description: We investigate the interplay between the non-Hermiticity and finite temperature in the context of mixed state dynamical quantum phase transition (MSDQPT). We consider a $p$-wave superconductor model, encompassing complex hopping and non-Hermiticity that can lead to gapless phases in addition to gapped phases, to examine the MSDQPT and winding number via the intra-phase quench. We find that the MSDQPT is always present irrespective of the gap structure of the underlying phase, however, the profile of Fisher zeros changes between the above phases. Such occurrences of MSDQPT are in contrast to the zero-temperature case where DQPT does not take place for the gapped phase. Surprisingly, the half-integer jumps in winding number at zero-temperature are washed away for finite temperature in the gapless phase. We study the evolution of the minimum time required by the system to experience MSDQPT with the inverse temperature such that gapped and gapless phases can be differentiated. Our study indicates that the minimum time shows monotonic (non-monotonic) behavior for the gapped (gapless) phase.

title: Effect of Drilling Fluid Components and Mixtures on Plants and Soils
Creators: name: Honarvar, Shahnaz
Publisher: name: Utah State University
Year: 1975

description: Using greenhouse pot techniques, 32 drilling mud components were tested to see if, at a high rate of addition, they reduced plant growth. Green beans and sweet corn were the test plants. The excellent black, silt loam, slightly acidic, uncultivated Dagor soil (Cumulic Haploxeroll) was used for most tests. Rates used were considered to be abnormal level (high rate) and usual (low rate) amounts that might be added in commonly used drilling muds.
Drilling mud components that caused no observable or statistically significant reductions of plant yield are the following: Super Visbestos, (Asbestos), asphalt, Ben-Ex (a vinyl acetate and maleic anhydride copolymer), bentonite, Cypan (sodium polyacrylate), DME (ethoxylated nonyl phenol), Super Lube Flow (gilsonite), paraformaldehyde, Separan-AP- 273 (Dow-made, Shell-supplied polymer), sodium acid pyrophosphate, and sodium carboxymethyl cellulose.
Drilling mud components that barely caused a statistical significant (5 percent level) reduction in yield for only one of the two plant species when added to the soil only and, therefore, is of questionable hazard to plant growth are the following: Barite (BaSO4), Desco (modified tannin), Drillaid 412 (a filming amine), Drillaid 405 (diesel oil replacement), Kelzan-XC (a xanthan gum), Pipe dope, Lingo (lignite), Soltex (sulfonated asphalt?), and Witconnate 1840 (sulfonated tall oil).
Drilling mud components causing significant reduction in plant growth mostly at only the high addition rates to soil-mud mixtures are the following: Desco (modified tannin?), Dextrid (a non-fermenting starch), pregelatinized starch, Q-Broxin (an iron chromelignosulfonate), Gendril Thik (guar gum), and Kwik-Seal.
The most severe reductions in plant growth were caused by the following materials: Sodium hydroxide at the high rate (which was used in the soil-mud mixture with calcium lignosulfonate and with lignite), diesel oil and potassium chloride at both rates. The latter salt completely inhibited plant germination.
Probable causes for plant growth reductions, photographic and visual records, and a discussion of the results is presented in some detail.
Structure and deformation characteristics of beta'AuZn
Creators: name: Causey, Allan Robert
Publisher: name: University of British Columbia
Year: 2011

