FIRST NOTICE OF PHYTOPHTHORA CROWN AND ROOT ROT OF EUPHORBIA PULCHERRIMA IN POLISH GREENHOUSES
Authors: Orlikowski Leszek B. , Ptaszek Magdalena
Published: January 2014

The plant pathogen, Phytophthora cryptogea, was recovered from 4/5 of the 75 poinsettias collected from two greenhouse farms. The poinsettias showed stunting and wilting as well as stem base and root rot symptoms. Representative isolates of the species from two poinsettia cultivars, colonized stem parts, leaf petioles, leaf blades and root parts. Stem parts of 6 cultivars were colonized at a slower rate than other poinsettia organs. Isolate from Euphorbia pulcherrima also colonized stem parts and leaf blades of E. amygdaloides, E. cyparissias, and E. polychroma. Isolates of P. cryptogea from the other 6 plant hosts, colonized the overground parts of poinsettia cv. Allegro. This is the first report describing symptoms and colonization of poinsettia cultivars by P. cryptogea in Poland.

Published: January 2014

Ambrosia artemisiifolia distribution in the Ukraine for the 1973-2013 period was analyzed. The infested areas were consequently grouped into 6 categories. Intense infestation in the region was the reason for the analysis and the categorization. A practical approach to the A. artemisiifolia surveillance system which complied with the International Standards for Phytosanitary Measures concerning “a pest free area”, “pest free places of production”, “pest free production sites” and “an area of low pest prevalence” was recommended. This action should drive the policy-making process to underpin national legislation regarding invasive species. The opportunity also presents itself for improved communications with growers and stakeholders because of the more transparent and cost effective system of A. artemisiifolia surveillance offered. There would be a chance to slow down the A. artemisiifolia invasion even though this invasive species has already occupied 3.6 million hectares.
ANALYSIS OF THE INTERACTION BETWEEN TOMATO TORRADO VIRUS PROTEINS USING THE YEAST TWO-HYBRID SYSTEM
Authors: Budziszewska Marta , Obrępalska-Stęplowska Aleksandra
Published: January 2014

Ten years ago for the first time the new picorna-like virus species - Tomato torrado virus (ToTV) - was found and described on tomato plants. The isolates of this pathogen were reported in Europe, America, and Oceania including Australia. Because of its unique biological and molecular features, ToTV was classified to the new genus Torradovirus, in the Secoviridae family. In Poland, three isolates: Wal’03, Kra, and Ros ToTV were identified on greenhouse tomato cultivars. At present, the biology and the genome structure of this virus are characterised. But there is no data extending beyond the bioinformatics analyses about the function of viral proteins, polyproteins, and non-coding sequences, as well as possible interactions between viral, host and vector factors that may be important for the infection process, encapsidation, transport in plants, and transmission. In this study, we have undertaken a search for the possible protein-protein interaction of ToTV encoded proteins using the yeast two-hybrid (Y2H) system. The viral genome fragments covering full sequences for nine known proteins of ToTV were amplified using specific primers with characteristic recombination sites. This process enabled the construction of basic entry clones for each protein that further facilitated manipulations with prepared constructs using Gateway technology. Two-hybrid assays were performed in the yeast strain and tested interactions of ToTV proteins were analysed in several combinations using auxotrophy markers. Our analyses did not reveal the presence of interactions between ToTV domains. Surprisingly, no interactions were found in the case of various CP subunits as well as between CP subunits and 3A protein, that in some virus families are known to play a role in viral life cycle. This role includes virion assembly or cell-to-cell transport. The lack of interactions may be a result of the limitation of this experimental system, or suggest that these proteins may interact indirectly, or require the presence of genomic RNAs or some host factors.
MULTILINGUALISM AT THE COURT OF JUSTICE OF THE EUROPEAN UNION: THEORETICAL AND PRACTICAL ASPECTS
Authors: Łachacz Olga , Mańko Rafał
Published: January 2014

The paper analyses and evaluates the linguistic policy of the Court of Justice of the European Union against the background of other multilingual courts and in the light of theories of legal interpretation. Multilingualism has a direct impact upon legal interpretation at the Court, displacing traditional approaches (intentionalism, textualism) with a hermeneutic paradigm. It also creates challenges to the acceptance of the Court’s case-law in the Member States, which seem to have been adequately tackled by the Court’s idiosyncratic translation policy.

Authors: Poskas G. , Poskas P. , Simonis A.
Published: January 2014

Ignalina NPP was operating two RBMK-1500 reactors which are under decommissioning now. In this paper, analysis on radwaste management alternatives during the dismantling of systems with low level contamination and different types of components in buildings 117/1 and V1 are presented. After situation analysis and collection of the primary information related to components' physical and radiological characteristics, location and other data, two alternatives for radwaste management during the dismantling were formulated and evaluated: the first one (A1) when the decontamination of the dismantled components is performed (if it is reasonable), and the second one (A2) when no decontamination of the dismantled components is performed and after the dismantling, the components are routed to appropriate waste storage or disposal sites. To select the preferable alternative, MCDA method – AHP (Analytic Hierarchy Process) is applied. Hierarchical lists of decision criteria, necessary for assessment of alternatives performance, are formulated. Quantitative decision criteria values for these alternatives are calculated using software DECRAD, which was developed by Lithuanian Energy Institute Nuclear Engineering Laboratory. Qualitative decision criteria are evaluated using expert judgment. Analysis results show that alternative A1 has a preference against alternative A2.
Technologies, Democracy and Digital Citizenship: Examining Australian Policy Intersections and the Implications for School Leadership
Authors: Moyle Kathryn
Published: January 2014

There are intersections that can occur between the respective peak Australian school education policy agendas. These policies include the use of technologies in classrooms to improve teaching and learning as promoted through the Melbourne Declaration on Educational Goals for Young Australians and the Australian Curriculum; and the implementation of professional standards as outlined in the Australian Professional Standard for Principals and the Australian Professional Standards for Teachers. These policies create expectations of school leaders to bring about change in classrooms and across their schools, often described as bringing about ‘quality teaching’ and ‘school improvement’. These policies indicate that Australian children should develop ‘democratic values’, and that school principals should exercise ‘democratic values’ in their schools. The national approaches to the implementation of these policies however, is largely silent on promoting learning that fosters democracy through education, or about making connections between teaching and learning with technologies, school leadership and living in a democracy. Yet the policies promote these connections and alignments. Furthermore, understanding democratic values, knowing what is a democracy, and being able to use technologies in democratic ways, has to be learned and practiced. Through the lens of the use of technologies to build digital citizenship and to achieve democratic processes and outcomes in schools, these policy complexities are examined in order to consider some of the implications for school leadership.

Published: January 2014

Historically, only few chemicals have been identified as neurodevelopmental toxicants, however, concern remains, and has recently increased, based upon the association between chemical exposures and increased developmental disorders. Diminution in motor speed and latency has been reported in preschool children from agricultural communities. Organophosphorus compounds (OPs) are pesticides due to their acute insecticidal effects mediated by the inhibition of acetylcholinesterase, although other esterases as neuropathy target esterase (NTE) can also be inhibited. Other neurological and neurodevelopmental toxic effects with unknown targets have been reported after chronic exposure to OPs in vivo. We studied the initial stages of retinoic acid acid-triggered differentiation of pluripotent cells towards neural progenitors derived from human embryonal carcinoma stem cells to determine if neuropathic OP, mipafox, and non-neuropathic OP, paraoxon, are able to alter differentiation of neural precursor cells in vitro. Exposure to 1 µM paraoxon (non-cytotoxic concentrations) altered the expression of different genes involved in signaling pathways related to chromatin assembly and nucleosome integrity. Conversely, exposure to 5 µM mipafox, a known inhibitor of NTE activity, showed no significant changes on gene expression. We conclude that 1 µM paraoxon could affect the initial stage of in vitro neurodifferentiation possibly due to a teratogenic effect, while the absence of transcriptional alterations by mipafox exposure did not allow us to conclude a possible effect on neurodifferentiation pathways at the tested concentration.

Emerging non-volatile memories based on resistive switching mechanisms attract intense R&D efforts from both academia and industry. Oxide-based Resistive Random Acces Memories (OxRAM) gather noteworthy performances, such as fast write/read speed, low power and high endurance outperforming therefore conventional Flash memories. To fully explore new design concepts such as distributed memory in logic, OxRAM compact models have to be developed and implemented into electrical simulators to assess performances at a circuit level. In this paper, we present compact models of the bipolar OxRAM memory based on physical phenomenons. This model was implemented in electrical simulators for single device up to circuit level.
A Concept for the Control of Pore Size in Superalloy Membranes
Authors: Rösler Joachim , Krause Waldemar , Hinze Björn
Published: January 2014

A new method to adjust the pore size in superalloy membranes is shown, utilizing controlled cooling from solution heat treatment of the solid superalloy. Hereby, the nucleation rate and, thus, the size of the γ'-precipitates can be varied to a large extent. This leads to a corresponding variation in the pore size once the membrane material is produced by directional coarsening of the γ'-phase to an interconnected network and subsequent selective extraction of the γ-phase. Furthermore, it was found that coherent and incoherent γ'-precipitates can be used alike to fabricate superalloy membranes, and yet, result in vastly different pore morphologies. The findings widen the application range of this novel material class.

Published: January 2014

The synthesis of a variety of 1-aryl-7-phenylaminoisoquinolinequinones from 1,4-benzoquinone and arylaldehydes via the respective 1-arylisoquinolinequinones is reported. The cyclic voltammograms of the new compounds exhibit two one-electron reduction waves to the corresponding radical-anion and dianion and two quasi-reversible oxidation peaks. The half-wave potential values (EI½) of the members of the series have proven sensitive to the electron-donor effect of the aryl group (phenyl, 2-thienyl, 2-furyl) at the 1-position as well as to the phenylamino groups (anilino, p-anisidino) at the 7-position. The antiproliferative activity of the new compounds was evaluated in vitro using the MTT colorimetric method against one normal cell line (MRC-5 lung fibroblasts) and two human cancer cell lines: AGS human gastric adenocarcinoma and HL-60 human promyelocytic leukemia cells in 72-h drug exposure assays. Among the series, compounds 5a, 5b, 5g, 5h, 6a and 6d exhibited interesting antiproliferative activities against human gastric adenocarcinoma. The 1-arylisoquinolinequinone 6a was found to be the most promising active compound against the tested cancer cell lines in terms of IC50 values (1.19; 1.24 µM) and selectivity index (IS: 3.08; 2.96), respect to the anti-cancer agent etoposide used as reference (IS: 0.57; 0.14).

Multiple Vehicle Cooperative Localization with Spatial Registration Based on a Probability Hypothesis Density Filter
Authors: Zhang Feihu , Buckl Christian , Knoll Alois
Published: January 2014

This paper studies the problem of multiple vehicle cooperative localization with spatial registration in the formulation of the probability hypothesis density (PHD) filter. Assuming vehicles are equipped with proprioceptive and exteroceptive sensors (with biases) to cooperatively localize positions, a simultaneous solution for joint spatial registration and state estimation is proposed. For this, we rely on the sequential Monte Carlo implementation of the PHD filtering. Compared to other methods, the concept of multiple vehicle cooperative localization with spatial registration is first proposed under Random Finite Set Theory. In addition, the proposed solution also addresses the challenges for multiple vehicle cooperative localization, e.g., the communication bandwidth issue and data association uncertainty. The simulation result demonstrates its reliability and feasibility in large-scale environments.
Evaluation of Ergonomic Risk of Manual Handling of Patients with MAPO Index and its Relationship with Incidence of Low Back Pain among Nurses
Authors: Saremi Mahnaz , Khayati Fatemeh
Published: January 2014

Low back pain (LBP) is the most common and most costly musculoskeletal disorder among nursing profession. The ergonomic risk factors are common causes of lumbar injury. This study aims to assess the risk of LBP among nurses in different wards of an Iranian subspecialty hospital by means of MAPO method and to investigate if there is any relationship between calculated index and the self-reported LBP. The study was conducted in 16 sections of an Iranian subspecialty hospital including 174 wards. Exposed nursing staff (N=54) were asked to report LBP experiences in the past year. Our results indicated approximately 90% of examined wards were in the red band while only 9% were in the yellow and 1% in the green bands. Among all nurses who worked in the high risk wards, 25% reported suffering LBP during the past 12 months. However, 16% of those who were in the medium risk wards also experienced LBP in the past year. Chi-square test showed a significant relationship between LBP incidence and the level of MAPO index (p=0.004). This study suggests that the frequency of LBP among nurses is higher than the general population. The most studied wards felt in the red band, indicating the elevated risk for low back in the majority of hospital wards. It is therefore necessary to implement an ergonomic program in order to modify the observed deleterious condition as soon as possible.

Published: January 2014

Main causes for discomfort experienced by vehicle drivers during driving were investigated using a rigid-body model originally developed in the AnyBody Modeling System [. The interactions between the human body and the car-seat in various combinations of seat-pan/backrest inclinations and the effect of pedal spring stiffness were analyzed using an inverse dynamics approach. To deal with the muscle redundancy problem, (i.e. the problem with the human-body containing more muscles than necessary to drive its degrees of freedom) a minimum-fatigue criterion [ was utilized. The results show that various seat adjustments (e.g., seat-pan and backrest inclinations) and the pedal spring stiffness have complex influences on the muscle activation and spinal joint forces of the human body. From the results, an optimal adjustment for the car-seat is proposed, i.e. the backrest inclination is 10° and the seat-pan inclination is between 0o to 5 o. This study can in general capture the overall interactions between human body and environment (i.e. the maximum muscle activity and spine forces), which is thought to be the factors of driving fatigue.
Investigation of Crack Line Offset of Fracture Splitting Connecting Rod
Authors: Yang Hong Yu , Kou Shu Qing , Gao Wen Qiang , Yang Shen Hua
Published: January 2014

