OBJECTIVE To evaluate the differences in the patterns of Brazilian scientific production, published in journals that concentrate the largest production from Brazilian postgraduate programs in the area of collective health. METHODS Based on the distinction between paradigmatic and non-paradigmatic science proposed by Kuhn, the publication of articles in the main collective health journals, rel...

near-fault ground motions with long-period pulses can place severe demands on structures near an active fault. these pulse-type ground motions can be represented by pulse sequences with simple shapes. half-sinusoidal pulse sequences are used to approximate recorded ground motions and dynamic responses of sdof system under the excitation of these pulse sequences are studied. four cases are consi...

Previous research has shown that sub-population genetic algorithm is effective in solving the multiobjective combinatorial problems. Based on these pioneering efforts, this paper extends the SPGA algorithm with a global Pareto archive technique and a two-stage approach to solve the multi-objective problems. In the first stage, the areas next to the two single objectives are searched and solutio...

In South Africa, cane is delivered to the mill uniformly over the milling season and across all supply areas. This delivery schedule does not exploit the cane quality patterns, represented by the ‘recoverable value’ (RV) of sugar, which show distinct regional trends, primarily due to climate differences and the resulting differences in agronomic practices. This study, which focused on the Sezel...

Studies on spatial fertility differentials in sub-Sahara Africa normally treat the rural sector as a single and uniform geographical entity. This approach, unfortunately, tends to mask differences, which may exist between components of the rural sub-sectors. This empirical study, based on both quantitative analyses and participatory methodologies, has stratified one rural district in southweste...

Objective: Aflatoxin G1 and G2, are highly toxic and carcinogenic secondary metabolites produced by Aspergillus flavus and Aspergillus parasiticus fungi sampling was done according to "CBS" instructions from indoor and outdoor stations. Methods: In HPLC measuring, we first purified our sample of all  Aflatoxins, We used imonoaffinty columns, Fina...

Numerous studies have revealed the essential role of the left lateral temporal cortex in auditory sentence comprehension along with evidence of the functional specialization of the anterior and posterior temporal sub-areas. However, it is unclear whether task demands (e.g., active vs. passive listening) modulate the functional specificity of these sub-areas. In the present functional magnetic r...