description: The deformation behaviour of the intermetallic CsCl-structure compound β'AuZn has been investigated over a wide range of metallurgical variables. The plastic deformation, specifically the stress-strain relation, has been characterized in terms of the effects of composition, temperature, strain-rate, and grain size. The constitutional defect structure was investigated using lattice parameter measurements and annealing experiments. Polycrystalline AuZn was found to behave in a ductile manner, over the temperature range 77 to 533°K and composition range 48.0 to 52.0 a/o Au. In addition to slip on the planes of the <001> zone, slip on planes of the <111> zone was also suggested by the slip trace analyses. This may account for the observed ductility and high work hardening rate. The composition dependence of the yield stress exhibited the following behaviour; 1) a minimum at the stoichiometric composition, 2) a linear dependence of hardening on the deviation from stoichiometry, 3) approximately equal hardening due to both excess Au and Zn atoms, and 4) a temperature independent hardening-composition slope (except at 77°K where a hardening minimum was observed at 50.5 a/o Au). The existing order strengthening theories and solid solution hardening mechanisms were found to be unsatisfactory for AuZn. The temperature dependence of the yield stress was similar to that observed for bcc metals and alloys with a rapid increase in yield stress at temperatures below 200°K. The excess Au atoms decreased the temperature dependence significantly in the composition range 50.1 to 51.6 a/o Au The temperature dependence of the yield stress was investigated using the thermally activated flow parameter analyses. The magnitude of the activation volume, activation energy, frequency factor and shear stress extrapolated to 0°K were consistent with the predictions of either the thermally activated cross-slip mechanism developed by Escaig or the Peierls-Nabarro force mechanism proposed by Rajnak and Dorn. The Peierls mechanism was found to provide a more satisfactory explanation of the solid solution softening phenomena. The defect structure of AuZn was determined to be antistructural. The larger Au atom expanded the lattice more than the smaller Zn atom constricted it. The as-extruded Zn-rich wire exhibited an anomalous increase in resistivity during annealing experiments. The increase and subsequent decrease were attributed to a variation in the degree of long-range order.
title: Water Quality Impact of Burning and Grazing On A Chained Pinyon-Juniper Site in Southeastern Utah
Creators: name: Buckhouse, John C.
Publisher: name: Utah State University
Year: 1975

description: During 1973 and 1974 a water quality study was conducted in San Juan County, southeastern Utah. In 1973, baseline water quality data was collected from study locations which had been chained to remove pinyon-juniper vegetation six years earlier. The area had been chained under two different techniques: (1) doubled chained, with debris-left-in-place and (2) chained, with debris windrowed. An "undisturbed, natural" woodland was left between these two treatments in order to serve as a control area.
In the fall of 1973 and spring of 1974 secondary treatments of burning and grazing were superimposed upon the debris-in-place and windrowed sites, respectively.
All water collected and analyzed for the several water quality parameters was generated through use of a small plot Rocky Mountain infiltrometer which creates a simulated rainstorm. Resultant runoff was collected and analyzed for each of the parameters in question.
No significant changes were noted from these point source measurements in terms of fecal and total coliform production (fecal pollution bacterial indicators). The point source approach was a technique for sampling a much larger land area through many small plots (0.23 m2). There is an element of risk involved whenever the data generated from such a small area is projected to the larger land area. Based on this small plot data it appears, however, that this level of livestock grazing (2 hectares/AUM) does not constitute a public health hazard in terms of fecal pollution indicators when grazed on similar semi-arid watershed areas.
Some significant changes were noted following burning, however. Significant increases in potassium and phosphorus were noted. Apparently the fire "released" these nutrients which were tied up in the debris scattered across the site. Potassium registered an increase of about 4 ppm (400 percent) while phosphorus showed an increase of about 0.2 ppm (400 percent). No significant treatment changes were detected for sodium, calcium, or nitrate-nitrogen, however.
Sediment production was also measured under the various treatment conditions. High natural variability is present among these sites, and no significant treatment effect was defected following our prescribed burning or grazing treatments.
Infiltration rates were also monitored. No significant treatment differences were noted among the initial treatment means during 1973. Apparently any differences in infiltration rates due to chaining technique had been overcome by the passage of six years since the initial chaining had been completed.
During 1974, however, secondary treatment was in effect. Infiltration rates on the grazed and burned watersheds were significantly depressed during certain time intervals in comparison to the "undisturbed, natural" woodland location. Apparently this level of secondary treatment could have an effect on the hydrology of the area, at least in terms of infiltration rates.
CP phase of nonuniversal $Z'$ on $\sinϕ^{J/Ψϕ}_s$ and T-odd observables of $\bar B_{q}\to V_{q} \ell^{+} \ell^{-}$

description: The evidence of a large CP phase has been shown by CDF and DØ collaborations in the time-dependent CP asymmetry (CPA) of $B_s\to J/Ψϕ$ decay, where the nonvanished CPA clearly implies the existence of a non-Kobayashi-Maskawa phase in $b\to s$ transition. We study the new phases originated by the extra family dependent $U(1)'$ model and examine their impact on $\hat{T}$ or CP violating observables in $\bar B_q\to V_q \ell^{+} \ell^{-}$ decays with $V_q=K^* (ϕ)$. Adopting the constraints from the current data of $Δm_s$ and the branching ratios for $\bar B_s\to μ^+ μ^-$ and $\bar B_q\to V_q\ell^+ \ell^-$, we find that $ϕ^{J/Ψϕ}_s=-(0.26\pm 0.22)$ and the T-odd observables of above 10% in the decay chain $\bar B_q\to V_q(\to Kπ[KK]) \ell^+ \ell^-$ can be achieved. In addition, we demonstrate that the longitudinal and transverse polarizations of $K^*$ and the up-down asymmetry of $K$ in the same decay chain are also sensitive to the $Z'$-mediated effects.

