Full textAbstract:
This article argues that much can be learned about the ways in which individuals grieve through a careful analysis of the presentation of loss in creative fiction, especially in terms of unconscious and uncensored responses presented indirectly through figurative language and structural patterns. It takes Bob Dylan's collection of songs about the anguish caused by lost love. Blood on the Tracks, as an example. An examination of the songs included in, and some rejected for, the album reveals developing responses to grief resulting from relationship breakdown, including the search for the absent one and for reconciliation; the intrusion of deep pain into everyday situations; the problem of infidelity and guilt; the attempt to reach a more detached perspective; the consequences of the pain becoming unbearable; and the attempt at a kind of closure. Taken together, the songs reveal how complex and contradictory responses to the agony of loss can be.

Full textAbstract:
Hyperglycemia-induced stress in the brain of patients with diabetes triggers the disruption of blood-brain barrier (BBB), leading to diverse neurological diseases including stroke and dementia. Recently, the role of microRNA becomes an interest in the research for deciphering the mechanism of brain endothelial cell damage under hyperglycemia. Therefore, we investigated whether mircoRNA Let7A (miR-Let7A) controls the damage of brain endothelial (bEnd.3) cells against high glucose condition. Cell viability, cell death marker expressions (p-53, Bax, and cleaved poly ADP-ribose polymerase), the loss of tight junction proteins (ZO-1 and claudin-5), proinflammatory response (interleukin-6, tumor necrosis factor-α), inducible nitric oxide synthase, and nitrite production were confirmed using MTT, reverse transcription-PCR, quantitative-PCR, Western blotting, immunofluorescence, and Griess reagent assay. miR-Let7A overexpression significantly prevented cell death and loss of tight junction proteins and attenuated proinflammatory response and nitrite production in the bEnd.3 cells under high glucose condition. Taken together, we suggest that miR-Let7A may attenuate brain endothelial cell damage by controlling cell death signaling, loss of tight junction proteins, and proinflammatory response against high glucose stress. In the future, the manipulation of miR-Let7A may be a novel solution in controlling BBB disruption which leads to the central nervous system diseases.

A la luz de las nuevas escrituras informáticas de la sociedad de la información y a partir de los dos conceptos diferentes de escritura que se encuentran en la Ley de Interpretación de 1978 del Reino Unido y en el art. 1.11 de los Principios Unidroit, así como de la contraposición del derecho italiano entre «scritture» (escritos) y «riproduzioni meccaniche» (reproducciones mecánicas), el trabajo investiga si la representación o reproducción de palabras en forma visible es necesaria para cumplir con los requisitos del derecho privado europeo en cuanto a la forma y la prueba por escrito, o si es suficiente cualquier forma de comunicación que preserve la documentación de la información contenida y sea reproducible en forma tangible. Argumentando la preferencia por la segunda solución, se establece una distinción entre, por un lado, «documentos declarativos» (es decir, los que constituyen el medio para efectuar declaraciones por escrito) y, por el otro, «documentos meramente representativos» (que en cambio no constituyen el medio para efectuar dichas declaraciones), teniendo en cuenta varias normativas vigentes a distinto nivel en el panorama del derecho europeo (y, en particular, ciertas normas del Codice civile, del BGB y del ABGB, del Código Civil español, del Código Civil griego y de la Law of Property inglés, por un lado, y el art. 1, 4.º apartado, lett. a y c, de la Convención Unidroit sobre el Factoring internacional y ciertos artículos y Considerandos de la Directiva 85/577/CEE, de la Directiva 97/7/CE y de la Directiva 2011/83/UE, por el otro).Recibido: 23 mayo 2019Aceptado: 3 julio 2019Publicación en línea: 30 octubre 2019

"Effect of tricyclic 1,2-thiazine derivatives in neuroinflammation induced by preincubation with lipopolysaccharide or coculturing with microglia-like cells."

Full textAbstract:
Abstract Background Alzheimer’s disease (AD) is considered the most common cause of dementia among the elderly. One of the modifiable causes of AD is neuroinflammation. The current study aimed to investigate the influence of new tricyclic 1,2-thiazine derivatives on in vitro model of neuroinflammation and their ability to cross the blood–brain barrier (BBB). Methods The potential anti-inflammatory effect of new tricyclic 1,2-thiazine derivatives (TP1, TP4, TP5, TP6, TP7, TP8, TP9, TP10) was assessed in SH-SY5Y cells differentiated to the neuron-like phenotype incubated with bacterial lipopolysaccharide (5 or 50 μg/ml) or THP-1 microglial cell culture supernatant using MTT, DCF-DA, Griess, and fast halo (FHA) assays. Additionally, for cultures preincubated with 50 µg/ml lipopolysaccharide (LPS), a cyclooxygenase (COX) activity assay was performed. Finally, the potential ability of tested compounds to cross the BBB was evaluated by computational studies. Molecular docking was performed with the TLR4/MD-2 complex to assess the possibility of binding the tested compounds in the LPS binding pocket. Prediction of ADMET parameters (absorption, distribution, metabolism, excretion and toxicity) was also conducted. Results The unfavorable effect of LPS and co-culture with THP-1 cells on neuronal cell viability was counteracted with TP1 and TP4 in all tested concentrations. Tested compounds reduced the oxidative and nitrosative stress induced by both LPS and microglia activation and also reduced DNA damage. Furthermore, new derivatives inhibited total COX activity. Additionally, new compounds would cross the BBB with high probability and reach concentrations in the brain not lower than in the serum. The binding affinity at the TLR4/MD-2 complex binding site of TP4 and TP8 compounds is similar to that of the drug donepezil used in Alzheimer's disease. The ADMET analysis showed that the tested compounds should not be toxic and should show high intestinal absorption. Conclusions New tricyclic 1,2-thiazine derivatives exert a neuroregenerative effect in the neuroinflammation model, presumably via their inhibitory influence on COX activity and reduction of oxidative and nitrosative stress.

Full textAbstract:
Although ZnSe/ZnS quantum dots (QDs) have emerged as apparently less hazardous substitute to cadmium-based QDs, their toxicity has not been fully understood. Huge levels of ROS production and associated difficulties comprise the underlying reason for nanomaterial toxicity in cells. This will cause both immunotoxicity and genotoxicity. In the current work, Zinc Selenium/Zinc Sulphide (ZnSe/ZnS) QDs was synthesized, characterized and analyzed for its role in oxidative stress induction in two cell lines (HepG2 and HEK) and Swiss Albino mice. ROS production and influence of catalase activity in ROS production measured by DCFHDA assay in both HepG2 and HEK cells after exposure to ZnSe/ZnS QDs. Assessment of nitrile radical formation carried out by griess reagent. Level of GSH is assessed as a marker for oxidative stress induced by QDs. Cell death induced after exposure to ZnSe/ZnS QDs investigated by Calcein AM-PI live dead assay. Apoptotic DNA ladder assay carried out for studying the potential of ZnSe/ZnS QDs to induce DNA fragmentation. In vivo bio-nano interaction was studied by exposing Swiss Albino mice to ZnSe/ZnS QDs via i.v. and i.p. injection. Antioxidant assays were carried out in brain and liver homogenates to study the oxidative stress. LPO, GSH, GPx, GR and SOD are considered as biomarkers for the stress analysis. Blood brain barrier (BBB) integrity also studied. Spleenocytes proliferation assay was carried out to study the immunotoxicity response. ZnSe/ZnS QDs do not induce visible oxidative stress upto a concentration of 50 μg/ml. Cell death occurs at higher concentration (100 μg/ml) caused by ROS production. Overall study apparently provide attentive information that ZnSe/ZnS QDs is not capable of eliciting any serious damages to liver and brain tissues which in turn substantiates its applicability in biomedical applications.

