Параллельные формы множественного числа в осетинском языке встречаются как у заимствованных слов, у которых могут быть приметой ассимилированности слова, так и в парадигме склонения исконных слов. Такие формы отмечены преимущественно в терминосистеме родства, анализ которых позволяет уточнить представления об этимологическом развитии отдельных слов и общегрупповых морфологических, семантических процессах в системе терминов родства. Экстраполяция данных других языков, а также диахронический анализ осетинского материала позволяет восполнить недостающие элементы матрицы. Вывод о языковой потребности маркировать морфологическим способом различные значения, оформлять собирательное плюрального, отмеченного в ряде языков для различения простого множественного и собирательного, а также обозначить стилистическую принадлежность той или иной формы основывается на сопоставлении параллельных форм множественного числа терминов родства. Особое внимание уделяется отсутствию регулярной формы множественного числа у осетинской лексемы ус “жена”. Наличие параллельных форм может отражать первоначальное существование паронимов, у которых, ввиду минимальности семантической дистанции между ними и высокой омонимичности, происходила контаминация парадигм склонения. Пароним, оформленный суффиксом терминов родства, мог обозначать “жена”, соответственно, пароним без форманта мог употребляться в значении “женщина”. На образование форм множественного числа могли оказывать влияние и другие языковые процессы. И возникновение, и утрата дублетных форм могли быть обусловлены экстралингвистическими факторами. Parallel plural forms in the Ossetian language are found both in the borrowed words, which may sign the degree of assimilation of a loan, and in the declension of the original words. Such forms are noted mainly in the system of kinship terms, their analysis makes it possible to clarify ideas about the etymological development of the individual words, about the general development of morphological system, and semantic processes in the system of terms of kinship. Extrapolation of data from other languages, as well as diachronic analysis of the Ossetian material, proper, makes it possible to fill in the missing elements of the matrix. Based on the comparison of the parallel forms of the plural of kinship terms, a conclusion is made about the linguistic need to mark different meanings in a morphological way, to indicate the collective plural, peculiar to a number of languages, to distinguish between the simple plural and the collective, and to designate the stylistic features of one form or another. Particular attention is paid to the absence of a regular plural form in the Ossetian lexeme of affinity "us" - "wife". The presence of parallel forms may reflect the initial existence of the paronyms, in which, due to the minimal semantic distance between them and the high homonymy, there was a contamination of two declination paradigms. The paronym, formed by the suffix of the terms of kinship, could have meant “wife”, respectively, the paronym without the formant could have been used in the meaning of “woman”. The formation of plural forms could also be influenced by other linguistic processes. Both the emergence and loss of doublet forms could be accounted for by extralinguistic factors.

Bio-artificial polymeric systems are a new class of polymeric constituents based on blends of synthetic and natural polymers, designed with the purpose of producing new materials that exhibit enhanced properties with respect to the individual components. In this frame, a combination of polyvinyl alcohol (PVA) and chitosan, blended with a widely used antibiotic, sodium ampicillin, has been developed showing a moderate behavior in terms of antibacterial properties. Thus, aqueous solutions of PVA at 1 wt.% were mixed with acid solutions of chitosan at 1 wt.%, followed by adding ampicillin ranging from 0.3 to 1.0 wt.% related to the total amount of the polymers. The prepared bio-artificial polymeric system was characterized by FTIR, SEM, DSC, contact angle measurements, antibacterial activity against Staphylococcus aureus and Escherichia coli and antibiotic release studies. The statistical significance of the antibacterial activity was determined using a multifactorial analysis of variance with ρ < 0.05 (ANOVA). The characterization techniques did not show alterations in the ampicillin structure and the interactions with polymers were limited to intermolecular forces. Therefore, the antibiotic was efficiently released from the matrix and its antibacterial activity was preserved. The system disclosed moderate antibacterial activity against bacterial strains without adding a high antibiotic concentration. The findings of this study suggest that the system may be effective against healthcare-associated infections, a promising view in the design of novel antimicrobial biomaterials potentially suitable for tissue engineering applications.

AbstractThe problematic calcified cnidarian Cambroctoconus is described from the Henson Gletscher Formation (Cambrian Series 2, Stage 4–Series 3, Stage 5) of North Greenland, representing the first record from Laurentia of a genus otherwise recently described from China, Kyrgyzstan, and Korea. Internal molds produced by penetrative phosphatization mirror the pervasive pore system of the calice walls and septa. The pore system is compared to the network of gastrodermal solenia that distributes nutrients between polyps and surrounding stolon tissues in present day octocorals. In conjunction with the octagonal form of the individual coralla and eight-fold symmetry of septa, the pore system promotes assignment of Cambroctoconus to the Octocorallia, a basal clade in cnidarian phylogeny. Octocorals (‘soft corals’) are diverse in present day seas, but have a poor fossil record despite the general development of distinctive calcareous spicules. New taxa: Order Cambroctoconida new; Cambroctoconus koori new species.

