Effect of q-deformation in the NJL gap equation

We obtain a q-deformed algebra version of the Nambu-Jona-Lasinio model gap equation. In this framework we discuss some hadronic properties such as the dynamical mass generated for the quarks, the pion decay constant and the phase transition present in this model.Comment: 5 pages, 1 eps figure, to appear in Phys.

Lasso Estimation of an Interval-Valued Multiple Regression Model

A multiple interval-valued linear regression model considering all the cross-relationships between the mids and spreads of the intervals has been introduced recently. A least-squares estimation of the regression parameters has been carried out by transforming a quadratic optimization problem with inequality constraints into a linear complementary problem and using Lemke's algorithm to solve it. Due to the irrelevance of certain cross-relationships, an alternative estimation process, the LASSO (Least Absolut Shrinkage and Selection Operator), is developed. A comparative study showing the differences between the proposed estimators is provided

Modelagem tridimensional de uma escola “sustentável”: avaliação bioclimática do edifício

CIES2020 - XVII Congresso Ibérico e XIII Congresso Ibero-americano de Energia SolarRESUMO: A arquitetura contemporânea apesar de publicizar a sustentabilidade, foca o desempenho ambiental e não busca tratar a sustentabilidade holisticamente. O artigo tem como objetivo investigar a qualidade bioclimática de edifício escolar situado no litoral brasileiro (cidade de Recife-PE), que publiciza promover a sustentabilidade através do edifício. Para odesenvolvimento da pesquisa foi realizado o percurso metodológico: Coleta documental e pesquisa bibliográficado colégio; Visita ao colégio; Aprofundamento teórico sobre qualidade ambiental e arquitetura bioclimática; Análise bioclimática do colégio. O edifício foi projetado com o intuito de apresentar um bom desempenho sobre o ponto de vista ambiental, no entanto deixa a desejar quanto ao quesito consumo de energia. Constatou-se que a sustentabilidade do edifício parece ser uma estratégia de publicidade e de busca pela qualidade ambiental, do que a efetiva promoção da sustentabilidade a partir da visão holística.ABSTRACT: Contemporary architecture despite the sustainability of advertising, seal or environmental performance and does not seek to treat sustainability holistically.

Detecting respiratory bacterial communities of wild dolphins: Implications for animal health

Infectious diseases contribute to the vulnerable status of marine mammals, including respiratory illnesses. This study aimed to capture exhaled breath condensate (blow) for microbial identification from wild Indo-Pacific bottlenose dolphins Tursiops aduncus. Individual dolphins were sampled by holding a funnel connected to a 50 ml centrifuge tube over the blowhole of the animal near shore in Shark Bay (SB), Western Australia. Four individuals were sampled on 2 occasions along with seawater samples. Comparative blow and pool water samples were collected from 4 individual common bottlenose dolphins Tursiops truncatus housed in the National Aquarium (NA), Baltimore, Maryland, USA. Bacteria were identified using the V4 region of the 16S rRNA gene from extracted DNA. We identified bacteria independent of seawater in SB dolphins, which included the classes Alphaproteobacteria (26.1%) and Gammaproteobacteria (25.8%); the phyla Bacteroidetes (15.6%) and Fusobacteria (7.2%); and the genera Pseudomonas (11.5%), Pedomicrobium (4.5%), Streptobacillus (3.7%), Phenylobacterium (2.2%) and Sphingomonas (2.1%). There were broad similarities in phyla between SB and NA dolphins yet there were differences between lower taxonomic groups. A number of operational taxonomic units (OTUs) were shared between dolphin individuals, which may be a result of their genetic lineage (siblings or parentage), shared living and social interactions. A number of genera were observed in SB dolphins which have species known to be infectious in marine mammals such as Pseudomonas, Mycoplasma and Streptococcus. This study successfully characterised bacteria from DNA captured in blow from wild dolphins. The ability to capture these communities from individuals in the wild provides a novel health indicator

Caracterización química del aceite de barú y su subproducto de la región noroeste de Minas Gerais, Brasil

This study investigated baru oil and partially defatted baru flour from the northwest region of Minas Gerais, Brazil. The physicochemical characterization of the oil was made by determining the fatty acid profile using gas chromatography, lutein, and α- and β- carotenes by means of high-performance liquid chromatography, and total carotenoids by spectrophotometry. The flour was analyzed for its chemical composition, fiber, and mineral contents. Baru oil presented excellent quality parameters and high contents in unsaturated fatty acids and carotenoids. The flour showed relevant levels of proteins, lipids, and dietary fiber, in addition to having representative mineral contents for food such as manganese, magnesium, and copper. Thus, baru oil and the by-product of its extraction offer a rich chemical composition, and their application may add nutritional value to foods in addition to reducing negative environmental impacts.En este estudio se investigó el aceite de barú y la harina de barú parcialmente desengrasada de la región noroeste de Minas Gerais, Brasil.

