Published: August 2017

Objetivo: o objetivo deste trabalho foi realizar uma revisão de literatura acerca do freio lingual anômalo em lactentes, relacionando diagnóstico e tratamento. Revisão de literatura: esta anomalia limita os movimentos da língua durante o choro, lalação e pode gerar desconforto durante a amamentação. A metodologia do trabalho constituiu em buscas de artigos publicados em língua portuguesa e inglesa nas bases de dados Bireme, Google Acadêmico e PubMed, entre os anos de 2004 e 2016. Foram identificados 645 artigos através da combinação de palavras-chave, sendo que 29 foram utilizados por apresentarem resultados condizentes com o objetivo desta revisão. Considerações Finais: através dos estudos consultados não foi possível identificar um instrumento padrão-ouro que diagnostique a anquiloglossia em bebês, a despeito do fácil diagnóstico. Há controvérsias na literatura em relação ao tratamento por meio da frenotomia e sua contribuição para a melhora na amamentação, movimentos da língua e desconforto da mãe ao amamentar, embora grande parte dos estudos demonstre benefícios evidentes.

Published: August 2017

Introduction: We report a rare case of low-grade appendiceal mucinous neoplasm (LAMN) within an incarcerated Amyand’s hernia.
Case Report: he patient was admitted for an elective surgery due to an asymptomatic right-sided inguinal hernia. The operative findings were suggestive of an appendiceal mucocele. Appendectomy and herniorrhaphy were performed. The histology report revealed a low-grade appendiceal mucinous neoplasm. The patient had no clinical, biochemical or imaging signs of disease or hernia recurrence two years postoperatively.
Conclusion: Surgical treatment involves appendectomy and hernia repair, which is performed without the implantation of synthetic mesh. The possibility of finding an incidental neoplasm should be considered during the surgery of an Amyand’s hernia.

Published: August 2017

The purpose of this study was to determine and analyze the composition of Blighia sapida aril oil from Côte d’Ivoire and to compare its effects in diet to that of refined palm oil and olive oil.A quantity of dried Blighia sapida arils was ground to fine powder. Oil extracted from the powder was filtered and characterized. After that, three experimental diets differed by the type of oil which were mixed with the food (Blighia sapida aril oil or refined palm oil or olive oil) were prepared. Three groups of young rats (six per group) were fed ad libitum with the different diets during 28 days. At the end of the experimentation, food intake, body weight and alimentary efficacy coefficient were measured and compared.Chemicals analyze of the oil showed that it is oleic/palmitic/stearic oil. It contains low polyunsaturated fatty acids. The ratio of n-6/n-3 is 9.50 and the ratio unsaturated fatty acid/saturated fatty acid is 1.6. Food intake of the different group of rats was not significantly different (p>0.05) whatever the kind of oil in the diet. Body weight and alimentary efficacy coefficient obtained on rats fed with diet containing Blighia sapida aril oil were not significantly different (p>0.05) to that of rat’s which consumed diet containing palm oil.However, body weight and alimentary efficacy coefficient in case of olive oil consumption were high (p<0.05) than those obtained with consumption of Blighia sapida aril oil or palm oil.Blighia sapida aril oil and refined palm oil have practically the same nutritional value in alimentation while olive oil has more nutritional value.Refined Blighia sapida aril oil can enhance it nutritional value.
Critical factors besides treatment dose and duration need to be controlled in Pb toxicity tests in plant cell suspension cultures
Authors: Sychta Klaudia , Szklarzewicz Janusz , Słomka Aneta , Gregoraszczuk Ewa , Kuta Elżbieta
Published: August 2017

The study was designed to determine the proper conditions for suspension culture of Viola tricolor cells in toxicity studies of Pb at different concentrations (0, 200, 500, 1000, 2000 µM) and exposure times (24, 48, 72 h). By forming insoluble salts with ions from the medium, lead (II) nitrate added to the medium decreased the initial 5.7–5.8 pH of the medium, depending on the Pb salt concentration and light intensity.

