Results showed no significant differences for indoor air temperatures reduction among the insulation materials.
The internal gain of the building was due to: § Number of people: 2 § Max. sensible gain: 90 W per person (90 W x 2 person = 180 W) § Max. latent gain: 60 W per person (60 W x 2 person = 120 W) The simulations were performed using the nearest climatic data (Kuala Lumpur/Subang, Malaysia).
The temperatures reached the lowest peak of the daily average data at 0645h to 0715h at the temperatures between 23.2 and 24.7 °C.
Although a significant reduction in the hatchery indoor temperature was achieved with the installation of insulation, the reduction was still far from the acceptable upper thermal limit (34 °C) by human in tropical regions [18].
Temperature reduction in attic and ceiling via insulation of several passive roof designs.

A 1-D model of a turbocharged 1.0L 3-cylinder gasoline engine was developed using simple model described in Figure 1 and validated with actual engine test data as reported by King et al. [19].
Results and Discussions A 1-D model of a turbocharged 1.0L 3-cylinder gasoline engine was developed using simple model shown in Figure 1 and validated with actual engine test data.
Although the results follows the same trend as that of the engine test data at higher rpm, at low engine rpm it was far lagging behind the test data.
The highest BSFC normalised data reduction can be shown at 2000 rpm with 2.19%.
The peak improvement of BMEP can be shown at 1500 rpm, but at lower engine speed (ie <2500 rpm) the turbo compounding have a similar impact on the normalised BMEP data with range of improvement from 1.3 to 2.5%.

The buyers purchase the emission reduction quota distributed by the emissions
trading scheme under the "cap and trade" system.
It is the first and only voluntary greenhouse gas emission reduction transactions, as well as legally binding emission reduction commitment to the organization and the market pioneer trading platform in North America, and the first emissions registration, reduction and trading system which includes all six kinds of greenhouse gas on the globe.
The process of transactions and data from the internal system records, but not made public.
Members exceeded emission reduction targets can be stored.
Relevant data shows that China's current annual emissions of greenhouse gases over 10% of the global total, ranking second after the United States in the world.

The degree of concentration is usually expressed as the volume reduction factor in ultra-filtration processes.
A mathematical model was developed using MATLAB 7.8 software to calculate the optimal volume reduction factor.
A trend line expressing the relationship between volume reduction factor and production cost can be fitted with MATLAB 7.8.
The benefits in energy-saving and discharge reduction for every ton of APMP pulp produced using this new concentration process under its optimal conditions and volume reduction factor can be calculated based on the data in Table 6.
The optimal volume reduction factor calculated was 0.93.

It provides a basis for noise reduction method
In addition, no-load maximum speed loader engine and cab vibration frequency spectrogram showed that the most important frequency components do not consist of 120Hz and 216Hz, so we learned that the vibration of the engine and the cab is not the main sound source outside the cab and engine. 4.4 Interior noise frequency spectrum chart analysis By interior cab noise measurements, we recorded noise data on the left and right ears of the driver, two following spectrogram are achieved.
Then help to determine the reduction method and improve the efficiency of the reduction method by match the main frequency.

The difference between data obtained using the experimental model and the data obtained by computer analysis is less than 5%.
Computer modeling data: rotation angles and angular velocity Experiments The prototype model for experimental studies is shown in Fig. 4.
Smoothing [6] is applied to obtain acceptable accelerometer output data (Fig. 5).
Therefore, it is possible to increase the driving link rotation angle from 180° to 240°to obtain correct data.

The oxidation process
of chalcopyrite does not produce covellite, Bornite is not the intermediary species formed during
the chalcopyrite reduction.
The product of this reduction is chalcocite(Arce,2002).
The analysis of CV associated with SEM and EDAX data can provide information about physical, chemical and biochemical processes occurring at the electrode/electrolyte (sulphide/culture medium) interface in the presence and absence of Acidithiobacillus ferrooxidans and Acidithiobacillus caldus.
peak b, reduction reaction could be infered according to following equations(Holliday, Richmond,1990): 2+ 0 Cu +S +2e CuS→ (11) 2+ - 0 Cu +2e Cu→ (12) Fe 3++e Fe 2+ (13) Peak c(E=-0.2751) , there maybe exist the following reaction: + - 2+ 2 2 1.60 3CuS+2H +3.2e +0.6Cu Cu S+H S+ Cu S → (14) Jang reported that chalcopyrite can be hydrothermally converted to copper sulfides, covellite(CuS) and digenite(Cu1.8S), Bevilaqua studied bornite residues from bacterial leaching using X-ray diffraction indicated the formation of a new mineral phase identified as CuS (covellite)( Bevilaqua,2009).
SEM and EDAX data also demonstrated the satisfactory result.