description: Americans across the nation are showing an increased awareness of the problems caused by the rapid and uncontrolled growth our country has undergone over the last fifty years. It is apparent to most that we can no longer abuse our natural resources as if they were inexhaustable. In the last few years, there has been a specific concern for prices, consumption, and energy conservation. These real concerns are moving us towards a reconsideration of our living habits that will certainly affect the future of residential planning and site design.

description: The recent BESIII data on $J/ψ\toγ(K_SK_Sπ^0)$, which is significantly more precise than earlier $η(1405/1475)$-related data, enables quantitative discussions on $η(1405/1475)$ at the previously unreachable level. We conduct a three-body unitary coupled-channel analysis of experimental Monte-Carlo outputs for radiative $J/ψ$ decays via $η(1405/1475)$: $K_SK_Sπ^0$ Dalitz plot distributions from the BESIII, and branching ratios of $γ(ηπ^+π^-)$ and $γ(γπ^+π^-)$ final states relative to that of $γ(K\bar{K}π)$. Our model systematically considers (multi-)loop diagrams and an associated triangle singularity, which is critical in making excellent predictions on $η(1405/1475)\to πππ$ lineshapes and branching ratios. The $η(1405/1475)$ pole locations are revealed for the first time. Two poles for $η(1405)$ are found on different Riemann sheets of the $K^*\bar{K}$ channel, while one pole for $η(1475)$. The $η(1405/1475)$ states are described with two bare states dressed by continuum states. The lower bare state would be an excited $η^\prime$, while the higher one could be an excited $η^{(\prime)}$, hybrid, glueball, or their mixture. This work presents the first-ever pole determination based on a manifestly three-body unitary coupled-channel framework applied to experimental three-body final state distributions (Dalitz plots).

description: Fundamental conservation laws predict ballistic, i.e., dissipationless transport behaviour in one-dimensional quantum magnets. Experimental evidence, however, for such anomalous transport has been lacking ever since. Here we provide experimental evidence for ballistic heat transport in a S=1/2 Heisenberg chain. In particular, we investigate high purity samples of the chain cuprate SrCuO2 and observe a huge magnetic heat conductivity $κ_{mag}$. An extremely large spinon mean free path of more than a micrometer demonstrates that $κ_{mag}$ is only limited by extrinsic scattering processes which is a clear signature of ballistic transport in the underlying spin model.

description: As with other regions of Iran, due to excessive extraction of groundwater for intense agricultural activity, Ghorveh plain, a water-scarce irrigation district in the west of Iran, has faced a serious water crisis during the last decade. The present study investigates the impacts of two scenario policies, namely, non-price policy (as a supply-oriented policy) and water pricing policies (as a demand-oriented policy) on agricultural sector of Ghorveh Plain, using positive mathematical programming (PMP). The model was calibrated by using farm-level data for the crop years in 2016–2017. Our findings indicate that applying water supply constraint policy will change the land use and cropping pattern to the crops with higher water productivity. The increase of water resource constraints can lead to the increase of water economic return which indicates a rising value of water resources shortage, warning the producers of the agriculture sector to allocate water to the crops with higher economic value under the water resources shortage conditions. In addition, the findings underline that in a situation where the price of irrigation water is low due to the low elasticity of water demand in the agriculture sector, formulating the economic instruments such as rising water prices does not solely suffice to achieve sustainable water resource management. However, mixed scenarios emphasized that the water distribution policies should be aligned with the increases in water cost. © 2019 by the authors.

description: Efimov effect is characterized by an infinite number of three-body bound states following a universal geometric scaling law at two-body resonances. In this paper, we investigate the influence of two-body loss which can be described by a complex scattering length $a_c$ on these states. Interestingly, because of the complexity of the scattering length $a_c$, the trimer energy is no longer constrained on the negative real axis, and it is allowed to have a nonvanishing imaginary part and a real part which may exceed the three-body or the atom-dimer scattering threshold. Indeed, by taking the $^{133}$Cs-$^{133}$Cs-$^6$Li system as a concrete example, we calculate the trimer energies by solving the generalized Skorniakov-Ter-Martirosian equation and find such three-body bound states with energies that have positive real parts and obey a generalized geometric scaling law. Remarkably, we also find that in some regions these three-body bound states have longer lifetimes compared with the corresponding two-body bound states. The lifetimes for these trimer states can even tend to infinity. Our work paves the way for the future exploration of few-body bound states in the complex plane.

