Abstract:
A change in teaching delivery at a large Australian university, from two semesters to three trimesters, was the occasion for using more formative assessment in a core first-year mathematics unit. This study compared evidence about learning outcomes for two cohorts in adjacent years. Cohort 1 was the last taught over a semester, and Cohort 2 the first taught over a trimester. There was no change in overall workload, and no change in the unit's total teaching hours, syllabus or materials. Assessments were changed for class tests during the teaching period by giving Cohort 2 access to unlimited practice and computer-assisted feedback on the questions in the test database, followed by doing the tests under examination conditions. For Cohort 2, a written assignment was also added, focused on giving a clear solution to a mathematics problem, and awareness of the need for appropriate evidence, both background and internal to the problem. Learning outcomes were compared using closely comparable tasks from the final examinations, and examining students' answers in the examination scripts. Outcomes were assessed by a method derived from the solo taxonomy, which afforded a common scale to measure the quality of learning outcomes observable in final examination scripts. Results on separate tasks, plus those for a composite score, favoured Cohort 2. The effect size for the composite score was 0.457. This indicates that the unlimited practice with computer feedback for class tests, and the writing assignment, were functioning as intended in promoting learning with understanding. References S.

Abstract:
In this paper, we prove a generalization of a correspondence between holomorphic Jacobi cusp forms of higher degree (matrix index) and elliptic cusp forms obtained by K. Bringmann [Lifting maps from a vector space of Jacobi cusp forms to a subspace of elliptic modular forms, Math. Z.253 (2006) 735–752], for forms of higher levels (for congruence subgroups). To achieve this, we make use of the method adopted by M. Manickam and the first author in Sec. 3 of [On Shimura, Shintani and Eichler–Zagier correspondences, Trans. Amer. Math. Soc.352 (2000) 2601–2617], who obtained similar correspondence in the degree one case. We also derive a similar correspondence in the case of skew-holomorphic Jacobi forms (matrix index and for congruence subgroups). Such results in the degree one case (for the full group) were obtained by N.-P. Skoruppa [Developments in the theory of Jacobi forms, in Automorphic Functions and Their Applications, Khabarovsk, 1988 (Acad. Sci. USSR, Inst. Appl. Math., Khabarovsk, 1990), pp. 168–185; Binary quadratic forms and the Fourier coefficients of elliptic and Jacobi modular forms, J. Reine Angew. Math.411 (1990) 66–95] and by M. Manickam [Newforms of half-integral weight and some problems on modular forms, Ph.D. thesis, University of Madras (1989)].

Abstract:
The virtual element method is an extension of the finite element method on polygonal meshes. The virtual element basis functions are generally unknown inside an element and suitable projections of the basis functions onto polynomial spaces are used to construct the elemental stiffness and mass matrices. We present a gradient recovery method based on an oblique projection, where the gradient of the L2-polynomial projection of a solution is projected onto a virtual element space. This results in a computationally efficient numerical method. We present numerical results computing the gradients on different polygonal meshes to demonstrate the flexibility of the method.

Abstract:
Charts displayed on mobile devices was verified in comparison to standardized ETDRS charts. Such method of visual acuity assessment is characterized by stabile brightness and contrast. Moreover the ability to dynamically display random optotypes eliminates the problem of memorizing the contents of charts, making measurements more reliable. Our tests showed that the VA measured with mobile device and the VA tested using standardized printed charts are not significantly different. Full Text: PDF ReferencesB.

Abstract:
A study on the adsorption characteristic of Iron onto Poly[eugenol-co-(divinyl benzene)] (EDVB) from aqueous solution has been conducted. EDVB was produced and characterized by using FTIR spectroscopy. The adsorption was studied by a batch method by considering the factors affecting the adsorption such as initial metal ion concentration, adsorption selectivity, and mechanism of adsorption using a sequential desorption method. The adsorption of Iron onto EDVB followed a pseudo-2 order kinetics model with the rate constant of 0,144 L2 mmol-1 min-1. The adsorption isotherm was studied with Tempkin, Langmuir and Freundlich models. The adsorption capacity (Qmax) obtained by Langmuir isotherms was 250mg.L-1 while the equilibrium value was 0.8 Lmg-1. A competitive adsorption study showed that EDVB is adsorbed selectively towards Iron rather than Chromium, Coppers and Cadmium ions. The interaction type of Iron onto EDVB was determined by a sequential desorption.Keywords: Polyeugenol; divinyl benzene (DVB); adsorption; Iron; FeReferencesAbasi, C. Y.; Abia, A.A.; Igwe, J.C.

Abstract:
The impact of agricultural intensification on soil degradation now is occurring in tropical countries. The objective of this study was to determine the effect of long-term tillage and N fertilization on soil properties and crop yields in corn-soybean rotation. This long-term study which initiated since 1987 was carried out on a Typic Fragiudult soil at Politeknik Negeri Lampung, Sumatra (105o13’45.5"-105o13’48.0"E, 05o21’19.6"-05o21’19.7"S) in 2010 and 2011. A factorial experiment was arranged in a randomized block design with four replications. The first factor was tillage system namely intensive tillage (IT) and conservation tillage (CT) which consist of minimum tillage (MT) and no-tillage (NT); while the second factor was N fertilization with rates of 0, 100 and 200 kg N ha-1 applied for corn, and 0, 25, and 50 kg N ha-1 for soybean. The results showed that bulk density and soil strength at upper layer after 24 years of cropping were similar among treatments, but the soil strength under IT at 50-60 cm depth was 28.2% higher (p<0.05) than NT. Soil moisture and temperature under CT at 0-5 cm depth were respectively 38.1% and 4.5% higher (p<0.05) than IT. High N rate decreased soil pH at 0-20 cm depth as much as 10%, but increased total soil N at 0-5 cm depth as much as 19% (p<0.05). At 0-10 cm depth, MT with no N had highest exchangeable K, while IT with medium N rate had the lowest (p<0.05). At 0-5 cm depth, MT with no N had highest exchangeable Ca, but it had the lowest (p<0.05) if combined with higher N rate. Microbial biomass C throughout the growing season for NT was consistently highest and it was 14.4% higher (p<0.05) than IT. Compared to IT, Ap horizon of CT after 24 years of cropping was deeper, with larger soil structure and more abundance macro pores. Soybean and corn yields for long-term CT were 64.3% and 31.8% higher (p<0.05) than IT, respectively. Corn yield for long-term N with rate of 100 kg N ha-1 was 36.4% higher (p<0.05) than with no N.Keywords: Conservation tillage, crop yields, N fertilization, soil properties[How to Cite: Utomo M, IS Banuwa, H Buchari, Y Anggraini and Berthiria. 2013.Long-term Tillage and Nitrogen Fertilization Effects on Soil Properties and Crop Yields.

