Authors: Czan Andrej , Babík Ondrej , Miklos Matej , Záušková Lucia , Mezencevová Viktória 
Published: February 2018

AbstractSince most of the implant surface is in direct contact with bone tissue, shape and integrity of said surface has great influence on successful osseointegration. Among other characteristics that predetermine titanium of different grades of pureness as ideal biomaterial, titanium shows high mechanical strength making precise miniature machining increasingly difficult. Current titanium-based implants are often anodized due to colour coding. This anodized layer has important functional properties for right usage and also bio-compatibility of dental implants. Physical method of anodizing and usage of anodizing mediums has a significant influence on the surface quality and itself functionality. However, basic requirement of the dental implant with satisfactory properties is quality of machined surface before anodizing. Roughness, for example, is factor affecting of time length of anodizing operation and so whole productivity. The paper is focused on monitoring of surface and area characteristics, such as roughness or surface integrity after different cutting conditions of miniature machining of dental implants and their impact on suitability for creation of satisfactory anodized layer with the correct biocompatible functional properties.
Retailing science: genre hybridization in online science news stories
Authors: Zhang Yiqiong 
Published: February 2018

AbstractThis study explores how marketing and science rhetoric have become entrenched in online science news stories. The schematic structures of a corpus of 270 news stories from three types of website (university websites, the websites of Futurity.org and MSNBC.com) have been analyzed and compared. An eight-move structure identified from the corpus suggests that the genre of news stories is a hybridization of promotional discourse for marketization and science discourse for explanation. Hybridization is first evident in university press releases, which are then spread by the mass media without significant changes. From the perspective of intertextual chains, the emerging discourse practices can be attributed to the power shifting of news production from journalists to science institutions and further from journalistic to scientific norms. In turn, the discourse practices accelerate the shift of power, which could ultimately lead to the loss of independent and critical science journalism.
The Impact of Foreign Direct Investment on the Romanian Labour Market: New Evidence from a Pooled Model
Authors: Diaconu Maxim Laura , Sterbuleac Daniel 
Published: February 2018

Abstract
The present paper presents a series of results concerning the labour market impact of the foreign direct investment (FDI) inflows in Romania, during the period 2005-2014. In order to reach this objective, we have conducted both an investigation of the specialized literature and an econometric analysis, based on a pooled OLS regression. The added value of this study results from the novelty aspects brought by the results, which indicate two new roles of FDI on the Romanian labour market: a potential “gap-widening” effect between the civil employment and number of employees and a “crawling” effect on the net income. Since the results showed a positive correlation between FDI and civil employment and also between FDI and the average number of employees, the first effect suggests that most of employees of the foreign firms work there less than one year. This may explain why foreign companies are not motivated to offer their employees much higher wages than the local firms and thus that the effect of FDI on nominal net income is very small (“crawling” effect).
Financing Human Development for Sectorial Growth: A Time Series Analysis
Authors: Shobande Abdul Olatunji , Etukomeni Charles 
Published: February 2018

Abstract
The role which financing human development plays in fostering the sectorial growth of an economy cannot be undermined. It is a key instrument which can be utilized to alleviate poverty, create employment and ensure the sustenance of economic growth and development. Thus financing human development for sectorial growth has taken the center stage of economic growth and development strategies in most countries. In a constructive effort to examine the in-depth relationship between the variables in the Nigerian space, this paper provides evidence on the impact of financing human development and sectorial growth in Nigeria between 1982 and 2016, using the Johansen co-integration techniques to test for co-integration among the variables and the Vector Error Correction Model (VECM) to ascertain the speed of adjustment of the variables to their long run equilibrium position. The analysis shows that a long and short run relationship exists between financing human capital development and sectorial growth during the period reviewed. Therefore, the paper argues that for an active foundation for sustainable sectorial growth and development, financing human capital development across each unit is urgently required through increased budgetary allocation for both health and educational sectors since they are key components of human capital development in a nation.

Published: February 2018

Abstract
For a long time it has been a well-known and proven fact that economic growth of a country contributes to improvement of the health status of population. There is at the same time another type of opposite relationship starting from health status and pointing to the performance of economy. In our study, besides giving a general presentation of the health situation in Hungary, we examined the direction and strength of the relations between health and economic indicators and the inequalities that can be identified between the different regions with help of statistical methods. Another objective of the study was to examine the factors influencing mortality, and to develop a multiple linear regression equation to estimate the degree of mortality at a confidence interval of 95%. The results could provide a good basis to determine the intervention points necessary to alleviate and improve the economic burden of bad health status and diseases.

