Published: February 2018

The target of this study is the Bukuma-minor channel that is distributed along the southern Niger Delta slope. It overlaid the eastern outer levee of the adjacent Bukuma Channel System (BCS) to the north, but it converged westward into BCS to the south. Significant morphological variations between and within these two parts (referred to here as sections A and B) as well as their controlling factors were investigated quantitatively, using high-resolution 3D seismic data: (1) Changes of palaeotopographic gradients were supposed to be the largest contributor to morphological variations in section A (consisting of sections A1 and A2). Section A1 was developed on the low-gradient sector and characterized by the wide and shallow segment, with a relatively sinuous flowpath, whereas section A2, corresponding to a steep slope, was a linearly entrenched one, characterized by the narrow and deep segment. In addition, there were some positive correlations among geometric parameters in section A1, which, however, had been undermined by the large gradient in section A2. (2) Strong confinement of BCS results in the larger width, smaller thickness, and more stable sinuosity of section B. In general, correlations among geometric parameters in this part are not significant. In light of these correlations among geometric parameters and the influence of palaeotopographic gradients, we established an evolutionary model for general submarine channels.

Cowpea (Vigna unguiculata (L.) Walp) is an important legume crop for food security in areas of low-input and smallholder farming throughout Africa and Asia. Genetic improvements are required to increase yield and resilience to biotic and abiotic stress and to enhance cowpea crop performance. An integrated cowpea genomic and gene expression data resource has the potential to greatly accelerate breeding and the delivery of novel genetic traits for cowpea. Extensive genomic resources for cowpea have been absent from the public domain; however, a recent early release reference genome for IT97K-499-35 (Vigna unguiculata v1.0, NSF, UCR, USAID, DOE-JGI, http://phytozome.jgi.doe.gov/) has now been established in a collaboration between the Joint Genome Institute (JGI) and University California (UC) Riverside. Here we release supporting genomic and transcriptomic data for IT97K-499-35 and a second transformable cowpea variety, IT86D-1010. The transcriptome resource includes six tissue-specific datasets for each variety, with particular emphasis on reproductive tissues that extend and support the V. unguiculata v1.0 reference. Annotations have been included in our resource to allow direct mapping to the v1.0 cowpea reference. Access to this resource provided here is supported by raw and assembled data downloads.

Authors: McGroggan Grace , Haughey Sarah , McDowell Karen 
Published: February 2018

Background: Moisture-associated skin damage (MASD) to peristomal skin causes significant discomfort and is expensive to treat. It can be avoided by wicking moisture away from skin and controlling the source of excessive moisture with an absorbent seal. Method: In vitro testing determined the capacity for moisture absorption and combined faecal enzyme (elastase and lipase) inhibition of seven comparable leading UK ostomy seals. Ostomates using Eakin Cohesive® Seals were sent a postal questionnaire to rank the efficacy of this seal, while a different questionnaire was sent to stoma care nurses to rank the relative efficacy of different ostomy seals. Results: Eakin Cohesive Seals had the highest absorption capacity (4.0 g/g), while the range of absorption capacities for other seals was 1.0–2.9 g/g. The enzyme inhibition capacities of Coloplast Brava® Protective Seals and Eakin Cohesive Seals were 94.35% and 72.39% respectively, with other seals ranging from 39.45% to 59.96%. Users (n=2801) found Eakin Cohesive Seals helped prevent leakage (92.5%) and skin problems (73.3%), as well as treating sore skin (68.5%). Of nurses (n=194), 90.2% rated Eakin Cohesive Seal as good or excellent for treating denuded or excoriated skin. Conclusion: Eakin Cohesive Seals were highly absorptive, and this provided tangible clinical benefits.

Published: February 2018

Esta pesquisa tem como objetivo discutir sobre a potência cultural das bibliotecas escolares e universitárias, por conseguinte sobre sua contribuição para a educação estética dos usuários. É uma pesquisa de caráter qualitativo e tem como corpus de análise duas bibliotecas em Itajaí, Santa Catarina, Brasil, sendo uma a Biblioteca Pública Municipal e Escolar Norberto Cândido Silveira Jr. e a outra a Biblioteca Central e Comunitária da Universidade do Vale do Itajaí. Os instrumentos de coleta de dados foram observações registradas em diários de campo, documentos institucionais e fotografias. A análise dos dados pautou-se nos procedimentos da análise de conteúdo, segundo Franco (2008). Os resultados apontam que ambas as bibliotecas se constituem como espaços prioritários de leitura e pesquisa e, mesmo com algumas limitações físicas, elas exploram seus espaços para promover a convivência, a experiência, a cultura e a educação estética. Por meio da análise efetuada, foi possível identificar que os espaços das bibliotecas apontam para a trilogia informar, discutir e criar, revelando sua potência cultural.
Priority Scheduling in the Planning of Multiple-Structure Construction Projects
Authors: Radziszewska-Zielina E. , Sroka B. 
Published: February 2018

