Operations at former weapons processing facilities in the U. S. have resulted in a large volume of radionuclidecontaminated soils and residues. In an effort to improve remediation strategies and meet environmental regulations, radionuclide-bearing particles in contaminant soils from Fernald in Ohio and the Rocky Flats Plant (RFP) in Colorado have been characterized by electron microscopy. The object of these studies was to determine the form of the contaminant radionuclide, so that it properties could be established [1]. Physical separation and radiochemical analysis determined that uranium contamination at Fernald was not present exclusively in any one size/density fraction [2]. The uranium-contamination resulted from aqueous and solid product spills, air-borne dust particles, and from the operation of an incinerator on site. At RFP the contamination was from the incineration of Pu-bearing materials. Further analysis by x-ray absorption spectroscopy indicated that the majority of the uranium was in the 6+ oxidation state [3].

: Matches of mature microRNAs (m-miRs) in human 3’utr can be traced to mutations producing fragments of original m-miR sequences without physical separation. (The by far fewer m-miR matches in 5’utr and cds follow similar patterns.) The sense and antisense m-miR fragments in 3’utr occur at quite similar levels. The fragmentation occurs at gene level by mutation within one of the paired m-miRs, which upon transcription results in increased interactive capability for both former pre-micro (pre-mir) RNA stem partners. The non-mutated stem partner can persist in 3’utr sequences, as is apparent from significant presence of miR-619-5p and miR-5096 and some conservation of 20 other simian-specific m-miR sequences. However, most of m-mir sequences in 3’utr are extensively fragmented, with low preservation of long matches. In flanks of individual m-miR embeds the mutated pre-mir positions are to a degree defined specifically. The m-mir matches of various sizes in 3’utr apparently reflect accumulation, on a phylogenetic time scale, of in-sequence point mutations. Across human 3’utr this fragmentation is significantly less for evolutionarily recent human m-miRs that originate in simians compared to human m-miRs first appearing in lower primates, and especially to human m-miRs introduced in non-primates.

Extraction of hydrogen from hydrocarbons is a logical intermediate-term solution for the escalating worldwide demand for hydrogen. This work explores the possibility of using a single membrane to accomplish both the catalytic dehydrogenation and physical separation of hydrogen gas as a possible way to improve the efficiency of hydrogen production from hydrocarbon sources. The present analysis shows that regions of pressure/temperature space exist for which the overall process is thermodynamically spontaneous (ΔG < 0). Each step in the process is based on known physics. The rate of hydrogen production is likely to be controlled by the barrier to hydrogen abstraction, with the density of H-binding sites also playing a role. A critical materials issue will be the strength of the oxide/metal interface.

This study presents a methodology for evaluating a set of crash-prone sidewalk and crosswalk locations in an urban area with respect to their existing walkability condition and recommending improvement needs. Initially, a set of 15 sidewalk specific and 10 crosswalk specific attributes relevant to India were identified from the literature. Subsequently, the analytical hierarchy process was used to estimate relative weights associated with the attributes from the perspective of relevant experts. A weighted sum method was then used to formulate a Sidewalk Condition Index (SCI) and Crosswalk Condition Index (CCI) for evaluating the condition of the existing pedestrian sidewalks and crosswalk infrastructures. Ten locations across Hyderabad with the highest pedestrian fatalities during the last three calendar years were selected as study locations. The location specific SCI and CCI estimates were used to prioritize the locations with regard to their existing condition and infrastructural requirements. Results indicated that sidewalk attributes such as sidewalk lighting, cleanliness, physical separation of traffic, and traffic speed, and crosswalk attributes such as conflicts with crossing traffic, crosswalk illumination, and intersection control, influenced safety and walkability significantly. Measures such as the provision of exclusive right-of-way for pedestrians, maintaining the sidewalk quality, enforcing no jaywalking, re-design of signal timing with pedestrian phase, and provision of zebra crossings and refuge islands, would improve walkability at pedestrian crash-prone locations across Hyderabad. This proposed methodology and the research findings could act as a critical tool to improve the overall safety and walkability of sidewalks and crosswalks in Indian cities.

Divorce Consequences

An extensive body of research exists on the consequences of divorce for children. The conclusions of this research are captured by the concept of resilience, children's ability to "bounce back" in the face of stress. Most children from divorced families cannot be distinguished from children from married families on objective measures of psychological functioning, including assessments of conduct, depression, anxiety, and school performance. Nevertheless, it is clear that divorce often creates many dramatic stressors for children, including involvement in their parents' conflicts, decreased contact with one parent, strained relationships with the other parent, and economic problems. Coping with these substantial changes can tax children's emotional resources and may leave them with lingering feelings of hurt, resentment, and longing for a parental reconciliation. The concept of resilience highlights both children's ability to cope with change and some of the painful consequences of coping with unwanted changes in family life. Definition Despite its familiarity, several considerations should be noted about the definition of divorce. First, divorce is a developmental process that unfolds over time. Changes in family life typically begin long before the physical separation and continue long after the legal divorce. Second, because divorce reaches into many areas of people's lives, theorists often talk about the "legal divorce," the "emotional divorce," the "emotional divorce," the "economic divorce," and the "social divorce."