In alamarBlue assays, we found no dose- or time-dependent effect of Pb on cell viability when we did not adjust pH and did not standardize the illumination conditions to correct the effect of lead-salt-induced turbidity.
When effective illumination was adjusted to correct for turbidity at the highest lead concentration and pH was adjusted to 5.7–5.8, cell viability decreased with the increase of Pb(NO3)2 concentration and with treatment time. These experiments demonstrate that the toxic action of lead on cells in suspension depends strongly on culture conditions, and not only on the metal concentration and duration of treatment.
Proposal of Objective Assesment of the Phenomenon of Light Passage Through Blackout Fabrics
Authors: Szkudlarek Joanna , Snycerski Marek , Owczarek Grzegorz
Published: August 2017

The paper presents some possibilities of measuring light passed through textile products applicable as sunshade window curtains. The existing measurement methods were analysed and a new method for measuring the barrier properties and transparency of flat textile products was proposed based on linear measurement. The idea of measurement was established for the purpose of identifying the optical properties of blackout fabrics applied as internal screens for public interiors. Preliminary research has shown that blackout fabrics obtained by weaving technology – so called weaving blackout (not a coated blackout) have a varied structure. In this case, the characteristics of this structure determine the level of barrier properties. The mechanism of light passing through such structures is special and requires specific measurement conditions. The paper presents an original research methodology dedicated especially for blackout fabrics. The new methodology and indicators for assessing the barrier effect in the VIS radiation band can be adopted by industry.
Effects of the Laundering Process on Dimensional and Physical Properties of Plain and Lacoste Fabrics Made from Modal/combed Cotton Blended Yarns
Authors: Çoruh Ebru
Published: August 2017

In this study, dimensional and some physical properties of plain (single jersey) and lacoste knitted fabrics made from 50/50 modal/combed cotton blended yarns (tex 21 and 15) were investigated. Twelve weft knitted fabrics were produced with two different structures and three different densities (loose, medium, tight). For physical properties, the fabric weight per unit area, fabric thickness, bursting strength, air permeability and dimensional stability were evaluated. We focused on the dimensional stability properties of outwear knitted fabrics. The total dimensional change of the fabric’s dimensions and structural properties were measured and evaluated after ten washing cycles and then flat dried. The results show that the weight per unit area, thickness, air permeability and dimensional stability values are independent of the yarn linear density, fabric structure and fabric density. Statistically evaluated using Design Expert Analysis of variance (ANOVA) software 6.06., test results show that dimensional stability is mostly effective for the bursting strength, air permeability and fabric weight per unit area.

Published: August 2017

In the research work presented, fabric made of wool was grafted with β-cyclodextrine (β-CD) using 1, 2, 3, 4 butanetetracarboxlic acid (BTCA) as a polyfunctional reagent. To reduce the grafting curing temperature, which could damage the wool fabric if too high, cyanamide (CA) in combination with ammonium dihydrogen phosphat (ADHP) were used as catalysts. The presence of cedar oil applied onto textile materials was determined by ATR FT-IR spectroscopy, as well as estimation of the add-on of cedar oil with the gravimetric approach, respectively. Finally the reduction in moths after being exposed to wool treated with a separate treatment formulation i.e. β-CD, cedar oil, and β-CD in combination with cedar oil was assessed visually after different time periods. Results showed that the wool after being treated with β-CD in combination with cedar oil shows significantly prolonged moth oppression activity compared to the wool treated with cedar oil only.

The success of suture yarn depends upon its tensile and bending properties. As sutures pass through the tissue, it should possess enough strength to hold the tissue together and should be flexible so as to be knotted. The aim of the present work was to improve the strength of silk suture without affecting its bending properties. Silk sutures were fabricated using a circular braiding machine. Structural variations were made by varying the diameter and by producing core sheath suture yarn. The resulting suture yarn is coated with chitosan – a biopolymer. The mechanical performances of suture materials coated with and without chitosan were studied and compared with commercial suture. It was observed that the suture with a core-sheath structure performed well during tensile and knot testing. The coarser yarns exhibited higher bending rigidity and lower knot strength than the finer suture yarns.

Published: August 2017

Current genetically modified organism (GMO) detection methods allow for sensitive detection. However, a further increase in sensitivity will enable more efficient testing for large grain samples and reliable testing for processed foods. In this study, we investigated real-time PCR-based GMO detection methods using a large amount of DNA template. We selected target sequences that are commonly introduced into many kinds of GM crops, i.e., 35S promoter and nopaline synthase (NOS) terminator. This makes the newly developed method applicable to a wide range of GMOs, including some unauthorized ones. The estimated LOD of the new method was 0.005% of GM maize events; to the best of our knowledge, this method is the most sensitive among the GM maize detection methods for which the LOD was evaluated in terms of GMO content. A 10-fold increase in the DNA amount as compared with the amount used under common testing conditions gave an approximately 10-fold reduction in the LOD without PCR inhibition. Our method is applicable to various analytical samples, including processed foods. The use of other primers and fluorescence probes would permit highly sensitive detection of various recombinant DNA sequences besides the 35S promoter and NOS terminator.

A Simplified Method for Analyzing Water Impact in the Initial Stages on an Elastic Rectangle Plate
Authors: Sun Hua , Wang De-Yu
Published: August 2017

For most flat-bottom marine structures, impact loads are generated by complex transient coupling effects of solid, air, and water. However, simplified forecasting methods to obtain impact loads and dynamic responses of flat-bottom structures by considering both hydroelastic and air cushion effects are rare. In this article, a new simplified analytical method of water impact on the elastic plate is proposed based on Verhagen's model for the rigid plate. The analysis is focused on the initial stage during which the highest hydrodynamic loads are generated. Interactions between the plate, the air, and the water are simulated and analyzed. Also, fluid-structure coupling results by simplified method are compared with numerical results from Arbitrary Lagrangian-Eulerian method in LS-DYNA code. Experimental results are used to validate the feasibility and accuracy of the simplified method. Water impact on plates with different drop heights, rigidities, and added mass is analyzed. The air cushion effect, elastic effect, and three-dimensional effect in the simplified model are also discussed.

1. Introduction

Over half a century, there has been more and more attention given to the phenomenon known as "slamming" which exists widely in both the natural environment and engineering application. As a complex transient process, slamming can be considered as a three-phase coupling model containing solid, liquid, and gas. Water entry problem is one of the most typical phenomena of slamming.

The problem of a rigid wedge entering water was studied in detail starting from the thirties of the last century. This study was motivated by the design of hydroplane landing on water. Von Karman (1929) first carried out an analytical study on water entry problem by potential theory. Considering the deformation of the water surface, Wagner (1932) extended the Von Karman model. In the following several decades, many complex models of water impact were developed by Wagner model (Hirano & Miura 1970; Armand & Cointe 1986; Cointe 1991). In addition, new models are proposed (Dobrovol' skaya 1969; Greenhow 1987; Howison et al. 1991; Muzaferija et al. 1997). More factors in the water impact problem were taken into consideration, including gravity (Greenhow 1987), liquid viscosity (Muzaferija et al. 1998), liquid compressibility (Korobkin 1996; Korobkin 1997; Campana et al. 1998), and so on.

Published: August 2017

High silicate zeolite ZSM-5 on the basis of SiO2–In2O3–NaOH with an organic structure forming agent tetrabutylammonium iodide (TBAI) was synthesized in the temperature range of T = 150–220°C, pH = 9-12, τ = 48-240 h. As initial components, silica gel MSKO containing 86% SiO2, tetrabutylammonium iodide (TBAI), chemically pure NaOH and metallic indium (In) were used which mixed by hydrothermal synthesis. At the end of the synthesis, the solid product was separated from the mother liquor, washed on the filter with distilled water from an excess of alkali and dried at 120 °C, calcined at 550 °C (16 h). The products of hydrothermal crystallization were determined by X-ray (RFA – on the device D2-Phaser "Bruker"), differential thermal (DTA- STA-449 F3 Jupiter NETZSCH), by X-ray diffraction (XRD of brand SRM-18) and infrared spectroscopy (IR on FTIR spectroscopy, Nicolefisio VSA) analysis methods. During the synthesis, it was experimentally established that at T = 200 °C; τ = 240 h; pH≈9-10 molar ratio of components 5.78SiO2∙0.058In2O3∙0.625Na2O∙0.11H2O∙0.95 ((C4H9) 4NJ) – MFI-type zeolite is crystallized. When comparing XRF data with literature data, they were referred to a type zeolite of ZSM-5 differing in high degree of crystallinity. The following chemical composition of the synthesized zeolite (wt.%) was established by the X-ray diffraction (SRM-18) method: SiO2 – 94.01; In2O3 – 4.92; Na2O – 1.06 corresponding to the formula 0.96Na2O:In2O3:88SiO2:10H2O.Forcitation:Samedov Kh.R., Mamedova U.A., Ragimov K.G., Jabbarova Z.A.

