Popular Culture Portrayals of Latinos and Mental Health

Research on the portrayals of Latinos and mental health allows for the conceptualization of a long-lasting social issue. This project identifies the different film and television content that erroneously depicts Latinos with mental illnesses. This study takes a qualitative approach to help describe what roles Latino characters play in the media and how mental health is portrayed by such characters. We selected a purposive sample of cases where Latino roles were played by Latino actors, non-Latino actors, or actors with an “ambiguous” ethnic identity. This collaborative project poses the following research questions: We ask how are Latinos with mental health issues portrayed in popular culture

Effect of Temperature on Galvanic Corrosion of Non-Welded/Welded AISI 316L Stainless Steel in H3PO4

[EN] Galvanic corrosion of non-welded/welded AISI 316L SS at different temperatures (25 degrees C to 60 degrees C) at a Reynolds number of 1456 in phosphoric acid has been studied using polarization curves (by the mixed potential theory) and zero resistance ammeter (ZRA) measurements. Imposed potential measurements provide more active predicted coupled potentials and higher Galvanic current densities than those obtained using ZRA measurements. Polarization curves show that the anode of the pair is the non-welded AISI 316L. Galvanic current density values obtained from polarization curves increase with temperature. ZRA tests present the highest i(G) values at 60 degrees C; however, the values are very close to zero for all the temperatures studied. This is in agreement with the low value of the compatibility limit and of the parameter which evaluate the Galvanic phenomenon importance. Both techniques present the most positive potentials at the highest temperature.The authors would like to express their gratitude to the Spanish MAEC (PCI Mediterráneo C/018046/08).Sánchez Tovar, R.; Montañés, M.; Garcia-Anton, J.; Guenbour, A.

Soroprevalência da infecção pelo T. cruzi em doadores de sangue e cardiomiopatia chagásica em pacientes da região carbonífera de Coahuila, México

Context and Objective: Chagas disease is considered a worldwide emerging disease; it is endemic in Mexico and the state of Coahuila and is considered of little relevance. The objective of this study was to determine the seroprevalence of T. cruzi infection in blood donors and Chagas cardiomyopathy in patients from the coal mining region of Coahuila, Mexico. Design and Setting: Epidemiological, exploratory and prospective study in a general hospital during the period January to June 2011. Methods: We performed laboratory tests ELISA and indirect hemagglutination in three groups of individuals: 1) asymptomatic voluntary blood donors, 2) patients hospitalized in the cardiology department and 3) patients with dilated cardiomyopathy. Results: There were three levels of seroprevalence: 0.31% in asymptomatic individuals, 1.25% in cardiac patients and in patients with dilated cardiomyopathy in 21.14%. Conclusions: In spite of having detected autochthonous cases of Chagas disease, its importance to local public health remains to be established as well as the details of the dynamics of transmission so that the study is still in progress.Contexto e Objetivo: A doença de Chagas é mundialmente considerada uma doença emergente, é endêmica no México e no estado de Coahuila e considerada de pouca relevância.

Aspectos a considerar en el diseño y ejecución de espigones de baja cota : el caso del espigón de Fuentebravía

Los espigones de baja cota de coronación se han utilizado con éxito como obras necesarias para evitar la pérdida lateral de arena, en los casos en que se minimicen los efectos negativos que dichos espigones puedan causar en las playas cercanas. Han sido varios los espigones de baja cota de coronación utilizados en el litoral gaditano (Playas de Santa María del Mar en Cádiz, Regla en Chipiona, La Costilla en Rota, y Fuentebravía, en El Puerto de Santa María). Entre los factores a tener en cuenta en su diseño, destacan principalmente los siguientes aspectos (Gómez Pina, 2003): i) Técnicos, ii) Ambientales, iii) Económicos, iv) De integración en el entorno, v) Estéticos, vi) Recreacionales. Todos estos aspectos deben abordarse de una forma integral, siendo los tres últimos—aunque puedan parecer de menor importancia—cruciales a la hora de obtener la aceptación social, entre los distintos grupos que utilizan la playa

Lessons Learned Developing an Extension-Based Training Program for Farm Labor Supervisors

This article outlines a four-step model for developing a training program for farm labor supervisors. The model draws on key lessons learned during the development of the University of Florida Institute of Food and Agricultural Sciences Farm Labor Supervisor Training program. The program is designed to educate farm supervisors on farm labor laws and to support compliance with workplace regulations critical for the safety of farmworkers and the economic sustainability of agricultural industries. Attentive to building partnerships, assessing needs, tailoring the curriculum, and conducting evaluations, the model can be applied elsewhere to address the farm labor issues confronted by specialty crop growers in other states

Improvement of the electrochemical behaviour of Zn-electroplated steel using regenerated Cr(III) passivation baths

