Abstract Principles of morphotactics are a major source of morphological diversity amongst the world’s languages, and it is well-known that languages exhibit many different types of deviation from a canonical ideal in which there is a unique and consistent mapping between function and form. In this paper we present data from Murrinhpatha (non-Pama-Nyungan, northern Australia) that demonstrates a type of non-canonical morphotactics so far unattested in the literature, one which we call positional dependency. This type is unusual in that the non-canonical pattern is driven by morphological form rather than by morphosyntactic function. In this case the realisation of one morph is dependent on the position in the verbal template of another morph. Thus, it is the linearisation of morphs that conditions the morphological realisation, not the morphosyntactic feature set. Positional dependency in Murrinhpatha thus expands our typology of content-form interactions and non-canonical morphotactics with implications for our understanding of morphological structure cross-linguistically.

Plasma electrolytic oxidation (PEO) of 5754 aluminum alloy in a tartrate electrolyte was carried out to form a base layer. Composite fluoropolymer coatings were obtained on the base layers in two ways allowing the formation of two different types of morphological structure: a continuous polymer film and a multimodal islet relief. The resulted coatings exhibit substantially different wettability along with high level of barrier properties.

And Function

Collagen is the core protein of connective tissues: skin, bone, tendon, base membrane, etc. Collagen is actually a family of several different genetic types. Currently they are known, in vertebrates, at least 27 different types of collagens, which shows a remarkable diversity in molecular and supramolecular organization of the tissue distribution and function, discovered and developed over 45 years. They were studied, in detail, 12 main types. Collagen-based bioproducts can be produced in a variety of molecular structures (micro and nano structures) in powder form, hydrogels and injectable solutions, films, membranes and matrices, etc. This paper presents the drying processes that are selected depending on the nature of the extract (undenatured or denatured) and morphological structure bioproduct or sponge, fibers or membranes. The most frequently used procedures for drying are freeze-drying and free drying at a temperature of approx. 25 ° C. Both processes produce no distorts to the extracts They are presented bioproducts derived from collagen which are used in medicine.

ABSTRACT Morphological characters of species are essential for assessing the functional structure of a fish assemblage, since differences between them, for example in body shape, are related to many functional and ecological traits (e.g., swimming, search for food, striking and capturing prey, evading predators, spawning). Globally, tidal flats are relevant to fish assemblages by offering feeding, refuge, and reproduction grounds. To analyze the morphofunctional structure of the fish assemblage from a tidal flat on the Brazilian coast, we conducted standardized sampling using nine different fishing gears. The geometric morphometric method was applied to describe the fish shapes and verify the morphological structure of the assemblage. Here, we present the influence/susceptibility of each gear type on the morphological diversity of the fish assemblage. The results indicated that beach seine, otter trawl, marginal encircling gillnet, and fish traps, together, were the most effective gears to represent the maximum morphological variability of fish inhabiting that tidal flat. Moreover, the assemblage showed high morphological redundancy considered as a resistance of the ecosystem for avoiding functional diversity loss, emphasizing the importance of complementary gear use when determining fish assemblages in a conservation context.

Semantic Agreement

Agreement minimally involves interaction between morphology and syntax, as a target’s features vary according to the morphological form of a controller in a given syntactic context. However, semantics can also play a role, and the term “semantic agreement” has been used to describe various constructions where morphosyntactic feature values of the agreement target do not match the formal features of the controller, reflecting instead meaning-based properties of the noun. In this paper, we deconstruct instances of “semantic agreement,” as there is good evidence to believe that more than just the semantics is involved in the agreement process. In some cases, e.g. Russian hybrid nouns like vrač ‘doctor’, the local context provides the agreement features, giving a type of “pragmatic agreement”. In other cases, socio-cultural information plays a role, showing a broader type of pragmatic agreement. In light of these observations, we offer a deconstruction of semantic agreement phenomena in order to show the complex ways morphology interacts with syntax, semantics, and pragmatics. Finally, we argue that the distinction between syntactic, semantic, and pragmatic agreement is paralleled by (and benefits from) earlier discussions of syntactic versus pragmatic control.

AbstractThe present paper treats the different types of formation and the inflectional patterns of the active imperfect of the verbs that in traditional grammar are known as verbs of the ‘2nd conjugation’ in the Peloponnesian varieties of Modern Greek (except Tsakonian and Maniot), mainly from a diachronic point of view. A reconstruction of the processes that led to the current situation is attempted and directions for further possible changes are suggested. The diachrony of the morphology of the imperfect of the ‘2nd conjugation’ in the Peloponnesian varieties involves developments such as morphologization of a phonological process and the evolution of number-oriented allomorphy at the level of aspectual markers, while at the same time offering interesting insights into the mechanisms and scope of morphological changes and the morphological structure of the Modern Greek verb. These developments can also offer important evidence for the process of dialectal differentiation of Medieval/‘Early Modern’ Greek.

