Adsorption of uranyl to SWy-1 montmorillonite was evaluated experimentally and results were modeled to identify likely surface complexation reactions responsible for removal of uranyl from solution. Uranyl was contacted with SWy-1 montmorillonite in a NaCIO4 electrolyte solution at three ionic strengths (I = 0.001, 0.01, 0.1), at pH 4 to 8.5, in a N2(g) atmosphere. At low ionic strength, adsorption decreased from 95% at pH 4 to 75% at pH 6.8. At higher ionic strength, adsorption increased with pH from initial values less than 75%; adsorption edges for all ionic strengths coalesced above a pH of 7. A site-binding model was applied that treated SWy-1 as an aggregate of fixed-charge sites and edge sites analogous to gibbsite and silica. The concentration of fixed-charge sites was estimated as the cation exchange capacity, and non-preference exchange was assumed in calculating the contribution of fixed-charge sites to total uranyl adsorption. The concentration of edge sites was estimated by image analysis of transmission electron photomicrographs. Adsorption constants for uranyl binding to gibbsite and silica were determined by fitting to experimental data, and these adsorption constants were then used to simulate SWy-1 adsorption results. The best simulations were obtained with an ionization model in which AlOH2+ was the dominant aluminol surface species throughout the experimental range in pH. The pH-dependent aqueous speciation of uranyl was an important factor determining the magnitude of uranyl adsorption. At low ionic strength and low pH, adsorption by fixed-charge sites was predominant. The decrease in adsorption with increasing pH was caused by the formation of monovalent aqueous uranyl species, which were weakly bound to fixed-charge sites. At higher ionic strengths, competition with Na+ decreased the adsorption of UO22+ to fixed-charge sites. At higher pH, the most significant adsorption reactions were the binding of UO22+ to AlOH and of (UO2)3(OH)5+ to SiOH edge sites. Near-saturation of AlOH sites by UO22+ allowed significant contributions of SiOH sites to uranyl adsorption.

OBJECTIVES/GOALS: The North Carolina Translational and Clinical Sciences Institute (NC TraCS) supports faculty and staff in carrying out clinical and translational research at UNC-Chapel Hill. To better understand customer satisfaction and impact, a survey was administered among NC TraCS users. METHODS/STUDY POPULATION: NC TraCS has 13 program areas that range from Biostatistics to Community and Stakeholder Engagement. These programs provide services to faculty, staff, students, and outside researchers in the area of clinical and translational science. A customer feedback survey was administered in Spring 2019 to anyone who had used at least one NC TraCS service between March 1st, 2017 and February 28th, 2019. A total of 856 survey invitations were sent. The survey included questions around users’ perception of the ease of access, helpfulness, outcome, and promptness of the services received using 6-point Likert scale. The survey also addressed career impact, communications, and suggestions for improvement. RESULTS/ANTICIPATED RESULTS: We received 268 responses, (31% response). Majority of respondents were satisfied with Overall Helpfulness (95%), Outcome of Service (96%), Ease of Access (93%), and Promptness of Service (90%). They also noted that their careers had at least slightly improved in the following areas: Mentorship (76%), Research Methods (75%), Skill Development (77%), Research Direction (71%) and Collaboration (80%). Furthermore, 96% responded positively to returning to TraCS. The feedback received was shared with service administrators and NC TraCS leadership to identify areas of improvement and further strengthen their services. Concerns, when present, were addressed by service directors or the overall PI’s. DISCUSSION/SIGNIFICANCE OF IMPACT: Need to communicate expectations to customers the expected turn-around time for help emerged as a clear take-away. In response, TraCS leadership is working to improve staffing and workflows for efficient service delivery including expectation management, especially among the most popular services.

