Diagnosis of the new genus Tegosecans gen. nov. is that body spindle- shaped, scapular setae ahead of rear shield margin; opisthosoma of smooth dorsal and microtuberculate ventral annuli, dorsal annuli with central longitudinal ridge ending before lateral median ridges; second dorsal annulus broader, covering the next 2 annuli, 3–4 dorsal annuli with lateral lobes. The 10 new species are Trisetacus fortunei sp. nov., Glyptacus kweilinensus sp. nov., Neoacaphyllisa phaeosticta sp. nov., Oxycenus tomentosae sp. nov., Phyllocoptacus fortuneir sp. nov., Tegosecans jinxiuensis gen. nov. ＆ sp. nov., Epitrimerus sinensis sp. nov., Phyllocoptes glaucifoliae sp. nov., Diptilomiopus pomiferae sp. nov., and Vimola laxifloris sp. nov.. All of these new species are on the undersurface of leaves and cause no apparent damage to the host plants.展开更多

The finding is very interesting when there is no ownership structure variation, so the decision to choose international involvement could not be supported. Also, the scale determination is not becoming constraint of SMEs in East Java to involve internationally, especially thought export strategy. However, several aspects are considered to control the export behavioral dimension which is research and development （R＆D） and sales, significantly. The result shows that there still are other elements except ownership type could impact internationalization strategy choices of SMEs in East Java.展开更多

T3 is known to regulate gene transcription through its nuclear receptors. We have previouslyisolated many genes which are up-regulated by T3 in theintestine of Xenopus laevis tadpoles. We have now cloneda full- length cDNA for one such gene (IU12). Sequenceanalysis shows that the IU12 cDNA encodes a plasmamembrane protein with 12 transmembrane domains andhomologous to a mammalian gene associated with cell activation and organ development. Similarly, we have foundthat IU12 is activated during intestinal remodeling whenboth cell death and proliferation take place. Furthermore,IU12 is an early T3-response gene and its expression in theintestine during T3-induced metamorphosis mimics thatduring normal development. These results argue for a roleof IU12 in the signal transduction pathways leading to intestinal metamorphosis.展开更多

The rain-induced landslide disasters have been resulting in 65 fatalities and a substantial socioeconomical loss in last December 2007. Again, in early February 2009, 6 more people died, hundreds of people temporary evacuated and tens of houses damaged due to the rain-induced landslide. Accordingly, inter-disciplinary approach for geological, geotechnical and social investigations were undertaken with the goal for improving community resilience in the landslide vulnerable villages. Landslide hazard mapping and communitybased landslide mitigation were conducted to reduce the risk of landslides. The hazard mapping was carried out based on the susceptibility assessment with respect to the conditions of slope inclination, types and engineering properties of lithology/soil as well as the types of landuse. All of those parameters were analyzed by applying weighing and scoring system which were calculated by semi qualitative approach (Analytical Hierarchical Process). It was found that the weathered andesitic-steep slope (steeper than 30o) was identified as the highest susceptible slope for rapid landslide, whilst the gentle colluvial slope with inter-stratification of tuffaceous clay-silt was found to be the susceptible slope for creeping. Finally, a programme for landslide risk reduction and control were developed with special emphasize on community-based landslide mitigation and early warning system. It should be highlighted that the social approach needs to be properly addressed in order to guarantee the effectiveness of landslide risk reduction.展开更多

In Europe, a general decline of amphibians population parallels a worldwide decline, and some of the factors which are thought to be responsible to this decline are habitat loss, introduction of exotic species, disease and decreasing water quality. Recent investigations suggest that these eutrophic conditions may be associated with frog reproduction problems. Water quality criteria settled for the different species of amphibians do not currently exist, but in the present paper, the authors report their observation about water phosphate concentrations in association with hipofertility in African clawed frogs （Xenopus laevis）. The study considered two different groups of African clawed frog showing hypofertility （22 patients） hosted in captivity. The animals were visited, and the filtration systems functionality and the water quality were checked, i.e., temperature, pH, ammonia, nitrite, nitrate, phosphates, hardness and alkalinity. In the first group, it was decided to perform ultrasound scans, parasitological tests on fecal samples, and microscopical/macroscopical examination, as well as microbiological analysis on collected oocytes. In the second group, only fecal samples were collected in order to perform parasitologiacal exams. No pathological findings were showed by veterinary tests. Water changes were carried out in both facilities and after two months, the fertility in African clawed frogs improved, evidencing the involvement of phosphates values in the onset of the problem and even more in its resolution. More studies are needed to further define this correlation.展开更多
