description: The aim of this investigation was to discover the extent to which the counselling of students is acceptable to academic members of staff, with particular reference to those in Scottish Universities, and whether or not this is seen to be an integral part of the educational experience provided by a university. The methods used to carry out the study were a questionnaire which included an Attitude Survey, structured interviews and discussions with key informants. A random sample of 50% of members of academic staff was taken from a sample of Scottish Universities. In this study, 75% of the respondents in the two Universities held a negative view towards the counselling of students or were in conflict with regard to it. The counselling service was perceived only as an agency which might provide help for a few students with intractable problems. Counselling was not recognised as being an integral part of the educational experience provided by a university. Nevertheless, members of academic staff did profess to "counsel" students themselves although without any recognised training in the field. Furthermore, strong resistance was shown to any suggestion that academic staff needed to undertake training to acquire the necessary skills. Consequently, members of academic staff and counsellors failed to form a close liaison thus limiting the work of the counselling service.

description: Quantitative real time PCR (RT-PCR) is widely used as the gold standard for clinical detection of SARS-CoV-2. However, due to the low viral load specimens and the limitations of RT-PCR, significant numbers of false negative reports are inevitable, which results in failure to timely diagnose, cut off transmission, and assess discharge criteria. To improve this situation, an optimized droplet digital PCR (ddPCR) was used for detection of SARS-CoV-2, which showed that the limit of detection of ddPCR is significantly lower than that of RT-PCR. We further explored the feasibility of ddPCR to detect SARS-CoV-2 RNA from 77 patients, and compared with RT-PCR in terms of the diagnostic accuracy based on the results of follow-up survey. 26 patients of COVID-19 with negative RT-PCR reports were reported as positive by ddPCR. The sensitivity, specificity, PPV, NPV, negative likelihood ratio (NLR) and accuracy were improved from 40% (95% CI: 27–55%), 100% (95% CI: 54–100%), 100%, 16% (95% CI: 13–19%), 0.6 (95% CI: 0.48–0.75) and 47% (95% CI: 33–60%) for RT-PCR to 94% (95% CI: 83–99%), 100% (95% CI: 48–100%), 100%, 63% (95% CI: 36–83%), 0.06 (95% CI: 0.02–0.18), and 95% (95% CI: 84–99%) for ddPCR, respectively. Moreover, 6/14 (42.9%) convalescents were detected as positive by ddPCR at 5–12 days post discharge. Overall, ddPCR shows superiority for clinical diagnosis of SARS-CoV-2 to reduce the false negative reports, which could be a powerful complement to the RT-PCR.

description: A select panel of oil resource analysts, convened in August 1992 by the Bureau of Economic Geology, The University of Texas at Austin, and the National Institute for Petroleum and Energy Research (NIPER) at the request of the U.S. Department of Energy, concludes that the remaining, recoverable volume of crude oil in the United States ranges from 99 to 204 billion barrels, inclusive of 25 billion barrels of oil carried as proved reserves by the Energy Information Administration at the end of 1991. The range in estimates reflects different assumptions of price and technology (including the geological ability to apply that technology). The lower estimate assumes a stable oil price of $20 per barrel (1992 dollars) with existing technology. The higher estimate assumes a price of $27 per barrel (1992 dollars) but with advanced technology. The range in estimates of the remaining resource base recoverable under the given assumptions is equivalent to 35 to 75 years of continued U.S. crude oil production at the current annual rate of 2.7 billion barrels.

description: In this paper we study the near-field thermodynamics of a photon gas at equilibrium as well as out-of-equilibrium in the presence of dissipative effects. As a consequence of Heisenberg's uncertainty principle, we are able to eliminate the low-frequency modes in both cases, providing an analytical expression for the near-field entropy. In addition, we obtain the entropic-force contributions to the Casimir effect. At zero temperature the well-known $l^{-4}$ behavior of the pressure is obtained. In the nonequilibrium case, we compute the entropy production, showing that the excess of heat in each bodies must be dissipated into the respective thermal reservoirs.

