Magalh?es, Joaquim Romero;
Tempo , 2009, DOI: 10.1590/S1413-77042009000200009
Abstract: the capitation or individual tax was a collection procedure equivalent to one fifth or the gold extraction in minas gerais. this 1735 royal imposition lasted till 1750 and caused strong opposition from the municipalities in that region. many attempts were made to abrogate it until the new king d. josé decided to revoke it. it is the aim of this article to survey the capitation challenge process.

Abstract: the portuguese atlantic islands was during the maritime expansion a strategic point for the deployment of a system of colonization based in the commercial exploration of certain primary goods. the sugar was one of them. while in some islands the sugar cane has proved impracticable, in others it was a source of income, mainly with the exportation of the product to europe. the slavery was one of the essential foundations for the success of this system. latter it was transferred to brazil, where the colonization was more economically advantageous.

Deformation of Gabor systems
Karlheinz Gr?chenig,Joaquim Ortega-Cerdà,José Luis Romero
Mathematics , 2013, DOI: 10.1016/j.aim.2015.01.019
Abstract: We introduce a new notion for the deformation of Gabor systems. Such deformations are in general nonlinear and, in particular, include the standard jitter error and linear deformations of phase space. With this new notion we prove a strong deformation result for Gabor frames and Gabor Riesz sequences that covers the known perturbation and deformation results. Our proof of the deformation theorem requires a new characterization of Gabor frames and Gabor Riesz sequences. It is in the style of Beurling's characterization of sets of sampling for bandlimited functions and extends significantly the known characterization of Gabor frames "without inequalities" from lattices to non-uniform sets.
Development of a “Space-Saving Model” for a One-Family Dwelling Case Study of Japanese Architecture with Space Limitations  [PDF]
Jorge Romero
Journal of Building Construction and Planning Research (JBCPR) , 2015, DOI: 10.4236/jbcpr.2015.34020
Abstract: The rapid globalization of building standards and codes in regards of contemporary housing and the growth of populations during this century demands an immediate response from designers in terms of space rationalizing to fulfill the forthcoming lack of architectural habitat on earth. The differences in culture imply a difference in the way of living, and the way of living indicates a contrast in the way of designing houses. A western house does not need an extra room covered with tatami mats for relaxation as a modern Japanese home would most likely do, as a separate living-like space. Organizations, among others, like CABO (Council of American Building Officials) and, in our specific case study, BCJ (Building Center of Japan) together with BRI (Building Research Institute) try to overcome these differences to provide better housing conditions to the world through the formulation of global designing and building standards. International publications like UBC (Uniform Building Code), IBC (International Building Code), OTFDC (One and Two Family Dwelling Code) and BSLJ (Building Standard Law of Japan) have also played an important role to globalize safety and design codes to better understand global housing under normal conditions. However, space limitations and concentration of human masses in mega cities result in a crucial new consideration: the urgent need of investigating the possibilities of rationally living within less space. Minimums provided by most codes do not take into account the space issue and overpopulation of large cities. Providing with some design recommendations for one-family dwellings has been the departure point and main motivation to carry out this case study based on actual buildings with the lack of space conditioning in a country where these conditions turn into reality.
Speech Assessment for UIDE EFL Students: The IPA Case

Abstract: This Teaching English as the target second language involves several considerations which have to do with both the source language of speakers and the kind of training these students go through. In this particular case study, I have considered native speakers of Spanish who study English as a second language and identified, through two vowel sounds forming a minimal pair, that phonemes of General American English which are more likely to be mispronounced, is not only due to the fact that the English vowel system is more complex than that of Spanish, but also, and most important for this particular case study, that training is not consistent in contrastive exercising as it is in distribution exercising. In fact the English system has 20 vowel phonemes in Received Pronunciation, from 14 to 16 vowel phonemes in General American English and even 20 to 21 vowel phonemes in Australian English, while Spanish has only 5 vowel phonemes. The findings of this research account for the conclusion that exercising reinforcement need to be addressed and focused not only on the phonemes of the English vowel system which native speakers of Spanish have more trouble with, but also and more relevant in this research, that new and creative distribution exercising must be included in textbooks to help students master the English vowel sounds in order to avoid accent due to Spanish interference through quality English teaching.

