18. Superior Underwater Vision in Humans
Abstract : Amphibious vision is accomplished in many animals by special optical and physiological adaptations in the eyes. However, human eyes are considered to be adapted to a life in air since our curved outer cornea – which is used to refract more than two-thirds of the incoming light on land – becomes useless underwater.

19. On the lateral organisation of the thylakoid membrane
Abstract : In this work the lateral heterogeneity of the thylakoid membrane was investigated by quantifying the amount of photosystem I (PSI), photosystem II (PSII) and some PSII complexes and PSII proteins in different domains of the thylakoid. Grana, grana core, grana margins and stroma lamellae + end fractions were obtained by sonication and separation in a non-detergent, aqueous polymer two-phase system. READ MORE

20. Distribution and Biogeochemical Cycling of Arsenic In Grey and Brown Sand Aquifers in the Bengal Delta Plains (India)
Abstract : An elevated level of Arsenic (As) in aquifers from India and Bangladesh affecting the human health has been widely reported since the late 1980s. The thesis aim is to investigate the present status of As contamination and biogeochemical cycling with direct role of diverse indigenous bacterial communities in As cycling in the Bengal Delta Plain (BDP) aquifers in Nadia district, West Bengal (India).
