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.

It can be noted that the reduction of excess pore pressures increases with the growth of the dynamic stress ratio to static stress ratio ηd/ηs.
The reduction in excess pore pressures increases with the growth of the dynamic stress ratio.
Furthermore, the reduction of excess pore pressures increases with the growth of cyclic stress ratios.

Opposite to other authors, we consider the stiffness reduction at the location where the bending moment is maximum, afterwards weighting it for damages placed on other locations with the influence of energy stored in that location.
In all cases Eq. 1 accurate predict the frequency of the damaged beam by considering the effect of stiffness reduction calculated with Eq. 5 and using the deflection values from Table 1.
Additionally, our relation is valid for any cross-section shape, proved using data from Table 1, extending the availability of the frequency-based damage detection methods to beams with any cross-section shape and even made by composites.
Graphical representation for function γ(a/h) proposed by different authors Conclusions This paper introduces a mathematical relation who expresses the stiffness reduction in respect to damage depth, applicable to any beam structure.

In previous research work it was identified that phytoremediation evolves several positive effects onto the soil and groundwater of the contaminated site by stabilization of the soil cover and sequestration of heavy metals/ radionuclides (MM/R) and metalloids in the root zone, reduction of the seepage water formation (up to 65%) and minimization of the groundwater contamination with HM/R and metalloids by ≥ 90% [5].
In general, the addition of compost and sand as soil improvements demonstrated a positive result for the plant growth, which was in accordance with literature data.
The growth of the plants in combination with the soil amendments makes a high contribution to the reduction of seepage water formation (up to 65%) as well as to the reduction of the contaminant load of the leachate (≥ 90 % decrease) [5].

Diagnosis may also be performed in a case when a reduction in the load capacity of a structure, caused by inappropriate maintenance or preventive works during the use of the structure, occurs.
Figure 1: Kučera’s drilling machine with an adapter and the original drill bits: a) prototype of components for assembly of reduction from 3D printer, b) flat drill bit mounted in the chuck, c) flat drill for wood, d) components for assembly of reduction, e) drills Kučera`s drill, which are used for mortar diagnostics (original) The overall modification of the Kučera’s drilling machine was based on the requirements of the attachment of a wood drill bit.
The calibration relationship for determining the strength based on the depth of a hole, which is not yet in the common practice, can then be found based on this data.
