title: Educating the Dietitian on Nutritional Counseling Principles in Diabetes Mellitus and their Application for Adolescents with Insulin-Dependent Diabetes: Use of a Learning Package
Creators: name: DeLeeuw, Eileen R.
Publisher: name: Utah State University
Year: 1981

description: The purpose of this study was to develop and test a Learning Package on nutritional counseling principles in diabetes mellitus with specific application for adolescents with insulin-dependent diabetes. The Learning Package was designed to be used as continuing education material for the clinical dietitian. It consisted of two audio tapes, 2 1/2 hours in length, recorded by the author and an accompanying handbook or resourcebook. The resourcebook materials were designed to give further details, provide resources and materials for future reference, visually reinforce the audio presentation, summarize information given in the presentation, and give a bibliography of the references cited. The presentation was divided into four sections: Guidelines for Education of Individuals with Diabetes Mellitus; Educational Program Planning in a Health Care Agency; The Adolescent with Insulin-Dependent Diabetes; The Educator-Client Interaction.
Following initial formative evaluations, the Learning Package was field tested in a seminar for practicing clinical dietitians held in three locations with several subjects completing the test in the home setting. Pre and posttest scores and attitudes of the participants towards the Guidelines and Learning Package were collected and are reported. Suggestions for improvement of the Learning Package and demographic data were also collected and are reported. Only 13.8% of the subjects met the 90% criterion as determined on the posttest. There was improvement from both forms of the pretests to the posttest. Tests of statistical significance were not conducted. Participants indicated acceptance of the Learning Package as a continuing education tool and of the Guidelines as of practical value to them in their practices.
Recommendations are made for improvement and revision of the Learning Package and final (summative) evaluation and testing before packaging and distribution by the American Dietetic Association. It is concluded that the Learning Package is acceptable to practitioners and, with the suggested revisions, can meet the continuing education needs of dietitians to improve nutritional education of persons with diabetes, as identified in the literature.

description: We report results of large-scale molecular-dynamics (MD) simulations of dynamic deformation under biaxial tensile strain of pre-strained single-crystalline nanometer-scale-thick face-centered cubic (fcc) copper films. Our results show that stacking faults, which are abundantly present in fcc metals, may play a significant role in the dissociation, cross-slip, and eventual annihilation of dislocations in small-volume structures of fcc metals. The underlying mechanisms are mediated by interactions within and between extended dislocations that lead to annihilation of Shockley partial dislocations or formation of perfect dislocations. Our findings demonstrate dislocation starvation in small-volume structures with ultra-thin film geometry, governed by a mechanism other than dislocation escape to free surfaces, and underline the significant role of geometry in determining the mechanical response of metallic small-volume structures.

description: What do you think of when you hear the word RAID? Johnny Depp style pirates battling it out on the high seas? RAIDing the refrigerator Nigella Lawson style? Spraying a can of RAID on some pesky biting bugs? Whatever it is, it infers you will be “doing” something. RAID in the identifier world applies best to “doing” things. It’s an identifier that puts research projects at the centre of the research world. At its core, RAID is a Handle which acts like a web address for a project or group of activities, and it comes with an “envelope” which contains a record of events and entities related to the project or activity. Examples of things that are related to a project include Data Management Plans, research publications, datasets, researchers, institutions, grants etc. RAID can record all of these related entities in the envelope using their appropriate PIDs (DOIs, ORCIDs etc). There is significant interest in RAID internationally and in this session, we will unpack RAID and answer such questions as: What are the use cases for RAID? Who benefits from RAID? What’s the difference between a Grant Identifier (DOI) and a RAID? Do you need both? Who manages RAID and how many are using it? How does RAID interact with ORCIDs, DOIs and other identifiers? How is RAID being used in the research Openness Profile? What are the plans for the RAID identifier service going forward in terms of technical, governance and community aspects? RAID is flagged for ISO certification in May 2021. This is an opportunity to hear more about RAID and how you may wish to use it.
Carbonate Platform Growth and Cyclicity at a Terminal Proterozoic Passive Margin, Infra Krol Formation and Krol Group, Lesser Himalaya, India