Abstract:
Sclerosant foam, a mixture of a surfactant liquid and air, is injected directly into varicose veins as a treatment that causes the vein to collapse. This investigation develops a model that will allow the medical specialist to visualise how the sclerosant foam will interact with the blood and behave within the vein. The process is simulated using a multiphase computational fluid dynamics model with the sclerosant foam considered as a two-phase non-Newtonian power law viscosity liquid. The governing multiphase equations are solved using an Eulerian⁠–⁠Eulerian approach coupled with a population balance model to predict the bubble size distribution within the flow field. The computational results demonstrate similar flow characteristics and flow features to an available set of experimental results. The model predicts the mixing layers between the sclerosant foam and the ambient fluid, and the sclerosant liquid and the ambient fluid, as well as the sclerosant liquid coverage on the vein wall and the bubble size distribution within the vein. These quantities are of interest to medical specialists allowing them to assess the treatment feasibility and safety before treating the patients. References S. Ali Mirjalili, J. C. Muirhead, and M.

Abstract:
The discrete thin plate spline smoother fits smooth surfaces to large data sets efficiently. It combines the favourable properties of the finite element surface fitting and thin plate splines. The efficiency of its finite element grid is improved by adaptive refinement, which adapts the precision of the solution. It reduces computational costs by refining only in sensitive regions, which are identified using error indicators. While many error indicators have been developed for the finite element method, they may not work for the discrete smoother. In this article we show three error indicators adapted from the finite element method for the discrete smoother. A numerical experiment is provided to evaluate their performance in producing efficient finite element grids. References F. L. Bookstein.

Abstract:
Cette thèse est constituée de l'édition de la traduction en français et des commentaires historiques, thématique et linguistique du texte du qâdî d'Azemmour al-Sanhâjî (m en795/1392) intitulé Kanz al-asrâr wa lawâqih al-afkâr « le Trésor des secrets et des idées fécondes ». Elle apporte une découverte de cet auteur presque totalement méconnue de nos jours aussi bien dans le monde Arabe que dans les milieux orientalistes. Il s'agit pourtant d'une personnalité à la fois par sa vaste culture, par sa capacité d'organiser les connaissances, et par l'originalité de ses réflexions non dénuées de finesse et de hauteur spirituelle. Elle donne également l'occasion d'élargir les connaissances dans le domaine des encyclopédies du monde invisible. Enfin cette recherche permet une meilleure compréhension des mondes des transmissions des données traditionnelles (traditions prophétiques, récits, informations de type scientifiques) à cette époque au Maghreb et met l'accent entre autres, sur l'importance d'autres textes, que l'on commence à peine à mettre en lumière, comme le Tafsîr de Makkî
This thesis is constituted with the edition, the French translation and the historic, thematic and linguistic commentaries of qâdî d'Azemmour al-Sanhâjî‘s text, entitled Kanz al-asrâr wa lawâqih al-afkâr (Treasure of secrets and fertile ideas). It provides a discovery of this nearly completely unknown author in Arabic world as in orientalist spheres. He has nevertheless a distinguished personality, thanks to his wide culture, his ability to organise learnings and to the originality of his smart and high thought. It gives also the opportunity to extend the knowledge in the Middle-Age encyclopedia's field because it can be defined as an invisible world's encyclopedia. Finally, this research permits a better understanding of how traditional dates (prophetic traditions, narrations, and scientific information) are transmitted in Maghreb during this period. It also points the importance of other representative texts, as the Makkî's Tafsîr, which is barely studied

Abstract:
L’ESM, Epistémo-Socio-Marketing, est une forme de Marketing dont il reprend l’ensemble des concepts en y intégrant les apports de l’approche épistémologique. L’ESM, permet de réaliser une lecture de la dimension sociale sans pour autant la couper de ses origines et de ses racines et sans dénaturer ses valeurs, mais de plus, en augmente sa portée en montrant sa dimension économique. L’ESM, permet également de réaliser une lecture de l’approche Marketing en la rattachant à ce qui semble ses véritables origines, en mettant à jour ses valeurs, en augmentant sa portée notamment sociale. L’ESM, après avoir été positionné par rapport à la dimension sociale et économique, permet enfin une meilleure complémentarité entre le secteur Social et le secteur marchand et aux managers de structures intervenant dans le secteur Social et marchand de mieux articuler performance sociale et performance économique
The ESM, Epistémo-Socio-Marketing, is a form of Marketing of which it takes again the whole of the concepts by integrating the contributions of the epistemological approach there. The ESM, makes it possible to carry out a reading of social dimension without cutting it its origins and of its roots and without denaturing its values, but moreover, its range increases some by showing its economic dimension. The ESM, also makes it possible to carry out a reading of the Marketing approach by attaching it to what seems its true origins, by updating its values, by increasing its in particular social range. The ESM, after being positioned compared to social and economic dimension, allows finally a better complementarity between the Social sector and the sector commercial and with the managers of structures intervening in the Social sector and commercial to better articulate social performance and economic performance