Authors: Kolomak I. O. , Kruchynenko O. V. 
Published: February 2018

Abstract
The species composition of pigeon lice parasitic on pigeons of ornamental breeds on the specialized closed-type farm (Poltava) was studied. Five species of these ectoparasites were registered: Columbicola columbae Linnaeus, 1758, Campanulotes compar Burmeister, 1838, (Philopteridae, Ischnocera), Bonomiella columbae Emerson, 1957, Hohorstiella lata Piaget, 1880 and Neocolpocephalus turbinatum (Denny, 1842) (Menoponidae, Amblycera). For each species, the data on infection prevalence, intensity and abundance were obtained. High prevalence of infection was registered for all pigeon lice species, while the intensity and, especially, the abundance were considerably different. C. columbae turned out to be the most abundant. B. columbae was rather common. The peculiarities of pigeon lice species localization on the host body were investigated. During the intensive infection of pigeons with lice, the complex of clinical signs is manifested, which testifies about considerable effect of these parasites on the host. The highest pathogenicity is characteristic for H. lata, which usually feeds on blood and lymph.

Authors: Markova A. O. 
Published: February 2018

Abstract
Study of aggressive behavior of different species of birds in various places of the Wood-and-Steppe Zone of Ukraine with the methods of continuous logging and total surveillance revealed that aggression manifestation of birds in different territories are similar. Ratings of successive interactions among aggressive species in different areas are evaluated. According to the ratings, four types of birds position in the ranking were allocated and the species always holding to them in any area are established. The Blackbird is always dominating, whereas the Blue Tit and Treecreeper occupy a subordinate position. The Nuthatch, Greenfinch, Chaffinch, Marsh Tit, Great Tit, and Blackcap are characterized by active successful attack, but have low defense rating. These results can be used in analyzing the adaptation of certain bird species in communities and their success in competitive interactions in different areas.

Published: February 2018

Abstract
The steady non-isothermal flow of an Eyring–Powell fluid in a pipe is investigated using both perturbation and numerical methods. The results are presented for two viscosity models, namely the Reynolds model and the Vogel model. The shooting method is employed to compute the numerical solution. Criteria for validity of perturbation solution are developed. When these criteria are met, it is shown that the perturbation solution is in good agreement with the numerical solution. The influence of various emerging parameters on the velocity and temperature field is also shown.

Fast and Slow Oscillations Recruit Molecularly-Distinct Subnetworks of Lateral Hypothalamic NeuronsIn Situ
Authors: Kosse Christin , Burdakov Denis 
Published: February 2018

AbstractElectrical signals generated by molecularly-distinct classes of lateral hypothalamus (LH) neurons have distinct physiological consequences. For example, LH orexin neurons promote net body energy expenditure, while LH non-orexin neurons [VGAT, melanin-concentrating hormone (MCH)] drive net energy conservation. Appropriate switching between such physiologically-opposing LH outputs is traditionally thought to require cell-type-specific chemical modulation of LH firing. However, it was recently found that,in vivo,the LH neurons are also physiologically exposed to electrical oscillations of different frequency bands. The role of the different physiological oscillation frequencies in firing of orexin vs non-orexin LH neurons remains unknown. Here, we used brain-slice whole-cell patch-clamp technology to target precisely-defined oscillation waveforms to individual molecularly-defined classes LH cells (orexin, VGAT, MCH, GAD65), while measuring the action potential output of the cells. By modulating the frequency of sinusoidal oscillatory input, we found that high-frequency oscillations (γ, ≈30–200 Hz) preferentially silenced the action potential output orexinLHcells. In contrast, low frequencies (δ-θ, ≈0.5–7 Hz) similarly permitted outputs from different LH cell types. This differential control of orexin and non-orexin cells by oscillation frequency was mediated by cell-specific, impedance-unrelated resonance mechanisms. These results substantiate electrical oscillations as a novel input modality for cell-type-specific control of LH firing, which offers an unforeseen way to control specific cell ensembles within this highly heterogeneous neuronal cluster.
Notational analysis of evasive agility skills executed by attacking ball carriers among elite rugby players of the 2015 Rugby World Cup

