The Holy Quran （1982） is the Holy Book of the Moslems and the most understandable aspect of its eloquence. One of the most interesting aspects found in different languages is the use of implicatures or implied meaning. How and why such implicatures are generated and are discussed in pragmatics？ In this study, a list of conversations （direct and indirect） from ＂Surah Livestock＂（＂A1-An＇am＂）, the sixth Chapter of the Holy Quran, and the implicatures implied in the conversations are analyzed through a pragmatic theory： CP （Cooperative Principle）. The present study shows that in most cases, the non-observance of Grice＇s （1975） maxims is found in the maxim of Quantity and the least in Manner. Grice＇s CP and its contributory maxims have not been observed in the ＂Surah Livestock＂ in this study. All maxims of Grice have been flouted in This Surah （1982） and there is no difference among Gricean maxims as far as flouting in the Surah is concerned.

In this study, the effect of thermal oxidation on the lattice parameters of Ti-4Al-2V alloy was *** were oxidized at 450, 600 and 650 °C for 1-7 h in electric furnace under air atmosphere. The lattice parameters were determined using the Cohen method as a function of oxidation time at each temperature. The lattice parameters of as-received alloy are calculated as a = 0.29289 nm and c = 0.46652 nm. The thermal oxidation at 450 °C results in a gradual increase in a-parameter, whereas it goes through a maximum at higher temperatures（600 and 700 °C）. The results show that these maximums are reduced to an approximately constant value after a long-time oxidation. The c-parameter generally increases over the whole treatment condition. It is believed that these variations could be due to the dissolution of oxygen atoms in octahedral sites of hcp lattice of titanium.