Full textAbstract:
Pour atteindre les objectifs de réduction de consommation et augmenter la flexibilité de la demande des bâtiments, il est nécessaire de disposer de modèles de prévision de charge de climatisation facilement diffusables sur site et performants qui permettent la mise en place de stratégies d’optimisation énergétique et d’effacement. Cette thèse compare plusieurs architectures de modèles inverses (« boite noire », « boite grise »). Un modèle semi-physique d’ordre 2 (R6C2) a été retenu pour prévoir la puissance de climatisation et la température intérieure moyenne en chauffage et en refroidissement. Il permet aussi d’interpréter des situations inédites (effacement), absentes de la phase d’apprentissage. Trois stratégies d’optimisation énergétique et d’effacement adaptées aux contraintes d’exploitation sont étudiées. La première permet d’optimiser la relance en chauffage afin de réduire la consommation et d’atteindre effectivement la température de confort le matin. La seconde stratégie optimise les températures de consigne sur une journée dans un contexte de prix variable de l’énergie, ceci afin de réduire la facture énergétique. Enfin, la troisième stratégie permet au bâtiment de s’effacer en limitant la charge tout en respectant des critères de confort spécifiés. Le modèle R6C2 et les stratégies ont été confrontés à un bâtiment réel (une école élémentaire). L’étude montre qu’il est possible de prévoir la puissance électrique et la température moyenne d’un bâtiment complexe avec un modèle mono-zone ; elle permet d’évaluer les stratégies développées et d’identifier les limites du modèleTo reach the objectives of reducing the energy consumption and increasing the flexibility of buildings energy demand, it is necessary to have load forecast models easy to adapt on site and efficient for the implementation of energy optimization and load shedding strategies. This thesis compares several inverse model architectures ("black box", "grey box"). A 2nd order semi-physical model (R6C2) has been selected to forecast load curves and the average indoor temperature for heating and cooling. It is also able to simulate unknown situations (load shedding), absent from the learning phase. Three energy optimization and load shedding strategies adapted to operational constraints are studied. The first one optimizes the night set-back to reduce consumption and to reach the comfort temperature in the morning. The second strategy optimizes the set-point temperatures during a day in the context of variable energy prices, thus reducing the energy bill. The third strategy allows load curtailment in buildings by limiting load while meeting specified comfort criteria. The R6C2 model and strategies have been faced with a real building (elementary school). The study shows that it is possible to forecast the electrical power and the average temperature of a complex building with a single-zone model; the developed strategies are assessed and the limitations of the model are identified

Full textAbstract:
Penelope emerges favourably from comparison with Clytemnestra and Helen, the main paradigms of infidelity in the present, and with the Nekyia’s catalogue of past heroines. The vulnerability of these ladies to seduction, corruption, and deception argues for taking Odysseus home, but the Phaeacians detain him abroad like Melampus in his catalogue. Penelope’s weaving was an antidote to the Dionysiac forces which threaten to put a suitor in Odysseus’ place, but when it is completed, she fears that she may kill her son in a maenadic frenzy, like Aedon who was turned into a nightingale. Her state of mind is demonstrated by her grief for the pet geese destroyed by an eagle in a dream told to her disguised husband. Her journey down to the storeroom and return with the covered basket containing the axes for the bow contest mimics the Arrephoria, and marks her transition from seclusion to marriage.

They also provide an overview of the rest of the book and how the book should be used to come to grips with quantum ideas that allow QCs to do things unimaginable for traditional computers. Alice and Bob emphasize that with perseverance everyone can understand the fundamentals of QC and how quantum physics enables entirely new ways of thinking about computational algorithms. They explain the book’s overarching narrative: quantum states, quantum entanglement, and quantum measurements provide the essential resources for QC and QIS.

The chapter is a flashback to Ancona, Italy, in the summer of 1946, at the end of World War II, close to the time Dimitri Shalikashvili, John Shalikashvili’s father, will be released from a British prisoner of war (POW) camp, ending his military career at the mere rank of major. The chapter overviews the impressive military and European aristocratic background of the Shalikashvili lineage; summarizes Dimitri’s service to the tsarist, Free Georgian, Polish, and German militaries; sets out Dimitri’s character and qualities, the positive aspects of which are shared by his son John; and explains how geostrategic shifts and other factors beyond Dimitri’s control ruined the chance this highly professional military officer had of measuring up to his ancestors, thereby providing comparative grist to mill the question of the determinants of success.

