Abstract:


Introduction: Studies on attitudes and practices are increasingly used but not specifically related to the motivations for the use of reproductive health care among women of fertile age, living in urban areas and in different social contexts. Objectives: The aim of this study was to estimate the associations between the variables of social status (degree of poverty in the studied groups) and the variables of fecundity (representations, tensions, practices and control of fertility) and, in addition, to compare access to health care in the different studied groups, assessing the association between use of maternal health care and poverty in urban areas. Design: A case-control study was conducted in the Municipality of Lisbon, Portugal, with a total sample of 1513 women of fertile age: 499 cases of women considered very poor were selected from the database of beneficiaries of RSI (Social Welfare Payment for Inclusion); 1014 controls (two controls for each selected case), divided as 507 poor women selected from the other beneficiaries of Santa Casa da Misericórdia in Lisbon and 507 non-poor women selected from four Health Centers from the Municipality of Lisbon, Portugal. A total of 1054 women answered the questionnaire: 304 cases (response rate of 61%) and 750 (response rate of 74%) controls. The statistical analysis involved descriptive analysis and multinomial logistic regression. Results: The analysis confirms the association between poverty and patterns and representations of fecun

dity regarding pregnancy planning. The results of this study thus show the existence of different distributions on several variables and the gradients of poverty. Regarding access to health care, the major impact of poverty on women

Development of Mathematical Models for the Analysis of Hepatitis Delta Virus Viral Dynamics
Bruno C. de Sousa,Celso Cunha
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0012512
Abstract: Mathematical models have shown to be extremely helpful in understanding the dynamics of different virus diseases, including hepatitis B. Hepatitis D virus (HDV) is a satellite virus of the hepatitis B virus (HBV). In the liver, production of new HDV virions depends on the presence of HBV. There are two ways in which HDV can occur in an individual: co-infection and super-infection. Co-infection occurs when an individual is simultaneously infected by HBV and HDV, while super-infection occurs in persons with an existing chronic HBV infection.
Synthesis of ZSM-22 in Static and Dynamic System Using Seeds  [PDF]
Lenivaldo V. de Sousa Júnior, Antonio O. S. Silva, Bruno J. B. Silva, Soraya L. Alencar
Modern Research in Catalysis (MRC) , 2014, DOI: 10.4236/mrc.2014.32007
Abstract:

ZSM-22 was synthesized using various sources of silica, organic template 1,6-diaminohexane, under hydrothermal conditions, with and without agitation during crystallization. Subsequently, the crystallized material was used as seeds to accelerate the crystallization process. Characterization of the ZSM-22 samples was performed by XRD, ATG/DTG and FT-IR. It was found that it is possible to synthesize ZSM-22 employing colloidal silica and pyrolytic silica as silicon sources only if the system is stirred during crystallization. The crystallization time for these systems was 13 hours, longer times of crystallization do not significantly increase the crystallinity of the sample. The addition of seeds significantly accelerates the crystallization of ZSM-22, reducing the crystallization time to only 7 hours, with stirring and with systems employing colloidal silica.