We present the results of a combined experimental and theoretical study of drop coalescence in the presence of an initial temperature difference $\unicode[STIX]{x0394}T_{0}$ between a drop and a bath of the same liquid. We characterize experimentally the dependence of the residence time before coalescence on $\unicode[STIX]{x0394}T_{0}$ for silicone oils with different viscosities. Delayed coalescence arises above a critical temperature difference $\unicode[STIX]{x0394}T_{c}$ that depends on the fluid viscosity: for $\unicode[STIX]{x0394}T_{0}>\unicode[STIX]{x0394}T_{c}$, the delay time increases as $\unicode[STIX]{x0394}T_{0}^{2/3}$ for all liquids examined. This observed dependence is rationalized theoretically through consideration of the thermocapillary flows generated within the drop, the bath and the intervening air layer.

Glen’s flow law is a well-established general law for steady-state glacier ice deformation, and many laboratory tests and field measurements have been undertaken which have shown the generality of the law to be correct. In Nature, ice deformation is the response of the glacier/ice sheet to the applied self-weight stress of the ice mass (i.e. ice thickness, gravity and ice density) which produces a stress gradient within the ice column. Detailed experimental analyses of ice samples in the laboratory have until now only been undertaken using uniform stress fields in uniaxial or triaxial tests. Obviously the best method for investigating ice in the laboratory would be if stress gradients similar to those found in Nature could be replicated. In the following paper we describe the physical modelling of two (laboratory-prepared) isotropic, polycrystalline ice models (0.75 × 0.25 × 0.18 m) at enhanced gravity levels (80g) in a geotechnical beam centrifuge. Steel plate was placed on top of the ice model, replicating an overburden of approximately 36 m of ice (at 80g). Thus we were able to model the deformation of the lower 14 m of an ice mass approximately 50 m thick. Models are confined laterally by the Perspex strongbox walls, preventing lateral extension within the sample during testing. Models are unconfined on their downslope ends, rendering longitudinal stresses negligible. Deformation can therefore be treated as simple shear. Samples are instrumented with displacement markers and thermocouples. Values for A and n in the flow law derived from the experiments are reasonable and indicate the potential of this method for ice-deformation studies.

A high intake of fruit and vegetables (FV) has been associated with reduced risk of a number of chronic diseases, including CVD. The aim of this review is to describe the potential use of biomarkers to assess FV intake. Traditional methods of assessing FV intake have limitations, and this is likely to impact on observed associations with disease outcomes and markers of disease risk. Nutritional biomarkers may offer a more objective and reliable method of assessing dietary FV intake. Some single blood biomarkers, such as plasma vitamin C and serum carotenoids, are well established as indicators of FV intake. Combining potential biomarkers of intake may more accurately predict overall FV intake within intervention studies than the use of any single biomarker. Another promising approach is metabolomic analysis of biological fluids using untargeted approaches to identify potential new biomarkers of FV intake. Using biomarkers to measure FV intake may improve the accuracy of dietary assessment.

In this study, we used farm-level data from a university feed-out program to evaluate how the value of feeder cattle ultimately realized through finishing and grid pricing differs from their market value at public auction. Consistent with the theory of factor price disparity, results indicate that significant risk premiums exist in the feeder cattle market. Producers of cattle with known feedlot performance, carcass potential, or both might be better off retaining ownership of their calves or marketing them in a way that communicates the information that is known about their potential performance directly to the buyer.

We present the results of an approximately 6 100 deg2 104–196 MHz radio sky survey performed with the Murchison Widefield Array during instrument commissioning between 2012 September and 2012 December: the MWACS. The data were taken as meridian drift scans with two different 32-antenna sub-arrays that were available during the commissioning period. The survey covers approximately 20.5 h < RA < 8.5 h, − 58° < Dec < −14°over three frequency bands centred on 119, 150 and 180 MHz, with image resolutions of 6–3 arcmin. The catalogue has 3 arcmin angular resolution and a typical noise level of 40 mJy beam− 1, with reduced sensitivity near the field boundaries and bright sources. We describe the data reduction strategy, based upon mosaicked snapshots, flux density calibration, and source-finding method. We present a catalogue of flux density and spectral index measurements for 14 110 sources, extracted from the mosaic, 1 247 of which are sub-components of complexes of sources.

