Introduction: Understanding Neo-nomadic Mobilities beyond Self-actualisation

Fabiola Mancinelli ; Noel B. Salazar Academy of Mobility Humanities 2023 Mobility Humanities Vol.2 No.2

In 2018, Noel Salazar presented a paper at the 5th World Humanities Forum in Busan, South Korea, entitled “Moveo Ergo Sum: Mobility as Vital to Humanity and Its (Self)image,” in which he reflected on the existential need for people to move. Moveo ergo sum became the motto for the 2021 Global Mobility Humanities Conference (GMHC), encouraging us to think about the multiple ways in which mobility intersects with the construction of modern subjectivities (Salazar, “Introduction”). The expression recalled a quote from one of Fabiola Mancinelli’s research participants, a digital nomad from the US, whose words and unusual biography as a location-independent entrepreneur read like a declaration of selfactualisation through mobility, the desire to realise her full potential by constantly putting herself outside her comfort zone: “Travel is who I am, and this is not negotiable” (426). This remarkable coincidence was the trigger for us to propose the panel “Understanding Neonomadic Mobilities beyond Self-actualisation” to unpack the mobility-identity nexus as an analytical lens to explore the phenomenon of contemporary nomads.

According to the expectations around the world concerning future of energy sources, hydrogen will be in a few years the most important energy carrier for stationary and mobile applications. Hydrogen storage is the bottleneck on the race to commercialize technologies based on the use of hydrogen, and specifically for mobile applications, the research goal for 2010 is to develop a device with at least 6% w/w of storage capacity. Highly porous carbon-based materials are among the most promising materials, with Carbon Molecular Sieves CMS) and Carbon Nanotubes (CNT) the most studied. In both cases materials are structured in such a way that hydrogen must diffuse along channels (micropores) where walls represent a restriction for the adsorption/desorption cycle. In this study, an alternative material is prepared by separation of clay layers with silica nanoparticles of diameter around 12 nm. The hydrogen storage capacity increased from 0.12 for untreated clay to 0.40% w/w for nanoassembled clay, measured at 77 K and atmospheric pressure, and according to intercalated clay characterization, almost all the surface available on the clay was exposed for adsorption.

Hexavalent chromium is challenging to remove from industrial wastewater due the solubility and anionic nature of the chromates. Cr(VI) is typically removed by reduction to Cr(III), then precipitation or adsorption, which requires multiple steps and bulk reagents and generates sludge. In this project, we have evaluated a sintered alumina disk as a single step sorbent for Cr(VI). The disk was porous enough that 20 mL samples passed through in about 3 s using light suction. A single pass through the disk only reduced the [Cr(VI)] by 10–20%, but by passing the solution through the disk five times up to 80% was removed in samples up to 130 mg/L and up to around 50% for much higher concentrations. The five passes through the filter disk took less than a minute. On each pass through the disk the characteristic chromate UV–vis absorbance decreased, the Cr(VI) concentration (by the diphenylcarbazide method) decreased, and the pH rose slightly. The XRD pattern showed no change in the crystal structure of the alumina, but the SEM/EDS identified chromium on the surface. In addition to confirming chromium on the surface of the alumina, the XPS spectra showed a change in the binding energy of the aluminum, which is consistent with complexation. The system was fast and effective (in series), so should be applicable to industrial wastewater treatment.

Abstract. This paper presents the evolution the public policy on the health attention of hearing impaired people in Mexico has had. A socio-historical reconstruction has been made from those policies in which the backlog generated from its society integration within the field of the laws, plans and programs of social development is stated. Likewise, there is a mention of the findings detected from the execution of a social action project focused on that group; those findings set the basis for further proposals or lines of investigation. As a conclusion, there are given guidelines to link the public policy proposals with the challenges for the social action with that specific population. Palabras clave: Política pública, discapacidad auditiva, salud, intervención, bienestar social. Key words: Public policy, auditory disability, health, intervention, social welfare. Ⅰ. Introducción. Resumen. En este trabajo se presenta la evolución que ha tenido la política pública en materia de atención a la salud de las personas con discapacidad auditiva en México. Se hace una reconstrucción socio-histórica de dichas políticas, en las cuales se pone de manifiesto el rezago generado con respecto a su integración a la sociedad dentro del marco de las leyes, artículos, planes y programas de desarrollo social. Asimismo, se hace mención de los hallazgos detectados a partir de la implementación de un proyecto de intervención social enfocado a este grupo poblacional, lo cual sienta las bases para el planteamiento de propuestas y líneas de investigación a futuro. Finalmente, se presenta a manera de conclusión, algunas directrices que articulan las propuestas de política pública con los retos para la intervención social con grupos de población con discapacidad auditiva.