description: The Infra Krol Formation and overlying Krol Group constitute a thick (less than 2 km), carbonate-rich succession of terminal Proterozoic age that crops out in a series of doubly plunging synclines in the Lesser Himalaya of northern India. The rocks include 18 carbonate and siliciclastic facies, which are grouped into eight facies associations: (1) deep subtidal; (2) shallow subtidal; (3) sand shoal; (4) peritidal carbonate complex; (5) lagoonal; (6) peritidal siliciclastic–carbonate; (7) incised valley fill; and (8) karstic fill. The stromatolite-rich, peritidal complex appears to have occupied a location seaward of a broad lagoon, an arrangement reminiscent of many Phanerozoic and Proterozoic platforms. Growth of this complex was accretionary to progradational, in response to changes in siliciclastic influx from the south-eastern side of the lagoon. Metre-scale cycles tend to be laterally discontinuous, and are interpreted as mainly autogenic. Variations in the number of both sets of cycles and component metre-scale cycles across the platform may result from differential subsidence of the interpreted passive margin. Apparently non-cyclic intervals with shallow-water features may indicate facies migration that was limited compared with the dimensions of facies belts. Correlation of these facies associations in a sequence stratigraphic framework suggests that the Infra Krol Formation and Krol Group represent a north- to north-west-facing platform with a morphology that evolved from a siliciclastic ramp, to carbonate ramp, to peritidal rimmed shelf and, finally, to open shelf. This interpretation differs significantly from the published scheme of a basin centred on the Lesser Himalaya, with virtually the entire Infra Krol–Krol succession representing sedimentation in a persistent tidal-flat environment. This study provides a detailed Neoproterozoic depositional history of northern India from rift basin to passive margin, and predicts that genetically related Neoproterozoic deposits, if they are present in the High Himalaya, are composed mainly of slope/basinal facies characterized by fine-grained siliciclastic and detrital carbonate rocks, lithologically different from those of the Lesser Himalaya.

Subjects: analog signal processing

description: The LWA (Long-Wavelength Array), located at Owens Valley Radio Observatory, is a powerful and sensitive radio telescope. OVRO-LWA needs very good signal transmission with minimal spurious emissions carried through its signal chain. The telescope receives analog radio signals from space, then interprets them as digital data that can be computationally analyzed to gain a better understanding of what that data means. In order to minimize unwanted effects, some parts of the signal chain are being redesigned. This includes possible changes in the ADCs employed, the FPGA used, or the circuitry linking the two. A variety of options are available for the new hardware, including several boards from the CASPER1 collaboration. Currently, the LWA uses CASPER ADC16x250-8 RJ45 rev 1 boards with HMCAD1511 ADC chips. A different CASPER board, or a new combination of ADC and FPGA hardware from multiple platforms, may be used. Among the candidate replacement boards is SNAP2 (Smart Network ADC Processor). In order to determine the viability of retooling the SNAP board for this purpose, the performance characteristics of its ADC hardware have been tested.

Fostering ethical competence in managerial leadership : a eudaimonistic perspective
Creators: name: Flynn, Robert Frederick
Publisher: name: University Of Tasmania
Year: 2023

description: Since the late 1980s the need for improved ethical sensibility, on the part of those in managerial leadership roles, has been widely recognised throughout Australian society. Unfortunately, while the hortatory nature of the discourse has been both loud and consistent, what has been lacking is any firm set of guidelines on how to bring about the necessary improvement. The argument presented in this essay represents one attempt to address that shortcoming. In particular, I will show that a discipline I call critical eudaimonistic - reflection can play a pivotal role in cultivating the sort of deliberate character needed to underwrite ethically competent leadership practice. I begin by establishing firm ground on which to postulate a robust conceptualisation of managerial leadership. In doing this, I identify the notions of trust and community as pivotal themes. Specifically, I show that an ability to build and maintain a high-trust community lies at the core of what effective managerial leadership is all about. Moreover, as trust and community are concepts rich in ethical implication, I show how a meaningful conceptualisation of ethical competence can be built around them. By way of addressing the challenge posed by the mythical figure of the hard-nosed decision-maker (the budget-conscious senior corporate executive holding the authority to commission leadership development programmes), I argue for learning to work within the prevailing corporate idiom. This includes ensuring adherence to the correct vernacular, and also the selection and adoption of suitable conceptual models. I show how one particular model of strategic change planning can be successfully employed to re-cast the development challenge in a manner that not only guarantees idiomatic compliance, but that also ensures that consideration is given to the relevant variables. One such variable consists in the need for a robust syllabus structure. I argue that when human character is the developmental focal point, the syllabus can be appropriately built on a virtue ethics platform. More specifically, I argue for adoption of one particular neo-Aristotelian expression of the ancient doctrine of eudaimonism. I go further to show how the syllabus content can be shaped so as to expedite the acquisition of competence in critical eudaimonistic reflection. I finish with the claim that neither recognition of the need for a development programme aimed at character cultivation, nor availability of a robust syllabus, will of themselves guarantee enthusiastic participation in such a project. To achieve that, in the Australian corporate context, I argue that one must be capable of overcoming the perception that the subject matter is too vague and esoteric. I address this by describing a strategy, currently being employed, with some success, a number of test sites. I close off by suggesting some ways in which it can be improved in light of lessons learned to date.
title: Teacher Perceptions of Factors Influencing Technology Integration in K-12 Schools
Creators: name: Ames, Clarence W.M.
Publisher: name: Utah State University
Year: 2017