Journal of Electromagnetic Analysis and Applications (JEMAA) , 2013, DOI: 10.4236/jemaa.2013.59058
Abstract:

Metamaterial one-dimensional periodic structures are composed of split-ring resonators, which can display electric permittivity and magnetic permeability simultaneously negative, are studied experimentally. In the present study, each resonator is made up of two concentric circular copper rings patterned on a substrate of kapton, with slits diametrically opposite each other and with the line of the splits along the longitudinal direction of the periodic array containing seven split rings evenly spaced. The experiments consist in inserting the metamaterial slab into a square waveguide of side length 6 mm, corresponding to a cutoff frequency of 25 GHz. Transmission bands due to magnetic and electrical responses are identified for slits with aperture widths of 1 mm and 2 mm, centered at 5.67 and 6.12 GHz frequencies, respectively, values well below the 25 GHz frequency cutoff, so characterizing a medium with negative permeability and

Abstract: background: postoperative cerebrospinal fluid (csf) fistula is the most serious complication after transsphenoidal surgery. objective: to analyze the incidence of csf fistula after endoscopic transsphenoidal surgery for tumor removal in sellar region; to discuss associated factors and methods used for sellar closure. method: retrospective study of 67 patients (73 surgeries) operated via transsphenoidal endoscopy at hospital vall d'hebron and hospital clinic of the universidad de barcelona, spain. the data collected included: age, sex, hospitalization stay, suprasellar extension of the lesion, type of tumor, evidence of intraoperative csf fistula, complications of postoperative csf fistula, previous surgery and radiotherapy. results: six patients (8.2%) had postoperative csf fistula, and their average hospitalization was 5 days longer with resulting complications: two of whom had pneumoencephalus and two with meningitis. no association was found between the data collected and postoperative csf fistula. conclusion: the rate of csf fistula after endoscopic transsphenoidal surgery from the present study is contained within the literature. unlike other reports, no association between the variables and postoperative csf fistula was found in this report.
Hydraulic conductivity and soil-sewage sludge interactions
Ferreira, Silvio Romero de Melo;Oliveira, Joaquim Teodoro Rom?o de;Messias, Arminda Saconi;Silva, Hannelore Alves e;Nascimento, Aline Elesb?o do;Feitosa, Maria Célia Alves;
Revista Brasileira de Ciência do Solo , 2011, DOI: 10.1590/S0100-06832011000500011
Abstract: one of the main problems faced by humanity is pollution caused by residues resulting from the production and use of goods, e.g, sewage sludge. among the various alternatives for its disposal, the agricultural use seems promising. the purpose of this study was to evaluate the hydraulic conductivity and interaction of soil with sandy-silty texture, classified as spodosols, from the experimental station itapirema - ipa, in goiana, state of pernambuco, in mixtures with sewage sludge from the mangueira sewage treatment station, in the city of recife, pernambuco at rates of 25, 50 and 75 mg ha-1. tests were conducted to let water percolate the natural saturated soil and soil-sludge mixtures to characterize their physical, chemical, and microstructural properties as well as hydraulic conductivity. statistical data analysis showed that the presence of sewage sludge in soils leads to an increase of the < 0.005 mm fraction, reduction in real specific weight and variation in optimum moisture content from 11.60 to 12.90 % and apparent specific dry weight from 17.10 and 17.50 kn m-3. in the sludge-soil mixture, the quartz grains were covered by sludge and filling of the empty soil macropores between grains. there were changes in the chemical characteristics of soil and effluent due to sewage sludge addition and a small decrease in hydraulic conductivity. the results indicate the possibility that soil acidity influenced the concentrations of the elements found in the leachate, showing higher levels at higher sludge doses. it can be concluded that the leaching degree of potentially toxic elements from the sewage sludge treatments does not harm the environment.
