The inventory of this flora showed the existence of 70 species among which 48were exclusively detected at the Kasbah of Mehdia, 11 other species were only discovered at the Kasbah of Kenitra and 11 vegetal species were inventoried at both Kasbahs. These plant species are divided into 28 families. Four families clearly dominate the flora inventoried at both Kasbahs of the Gharb region. These are the Asteraceae (15.7%),Poaceae (10%), Apiaceae (8.6%) and Scrophulariaceae (5.7%). These families alone account for 41.4% of the specific size of the flora of the studied sites. The most dominant vegetal type is the therophytes with 61.4% of the total specific size, followed by hemicryptophytes with 17.1%. Located at the top or the base of walls, these plants, fitting into joints or cracks, have a chemical action on the stones by acids which they release and also have a mechanical action on the stones by the growth of roots inside cracks. This vegetation remains one of the most important biological factors of the degradation of historical monuments.展开更多

The Caucasus axis and higher massifs are built of granitoid, gneiss, and metamorphic shales. The oldest rocks (600 million years old) are found at the highest points and the age of the rocks decreases in the vicinity of the hypsometry steps (70 - 30 million rocks). The geological structure of the region has made a significant contribution to the formation of relief landscapes. Karst, erosion-denudation, volcanic, periglacial relief, and various interesting forms are formed here: caves, valleys, canyons, glacial and rocky lakes, waterfalls, deep valleys, mineral waters, and more. The peculiarity of the relief also influenced the mining geological history (5000 AD) and the creation of ancient settlements. Here, still in ancient Racha, at the head of the main river, Rioni, ancient settlements were formed due to iron, gold, and copper metal, which is confirmed by archeological monuments.展开更多

Jethawanarama Complex, one of the valuable sites in the country, is suffering from deterioration due to weathering. Monuments were built mainly from stones （granitic gneiss and marble） and clay bricks. The present study aimed to categorize weathering forms and interpret the recently-developing weathering processes. The growing of lichens on surfaces and the development of saline conditions are the major threats on the survival of monuments other than the typical weathering processes of tropical climates Morinite （NaCa2Al2[PO4）]2 [F,OH]5·2H2O） is identified as a weathering product of monuments and is generated from lichens.展开更多

Culture and art buildings were built in Bukhara and around its territory. Ancient Bukhara turned out as one of the biggest centers of Middle East in the period （era） of outstanding Somoniy （in the IX-X centuries） and Temurids （in the XIV-XV centuries）, particular, its developed literature, culture, architecture, and music art; especially, as being the capital of dynasty Mangits （at the beginning of the century XVIII-XX）, served as the groundwork of forming Shashmakom samples in groups. This time among a number of poets and artists, lived Akhmad Danish--the most mature scientist, philosopher, poet, calligrapher, and painter, Abdurauf Fitrat--poet and writer, theoretician, musician and political activist.展开更多

The palace located on an ancient water pond at the eastern side of Egyptian gulf besiding Sultan Bebris Al-Bondoqdary mosque is a place also called “Prince Qraja al-Turkumany pond”. That pond had been filled down by Habib Sakakini at 1892 to construct his famous palace in 1897. The integrated geophysical survey of the palace allowed the identification of several targets of potential archaeological and geotechnical engineering interest buried in fill and silty clay in the depth range between 100 - 700 cm. the methodological development focused on Multi-Fold (MF) Ground Penetrating Radar (GPR) imaging and subsurface characterization based on integrated velocity and attenuation analysis. Eight hundred sqm of Ground penetration Radar (GPR) profiling have been conducted to monitor the subsurface conditions. 600 meters are made in the surrounding area of the Palace and 200 sqm at the basement. The aim is to monitor the soil conditions beneath and around the Palace and to identify potential geological discontinuities, or the presence of faults and cavities. A suitable single and dual antenna are used (500 - 100 MHZ) is used to penetrate the desired depth of 7 meters (ASTM D6432). The GPR is used also detect the water table. At the building basement the GPR is used to identify the foundation thickness and soil-basement interface. As well as the inspection of cracks in some supporting columns, piers and masonry walls. The GPR also was used to investigate the floors and ceilings conditions and structural mapping. The results were validated by the geotechnical and structural surveys. All these results together with the seismic hazard analysis will be used for the complete analysis of the palace in the framework of the rehabilitation and strengthening wor展开更多

Such operations are even more complex whenever a portion of an ancient city is involved. This essay describes the redevelopment project of the historic center of Wuhu through the different themes raised during the drafting of the project： from the cultural opportunity of a wide reconstruction work, to the definition of the main design strategies, and the question of memory and identity. The results show that the field of intervention in this project is broader than that of most restoration projects, that is, an evolving city center, which is impossible to consider with traditional restoration parameters or with pure conservation. The only possibility of interven- tion is on the city structure, which allows the city to develop itself continuously within a welt- defined system of rules.展开更多

Those ruins exist today in two principal forms. The remains of the original townsite have been evacuated and opened to the public as an open-air memorial; and earthquake museums have preserved artifacts recovered from the townsite and organized them alongside supporting texts, images, exhibits, dioramas, and amusement attractions. The ghost town, it is argued, ruptures the reform-era sense of national progress and development, forcing its observers and participants to acknowledge loss and absence. Connecting to a wider discourse, the National Earthquake Memorial Museum （NEMM） attempts to piece that sensibility back together by creating a particular memory of the massive state-led relief effort, by ＂disciplining＂ the catastrophe through inquiry and education, and by sublimating the earthquake through science, planning, and building. Although they remain emotionally separate, the ruins and NEMM have a natural tension with one another. Away from the epicenter, the privately managed Wenchuan Earthquake Museum （WEM） combines ruins and narrative to capture the ＂strange objectivity＂ that comes from any effort to make sense of what is ultimately insensible.展开更多
