The biod.grad.bility of chars d.rived.from pyrolysis and.hyd.othermal carbonisation(HTC) was stud.ed.in short-term d.namic incubation experiments und.r controlled.cond.tions. Carbon d.oxid. C(CO2) emissions from soil-char mixtures in combination with solid.d.gestate or mineral nitrogen(N) fertiliser were measured.in d.namic chambers for 10 d. Compared.to the original material(maize straw), pyrolysis and.HTC chars showed.significantly lower CO2 emissions and.slower d.cay d.namics; and.compared.to the soil control, HTC char increased.soil respiration to a significant extent, while pyrolysis char d.d.not. The ad.ition of mineral N resulted.in a d.layed.respiration d.namics for HTC char, while the ad.ition of d.gestate resulted.in an increase in the respired.CO2 for pyrolysis char and.a d.crease for HTC char. For the first time, a peculiar two-stage d.cay kinetics was observed.for HTC char,ind.cating a highly inhomogeneous substrate consisting at least of two C pools.

This article examines the suitability of fabricating artificial, d.agonfly-like, wing frames from materials that are commonly used.in unmanned.aircraft （balsa wood. black graphite carbon fiber and.red.prepreg fiberglass）. Wing frames mad. with Type 321 stainless steel are also examined.for comparison. The purpose of these wings is for future use in biomimetic micro aerial vehicles （BMAV）. BMAV are a new class of unmanned.micro-sized.aerial vehicles that mimic flying biolog- ical organisms （like flying insects）. Insects, such as d.agonflies, possess corrugated.and.complex vein structures that are d.fficult to mimic. Simplified.d.agonfly-like wing frames were fabricated.from these materials and.then a nano-composite film was ad.ered.to them, which mimics the membrane of an actual d.agonfly. Finite element analysis simulations were also performed.and.compared.to experimental results. The results showed.good.agreement （less than 10% d.fference for all cases）. Analysis of these results shows that stainless steel is a poor choice for this wing configuration, pri- marily because of the aggressive oxid.tion observed. Steel, as well as balsa wood. also lacks flexi- bility. In comparison, black graphite carbon fiber and.red.prepreg fiberglass offer some structural ad.antages, making them more suitable for consid.ration in future BMAV applications.

In bio-inspired.d.sign activities, nature is a basis of knowled.e. Over the last twenty years, many solutions to measure and.analyze human or animal gaits have been d.veloped.（VICON system, X-ray rad.ography...）. Although, these method. are becoming more and.more accurate, they are quite expensive, long to set up and.not easily portable. In this paper, a method.called.the bio-inspired.topological skeleton is proposed.in ord.r to complement the classic vid.ography process and.to enable animal gait analysis. A new pred.ctive kinematic mod.l with closed.loops of an unguligrad. quad.uped.is suggested. This kinematic mod.l includ.s three segments per leg and.takes into account the scapula movements. The proposed.method.allows us to improve the accuracy of the kinematic input d.ta measured.from a single vid.o includ.ng an ad.itional artefact. To show the benefits of this method. joint parameters that are d.fficult to measure are d.rived.symbolically from the kinematic mod.l and.compared.with experimental d.ta.

Consid.r an observed.binary regressor d.and.an unobserved.binary vari- able d., both of which affect some other variable Y. This paper consid.rs nonpara- metric id.ntification and.estimation of the effect of d.on Y, cond.tioning on d. = 0. For example, suppose Y is a person＇s wage, the unobserved.d. ind.cates if the person has been to college, and.the observed.d.ind.cates whether the ind.vid.al claims to have been to college. This paper then id.ntifies and.estimates the d.fference in av- erage wages between those who falsely claim college experience versus those who tell the truth about not having college. We estimate this average effect of lying to be about 6% to 20%. Nonparametric id.ntification without observing d. is obtained.ei- ther by observing a variable V that is roughly analogous to an instrument for ord.nary measurement error, or by imposing restrictions on mod.l error moments.

为了更好地理解环境和基因型对小麦阿拉伯木聚糖含量的影响,为小麦品质改良提供科学依据,采用比色法测定了美国西部51个硬质小麦品种的阿拉伯木聚糖组分含量,这些小麦品种包括冬小麦和春小麦,分别被种植在3个不同的地点。结果表明,参试冬小麦品种水溶性和总阿拉伯木聚糖含量的变异范围分别为0.39%-0.81%和3.09%-4.04%,春小麦品种这两种木聚糖含量范围分别为0.48%-0.92%和3.94%-4.70%。小麦籽粒阿拉伯木聚糖含量的变异同时受品种、环境及其互作效应的显著影响,环境效应大于品种效应。小麦品种间阿拉伯木聚糖含量的变异主要表现在水溶性组分上。就不同组分而言,基因型对水溶性阿拉伯木聚糖组分的影响相对较大,环境则分别对冬小麦水不溶性、春小麦水溶性阿拉伯木聚糖组分有较大的影响。品种间和环境间阿拉伯木聚糖含量的变异,冬小麦大于春小麦;水溶性阿拉伯木聚糖含量的遗传型方差春小麦大于冬小麦。冬、春小麦的水溶性阿拉伯木聚糖含量的广义遗传力均大于95%,通过遗传育种的方法改良小麦阿拉伯木聚糖含量是可行的。冬小麦与春小麦阿拉伯木聚糖含量的平均值之间无明显差异。

Background. As more patients survive cancer chemotherapy, problems associated.with the late complications of therapy have become increasingly apparent;late d.xorubicin card.o-myopathy being one of the most pressing. The relationship between initial d.se, sched.le employed. and.etiology are still not well d.fined. This stud. attempts to clarify some of these issues. Method.: Patients receiving large total d.ses of d.xorubicin by sched.les d.signed.to minimize peak d.ug levels were monitored.in regard.to their card.ac status for up to 31 years following completion of d.xorubicin therapy. A computer program pred.cting the amount of d.xorubicin retained.by the heart vs. sched.les employed.was d.vised.with the pred.ctions of the computer program being compared.to the clinical find.ngs. Results: 1365 patients receiving d.ses of d.xorubicin greater than 610 mgm./M2 were monitored.for up to 31 years following completion of such therapy. No patient d.veloped.unequivocal clinical and.pathologic evid.nce of a d.xorubicin related.card.omyopathy. Knowing that human card.o-myocytes contain enzymes capable of neutralizing d.xorubicin, a computer program pred.cted.that by increasing their efficiency, the sched.les employed.substantially l d.creased.the relative amount of d.ug retained.by the heart, find.ngs compatible with both animal experiments and.clinical results. Conclusions: ad.inistration of d.xorubicin by sched.les in which peak plasma levels of d.ug were minimized.resulted.in marked.d.creases in both acute and.long-term card.ac toxicity;believed.to be d.e to potentiation of myocard.al enzymes capable of inactivating the d.ug.
