Sedimentary-vegetation response to the channel by-pass: A case study of the Danube river
Authors: Horáčková Šárka , Lehotský Milan , Štefanička Tomáš , Viczián István 
Published: June 2017

Abstract
The Gabčíkovo-Nagymaros waterworks construction on Danube river in Slovakia (1977−1992) was followed with major ecological consequences. The water level and flow velocity was decreased in the original by-passed channel in order to keep high water level for shipping in the bypass canal. The decrease in discharge and lowering flow velocity resulted in the channel narrowing and increase in the vertical accretion magnitude in new floodplain pockets along both sides of by-passed channel. What is more, anthropic intervention in form of groynes structures built for channel adjustment before 1992 dramatically accelerated this process. Vegetation colonisation took place on the new floodplain. In this paper, we analysed land cover changes - vegetation succession using aerial photographs taken in 1986, 1996, 2004 and 2013 as well as field surveys. After the flood in 2013, the area of the new floodplain reached 57% (310 ha) of the original channel area.

AbstractThe purpose of this study was to investigate whether a tethered-swimming incremental test comprising small increases in resistive force applied every 60 seconds could delineate the isocapnic region during rapidly-incremented exercise. Sixteen competitive swimmers (male, n = 11; female, n = 5) performed: (a) a test to determine highest force during 30 seconds of all-out tethered swimming (Favg) and the ΔF, which represented the difference between Favgand the force required to maintain body alignment (Fbase), and (b) an incremental test beginning with 60 seconds of tethered swimming against a load that exceeded Fbaseby 30% of ΔF followed by increments of 5% of ΔF every 60 seconds. This incremental test was continued until the limit of tolerance with pulmonary gas exchange (rates of oxygen uptake and carbon dioxide production) and ventilatory (rate of minute ventilation) data collected breath by breath. These data were subsequently analyzed to determine whether two breakpoints defining the isocapnic region (i.e., gas exchange threshold and respiratory compensation point) were present. We also determined the peak rate of O2uptake and exercise economy during the incremental test. The gas exchange threshold and respiratory compensation point were observed for each test such that the associated metabolic rates, which bound the heavy-intensity domain during constant-work-rate exercise, could be determined. Significant correlations (Spearman’s) were observed for exercise economy along with (a) peak rate of oxygen uptake (ρ = .562; p < 0.025), and (b) metabolic rate at gas exchange threshold (ρ = −.759; p < 0.005). A rapidly-incremented tethered-swimming test allows for determination of the metabolic rates that define zones for domain-specific constant-work-rate training.

Published: June 2017

Abstract
Recently there has been a noticeable trend of rising awareness among the employers in Poland of the fact that training on occupational health and safety may to the quality and effectiveness of their business. Providing safe employment is beneficial to both the employer and the employee. Work safety has an influence among others on efficiency, which is in turn one of the fundamental factors affecting the profitability of business activity, especially at the time of crisis. Work safety is important not only at micro but also macroeconomic level as lack of accidents affects the reduction of job costs, the state spends less on accident allowances or rehabilitation benefits. In the traditional approach to training focus was placed only on the training content regardless of the assessment of its effectiveness, and particularly the quality of training measured as the assessment given by the trainee. This study presents a proposition of a new approach consisting in reviewing traditional training on occupational health and safety. This approach aims at improving the quality of training through an appropriately developed training system with the use of e-learning.

