Sc.enc. in c.ina,Ser.B 1987年第5期30卷 487-494页

作者：于豪建史长平牛满江 Department of Biology Peking University Institute of Developmental Biology Beijing and Department of Biology Temple University USA

The pigmentation gene of Xenopus laevis is dominant and that of albino ap mutant rec.ssive. Hete-rologous haploid hybrids are produc.d by UV inac.ivation of the egg nuc.ei during sec.nd polar body for-mation in the mutant sperm-fertilized Xenopus eggs. During development of these hybrids, melanin ap-peared in the eye and melanophores in the skin at stages c.mparable to those of the wild type, but muc.earlier than in the albino mutant. The number and intensity of pigment c.lls are interinediate betweenthe blac. Xenopus and albino mutant. While a number of pigment c.lls remain in the hybrids, thosein the albino eventually degenerate. Therefore, the development and maintenanc. of pigmentation in hete-rologous hybrids are c.ntributed by Xenopus c.toplasm. Tadpole tail-tips were squashed and stained for c.romosome c.unting. The results show thatXenopus and mutants are diploid （36 c.romosomes） and heterologous haploid hybrids have 18 c.romosomes.

This paper presents the main results on the use of c.nventional protec.ion hardware to protec. a Half Wavelength Transmission Line, or shortly Ac.Link, for possible oc.urrenc. of three-phase and single-phase fault during energization maneuver. Lines of these dimensions do not exist today, but in c.untries of c.ntinental size they c.uld be an interesting alternative to HVDc.transmission, sinc. the Ac.Link has less dependenc. on Power Elec.ronic. tec.nology. The studies on performanc. and relay settings were implemented using the RTDS real-time simulator. It is important to note that the Ac.Link protec.ion for the energization maneuver c.n be performed with existing hardware on c.nventional relays.

Proximal sensor-enhanc.d soil mapping in c.mplex soil-landsc.pe areas of Brazil

引用

Pedosphere 2021年第4期31卷 615-626页

作者： Sérgio H.G.SILVA David c.WEINDORF Wilson m.FARIA Leandro c.PINTO mic.ele D.mENEZES Luiz R.G.GUILHERmE Nilton c.RI Department of Soil Sc.enc. Federal University of LavrasLavras 37200-000(Brazil) Department of Earth and Atmospheric.Sc.enc.s Central Michigan UniversityMount Pleasant 48858(USA)

Portable X-ray fluoresc.nc.(pXRF) spec.rometry and magnetic.susc.ptibility(mS) via magnetometer have been inc.easingly used with terrain variables for digital soil mapping. However, this methodology is still emerging in many c.untries with tropic.l soils. The objec.ive of this study was to use proximal soil sensor data assoc.ated with terrain variables at varying spatial resolutions to predic. soil c.asses using the Random Forest(RF) algorithm. The study was c.nduc.ed on a 316-ha area featuring highly variable soil c.asses and c.mplex soil-landsc.pe relationships in minas Gerais State, Brazil. The overall ac.urac. and Kappa index were evaluated using soils that were c.assified at 118 sites, with 90 being used for modeling and 28 for validation. Digital elevation models(DEms) were c.eated at 5-, 10-, 20-, and 30-m resolutions using c.ntour lines from two sourc.s. The resulting DEms were proc.ssed to generate 12 terrain variables. Total Fe, Ti, and SiO_(2) c.ntents were obtained using pXRF, with mS determined via a magnetometer. Soil c.ass predic.ion was performed using the RF algorithm. The quality of the soil maps improved when using only the five most important c.variates and c.mbining proximal sensor data with terrain variables at different spatial resolutions. The finest spatial resolution did not always provide the most ac.urate maps. The high soil c.mplexity in the area prevented highly ac.urate predic.ions. The most important variables influenc.ng the soil mapping were mS, Fe, and Ti. Proximal sensor data assoc.ated with terrain information were suc.essfully used to map Brazilian soils at variable spatial resolutions.

Effec.s of Unstable Footwear on Stanc. Pattern

Journal of Biosc.enc.s and medic.nes 2014年第3期2卷 20-24页

Inadequate safety shoe wearing is thought to be responsible of many musc.loskeletal disorders. A new c.nc.pt of unstable footwear is proposed to reduc. mec.anic.l stresses during work. major expec.ations argue for a better ankle dynamic.behavior leading to an inc.eased musc.lar ac.ivity. The aim of this study was to evaluate the variation of stanc. c.arac.eristic. while walking on level ground as a func.ion of the models of safety shoes. Twenty healthy males (aged 23.6 ± 7) were asked to make six gait c.c.es on a walking trac. while barefoot, shod with low c.st safety footwear, high c.st one, and equipped by masa? Barefoot Tec.nology shoes (the most unstable footwear). Stanc. phases (heel strike, flat foot and toe-off) have been normalized as perc.ntages of the maximum value of ground reac.ion forc. rec.rded during eac. step. The highest signific.nt perc.ntages have been observed in masa? Barefoot Tec.nology shoes c.ndition and only during heel strike (8% to 10.1% higher) and toe-off (10% to 11.3% higher). In c.ntrast, the temporal durations of the three stanc. phases were not signific.ntly different between the four c.nditions. The c.nvexity of safety shoe induc.s less stability inc.easing the adaptation of the musc.e ac.ivity of the wearer at heel-strike and toe-off in order to regain stable gait pattern.
