Advances in Aging Research 2019年第2期8卷 29-41页

Although congenital sensorineural hearing loss (ShL) in the bilateral cochleae mainly results from genetic abnormalities, chronic ShL progressing in later life is often influenced by systemic immune disturbances, including autoimmunity, chronic inflammation, and immunosenescence. We have investigated the relationship between the inner ear and systemic immunity and reviewed the possibilities to prevent ShL, including autoimmune ShL and age-related ShL. We also demonstrated two lymphocyte populations, interleukin 1 receptor type II (IL-1R2)-positive T cells (T1R2) and naturally occurring regulatory T cells (nTregs) in CD4+ T cells, which increase with aging, suppress host immune function and promote organ degeneration. Alterations in systemic immunity by fewer microbial antigen challenges in the living environment, elimination of immune suppressive lymphocytes, or immune rejuvenation with a reconstituted thymus may contribute not only to renew the cochlear function in ShL, but also to extend the healthy life of functional organs in a vigorous and youthful body, one of humanity’s greatest dreams.

在意大利进行了关于超积累植物布氏香芥(Alyssum bertoloonii)对超镁质土壤中镍的植物潜在采矿作用的实验。在托斯卡钠区穆洛(Murlo)特定的现场实验小区,在两年内以不同的方式施肥。最优化的化肥处理方式(N+K+P)使可再生产的生物量增加了两倍,增至9.0t/ha(吨/公顷),未施肥时的镍含量没有稀释。于物质中0.8%(灰分中11%)的镍含量在不需重播而收获的情况下将会产生72kg/ha的镍含量。植物的年龄和它的镍含量之间没有相关性。土壤长期收获的供养能力用ph值为2,4,6的Kh phthalate溶液的有序浸出来模拟,其显示出768μg/g的极限有效镍含量。于是在根际ph值为6时仅仅七次以上收获才会降低有效Ni场30%。关于植物采矿的一个推荐模式包括12个月后收获这个收成和焚烧这些物质来生产出无硫的生物矿(含大约11%的Ni)。燃烧能量的利用也被讨论。本文认为布氏香芥或香芥属的其它种可用于地中海地区,包括安纳托利亚高原,还有澳大利亚西部和美国西部的植物采矿。植物采矿的经济限度被提出,并且按照现行的国际价格,这项技术在至少有和香芥属相同生物量的植物中仅仅对Ni和Co是可行的。具有较高生物量和类似对Ni吸收潜力的植物能够把界限扩展到其它元素。

4千兆赫无线电设备用的低噪声放大器已设计成功,并投入生产。其噪声系数≤2分贝,典型增益值是10分贝,输入和输出回波损耗≥25分贝。当电源或低噪声晶体管任何一个失效时,其插入损耗通常为5～8分贝。该放大器采用了把一个砷化镓场效应晶体管与一个利用环型器的无源可靠旁路网络相连接的方法。这种方法可以使噪声系数和增益平坦度对每一个放大器都是最佳状态,而无须对输入和输出匹配进行折衷考虑。可以断定,这种单级晶体管放大器的设计与平衡放大器的设计相比,在性能和简单化方面都具有显著的优点。

Journal of Modern Physics 2022年第6期13卷 969-991页

Extending the spacetime manifold of general relativity (GR) to incorporate the hubble expansion of space as a specific curvature, generates a modified solution with three additional non-zero Christoffel symbols and a reformulated Ricci tensor and curvature. The observational consequences of this reformulation are compared with the ΛCDM model for luminosity distance using the extensive type 1a supernovae (SNe 1a) data with redshift corrected to the CMb, and for angular diameter distance using the recent baryonic acoustic oscillation (bAO) data. For the SNe 1a data, the modified GR and ΛCDM models differ by mag. over zb>cmbb> = 0.01 - 1.3, with overall weighted RMS errors of ±0.136μb>bb> mag for modified GR and ±0.151μb>bb> mag for ΛCDM respectively. The bAO measures span a range z = 0.106 - 2.36, with weighted RMS errors of ±0.034 Mpc with hb>0b> = 67.6 ± 0.25 for the modified GR model, and ±0.085 Mpc with hb>0b> = 70.0 ± 0.25 for the ΛCDM model. The derived GR metric for this new solution describes both the SNe 1a and the bAO observations with comparable accuracy to the w’ΛCDM model. by incorporating the hubble expansion of space within general relativity as a specific curvature term, these observations may be described without requiring additional parameters for either dark matter or accelerating dark energy.

Rosmarinus officinalis essential oil obtained by hydrodistillation was tested as corrosion inhibitor of steel in 0.5 M h2SO4 using weight loss measurements, and electrochemical .polarisation methods. Results obtained indicate that the corrosion rate is reduced and R. officinalis oil adsorbs on the metal surface and then inhibits corrosion process. Its inhibition efficiency increases with oil increasing content to reach 61% at 1 g/L. Polarisation curves indicate that RO acts as a cathodic inhibitor. The inhibition efficiency of naturally oil remains slightly constant with the rise of temperature. Chemical analysis of R. officinalis essential oil was carried out using capillary GC and GC/MS. The oil composition was characterized by high amount of oxygenated monoterpene （77%） with 1,8-cineol （52.1%） as main component. Discussion of adsorption was investigated on the the isotherm adsorption of essential oil on basis of essential oil composition. Finally the steel has been also reported.