Abstract A Grief Observed reveals a “dark” side of C. S. Lewis for which his devoted readers may be unprepared. It is a candid, clinical, and sometimes shocking account of his grief following his wife’s death. The celebrated defender of the faith pulls no punches in accusing God of uncaring cruelty. He asks, what sort of God do we really have? He eventually comes to accept God’s providence in the death of his beloved “H,” but not before he explores the many avenues of loss. Grief has a history. Lewis was introduced to death when as a boy he stood before his mother’s corpse. Growing up, his fantasies and delight in male companionship insulated him from his later experience of passionate love for a woman. Indeed, Surprised by Joy only magnifies the improbability of sexual love, marriage, and the soul-baring grief expressed in his later work.

H.D. traveled to Vienna for her first sessions with Freud in March 1933, mentally anchoring Bryher in the therapy sanctum while she worked through their Corfu visions, which led Freud to think she was “stuck” in the “pre-Oed stage.” Freud also thought H.D. wanted to be Moses and establish a new religion. During her stay, H.D. crossed barbed wire and armed soldiers to reach the opera. Bryher came twice, and in June, their tram was stopped for a bomb search. In July, Sir John died, leaving an emotional vacuum for the illegitimate heiress. After the funeral, her brother announced his plan to marry, just when Bryher thought he might help her care for their mother. Bryher channeled her angry grief, harnessing money to help refugees gain necessary papers, and wrote Manchester based on a trip there to help Bergner’s stage fright, only to be rejected.

Full textAbstract:
Visitors to the Hull and East Riding Museum used to reach the climax of the Iron Age exhibition, Celtic World, by coming face-to-face with the extraordinary funerary offerings from three chariot burials at Wetwang Slack (Dent 1985). Now removed for urgent conservation, the iron swords from two male burials, their scabbards decorated with intricate, incised Celtic art, and the corroded iron mirror and sealed bronze container from the female burial, were displayed in Perspex cases. Beads of red glass ‘enamel’ adorned both swords and box, and a slender iron pin shone with a thin strip of glowing gold, entwined around a coral bead. These artefacts are marvellous testimonies to Iron Age craft skill, speaking of the repertoire of decorated objects through which power amongst these communities was underpinned and reproduced (Giles 2008). Behind these cases, setting the scene for these personal possessions or funerary gifts, is an oversized image—now the focus of that section of the museum: a reproduction of Peter Connolly’s impressive and moving reconstruction of a chariot burial (Fig. 19.1), loosely modelled on the Kirkburn K5 inhumation (see Stead 1991) and painted in the late 1980s. The image shows a tableau of mourners surrounding a grave, in which has been interred the body of an adult male (Fig. 19.1). He is lying over the wheels of a dismantled chariot, with a shield placed over his chest, and forequarters of pig lain on top. The box of the chariot (still attached to the pole shaft) is being lowered over the body like a coffin, before the grave is back-filled. The participants in this ceremony are predominantly male, with one woman at the edge in an apparent state of grief: two others are in the background, one keeping a pair of children at a distance from the proceedings. Two ponies are being led away from the scene, tossing their heads as if perturbed by the event. Such images have a powerful, instantaneous impact: ‘act[ing] at a distance, across the gallery, in a way a block of text cannot’ (James 1999a: 121).

