Solos sob vegeta??o de restinga na Ilha do Cardoso (SP): I - Caracteriza??o e classifica??o
Gomes, Felipe Haenel;Vidal-Torrado, Pablo;Macías, Felipe;Gherardi, Bruno;Perez, Xosé Luiz Otero;
Revista Brasileira de Ciência do Solo , 2007, DOI: 10.1590/S0100-06832007000600033
Abstract: restinga is a typical vegetation on quartzitic, sandy, nutrient-poor parent materials along the brazilian coast. soils under restinga vegetation on the ilha do cardoso (sp) were studied to understand their genesis and to improve the brazilian soil classification system (sibcs). thus, a physical, chemical and detailed morphological characterization was carried out. the results evidenced aquic, sandy, very acid soils with variable organic matter content, in which podzolization is the main pedogenic process. sulphidric materials also occur due to the influence of different underlying iron sulphide-bearing materials, not related to podzolization. the main factors that affect soil distribution are the age of parent material and the microtopography, which reflects the influence of the water table. the studied spodosols are holocenic and podzolization depends on aquic conditions, which is determinant for the genesis of the spodic horizon. the sibcs classification of the spodosol order at the 2 nd category level (suborder) is misleading, mainly in relation to the accumulation of iron in the spodic horizon. chemical criteria in the suborder definition of the sibcs should be defined and the "thionic" qualifier at the 4 th category level should be included due to the possibility of formation of acid sulphate soils in artificially drained areas.

Abstract: this work was carried out to study respiration and ethylene production behavior of red strawberry-guavas and to assess the preservation of fruit postharvest quality by treatment with different doses of 1-methylcyclopropene (1-mcp) and fruit packaging in plastic films, under refrigeration. red strawberry-guavas exhibit a climacteric behavior of respiration and ethylene production. fruits treated with increasing doses of 1-mcp (0, 100, 300, 600, and 1,200 nl l-1) and stored at 10±1c/90±5% rh for 10 days had a substantial delay in ripening, with a better retention of texture and inhibition in the change of the color of the skin. fruits packed in different plastic films (low density polyethylene, vinyl polychloride, and nylon based films) showed, in general terms, a better retention of texture and green color of the skin, and lower mass loss during cold storage (at 5c and 10c). the results showed that red strawberry-guavas are highly perishable, as a result of their high respiration and ethylene production rates. this requires immediate storage under refrigeration, and the treatment with 1-mcp or fruit packing in plastic films to preserve their postharvest quality.

Abstract: the genetic variability of quercus suber l. has been verified and examined by several authors, mainly through the evaluation of the restriction fragment length polymorphisms (rflps), isoenzymatic polymorphisms, suberin and waxes compositions, and, also, suberin?s triglyceride contents in order its potential use in the improvement of the cork quality could be established. in this context, total dna extracts obtained from two portuguese cork oaks have been amplified by the polymerase chain reaction (pcr), using a specific, well-conserved molecular marker that occurs in the proximal promoter region of the plant histone h3 genes (type i element, ccacgtcaccgatccgcg). a comparison of the electrophoretic profiles of the pcr products has allowed the detection of genetic variabilities between the studied trees whose potential implications may be associated with the cork quality. these results, that are here reported for the first time as far as known, although preliminary suggest that, at least, the molecular marker above mentioned may be used for screening, and characterization of the quercus suber l. genetic variabilities. this is the objective of several studies that are actually in course by this team.

Copper passivation procedure for water-filled copper cells for applications in metrology
Bruno Buée,Alexandre Vergé,Vladimir Vidal,Eric Georgin,Fernando Sparasci
Physics , 2012,
Abstract: In the framework of the European research project MeteoMet, the LNE-CNAM and the LNE-CETIAT are developing novel copper cells for the determination of the water vapour pressure equation and the measurement of the triple point of water temperature at the highest degree of accuracy. The Water Vapour Pressure Equation (WVPE) is the basic formula for the calculation of the vapour pressure and other humidity related quantities. Improvement in the uncertainty of the water vapour formulation in the temperature range between -80^{\cdot}C (and possibly down to -90^{\cdot}C) and +100^{\cdot}C is needed for the improvement of primary standards in the field of hygrometry. The Triple Point of Water (TPW, temperature 273,16 K) plays a key role in thermometry, because of its threefold function. On one side, it defines the temperature unit, the kelvin. On the other side, it is the reference point in Standard Platinum Resistance Thermometer (SPRT) calibrations, according to the International Temperature Scale of 1990 (ITS-90). Finally, it is the connection point between the current definition of the kelvin and the future one, based on the Boltzmann constant. Copper cells for WVPE and TPW allow highly accurate temperature control, fast thermal response time and excellent thermal uniformity, because of the elevated copper thermal conductivity. Thus, they can be an outstanding tool for reducing measurement uncertainty. Nevertheless, accurate filling techniques and procedures are necessary, to minimize water contamination and get stable, accurate and reproducible results. This report describes the filling system and the copper passivation and cleaning procedure, as well as the method for filling copper cells with high-purity water.

