最近,大量的合成纳米材料被广泛用于制药,电子,化妆品,诊断成像,光热疗法,核酸传递,催化和材料科学,环境修复以及清洁能源生产医疗设备,纺织等行业中。大量的合成纳米材料释放到市政污水处理厂中造成了污染。广泛用于市政废水处理的序批式反应器(SBR)传统上并不是以去除纳米颗粒而设计的。目前,ZrO-NPs对SBR系统性能的影响仍然未知。在这项研究中,使用实验室规模的SBR系统研究ZrO-NPs在不同粒径条件下(例如:200nm,100nm,50nm和15nm)对活性污泥性能及其特性和细菌群落动态的影响。实验室规模的浸没式SBR系统连续在纳米材料的胁迫下连续运行72天。在运行72天后发现,浓度为0.1g/L的ZrO-NP(200nm,100nm,50nm和15nm)会对氮,磷和COD(化学需氧量)的去除产生不利影响。SBR-C对照组实验表示不添加NP的反应器中NH-N为(88.9±1.7%),但SBR-T中,NH-N的去除率显着降低(p0.05),但SBR-T的去除效率分别为(59.8±4.6%,57.3±5.1%和54.8±5.7)%)和COD(88.4±2.8%,86.3±4.1%,81.9±4.3%),粒径对应于100,50,15nm。200 nm的ZrO-NP不会抑制NH-N,PO-和COD的去除。根据硝化抑制试验,15 nm NPs诱导更高的抑制33.61±2.13%。暴露于50和15nm时,需氧增加的松散结合多糖(LB-PS)为55.82 mg/g VSS(5.6%)和紧密结合(TB-PS)为72.8mg/g VSS(27.5%),两者结合成一个整体EPS(细胞外物质)。持续暴露于ZrO-NPs下也改变了活性污泥的表面形态,导致污泥脱颗粒。通过SEM(扫描电子显微镜)证实,15 nm ZrO-NPs导致最大污泥表面变质。能量色散X射线(EDX)显示,平均无机元素重量分布增加,其中Na(2.75%),Cu(1.23%),P(12.64%),Mg(9.41%),K(2.79%),Ca12.34%),Fe(15.66%)和Pt(11.8%),但Cl降至(0.36%)。通过变性梯度凝胶电泳(DGGE)进行的分析表明,较小的NP(50和15 nm)会显着抑制典型的氨氧化细菌(Nitrosococcus sp,Shewanella denitrificans)的生长,该细菌主要是将氨氧化为硝酸盐。结果表明,活性污泥细菌群落的异质性和分布在NPs大小梯度之间显着变化。在200nm,100nm,50nm和15nm的ZrO-NPs上,以A>B>C>D(香农指数:2.99,1.51,1.48,1.18)的顺序观察到更大的群落多样性。变形杆菌(73.46%,60.91%58.48%和90.36%),拟杆菌(19.8%,22.3%,68.16%和5.01%)以及Firmicutess在菌门水平的相对丰度更高。其他门只分别显示变化B>C>D顺序)。然而,荧光原位杂交(FISH)分析显示,在100、50和15nm的TSS ZrO-NPs中,100mg/g的聚磷酸盐积累生物(PAOs)下降了52.6%,47.8%和39.5%。本研究表明,减小纳米尺寸和减少异质性可以增强对活性污泥系统的抗菌作用,并可能在存在ZrO-NP的情况下引发水安全风险。

多（彳圣）效是GNSS恶劣环境下的重要影响因素之一,近年来,GNSS领域研究者在抑制多（彳圣）和提高智能手机导航性能方面进行了广泛研究。但在某些恶劣环境中,由于GNSS信号无法到达,从而导致智能手机无法实现导航。本研究的主要目标是为在多（彳圣）环境下基于智能手机的行人导航提供一种精确的解决方案,在超低成本下实现更高精度的行人定位方案。利用低通滤波器对数据进行预处理,去除其中的高频噪声,使信号平滑。航向和步长估计产生的累积误差分别由平均累积航向误差（MCHE）和累积步长误差（CSLE）表征。最后,采用最优扩展卡尔曼滤波（EKF）算法实现GNSS和PDR数据的融合,并得到最终结果。方案的验证实验是基于智能手机上的微机电系统（MEMS）传感器,而无需额外的硬件,而且采用最新安卓版本的智能手机用于记录GNSS和MEMS传感器的数据文件。实验是在真实场景下进行的,行人步行的路线是具有三个垂直转弯的矩形线路。融合结果表明,本文提出的方法探索了在GNSS或PDR信息不可用时使用智能手机进行导航的多种情形。融合结果也与其他可用的导航解决方案进行了比较。另外通过大量的仿真,证实了本文提出的方法比现有算法更为可靠。

