We have explored the potentia1 of using magnetic susceptibility( χif) as a proxy for past rainfall variations in a tropical region, and also the potentia1 of tank-bed sediments from Southern India as a paleoarchive The 3,700-year rock magnetic record from Thimmannanayakanakere (14°12 N, 76°24 E), a smaH tank near Chitradurga town, Karnataka, exhibits considerable fluctudtions in χif Discountlng the possibilitestres of magnetite from biogenic and anthropogenic sources and of dissolutio of magnetic minerals, the χif signal must be related principally to rainfall in the tank-catchment There is a good correlation of χif with instrumental rainfall data (r = 0 65 for Peninsular India, r = 0 45 for Chitradurga Stationa)n d histoncally recorded rainfall events Presuming that χif variations are produced mainly by rainfall variations and that there was no signtficant human impact in the catchment and no slumping or bioturbatio of sediments we have reconstructed the paleorainfall profile for thc last 3,700 years for Chitradurga region The profile is chronologically constrained by two I4c dates Several events of drought and high rainfall, and onset of aridity are corretatable with similar events documented in speleothems from chfferent parts of india, a tree-ring from western India and lake sediments from Rajasthan We have thus shown that χif 1s a proxy for rainfall in tropical regions and that tank-bed sediments from tropical lndia are an important archive of paleorainfall/paleoclimate data.Keywords

Background: In the field of forensic sciences, Practitioners face major problems in personal identification of humans. Lip prints and finger prints can serve as a significant tool for such identification and gender determination as they are unique and distinguishable to each individual. Aim: This study was aimed to evaluate the comparison of lip print and finger print pattern in Salem population for sex determination. Methods: This study comprises 200 lip prints (100 females and 100 males) which were randomly selected among Salem population with age ranging from 15 to 30 years and were collected with lip stick with the help of a cellophane tape on a white sheet, the same people were asked to press the cleaned fingers of right hand over ink-stained pad and the impression of inked finger was then transferred to the same white paper. Lip prints and Finger prints were examined with magnifying hand lens for pattern distribution - classified, recorded and analyzed. Results: Our study proved that the prevalent lip print in the males and females were Type III and type I respectively. The most prevalent finger print in the male was whorls Type and in female it was Loop type. There is statistically significant association between of these two parameters (p value=0.001) and thus these combinations can be implicated in detection of individuals. Conclusion: The use of lip and finger print patterns has been suggested to be consistent and reliable to suspect a fault. Correlation of these two parameters has significant association and thus the result of the present study can provide an additional tool in forensic science for gender determination.
