Effect of Surface Treatments on the Biaxial Flexural Strength of High Leucite Feldspathic Porcelains

The purpose of this study was to examine the effect of altering surface topography on the biaxial flexural strength (BFS) of four dental ceramics, Mir age (MI), Flexoceram (FL), Optec-HSP (OP) and IPS Empress (EM).Twelve groups of ten discs 123mm were prepared and fired according to the manufacturers' instructions. Ten specimens of each material were subjected to three surface treatments, polished, grit blasted and etched with 10% hydrofluoric acid (HF) for 2 minutes. Some specimens were gold coated for examination under Scanning Electron Microscope (SEM). BFS was determined using Lloyd M5K universal testing machine at a cross - head speed of 0.5 mm/min. A one-way ANOVA was used to evaluate the differences between groups.The results obtained showed that the only significant difference in the BFS was the 10% HF for OP and FL (One-way Anova, P<0.05). The decrease in BFS is most likely due to an increased surface flaw size, such that surface initiated crack growth dominates over the bulk internal flaw size of the ceramics.The BFS of dental porcelain used in this st udy may be governed either by the internal or surface flaws dependi ng on the manner of surface preparation. Specimens etched with 10% HF became weaker for OP and FL ceramics.

Ecuador and bilingualism a "mirage or reality?" a critical look at english as a foreing language

A critical review of government program on amplifying knowledge acquisition and professionalism in Ecuador to meet international standard and challenges. Based on this policy program, english language is required in every facet of education. Since inception, this cyclopean task has received accolade on the other hand a perverted criticism equally with an iffy of excuses probably a consequence on how the herculean curriculum is being managed mainly due to quality and caliber of apostles of this project. Before now however, this program was an absolute sham due to quack until government demonstrated unimaginable concern and decision to purge the program and rejuvenate teaching and learning of english proposed and execute capacitating programs as well as seasonal evaluation of teachers , teaching tools, strategies and approaches that gave a face-lift to the program and it`s administration.

Doorways to an Urban Mirage: Urbanity and the Situated Cinema Project

L’auteure applique les études phénoménologiques, les études des performances et les études cinématographiques à l’analyse de deux projets d’exposition présentés par Melanie Wilmink. Les projets Urbanity (Calgary, 2009) et Situated Cinema Project (Toronto, 2015) sont déployés à titre d’études de cas permettant d’examiner comment les architectures cinématiques oscillent, sur le plan performatif, entre posture critique et intégration pour structurer de nouvelles formes d’expérience esthétique du spectateur. Exposées en milieux extérieurs urbains à l’intention des publics itinérants, les deux installations créent des zones liminales — aux frontières du cinéma, de la galerie et de l’espace public — où les spectateurs peuvent se livrer à une expérience artistique ludique et tactile, créant momentanément des échanges et permettant à leurs corps d’expérimenter le contact avec des images projetées, des architectures construites et le rituel du visionnement. En s’appropriant des lieux habituellement réservés à la circulation, ou à d’autres aspects de la vie publique (comme les rues, les trottoirs et les places), les cinémas mobiles rompent le fil de la vie quotidienne, induisant détournements et interactions.

PIRO and sepsis stratification: reality or a mirage?

Um sistema de estadiamento tem como objetivo estratificar um determinado doente com uma determinada afeccao relativamente ao risco de eventos adversos; avaliar o potencial de resposta a um determinado tratamento; e monitorizar a resposta. Esses sistemas de estadiamento sao amplamente usados, sendo o mais conhecido o Classification of Malignant Tumours (TNM).(1) Em oncologia, o estadiamento de uma neoplasia constitui passo essencial no processo de tomada de decisao clinica, uma vez que e fundamental na avaliacao do prognostico e na escolha da abordagem terapeutica mais adequada.(1) Os conceitos de infeccao, sindrome da resposta inflamatoria sistemica (SRIS), sepse, sepse grave e choque septico, definidos na Conferencia de Consenso da American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM), foram a primeira tentativa de estratificacao da sepse.(2) Cedo, percebeu-se que a mortalidade dos doentes septicos e tanto maior quanto maior o numero de criterios de SRIS presentes, bem como a presenca de falencia orgânica (sepse grave) e, em particular, choque septico, ultrapassando os 50% nos estudos originais.(3)

L'oggetto sguardo nell'insegnamento di Lacan

The eye occupies a central place in the teaching of Jacques Lacan. In particular, it finds its almost final formulation in Seminar X (1962-63) and Seminar XI (1964). In these Seminars the field of vision is no longer the place of illusion and mirage of the subjective identity, but it becomes the same field crossed by Freud’s Unheimlich , namely that of the sudden apparition of what is invisible. ‘Look’ is the name that Lacan gives to this appearance. The effects of what Lacan calls the ‘look function’ are: a radical alteration of the coordinates of the visual field and an effect of anguish. In such a perspective, the visual field becomes the proper place to radicalize the idea of the ‘subversion of the subject’: the subject doesn’t look, he/she is looked, the gaze looks at the subject, grabs him/her, and, in doing so, it determines the subject. Thus, Lacan reduces the subject to a claim, a need, that crosses and distorts the visual field. This distortion forces the subject to meet his/her condition of object. From this point of view, visual arts are a privileged territory to establish a certain relationship with the constant distortion of the eye (since aesthetics is, after all, ethics), therefore with that objectual condition that each subject embodies.

The influence of fungicides as growth retardant on the growth and flowering of Ismelia carinata Schousb.

In consequence of the connection of European Union, traditional plant growth retardants will be withdrawn. Therefore, we tested the dwarfing effect of two fungicides, Bumper 25 EC and Mirage 45 EC comparing to Alar 85, a traditional growth retardant. Testplant was Ismelia carinata , a decorative ornamental annual plant. The 6 weeks old, once pinched back plugs were treated 3 times 3 weeks intervals with the given ch emicals with the concentration advanced by the producer. During the evaluation the height of plant s, the diameter of plant bush, number of branches, number and diameter of flowers were measured. In the aspect of plant size the most effective was Alar 85, we obtained compact, globular bushes with many lateral shoots. We did not find statistically proved difference between the tested chemicals, nor comparing to the control. In the aspect of flower bud number best results were obtained with Alar and Bumper, the results differed statistically from Mirage but statistically equal with the control. Th ere was not mentionable difference in the case of plant diameter and number of branches.

Hayek et Rawls sur la justice sociale : les différences sont-elles “plus verbales que substantielles” ?

Résumé Hayek, théoricien du "mirage de la justice sociale" et Rawls, auteur d’une "Théorie de la justice", semblent en opposition complète ; pourtant l’économiste a affirmé que les différences qui le séparaient du philosophe étaient "plus verbales que substantielles". Malgré des paradigmes opposés (évolutionnisme versus contractualisme), la gestation des normes est comparable chez les deux auteurs (anti-utilitarisme, impartialité, expérimentation) et aboutit à deux versions d’une même conception de la justice en société, par les normes retenues et leur hiérarchie (prééminence de la liberté, réelle augmentation des chances de chacun, amélioration du sort des plus démunis).

La production de modernités urbaines « glocales » : explorant les failles dans le miroir