STUDY OF PROCESS OF HARDENING OF GYPSUM BINDERS, MIXING BY WATER, ACTIVATED BY MICROWAVE ELECTROMAGNETIC FIELD
Authors: Pavlenko Vyacheslav I. , Lapteva Svetlana N.
Published: August 2017

In this work, the effect of microwave (WV) radiation on the structure of distilled water is investigated, which is proved by the change in its electrical conductivity and coefficient of viscosity. Intensification of chemical processes with microwave radiation is the result of the electromagnetic field affecting the solvent and interacting substances. The process of hydration of semi-aquatic gypsum, which was closed by microwave-treated water with different values of the inputted energy in comparison with the control sample, was studied by the electric resistance measurement method. The kinetics of hydration and hardening of gypsum suspension was also studied. Differentiation methods yielded curves characterizing the stages of hardening of a gypsum binder: dissolution, colloidation, coagulation and crystallization. It is proved that, depending on the amount of microwave energy absorbed by distilled water, the duration of gypsum hardening processes changes. Optimal modes of microwave water treatment have been selected, which help to regulate the hardening process of gypsum binders. It is considered that to shutting gypsum binders, it is advisable to use a shutter with reduced electrical conductivity and, accordingly, with a minimum value of the viscosity coefficient. The destruction of the water structure or its change due to the influence of the microwave field will apparently influence the structure formation during hardening of the gypsum samples and, as a consequence, the change in their strength. The physic-mechanical properties of gypsum samples (bending and compression strength) are studied. The application of microwave radiation during processing of distilled water intensified the hardening process of semi-fluid calcium sulfate, contributed to an increase in the strength characteristics of the finished gypsum samples. The results of the experiment testify show the promising use of microwave water treatment, for the subsequent blocking of air binders and the obtaining building materials of greater strength.Forcitation:Pavlenko V.I., Lapteva S.N.

Published: August 2017

This paper reports the experimental study of destruction kinetics of oil hydrocarbons (engine oil of the M8 trademark) dissolved in water by dielectric barrier discharge in oxygen at the atmospheric pressure. The range of initial concentrations of oil in the aqueous solution was (12- 91) mg/l. All experiments were carried out under the applied voltage of 7.9 kV and discharge current of 0.45 mA (rms values) with a frequency of 50 Hz. The inputted power was 0.35 W/cm3.  The gas flow rate was 1 l/min. It was shown that the kinetics of oil decomposition can be formally described by the pseudo-first order law on oil concentration. The effective rate constant for decomposition of petroleum products was 0.0016 s-1. The rate of destruction in the investigated concentration range of M8 was varied in the range (3.8 - 28.9) · 10-6 mol / (l·min). The oil decomposition degree achieved 80 %, and the decomposition energetic yield was 0.16 molecules per 100 eV of inputted energy. The kinetics of the formation of ozone and carbon dioxide was examined as well. The obtained experimental data allowed to determine the degree of completeness of oil oxidation, which at the maximum was 54% (for carbon dioxide), this results indicates the formation of other carbon-containing compounds. The dynamics of the change in the pH of the treated solution is revealed. Under the experimental conditions, the pH was reduced from 6 to 4. It was found that the concentration of ozone formed in the reactor was deficiency for oil oxidative degradation. This results confirms that in the system are formed other active particles involved in the destruction of petroleum products, such as the OH* radicals and atomic oxygen. The possible mechanism of degradation processes is discussed.Forcitation:Grinevich V.I., Rybkin V.V., Lyubimov V.A., Gushchin A.A.

