description: Open clusters are groups of stars that form at the same time, making them an ideal laboratory to test theories of star formation, stellar evolution, and dynamics in the Milky Way disk. However, the utility of an open cluster can be limited by the accuracy and completeness of its known members. Here, we employ a "top-down" technique, {\it extreme deconvolution gaussian mixture models} (XDGMM), to extract and evaluate known open clusters from Gaia DR2 by fitting the distribution of stellar parallax and proper motion along a line-of-sight. Extreme deconvolution techniques can recover the intrinsic distribution of astrometric quantities, accounting for the full covariance matrix of the errors; this allows open cluster members to be identified even when presented with relatively uncertain measurement data. To date, open cluster studies have only applied extreme deconvolution to specialized searches for individual systems. We use XDGMM to characterize the open clusters reported by Ahumada et al. 2007 and are able to recover 420 of the 426 open clusters therein (98.1\%). Our membership list contains the overwhelming majority ($>95\%$) of previously known cluster members. We also identify a new, significant, and relatively faint cluster member population and validate their membership status using Gaia eDR3. We report the fortuitous discovery of 11 new open cluster candidates within the lines of sight we analyzed. We present our technique, its advantages and challenges, as well as publish our membership lists and updated cluster parameters.

A remote sensing based multilevel rangeland classification for the Lac-Du-Bois rangelands, Kamloops, British Columbia
Creators: name: Watson, Edward Kent
Publisher: name: University of British Columbia
Year: 2010

description: With 1.2 million hectares of open grassland and 6 million hectares of forested rangeland in British Columbia, a classification and Inventory system had to be developed for rangeland which could be compiled quickly, accurately, and on an annual basis with minimal time spent collecting ground data. Remote sensing techniques provided the tool whereby large tracts of land were classified, inventoried and monitored. The major objective of this study was to use multiscale and multidate remote sensor data to produce a rangeland classification and legend for the open grassland of the Lac-du-Bois range located north of Kamloops, British Columbia. Aerial photography, obtained at various scales and dates throughout the summers of 1975 and 1976, was used to produce a range inventory map of the Lac-du-Bois area. Landsat maps were prepared from September 1972, July 1973 and July 1975 imagery. The developed classification legend was based on an ecologically-based, remote-sensing legend and was expanded for the central interior of British Columbia. The developed rangeland legend is hierarchical in format, flexible, expandable and adaptable to other rangeland areas. Six boundary type-lines were designed to separate (1) sharp distinct changes in vegetation types; (2) to indicate a known transition or ecotone between verified types; (3) to denote interpreted boundaries between known types; (4) to map interpreted vegetation areas; (5) to indicate fencelines boundaries, and (6) to indicate obscured land. Landsat maps produced from 1972, 1973 and 1975 imagery provided a broad overview of the major range types found on the Lac-du-Bois range. Landsat imagery combined with small scale, 1:63,000 colour and colour-infrared photography provided the first step in the inventory phase. 1:20,000 colour and colour-infrared photography is not recommended for detailed range inventory mapping since the entire study area requires ground work. 1:10,000 colour and colour-infrared original diapositives provide the required detail to identify range types and the species present without spending unnecessary time in the field. Original 1:10,000, colour and colour-infrared diapositives must be employed for interpretation purposes. Paper prints are required for field work. Species identification was possible on large scale 1:4,000 original colour-infrared diapositives. The range classification was developed and a inventory map of the Lac-du-Bois range was produced which illustrates the classification legend and boundary types.

The uses of graphics in planning
Creators: name: Farevaag, Marta
Publisher: name: University of British Columbia
Year: 2010

description: Practicing planners spend a substantial portion of their time and budgets preparing and using planning graphics. Yet very little literature exists within the planning field which attempts to investigate the uses of graphics for the profession. Hence, the thesis sets out an introductory framework for applying both current planning practices and knowledge about graphics from other fields to the role of graphics in the planning process. Current planning practices were investigated in a series of interviews with representatives of two groups in the Vancouver area: planners and graphic artists who prepare the bulk of their work for planning purposes. The information obtained in these interviews is presented in detailed form in Chapter 1 and is summarized and analyzed in Chapter 2. The literature on graphics was reviewed for those aspects which seem suggestive for planning applications. In Chapter 3, general theories which discuss the role of graphics in cognitive processes and in the communication of ideas are presented. Theories relating to the functions of various elements in graphics are the subject matter of Chapter 4. Specifically, principles of perceptual psychology, colour theory, typography, the use of symbols, and the choice of appropriate graphic media are investigated. Finally, a number of conclusions are drawn regarding both the current graphic practices within the planning profession and the theoretically optimal use of graphics., The conclusions are, therefore, related both to the topics discussed in the interviews and to the review of relevant literature. Furthermore, these conclusions suggest a variety of improvements in both planning practice and education.

description: We use HST/ACS images and a photometric catalog of the COSMOS field to analyze morphologies of the host galaxies of approximately 400 AGN candidates at redshifts 0.3 < z < 1.0. We compare the AGN hosts with a sample of non-active galaxies drawn from the COSMOS field to match the magnitude and redshift distribution of the AGN hosts. We perform 2-D surface brightness modeling with GALFIT to yield host galaxy and nuclear point source magnitudes. X-ray selected AGN host galaxy morphologies span a substantial range that peaks between those of early-type, bulge-dominated and late-type, disk-dominated systems. We also measure the asymmetry and concentration of the host galaxies. Unaccounted for, the nuclear point source can significantly bias results of these measured structural parameters, so we subtract the best-fit point source component to obtain images of the underlying host galaxies. Our concentration measurements reinforce the findings of our 2-D morphology fits, placing X-ray AGN hosts between early- and late-type inactive galaxies. AGN host asymmetry distributions are consistent with those of control galaxies. Combined with a lack of excess companion galaxies around AGN, the asymmetry distributions indicate that strong interactions are no more prevalent among AGN than normal galaxies. In light of recent work, these results suggest that the host galaxies of AGN at these X-ray luminosities may be in a transition from disk-dominated to bulge-dominated, but that this transition is not typically triggered by major mergers.

ABSTRACTThis work aimed to explore a novel method for augmenting the fresh water production rate of solar stills (SSs) through utilizing nanoparticles of reduced graphene oxide (rGO) and copper oxide (CuO) mixed black paint coating on absorber to increase the solar absorption and evaporation rate. The three types of SS with absorber plate only coated with black paint (CSS), absorber coated with rGO doped in black paint and absorber coated with CuO doped in black paint (SS-CuO) were fabricated, and investigated under Indian climatic conditions. The obtained results showed that the daily water productivity was enhanced by 11.8 % and 6.3 % for SS-rGO and SS-CuO, respectively in comparison to that of CSS. Moreover, the efficiency of the SS reached about 39.9 % for SS-rGO; while, it reached about 38.1 % and 35.7 % for the SS-CuO and CSS. Moreover, it is perceived that the proposed SS with rGO coated absorber has reduced 13.19 tons of CO2 emissions for 0.01 m water depth during its life cycle. In addition, quality of water samples achieved from experimental investigation is suitable for drinking purposes and also meets the requirements of the Indian Council of Medical Research.

description: The ethyl acetate and methanol extracts from aerial parts of Tanacetum balsamita yielded a new derivative of 1-acetyl-erivanin, namely 1-acetyl-3-epi-erivanin (17), some known compounds, namely seventeen sesquiterpene lactones, five flavonoids, four coumarins, and a steroid. All extracts displayed antibacterial activity against test microorganisms except for Escherichia coli. The methanol (TBM) extract with an IC50 value of 0.180 mg/mL exhibited good antioxidant activity against DPPH radical while all extracts showed significant anti-inflammatory activity against lipoxygenase enzyme. The ethyl acetate (TBEA) extract presented moderate activity against α-glucosidase enzyme with an IC50 of 0.808 mg/mL. The highest total phenol content with 91.050 mg GAE/g extract was found in TBM. It is the first study on the isolation of secondary metabolites as well as 5-lipoxygenase and α-glucosidase inhibitory activity of T. balsamita growing in Turkey.

description: Network traffic generators are invaluable tools that allow for applied experimentation to evaluate the performance of networks, infrastructure, and security controls, by modelling and simulating the communication packets and payloads that would be produced by machines and devices on the network. Specifically for security applications, these tools can be used to consistently simulate malicious activity on the network and test the components designed to detect and mitigate malicious activities, in a highly reliable and customisable way. However, despite the promising features, most of these tools have some problems that can undermine the correctness of experiments. The accuracy of the simulation results depends strongly on the performance and reliability of the used generator. Thus, in this paper, we investigate the performance and accuracy of three of the most reviewed network traffic generators in literature, namely Cisco TRex, Ostinato and Genesids. Mainly, the comparative experiments examine the strengths and limitations of these tools, which can help the research community to choose the most suitable one to assess the performance of their networks and security controls

description: We report the correction factors for centrifugal distortion in Raman intensities for pure rotation (O0- and S0-branch) and vibration–rotation (O1- and S1-branch) transitions in the ground electronic state of H2, HD and D2. These factors are presented for 52 selected excitation wavelengths and for the initial rotational states, J=2−21. This data is useful in applications of intensity calibration of spectrometers and the spectroscopy of flames. The classical treatment of centrifugal distortion involved the expansion of polarisability anisotropy (γ) over the internuclear distance, while assuming the diatomic molecule behaves as a harmonic oscillator. Here, this approximation of polarisability invariants as a Taylor series expansion is tested, revealing that truncation up to the second-order derivatives of mean polarisability (α¯) and polarisability anisotropy (γ) gives faithful representations, yielding accurate expectation values with error <0.2%, for the ground rovibrational state and for the fundamental transition.
An educational intervention to improve knowledge, attitude, and intention to use patient portals in people living with HIV
Creators: name: Thomas, Priscilla
Publisher: name: No Publisher Supplied
Year: 2019

description: Engagement in care is critical to achieving good health outcomes such as achieving viral suppression and managing comorbid conditions for people living with HIV (PLWH). Patient portals are emerging as a potential tool to increase patient engagement in care among PLWH by allowing access to personal health information and increasing patient and provider communication; however, adoption of patient portals remains low. Purpose: The purpose quality improvement project was to improve patients' knowledge, attitudes, and intentions to use patient portals.Methodology: This DNP quality improvement project used a pre-and-post-test one group design to assess the effectiveness of an educational intervention to improve participants' knowledge, attitudes, and intentions to use patient portals at an adult HIV support group. The pre-and-post-tests were developed using the Information-Motivation-Behavioral Skills Model. An educational intervention was conducted and a patient portal handout was distributed to participants. A question-and-answer period followed the intervention. Results: Four participants volunteered to participate in the project. All participants completed a demographic survey, pre-test, post-test, and evaluation survey. There was no significant difference in knowledge, attitudes, or intentions after the educational intervention. Conclusion: This project did not demonstrate an improvement in participants' knowledge, attitudes, or intentions to use patient portals through an educational intervention because participants were already using patient portals to engage in their care; however, participants indicated an increase in understanding about patient portals following the educational intervention. Patient portal use may allow patients to be more engaged in their care and have better communication with their providers. Engagement in care is critical to achieving good health outcomes such as achieving viral suppression and managing comorbid conditions for people living with HIV (PLWH). Patient portals are emerging as a potential tool to increase patient engagement in care among PLWH by allowing access to personal health information and increasing patient and provider communication; however, adoption of patient portals remains low.

In this article we report results obtained for single homogeneous and heterogeneous nanowires with a diameter smaller than 100 nm, for which we used CDI to retrieve information about deformation and faults existing in these wires. The article also discusses the influence of stacking faults, which can create artefacts during the reconstruction of the nanowire shape and deformation.

description: PURPOSEThis quality improvement project implemented the Stopping Elderly Accidents, Deaths & Injuries (STEADI) toolkit developed by the Centers for Disease Control and Prevention (CDC) into a primary care practice to screen older adults between the ages of 65 to 89 for fall risk. The objective was to screen at least 100 eligible patients for fall risk and implement appropriate interventions in at least 90% of those screened. METHODOLOGYInclusion criteria included individuals that were 65 to 89 years old and who were English speaking. Exclusion criteria included individuals with a history of dementia and those who had already participated in the project. In the office waiting room participants were asked to complete the Stay Independent brochure from the toolkit in order to categorize their level of fall risk and offer appropriate interventions accordingly which included educational brochures, proper footwear, and referrals to podiatry, ophthalmology, physical therapy and community exercise programs. A follow up survey was given to participants who returned to the office after the intervention. RESULTSFifty participants were screened for fall risk and appropriate interventions were implemented in 100% of those screened. Of these participants 26 were male and 24 were female. In total 24 were considered high risk for falls with a score of four or greater on the Stay Independent brochure and 26 were considered low risk with a score of less than four. Participants stated that the information provided increased their confidence in preventing falls.IMPLICATIONS FOR PRACTICEFindings from the project can be translated to primary care offices across the United States who wish to implement a fall prevention program. Future policy implications can include allocation of state funding to increase awareness and assistance in incorporating fall risk assessment into primary care practice.

description: In first part we have developed a simple regiocontrolled protocol of
1,3-DC to get ring fused pyrazole derivatives. These pyrazole derivatives were synthesized using
1,3-DC between nitrile imine and various dipolarophiles such as alkynes, cyclic α,β-ketones,
lactones, thiocatones and lactums. The reactions were found to be highly regiospecific.
In second part we have discussed about helicene, its properties, synthesis and applications
as asymmetric catalyst.Due to inherent chirality, herein we have made an
attempt to synthesize the helicene-thiourea based catalyst for asymmetric catalysis. The synthesis
involved formation of two key intermediates viz, bromo-phenanthrene 5 and a vinyl-naphthalene
10. The coupling of these two intermediates leads to formation of hexahelicene.
Psychosocial Development In College Students: A Cross-sectional Comparison between Athletes and Non-Athletes
Creators: name: Kohlstedt, Sarah Skopek
Publisher: name: American University
Year: 2023

description: Empirical research findings suggest that the college environment promotes intellectual advancement and occupational preparation, as well as the development of psychosocial strengths such as self-awareness, interpersonal skills, morality, and general health and well-being (Arnett, 2000; Pascarella & Terenzini, 2005). However, all students do not experience college in this same way, nor do they all reap the same benefits (King, 1994; Montgomery & Côté, 2003). For example, college student-athletes must manage the developmental challenges and stressors that all college students face, in addition to those imposed by the requirements and expectations of their athletic departments, coaches, teammates, and the NCAA. Although sport participation has the potential to promote the development of psychosocial skills (Potuto, 2007; Wright & Côté, 2003), evidence suggests that Division I intercollegiate athletic competition may interfere with students' adjustment to college (Downey, 2005), and with their transition out of college (Martens & Cox, 2000). Therefore, the purpose of this study was to examine differences in psychosocial development between varsity student-athletes (n = 235) and non-athlete students (n =154) enrolled at Division I universities; post-hoc, recreational student-athletes (n = 59) were included as a third comparison group. Male (n = 195) and female (n = 253) freshmen, sophomores, juniors, and seniors (N = 448) responded to measures of demographic information, psychosocial skills, athletic identity, parental and peer attachment, hyper-competitiveness, and depressive symptoms. MANOVA results indicated small to moderate, statistically significant differences in the reported psychosocial skills of varsity student-athletes, recreational student-athletes, and non-athlete students (F (12, 864) = 13.50, p < .001, η2 = .158). Specifically, compared to non-athlete students, recreational student-athletes reported greater problem-solving (F (2, 436) = 3.76, p = .024, η2 = .017); varsity and recreational student-athletes reported greater health maintenance (F (2, 436) = 44.76, p < .001, η2 = .170) and greater hyper-competitiveness (F (2, 436) = 15.09, p < .001, η2 = .065); and varsity and recreational student-athletes reported fewer depressive symptoms (F (2, 436) = 6.41, p = .002, η2 = .029). Findings are discussed in the context of participants' athletic identity, race, gender, and parental and peer attachment patterns. Theoretical approaches to college students' psychosocial development are also addressed.

Male (n = 195) and female (n = 253) freshmen, sophomores, juniors, and seniors (N = 448) responded to measures of demographic information, psychosocial skills, athletic identity, parental and peer attachment, hyper-competitiveness, and depressive symptoms. MANOVA results indicated small to moderate, statistically significant differences in the reported psychosocial skills of varsity student-athletes, recreational student-athletes, and non-athlete students (F (12, 864) = 13.50, p < .001, η2 = .158). Specifically, compared to non-athlete students, recreational student-athletes reported greater problem-solving (F (2, 436) = 3.76, p = .024, η2 = .017); varsity and recreational student-athletes reported greater health maintenance (F (2, 436) = 44.76, p < .001, η2 = .170) and greater hyper-competitiveness (F (2, 436) = 15.09, p < .001, η2 = .065); and varsity and recreational student-athletes reported fewer depressive symptoms (F (2, 436) = 6.41, p = .002, η2 = .029). Findings are discussed in the context of participants' athletic identity, race, gender, and parental and peer attachment patterns. Theoretical approaches to college students' psychosocial development are also addressed.

description: Using a one-dimensional $αω$-dynamo model appropriate to galaxies, we study the possibility of dynamo action driven by a stochastic alpha effect and shear. To determine the field evolution, one needs to examine a large number of different realizations of the stochastic component of $α$. The net growth or decay of the field depends not only on the dynamo parameters but also on the particular realization, the correlation time of the stochastic $α$ compared to turbulent diffusion timescale and the time over which the system is evolved. For dynamos where both a coherent and fluctuating $α$ are present, the stochasticity of $α$ can help alleviate catastrophic dynamo quenching, even in the absence of helicity fluxes. One can obtain final field strengths up to a fraction $\sim 0.01$ of the equipartition field $ B_{eq}$ for dynamo numbers $| D| \sim 40$, while fields comparable to $ B_{eq}$ require much larger degree of $α$ fluctuations or shear. This type of dynamo may be particularly useful for amplifying fields in the central regions of disk galaxies.

description: Abstract

Background: Caregivers of persons receiving hemodialysis require close and continuous assistance, as they face challenges in physical, emotional, psychological, social, and economic aspects, resulting in a significant caregiving burden. Methodology: This descriptive correlational study aimed to explore the caregivers burden and caregiving preparedness of caregivers for persons receiving hemodialysis, and to examine the relationship between caregiving preparedness and caregivers burden. A total of 144 caregivers were purposively selected from those providing care to persons receiving hemodialysis at Guangxi Hospital, People's Republic of China. Data were collected using questionnaires, which included a general information form of the caregivers, a caregiving preparedness assessment tool, and a caregiver burden assessment tool. Descriptive statistics and Spearman's correlation coefficient were used for data analysis. Results: The results revealed that caregivers experienced a relatively high caregiver burden (X̅ = 50.25, SD = 17.65). The caregiving burden in specific aspects were as follows: relationship burden (X̅ = 13.33, SD = 5.45), emotional burden (X̅ = 14.97, SD = 6.07), social and family life burden (X̅ = 7.67, SD = 4.37), financial burden (X̅ = 2.91, SD = 1.29), and loss of control over one’s own life (X̅ = 11.38, SD = 3.34). Caregiving preparedness was found to be low (X̅ = 14.21, SD = 5.24). Additionally, a moderate negative correlation was found between caregiving preparedness and overall caregiving burden (r = -0.474, p < 0.01). Moderate negative correlations were also found between caregiving preparedness and specific aspects of caregiving burden: relationship burden (r = -0.373, p < 0.01), emotional burden (r = -0.444, p < 0.01), social and family life burden (r = -0.430, p < 0.01), financial burden (r = -0.427, p < 0.01), and loss of control over one’s own life (r = -0.361, p < 0.01). Conclusion: This study provides fundamental information for nurses to better understand and prepare caregivers in order to reduce the caregiving burden for persons receiving hemodialysis.

description: The present study compared the interactions among Na +, K +, Mg2+ and Ca2+, thymine and its tautomers in the gas and solvent phase, an interaction dependent upon the electronic construction of the tautomers. Three types of cation interaction with thymine and its tautomers were observed. In the first one, the metal cations interacted with a lone pair of nitrogen or oxygen of the tautomers. In the second type, there was an interaction among the cations, nitrogen and oxygen at the same time; the last one was that of cations with the electron density of thymine π-system, where the cations were perpendicular to the ring of thymine. The interaction of metals cation with tautomers was studied in the gas and solvent phases; a comparison was then made between interactions in two phases. The interaction energy for all complexes indicated the stability of complexes, an energy which was higher in Ca2+ and Mg2+ compared with Na+ and K+. Concerning K+ and Na+, the stability of all complexes of tautomers was greater than that of thymine complexes; however, the stability of certain Ca2+ and Mg2+ complexes was lower than the complexes of thymine.

description: Surface waves process the turbulent disturbances which drive dynamics in many space, astrophysical and laboratory plasma systems, with the outer boundary of Earth's magnetosphere, the magnetopause, providing an accessible environment to study them. Like waves on water, magnetopause surface waves are thought to travel in the direction of the driving solar wind, hence a paradigm in global magnetospheric dynamics of tailward propagation has been well-established. Here we show through multi-spacecraft observations, global simulations, and analytic theory that the lowest-frequency impulsively-excited magnetopause surface waves, with standing structure along the terrestrial magnetic field, propagate against the flow outside the boundary. Across a wide local time range (09-15h) the waves' Poynting flux exactly balances the flow's advective effect, leading to no net energy flux and thus stationary structure across the field also. Further down the equatorial flanks, however, advection dominates hence the waves travel downtail, seeding fluctuations at the resonant frequency which subsequently grow in amplitude via the Kelvin-Helmholtz instability and couple to magnetospheric body waves. This global response, contrary to the accepted paradigm, has implications on radiation belt, ionospheric, and auroral dynamics and potential applications to other dynamical systems.

