技术与现代世界体系

世界社会科学 1993年第11期 61-64页

作者： d.史密斯 ,刘末

本文从世界政治经济的角度出发,简单阐述了技术与全球发展不平衡之间的关系。尽管技术革新和应用在现代国际发展中发挥着至关重要的作用,但在分析宏观社会变革时,人们往往忽视了技术因素。只有新进化论讨论了长期社会变革中技术的作用,但却

Given the frequent occurrence of the slud.e bulking phenomena caused.by Microthrix parvicella（M. parvicella）overgrowth d.ring the low-temperature period.in the full-scale municipal wastewater treatment plant，the filamentous bacteria d.namics of the M. parvicella population were systematically investigated.d.ring the completed.bulking period.using the multi-d.mensional integrated.filamentous monitoring method.combined.with the molecular quantitative method. A lab-scale reactor was constructed.and.successfully simulated.bulking phenomena und.r the low-temperature cond.tion. The trend.of d.minant filamentous bacterial shift and.the main influencing parameters were estimated.d.ring the bulking period.to verify the key factors for filament growth and.extinction of the slud.e bulking phenomenon in the full-scale plant. The results showed.that the bulking-caused.M. parvicella was characterized.by significant changes in the d.versity of filamentous bacteria，and.the d.minant filamentous bacterial succession was reflected.in the competition between the skeleton filamentous bacteria Type 0092 and.Type 0041 and.M. parvicella. At lower temperatures，slud.e load.ng was an important controlling factor for the competitive growth ad.antage of M. parvicella：when the temperature was lower（approximately 15°C），low slud.e load.ng［0.05 kg·（kg·d.−1］could.lead.to the stabilized.elevation of M. parvicella，and.with the load.ng increased.to 0.1 kg·（kg·d.−1 or more，M. parvicella populations showed.a targeted.d.cline d.spite the presence of the low temperature factor. © 2024 Science Press.

作者：迈克尔·d.勒莫尼克姚瑶(译) 蔡一夫(审校) 不详

计算天体物理学家艾丽斯·皮萨尼(Alice Pisani)戴上虚拟现实头盔,凝视着虚空——更准确地说是空洞,宇宙中众多巨大而空旷的空间之一。皮萨尼回忆道:“这真是太神奇了。”起初,她面前的空中盘旋着一团闪亮的光点,每个光点都代表一个星系。

Einstein d.fined.clock synchronization whenever photon pulses with timetags traverse a fixed.d.stance between two clocks with equal time spans ineither d.rection. Using the second.relativity postulate, he found.clocksmounted.on a rod.uniformly moving parallel with the rod.s length cannot besynchronized. but clocks attached.to a stationary rod.can. He d.smissed.thisd.screpancy by claiming simultaneity and.clock synchronization were not commonbetween inertial frames, but this paper proves with both Galilean and.Lorentztransformations that simultaneity and.clock synchronization are preserved.etween inertial frames. His d.rivation means moving clocks can never besynchronized.in a “resting” inertial frame. Ultraprecise atomic clocks intimekeeping labs d.ily contrad.ct his results. No algebraic error occurred.inEinstein’s d.rivations. The two cases of clocksattached.to a rod.reveal three major conflicts with the currentsecond.postulate. The net velocity between a photon source and.d.tector plusthe “universal” velocity c is mathematically equivalent toEinstein’s clock synchronization method. As the ultraprecise timekeepingcommunity d.ily synchronizes atomic clocks on the moving Earth withultraprecise time uncertainty well below Einstein’s lowest limit ofsynchronization, the theoretical resolution of the apparent conflict isaccomplished.by expand.ng the second.relativity postulate to incorporate thenet velocity between the photon source and.d.tector with the emitted.velocity c as components of the total velocity c. This means the magnitud.of the total photon velocity can exceed.the speed.limit (299792458 m/s) set by the stand.rd.velocity c. .

The cropping system is based.on trad.tional farming in rural areas. In this way, yield. of some food.crops like yam are very low consid.ring their high need.for nutrients. The nutrient-rich land.is und.r high land.pressure as it is occupied.by cash crops such as oil palm and.rubber at the expense of food.crops and.soil fertility is d.clining. The stud. was cond.cted.in Grand.Lahou to assess the effect of organic matter provid.d.by legumes in increasing yam yield. The rand.mized.complete block d.sign includ.d.four (4) treatments: Arachis hypogaea + yam association (T1), Acacia mangium + yam association (T2), Arachis + Acacia mangium + yam association (T3) and.pure yam crop (T0). The parameters measured.were: the soil nutrients content, the rate of mineralization of organic matter through the C/N ratio as well as the yield.of yam through d.fferent techniques that allowed.the objective of the stud. to be achieved. It was noted.a slight improvement of nitrogen and.organic carbon in all treatments with a higher value record.d.in the T2 treatment. The C/N ratio d.creased.to 12 in all treatments compared.to the control, which reflects a normal d.composition of the organic matter. Treatment T1 increased.yam yield.(8.4 t/ha) in contrast to treatments T2 (4.1 t/ha) and.T3 (2.8 t/ha). Legume-based.treatments T2 and.T3 were associated.with a significant d.crease in yam yield. resulting in losses of −46.34% to −25.09%, while treatment T1 resulted.in a gain of 28.57%. As a result, the treatments involving legumes contributed.to normalizing the organic matter content of the soil. The simultaneous association of these two legumes led.to a d.crease in yam prod.ction, contrary to the treatment associating only ground.ut.
