Ferric carboxymaltose vs. oral iron in the treatment of pregnant women with iron deficiency anemia: an international, open-label, randomized controlled trial (FER-ASAP)
Authors: Breymann Christian , Milman Nils , Mezzacasa Anna , Bernard Roubert , Dudenhausen Joachim 
Published: June 2016

Abstract

Objective:
To compare the efficacy and safety of intravenous ferric carboxymaltose (FCM) with first-line oral ferrous sulfate (FS) in pregnant women with iron deficiency anemia (IDA).

Materials and methods:
Pregnant women (n=252; gestational weeks 16–33) with IDA were randomized 1:1 to FCM (1000–1500 mg iron) or FS (200 mg iron/day) for 12 weeks. The primary objective was to compare efficacy; secondary objectives included safety and quality of life.

Results:
Hemoglobin (Hb) levels improved at comparable rates across both treatments; however, significantly more women achieved anemia correction with FCM vs. FS [Hb ≥11.0 g/dL; 84% vs. 70%; odds ratio (OR): 2.06, 95% confidence interval (CI): 1.07, 3.97; P=0.031] and within a shorter time frame (median 3.4 vs. 4.3 weeks). FCM treatment significantly improved vitality (P=0.025) and social functioning (P=0.049) prior to delivery. Treatment-related adverse events were experienced by 14 (FCM; 11%) and 19 (FS; 15%) women, with markedly higher rates of gastrointestinal disorders reported with FS (16 women) than with FCM (3 women). Newborn characteristics were similar across treatments.

Conclusions:
During late-stage pregnancy, FCM may be a more appropriate option than first-line oral iron for rapid and effective anemia correction, with additional benefits for vitality and social functioning.
A Monte Carlo-Based Method for Assessing the Measurement Uncertainty in the Training and Use of Artificial Neural Networks

Published: June 2016

Abstract
When an artificial neural network is used to determine the value of a physical quantity its result is usually presented without an uncertainty. This is due to the difficulty in determining the uncertainties related to the neural model. However, the result of a measurement can be considered valid only with its respective measurement uncertainty. Therefore, this article proposes a method of obtaining reliable results by measuring systems that use artificial neural networks. For this, it considers the Monte Carlo Method (MCM) for propagation of uncertainty distributions during the training and use of the artificial neural networks.
Classification of EEG Signals Using Adaptive Time-Frequency Distributions
Authors: Khan Nabeel A. , Ali Sadiq 
Published: June 2016

Abstract
Time-Frequency (t-f) distributions are frequently employed for analysis of new-born EEG signals because of their non-stationary characteristics. Most of the existing time-frequency distributions fail to concentrate energy for a multicomponent signal having multiple directions of energy distribution in the t-f domain. In order to analyse such signals, we propose an Adaptive Directional Time-Frequency Distribution (ADTFD). The ADTFD outperforms other adaptive kernel and fixed kernel TFDs in terms of its ability to achieve high resolution for EEG seizure signals. It is also shown that the ADTFD can be used to define new time-frequency features that can lead to better classification of EEG signals, e.g. the use of the ADTFD leads to 97.5% total accuracy, which is by 2% more than the results achieved by the other methods.
Suppressing Side-Lobes of Linear Phased Array of Micro-Strip Antennas with Simulation-Based Optimization
Authors: Kozieł Sławomir , Ogurtsov Stanislav , Bekasiewicz Adrian 
Published: June 2016

Abstract
A simulation-based optimization approach to design of phase excitation tapers for linear phased antenna arrays is presented. The design optimization process is accelerated by means of Surrogate-Based Optimization (SBO); it uses a coarse-mesh surrogate of the array element for adjusting the array’s active reflection coefficient responses and a fast surrogate of the antenna array radiation pattern. The primary optimization objective is to minimize side-lobes in the principal plane of the radiation pattern while scanning the main beam. The optimization outcome is a set of element phase excitation tapers versus the scan angle. The design objectives are evaluated at the high fidelity level of description using simulations of the discrete electromagnetic model of the entire array so that the effects of element coupling and other possible interaction within the array structure are accounted for. At the same time, the optimization process is fast due to SBO. Performance and numerical cost of the approach are demonstrated by optimizing a 16-element linear array of microstrip antennas. Experimental verification has been carried out for a manufactured prototype of the optimized array. It demonstrates good agreement between the radiation patterns obtained from simulations and from physical measurements (the latter constructed through superposition of the measured element patterns).