Abstract:
Au tournant des années 2000 émerge au sein de l’Union européenne (UE) le débat sur la responsabilité sociale des entreprises (RSE), inscrite à l’agenda politique à compter du Conseil européen de Lisbonne de mars 2000. La définition qu’a donnée la Commission de la RSE dans son livre vert de juillet 2001 est la suivante : « l’intégration volontaire par les entreprises de préoccupations sociales et environnementales à leurs activités commerciales et leurs relations avec les parties prenantes ». Un processus de consultation est lancé, la perspective d’un cadre juridique est envisagée, un Forum des parties prenantes est instauré. La thèse propose une analyse de la façon dont l’UE et ses institutions se sont saisies du phénomène de RSE. Elle identifie les différents éléments du contexte qui ont présidé à l’action européenne en la matière et rappelle quels ont été les grands axes de cette action. Sont également présentés les acquis du droit communautaire dans les domaines relatifs à la RSE et les limites que l’action a rencontrées ; est ainsi expliqué en quoi les réflexions sur la nouvelle gouvernance européenne et l’évolution des méthodes d’action de l’UE ont contribué à l’enlisement progressif du débat sur l’instauration d’un cadre juridique pour la RSE
At the turn of the 2000s emerged within the European Union (EU) a debate on corporate social responsability (CSR), placed on the political agenda after the Lisbon European Council of March 2000. The definition of CSR given by the Commission in the Green Paper published in July 2001 is as follows : "a concept whereby companies integrate social and environmental concerns in their business operations and in their interactions with their stakeholders on a voluntary basis". A consultation process is launched, the prospect of a legal framework is considered, a stakeholder forum is established. The thesis proposes an analysis of how the UE and its institutions have captured the phenomenon of CSR. It identifies the various elements of context which led to European action in the matter and said what the main thrusts of this action were. Are also presented the achievements of European law in areas related to CSR and the limits that the action has encountered ; it is explained how reflections on the new European governance and the changing methods of EU action have contributed to the gradual sinking of the debate on establishing a legal framework for CSR

Abstract:
Le 17 juin 1789, tout était à faire : l'abandon annoncé du système fiscal de la monarchie absolue laissait un vide à combler. Tout semblait possible, tous les espoirs pouvaient être réalisés. L'Assemblée constituante tenta de mettre en place un système fiscal répondant aux attentes des cahiers de doléances. Il importait au législateur de créer une fiscalité uniforme, respectueuse du principe d'égalité. Néanmoins, l'application dans les départements, et notamment dans celui de l'Hérault, rencontra de nombreuses difficultés : des lois imprécises qui réduirent la portée du principe d'égalité, des contextes économiques, politiques et sociaux défavorables et des administrations locales insatisfaites par la baisse des impôts. De 1791 à l'an III, les recouvrements accumulèrent des retards, ne permettant pas une pleine efficacité du nouveau système fiscal. Avec le Directoire, s'est ouverte une nouvelle phase : l'aspect économique des impôts prévalut. Il n'était plus question d'établir la stricte proportionnalité mais de mettre l'accent sur le rendement. Les ébauches de réformes commencées dès l'an IV ont été achevées sous le Consulat. Durant toute la période, c'était au niveau local qu'il fallait rechercher les tentatives les plus franches et les plus répétées pour concrétiser les idéaux fiscaux de 1789. Dans le département de l'Hérault, contribuables et administrateurs locaux ont été vigilants à concilier les exigences des gouvernements avec la proportionnalité et la baisse des contingents
June 17, 1789, everything had yet to be done: the announced abandonment of the Absolute Monarchy's tax system left a gap to be filled. Everything seemed possible ; every hope could be carried out. The National Constituent Assembly attempted to set up a tax system responding to the expectations stated in the registers of grievances. The legislator's priority was to create a uniform taxation, respectful of the Equality principle. Nevertheless, the implementation of this tax system in the departments, and especially in Hérault, encountered many difficulties : laws were too vague and diminished the impact of the Equality principle ; the economic, political and social contexts were unfavourable; local governments were dissatisfied by the lowering of taxes. From 1791 to Year III, delays built up in the collection of taxes, preventing the full effectiveness of the new tax system. With the Directory, a new phase opened : The economic aspect of taxes prevailed. Establishing strict proportionality was no longer foreseen and instead stress was put on yield. The reforms' outlines started in Year IV were completed under the Consulate. During all that period, the most honest and repeated attempts to make concrete the tax ideals of 1789 have to be searched at a local level. In the department of Hérault, taxpayers and local administrators were careful to match the requirements of the governments with proportionality and the decrease of quotas

Abstract:
This volume comprises a selection of papers delivered at the symposium “The Word Illuminated: Form and Function of Qurʾanic Manuscripts” held at the Arthur M. Sackler Gallery from 1 to 3 December 2016 and organized in conjunction with the exhibition The Art of the Qurʾan: Treasures from the Museum of Turkish and Islamic Arts. Authors investigate the materiality of luxury Qurʾans, from the lavish use of costly materials such as gold and parchment, the development of special scripts, and intricate illuminated designs to the meticulously tooled bindings. In addition to examining the physical features of Qurʾanic volumes, the authors put the manuscripts in their artistic, historic, and religious contexts to understand more fully the transformation of these works into potent symbols of piety and political and religious authority and into instruments of legitimacy. Over the centuries, many of the Qurʾans were offered as diplomatic gifts or taken as booty and endowed to mosques, tombs, and other religious complexes to perpetuate and transmit their exceptional baraka (divine blessing). As the Qurʾans changed ownership, they also acquired a complex and layered afterlife, which has further enriched their identity well into the present.

