The Court of the Eurasian Economic Union: Challenges of Functioning
Authors: Baishev Zholymbet
Published: June 2019

The Court of Eurasian Economic Union is envisaged by the Treaty on EAEC (Eurasian Economic Community) as one of the bodies of the Union. Its principal aim is to ensure uniform application of the Treaty and compliance of the agreements adopted by the Union member states as well as acts of the Union bodies with the Treaty.All member states, bodies of the Union and, in certain cases, economic entities has the right of appeal to the Court. The Court is empowered to adjudicate cases of disputes arisen within the framework of the Union as well as to issue advisory opinions. Court decisions are binding while advisory opinions are of suggestive nature. When hearing cases, the Court applies the Treaty on EAEC, international treaties of the states concluded within the framework of the Union and norms of international law.Established in 2015, the Court of EAEC appeared to be in demand among the states, economic entities and bodies of EAEC. The analysis of the activities of the Court and its legal framework enabled to identify a number of outstanding issues related to the status and organization of the activities of the Court. Thus, the competence of the Court as stipulated by the Statute does not reflect the power (as stipulated by the Treaty) of the Highest Eurasian Economic Union to appeal to the Court with a request. The limits of competence of the Court are not clearly and sufficiently denoted, the fact that might serve grounds for the unwarranted expansion thereof. The procedure for initiation of issuance of advisory opinions and termination of proceedings in such cases is not sufficiently regulated. There is no clarity as to the legitimacy of the collective dissenting opinions of judges.The analysis of the Court practice shows that in broad terms it fulfills its mandate. The decisions adopted by it enabled to elaborate critical legal positions and clarify many practical issues in such areas as functioning of the Customs Union and internal market of the Union, general principles and rules of competition, protective measures for internal market and transportation policy.

Interactions of Atomic and Molecular Hydrogen with a Diamond-like Carbon Surface: H2 Formation and Desorption
Authors: Tsuge Masashi , Hama Tetsuya , Kimura Yuki , Kouchi Akira , Watanabe Naoki
Published: June 2019

The interactions of atomic and molecular hydrogen with bare interstellar dust grain surfaces are important for understanding H2 formation at relatively high temperatures (>20 K). We investigate the diffusion of physisorbed H atoms and the desorption energetics of H2 molecules on an amorphous diamond-like carbon (DLC) surface. From temperature-programmed desorption experiments with a resonance-enhanced multiphoton ionization (REMPI) method for H2 detection, the H2 coverage-dependent activation energies for H2 desorption are determined. The activation energies decrease with increasing H2 coverage and are centered at 30 meV with a narrow distribution. Using a combination of photostimulated desorption and REMPI methods, the time variations of the surface number density of H2 following atomic and molecular hydrogen depositions are studied. From these measurements, we show that H2 formation on a DLC surface is quite efficient, even at 20 K. A significant kinetic isotope effect for H2 and D2 recombination reactions suggests that H-atom diffusion on a DLC surface is mediated by quantum mechanical tunneling. In astrophysically relevant conditions, H2 recombination due to physisorbed H-atoms is unlikely to occur at 20 K, suggesting that chemisorbed H atoms might play a role in H2 formation at relatively high temperatures.
The Vertical Motion History of Disk Stars throughout the Galaxy
Authors: Ting 丁 Yuan-Sen 源森 , Rix Hans-Walter
Published: June 2019

It has long been known that the vertical motions of Galactic disk stars increase with stellar age, commonly interpreted as vertical heating through orbit scattering. Here we map the vertical actions of disk stars as a function of age (

as a combination of the vertical action at birth,

relation at all radii is considerably steeper (

We illustrate how this conundrum can be resolved if we also account for the fact that at earlier epochs, the scatterers were more common, and the restoring force from the stellar disk surface mass density was low. Our analysis may reinstate gradual orbital scattering as a plausible and viable mechanism to explain the age-dependent vertical motions of disk stars.
Modeling the X-Ray Power Spectra of AGN by Using Reprocessing Echoes from an Extended Corona
Authors: Chainakun P.
Published: June 2019

