    Geography as Due Process in Immigration Court

    Get PDF
    Using the procedural due process framework set forth by the Supreme Court in Mathews v. Eldridge, I argue that the current geographic distribution of immigration courts violates respondents’ rights to procedural due process by inhibiting their ability to appear, present evidence, and secure counsel. In so doing, I highlight the detrimental effects that geography has on remote communities, such as their ability to build pipelines towards access to counsel. Finally, I weigh and propose alternative solutions that balance the government’s interests in efficiency with the respondents’ interests in having a meaningful opportunity to avoid the harsh consequences of deportation

    Digestive aspartic proteases from s√°balo (Prochilodus lineatus): Characterization and application for collagen extraction

    Get PDF
    Acid proteases from s√°balo stomach mucosa were recovered using salting-out procedure. This single step produced an enzyme extract purified 1.8-fold over the crude extract with a recovery of 45.1% of its initial proteolytic activity. S√°balo proteases exhibited the highest activity at 45 ¬įC-pH 2.0, showed pH stability between 2.0 and 5.0 and retained more than 70% of its activity after incubation at pH 7.0 for 2 h. Fish extract was unstable at temperatures greater than 45 ¬įC. Its activity was inhibited by pepstatin A but not by PMSF, while EDTA and SDS showed partial inhibitory effects. Presence of CaCl 2 and MgCl 2 increased the proteolytic activity, while increasing concentrations of NaCl strongly decreased it. In addition, compared to the acid extraction method, the use of s√°balo enzymatic extract increased 1.7 times the yield of collagen extraction.Fil: Acevedo Gomez, Antonella Valeria.

    Effect of anodization on the surface characteristics and electrochemical behaviour of zirconium in artificial saliva

    Get PDF
    The paper is focused on elaboration of ZrO2 films on pure zirconium via anodizing inphosphoric acid with and without fluoride at constant potentials of 30 V and 60 V. Thestructure and composition of the films were investigated using scanning electronicmicroscopy, Raman spectroscopy and X-ray photoelectron spectroscopy. The composition ofthe oxides formed at both potentials can be identified as monoclinic ZrO2. In addition to Zrand O, the layers formed in phosphoric acid contain phosphorus originating from thephosphoric acid. When the phosphoric acid solution contains NaF, fluorine is alsoincorporated into the oxide layer. The oxides formed at a higher voltage have greaterroughness than those formed at 30 V. Anodized samples exhibit smaller current densitiesduring anodic polarization compared to the as-received zirconium covered with native oxide.Fil: Romonti, Daniela E..

    Meson phenomenology and phase transitions in nonlocal chiral quark models

    Get PDF
    We study the features of nonlocal chiral quark models that include wave function renormalization. Model parameters are determined from meson phenomenology, considering different nonlocal form factor shapes. In this context we analyze the characteristics of the deconfinement and chiral restoration transitions at finite temperature and chemical potential, introducing the couplings of fermions to the Polyakov loop for different Polyakov potentials. The results for various thermodynamical quantities are compared with data obtained from lattice QCD calculations.Fil: Carlomagno, Juan Pablo.

    Strong magnetic fields in nonlocal chiral quark models

    Get PDF
    We study the behavior of strongly interacting matter under a uniform intense external magnetic field in the context of nonlocal extensions of the Polyakov-Nambu-Jona-Lasinio model. A detailed description of the formalism is presented, considering the cases of zero and finite temperature. In particular, we analyze the effect of the magnetic field on the chiral restoration and deconfinement transitions, which are found to occur at approximately the same critical temperatures. Our results show that these models offer a natural framework to account for the phenomenon of inverse magnetic catalysis found in lattice QCD calculations.Fil: Gomez Dumm, Daniel Alberto.

    Preclinical efficacy of [V 4 Q 5 ]dDAVP, a second generation vasopressin analog, on metastatic spread and tumor-associated angiogenesis in colorectal cancer

    Get PDF
    Purpose Control of metastatic spread of colorectal cancer (CRC) remains as a major therapeutic challenge. [V 4 Q 5 ]dDAVP is a vasopressin peptide analog with previously reported anticancer activity against carcinoma tumors. By acting as a selective agonist of arginine vasopressin type 2 membrane receptor (AVPR2) present in endothelial and tumor cells, [V 4 Q 5 ]dDAVP is able to impair tumor aggressiveness and distant spread. Our aim was to evaluate the potential therapeutic benefits of [V 4 Q 5 ]dDAVP on highly aggressive CRC disease using experimental models with translational relevance. Materials and Methods Murine CT-26 and human Colo-205 AVPR2-expressing CRC cell lines were used to test the preclinical efficacy of [V 4 Q 5 ]dDAVP, both in vitro and in vivo. Results In syngeneic mice surgically implanted with CT-26 cells in the spleen, sustained intravenous treatment with [V 4 Q 5 ]dDAVP (0.3 jg/kg) dramatically impaired metastatic progression to liver without overt signs of toxicity, and also reduced experimental lung colonization. The compound inhibited in vivo angiogenesis driven by Colo-205 cells in athymic mice, as well as in vitro endothelial cell migration and capillary tube formation. [V 4 Q 5 ]dDAVP exerted AVPR2-dependent cytostatic activity in vitro (IC50 1.08 |jM) and addition to 5-fluorouracil resulted in synergistic antiproliferative effects both in CT-26 and Colo-205 cells. Conclusion The present preclinical study establishes for the first time the efficacy of [V 4 Q 5 ]dDAVP on CRC. These encouraging results suggest that the novel second generation vasopressin analog could be used for the management of aggressive CRC as an adjuvant agent during surgery or to complement standard chemotherapy, limiting tumor angiogenesis and metastasis and thus protecting the patient from CRC recurrence.Fil: Garona, Juan.

    Effect of surface modification on the corrosion resistance of Zr 2.5Nb as material for permanent implants

    Get PDF
    Zirconium is a potential material for permanent implants. In particular, surface modification induced by anodisation has proved to be effective to improve corrosion resistance while keeping good osseointegration. The combination of zirconium with niobium is supposed to develop a structure that presents a high corrosion resistance and continues having the mechanical resistance necessary for implants. The aim of the present work is to determine the viability of using anodised Zr-2.5Nb as implant material, and compare it with pure Zr. Electrochemical tests performed in the anodizing solution and in a simulated biological solution revealed that by anodising the materials a higher corrosion resistance is obtained. The improvement on the corrosion resistance is particularly noticeable in the case of the pure metal after a short period immersed in the simulated biological solution. But, after a long period of immersion, the alloy shows better performance.Fil: Farina, Silvia Beatriz. Universidad Nacional de San Mart√≠n; Argentina. Comisi√≥n Nacional de Energ√≠a At√≥mica.

    Deconfinement and chiral restoration in non-local PNJL models at zero and imaginary chemical potential

    Get PDF
    We study the deconfinement and chiral restoration transitions in the context of non-local PNJL models, considering the impact of the presence of dynamical quarks on the scale parameter appearing in the Polyakov potential. We show that the corresponding critical temperatures are naturally entangled for both zero and imaginary chemical potential, in good agreement with lattice QCD results. We also analyze the Roberge-Weiss transition, which is found to be first order at the associated endpoint.Fil: Pagura, Valeria Paula.
