Abstract; The present work provides a revision of the Xeroplana genus from Tunisia on the basis of historical, morphological, and anatomical data, Distribution maps of this genus are presented for the first time. The anatomy of genital organs of all recorded species and classified under this genus are presented. And a new description of the genitalia of Xeroplana zeugitana is presented. For each species described, a synonymy list of names is provided and all cited specimens are illustrated.

Abstract: Achieving of the food security is one of the most important economic problems that threaten economic and social development in Egypt, through the imbalance between supply and demand, thus the occurrence of a food gap due to the increase in food demand as a result of the increase in the population growth rate, in addition to the inability to increase agricultural production to meet the increases demand of food. The inability of production to meet the growing needs leads to increases the imports of crops and food commodities, and an increase in the deficit in the Egyptian trade and agricultural balance. The cereal crops are the most important strategic crops for achieving food security and meeting the needs of the population in terms of demand for them. The agricultural production of these crops is affected by climatic changes by negatively effect of agricultural production (CAPMAS). In this paper we examine how the Climate Change affected on the rice productivity in Egypt, with the aim of determining the extent to which productivity has changed due to climate change in Egypt, using the Autoregressive Distributed lagged (ARDL) methodology, where it was found that there is an inverse relationship between climate changes and the rice productivity. The results indicates that a similar negative impact of the maximum temperature change on the rice productivity in the long term, which is consistent with an economic theory.

Annotation. The article Fergana Valley soils were protected lands until the beginning of our century, and were developed at a high speed by digging the Big Fergana, Southern Fergana, Okhunboboev and other canals. The construction of large inter-farm reservoirs has reduced the level of water. The salinity of large salt marshes and highly saline lands has decreased to moderate or low salinity. However, the development of Fergana hills and desert massifs leads to the expansion of the area of saline lands in Central Fergana.

From Design to Appreciation and Value: An Exploration of Cultural Connotation Based on Art Education (Part 2)

Xiao Chen

Guangzhou University, Guangdong, China

Abstract: Art education is a process in which intuition, feeling, association, imagination, expression, creation, design and other perceptual and rational thinking blend together. Art education can stimulate and strengthen people's creative impulse, and cultivate and develop people's aesthetic intuition and imagination. The initiative, the opposite sex, the self-creation, the intuitive acuity and the internal logic in the creation of art education all influence the cultivation of people's comprehensive quality imperceptibly. In the cultural system, fine art is a branch of the art class and also a means of cultural transmission. It is constantly developing with the change of social form, the deepening of human cognition, the progress of history and the development of culture. Subject foundation of art is to establish the fine arts education in the fine arts education of fine arts orientation, the status of the art is very outstanding, thus art culture in the spread and development, has become the main pursuit of the goal, "easy on the copulative", said: "is it XingErShangZhe call, XingErXiaZhe calling." In order to compare the internal relationship of art education, art itself is called "instrument", education effect is called "Tao", first recognize "instrument" after "Tao", from "Tao" to talk about "instrument" is blind, the realm is not high, not far; From the "instrument" said "the way" is mysterious, empty drift, lack of foundation. Therefore, art education should not be confined to the purpose of art itself, otherwise, the status of educational discipline will be questioned. The effect of art education is based on art. In other words, the goal can only be reached by means. Without concrete means, the goal can only become a fantasy.

Abstract: In this article, different precipitation characteristics in three basins where the formation of the Amudarya River flow takes place: namely, the    Surkhandarya River basin, basins of the Tajikistan rivers, basins of the northern part of Afghanistan are considered. Their role as flow-formation factor is investigated. Correlations between precipitation distribution over absolute elevation are derived, average precipitation totals are calculated for precipitation falling on these basins. Correlation between the Amudarya River flow in the Kerki cross-section and the average precipitation totals in the Surkhandarya River basin is derived, and it was used for calculation of the river flow in Kerki.
