Life values in Porunmozhik Kanji of Puranaanuru
Tamil philosophies have set high standards for the internal and social lives of people. These are provided with a view to fostering individual relationships and social welfare. Purananuru, which is one of the anthologies of the Sangam, talks about war, the country's specialness, the fame of kings, politics, education, etc. It prescribes many values of life which are necessary for individuals and kings. Puranaanuru insists on these as individual virtues and social virtues. The songs featured in Puranaanuru are grouped into landscapes and disciplines. Among these, the discipline called Porunmozhik Kanchi is meant to highlight the positive things that are beneficial to life. Seventeen songs are composed in Purunmozhik Kanji in Puranaanuru. Considering these songs as basic data, this article highlights the values of life that they express. Basic values such as not doing non-beneficial things, helping, compassion for life, effort, friendship, charity, diligence, the duty of kings, universal love and respect for others are featured in these songs. These values, which are included in Puranaanuru, provide a fair and impartial life for the human race. These are long-lasting. These are common to all people, irrespective of country, race, and language. Such values are described in this article with appropriate evidence of the style embodied in the porunmozhik kanji songs. These values have been indicated for approval with the comments from Thirukkural. This article highlights the persuasion of these songs about the social duties that the king and the citizens have to perform
BIOREMEDIATION OF COPPER (II) FROM AQUEOUS SOLUTION USING TAMARIND KERNEL POWDER
Heavy metal pollution is nowadays one of the most important environmental concerns. Anthropogenic activities like metalliferous mining and smelting, agriculture, waste disposal or industry discharge a variety of metals such as Ag, As, Au, Cd, Co, Cr, Cu, Hg, Ni, Pb, Pd, Pt, Rd, Sn, Th, U and Zn, which can produce harmful effects on human health when they are taken up in amounts that cannot be processed by the organism. Physical and chemical methods have been proposed for the removal of these pollutants. Conventional methods to remediate heavy metals contaminated site are excavation and solidification/ stabilization, these technologies are suitable to control contamination but not permanently remove heavy metals. Nevertheless, they have some disadvantages, among them cost-effectiveness limitations, generation of hazardous by-products or inefficiency. Biological methods solve these drawbacks since they are easy to operate, do not produce secondary pollution. Heavy metals having relatively high density are toxic at low concentration. Microorganisms and plant are usually used for the removal of heavy metals. Bioremediation
is increasingly considered for clean-up of metal contaminated and polluted ecosystem. All the metals are toxic, but some of these are useful in low concentration. These large verity of heavy metals cause serious water pollutio

An Analysis of Humanimalia in Octavia Butler’s Clay’s Ark
Octavia Estelle Butler can be considered a visionary writer from many perspectives. The prominent science and speculative fiction writer is known for her afrofuturistic tropes. Her novels reflect relevance in today’s scenario in myriad ways. Clay’s Ark (1984) is a part of the Patternist Series. In this novel, Butler envisioned a humanity plagued by an alien microbe from another star named Proxima Centauri. The novel traces the spread of the pandemic caused by the Clay’s Ark microbe resulting in hybrid children who mix human and animal characteristics. Butler chose the trope of the alien microbe in a very different yet believable way. The hybrid children are the next stage of evolution in Butler’s Patternists world. The aim of this paper is to explore the hybrid identities caused by the pandemic in Octavia Butler’s Clay’s Ark through the lens of biopolitics of difference and to reflect on the metaphorical significance of the same
