Authors: Baker Robert J. , Ogilvie Helen V. , Richards Amanda J. 
Published: September 2010

Abstract
The extraction efficiency of some perfluorinated phenols for the removal of Cs+ and Sr2+ from aqueous solutions is reported. The perfluorinated phenols C6F5OH and 2,3,5,6-C6F4HOH have been shown to extract 90Sr2+ or Cs+ from aqueous solutions into a 100:1 mixture of toluene and pyridine in reasonable efficiencies, using radio-tracer and ICP-OES techniques. Additionally uranium, 59Fe3+ {as a model for Pu(IV)} and Eu3+ {as a model for Am(III)} were investigated, with only iron not being successfully extracted.
Low temperature growth and laser-induced phase transformation of perovskite oxide films for uncooled IR detector applications
Authors: Sarney Wendy , Little John W , Livingston Frank E , Niesz Krisztian , Cole Melanie W , Morse Daniel E 
Published: September 2010

AbstractPyroelectric infrared (IR) detectors based on perovskite oxides are of interest in part because of their lack of need for cooling, which makes them relatively more affordable and operationally simpler than cooled photon detector systems. We are investigating two methods for low-cost growth of perovskite oxide thin films, namely, a bio-inspired, low-temperature synthesis method and a modified industry-standard metalorganic solution deposition (MOSD) method. Subsequent to film synthesis, we utilize direct-write laser phase conversion and micro-electro-mechanical systems (MEMS) fabrication for development of an uncooled IR focal plane array (FPA). Film growth, crystallization and MEMS processes are compatible with monolithic integration of the detector pixels directly onto Si readout integrated circuits (ROICs).

Published: September 2010

AbstractMonodispersed nickel oxide nanoparticles have been synthesized using solution combustion synthesis method. Size of the nanoparticles was controlled by varying different reaction parameters such as reaction temperature and reaction time. Structure and morphology of the nanoparticles were investigated using X-ray diffraction and transmission electron microscopy. BET surface area of 99.7 m2/g was obtained for the nanoparticles synthesized at 300 °C. A decrease in surface area was observed with increase in reaction temperature. The nanoparticles were compacted using spark plasma sintering technique at 950 °C and thermal conductivity was studied on compacted sample. Significant decrease in thermal conductivity was observed for nanoparticles in compared to their bulk counter-part.

Published: September 2010

AbstractThin layers of indium tin oxide (ITO) were deposited onto glass substrates by RF magnetron sputtering with the pressure varying from 6 mTorr to 15 mTorr. The films were annealed in a reducing atmosphere at 500 °C for 30 minutes. Sheet resistance was determined by four-point-probe measurement. Resistivity, mobility, and carrier concentration were obtained by Hall effect measurements. Transmission of the films in the visible spectrum was determined by photospectrometry. The structure of the films was characterized by X-ray diffraction. X-ray photoelectron spectroscopy was used to determine the oxidation state of Sn, which was used to determine the fraction of active tin clusters. The effect of additional anneals was investigated. The results reveal that the lowest resistivity obtained was 1.69×10-4 -cm at 9 mTorr and the highest transmittance of 90% was obtained after a second anneal. However, the second anneal decreased the mobility and conductivity for high sputter pressures.
Analyzing the Mesoscopic Structure of Pericellular Coats on Living Cells

Published: September 2010

AbstractWe employed passive particle-tracking microrheology to map the micromechanical structure of the hyaluronan-rich pericellular coat enveloping chondrocytes. Therefor we exploited the technique's position sensitivity to gain radial information on the coat. We observed a linear increase in viscoelasticity from the coat's rim towards the cell membrane. This gradient corresponds to hyaluronan concentration profiles observed in confocal fluorescent microscopy with small, specific hyaluronan markers. These results suggest that the structural basis of the pericellular coat is formed by grafted hyaluronan of different effective lengths stretched out by a homogenous decoration with hyaladherins such as aggrecan. The different effective lengths could be caused either by different lengths of the HA chains or by “side-on” attachments within the chain. Remarkably, the hyaluronan-rich coat increases the viscosity of the pericellular space only by about a factor of about two at 100 and at 20 Hz compared to pure media and an increasing elastic component is observed. Both the viscoelasticity as well as the hyaluronan concentration decrease linearly or slightly exponential from the cell membrane towards the PCC's rim. These observations could be obtained on living cells exploiting this unintrusive measurement techniques.
Swabbing-Test Interpretation Using Nonlinear Regression in San Jorge Gulf Basin
Authors: Naranjo Euver , Bravo José , Díaz Eugenio , Caldera José 
Published: September 2010