Characteristic signatures that X-ray reverberation from an extended corona can manifest in the observed PSD of AGN are investigated. The presence of two X-ray blobs illuminating an accretion disk can cause the interference between two reprocessing-echo components and produce distinct physical features in the PSD. The oscillatory structures (e.g., dips and humps) are seen, but, contrarily to the lamp-post case, the strongest dip is not always the one at the lowest frequency. Instead, we find that the frequency where the strongest dip is seen is associated with the lower-source height while the lowest frequency where the first dip appears is linked to the upper-source height. This is because the reverberation timescales increase with the source height. Accurate modeling of the PSD then helps put constraints on the lower and upper limits of the corona extent. Furthermore, the reverberation signatures are less pronounced with increasing number of sources that do not produce reflection (e.g., additional X-rays from fast, relativistic outflows). The amplitude of the oscillations also depends on the amount of dilution contributed by the X-ray sources, and thus encodes information about their relative brightness. Due to stronger dilutions, robust detection of these signatures with current observations will become even more difficult if the corona is extended. Future observations made by Athena will enable us to fit these characteristics with statistically significant details, and to reveal the nature of the disk–corona system.

Gut microbiome development affects infant health and postnatal physiology. The gut microbe assemblages of preterm infants have been reported to be different from that of healthy term infants. However, the patterns of ecosystem development and inter-individual differences remain poorly understood. We investigated hospitalised preterm infant gut microbiota development using 16S rRNA gene amplicons and the metabolic profiles of 268 stool samples obtained from 17 intensive care and 42 term infants to elucidate the dynamics and equilibria of the developing microbiota. Infant gut microbiota were predominated by Gram-positive cocci, Enterobacteriaceae or Bifidobacteriaceae, which showed sequential transitions to Bifidobacteriaceae-dominated microbiota. In neonatal intensive care unit preterm infants (NICU preterm infants), Staphylococcaceae abundance was higher immediately after birth than in healthy term infants, and Bifidobacteriaceae colonisation tended to be delayed. No specific NICU-cared infant enterotype-like cluster was observed, suggesting that the constrained environment only affected the pace of transition, but not infant gut microbiota equilibrium. Moreover, infants with Bifidobacteriaceae-dominated microbiota showed higher acetate concentrations and lower pH, which have been associated with host health. Our data provides an in-depth understanding of gut microbiota development in NICU preterm infants and complements earlier studies. Understanding the patterns and inter-individual differences of the preterm infant gut ecosystem is the first step towards controlling the risk of diseases in premature infants by targeting intestinal microbiota.
Analysis of the stress state at the double-step joint in heavy timber structures
Authors: Villar-García J. R. , Vidal-López P. , Crespo J. , Guaita M.
Published: June 2019

The double-step joint is among the most frequently used layouts, within carpentry joints, for transmitting higher forces that would allow a single notch. They are especially effective in heavy timber structures. Nowadays, computer-aided manufacturing is being used more often, demanding further progress in its understanding. The conventional design of these joints is conducted by using simplifying assumptions, in particular regarding the shear stress distribution. This is overcome by the use of strength reduction coefficient, which is currently under study. Numerical simulation and experimental tests were carried out with heavy timber cross-sections for rafter to tie-beam truss joint. They were manufactured in glue-laminated timber owing to the large cross-sections tested. Experimental load-strain and load-displacement diagrams were compared with numerical results. This allowed observing the great shear stress concentration produced in the failure by shear crack, which suggests the application of conservative shear strength reduction coefficients.