This volume presents a summary of the latest academic conference on urban and regional planning, which took place at the Technical University Berlin in March 2019. The conference addressed current demands in urban development with regard to the creation of building land and its legal requirements. In the past years, we have seen a growing demand to establish building land, especially for the provision of housing. Here, unplanned inner-areas have a particular importance. Through procedural simplifications, German legislators are trying to incentivise municipalities to set up, modify or complement land-use plans. Delimitation problems between the planning instruments themselves and their scope are currently a problem for both investors and municipalities. These conference proceedings are intended to help practitioners who are dealing with the new regulations. With contributions by Prof. Dr. Michael Krautzberger, Prof. Dr. Alexander Schink, Dr.-Ing.

Abstract:
Horseradish roots, due to the content of many valuable nutrients and substances with healing and pro-health properties, are used more and more in medicine, food industry and cosmetics. In Poland, the cultivation of horseradish is considered minor crops. In addition, its limited size causes horseradish producers to encounter a number of unresolved agrotechnical problems. Infectious diseases developing on the leaves and roots during the long growing season reduce the size and quality of root crops. The small range of protection products intended for use in the cultivation of horseradish generates further serious environmental problems (immunization of pathogens, low effectiveness, deterioration of the quality of raw materials intended for industry, destruction of beneficial organisms and biodiversity). In order to meet the problems encountered by horseradish producers and taking into account the lack of data on: yielding, occurrence of infectious diseases and the possibility of combating them with methods alternative to chemical ones in the years 2012–2015, rigorous experiments have been carried out. The paper compares the impact of chemical protection and its reduced variants with biological protection on: total yield of horseradish roots and its structure. The intensification of infectious diseases on horseradish leaves and roots was analyzed extensively. Correlations were examined between individual disease entities and total yield and separated root fractions. A very important and innovative part of the work was to learn about the microbial communities involved in the epidemiology of Verticillium wilt of horseradish roots. The effect was examined of treatment of horseradish cuttings with a biological preparation (Pythium oligandrum), a chemical preparation (thiophanate-methyl), and the Kelpak SL biostimulator (auxins and cytokinins from the Ecklonia maxima algae) on the quantitative and qualitative changes occurring in the communities of these microorganisms. The affiliation of species to groups of frequencies was arranged hierarchically, and the biodiversity of these communities was expressed by the following indicators: Simpson index, Shannon–Wiener index, Shannon evenness index and species richness index. Correlations were assessed between the number of communities, indicators of their biodiversity and intensification of Verticillium wilt of horseradish roots. It was shown that the total yield of horseradish roots was on average 126 dt · ha–1. Within its structure, the main root was 56%, whereas the fraction of lateral roots (cuttings) with a length of more than 20 cm accounted for 26%, and those shorter than 20 cm for 12%, with unprofitable yield (waste) of 6%. In the years with higher humidity, the total root yield was higher than in the dry seasons by around 51 dt · ha–1 on average. On the other hand, the applied protection treatments significantly increased the total yield of horseradish roots from 4,6 to 45,3 dt · ha–1 and the share of fractions of more than 30 cm therein. Higher yielding effects were obtained in variants with a reduced amount of foliar application of fungicides at the expense of introducing biopreparations and biostimulators (R1, R2, R3) and in chemical protection (Ch) than in biological protection (B1, B2) and with the limitation of treatments only to the treatment of cuttings. The largest increments can be expected after treating the seedlings with Topsin M 500 SC and spraying the leaves: 1 × Amistar Opti 480 SC, 1 × Polyversum WP, 1 × Timorex Gold 24 EC and three times with biostimulators (2 × Kelpak SL + 1 × Tytanit). In the perspective of the increasing water deficit, among the biological protection methods, the (B2) variant with the treatment of seedlings with auxins and cytokinins contained in the E. maxima algae extract is more recommended than (B1) involving the use of P. oligandrum spores. White rust was the biggest threat on horseradish plantations, whereas the following occurred to a lesser extent: Phoma leaf spot, Cylindrosporium disease, Alternaria black spot and Verticillium wilt. In turn, on the surface of the roots it was dry root rot and inside – Verticillium wilt of horseradish roots. The best health of the leaves and roots was ensured by full chemical protection (cuttings treatment + 6 foliar applications). A similar effect of protection against Albugo candida and Pyrenopeziza brassicae was achieved in the case of reduced chemical protection to one foliar treatment with synthetic fungicide, two treatments with biological preparations (Polyversum WP and Timorex Gold 24 EC) and three treatments with biostimulators (2 × Kelpak SL, 1 × Tytanit). On the other hand, the level of limitation of root diseases comparable with chemical protection was ensured by its reduced variants R3 and R2, and in the case of dry root rot, also both variants of biological protection. In the dry years, over 60% of the roots showed symptoms of Verticillium wilt, and its main culprits are Verticillium dahliae (37.4%), Globisporangium irregulare (7.2%), Ilyonectria destructans (7.0%), Fusarium acuminatum (6.7%), Rhizoctonia solani (6.0%), Epicoccum nigrum (5.4%), Alternaria brassicae (5.17%). The Kelpak SL biostimulator and the Polyversum WP biological preparation contributed to the increased biodiversity of microbial communities associated with Verticillium wilt of horseradish roots. In turn, along with its increase, the intensification of the disease symptoms decreased. There was a significant correlation between the richness of species in the communities of microbial isolates and the intensification of Verticillium wilt of horseradish roots. Each additional species of microorganism contributed to the reduction of disease intensification by 1,19%.

