Abstract Atmospheric carbonaceous aerosols of South Asian origin have received immense concerns in the Anthropocene owing to their plausible role in the observed regional to inter-continental scale climate anomalies. Tracking plausible sources and alterations during their transport (secondary processes) are keys to understanding their net influence on regional climate. Here, we report elemental concentrations of C and N (TC and TN), their isotopes (δ 13 C, δ 15 N) and TC/TN ratios of bulk carbonaceous aerosol particles over northern Indian Ocean [Bay of Bengal (BOB) and Arabian Sea (AS)] collected as a part of integrated campaign of Aerosol Radiation Budget (ICARB) during March-May, 2006. In order to understand typical sources, we also measured same parameters of (i) aerosols emitted from typical bio-fuels conventionally burnt in north and northeastern India and (ii) aerosols particles present in ambient air over selected Indian cities during pre-monsoon season. Bulk aerosols over AS are characterized by significantly higher TC/TN ratios (~50±10) compared to aerosol over Indian cities (5.6±2.6) as well as over BOB (6.8±12.5), most likely due to having significant inorganic carbon contributed by mineral dust. δ 13 C of aerosols over AS and BOB do not show significant variation (−25.6‰±0.6, −26.5‰±0.8; n=24 and 21 respectively), however δ 15 N values showed a conspicuous difference between the two braches of northern Indian Ocean (10.6‰±2.7 over BOB and 1.4‰±3.3 over the AS). Depleted δ 15 N of aerosols over AS can be interpreted in terms of significant mixing of isotopically depleted nitrogenous compounds (NH 3 and NO xs ) emitted from the underlying (denitrifying) waters.

ELA-ICP-MS U–Pb zircon geochronology of regional volcanism hosting the Bajo de la Alumbrera Cu–Au deposit: implications for porphyry-related mineralization Abstract ELA-ICP-MS U–Pb zircon geochronology has been used to show that the porphyritic intrusions re-lated to the formation of the Bajo de la Alumbrera porphyry Cu–Au deposit, NW Argentina, are cogenetic with stratigraphically well-constrained volcanic and volcaniclastic rocks of the Late Miocene Farallón Negro Volcanic Complex. Zircon geochronology for intrusions in this deposit and the host volcanic sequence show that multiple mineralized porphyries were emplaced in a volcanic complex that developed over 1.5 million years. Volcanism occurred in a multi-vent volcanic complex in a siliciclastic intermontane

This report contains the result of a Master Thesis in which the usability aspects of innovative software design concepts on mobile phones are studied. More precisely, the study is divided in the following two main parts: 1) Threaded Messaging; the investigation of message threading as an innovative way of presenting text messages in a conversation like manner on mobile phones. 2) Usability versus Aesthetics; the investigation of how aesthetics of mobile phone Graphical User Interfaces (GUIs) influence peoples ’ judgements of usability and how people admit different levels of innovation and aesthetics in graphic design of mobile phones. In the study, three different mobile GUI prototypes were developed, which had different message handling solutions and varying levels of usability and aesthetics. The prototypes were then tested thoroughly in a usability lab using 16 participants from different age groups. The results elicited from the tests included that Threaded Messaging is a usable
