Franco and Thuja occidentalis L. seem to be of the same type, as based on the morphological study of the change in pollination drop, during the process of pollination. Entering the pollination drop, the pollen may alter the surface of the drop or reduce the secretion of the ovule with concomitant increase of evaporation. It has been further noticed that the dynamiechange of the drop withdrawal rate was closely associated with the different kinds of pollen received. It seemsthat the withdrawal of the pollination drop may be induced by pollen from plants consanguineous to P. orientalis, almost as effective as from pollen of P. orientalis itself and comparatively more effective than the foreignpollen received from distant plant species. The drop withdrawal could he mainly induced by the pollen that causes the reduction of ovule secretion.展开更多

Culture is China's spiritual handholds. In building beautiful villages, envi- ronment, public service facilities and infrastructure are so important. But the re- search stressed cultural inheritance ad spiritual civilization to make sure village beauty outside and inside. The aim is to explore cultural inheritance models in ec- onomy, living and eco-tourism, with a case study of Xuwan town.展开更多

Seventeen half-sib families and 42 full-sib families ofL. vannamei were produced using artificial fertilization from 2-4 dams by each sire, and measured at around five months post-metamorphosis. The results show that heritabilities among various traits were high: 0.515±0.030 for body weight and 0.394±0.030 for total length. After one generation of selection, the selection response was 10.70% for offspring growth. In the 5th month, the realized heritability for weight was 0.296 for the offspring generation. Genetic correlations between body weight and body size were highly variable. The results indicate that external morphological parameters can be applied during breeder selection for enhancing the growth without sacrificing animals for determining the body size and breed ability; and selective breeding can be improved significantly, simultaneously with increased production.展开更多

It has received much scholarly prominence in the Western world, and perceived as an emergent art of European origin. What has been given little or no scholarly attention is the African essence of root of conceptual art movement. This article addresses the historical epochs of conceptual art in Africa and delves into the critical question of whether or not conceptual art is an emergent art in Africa. With the help of the images of African artworks, this article attempts to fmd visual answers by examining the art-historical account of the art through visual analysis in simple narrative format in telling the African side of the story. It concludes that the adoration and idolization of Marcel Duchamp as the father of conceptual art is contestable since the art was many centuries old in Africa before the twentieth century artists began to practice it in the West. Duchamp's attempt at dematerialization of art, and showing distaste to the traditional aesthetics of Western art at the time through conceptual exploration had been in practice in African art and, therefore, not an invention.展开更多

Values are important components of a given culture accepted by individuals sharing that culture. They are deep and hidden elements of the cultural iceberg that are seldom questioned or defended but can reflect different characteristics of different cultures. Kluckhohn and Strodbeck's value model is used here to analyze distinct Chinese and American culture.展开更多

But behind this veil, ethnofugalism can be found by way of analyzing their conversations and behaviors. This paper tries to see their attitude towards their mother tongue and their own cultural tradition. It holds that no culture is inferior to others, which is the base on which intercultural communication is built.展开更多
