GREEN-HOUSES THAT YIELD SOLAR POWER TOO.

Scientists have developed 'smart' solar green-houses that can produce renewable electricity without reducing the growth of plants. The first crops of tomatoes and cucumbers grown inside electricity-generating solar green-houses were as healthy as those raised in conventional green-houses, researchers said. "We have demonstrated that 'smart green-houses' can capture solar energy for electricity without reducing plant growth, which is pretty exciting", said Michael Loik of the University of California Santa Cruz, United States. Electricity-generating solar green-house utilise Wavelength-Selective Photo-voltaic Systems (WSPVs), a novel technology that generates electricity more efficiently and at a lower cost than traditional photo-voltaic systems. These green-houses are outfitted with transparent roof panels embedded with a bright magenta luminescent dye that absorbs light and transfers energy to narrow photo-voltaic strips, where electricity is produced.
WSPVs absorb some of the blue and green wave-lengths of light but let the rest through, allowing the plants to grow.

VIEWS OF MANU AND KAUTILYA ON THE ADMINISTRATION OF JUSTICE.

The state performed its duty of protection of society and the individual through coercive enforcement of the standards of justice based on the concept of ' Dharma '. From the Vedic period onward, the perennial attitude of Indian culture had been justice and righteousness. Justice, in the Indian context, was a human expression of a wider universal principle of nature and if men were entirely true to nature, their actions would be spontaneously just. Men experienced Justice, in the sense of a distributive equity, as moral justice, social justice, and legal justice. Each of these forms of justice was viewed as a particularisation of the general principle of the universe seen as a total organism. Impartial administration of justice was always regarded as one of the main duties of the King and he was considered to be the fountain of justice. The ethical code of society and its cultural standards were inter-related. The cultural maturity and social amicability and even their det...

ARCHAEOLOGISTS DISCOVER TOMBS IN EGYPT DATING BACK 2,000 YEARS.

Egypt's antiquities ministry said on 14th August, 2017 (Tuesday) that archaeologists have discovered three tombs dating more than 2,000 years, from the Ptolemaic Period. The discovery was made in the Nile valley province of Minya south of Cairo, in an area known as al-kamin al-Sahrawi. The unearthed sarcophagi and clay fragments suggest that the area was a large necropolis from sometime between the 27th Dynasty and the Greco-Roman period. ----------------------------------------------------------------

ANCIENT INDIA'S LINKS TO TODAY.

You may not have heard of Shu-ilishu but he is a man of great significance. He reaches out to us from almost 4,300 years ago, through a small Akkadian cylinder seal now housed at the Louvre Museum in Paris. On the seal, you will find an image of him talking to two men. The inscription describes Shu-ilishu as the interpreter of the Meluhhan language. 'Meluha' was, in all probability, the term used by ancient Mesopotamians for the Indus Valley region, and the presence of an oficial 'interpreter' there indicates just how important the steady flow of good from the Indian sub-continent was.  Precious and vibrant lapis lazuli stones, carnelian beads, wood and even dogs would go across via old trade routes and ports like Lothal (in modern-day Gujarat) to Akkad, capital of the Akkadian Empire (03rd millennium BCE) and now in modern-day Iraq. There are also references to a settlement of Meluhhans in the city of Guabba in Sumer, in Mesopotamia.  The story of Shi-ilishu and ...