Recent research has shown that the eucalypts of southern Australia have an unusual and apparently fire-adapted epicormic structure. By studying a range of myrtaceous species from northern Australia we hoped to determine if this structure was also present in northern eucalypts. We anatomically examined the epicormic structures from 21 myrtaceous species in 11 genera from the north of the Northern Territory, Australia. An extremely wide diversity of epicormic structures was found, ranging from buds absent, buds at or near the bark surface, to bud-forming meristems in the innermost bark. These Myrtaceae species displayed a far greater variation in epicormic structure than recorded in any other family. This is possibly a reflection of the importance of the resprouter strategy, a long fire history in Australia and the ecological diversification of the Myrtaceae. Nonetheless, all the investigated eucalypts (northern and southern) possessed the same specialised, apparently fire-adapted, epicormic structure. This is remarkably consistent given the taxonomic, geographical and morphological diversity of the eucalypts.

The Relationship

Abstract Cemento-enamel junction (CEJ) is an important anatomical structure of the tooth, which is located in the cervical part of the tooth between the crown and root, or at the contact point between the enamel which overlaps the tooth crown and cementum overlapping the root dentin. There are four possible relationships between two tissues that make the CEJ such as: the cement overlaps the enamel; the enamel overlaps the cement; the enamel and cement abut each other with no overlap; the enamel and cement are not in contact. The aim of this study was to determine the relationship between the enamel and cement which make the CEJ in different types of permanent teeth. The material consisted of 30 permanent teeth with intact CEJ. Staining of CEJ was carried out using the methylene blue. After staining, the tooth was washed under the running water and drying at room temperature. Each tooth was longitudinally cut in the vestibular-oral direction. Observation of CEJ was done with Leica light microscope and images were obtained using a Nikon camera. The results indicated that the most common form of CEJ between the cement and enamel in the region of CEJ was that cement and enamel abutted without overlap (36.7%), followed by the cement overlapping the enamel (33.3%), and the cases when a gap between the cement and enamel (16.7%) was present, and when the enamel overlaped the cement (13.3%). Because of the morphological diversity of CEJ, careful performing of dental interventions in the region of tooth neck is necessary because they may change the morphology of this region, induce the pathological processes and hypersensitivity of teeth.

Ошибки при выборе устойчивых/несвободных выражений характерны для речи иностранцев даже с высоким уровнем владения русским языком. Частотность этих ошибок вызвана широкой распространенностью таких выражений в языке и связана с их семантической непрозрачностью и нередкими расхождениями между внешним морфологическим оформлением и реальной грамматической функцией. Анализ ошибок в использовании иностранцами несвободных выражений на материале Русского учебного корпуса показывает, что трудности у студентов РКИ могут быть разной природы и возникают при использовании в речи устойчивых выражений самых разных типов. Использование таких корпусных ресурсов, как Национальный корпус русского языка и Ruskell, может помочь студентам в работе над развитием навыков правильного употребления русских несвободных выражений. В статье представлены рекомендации по выбору ресурса и ожидаемые ограничения в их использовании. Errors made in choosing or structuring a set expression are quite common for foreign speakers of Russian even for those with a good mastering of the language. The large amount of these errors is caused by the frequency of set expressions in the language, and is associated with their semantic opacity and with well-known discrepancies between their morphological form and grammatical function. These discrepancies can vary and are depend on the degree of freedom of the expression’s elements (i.e. on the type of the expression).The analysis of errors in set expressions in the Russian Learner Corpus; has demonstrated that the difficulties that the students face can be of different nature and are manifested in various types of expressions. Use of corpus resources such as the Russian National Corpus and Ruskell may help improve students’ proficiency in Russian set expressions. The applicability and effectiveness of these resources varies for set expressions of different types. The paper provides recommendations for choosing efficient corpus recourses, and indicates restrictions of different corpora.

Restoration works on an 11 km long reach of the Spree River near Cottbus in Germany were accomplished in 2014. The overall objective was to improve the biodiversity, changing the morphological structure from a straight single-thread river to a braiding one with reshaped thalweg, and creating zones with varying flow velocities required for fish spawning. Several interventions were made, among which also two types of groynes were constructed along the reach: impermeable stone groynes, with an inclined crest so that only the tip is typically submerged during normal flow conditions, and wooden groynes made of several large trunks, which are mainly submerged at normal flow conditions. To compare local morphodynamic effects caused by the different types, flow velocities and bed topography were measured at distances of 12 m upstream and 16 m downstream of two selected groynes. The vertical profile was captured by measuring at five levels above the bed. Bed material was sampled at several locations around the groynes. The analysis of the measurements showed the effect of each groyne type on the flow velocity, bed topography and bed material. Furthermore, the differences in the effects of each groyne type on the flow, bed topography and bed material were highlighted.

This paper addresses and targets morpheme segmentation of Kannada words using supervised classification. We have used manually annotated Kannada treebank corpus, which is recently developed by us. Kannada bears resemblance to other Dravidian languages in morphological structure. It is an agglutinative language, hence its words have complex morphological form with each word comprising of a root and an optional set of suffixes. These suffixes carry additional meaning, apart from the root word in a context. This paper discusses the extraction of morphemes of a word by using Support Vector Machines for Classification. Additional features representing the properties of the Kannada words were extracted and the different letters were classified into labels that result in the morphological segmentation of the word. Various  methods for evaluation were considered and an accuracy of 85.97% was achieved.