Abstract:
AbstractThere are severe environmental and ecological issues once we evaluate the architecture industry with LCA (Life Cycle Assessment), such as emission of CO2 caused by necessary high temperature for producing cement and significant amounts of Construction Demolition Waste (CDW) in deteriorated and obsolete buildings. One of the ways to solve these problems is Bio-Material. CELLULOSE and CHITON is the 1st and 2nd abundant substance in nature (Duro-Royo, J.: Aguahoja_Programmable Water-based Biocomposites for Digital Design and Fabrication across Scales. MIT, pp. 1–3 (2019)), which means significantly potential for architectural dimension production. Meanwhile, renewability and biodegradability make it more conducive to the current problem of construction pollution. The purpose of this study is to explore Cellulose Based Biomaterial and bring it into architectural scale additive manufacture that engages with performance in the material development, with respect to time of solidification and control of shrinkage, as well as offering mechanical strength. At present, the experiments have proved the possibility of developing a cellulose-chitosan- based composite into 3D-Printing Construction Material (Sanandiya, N.D., Vijay, Y., Dimopoulou, M., Dritsas, S., Fernandez, J.G.: Large-scale additive manufacturing with bioinspired cellulosic materials. Sci. Rep. 8(1), 1–5 (2018)). Moreover, The research shows that the characteristics (Such as waterproof, bending, compression, tensile, transparency) of the composite can be enhanced by different additives (such as xanthan gum, paper fiber, flour), which means it can be customized into various architectural components based on Performance Directional Optimization. This solution has a positive effect on environmental impact reduction and is of great significance in putting the architectural construction industry into a more environment-friendly and smart state.

Abstract:
The identification of efficient techniques for the fabrication of Ultra High Temperature Ceramics (UHTCs) is very crucial in view of their rapid and wider development. Along these lines, the use of the self-propagating high-temperature synthesis (SHS) technique in combination with the SPS technology is examined in this chapter for the obtainment of fully dense MB2-SiC and MB2-MC-SiC (M=Zr, Hf, Ta) ceramics. The starting reactants are first processed by SHS to successfully form the desired composites. The resulting powders are subsequently consolidated by spark-plasma sintering (SPS). Bulk products with relative densities = 96% can be obtained within 30 minutes, when the dwell temperature is 1800 °C and P=20 MPa. Hardness, fracture toughness, and oxidation resistance of the obtained dense bodies are comparable to, and in some cases superior than, those reported for analogous products synthesized using alternative routes. Possible future developments of this approach with the final purpose of obtaining whiskers/fibers reinforced UHTCs are finally discussed.

Perfectionism is a multidimensional concept and its role on psychological well-being has gained attention in recent literature. Theaim of the current study was to examinethe relationship of different dimensions of perfectionism with self-handicapping and self-compassionand to investigate their predictive roles onpsychological well-being. For this purpose, 653 volunteeredparticipants (360 females and 293 males) whose ages were between 18 and 50 (M= 24.90, SD= 7.57) were recruited from various cities in Turkey. For data collection, Multidimensional Perfectionism Scale (MPS), Self-Handicapping Scale (SHS), Self-Compassion Scale (SCS), Brief Symptom Inventory (BSI)and Satisfaction with Life Scale (SWLS)were administered. The findings indicated that self-compassion was negatively correlated with all perfectionism domains and self-handicapping. Moreover, self-handicapping was positively correlated with socially prescribed perfectionism, but negativelycorrelated withself-oriented perfectionism.The resultsof the hierarchical regression analyses revealedthat psychological symptoms were positively associated with socially prescribed perfectionism and self-handicapping, but negatively associated with self-compassion. Finally, satisfaction with life was found to be positively associated with self-oriented perfectionism and self-compassion, while negatively associated with socially prescribed perfectionism.These findings highlighted the importance of different aspectsof perfectionism regarding to psychological well-being and its related components.

Abstract:
The catalytic reduction of the alkene 1 gave the cis-fused product (not illustrated), by kinetic H₂ addition to the less congested face of the alkene. Ryan A. Shenvi of Scripps La Jolla found (J. Am. Chem. Soc. 2014, 136, 1300) conditions for stepwise HAT, con­verting 1 to the thermodynamically-favored trans-fused ketone 2. Seth B. Herzon of Yale University devised (J. Am. Chem. Soc. 2014, 136, 6884) a protocol for the reduc­tion, mediated by 4, of the double bond of a haloalkene 3 to give the saturated halide 5. The Shenvi conditions also reduced a haloalkene to the saturated halide. Daniel J. Weix of the University of Rochester and Patrick L. Holland, also of Yale University, established (J. Am. Chem. Soc. 2014, 136, 945) conditions for the kinetic isomerization of a terminal alkene 6 to the Z internal alkene 7. Christoforos G. Kokotos of the University of Athens showed (J. Org. Chem. 2014, 79, 4270) that the ketone 9, used catalytically, markedly accelerated the Payne epoxidation of 8 to 10. Note that Helena M. C. Ferraz of the Universidade of São Paulo reported (Tetrahedron Lett. 2000, 41, 5021) several years ago that alkene epoxidation was also easily carried out with DMDO generated in situ from acetone and oxone. Theodore A. Betley of Harvard University prepared (Chem. Sci. 2014, 5, 1526) the allylic amine 12 by reacting the alkene 11 with 1-azidoadamantane in the presence of an iron catalyst. Rodney A. Fernandes of the Indian Institute of Technology Bombay developed (J. Org. Chem. 2014, 79, 5787) efficient conditions for the Wacker oxida­tion of a terminal alkene 6 to the methyl ketone 13. Yong-Qiang Wang of Northwest University oxidized (Org. Lett. 2014, 16, 1610) the alkene 6 to the enone 14. Peili Teo of the National University of Singapore devised (Chem. Commun. 2014, 50, 2608) conditions for the Markovnikov hydration of the alkene 6 to the alcohol 15. Internal alkenes were inert under these conditions, but Yoshikazo Kitano of the Tokyo University of Agriculture and Technology effected (Synthesis 2014, 46, 1455) the Markovnikov amination (not illustrated) of more highly substituted alkenes.