Liver Resections for Metastases from Intraabdominal Leiomyosarcoma

This paper discusses liver resection for intraabdominal leiomyosarcoma metastases as a therapy for carefully selected patients. Of the 83 hepatectomies performed from 1992 to 1996, five were resections for liver metastases due to intraabdominal leiomyosarcoma, in 3 patients. The surgical indication was single liver metastases, without any evidence of extrahepatic disease. No mortality occurred during surgery and the longest survival was 38 months. We concluded that liver resection for leiomyosarcoma metastases can be performed, allowing a long term survival in an occasional patient

Underwater energy harvesting to extend operation time of submersible sensors

A linear electromagnetic energy harvesting device for underwater applications, fabricated with a simple manufacturing process, was developed to operate with movement frequencies from 0.1 to 0.4 Hz. The generator has two coils, and the effect of the combination of the two coils was investigated. The experimental study has shown that the energy capture system was able to supply energy to several ocean sensors, producing 7.77 mJ per second with wave movements at 0.4 Hz. This study shows that this energy is enough to restore the energy used by the battery or the capacitor and continue supplying energy to the sensors used in the experimental work. For an ocean wave frequency of 0.4 Hz, the generator can supply power to 8 sensors or 48 sensors, depending on the energy consumed and its optimization.This work is co-funded by the project K2D-Knowledge and Data from the Deep to Space with reference POCI-01-0247-FEDER-045941, co-financed by European Regional Development Fund (ERDF), through the Operational Program for Competitiveness and Internationalization (COMPETE2020) and by the Portuguese Foundation for Science and Technology-FCT under MIT-Portugal Program.

The Impact Of Eeg In The Diagnosis And Management Of Patients With Acute Impairment Of Consciousness [impacto Do Eeg No Diagnóstico E Conduta Dos Pacientes Com Alteração Aguda Do Estado Da Consciência]

Objectives: To assess the frequency of electroencephalogram (EEG) requests in the emergency room (ER) and intensive care unit (ICU) for patients with impairment of consciousness (IC) and its impact in the diagnosis and management. Methods: We followed patients who underwent routine EEG from ER and ICU with IC until discharge or death. Results: During the study, 1679 EEGs were performed, with 149 (8.9%) from ER and ICU. We included 65 patients and 94 EEGs to analyze. Epileptiform activity was present in 42 (44.7%). EEG results changed clinical management in 72.2% of patients. The main reason for EEG requisition was unexplained IC, representing 36.3% of all EEGs analyzed. Eleven (33%) of these had epileptiform activity. Conclusion: EEG is underused in the acute setting. The frequency of epileptiform activity was high in patients with unexplained IC. EEG was helpful in confirming or ruling out the suspected initial diagnosis and changing medical management in 72% of patients.7013439Bauer, G., Trinka, E., Nonconvulsive status epilepticus and coma (2010) Epilepsia, 51, pp. 177-190Niedermeyer, E., Silva, F.H.L., (1999) Electroencephalography: Basic Principles, Clinical Applications and Related Fields, , Mariland, USA: William & WilkinsPraline, J., Grujic, J., Corcia, P., Emergent EEG in clinical practice (2007) Clin Neurophysiol, 118, pp. 2149-2155Young, G.B., Jordan, K.G., Doig, G.S., An assessment of nonconvulsive seizures in the intensive care unit using continuous EEG monitoring: An investigation of variables associated with mortality (1996) Neurology, 47, pp. 83-89Towne, A.R., Waterhouse, E.J., Boggs, J.G., Prevalence of nonconvulsive status epilepticus in comatose patients (2000) Neurology, 54, pp. 340-345Vespa, P.M., O'Phelan, K., Shah, M., Acute seizures after intracerebral hemorrhage: A factor in progressive midline shift and outcome (2003) Neurology, 60, pp. 1441-1446Quigg, M., Shneker, B., Domer, P., Current practice in administration and clinical criteria of emergent EEG (2001) J Clin Neurophysiol, 18, pp. 162-165Drislane, F.W., Lopez, M.R., Blum, A.S., Schomer, D.L., Detection and treatment of refractory status epilepticus in the intensive care unit (2008) J Clin Neurophysiol, 25, pp. 181-186Misra, U.K., Kalita, J., Seizures in encephalitis: Predictors and outcome (2009) Seizure, 18, pp. 583-587Alroughani, R., Javidan, M., Qasem, A., Alotaibi, N., Non-convulsive status epilepticusthe rate of occurrence in a general hospital (2009) Seizure, 18, pp. 38-42Kaplan, P.W., The EEG in metabolic encephalopathy and coma (2004) J Clin Neurophysiol, 21, pp. 307-318Bahamon-Dussan, J.E., Celesia, G.G., Grigg-Damberger, M.M., Prognostic significance of EEG triphasic waves in patients with altered state of consciousness (1989) J Clin Neurophysiol, 6, pp. 313-319Firosh, K.S., Ashalatha, R., Thomas, S.V., Sarma, P.S., Emergent EEG is helpful in neurology critical care practice (2005) Clin Neurophysiol, 116, pp. 2454-2459Duffy, F.H., Iyer, V.G., Surwillo, W.W., (1989) Clinical Electroencephalography and Topographic Brain Mapping, , New York: Spring-VerlagGuideline 6: A proposal for standard montages to be used in clinical EEG (2006) J Clin Neurophysiol, 23, pp. 111-117. , American Clinical Neurophysiology SocietyVarelas, P.N., Spanaki, M.V., Hacein-Bey, L., Hether, T., Terranova, B., Emergent EEG: Indications and diagnostic yield (2003) Neurology, 61, pp. 702-704Kilbride, R.D., Costello, D.J., Chiappa, K.H., How seizure detection by continuous electroencephalographic monitoring affects the prescribing of antiepileptic medications (2009) Arch Neurol, 66, pp. 723-728van Cott, A., Brenner, R.P., Technical advantages of digital EEG (1998) J Clin Neurophysiol, 15, pp. 464-475So, E.L., Interictal epileptiform discharges in persons without a history of seizures: What do they mean?

