Shrinkage is defined as the reduction of volume caused by loss of water during the process of drying or firing.
Suthan from the School of Geological Sciences at the University of KwaZulu-Natal for his assistance in the recording of powder X-ray diffraction data.

The population of southern Algeria almost exclusively depend on the local groundwater for their drinking water and the available data indicate that fluoride levels often far exceed recommended limits, namely 0.6 to 0.8mg/l depending on the maximum day time temperature [7].
Precipitation and adsorption can be helpful in reduction of fluoride concentration in groundwater of the study area to appreciable extents.

Data report and analysis The cumulative CO2 emission was summed every day emission amount.
If N released from the decomposition of labile organic carbon could not meet the demand for plant growth, N fertilization will increase soil CO2 emission through enhancing plant biomass and rhizosphere respiration; in contrast, N fertilization will reduce soil CO2 emission if N mineralized from labile organic carbon could roughly meet the need of plant growth resulting in no marked reduction in biomass in the absence of N addition [6].

From the data available, in all cases sufficient amount of silver is found to be present, confirming the ability of the preparation method selected.
Therefore with increase in MO molecules for same number of active sites and irradiation time, there is a decrease in percent reduction rate.

According to the results of the thermal and dilatometric analyses, the solidus temperature of this alloy is 627°C, which is in good agreement with the data of [8].
The presence of Mg2Si particles after the compression tests leads to a decrease of the extent of solid solution alloying and a reduction of the strengthening effect during the aging.

Its depletion causes inhibition of cell growth with reduction of the synthesis of DNA, RNA and proteins in in vitro tests [4].
The sintered powders were characterized by X-ray diffraction, (XRD - Philips, XPert), data acquired in a range of 25-40o (2θ) using a curved crystal monochromator and CuKα radiation, operating at 45 kV and 45 mA, at a step size of 0.02o and 3 seconds per step.

The mean FQ reaction rate was calculated for 2000rpm and full load condition with intake temperature 306K and intake pressure 165kPa which did not appear knock phenomena according to experimental data.
Mean in-cylinder temperature diagram Pumping loss reduction As we all know, gasoline engine load was regulated by throttle.

The optimization was carried out by the use of an analytical sensitivity analysis and was verified using published experimental data.
For small variations of the parameters, a reduction of the iteration time occurs.

It is known that presence of atoms of chlorine and, especially, bromine effectively assists to the polymer combustibility reduction.
The analysis of copolycarbonate thermal stability data showed, that the chemical nature of bisphenol effects on the beginning of thermal decomposition of polymers in a lesser extent, and decay temperature is defined, generally by the thermal stability of ester group.

The critical current densities, Jc, of the bulks and thin films were estimated from data obtained with an Oxford Instruments 3001 vibrating sample magnetometer (VSM) using the Bean model.
We have shown earlier that the amount of inclusions of higher magnesium borides increases with increasing Ti addition [11] and that an increase of the synthesis temperature leads to a reduction of their size [5].