Published: February 2018

The role of skill in task execution among elite rugby players has become the focus of numerous researchers. We aimed to analyse the frequency, the most highly utilized and successful as well as unsuccessful attempts of evasive agility skills executed by attacking ball carriers among elite rugby players. The analysis was based on 32 matches played during the 2015 Rugby World Cup matches with the sample being attacking ball carriers among the Top 3 and Bottom 3 Elite Rugby Teams. It was shown that attacking ball carriers among the Top 3 displayed a 59% (straight), 39% (side-step) and 2% (crossover-step) while the Bottom 3 exhibited a 45% (straight), 52% (side-step) and 3% (crossover-step) of these movement patterns. Alternatively, the independent sample t-test revealed that there was no significant difference in the frequency of the execution of the side-step and crossover-step (p>0.05) between the two team categories while a significant difference was observed for these teams for the straight evasive agility skill (p=0.012). The straight evasive agility skill was the most frequently executed and highly utilized by the Top 3 though portraying a high rate of being unsuccessful (29% successful rate).Conversely, the side-step evasive movement pattern was the most frequently executed and highly utilized by the Bottom 3 (21% successful rate).These results suggest that the successful rate of the evasive agility skills executed may not be the determining factor among elite rugby players and the reasons underlying this observation may need further clarification.
RNA-Interference Pathways Display High Rates of Adaptive Protein Evolution in Multiple Invertebrates
Authors: Palmer William H , Hadfield Jarrod D , Obbard Darren J 
Published: February 2018

Abstract
Conflict between organisms can lead to a reciprocal adaptation that manifests as an increased evolutionary rate in genes mediating the conflict. This adaptive signature has been observed in RNA-interference (RNAi) pathway genes involved in the suppression of viruses and transposable elements in Drosophila melanogaster, suggesting that a subset of Drosophila RNAi genes may be locked in an arms race with these parasites. However, it is not known whether rapid evolution of RNAi genes is a general phenomenon across invertebrates, or which RNAi genes generally evolve adaptively. Here we use population genomic data from eight invertebrate species to infer rates of adaptive sequence evolution, and to test for past and ongoing selective sweeps in RNAi genes. We assess rates of adaptive protein evolution across species using a formal meta-analytic framework to combine data across species and by implementing a multispecies generalized linear mixed model of mutation counts. Across species, we find that RNAi genes display a greater rate of adaptive protein substitution than other genes, and that this is primarily mediated by positive selection acting on the genes most likely to defend against viruses and transposable elements. In contrast, evidence for recent selective sweeps is broadly spread across functional classes of RNAi genes and differs substantially among species. Finally, we identify genes that exhibit elevated adaptive evolution across the analyzed insect species, perhaps due to concurrent parasite-mediated arms races.

OBJECTIVES:
To identify associations between use of ipratropium and/or intravenous magnesium and outcomes of children hospitalized with acute asthma exacerbations and treated with continuous albuterol.

METHODS:
Secondary analysis of data from children prospectively enrolled in the multicenter Ohio Pediatric Asthma Repository restricted to only children who were treated with continuous albuterol in their initial inpatient location. Children were treated with adjunctive therapies per the clinical team.

RESULTS:
Among 242 children who received continuous albuterol, 94 (39%) received ipratropium only, 13 (5%) received magnesium alone, 42 (17%) received both, and 93 (38%) received neither. The median duration of continuous albuterol was 7.0 (interquartile range [IQR]: 2.8–12.0) hours. Ipratropium use was associated with a shorter duration of continuous albuterol (4.9 [IQR: 2.0–10.0] hours) compared with dual therapy (11.0 [IQR: 5.6–28.6] hours; P = .001), but magnesium use was not (7.5 [IQR: 2.5–16.0] hours; P = .542). In Cox proportional models (adjusted for hospital, demographics, treatment location, and respiratory failure), magnesium was associated with longer durations of continuous albuterol (hazard ratio, 0.54 [95% confidence interval: 0.37–0.77]; P &lt; .001) and hospitalization (hazard ratio, 0.41 [95% confidence interval: 0.28–0.60]; P &lt; .001), but ipratropium was not.

CONCLUSIONS:
Ipratropium and magnesium were both often used in children with severe asthma hospitalizations that required continuous albuterol therapy. Magnesium use was associated with unfavorable outcomes, possibly reflecting preferential treatment to patients with more severe cases and differing practices between centers. Given the high prevalence of asthma, wide variations in practice, and the potential to improve outcomes and costs, prospective trials of these adjunctive therapies are needed.