Abstract:

The aim of this study was to identify three-dimensional microstructural changes of trabecular bone with age and gender, using micro-computed tomography. Human trabecular bone from two disease groups, osteoporosis and osteoarthritis was analyzed. A prior analysis of the effects of some procedure variables on the micro-CT results was performed. Preliminary micro-CT scans were performed with three voxel resolutions and two acquisition conditions. On the reconstruction step, the image segmentation was performed with three different threshold values. Samples were collected from patients, with coxarthrosis (osteoarthritis) or fragility fracture (osteoporosis). The specimens of the coxarthrosis group include twenty females and fifteen males, while the fragility fracture group was composed by twenty three females and seven males. The mean age of the population was 69 ± 11 (females) and 67 ± 10 years (males), in the coxarthrosis group, while in the fragility fracture group was 81 ± 6 (females) and 78 ± 6 (males) years. The 30 μm voxel size provided lower percentage difference for the microarchitecture parameters. Acquisition conditions with 160 μA and 60 kV permit the evaluation of all the volume’s sample, with low average values of the coefficients of variation of the microstructural parameters. No statistically significant differences were found between the two diseases groups, neither between genders. However, with aging, there is a decrease of bone volume fraction, trabecular number and fractal dimension, and an increase of structural model index and trabecular separation, for both disease groups and genders. The parameters bone specific surface, trabecular thickness and degree of anisotropy have different behaviors with age, depending on the type of disease. While in coxarthrosis patients, trabecular thickness increases with age, in the fragility fracture group, there is a decrease of trabecular thickness with increasing age. Our findings indicate that disease, age and gender do not provide significant differences in trabecular microstructure. With aging, some parameters exhibit different trends which are possibly related to different mechanisms for

Abstract: objective: virulent strains of the mycobacterium tuberculosis complex, under certain appropriate conditions, grow as characteristic ropes, bundles or serpentine cords known as cord factor or growth in cords. the objective of the present study was to evaluate cord factor detection as a method of achieving presumptive identification of the m. tuberculosis complex, comparing it to conventional typing tests. methods: a total of 743 strains were analyzed from january of 2002 to december of 2005 in the mycobacteria sector of the adolfo lutz institute, located in the city of santos, brazil. samples were obtained from clinical specimens collected from patients with respiratory symptoms treated at basic health clinics in the greater metropolitan area of santos. ziehl-neelsen-stained smears were prepared, 301 (40.5%) in mb/bact broth and 442 (59.5%) on solid media, either lowenstein-jensen or ogawa-kudoh. results: the sensitivity, specificity, positive predictive value and negative predictive value obtained during the performance comparison of the two methods (cord factor detection and conventional typing) using both isolation media were, respectively, 98.5, 88, 97 and 93%. the method was more sensitive on solid medium (100%), and the difference in sensitivity between the two media types was only 2.7%. conclusions: taking into consideration the results obtained, we conclude that, in laboratories with a high incidence of m. tuberculosis complex isolation and limited economic resources, cord factor detection is a fast and valid criterion for identifying these mycobacteria using liquid or solid medium. it also enables subsequent conclusive identification tests, as well as additional sensitivity tests when necessary.

Open Journal of Accounting (OJAcct) , 2014, DOI: 10.4236/ojacct.2014.31005
Abstract: Many reforms have been undertaken in recent years; indeed, scholars have concentrated their attention on ac-counting techniques, financial management, and the potential for adding tools to support managerial reform agendas [1-3]. This paper extends prior research by focusing on the manner of diffusion ongoing reform process, through the adoption of the new version of Financial Management Reform process model [3]. The objective of this research is to investigate how a new accounting system has been introduced in the public sector in a processual and outcome-oriented analysis [4]. The study setting for this research is the Italian government, specifically the intermediate or regional level government, Campania Region, where a trial period is underway. The objective is to discover what obstacles and difficulties might exist when implementing a harmonized accounting and budgeting system while moving toward an accrual accounting system. The study reveals the main paradox in the implementation of the reform. This kind of study could add fresh knowledge to the literature and highlight common problems encountered when implementing accounting reforms. Additionally it could help set a standard to assist public entities in developing and implementing accounting guidelines.