description: The purpose of this case study was to examine teachers’ perceptions of what factors are most influential to the successful integration of technology. In the Junior High with the highest technology usage in a preexisting statewide technology initiative, data were collected from six teachers and one administrator through interviews and observations. Teachers primarily highlighted factors related to support and product functionality as influential. This study also examines factors such as change management, learning environment, and student motivation to understand the relationship of these factors to teacher perceptions of factors that influence technology integration. Though many influential factors emerged that all seemed highly interrelated, the most common theme that emerged across all factors was that letting teachers show each other how to use the technology to make life easier and improve learning for students may result in higher levels of technology integration.

description: Recent studies of terminal Neoproterozoic rocks (ca. 590–543 Ma) in the Lesser Himalaya of northwestern India and the Yangtze block (south China) reveal remarkably similar facies assemblages and carbonate platform architecture, with distinctive karstic unconformities at comparable stratigraphic levels. These similarities suggest that south China may have been located close to northwestern India during late Neoproterozoic time, an interpretation permitted by the available, yet sparse paleomagnetic data. Additional parallels in older rocks of both blocks—similar rift-related siliciclastic-volcanic successions overlying metamorphic basement, and comparable glaciogenic intervals of possibly Sturtian and Marinoan or Varanger age—suggest that this spatial relationship may have developed earlier in the Neoproterozoic. With the exception of basal Cambrian phosphorite and comparable small shelly fossils, stratigraphic contrasts between northern India and south China and increasing biogeographic affinity between south China and northwestern Australia suggest that south China may have migrated toward northwestern Australia during the Cambrian.

description: We study the typical entanglement properties of a system comprising two independent qubit environments interacting via a shuttling ancilla. The initial preparation of the environments is modeled using random-matrix techniques. The entanglement measure used in our study is then averaged over many histories of randomly prepared environmental states. Under a Heisenberg interaction model, the average entanglement between the ancilla and one of the environments remains constant, regardless of the preparation of the latter and the details of the interaction. We also show that, upon suitable kinematic and dynamical changes in the ancilla-environment subsystems, the entanglement-sharing structure undergoes abrupt modifications associated with a change in the multipartite entanglement class of the overall system's state. These results are invariant with respect to the randomized initial state of the environments.

Movement and drama with mentally retarded children in the United Kingdom : a survey of recent literature and current practices
Creators: name: Hale, JA
Publisher: name: University Of Tasmania
Year: 2023