ALUMINUM HYDROXYNITRATES THERMOLYSIS

Published: August 2017

The thermolysis of various aluminum hydroxynitrates obtained by fresh precipitated Al hydroxide dissolution in a stoichiometric quantity of nitric acid has been studied. Under heating their multistage decomposition occurs including a gradual removal of chemically bonded water and denitration. According to thermal analysis data the composition of AlOH(NO3)2·mH2O, Al(OH)2NO3·nH2O and Al2(OH)5NO3·kH2O decomposition products at temperatures of 40-800 °С has been determined. It was ascertained that crystalline hydrate water segrerates under 157 °С (double stage). In the course of the primary dehydration the most loosely coupled crystal water (0.5-0.8 water molecules) escapes. Then the secondary dehydration – the remaining crystal water removal – takes place. This process becomes easier with increasing hydroxygroups quantity; it is confirmed by a proper temperature interval shift to lower temperatures. At 190-241 °С nitrate turns into nitrite (at approximately the same temperature for all studied compounds). Afterwards (249-376 °С) the denitration and chemically bonded water removal from salts anions take place. At that boehmite AlOOH is formed. The latter gives alumina transitional forms. In the time of Al(OH)2NO3·nH2O and Al2(OH)5NO3·kH2O thermolysis the partial removal of chemically bonded water overlaps on the denitration; so thermogravimetric curves have the most complex form. As a result all hydroxynitrates in contrast with aluminum nitrate are transformed into boehmite AlOOH that is confirmed by X-ray phase analysis. In addition, the composition of thermal decomposition products is confirmed by elemental analysis data.Forcitation:Kosenko N.F., Filatova N.V., Lipina E.A. Aluminum hydroxynitrates thermolysis. Izv.

GENTLE ACTIVATION OF POLYMINERAL SORBENT AND ITS INFLUENCE ON CLEANING PROCESS OF OIL-CONTAINING MEDIA FROM IMPURITY INGREDIENTS

Published: August 2017

An attempt to evaluate the effect of gentle activation of the surface of polymineral sorbent – blue clay with oxalic acid (Kdis = 5.6∙10-2) and sodium carbonate was carried out. The chemical structure of the initial and activated materials was established by the X-ray phase analysis. The prospect of their use for the sorption extraction of impurity ingredients from oil-containing media was revealed. An important rock-forming mineral in a composition of polymineral sorbent is montmorillonite. It was found that 45 mass% of the powder material has a particle size of 0.3-2.5 μm (quartz, cristoballite), 21% of the particles have a size of 5-10 μm and a small part (≤ 9%) is more than 10 μm. As a result of gentle activation of the sorbent with a 6% solution of oxalic acid, a clearer crystallized surface forms on which the effect of increasing the total pore size (100 nm - 2 μm) is observed. Such activated material is the meso- (20-500 Ǻ) type and macroporous type (> 500 Ǻ). The atomic composition of the renewed surface indicates the partial destruction of kaolinite during acid activation with an additional effect on impurity hydromica and a balancing increase in the mass fraction of quartz and saponite fractions (scaly particle form, 1-3 μm). The data of IR spectroscopic studies confirm the consistency of the judgments. Sequential activation with a solution of alkaline earth metals and sodium carbonate ensures the formation of tortuous pores and the production of disparate and relatively shallow (no more than 5 μm) particles in comparison with the original (globules up to 50 μm are encountered). The observed texture is a loosened land material of a complex chemical composition with the inclusion of natural grains of quartz, crystals (montmorillonite), fibrous structures and individual flakes. When 1% by weight of a polymineral sorbent based on montmorillonite and SiO2 was introduced into linseed oil, it was found that its treatment with 6% solutions of oxalic and succinic acid promotes an increase in the degree of purification from fatty acids to 40% and from peroxide compounds to 40%, then as gentle acid-alkaline activation of the sorbent provides the production of an oil-containing product with an even lower (by 5%) concentration of fatty acids.Forcitation:Nagornov R.S., Razgovorov P.B., Lepilova A.M., Stroganova Yu.I., Smirnov P.R., Kochetkov S.P.

HIGHLY ACTIVE CATALYSTS FOR OXIDATION OF THIOLS
Authors: Pletneva Inna V. , Gavrilov Yuriy A.
Published: August 2017

