The microwave system consists of modified multimode domestic microwave (1 kW, 2500 MHz), fluidized bed glass quartz reactor (5 cm internal dia. x 20 cm height) with wire mesh which serves as screen support as well as distributor plate, N2 and CO2 gases, K-type thermocouple (0 – 1200 oC range) inserted into the bed region and data acquisition system linked to personal computer for continuous monitoring and recording of process temperature.
Reduction in radiation time is expected to bring about considerable reduction in cost of production as well as improvement in the pore structure.

This can be explained by a lower cracking reaction rate of the more complex hydrocarbons contained in the camelina oil, causing a reduction in the CO residence time, and hence a smaller time interval for its further oxydation into CO2.
However, the experiments also show that camelina oil may be used, with certain penalties, as fuel, allowing for a significant reduction in the consumption of pure kerosene, which is more expensive, and also not renewable, or eco-friendly.
A series of tests at different engine speeds is scheduled for the near future, but such data is unavailable at this moment for publishing.

Recently, for optical backbone networks, mixed line rate (MLR) networks have been explored to support different rates on different channels on the same fibers to achieve cost efficiency in an optical network, and to exploit the volume discount [3] of 40 Gb/s and 100 Gb/s transponder, in the networks In an optical network [4], the failure of even a single lightpath can lead to huge data loss.
As the traffic grows, the cost reduction of MLR networks in comparison to SLR networks becomes significant.
However, the flexibility offered by the MCR approach for MLR networks, in comparison to the FCR approach, does not provide a significant cost reduction.

heat dissipating area; Using standardized module and prefabricated unit, reduce demand for material, reduce the costs of construction and operation, cut down the construction waste and pollution; In terms of building structure, the large-scale use of recyclable steel as main structure of building; Maximize the area of south-facing glasses, minimize that of the north-facing glasses (figure 2), and to control the proportion of the total windows and walls than 0.3 or so, the south-facing wall has large area of windows which can be opened (the area is larger than 30% of the total window area) ;the southeast and southwest external wall use shading devices, the use of light reflection plate will reflect sunlight into the main office space, the upper with skylights to enhance natural lighting (figure 3), to reduce energy consumption, uses the excellent thermal performance of building palisade structure, such as low-e glass, high-performance exterior insulation materials, low thermal incremental reduction
To make the buildings realize the goal of reducing carbon emissions and save energy, it’s not comprehensive that only from the application and design of the passive and active low carbon energy saving technology, because it must cooperate with the relative corresponding evaluation standard, evaluate the building from the design stage to the operation and even the whole life cycle assessment of demolition in the future to obtain data on quantitative, this will be the important stuff to evaluate the building whether receive prospective goal of carbon emissions standards and energy conservation.
Based on life cycle assessment of building carbon reduction countermeasures study [D].

According to data processing on this basis, the diffusion coefficient of SCM435 steel increases as temperature increases at 900-1100℃.
Therefore, the reduction of the number of grain boundary results in the reduction of the diffusion coefficient.

AM employs additive processes (may be combined with subtractive machining in future) to deliver finished goods from digital data; thereby eliminating all tooling requirement [2].
AM enables a creative design process with the advantage of faster product development time and consequential reduction in tooling cost.
AM offers increasing benefits in production schedules and flexibility for manufacturing operations due to reduction in tooling costs and design requirement [3].

The reduction of surface tension made sands can be well coated with modified sodium silicate, and the adhesive fill with the sand void.
The thermal expansion and shrinkage of [SiO4] are also different from [PO4], the thermal expansion coefficient(α) of the vitreous formed by sodium silicate is 13.46×10 -7/℃, that of ZY is 89×10-7/°C [10,11], due to a great difference, interpenetration network structure formed in hardening process can easily break under calcination of high-temperature and cooling, and the adhesive film coated on the sand surface was damaged, leading to the great reduction of the residual strength of high temperature and improvement of collapsibility of molding sand.

Introduction According to the related statistics data, expected by 2030, fossil energy including oil, natural gas and coal still occupies the mainstream energy status in the world.
That’s China's strategy development direction according to optimize energy structure, fulfill commitment on carbon emission reduction and actively respond to climate change.
In order to change this situation, development and utilization of coal resources must be based on the core of circular economy, promoting clean coal production, circulation efficiency and energy-saving emission reduction, the exploitation and utilization of the demand for natural resources and ecological environment will reduce to the lowest degree with minimal resource consumption.

All data shown in this paper was measured at 5 K with the proton current at MLF of 100 kW or 200 kW.
Such a large reduction of moment size by only 10% hole-doping is hard to explain [1].
Possible explanation for the large reduction of intensity is that additional intensity exists in the much higher energy region, and/or that the broadly distributed intensity in the momentum space makes the evaluation of real magnetic signal with separating from the background difficult, leading the underestimation of the intensity.