随着能源需求的增加,空气污染正在上升.为了缓解这个问题,冷、热、电(CCHP)系统的联合生产因其最大的燃料利用率和低排放而受到全世界的关注。案例研究建议CCHP系统应在最佳方案下运行。现阶段的研究以采用多种方法对CCHP系统的优化运行,调度和设计等关键问题进行研究。本文重点研究了 CCHP系统的优化模型设计,调度和数值分析,与传统的单独系统(SGS)相比较。除了电等效跟随(EEF)和热等效跟随(TEF)之外,还提出并探索了电热等效跟随(ETEF)运行策略。构建了描述系统成本,可靠性和生态可行性的多目标优化模型。在Matlab中,基于内点法对模型进行求解。内点法具有良好的鲁棒性和较短的收敛时间,易于处理不等式约束和少量迭代到最优潮流困境等优点。确定成本最小化,一次能源节约和碳排放等指标评估CCHP系统性能并与假定的单独网供工业负荷相比较。本文提出了两种不同的模型设计,以确保冬季和夏季冷、热、电负荷供应,通过降低总成本和二氧化碳排放来最大限度地节约能源。在研究日前优化调度之前,首先在Matlab中采用径向基函数进行日前负荷预测,因为它在微电网的运行和控制中起着重要作用。类似地,研究了考虑实时数据和预测误差的实时最优调度。提出了离网控制,直接负荷控制等控制策略以进一步优化系统调度。最后,比较每种控制策略与模型,即夏季和冬季,的结果了以评估所提模型性能。结果表明,与SGS相比,所有控制策略都使CCHP系统的燃料节省,经济和生态性能最大化,但对于假定工业负荷,ETEF模式经济型更好而在节约能源与环境层面EEF模式表现更佳.

目的:慢性心力衰竭（chronic heart failure,CHF）是各种心血管系统疾病发展至后期的共同病理生理表现,是心肌细胞功能严重受损的阶段,也是导致患者死亡的主要原因。目前,CHF是慢性心血管疾病中发病率和住院率都相对较高的疾病,已经成为现阶段危害全球公众生命健康的重要问题。据基础研究和临床资料显示,CHF的主要发病机制涵盖以下四个方面,一是心室重构,二是心肌重构,三是能量重塑,四是心电重塑。在CHF发生发展过程中,多伴有复杂的慢性炎症免疫应答,多种炎症细胞、炎症因子参与其中。目前研究较多的一些炎性因子,如肿瘤坏死因子-α（TNF-α）、高敏c反应蛋白（hs CRP）、核因子-?B（NF-?B）等多种因子并不能全面评估CHF的进展、严重程度及预测心血管事件的发生。人软骨糖蛋白39（YKL-40）是发现不久的一种炎症介质,可参与免疫应答、细胞增殖分化以及细胞外基质重构等多个方面,并且在参与反应过程中发挥重要作用。有关文献指出,YKL-40可以作为LVEF降低心衰预后的独立危险因子,但是现阶段关于此研究还尚少。关于YKL-40在CHF患者血浆中水平的变化、在CHF患者心肌内所发挥的作用以及其表达产生的主要影响因素尚未明确,仍需深入的研究探索。因此我们拟通过对血浆中YKL-40水平与BNP、GDF-15、hsCRP的关系为主要研究方向,以明确CHF患者中对YKL-40产生影响的主要因素,对CHF病人不同心功能分级组间血浆中的YKL-40含量加以测定分析,为YKL-40评估CHF的价值提供更可靠的理论依据,为CHF的诊断和治疗提供新的判定指标,并探究该因子能否作为诊断CHF的独立因素,以及其与当前评估慢性心力衰竭指标之间的关联性。方法:本研究选取2018年01月至2019年12月于济宁医学院附属医院心内科诊断为CHF病人90例,男性病例51例,女性病例39例,年龄在26-88岁范围之间,平均年龄为64岁;从疾病类型来分,其中:缺血性心脏病（IHD）为48例、瓣膜性心脏疾病（VHD）为16例、扩张性心肌病为（DCM）为14例、高血压性心脏病（HHD）为8例、原发性肥厚性心肌病（VHD）为4例,排除由于其他因素引发的心脏性疾病、脑中风、结缔组织病、自身免疫病、甲亢腺功能减退或亢进、先天性心脏病、近期严重感染或重大手术病史等。全部病例符合《2018中国心力衰竭诊断和治疗指南》的诊断标准,参考NYHA心衰标准分级,病人的病程均超过半年,其中NYHA分级为II级的病人有15例,为Ⅲ级的病人有36例,为Ⅳ级的病人有39例;对照组:选择到医院进行健康体检的90例健康人群血浆标本,以及心脏超声,年龄最小为23岁,最大81岁,平均为63岁,男女比例构成分别为男50例和40例;全部进行常规体格检查,并完善辅助检查,排除其他系统疾病病人。CHF组的90例病人和对照组的90例健康者在年龄、性别等方面没有显著差异。采用酶联免疫吸附试验（ELISA）进行检测血浆中的YKL-40、BNP、hsCRP、GDF-15含量;心脏超声测定LVEF（采用改良Simpson法）、心腔大小、室壁厚度等心脏结构功能指标。结果:（1）心衰组与对照组基本信息比较:心衰组和对照组在年龄、体重、TG、HDL-L、LDL-L、AST等方面没有存在明显的差异（p＞0.05）;但是在SBP、DBP、HR、GLU、ALT、BUN、Cr、UA、LDH、HBDH、LVEF、总胆红素等方面具有明显的差异（p＜0.05）。（2）心衰组患者血浆YKL-40水平明显高于对照组[12.665（9.637,19.035）ng/mL vs8.180（5.880,11.420）ng/mL,P＜0.001];CHF组血浆GDF-15亦明显高于对照组[21.860（12.245,38.710）vs6.210（5.740,6.790）（P＜0.001）];CHF组血浆hsCRP高于对照组[2.136（0.589,4.042）vs0.525（0.403,0.800）（P＜0.001）]。（3）心衰分级亚组比较用两独立样本U检验,随着NYHA分级的增高,血浆YKL-40亦呈升高趋势,不同心功能分级之间血浆YKL-40差异具有显著统计意义（P＜0.05）。（4）CHF组病人血浆中GDF-15含量与心功能等级有关,心功能分级越高,GDF-15含量越高,而hs-CRP含量与心功能分级没有明显关联,可能与亚组样本量偏少有关。（5）采用Spearman检验相关性:不同分级CHF组患者血浆YKL-40水平与hsCRP、BNP以及GDF-15呈现正相关性,BNP和GDF-15两者之间也呈良好的正相关,hsCRP和BNP之间没有显著关联。（6）以YKL-40为因变量纳入多元回归,回归方程式YKL40=12.703+0.602×h

