Abstract:
This paper studies the process adaptability of reclaimed clay sand with core sand, and discovers that the reclaimed clay sand with furan resin self-setting sand can be used to mix the water-glass sand and hot core box sand; but it can not be used to mix the cold core box sand and coated sand. The reclaimed clay sand with water-glass sand can not be used to mix the hot core box sand, cold core box sand and coated sand; the reclaimed clay sand with hot core box sand can be used to mix the water-glass sand, cold core box sand and coated sand; the reclaimed clay sand with cold core box sand can be used to mix the water-glass sand, coated sand and hot core box sand. The reclaimed clay sand with coated sand can be used to mix the water-glass sand, but when it is used to mix the hot core box sand and cold core box sand, it can meet general requirements of the casting production; the completely reclaimed clay sand can not be used to mix the resin self-setting sand.

Abstract:
ABSTRACT The box C/D small nucleolar RNPs (snoRNPs) are essential for the processing and modification of rRNA. The core box C/D proteins are restructured during human U3 box C/D snoRNP biogenesis; however, the molecular basis of this is unclear. Here we show that the U8 snoRNP is also restructured, suggesting that this may occur with all box C/D snoRNPs. We have characterized four novel human biogenesis factors (BCD1, NOP17, NUFIP, and TAF9) which, along with the ATPases TIP48 and TIP49, are likely to be involved in the formation of the pre-snoRNP. We have analyzed the in vitro protein-protein interactions between the assembly factors and core box C/D proteins. Surprisingly, this revealed few interactions between the individual core box C/D proteins. However, the novel biogenesis factors and TIP48 and TIP49 interacted with one or more of the core box C/D proteins, implying that they mediate the assembly of the pre-snoRNP. Consistent with this, we show that NUFIP bridges interactions between the core box C/D proteins in a partially reconstituted pre-snoRNP. Restructuring of the core complex probably reflects the conversion of the pre-snoRNP, where core protein-protein interactions are maintained by the bridging biogenesis factors, to the mature snoRNP.

Abstract The study investigates the key aspects involved in the flow of the air-sand stream from the machine chamber and in the core box filling in the core shooting and core blowing processes. The prevailing tendency to manufacture thin-walled castings with intricate channel structures has become the major determinant of castings quality and production rates. An important parameter of most core sand used in the shooting processes is the ability to eject from the machine chamber and the core-box filling capability. These properties are the key factors determining the feasibility of manufacturing intricate cores and the process efficiency. The research work outlined in this study focuses on establishing the performance criteria of core sand ejection from the machine chamber and of core box filling and sand compaction. The results given below were obtained for several new-generation core sand types, containing organic and inorganic binders, and designed to be used in hot-box, warm box and warm air processes.

Abstract Mechanization of the process of core making with the use of inorganic and organic binders is based, almost solely, on core blowing machines. Presently the core blowing machines are equipped with tools and devices that allow for application of different technologies of core making. Cold-box, hot-box and warm-air technologies require that core blowing machines shall be additionally equipped with either core-box pre-heating system or gas purging and neutralization system, or hot air purging systems. Considering the possibility of using varied, the most advantageous technologies of core making, the production of universal core blowing machines equipped with replaceable devices has been undertaken in Poland. The universal core blowing systems allow for mechanization of core making process also with the use of sand, bonded by modern, eco-friendly binder systems. The paper presents selected results-based evaluation of core blowing process showing the scope of conducted design and implementation works.

Abstract:
Abstract The effects of filling the core box cavity and sand compaction in processes of core production by blowing methods (blowing, shooting) depend on several main factors. The most important are: geometrical parameters of cavity and complexity of its shape, number, distribution and shape of blowing holes feeding sands as well as the venting of a technological cavity. Values of individual parameters are selected according to various criteria, but mostly they should be adjusted to properties of the applied core sand. Various methods developed by several researchers, including the authors own attempts, allow to assess core sands properties on the basis of special technological tests projecting the process into a laboratory scale. The developed criteria defining a degree or a filling ability factor provide a better possibility of assessing the core sand behavior during flowing and core box filling, which indicate the value and structure of the obtained compacting decisive - after hardening - for strength and permeability. The mentioned above aspects are analyzed - on the basis of authors’ own examinations - in the hereby paper.