The problem of disposal of toxic and corrosion-active sulfhydryl substances (deodorization), natural hydrocarbons is relevant to operational and environmental aspects. One method of removing these impurities is catalytic oxidation to non-toxic disulfide form. The message shows the results of a comparative study of the oxidation reaction of thiols by oxygen to disulfides in hydrocarbon media, catalyzed by complexes of copper salts (I, II) with various nitrogen-containing bases. As nitrogen-containing ligands, mono - and diethanolamine with different C4-C18 hydrocarbon radicals were used. It is established that water-soluble catalyst composition on the basis of monoethanolamine and the hydrocarbon-soluble complex of copper Cu(II) with N-octadecyldiethanolamine exhibits low activity in the oxidation of 1-octanethiol. It was found the activating effect of HCl on the activity of catalysts in various hydrocarbons (model mixture, vacuum gasoil, naphtha and gas condensate of the Karachaganak field), which allows for an exhaustive oxidation of thiols with the initial concentrations ≥1000 ppm. However, the introduction of hydrogen chloride is accompanied by the appearance of corrosion. The introduction of corrosion inhibitors have led to the complete deactivation of the catalysts. The high-performance catalytic system based on CuCl2/CuO was designed, for which we found the optimum ratio of catalyst/inhibitor, to eliminate the corrosion effect while maintaining a high level of activity. The kinetics of the oxidation reaction of the sulfhydryl derivatives by oxygen was studied. It was found that regardless of the nature of the hydrocarbon media, for all investigated catalysts a zero order on concentration of the thiol and close to first order on the catalyst concentration is observed. The use of developed catalysts and purification technology in the industry will reduce the environmental hazard during the transportation and storage of petroleum products.Forcitation:Pletneva I.V., Gavrilov Yu.A.

Published: August 2017

In work the possibility of red sludge (waste of aluminum production by Bayer's method) to adsorb phosphate ions from water solutions at various concentration of ions and in the pH range from 3 to 10 is studied. Relevance of use of red sludge for receiving on its basis of sorbents is reasoned. For identification of the studied object the qualitative and quantitative composition of red sludge was established by the method of the X-ray phase analysis. The technique of red slage activation by hydrochloric acid, and also an adsorption technique of phosphate ions on the red sludge surface is described. Experimental studies of adsorption of phosphate ions on the surface of the red slage activated by hydrochloric acid depending on рН and concentration of initial solution were conducted. The dependence of adsorption phosphate ions on the red slage activated by НСl on рН and on the initial concentration of phosphate ions in solution is presented. These dependences of a relative fraction of distribution of various ions of phosphoric acid on рН are given in work. The form of ion phosphate having the greatest adsorptive activity on the red slage activated by hydrochloric acid in experimental conditions is revealed. Experimental data on dependence of adsorption of phosphate ions on their initial concentration in solution are described by Frumkin's isotherm. The constant of the adsorptive balance, limit adsorption, the parameter of intermolecular interaction of the adsorbed particles are calculated. Optimum conditions for adsorption of phosphate ions on red slage are established.Forcitation:Kramer S.M., Terekhova M.V., Artamonova I.V. Adsorption of phosphate ions on red sludge. Izv. Vyssh.

Translating instructive texts
Authors: Vandepitte Sonia
Published: August 2017

Starting with Werlich (1982), many researchers within text linguistics and document design see instructive texts as a category that is different from persuasive texts. Others do not include either in their main typologies (e.g. Bonnet et al. 2001).  This paper will claim, however, that instructions are a particular subtype of persuasive texts: instructing people is also persuading them to do something in a particular way or in a particular situation or in a particular order. Consequently, all features characteristic of persuasion (e.g. Aristotle 4th c. BC, Bettinghaus 1968, Dacheux 1994, Whalen 1996) also appear in instructive texts. Drawing from a learner corpus of materials used in the Trans-Atlantic Tech Writing / Translation Project (Maylath et al., 2005, in press), in which Flemish students translate English instructive texts written by American students into Dutch, the paper will discuss the problems involved in the translation of two relevant persuasive characteristics of instructive texts: expertise and positive audience-orientation. For the former, attention will be paid to message form, structure and strategy, while the latter will lead to considerations of both individual interpretation differences and cultural differences.
The Third Leg of Two-legged Lexicography
Authors: Tarp Sven
Published: August 2017

This article argues that the essence of lexicography is its capacity to satisfy the potential users’ punctual information needs in contrast to their global information needs. Simultaneously it shows that lexicographic theory, which so far has studied only two basic types of social situations where information needs may occur, the communicative and cognitive ones, should also study a third type of basic situations, which are referred to as operational user situations. On this basis, the article projects lexicography beyond the limits of known dictionaries considered as products of applied linguistics and discusses the relation that should be established between lexicography and other branches of human knowledge. It argues that lexicography, focusing on its core specialities, has a lot to contribute to these branches of knowledge. In this respect, it discusses not only traditional dictionaries but also the beneﬁt that authors of handbooks, manuals, how-to’s, user guides, textbooks and other types of texts may have from a renewed lexicographic theory that focuses on quick and easy access to data from which the potential users and readers may retrieve the information needed in speciﬁc situations. Finally, it argues that a number of university study programs may beneﬁt from short courses on the core specialities of lexicography.
The Discourse of Voicemail
Authors: Mishler Alan
Published: August 2017

