Journal of Bionic Engineering 2006年第2期3卷 63-71页

A number of investigations into application of polymers for macro-morphological modification of tool surface have been carried out. These researches, with extensive stress on convex or domed protuberations as one of the widely used construction units, have tried to harness benefits from using polymers in agriculture. Ultra high molecular weight polyethylene （UHMW-pE） has proved an emerging polymer in its application to reduce soil adhesion. This research was conducted to study the effect of shape （flat, semi-spherical, semi-oblate, semi short-prolate and semi long-prolate） and dimensions （base diameter and dome height） on sliding resistance and normal adhesion of biomimetic plates. To incorporate both shape and size, a dimensionless ratio of height to diameter （HDR） was introduced to characterize the effect of construction unit＇s physique. Experiments were conducted in Bangkok clay soil with dry （ 19.8% d.b.）, sticky （36.9% d.b.） and flooded （60.1% d.b.） soil conditions respectively. Soil at sticky limit exhibited the highest sliding resistance （77.8 N） and normal adhesion （3 kpa to 7 kpa）, whereas these values were 61.7 N and 〈0.2 kpa in dry, and 53.7 N and 0.5 kpa to 1.5 kpa in flooded soil conditions. protuberances with HDR ≤ 0.5 lowered sliding resistance by 10% - 30% and the same reduced normal adhesion by 10% - 60%. The amount of reduction in both sliding resistance and normal adhesion was higher in flooded soil. Lighter normal loads obviously produced lesser resistance and adhesion.

本文研究了不同浓度的工业蒸馏废液对热带和亚热带常见的三种多用途树种:儿茶(Acacia catechu)、印度黄檀(Dalbergia sissoo)和桑树(Morus alba)种子发芽的影响。影响效果是通过工业蒸馏废液的浓度和种子的不同活力指标来进行研究的,如发芽率,发芽值(germination value)和与对照相比发芽的减少数量等指标。这种工业蒸馏废液的特性是强酸性、高BOD(生物耗氧量)、COD(化学需氧量)、TS(全干物),而DO(溶解氧)极低。较低的废液浓度(10%)促进所有三种树种的种子发芽。然而,高浓度(>10%)则抑制发芽,种子发芽率的高低与废液浓度的递增顺序的关系是>0%>10%<20%<40%<60%<80%。浓度为100%时无发芽的种子。试验结果表明,儿茶种子的抗性和活力比印度黄檀、桑树种子更强,与一般的灌溉用水相比浓度为10%的废液更适合种子发芽。

promising light converting BaMoO_4:Er^(3+)-Tm^(3+)-Yb^(3+) phosphors for display and optical temperature sensing

引用

Journal of Rare Earths 2018年第12期36卷 1256-1263页

作者： Abhishek Kumar soni Vineet Kumar Rai Chemistry Division Bhabha Atomic Research Centre Laser and Spectroscopy Laboratory Department of Applied Physics Indian Institute of Technology (Indian School of Mines)

Er-Tm3+-Ybtri-doped BaMoOphosphors were synthesized by co-precipitation technique and characterized by X-ray diffraction analysis, absorption study and field emission scanning electron microscopy analysis. Upconversion as well as downconversion luminescence studies were performed by using near infrared(980 nm) and ultraviolet(380 nm) excitations. Energy level diagram, pump power dependence and colour coordinate study were utilized to describe the multicolor upconversion emission properties. Under single 980 nm diode laser excitation the dual mode sensing behaviour is realized via Stark sublevels and thermally coupled energy levels of the Tm3+ and Erions in the prepared tri-doped phosphors. A comparative fluorescence intensity ratio analysis for integrated emission intensities arising from the Stark sublevels {~1 G4(a)) and ~1 G4(b))} and thermally coupled energy levels {~2 Hand 4 S3/2} of the Tm3+ and Er3+ ions, respectively was carried out in the prepared tri-doped BaMoOphosphors. The maximum sensitivity for thermally coupled energy levels of the Er3+ and Stark sublevels of the Tm3+ ion was reported. The developed phosphors could be useful in the display devices and optical thermo metric applications.

