AN EFFICIENT SYSTEM FOR LARGE-SCALE COLLABORATIVE TASKS IN GOVERNMENT


Vegetation Changes in the Permafrost Regions of the Qinghai-Tibetan Plateau from 1982-2012: Different Responses Related to Geographical Locations and Vegetation Types in High-Altitude Areas.

The Qinghai-Tibetan Plateau (QTP) contains the largest permafrost area in a high-altitude region in the world, and the unique hydrothermal environments of the active layers in this region have an important impact on vegetation growth.Geographical locations present different climatic conditions, and in combination kids PCA hats with the permafrost e

The axisymmetric Rayleigh waves in a semi-infinite elastic solid

ABSTRACT: It is well-known that Rayleigh wave, also known as surface acoustic wave (SAW), solutions in semi-infinite solids are plane waves with signatory properties like the distinct velocity and exponentially decaying deformation in the depth.Applications of Rayleigh waves are focused on Toys the deformation and energy in the vicinity of surface

Design and Interlocking Stability of Slope Protection Block of H-Type Gravity Mutual-Aid Steel Slag Core Concrete

At the present, the natural stone used for traditional block rock revetment is becoming increasingly scarce, and other commonly used revetment types also have some problems, such as hair mask poor stability, complex fabrication and installation process, and large investment.Therefore, it is imminent to study a new type of reinforcement of dangerous