Abstract:
Pickering emulsions have garnered great interest in food science lately. These systems are characterized by the use of colloidal particles as physical stabilizers, that strongly anchor at the oil-water interface, instead of conventional emulsifiers. Many biobased particles have recently been identified as useful for this application, which holds potential for revolutionizing the field of food emulsion formulation [1,2]. However, although the potential in terms of physical stabilization of oil-in-water (O/W) emulsions has been thoroughly explored in the past years, how such emulsions may resist lipid oxidation, and whether particles could also be used to protect labile polyunsaturated lipids against oxidation is still questionable. This presentation aims at shedding light on this question by combining a review of the different types of food-compatible particles that have been recognized as useful to form Pickering emulsions, discussing examples of mitigation of lipid oxidation in such emulsions [3,4], and finally reflecting on the desired properties and possible targeted design of particles to achieve dual physical and oxidative stabilization of emulsions [5].[1] Berton-Carabin, C., & Schroën, K.

Abstract:
Current Nuclear Power Plants (NPPs) equipped with water-cooled reactors (the vast majority of all NPPs) have relatively low thermal efficiencies within the range of 30–36% compared to those of modern advanced thermal power plants (SuperCritical Pressure (SCP) coal-fired — up to 55% thermal efficiency and combined cycle — up to 62%). Therefore, next generation reactors / NPPs should have higher thermal efficiencies close to those of current thermal power plants. Around 60 years ago thermal-power industry has moved from subcritical pressures to SCPs with the major objective to increase thermal efficiency. Based on this proven in power industry experience it was proposed to design SuperCritical Water-cooled Reactors (SCWRs), which are one of the six Generation-IV nuclear-reactor concepts under development in selected countries. These days, there are discussions on developing even Small Modular Reactors (SMRs) of SCPs. In spite of a large number of experiments in long bare tubes (pipes) cooled with SCW, developing SCWR concepts requires experimental data in bundle geometries cooled with SCW, which are usually shorter and will have smaller diameters. However, such experiments are extremely complicated and expensive plus each bundle geometry will have a unique Heat-Transfer (HT) characteristics due to various bundle designs. Therefore, as a preliminary and a universal approach — experiments in bare tube of shorter heated lengths and of smaller diameters to match heated lengths and hydraulic-equivalent diameters of fuel bundles are required. Current paper provides experimental data obtained in a short (0.6 m) vertical bare tube of a small diameter (6.28 mm) cooled with upward flow of SCW. Analysis of this dataset is also included. Main emphasis of this research is on liquid-like cooling within the possible conditions of future SCWRs and SCW SMRs. Two HT regimes are encountered at these conditions: 1) Normal HT (NHT) and 2) Deteriorated HT (DHT). Conditions at which the DHT regime appeared are discussed.

Abstract:
Abstract SuperCritical Water-cooled Reactors (SCWRs) represent potential improvements over traditional water-cooled reactors in many respects, including thermal efficiency. These reactors are still under development, however, thermalhydraulics data needed for their design are lacking. Experimentation is complex and costly. In spite of a large number of experiments in long bare tubes (pipes) cooled with SCW, developing SCWR concepts requires experimental data in bundle geometries cooled with SCW, which are usually shorter and will have smaller hydraulic-equivalent diameters. As a first step, tests have been conducted by others on heat transfer in short, vertical bare tubes cooled with the upward flow of SCW. The objective of this work is to analyze that collected data with particular attention to the Deteriorated Heat Transfer (DHT) regime. The DHT regime is characterized by reduced Heat Transfer Coefficients (HTCs) and consequently increased wall temperatures. As such, it represents a hazard to the safe operation of a Nuclear Power Plant (NPP). The results of this analysis indicate that DHT did occur in each of the tests analyzed, often seen as a gradual decrease in HTC along the heated length, but occasionally as a sharp “dip”. The DHT can occur along the heated length, when the bulk-fluid temperature is close to or within the pseudocritical region. The results also confirmed that the Dittus-Boelter correlation does not adequately predict HTCs within the pseudocritical region. Two other applied correlations (Gupta et al. and Mokry et al.) performed better, but neither was able to predict the occurrence of the DHT. The results of this analysis will be of use to designers and developers of SCWRs, and can help to plan future experiments.

Abstract:
Abstract Thermal efficiency and safety of Generation-IV nuclear-power-reactor concept - Supercritical Water-cooled Reactor (SCWR) depend on solid knowledge of specifics of SCW thermophysical properties and heat transfer within these conditions. As a preliminary, but conservative approach to uncover these specifics is analysis of experimental data obtained in bare tubes including numerical investigation. This paper presents the numerical investigation, based on computational fluid dynamics, of the heat-transfer characteristics of SCW flow in a 4-m long circular tube (ID = 10 mm). The flow and heat-transfer mechanism of SCW in the vertical tube under the influence of buoyancy and flow acceleration are analyzed. Results of numerical simulation predict the experimental data with reasonable accuracy. The results indicated that in the region of q/G &gt; 0.4 kJ/kg, the wall temperature distribution tends to be non-linear, and heat transfer may deteriorate. When Tb &lt; Tpc &lt; Tw, internal wall temperature shows peaks, which corresponds to heat-transfer deterioration. Meanwhile the position, where the deterioration occurs is continuously moved forward to the inlet as the heat flux increases. Velocity changes near the wall show an M shape according to mass conservation for the density change.

