Abstract

The production of hydrogen from water using only a catalyst and solar energy is one of the most challenging and promising outlets for the generation of clean and renewable energy. Semiconductor photocatalysts for solar hydrogen production by water photolysis must employ stable, non-toxic, abundant and inexpensive visible-light absorbers capable of harvesting light photons with adequate potential to reduce water. Here, we show that a-Fe2O3 can meet these requirements by means of using hydrothermally prepared nanorings. These iron oxide nanoring photocatalysts proved capable of producing hydrogen efficiently without application of an external bias. In addition, Co(OH)2 nanoparticles were shown to be efficient co-catalysts on the nanoring surface by improving the efficiency of hydrogen generation. Both nanoparticle-coated and uncoated nanorings displayed superior photocatalytic activity for hydrogen evolution when compared with TiO2 nanoparticles, showing themselves to be promising materials for water-splitting using only solar light., Comment: 7 pages

16. Planificación corporativa en el territorio latinoamericano: Un análisis crítico de las privatizaciones de infraestructura en la Argentina en los años 90.

Author

Pino, Milider and Teixeira, Sérgio

Abstract

Privatizations are a central issue in Latin American geopolitics, as a strategy of control and power over underdeveloped countries. Its growing influence encompasses neoliberal processes since the 1980s, documents are analyzed with the purpose of extracting, examining, criticizing, discriminating government sources that contain data on concessions and privatizations of infrastructure and engineering systems that were built and developed with state investments, such as railways, hydroelectric plants, waterways, airports, roads, mineral extraction, among others, during industrialization. in America there was great economic, urban and industrial expansion and large capitalist consortia took advantage of this to privatize states that impacted the technical, social and territorial division of work, the spaces occupied by groups with power maintain dominance of the engineering systems that influence and they rationalize territory within global economic geography, shaping interactions between economies, influencing trade relations, investments and knowledge flows that significantly, directly and negatively affect the most vulnerable populations.

21. Chegamos ao destino final?: a uberização do trabalho do docente no Brasil

Author

Domingues, Letícia Barreto, Teixeira, Sérgio Torres, Miranda, Ana Elizabeth Sá, Domingues, Letícia Barreto, Teixeira, Sérgio Torres, and Miranda, Ana Elizabeth Sá

Abstract

This article presents the new form of labor appropriation adopted by online work platforms that has gained significant notoriety across the globe, especially in Brazil after the implementation of the Labor Reform. The trend towards uberization of work began with passenger transport and/or delivery services, and was later expanded to teaching, which is the class on which the study focused, analyzing the work performed in this archetype, the risks that the absence of formal hiring triggers for the class, the emptying of its historical achievements and the legal uncertainty that the absence of employment recognition triggers., O presente artigo apresenta a nova forma de apropriação do labor adotada pelas plataformas online de trabalho que ganhou expressiva notoriedade em todo globo, especialmente no Brasil após o implemento da Reforma Trabalhista. A tendência de uberização do trabalho foi iniciada com o transporte de passageiros e/ou serviços de entregas, sendo ampliada posteriormente para a docência, que é a classe na qual o estudo concentrou-se, analisando acerca do trabalho desempenhado nesse arquétipo, os riscos que a ausência da contratação formal desencadeia para a classe, o esvaziamento de suas conquistas históricas e a insegurança jurídica que a ausência do reconhecimento empregatício desencadeia.

22. “INOVAR É PRECISO!”: A DELIMITAÇÃO ADEQUADA DO PAPEL DO ESTADO NO PROCESSO DE INOVAÇÃO SOB AS PERSPECTIVAS NACIONAL E GLOBAL

Author

Teixeira, Sérgio Torres, Netto, Milton Pereira de França, Teixeira, Sérgio Torres, and Netto, Milton Pereira de França

Abstract

O presente artigo objetiva analisar o papel desempenhado pelo Estado no processo de inovação. Valendo-se da abordagem qualitativa, aliada à metodologia dedutiva e a levantamentos de informações de teor bibliográfico e documental, o trabalho estabelece a basilar distinção entre os institutos do crescimento e do desenvolvimento para, em seguida, examinar a correlação deste com o ato de inovar, a partir da leitura de proeminentes teóricos econômicos a respeito do elemento da produtividade. Mais à frente, trata de investigar as diferentes posturas que podem ser adotadas pelo ente estatal ao longo do processo de inovação e as suas aplicações em cenários de círculos virtuosos e viciosos. Ao prosseguir à identificação do disciplinamento normativo conferido à matéria no Brasil, o estudo busca diagnosticar a sua materialização prática por intermédio da compilação de métricas alusivas a investimentos na área da Pesquisa e Desenvolvimento (P&D) e tecer comparativos perante a conjuntura global de fomento à inovação. Por fim, após diferenciar os institutos da destruição criadora e da inovação destruidora, o artigo sustenta uma equilibrada atuação estatal no curso do processo de inovação.

23. Unique report of iliocaval endovascular reconstruction successfully enabling a kidney transplant

Abstract

Patients with end-stage renal disease and iliocaval venous obstruction are normally nonviable recipients of kidney transplantation. We report a case of a 34-year-old male patient who has been receiving hemodialysis as renal replacement therapy for 6 years due to immunoglobulin A nephropathy. Past medical history included multiple central venous catheter infections and catheter-associated thrombosis. Iliac confluence and inferior vena cava occlusion previously excluded the patient from the renal transplantation list. The exhaustion of venous access sites was already documented. After multidisciplinary discussion, the patient was proposed for endovascular iliocaval reconstruction aiming for a future kidney transplant. Iliocaval recanalization was achieved through bilateral femoral access. Inferior vena cava and iliac angioplasty were performed. A dedicated venous stent was deployed in the inferior vena cava, followed by a double-barrel reconstruction of the iliac confluence. Successful iliocaval recanalization was accomplished. Five months after kidney transplantation was performed with a deceased donor graft in the right iliac fossa. The postoperative period was uneventful. After 12 months, the patient remained free from kidney replacement therapies with a serum creatinine level of 1.3 mg/dL. To the best of our knowledge, this is the first clinical description of a successful kidney transplant in a patient with a previous iliocaval reconstruction.