Abstract:
Core shooting process is the most widely used technique to make sand cores and it plays an important role in the quality of sand cores as well as the manufacture of complicated castings in metal casting industry. In this paper, the flow behavior of sand particles in the core box was investigated synchronously with transparent core box, high-speed camera, and pressure measuring system. The flow pattern of sand particles in the shooting head of the core shooting machine was reproduced with various colored core sand layers. Taking both kinetic and frictional stress into account, a kinetic-frictional constitutive correlation was established to describe the internal momentum transfer in the solid phase. Two-fluid model (TFM) simulations with turbulence model were then performed and good agreement was achieved between the experimental and simulation results on the flow behavior of sand particles in both the shooting head and the core box. Based on the experimental and simulation results, the flow behavior of sand particles in the core box, the formation of “dead zone” in the shooting head, and the effect of drag force were analyzed in terms of sand volume fraction (αs), sand velocity (Vs), and pressure variation (P).

Abstract:
Abstract DEAD-box helicases catalyze RNA duplex unwinding in an ATP-dependent reaction. Members of the DEAD-box helicase family consist of a common helicase core formed by two RecA-like domains. According to the current mechanistic model for DEAD-box mediated RNA unwinding, binding of RNA and ATP triggers a conformational change of the helicase core, and leads to formation of a compact, closed state. In the closed conformation, the two parts of the active site for ATP hydrolysis and of the RNA binding site, residing on the two RecA domains, become aligned. Closing of the helicase core is coupled to a deformation of the RNA backbone and destabilization of the RNA duplex, allowing for dissociation of one of the strands. The second strand remains bound to the helicase core until ATP hydrolysis and product release lead to re-opening of the core. The concomitant disruption of the RNA binding site causes dissociation of the second strand. The activity of the helicase core can be modulated by interaction partners, and by flanking N- and C-terminal domains. A number of C-terminal flanking regions have been implicated in RNA binding: RNA recognition motifs (RRM) typically mediate sequence-specific RNA binding, whereas positively charged, unstructured regions provide binding sites for structured RNA, without sequence-specificity. Interaction partners modulate RNA binding to the core, or bind to RNA regions emanating from the core. The functional interplay of the helicase core and ancillary domains or interaction partners in RNA binding and unwinding is not entirely understood. This review summarizes our current knowledge on RNA binding to the DEAD-box helicase core and the roles of ancillary domains and interaction partners in RNA binding and unwinding by DEAD-box proteins.

Abstract:
The RNA polymerase II core promoter is a critical yet often overlooked component in the transcription process. The core promoter is defined as the stretch of DNA, which encompasses the RNA start site and is typically approx. 40–50 nt in length, that directs the initiation of gene transcription. In the past, it has been generally presumed that core promoters are general in function and that transcription initiation occurs via a common shared mechanism. Recent studies have revealed, however, that there is considerable diversity in core promoter structure and function. There are a number of DNA elements that contribute to core promoter activity, and the specific properties of a given core promoter are dictated by the presence or absence of these core promoter motifs. The known core promoter elements include the TATA box, Inr (initiator), BREu {BRE [TFIIB (transcription factor for RNA polymerase IIB) recognition element] upstream of the TATA box} and BREd (BRE downstream of the TATA box), MTE (motif ten element), DCE (downstream core element) and DPE (downstream core promoter element). In this paper, we will provide some perspectives on current and future issues that pertain to the RNA polymerase II core promoter.

