Sediment bodies produced during historical periods of human land use, sometimes referred to as legacy sediment, may be found in various locations within drainage basins, and potentially remobilized by hydrogeomorphic processes accompanying land use change. The amounts and locations of stored legacy sediment can be significant factors in modern drainage basin function and should be accounted for when possible. In this study, late nineteenth-century erosion and sediment storage were investigated and used to construct approximate sediment budgets for two small Blue Ridge Mountain drainage basins in North Carolina (USA). Erosion was quantified using a distributed implementation of the Universal Soil Loss Equation (USLE), and calibrated on the separate bases of soil profile truncation data and recent published rates for long-term erosion in the region. Sediment yield information was reconstructed from pond sediments trapped behind a mill dam. Alluvial sediment storage was quantified using field studies of streambank and floodplain sediment profiles and digital elevation data. Colluvial storage was calculated as a residual in the sediment budget, and further evaluated using soil profile studies of footslope deposits, and soil survey maps. The proportions of erosion accounted for by the different budget terms in the most reliable budget are: 28% sediment yield (i.e., a sediment delivery ratio of 0.28), 69% colluvial storage, and 3% alluvial storage. Blue Ridge basins with low levels of ground disturbance erode like Piedmont basins at high levels of ground disturbance, primarily due to higher slope angles. Sediment delivery ratio is high relative to those given for much larger basins in the adjacent and more frequently studied Piedmont province, and generally in accordance with published sediment delivery curves that reflect higher hydrogeomorphic connectivities within smaller basins. Low values for alluvial storage in Blue Ridge basins may be explained by high sediment transport within steep channels. Colluvial storage values have high uncertainties because of the well known problem of error accumulation in residual budget terms. Field data on colluvial deposits reported here are not sufficient to correct for this problem, and in general, the acquisition of accurate field data on historical colluviation remains an important methodological issue in historical sediment budgeting. © 2016 Elsevier B.V.

In this work, we propose a reliable microcontact printing (μCP) process for generating Patterned Supported Phospholipids Bilayer (P-SPB) confined by Poly-l-(lysine)-grafted-polyethylene(glycol) (Pll-g-PEG) molecular barriers. The efficiency of Pll-g-PEG for inhibiting the fusion process of incubated liposome was first analyzed by Quartz Micro Balance (QCM) measurements. The quality and stability of Pll-g-PEG patterns were then both verified by fluorescence microscopy and Atomic Force Microscopy (AFM) in liquid media. The micro domains of P-SPB produced were stable in liquid environment during several weeks and also during AFM imaging. This exceptional stability is a clear improvement compared to previous studies involving proteins as confinement barriers. © 2011 Elsevier B.V. Source

Timely and regular information on urban environmental quality (UEQ) is essential for urban planning. This research evaluated the ten-year UEQ changes in Indianapolis, Indiana, U.S.A, based on the synthetic indicators of physical variables extracted from remotely sensed images and socioeconomic variables derived from census data. Physical environmental variables such as land use and land cover data, land surface temperature, normalized difference vegetation index, and other transformed remote sensing variables were derived from the two Landsat images taken in 1991 and 2000. Socioeconomic variables including population density, house characteristics, income, and education level were extracted from US census 1990 and 2000 block group (BG) data. Correlation analysis and factor analysis were performed after the two groups of variables were integrated at the BG level. For each year, four factors were identified and interpreted as greenness, crowdedness, economic status, and scenic amenity. By assigning different weights to each factor, two synthetic UEQ indexes were generated. A comparison of the two synthetic indexes revealed significant changes in UEQ pattern from 1990 to 2000. © 2008 IEEE. Source

Field and archival research demonstrates that although not accurately documented in historic records, small, water-powered mills may have been common throughout the southern Blue Ridge during the nineteenth century. Investigations in the Bent Creek watershed of North Carolina indicate that, as in other physiographic regions, the impoundment of low-order streams resulted in the trapping of a portion of sediment eroded from steep slopes as settlers cleared land for agriculture and logging. Sediment remobilized as a result of subsequent dam breaching and channel incision may have added between 2–5 t km−2 y−1 to Bent Creek sediment yield values during the early twentieth century. Approximately one-half of nineteenth century pond sediment remains stored as quasi-stable, terrace-like landforms within the bottomlands of Bent Creek watershed, but the potential for this sediment to transition to sediment source remains should fluvial conditions in the watershed change in the future. ©2016, Southeastern Geographer.

Radiological exposure from nuclear power reactor accidents, transportation of nuclear waste accidents, industrial accidents, or terrorist activity may be a remote possibility, but it could happen. Nurses must be prepared to evaluate and treat pregnant women and infants who have been exposed to radiation, and to have an understanding of the health consequences of a nuclear or radiological incident. Pregnant women and infants are a special group of patients who need consideration when exposed to radiation. Initial care requires thorough assessment and decisions regarding immediate care needs. Ongoing care is based on type and extent of radiation exposure. With accurate, comprehensive information and education, nurses will be better prepared to help mitigate the effects of radiation exposure to pregnant women and infants following a radiological incident. Information about radiation, health effects of prenatal radiation exposure, assessment, patient care, and treatment of pregnant women and infants are presented. Source