Summary
In the San Jorge basin in southern Argentina, swabbing tests are the conventional testing technique used by YPF to evaluate production potential on those reservoirs that do not flow naturally to surface. During the well-completion phase, a swabbing device is lowered into the wellbore to test each reservoir layer individually. These wells, which produce from multilayer formations, are later completed for commingled production. Accordingly, the swabbing test represents the only opportunity to measure dynamic properties for each individual layer.
So far, pressure-transient analysis of such tests has been limited to the use of conventional interpretation methods applied to the infinite-acting radial-flow (IARF) portion on those tests in which such a flow regime is observed. This can happen if a bottomhole shut-in valve is used or if the shut-in period is given a long enough time for the bottomhole pressure to reach conditions close to initial reservoir pressure. Unfortunately, both practices increase the completion cost substantially, which affects well economics strongly. As a result of this economic limitation, neither practice is applied on a routine basis, so most of the time, transient-pressure interpretation is not performed.
In an attempt to obtain value from routine swabbing tests, where an IARF condition is not observed, a different method of test interpretation has been introduced. Through the computation of the instantaneous flow rate from the pressure-trend increase during the swabbing period, it is possible to use nonlinear numerical regression to make an estimation of the reservoir permeability, even if IARF is not present.
With this innovative approach, YPF is constructing for the first time representative production models for each well, thereby improving reserves estimations and production forecasts.
Hydrajet Testing Under Deep-Well Conditions Points to New Requirements for Hard-Rock Perforating
Authors: Surjaatmadja Jim B. , Bailey Andrew , Sierra Silverio 
Published: September 2010

Summary
The use of hydrajetting for perforating wells has been common since the 1960s. During those early years, wells were relatively shallow, and jetting success was demonstrated consistently. However, as wells were drilled to depths where rock formations were harder, performance of hydrajetting became less dependable because subsequent stimulation failures occurred more often from the lack of fracture initiation.
To help prevent this situation, a series of tests was performed to define new best practices for hydrajet perforating of rock under high ambient pressure. Various rocks were subjected to the tests that were conducted using different jetting pressures and abrasives. To understand the jetting behavior better, the mechanical characteristics (such as Young's moduli, Poisson's ratios, and compressive strengths) were also evaluated.
This paper discusses various tests results, and new constraints for jetting are defined and presented.
An Update on the Use of Reservoir Analogs for the Estimation of Oil and Gas Reserves
Authors: Sidle R.E.. E. , Lee W.J.. J. 
Published: September 2010

Summary
Since a prior paper on analogy for estimating petroleum reserves (Hodgin and Harrell 2006), new dimensions of this topic have emerged. This paper provides updated guidance for analogy use and explains new concepts for the application of analogy in reserves estimation and classification.
Reserves evaluators using engineering and geoscience techniques now have new petroleum-reserves rules that include the use of analogy. In 2007, SPE finalized the Petroleum Resource Management System (PRMS) instructions, and in late 2008, the US Securities and Exchange Commission (SEC) published updated regulations on reserves reporting. Recent papers (Lee 2009; Etherington 2009) provide good summaries of the updated SEC rules and a comparison to PRMS. This paper will provide guidance to aid understanding of and compliance with these rules as related to the use of analogs.
The paper provides interpretations of new analogy-related terminology and the related reserves rules. It also gives examples of how these interpretations can be applied to common reserves-estimation situations where analogy is used. The paper also addresses new concepts concerning how analogies can be shown as valid and can be adjusted for minor differences in the comparison of target field with analogy field.
The recent publication of the US SEC reserves reporting rules, which draw partially from the SPE PRMS, has increased interest in deeper understanding of both these SEC rules and PRMS. This paper will assist those who develop and use petroleum-reserves data in understanding how the use of analogy can contribute to reliable reserves estimates and proper classification. Please note that the opinions expressed in this paper are those of the authors alone. They represent the opinions of neither the US SEC nor its staff members.
CO2 EOR Potential in Naturally Fractured Haft Kel Field, Iran
Authors: Alavian Sayyed Ahmad , Whitson Curtis H. 
Published: September 2010