Published: June 2019

O objetivo deste estudo foi investigar possíveis associações entre a pobreza, suas dimensões e o estresse parental. Essa pesquisa teve caráter quantitativo, delineamento transversal e amostra probabilística, constituída por 433 participantes cadastrados no Cadastro Único do Governo Federal. Foram aplicados o Inventário Sociodemográfico, o Índice de Pobreza Familiar (IPF) e o Índice de Estresse Parental (PSI). Para relacionar as variáveis dividiram-se os participantes em dois grupos a partir dos instrumentos de pobreza (mais e menos pobres) e estresse (estresse normal e alto). Foram encontradas associações fortemente significativas entre as categorias 'mais pobres' e 'estresse alto', tanto na pobreza multidimensional como em algumas de suas dimensões (acesso a conhecimento, renda e desenvolvimento infantil). Os resultados relacionaram maiores dificuldades nas atividades parentais a aspectos de vulnerabilidade tradicionalmente identificados em estudos de famílias pobres, como renda e conhecimento, e ainda, apontam para as mazelas trazidas pela pobreza às crianças e aos adolescentes.
GÊNERO, SEXUALIDADE E O SEXUAL: O SUJEITO ENTRE BUTLER, FOUCAULT E LAPLANCHE
Authors: Lima Vinícius Moreira , Belo Fábio Roberto Rodrigues
Published: June 2019

Neste trabalho, articulamos um debate crítico entre Butler, Foucault e Laplanche para pensar a constituição do sujeito a partir das categorias centrais utilizadas por esses pensadores: o gênero, a sexualidade e o sexual. Primeiro, desenvolvemos a ideia de jogos libidinais de poder: os jogos de poder foucaultianos não se sustentam sem um suporte libidinal subjetivo. Em seguida, após introduzir as leiturasde Butler e Laplanche, tentamos abrir caminho para uma releitura laplancheana sobre um mal-estar na teoria butleriana da performatividade de gênero. Para isso, aproximamos a performatividade, como repetição citacional de uma norma sem fundamento ontológico, aos conceitos laplancheanos de código tradutivos e mensagens enigmáticas. Como pano de fundo do debate, concebemos que a verdade recalcada dos arranjos normativos de gênero é o sexual, que desafia as tentativas de cristalizar, de forma clara e distinta, o binário tradicional homem-mulher. Do ponto de vista da constituição do sujeito, concluímos apontando a possibilidade de pensar em tratamentos menos mortíferos e menos rígidos para opulsional.

Published: June 2019

Recycling is one of the important approaches to manage the waste effectively. Nowadays, many recycle bins were placed in school, university, shopping complex and housing area. Although most of them have good awareness to support these activities, yet there are still who abuse the usage of recycling bin by inserting prohibited items. To cater such an issue, a Reverse Vending Machine (RVM) with material identification module is proposed to accept only empty recycle items and reject the rest. The constructed system consists of rotating mechanism and collection of sensors to detect empty PET bottle and aluminum can respectively. From the experiment, it can be shown that the module capable to reject unwanted material with an average of 82.5% of accuracy. Such capability shows a promising outcome for preventing the abuse of recycling bins, and can be used to realize the RVM concept by introducing a reward to the person who recycle properly.

Published: June 2019

In this paper, we propose a routing approach in wireless sensor network by taking into consideration the connectivity maintenance between sensor nodes. Each node is being assigned a calculated weight according to its remaining energy rate. If the transmitting node receives an update package from a node participated in the routing during the routing process, it re-examines its routing way choice by comparing the weight of the updated routing way with the weight of the routing ways in its routing table. An example analysis and simulation shows that the proposed approach is effective.

Heat and Mass Transfer of MHD Dissipative Casson Nanofluid Flow over a Stretching or Shrinking Sheet with Multiple Slip Boundary Conditions
Authors: Titiloye Emmanuel O. , Gbadeyan Jacob A. , Adeosun A.T.
Published: June 2019

The present study concerns steady two-dimensional laminar mixed convective boundary layer Casson nanofluid flow along a stretching or shrinking sheet with multiple slip boundary conditions in a non-Darcian porous medium. The effect of viscous dissipation and non-linear radiation are considered. The governing partial differential equations, together with boundary conditions are transformed into a system of dimensionless coupled ordinary differential equations. Galerkin weighted residual method is then employed to solve the transformed coupled ordinary differential equations. The effect of various controlling parameters on dimensionless velocity, temperature, nanoparticle volume fraction, velocity gradient, temperature gradient and nanoparticle volume fraction gradient are presented graphically and discussed. The present approach is validated by comparing the result of this work and those available in the literature, and they are found to be in excellent agreement.