Abstract
The purpose of this study was to evaluate the differences in the disposition and plasma pharmacokinetic behavior of marbofloxacin (MAR) in broiler chickens at different seasons. Chicken broilers (n = 345) were used, in lots of 5 individuals, divided into 6 groups depending on the way of administration, intravenous or oral (dose 2 mg/kg) and the test period. Post-administration plasma samples were obtained at different times, intravenously (0.08 to 24 hours) and orally (0.25 to 120 hours). A liquid-liquid extraction of MAR was performed by high-performance liquid chromatography (HPLC) with a fluorescent detector. The plasma concentrations obtained at the different sampling times of each season, were analyzed with ANOVA and pharmacokinetic analysis was conducted with the PK Solution 2.0 software. The concentration of marbofloxacin in plasma was significantly lower in winter and summer than in spring, with MAR being detected in winter up to 72 hours post-application, coinciding with the differences in MAR pharmacokinetics parameters with increase in the average residence time (MRT) is 9.4 hours in winter. Increased clearance MAR in summer (7.5 ml/min/kg) coincides with MRT 6.3 hours. Finally, the oral bioavailability of MAR is lower in summer and winter (86 ± 1.7% and 78 ± 3.1%) than in spring (94 ± 5.2 %). There are differences in the disposition and plasma pharmacokinetic behavior of MAR applied orally in broiler chickens, coinciding with the physiological changes in the thermoregulation of birds, considering its correct therapeutic management and contributing to provide safe food for human consumption.

A second order numerical method for a class of parameterized singular perturbation problems on adaptive grid
Authors: Shakti D. , Mohapatra J. 
Published: June 2017

AbstractA nonlinear singularly perturbed boundary value problem depending on a parameter is considered. First, we solve the problem using the backward Euler finite difference scheme on an adaptive grid. The adaptive grid is a special nonuniform mesh generated through equidistribution principle by a positive monitor function depending on the solution. The behavior of the solution, the stability and the error estimates are discussed. Then, the Richardson extrapolation technique is applied to improve the accuracy of the computed solution associated to the backward Euler scheme. The proofs of the uniform convergence for the backward Euler scheme and the Richardson extrapolation are carried out. Numerical experiments validate the theoretical estimates and indicates that the estimates are sharp.
Vowel reduction patterns of early Spanish- English bilinguals receiving continuous L1 and L2 input
Authors: Byers Emily 
Published: June 2017

AbstractThis study investigates the production of three morphophonetic variations of schwa in American English: the plural allomorph {-s} as in watches, the possessive allomorph {-s} as in Sasha’s, and word-finally as in Russia. The production of these three allomorphs were examined in Miami’s English monolingual and early Spanish-English bilingual populations. Our purpose was to determine how native-like early Spanish-English bilinguals′ spectral qualities and reduced vowel durations were compared to Miami English monolinguals during a reading task. Results indicate that early bilinguals′ reduced vowels followed the same overall pattern as monolinguals, but had different acoustic properties.
Comparative Genomics of Two Sequential Candida glabrata Clinical Isolates

Published: June 2017

Abstract
Candida glabrata is an important fungal pathogen which develops rapid antifungal resistance in treated patients. It is known that azole treatments lead to antifungal resistance in this fungal species and that multidrug efflux transporters are involved in this process. Specific mutations in the transcriptional regulator PDR1 result in upregulation of the transporters. In addition, we showed that the PDR1 mutations can contribute to enhance virulence in animal models. In this study, we were interested to compare genomes of two specific C. glabrata-related isolates, one of which was azole susceptible (DSY562) while the other was azole resistant (DSY565). DSY565 contained a PDR1 mutation (L280F) and was isolated after a time-lapse of 50 d of azole therapy. We expected that genome comparisons between both isolates could reveal additional mutations reflecting host adaptation or even additional resistance mechanisms. The PacBio technology used here yielded 14 major contigs (sizes 0.18–1.6 Mb) and mitochondrial genomes from both DSY562 and DSY565 isolates that were highly similar to each other. Comparisons of the clinical genomes with the published CBS138 genome indicated important genome rearrangements, but not between the clinical strains. Among the unique features, several retrotransposons were identified in the genomes of the investigated clinical isolates. DSY562 and DSY565 each contained a large set of adhesin-like genes (101 and 107, respectively), which exceed by far the number of reported adhesins (63) in the CBS138 genome. Comparison between DSY562 and DSY565 yielded 17 nonsynonymous SNPs (among which the was the expected PDR1 mutation) as well as small size indels in coding regions (11) but mainly in adhesin-like genes. The genomes contained a DNA mismatch repair allele of MSH2 known to be involved in the so-called hyper-mutator phenotype of this yeast species and the number of accumulated mutations between both clinical isolates is consistent with the presence of a MSH2 defect. In conclusion, this study is the first to compare genomes of C. glabrata sequential clinical isolates using the PacBio technology as an approach. The genomes of these isolates taken in the same patient at two different time points exhibited limited variations, even if submitted to the host pressure.

