In this paper we present the results of a field study of Avaaj Otalo (literally, "voice stoop"), an interactive voice application for small-scale farmers in Gujarat, India. Through usage data and interviews, we describe how 51 farmers used the system over a seven month pilot deployment. The most popular feature of Avaaj Otalo was a forum for asking(More)
Any national cuisine is a sum total of its variety of regional cuisines, which are the cultural and historical identifiers of their respective regions. India is home to a number of regional cuisines that showcase its culinary diversity. Here, we study recipes from eight different regional cuisines of India spanning various geographies and climates. We(More)
Much of the mobile work by HCI researchers explores a future world populated by high-end devices and relatively affluent users. This paper turns to consider the hundreds of millions of people for whom such sophistication will not be realised for many years to come. In developing world contexts, people will continue to rely on voice-primary interactions due(More)
Eubacterial peptidyl-tRNA hydrolase is an essential enzyme that hydrolyzes peptidyl-tRNAs that are released into the cytoplasm because of premature termination of translation, expression of minigenes, and action of lincosamide and macrolide antibiotics. This averts the arrest of protein synthesis caused by depletion of free tRNA. Recently, we demonstrated(More)
Forty percent of the world's population, including a significant portion of the rural and urban poor sections of the population in India, does not have access to reliable electricity supply. Concurrently, there is rapid penetration of battery-operated portable computing devices such as laptops, both in the developing and developed world. This generates a(More)
Spoken Web proposes to build an alternate web for the underprivileged population that is yet untouched by the enormous benefits of Internet and World Wide Web. Just over 22% of World's population today has access to Internet [Stats 2008]. The remaining 78% either cannot afford computers or high end mobiles, or are textually illiterate or simply reside in(More)
Delivering new technology solutions in a well established IT-educated consumer market largely depends on the usefulness and usability of the solution. However, this is very different from delivering ICT solutions in developing regions where there are multiple factors that affect technology adoption, which seem to be at least as important as the technology(More)
Leishmania donovani ADF/cofilin (LdCof) is a novel member of ADF/cofilin family. LdCof depolymerizes, but does not co-sediment with, rabbit muscle actin filaments. Its F-actin depolymerizing activity is pH independent. Further, it possesses weak F-actin severing activity. In order to better understand its characteristic properties, we have determined the(More)
Toxoplasma gondii ADF (TgADF) belongs to a functional subtype characterized by strong G-actin sequestering activity and low F-actin severing activity. Among the characterized ADF/cofilin proteins, TgADF has the shortest length and is missing a C-terminal helix implicated in F-actin binding. In order to understand its characteristic properties, we have(More)
