This study, carried out in different Baram-speaking areas in the Gorkha District (Western Nepal), is based on the analysis of data collected by the LEDBL team between May 2007 and April 2010, employing tools such as sociolinguistic questionnaires and Swadesh Wordlist, as well as interpersonal interactions and conversations with members of the Baram community and Baram language consultants. The main objectives of this sociolinguistic study were to: i. Identify the areas of Baram settlement; ii. Gather information about Baram speakers; iii. Collect details about various sociolinguistic aspects of the language such as the language name, language variation, knowledge and use of the language, language attitudes, vitality and maintenance, and the level of language endangerment.
Limbu is a Kiranti language native to eastern Nepal and the western fringe of Sikkim.

Agreement is partly determined by grammatical function and argument structure, but in many instances the functional prominence of the agreement controller—determined by focus and referential features, including respect—overrides syntactic prominence. This is particularly clear when possessors internal to an argument or adjunct can control agreement, even though viable alternatives appear to be available. The functional prominence of the internal possessor also appears to have a syntactic correlate: the possessor that controls agreement may be in a more prominent position within the phrase headed by the possessed nominal, and this is what enables it to participate in clause-level syntactic processes.

This paper describes the extension of automated text and corpus annotation in Nepali from POS tags to lemmatisation, enabling a more complex set of corpus-based searches and analyses. This work also addresses certain practical compromises embodied in the initial tagging of the NNC. First, some particular aspects of Nepali morphology-in particular the complexity of the agglutinative verbal inflection system-necessitated improvements to the underlying tokenisation of the text before lemmatisation could be satisfactorily implemented. In practical terms, both the tokenisation and lemmatisation procedures require linguistic knowledge resources to operate successfully: a set of rules describing the default case, and a lexicon containing a list of individual exceptions: words whose form suggests a particular rule should apply to them, but where that rule in fact do...

Titanium metal matrix composites reinforced with continuous SiC/C filaments were analysed in different densification conditions. The results show that during processing, densification occurs by several mechanisms including a complex elasto-viscoplastic flow and diffusion bonding. The matrix consolidation depends on many processing conditions such as pressure and temperature, mainly. Using correct conditions of pressure and temperature, the titanium matrix composites produced by this process present a good matrix consolidation without porosity and a weak interaction between matrix and fiber. These good agreements between matrix consolidation and weak chemical interaction between matrix and fibre are obtained when pressures up to 150 MPa and temperatures below β-transus are applied. In these conditions, supplementary heat treatments can be performed either in alpha or beta domains.

Our understanding of ecosystems is guided by the principle that living entities exist through a network of interrelationships. The domains of biological, linguistic and cultural diversities also hold a mutually reinforcing relationship. Data from Nepal would appear to support this trend: the country is home to over 5,400 species of higher plants and 850 species of birds, 2.2 % and 9.4 % of the world’s totals respectively (Shrestha and Vimal 1993: 3), a high level of biodiversity per unit area matched by a similar rate of linguistic and cultural variation. In the powerfully written Vanishing Voices, Daniel Nettle and Suzanne Romaine make an explicit link between language survival and environment issues: the extinction of languages is part of the larger picture of near-total collapse of the worldwide ecosystem (as cited in Yadava and Turin (2007)). Besides, various languages serve as symbols of ethnic identi...

Addition elements were used in a Cu-15,5Zn-8,0Al alloy to provide a comparison with the same alloy without microelement additions. The alloys were melted in an induction furnace of 24 kVA. After casting, the bulk samples of the alloys were homogenized. Then they were solution treated and hot-rolled followed by water-quenching to initiate the recrystallization. Finally, annealing produced at different temperature ranges was made in different samples in order to establish a law for the grain growth. Following the heat treatments, all annealed samples were examined by statistical metallography and the grain sizes were measured. After measurements, the same empirical law of grain growth was found for the different alloys and the ln [D-Do] x 1/T diagrams were plotted in order to establish the kinetic behavior. Based on the estimated values of the activation energy, important conclusions were obtained concerning the addition elements.

This corpus includes both spoken and written data, the latter incorporating a Nepali match for FLOB and a broader collection of text. Additional resources within the NNC include parallel data (English-Nepali and Nepali-English) and a speech corpus. The NNC is encoded as Unicode text and marked up in CES-compatible XML. The whole corpus is also annotated with part-of-speech tags. We describe the process of devising a tagset and retraining tagger software for the Nepali language, for which there were no existing corpus resources. Finally, we explore some present and future applications of the corpus, including lexicography, NLP, and grammatical research.