Conversion coatings based on trivalent chromium are more sensitive to the presence of zinc and iron impurities than the chromate formulations. This fact contributes to a decrease in the quality of passivation and to the generation of a significant amount of hazardous liquid waste. Recently, a new eco-innovative process based on Emulsion Pertraction Technology (EPT) is being implemented at industrial scale for selectively removing Zn and Fe from spent passivation baths in order to enhance the lifetime of the Cr (III) baths. In this study, the effect of Zn and Fe removal on the electrochemical behaviour of Zn-electroplated steel samples was evaluated by means of polarisation curves and electrochemical impedance spectroscopy measurements at open circuit potential conditions in 3.5 g/L NaCl solutions. The main objective was to assess the benefits brought by EPT using electrochemical methods. Cr (III) passivation baths regenerated using the EPT process have been compared to the bath used in a local industry as well as to fresh and spent baths. According to the results, the samples passivated in the EPT regenerated bath showed a significant improvement in their electrochemical behaviour compared to the samples passivated in the spent baths. This study concluded the suitability of EPT for regenerating Cr (III) passivation baths

Galvanic Corrosion of the Base AISI 316l/Micro-Plasma Arc Welded AISI 316l in Polluted Phosphoric Acid Media at Different Temperatures

[EN] In this work, the galvanic corrosion of the base AISI 316L stainless steel/micro-plasma arc welded AISI 316L stainless steel in phosphoric acid solutions polluted with sulphuric acid and chlorides was studied by means of the Zero-Resistance Ammeter technique. Experiments were performed at different temperatures (25, 40 and 60 degrees C) under flowing conditions (Reynolds number of 1456). Galvanic current density values are negative during the first hour of the test indicating that the welded alloy is corroding; then, they shift towards positive values indicating that the base stainless steel corrodes. Galvanic current density values reached stable values from the third hour of the tests performed at 25 and 40 degrees C, and during the last two hours of the test at 60 degrees C indicating passivation of the base alloy. Uniform corrosion processes occur for the AISI 316L alloy in polluted phosphoric acid solutions. Galvanic current densities increase with temperature according to Arrhenius plot. Impurities seem to increase galvanic corrosion and hinder passivation processes.This work was supported by the Spanish MAEC (PCI Mediterraneo C/8196/07, C/018046/08, D/023608/09, D/030177/10).

Effect of Welding on The Corrosion Behaviour of a Highly Alloyed Austenitic Stainless Steel UNS N06027 in Polluted Phosphoric Acid Media

[EN] The objective of this work is to study the effect of welding on the corrosion resistance of the austenitic stainless steel Alloy 59 (UNS N06027) as well as the galvanic corrosion generated by the base/weld pair estimated from the polarisation curves according to the mixed potential theory. The materials have been exposed to polluted phosphoric acid at several temperatures. The microstructure of the samples was studied by SEM and EDX analysis. The results show that the welding process shifts the corrosion potential values to more anodic potentials. The corrosion current densities and the passive current densities also increased by the effect of welding. This effect is aggravated with the increase in temperature. Open circuit potential values were located in the passive zone of the potentiodynamic curves, which means that the materials passivated spontaneously.The galvanic corrosion of the pair is not severe in the studied conditions. The ratio between the galvanic current density of the pair and the corrosion current density of the uncoupled anode is less than 5, which implies compatibility of the members in the couple.The authors acknowledge the Spanish Ministerio de Asuntos Exteriores y Cooperacion "MAEC" (PCI Mediterraneo C78196/07, D/023608/09, D/030177/10 and D/030177/10) for its financial support to the Krupp VDM Group (Germany) for the supplied alloys and to Dr. Asuncion Jaime for her translation assistance.Bakour, S.; Guenbour, A.; Bellaouchou, A.; Escrivá Cerdán, C.; Sánchez Tovar, R.; Leiva García, R.; Garcia-Anton, J.

A second transmissible cancer in Tasmanian devils.

Clonally transmissible cancers are somatic cell lineages that are spread between individuals via the transfer of living cancer cells. There are only three known naturally occurring transmissible cancers, and these affect dogs, soft-shell clams, and Tasmanian devils, respectively. The Tasmanian devil transmissible facial cancer was first observed in 1996, and is threatening its host species with extinction. Until now, this disease has been consistently associated with a single aneuploid cancer cell lineage that we refer to as DFT1. Here we describe a second transmissible cancer, DFT2, in five devils located in southern Tasmania in 2014 and 2015. DFT2 causes facial tumors that are grossly indistinguishable but histologically distinct from those caused by DFT1. DFT2 bears no detectable cytogenetic similarity to DFT1 and carries a Y chromosome, which contrasts with the female origin of DFT1. DFT2 shows different alleles to both its hosts and DFT1 at microsatellite, structural variant, and major histocompatibility complex (MHC) loci, confirming that it is a second cancer that can be transmitted between devils as an allogeneic, MHC-discordant graft. These findings indicate that Tasmanian devils have spawned at least two distinct transmissible cancer lineages and suggest that transmissible cancers may arise more frequently in nature than previously considered. The discovery of DFT2 presents important challenges for the conservation of Tasmanian devils and raises the possibility that this species is particularly prone to the emergence of transmissible cancers. More generally, our findings highlight the potential for cancer cells to depart from their hosts and become dangerous transmissible pathogens.We thank Bill Brown, Phil Iles, Billie Lazenby, Jacinta Marr, Jane McGee, Sarah Peck, Holly Wiersma and Phil Wise for assistance with sample collection and curation.