Dramatic changes in climatic conditions that supplement the biotic and abiotic stresses pose severe threat to the sustainable rice production and have made it a difficult task for rice molecular breeders to enhance production and productivity under these stress factors. The main focus of rice molecular breeders is to understand the fundamentals of molecular pathways involved in complex agronomic traits to increase the yield. The availability of complete rice genome sequence and recent improvements in rice genomics research has made it possible to detect and map accurately a large number of genes by using linkage to DNA markers. Linkage mapping is an effective approach to identify the genetic markers which are co-segregating with target traits within the family. The ideas of genetic diversity, quantitative trait locus（QTL） mapping, and marker-assisted selection（MAS） are evolving into more efficient concepts of linkage disequilibrium（LD） also called association mapping and genomic selection（GS）, respectively. The use of cost-effective DNA markers derived from the fine mapped position of the genes for important agronomic traits will provide opportunities for breeders to develop high-yielding, stress-resistant, and better quality rice cultivars. Here we focus on the progress of molecular marker technologies, their application in genetic mapping and evolution of association mapping techniques in rice.

Economic Assessment of Sugarcane (Saccharum officinarum L.) through Intercropping

引用

Journal of Agricultural Chemistry and Environment 2014年第3期3卷 24-28页

作者： abdul rehman Rafi Qamar Jamshaid Qamar Agronomy Section Central Cotton Research Institute Sakrand Sindh Pakistan Department of Agronomy University College of Agriculture University of Sargodha Sargodha Pakistan

Sugarcane has pronounced importance to provide sugar for more than half of the global population. World population is enhancing day-by-day and production land is in the worst situation. The cultivated land is diminishing rapidly due to urbanization, road construction, and land deterioration. This crisis demands alternate research to raise crop productivity and maximize the economic returns per unit land for feeding the gigantic population. Sugarcane is a long duration crop and gave late net economic return. Intercropping in sugarcane received much attention and need to properly manage for getting higher net return from same unit area. It is becoming popular among farming community due to resourcefully utilization of land. Intercropping has the potential to inspire the farmers to get maximum economic return per acre per annum. For intercropping, wheat, gram, soybean, and potato were used as an intercrop in September-sown sugarcane. Triple row strip planting geometry of sugarcane with four intercropped (SC + Wheat, SC + Gram, SC + Soybean, and SC + Potato) and check with sole SC was used. Sugarcane was planted during September 2011- 12 and 2012-13 at research area University College of Agriculture, University of Sargodha, Pakistan. Randomized complete block design with three replications were used. Results showed that number of millable cane, cane diameter;unstripped and stripped cane yield and crop growth rate was significantly higher in sole sugarcane when compared with different intercrop in 2011-12 while trend was same in 2012-13. Cane diameter and un-stripped cane yield were statistically at par of intercrops SC + Soybean and SC + Potato while stripped cane yield of Sole SC and SC + Potato was statistically at par in 2012-13. In both the year of study, intercrops gave higher land equivalent ratio and net return over sole sugarcane planted while sole sugarcane gave maximum benefit cost ratio compared with other intercrops.
