3The magnetic properties of Serbian loess and its environmental significance显示文摘This paper reports a loess-paleosol sequence located in the Danube River basin,Serbia,which formed at least since the latest part of the early Pleistocene,and before the paleomagnetic B/M boundary.Various magnetic parameters of the Serbian V-L1-V-S4 loess-paleosol sequence have been measured and analyzed in the Titel Loess Plateau.These parameters show a very similar magnetic behavior compared with that of the Chinese loess.There is a general positive relationship between magnetic susceptibility() and pedogenesis.The main contributors to are the magnetic grains of SP(superparamagnetic) and SD(single domain) magnetic domains,while MD(multi domain) contributes only a small percentage.The difference in between loess and paleosol mainly is caused by pedogenesis.The very fine magnetic minerals increase gradually with increasing soil development(from loess to soil),and they lead to higher.The thermomagnetic curves show thatmagnetic minerals in the loess layers are magnetite and maghemite,both providing a major contribution to.In contrast the paleosol layers mainly are composed of magnetite,with almost no or a very small amount of maghemite,as implied by a reversible thermomagnetic behavior.This indicates that pedogenic conditions during V-S3 and V-S4 strong soil development have resulted in maghemite that is no longer stable,and has been resolved or converted to other stable phase minerals.This likely indicates that soil moisture during V-S3 and V-S4 development exceeded a critical condition of maghemite stability.LIU XiuMing LIU Zhi Lü Bin MARKOVI S B CHEN JiaSheng GUO Hui MA MingMing ZHAO GuoYong FENG Hua 2013Chinese Science Bulletin2013,58,3:7

8Common non-synonymous polymorphisms in the BRCA1 Associated RING Domain (BARD1) gene are associated with breast cancer susceptibility:a case-control analysis显示文摘The BRCA1 Associated RING Domain(BARD1) gene has been identified as a high penetrance gene for breast cancer, whose germline and somatic mutations were reported in both non-BRCA1/2 hereditary site-specific and sporadic breast cancer cases. BARD1 plays a crucial role in tumor repression, along with its heterodimeric partner BRCA1. In the current study, we tested the hypothesis that common non-synonymous polymorphisms in BARD1 are associated with breast cancer susceptibility in a case-control study of 507 patients with incident breast cancer and 539 frequency-matched cancer-free controls in Chinese women. We genotyped all three common(minor allele frequency (MAF) > 0.10) non-synonymous polymorphisms(Pro24Ser, Arg378Ser, and Val507Met) in BARD1. We found that the BARD1 Pro24Ser variant genotypes(24Pro/Ser and 24Ser/Ser) and Arg378Ser variant homozygote 378Ser/Ser were associated with a significantly decreased breast cancer risk, compared with their wild-type homozygotes, respectively. Furthermore, a significant locus-locus interaction was evident between Pro24Ser and Arg378Ser (P-int = 0.032). Among the 378Ser variant allele carriers, the 24Pro/Pro wild-type homozygote was associated with a significantly increased breast cancer risk (adjusted OR = 1.81, 95% CI = 1.11-2.95), but the subjects having 24Pro/Ser or Ser/Ser variant genotypes had a significantly decreased risk(adjusted OR = 0.74, 95% CI = 0.56-0.99). In stratified analysis, this locus-locus interaction was more evident among subjects without family cancer history, those with positive estrogen receptor (ER) and individuals with negative progesterone receptor(PR). These findings indicate that the potentially functional polymorphisms Pro24Ser and Arg378Ser in BARD1 may jointly contribute to the susceptibility of breast cancer.Huo, X Hu, Z. B Zhai, X.

9全颗粒饲料对奶牛生产性能的影响显示文摘饲料中的中性洗涤纤维(NDF)含量和饲料颗粒直径是影响瘤胃功能的重要因素。试验评估了以颗粒饲料为主的奶牛瘤胃健康情况、NDF消化率和生产性能。选取8头荷斯坦母牛(336±30 d,体重346±35 kg),随机分配到交叉重复试验组中,奶牛安置于牛栏,自由采食。试验期为3周,前两周是适应期,最后一周为数据收集期。各组饲粮原料相同,但物理形式不同,分为全混合日粮(TMR)和颗粒料(直径=8 mm)。两组间物理有效NDF(pe NDF)不同,TMR组为39.8%,颗粒料组为11.8%。在试验过程中,干物质采食量(DMI)、饮水量、瘤胃反刍时间、瘤胃温度和pH情况均记录。3周后收集粪样,确定潜在的可消化NDF总消化率(pdNDF)。每阶段结束后计算平均日增重和饲料转化率。颗粒料组的DMI、DMI/体重和饮水量更高。而两组间平均日增重和饲料转化率无显著差异。颗粒料组的瘤胃反刍时间为241 min·d-1低于TMR组的507 min·d-1。饲料的不同物理外形对瘤胃温度、瘤胃pH无显著影响。TMR组的pdNDF总消化率为90.25%高于颗粒料组的86.82%。试验结果表明,动物易接受完整的颗粒饲料,DMI较高,且反刍时间减少,但瘤胃pH无显著变化。TMR组的pdNDF消化率显著增加。尽管两组奶牛在DMI和纤维消化方面表现不同,但总体表现相似,两组饲料的保存时间与其物理形式有关。在短期内,提供能满足NDF需求的完全颗粒饲料可改善瘤胃健康状况和动物生产性能,而较长时间的数据则需要进一步试验。Wang J Yang M Cao M Lin Y Che L Q Duraipandiyan V Al-Dhabi N A Fang Z F Xu S Y Feng B Liu G Wu D Bonfante E Palmonari A Mammi L Canestrari G Fustini M Formigoni A 2016饲料博览2016,0,12:2

13Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2.Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q 2006Journal of Semiconductors2006,27,4:2
