Eu3+-activated oxide components appear as a kind of rare-earth red phosphors that can be used for warm white light-emitting diode (LEDs). At present, it is still challenge to synthesize oxide-component with high photoluminescence quantum yields compared those nitride and fluoride phosphors. Herein, we propose Gd4.67Si3O13 silicate phosphor by the convenient high-temperature solid reaction method. These designed effectively excited either 394 nm near-ultraviolet light or 465 blue then emit at...
Landslide susceptibility depends on various causal factors such as geology, land use/land cover (LULC), slope, and elevation. Unlike other that are relatively stable over time, LULC is a dynamic factor associated with human activities. This study evaluates the impact of change landslide in Rangamati municipality district, Bangladesh, based three scenarios—the existing (2018) LULC, proposed (proposed 2010, but not yet implemented), simulated 2028—using artificial neural network (ANN)-based...
The accuracy and quality of the landslide susceptibility map depend on available locations sampling strategy for absence data (non-landslide locations). In this study, we propose an objective method to determine critical value based Mahalanobis distances (MD). We demonstrate mapping three subdistricts (Upazilas) Rangamati district, Bangladesh, compare results with produced slope-based method. Using 15 causal factors, including slope, aspect, plan curvature, first 23.69 Chi-square...
The Qinghai-Tibetan Plateau plays an important role in global climate and environmental change holds the largest lake area China, with a total surface of 36,900 km2. expansion shrinkage these lakes are critical to water cycle ecological systems across plateau. In this paper, areas major within plateau were extracted based on topographic map from 1970, Landsat MSS, TM ETM+ satellite images 1970s 2008. Then, multivariate correlation analysis was conducted examine relationship between changes...
Most glaciers in the Himalayas and Tibetan Plateau are retreating, glacier melt has been emphasized as dominant driver for recent lake expansions on Plateau. By investigating detailed changes extents levels across from Landsat/ICESat data, we found a pattern of dramatic 1970 to 2010 (especially after 2000) with southwest-northeast transition shrinking, stable, rapidly expanding. This is distinct contrast spatial characteristics retreat, suggesting limited influence dynamics. The plateau-wide...
Assessing long-term hydrological impacts of land use/land cover (LULC) change is critical importance for use planning and water resource management. The Little River Watershed, Tennessee, an important watershed supporting drinking recreational activities within around the Great Smoky Mountains National Park in Unites States. However, potential LULC change, especially urbanization recent decades, are not quantified. This paper assessed on streamflow non-point source pollution using Soil Water...
Landslide susceptibility mapping is of critical importance to identify landslide-prone areas reduce future landslides, causalities, and infrastructural damages. This paper presents landslide maps at a regional scale for the Chittagong Hilly Areas (CHA), Bangladesh. The frequency ratio (FR) was integrated with analytical hierarchy process (AHP) (FR_AHP) logistic regression (LR) (FR_LR). A inventory 730 locations 13 predisposing factors including elevation, slope, aspect, plan curvature,...
An anti-thermal quenching strategy is proposed to develop GdNbO 4 :Pr 3+ red phosphor, which a promising candidate for the high-performance optical temperature sensing with increasing emission intensity during heating process.
The untargeted metabolomics of Newhall navel oranges from three areas in China—Ganzhou, Fengjie, and Zigui—with geographical indication (GI) was measured using LC-MS/MS. Orthogonal partial least squares discriminant analysis performed for sample classification important metabolite identification. This approach identified the best markers origin able to discriminate Ganzhou, Zigui orange samples. For peeled samples, 2-isopropylmalic acid, succinic citric L-aspartic L-glutamic γ-semialdehyde,...
Accurately documenting urban growth and evaluating its hydrological impact are of great interest for planning water/land resource management. St. Charles County, a suburb Louis, Missouri, has undergone significant expansion in recent decades. Rapid sprawl the Dardenne Creek watershed within county had profound influence on surface runoff. We examined patterns land use/land cover (LULC) change this using Landsat TM/ETM+ imagery 1982, 1987, 1991, 1999, 2003. Calibrated with observed data 2003,...
This paper presents a preliminary study on lake-level fluctuations since the Last Glaciation in Selin Co (lake), Central Tibet, by dating four groups of beach ridges using optically stimulated luminescence (OSL). The highest/oldest ridge group (>100 m higher than current lake level) is dated back to 67.9 ± 2.4 ka BP, corresponding early stage (marine isotope (MIS) 4). date further supports that no plateau-scale ice sheet covered Tibetan Plateau during Glaciation. other three produce OSL ages...
