There are Harbin Industry University, Harbin Engineer University and other 63 universities in Heilongjiang Province, every school has at least 200,000 graduates every year.
The quick development of information technology, soft technology, biological technology, new material, new energy is triggering a new industrial revolution, producing new productive manner and economic morphology and enhancing the development of the service outsourcing.
Domestic service outsourcing enterprises also exist between the fierce competition, many domestic provinces and cities in the development of service outsourcing transformation of economic development as a key task, such as Xi'an issued a "Declaration of Xi'an service outsourcing"; Jiangsu Province scored in a three service outsourcing base in the province and then places an additional provincial "service outsourcing base cities" domestic outsourcing market is highly competitive.

Nanotechnology has revolutionized the world with tremendous advancements in many fields of science like engineering, biotechnology, analytical chemistry, and agriculture [6].
Their characteristics are similar to their parent materials since they are recently developed.
It cannot go finer than this size, due to the hardness of some materials in the volcanic ash.
Application of volcanic ash results in breakdown of easily weatherable silicate minerals present in pyroclastic materials like volcanic ash [15].

Effect of Concentration and Loading Fluid of Nanofluids on the Thermal Resistance of Sintered Powder Wick Heat Pipe Nandy Putra, Wayan Nata Septiadi, Ridho Irwansyah Heat Transfer Laboratory Department of Mechanical Engineering, University of Indonesia Kampus Baru UI, Depok 16424, Indonesia nandyputra@eng.ui.ac.id Keywords: heat pipe, nanofluids, sintered powder wick.
The performance of heat pipes can be affected by several parameters, such as heat load, type of material, porosity and permeability of the wick, the type and amount of working fluid and the geometry of the heat pipe.
Do et. al [10, 19] presented that the key effect of heat performance improvement of a heat pipe is not only on their thermophysical properties of nanofluids but the larger is the thin porous coating layer formed by the nanoparticles on the surface of nanofluids in heat pipe wick.

The lateral buckling of steel-concrete composite П-beam1 Lizhong Jiang 1, a , Linlin Sun 1, b , Xing Li 1,c 1School of Civil Engineering and Architecture, Central South University, Changsha, China a lzhjiang@mail.csu.edu.cn, bslinlin1024@163.com , ccsulixing@126.com Key Words: steel-concrete composite beam, lateral buckling, buckling model, critical moment Abstract: Based on the theoretical analysis of steel-concrete composite П-beam's lateral buckling, the computing model and simplified computing model on the stability of composite П-beams are brought forward.
Buckling model of composite П-beam To get the analytical model for П-beam' lateral buckling, the assumptions are given as follows: (1) The isotropic material is perfectly elastic, component is the uniform cross-section beam and (2) The effect of bending deformation at plane before buckling on lateral buckling should not be taken into account, because the beams' flexural rigidity at bending plane is very large