Allomorphy is a reaction of the morphological system to problems that the unrestrained application of inflectional and other rules creates at the phonological level. These problems are dealt with in some cases but left unattended in others. A diachronic analysis of English reveals that phonemically conditioned allomorphy originates from gradual sound change, with the old and the new variant forming a morphophonological paradigm. The historical stability as well as the synchronic motivation of allomorphy are claimed to be frequency-based. The higher the frequency, the longer the life expectancy. Synchronically, there is a (language- and domain-specific) frequency threshold above which morphophonological variation occurs and below which it fails to occur. The underlying logic of the model is that frequency encourages lexicalization at all linguistic levels. The relative ease with which high-frequency items are accessed enhances the tolerance towards formal variation, hence the emergence of natural phonological rules. As the application of these rules is context-dependent, allomorphy arises as a context-sensitive process. Repair strategies are also argued to be under the sway of frequency. Epenthesis is found in highly frequent structures while coalescence is reserved for less frequent ones. Frequency also determines the scope and the optionality of morphophonological rules. Phonemically governed allomorphy is shown to be a member of the larger family of variationist phenomena which are bound together by their sensitivity to frequency.

The article elaborates a method for estimating the probabilities of occurrence of prognosticated events in future. On the basis of the data from the previous periods about prognosticating the relevant events, as well as the data about the trends observed at present, two matrices are formed, the product of which is the matrix for the prognosis errors committed by the individual or the expert. The article shows that the vector for probabilities of the prognosticated events is the eigenvector of the prognosis error matrix, which corresponds to its single eigenvalue. Application of the elaborated method is shown on the definite example for forecasting demand of new products.

&lt;p&gt;Shear zones are important conduits that facilitate the bidirectional migration of fluids and dissolved solids across the middle crust. It is a relatively recent revelation that mylonitic deformation in such shear zones can result in the formation of synkinematic pores that are potentially utilised in long-range fluid migration. The pores definitely influence a shear zone&amp;#8217;s hydraulic transport properties on the grain scale, facilitating synkinematic fluid-rock interactions and mass transfer. Our understanding of how exactly various forms of synkinematic porosity integrate with the kinematics and dynamics of shear zones is still growing. Here we show a previously undescribed form of synkinematic porosity in an unweathered, greenschist-facies psammitic ultramylonite from the Cap de Creus Northern Shear Belt (Spain). The sizeable, open pores with volumes &gt; 50k &amp;#181;m3 appear exclusively next to albitic feldspar porphyroclasts, which themselves float in a fine-grained, polymineralic ultramylonitic matrix that likely deformed by grain size-sensitive creep and viscous grain boundary sliding. The pores wrap around their host clasts, occupying asymmetric strain shadows and tailing off into the mylonitic foliation. A detailed analysis using high-resolution backscatter electron imaging and non-invasive synchrotron-based x-ray microtomography confirms that the pores are isolated from each other. We found no evidence for weathering of the samples, or any significant post-mylonitic overprint, unequivocally supporting a synkinematic origin of the pores.&amp;#160;&lt;/p&gt;&lt;p&gt;We propose that this strain shadow porosity formed through the rotations of the Ab porphyroclasts, which was governed by the clasts&amp;#8217; shapes and elongation. The ultramylonitic matrix was critical in enabling the formation of pores in the clast&amp;#8217;s strain shadows. In the matrix, the individual grains were displaced mostly parallel to the shear direction. As a consequence of clast rotation it can be expected that, in the strain shadows, matrix grains followed diverging movement vectors. As a result, phase boundaries in the YZ plane experienced tensile forces, leading to the opening of pores. We infer that this tensile decoupling among matrix grains established a hydraulic gradient that drained the matrix locally and filled the pores with fluid. The fact that the strain shadow pores remained open in our samples suggests a chemical equilibrium with the fluid. Pore shape and volume will have been subject to continuous modification during ongoing matrix deformation and clast rotation.&lt;/p&gt;&lt;p&gt;This form of synkinematic porosity constitutes a puzzling, yet obvious way to maintain surprisingly large pores in ultramylonites whose transport properties are otherwise likely determined by creep cavitation and the granular fluid pump (Fusseis et al., 2009). We envisage that the strain shadow megapores worked in sync with the granular fluid pump in the ultramylonitic matrix and, while the overall porosity of ultramylonites may be small, locally, substantial fluid reservoirs were available to service fluid-rock interaction and fluid-mediated mass transfer. Our findings add another puzzle piece to our evolving understanding of synkinematic transport properties of mid-crustal ultramylonites and fluid-rock interaction in shear zones at the brittle-to-ductile transition.&lt;/p&gt;

This introductory chapter provides a background of Maimonides and his code of Jewish law, the Mishneh torah. Maimonides applied the highest literary art to the highest of tasks: to bequeath, as philosopher-statesman, a law that would regulate the life of the individual and of society and move people closer to the knowledge of God. The result of that art is a book to be read and experienced, not just consulted. The central feature of Mishneh torah as a work of art is the casting of the commandments of the law in the form of the cosmos. The microcosmic form suggests, in the first place, that studying Mishneh torah, like the study of the universe, can be a way to the knowledge and love of God. On the plane of ideas, this form embodies the relationship between the ‘small thing’ and the ‘great thing’, between halakhah, on the one hand, and physics and metaphysics on the other. It depicts philosophy as the matrix of halakhah, reflecting the view of the relationship between philosophy and religion in the Islamic philosophers.