description: In Part One the definition of mental retardation, as formulated by the American Association on Mental Deficiency, is adopted and examined in relation to the needs of mentally retarded children. The definition is seen as useful in that it emphasises current adaptive behaviour, avoids etiological considerations, and sees prognosis as a function of associated conditions together with treatment and training opportunities. The child's view of himself vis'a-vis the world at large is discussed, particularly as it relates to his and society's expectations. In developing the discussion it becomes imperative to analyse those concepts which appear to describe the child's mental, physical and emotional states and which are thought of as motivating his behaviour. Such concepts include the selfconcept and self-esteem; failure and success as personally felt and socially observed phenomena; emotional security, displacement, competence and effectance; sensitivity to external cues and a generalised defensiveness; imagination and creativity. Part Two investigates the expressive arts in general and drama and movement in particular for the mentally retarded child; their place in his life and right and as a therapeutic mode. There follows a comparison of proposals and techniques (and their underlying rationale) for drama and movement as advocated by some important teachers and writers, and those they have influenced. Movement as the common denominator of all human activity is discussed and, in conjunction with drama, is offered as establishing and supporting a sense of valuable identity. The relationship between the capacity for emotional experience and the opportunity for such experience is probed; earned success emerges, from the writers' views, as a corner-stone for the strengthening of self-esteem and the consolidation of emotional security. A description of a selection of practical movement and drama sessions in which the present writer has been involved forms Part Three of this study. Work described includes one-to-one foundation movement with severely subnormal children (SSN); movement with autistic children; group role-play with SSN children; free drama and one-role sessions with moderately subnormal children (ESNM).
title: Participation in Dual Language Immersion Programs: Using Theory of Planned Behavior to Predict Enrollment
Creators: name: Call, Andrea
Publisher: name: Utah State University
Year: 2017

description: Ajzen’s theory of planned behavior (TPB) has been used to help predict and explain human behavior in specific situations. According to the TPB model, behavior is based on behavioral intention and the three determinants to behavioral intention include attitudes, subjective norms and perceived behavioral control. According to TPB, perceived behavioral control moderates the effect of behavioral intentions on behavior. Previous research has focused on the application of TPB to health behaviors, although some research has been done in educational situations. In addition, dual language immersion (DLI) programs are increasing in popularity, particularly in Utah. The Utah model begins in first grade, and follows a 50/50 model. Because of its researched based program, Utah has become a recognized leader in the field of DLI through its focus on sufficient instruction time, active cognitive engagement, motivation, continuity of learning, and cultural interaction. However, little is known about the factors that motivate parents to enroll their children in DLI. The current study uses longitudinal survey methodology to evaluate how the TPB applies to parents’ intentions and behavior of enrollment in DLI (N = 74). Approximately one third of participants took steps towards enrollment. Results indicate that parental attitudes significantly influenced behavioral intentions to enroll. In addition, for every one-unit increase in behavioral intentions, there was a 2.78 greater likelihood in enrollment. Limitations of sample size and difficulties of recruitment are discussed. Implications of the findings and areas for future research are also presented.
Warp and eccentricity propagation in discs around black holes

description: We consider the inward propagation of warping and eccentric disturbances in discs around black holes under a wide variety of conditions. In our calculations we use secular theories of warped and eccentric discs and assume the deformations to be stationary and propagating in a disc model similar to regions (a) and (b) of Shakura and Sunyaev discs. We find that the propagation of deformations to the innermost regions of the disc is facilitated for low viscous damping and high accretion rate. We relate our results to the possible excitation of trapped inertial modes, and to the observations of high-frequency quasi-periodic oscillations (QPOs) in black hole systems in the very high spectral state.

title: The Effect of Heat Treatment on Meat Heme and Nonheme Iron Bioavailability for the Anemic Rat
Creators: name: Jansuittivechakul, Oranong
Publisher: name: Utah State University
Year: 1983

description: Three separate experiments were conducted to investigate the effects of heat treatment on meat heme and nonheme iron bioavailability in anemic rats. Male weanling Sprague-Drawley rats were first made anemic, then subsequently fed with experimental diets. In the first experiment, dietary iron sources were raw or autoclaved meat mixed with ferrous sulfate to give the ratios of iron from meat and ferrous sulfate equal to 100:0, 75:25, 50:50, 25:75, and 0:100 respectively. For the second experiment, the dietary iron sources were raw or autoclaved meat mixed with bovine hemoglobin (HB) to give dietary iron ratios as described for experiment 1. For experiment 3, dietary iron sources were boiled meat and baked meat.
Known amounts of the experimental diets were fed the anemic rats for a 10-day repletion period. Body weight, hemoglobin concentration and hematocrit were determined before and after the repletion period. The animals were then sacrificed and the liver iron content was measured, as was the iron content of the feces from the last 7 days on test of each rat. In vitro digestion was done to determine the amount of soluble iron in the diets.
Heat treatment increased the bioavailability of iron from hemoglobin from 23% to 30%. The effect of cooking on the bioavailability of iron from meat and ferrous sulfate were negligible. The efficiencies of conversion were 35, 37, 36 and 37 for raw meat, autoclaved meat, boiled meat and baked meat, respectively. Ferrous sulfate gave the highest bioavailability in anemic rats (65%). As the dietary proportion of iron from ferrous sulfate increased, the dietary iron bioavailability increased proportionally. Iron bioavailability decreased as the proportion of dietary iron from hemoglobin (HB) increased. Meat did not increase the bioavailability of iron from either ferrous sulfate or hemoglobin.
Heat treatment decreased the heme iron content in the diets but did not affect the amount of soluble iron. Soluble iron content increased as the dietary proportion of iron from ferrous sulfate or hemoglobin (HB) increased. There was no correlation between the iron. bioavailability in rat and the soluble iron content determined by in vitro digestion.
Kinematic Evidence for Downdip Movement on the Mormon Peak Detachment