AbstractThe paper presents a method of priority scheduling that is useful during the planning of multiple-structure construction projects. This approach is an extension of the concept of interactive scheduling. In priority scheduling, it is the planner that can determine how important each of the technological and organisational constraints are to them. A planner’s preferences can be defined through developing a ranking list that defines which constraints are the most important, and those whose completion can come second. The planner will be able to model the constraints that appear at a construction site more flexibly. The article presents a general linear programming model of the planning of multiple-structure construction projects, as well as various values of each of the parameters that allow us to obtain different planning effects. The proposed model has been implemented in a computer program and its effectiveness has been presented on a calculation example.

Abstract
In this paper, we describe the hardware and software components of a fully autonomous prototype delivery vehicle. Equipped with a robotic arm, the demonstrator is capable of delivering packages and picking up new ones by interacting with custom-made delivery boxes. As highly accurate positioning w. r. t. a box is required for successful handover of packages, we track the pose (position and orientation) of the box using a high-resolution on-board camera. The resulting estimate is relayed to our planning and control modules, which ensure that the vehicle reaches its required pose with centimeter-level accuracy.
In order to deliver packages, the car needs to autonomously navigate our test facility, avoiding static and dynamic obstacles while obeying simple traffic rules. As one focus is on the practical challenges encountered when building a prototype, we cover issues ranging from sensor calibration and system identification to perception, planning, control, and the implementation of high-level behaviors. While some of the proposed solutions to these problems are not necessarily novel, they allowed us to demonstrate the vehicle’s capabilities after a development phase of less than 12 months.

Zusammenfassung
Die Verknüpfung von Automatisierung mit Vernetzung von Fahrzeugen weist in langfristiger Betrachtung eine kaum überschätzbare ökonomische, ökologische und gesellschaftliche Relevanz auf. In der langfristigen Vision wird die vernetzte Automatisierung unseren Straßenverkehr grundlegend verändern. Kooperatives Verhalten zwischen Verkehrsteilnehmern wird dadurch automatisiert erfolgen und somit das Regelverhalten bilden. Außerdem eröffnet technische Kooperation im Vergleich zur heutigen manuellen Kooperation zwischen Verkehrsteilnehmern qualitativ verbesserte und neuartige funktionale Möglichkeiten aufgrund der erzielbaren Latenzzeit, Genauigkeit, Eindeutigkeit und Verlässlichkeit automatischen Verhaltens. Entsprechend aufeinander abgestimmte Trajektorien weisen eine höhere erreichbare Dichte, Geschwindigkeit und Sicherheit auf. Bei langfristig zu erwartendem hohem Durchdringungsgrad des Straßenverkehrs mit vernetzten automatischen Verkehrsteilnehmern sind sichere und hocheffiziente Verkehrsflüsse denkbar, die biologischen Schwarmbewegungen nahe kommen. Dieser Überblicksbeitrag beschreibt den Stand der Forschung in den wesentlichen Forschungsfeldern und das von der DFG eingerichtete Schwerpunktprogramm Kooperativ interagierende Automobile.

AbstractBackground:Screening for antinuclear antibodies by indirect immunofluorescence (ANA-IIF) is essential in the diagnostic workup of ANA-associated autoimmune rheumatic diseases (AARDs). However, also healthy individuals may test positive, making the interpretation challenging. Recent reports suggest that dense fine speckled 70 antibodies (anti-DFS70) may facilitate this challenge. Here, we investigate their clinical importance based on data from four Belgian laboratories (one primary, two secondary and one tertiary care).Methods:At least one specific DFS70 assay (DFS70 IgG ELISA or lineblot [Euroimmun, full length antigen] and/or DFS70 IgG CLIA [Inova Diagnostics, truncated antigen]) was performed on four consecutive cohorts of homogeneous-like ANA-IIF samples (n=697). Co-occurrence with AARD-specific ANA and clinical information were documented in the anti-DFS70-positive samples.Results:Using a combination of solid phase techniques, we found between 7.6% and 26% anti-DFS70 in the different cohorts. Focusing on anti-DFS70 CLIA-positive samples without co-occurrence of AARD-specific ANA, we observed a trend towards lower frequency in tertiary (8% [p=0.0786]) and secondary care (12% [p=0.1275] and 6% [p<0.001]) compared to primary care (21%). Moreover, in this specific subpopulation, AARD was less frequent (0%–50% compared to 6%–77% in the total anti-DFS70-positive group).Conclusions:Anti-DFS70 prevalence depends on the applied assay and care setting. Our data suggest that, for an ANA-IIF-positive patient, it is rather the absence of AARD-associated ANA and clinical symptoms that contribute to the exclusion of AARD than the presence of anti-DFS70. Nevertheless, isolated anti-DFS70 helps to clarify positive ANA-IIF results, especially if pretest probability for AARD is low.
Linking type 2 diabetes and gynecological cancer: an introductory overview

