Effect of the type of emulsifying salt on microstructure and rheological properties of "requeijão cremoso" processed cheese spreads.

The role of different types of emulsifying salts-sodium citrate (TSC), sodium hexametaphosphate (SHMP), sodium tripolyphosphate (STPP) and tetrasodium pyrophosphate (TSPP)-on microstructure and rheology of "requeijão cremoso" processed cheese was determined. The cheeses manufactured with TSC, TSPP, and STPP behaved like concentrated solutions, while the cheese manufactured with SHMP exhibited weak gel behavior and the lowest values for the phase angle (G"/G'). This means that SHMP cheese had the protein network with the largest amount of molecular interactions, which can be explained by its highest degree of fat emulsification. Rotational viscometry indicated that all the spreadable cheeses behaved like pseudoplastic fluids. The cheeses made with SHMP and TSPP presented low values for the flow behavior index, meaning that viscosity was more dependent on shear rate. Regarding the consistency index, TSPP cheese showed the highest value, which could be attributed to the combined effect of its high pH and homogeneous fat particle size distribution

Visita à Setúbal negra (séc. XV-XVIII): desocultar a história local através da educação não-formal

O presente artigo dá conta de um roteiro sobre a presença negra em Setúbal, nos séculos XV a XVIII, concebido enquanto “aula-passeio”, espaço de educação não formal sobre o colonialismo português. Pretende-se, antes de mais, suscitar o rompimento com a narrativa lusotropicalista; entender a escravatura como um sistema complexo e parte de conflitos geopolíticos globais; mas também conduzir os participantes à “descoberta” de como os “outros” estão, afinal, em “nós”.info:eu-repo/semantics/publishedVersio

Disfagia e Disartria. Forma Invulgar de Apresentação da Miastenia Gravis

Myasthenia Gravis is an autoimmune disorder that generally presents with ocular symptoms, specially diplopia and ptosis. Dysphagia may be a manifestation of the generalised type of the disease, but rarely is its presenting feature. The authors describe a case of Myasthenia Gravis in an old patient complaining of dysphagia and dysarthria. Because Myasthenia Gravis is a potentially serious but treatable disease, we emphasize the need to consider it in the differential diagnosis of dysphagia, namely in the elderly. In fact, the disorder is probably underdiagnosed in this population group, because clinicians tend to accept other more frequent diagnosis to explain these symptoms

Short-term retrieval of water transparency from a caged-fish farm using Landsat-8/OLI images.

Abstract: The intense growth of fish farming in Brazil requires an operational monitoring of water quality. Water transparency is an important parameter to investigate the biological balance in productive waters. Empirical algorithms based on remotely sensed data can be used to monitoring the spatial and temporal variability in such productive system. This work aimed to map the water transparency in caged-fish farm from space and to evaluate the short-term impact of this activity on eutrophication. The results showed that the empirical algorithm (band ratio 443/665 nm) was satisfactory for study area (MAPE = 17.5%) and the water transparency was an indicator of algal presence in fish farms

Personality as a Predictor of Disability in Multiple Sclerosis.

As personality changes and personality disorders are frequently observed in multiple sclerosis (MS), personality may be a prognostic factor for this disease. The present study investigated the influence of personality on disability, progression, and treatment adherence in MS. Personality was assessed in 41 patients with Relapsing-Remitting MS (30 females; mean age = 42.63 years) using the NEO Personality Inventory-3rd edition. Disability was measured with the Expanded Disability Status Scale, and treatment adherence information was collected from the Swiss MS Cohort. Correlation, multiple linear and partial least square regressions were performed to examine relations between personality, disability, and treatment adherence in MS. After accounting for age and time since disease onset, our analysis revealed that Neuroticism (β = 0.32, p = 0.01) and its Vulnerability facet (β = 0.28, p < 0.05) predicted greater disability, whereas Extraversion (β = -0.25, p = 0.04) and its Activity facet (β = -0.23, p < 0.05) predicted milder disability. Regarding disability progression, correlational analysis revealed that it was negatively correlated with Extraversion (r = -0.44, p = 0.02) and the Feelings facet of Openness (r = -0.41, p = 0.03), but regressions failed to highlight any predictive links. No significant results could be demonstrated for treatment adherence. Overall, our study showed that some personality traits can impact disability in MS, indicating that these should be considered in clinical practice, as they could be used to adapt and improve patients' clinical support

The Critical Behaviour of the Spin-3/2 Blume-Capel Model in Two Dimensions

The phase diagram of the spin-3/2 Blume-Capel model in two dimensions is explored by conventional finite-size scaling, conformal invariance and Monte Carlo simulations. The model in its $\tau$-continuum Hamiltonian version is also considered and compared with others spin-3/2 quantum chains. Our results indicate that differently from the standard spin-1 Blume-Capel model there is no multicritical point along the order-disorder transition line. This is in qualitative agreement with mean field prediction but in disagreement with previous approximate renormalization group calculations. We also presented new results for the spin-1 Blume-Capel model.Comment: latex 18 pages, 4 figure

Efeito da densidade de plantio sobre a produção do primeiro ciclo da bananeira 'Pacovan'.

A banana é uma das frutas mais consumidas no mundo, sendo explorada na maioria dos países tropicais. O Brasil destaca-se como o segundo produtor mundial, ocupando a Índia a primeira colocação. Em nível nacional, a região Nordeste é a maior produtora de banana, destacando-se como principais produtores os estados da Bahia e Pernambuco (Agrianual..., 2001). No Piauí, a bananeira é cultivada sobretudo em pequenas propriedades, constituindo-se de grande importância social para a região, quer pelo seu amplo consumo em todas as camadas sociais, quer pelo fato do seu cultivo dar-se, principalmente, por pequenos produtores, gerando, dessa forma, uma quantidade significativa de emprego e renda no meio rural. Diversas densidades de plantio têm sido utilizadas, gerando grande controvérsia entre os produtores sobre qual a mais adequada e que otimize a produção de bananas. Vários autores relatam que as maiores produtividades por ciclo foram obtidas em maiores densidades (Gomes et al. 1984; Robinson & Nel, 1986; Lichtemberg et al. 1994, 1996), entretanto, Irizarry et al. (1978) não observaram efeitos significativos no primeiro ciclo de produção. Este trabalho teve por objetivo avaliar o comportamento produtivo da bananeira ?Pacovan? em diferentes densidades de plantio
