Methanolysis of 2-Cyanopyridine in the Coordination Sphere of Manganese(II). The Structure of Mn4L6Cl2 cluster (L = Methyl Picolinimidate)

The reaction of 2-cyanopyridine and Mn(II) in methanol solution led to the formation of a Mn4L6Cl2 cluster 1 containing O-methyl picolimidate as a ligand (L). The coordination of 2-cyanopyridine to the Mn(II) ion as a chelating bidentate ligand activated the CN triple bond which subsequently suffered a nucleophilic attack by CH3OH. Complex 1 was characterized by standard techniques including microanalysis, IR spectroscopy, ESI spectrometry, and magnetic susceptibility measurements. The crystal structure of 1 was determined by X-ray diffraction techniques, and the crystallographic studies revealed a planar-diamond array for 1 where the six monoanionic picolinimidates act as chelating ligands through the two nitrogen atoms.
Preliminary study on precision dosimetry using radio-photoluminescent glass dosimeters for future use in radiotherapy

The radio-photoluminescence glass dosimetry test was carried out carefully. For the test, a therapy level Co-60 gamma-ray beam was used for the irradiation of the known doses to the dosimeters with the standard uncertainty of 0.7 % (k = 1). A weak negative correlation between mass and response of the glass dosimeter was found with Pearson’s correlation coefficient -0.27, -0.29, -0.29, -0.27 and -0.26 for glass dosimeters irradiated at 1, 3, 5, 7 and 9 Gy radiation doses, respectively. It has been confirmed that the statistical uncertainty of the radio-photoluminescence glass dosimetry can be obtained within 1 % from the repeatability test.
IMAPBOOK: Engaging Young Readers with Games

Glenn Smith, Associate Professor in the College of Education at the University of South Florida (USF), pondered the challenge presented by the need to transform his research into a marketable product. For more than two years he had worked with doctoral students and his wife, Mieke Caris, to develop a platform for embedding games into online books. Classroom testing in the Netherlands and elsewhere had demonstrated the efficacy of the approach. The next step required was commercialization, without which the benefits of using the technology could not be realized on a broader scale.
The Influence of Pb(Mg1/3Nb2/3)O3-doping on the thermoelectric properties of BaTiO3 ceramics

ABSTRACT The low-lead (1-x)Pb(Mg1/3Nb2/3)O3-xBaTiO3 (x = 0, 0.025, 0.05, 0.075, 0.10 and 0.15) ceramics were fabricated by a two-step solid-state reaction route. The X-ray diffraction characterization confirms a perovskite crystal structure with tetragonal symmetry at room temperature (except for x = 0.15). SEM images indicate that all ceramic samples are dense and compact, with the grain size of 2–6 μm. Along with the increase of Pb(Mg1/3Nb2/3)O3 content, the electrical conductivity increases, and the Seebeck coefficient and the thermal conductivity decrease. With increasing temperature, σ and α increase and κ decreases. In general, adding Pb(Mg1/3Nb2/3)O3 to BaTiO3 leads to an improvement of the thermoelectric figure of merit ZT. The results are explained on the basis of structural, morphological and compositional changes.
Lexicographic Study of Synonymy: Clarifying Semantic Similarity between Words

The problem of determining semantic similarity between words affects the understanding of synonymy and creates obstacles to the work oflexico graphers. The study was carried out as a part ofa larger research project on expert assessment of synonymic rows in RuWordNet thesaurus (a WordNet–like thesaurus for the Russian language). The aim of this study is to analyze RuWordNet thesaurus and compare it with classical dictionaries of Russian synonyms. For this purpose, the authors singled out entry words (adjectives N = 68 and verbs N = 117) and their analogues (adjectives N = 558 and verbs N = 1410) from the New Explanatory Dictionary of Russian Synonyms by Yu. Apresyan (NEDS). An analogue is viewed as aword whose meaning essentially intersects with the general meaning of a given synonymic row, although it lacks the needed semantic similarity that could indicate the presence of synonymy or near–synonymy (Apresyan). The quantitative analysis based on the breadth–first search (BFS) algorithm estimated the distance between each pair entry word! analogue. The quantitative method revealed that the analogues described in NEDS correlate with the hyponyms and hyperonyms in RuWordNet which contributes to the study of near–synonymy. The qualitative method (observation and linguistic interpretation) was used to analyze pairs entry word! analogue which showed the longest distance; such words were 52 adjectives and15 verbs. First, the meanings of entry words and analogues were checked against two Russian language thesauri, then, their representation in the tree graph of RuWordNet was traced. The analysis revealed inaccuracies concerning the similarity between certainwords. The recommendations for further improvement of RuWordNet were given.
Design of mechanisms with scissor linear joints for swept volume reduction