Sylvester Judd died in 1860 at seventy years of age, just before he completed his history of Hadley, Massachusetts. Judd had lived through the transformation of his community from a small rural village where people fished massive runs of salmon and shad each spring, to an industrial center seated on the banks of a polluted river. One of his motivations for writing his history was to capture that fast-disappearing older world. It was a world where lawyers, shopkeepers, journalists, and farmers (and Judd had been three of those four) knew how to cut timber, kill and clean a turkey, catch fish, butcher a pig, tend a garden, work an orchard, and make cider. By the time of Judd’s death, wood was sold already cut into cordwood or milled to clapboards, meat was butchered at the abattoir, and cloth was woven in mills. It was a world that could not be brought back through his history, but one that Judd hoped through his history might at least be remembered. On July 24, 1882, when Theodore Lyman went before the people of his district to run for Congress, he reminded them that when he was a boy (then, Judd was in his fifties), the region’s industry had already begun to grow, although many of the state’s residents were still rural farmers. Yet by the time Lyman ran for Congress, a majority of the people of Massachusetts found their homes and their jobs in towns and cities. The world that Judd saw fading in the 1850s was indeed a thing of memory for some of those listening to Lyman in 1882. New England of the 1880s was a place, as Lyman noted, of “manufacturing towns with . . . sickly smells.” Yet without this progress, according to him, New England would have remained a place of “a few grist-mills here and there and houses whose occupants raised such crops as they could from the scanty soil.” If, by 1882, the people of New England had lost their more direct contact with the resources of nature, for many, the romanticized memory of that intimacy lingered on.

Due to the long lifespan of the cemetery, the pottery discovered in Żelazna Nowa is relatively diversified. Unfortunately, the majority of the graves have been partly damaged, and some have been completely destroyed. In many cases only grave bottoms were recorded, while the furnishings were scattered over a large area. Sometimes (e.g. in feature 56) one cannot be certain whether fragments of vessels uncovered in a grave pit indeed belonged to the burial urn. A few graves from the Younger Pre-Roman period were relatively well furnished in vessels, but the state of preservation rarely makes it possible to determine the actual number of vessels in particular graves. The same holds true with respect to Early Roman period pottery. Graves dated to this period often survived only in their bottom parts. Hand-made vessels prevail by far in the ceramic material. The only few wheel-made sherds were found in the cultural layer in the vicinity of the groove feature. Vessels used as burial urns were those representing Liana types II.2, II.3, and group III. The predominant vessel forms among Younger Pre-Roman period pottery were cups of Dąbrowska types I.2, 3, 4, 5, and 7, bowls II.13, and bulbous vessels. Roman period pottery is primarily represented by vessels of types II.2 and 3; group III; and small bowls of group VI.1 and 2. Some unique forms were identified as well, including a jug with a canal in feature 56 and a small bowl imitating glass vessels. A total of 490 small finds (including those from the modern period) were discovered in the cemetery. Due to severe damage to the cemetery, only some of them have been recovered from features (204), while 181 small finds have been found outside the context of features. Surface surveys were performed several times in the site, and these produced another 105 small finds, most of them found in the western and northern parts of the cemetery. With 54 items discovered, brooches prevail among the small finds. They include four Late La Tène brooches of type N, fragments of A.II or mixed A.II/IV brooches; A.III brooches; a significant number of A.IV brooches, including a few specimens of A.67 and A.68, trumpet brooches, and derivatives of strongly profiled brooches; brooches of series A.V, including A.96, A.120, and A.137; fragments of A.VI brooches; A.VII brooches; a fragment of a Gallic brooch of Rih’s variant 2.2.4; a brooch of Riha’s variant 5.17.5; and a Norico-Pannonian brooch of type A.236. Belt pieces included a clasp of type Kostrzewski 49, seven buckles (most of them of type D.1), two profiled group I variant 6 belt finials, and a set of belt fittings found inside the urn in grave 37, consisting of a buckle, a finial, and a ring. Ornaments are represented by fragments of a knotenring from feature 33, fragments of Kamieńczyk type bracelets and a bar bracelet, several appliques, among them a fragment of a silver plaque, and many fragments of melon beads and glass beads. Weapons are rare in the cemetery: surviving are primarily fragments of shield grips, rivets from shield bosses (fts. 6 and 7), complete spearheads (fts. 41, 48, stray find), and fragments of spearhead sockets (ft. 41, stray find). The finds included two sets of two spearheads each, found in graves, and uncontexted finds of a sword scabbard chape and a spur. Tools and objects of everyday use are relatively well-represented: 19 knives, 8 awls, 1 awl-like tool, 2 needles, 16 clay spindle-whorls, 2 whetstones, a polishing plate, iron fittings of the box, chest locks, fragments of key (?), a massive rim fitting, 2 fragments of combs, 2 fragments of dice, a fragment of an E.139–144 glass vessel, and an immense number of unidentified artefacts made of bronze and iron.