Mestrado em Ciência e Engenharia de Materiais
O presente trabalho foi executado no âmbito do estágio curricular realizado na empresa de produção de componentes sanitários Grohe Portugal, sediada na zona industrial de Albergaria-a-Velha. Trata-se de uma indústria de fundição de latão, cujos produtos abrangem sobretudo torneiras e chuveiros. O trabalho teve como principal objetivo criar novas formulações de areias de macho para o processo Hot Box, por forma a melhorar a qualidade dos machos produzidos. Foi iniciada uma análise do sistema utilizado pela Grohe, incluindo o controlo das principais variáveis inerentes ao processo. Verificou-se que as matérias-primas utilizadas (areia, resina, endurecedor e conservante) eram as adequadas e, quantitativamente, o doseamento de cada uma delas era o correto. A distribuição granulométrica da areia utilizada (areia SP 45) cumpria as especificações técnicas dadas pelo fornecedor. Foi feita uma análise à temperatura das caixas de macho, tendo sido constatado que os valores eram os adequados ao processo. Foram realizadas análises térmicas à areia de macho: análise térmica diferencial (ATD) e análise termogravimétrica (ATG). Através da relação entre perdas de massa e reações endo/exotérmicas compreendeu-se melhor o processo químico de polimerização da resina furânica do tipo ureia-formaldeído usada no fabrico dos machos. Foram ainda realizados ensaios mecânicos de flexão e compressão a um conjunto de provetes representativos destes machos. Os provetes foram preparados numa máquina de machos manual e, numa segunda tentativa, utilizando partes de machos da produção. Em ambos os casos, os valores de resistência mecânica medidos após diferentes tempos de repouso após cura, ao longo de 6h, não foram constantes, revelando alguma falta de reprodutibilidade na preparação dos provetes. Numa segunda fase do trabalho, foram definidas diferentes formulações de machos, variando o tipo de areia utilizada e a proporção REC/A (quantidade de resina+endurecedor+conservante/quantidade de areia). Para isso foram utilizadas quatro areias diferentes (SP 45, SP 55, SP 49 e H-S 00108) e comparadas entre si em termos de distribuição granulométrica, tamanho médio de grão, morfologia do grão e área superficial específica. Para as diferentes quantidades de matérias-primas utilizadas, foram usadas as proporções de REC/A (em peso) = 1%, 1,4%, 1,6%, 1,9%, 2,4% e 2,8%. Em seguida, 0h e 24h após a preparação dos provetes, foram executados na empresa Fundipor (fornecedora da Grohe) ensaios de resistência à flexão, de dureza e de permeabilidade às diferentes composições de machos. Este conjunto de ensaios permitiu concluir que o melhor sistema para o processo Hot Box, é a nova formulação com areia SP 55 e proporção REC/A = 1,5%. Uma análise de consumos com esta formulação revelou uma poupança de 23% em resina, 22% em endurecedor e 25% em conservante.
This work was performed under the internship carried out in the sanitary components production company Grohe Portugal, located in the industrial park of Albergaria-a-Velha. Grohe is a brass foundry company, whose products include mainly faucets and showerheads. The work aimed to create new formulations of core sands for Hot Box process, in order to improve their quality and reduce fabrication costs. Firstly, an analysis of the system used by Grohe was carried out, including the control of the key variables inherent to the process. It was concluded that the raw materials used (sand, resin, hardener and additive) and the relative amounts were adequate. The size distribution of the sand used (SP 45) followed the technical specifications provided by the supplier. The temperature of the core boxes was measured and found correct. Thermal analyses were performed on the core sand: differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The relationship between mass loss and endo/exothermic reactions, allowed a better understanding of the chemical polymerization process of the furan resin urea-formaldehyde used in the cores. Bending and compression mechanical tests were also carried out to produce a set of representative samples of Grohe sand cores. Samples were firstly prepared manually in a core machine and, in a second attempt, using parts of production cores. In both cases, mechanical strength values measured at fixed intervals over a period of 6h after curing were not constant, showing that there was no reproducibility regarding the specimen’s preparation. In a second part of the work, different formulations of cores were defined by varying the type of sand used and the ratio REC/A (amount of resin + hardener + additive / amount of sand). For this, four different types of sand were used (SP 45, SP 55, SP 49 and H-S 00108) and compared in terms of particle size distribution, average grain size, grain morphology and specific surface area. For different quantities of raw materials used, the proportions in weight percent were REC/A = 1%, 1,4%, 1,6%, 1,9%, 2,4% and 2,8%. After 0h and 24h of sample preparation, bending tests, hardness tests and permeability tests were performed at Fundipor (a Grohe supplier). It was concluded that the best system for the Hot Box process should be a new formulation with sand SP 55 and a ratio of REC/ A= 1,5%. Moreover, the analysis of consumptions revealed that this formulation allows the following savings at Grohe: 23% of resin, 22% of hardener and 25% of additive.