Published: February 2018

AbstractType 2 diabetes (T2D) is a chronic disease with a growing prevalence and a leading cause of death in many countries. Several epidemiological studies observed an association between T2D and increased risk of many types of cancer, such as gynecologic neoplasms (endometrial, cervical, ovarian and vulvar cancer). Insulin resistance, chronic inflammation and high free ovarian steroid hormones are considered the possible mechanisms behind this complex relationship. A higher risk of endometrial cancer was observed in T2D, even though this association largely attenuated after adjusting for obesity. A clear relationship between the incidence of cervical cancer (CC) and T2D has still not be determined; however T2D might have an impact on prognosis in patients with CC. To date, studies on the association between T2D and ovarian cancer (OC) are limited. The effect of pre-existing diabetes on cancer-specific mortality has been evaluated in several studies, with less clear results. Other epidemiological and experimental studies focused on the potential role of diabetes medications, mainly metformin, in cancer development in women. The correct understanding of the link between T2D and gynecologic cancer risk and mortality is currently imperative to possibly modify screening and diagnostic-therapeutic protocols in the future.
Quality and future of clinical laboratories: the Vico’s whole cyclical theory of the recurring cycles
Authors: Plebani Mario 
Published: February 2018

Abstract
In the last few decades, laboratory medicine has undergone monumental changes, and laboratory technology, which has made enormous advances, now has new clinical applications thanks to the identification of a growing number of biomarkers and risk factors conducive to the promotion of predictive and preventive interventions that have enhanced the role of laboratory medicine in health care delivering. However, the paradigm shift in the past 50 years has led to a gap between laboratory and clinic, with an increased risk of inappropriateness in test request and interpretation, as well as the consolidation of analytical work in focused factories and megastructurers oriented only toward achieving greater volumes, decreasing cost per test and generating a vision of laboratory services as simple commodities. A careful historical revision of the changing models for delivering laboratory services in the United States leads to the prediction that there are several reasons for counteracting the vision of clinical laboratory as a commodity, and restoring the true nature of laboratory services as an integral part of the diagnosis and therapy process. The present study, which reports on internal and external drivers for change, proposes an integrated vision of quality in laboratory medicine.
Magnetic and velocity fields in a dynamo operating at extremely small Ekman and magnetic Prandtl numbers
Authors: Šimkanin Ján , Kyselica Juraj 
Published: February 2018

AbstractNumerical simulations of the geodynamo are becoming more realistic because of advances in computer technology. Here, the geodynamo model is investigated numerically at the extremely low Ekman and magnetic Prandtl numbers using the PARODY dynamo code. These parameters are more realistic than those used in previous numerical studies of the geodynamo. Our model is based on the Boussinesq approximation and the temperature gradient between upper and lower boundaries is a source of convection. This study attempts to answer the question how realistic the geodynamo models are. Numerical results show that our dynamo belongs to the strong-field dynamos. The generated magnetic field is dipolar and large-scale while convection is small-scale and sheet-like flows (plumes) are preferred to a columnar convection. Scales of magnetic and velocity fields are separated, which enables hydromagnetic dynamos to maintain the magnetic field at the low magnetic Prandtl numbers. The inner core rotation rate is lower than that in previous geodynamo models. On the other hand, dimensional magnitudes of velocity and magnetic fields and those of the magnetic and viscous dissipation are larger than those expected in the Earth’s core due to our parameter range chosen.

Abstract
Hemolytic disease of the fetus and newborn (HDFN) due to anti-D antibodies is a well-known complication of rhesus (Rh) incompatibility, encountered in D-positive babies born to alloimmunized D-negative mothers who have been sensitized during previous labor or abortion. Here, we report a case of significant hemolytic disease of the newborn due to the presence of anti-D antibodies in an Rh-positive baby born to an Rh-positive mother. The boy presented at day 1 of life with neonatal jaundice and required intensive phototherapy. His hemoglobin (Hb) concentration gradually dropped from 17 g/dL to 6.6 g/dL. The blood bank workup revealed O Rh-positive blood group, with a positive direct antiglobulin test (DAT) and confirmed the presence of anti-D antibodies. His mother was typed as O Rh positive, with a negative DAT and positive anti-D. He required two blood transfusions, and his Hb stabilized at the age of 7 weeks. Anti-D HDFN is a rare complication of Rh-positive and Rh-weak positive pregnancies. The lack of awareness of this phenomenon is often a source of confusion for clinicians. A literature review of similar cases and possible explanations are discussed.
Effect of different management on quality and value production of pure beech stands in Slovakia
Authors: Štefančík Igor , Bošeľa Michal , Petráš Rudolf 
Published: February 2018