Social inequalities in the food consumption profile of the brazilian population : national health survey, 2013

É amplamente reconhecido que elevada concentração de renda prevalece no Brasil e que a posição socioeconômica dos segmentos sociais exerce influência nas condições de vida e saúde, incluindo a qualidade da alimentação. Medir a magnitude das desigualdades sociais no perfil da qualidade alimentar da população brasileira. Analisaram-se dados da amostra de 60.202 adultos da Pesquisa Nacional de Saúde de 2013. Foram estimadas as prevalências de indicadores de qualidade alimentar segundo sexo, raça/cor, renda, escolaridade e posse de plano de saúde. Razões de prevalência foram estimadas por meio de regressão múltipla de Poisson. Maior prevalência de consumo de alimentos saudáveis foi verificada no sexo feminino, entre os brancos e no grupo de melhor nível socioeconômico. Entretanto,para alguns alimentos considerados não saudáveis, como doces, sanduíches, salgados e pizzas, também foi observada maior prevalência nos segmentos sociais mais favorecidos, nas mulheres e nos brancos, expressando a concomitância de escolhas alimentares saudáveis e não saudáveis. Desigualdade de maior magnitude foi observada quanto à comparação do consumo de leite desnatado e semidesnatado segundo renda (razão de prevalência - RP=4,48). Além de expressiva desigualdade social no perfil alimentar dos brasileiros, foram detectados perfis mistos, incluindo alimentos saudáveis e não saudáveis, sinalizando a necessidade de monitoramento e de intervenções de promoção de alimentação saudável que levem em conta as desigualdades sociais e as contradições no consumo alimentar222CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQnão tem817122/2015High income concentration prevails in Brazil and socioeconomic status influences living and health conditions, including dietary quality. Objective: To measure the magnitude of social inequalities in the food quality profile of the Brazilian population. We analyzed data from 60,202 adults who participated in the 2013 National Health Survey. The prevalence of indicators of food quality was estimated according to gender, ethnicity, income, schooling, and health insurance. We calculated prevalence ratios using multiple Poisson regression. Healthy food consumption was more prevalent among females, white people, and individuals with higher socioeconomic status. However, we also found a higher prevalence of some foods considered unhealthy, such as sweets, sandwiches, snacks, and pizzas, among the most favored social segments, in women, and white people, expressing the concomitance of healthy and unhealthy eating habits. The comparison between the consumption of skim and low-fat milk according to income (prevalence ratio – PR = 4.48) presented the most significant difference. In addition to the expressive social inequality identified in the Brazilian food profile, mixed patterns were detected, including healthy and unhealthy foods. These results point out the need for monitoring and promoting healthy eating habits, taking into account the social inequalities and contradictions concerning food intakeMinistério da Saúd

Optical Absorption Measurements In A New Composite Material By Combined Photoacoustic And Beam Transmission Techniques

The absorption coefficient of a highly absorbing (β>105 cm-1) new composite produced in our laboratory, namely manganese dioxide surface-impregnated polyethylene (MnO2-PE) film, has been measured in the visible range. We have employed a combination of concurrently taken photoacoustic and beam transmission data. This combination proved to be an effective means for the optical evaluation of highly absorptive samples which dispenses with the need for prior knowledge of the sample reflectivity. Theoretical interpretation of MnO2-PE absorption profile, with due account of the processes underlining the photoacoustic signal generation, reveals a semiconductor behavior with an estimated effective gap wavelength of 8050 Å. Technical implications of the availability of these highly absorptive flexible films are briefly considered.5794431443
