This document presents an extension of the multiple factorial analysis to symbolic data and especially to space data. The analysis makes use of the characteristic coding method to obtain active individuals and the reconstitutive coding method for additional individuals in order to conserve the variability of assertion objects. Traditional analysis methods of the main components are applied to coded objects. Certain interpretation aids are presented after the coding process. This method was applied to poverty data.

The Arctic hosts an extraordinary wealth of terrestrial fossil biotas of Late Cretaceous age representing a diverse and highly productive near-polar ecosystem that has no modern analogue. Compared to the rest of the Late Cretaceous Maastrichtian plant diversity was at its lowest and the temperature regime the coolest,yet the semi-open forests supported a rich dinosaur fauna made up of a wide range of body sizes and feeding *** combination of mild winter temperatures and continuous darkness lasting several months imposed severe constraints on primary productivity. Plant survival strategies involved almost universal winter loss of foliage,which in turn limited food supply for non-migratory overwintering herbivorous animals. A combination of leaf form and tree ring studies has been used to quantify year round variations in temperature and determine the timing of spring bud-break and autumnal leaf fall. While Maastrichtian winter temperatures were cold enough( down to- 10℃ for brief intervals) for frequent frosts and snowfall,summer temperatures were cool but highly variable and at ~ 83 ° N along the north Alaskan coast frequently fell below + 10 ℃. Theropod egg shell fragments at ~ 76 ° N in the Maastrichtian of Northeastern Russia may indicate that dinosaur reproduction took place in the Arctic ecosystem,as distinct from taking place at lower latitude breeding grounds reached by *** raises the question of nest management and specifically the maintenance of incubation temperatures,and the duration of incubation. Of critical importance to year-round residency is the timing of hatching and juvenile care before winter darkness set in,temperatures fell to near freezing and food resources became limited.

从正要准备大满贯决赛的世界第一到正要参加自己第一次网球课的孩童,热身都是训练中最重要的一环。就像早上开车时要热车一会儿以保护爱车一样,我们的身体也需要慢慢的启动。好的热身活动能有效地降低受伤风险肌肉强度随着体温升高下降,同时肌肉柔韧性逐渐提高肌腱更有弹性,肌肉更有韧性,它们断裂和撕裂风险就会降低关节充分得到润滑也能有效降低脱臼和扭伤的风险软骨更有弹性从而能更好的应对冲击神经系统负责传递预判和移动方向。随着体温的升高球员的协调性也会提高从而降低动作变形和摔倒风险的产生。
