Aeolian sand widely exists in the desert of western China. The reinforcement aeolian is considerable significance to construction transmission lines desert. In order study impact different cement contents and moisture content on performance cement-stabilized sand, 18 types samples with water were prepared. confined unconfined compression tests conducted TSZ series automatic triaxial instrument....

After the construction of desert highway, physiognomy changes caused by surface wind erosion and accumulation not only seriously threaten stability road structure, but also have a tremendous impact on safety highway operation maintenance work highway. The purpose this paper is to explore change sand sedimentation law transport along in moving dune areas, clarify flow formation mechanism damage ...

Wind regime and sand grain size are two of the factors that determine the morphology and dynamics of sand dunes in desert areas. Regarding the importance of wind effects on sand dunes especially in Iran, in this study, Khartooran Erg was analyzed to determine wind direction and to detect sand source sites. Khartooran Erg is located on eastern north of Iran and lies in Khorasan Razavi and Semnan...

apart from other aspects, desert is a natural environment and is one of the appealing terrestrial elements. putting its symbolic and fictional senses aside, the term “desert” bears mystic sense more than material sense. in addition to the worlds materialistic experiences, desert has attracted the attention of writers because it creates a kind of inner experience, which returns the individual in...

Sicarius and Homalonychus are unrelated, desert-dwelling spiders that independently evolved the ability to cover themselves in fine sand particles, making them cryptic against their background. Observations that particles associate with these spiders' setae inspired us to investigate the role of setal microstructure in particle capture and retention. Here we report that Sicarius and Homalonychu...

A polyphasic taxonomic approach was used to study strain 12116T, which was isolated from desert sand in Xinjiang, China. Cells of the isolate were Gram-negative, non-motile, rod-shaped and aerobic. MK-7 was the predominant respiratory menaquinone. The DNA G+C content was 46.3 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate was most closely related to the m...

The massive dune sea of the southern Namib Desert is approximately 800 km in length and some 140 km wide. These dunes are among the highest in the world and, in spite of very sparse vegetation cover, they support a surprising variety of reptiles and arthropods (Koch, 1961; Louw & Seely, 1982). A feature of the arthropod fauna is the high species diversity of flightless tenebrionid beetles. Thes...

The efficacy of three suction traps for trapping phlebotomine sand flies (Diptera: Psychodidae) was compared. Traps were baited with Co(2) and used without any light source. CO(2)-baited CDC traps were evaluated either in their standard downdraft orientation or inverted (iCDC traps). Mosquito Magnet-X (MMX) counterflow geometry traps were tested in the updraft orientation only. Both updraft tra...

Soybean-urease induced calcite precipitation (SICP) is an effective method for the improvement of sand, which forms a biocemented layer on desert sand surface to resist erosion by wind. Under this study, field tests were carried out determine how SICP approach may enhance resistance wind-induced and durability treatment in southeastern margin Tengger Desert, Ningxia Hui Autonomous Region, China...

Reaumuria soongorica and sand rice (Agriophyllum squarrosum) belong to the clade of Caryophyllales and are widely distributed in the desert regions of north China. Both plants have evolved many specific traits and adaptation strategies to cope with recurring environmental threats. However, the genetic basis that underpins their unique traits and adaptation remains unknown. In this study, the tr...
