SLOPE/W has become the widely used professional analysis software in the field of geotechnical engineering for slope stability analysis.
It includes a variety of methods (Morgenstern-Price, GLE, Spencer, Bishop, Ordinary, Janbu, Sarma, Corps of Engineering, Lowe-Karafiath) for geotechnical engineering problems such as the shape change of slip surface, pressure condition of pore water, soil property as well as different loading ways.

The acceleration of soil erosion, increased use of water resources, urbanization, and the over-exploitation of forest and grassland ecosystems has severely disturbed the normal structure and the mitigation function of the nation's ecosystem, even though a healthy environment provides many ecological services and lies at the center of natural regulation of the environment.
A new environmental reconstruction movement was initiated by the central government after those disasters; it was designed to control soil erosion, manage water resources and rebuild a stable ecosystem in a way that would provide long-term economic development [2].
The Guan-ting, Huai-rou and Mi-yun Reservoirs provide suitable habitat for water birds, wading birds, and birds of prey.
Combining these amateur bird observation data with professional field surveys would greatly increase the practical value of the GIS monitoring platform presented here and designed to document the variations in the distribution of key protected bird species across the landscape.

Introduction The laterite nickel ore is a very special mineral, a kind of mineral powder which is condensed with water.
In the process of transportation, if the ship suffers a storm, or the ship vibrates for a long time, it will result in the phenomenon that the mineral surface separates water out and appears "liquefaction flow" after the water content of ore is over 37.5%.
This also determines that the sensor nodes cannot be permanently installed inside the cabin, and every process of the demolition and installation requires the ship crew to operate, rather than a wireless sensor who knows the network knowledge or a marine shipping professional.

These inhibitors, known as anodic inhibitors, can function with presence of water vapour (high humidity) either with or without oxygen and effective as low as 0.1 gl-1.
In this practice which knows as “mandi” keris, keris owner will inhibit corrosion in keris using a coconut water [27].
Malay traditional has used coconut water to remove and treat corroded iron base object such as Keris blade.

.), · environmental factors (high air humidity, presence of vegetation, soil, water areas, prevailing winds, environmental load etc.), · maintenance and use factors (regular, cyclical maintenance and cleaning, structures changes, mechanical defects, additional mounting of structures as satellites etc.).
First sample without rinsing by power water and without mechanical cleaning has showed black deposits of biological material after 2 years.
The results are influenced by the "ecofriendly" chemical product (low environmental impact, water- dilutable, permitted flushing, low risk of soil contamination etc.).
These risks are mainly of absolute inactivity or lack of, professional misconduct of manager, owner, or user of ETICS.

Dong Jinlu synthesized a kind of water suitable foams of polyether polyols using four bromine alcohol as flame retardants, and got flame retardant PUF with the solid-liquid fuel agents in a complex system.
And then they put in the inorganic flame retardants, water-soluble adhesives, inorganic dispersants, intensity strengthening agent, water and foaming agent.

For example, the design of professional garment needs to reduce the weight of clothing, removing redundant off body parts to reduce the resistance of the movement.
Therefore, the underlay clothing generally selects materials which have good water vapor permeability and warmth retention property.
The research indicated that the sequence of the water vapor permeate speed of the clothing material is: RayonThe silk material generally used for underlay clothing has crisp handle and excellent water vapor permeability after craft processing.