Published: June 2019

Study reveals the axisymmetric squeezing flow of nanofluids through two parallel plates. Both Copper (Cu) and Silver (Ag) nanoparticles along with water treated as base fluid have been taken into consideration. Viscous dissipation effect and velocity slip both enhance the present study. The non-dimensional form of governing nonlinear ODEs is obtained with the suitable choice of similarity transformation. The complex ODEs are solved analytically imposing Adomain Decomposition Method (ADM). The influence of emerging parameters such as nanoparticle volume fraction, unsteadiness parameter, Eckert number, etc. have been described by visualizing graphically and the tabular values represent the unknown coefficient and computation is made for various values of physical parameters. The present result is compatible with the earlier which confirms the accuracy of the solution procedure. It reveals that point of inflection is marked in the velocity profiles of both Ag and Cu water nanofluids for the effects of various physical parameters. Squeezing number play a vital role in the velocity profile and it is observed that near the lower plate Ag nanoparticle dominates over Cu nanoparticles and further, after the middle of the channel the effect is reversed. 2010 Mathematics Subject Classification: 76D05, 76D10, 76M60, 76S05. *Corresponding Author’s Email: HYPERLINK "mailto:satyaranjan_mshr@yahoo.co.in" satyaranjan_mshr@yahoo.co.in Mobile No.: (+91)-9937169245

Magnetohydrodynamics (MHD) boundary layer slip Casson fluid flow over a dissipated moving cylinder is explored. Casson fluid model is employed as a non-Newtonian material that demonstrates the phenomenon of yield stress. Blood material is considered to be an example of Casson liquid. The non-linear partial differential quantities are transformed into expressions of ordinary derivatives through transformation of similarity variables. These equations are computed for numeric solutions by using Runge-Kutta method along with shooting scheme. The impact of pertinent constraints on the fluid velocity and temperature are examined through graphs. The coefficient of the skin friction and the rate of heat transfer are found numerically. Comparing of the present study with the earlier results is also presented. We observed that the coefficient of skin friction increases for higher values of Hartmann number.

Effect of Boundary Layer and Rotor Speed
on Broadband Noise from Wind Turbines
Authors: Bhargava Vasishta , Samala Rahul
Published: June 2019

Trailing edge surface of aerofoil is an important source of broadband aerodynamic noise production. In this paper, three aerofoil self-noise mechanisms from turbulent boundary layer near trailing edge surface are studied. Numerical computations were performed for a three bladed 2 MW horizontal axis upwind turbine of blade length 37 m and source height of 80 m, for wind speeds of 8-15 m/s. A weighted 1/3rd octave band sound power levels (SPL) are evaluated for receiver located at distance of total turbine height and at 2 m above ground. The results obtained for sound power level using baseline models showed maximum values occurring between 300 Hz and 1 kHz region of spectrum. The trends for BPM model showed a reduction of ~2 dBA near 1 kHz region of spectrum at 10 m/s, but Grosveld’s and Lowson model were identical and agreed over the entire spectrum. The effect of rotational speed on sound power levels using three baseline models are illustrated at a wind speed of 8 m/s for 2 MW turbine. Results showed that for a change of ±10% rotor speed from the rated value, there is an increase of 2 to 6 dBA over the entire sound spectrum due to differences in blade tip speed.

Aprendices explotados: Precarización del trabajo periodístico a través de una lógica abusiva de becas y prácticas
Authors: García de Madariaga1 José María , Arasanz Esteban Ignacio
Published: June 2019

La crisis económica iniciada en 2008 y la falta de una regulación adecuada están propiciando que cada vez más estudiantes y becarios vean convertido su aprendizaje en trabajo equiparable al profesional con unas condiciones de sueldo y de derechos muy alejadas de las de una contratación laboral digna. Esta disfunción contribuye de modo muy significativo al proceso de precarización laboral que vive la actividad periodística desde hace décadas, así como al consecuente empobrecimiento de la calidad informativa que ofrecen los medios de comunicación. Este artículo aborda una revisión bibliográfica y legislativa sobre los desequilibrios actuales del mercado laboral periodístico y hace un análisis detallado de su evolución reciente a partir de documentación técnica como la que ofrecen los informes anuales de la profesión periodística de los últimos años elaborados por la Asociación de la Prensa de Madrid.
Falsos autónomos y falsos becarios: una aproximación institucional al caso español
Authors: Sanz de Miguel Pablo
Published: June 2019

