Este artigo aborda os impactos da crise financeira na intervenção do Estado junto ao mercado, tendo como elemento de análise a crise financeira em 2008/2009, suas repercussões no Brasil e na Argentina sobre o emprego dos trabalhadores. No primeiro caso, focaliza como  objetos de investigação a indústria de mineração e o setor automobilístico. No segundo caso, enfoca o capitalismo informacional no modo como atinge as formas de contratação dos trabalhadores e o processo de trabalho.Palavras-chave: Trabalhadores, crise financeira, capitalismo informacional, desemprego.THE CAPITALIST CRISIS IN THE 21 ST CENTURY AND THE BACKLASHES FOR THE WORKERSAbstract: The impacts of the financial crisis over the State's intervention in the market are approached, regarding as elements of analysis the financial crisis of 2008/2009, and its backlashes upon the worker's jobs in Brazil and Argentina. In the first case the objects of investigation are the mining industry as well as the automobile sector.

NOVAS FORMAS DE EXPLORAÇÃO DO TRABALHO E INFLEXÕES DO MODELO DE DESENVOLVIMENTO: precarização do trabalho e migração no século XXI

Análise da precarização das relações de trabalho em duas perspectivas: associada à migração de trabalhadores e com base na noção de informação como trabalho. Migração e precarização são a tônica do trabalho dos migrantes, com desrespeito aos direitos trabalhistas. O trabalho informacional comunicacional, por sua vez, permite verificar a sua vinculação com os processos de valorização e acumulação do capital. 

Advanced osteosarcoma of the maxilla : a case report

Osteosarcomas are primary malignant bone tumours in which mesenchymal cells produce osteoid. It is generally the most common malignant bone neoplasm, although lesions of the jaw are uncommon. Osteosarcoma of the jaw (JOS) presents a lower incidence of metastasis and a better prognosis than osteosarcoma of the long bones. However, patients with JOS can exhibit advanced tumours, mainly when early diagnosis is not performed. This article reports on a case of an advanced osteosarcoma of the maxilla. A 38-year-old woman was referred for evaluation and treatment of recurrent fibrous dysplasia of the facial bones. The patient related that she had been diagnosed with fibrous dysplasia four years earlier and, since the first diagnosis, she was submitted to four surgical interventions, all followed by recurrences. The main clinical findings were redness and swelling of the facial skin, upper lip ulceration, and hard palate swelling. Computed tomography showed a large hyperdense mass in right maxilla extending to right orbit and left maxillary sinus. An incisional biopsy was performed and microscopic examination showed areas of osteoid and chondroid formation surrounded by a cellular stroma. The diagnosis of osteosarcoma was established and the patient was recommended for oncologic treatment. Unfortunately, she died six months after the diagnosis due to uncontrollable local spread

Plataforma didáctica para robótica articulada por medio de una interfaz gráfica

Este artículo expone el desarrollo de una plataforma robótica didáctica. El propósito de la plataforma es realizar trabajos experimentales que permitan la ejecución y evaluación de tareas específicas relacionadas con la cinemática y control de movimiento de las articulaciones de un mecanismo robótico. Un elemento básico de la plataforma es el brazo robótico xArm-1s del fabricante Hiwonder, el cual posee una estructura articulada con seis servomotores y una tarjeta propia para su control mediante una tarjeta Arduino. Los estados de movimiento se monitorean por medio de una interfaz gráfica desarrollada en Matlab que permite el manejo de las variables utilizadas. La plataforma está dirigida a la enseñanza como una herramienta experimental que permita el análisis y compresión de cada concepto de la cinemática de la robótica articulada

Diagnosis, Prognosis and Treatment of Canine Cutaneous and Subcutaneous Mast Cell Tumors

Mast cell tumors (MCTs) are hematopoietic neoplasms composed of mast cells. It is highly common in dogs and is extremely important in the veterinary oncology field. It represents the third most common tumor subtype, and is the most common malignant skin tumor in dogs, corresponding to 11% of skin cancer cases. The objective of this critical review was to present the report of the 2nd Consensus meeting on the Diagnosis, Prognosis, and Treatment of Canine Cutaneous and Subcutaneous Mast Cell Tumors, which was organized by the Brazilian Association of Veterinary Oncology (ABROVET) in August 2021. The most recent information on cutaneous and subcutaneous mast cell tumors in dogs is presented and discussed

Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018 population-based measurement studies with 88.6 million participants

© The Author(s) 2018. Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20-29 years to 70-79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure. Results: In 2005-16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association. Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups
