P. F. F. Martins, C. A. Morais, F. S. Lameiras, R. O. Albuquerque
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2017, DOI: 10.4236/jmmce.2017.54013
Abstract: A study of silica and iron recovery from the iron ore concentration tailing is presented. The residue is composed of 40.1% Fe, 33.4% SiO2, 8.31% Al2O3, 0.08% P, and 0.34% MnO. The developed process of silica and iron recovery consisted of size classification, magnetic separation, and removal of impurities by leaching. A concentration of SiO2 from 33.4% to 67.0%, with 60.0% of mass reduction, was achieved by size classification. After magnetic separation, the SiO2 grade increased from 67.0% to 95.0%, in non-magnegtic fraction and iron increased from 40.1% to 60.2% in magnetic fraction. The iron content in magnetic fraction achieved the commercial grade. In order to increase the content of silica, the impurities removal from the non-magnetic fraction was studied. The leaching agents investigated were HCl, H2SO4, HNO3, HF, C6H8O7, (COOH)2.2H2O and NaOH. A concentration of 98.0% SiO2 was attained with the acid digestion.
Promotores de permea??o para a libera??o transdérmica de fármacos: uma nova aplica??o para as ciclodextrinas
Martins, Maria Rita Fernandes Morais;Veiga, Francisco;
Revista Brasileira de Ciências Farmacêuticas , 2002, DOI: 10.1590/S1516-93322002000100004
Abstract: the present work is a short revision about transdermal permeation enhancers, their mechanism of action including some examples. routes of permeation across the skin and transdermal delivery are also described. we focus cyclodextrins and their derivatives, structure, chemical properties, formation of inclusion complexes and their action as excipients in transdermal drug delivery systems. cyclodextrins are a very important group of excipients used in pharmaceutical technology. one of the most extraordinary properties of cyclodextrins is their ability to increase transdermal drug delivery without affecting the barrier function of the skin.
Tuberous sclerosis complex
Rodrigues, Daniela Araujo;Gomes, Ciro Martins;Costa, Izelda Maria Carvalho;
Anais Brasileiros de Dermatologia , 2012, DOI: 10.1590/S0365-05962012000200001
Abstract: tuberous sclerosis complex, also known as epiloia or bourneville-pringle disease is an autosomal dominant neurocutaneous syndrome with variable clinical expression. it is a multisystem disorder that may be associated with hamartomas in multiple organs in an unpredictable manner. the dermatologist plays an essential role in the history of the disease, since skin manifestations represent the most prevalent clinical features, enabling early diagnosis and intervention in its natural course. this article aims to inform the scientific community about advances made in the study of genetics and molecular biology. recent findings regarding stimulation of tumor growth have been changing the history of this condition, making therapeutic trials with topical and systemic drugs possible. knowledge of these topics enables better management of the patients affected, since tissue replacement by tumors can result in significant morbidity and mortality.

Abstract: in acclimatization processes, the environment control takes over a part of vital importance, since in in vitro condition banana seedlings do not efficiently operate the absorption of light, water and nutrients. therefore, they should be submitted to controlled environments under feasible conditions of luminosity, temperature (around 28oc, with minimum of 18oc and maximum of 34oc), and relative humidity above 75%. for this purpose, it was installed five mini tunnels with controlled temperature and relative humidity. for the control of temperature it was used pad-fan evaporative coolers at 28/25oc. for the control of relative humidity it was used fogging during the day at 75% under intermittence of 6s at each 40s. for temperature and relative humidity monitoring, it was installed three aspirate psychrometers in each mini tunnel connected to a data logger for daily acquisition every 60s. temperature and relative air humidity were adequate for plants development, however significant differences were observed between the different environment conditions. for luminosity study, under transparent plastic film (low density polyethylene) of 100μm thickness, it was used four meshes with average shading in the par spectrum band (400 to 700nm) of 69.92%, 50.73%, 29.73%, and 57.77%, being the first three in red color (with top level at 580nm, and abrupt reduction after that), the fourth mesh was black (linear behavior). the fifth tunnel had only transparent plastic film, showing 12.74% of solar radiation interception. these values were obtained from paired samples (mesh and plastic film) for the first four tunnels, and only the transparent plastic film for the last, using a spectral radiometer (400 to 1100nm), with spectral resolution of 2nm. inside and outside of each environment it was obtained global and par irradiance by using calibrated photovoltaic sensors at 9:00, 12:00, and 3:00, under clean and cloudy sky, during the summer of 2004/05, and winter of 2005. the red mesh pr