Objectives:
To examine the safety of emergency department (ED) procedural sedation and analgesia (PSA) and the patterns of use of pharmacologic agents at a Canadian adult teaching hospital.
Methods:Retrospective analysis of the PSA records of 979 patients, treated between Aug. 1, 2004, and July 31, 2005, with descriptive statistical analysis. This represents an inclusive consecutive case series of all PSAs performed during the study period.
Results:Hypotension (systolic blood pressure ≤ 85 mm Hg) was documented during PSA in 13 of 979 patients (1.3%; 95% confidence interval [CI] 0.3%–2.3%), and desaturation (Sao2 ≤ 90) in 14 of 979 (1.4%; CI 0.1%–2.7%). No cases of aspiration, endotracheal intubation or death were recorded. The most common medication used was fentanyl (94.0% of cases), followed by propofol (61.2%), midazolam (42.5%) and then ketamine (2.7%). The most frequently used 2-medication combinations were propofol and fentanyl (P/F) followed by midazolam and fentanyl (M/F), used with similar frequencies 58.1% (569/979) and 41.0% (401/979) respectively. There was no significant difference in the incidence of hypotension or desaturation between the P/F and M/F treated groups. In these patients, 9.1% (90/979) of patients received more than 2 different drugs.
Conclusions:Adverse events during ED PSA are rare and of doubtful clinical significance. Propofol/fentanyl and midazolam/fentanyl are used safely, and at similar frequencies for ED PSA in this tertiary hospital case series. The use of ketamine for adult PSA is unusual in our facility.

Sand quarrying in 1989 at Sand Fiold, Sandwick, in Orkney resulted in the accidental discovery of a rock-cut chamber containing a cist. Subsequent excavation revealed that this cist had a number of unusual features. The cist slabs had been fitted together exceptionally well and the completed cist was designed to be re-opened by the removal of a side slab. Within the chamber, access was provided to the opening side of the cist and a relieving structure was built over its capstone.
The cist contained cremation and inhumation burials that had been inserted on more than one occasion; as its builders intended. A collection of poorly preserved unburnt bone was found to comprise the remains of two individuals: a young adult and a foetus. Two collections of cremated bone, each derived from a single adult, were also present; one in a Food Vessel Urn, the second forming a pile on the floor and containing two burnt antler tines and two unburnt human teeth. The un-urned cremation deposit and the unburnt bones had been covered in mats of plant fibres derived from grass and sedge. The urn had been lined with basketry, also made from grass. Outside the cist, an exceptionally large collection of fuel ash slag (FAS), derived from a cremation pyre, had been deposited between the cist and the wall of the rock-cut chamber.
Radiocarbon dates indicate that the site and its contents had a long history. The FAS and the foetus skeleton date to 2900–2500 cal BC. Between 2200 and 1900 cal BC the urned cremation and young adult human bones were inserted and charcoal was deposited in the foundation slots for the back wall of the cist. The deposition of the un-urned cremation was dated to 1000–800 cal BC, some 900 years later, when the urn had already fallen over and broken. At this time, it is assumed that the urn was restored to an upright position and propped with stones, while the stone lid for the urn was reused in the foundation slot of the left-hand side of the cist. Reuse and refurbishment over two millennia seem evidenced in the results from this cist.

Excavations at Eaglestone Flat, on the gritstone eastern uplands of the Peak District, have revealed a Bronze Age cremation cemetery associated with a number of contemporaneous stone structures built for ritual and agricultural purposes. Some of the burials were within urns, mostly cordoned. Others were simply placed in pits whilst still hot. A minority were deposited in direct association with small cairns, either placed under or within them. The majority were on open ground near the stone features and adjacent to the upslope edge of a prehistoric field. Most of the stone structures are clearance features associated with the preparation and cultivation of the land close by over an extended period. They are found in a complex palimpsest, which includes structures of unusual design, such as retained rectangular platforms, and discontinuous walls that were only ever 1–2 courses high and probably surmounted by low banks. A series of radiocarbon results adds to knowledge of the date at which Peak District cairnftelds and field systems were built. Environmental data allows vegetational sequences to be reconstructed.
