a soil bacterium capable of degrading chitin on chitin agar plates was isolated and identified as bacillus pumilus isolate u5 on the basis of 16s rdna sequence analysis. in order to optimize culture conditions for chitinase production by this bacterium, a two step approach was employed. first, the effects of several medium components were studied using the plackett-burman design. among various ...

Background: Hydrocarbons degradation is principally achieved by microorganisms in natural environments. The extent of hydrocarbons biodegradation is mainly conditioned by environmental factors and its success depends on the optimal condition for the crude oil degrading isolates. Objectives: The aims of the current study was to isolate and identify crude oil degrading bacterium from surface sed...

The main theme of the thesis is to interpret Naxi (Na-khi) religious texts from a historical and a comparative perspective in the social and cultural context in the region of south-west China. There are two parts: Part I. Social Anthropology and the study of the Tibeto-Burman-speaking peoples; Part II. Naxi writing and the interpretation of Naxi religious texts. Part I (Chapters 1 to 5) focuses...

Box and Hunter (1961) made an important observation that any fractional factorial design of resolutionR has the property that when projected onto anyR 1 factors it becomes a full factorial design. This has a signi cant implication for statistical analysis. We observe that the Plackett-Burman and related designs have a hidden projection property with an analogous implication for the analysis. Be...

This paper discusses the diachronic development of non-structural case marking in TibetoBurman and in computer simulations of language evolution. It is shown how case marking is initially motivated by the pragmatic need to disambiguate between two core arguments, but eventually may develop flagging functions that even extend into the intransitive domain. Also, it is shown how different types of...

Plackett-Burman design, central composite design and response surface analysis were carried out with the aim of optimizing culture conditions for -mannanase production from Bacillus licheniformis TJ-101. Screening experiments of Plackett-Burman design were firstly employed to evaluate the effects of 16 variables on -mannanase production. The four identified significant variables, i.e. the conce...