description: The Mormon Peak detachment is considered to be one of the best examples of a rooted upper crustal detachment fault that propagated through the brittle crust at a low angle. The hanging wall of the detachment today consists of a number of isolated blocks that have been interpreted as remnants of a once-contiguous extensional allochthon. Here we present the results of a new study of directional indicators from the basal surfaces beneath these blocks. These measurements do not agree with the long-standing interpretation of a S75°W movement direction for the detachment hanging wall. Instead, the most recent movement on each section of the detachment took place approximately parallel to the present downdip direction. We conclude that the Mormon Peak detachment is best explained as the basal surfaces to a series of rootless gravity slides.

description: We compare the detection abilities for the relic gravitational waves by two kinds of forthcoming cosmic microwave background radiation (CMB) experiments, space-based Planck satellite and the various ground-based experiments. Comparing with the ground-based experiments, Planck satellite can observe all the CMB power spectra in all the multipole range, but having much larger instrumental noises. We find that, for the uncertainty of the tensor-to-scalar ratio $Δr$, PolarBear (II) as a typical ground-based experiment can give much smaller value than Planck satellite. However, for the uncertainty of the spectral index $Δn_t$, Planck can give the similar result with PolarBear (II). If combining these two experiments, the value of $Δn_t$ can be reduced by a factor 2. For the model with $r=0.1$, the constraint $Δn_t=0.10$ is expected to be achieved, which provides an excellent opportunity to study the physics in the very early universe. We also find the observation in the largest scale ($\ell<20$) is very important for constraining the spectral index $n_t$. So it is necessary to combine the observations of the future space-based and ground-based CMB experiments to determine the relic gravitational waves.

Creators: name: Fan, Paul Hwaleun
Publisher: name: Utah State University
Year: 1981

description: An affinity column for cathepsin D was prepared making use of the strong affinity of pepstatin for cathepsin D. Pepstatin is an N-acylated pentapeptide from Actinomycetes with the following structure: isovaleryl-L-valyl-L-valyl-4-amino-3-hydroxy-6-methylheptanoyl-L-alanyl-4-amino-3-hydroxy- 6-methyl heptanoic acid. A relatively rapid and efficient method for cathepsin D purification has been developed; Steps include homogenization, ammonium sulfate fractionation, and chromatography on pepstatin-Sepharose column. The final preparation has a specific activity of 38 units/mg. and shows a single protein band on polyacrylamide gel electrophoresis in sodium dodecyl sulfate corresponding to a subunit molecular weight of 42,000. Polyacrylamide gel electrophoresis studies did not reveal any impurities. The proteolytic activity of isolated cathepsin D on bovine myofibrils and myosin was examined at pH 3.80, 37 °C. The heavy chains of myosin, as well as other smaller regulatory proteins of the myofibrils were degraded. Actin was degraded less rapidly than myosin heavy chain. Degradation became more extensive when the substrate-enzyme incubation time was increased.