Abstract:
Abstract Despite the promising nature of alkali-surfactant-polymer (ASP) flooding, its application is limited by various technical issues and environmental concerns. The goal of mitigating the impact of these limitations has led to research into the oil recovery potential of alternative chemical agents. This study, therefore, focuses on investigating the potential of a "green" ASP formulation composed of monoethanolamine (ETA), sodium cocoyl alaninate (SCA) and Schizophyllan (SPG) for its enhanced oil recovery application. A conventional ASP formulation comprising sodium carbonate (Na2CO3), Sodium Dodecyl Sulfate (SDS) and partially hydrolyzed polyacrylamide (HPAM)was deployed for comparative purposes. The hardness tolerance of the green ASP shows that surfactant precipitation and scale formation could be mitigated. Lower surfactant concentration required to achieve low IFT and contact angle upon addition of alkali shows synergism in interfacial properties and wettability alteration. The ETA–SCA system yielded a better synergy in IFT reduction (minimum IFT of 4.73 × 10-2 mN/m) and wettability alteration (contact angle of 3° in 600 seconds) than the Na2CO3–SDS system (minimum IFT of 0.22 mN/m and contact angle of 5° in 600 seconds). Nevertheless, the conventional AS formulation exhibited better synergism with brine yielding minimum IFT of 1.52 × 10-2 mN/m. The ETA–SCA system also exhibited the ability to emulsify crude oil and form stable emulsions, a desirable property in chemical EOR processes. ETA had an insignificant impact on SPG's rheology, and the viscosity increased when SCA was added. The ETA–SCA–SPG solution showed shear thinning behavior at low shear rates. The oscillatory studies showed that both SPG and HPAM possess viscoelastic properties, with the green ASP retaining the viscoelasticity of SPG while HPAM loses its viscoelasticity in the presence of Na2CO3. SCA adsorption onto the sand surface was made unfavourable at a threshold of 0.3 wt% ETA. The green ASP formulation achieved an additional recovery of ~22%, while the conventional ASP formulation achieved ~19% additional recovery. Therefore, the green ASP formulation proves to have excellent oil recovery potential compounded by its environmentally benign nature.

The objective of this work is to determine the cyclic and stress corrosion cracking (SCC) crack growth rates (CGRs) in a simulated PWR water environment for Alloy 690 heat affected zone (HAZ). In order to meet the objective, an Alloy 152 J-weld was produced on a piece of Alloy 690 tubing, and the test specimens were aligned with the HAZ. The environmental enhancement of cyclic CGRs for Alloy 690 HAZ was comparable to that measured for the same alloy in the as-received condition. The two Alloy 690 HAZ samples tested exhibited maximum SCC CGR rates of 10−11 m/s in the simulated PWR environment at 320°C, however, on average, these rates are similar or only slightly higher than those for the as-received alloy.

Abstract:
Numerical investigation on storm surge characteristics would benefit the planners and designers of coastal structures and offshore platforms along the Krishna-Godavari (K-G) basin. The adjoining coastline has a wide range of geomorphological features and varying geometries due to the sediment deposition from the two major rivers, Krishna and Godavari. Two severe cyclonic storms (SCS) Laila (2010) and Helen (2013) that approached the basin from two different directions and made landfalls closer to each other were analyzed for determining the storm surge heights and currents along the K-G river basin. The maximum water elevations and maximum currents during the storm event and evolution of storm surge heights at different locations were studied. It could be concluded from the study that when a SCS event approaches K-G basin, in addition to the tide and wave effect, a maximum storm surge height and current of 1 m and 1.2 m/s can be expected along the coast, respectively. Similarly, the surge and current in the offshore regions were found to be 0.3 m and 0.8 m/s, respectively. These values may be considered while deriving design parameters for the offshore installations. The critical regions in the basin were identified where high surge heights and currents are expected.

Abstract:
In this paper, novel anode materials for solid oxide fuel cells which can directly operate liquid fuels at intermediate or low temperature were investigated. These materials were based on the activated carbons supported transition metal catalysts (AC-M) and the solid carbonate-ceria composite (SCC) materials, which were prepared via the sol-gel route. The SCCs possess both oxide-ion and proton conductivity, being used as multi-ion conductors. Activated carbons supported transition metals were used to improve the characters of anode materials and especially to enhance the anode catalyst function to liquid fuels, e.g., methanol. The internal reforming of liquid fuels was proved. There is no external reforming system needed. We used also the chemical methods to improve the commercial activated carbons. The microstructure, conductivity and electrochemical properties of anode materials were investigated as functions of the activated carbon pre-treating condition. Using these novel materials, the power intensity of 0.2 W/cm2 was achieved for fuel cells directly operating the methanol at 600 °C.