Abstract: the innovation contributes to business success and increased competitive advantage, one of the concepts that have deserved more attention among researchers in the field of management. innovation is not exclusive of tangible products or services and can naturally extend to the process itself, the organization or marketing. although it is not easy to gather a universal concept for innovation, do not seem to be no doubt that its importance is such that allows the company to build on the foundations of this future development, regardless of past success. this work (work in progress) has as its central purpose the study of process innovation in the supply outlook for tourism, given its importance in achieving business success. the recognition of its value assumes it as a challenge, making it necessary to distinguish with product, marketing and organizational innovation, either in substance or in the organizational competencies. will be presented in this work, a brief description (as well as evolution of the concept) as a way of contextualizing and, then, clarified the distinction between the concepts process innovation and innovation process. search will bring together the key distinguishing features from the perspective of tourism as a means of achieving competitive advantage for business. we will also discuss implications for management and future studies.
Biotechnological Reuse of Fruit Residues as a Rational Strategy for Agro-industrial Resources
de Araújo Sousa,Bruno Alexandre; Targino Pinto Correia,Roberta;
Journal of technology management & innovation , 2010, DOI: 10.4067/S0718-27242010000200010
Abstract: brazil, one of the largest agricultural producers in the world, has managed in recent years to significantly improve its production. however, in response to this advance in the agro-industrial sector, the generation of agro-industrial residues or sub-products has also increased, and its improper disposal may have a strong environmental impact, in addition to causing losses of raw materials and energy. in this context, the use of these residues as substrates for the production of high value-added compounds using semi-solid fermentation has been studied. thus, the aim of this study was the physical-chemical characterization of pineapple and guava residues and their potential reuse in semi-solid cultivation. the results show that both residues are sources of bio-usable nutrients after a number of operational parameters of the bioprocess of choice are adjusted.
Determination of cobalt in wine and must by electrothermalatomization atomic absorption spectrometry: analyticalmethod development and validation
Catarino,S.; Neves,A.; Sousa,R. Bruno de;
Ciência e Técnica Vitivinícola , 2009,
Abstract: an electrothermal atomization atomic absorption spectrometry method was optimized to quantify cobalt in musts and wines, especially within quality control scope. as far as wine samples are concerned, the method involves reduced risk of contamination by eliminating prior treatment other than dilution (1:2). for must samples a pre-treatment is needed, in order to destroy the organic matter that could interfere with the analytical determination. a conventional thermal program (with pyrolysis step), with and without matrix modifier [mg(no3)2], was developed and optimized. pyrolysis and atomization curves were studied using a co standard solution, must and wine samples. the analytical figures of merit of the method such as linearity of the calibration curve, specificity (standard additions test), accuracy, analytical limits and precision were studied using wine samples. the linear dynamic range under optimized conditions was 0.4-10.0 μg/l. the recoveries were between 87% and 98% for all of the wines and addition levels used in the test. the method presents a very satisfactory specificity for red wines, while matrix effect was observed for white wines. the limit of detection in undiluted wines was 0.8 μg/l. repeatability was lower than 0.7 μg/l (rsd < 5%). for accuracy evaluation, co content in six wine samples and one co standard solution, from an international collaborative trial, was determined by etaas and icp-ms with comparable results (in general the differences were lower than 5%). bearing in mind that must samples are previously digested, it is expected that the method performance parameters are at least as favourable as those observed with wines.

Abstract: El suceso empresarial y el aumento de las ventajas competitivas están asociados a la innovación que tiende a afirmarse como uno de los conceptos que más atención ha merecido de los investigadores del área de gestión. La innovación no es exclusiva de los productos tangibles o servicios, pudiendo naturalmente extenderse al propio proceso, a la organización o al marketing. No obstante, aunque no sea fácil reunir un concepto universal para la innovación, parecen no restar dudas de que su importancia es tal que permite a la empresa construir en el presente las bases de su desarrollo futuro, independientemente del suceso pasado. El presente trabajo (work in progress) tiene como objeto central el estudio de la innovación de procesos (process innovation) en la perspectiva de la oferta de turismo, dada su importancia en el alcance del éxito empresarial. El reconocimiento de su valor la asume como un desafío, tornándose necesaria la distinción entre la innovación de productos, de marketing y organizacional, ya sea en la esencia o en lo que concierne a las competencias organizacionales. En este sentido se presenta en este trabajo una breve caracterización (así como la evolución del concepto) como forma de contextualización siendo aclarada la distinción de los conceptos process innovation e innovation process. Se intentará reunir los principales aspectos distintivos, en una perspectiva de oferta turística como forma de alcanzar ventajas competitivas a nivel empresarial. Al mismo tiempo serán discutidas las implicaciones para la gestión y para estudios futuros.