Authors: Tadeusiewicz Michał , Hałgas Stanisław 
Published: June 2016

Abstract
The paper deals with fault diagnosis of nonlinear analogue integrated circuits. Soft spot short defects are analysed taking into account variations of the circuit parameters due to physical imperfections as well as self-heating of the chip. A method enabling to detect, locate and estimate the value of a spot defect has been developed. For this purpose an appropriate objective function was minimized using an optimization procedure based on the Fibonacci method. The proposed approach exploits DC measurements in the test phase, performed at a limited number of accessible points. For illustration three numerical examples are given.

Authors: Srakar Andrej , Hren Rok , Rupel Valentina Prevolnik 
Published: June 2016

Abstract
Background and Purpose: Chronic diseases and associated co-morbidities are highly prevalent among elderly and are associated with an increase in health services utilization which in turn raises health care expenditures throughout industrialized societies. However, health care utilization in elderly is still inadequately understood, particularly regarding the differences among European jurisdictions. In our article, we use dataset of Wave 5 of SHARE survey to study the utilization of health care in older Europeans in 15 European countries.
Design/Methodology/Approach: We investigate relationships between factors such as age, gender, income, education and health variables and the utilization of various types of health services. We apply regression modeling to study the determinants of health utilization (different socioeconomic and health variables) of older people.
Results: We show some significant differences between determinants of health utilization in terms of probability and frequency of usage. We also explore patterns between welfare regimes, taking Eastern European jurisdictions as a reference category. Finally, we show that in a simple causal model the provision of formal and/or informal homecare serves as a complement to utilization of health care services.
Conclusion: Results of our article are important for the management of health care facilities in terms of health care usage by older people, and can be of value to health care providers and policy makers in the field.
Experimental investigation on tensile and Charpy impact behavior of Kevlar/S-glass/epoxy hybrid composite laminates
Authors: Erkliğ Ahmet , Bulut Mehmet 
Published: June 2016

Abstract
The aim of this study is to evaluate the effect of hybridizing Kevlar and glass fibers on the tensile and Charpy impact properties of their composites. Produced hybrid samples were designed as unbalanced and asymmetric structures in terms of different mixing ratios between woven Kevlar and S-glass fibers, and their tensile properties were determined using ASTM standards. A series of Charpy impact tests were performed to evaluate the amount of impact strength and absorbed energy by impacting each side of the hybrid composite samples. When the hybrid samples were impacted on the surface of the Kevlar side, they exhibited higher impact resistance compared with glass side impact. The resulting degree of hybridization effects showed that addition of Kevlar layers instead of glass layers contributed a significant increase in impact strength and absorbed energy of the overall composite laminate.
Effect of fillers on the metallization of laser-structured polymer parts
Authors: Fischer Andreas J. , Meister Steve , Drummer Dietmar 
Published: June 2016

Abstract
Molded interconnect devices offer great potential as a substitute for circuit boards, especially regarding three-dimensional shaping and functional integration. Applying circuits to polymer substrates can be performed by means of LPKF laser direct structuring® (LDS). There, the matrix polymer is filled with a special metal additive, enabling laser activation and subsequent metallization. Important effects emerge from additional inorganic fillers inside the matrix polymer, e.g. the (thermo)mechanical behavior and the processing properties. In this work, the degree to which inorganic fillers affect the quality of metallization is investigated. An increase in the plating thickness was successfully achieved by adding varying amounts of talc platelets (diameter 7 μm) to a PA10T-based copolyamide filled with 4 and 8 wt% LDS additive, in contrast to poor metal deposition adding only LDS additive. Additionally, talc and glass spheres with a diameter of 50 μm were used, leading to unsatisfactory metallization results. To explain this behavior, adhering LDS particles were found on the talc platelets with a diameter of 7 μm on the surface of the laser-structured specimen. The talc platelets and glass spheres of 50 μm were not available in sufficient dimensions on the surface and thus led to worse plating results.
The influence of pH and reaction time on the formation of FeSe2 upon selenite reduction by nano-sized pyrite-greigite

Published: June 2016

Abstract
The influence of pH and reaction time on the formation of FeSe2 by reductive precipitation of Se(IV) with nano-sized pyrite-greigite was investigated. Reductive precipitation is an effective method of attenuating the mobility of 79Se, which is foreseen to be a dangerous radioisotope for the geological disposal of high-level radioactive waste (HLW). The results indicated that Se(0)was formed at pH <4.05, whereas, at pH > 6.07, considerable amount of FeSe2 was formed along with Se(0). These observations are in agreement with the thermodynamic predictions reported in this work. Furthermore, the formation of FeSe2 was found to continue by increasing the reaction time, indicating that the Se(0) formed in the early reaction stage is gradually transformed to FeSe2 upon the depletion of aqueous Se(IV). Since FeSe2 has a stronger reactivity than pyrite, it was proposed that greigite, rather than pyrite, was responsible for the formation of FeSe2. The findings in this study are of interest for key geochemical processes governing the mobility of toxic 79Se in the environment in presence of iron sulfides.

Abstract
In this study, the MOF concept contributed to the preparation of a novel, bone-ablating agent composed of Cu(II) using the in vivo generator 166Dy/166Ho and 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetramethylene phosphonic acid (DOTMP). The product was characterized (IR, elemental analysis: CHN, ICM-MS, PIXE, DLS, XRD) and quality-controlled (radio-thin layer chromatography (RTLC)). The stability and in vitro hydroxyapatite binding was checked up to one week at 37°C in human serum. Radio-MOF crystals and colloidal radio-MOF particles were obtained by varying the synthesizing conditions (including pH and temperature), and they had similar IR patterns and similar elemental analysis results. The estimated chemical formula was [1Lu-1Cu-1Cl-1DOTMP] for both. The final product was synthesized at pH = 8 while stirring at room temperature using 166Dy/166Ho-nitrate, CuCl2, and DOTMP (yield > 99%, RTLC). Dynamic light scattering (DLS) measurements showed particles in the size range of 60 to 100 nm for the resultant radio-MOF particles (RMP). In vitro binding experiments showed acceptable bone-seeking affinity of the prepared formula even after one week of storage in human serum at 37°C. Importantly, this is the first study of the use of the MOF concept to provide a highly-stable organometallic compound containing 166Dy/166Ho in vivo generator for bone marrow ablation.

Abstract90Nb has an intermediate half-life of 14.6 h, a high positron branching of 53% and optimalβ+emission energy of onlyEmean0.35 MeV per decay. These favorable characteristics suggest it may be a potential candidate for application inimmuno-PET. Our recent aim was to conduct studies on distribution coefficients for ZrIVand NbVin mixtures of HCl/H2O2and HCl/oxalic acid for anion exchange resin (AG 1 × 8) and UTEVA resin to develop a “direct flow” separation strategy for90Nb. The direct flow concept refers to a separation accomplished using a single eluent on multiple columns, effectively streamlining the separation process and increasing the time efficiency. Finally, we also demonstrated that this separation strategy is applicable to the production of the positron emitter90Nb via the irradiation of molybdenum targets and isolation of90Nb from the irradiated molybdenum target.
Evaluation of consequence due to higher hydrazine content in partitioning stream of PUREX process
Authors: Kumar K. Suresh 
Published: June 2016

Abstract
Hydrazine nitrate is being used as a stabilizer for U(IV) as well as Pu(III) during partitioning of Pu in PUREX process by scavenging the nitrous acid present along with nitric acid. As hydrazine hydrate as well as its salts have been successfully used for scrubbing of degradation products of TBP to aqueous phase, experiments were conducted to evaluate the consequence of hydrazine content during Pu partitioning. It was observed that higher amount of hydrazine nitrate along with uranous nitrate in the partitioning stream of PUREX process leads to build up of DBP in aqueous phase and resulted in precipitation of Pu.

The material for scientific experiments was the ducklings of cross STAR 53 H.Y. Experiment was carried out by group-analog method. We determined the optimal content of crude fat in fodder of young ducks at the first stage of experiment and the best source of lipids at second stage. We increased the crude fat in duckling feed by the introduction of sunflower oil at first stage. The amount of fat in the duck feed was 5% in control group and this were 3% and 7% in group II and III. The ducks from experimental groups received feed with sunflower oil at the second stage of experiment, the ducks of group II and III obtained feed from soya, rapeseed, and palm fat. Feeding the ducks was done per group twice per day – in morning and evening.</p><p>It was registered that the feeding of 8-14 days ducks by food with crude fat of 7% plausible increased the digestibility of protein by 3.2%, of fat by 5.1%, and nitrogen-free extractives matters by 2.7%. At the same time the use of feed for 36-42 days ducks with crude fat of 7% allows to get the best results with the more higher level of protein and fat digestibility by 4.9% and 4.8% respectively. The use of feed with the addition of soybean oil for duck feeding have a positive effect towards increasing the level of digestibility of organic matter, protein, fat, and fiber in all the duck age groups.