AbstractValue production is one of the most important information for comparing different management strategies in forestry. Although the value production of forest stands is affected by various factors (stem and assortment quality, stem dimension, stem injury, price of assortments), thinning can be considered as one of the most important one. This paper aims at the evaluation of qualitative and value production in homogeneous beech stands, which were managed by two different thinning types for period of 45 to 55 years: (i) – heavy thinning from below (C grade according to the German forest research institutes released in 1902) and (ii) – Štefančík´s free-crown thinning. The third variant was control (iii) – subplot with no interventions. Silvicultural quality characteristics of the lower half of the stem were assessed using a 4-class scale (A – the best quality, D – the worst quality). Assortment structure (commercial quality) was estimated for each stem by an assortment model developed in the past. Nearly 3,000 individual trees aged from 83 to 105 years from 23 subplots established across the Slovakia territory were assessed. The highest volume of the best silvicultural quality of stems (A class) has been reached in forests where Štefančík´s free-crown thinning was applied (57 – 85%) while the lowest (22 – 56%) on subplots with no management. The proportion of two best commercial quality assortments (I + II) was highest in forests managed by heavy thinning from below (21 – 29%) and the lowest when no treatment was applied (7 – 19%). The highest value production (expressed in € ha−1) was reached in the forests treated by free-crown thinning. Results suggested the overall positive impact of thinning on the increase of value production in beech forests. Particularly, the free-crown thinning focusing on selection of best quality trees should be preferred as it leads, besides its sufficient value production, to a higher vertical differentiation of the beech forests.
Land use changes and development of the non-forest woody vegetation in the Danubian Lowland in Slovakia
Authors: Supuka Ján , Šinka Karol 
Published: February 2018

AbstractThe aim of this paper is to assess the changes in the landscape structure of the Žitný Ostrov territory and in the woody species of the non-forest woody vegetation (NFWV) over the past 120 years. Within the assessed periods of 1892, 1949, 1969 and 2015, the shares of arable land increased by 17% while the ratio of the built-up areas with gardens increased by 3.7%. At the same time, natural habitats, grassland, waterlogged meadows and wetlands decreased by 26%. These changes, concerning small mosaic plots as well as large cultural blocks, were caused by the intensification of agriculture after 1948. Ecological stability and biodiversity of these areas has decreased. Thereafter 60 windbreaks were planted from 1951–1952 in an area of 30 ha. In total, 37 woody species were planted, of which 22 were alien species. After 25 years (in 1976), 19 of the same windbreaks were surveyed, observing 16 native and 12 alien woody species. During these periods, many rare alien and coniferous species died. In 2015, 13 windbreaks with 39 woody species were identified, both in the tree and the shrubby layer. The downside is that four of the long-time surviving species are invasive trees.

Published: February 2018

AbstractSelected forestry parameters were investigated in the system of trees and wood-destroying fungi in the natural forests of the Kyiv city on a gradient of recreational transformation. We investigated the vitality, age compositions, and health condition of woody plants (11 species), and species, systematic, trophic and spatial compositions of xylotrophic fungi (51 species, 224 findings of xylotrophs representing 34 genera, 20 families, 7 orders of divisions Basidiomycota; class Agaricomycetes). The results showed that communities of woody vegetation and xylotrophic fungi in forests depend on the degree of recreational transformation of the environment. Vitality, age compositions and health condition of trees altered species composition of xylotrophs.

Published: February 2018

AbstractThe spatial pattern of forest closely affects tree competition that drives the most of processes in forest ecosystems. Therefore, we focused on evaluation of the horizontal structure of high forest, coppice with standards and low forest in hornbeam-oak forests in the Protected Landscape Area Český kras (Czech Republic). The horizontal structure of tree layer individuals with crown projection centroids and natural regeneration was analysed for durmast oak (Quercus petraea(Matt.) Liebl.), European hornbeam (Carpinus betulusL.) and small-leaved linden (Tilia cordataMill.) stands. Horizontal structure of the tree stems of the studied tree species in high forest was random, in oak it was moderately regular. In coppice with standards it was random in oak, in hornbeam and linden it was aggregated within 3 – 5 m and random up to a larger spacing. In low forest at a distance of 4 – 6 m the horizontal structure of the three studied tree species was aggregated while it was random at a larger spacing. The horizontal structure of natural regeneration was aggregated in all forest types. In coppice with standards and high forest, parent stand had significant negative effect on the natural regeneration at smaller distance (to 1.4 m from the stem). Crown centroids were more regularly distributed than tree stems, especially in low forest (2.0 m) and in linden (2.3 m). Our results contribute to existing knowledge about silvicultural systems and their impact on hornbeam-oak forests with implications for forest management and nature protection.