AbstractDomesticated carrots, Daucus carota subsp. sativus, are the richest source of β-carotene in the US diet, which, when consumed, is converted into vitamin A, an essential component of eye health and immunity. The Y2 locus plays a significant role in beta-carotene accumulation in carrot roots, but a candidate gene has not been identified. To advance our understanding of this locus, the genetic basis of β-carotene accumulation was explored by utilizing an advanced mapping population, transcriptome analysis, and nucleotide diversity in diverse carrot accessions with varying levels of β-carotene. A single large effect Quantitative Trait Locus (QTL) on the distal arm of chromosome 7 overlapped with the previously identified β-carotene accumulation QTL, Y2. Fine mapping efforts reduced the genomic region of interest to 650 kb including 72 genes. Transcriptome analysis within this fine mapped region identified four genes differentially expressed at two developmental time points, and 13 genes differentially expressed at one time point. These differentially expressed genes included transcription factors and genes involved in light signaling and carotenoid flux, including a member of the Di19 gene family involved in Arabidopsis photomorphogenesis, and a homolog of the bHLH36 transcription factor involved in maize carotenoid metabolism. Analysis of nucleotide diversity in 25 resequenced carrot accessions revealed a drastic decrease in diversity of this fine-mapped region in orange cultivated accessions as compared to white and yellow cultivated and to white wild samples. The results presented in this study provide a foundation to identify and characterize the gene underlying β-carotene accumulation in carrot.

Aim. Treatment of patients with multiple congenital anomalies of the spine is a complex problem, demanding both correction and stabilization to be performed as early as possible without disturbing the growth of the spinal column. To achieve the latter, different instrumentation, such as rib-based distractors, may be useful. Little is known this treatment of congenital spine deformities. We aimed to investigate the results of treatment in our patients with the use of out-of-spine-based metal implants.
Material and methods. During 2012–2016, there were 44 procedures performed in 20 patients at an age of 2 years to 12 years. In 13 cases, the deformity was located in the thoracic spine and in the thoracolumbar regions in 7 cases. We used bifocal rib-rib connections in 18 procedures, and a rib-spine connection in 26 cases. Results were evaluated based upon the amount of achieved correction after each procedure, amount of stages of treatment, and complication rates.
Results. The mean curve magnitude was 68.7°. The mount of staged procedures varied from 3 to 7. The mean amount of achieved correction was 15.1°. In all cases, deformity was lower than at the beginning of the treatment. The complication rate was 15.9%.
Conclusion. We assume that out-of-spine-based metal implants may be used in treatment of patients with multiple congenital spine and thorax anomalies, as this technique allows effective correction and stabilization of the deformity, as well as increases the volume of the hemithorax.

