Unlike sitting position, in orthostatic posture the disadvantages manifested upon the human body are more ample and involve all the structures of the human body: impairing blood circulation in the entire body especially at lower limbs level; difficulties in maintaining balance; weight of the body is distributed on a small area; cerebral effort is amplified due to the necessity of maintaining balance of body in vertical position; accuracy of upper limbs is lower; if the posture is maintained for a long time it may lead to deformations of the bones, disorders of the vascular system and at internal organs level. [1], [2] Professional literature mentions that orthostatic position is to be avoided most of the times in organizing any work place even if the equipment or work plane is adapted for every difficulty degree of the activity (fig.1).

Among those, the typical methods includes Equivalent Coefficient Method, life cycle environmental impact assessment and analysis of using professional software [12,13].

Besides other relevant factors, there will be taken into account the location of emission sources, the nature of professional activity, the direction and size of air currents, the presence of other particles that might influence the measurement results.
In fact, it is virtually impossible to follow the progress of nanoparticles in the environment and there is no way to remove them from air, water, soil, which could possibly bio-accumulate in the food chain.

Despite record profits in the OG sector, worldwide R&D activities related to welding are in the automotive far more visible in professional societies, local, national and international conferences, well indicating that welding R&D expenditures in the automotive greatly exceeds those from the OG sector.
In Figure 1 is shown that carbon steel assemblies with fusion zones and/or heat-affected zones of high hardness (and correspondingly strength) are subject to cracking in H2S-containing water environments (a subcategory of environmentally-assisted cracking).

The test procedures are of interest to many industrial entities producing or installing gas and water pipeline networks and can be adapted relatively easily to their requirements.

Geographic information system synthetically collect the relevant geographic information of forest fire prevention such as terrain, water source, surface, roads, residents and building; and through the meteorological information system, we can timely control the weather information related to the forest fire ,such as the cloud, wind direction, humidity and temperature in the fire area now and in the future period; forest resource information mainly includes the information influent in fire, the fire load and forest resources value information comprised of forest types, surface fuel and forest resources value
Human resources information system is to collect the information related to human resources, mainly including: the command crew, professional team, emergency power, experts

The vastness Qinghai Lake, with its green water extending to the end of the sky, is like a huge emerald jade plate embedded between mountains and grasslands, constituting a magnificent scenery and beautiful scenery with a mountain, lake and grassland contrasting finely with each other.
More importantly, the scenic area should be conducted the ecological education and training for all staff in the scenic area, in addition to enable them to have the tourism professional knowledge and skills, as well as eco-knowledge.

The cooling solution uses water with a 25ºC temperature at entry point with a flow of 10 l/min.

Placing a logistics centre near combined transport terminals can provide long-term performance improvements for rail and water transport in the freight market.
The ten basic conditions necessary for the establishment of a logistics centre (LC) are identified as follows: (1) geographic location determines the LC as a link between commodity flows, (2) in terms of competition the LC must be the best, (3) trimodal transport links are a great advantage for a LC, (4) trimodal transport network ensures adequate commodity flows, (5) large enough space for the planned construction of the LC is a prerequisite for a reasonable price, (6) construction of an expertly conceived LC requires a development department which acts as a professional representative for all the business entities located in the LC, (7) enhanced competitive edge of the LC is gained even before opening if it is well connected to the public transport infrastructure, (8) Silicon Valley effect is accelerated by a concentration of logistics companies with a large number of employees, (9) degree of vertical and horizontal interdependence provides potential for synergies, (10) sufficient storage
