Large lateral thoracic defect by chondrosarcoma resection chest wall reconstruction using myocutaneous latissimus dorsal flap without parietal rigid repair
Guerrissi Jorge,Brunini Jose
Indian Journal of Plastic Surgery , 2005,
Abstract: A case of a 66 year-old women, with a large chondrosarcoma arising from right lateral chest wall is presented. Parietal pleura, 3rd, 4th, 5th and 6th ribs (lateral arch), underlying muscle, subcutaneous tissues and the right breast were also involved by the tumor. Surgical resection was planned including skin, right breast, 3rd, 4th, 5th and 6th lateral rib arches and parietal pleura; a wide defect was created with exposure of lung. Reconstruction was planned by means of an extensive myocutaneous dorsal flap pedicled on right thoracodorsal vessels; alloplastic mesh for parietal chest wall reconstruction was not used. Two years postoperative results showed no local recurrence and excellent aesthetic and functional results were evident; respiratory function remained unaltered. The progressive rigidity reached by the reconstructed lateral chest wall, allowed us to conclude that the use of myocutaneous flap is enough to avoid paradoxical respiratory movements and any type of alloplastic mesh is unnecessary.

Abstract: agricultural drought has always brought serious problems related to food production in the state of s?o paulo, brazil. the scope of this study was to adapt the methodology of the standardized precipitation index (spi) to the historical values of actual evapotranspiration series fitted to the beta distribution, to quantify agricultural drought in the state of s?o paulo. the new index is named standardized actual evapotranspiration index (iper). the results indicates that such new index, iper, is vey useful to the "near real time monitoring" of the agricultural drought in a ten day period. it was observed that the range of this new index is directly related to the numbers of standard deviation for which a given value of actual evapotranspiration is below of its expected value, indicating the intensity or severity of the agricultural drought.

Abstract: a drought event for the palmer drought severity index (pdsi) is defined as a period of time during which the actual moisture supply at a given place rather consistently falls short of the climate appropriate moisture supply. based on historical precipitations series, which were fitted to the gamma distribution, the standardized precipitation index (spi) recognizes the importance of the time scale in the analysis of the water availability and water management. based on parameters of the water balance of thirteen regions, the scope of this study was to test and adapt the pdsi and the spi models to the climate conditions of the state of s?o paulo. the tests were done caring out the index values and the deviations between the estimated water balance parameters in a period and the climate expected value of this parameters for the period that is been considerate. the spi values were tested in several times scales. the main focus of the pdsi adjustment (pdsi adap) was the adaptation of the k factor and the palmer's index final equation. the analysis allows to conclude that such study resulted in a useful tool for the monthly "real time monitoring" of the meteorological drought conditions for the state of s?o paulo. the spi model also demonstrated to be a consistent "precipitation deficit monitoring tool" in several time scales. both indices should be used as part of a overall state government actions to drought affected regions and mitigation policy.

Revista Brasileira de Meteorologia , 2007, DOI: 10.1590/S0102-77862007000100011
Abstract: the standardized precipitation index (spi) and the palmer drought severity index, on it?s original form (pdsi) and on it?s climate conditions of the state of s?o paulo adapted model (pdsi adap) are been used by the instituto agron?mico (iac) through the ciiagro to evaluate the agricultural, the meteorological, the hydrological and the socioeconomic impacts of a drought. regarding the particular characteristics of each index, this study compares the spi, the pdsi and the pdsi adap models. this work also gives information about the correct interpretations of the results for each drought index. due it?s capability to recognizes the importance of time scales in the analysis of water availability and water use, due it?s spatial consistence and it?s simplicity interpretation the spi should be used on studies of drought risk and mitigation over different segments of the human society. the pdsi adap could be used as a "meteorological drought monitoring tool", in monthly basis, on the state of s?o paulo.
Análise da escola temporal de monitoramento das secas agrícolas e meteorológicas no estado de S?o Paulo

Revista Brasileira de Meteorologia , 2007, DOI: 10.1590/S0102-77862007000200010
Abstract: the monitoring of each type of drought has been based on index that attempt to encapsulate then on regional and temporal basis. the results of those mathematical models on drought implications are associated with choosing the correct time scale that each drought concept should be analyzed. the study was based on monthly and ten day period precipitation average and its standard deviation, and the kolmogorov-smirnov test. the paper also compared the index departures with climate water balance parameters. the importance of using the correct time scale, when meteorological drought index (pdsi adap and spi) or agricultural drought index (iper) are been used was shown. while the study of the meteorological drought implications has to be done on times scales equal or bigger than the monthly, the agricultural impacts, has to be analyzed based on parameters that are directly associated with actual evapotranspiration of the crops and, even on shorts times scales, the establishment of an expected value of those parameters, that allow the quantification of an crop water surplus deficit, could be detected.

Abstract: the scientific analysis of drought is directly associated with the meteorological characteristics of a given area. therefore, the climate characterization of that area is the first step to be pursued by a study of drought. considering agricultural drought as a deficit between the estimated actual evapotranspiration over a period and the expected value for the period under evaluation, the aim of this study was to analyze four different types of probability density function (normal, log-normal, gamma and beta). the kolmogorov-smirnov test was used to verify the tack of the etr series, in a ten-day period to the above-mentioned theoretical distributions. air temperature and precipitation data of 13 locations of the state were used to calculate the climate water balance. beta distribution has proved the best adjustment compared with the others, and is recommended as a basis for an agricultural standardized drought index.

Revista mexicana de astronomía y astrofísica , 2006,
Abstract: Para entender la variedad de sistemas planetarios extra-solares es necesario comprender mejor el proceso de formación del Sistema Solar. Por esta razón, investigamos la relación entre el origen de la oblicuidad de los planetas gigantes y el origen de sus satélites, aún de poner límites a las teorías actuales relacionadas con los procesos finales de formación de planetas. Hacemos énfasis en el sistema de Urano.
Planet Formation: Statistics of spin rates and obliquities of extrasolar planets

Abstract: We develop a simple model of planetary formation, focusing our attention on those planets with masses less than 10 Earth masses and studying particularly the primordial spin parameters of planets resulting from the accretion of planetesimals and produced by the collisions between the embryos. As initial conditions, we adopt the oligarchic growth regime of protoplanets in a disc where several embryos are allowed to form. We take different initial planetary system parameters and for each initial condition, we consider an evolution of 20 millon of years of the system. We perform simulations for 1000 different discs, and from their results we derive the statistical properties of the assembled planets. We have taken special attention to the planetary obliquities and rotation periods, such as the information obtained from the mass and semi major axis diagram, which reflects the process of planetary formation. The distribution of obliquities was found to be isotropic, which means that planets can rotate in direct or indirect sense, regardless of their mass. Our results regarding the primordial rotation periods show that they are dependent on the region where the embryo was formed and evolved. According to our results, most of the planets have rotation periods between 10 and 10000 hours and there are also a large population of planets similar to terrestrial planets in the Solar System.
