This article explores the derivational morphology of P’urhepecha, especially with regard to verbal forms. P’urhepecha, or Tarascan, is an isolated Mesoamerican Ianguage of Central-Western Mexico, with about 200,000 speakers. An agglutinative type of language where suffixes are attached to the stem in a fairly regular fashion, P’urhepecha also has an extensive inflectional morphology with a system of cases, including genitive, locative, and residential. The present work presents an overall picture of the linguistic complexity of this intriguing language and its rich morphological resources through a review of some of the most common and productive types of derivational morphemes that occur as part of the verbal complex in P’urhepecha, including body-part suffixes, causatives, deictic suffixes, and other adverbial suffixes.

This work presents a relationship between the thermal properties in different polyethylene samples analyzed by differential
scanning calorimetry (DSC). The morphology and structural changes were studied by transmission electron microscopy (TEM).
A preparative method involving surface etching was used to obtain surface replicas. The main morphological features of the
samples, characterized by lamellar structure, obtained in this work by TEM give values of mean lamellar thickness from 900
to 500 Ĺ in the highest branch content and molecular mass. Enthalpies of melting allowed to calculate crystallinity; given
values in the range from 47 to 68%.

Precipitation of a sparingly soluble salt in the annular gap of a continuous Couette reactor with two unpremixed feeds has
been experimentally investigated. Barium chloride and sodium sulphate in stoichiometric ratio are fed at different flow rate
in the lower part of the reactor; different feeding modes have been considered. The dependence of precipitation yield, mean
crystal size and particle size distribution on rotation speed, axial flow rate and initial supersaturation ratio has been
studied. Depending on the operating conditions crystals with different morphologies have been obtained, varying from dentritic
tabular crystals to complex pyramidal ones and from single crystals to aggregates.
A collection of 35 accessions of the tetraploid wild wheat Aegilops geniculata Roth (MM, UU) sampled in northern Algeria was evaluated for morphological and biochemical variability. Morphological and ecological analyses based on morphological traits and bioclimatic parameters, respectively, were assessed using principal component analysis (PCA). Accessions were differentiated by width characters, namely spike’s width, and a weak relationship between morphological traits and ecological parameters was found. Polymorphism of high molecular weight (HMW) glutenin subunits was carried on by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). Among accessions analyzed, 27 alleles were identified at the two loci Glu-M1 and Glu-U1: resulting in twenty-nine patterns and a nomenclature was proposed. Two alleles at the Glu-U1 locus expressed a new subunit with a slightly slower mobility than subunit 8. These results provide new information regarding the genetic variability of HMW glutenin subunits, as well as their usefulness in cultivated wheat quality improvement.
The DSC characterisation of the morphology of the metastable a phase of stoichiometric nickel sulphide was carried out using
two calorimeters; a TA Instruments 2920 MDSC and a Perkin Elmer DSC-7, and two quenching histories. Based on these quenching
histories, significant differences were observed in the heat flow curves, including the observation of a second exothermic
peak which is tentatively assigned to be a metastable phase to metastable phase transformation. The kinetic constants for
the a to b recrystallisation were determined as a function of degree of conversion using a mechanism free isoconversional
model. Variations in the values of the kinetic constants were also ascribed to the quenching histories. Although the differences
in morphology observed were ascribed to the processing history, the shift in the position of the a to b recrystallisation
peak was partially attributed to the thermal resistances of the instruments used.
The paper explores the nature of cross-linguistic influence in morphology. 30 Estonian (a closely related L1) and 30 Russian (a non-related L1) beginning and advanced learners of L2 Finnish were tested for their skills in nominal inflection in three different tasks: separate nouns of morphophonologically varying inflectional categories to be inflected in several plural case forms in writing, the same nouns to be used in a narrative writing task and in an oral inflection task. The nouns were selected to represent various degrees of inflectional and/or semantic similarity between Finnish and Estonian (for Russian no such similarity exists). The results indicate that—in opposition to what has been previously claimed—not only does cross-linguistic influence exist within the domain of morphology but it also varies systematically across inflectional categories and between groups at different levels of general skills in Finnish.
The Finnish language has a very extensive inflectional morphology, whereas Vietnamese, as an isolating language, has no inflection at all. Therefore, the major challenge encountered by Vietnamese immigrants learning Finnish is to develop awareness of the existence, function and use of inflection. This paper examines how this process manifests itself in native-non-native speaker (NS-NNS) conversations during the initial stages of second language acquisition. All the negotiation sequences including overt signals of problems in understanding were subjected to a closer analysis, and the linguistic modifications performed to solve the problems were analysed on the level of both interaction and grammar. In this paper, the focus is on the observable signs of gradually growing morphological awareness, and especially the receptive segmenting skills of the learners.