Abstract:
Hepatitis C virus (HCV) is a single-stranded RNA virus belonging to the Flaviviridae and infects approximately 170 million people worldwide. Unlike other known RNA viruses, HCV causes a persistent infection in the majority of infected people and can lead to cirrhosis of the liver and hepatocellular carcinoma. For these reasons, HCV is rightly classified as a major human pathogen. HCV core protein is believed to form, by analogy with other members of the Flaviviridae family, the nucleocapsid of the virus. As well as this, core has been shown to modulate many cellular processes via interactions with numerous host-cell proteins. One such protein shown to interact with HCV core is the DEAD-box RNA helicase DDX3. In cells expressing either HCV core alone, or as part of the full length HCV polyprotein, DDX3 is redistributed from its normal diffuse cytoplasmic localisation to lipid droplets where it colocalises with core. The cellular function of DDX3 is still unknown although it has been suggested to be involved in processes such as splicing, translation and RNA transport. The aim of this study was to investigate the role of DDX3 in the life cycle of HCV. This was aided by the recent discovery of a fully infectious HCV genotype 2a clone (strain JFH-1), allowing previously inaccessible aspects of the virus life cycle to be studied such as particle assembly and release. A library of HCV core mutants (residues 1-59 only) was produced by error-prone PCR and subsequently expressed in bacteria and analysed for their ability to bind bacterially expressed DDX3 using a rapid, high throughput ELISA screen. Six HCV core residues, conserved throughout all genotypes, were identified as being critical for interaction with DDX3. These residues were confirmed as being critical for the interaction by transfection of mutant core (together with E1 and E2 to ensure correct processing of core) into Huh7 cells. None of the 6 mutant core proteins were able to redistribute cellular DDX3. In order to study the effects of abolishing the core-DDX3 interaction in terms of a fully infectious HCV life cycle, the 6 critical residues were individually mutated to alanine in the cell culture infectious strain JFH-1 genome. All 6 mutant JFH-1 RNAs were capable of replication and being translated. Further investigation however, suggested that replication rate of mutant JFH-1 RNA was >50-fold lower than that of wild type JFH-1 RNA replication. Mutant core proteins colocalised with the lipid droplet marker ADRP, indicating correct subcellular localisation of the viral protein. Western-immunoblot analysis of mutant cores also confirmed that core proteins of same molecular weight to that of wild type core were produced, suggesting mutant cores were correctly processed. Of the 6 mutant JFH-1 clones analysed, 5 of them were capable of secreting infectious HCV particles that could subsequently infect naïve Huh7 cells, as detected by immunofluorescence and RT-PCR. However, one mutant, in which residue 33 of core had been changed from glycine to alanine, was initially unable to produce infectious particles. Upon passaging of cells electroporated with this mutant, infectious particles were eventually produced. The production of infectious particles consistently coincided with the presence of a second mutation in the surrounding area of the originally mutated residue 33. However, JFH-1 RNA containing both the mutation at residue 33 and the second identified mutation nearby, was unable to produce infectious particles upon electroporation, suggesting another lesion elsewhere in the HCV genome may also be required in order to overcome the effect of mutating residue 33. A recent report has indicated that DDX3 may be a nucleo-cytoplasmic shuttling protein, utilising the CRM1 export pathway. To confirm this, DDX3 localisation was analysed in the presence of the CRM1 inhibitor leptomycin B (LMB). In the absence of LMB, DDX3 was seen to have a diffuse cytoplasmic localisation while a small proportion was also seen in the nucleus. In the presence of LMB however, a build-up of DDX3 was seen in the nucleus, confirming that DDX3 uses the CRM1 pathway to shuttle from the nucleus to the cytoplasm. The results of this study indicate that the interaction of the cellular DEAD-box helicase DDX3 with core protein is not essential for the life cycle of HCV. It has been shown here however, that the replication rates of mutant HCV RNA are lower than that of wild type, suggesting that DDX3 may enhance either replication itself, or translation (which in turn provides the machinery required for viral RNA replication). Investigating this possibility is the subject of our future work. The identification of glycine 33 of core protein as being essential for production of infectious virus particles (without abolishing replication) will provide the basis for further studies on the production of infectious particles and the role that core protein plays in this process. The panel of JFH-1 core mutants will also be useful in studying the core-DDX3 interaction in a much wider context involving the role of DDX3 in normal cells. This study has uncovered important details regarding the interaction between core and DDX3 and, together with the reagents produced throughout this investigation, should enable further successful study into the role of DDX3 in the life cycle of HCV.

