RESUMOA grande heterogeneidade dos Resíduos Sólidos Urbanos (RSU) faz com que estes apresentem uma composição bastante variável, podendo muitas vezes, serem comparados aos resíduos industriais por possuírem substâncias a bases de metais pesados e outros componentes tóxicos que apresentam riscos a saúde e ao meio ambiente. Assim, a busca por alternativas tecnológicas para manejo adequado dos resíduos e entendimento do seu comportamento após destinação final, tem feito com que cada vez mais estudos sejam desenvolvidos para esse fim. Exemplo disso são os estudos realizados em células experimentais, feitos com o intuito de simular o comportamento de uma célula de aterro sanitário, entendendo todas as reações que ocorrem em seu interior sob condições controladas. O objetivo desse trabalho é avaliar o potencial tóxico dos RSU da cidade de Campina Grande -PB, presentes em uma célula experimental. O experimento consistiu em uma célula experimental dotada de toda instrumentação presente em uma célula de um aterro real. O monitoramento da célula foi feito durante um período de dois anos, sendo realizada a caracterização inicial dos resíduos no dia do seu preenchimento, posteriormente amostras mensais de resíduos foram coletadas. Os resultados obtidos mostraram que os RSU foram classificados como resíduos perigosos, por conterem em sua composição elevados teores de elementos traços como: Alumínio, Manganês e Níquel. Por fim, concluiu-se que a presença desses elementos juntamente com o nitrogênio amoniacal presente nos RSU não interferiu no processo de biodegradação, no entanto contribuiu para o efeito fitotóxico dos resíduos sólidos.

Thus, the search for alternative technologies for proper waste management and understanding of their behavior after disposal, has made more and more studies are developed for this purpose. Examples are studies in experimental cells, made in order to simulate the behavior of a landfill cell, understanding all the reactions that occur inside under controlled conditions. The aim of this study is to evaluate the toxic potential of MSW in the city of Campina Grande -PB, present in an experimental cell. The experiment consisted on the construction of an experimental cell that simulates a fullscale landfill. The monitoring of the cell was made during a period of 2 years, and held the initial characterization of the waste on the day of its completion later monthly samples of waste were collected. The results showed that the MSW were classified as hazardous waste because they contain in their composition high

e14033 Background: In 2015, in our outpatient clinic, we implemented a breast cancer interdisciplinary team with the goal of identifying risk factors for chemotherapy delay. Evaluation of individual cases and care plans were made by a medical oncologist, clinical pharmacologist, psychologist, dietician and oncology nurse. Methods: 81 patients with breast cancer in neoadjuvant/adjuvant chemotherapy were prospectively evaluated from July 2018 until July 2019 for clinical risk: age, anthracyckine use, presence of symptoms grade >3, ASGPPP questionnaire for nutritional risk, psychological risk for pre existent issues or induce by treatment and IRPO questionnaire for screening, nursing evaluation for comunication, organization and understanding issues, and pharmacologist evaluation of polypharmacy and unknown drugs or routine use. Results: Of 81 patients evaluated and had finish treatment, 55 pts (67.9%) received adjuvant chemotherapy. Median age was 57.9 years (range:29-90.6y). We defined as risk factors for delay chemotherapy treatment: anthracycline-based chemotherapy (9.34 vs 2.58 d p:0.002), psychological risk (both risks combined) (8.1 vs 4.7 p:0.047), comunication, organization and understanding issues (15.25 vs 5.83 d p: 0.004), and unknown drugs that routinely uses (11 vs 5.34d p:0.012). Patients who needed extra nutritional and psychological appointment had greater delay in chemotherapy (Dietician: 9.636 vs 4.7 d P:0.01; Psyc: 9.1 vs 4.2d p:0.008). Conclusions: The chemotherapy scheme, psychological risk, difficulty in understanding and organizing, and unaware of the drugs used routinely uses were high risk factors for delayed chemotherapy and these patients should be handled more carefully.

This paper reports on the synthesis of Zn 1-x Mn x Te nanocrystals (NCs) (with 0 B x B 0.800) within a PZABP glass system (P 2 O 5 -ZnOAl 2 O 3 -BaO-PbO) using the fusion method. The asgrown samples were investigated by optical absorption measurements, atomic force microscopy, X-ray diffraction, and Raman spectroscopy.

We discuss the generation of various reproduction ratios or numbers to monitor the outbreak of Covid-19 or other epidemics and examine the effects of intervention/relaxation measures. A detailed SEIR algorithm is described for their computation, with applications given to the current Covid-19 outbreak in several countries in America (Argentina, Brazil, Mexico, US) and Europe (France, Italy, Spain and UK).

Nautilus-shaped dynamic craniotomy: a new surgical technique and preliminary resultsNautilus: craniotomia dinâmica -nova técnica cirúrgica e resultados preliminares ABSTRACT Introduction: Considering that craniosynostosis is a suture-related condition, the main challenge for its treatment is the fact that the brain is located in a closed compartment that does not have the required adaptability to accommodate its growth. The goal of treat ment is to restore stenotic suture adaptability and correct the compensatory cranial deformity. This paper proposes the combined use of spiral osteotomy with distraction osteogenesis by the use of distracting springs to remodel craniofacial defects caused by craniosynostosis. Methods: Between July 2010 and July 2012, 10 patients with craniosynostosis were treated: 5 with oxycephaly, 3 with scaphocephaly, 1 with turricephaly, and 1 with trigonocephaly. The treatment consisted of the application of Lauritzen springs to correct the primary craniosynostosis defect in combination with a nautilus-shaped spiral craniotomy at the secondary deformation sites without dural detachment. Results: Resolution of cranial deformity and remission of the clinical signs of intracranial hypertension were observed. None of the patients had complications such as cerebrospinal fluid fistula, local infection, seroma, or hematoma. Conclusions: The combined use of spiral osteotomy with spring-mediated distraction or contraction enables active reshaping of the skull and facilitates accommodation of the brain by the cranial cavity.

RESUMOIntrodução: Considerando-se que as craniossinostoses são afecções basicamente suturais, o fato de o cérebro estar aprisionado em um compartimento fechado, que não possui a complacência necessária para acompanhar seu crescimento, se constitui no desafio principal de seu tratamento. O objetivo do tratamento é restabelecer a complacência da sutura estenótica e corrigir a deformidade craniana compensatória. Este trabalho propõe a associação de osteotomia helicoide à distração osteogênica proporcionada pelo uso das molas distratoras para remodelar defeitos craniofaciais causados por craniossinostoses. Método: Entre julho de 2010 e julho de 2012, foram tratados 10 pacientes portadores de craniossinostoses, sendo 5 oxicefalias, 3 escafocefalias, 1 turricefalia e 1 trigonocefalia. O tratamento consistiu na aplicação de molas de Lauritzen, para corrigir a deformidade primária da craniossinostose, com a associação de craniotomia helicoide em forma de Nautilus nos sítios de deformação secundária do crânio, sem descolamento dural. Resultados: Foi observada resolução da deformidade craniana e remissão dos sinais clínicos de hipertensão intracraniana. Nenhum