Fracture line offset is the main defect in connecting rod fracture splitting processing, which seriously affects the using performance of connecting rod. In order to control this defect more effectively, the basic reason why this defect occurs was researched according to the theory of fracture mechanics, and the method of numerical simulation was used in this paper. The results show that when the applied load is nonparallel to the axis of a connecting rod, the first principle stress on the theoretical fracture surface is not perpendicular to the theoretical fracture line and the stress distribution is asymmetric on both sides of notches, which leads the type of fracture to turn into mixed mode I-II from mode I. As a result, the defect of fracture line offset occurs. Furthermore, the main factors leading to skew load were analyzed in actual production, and some effective measures were proposed to avoid the occurrence of this defect. This is significant in controlling the quality of connecting rod fracture splitting.

Published: January 2014

Vibration protection of the piping in nuclear power plants (NPPs) is critical for safety operation of NPPs. In order to improve the anti-shock ability of pipes in NPPs, the application feasibility of the elastomer damper in piping protection is investigated. The numerical analysis and the shock test are utilized to compare performances between the elastomer damper and the hydraulic oil damper, which is widely utilized in NPPs currently. The comparison results prove that the recoil force of the elastomer damper to the system is smaller. Moreover, the shock mitigation process of the elastomer damper is more smoothly. Therefore, the performance characteristics of the elastomer damper can well meet the requirements of vibration protection for pipes in NPPs. It can be used in NPPs in the future.

The flow of syndiotactic 1,2-polybutadiene (s-PB) filled with carbon nanotubes (CNTs) nanocomposites behave quite differently from Newtonian fluid, they exhibit both viscous and elastic characteristic and are termed as viscoelastic fluid. The viscoelastic properties can be determined by a Rheometer. In this studies a parallel plates arrangement where the upper plate is being rotated/oscillated with a sine wave and the stress and phase angles were measured. From our study on syndiotactic 1,2-polybutadiene and its nanocomposites with carbon nanotubes (CNTs), the results show that for a fixed amplitude and temperature, the storage and loss modulus increase with the increase of frequency. At low frequency the s-PB/ CNTs nanocomposites melts behaved more like a viscous liquid and changed the behavior into more elastic at high frequency.

A Numerical Analysis of 3D Soil Arching in Piled Embankments
Authors: Zhao Min , Cao Wei Ping
Published: January 2014

3D Soil arching has an important influence on the bearing and deformation characteristics of piled reinforced embankments. The effect of the embankment height, pile-cap clear spacing, cohesion and internal friction angle of the embankment fill on pile efficacy was analyzed by numerical method in this paper. The results indicate that the pile efficacy increases gradually during embankment filling and remains nearly unchanged at the end of embankment filling. The ratio of the embankment height to pile-cap clear spacing greatly influence the pile efficacy. The bigger the ratio, the bigger the pile efficacy. The internal friction angle of the fill material also has somewhat influence while the tensile strength of horizontal reinforcement and cohesion of the embankment fill have little effect on the pile efficacy.

Published: January 2014

The complex interaction between the pile and surrounding soil significantly affects the behavior of the piled reinforced embankment. In this paper, a 3D numerical model of piled reinforced embankment was set up to explore the development of the settlement of the pile and the surrounding soft soils during the embankment filling as well as the subsequent consolidation of the soil. The evolution of the pile axial force, the skin friction and the neutral plane depth was also studied. The results show that the settlement of the pile and surrounding soil, the pile axial force, the skin friction along the pile shaft and the neutral plane depth during the embankment filling and the consolidation process experienced a complicated evolution.

Published: January 2014

Welded tubular structures are widely used in many constructions, such as offshore platforms, which are all consisted of welded tubular members. There is a stress concentration at the intersection between chord and brace. When subjected to loads, a crack exists in the weld toe at the intersection. Then the propagation of the crack leads to failure of the joint. So the static strength of rectangular hollow section (RHS) T-joints with local chord reinforcement under in-plane bending load is investigated by using finite element method. To study the effect of the chord reinforcement of a RHS T-joint, overall 18 T-joint models with different chord reinforcements have been analyzed numerically. This paper presents the results of a detailed parametric study of the static strength of in-plane bending loaded tubular T-joints with reinforced chord. The study, carried out using non-linear finite elements, demonstrated the accuracy of the finite element analysis to investigate the effects of different geometric parameters which influence the static strength of the stiffened joints. It is found that the effect of the chord thickness near the intersection is significant in improving the ultimate capacity of T-joint models. The ultimate strength enhances as the length of the chord reinforcement becomes longer and the chord wall thickness becomes larger. The effect of the chord wall thickness on the static strength of T-joints are remarkable. However, increasing the length of the reinforced chord to improve the static strength of Tubular T-joint is relatively ineffective.
