Surface ozone has been measured at Tranquabar (11°N, 79°9'E), a tropical rural site on the east coast of south India, during the years 1996 to 2004. The sunspot data were collected from Udaipur solar observatory during the same period. The relationship between annual mean smoothed sunspot number and annual mean surface ozone levels are studied by Pearson product moment correlation coefficient and that is found to be a high value 0.94. High positive rank correlation coefficients 0.76 and 0.62 obtained for the years 2000 and 2002 indicates the influence of higher solar activity over the surface ozone levels.Keywords

Mankind still struggles to bring the population food supply equation into balance. The lack of balance of the vital nutritive elements, especially, protein seems to be critical in developing countries. In India where protein malnutrition forms a major public health problem, about 30 per cent of the protein supplies are derived from vegetable sources. Vegetable proteins offer perhaps the only practical means of solving the problem of protein shortage in India for the present. Certain types of processing of legumes have been found to improve protein quality. Information in this line for legumes commonly consumed in India, is inadequate. Hence, this investigation was undertaken to evaluate the protein quality of sprouted, roasted and autoclaved Bengal gram (Cicer arietinum), green gram (Phaseolus aureus) and horse gram (Dolichos biflorus), which are the three commonly consumed legumes of South India.
- Dermatophilus congolensis Infection in Sheep and Goats in Delta Region of Tamil Nadu

Materials and Methods: A total of 20 scab samples collected from 18 goats and 2 sheep from Nagapattinam, Thanjavur, and Tiruvarur districts of Tamil Nadu. Smears were made from softened scab materials and stained by either Gram’s or Giemsa staining. Isolation was attempted on blood agar plates, and colonies were stained by Gram’s staining for morphological identification. Identification was also done by biochemical tests and confirmed by 16S rRNA polymerase chain reaction (PCR), followed by sequencing and phylogenetic analysis of the amplified product.
Results: The peculiar laddering arrangement of coccoid forms in stained smears prepared from scab materials revealed the presence of DC. Isolated colonies from scab materials of sheep and goats on bovine blood agar plate were small, hemolytic, rough, adherent, and bright orange-yellow in color, but some colonies were white to cream color. Gram-staining of cultured organisms revealed Gram-positive branching filaments with various disintegration stages of organisms. 16S rRNA PCR yielded 500 bp amplicon specific for DC. Sequence analysis of a sheep DC isolate showed 99-100% sequence homology with other DC isolates available in NCBI database, and phylogenetic tree showed a close cluster with DC isolates of Congo, Nigeria, and Angola of Africa. Genes for virulence factors such as serine protease and alkaline ceramidase could not be detected by PCR in any of the DC strains isolated of this study.
Conclusion: The presence of dermatophilosis in Tamil Nadu was established from this study.