Xanthomonas axonopodis pv. punicae uses XopL effector to suppress pomegranate immunity

引用

Journal of Integrative plant Biology 2018年第4期60卷 341-357页

作者： Madhvi soni Kalyan K.Mondal Division of plant pathology ICAR-Indian Agricultural Research Institute

Xanthomonas axonopodis pv. punicae （Xap） causing bacterial blight is an important pathogen that incurs significant losses to the exportability of pomegranate. Xap uses the Xop TTSS-effector, via the type three secretion system, to suppress pomegranate immunity. Here, we investigate the role of XopL during blight pathogenesis. We observed that XopL is essential for its in planta growth and full virulence. Leaves inoculated with Xap AxopL produced restricted water-soaked lesions compared to those inoculated with wild-type Xap. XopL supports Xap for its sustained multiplication in pomegranate by suppress- ing the plant cell death （pCD） event. We further demon- strated that XopL suppresses immune responses, such as callose deposition and production of reactive oxygen species （ROS）. RT-qpCR analysis revealed that immune responsive genes were upregulated when challenged with Xap AxopL, whereas upregulation of such genes was compromised in the complemented strain containing the xopL gene. The transiently expressed XopL：：EYFp fusion protein was local- ized to the plasma membrane, indicating the possible site of its action. Altogether, this study highlights that XopL is an important TTSS-effector of Xap that suppresses plant immune responses, including pCD, presumably to support the multiplication of Xap for a sufficient time-period during blight disease development.

Vehicular emissions are considered one of the major anthropogenic sources of greenhouse gases and poor air quality in metropolitan *** study aims to see the correlation of CO_(2),CH_(4),and CO through monitoring over a period from December 2020 to October 2021 covering three seasons’winter,summer,and monsoon at two different traffic locations of Delhi having different traffic volumes,road patterns,and traffic *** annual average morning concentration of CO_(2),CH_(4)and CO was found(533±105),(7.3±3.1),(10.7±3.0)ppm at Najafgarh and(480±70),(5.2±1.8),(7.8±2.8)ppm at Rajendra place,respectively.A relationship between concentration of all three gases and meteorological parameters such as temperature,humidity,wind speed and wind direction has also been investigated using pearson correlation coefficient and pollution rose diagram.A comparable pattern in concentration was observed for all three gases in spatial(location)and temporal(diurnal)*** concentration trend of CO_(2)in different seasons is winter>summer>monsoon,while in the case of CH_(4)winter=summer>monsoon but not any seasonal trend was noted in CO *** is observed that CO_(2)has a good relation with CO(a tracer for vehicular emission)in terms of diurnal variation,whereas,CH_(4)does not represent a relation with CO and CO_(2)diurnally,suggesting that vehicles are the source of CO_(2)but not much contributing to other greenhouse gases like CH_(4).

Combined tests of prostate specific antigen and testosterone will improve diagnosis and monitoring the progression of prostate cancer

引用

Asian Journal of Andrology 2015年第5期17卷 807-810,I0009页

作者： Weitao Song Vikram soni Mohit Khera Scott Department of Urology Baylor College of Medicine Houston Texas 77030 USA

prostate-specific antigen （pSA） testing has been widely used to screen men for prostate cancer （pCa） and to monitor pCa progression. However, more studies have shown that around 15% of men with low or normal pSA levels have pCa. In this study, we aimed to investigate the relationship of androgen and pSA levels and to better understand the reason that some pCa patients have low serum pSA values. The in vitro data demonstrated that cultured LNCap cells ceased to produce pSA after androgen withdrawal and resumed pSA production after androgen was re-added. The in vivo experiment results showed that 48% of pCa xenografts carrying mice have serum pSA level lower than 4 ng ml^-1. The serum pSA levels increased significantly with rises in testosterone （T） levels 1 week after T pellet implantation. These data indicated that the androgen is a key factor controlling the production of pSA. Low serum pSA levels in mice with pCa xenografts are associated with low serum T levels. Raising serum T levels in tumor caring mice will also significantly increase serum pSA level. This may have clinical implications when screening pSA in men, who have occult pCa.