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.

Full textAbstract:
Box air turbulence is experimentally generated in a rectangular box by using four counter-rotating grids installed inside. Turbulence statistics are obtained from one-point measurement of LDA. Nearly isotropic turbulence with zero-mean velocity is realised in the midst of four rotating grids. The dissipation rate is estimated from the Taylor time microscale of velocity autocorrelation obtained from LDA measurement, since Taylor’s frozen turbulence hypothesis is not applicable. From this estimation, the Reynolds number based on the Taylor length microscale becomes about 200 at maximum in the present experimental apparatus. The mean falling velocity of small particle in turbulent flow is measured in the box turbulence. It is found that the mean falling velocity of the inertia particle could be smaller or larger than the terminal velocity, depending on the particle property, if the ratios of particle response time to turbulence time scale are the same.

Full textAbstract:
To numerically study biomass gasification in a three-dimensional bubbling fluidized bed, a CFD-DEM (computational fluid dynamics – discrete element method) model with heat transfer and homogeneous and heterogeneous chemical reactions is implemented. An ideal reactor model is used for the air-steam bubbling fluidized bed (BFB) gasification reactor assuming perfectly mixed solids and plug flow. A validated computational particle fluid dynamics (CPFD) model has been applied to investigate the sensitivity analysis of mesh grids as well as to find the optimum number of grids. The result shows that 7452 grid cells are the optimal number of cells for the existence BFB gasifier. The effects of key process operating parameters such as steam to biomass ratio (SB), as well as temperature shows that by enhancing the SB ratio or reactor temperature, gas yields increase. H2 and CO2 concentrations promote by increasing the steam to biomass ratio while CO and CH4 production drop. The optimal value of SB for the gasification process can be found in the range of 0.3 to 1.

The fuel rods in Pressurized Water Reactor (PWR) and Boiling Water Reactor (BWR) cores are supported by spacer grids. Even though spacer grids add to the pressure loss in the reactor core, spacer grids have several benefits in Light Water Reactors (LWRs). Some of these benefits are: (i) increasing the turbulence at the bottom of the reactor core for better heat transfer in single phase region of the LWRs, (ii) improving the departure nucleate boiling ratio results for PWRs, and (iii) improving critical power ratio (CPR) values by increasing the thickness of film in annular flow regime in the top section of the reactor core of BWRs. Several mathematical models have been developed for single and two phase pressure loss across the grid spacer. Almost all of them significantly depend on Reynolds Number. Spacer designs have evolved (incorporating mixing vanes, springs, dimples, etc), resulting in the complexity of the analysis across the grid, all the models have been compared not only theoretically but also quantitatively. For the quantitative comparisons, this work compares the results of mathematical spacer models with experimental data of BWR Full Size Fine Mesh Bundle Tests (BFBT). The experimental data of BFBT provides very detailed experimental results for pressure drop by using several different boundary condition and detailed pressure drop measurements. Since one CT-scanner was used at the bundle exit and three X-ray densitometers were used for the chordal average void distribution at different elevations to generate the BFBT results, detailed two phase parameters have been measured in BFBT database. Two bundle types of BFBT, the current 8×8 type and the high burn-up 8×8 type, were simulated. Three combinations of radial and axial power shapes were tested: 1) beginning of cycle (BOC) radial power pattern/cosine axial power shape (the C2A pattern); 2) end of cycle (EOC) radial power pattern/cosine axial power shape (C2B pattern); and 3) beginning of cycle radial power pattern/inlet peaked axial power shape (C3 pattern) in BFBT. The pressure drop in BFBT database was measured in both single-phase flow and two-phase flow conditions that cover the normal operational behavior. BFBT database gives the three combinations of high burnup assemblies with different radial and axial power shapes, namely C2A, C2B and C3, which were utilized in the critical power measurements. There are two types of spacers in this program — ferrule type and grid type. Therefore, detailed experimental data of BFBT was used for analyzing mathematical models of spacer grid for various boundary conditions of BWR in this paper. It was observed and discussed that pressure drop values due to spacer models can be significantly different.