description: We describe a comprehensive pulsar monitoring campaign for the Large Area Telescope (LAT) on the {\em Fermi Gamma-ray Space Telescope} (formerly GLAST). The detection and study of pulsars in gamma rays give insights into the populations of neutron stars and supernova rates in the Galaxy, into particle acceleration mechanisms in neutron star magnetospheres, and into the "engines" driving pulsar wind nebulae. LAT's unprecedented sensitivity between 20 MeV and 300 GeV together with its 2.4 sr field-of-view makes detection of many gamma-ray pulsars likely, justifying the monitoring of over two hundred pulsars with large spin-down powers. To search for gamma-ray pulsations from most of these pulsars requires a set of phase-connected timing solutions spanning a year or more to properly align the sparse photon arrival times. We describe the choice of pulsars and the instruments involved in the campaign. Attention is paid to verifications of the LAT pulsar software, using for example giant radio pulses from the Crab and from PSR B1937+21 recorded at Nançay, and using X-ray data on PSR J0218+4232 from XMM-Newton. We demonstrate accuracy of the pulsar phase calculations at the microsecond level.

description: On a hemispheric scale, it is now well established that stratospheric ozone depletion has been the principal driver of externally forced atmospheric circulation changes south of the Equator in the last decades of the 20th Century. The impact of ozone depletion has been felt over the entire hemisphere, as reflected in the poleward drift of the midlatitude jet, the southward expansion of the summertime Hadley cell and accompanying precipitation trends deep into the subtropics. On a regional scale, however, surface impacts directly attributable to ozone depletion have yet to be identified. In this paper we focus on South Eastern South America (SESA), a region that has exhibited one of the largest wetting trends during the 20th Century. We study the impact of ozone depletion on SESA precipitation using output from 6 different climate models, spanning a wide range of complexity. In all cases we contrast pairs of model integrations with and without ozone depletion, but with all other forcings identically specified. This allows for unambiguous attribution of the computed precipitation trends. All 6 climate models consistently reveal that stratospheric ozone depletion results in a significant wetting of SESA over the period 1960–1999. Taken as a whole, these model results strongly suggest that the impact of ozone depletion on SESA precipitation has been as large as, and quite possibly larger than, the one caused by increasing greenhouse gases over the same period.

As repletion or curative assay techniques form the central body of investigative research in iron utilization, the first subject of inquiry was the effect of repletion interval and degree of depletion upon the animals as monitored by physical indicators such as blood volume, growth and hematinic response. Percent blood volume is a particularly useful figure in the calculation of the amount of hemoglobin iron but was found to be relatively constant in a preliminary experiment. Accordingly, the effects of growth and anemia on hemoglobin response and blood volume were examined in 122 weanling male rats which had been depleted for seven days by low iron diet and phlebotomy, then repleted by feeding iron rich diet (47.1 ppm) for zero, five, 10 and 15 days. Percent blood volume proved to be rather constant at 7.5 in these pre-pubescent animals. The most severely depleted animals appeared to regenerate hemoglobin initially rather than replenish tissue iron.
Regeneration Efficiency and AOAC assay methods were compared in a study involving the relative potency of two iron salts, ferrous sulfate and ferric orthophosphate, and three commercial cereal sources containing electrolytically reduced, hydrogen reduced or ferric orthophosphate supplements. These two assays utilized 202 albino male weanling rats. The superior availability of ferrous sulfate was evident in both regeneration efficiency and AOAC assays, as was the relative similarity of the dietary iron sources, yet the commercial sources in general provided more available iron in comparison to the reference ferrous sulfate than expected, possibly due to the influence of dietary components and processing variables. Bioavailability based on dietary iron concentration response correlated highly (r = 0.94) between animal groups analyzed using the Regeneration Efficiency and AOAC methods. Stress may have been a factor in animals assayed by the AOAC technique which used a 28 day depletion interval followed by a two week repletion. The Regeneration Efficiency method, which utilizes shorter depletion and repletion intervals also offered sufficient amounts of dietary iron for normal growth. The calculation of iron bioavailability also is dependent on such pertinent variables as dietary intake amount, body weight gain and percent blood volume.

description: This paper considers a partitioned population and develops a decomposition of the Gini index in two components, which measure the within and the between groups inequality. Differently from the most widespread inequality measure decompositions, having a between component that compares the means of the groups, ours informs about the distance between their entire distributions. This makes the decomposition helpful in several frameworks, such as in the measurement of spatial concentration A Monte Carlo experiment supports the appropriateness of our components highlighting that they strongly correlate with two axiomatically derived benchmarks. The presentation of a case study concerning the income distribution in the Italian provinces concludes the work and stresses the informativeness of the proposed decomposition.

description: Within a landscape, a species’ occurrence is dictated by the availability of suitable habitat and resources needed for survival; however, occurrence is not only affected by the characteristics of occupied sites, but also by the characteristics of the surrounding landscape. The endangered Blanding’s turtle (Emydoidea blandingii), a semi-aquatic freshwater turtle, occupies a wide range of wetlands and landscapes in southeastern Canada and the northeastern United States. While the effects of habitat characteristics on wetland occupancy by Blanding’s turtles have been documented, here I explore whether the probability of wetland occupancy by Blanding’s turtles is affected by the surrounding landscape. I used visual surveys, environmental DNA, and atlas data to document the presence of Blanding’s turtles. I then used boosted regression tree modelling to determine how landscape composition explains wetland occupancy. Forest cover around the surveyed wetlands was the strongest positive driver of turtle occupancy while anthropogenic land cover was the strongest negative driver of turtle occupancy. Generally, human disturbances in a landscape lowered the probability of occupancy. Overall, I determined that wetland occupancy by Blanding’s turtles is affected by landscape composition and that, therefore, wetland occupancy can successfully be predicted from the composition of the surrounding landscape.

description: We study how single-crystal chromium films of uniform thickness on W(110) substrates are converted to arrays of three-dimensional (3D) Cr islands during annealing. We use low-energy electron microscopy (LEEM) to directly observe a kinetic pathway that produces trenches that expose the wetting layer. Adjacent film steps move simultaneously uphill and downhill relative to the staircase of atomic steps on the substrate. This step motion thickens the film regions where steps advance. Where film steps retract, the film thins, eventually exposing the stable wetting layer. Since our analysis shows that thick Cr films have a lattice constant close to bulk Cr, we propose that surface and interface stress provide a possible driving force for the observed morphological instability. Atomistic simulations and analytic elastic models show that surface and interface stress can cause a dependence of film energy on thickness that leads to an instability to simultaneous thinning and thickening. We observe that de-wetting is also initiated at bunches of substrate steps in two other systems, Ag/W(110) and Ag/Ru(0001). We additionally describe how Cr films are converted into patterns of unidirectional stripes as the trenches that expose the wetting layer lengthen along the W[001] direction. Finally, we observe how 3D Cr islands form directly during film growth at elevated temperature. The Cr mesas (wedges) form as Cr film steps advance down the staircase of substrate steps, another example of the critical role that substrate steps play in 3D island formation.

Streamflow--Analysis
Water resources development--Management

description: Temperatures in semiarid Mongolia have rapidly risen over the past few decades, and increases in drought, urban development, mining, and agriculture have intensified demands on limited water resources. Understanding long-term streamflow variation is critical for Mongolia, particularly if alterations in streamflow are being considered and because of the potential negative impacts of drought on the animal agriculture sector. Here, we present a temporally and spatially improved streamflow reconstruction for the Kherlen River. We have added 11 new records in comparison with two in the original 2001 reconstruction. This new reconstruction extends from 1630 to 2007 and places the most recent droughts in a multicentennial perspective. We find that variations in streamflow have been much greater in the past than in the original study. There was higher variability in the mid to late 1700s, ranging from severe and extended drought conditions from 1723 to 1739 and again in 1768–1778 to two decadal length episodes of very wet conditions in the mid 1700s and late 1700s. Reduced amplitude is seen in the mid-1800s, and several pluvial events are reconstructed for the 1900s. Although recent droughts are severe and disturbing economic and ecological systems in Mongolia and it appears that eastern Mongolia is drying, the drying trend since the late 1900s might in fact be accentuated by a change from a particularly wet era in Mongolia. The recent drought might be a return to more characteristic hydroclimatic conditions of the past four centuries in Mongolia.

description: In this paper, we consider a rotating heavy quark-antiquark ($q\bar{q}$) pair in a ${\mathcal{N}}$=4 SYM thermal plasma. We assume that $q\bar{q}$ center of mass moves at the speed $v$ and furthermore they rotate around the center of mass. We use the AdS/CFT correspondence and consider the effect of external electromagnetic field on the motion of the rotating meson. Then we calculate the jet-quenching parameter corresponding to the rotating meson in the constant electric field.