description: We present a first-principles study of bare and hydrogen passivated armchair nanoribbons of the puckered single layer honeycomb structures of silicon and germanium. Our study includes optimization of atomic structure, stability analysis based on the calculation of phonon dispersions, electronic structure and the variation of band gap with the width of the ribbon. The band gaps of silicon and germanium nanoribbons exhibit family behavior similar to those of graphene nanoribbons. The edges of bare nanoribbons are sharply reconstructed, which can be eliminated by the hydrogen termination of dangling bonds at the edges. Periodic modulation of the nanoribbon width results in a superlattice structure which can act as a multiple quantum wells. Specific electronic states are confined in these wells. Confinement trends are qualitatively explained by including the effects of the interface. In order to investigate wide and long superlattice structures we also performed empirical tight binding calculations with parameters determined from \textit{ab initio} calculations.

description: In this study, it is shown that in a layered nitride superconductor, i.e., LixZrNCl (0.07<=x<=0.21), the superconducting order parameter is highly anisotropic in a sample with x=0.12, as inferred from both the temperature and the magnetic field dependences of the muon depolarization rate (sigma_s, proportional to the superfluid density). Moreover, the tendency of strong anisotropy with an increase in x is indicated by the T dependence of sigma_s. These observations are in good agreement with the recent theory that predicts the development of anisotropy in a d+id' gap upon carrier filling to the bands with disconnected Fermi surfaces on a honeycomb lattice.

description: Recently a large interest has arisen for using less active reducers of graphene oxide, GO, that are friendly with the environment. In the present work, a DFT theoretical study on the reduction process of GO model surfaces is performed taking into account zwitterionic dopamine, ZDA, as reducing agent. Several periodic models representing epoxy and hydroxyl patches on GO basal plane are proposed. As the number of oxide groups in a patch of epoxies or hydroxyls on the surface of graphene increases from 1 to 5, these systems become more stable. Whereas the adsorption of ZDA on patches of GO with 5 epoxy groups is non-dissociative, that of ZDA on patches of GO with 5 hydroxyl groups is fundamentally dissociative, reducing the surface of graphene oxide. The H2O molecule produced in the GO reduction becomes trapped to ZDA through a hydrogen bond. The ZDA binding to GO was analysed by considering electrostatic effects and attractive non-covalent contributions due to vdW interactions.

description: [ABRIDGED] We study supermassive black hole binary mergers driven by angular momentum loss to small-scale gas discs. Such binaries form after major galaxy mergers, but their fate is unclear since hardening through stellar scattering becomes very inefficient at sub-parsec distances. Gas discs may dominate binary dynamics on these scales, and promote mergers. Using numerical simulations, we investigate the evolution of the orbits of binaries embedded within geometrically thin gas discs. Our simulations directly resolve angular momentum transport within the disc, which at the radii of interest is likely dominated by disc self-gravity. We show that the binary decays at a rate which is in good agreement with analytical estimates, while the eccentricity grows. Saturation of eccentricity growth is not observed up to values e > 0.35. Accretion onto the black holes is variable, and is roughly modulated by the binary orbital frequency. Scaling our results, we analytically estimate the maximum rate of binary decay that is possible without fragmentation occuring within the surrounding gas disc, and compare that rate to an estimate of the stellar dynamical hardening rate. For binary masses in the range 10^5 < M/Msun < 10^8 we find that decay due to gas discs may dominate for separations below a ~ 0.01--0.1 pc, where the disc is optically thick. The minimum merger time scale is shorter than the Hubble time for M < 10^7 Msun. This implies that gas discs could commonly attend relatively low mass black hole mergers, and that a significant population of binaries might exist at separations of a few hundredths of a pc, where the combined decay rate is slowest. For more massive binaries, we suggest that scattering of stars formed within a fragmenting gas disc could act as a significant additional sink of binary angular momentum.