Labmagenulzera bei Schlachtrindern in Österreich
Authors: Beer Theresa , Wittek Thomas , Hund Alexandra 
Published: June 2016

ZusammenfassungZiel: Im Rahmen dieser Pilotstudie erfolgte erstmals eine Bestimmung der Prävalenz von Labmagengeschwüren bei Rindern in Österreich. Außerdem wurden Managementfaktoren evaluiert, die möglicherweise die Bildung von Labmagengeschwüren begünstigen, und der diagnostische Wert von Tests für okkultes Blut im Kot für die Diagnose von Labmagengeschwüren geprüft. Material und Methoden: Bei 91 Mastbullen, 33 Kühen und 91 Kälbern wurden nach der Schlachtung die Labmägen auf Geschwüre untersucht. Festgestellte Ulzera sowie der pH-Wert des Lagmageninhalts wurden dokumentiert und der Kot auf okkultes Blut getestet. Ferner erfolgte eine Erfassung der Fleischigkeits- und Fettklassen der Tierkörper. Die telefonisch kontaktierten Tierbesitzer konnten freiwillig an einer Befragung zu Managementund Fütterungspraktiken mit potenziellem Einfluss auf die Gesundheit des Labmagens teilnehmen.Ergebnisse: Der pH-Wert des Labmageninhalts betrug im Median 3,0 bei Kälbern, 3,6 bei Bullen und 3,9 bei Kühen. Mehr als die Hälfte der Tiere hatten Labmagengeschwüre der am wenigsten schwerwiegenden Art. Beide Tests für okkultes Blut im Kot waren nicht geeignet, diese Art von Ulzera nachzuweisen. Durch die Befragung ließen sich keine eindeutigen Faktoren feststellen, die für die Bildung von Labmagengeschwüren ursächlich sein könnten. Schlussfolgerung und klinische Relevanz: Die Ergebnisse legen nahe, dass die Haltungssysteme in Österreich die Bildung geringgradiger Labmagengeschwüre begünstigen. Da es beim Rind keine Möglichkeit gibt, dies in vivo zu erforschen, bleiben weiterreichende Schlussfolgerungen rein spekulativ. Weitere Aspekte, z. B. die Rolle von Bakterien bei der Bildung von Geschwüren oder ihre Auswirkungen auf Produktivität und Tierwohl, sollten in folgenden Studien untersucht werden. Ebenso sollten die Ergebnisse dieser Pilotstudie in größeren experimentellen Studien bestätigt werden.

ZusammenfassungIn einem geschlossenen Ferkelerzeugerbetrieb erkrankten etwa 80% der 7 Wochen alten Ferkel in der Aufzucht an einer fieberhaften Atemwegsinfektion mit einer Letalität von 5%. Neben eitrigen Broncho - pneumonien in Kombination mit interstitiellen Pneumonien insbesondere im Spitzen- und Mittellappenbereich lagen fibrinöse Serositiden in der Brust- und Bauchhöhle vor. Weiterführend gelang der Nachweis des nichtpandemischen Stamms von porzinem Influenza-A-Virus (FLUAVsw) Subtyp H1avN1. Die molekulargenetischen Untersuchungen auf Mycoplasma (M.) hyopneumoniae und PRRSV verliefen negativ, doch konnten M. hyorhinis und Haemophilus parasuis aus serösen Häuten nach - gewiesen werden. Die möglicherweise unterschätzte Bedeutung von M. hyorhinis als Kofaktor bei Virusinfektionen und Verursacher von Spitzenlappenpneumonien wird hervorgehoben und aufgezeigt. Die Muttersauen des Bestands waren mit einem Influenzaimpfstoff geimpft worden, der den Subtyp H1avN1 abdeckt. Nur 33% der untersuchten Ferkel hatten in der 7. Lebenswoche noch maternale Anti körper. Die Schwierigkeit einer Prophylaxe von Erkrankungen durch FLUAVsw bei Ferkeln mit nachlassender maternaler Immunität wird deutlich, wenn Impfstoffe erst ab dem 56. Lebenstag eingesetzt werden dürfen.