El artículo pretende contribuir al debate sobre el empleo irregular en España, a través del análisis de las figuras del falso autónomo y el falso becario. Partiendo de una perspectiva institucional, se estudia la influencia que, sobre estos fraudes laborales, derivados de estrategias empresariales encaminadas a obtener ventajas competitivas, ejercen tres campos: dos estatales asociados, por una parte, al área de la regulación y, por otra, al control del cumplimiento de dicha regulación, concretado en la Inspección de Trabajo y Seguridad Social (ITSS); y un tercero, el de las relaciones laborales, que, en el caso español, depende de manera considerable del estado y la legislación. Para ello se recurre, metodológicamente, a una revisión de la bibliografía y normativa más relevante, y un trabajo de campo basado en entrevistas semi-estructuradas a agentes sociales e inspectores de trabajo y seguridad social. El artículo confirma la relevancia de los tres campos institucionales estudiados, cuya interacción conjunta e interrelacionada contribuye a entender la existencia de estas prácticas. Se identifican también elementos e iniciativas que sugieren que, dentro el marco institucional actual, existe espacio para contribuir a reducir su difusión.

Derivations with invertible values of 0 – torsion flexible algebras satisfying x(yz) = (xz)y over an algebraically closed field are described. For this class of algebra with unit element 1 and derivation with invertible value d is either a Cayley – Dickson algebra over its center Z(A) or a factor algebra of polynomial algebra C[a]/(a2) over a Cayley – Dickson division algebra; also C is 2 – torsion, d(C) = 0 and d(a) = 1+ua for some u in center of C and d is an outer derivation. Moreover, C is a split Cayley – Dickson algebra over its center Z having a derivation with invertible value d if and only if C is obtained by means of Cayley – Dickson process from its associative division subalgebra and can be represented as a direct sum  C = V ⊕ aV.

Ayn Rand's Credit Problem
Authors: Rodgers Lamont
Published: June 2019

In this article, the author diagnoses the cause of Rand's problematic position on intellectual property. He argues that Rand treats credit as a very thick concept. Rand sees crediting a person with inventing something as granting that person a right to the money embodied in the invention, its sale, and the profits related to licensing reproduction. The author shows that this thick notion of credit leads Rand to make several questionable claims in her arguments for intellectual property rights.
Ayn Rand and the Lost Axiom of Aristotle: A Philosophical Mystery—Solved?
Authors: Bissell Roger E.
Published: June 2019

The author explains how Rand was absolutely correct in saying that Aristotle “stated the formula” of the Law of Identity. He corrects long-standing faulty Thomist criticisms on this issue and gives due credit to thinkers such as Antonius Andreas, Leibniz, and William Hamilton. The author further contends that the gradual shift in Objectivist usage of the Law of Identity (from “a thing is itself” to “a thing is what it is”) tacitly ratifies these erroneous criticisms and has actually contributed to the failure of Objectivist thinkers to develop Rand's concept theory into a valid model of propositions and syllogisms.
Honduran Smilax L. (zarzaparrilla) (Liliales, Smilacaceae): an estimate of the amount of plants required for the Boston 1855 exports
Authors: Hazlett Donald L , Ferrufino Lilian
Published: June 2019

The genus Smilax L. has a long history of ethnobotanical uses. Zarzaparrilla was exported from Latin America to Europe for over five centuries to treat syphilis. In 2013, Smilax rhizomes collected from Cortés, Honduras were dried and weighed: one Smilax febrifuga Kunth (cuculmeca blanca), one Smilax officinalis L. (zarzaparrilla), and two individuals of Smilax domingensis Willd. (cuculmeca). The fresh weights of each rhizome were 2.32 kg, 0.52 kg, 0.71 kg, and 24.40 kg, respectively. These values were used to estimate the number of plants needed to meet the 23,405 kg of zarzaparrilla that arrived in Boston in 1855 from Honduras. The weights obtained suggest that to reach the 23,405 kg exported, 10,088 individuals of S. febrifuga would be needed. In the case of S. officinalis, 45,010 would be needed and for S. domingensis, 32,965 young or 959 mature would be necessary. The demand of Smilax (to ineffectively treat syphilis) in combination with deforestation reduced their populations in Honduras. The amount of zarzaparrilla exported from Honduras in 1855 may have been three times the amount that arrived in Boston given that while in Jamaica, ships were unloaded and their zarzaparrilla cargo was subdivided into boats destined for Habana, London, and Boston. A list of Smilax species currently known from Honduras, a review of other ethnobotanical uses, and a discussion of common names for Smilax in the Antilles and Mesoamerica is presented