This paper attempts to determine to what degree voicemail messages can be considered a discourse genre – that is, to what degree and in what ways they appear to be uniform across speakers. Thirty-seven voice messages were recorded from the cellular phones of three University of Michigan students. The messages were analyzed in terms of their overall structure, the discursive functions that were executed therein, and the speciﬁc words, phrases and prosodic strategies that were used to execute certain functions. The messages were found to have highly uniform openings and closings, and the message bodies were found to reduce to a small set of discursive functions. In addition, certain words, phrases and devices appeared frequently and in predictable locations within the messages. It is concluded that voicemail message-leaving is a highly structured act governed by conventions that arise both from face-to-face conversation and from the speciﬁc constraints of the medium.

A novel role for Ets4 in axis specification and cell migration in the spider Parasteatoda tepidariorum

Published: August 2017

Organizers play important roles during the embryonic development of many animals. The most famous example is the Spemann organizer that sets up embryonic axes in amphibian embryos. In spiders, a group of BMP secreting mesenchymal cells (the cumulus) functions as an organizer of the dorsoventral axis. Similar to experiments performed with the Spemann organizer, transplantation of the cumulus is able to induce a secondary axis in spiders. Despite the importance of this structure, it is unknown which factors are needed to activate cumulus specific gene expression. To address this question, we performed a transcriptomic analysis of early embryonic development in the spider Parasteatoda tepidariorum. Through this work, we found that the transcription factor Pt-Ets4 is needed for cumulus integrity, dorsoventral patterning and for the activation of Pt-hunchback and Pt-twist expression. Furthermore, ectopic expression of Pt-Ets4 is sufficient to induce cell delamination and migration by inducing a mesoderm-like cell fate.

Peptide signaling controls many processes involving coordinated actions of multiple organs, such as hormone-mediated appetite regulation. However, the extent to which the mode of action of peptide signaling is conserved in different animals is largely unknown, because many peptides and receptors remain orphan and many undiscovered peptides still exist. Here, we identify two novel Caenorhabditis elegans neuropeptides, LURY-1-1 and LURY-1-2, as endogenous ligands for the neuropeptide receptor-22 (NPR-22). Both peptides derive from the same precursor that is orthologous to invertebrate luqin/arginine-tyrosine-NH2 (RYamide) proneuropeptides. LURY-1 peptides are secreted from two classes of pharyngeal neurons and control food-related processes: feeding, lifespan, egg-laying, and locomotory behavior. We propose that LURY-1 peptides transmit food signals to NPR-22 expressed in feeding pacemaker neurons and a serotonergic neuron. Our results identified a critical role for luqin-like RYamides in feeding-related processes and suggested that peptide-mediated negative feedback is important for satiety regulation in C. elegans.

Distribution and biological implications of plastic pollution on the fringing reef of Mo’orea, French Polynesia
Authors: Connors Elizabeth J.
Published: August 2017

Coral reef ecosystems of the South Pacific are extremely vulnerable to plastic pollution from oceanic gyres and land-based sources. To describe the extent and impact of plastic pollution, the distribution of both macro- (>5 mm) and microplastic (plastic < 5 mm) of the fringing reef of an isolated South Pacific island, Mo’orea, French Polynesia was quantified. Macroplastic was found on every beach on the island that was surveyed. The distribution of this plastic was categorized by site type and by the presence of Turbinaria ornata, a common macroalgae on Mo’orea. Microplastics were discovered in the water column of the fringing reef of the island, at a concentration of 0.74 pieces m−2. Additionally, this study reports for the first time the ingestion of microplastic by the corallimorpha Discosoma nummiforme. Microplastics were made available to corallimorph polyps in a laboratory setting over the course of 108 h. Positively and negatively buoyant microplastics were ingested, and a microplastic particle that was not experimentally introduced was also discovered in the stomach cavity of one organism. This study indicates that plastic pollution has the potential to negatively impact coral reef ecosystems of the South Pacific, and warrants further study to explore the broader potential impacts of plastic pollution on coral reef ecosystems.