description: Outcrop mapping, field permeability measurements, petrographic analyses, petrophysical measurements, and pore-level modeling studies are being conducted on exposures of the Ferron Sandstone, east-central Utah, to develop a better understanding of the dimensions and internal arrangement of flow units, baffles, and barriers in sandstone gas reservoirs. The ultimate goals of this work are to establish methods for applying outcrop studies to reservoir characterization and to develop reservoir models that will guide infill drilling to maximize incremental gas reserve growth from fluvial-deltaic sandstone reservoirs. Activities during the second year of this 3-year project focused on data collection and preliminary interpretations. Mapping and field permeability measurements were initiated on the seaward-stepping Ferron unit 2 sandstone. These results will provide a comparison with data collected during the 1990 field season when landward-stepping sandstones of Ferron unit 3 were examined. Framework grain and cement mineralogy and the composition of intergranular material were quantified for selected samples from unit 3. Petrophysical measurements were completed on 24 specimens from units 2, 4, and 3. Sections of the pore-level modeling code were rewritten to improve accuracy and efficiency, and scenarios were developed to model the effects of grain size, cementation, and compaction on porosity, single-phase permeability, and formation factor. Preliminary results indicate that important differences exist in the internal geometry of landward- and seaward-stepping fluvial-deltaic sandstones. It was also found that closer-spaced permeability measurements improved the resolution of permeability structure. Petrographic studies documented differences in composition between fluvial, transgressive, delta-front, and distributary-channel sandstones; these differences in rock composition are reflected by differences in the mean permeability of these facies as measured on outcrop. Initial comparisons of pore-level model results with measured petrophysical properties are encouraging and suggest that refinements based on examination of the analyzed samples will lead to a close match between observed and modeled behavior.

description: We prove that for a hard core interaction the ground state spin polarization in the low Zeeman energy limit is given by $P=2/ν-5$ for filling fractions in the range $ 1/3 \leqν\leq 2/5 $. The same result holds for a Coulomb potential except for marginally small magnetic fields. At the magnetic fields $B<20T$ unpolarized quasielectrons can manifest themselves by a characteristic peak in the I-V characteristics for tunneling between two $ν=1/3$ ferromagnets.

description: We present an entirely fiber based laser source for non-linear imaging with a novel approach for multi-color excitation. The high power output of an actively modulated and amplified picosecond fiber laser at 1064 nm is shifted to longer wavelengths by a combination of four-wave mixing and stimulated Raman scattering. By combining different fiber types and lengths, we control the non-linear wavelength conversion in the delivery fiber itself and can switch between 1064 nm, 1122 nm, and 1186 nm on-the-fly by tuning the pump power of the fiber amplifier and modulate the seed diodes. This is a promising way to enhance the applicability of short pulsed laser diodes for bio-molecular non-linear imaging by reducing the spectral limitations of such sources. In comparison to our previous work [1, 2], we show for the first time two-photon imaging with the shifted wavelengths and we demonstrate pulse-to-pulse switching between the different wavelengths without changing the configuration.

description: Prospect of building electronic devices in which electron spins store and transport information has revived interest in the spin relaxation of conduction electrons. Since spin-polarized currents cannot flow indefinitely, basic spin-electronic devices must be smaller than the distance electrons diffuse without losing its spin memory. Some recent experimental and theoretical effort has been devoted to the issue of modulating the spin relaxation. It has been shown, for example, that in certain materials doping, alloying, or changing dimensionality can reduce or enhance the spin relaxation by several orders of magnitude. This brief review presents these efforts in the perspective of the current understanding of the spin relaxation of conduction electrons in nonmagnetic semiconductors and metals.

description: Significant progress has been made in the delineation, measurement, and description of a perched aquifer(s) in the region of the U.S. Department of Energy Pantex Plant, and in the determination of hydraulic characteristics of perched aquifers. Major areas of progress include documentation of the spatial extent of the perched aquifer and of mechanisms controlling directions and rates of ground-water flow. New data have been collected from (1) aquifer tests performed in five perched aquifer monitoring wells at the Pantex Plant, (2) static water-level measurements in six new perched aquifer monitoring wells drilled at the Pantex Plant in the spring of 1992, (3) regional surveys conducted to locate domestic and agricultural wells producing from either the perched aquifer that extends under the Pantex Plant or from a possibly separate perched aquifer in the region of interest, and (4) extensive chemical and isotopic sampling of waters produced from the perched aquifer. Hydrologic results derived from these data will be discussed in this report, and chemical results will be reviewed in a separate report.

We prove that every bi-warped product submanifold of the form $M=M_T\times_{f_1}\! M_\perp\times_{f_2}\! M_θ$ in a nearly Kaehler manifold satisfies the following sharp inequality: $$\|h\|^2\geq 2p\|\nabla (\ln f_1)\|^2+4q\left(1+{\small \frac{10}{9}}\cot^2θ\right)\|\nabla(\ln f_2)\|^2,$$ where $p=\dim M_\perp$, $q=\frac{1}{2}\dim M_θ$, and $f_1,\,f_2$ are smooth positive functions on $M_T$. We also investigate the equality case of this inequality. Further, some applications of this inequality are also given.

description: The potential for secondary incremental recovery of natural gas exists in complex fluvial-deltaic reservoirs of the Texas Gulf Coast. Four deltaic parasequences were identified using well logs calibrated to cores in the G sandstone. Engineering evaluations of production performance and pressures are compared with reservoir facies; these evaluations demonstrate the importance of identifying reservoir facies in maximizing recovery of natural gas. A well-log-based model to predict the free-water level and effective gas permeabilities was tested and calibrated using Wilcox gas reservoirs. Key reservoir parameters of porosity, water saturation, permeability, and capillary pressure are related in a single equation. Analysis of natural gas reservoirs from the Wilcox Deltaic sandstones in the Houston Embayment (WX-1) in East Texas indicates that reserve growth potential of approximately 60 percent over the current estimate of ultimate recovery is possible in deltaic sandstone reservoirs in the Lake Creek Unit. Detailed geologic, engineering, and petrophysical evaluation of the G sandstone reservoir in the Lake Creek Unit indicates that the maximum additional incremental gas opportunities exist in the flank region adjacent to the area currently developed in the Lake Creek field. The location, number, and economic feasibility of additional wells required to convert this resource to producible reserves were not evaluated.

description: The nuclei of most normal galaxies contain supermassive black holes, which can accrete gas through a disk and become active. These Active Galactic Nuclei, AGN, can form jets which are observed on scales from AU to Mpc and from meter wavelengths to TeV gamma ray energies. High resolution radio imaging and multi-wavelength/messenger campaigns are elucidating the conditions under which this happens. Evidence is presented that: AGN jets are formed when the black hole spins and the accretion disk is strongly magnetized, perhaps on account of gas accretingat high latitude beyond the black hole sphere of influence; AGN jets are collimated close to the black hole by magnetic stress associated with a disk wind; higher power jets can emerge from their galactic nuclei in a relativistic, supersonic and proton-dominated state and they terminate in strong, hot spot shocks; lower power jets are degraded to buoyant plumes and bubbles; jets may accelerate protons to EeV energies which contribute to the cosmic ray spectrum and which may initiate pair cascades that can efficiently radiate synchrotron gamma rays; jets were far more common when the universe was a few billion years old and black holes and massive galaxies were growing rapidly; jets can have a major influence on their environments, stimulating and limiting the growth of galaxies. The observational prospects for securing our understanding of AGN jets are bright.

description: To enhance our understanding of the internal structure of salt stocks, we conducted 30 centrifuge experiments that produced hundreds of model diapirs under artificial acceleration generally equivalent to 1,200 times that of normal gravity. Most of these experiments were geometrically and dynamically scaled to be equivalent to U.S. Gulf Coast salt domes. The domes were modeled under static overburdens and, for the first time, under aggrading and prograding overburdens. This report focuses on the internal structure of mushroom-shaped domes, which theoretically exist in nature and are demonstrated in natural examples in the U.S. Gulf Coast, Canada, and West Germany. The experimental results enable the extremely complex internal structure of mushroom-shaped salt domes to be recognized and understood. This recognition is vital because a mushroom structure would threaten the integrity of a hypothetical repository by creating a plumbing system composed of country rocks infolded from below the diapir cap and extending to near the dome center.

description: The economical lifetime of the divertor is a key concern for realizing nuclear fusion reactors that may solve the world's energy problem. A main risk is thermo-mechanical failure of the plasma-facing tungsten monoblocks, as a consequence of irradiation hardening induced by neutron displacement cascades. Lifetime extensions that could be carried out without prolonged maintenance periods are desired. In this work, the effects of potential treatments for extending the lifetime of an operational reactor are explored. The proposed treatments make use of cyclic recrystallization processes that can occur in neutron-irradiated tungsten. Evolution of the microstructure under non-isothermal conditions is investigated, employing a multi-scale model that includes a physically-based mean-field recrystallization model and a cluster dynamics model for neutron irradiation effects. The model takes into account microstructural properties such as grain size and displacement-induced defect concentrations. The evolution of a hardness indicator under neutron irradiation was studied. The results reveal that, for the given microstructure and under the assumed model behaviour, periodical extra heating can have a significant positive influence on controlling the irradiation hardening. For example, at 800 C, if extra annealing at 1200 C was applied after every 100 hrs for the duration of 1 hr, then the hardness indicator reduces from maximum 140 to below 70.

description: We present an improved method to measure the rotation curves for disks with non-axisymmetric brightness profiles initially published in Teague et al. (2018a). Application of this method to the well studied AS$~$209 system shows substantial deviations from Keplerian rotation of up to $\pm 5\%$. These deviations are most likely due to perturbations in the gas pressure profile, including a perturbation located at $\approx 250~$au and spanning up to $\approx 50~$au which is only detected kinematically. Modelling the required temperature and density profiles required to recover the observed rotation curve we demonstrate that the rings observed in $μ$m scattered light are coincident with the pressure maxima, and are radially offset from the rings observed in mm continuum emission. This suggests that if rings in the NIR are due to sub-$μ$m grains trapped in pressure maxima that there is a vertical dependence on the radius of the pressure minima.

description: The Upper Pennsylvanian (lower Missourian) Cleveland Formation produces gas from low-permeability ("tight") sandstone reservoirs in the western Anadarko Basin of the northeastern Texas Panhandle. In this six-county region, these reservoirs had produced more than 412 Bcf of natural gas through December 31, 1989. Because of their typically low permeability, the Cleveland sandstones require acidizing and hydraulic fracture treatment to produce gas at economic rates. Since 1982, the Gas Research Institute has supported geological investigations throughout the United States to develop the scientific and technological knowledge for producing from low-permeability, gas-bearing sandstones. As part of this program and the GRI Tight Gas Sands project, the Bureau of Economic Geology has been conducting research on low-permeability sandstones in the Cleveland Formation and on several other sandstone units of similar character in Texas and Wyoming. This effort is part of a broader program to increase the understanding and ultimate utilization of gas resources in these low-permeability formations through regional and field-specific geology, formation evaluation, and reservoir engineering. This report summarizes findings on the regional geology, depositional setting, sequence stratigraphy, and petrology of the Cleveland Formation. Geological research on the Cleveland began with an effort to choose a formation in which to drill Staged Field Experiment (SFE) well number 4, the latest in a series of SFE wells drilled since 1986 to conduct geological and engineering research on low-permeability gas reservoirs. Although the Cleveland Formation was not chosen for SFE No. 4, investigation of this low-permeability, gas-bearing sandstone continued with the drilling of cooperative wells in the unit. Because the Cleveland Formation contains an estimated 38 Tcf of gas in place, development of advanced technology and understanding that can be applied to this and other tight gas formations will have a positive impact on gas supply by improving gas recovery and lowering completion costs.

We show that the ghost instabilities which are at the heart of the no-go theorem, can indeed be avoided. The wormhole solutions with the latter property are, however, strongly fine tuned, and hence it is likely that they are unstable. Furthermore, it remains unclear whether these solutions have other pathologies, like gradient instabilities along angular and radial directions.

description: An analysis of infield completions and reserve growth potential was made in Tertiary non-associated gas reservoirs in South Texas. Infield well completions were defined from a concurrent GRI project involving macro-scale prediction of reserve growth. This report validates 78 percent, or 5.6 Tcf, of a high-end infill estimate of 7.2 Tcf for nine stratigraphic units in South Texas. This is a significant resource volume given the historical expectation that natural gas can be efficiently drained with widely spaced wells (1 or 2 per square mile) in conventional reservoirs. Groups of infield completions, or reservoir sections, from Frio, Vicksburg, Wilcox, and Miocene reservoirs were examined using geophysical well logs and production and pressure analyses. Seven reservoir-section types that contributed to the macro reserve growth estimate were evaluated. About 20 percent of the estimate consists of gas volumes extrapolated using consolidated reservoir groups, cycled reservoirs, and reservoirs with invalid data. Additional gas volumes in the estimate were extrapolated from reservoir sections representing rate acceleration. The estimate also includes reservoir volumes from the low-permeability Wilcox Lobo trend, where limited drainage radii lead to expected reserve growth. Volumes that represent within-reservoir reserve growth and volumes that represent shallower- or deeper-pool reservoirs determined not to be in pressure communication with preceding completions in a reservoir section formed most of the macro reserve growth estimate.

description: Geologic and hydrologic analysis of the Upper Cretaceous Mesaverde Group shows that the major controls on the production of coalbed methane are: structural configuration, coal occurrence, gas content, hydrodynamics, and water production. Steep structural dip (500 ft/mi) and coal occurrence limit economic exploration to the eastern and southeastern margins of the basin. Coal resources occur mainly in the lower Williams Fork Formation (upper Mesaverde) in the eastern part of the basin. Most coal beds are high-volatile C to B bituminous rank and have gas contents of less than 200 scf/ton. Moreover, Williams Fork coals do not extend westward to the area of highest thermal maturity. Thus, they could not serve as conduits for long-distance migration of gas. Regionally, groundwater flows westward from an eastern recharge area across an area of low thermal maturity up the coal-rank gradient. Consequently, only a relatively small volume of gas may be available to be swept basinward for conventional trapping. The most prospective areas lie basinward, northwest of Craig, Colorado, on the upflow, downward side of a major fault zone. Gas contents in some coal beds on the downthrown side of the fault exceed 400 scf/ton. The Mesaverde is a thick, regionally interconnected aquifer system of high transmissivity, yielding large volumes of water. Paradoxically, coalbed permeabilities of 10's to 1,000's of md may be too high for economic gas production. To date, high water production and low gas content at the basin margins have limited coalbed activity in the Sand Wash Basin. Major Tertiary coal resources occur in the lower part of the Paleocene Fort Union Formation.

description: We investigate the breakdown of disordered networks under the action of an increasing external---mechanical or electrical---force. We perform a mean-field analysis and estimate scaling exponents for the approach to the instability. By simulating two-dimensional models of electric breakdown and fracture we observe that the breakdown is preceded by avalanche events. The avalanches can be described by scaling laws, and the estimated values of the exponents are consistent with those found in mean-field theory. The breakdown point is characterized by a discontinuity in the macroscopic properties of the material, such as conductivity or elasticity, indicative of a first order transition. The scaling laws suggest an analogy with the behavior expected in spinodal nucleation.

description: Oxidized uranium ore deposits were discovered in the Deweesville sandstone (also referred to as the Stones Switch; Bunker and MacKallor [1973]) in the Falls City region in the 1950s. Uranium was mined and milled in the small community of Deweesville by Susquehanna-Western, Inc. (SWI) from April 1961 to August 1973. Tailings composed of sediment residue from the sulfuric acid milling process and residual sulfuric acid solutions were disposed of in six ponds on the outcrop of the Deweesville, within the mined-out uranium pits in the Deweesville, and on the outcrop of the Conquista, creating a set of large tailings impoundments (figs. 1.1 and 1.2). From 1978 to 1982 Solution Engineering, Inc. (SEI) conducted a secondary recovery of the remaining uranium in the tailings piles by in situ leaching. In 1984, the ponds on top of two of the tailings piles were spray evaporated and a clay cap was placed over the piles to prevent additional percolation of water through the piles and into the underlying aquifers. Acidic tailings solutions have been recharging the underlying aquifers since initial tailings disposal and may still be leaking into these aquifers. Several hydrogeologic investigations have been conducted to assess whether there has been groundwater contamination from the tailings. Early studies were conducted by Turk, Kehle and Associates (1976), and Ford, Bacon & Davis Utah (1978, 1981). Each of these studies included only minor investigations of the hydrogeology and hydrochemistry of the site and, in general, underestimated the extent of contamination from the site. Investigations conducted by the U.S. Department of Energy (DOE) from 1985 to 1991 have since revealed the true extent of contamination (U.S. Department of Energy, 1991).

description: Lentiviruses harbour high genetic variability for efficient evasion from host immunity. An attenuated equine infectious anaemia (EIA) vaccine was developed decades ago in China and presented remarkably robust protection against EIA. The vaccine was recently proven to have high genomic diversity, particular in env. However, how and to what extent the high env diversity relates to immune protection remains unclear. In this study, we compared immune protections and responses of three groups of horses stimulated by the high-diversity vaccine EIAV_HD, a single molecular clone of the vaccine EIAV_LD with low env diversity, as well as a constructed vaccine strain EIAV_MD with moderate env diversity. The disparity of virus-host interactions between three env diversity-varied groups (5 horses in each group) was evaluated using clinical manifestation, pathological scores, and env-specific antibody. We found the highest titres of env antibodies (Abs) or neutralizing Abs (nAbs) in the EIAV_HD group, followed by the EIAV_MD group, and the lowest titres in the EIAV_LD group (P<0.05). The occurrence of disease/death was different between EIAV_HD group (1/0), EIAV_MD (2/2), and EIAV_LD group (4/2). A similar env diversity-related linear relationship was observed in the clinical manifestations and pathological changes. This diversity-dependent disparity in changes between the three groups was more distinct after immunosuppression, suggesting that env diversity plays an important role in protection under low host immunocompetence. In summary, inoculation with vaccines with higher genetic diversity could present broader and more efficient protection. Our findings strongly suggest that an abundance of Env antigens are required for efficient protection against lentiviruses.
Behavior of excitonic levels in symmetric and asymmetric double quantum wells in a magnetic field

description: We studied theoretically the excitonic energy levels and the optical absorption spectra for double quantum wells, both symmetric and asymmetric, in the presece of an homogeneous magnetic field. Within the effective mass approach, we expanded the excitonic wave function, in an orthogonal basis formed by products of electron and hole wave functions in the growth direction z, and one particle solutions of the magnetic Hamiltonian in the x-y plane. We applied our method to the case of Al_xGa_{1-x}As, for which we showed how the exciton wave function vary, and how the basis functions are mixed in a non trivial way by the effect of the Coulomb potential. By taking into account all the mixing between the elements in our base, we get anti-crossing between excited excitonic states not reported previously.

description: We apply the model relating halo concentration to formation history proposed by Ludlow et al. to merger trees generated using an algorithm based on excursion set theory. We find that while the model correctly predicts the median relation between halo concentration and mass, it underpredicts the scatter in concentration at fixed mass. Since the same model applied to N-body merger trees predicts the correct scatter, we postulate that the missing scatter is due to the lack of any environmental dependence in merger trees derived from excursion set theory. We show that a simple modification to the merger tree construction algorithm, which makes merger rates dependent on environment, can increase the scatter by the required amount, and simultaneously provide a qualitatively correct correlation between environment and formation epoch in the excursion set merger trees.
