Palandamizhar food systems reflect from ancient Tamil literature of Purananuru

Purananooru explains how mixed food systems are in the life of ancient Tamils, hospitality methods, dealing with guests, vegetarian and non-vegetarian diets, uses of food grains, and Tolkappiyar's evidence of feasting. This article deals with iguana meat, wild fowl- aral fish and mutton as non-vegetarian food. The use of Varaku rice as a staple food as a small grain food is explained

Low Complexity Multiplier-less Modified FRM Filter Bank using MPGBP Algorithm

The design of a low complexity multiplier-less narrow transition band filter bank for the channelizer of multi-standard software-defined radio (SDR) is investigated in this paper. To accomplish this, the modal filter and complementary filter in the upper and lower branches of the conventional Frequency Response Masking (FRM) architecture are replaced with two power-complementary and linear phase filter banks. Secondly, a new masking strategy is proposed to fully exploit the potential of the numerous spectra replicas produced by the interpolation of the modal filter, which was previously ignored in the existing FRM design. In this scheme, the two masking filters are appropriately modulated and alternately masked over the spectra replicas from 0 to 2$\pi$, to generate even and odd channels. This Alternate Masking Scheme (AMS) increases the potency of the Modified FRM (ModFRM) architecture for the design of a computationally efficient narrow transition band uniform filter bank (termed as ModFRM-FB). Finally, by combining the adjoining ModFRM-FB channels, Non-Uniform ModFRM-FB (NUModFRM-FB) for extracting different communication standards in the SDR channelizer is created. To reduce the total power consumption of the architecture, the coefficients of the proposed system are made multiplier-less using the Matching Pursuits Generalized Bit-Planes (MPGBP) algorithm. In this method, filter coefficients are successively approximated using a dictionary of vectors to give a sum-of-power-of-two (SOPOT) representation. In comparison to all other general optimization techniques, such as genetic algorithms, the suggested design method stands out for its ease of implementation, requiring no sophisticated optimization or exhaustive search schemes. Another notable feature of the suggested approach is that, in comparison to existing methods, the design time for approximation has been greatly reduced. To further bring down the complexity, adders are reused in recurrent SOPOT terms using the Common Sub-expression Elimination (CSE) technique without compromising the filter performance

Economic development in post-war Sri Lanka - management challenges and rewarding tasks

Sri Lankan economy would be improved to a great extent with the restoration of peace in the island and the rapid improvement in the tourism industry predicted by ADB lead economist Narhari Rao the Colombo stock market is also performing well, he said. The notable reduction in inflation from 20% to 2% followed by the Central Bank's decision to bring down interest rates, will contribute immensely towards economic development which is the right move. In the 70s, Sri Lanka was more developed than Malaysia and Singapore. Sri Lanka Should concentrate Education, Research development, Export manufactured goods, Health, Transports, Planned and implementation, Agriculture, foreign investment, Small medium scale industries, alternate energy, Construction and security. Singapore is an inspiration to Sri Lanka and other developing countries in terms of economic development, political stability, and good governance. In terms of fiscal and monetary policy, government expenditure to GDP ratio is about 10% with a budget surplus. The Central Bank of Sri Lanka's equivalent is the Monetary Authority of Singapore which is considered among the 10 most sophisticated financial markets. The money supply is endogenous (from within) and exchange rate policy curtails imported inflation. Singapore also has political stability and quality of governance is needed for the economy to grow. Singapore is managing a plural society, rule of law to maintain good governance. As a country with new born peace, Sri Lanka has key lessons to learn from Singapore. Sri Lanka is getting ready for the post war era in earnest. As the expenditure on the war begins to decline, the need to divert attention to development of the north and east ensues. Physically, politically and psychically rebuilding a country after nearly two generations of war is no easy feat Doing it in the middle of a global recession won't be swift or predictable. It will involve that noisily rabble called civil society

An Experimental Study on Mesh-and-Fiber Reinforced Cementitious Composites

Development of new composite materials which reduces the large consumption of natural resources is an approach towards sustainability. This study is an attempt to explore the possibility of adding polyolefin fibers (PL-F) in steel mesh reinforced cementitious composites (SMRCC) and conduct low velocity impact tests. For this purpose, test specimens of slab size 250 X 250 X 25 mm (thickness) were cast with steel mesh (3 to 5 layers) and polyolefin fibers (0.5-2.5% of  volume of specimens with 0.5% interval) and compared with control specimens (cast with steel mesh of 3 to 5 layers). Statistical t-tests were employed to find out the paired difference in impact energy absorption capacity between initial impact energy absorption (IIEA) and ultimate impact energy absorption (UIEA). Also, through statistical analysis, it was found that when steel mesh layers were varied keeping fiber percentage constant, and vice-versa, there were significant differences in the energy absorption capacity of cementitious slabs

BIOCHEMICAL CONSTITUENTS OF WITHANIA SOMNIFERA UNDER THE INDOLE-3-BUTYRIC ACID AND TRIAZOLE SOIL DRENCHING TECHNIQUES

The present study aimed at understanding the effect of indole-3-butyric acid (IBA) and triazole compounds viz., triadimefon (TDM) and propiconazole (PCZ) on the biochemicals of ashwagandha. Treatments were given on 50, 90 and 130 days after sowing (DAS). Biochemical constituents such as proline, glycine betaine and total alkaloids content were determined. It was observed that proline, glycine betaine and alkaloids content were enhanced by TDM and PCZ than followed by IBA treatment when compared to control for respective growth stages.  Among the treatments, triazole compounds caused pronounced effect to the biochemical accumulation in higher level when compared to IBA treatment. These results suggest that, triazole active compounds act as a growth regulator also influence hormonal balance and great significance, which is helpful to satisfy the needs of enhance the biochemical contents in Ashwagandha

Cage Farming of Cobia Rachycentron canadum

Cobia has gained popularity as a good candidate for mariculture due to its rapid growth and white meat of versatile use. It is considered as one of the most promising candidates for warm-water marine fish aquaculture in the world. Being the only member of the family Rachycentridae, it is found in the warm, temperate to tropical waters of the West and East Atlantic, throughout the Caribbean and in the Indo-Pacific off India, Australia and Japan. To date, research and development of cobia aquaculture has been initiated in over 23 countries and territories
