Fixa o esquelética externa em c es: avalia o clínica e microbiológica
Carneiro L.P.,Rezende C.M.F.,Silva C.A.,Laranjeira M.G.
Arquivo Brasileiro de Medicina Veterinária e Zootecnia , 2001,
Abstract: Eleven dogs, of both sexes, average weight of 12kg, with ages ranging from two to five years were used with the objective of evaluating two treatments of skin wounds produced after percutaneous bone transfixation of the tibia. In six animals, cotton swabs embedded in 0.2% iodine-alcohol were used to clean the areas of pin perforations. In five dogs, a 0.9% sodium chloride solution, under approximate 30 psi pulse pressure, was used. In both cases, and treatments were carried out every three to four days, during four weeks. Clinical specimens were collected under anaerobic conditions, immediately before the treatments, and on days 3, 7, 14 and 28 after surgery. Samples were cultured in specific media in order to allow isolation of aerobic and anaerobic bacteria and yeast. Dogs treated with sodium chloride solution showed little purulent exudation, while dogs treated with iodine-alcohol presented dry skin wounds with minimum blood-serous to serous exudation. The microbiological evaluation revealed predominance of Staphylococcus spp, but no differences were observed between the two treatments. The results allowed to conclude that both methods are efficient for post-surgical treatments of bone percutaneous transfixation in dogs.
Effect of Growth Retardants on Floral Biology, Fruit Set and Fruit Quality of Cape Gooseberry (Physalis peruviana L.)
L.P. Yadava
American Journal of Plant Physiology , 2012,
Abstract: Various doses of paclobutrazol (12.5, 25, 50 and 100 ppm) and ethephon (100, 200, 400 and 800 ppm) on flowering, fruit characters and quality of cape gooseberry (Physalis peruviana L.) were observed. Results indicated that ethephon 800 ppm delayed flowering but prolonged duration of fruit set and early ripening by 30.25, 2.5 and 10.13 days, respectively over control. 400 ppm of ethephon was more effective than 800 ppm in respect of fruit weight and quality constituents. In the same trend by 17.5, 2.37 and 5.85 days delay in flowering, prolonged duration of fruit set and early ripening, respectively were recorded with paclobutrazol 100 ppm. However, ethephon 400 ppm and paclobutrazol 50 ppm significantly influenced the fruit set, growth rate, cumulative growth, volume, density and TSS/acidity ratio of the fruit as compared to control and other concentrations of the retardants.
Spatial filter with multiple extracted poles
L.P. Mospan
Journal of Nano- and Electronic Physics , 2009,
Abstract: We present the numerical simulation results of the scattering of a plane linearly polarized wave at a multi-aperture frequency-selective surface and two design examples for a spatial band-pass filter with multiple extracted poles. Filters are formed by three consecutively placed perforated screens. Shown, that the screens, elementary cell of which contains a number of different rectangular apertures, provide the appearance of extracted poles on the frequency response of the filter.
First Principle Study on the Electric Structure of β-FeSi2 with Native Point Defects  [PDF]
L.P. Peng, A.L. He
Modeling and Numerical Simulation of Material Science (MNSMS) , 2013, DOI: 10.4236/mnsms.2013.31B004
Abstract: The projector-augmented plane wave potentials method under the density functional theory (DFT ) was used to calcu-late the electronic structure of perfect and native point defective β-FeSi2 crystal. The calculated band structure shows that the band gap of perfect crystal is about 0.74eV, which is a little smaller than the experimental of about 0.9eV. The density of states results predicts that β-FeSi2 with Fe vacancies behaves n-type, and that with Si vacancies will shows p-type, which is in accordant with the experimental results.
Corrosion Behaviour of Modified HVOF Sprayed WC Based Cermet Coatings on Stainless Steel  [PDF]
L.P. Ward, B. Hinton, D. Gerrard, K. Short
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.1011076
Abstract: WC based cermet coatings have been considered as alternative replacements to the more traditional hard chrome plating for improved surface properties of aircraft landing gear. While these coatings are used in engineering applications requiring superior hardness and improved wear resistance, little is known about the corrosion resistance. In this study, three WC based composite coatings were deposited onto ferritic stainless steel substrates using high velocity oxy fuel (HVOF) technology. Salt spray testing and potentiodynamic scanning studies in a saline environment were conducted on the coatings. Characterisation of the coating structure, composition and morphology, was carried out, prior to and after corrosion testing, using optical microscopy, scanning electron microscopy and EDX elemental analysis. The results showed that poor corrosion performance was exhibited by all three coatings. This was attributed to the high levels of porosity and the presence of micro-cracks within the coatings, resulting in attack of the substrate directly by the saline environment and possible galvanic coupling effects between the substrate and the coating. Dissolution and / or erosion of specific phases within the coating, resulting in the formation of micro-channels and increased number / size of voids may have accelerated corrosion of the system.

Síntese das hemoglobinas A2, S e C nos três primeiros meses após o nascimento
Nascimento, Maria L.P.;
Revista Brasileira de Hematologia e Hemoterapia , 2001, DOI: 10.1590/S1516-84842001000200007
Abstract: a prospective study of a2, s and c hemoglobins was made in 70 heterozygous infant cases. our results suggest, after a comparison of published studies of adults, that the normal adult levels of hb a2, hb s and hb c have been reached by the age of three months and not 6 months to one year as previously thought.

Abstract: Rivers flowing into the Kruger National Park were monitored for pesticide residues. Sampling sites were located on the Levubu, Letaba, Olifants, Sabie and Crocodile Rivers. Altogether 657 samples were analysed over two years and in only 11 or two per cent were pesticide residues found. Endosulfan was found in seven samples at concentrations ranging from 100 to 6 300 ng/dm3. Dieldrin was found in two samples at concentrations of 1 700 and 2 900 ng/dm3, while DDT was found in the other two samples at concentrations of 100 and 500 ng/dm3. In 85 samples or 13 unknown chlorinated compounds were found, possibly industrial pollutants. The results of this survey indicated that pesticides in rivers do not pose a serious threat to wildlife in the Kruger National Park.