Abstract:
Hepatitis C virus (HCV) is a major cause of chronic hepatitis worldwide. Present estimates predict that approximately 130 million people are infected with HCV with the majority of all infections progressing to chronicity, ultimately leading to fibrosis, cirrhosis and hepatocellular carcinoma. The virus, which belongs to the family Flaviviridae, has a single-stranded RNA genome of positive polarity that codes for a unique polyprotein of approximately 3000 amino acids. Core protein forms the viral nucleocapsid and is the most highly conserved of all the viral proteins. As well as playing a central role in virion assembly, core has been shown to modulate several cellular processes mainly due to its interaction with several host factors. One such cellular interacting partner of core protein is the DEAD-box RNA helicase DDX3. Although, the binding of these two proteins has been shown by yeast-two hybrid screening and co-immunoprecipitation (co-IP) assays, an authentic interaction is yet to be demonstrated in cells replicating the HCV JFH1 infectious clone. Nevertheless, IF analysis of JFH1-infected cells has shown a proportion of DDX3 is redistributed to distinct cytoplasmic sites where it colocalises with core, implying that these two proteins interact during virus replication. Six JFH1 core alanine mutants (F24A, G27A, I30A, G33A, V34A and Y35A) are known to disrupt this core-DDX3 colocalistion without altering viral genome replication following direct electroporation of viral RNA into cells. All mutants release infectious virus particles, except JFH1G33A. However, substantial reductions in RNA replication levels were observed at early time points following infection of naïve cells with the infectious mutant virus particles. Furthermore, the G33A mutation appears to allow the viral genome some degree of elasticity as during the serial passaging of G33Aelectroporated cells, a progressive increase in infectious virus particles was observed. Based on the diverse phenotypes of these mutants it is difficult to conclude as to which effects (if any) are directly related to the core-DDX3 interaction. In addition, DDX3 has become a topical host factor in HCV research following recent studies demonstrating that its knockdown from target cells causes an overwhelming reduction to HCV replication. However, these studies failed to demonstrate if the core-DDX3 interaction had any functional relevance to this effect. The aim of this study was to clearly define the role of the core-DDX3 interaction in HCV replication. Using highly specific antibodies, a co-IP assay was developed that was sensitive enough to detect an interaction between these two proteins from JFH1 RNAelectroporated cell lysates. Co-IP analysis of the 6 JFH1 core mutants revealed that only one of these (JFH1Y35A) appeared to completely abolish DDX3 binding. Detailed analysis of this mutant revealed its replication properties resembled those of the WT virus following both electroporation of the viral RNA into cells and infection of naïve cells with the virus particles, demonstrating that the core-DDX3 interaction is dispensable for virus replication in cell culture. In addition, DDX3 knockdown experiments revealed that as for JFH1WT, the replication of JFH1Y35A was equally sensitive to the depletion of endogenous DDX3 levels from target cells, indicating that the requirement of DDX3 for HCV replication is unrelated to its interaction with the viral core protein. Interestingly, sucrose gradient studies showed that DDX3 protein sedimented with the extracellular core protein from JFH1WT virus particles. Analysis of the JFH1Y35A virus particles found them to be less dense with a lower content of DDX3, alluding to the exciting possibility of DDX3 being a novel component of the virion. The results of this study indicate that the core-DDX3 interaction is not the mechanism through which HCV utilises this host factor for its replication. However, DDX3 may be incorporated into virus particles through its association with the nucleocapsid. Investigating the latter possibility is the subject of our future work. In a separate study, the replication properties of JFH1G33A and JFH1F24A were fully characterised. These two mutants were chosen for further analysis as they possessed unique properties relating to the virus proliferation in cell culture. Of the original 6 JFH1 core mutants, only JFH1G33A had a defect in secreting infectious virus particles. Upon passaging of cells electroporated with this mutant infectious particle production increased and eventually achieved peak titers similar to WT. The increase in infectivity consistently coincided with the appearance of a second mutation in close proximity to the originally mutated residue 33. Although, similar results were reported previously for this mutant by Dalrymple, (2007), the present study extended this work by confirming that these second site changes were compensatory mutations, which rescued the infectivity of JFH1G33A. In contrast to the assembly defect of JFH1G33A, JFH1F24A was efficient at secreting infectious virus following electroporation, however the infection kinetics of these particles was considerably lower than those derived from JFH1WT. Further analysis, suggested the delayed infection of JFH1F24A virus was likely due to an early event in the HCV lifecycle following entry into the cell and prior to the release of the infectious genome. Identifying the importance of glycine 33 in infectious virus assembly and phenylalanine 24 in virus spread provides the basis for further studies into the role that core plays in virus proliferation in cell culture. In its totality, this study has uncovered important details regarding the role of core, DDX3 and the core-DDX3 interaction in the HCV lifecycle.