Abstract Background English materials for speech audiometry are well established. In Spanish, speech-recognition materials are not standardized with monosyllables, bisyllables, and trisyllables used in word-recognition protocols. Purpose This study aimed to establish the psychometric characteristics of common Spanish monosyllabic, bisyllabic, and trisyllabic words for potential use in word-recognition procedures. Research Design Prospective descriptive study. Study Sample Eighteen adult Puerto Ricans (M = 25.6 years) with normal hearing [M = 7.8-dB hearing level (HL) pure-tone average] were recruited for two experiments. Data Collection and Analyses A digital recording of 575 Spanish words was created (139 monosyllables, 359 bisyllables, and 77 trisyllables), incorporating materials from a variety of Spanish word-recognition lists. Experiment 1 (n = 6) used 25 randomly selected words from each of the three syllabic categories to estimate the presentation level ranges needed to obtain recognition performances over the 10 to 90% range. In Experiment 2 (n = 12) the 575 words were presented over five 1-hour sessions using presentation levels from 0- to 30-dB HL in 5-dB steps (monosyllables), 0- to 25-dB HL in 5-dB steps (bisyllables), and −3- to 17-dB HL in 4-dB steps (trisyllables). The presentation order of both the words and the presentation levels were randomized for each listener. The functions for each listener and each word were fit with polynomial equations from which the 50% points and slopes at the 50% point were calculated. Results The mean 50% points and slopes at 50% were 8.9-dB HL, 4.0%/dB (monosyllables), 6.9-dB HL, 5.1%/dB (bisyllables), and 1.4-dB HL, 6.3%/dB (trisyllables). The Kruskal–Wallis test with Mann–Whitney U post-hoc analysis indicated that the mean 50% points and slopes at the 50% points of the individual word functions were significantly different among the syllabic categories. Although significant differences were observed among the syllabic categories, substantial overlap was noted in the individual word functions, indicating that the psychometric characteristics of the words were not dictated exclusively by the syllabic number. Influences associated with word difficulty, word familiarity, singular and plural form words, phonetic stress patterns, and gender word patterns also were evaluated. Conclusion The main finding was the direct relation between the number of syllables in a word and word-recognition performance. In general, words with more syllables were more easily recognized; there were, however, exceptions. The current data from young adults with normal hearing established the psychometric characteristics of the 575 Spanish words on which the formulation of word lists for both threshold and suprathreshold measures of word-recognition abilities in quiet and in noise and other word-recognition protocols can be based.

This paper proposes the use of a signal acquisition and processing system based on an8×8planar array of MEMS (Microelectromechanical Systems) microphones to obtain acoustic images of a fan matrix. A3×3matrix of PC fans has been implemented to perform the study. Some tests to obtain the acoustic images of the individual fans and of the whole matrix have been defined and have been carried out inside an anechoic chamber. The nonstationary signals received by each MEMS microphone and their corresponding spectra have been analyzed, as well as the corresponding acoustic images. The analysis of the acoustic signals spectra reveals the resonance frequency of the individual fans. The obtained results reveal the feasibility of the proposed system to obtained acoustic images of a fan matrix and of its individual fans, in this last case, in order to estimate the real position of the fan inside the matrix.

Summary Characterization of reservoir deliverability is fundamental for the economic development of any field. In the Bakken, there is a need for reliable pressure-transient tests to provide the effective formation permeability of the fracture/matrix system in this formation for deliverability calculations. This effective permeability can then be compared with laboratory-measured core permeability of the matrix rock samples. This comparison is the basis for planning early-production options and subsequent enhanced-oil-recovery (EOR) decisions. This comparison is particularly important because of the influence of massive hydraulic-fracture stimulation on reservoir performance. Determining well-deliverability potential by conventional drill-stem tests (DSTs) or traditional wireline formation tests (WFTs) in the past has resulted in mixed success in the Bakken. On the other hand, the mini-DST has increased the reliability of pressure-transient tests because the formation interval of interest is produced at a precise constant rate into a chamber between two inflated packers with negligible wellbore-storage effects. Also, the operation of a mini-DST tool requires much less time than the classical DST, and multiple zones can be tested sequentially to assess the individual-zone deliverability. The mini-DST tool uses the conventional WFT configured with a dual-packer module and downhole pump. Tests are conducted by inflating the dual-packer module to isolate a 3-ft interval of the wellbore. The formation fluid is pumped out from the packer-isolated wellbore interval to conduct pressure-drawdown and -buildup tests in the interval. An overlay of all the pressure-drawdown and -buildup results from various intervals is compared on a single plot to identify the most productive interval. Finally, conventional pressure-transient analyses are performed to interpret all pressure-drawdown and -buildup tests. In this paper, we present several field tests that were analyzed both by the preceding procedure and by numerical simulation. The analyses of several mini-DST results have provided insight into a better understanding of the flow mechanism in the Bakken both during primary production and in forecasting various improved-recovery and EOR proposals. The results can also serve as a basis for test design in similar low-permeability reservoirs elsewhere.
