., Pipetronix Gmbh, Trapil, H Rosin Engineering Gmbh, and British Gas (PII) etc.[9] · GEL PIGS Gel pigs are a series of gelled liquid systems which have been developed for use in pipeline operations, either during initial commissioning, or as a part of a continuing maintenance program.[6] Most pipeline gels are water-based, but a range of chemicals, solvents, and even acids can be gelled.
· Extremely effective in removing liquids from product pipelines · Removes condensate and water from wet gas systems and controls paraffin buildup in crude oil systems

Meanwhile, it had non-disastrous weather, low population density at that time, and near the load Center, have a good fresh water resources which means water intake and drainage is convenient.
The basic decision-making power rests in the hands of the government and its departments; decision-making is independent running in closed administrative procedures, relying on expert advice, the analysis of the professional and technical personnel, and the decision of the Chief Executives.

The wind influences the building: structural of the building, its façade structural and non-structural parts, airtightness of the openings, water tightness [5], etc.
Basically, all simulations in the hand of non-professional users is, but with CFD differences from reality are often 2 - 5 times [7].

It is applied extensively to water resource conservation, soil and water loss, the evaluation of forest quality and the construction of forest landscape etc.[2-4] There are a lot of methods to monitor the canopy density and understory light environment including the calculation of canopy projection, looking upwards to the sky, the use of measuring equipment for canopy density and the technology of 3S etc.[5].
Hemispherical photography is also known as the “fisheye lens” method, which uses high resolution professional digital camera and fisheye lens of ultra-wide field to obtain hemispherical digital imaging for the research of plant canopy structure.

(3) Several new and complex separation unit operations (such as GLMC) are not available in professional process simulators.
The regenerated solvent remains in a closed loop, returning to GLMC modules after make-up of water and MEA.
The top product of the stripping columns is water saturated CO2 (40ºC, 2 bar).
Cooling water at 30ºC is used in the shell-side of intercoolers with thermal approach of 15ºC.
Cooling water consumption in shell and tube heat exchangers is of 134,911,200 kg/day.

The routes, roadbeds, bridges, tunnels, interchanges, facilities along the lines and other professional projects involved in highway design are closely related to highway land use.
Earth borrow should be combined with water conservancy construction, such as river improvement, lake cleanup and farmland irrigation facilities.
Earth borrow is better combined with the transformation of farmland, the construction of water conservancy, the excavation of fish breeding or lotus cultivation ponds and the development of aquaculture industry.

Introduction The professional building structure identification organization usually utilizes correlation equations of PBD fire code to verify design safety for building structure, and fire damage examine tables or experimental investigation to determine building structure safety for building after a fire.
Concrete material is constituted with cement, sandy soil, aggregate and water to cement by hydrate.
The general strength concrete compressive strength lost 6 - 10 % in temperature reached 100 ° C and the rise again 9 - 14 % between temperature reached 100 - 200 ° C due to the water of small hole in the concrete disappearing increase concrete structure friction and aggregate reciprocal locking strength.

Readiness for and response to radioactive emergency incidents in emergency planning zones are addressed in professional publications by the International Atomic Energy Agency (IAEA) [7], [8].
Basic physical attributes of building materials can be divided into five basic groups: - Attributes related to fire safety:heat resistance, stability in fire, thermal expansion, thermal conductivity, accumulation capacity; - Attributes related to protection against mechanical stress: strength in compression, traction, slide, bend and torsion, elasticity and pliability, hardness; durability; wear and tear; - Attributes related to protection against water effects: absorption, humidity, diffusion, capillarity, water resistance, frost resistance; - Attributes related to protection against sound: air and step attenuation, speed of sound; - Attributes related to protection against permeability of dangerous substances: surface density, bulk density, compactness, porosity.