Abstract: banana plantlets obtained by micropropagation need to be submitted to a period of acclimatization since they do not use light, water, and nutrients in an efficient way. the acclimatization must be carried out under greenhouse conditions where temperature, light, and air humidity are adequate for a gradual hardening of the plantlets. in this study, the development of banana plantlets was evaluated during acclimatization under a full light condition including covered surfaces with red shade cloth (70%, 50%, and 30% shade) and black shade cloth (50% shade), both under a transparent plastic film of 100 μm. temperature, relative air humidity, irrigation, and nutrition conditions were also controlled. physical and physiological parameters were recorded at various stages in the greenhouses after three, six, and nine weeks and also after seven weeks of transplanting to field conditions. treatments were hierarchically graded according to their statistic classification. combined results indicated superior outcomes of plantlets maintained under black 50% shade cloth for nine weeks, both in the summer and winter seasons. similar results, but in a shorter time, were obtained with plantlets cultivated under red 70% shade cloth, for six weeks in the summer.
Assessing the Impact of Using Different Land Cover Classification in Regional Modeling Studies for the Manaus Area, Brazil  [PDF]
Sameh Adib Abou Rafee, Ana Beatriz Kawashima, Marcos Vinícius Bueno de Morais, Viviana Urbina, Leila Droprinchinski Martins, Jorge Alberto Martins
Journal of Geoscience and Environment Protection (GEP) , 2015, DOI: 10.4236/gep.2015.36013
Abstract:

Land cover classification is one of the main components of the modern weather research and forecasting models, which can influence the meteorological variable, and in turn the concentration of air pollutants. In this study the impact of using two traditional land use classifications, the United States Geological Survey (USGS) and the Moderate-resolution Imaging Spectroradiometer (MODIS), were evaluated. The Weather Research and Forecasting model (WRF, version 3.2.1) was run for the period 18 - 22 August, 2014 (dry season) at a grid spacing of 3 km centered on the city of Manaus. The comparison between simulated and ground-based observed data revealed significant differences in the meteorological fields, for instance, the temperature. Compared to USGS, MODIS classification showed better skill in representing observed temperature for urban areas of Manaus, while the two files showed similar results for nearby areas. The analysis of the files suggests that the better quality of the simulations favorable to the MODIS file is straightly related to its better representation of urban class of land use, which is observed to be not adequately represented by USGS.

Abstract:

Sugar cane bagasse is one of the largest fuels used for electricity generation in Brazil and its usage has continuously increased to supply the energy demand. This paper presents emission inventory based on power plants burning sugar cane bagasse. The inventory involves the spatial distribution and the estimated flows for the following major pollutants: nitrogen oxides (NOx), particulate material (PM), carbon dioxide (CO2) and total organic carbon (TOC). A total of 384 power plants were inventoried, representing a generated power of 9.9 GW, about 26% of the energy produced by thermal power plants sector. The plants are concentrated in two main poles: one of them in S?o Paulo State and nearby areas and the other one in coast of Brazilian Northeast. The limits proposed by the AP-42 Regulations of the US Environmental Protection Agency (USEPA) for the emission factors were applied. Additional emission factors identified in the scientific literature were also included in the analysis in order to assess the uncertainties associated to the estimative. The estimated emissions showed values in the range 16.0 - 20.5 Gg?year?1 for NOx, 18.0 - 267.0 Gg?year?1 for MP and 20.5 - 26.7 Tg?year?1 for CO2. The contribution of TOC showed a minor contribution around 10 - 20 Mg?year?1. PM showed to be the most representative pollutant emitted by the thermal plants burning sugar cane bagasse, but with a large range of uncertainty. There is a high level of uncertainty associated to the preparation of cane as well as the use of collectors to control particulate emissions. The adequate control over all stages could reduce the bagasse ash content in 90% or more.
