Regulation of expression of copper responsive genes in Sulfolobus solfataricus:
No full textCopper is an essential micronutrient, but toxic in excess. Cells must maintain their internal level of copper within a narrow range of concentrations. This is accomplished mainly by copper efflux mediated by ATP-driven copper transporters that are induced at the level of transcription. Sulfolobus solfataricus has the ability to adapt to fluctuations of copper levels in its environment. Two Sulfolobus strains P2 and 98/2, showed different sensitivity to copper To better understand the molecular mechanism behind the organismal response to copper, the expression of the cluster of genes copRTA, which encodes the copper-responsive transcriptional regulator CopR, the copper-binding protein CopT, and CopA, has been investigated. The expression of the copR and copA transcripts was monitored by quantitative real-time RT-PCR. The data showed that only copA was induced by copper. By comparing the patterns of copA expression and cellular copper accumulation, as determined by Inductively Coupled Plasma Optical Emission spectrometry, it was concluded that the level of copA depends on the internal fluctuations of copper. To investigate the role of CopR, a mutant carrying a disruption of the copR gene was created. The mutant strain was uncapable of growth in the presence of excess copper, and under the same conditions no transcription of copA was observed. These data suggested that CopR positively regulates transcription of copA. The knockout mutant strain PBL2070, its parent strain and the mutant complemented with a wild type copy of copR, were compared with respect to their physiological and transcriptional response to copper. Results confirmed that, under copper stress, CopR, activates the transcription of copA, and its presence restores the wild type phenotype resistant to copper. Finally, a reporter system based on the thermostable β-glucuronidase of S. solfataricus was developed to study the promoter of regulated genes. This system was applied to the analysis of the copTA promoter region fused to the S. solfataricus β-glucuronidase reporter. GUS activity assays showed that after copper addition, the activity of GusB was consistent with the transcriptional changes observed for copA under similar conditions. The results provide the basis for a model of the molecular mechanisms of copper homeostasis in Sulfolobus.Ph.D.Includes bibliographical references (p. 87-113)by Aramis Alexis Villafañe Martine

Circuitos punitivos: limitaciones del populismo penal a partir de las prácticas de criminalización de mujeres trans y travestis en una zona roja argentina
No full textThis article analyses transgender women and transvestites’ criminalization practices in a red-light district, from two investigations located in La Plata city, Argentina. In order to achieve this proposal, we apply urban and action research tools to analyze security ensembles between different state agencies and neighborhood groups, so that the ways in which such practices are legitimized and become possible can be addressed. The daily regulation of inhabited spaces allows us to visualize disputes over the forms of appropriation, and to historicize social control of the supply of sex in the public space. Under this casuistry, we question limitations of the notion of punitive populism. We propose the figure of punitive circuits to visualize the territorial specificities linked to the insecurity that moral and criminal control practices have over the red-light district, and the multiplicity of people and agencies that intervene in its course. A partir de dos investigaciones situadas en la ciudad de La Plata, Argentina, nos focalizamos en el sector urbano denominado zona roja, para comprender la criminalización de mujeres trans y travestis. Para lograr este recorrido, mediante herramientas de indagación urbana e investigación-acción, reponemos ensambles en materia de seguridad entre diferentes agencias estatales y colectivos vecinales para abordar las formas en que dichas prácticas son legitimadas y devienen posibles. La regulación cotidiana sobre los espacios habitados nos permite visualizar disputas por las formas de apropiación, e historizar las formas de control de la oferta de sexo en el espacio público. Bajo dicha casuística, interrogamos limitaciones de la noción de populismo penal. Proponemos la figura de circuitos punitivos para visualizar las especificidades territoriales vinculadas a la inseguridad que tienen las prácticas de control moral y penal sobre la zona roja, y la multiplicidad de personas y agencias que intervienen en su curso.

