In the present study, the oleaginous fungus Mortierella alpina CBS 754.68 was screened for arachidonic acidproduction using inexpensive agricultural by-products as substrate. Four oilcakes were analysed to choose the best substrate among them. Sunflower oilcake was the most effective substrate for ARA production followed by soybean, colza and olive oilcakes. In the next step, seven variables in...

This book offers a comprehensive description of the phonetic and phonological features of Sumi, a Tibeto-Burman language of Nagaland, North-east India. It represents the first in-depth investigation of the acoustic phonetics and phonology of tone in Sumi, and is one of the first extensive acoustic descriptions of a language of Nagaland. The book describes the segmental phonology, syllable struc...

Aspirated fricatives are typologically rare in world’s languages, occurring mostly in the Sino–Tibetan languages. However, they are hitherto unreported in the Tibeto–Burman languages spoken in North–East India. In this study we present data from Bodo, a Tibeto–Burman language spoken in Assam, India and argue that the Bodo voiceless alveolar fricative is an aspirated voiceless alveolar fricative...

Alkaline protease producing microorganism Vibrio metschnikovii NG155, isolated from the soil samples of leather industry, having potential application in dehairing of animal skin was used in this study. To enhance the production of protease by this strain, various physical and nutritional factors were optimized using statistical methods like Plackett Burman and Response Surface Methodology. In ...

Plackett-Burman design and Box-Behnken response surface methodology (RSM) was employed to optimize the medium components for the chitin deacetylase (CDA) activity from Bacillus amyloliquefaciens Z7. Plackett-Burman design was applied to determine the specific medium components affecting CDA activity and found that starch, chitin and MgSO4 were critical in augmenting CDA activity. These signific...

A quantitative analysis of a trans-generational, conversational corpus of Chintang (Tibeto-Burman) speakers with community-wide bilingualism in Nepali (Indo-European) reveals that children show more code-switching into Nepali than older speakers. This confirms earlier proposals in the literature that code-switching in bilingual children decreases when they gain proficiency in their dominant lan...

This paper describes optimization method that combines the Plackett-Burman design, a factorial design and the response surface method, which were used to optimize the medium for the production of L-asparaginase by Serratia marcescens SB08. Four medium factors, from out of 11 medium factors, were screened by Plackett-Burman design experiments and subsequent optimization process to find out the o...

An unequal contribution of male and female lineages from parental populations to admixed ones is not uncommon in the American continents, as a consequence of directional gene flow from European men into African and Hispanic Americans in the past several centuries. However, little is known about sex-biased admixture in East Asia, where substantial migrations are recorded. Tibeto-Burman (TB) popu...
