The paper deals with the question of Holocene transgression on the southern plain of the Changjiang *** the beginning of the transgression, the paleovalleys of the Changjiang and Qiantang Rivers were covered by sea water at *** shoreline of 8000-7500 yr BP coincided with the -7m isobath of paleotopography. Sea level had already been the present level about 7000-6500 years ago, and the Holocene transgression reached its maximum extent. During the period, the Changjiang and Qiantang Rivers and the Dongtiaoxi valley were turned into estuaries; the eastern area of Shanghai became a shallow sea; some of the bays and lagoons were distributed on the Hang-Jia-Hu and Tao-Ge Plain; the hilly region around the Taihu Lake was coastal marsh and freshwater swamp. Gangshen on the west of Shanghai was formed 7000-4000 yr BP, and during the last 4000 years, the eastern coastal plain of Shanghai advanced quickly toward the sea, and partial clear land of the western Taihu Lake was enclosed and charged into a fre

Pakistan is predominantly a mountainous country where rural development activities are characterised by inconsistency, politically motivated short-term projects without proper feedback. Since the inception of the country, the top-down approach has been followed, and the same development plans that were formulated for the plain areas have been extended to the mountains without any modification. In doing so, neither the participation of the local communities was cared for, nor the mountain specificities were considered in the planning process. Moreover, the representation of the local inhabitants was improper and contradictory to the facts. This biased approach has been one of the main causes for the failure of development projects carried out by different agencies of the Government. Contrary to the perception of the state authorities, the mountain communities proved to be more open to accept new approaches and demonstrated the capacity and capability of being a dependable development partner. In this paper, a detailed account of the Aga Khan Rural Support Programme （AKRSP） has been presented to assess and evaluate the approach followed by this non-governmental organisation （NGO）, and the response of the local inhabitants as collaborators in the development process. The achievements of the AKRSP from project planning, implementation and monitoring can be adopted as a model for rural development not only in the plains, but also in the mountainous areas of the developing countries in the world.

Geomancy has long been neglected in the geographical circle in China because it was simply treated as superstition and its geographical value was not recognized correctly So, from the angle of geography (both physical and human geography), this treatise analyses the geographical thoughts and value of geomancy, expounds the relationship between it and the ancient Chinese geography and makes the former position in the latter clear It is pointed out that: (1) There were two levels of geographytheoretical geography and applied geography, and three main cluesofficial geography, scholar's geography and folk geography in the development of ancient Chinese geography (2) However, although usually interacted, the above three main clues of the ancient Chinese geography had their own specific features respectively and had never become a synthetic geography (3) As to geomancy, it existed among all these kinds of ancient Chinese geography, but mainly belonged to the level of applied geography and was embodied in the folk geography essentially (4) There were plenty of geographical thoughts in geomancy, especially in the respect of practice It had special, unreplacable effect on the transformation of the natural landscape and creation of the human landscape in China

＜正＞Results from both theoretical and experimental investigations on laminated epoxy composites reinforced with plain weft knitted carbon fiber fabrics of different arrangements subjected to fatigue loads are presented in this paper. The stacking sequences used are [0/0/0/0], [0/45/-45/0], [90/90/90/90], [0/90/90/0], and [90/45/-45/90] where 0 refers to the fabric wale direction and 90 to the course direction. Tensile fatigue with stress control was applied to the laminates as well as to the monolithic matrix material, with a stress ralio of R=0.1 and a

China is a country with many nationalities. Each of them has formed its own special culture, which is different from the mainstream of majority Han nationality, by adapting to geo-environment during history. Due to different backgrounds, the regional developmental model of minorities in the western China is different from the Han nationality and western countries. Combining a knowledge-based civilization and sustainable development, the minority areas can seek the systematic integration of culture-economy-ecology. Based on this, the paper suggests that the minority areas in western China should take the way of emphasizing developmental quality rather than developmental quantity for a harmonious system of culture-economy-ecology. Some approaches for developing minority areas in western China have been put foreword.

Doping is a key technological process in materials science that involves incorporating atoms or ions of appropriate elements into host lattices to yield hybrid materials with unique properties and functions. For nanocrystalline materials,doping is of fundamental importance in stabilizing a specific crystallographic phase,modifying electronic structures of semiconductors,modulating magnetism of ferrites as well as tuning emission properties of ***,we present a doping principle that is
