In this study, Xenopus laevis were exposed to Aroclor 1254 at doses 0, 400ngL^(-1, 2μgL^(-1), l0μgL^(-1), 20μgL^(-1) from oosperm to completed metamorphosis. The effects of Aroclor 1254 on metamorphic development of X.

为了研究多氯联苯(Aroclor 1254)对非洲爪蟾变态发育的影响，将非洲爪蟾受精卵暴露在一定浓度0、400ngL^(-1、2μgL^(-1)、10μgL^(-1)，低于20μgL^(-1)的Aroclor 1254中，直至完全变态。

This discovery pushes it back tens of thousands of years into Africa—and suggests that the southern African coast may have been the site of a truly Promethean revolution.

The design of the stadium was selected from a series of concept designs ranging from acknowledgement of Johannesburg's disappearing mine dumps; the kgotla of the African city state; the African map as a horizontal representation, which included the roof as a desert plane supported on tropical trees set within the mineral wealth of Southern Africa; to a representation of the protea, South Africa's national flower.

The latest harvest has been dismal, bread may soon run out and famine is a real threat. African governments, though many are still pusillanimous, are turning against him. Mr Mbeki still waffles and wobbles, but opinion in his ruling African National Congress is hardening against Mr Mugabe.

原因在于，虽然他公然违抗，但他似乎承受着比以往更大的压力：国家经济情况恶化，年通货膨胀率达到百分之数百万；最近的收成不佳，面包也许会很快断挡，饥馑一触即发；许多怯弱胆小的非洲政府也与他作对；姆贝基虽然振振有词、犹豫不决，但是他的执政党非洲国家国会对对穆加贝的态度越来越强硬。