Les villes sont — et ont toujours ete — des lieux fortement differencies, qui expriment une heterogeneite, des activites diverses, de la joie et du plaisir. Ceux sont des arenes pour la poursuite d’activites et de desire in-oppresse, mais aussi des espaces remplis de pouvoir systematique, de danger, d’oppression, de domination et d’exclusion. Pouvoir jongler entre ces tensions paradoxales, l’emancipation et la perte de pouvoir, a ete bien sur le quotidien des urbanistes, designer, ingenieurs sociaux, architectes et d’une vaste liste de visionnaires depuis les debuts des temps d’urbanisation. Cependant, les villes — et en particulier, les villes modernes — ne rendent pas l’apprivoisement facile. Dans les dernieres decennies, les parametres de la vie urbaine se sont orientes dans de nouvelles directions et se sont deplaces rapidement hors des contraintes dans lesquels les conceptions modernes et les pratiques gestionnaires urbaines avaient essaye de les retenir. Cette contribution soutient, premierement, que ce nouvel etat urbain presente une reaffirmation dramatique des forces modernes plutot que l’annonce d’une image, radicale, d’une nouvelle ville « post-moderne ». Dans une seconde partie, l’attention se tournera vers les nouvelles conditions et les failles qui infusent l’urbanisation contemporaine. La differentiation et la fragmentation a tous les niveaux sont devenues le resultat naturel de l’internationalisation, de la mondialisation et de l’imposition croissante d’une culture total(isante) de biens. En dernier lieu, cet article s’orientera vers des questions de justice sociale et urbaine dans cette nouvelle image de la ville. Alors que les plans urbains et d’urbanisation, durant la periode d’apres-guerre, se sont enveloppes dans une idee Rawlsienne d’une « Justice Equitable » autour de grands termes de redistribution, le mirage d’une ville et d’une region juste, a distribution equitable, a ete pulverise par la geopolitique d’accumulation de capitaux, prenant une nouvelle route importante apres les transformations cataclysmiques des deux dernieres decennies. Nous en concluons donc que les dynamiques contradictoires d’urbanisation hypermodernes actuelles ouvrent toute sorte de failles et de fissures. L’image d’une ville refletant la modernite est brisee, tel un kaleidoscope et tout sauf coherent. Ce sont justement dans ces « Third Spaces » (troisiemes espaces) interstitielles que resident les possibilites pour une intervention creative et pour toute autre experimentation innovatrice urbaine. Ce sont aussi dans ces endroits ou se negocie et se promulgue les questions et les pratiques d’une justice differente, du droit a la ville, et d’une vie urbaine emancipatrice. En effet, a l’interieur de ces interstices d’une logique commerciale d’urbanisation « glocale », se cache avec tout son potentiel energetique, la possibilite d’une forme et d’une vie urbaine, veritablement humaine.

Effect of pH on seedling growth of six cultivars of watermelon

Abstract Watermelon [Citrullus lanatus (Thunb.) Matsum and Nakai] cultivars Charleston Gray (CG), Crimson Sweet (CS), Dixielee (DL), Jubilee (JL), Mirage (MG), and Starbrite (SB) were grown in white quartz flintshot sand and watered daily with 0.01M sodium acetate buffer at pH 4.0, 4.5,5.0, 5.5, 5.0, or 6.5. After 14 days, stem length, leaf area, leaf, shoot and root dry weight, and number of lateral roots were measured. Number of roots increased with increasing pH from 4.0 to 5.0 in all cultivars except DL and CG. The number of roots of CG decreased with increasing pH. The number of roots of MG and SB had positive linear and quadratic correlations, respectively, with increasing pH. In all cultivars, root dry weight decreased with increasing pH from 4.0 to 5.5. At pH ≤4.5, all cultivars except CG had short or no tap roots and thickened lateral roots. CG had a decrease in stem length, leaf dry weight and area, and shoot dry weight with increasing pH, and was sensitive to high pH. However, MG and SB had an ...

EFFECT OF pH ON ROOT GROWTH OF SIX CULTIVARS OF WATERMELON

Watermelon [Citrullus lanatus (Thumb) Matsum and Nakai] cultivars Charleston Gray(CG), Crimson Sweet(CS), Dixielee(DL), Jubilee(JL), Mirage(MG) and Starbrite(SB) were grown in white quartz flintshot sand and watered daily with 0.01M sodium acetate buffer at pH 4.0, 4.5, 5.0, 5.5, 6.0, or 6.5. After two weeks, stem length, leaf area, leaf and root dry weight, and root number were measured. Nnumber of root decreased with decreasing pH below pH 5.0 in all cultivars except CG, which had an increase trend. Root number of MG and SB had negative linear and quadratic correlations respectively, with decreasing pH. In all cultivars, root dry weight increased with decreasing pH below pH 5.5. Under pH≤4.5, all cultivars except CG, had short or no tap root and thickened lateral roots. CG had a decrease in stem length, leaf dry weight and leaf area with increasing pH, and was sensitive to high pH. However, MG and SB had reduction in leaf area and stem length with decreasing pH, which suggests that MG and SB are sensitive to low pH. Although there were no differences in shoot parameters of 2wk-old plants of CS, DL and JL, observations made at 7 days after seeding indicated a possible pH effect on early growth of seedling.
