Awareness campaign for Fisherwomen

Women in fishing communities have decisioh-making role in community management. With the increasing commercialisation of fishing industry I women's access to post-harvest operations in fisheries has been declining: It is- estimated that only about 20 percent of women from traditional fishing households get opportunities for income generation from fishery related activities which are seasonal

Entrepreneur gains success in scientific prawn and crab culture

This enterpreneur makes lucrative earning from prawn seed collection too. A scientifically trained prawn-culture farmer may supply up to 0.1 million prawn seeds/day/seaso

Group farming for sustainable aquaculture

Sustainable farming is a critical issue in aquaculture development. The concept is well understood but the issue is that of methodology for implementing it. It is well recognized that fragmented holdings have been a major constraint in the implementation of farming practices by small-scale farmers. In India 80 per cent of the shrimp production comes from small and marginal holdings which follow different systems of production, including the traditional ‘pokkali’ farms of Kerala state, improved traditional farming, and scientific methods. Group farming, which was highly successful in paddy farming, was tested among small-scale shrimp farmers practicing paddy and shrimp farming in rotation in a cluster of ‘pokkali’ fields in Kerala. The model served as an effective extension intervention to educate farmers on sustainability while helping them to improve their farming practices. The farmers, including women, could be equipped with the technology for farming not only shrimp but also finfish, crab and aquaculture feed production by strengthening the farmer–extensionist–researcher–political–administrative linkages. The work was done during 1993–1996 at the Central Marine Fisheries Research Institute, Cochin, India. The study formed a part of the action research project on empowerment of rural communities through extension

Action research for rural empowerment in Chellanam fishing village

The empowerment approach aims at equipping the rural people with ways and means of improving their living conditions. Extension education was found to be useful in producing the desired change in the target grou

Note on the extension of prawn culture technology to women in a coastal village

Prawn farming is a potential area of income generation for women in fishing villages. Observations indicate that women in small scale prawn farming households do have involvement in the traditional system. They also play an important role in the management of other activities such as livestock rearing and vegetable cultivation in their farms. Given more information and training they can be usefully involved in the adoption of the technology and also management of the farms

Effect of doping on the dielectric properties of cerium oxide in the microwave and far-infrared frequency range

Cerium oxide (CeO2) has been prepared as a ceramic dielectric resonator by a conventional solid-state ceramic route. The sintered CeO2 has a high dielectric quality factor (Q×f), Q value of 10 000 at 6 GHz with a relative permittivity (ε′) of 23, and temperature coefficient of resonant frequency (τf of -53 ppm/°C. The Q value increases to 20 000 at 6 GHz when the CeO2 is doped with 1 mol% CaCO3. Higher levels of CaCO3 doping lowers the Q and ε′ values and simultaneously decreases τf. TiO2 doping decreases τf and slightly increases ε′, but deceases the Q value. The Q value of pure CeO2 increases to 105 000 at a frequency of 5.58 GHz when it is cooled to 30 K, whereas Q ≈ 85 000 at 5.48 GHz for 1-mol%-CaCO3-doped CeO2 at 30 K