This paper addresses the optimal design of a new parallel robot, the Expteron, in which a networked scissor used as linear joint allows to reduce the swept volume of the kinematics chains. This robot is based on the Tripteron robot where the passive elbows constituted by two bars and three revolute joints are replaced by a set of networked scissors. By changing the architecture of the leg, only one working mode stands for each leg. The design is conducted on the basis of one prescribed cubic Cartesian workspace. The number of loops in the networked scissors are computed to avoid self-interference and to reduce the swept volume. A finite element analysis is made to define a preliminary stiffness model to predict the bending deformation when the mobile platform are subjected to unidirectional forces along the z-axis.
Ciblage de la cellule souche leucémique exprimant la protéine lL-1RAP : Approche d'immunothérapie anti-tumorale utilisant des lymphocytes T génétiquement modifiés pour exprimer un récepteur chimérique à l’antigène(CAR)

Nous avons produit des CART-cells et des LT-mock ont ete produits ex-vivo. L'efficacite de transduction est mesure par l'expression CD3+/CD19+ (82% en moyenne, n=S), en cytometrie en flux. L'expression proteique de CAR a ete verifiee par western blot et en cytometrie en flux attestant de son expression membranaire. Nous avons teste la fonctionnalite de la cassette suicide iCaspase9/ AP1903 sur CART-cells apres 48h de traitement a I' AP1903. Nous avons montre que plus de 90% des CART-cells entrent en apoptose (Marquage 7-AAD en cytometrie en flux). Nous avons ensuite realise des tests fonctionnels in-vitro des CART-cells contre des lignees LMC exprimant naturellement IL-lRAP ou contre des lignees transfectees pour exprimer la forme membranaire d'IL-lRAP. Apres co­culture des CART-cells en presence des cellules cibles IL-lRAP+ nous avons montre qu'ils proliferent (test CFSE), qu'ils secretent de l'interferon y et des cytokines inflammatoires. Enfin, par marquage 7-AAD, nous avons demontre la cytotoxicite des CART-cells contre les cellules ILl-RAP+. Finalement, nous avons montre l'efficacite des CART-cells in vivo, dans un modele de xenogreffe tumorales dans des souris immunodeficiences NSG greffees par la lignee K562-IL1RAP+ / Luciferase +. On constate une diminution de la masse tumorale 4 jours apres injection des CART-cells, jusqu'a disparition totale. Cette preuve de concept laisse entrevoir des perspectives therapeutiques alternatives dans le traitement de la LMC ou LAM, qui devront etre optimiser dans des modeles murins (sequence et nombres d'injection, nombres de cellules, associations avec ITKS ou autres chimiotherapies) afin de conduire un essai clinique de phase I, pour demontrer la faisabilite et la securite de l'approche pour envisager une demonstration d'efficacite chez l'homme. La securisation par la cassette suicide permet d'envisager l'utilisation des CART-cells en situation autologue ou allogenique (Donor Lymphocytes infusion, DU)
Volatility and co-movements of the equity markets in Central Europe – evidence from Poland and Hungary

This article aims at verifying if there has been a structural change in the co-movement pattern of selected Central and Eastern Europe (CEE) over the ten-year period following the financial crisis. The empirical results confirmed that such a change was observed both in the correlation and volatility levels for specific market segments, as well as in the market dynamics. These findings provide a new insight into understanding the shock resilience, which consequently can supplement a wider assessment of the systemic risk in the financial markets. The key results point towards a decreased uncertainty in estimated correlation levels during the post-crisis period. Such findings are consistent with the hypothesis that intermarket linkages are currently better reflected in market prices when compared to the pre-crisis period. While this is clearly a positive signal for future system stability, it also evidences that the widely used GARCH and DCC specifications turn to be relatively narrow and therefore greater caution is highly recommended when interpreting estimation results.
Network Embedding For Link Prediction in Bipartite Networks

Many social networks have a bipartite nature. Link prediction in social networks has been the focus of interest for many researchers recently. Network embedding, which maps each node in the network to a low-dimensional feature vector is used to solve many problems. The aim of this study is to investigate how network embedding enhance the link prediction performance in bipartite networks. A network embedding and a supervised learning based link prediction model has been presented for bipartite networks. The input of the supervised learning model is learned embedding vectors of node pairs obtained from network embedding method. The target feature of prediction is a binary label indicating the existence or absence of a link between these node pairs. Ensemble learning algorithms have been applied for supervised link prediction. The experiments performed on two bipartite social networks built from public datasets led promising results with 0.939 and 0.974 AUC values. Random Forest models trained with embedding vectors obtained from BiNE method achieved the highest performances.
Exploring the Privacy Bound for Differential Privacy: From Theory to Practice

