P-chlorobenzoic acid (p-CBA) reduction rate can be greatly reduced in TiO2/UV and TiO2/VUV processes [2].
The photo- degradation with LPM lamps which emit UV radiation at 254 nm can be applied in reduction of natural organic matter in water [3].
More UV radiation in limited volume benefits cost reduction and compactness of systems.
Stability and repeatability of data can be ensured when the lamp was operated for 15-20 min after the change of discharge condition. 4.

Introduction Statistical data on Taiwan indicates that the ratio of new buildings during the period 1990 to 2008 reduced to 3% of total constructions while the ratio of existing buildings reached 97%.
However, studies demonstrate that current legislative efforts are insufficient to reach national environmental or carbon reduction targets [2,3].
If lighting system consumes 35% of the total energy consumption of a building, the adoption of efficient lighting systems such as T5 and LED indicator lights should reduce energy consumption and costs of a building by 10-17.5%, enough to reach the environmental or carbon reduction targets of the Taiwanese government.
Fig.3 Comparison of payback period between GBRP investment and normal purchase investment Summary The study estimates that replacing old T8 fluorescent lamps with T5 fluorescent lamps and LED indicator lights can achieve a 10-17.5% reduction in energy consumption of existing building, but the economic benefits are difficult to estimate accurately.

The values of the maximum loads were from 4.5kN to 2.7kN that were based on the data from lap-shear tests.
As shown in Table 2, the increase in the amounts of pre-straining led to the increase in the tensile strength and the reduction in the elongation.
The figure shows that a good joint was obtained indicating that the reduction in the ductility of the pre-strained NG5754 alloy sheet was within acceptable limits.
In addition, the greatest amount of reduction in the fretting area also occurred from 0% to 3% pre-straining, as shown in Fig.6.

(°C) 220 L 3 0,015 10 0.0045 1140 15 L 3 0,015 0,7 0.06 1350 The decrease in CO partial pressure results in a reduction in nitridation temperature of about 200°C.
There is a little gap between the data from GEMINI 2 and the calculated values (Table 1).
In this case, carbothermal reduction of Al2O3 occurs above 1800°C, so no oxicarbides or carbonitrides can be formed.
Jung: Is it possible to synthesize cubic aluminum nitride by the carbothermal reduction and nitridation method?

Biodiesel is recognized as a potential fuel with many beneficials effects, especially in emission reduction.
The boiler was operated in full load mode during the test, while data was collected in every 10 minutes.
At higher blends of biodiesel (B50), more combustion air show elevated levels of CO and a reduction of CO2.
In the use of higher blends of biodiesel, when the air intake to the combustion chamber is beyond the optimum amount of excess air, it caused a reduction in exhaust gas temperature.

Based on experimental investigations, Gürü et al. [2] concluded that manganese, as a fuel additive, has a greater effect in the reduction of the freezing point of the fuel, than copper, magnesium, or calcium.
The effect of cerium on the size distribution and composition of diesel particulate matter has been studied by Skillas et al. [7], indicating a reduction in the accumulation mode, but an increase in ultrafines.
The experimental data have to be analyzed to determine brake power, brake mean effective pressure, specific fuel consumption and brake thermal efficiency.

The initial Al sheets were then asymmetrically rolled to different reductions ranging from 0 to 90% on a laboratory asymmetrical rolling mill with roll radius ratio of 1.5.
Total 5 passes were performed, with reduction of more than 50% in thickness after each pass.
The average r-value (r _ -value), and Δr-value were obtained from the measured data.
After asymmetric rolling with 90% reduction in thickness, one-tenth surface layer (S=0.9) showed rotated cube texture component, {001}<110>, S texture component, {123}<634> and weak gamma-fiber texture component, ND//<111> and center layer (S=0) showed rotated cube texture component, {001}<110> and weak gamma-fiber texture component, ND//<111> in Fig.2 (b).

Of the thirteen changes, twelve resulted in cost reduction, eight in quality improvements, and five in extension of production capabilities [7].
It is not surprising that total quality management (TQM) has become a source of ideas for pollution reduction that can create offsetting benefits.
Even the local toxicologist had been given no data about how lethal was the escaping gas.
Sony has set forth the Sony Group Environmental Vision, the goal of which is a "zero environmental footprint," that is, reduction of the environmental footprint of their corporate activities and of every Sony product throughout its life cycle to zero, and they continue to pursue a wide range of related initiatives.

The TWC advantage is related to a simultaneous implementation of the CO oxidation, hydrocarbon oxidation and NOx reduction reactions [1].
However, despite the high activity in CO and hydrocarbon oxidation, palladium has limited activity in reduction of nitrogen oxides [1].
Rhodium is another necessary TWC constituent and is widely recognized as the most efficient catalyst for NOx reduction to N2.
According to XRD analysis data (Fig. 2), the samples treated at 1000 and 1100 °C are characterized with quite similar diffraction patterns.