Summary
We present results studying the enhanced-oil-recovery (EOR) potential for carbon dioxide (CO2) injection in the naturally fractured Haft Kel field, Iran, on the basis of detailed compositional simulations of a homogeneous single matrix block surrounded by fractures. Oil recoveries from CO2 injection in this idealized model approach 90% for reservoir pressures of 1,400 psia and higher (i.e., at and above current reservoir pressure of 1,500–1,800 psia). It is expected that heterogeneity will reduce recovery on the field scale. This compares with 15–25% recoveries reported for gas-cap expansion and/or injection of hydrocarbon (HC) gas.
Fundamentally different recovery mechanisms develop above and below 2,000 psia, the pressure at which CO2 density equals the reservoir-oil density. At lower pressures, CO2 is less dense than reservoir oil and traditional gas/oil gravity segregation results, with a highly efficient process driven by gravity, compositional effects, and interfacial-tension (IFT) gradients that cause capillary-induced oil flow. At pressures greater than 2,000 psia, CO2 density is greater than reservoir-oil density, resulting in an unusual gravity-drainage mechanism whereby CO2 enters the bottom of a matrix block and pushes oil out the sides and top of the matrix block.
The effect of several key parameters has been studied in detail—matrix permeability, matrix-block size, matrix/matrix capillary continuity (stacked blocks), and the use of mixtures of CO2 and HC gas. One of the key results is how the rate of recovery differs for combined injection of HC gas and CO2, and how it varies for CO2 injection for different model parameters.
EOR results are affected by grid sensitivity. Grid effects have been quantified and compared for different model parameters. Final EOR assessment is made using models in which sufficient grid refinement is used to minimize grid sensitivity.
Neolithic Pits, a Bronze Age Cremation and an Early Iron Age Ring-Ditch at Newton Farm, Cambuslang, Lanarkshire
Authors: O'Brien Leonora , Clements Victoria , Roy Mike , Macnab Neil 
Published: September 2010

Fieldwork at Newton Farm, Cambuslang (NGR NS 672 610) was undertaken in advance of housing development in 2005–6. A cluster of six shallow Neolithic pits were excavated, and a collection of 157 round-based, carinated bowl sherds and a quern fragment were recovered from them. The pits produced a date range of 3700 to 3360 cal BC. Most of the pits yielded burnt material, and one of the pits showed evidence of in situ burning. The pottery may form ‘structured deposits’. A Bronze Age adult cremation placed in a Food Vessel dated to 3610±30 BP (2040–1880 cal BC) was set in a wider landscape of single and multiple cremations and inhumations on the river terraces overlooking the Clyde. A possible unurned cremation was also identified. This was cut by the course of a small ring-ditch dated to the very late Bronze Age or early Iron Age 2520±30 BP (800–530cal BC).

Reversed‐Phase High Performance Liquid Chromatography of Proteins
Authors: Josic Djuro , Kovac Spomenka 
Published: September 2010

AbstractReversed‐phase HPLC (RP‐HPLC) is one of most important techniques for protein separations and the method of choice for peptide separation. RP‐HPLC has been applied on the nano, micro, and analytical scale, and has also been scaled up for preparative purifications, to large industrial scale. Because of its compatibility with mass spectrometry, RP‐HPLC is an indispensable tool in proteomic research. With modern instrumentation and columns, complex mixtures of peptides and proteins can be separated at attomolar levels for further analysis. In addition, preparative RP‐HPLC is often used for large‐scale purification of proteins. This unit provides protocols for packing and testing a column, protein separation by use of gradient or step elution, desalting of protein solutions, and separation of enzymatic digests before mass spectrometric analyses. A protocol is also provided for cleaning, regenerating, and storing reversed‐phase chromatography columns. Curr. Protoc. Protein Sci. 61:8.7.1‐8.7.22. © 2010 by John Wiley & Sons, Inc.
Clump Passaging and Expansion of Human Embryonic and Induced Pluripotent Stem Cells on Mouse Embryonic Fibroblast Feeder Cells
Authors: Hartung Odelya , Huo Hongguang , Daley George Q. , Schlaeger Thorsten M. 
Published: September 2010

AbstractThe ability of human embryonic stem cells (hESCs) to differentiate into essentially all somatic cell types has made them a valuable tool for studying human development and has positioned them for broad applications in toxicology, regenerative medicine, and drug discovery. This unit describes a protocol for the large‐scale expansion and maintenance of hESCs in vitro. hESC cultures must maintain a balance between the cellular states of pluripotency and differentiation; thus, researchers must use care when growing these technically demanding cells. The culture system is based largely on the use of a proprietary serum‐replacement product and basic fibroblast growth factor (bFGF), with mouse embryonic fibroblasts as a feeder layer. These conditions provide the basis for relatively inexpensive maintenance and expansion of hESCs, as well as their engineered counterparts, human induced pluripotent stem cells (hiPSCs). Curr.