Published: June 2019

The study analyses the relationship between the growth of the construction industry and economic shocks in Ghana over the 50-year period from 1968 to 2017 using an autoregressive modelling scheme that incorporates several economic shocks as separate independent variables. The independent variables used in the model included one positive economic shock and five negative shock variables. The positive shock variable was the sharply increased government expenditures on construction activities in selected years that allowed the government to host international events in Ghana within a period of two years. The five adverse economic shocks included in the model were political instability related to military coups, exchange rate depreciation of the local currency, Ghana cedi, with respect to the United States dollar, the average yearly temperature, aggregate electricity energy production shortfall related to a severe El Nino weather phenomenon, and incidence of extreme rainfall. The results of the analysis indicated that the most important factor influencing the growth of the construction industry in Ghana over the 50-year study period was political instability. Beyond political instability, the next most important factor was the purposely-driven sharp increases in government expenditures on construction activities for selected years that allowed the country to host international events in the country. The other significant economic shocks were the exchange rate depreciation, average temperatures, and electricity energy production shortfall; all three factors adversely affected the growth of the construction industry. The results of our study are generally consistent with those obtained from the literature concerning the positive and negative effects of economic shocks on the construction industry.
Political Budget Cycles: The Case of Gabon

Published: June 2019

This article analyzes the political-fiscal cycle in Gabon. In Africa, it seems that the analysis of the politico-fiscal cycle has not attracted much interest. This is particularly the case in Gabon, a small country of the Economic and Monetary Community of Central Africa (EMCCA). Unlike approaches based on the estimation of a single model linking the electoral cycle and a dimension of the state budget, we estimate four models each incorporating a different dimension of the state budget, namely: capital expenditures, total expenditures and the budget deficit. The estimation of a VAR Model (2) and three Error Correction Vector Models (ECVM) confirms the existence of an "opportunistic" politico-budgetary cycle in Gabon.

Spraying of dormancy-breaking chemicals is a mandatory procedure to produce temperate fruits in low-chill regions. Although hydrogen cyanamide (HC) + mineral oil (MO) show efficiency enhancing budburst, the usage of HC is restricted in some countries due to its toxicity. Therefore, this research aimed to evaluate the efficiency of spraying different dormancy-breaking agents on ‘Eva’ apple tree buds, under the conditions of the Depressão Central of Rio Grande do Sul, Brazil. Different doses of Erger® (0, 2, 3, 4, 5%) + 3% Ca(NO3)2 were tested and compared with MO (4%) or MO (4%) + HC (0.6%). Budburst rate of apical and axillary buds, physiological alterations in buds, return bloom, yield and fruit weight were evaluated. Erger® treatments efficiently enhanced budburst, with a result equivalent to HC + MO treatment. The budburst rate increased as the Erger® dose increased, also causing the increment of the return bloom in the following year. However, doses of 4 and 5% caused the death of shoots. The activity of the peroxidases and the content of H2O2 in the buds were affected by the treatments. Yield and fruit mass were different in response to treatments, although the effect varied between years. Erger® + Ca(NO3)2 spraying increase budburst in apical and axillary buds of ‘Eva’ apple tree in low-chill conditions and doses up to 3% of the commercial product do not cause toxicity.

