In this exercise, XPS (0.035 W/(m2.ºC)) was used as insulation material. 3,6 m 27 m 7,15 m m Figure 1 – Sketch of the building analyzed.
Since each interface between materials (concrete, glass and insulation) is a node with a predictable heat flow, it is necessary to include equations for its calculation.
k, cpm is the specific heat capacity of material k, xik is the thickness of material k (concrete or glass) of surface i, Tdp is the dew point temperature, Tcom is the comfort temperature, λk is the thermal conductibility of material k, is the indoor air temperature at time instant t, xiins is the thickness of thermal insulation of opaque element i and is the indoor superficial temperature of surface k at time instant t.

Precipitate Phases in Normalized Ferritic/Martensitic Steel P92 Zhiqiang Xua, Yinzhong Shenb*, Pengcheng Zhuc and Wenwen Liud School of Mechanical Engineering, Shanghai Jiao Tong University, 800 Dongchuan Road, Shanghai 200240, China azhiqiang789@sjtu.edu.cn, b *shenyz@sjtu.edu.cn, czhupengcheng_sjtu@126.com, dwenwenliu_sjtu@sina.com Keywords: Precipitate phases; P92 steel; Normalization; Transmission electron microscopy Abstract.
Therefore, the P92 F/M steel is a promising structural material in Generation IV nuclear energy systems [5].
Experimental Procedures The test material studied in the present investigation was a commercial P92 F/M steel without service.
It is widely accepted that sigma phase would cause substantial damage to ductility, toughness and corrosion resistance of steel materials [14].

Introduction Low-dimensional nanostructured wide bandgap (Eg > 3 eV) semiconductor materials have attracted tremendous attention as building blocks for UV photonic devices [1- 4] such as UV photodetectors, phototransistors, and photodiodes.
In this study, very practical and cost-effective nanowire device fabrication scheme has been followed utilizing catalyst-free grown high quality AlN nanowires, which is key to achieve high performance photosensing devices.
Further, low voltage operation could enable new application opportunities of these devices particularly in deep-UV photonic applications, which has been suffering due to the lack of high quality ultrawide bandgap semiconductor materials.

Introduction In times of increasing raw material costs, a consequent lightweight construction is getting more and more focused On the one hand, with lighter technical systems, less needed material guarantees a cost-efficient production.
By this increasing of the integrated functions, the overall number of parts can be reduced and thereby also the required material decreases.
By its three dimensional material flow a selective forming of highly complex structures in only a few forming steps is possible [2].
In order to ensure a sustainable production as well as a further reduction of material requirements, a production related quality control loop is needed.

The Aluminum alloy EN AW-5083 (AlMg4.5Mn0.7) was used for all tests as sample material with a sheet thickness of 3 mm.
Severe material accumulations can be found orthogonal to the impact groove.
A predominant part of the kinetic energy is not available for plastic deformation of the material.
This results from the much higher energy input into the material compared to the wire based tool.

Table 1 presents detailed information about all tested configurations and it is worth noting, that the material of both shafts and bushings were the same for all tested configurations and that only the surface treatment was modified for shafts (nitro-carburized and oxidized or no treatment) and bushings (no treatment or surface modified).

This creates a microstructure with very small and spherical grains, and consequently a material with high mechanical strength, but with very low fracture toughness.
Materials and methods Commercially available α-Si3N4 powder (M11, H.C.Starck, Germany), Al2O3 powder (Baikalox CR-10, Baikowski Chimie, France), Y2O3, La2O3 and Yb2O3 powder (with purity higher than 99.9 %, Aldrich Chemical Co, USA) were used in this study.
On the basis of these curves one may conclude that introduction of intermediate plateaus at temperatures related to the maximum shrinkage rates, leads to improvement in the final density of the materials that have been studied here.
