The Phonology And Morphology Of The Dar Daju Daju Language

A recurring theme among linguists is the need for more languages to be analyzed and more descriptions to be available for a variety of reasons. The main purpose of this thesis is to provide essential information on the Daju Dar Daju language of Chad, Africa that will assist in future language development work among the Daju Dar Daju people as well as to provide additional information for possible future work among related languages. Very little work has been done on the Daju languages as a whole and to date almost nothing on the Dar Daju Daju. The Dar Daju Daju of Chad are a traditional oral society who have, in recent years, expressed a strong desire to see their language developed in print form. In the past two years a working orthography has been established and a limited number of publications printed. During this time literacy work also began among the three language varieties of the Dar Daju Daju. The information provided by this thesis will likely prove helpful in current future literacy work being done as well as in future publications. The description I will present is limited to the phonology and morphology of the Dar Daju Daju language and is not intended to be an exhaustive presentation of its gramamr. The morphology discussed includes the morphology of pronouns and demonstratives, nominal morphology and lastly, verbal morphology. Information as to its relationship with and similarities to other Daju or Eastern Sudanic language varieties is included where applicable. Though a limited amount of linguistic information has been published in other Daju language varieties, no publication of linguistic work has been previously made available on the Dar Daju Daju language

Piezoresponse imaging of lead zirconate titanate microfibers and numerical analysis of its electric field distribution

Piezoresponse imaging technique was transplanted from thin film to probe polarization domains and local properties in single electrospun lead zirconate titanate microfibers. The corresponding electric field distribution was numerically analyzed. The biased conic tip is found to produce a field that peaks on its apex and decreases rapidly toward the bottom metal electrode. A strong field exists only in a thin surface region and cannot pole the affected domain even with its magnitude of 108 V/m on the fiber surface

Low-Temperature Electronic Properties of Electrospun PAN-Derived Carbon Nanofiber

Although carbon nanofibers might have wide potentials in applications, most of their physical properties have yet to be investigated. This paper reports on the low-temperature electronic transport properties of an electrospun polyacrylonitrile-based carbon nanofiber, with its mean diameters around 120 nm. The resistance of the carbon fiber was measured using the four-point probe method from 295 down to 15 K. The semiconducting nature of the fiber is revealed by its positive temperature coefficient of conductance, i.e., an increase in conductivity with the temperature. The conductivity (σ) depends on temperature according to the relation, σ = 5768T 0.338exp(-2 x 10-6 eV/kT), suggesting an almost zero bandgap and a strong temperature dependence of carriers mobility. Such temperature dependence of conductivity is very similar to that found in carbon microfibers, and can be explained using a simple two-band model with temperature-dependent mobility

Early Stages on the Graphitization of Electrostatically Generated PAN Nanofibers

Carbon nanofibers were produced from polyacrylonitrile/N, N-Dimethyl Formamide (PAN/DMF) precursor solution using electrospinning and vacuum pyrolysis at temperatures from 773K to 1273K for 0.5,2, and 5 hours, respectively. Their conductance was measured. It was found that the conductivity increases sharply with the pyrolysis temperature, and increases considerably with pyrolysis temperatures of 873, 973 and 1073K, but varies, less obviously, with pyrolysis time at the higher pyrolysis temperatures of 1173 and 1273K
