(2) The Kc,a values and respective data used for calculating Kc,a are listed in Table 1 and 2.
The experimental data do not allow to separate the effect of exposure time at high temperature in vacuum on Kc,a.
However, the annealing in vacuum resulted in a change of the color of the TBC from white into grey, which is a well known effect due to partially reduction of the ZrO2 into ZrO.
This change was accompanied by a reduction of the TBC hardness.

Introduction Magnetic film plays an important role in various advanced applications, such as micro and nano-electromechanical systems (MEMS, NEMS), electronic sensors, and magnetic recording head cores in data storage devices.
The composition and thickness data of each specimen was used for weight calculation.
%Fe, is the critical grain size, above which the coercivity is reduced due to the reduction of pinning sites for magnetic domain wall movement [14, 15].
The saturation magnetization of the thick films is relatively high and increases with a reduction of the Fe content.

Improvement levers are presented for impact reduction and comparison between alternative and conventional water treatment process.
The overall reduction of the electricity used in the system will reduce the environmental burdens of the system and will result in an improved environmental performance as measured by the LCA.
Parameters involved in the entire product life cycle will be obtained from primary and secondary data.
Parameters involved will be obtained from primary and secondary data.
To date, there are available numerous approaches towards the life cycle Impact assessment (LCIA) which can be used including with the help of software programs that enable users to develop, store, analysed and exchange vast amounts of data related to products, services, processes, and their respective impacts.

At the design stage, where the reduction of environmental load is most effective, building LCA techniques could be easily carried out to support proactively environment-friendly decision making of designers as well as the designs of environment-load-reduction-type buildings.
Furthermore, to add and supplement the details of the finish materials used in the apartment buildings, the finish material types of apartment buildings from “2006 Apartment Building Construction Cost Analysis Data” published by the Korea Land & Housing Corporation (LH) are added.

X-ray diffraction (XRD) data were collected using the X-Pert Philips diffractometer equipped with a curved graphite monochromator on a diffracted beam.
These results suggest high content of molybdenum in the obtained nickel-molybdenum alloy coatings according to literature data which show that such a microstructure of the Ni-Mo alloy with open pores and cracks is characteristic for the nickel-molybdenum coatings containing more than 15 at.% of Mo [1,11,12,14,16,20].
Based on the obtained results and literature data it should be stressed that acidity is an important parameter influencing the co-deposition process of nickel and molybdenum.
At the cathode surface simultaneously different processes occur like reduction of Ni(II) ions: , (3) discharge of Mo(VI) complex ions: , (4) , (5) , (6) , (7) and HER.
The co-deposition of Mo can stimulate to a certain degree the reduction of Ni(II) ions what is due to the decrease in free energy during formation of the Ni-Mo alloy.

The respective magnitudes for spacings are taken from experimental data [5] for CFRP cross-ply laminates [01/904/01] shown in Fig. 1.
Such high values of reduction in stiffness can lead to catastrophic failures of structures if only averaged distributions of defects would be used to predict the load carrying capacity. 0.102 0.107 0.112 0.117 0.122 0.127 0.132 0 0.05 0.1 0.15 0.2 0.25 0.3 0.35 0.4 Delamination size (mm) Displacement (mm) Maximum Average Random Minimum Fig. 4.
The number of data points generated is equal to the number of nodes in the layer of cohesive elements and assigned to all the nodes in the cohesive layer of the finite element model.
The results obtained show high values of reduction in stiffness of the considered beams compared to the undamaged one.
Results of number of realizations underline the need to account for the microstructural randomness since predictions based on the uniform or mean properties data for these laminates could significantly overestimate the critical value of stress necessary to initiate material's damage/fracture.

Research of Mechanism So far, the main views about the mechanism of low-frequency vibration cutting can be summarized as follows [2]: (1)Reduction of friction coefficient Many scholars believed that low-frequency vibration cutting could reduce the friction coefficient between cutting tool and workpiece.
The reduction of friction coefficient finally improved the cutting effect
They did a comparative analysis between low-frequency vibration cutting test data and ordinary cutting test data.
They analyzed the contrast data of low-frequency vibration turning and ordinary turning.

The data was analyzed by the software provided by the instrument’s manufacturer.
A commercial dust meter was used to measure particulate matter concentrations in indoor air, and the data was analyzed using the instrument’s software.
The data was compared with a recommended value as shown in Table 2.
As the students left the lecture theatre after the lecture session at 1400 hrs, the temperature gradually dropped due to instant reduction in heat gain from people.
That was because occupants let the door open widely for easy exit and as a result fresh air infiltration caused reduction in the CO2 content.

Several studies reported that job redesign and ergonomic interventions lead to improvement in safety, increased job satisfaction [19] and reduction in musculoskeletal disorders [20].
Behavioral preventions can be successful only if they decrease exposure to hazards; do not include components for hazard exposure reduction [18].
In performing our work, we used statistics as gathered for each year by the GUS in Poland, based upon the Z-10 form used to study work conditions in companies that employ minimum 10 employees [24] and data concerning structural changes groups of national economy companies, gathered based upon the RG-1 form [25].
Based upon data concerning the number of persons in case of whom appropriate preventive means were used and the number of persons in case of whom it was found that risks occupational hazard risks had been eliminated or reduced, the level of use of given technical means – ST, organisational means – SO, and personal protection means – SI was identified in %, assuming that preventive means could have been used independently of one another.