Data privacy has attracted signiﬁcant interests in both database theory and security communities in the past few decades. Di ﬀ erential privacy has emerged as a new paradigm for rigorous privacy protection regardless of adversaries prior knowledge. However, the meaning of privacy bound (cid:15) and how to select an appropriate (cid:15) may still be unclear to the general data owners. More recently, some approaches have been proposed to derive the upper bounds of (cid:15) for speciﬁed privacy risks. Unfortunately, these upper bounds su ﬀ er from some deﬁciencies (e.g., the bound relies on the data size, or might be too large), which greatly limits their applicability. To remedy this problem, we propose a novel approach that converts the privacy bound in di ﬀ erential privacy (cid:15) to privacy risks understandable to generic users, and present an in-depth theoretical analysis for it. Finally, we have conducted experiments to demonstrate the e ﬀ ectiveness of our model.
Gamma-Ray Burst Optical Afterglows with Two-component Jets: Polarization Evolution Revisited

Gamma-ray bursts have been widely argued to originate from binary compact object mergers or core collapse of massive stars. Jets from these systems may have two components: an inner, narrow sub-jet and an outer, wider sub-jet. Such a jet subsequently interacts with its ambient gas, leading to a reverse shock (RS) and a forward shock. The magnetic field in the narrow sub-jet is very likely to be mixed by an ordered component and a random component during the afterglow phase. In this paper, we calculate light curves and polarization evolution of optical afterglows with this mixed magnetic field in the RS region of the narrow sub-jet in a two-component jet model. The resultant light curve has two peaks: an early peak arising from the narrow sub-jet and a late-time rebrightening due to the wider sub-jet. We find the polarization degree (PD) evolution under such a mixed magnetic field confined in the shock plane is very similar to that under the purely ordered magnetic field condition. The two-dimensional “mixed” magnetic fields confined in the shock plane are essentially the ordered magnetic fields only with different configurations. The position angle (PA) of the two-component jet can change gradually or abruptly by 90°. In particular, an abrupt 90° change of the PA occurs when the PD changes from its decline phase to the rise phase.
Geophysical Inversion for Mineral Exploration : a Decade of Progress in Theory and Practice

Developments in instrumentation, data collection, computer performance, and visualisation have been catalysts for significant advances in modelling and inversion of geophysical data. Forward modelling, which is fundamental to intuitive geological understanding and practical inversion methods, has progressed from representations using simple 3D models to whole earth models using voxels and discrete surfaces. Inversion has achieved widespread acceptance as a valid interpretation tool and major progress has been made by integrating geological models as constraints for both voxel and multi-body parametric methods. As a consequence, potential field, IP and electromagnetic inversion methods have become an essential part of most mineral exploration programs. In this paper we summarize some of the progress made over the last decade for each of these data types. Inversion applications are divided into three categories: (a) Type I (discrete body), (b) Type II (pure property) and (c) Type III (lithologic). Potential field inversions are the most advanced and thus most commonly used. 3D DC resistivity and IP inversions are becoming more prevalent. 3D EM inversions, in both time and frequency domains, are just emerging. Inversion examples are drawn from a number of groups and over different geological targets. However, we make extensive use of the geophysical data set from San Nicolas, since 3D inversions of all data types have been carried out there. The paper is essentially non-mathematical but we have incorporated some generic detail regarding how the inversions are carried out and the computations needed. We conclude the paper with our views of where research will be focused for the next decade and also provide our assessment of the challenges that the industry must address to make maximum use of inversion methodologies.

INFLUENCE OF NITROGEN AND ORGANIC FERTILIZATION ON GROWTH, YIELD AND QUALITY OF SUGAR BEET GROWN IN CALCAREOUS SOIL.

The present investigation was carried out during the growth season of 2011-2012 at Nobaria Sugar and Refining Company, El-Bohera Governorate to evaluate the influence of N- fertilization on yield and quality of sugar beet grown in calcareous soil. Split plot design with 3 replicates with 8 treatments, four rates of nitrogen fertilizer were spread in the main plot, while the sub plots were assigned for the two organic fertilizers. The result obtained showed significant increase in shoot fresh weight, root fresh weight, root length, root yield and sugar yield in plants with increasing fertilization up to 350 kg N/fed. Organic fertilization by farmyard manure (FYM) and poultry manure (PM) was tested. The yield of these attributes of sugar beet was increased but the estimating effect was higher for PM than FYM. The technological characters of sugar beet (Sugar percentage, Purity, K, Na and Alfa-amino-N) rose with increasing N fertilization rate with application of PM or FYM.Under conditions of the present work, supplying sugar beet with 350 kg N/fed with FYM or PM resulted in the highest root and sugar yields/fed.
Solar Radiation in Tidal Flat

