AbstractThe Lower Son Valley is generally overlooked despite a lengthy history of archaeological and geological studies in the adjacent Middle Son Valley. However, recent explorations in the former have yielded a large number of Palaeolithic and microlithic sites. This paper provides an initial report on Doma, a newly discovered site with the first-known stratified bifaces in this part of the valley. The site preserves multi-period technologies in different contexts including terminal Acheulean/early Middle Palaeolithic, and Upper Palaeolithic (all tentatively assigned based on respective typologies). Preliminary field observations are presented on the sedimentary sequence, archaeological surveys, topographical mapping, raw material, and the overall palaeoanthropological assessment of Doma. The raw material utilised at the site is primarily porcellanite, derived from exposures of the Semri Group of the Vindhyan Supergroup. The oldest Palaeolithic evidence at Doma broadly resembles Late Acheulean sites dated to ∼140-120 ka in the nearby Middle Son Valley. The Pleistocene sediments here also yielded mammalian fossil specimens such as long bone fragments, dental specimens and antler fragments. Along with the lithics and fossils, the site also preserves datable sedimentary sequence with calcrete, all key proxies to develop a testable model of technological transitions within a palaeoenvironmental framework, in the future.

Background: Acne vulgaris is a very common dermatological problem of adolescence since the time immemorial. However, it is neither life threatening nor is a physical disability, but acne affects social and psychological functioning. Acne vulgaris is multifactorial, apart from basic factor of hormonal change and bacterial outbreak; there are several other factors that may influence the prevalence of acne.Methods: In the present study, populations were assessed for influence of various factors on acne prevalence. This cross-sectional study was a population based field study intending to discern the factors that influence the prevalence of acne in adolescents. The study carried out from April 2016 to October 2016 in north central India. For this survey, questionnaires were design to cover all the required information regarding occurrence of acne that include factors like gender, age, skin type, complexion, season of occurrence, dietary habit etc.Results: Acne vulgaris appears to be influenced by gender, age, seasonal variations, breakout area, complexion, skin types and dietary habits. Further, the influence of dietary habit on acne, by the consumption of dairy products or high-carbon diet has also been evaluated. Apart from depicting the vulnerable range of age (p=0.003288), sensitivity on various skin types (p=0.00039) and complexion (p=0.001355) on the basis of gender; This Field study on Acne Vulgaris, also reveals that the season has inordinate role in acne pervasiveness (p=0.115731).Conclusion: This study is helpful in categorizing the risk factors and evidencing the afflictions of acne in population thus, contributing health care planning. Keywords: Acne, Prevalence, Risk factors, Post management.
