Moral Principles shown by Varadhar Nenjuvidu Thoothu

Literature is a mirror of the life of man. Due to the lack of time to read the classics in accordance with the change of time, many of the minor literature genres have been acquired. On that basis, famous kinds of minor literature such as Pillai Thamizh, Kovai, Bharani, Ula, Thoothu, etc., are featured. From that point of view, the researcher has chosen Varadhar Nenjuvidu Thoothu as his title in the Thoothu literature. This study is based on data on the period at which the minor literature originated, the interpretation of the word ‘Chitrilakiyam’, the significance of the word Chitrilakiyam, especially the semantics of the thoothu, the types of thoothu, the specialties of the Thoothu literature, and the moral principles in the Thoothu literature. This study is based on data on the principles of morality, the impermanence of worldly life, the degradation of human birth, the way to attain the benefit of birth, the destruction of sensuality, the dangers of human birth, the way in which the world can rise, the use of dasaavatharam, etc

Application of remote sensing in fisheries. In: Winter School on Impact of Climate Change on Indian Marine Fisheries held at CMFRI, Cochin 18.1.2008 to 7.2.2008

Satellite oceanic remote sensing is now playing a very important role in India for fishery forecasting, research and management by providing synoptic oceanic measurements. These can be used for evaluating environmental effects, which ultimately affects the abundance and availability of fish populations. Indian seas, which have a coastline of 8118 km, an EEZ area of 2.02 million sq. km and a shelf area of 0.53 million sq. km (Anon, 2002), have multi species composition. It is a well known fact that changes in ocean conditions greatly influence the natural fluctuations of fish stocks. Hence the information on variations in ocean conditions is necessary to understand the influence they cause on fish stocks and their distribution. This knowledge will immensely help in formulating the best fishery management strategies and developing efficient harvesting methods for fishery resources

Import substitution of combination wire rope. Part 2. Production and standardisation of 17 mm dia combination wire rope.

The prototype combination wire rope (Cift-CWR 1) developed for deep sea trawling was further studied for improvement, optimisation of efficiency and standardization. A series of improved prototype combination wire ropes (Cift-CWR 2 to 6) were twisted and evaluated their mechanical properties and reported in this paper with recommendations for a standard 17mm dia combination wire rope of 6S (7C+8+1 Scr) + 6 Crs(6+1+1 Crc) construction

Tensile strength properties of polyethylene netting twines under exposure to out-door and artificial UV radiation

Photodegradation of three types of polyethylene twines namely, polyethylene fibrillated tape twine, polyethylene flat tape twine and polyethylene monofilament twines were studied by exposing them to sunlight and artificial UV radiation. The percentage residual strength varied in the samples, the monofilament with the highest residual strength followed by fibrillated tape twine and flat tape twine. A plot of the difference between the breaking strengths of the fibrillated tape twine and the mono filament twines against any given period of exposure exhibited a linear relationshi

Import substitution of combination wire rope. Part 1. Design, production and evaluation of a prototype combination wire rope

Model combination wire ropes with different covering materials were prepared and worked out specification for the prototype. A table model hand operated wire rope twisting machine was also developed for this. Prototype combination wire rope was twisted in collaboration with M/s South India Wire Ropes Ltd., Alwaye. Specification details, properties and field performance of the prototype studied are reported

Development of lobster traps: preliminary experiments with three new designs of rectangular, Australian pot and ink-well traps

Result of experimental lobster fishing with three new designs, namely rectangular, Australian pot and ink-well traps at Muttam, Kadiapatnam, Colachal, Enayam and Vizhinjam, south-west coast of India during 1979-80 are reported. Preliminary studies show that Australian pot and rectangular traps as more efficient to the ink-well type

Spiny lobsters and their fishing techniques

Scores of publications on spiny lobsters and their fishing techniques are available from various parts of the world. A variety of fishing gears which vary in design and operation are employed for exploiting lobsters. A review of the work carried out on spiny lobsters with special reference to their distribution, fishing gear, fishing methods, baits and crafts in India, Sri Lanka, United States, Australia, South Africa, United Kingdom, Ireland and Portugal based on selected literature are considered and discussed

Paradigm of Mainstreaming Gender Perspective in Marine Fisheries Sector of India

Mobilization of Self Help Groups, setting up of Mahila Rural Cooperative banks, Women cell and collaboration and networking with NGOs etc are to be worked out by using the strategy developed in the case studies as a practical manual. Promoting “men and women partnership firms” instead of exclusively women-oriented enterprises is another practical strategy. It is seen that husband-wife enterprises with one or two helpers in fish processing/marketing in fishery related activities and other fishery related activity yields better prospects. Integration of the gender perspective in aquaculture research and technology development is an essential requisite because the gender mainstreaming approach advances gender equality and equity in the society. Similarly it is quite necessary for integrating gender perspective in aquaculture extension also because women are the important stakeholders of our aquaculture development process and our Extension system hardly targets the women folk for technological empowerment

Development of an efficient trap for lobster fishing

A modified trap was developed for fishing spiny lobsters. Experimental fishing was conducted using this trap along with traditional trap (as control) to assess the comparative efficiency. Design details and comparative efficiency of the modified trap is reported in this paper. From the analysis of variance, the difference in average catches between the modified trap and the control is found to be highly significant establishing the high efficiency of new trap

Efficiency of gamma irradiation and ethyl methane sulphonate in inducing variations in Jasminum auriculatum Vahl.

Vegetatively propagated crops like Jasminum auriculatum have a constraint in genetic variation due to a narrow genetic base that restricts the insights in any crop breeding programme. Mutation breeding is a potential tool that directs a way to create desirable variation effectively in vegetatively propagated crops. The optimum dose of mutagen is the one which produces the maximum frequency of mutation in turn the variation, with minimum killing. The aim of the present paper unveils the Lethal Dose (LD50) and the growth reduction dose (GR50) for both Gamma irradiation (GI) and Ethyl methane sulphonate (EMS) for the ecotype ‘Muthu Mullai’ of Jasminum auriculatum. These parameters of GR and EMS treated cuttings were analysed by considering the GR50 values of the mortality rate (57%, 48%), survival percentage (12.479Gy, 13.268mM), shoot length (18.59Gy, 18.28mM), root length (20.39Gy, 18.17mM), number of leaves (22.29Gy, 17.47mM), number of sprouts (22.97Gy, 16.17mM), vigour index (10.43Gy, 11.05mM), leaf length (21.61Gy, 19.90mM) and leaf width (19.2Gy, 16.17mM). The LD50 value was 12.479 Gy for GI and 13.268 mM for EMS treatment. The GR50 for different growth parameters ranged from 14.93 to 22.9 Gy for GI and 1.05 to 19.9 mM for EMS treatment. The mutagenic efficiency and effectiveness were 214.96 and 89.36 for GI and 48.66 and 33.77 for EMS treatment, respectively. These doses can be used for generating considerable variation, which can be put to use in future crop improvement programmes for Jasmine