The Ariake Sea, which is located in the north-western part of Kyushu Island, is one of the best-known semi-closed shallow seas in Japan. Many rivers flow into the eastern coast area of the Ariake Sea and carry 4.4 x 108 kg of sediments per year (Azad et al. 2005). Coarse sediments accumulate in the eastern coast, and fine grains brought by the residual current accumulate in the bay head to form vast tidal flats with fine sediments (Kato and Seguchi 2001). The vast tidal flat mud of the Ariake Sea, which is almost 40% of the total tidal flat area of Japan, is famous for its rich fishery products and Porphyra sp. (sea weed) cultivation. Different types of shells like Sinonovacula constricta, Atrina pectinata and Crassostrea gigas are important creatures in the Ariake tidal mud. However, a dramatic decrease in the catch of these shells is observed in the tidal flat area. From Fig. 1 it is seen that the catch of Crassostrea gigas usually living in the near surface mud, dropped from 7.99 x 105 kg in 1976 to only 1.26 x 105 kg in 1999; that of Atrina pectinata, living in the upper 0.10-0.15 m of the mud, declined from 1.3395 x 107 kg in 1976 to 7.9 x 104 kg in 1999, and the situation in the case of Sinonovacula constricta, living in the depth of 0-0.7 m of the mud, was even worse: 1.7 x 105 kg catch in 1976 dropped to practically nil by 1992.
Wi-Fi Security Attacks Auditor for Wi-Fi Protected Access and Wi-Fi Protected Access-2 Protocol

Wi-Fi (Wireless-Fidelity) is one of the popular wireless technology in which radio waves are used to transmit data. Wi-Fi is used extensively today and can be find every places like restaurants, railway stations, airports etc. Here data is transfer wirelessly hence more security is needed to these networks. There are mainly three security protocols are developed namely 1.Wired Equivalent Privacy 2.Wireless Protected Access 3. Wireless Protected Access-2.WEP is basic protocol and least secure among three. In this paper we will study remaining protocol in brief. But for their use, user have to write particular set of commands every time . Hence the aim of paper is to develop a software which will automate different attack. So that user can check the status of the network without doing much effort. Here we are using python language for our programming on backtrack-4 operating system. The program will first find out the encryption protocol and according to that it will perform different attack. It will generate one text file which contains key. Thus we can check the vulnerabilities of our network against different attacks and user can do modifications to enhance security. Keywords—WEP,WPA,WPA-2, security Attacks,python,Wi-Fi auditor,backtrack,aircrack-ng
Historical Perspectives and the Emergence of the Sustainability Concept in Organizations

This paper commences by examining historical perspectives and the emergence of the concept in organizations. It is important to analyze the historical background of sustainability in order to document the theoretical approaches that have shaped it and continue to inform development in sustainability practices among organizations. Furthermore, the thin line between CS or sustainability and CSR has been noted, with the latter seemingly contributing a small part of the holistic concept of sustainable development. It also provides a theoretical construction and conceptualization of sustainability, as well as detailed perspectives on its importance and major drivers, both in the past and in the modern context. Finally, the paper documents the relevant models that explain the concept.
Synthesis and Characterization of Copper Nanoparticles by Bis-(Acetylacetonato)-Copper (II) Using Nonionic Surfactants and the Effect of Their Structures on Nanoparticles Size and Yield

Between all precursors of copper complex, bis-(acetylacetonato)-copper (II) and bis-oxalate copper (II) with very close structures are two of the best representatives for copper nanoparticles synthesis. In this research, only bis-(acetylacetonato)-copper (II) in presence of some effective non-ionic surfactants such as Triton X-100, Dodecylamine, Tween 80 and also triphenylphosphine as a reducing agent via thermal decomposition process was used for copper nanopaticles synthesis. Two shif-base E19 and E22 complexes were also used for the investigation of these kinds of shif-base complexes capabilities by this method as precursors and all results were compared with each other. Between all surfactants, Triton X-100 gave the best yield with the largest grains. The techniques used for characterization of copper nanoparticles were TEM, EDX, FT-IR and XRD. TG-DTA and CV were used for characterization of bis-(acetylacetonato)-copper (II) complex.
Evaluation of Software-Based Fault-Tolerant Techniques on Embedded OS ’ s Components

Software-based fault-tolerant techniques at the operating system level are an effective way to enhance the reliability of safety-critical embedded applications. This paper provides an analysis and comparison of five well-known recovery techniques, i.e., micro rebooting, recovery block, N-Version Programming (NVP), micro extension, and transactional extension for an embedded operating system’s components, from performance point of view. These techniques are applied without any modification on the main architecture of the operating system. The techniques are implemented on a virtual ARM Integrator board which is emulated by the QEMU software (2.0.0) under the control of Embedded Linux operating system (3.9.0). The totals of 5000 software errors are ignited using a simulation environment. The results show that the recovery time overhead varies between 0.17% and 0.67%, and the performance overhead varies between 5.81% and 218.65% depending on the techniques. Keywords-embedded operating system; fault tolerant; recovery; performance.
