This paper proposes capabilities of transparent glass window design with energy-saving and heat insulation for carbon reduction issues.
A reduction of indoor temperature around 1℃~3℃ is able to reduce the usage of air conditioning in summer time and bring with issue of the significant environmental protection benefit.
However, the goal of this paper is especially for the energy-saving and heat insulation glass and then it can significantly reduce fuel consumption in heating due to a reduction in heat loss, and thereby lowering harmful gas emissions.
Data from manufactures indicate that the refractive index of transparent acrylic (Polymethyl methacrylate or PMMA) is 1.49, and the surface refractive index R% can be calculated as roughly 4%.

The reduction and the omission of phosphate in both media did not significantly influence the culture parameters including the yield of biomass.
Reduction in the metal concentration was observed in the rotary shake flasks after 15 days of incubation.
The acidic conditions in stationary cultures were constantly maintained even up to 60 days of incubation with a gradual reduction in media pH.
A gradual reduction in the concentration of Ce and Th was observed in the leach liquor of rotary cultures after 15 days of bioleaching and was attributed to biosorption of metals by mycelium [11, 12].
Bioleaching of monazite may be due to organic acid production, siderophore production (data not shown) or other metabolic products.

A very important one is the protection of personal data, which is defined differently in different countries.
Vessels equipped with AIS transponders send static, dynamic and voyage related information data.
The data is transferred in regular intervals, and other vessels can automatically locate AIS equipped ships.
A safety concern, as with RIS, was the usage of private data.

The reduction of the particle size is very important to get better properties of the hard metal.
The reduction of the coercitive field with milling time increase can be related with the reduction of free cobalt in composite.
The reduction of density can be related with the appearance of the non magnetic phases and reduction the hardness is related the reduction of density.
The hardness increase with the reduction of the particle size (pores reduction), this also originates an increase in the coercitive field.

Tool wear details are given based on resulting cutter diameter and slot width reduction.
The rate of tool diameter reduction was significant in the first ~500mm machined but which then stabilised for the remainder of the trial.
Also visible is fracture behind the cutting edge corner leading to reduction of the tool diameter by 16.4% (up to 82μm) after 520mm cut length.
Based on this, the reduction in tool diameter (inferred from slot width data) was used as a means of assessing tool wear progression, as suggested in several publications [3, 11].
The data relates to forces after cutting 520mm slot length.

There was a reduction in the unburnt hydrocarbons (THC) and carbon monoxide (CO) emissions by 15% and 89% respectively, but the NOx emissions increased by 78%.
HC emissions were found to decrease linearly with increasing N2 dilution and for a given quantity of fuel, the emissions reduction was at a constant amount.
Table 1: Engine specifications Displacement volume 399.25 cm3 Cylinder Bore 76 mm Cylinder Stroke 88 mm Compression Ratio 14:1 Exhaust Valve Closed 350o BTDC Exhaust Valve Open 225o BTDC Inlet Valve Open 12o BTDC Inlet Valve Closed 132o BTDC Dynamometer Direct Current with maximum reading is 50 Nm The operation of the engine used for the experimental work was managed and controlled by a PC-based data acquisition and control system.
For the exhaust emissions there were significant reductions in the emissions of CO and THC while NOx was on the increase at about 20% CO2 proportion in the mixture.
These findings, if implemented, will assist sustainable developments in the country through reductions in the consumption of crude oil.

The models are compared with the experimental data collected from ultrasonic bone cutting experiments.
Although the proposed cutting mechanism is supported by the data, the blade gain is insufficient to enable through cutting of long bone or other difficult to cut materials.
The bone specimens were assumed to be isotropic and the mechanical properties were determined from experiments and previously published data [7].
Using an average of the experimental data allows a single K1C value to be adopted for FE simulations but with the consequence that the results can only be described as typical of bone and cannot be directly compared with a particular set of measured data.
Fig. 2 (a) FE model of CT specimen; (b) Experimental and FE data of ultrasonic cutting amplitude for CT specimens under different static loads Although the blade initiated a crack in the specimens for all the experiments, the data with no applied static load, P, were achieved experimentally by using the blade at the limit of its amplitude capability.

It proposed controllable preparation of this type thin film by chemical solution deposition and co-reduction, and study on the crystal orientation and regulation of the band gap gradient.
It intends to prepare Cu-AⅢ-BⅥ2 compound crystalline films using chemical solution deposition and co-reduction method.
Study on the structures and photoelectric properties of copper-based chalcogenide crystal thin films: (1) In the aspect of material structures, it mainly includes phases, lattice constants and defect, thickness of crystalline films, binding between film and substrate, surface morphology and interface structures of multilayer films etc.; (2) In the aspect of optical properties, by the transmission spectrum and reflection spectrum analysis and data processing, it will obtain the absorption intensity of light and to calculate the band gap of the crystalline thin films; (3) In the aspect of electrical performance, it need to measure the variable-temperature Hall coefficients and conductivity types, carrier concentration and mobility, the resistivity of crystalline thin film samples; By making product film samples into battery devices, the I-V curve, short-circuit current (Jsc), open circuit voltage (Voc), fill factor (FF) and conversion efficiency (η) and other properties of the battery

There was no other peak in the diffraction data that had been observed.
This process leads to a change in the intensity of specific peaks in the X-ray diffraction test data.
The hematite phase cannot be detected from the diffraction data of the test results because hematitis is likely to have an amorphous form [20].
Based on the data, a significant reduction in crystallite size is observed from the initial ilmenite mineral sample and ILMW10 until ILMW70, namely 410 to 123 until 28 nm.
Therefore, relevant comparative data cannot be obtained.

In this study we report quantitative data on such effects for mono and multi-crystalline Si materials with different amounts of crystal defects in the wafer bulk and different levels of boron concentration, and we discuss PDG versus other sites of potentially competing mechanisms of metal gettering.
ICP-MS data do not provide direct information regarding the chemical state of metal impurities in the silicon.
However, less reduction of total Fe is detected for high concentration of boron in the CZ silicon.
Raising the temperature to 950 °C and higher probably leads to complete disappearance of interactive forces between Fe + and B , as we can conclude from our PDG data on heavily B doped silicon.
