联合国秘书长与1991年第一次海湾危机

1991年第一次海湾战争爆发前后,联合国秘书长佩雷斯.德奎利亚尔表现出色:首先,面对伊拉克武装侵略并占领科威特,作为联合国最高行政长官德奎利亚尔主持国际正义,从未怀疑过这样的武装侵略不应该被击退;其次,当联合国安理会武力制裁伊拉克的678号决议通过后,秘书长为寻求和平解决危机作了最后的斡旋努力;第三,海湾战争结束后,秘书长又积极组织了战争善后事宜尤其是人道主义的救援行动。德奎利尔所做的工作充分表明:世界不能没有联合国秘书长这样一个中立调停者、超国家利益代表的存在。     

物理新课程标准下的教学行为评价标准

物理教师的教学行为对提高学生的学科素养，确立科学的物理观和自然观起着十分重要的作用。它表现在教学活动的各个方面和教学过程的始终。随着新的物理课程标准的制定和实施，教师的教学行为以及对行为的评价也应作出相应调整，本文将就此进行初步探讨。     

虎纹蛙的食性与捕食行为的研究

通过养殖试验与野外观察相结合，研究了虎纹蛙（Hoplobatrachus rugulosa）的蝌蚪与成体的食性及捕食行为。结果表明，虎纹蛙是一种性凶猛的蛙类，喜食活的动物性食物，并具有互相残食的习性；在一定条件下，可取食不活动的食物；其捕食行为依蛙体与食物的相对位置而变化。

水性聚氨酯丙烯酸酯预聚物UV固化的涂膜性能研究

采用甲苯二异氰酸酯、双羟基化合物、二羟烷基羧酸和甲基丙烯酸羟乙酯合成了UV固化的水性阴离子型聚氨酯丙烯酸酯。用傅立叶红外光谱(FTIR)证实了该预聚物的结构，并讨论了羧基含量、原料不同配比等影响涂膜性能的因素；通过对涂膜吸水率、光泽度、硬度、拉伸强度等方面的测试，表明了合成的预聚物UV固化后具有良好的涂膜性能。     

发展中国海疆地理研究

中国既是陆地大国，又是海洋大国，即有陆疆又有海疆，中国拥有18000多km的大陆岸线，500m^2以上岛屿6500多个，依照《联合国海洋法公约》中200n mile专属经济区和大陆架制度，中国可拥有约300万km^2的管辖海域，在界定了海疆的概念基础上，提出中国海疆地理研究的范围、目的、意义和内容。

Disentangling prey-handling efficiency of larval newts through multivariate prey trait analysis

Multivariate prey trait analysis is a functional approach to understand predator–prey relationships. In the present study, six prey macroinvertebrate ecological traits were used to identify several key factors in the handling efficiency of seven predatory larval newt species. The results revealed a remarkable similarity in the feeding behaviour among species, suggesting a foraging behaviour convergence among species in the prey-handling efficiency of larval newts. Nevertheless, larvae of some newt species showed clear preferences for particular categories of ecological trait; for example, Lissotriton vulgaris tended to feed on macroinvertebrate taxa with random trajectory, and Calotriton asper fed on macroinvertebrate taxa with high agility. In contrast, Mesotriton alpestris showed a clear ability to feed on prey with movable accessories (cases/tubes) and patterned concealment. This study shows how multivariate approaches can complement traditional diet analyses, and the method has wide applicability across life-stages and species.     

Ecology and behaviour of the weaver ant Camponotus (Myrmobrachys) senex

Abstract

Weaver ants use silk produced by their larvae to build their nests. This behaviour is one of the more notable instances of social cooperation in animals; however, there are few studies of Brazilian species. This study investigated the ecology, natural history and behaviour of the weaver ant Camponotus (Myrmobrachys) senex in Brazil and showed that the weaver larvae have a fundamental function in nest building. The nests were always arboreal (one nest/plant), with a round form, beige in colour, and with leaves and shoots adhered to the silk nest. The average size was 34.24 cm and the average weight was 163.87 g; nests contained up to 50,000 individuals and several queens. Fusion and fission of colony parts were observed for C. senex. Worker ants were frequently observed feeding on honeydew, fruits and insects; and defended their territory. We suggest that C. senex larvae could be considered an effective caste, valuable in nest construction.