Abstract:
Fatigue due to vortex-induced vibrations (VIV) is one of the major uncertainties today in the design of slender offshore structures, such as risers, pipelines, umbilicals, tendons and mooring lines, required for oil and gas production in deep waters. The absence of reliable tools for quantitative analyses of this phenomenon is a technological barrier, which is being faced by several research groups. This paper presents valuable VIV results achieved by the author, using “wake oscillator” and “vortex tracking” models, when researching for his M. Sc. dissertation. Time domain analyses were performed using a commercial software. First results describe the response of the evaluated models for two degrees-of-freedom rigid cylinders by tracing lateral displacement versus flow velocity curves. These curves are plotted over others previously published in recognized recommended practices, articles and theses. Afterwards, VIV analyses results for a steel catenary 10-inch diameter riser in three-dimensional current profiles were compared to measured values. The considered riser, installed in 910m water depth offshore Brazil, is possibly the only monitored SCR with no VIV suppression devices in the world today. The results were considered satisfactory, despite some discrepancies: the model which appeared to be one of the most attractive for the rigid cylinder case, failed to predict VIV in the SCR under an irregular current profile, for example. Vortex tracking models presented excessive low frequency response in the SCR analyses. Authors believe that this response is unrealistic, and these frequencies can be dissipated by using a more adequate damping model than that employed by the utilized program.

Abstract:
The goal of this research was to provide a better understanding of the interface between root-knot nematodes, Meloidogyne spp., and their host in order to develop rational targets for plantibodies and other novel methods of nematode control directed against the nematode surface coat (SC). Specific objectives were: 1. To produce additional monoclonal SC antibodies for use in Objectives 2, 3, and 4 and as candidates for development of plantibodies. 2. To determine the production and distribution of SC proteins during the infection process. 3. To use biochemical and immunological methods to perturbate the root-knot nematode SC in order to identify SC components that will serve as targets for rationally designed plantibodies. 4. To develop SC-mutant nematodes as additional tools for defining the role of the SC during infection. The external cuticular layer of nematodes is the epicuticle. In many nematodes, it is covered by a fuzzy material termed "surface coat" (SC). Since the SC is the outermost layer, it may playa role in the interaction between the nematode and its surroundings during all life stages in soil and during pathogenesis. The SC is composed mainly of proteins, carbohydrates (which can be part of glycoproteins), and lipids. SC proteins and glycoproteins have been labeled and extracted from preparasitic second-stage juveniles and adult females of Meloidogyne and specific antibodies have been raised against surface antigens. Antibodies can be used to gain more information about surface function and to isolate genes encoding for surface antigens. Characterization of surface antigens and their roles in different life-stages may be an important step towards the development of alternative control. Nevertheless, the role of the plant- parasitic nematode's surface in plant-nematode interaction is still not understood. Carbohydrates or carbohydrate-recognition domains (CROs) on the nematode surface may interact with CROs or carbohydrate molecules, on root surfaces or exudates, or be active after the nematode has penetrated into the root. Surface antigens undoubtedly play an important role in interactions with microorganisms that adhere to the nematodes. Polyclonal (PC) and monoclonal (MC) antibodies raised against Meloidogyne javanica, M. incognita and other plant-parasitic nematodes, were used to characterize the surface coat and secreted-excreted products of M. javanica and M. incognita. Some of the MC and PC antibodies raised against M. incognita showed cross-reactivity with the surface coat of M. javanica. Further characterization, in planta, of the epitopes recognized by the antibodies, showed that they were present in the parasitic juvenile stages and that the surface coat is shed during root penetration by the nematode and its migration between root cells. At the molecular level, we have followed two lines of experimentation. The first has been to identify genes encoding surface coat (SC) molecules, and we have isolated and characterized a small family of mucin genes from M. incognita. Our second approach has been to study host genes that respond to the nematode, and in particular, to the SC. Our previous work has identified a large suite of genes expressed in Lycopersicon esculentum giant cells, including the partial cDNA clone DB#131, which encodes a serine/threonine protein kinase. Isolation and predicted translation of the mature cDNA revealed a frame shift mutation in the translated region of nematode sensitive plants. By using primers homologous to conserved region of DB#131 we have identified the orthologues from three (nematode-resistant) Lycopersicon peruvianum strains and found that these plants lacked the mutation.

Abstract:
Chemical composition and biological role of the surface coat (SC) of the root-knot nematodes, Meloidogyne spp. are described. SC proteins of M. incognita race 3 infective juveniles (J2) were characterized by electrophoresis and western blotting of extracts from radioiodine and biotin-labelled nematodes. J2 labelled with radioiodine and biotin released 125I and biotin-labelled molecules into water after 20 hours incubation, indicating that SC proteins may be loosely attached to the nematode. Antiserum to the principal protein reacted with the surface of live J2 and with surface proteins previously separated by electrophoresis. Human red blood cells (HRBC) adhered to J2 of several tylenchid nematodes over the entire nematode body. HRBC adhered also to nylon fibers coated with SC extracted from M. javanica J2; binding was Ca++/Mg++ dependent, and decreased when the nylon fibers were coated with bovine serum albumin, or pre-incubated with fucose and mannose. These experiments support a working hypothesis that RBC adhesion involves carbohydrate moieties of HRBC and carbohydrate-recognition domain(s) (CRD) distributed on the nematode surface. To our knowledge, this is the first report of a surface CRD i the phylum Nematoda. Gold-conjugated lectins and neoglycoproteins combined with silver enhancement have been used for the detection of carbohydrates and CRD, respectively, on the SC of M. javanica J2. Biotin reagents were used to trace surface proteins, specifically, on live J2. The labile and transitory nature of the SC was demonstrated by the dynamics of HRBC adherence to detergent-treated J2, J2 at different ages or fresh-hatched J2 held at various temperatures. SC recovery was demonstrated also by a SDS-PAGE profile. Monoclonal antibodies developed to a cuticular protein of M. incognita J2 gave a slight, but significant reduction in attachment of Pasteuria penetrans spores. Spore attachment as affected by several enzymes was inconsistent: alcian blue, which specifically blocks sulfyl groups, had no afffect on spore attachment. Treatment with cationized ferritin alone or catonized ferritin following monoclonal antibody caused significant decreases in spore attachment. Those results suggest a role in attachment by negatively charged groups.