The maintenance of a healthy skin barrier is crucial to prevent and treat atopic dermatitis (AD) lesions and avoid infections. Glycomacropeptide (GMP) is a bioactive peptide that has demonstrated promising results as an anti-inflammatory and antipruritic therapy for experimental AD. This study aimed to analyze the effect of GMP on impaired cutaneous barrier-related signs in a rat model of AD lesions. AD-like dermatitis was induced on the skin by repeated topical applications of 2,4-dinitrochlorobenzene, and animals were orally administered GMP before or after AD induction. The expression of skin structural proteins and antimicrobial peptides (AMPs) was evaluated by immunoblot or immunohistochemistry, epidermal thickening was evaluated by histochemistry, the level of IFN-γ and changes in the microbiota were evaluated by quantitative polymerase chain reaction, and the quantity of fecal short-chain fatty acids (SCFAs) was evaluated by gas chromatography. GMP administration significantly increased filaggrin, β-defensin 2, and cathelicidin-related AMP expression in AD-like lesions. Involucrin expression was not modified. In GMP-treated animals, epidermal thickening and IFN-γ expression were strongly reduced in damaged skin. GMP treatment impacted the skin microbiota and prevented Staphylococcus aureus colonization, which is associated with AD. In addition, high levels of Bifidobacterium were detected in the feces of GMP-treated animals, and the acetic acid and butyric acid contents increased in animals prophylactically administered GMP. These results suggest that GMP markedly prevents or reverses skin barrier damage in rat AD-like lesions through a bifidogenic effect that induces fecal SCFA production with prolonged treatment. Our findings provide evidence that GMP may represent an optimum strategy for the therapy of the dysfunctional cutaneous barrier in AD.

This paper describes an experimental investigation performed to evaluate the low-velocity impact behavior ofprepreg-based carbon fiber reinforced polymers (CFRPs) and fiber metal laminates (FMLs) with and without open holessubjected to different impact energies. The laminates were made of carbon fiber/epoxy prepregs and aluminum layers andmanufactured by using autoclave. The impact responses of these laminates were experimentally obtained using a drop-weighttower at impact energies of 15, 20 and 30 J. After testing, the impact damage area of tested specimens was quantified from Cscanultrasonic technique. In addition, an X-ray tomography analysis was performed to assess the through-thicknessdistribution of damage in FMLs with and without open holes. The results showed that the woven FMLs exhibit the highestimpact peak force compared to that of CFRP plates due to the presence of aluminum layers, which induce a higherdeformation capability to the laminates. The presence of open holes in laminates tends to augment their damage extensionand decreases their impact peak force due to the local stress concentration effect. Nevertheless, it was observed by C-scanultrasonic images that the aluminum layers reduce the extent of delamination of laminates during the impact event. Postimpactevaluation using X-ray computed tomography showed that impact causes a severe damage to the laminates aroundtheir impact point and confirmed that matrix cracking and delamination are the principal damage mechanisms induced on thethrough-thickness direction of the FML plates. In specific, the results confirm that the aluminum layers provide good impactproperties and damage resistance when they are added to the CFRPs.

Tuberculosis in Mexico and the USA, Comparison of Trends Over Time 1990–2010

Background: The aim was to compare tuberculosis trends in Mexico and United States and to evaluate Mexican diagnostic methods and contact investigation. Methods: Retrospective comparative study of tuberculosis cases and incidence rates between both countries (1990–2010). Diagnostic methods and contact investigations were also evaluated for Mexico. Estimates were obtained from official websites. Results: In Mexico, no clear trend was found over time for cases. Pulmonary (PTB) and all forms of tuberculosis (AFTB) incidence decreased 2.0% annually. There was a negative correlation between the mean contacts examined per case and AFTB incidence (r2=–0.44, p=0.01) with a 33% reduction in AFTB incidence. In United States, PTB and AFTB cases have been decreasing 6.0% and 5.6% annually, respectively. The incidence decreased 7.3% and 6.8%, respectively. Conclusion: The incidence of tuberculosis in Mexico is decreasing slightly over time at 2% annually. In the United States, cases and incidence rates have been decreasing at a higher rate (5% to 7% annually). The inverse association between number of contacts examined per state and incidence rates in Mexico underscore the importance of reinforcing and improving contact investigations with the likely translation of a decrease of TB incidence at a higher rate.

Physiological and Molecular Characterization of Cephaleuros virescens Occurring in Mango Trees

Vasconcelos, Camila Vilela,Pereira, Fabiola Teodoro,Duarte, Elizabeth Amelia Alves,de Oliveira, Thiago Alves Santos,Peixoto, Nei,Carvalho, Daniel Diego Costa The Korean Society of Plant Pathology 2018 Plant Pathology Journal Vol.34 No.3

The objective of this work was to accomplish the isolation, molecular identification and characterizing the physiology of the causal agent of the algal spot in mango trees. For this purpose, the pathogen growth was assessed in different culture media, with subsequent observation and measurements of the filamentous cells. The molecular identification was made using mycelium obtained from leaf lesions and pure algae colonies grown in culture medium. Descriptions based on DNA sequencing indicated that the algae is Cephaleuros virescens. The algae must be isolated primarily in liquid medium for further pricking into agar medium. The highest mycelial growth average in Petri dishes occurred when the algae were grown in Trebouxia and BBM. Trebouxia enabled larger cells in the filamentous cells when compared to other culture media.