An approach for simulating the assembly process where compliant airframe parts are being joined by riveting is presented. The foundation of this approach is the mathematical model based on the reduction of the corresponding contact problem to a Quadratic Programming (QP) problem. The use of efficient QP algorithms enables mass contact problem solving on refined grids, which is needed for variation analysis and simulation as well as for the consequent assembly process optimization. To perform variation simulation, the initial gap between the parts is assumed to be stochastic and a cloud of such gaps is generated based on statistical analysis of the available measurements. The developed approach is illustrated with two examples, simulation of A350-900 wing-to-fuselage joining and optimization of A320 wing box assembly. New contact quality measures are discussed.

Full textAbstract:
Chinese helium-cooled ceramics breeder test blanket module (CH HCCB TBM) is determined to be tested in ITER machine to get data for fusion reactor design and development in future. Chinese TBM is designed to occupy half of port C with 484mm in torroidal and 1660mm in poloidal. Radial length is 675mm. TBM is composed of box, 12 submodules and independent backplate. Box formed by first wall, grids and caps have 12 caivities to hold submodules. Box and submodules are supported by backplate by welding. Backplate distribute helium with flow rate 1.36kg/s to cool first wall and then part of it go out of TBM by bypass. The rest 0.77kg/s go on to cool caps and girds first and then cool submodules. Submodules with dimensions 250mm×202mm×318mm have independent cooling and purging systems connected to backplate manifold systems. In a submodule, two U-shaped structures hold breeding material Li4SiO4 pebbles. Out of the structure filled beryllium pebbles. Neutronics results show that tritium production is ∼64mg/FPD. Maximum temperature 538°C of structure material occurs in the front of first wall with surface heat flux 0.5MW/m2. Maximum total stress at first wall is 471MPa at 394°C; that in submodules is 426MPa at 400°C; that in backplate is 526MPa at 410°C, In order to explore development technologies for the TBM, a mockup with dimensions 484mm (torroidal)×592mm (poloidal)×675mm (radial) has been designed. The mockup with similar structure ignores bypass and purge gas systems. In the mockup, there’s only one submodule and the other three are replaced by submodule replacements. By discussions and investigations, development route has been decided and the mockup is being fabricated.

Full textAbstract:
Introdução: A espécie Anadenanthera colubrina var. cebil (Griseb.) Altschul é uma Fabaceae arbórea nativa do Brasil conhecida popularmente como angico-vermelho. É uma espécie de múltiplos usos (madeireira, medicinal, ornamental, para a recuperação de áreas degradadas, etc) com distribuição natural na Caatinga, Cerrado e Mata Atlântica. Como consequência da intensa degradação e da forte pressão antrópica que sofrem os locais de ocorrência naturais do táxon, as suas populações estão cada vez mais reduzidas e ameaçadas. Objetivo: Nosso estudo teve como objetivo realizar uma análise de modelagem de nicho climático para a A. colubrina var. cebil visando a seleção de sítios adequados para a conservação da espécie. Material e métodos: Para a realização desse estudo, foram coletados pontos de ocorrência georreferenciados do táxon na base de dados Gbif. Pontos repetidos e com erros foram removidos. Para a análise de modelagem utilizou-se o algoritmo bioclim e o software utilizado para a confecção dos mapas foi o Diva-Gis. Resultados: A espécie apresentou susceptibilidade de ocorrência extremamente alta em boa parte dos domínios da Caatinga, Cerrado e Pantanal. Na Mata Atlântica e Floresta Amazônica variou de baixa a extremamente alta. Nos Pampas foi predominantemente baixa. As regiões Nordeste, Centro-Oeste e Sudeste foram as que apresentaram maior susceptibilidade de ocorrência da espécie. Nas regiões Norte e Sul, boa parte de seus territórios apresentaram baixa susceptibilidade. Conclusão: Nossos resultados sugerem haver uma área bastante extensa para implantação de projetos que visem a conservação da espécie A. colubrina var. cebil, destacando-se sítios que ficam entre as latitudes de 5°S a 25°S.