Abstract:
Code clone Discovery Based on Functional Behavior by Ronald M Krawitz 2012 Legacy programs are used for many years and experience many cycles of use-maintenance-use-maintenance-use-etc. Source code or source code functionality is frequently replicated within these programs when it is written, as well as when it is maintained. Over time many different developers with greater or lesser understanding of the source code maintain the source code. Maintenance developers, when they have limited time or lack understanding of the program, frequently resort to short cuts that include cutting and pasting existing code and re-implementing functionality instead of refactoring. This means a specific functionality is often repeated several times, sometimes using different source code. Blocks of replicated source code or source code functionality are called code clones. Removing code clones improves extensibility, maintainability, and reusability of a program in addition to making the program more easily understood. It is generally accepted that four types of code clones exist. Type-1 and Type-2 code clones are comparatively straightforward to locate and tools exist to locate them. However, Type-3 and Type-4 code clones are very difficult to locate with only a few specialized tools capable of locating them with a lower level of precision. This dissertation presents a new methodology that discovered code clones by studying the functional behavior of blocks of code. Code Clone Discovery based on Functional Behavior (FCD) located code clone by comparing how the blocks of code reacted to various inputs. FCD stimulated the code blocks with the same input patterns and compared the resulting outputs. When a significant portion of the outputs matched, those blocks were declared to be a code clone candidate. Manual analysis confirmed that those blocks of code were code clones. Since FCD discovered code clones based on their black-box behavior, the actual source code syntax was irrelevant and manual inspection further confirmed FCD located code clones that included Type-3 and Type-4 code clones which are frequently excluded from code clone detection tools. FCD recognized the code clones regardless of whether or not they use identical code, similar code, or totally dissimilar code. This new technique allows for an improvement in software quality and has the potential to significantly reduce the cost of software over its lifetime.

Abstract:
AbstractSoftware verification has recently made enormous progress due to the development of novel verification methods and the speed-up of supporting technologies like SMT solving. To keep software verification tools up to date with these advances, tool developers keep on integrating newly designed methods into their tools, almost exclusively by re-implementing the method within their own framework. While this allows for a conceptual re-use of methods, it nevertheless requires novel implementations for every new technique.In this paper, we employ cooperative verification in order to avoid re-implementation and enable usage of novel tools as black-box components in verification. Specifically, cooperation is employed for the core ingredient of software verification which is invariant generation. Finding an adequate loop invariant is key to the success of a verification run. Our framework named CoVEGI allows a master verification tool to delegate the task of invariant generation to one or several specialized helper invariant generators. Their results are then utilized within the verification run of the master verifier, allowing in particular for crosschecking the validity of the invariant. We experimentally evaluate our framework on an instance with two masters and three different invariant generators using a number of benchmarks from SV-COMP 2020. The experiments show that the use of CoVEGI can increase the number of correctly verified tasks without increasing the used resources.

Abstract:
AbstractThe many faces of the European Council make it a core component of the institutional machinery maintaining relations between the EU and third countries, including Turkey. This chapter identifies the European Council’s roles as the EU’s ‘master of enlargement’, ‘external voice and crisis manager’, and ‘agenda and direction setter’ as its three primary functions that drive the EU–Turkey relationship. The central focus of the chapter is the evolution of the European Council in framing relations with a candidate country—or what many now call a ‘strategic partner’—and the identification of the critical turning points and shifts in the central functions, internal dynamics, and preferences of this key institution. The findings indicate a growing trend toward a more conflictual, relatively hostile relationship between the European Council and Turkey as a result of diverging geopolitical interests—especially in the Eastern Mediterranean—and normative considerations. Furthermore, the analysis reveals an expanding impact of bilateral issues and member states’ individual preferences on the European Council’s role as a driver of EU–Turkey relations. Still, with their powers, the Heads of State or Government are likely to remain a key driver of the future trajectory of the relationship, demonstrating an increased interest in ‘thinking outside of the accession box’ and in framing a relationship model that would safeguard EU–Turkey relations amidst growing disagreements with Ankara.

