Physical Properties and Heat Transfer of Tectona grandis L.f. Wood

引用

Journal of Environmental Science and Engineering(B) 2012年第12期1卷 1303-1310页

作者： Joao Vicente de Figueiredo Latorraca Gilmar Correia Silva luiz Guilherme Souza lima department of Forest Products Forest Institute Federal Rural University of Rio de Janeiro BrazilSeropedica 23890-000 department of Plant Science and Zootechny State University of Southwest BahiaBrazil Vit6ria da Conquista 45083-900

Tectona grandis L.f. （teak） is native to the Indian subcontinent and southeast Asia, and today is grown in almost every tropical region, for the physical and mechanical properties of its wood. Also, important qualitative aspects render it one of the most expensive wood species in the world. This work presents a study about the physical properties and heat transfer of T. grandis wood from plantations in ***, Mato Grosso, Brazil. Six trees planted at three different intervals were used--two from each planting density--selected at random and with good phytosanitary characteristics, as well as having representative diameters and heights. The following properties were determined： basic and apparent densities, volume contraction, heat transfer and fiber saturation point. The basic and apparent mean general density of the samples was 0.48 g/cm3 and 0.55 g/cm3, respectively. The mean volume contraction of the teak wood was 8.57%. With decreased levels of wood humidity, loss of volume and planting effects were not significant at 5% probability. Mean heat transfer was 7.3 h/cm and the wood fiber saturation point was 17.25%, below the range found in literature, and there was no influence of the planting density on this property. According to the results, it was concluded that planting density significantly influenced the base density of the wood; the same effect does not occur for the other physical properties, and with respect to heat transfer, the wood was considered difficult to dry.

Promoter hypermethylation of CDH1, FHIT, MTAP and PLAGL1 in gastric adenocarcinoma in individuals from Northern Brazil

AIM：To evaluate the methylation status of CDH1, FHIT, MTAP and PLAGL1 promoters and the association of these findings with clinico-pathological characteristics.METHODS： Methylation-specific PCR （MSP） assay was performed in 13 nonneoplastic gastric adenocarcinorna, 30 intestinal-type gastric adenocarcinorna and 35 diffuse-type gastric adenocarcinorna samples from individuals in Northern Brazil. Statistical analyses were performed using the chi-square or Fisher＇s exact test to assess associations between rnethylation status and clinico-pathological characteristics.RESULTS： Hypermethylation frequencies of CDH1, FHIT, MTAPand PLAGL1 promoter were 98.7%, 53.9%, 23.1% and 29.5%, respectively. Hyperrnethylation of three or four genes revealed a significant association with diffuse-type gastric cancer compared with nonneoplastic cancer. A higher hyperrnethylation frequency was significantly associated with H pylori infection in gastric cancers, especially with diffuse-type. Cancer samples without lymph node metastasis showed a higher FHIT hypermethylation frequency. MTAP hypermethylation was associated with H pylori in gastric cancer samples, as well as with diffuse-type compared with intestinal-type. In diffuse-type, MTAP hypermethylation was associated with female gender.CONCLUSION： Our findings show differential gene methylation in tumoral tissue, which allows us to conclude that hypermethylation is associated with gastric carcinogenesis. MTAP promoter hypermethylation can be characterized as a marker of diffuse-type gastric cancer, especially in women and may help in diagnosis, prognosis and therapies. The H pylori infectious agent was present in 44.9% of the samples. This infection may be correlated with the carcinogenic process through the gene promoter hypermethylation, especially the MTAP promoter in diffuse-type. A higher H pylori infection in diffuse-type may be due to greater genetic predisposition.

Evaluation between Two Brazilian Railway Tracks

引用

Journal of Civil Engineering and Architecture 2011年第9期5卷 772-778页

作者： Cassio Eduardo lima de Paiva Creso de Franco Peixoto luiz Femando de Melo Correia Paulo RobertoAguiar Geotechnical and Transportation department UNICAMP State University of Campinas Brazil Erelys Consulting and Assessment Ltd. Brazil

Most of Brazilian railways were built more than 100 years ago. Some of them were submitted to rebuilding processes while others were just overloaded by additional layers of ballast. Nowadays, Brazil is going through a new railway transport impulse in relation to the increase of load, despite of the necessary supply capacity. For this reason, there were developed evaluations from some Brazilian railways in order to determine their operational conditions. This work shows a comparative analysis of results from two parts of studied old railway, aiming to determine minimum features to enable them to accept higher load axis. One of these studied old railway parts did not have a sub-ballast layer in contrast to the other one. The strains and stresses of these old railway track parts were generated by the same locomotive.