La depresión es el trastorno mental más frecuente a nivel mundial y nacional. Sin embargo, en servicios de atención primaria, solo 50 a 70% de pacientes con este cuadro son apropiadamente diagnosticados. Objetivos: Identificar el nivel de conocimientos, actitudes y prácticas sobre depresión mayor en médicos residentes de un hospital general en Lima, Perú, evaluados durante un periodo de 30 días. Material y métodos: Estudio descriptivo, correlacional, de corte transversal. Se encuestó a médicos residentes de todos los años y de diferentes especialidades. Resultados: De un total de 113 residentes (56,64% varones), solo el 5,31% había recibido durante el residentado un curso de psiquiatría y salud mental. El 15,93% demostró conocimiento insuficiente, 73,45% conocimiento moderado, y 10,62% conocimiento suficiente sobre depresión. No hubo asociación estadísticamente significativa entre el puntaje total de conocimiento y confianza en su capacidad para diagnosticar depresión. Aunque el 88,5% consideró que la depresión es una enfermedad, solo el 55,75% del grupo encuestado opinó que todos los médicos deben ser capaces de detectar e iniciar tratamiento de un caso de depresión. Conclusiones: El conocimiento sobre depresión, entre los médicos residentes evaluados en este estudio dista de ser óptimo. Un porcentaje pequeño pero significativo de los participantes mostró persistentes actitudes negativas hacia la valoración de la depresión como enfermedad mental y menos de la mitad están correctamente informados acerca de aspectos relevantes del tratamiento. La necesidad de corregir estas deficiencias es perentoria.

Published: June 2017

Nitrous oxide (N2O) is a greenhouse gas (GHG) emitted from agricultural operations. The objective of this research was to quantify N2O‐N emissions from simulated open‐lot beef cattle feedlot pens after rainfall. A recirculating‐flow‐through, non‐steady state chamber system consisting of five 1‐m2 steel pans was designed for quantifying emissions. A lid was placed sequentially on each pan, and headspace air was recirculated between the pan and a real‐time N2O analyzer, measuring concentrations every 1 s. Air‐dried manure (89.2% dry matter) from a commercial feedlot in the Texas Panhandle was placed in the pans and then 0, 6.3, 12.7, 25.4, or 50.8 mm of water was applied to simulate a one‐time rainfall event. Emissions of N2O‐N were monitored for 45 d, where two distinct episodes of N2O‐N production were observed over time. The first N2O‐N episode had a duration of 10 h and peaked 2 h after rainfall at a flux of 1.0 to 200 mg m−2 h−1. The second episode had a duration of 40 d and peaked 15 d after rainfall at a flux of 0.06 to 35 mg m−2 h−1. The second episode accounted for 69 to 91% of the cumulative N2O‐N emitted over the 45‐d period. Each millimeter of rainfall increased cumulative N2O‐N emitted by 167.9 mg m−2 (r2 = 0.99, P < 0.001). This rainfall vs. cumulative emissions relationship will be useful for modeling annual N2O‐N emissions from open‐lot beef cattle feedlots, and for assessing the effectiveness of best management practices for reducing feedlot GHG emissions.Core Ideas
A rapid (60 s) method was developed to quantify fluxes of N2O‐N from manure.
In a 45‐d period, there were two distinct N2O‐N episodes after simulated rainfall.
The first N2O‐N episode peaked 2 h after rainfall, the second 15 d later.
The second accounted for ∼80% of total N2O‐N emitted during the 45‐d period.
Each millimeter of rainfall increased N2O‐N emissions by 168 mg m−2 over 45 d.

Published: June 2017

In the big data background, the accuracy of fault diagnosis and recognition has been difficult to be improved. The deep neural network was used to recognize the diagnosis rate of the bearing with four kinds of conditions and compared with traditional BP neural network, genetic neural network and particle swarm neural network. Results showed that the diagnosis accuracy and convergence rate of the deep neural network were obviously higher than those of other models. Fault diagnosis rates with different sample sizes and training sample proportions were then studied to compare with the latest reported methods. Results showed that fault diagnosis had a good stability using deep neural networks. Vibration accelerations of the bearing with different fault diameters and excitation loads were extracted. The deep neural network was used to recognize these faults. Diagnosis accuracy was very high. In particular, the fault diagnosis rate was 98 % when signal features of vibration accelerations were very obvious, which indicated that using deep neural network was effective in diagnosing and recognizing different types of faults. Finally, the deep neural network was used to conduct fault diagnosis for the gearbox of wind turbines and compared with the other models to present that it would work well in the industrial environment.