The objective of this study was to comparatively analyse the profitability of compost barn and free stall milk-production systems as a means of helping producers and technicians choose the type of facility most suitable for each farm. Data collected from four farms from January to December 2016 were analysed; the data were distributed equally among compost barn and free stall systems. The cost of milk production was estimated according to the operating cost methodology and considering the milk production cost centre, which involved both lactating and dry cows. Additionally, gross and net margins were estimated as indicators of profitability. The results showed that the average gross and net margins were not influenced by the type of facility; they were positive in both of the production systems analysed. Among the components of the net operating cost, the proportion of the "medications" item was lower in the compost barn properties, while the cost of bedding for the cows was lower in the free stall farms. Depreciation and total operating cost were similar in the two systems. Milk sales made up a higher percentage of the revenue in the free stall farms, despite the high standard deviation, while the expectations of revenues from wastes were similar in the two production systems. Given that there were no significant economic differences between the types of facility, it is concluded that ease in management, productivity, reproductive performance, animal health (hoof injuries and mastitis), environmental issues, and availability of water and bedding material should be the motivators for choosing one system over the other.

This study aimed to evaluate the morphogenic, structural, chemical characteristics, and forage yield of Massai grass, as well as the performance of sheep under three pre-grazing canopy heights. Eighteen Dorper x crossbred sheep (12 males and 6 females) were subjected to three pre-grazing canopy heights of Massai grass (45, 35, and 25 cm). Rotational grazing was adopted, with a fixed rest period of 12 days and occupation of four days. Before placing animals in the paddock, stocking rate was estimated to ensure a reduction of about 50% in the initial height. Morphogenic and chemical characteristics of forage were evaluated, as well as animal intake and performance. Pasture managed at 25 cm height induced reductions in stem and sheath sizes, and phyllochron but an increased leaf: stem ratio. However, the pasture cut at 35 cm above ground promoted an increase in total dry mass and foliar leaf productions, in addition to greater forage availability and daily accumulation. Yet, pastures with a height of 45 cm had a higher percentage of stem and senescent material, decreasing leaf intake by animals. Among the studied heights, 35 cm is the most suitable for Massai grass, when used for rearing sheep for meat production under pasture conditions in the northern Tocantins. This is because this management provided a greater availability of good quality forage and thereby increasing weight gains per area in animals.

Published: June 2019

A collection of stomatopods assembled during the KUW 2009 expedition to Mayotte Island and deposited in the Muséum national d’Histoire naturelle Paris is studied with a review of previous records from Comoros and Mayotte Island. In total 14 species are recognized 3 of them being new records for this region. A brief comparison with other regions studied for stomatopods indicates that sampling is still insufficient in Comoros and Mayotte and that dozens of species remain to be inventoried in that region.

Published: June 2019

Invasive species pose one of the most serious global environmental threats. Our study aimed to examine the correlation between the proportion of invasive alien taxa and species diversity of ruderal vegetation in the urban ecosystem of Bratislava, located in Central Europe. Ruderal habitats serve as the means of spread of invasive species to seminatural and natural habitats. Twenty-six invasive taxa were recorded among the ruderal vegetation of Bratislava. The majority of the recorded invasive species were neophytes, which came from North America and represent the Asteraceae family. Half of them were introduced accidentally, whereas the remaining species were introduced deliberately. Correlation and regression analyses showed that the proportion of invasive taxa has a negative effect on the species diversity of all the analyzed syntaxa in the ruderal vegetation of Bratislava.

Objective: The aim of our study was to investigate whether platelet indices were affected in patients with Hashimoto’s thyroiditis (HT). Method: 11 patients (10 female, 1 male) with HT and 26 subjects with nodular goiters (19 female, 7 male) selected as control group were included in the study. All cases were examined for complete blood count parameters (leukocyte count, neutrophil count and percentage, lymphocyte count and percentage, platelet count, plateletcrit, platelet distribution width (PDW), and mean platelet volume (MPV)). Results: Leukocyte count, neutrophil count and percentage, lymphocyte percentage, platelet count, plateletcrit, and MPV in the patient group were not statistically different from the control group. Lymphocyte count and PDW were significantly higher in patients with HT than in the control group. Conclusion: Our results suggest that patients with HT have higher PDW levels. Increased PDW in HT may be helpful in diagnosis, floow-up, and prognosis of the disease.