Abstract:
This paper presents the results of experimental and numerical studies of hot distortion phenomenon in the phenolic urethane cold box systems. Dual Pushrod Dilatometer has been used to measure a thermal expansion/contraction of phenolic urethane cold box sand core specimens at temperature range from 25° C to 800° C. The high temperature tensile tests showed that the tensile strength of the phenolic urethane cold box silica sand cores is significantly affected by the bench life, temperature and binders level. High temperature hot distortion furnace tests on cylindrical cores showed that some aluminum coatings increase the temperature limit when distortion starts, but can’t prevent it. The hot distortion test aluminum castings showed that regardless of the application of coating, the type of coating, and anti-veining additives, all cores (silica sand) with density less than the density of the molten metal (aluminum alloy) were significantly distorted. Numerical simulations of the liquid metal flow around the cylindrical sand core and analysis of dynamic forces acting on the core during fill process showed that a buoyancy force is the major contributor to the hot distortion. It is concluded that the one of the solutions in preventing the hot distortion of sand cores is increasing their weigh, which will balance the buoyancy force and will bring the resultant force to the minimum. The hot distortion test castings using zircon sand cores (both coated and non-coated) with density almost equal to the density of the molten aluminum proved our predictions, and hot distortion has been prevented.

Abstract The truss core surpasses the honeycomb core depending on the tasks. The height of core is limited by press forming and so on. Therefore, we developed a method by folding mountain / valley lines like origami. The origami forming method has the feature that it can be done from paper to metal by the same method. By examining three-point bending tests, drop tests, and analyzing them, we show that the structure that space-filled with cores obtained by the origami forming method called ATCP will be a box for both excellent cushioning material and transporting. Moreover, we also show that the core structure obtained by this has excellent sound insulation performance.

Full text
Abstract:
A 3D steam flow within simulated fuel bundle of Large Scale Test Facility (LSTF), a PWR system simulator, has been investigated by Computational Fluid Dynamics (CFD) analysis with Ansys Fluent code to clarify influences of the steam flow on Core Exit Temperature (CET) response. A LSTF SBLOCA experiment with 1.5% hot leg break as the OECD/NEA ROSA-2 Project Test 3 was simulated by the CFD code to clarify relation between CET and fuel rod surface temperature. A portion of the LSTF core above the mixture level up to around CET sensors was modeled by taking into account high, medium and low heat-zone heater rod bundle, including internal structures such as end-box and upper core plate (UCP). Simulation of steady-state condition at a certain time when mixture level lowered to a certain position at around half of the core height (post-5) was carried out by considering relevant boundary conditions which were developed based on the LSTF Test 3 results. The calculation results revealed that inner structures of the core such as core spacer, end box and UCP indeed affect the CET due to heat transfer from hot steam to these cool structures. 3D flow mixing may also contribute to the final CET values and the delayed increase in the CET relative to the Peak Cladding Temperature (PCT) in the core.

Abstract:
On automotive vehicles, the cowl box is a volume located at the bottom of the windshield, under the cowl top grille. It provides external fresh air to the HVAC (Heating, Ventilating and Air Conditioning) unit and it is used to collect water coming from the windshield under rain conditions. This box is designed as a tranquillisation chamber to segregate water from air and avoid the ingress of rainwater into the HVAC unit. However, as the area is awkward to access with measuring devices, our knowledge about the physics of flow in the cowl box is limited. The present work aims to advance our knowledge through experimental work on the air/water flow in a simplified cowl box in order to optimize the box size and improve numerical models. This paper will focus on the analysis of the bathtub vortex, which is potentially responsible for insufficient draining of the water collected in the cowl box. The experimental set-up consists of a Plexiglas parallelepiped representing a simplified cowl box with top cowl grille, HVAC inlet and drain. A blower generates airflow through the HVAC inlet. A water sheet, with controlled flow rate, is created on an inclined plane representing the windshield. Velocity measurements of all components are obtained by PIV (Particle Image Velocimetry) in the liquid phase and the surface level is recorded by a capacitance probe near the drain. Moreover, contour detection of the vortex core is achieved using a high-speed camera. Results show a relationship between the pressure loss generated by the airflow in the cowl box, the water level and the vortex structure. The modification of the vortex structure as well as the modification of velocity components near the air core are visible only in transient stages. These experimental results give us today some insight to understand the physical phenomena occurring in the cowl box.