Graviton–Thermodynamic Theory of Universal Emergence and Rebirth
No full textThis project explores a novel theoretical framework proposing that universe formation originates from a graviton-thermodynamic process triggered within supermassive black holes. It introduces the idea that gravitons, emerging from a primordial zero-state, catalyze thermodynamic transitions that lead to Big Bang–like events. The theory suggests an evolutionary model of universe reproduction governed by entropy, matter accumulation, and quantum conditions. All diagrams, equations, and concepts are original to the author, and the work is intended as a speculative but structured contribution to cosmology and quantum gravity discussions
Tendiendo redes sororas: experiencias feministas antiprohibicionistas en el movimiento cannábico de América Latina
No full textEn el presente texto, nos proponemos introducir algunas reflexiones sobre prácticas colectivas y líneas de pensamiento feminista antiprohibicionista en América Latina. Ante el paradigma prohibicionista reinante en la política de drogas en nuestra región, creemos que su injerencia diferencial en las vidas, los cuerpos y territorios latinoamericanos requiere de especial atención.
Se suele referir que la guerra “contra las drogas” en América Latina tiene cara de mujer. Antes que reducir el consumo y el tráfico de drogas, los ha aumentado al igual que la criminalización selectiva, de mujeres, lesbianas, travestis y trans. Estas alusiones nos permiten introducir experiencias concretas de los feminismos antiprohibicionistas actuales con especial atención a lo que acontece dentro (aunque también fuera) delmovimiento cannábico. Se trata de colectivos, redes y grupos de trabajo latinoamericanos con iniciativas propias que se encuentran en sus visiones generales sobre el patriarcado, la prohibición y el colonialismo. De este modo, pretendemos hilar historias mínimas de círculos de mujeres, latinas, que luchan por un cambio en las políticas prohibicionistas ya que vivencian sus daños muchas desde el sur del Río Bravo hasta Tierra del Fuego

Imprints in Dual Phase Hot Rolled Steel
No full textDP600 HR is one of Tata Steels hot rolled products. It is a dual phase steel unique to Tata Steel for its two step cooling process and low coiling temperature. The finished product has encountered several surface defects, one of which are imprints. In order to find the root cause for the imprints a literature study, a factory inspection and a number of experiments have been conducted. To find the origin of the imprint two coils have been produced with the intention to create imprints on the surface. With these trials and the observations in the factories within Tata Steel it is found that a loose oxide layer of 4-10µm thick is formed at the end of the hot strip mill process. Due to the low coiling temperature a fair amount of water remains on the strip until further processing. At both the recoiler and the pickling line a build-up of loose oxide is seen. From both former trials and the trials done during this project it is seen that a build-up of oxide leaves imprints with a depth of 20 to 150 µm. In order to confirm that the imprints can indeed be produced by loose oxides, two experiments were conducted. Loose oxide particles and bearing balls have been pressed into the steel surface with the result in both cases of imprints that can be compared to the ones obtained in the factory. In this work a new procedure has been developed to test the growth of the oxide layer as well as its adhesion to the steel surface. 1. To grow an oxide layer the Thermo Mechanical Testing Simulator is used. This device is normally used to test hot deformability of metals but its heating chamber can also simulating the run out table two step cooling cycle. Both cooling rates are varied between 30, 60 and 90 K=s keeping initial, intermediate and final temperatures equal to the factory values. 2. To test the adhesion of the oxide to the steel a tensile test is performed with the aid of the ARAMIS optical strain measuring system. Since the ARAMIS system follows optically the changes in the steel surface during straining the oxide layer is usually previously removed, because it will break first and interfere with the measurement. However this fact is used here to our advantage since the strain that is necessary to remove the layer can now be quantified. This loss in measurement data corresponds well to the initial loss of oxide from the sample. From the ARAMIS data it is seen that increasing the cooling rate of the first cooling step decreases the amount of strain required to break the oxide from the steel. The second cooling step does not have a pronounced effect on the adhesiveness. The microscopy analysis showed an unknown oxide layer at the steel/oxide interface. This layer is mainly iron oxide but contains an unusual amount of chromium. It is presently not known how the chromium is distributed in the oxide nor what its effects on the properties of the scale are. It is concluded that the imprints are caused by a build-up of loose oxide on the work rolls. The imprints can be prevented by not using the levelling and scale breaker work rolls. The adhesiveness of the oxide to the steel under deformation can be improved by reducing the cooling rate on the first cooling step. Using the Thermo Mechanical Test Simulator a controlled layer of oxide can be grown on steel samples. The adhesiveness of the oxide layer can then be tested by means of a tensile test while being recorded by ARAMIS. This set-up can be further improved to obtain a standardised oxide adherence testing method.Aerospace EngineeringAerospace Structures and Material
