevier B.V.This is an open access article under the CC BY-NC-ND license(http://gffzzeb6f7f563f66445dhb5v9wbopvup569u5.ffgz.tsg.suse.edu.cn/licenses/by-nc-nd/4.0/).Ahmed Khudhair Hassan Ghayda Yaseen Al-Kindi Dalal Ghanim 2020Water Science and Engineering2020,13,4:2

16电源电子技术在降低能耗中的角色显示文摘全世界对能源消耗的关注日渐增加。作为减少能源消耗的两种方式,能源节省需要个人的自觉性加社会决策,而能效提升就纯粹是一个技术问题。美国使用的电能中的3%在电子电源转换过程中耗散为热量。因此电源电子产业,包括半导体公司、电源公司和终端产品制造商正在努力使这些损耗减少一半。他们所采用的方式就是提升大批量消费电子产品中的电源转换效率并降低待机能耗。Chuck Mullett Dhaval Dalal 2008今日电子2008,,4:2