Full textAbstract:
This paper has two objectives, (1) to examine the effects of spatial resolution, (2) to examine the effects of computational box size, upon turbulence statistics and the amount of drag reduction with and without the control scheme of wall oscillation. Direct numerical simulation (DNS) of the fully developed turbulent channel flow was performed at Reynolds number of 200 based on the wall-shear velocity and the channel half-width by using spectral methods. For the first objective, four different grids were applied to the same computational domain and the biggest impact was observed on the logarithmic law of mean velocity profiles and on the amount of drag reduction with 28.3% for the coarsest mesh and 35.4% for the finest mesh. Other turbulence features such as RMS velocity fluctuations, RMS vorticity fluctuations, and bursting events were either overpredicted or underpredicted through coarse grids. For the second objective, two different minimal channels and one natural full channel were studied and 3% drag reduction difference was observed between the smallest minimal channel of 39.1% and the natural full channel of 36.2%. In the near-wall region, however, the minimal channel flow did not exhibit significant difference in the mean velocity profiles and other lower-order statistics. Finally, from this systematical study, it showed that the accuracy of DNS depends more on the spanwise resolution, and it also confirmed that a minimal channel model is able to catch key structures of turbulence in the near-wall region but is much less expensive.

Full textAbstract:
The ship hull hydrodynamics impact to global energy consumption is about quarter of all energy used in the world. The amount of fuel consumed in an average Panamax container is over 200t per day. The ship hydrodynamics is improved by careful design of the body, but also all the appendages needed in the ship are aligned with streamlines to avoid excess resistance. The bow thruster tunnels and propeller units providing transversal thrust forces for maneuvering purposes are typically adding ship total resistance 2-3% per tunnel. The additional resistance from the tunnels is commonly decreased by vertical grid bars mounted in the opening – those reduce the resistance to 1-2% per tunnel. However those grids typically decrease the maneuverability increasing the propeller thrust resistance 7-12% depending on grid density and design. Vertical grids density having best performances reducing tunnel additional resistance contribute highest thrust losses. Elogrids (pat.pend) A new design for the tunnel opening grids has been developed to maintain the impact decreasing additional resistance at same level with commonly used dense vertical grids, but instead of reducing the thrust - keep or improve the thrust forces from the tunnel thrusters when needed in maneuvering. Basic idea of the stator type Elogrids is with the bars and circles prevent water flow into the tunnels while ship steaming and improve the propeller performances with same components to concentrate propeller jet produced at propeller pressure side and improve the flow pattern into the propeller at suction side. Testing The Elogrid performances has been simulated by computational fluid dynamics, designed based on the dimensions optimized and manufactured. Now these first pilots of the Elogrids has been installed to a passenger ferry with two Dp=2.4m tunnels and also tested in full scale. The testing of Elogrids include bollard pull tests to find these impact on thrust forces, vibrations and noise – and comparison of ship fuel economy before and after installation of Elogrids. The fuel economy comparison need as similar circumstances as possible to detect the impact reliably. Main challenge is slightly different conditions each time the ferry operates. A huge amount of ship data is needed to get statistically reliable results. Conclusions The full scale testing of Elogrids show 1.5% reduction of additional resistance, simulated results are between 2 – 2.5%. Compensating the draught differences lead test results closer to simulated values. Bollard pull testing show in average 5% improvement to thrust when Elogrids were installed, simulated values were between 1.6-3.6%. The simulated values were proposing bit higher saving potential, possibly explained with draught differences in test and simulation data, and for pull test they were noticed to be slightly conservative when compared to test results. The vibration levels dropped 12% in average after grids were installed.
