The hydrologic changes and the impact of these changes constitute a fundamental global-warmingrelated concern. Faced with threats to human life and natural ecosystems, such as droughts, floods, and soil erosion, water resource planners must increasingly make future risk assessments. Though hydrological predictions associated with the global climate change are already being performed, mainly through the use of GCMs, coarse spatial resolutions and uncertain physical processes limit the representation of terrestrial water/energy interactions and the variability in such systems as the Asian monsoon. Despite numerous studies, the regional responses of hydrologic changes resulting from climate change remains inconclusive. In this paper, an attempt at dynamical downsealing of future hydrologic projection under global climate change in Asia is addressed. The authors conducted present and future Asian regional climate simulations which were nested in the results of Atmospheric General Circulation Model （AGCM） experiments. The regional climate model could capture the general simulated features of the AGCM. Also, some regional phenomena such as orographic precipitation, which did not appear in the outcome of the AGCM simulation, were successfully produced. Under global warming, the increase of water vapor associated with the warmed air temperature was projected. It was projected to bring more abundant water vapor to the southern portions of India and the Bay of Bengal, and to enhance precipitation especially over the mountainous regions, the western part of India and the southern edge of the Tibetan Plateau. As a result of the changes in the synoptic flow patterns and precipitation under global warming, the increases of annual mean precipitation and surface runoff were projected in many regions of Asia. However, both the positive and negative changes of seasonal surface runoff were projected in some regions which will increase the flood risk and cause a mismatch between water

There are many underground quarries for Oya tuff or the rhyolitic brecciate tuff, in Oya area, Utsunomiya City, Tochighi Prefecture, Japan. It is one of the most famous decorative rock materials for the buildings and the fences in Japan. The plan area of an example quarry has about 20,000m. Recently, the structural stability for these underground quarries should have been considered to redevelop the Oya area. It is one of the main vitalize sightseeing resources as underground space to be active this area again. Almost of them are abandoned quarries. Only some decades of underground quarries have been worked as Oya tuff quarry. It is difficult to decide the mechanical properties of Oya tuff because Oya tuff has the undecided characteristics. Because the main stratum structure randomly includes a lot of clay mineral grains. It is assumed that the undecided randomness follows the normal distribution. To consider the mechanical stability of an underground quarry, the authors are adopted at the linear stochastic finite element method in plane strain state. This stochastic finite element method is based on the asymptotic expansion method. It separates the empirical value into the expectation and the probability value. In this study, the authors assume that the elastic modulus, the cohesion and the internal friction angle of Oya tuff are probability values. It is assumed that the results of numerical analysis make sure the mechanical stability of the underground quarry, roughly. This study will become base information to secure the short term stability of underground quarry just after quarrying

Bassey School of Materials Science and Engineering Sichuan University of Science and Engineering Zigong China Key Laboratory of Material Corrosion and Protection of Sichuan Province Zigong China Department of Pure and Applied Chemistry University of Calabar Calabar Nigeria

Soil moisture collected from three locations, namely University of Calabar (UNICAL), Calabar municipal solid waste dumpsite (MSWD) and a mechanic workshop (MW) all within Calabar metropolis, Nigeria, were analyzed quarterly in a one year study at different depths (0.5 m and 1 m) for some physicochemical parameters. UV-visible spectrophotometer, titration and atomic absorption spectrophotometer (AAS) were the employed analytical techniques. With the exception of chloride, all other parameters showed higher values with depth. Higher values for the analyzed parameters were generally reported for MSWD and this was largely the result of the presence of a variety of contaminants in this location. Microbial analysis of soil samples from the locations revealed the presence of SRB in MW, which could have possibly influenced the soil moisture chemistry of the location. Corrosion rate was calculated from weight loss measurements and the quarterly results were all for follow the trend: UNICAL < MW < MSWD. At the end of the 4th quarter, the corrosion rates at 0.5 m depth were 0.0057, 0.0070, and 0.0101 mm/hour for UNICAL, MW, and MSWD, respectively, while their corresponding values at 1 m depth were 0.0087, 0.0114, and 0.0128 μm/hour. The values were shown to increase with depth. R-mode factor analysis identified some important factors which could have been responsible for the variation in the chemistry of the soil moisture.

Background: Giant cell tumor of the bone (GCTB) occurs most often in younger individuals aged between 20 and 40 years. However, it also occurs in a small proportion of elderly people. Therefore, it is necessary to determine the clinical characteristics of GCTB in elderly people, as only few reports have completely examined the characteristics of GCTB in elderly patients. Methods: This retrospective study enrolled 69 patients with benign GCTB. Patients’ information on age, sex, anatomical location and size, Campanacci grade, pathological fracture, treatment for primary tumors, local and distant relapse, and outcome was collected. We compared these clinical courses between the younger and older groups. We divided the age groups into three subgroups: ≤54 years and ≥55 years, ≤59 years and ≥60 years, and ≤64 years and ≥65 years. We compared the two groups in each subgroup. In addition, we examined factors affecting local recurrence and distant metastasis. Results: Tumor size was significantly larger in the older group between the two subgroups of 55 and 60 years. Kaplan-Meier curves for local recurrence-free survival and distant metastasis-free survival between the two subgroups of 65 years showed significant differences (p = 0.0183 and p

Consistent with the growing search for the discovery of cheap and environmentally friendly corrosion inhibitor materials for industrial applications, this work presents the potency of the ethanol extract of Phellodendron chinese Schneid as an eco-friendly corrosion inhibitor for carbon steel in HCl solution. The corrosion behavior of carbon steel was evaluated using electrochemical impedance spectroscopy measurements, potentiodynamic polarization measurements, gravimetric experiments and surface analytical techniques. Results from electrochemical and gravimetric experiments showed that the corrosion protection efficiency of the inhibitor increased with extract concentration but the strength of protection decreased as the solution temperature was increased. Thermodynamics of adsorption and kinetics of electrochemical reactions were used to discuss the inhibition mechanism. The presence of adsorbed constituents was revealed by electrochemical and spectroscopic measurements while scanning electron microscopy confirmed the existence of the adsorbed layer on the surface of carbon steel coupons.
