We seem to encounter systemic problems of corruption, moral bankruptcy, and spiritual decay. This leads to a rise in violence at various levels： individual, familial, societal, global, environmental, and biological. In order to combat these problems, it is necessary to examine the diverse semantics of the concept of peace： positive peace, negative peace, world peace, socio-cultural peace, and individual peace. The semantics of peace changes according to the context, for example, ＂May he rest in peace,＂ is quite different from： ＂His beautiful memories will give you peace.＂ Since society is constituted of a group of persons, an individual becomes society＇s substantive foundation with his/her conscious self, made of mind, body and spirit. The individual with creative power can become an agent of positive change. Using the interdisciplinary socio-linguistic/semantic and humanistic-philosophical approaches, this paper analyzes the ＂all-inclusive＂ and ＂interdependent＂ nature of life and the role and power of the individual （self） in the creation of peace at diverse levels： personal, community, the globe, and the cosmos. The paper draws heavily from India＇s spiritual worldview and humanistic techniques in resolving conflicts and attaining freedom from ill-health for peaceful living.展开更多
The family of Cr（Ⅲ） and Fe（Ⅲ）-doped rutile pigments of nominal composition （M^ⅢM^V）xTi1-2xO2, with M^Ⅲ = Cr（Ⅲ） or Fe（Ⅲ） and M＇（V） = Sb, Nb, Ta, with x = 0.03, 0.15 and 0.25 were investigated as cera...The family of Cr（Ⅲ） and Fe（Ⅲ）-doped rutile pigments of nominal composition （M^ⅢM^V）xTi1-2xO2, with M^Ⅲ = Cr（Ⅲ） or Fe（Ⅲ） and M＇（V） = Sb, Nb, Ta, with x = 0.03, 0.15 and 0.25 were investigated as ceramic pigments covering the yellow-ochre-brown palette. The formulations containing Fe（Ⅲ） are novel compositions not included in the commercial rutile pigments. The materials were characterized by XRD （X-ray diffraction） analysis and FTIR （Fourier transformed infrared spectroscopy）. The transition temperature from anatase-to-rutile was estimated by the evolution of the spectral patterns. This crystal phase transition is responsible of the color formation. A higher distortion of TiO6 octahedra is observed in the case of （FeSb） containing cells which contribute to the enhancement of the light absorption. The coloring performance of all the formulations were evaluated by enameling the mixtures containing 5% pigments and commercial frits representative of single and double firing industrial processes. The chromatic values obtained are in the yellow to brown domain of the chromatic plot, depending on the composition of the pigment-frit batch. In the case of the Fe-glazes, and particularly the combination （FeNb）, the chromatic values are close to the best yellow tinting. This new FeNb-rutile pigment could be a more benign substitute of Cr-yellow pigments. The homogeneity of the enamels was confirmed by SEM （scanning electron microscopy）-EDAX （energy dispersive X-ray analysis） microscopy.展开更多