description: Celem projektu było zbadanie obecności chorwackiej i serbskiej literatury dla dzieci i młodzieży w Polsce w latach 1945–1989, oszacowanie rozmiaru produkcji przekładowej z języka serbsko-chorwackiego oraz ustalenie chronologii wydawniczej zarówno wydań książkowych, jak i utworów opublikowanych na łamach czasopism „Płomyk”, „Płomyczek” i „Świerszczyk”. W trakcie badania poszerzono zakres eksploracji o przekłady z języka słoweńskiego i macedońskiego. Dzięki przeprowadzonym kwerendom w Bibliotece Narodowej i Muzeum Książki Dziecięcej w Warszawie, Bibliotece Narodowej Serbii (Narodna Biblioteka Srbije) oraz Bibliotece Narodowej i Uniwersyteckiej w Zagrzebiu (Nacionalna i sveučilišna knjižnica u Zagrebu) ustalono, że w badanym okresie polscy wydawcy opublikowali 40 przekładów książek (łącznie 43 wydania), w tym 28 przekładów (31 wydań) z języka serbsko-chorwackiego. Na łamach „Płomyka”, „Płomyczka” i „Świerszczyka” opublikowano natomiast 121 przekładów utworów jugosłowiańskich twórców: wierszy, opowiadań, baśni i fragmentów powieści. W toku badania potwierdzono, że wpływ na zakres i charakter importu utworów dla dzieci z Jugosławii miała struktura ówczesnego ryku wydawniczego, polsko-jugosłowiańskie kontakty kulturalne, które ulegały przemianom i nie zawsze przebiegały gładko i bezproblemowo, oraz brak specjalistów z zakresu literatury dziecięco-młodzieżowej tworzonej w Jugosławii.

description: A Hermitian metric on a complex manifold $(M, I)$ of complex dimension $n$ is called Calabi-Yau with torsion (CYT) or Bismut-Ricci flat, if the restricted holonomy of the associated Bismut connection is contained in ${\rm SU}(n)$ and it is called strong Kähler with torsion (SKT) or pluriclosed if the associated fundamental form $F$ is $\partial \overline \partial$-closed. In the paper we study the existence of left-invariant SKT and CYT metrics on compact semi-simple Lie groups endowed with a Samelson complex structure $I$. In particular, we show that if $I$ is determined by some maximal torus $T$ and $g$ is a left-invariant Hermitian metric, which is also invariant under the right action of the torus $T$, and is both CYT and SKT, then $g$ has to be Bismut flat.

description: Contact interaction is a fundamental concept that appears in various areas of physics. It simplifies physical models by replacing the detailed short-range interaction with a zero-range contact potential which reproduces the same low-energy scattering parameter, i.e. the $s$-wave scattering length. In this work, we generalize this concept to a system with short-range two-body loss. We show that the short-range two-body loss can effectively be replaced by a zero-range complex contact potential with proper regularization characterized by a complex scattering length. We develop appropriate ways to regularize this potential in the Lindblad master equation and apply them to the dynamic problem of Bose-Einstein condensate with weak interaction and two-body loss.

Monogamy of Correlations vs. Monogamy of Entanglement
Creators: name: Seevinck, Michael
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A fruitful way of studying physical theories is via the question whether the possible physical states and different kinds of correlations in each theory can be shared to different parties. Over the past few years it has become clear that both quantum entanglement and non-locality (i.e., correlations that violate Bell-type inequalities) have limited shareability properties and can sometimes even be monogamous. We give a self-contained review of these results as well as present new results on the shareability of different kinds of correlations, including local, quantum and no-signalling correlations. This includes an alternative simpler proof of the Toner-Verstraete monogamy inequality for quantum correlations, as well as a strengthening thereof. Further, the relationship between sharing non-local quantum correlations and sharing mixed entangled states is investigated, and already for the simplest case of bi-partite correlations and qubits this is shown to be non-trivial. Also, a recently proposed new interpretation of Bell's theorem by Schumacher in terms of shareability of correlations is critically assessed. Finally, the relevance of monogamy of non-local correlations for secure quantum key distribution is pointed out, although, and importantly, it is stressed that not all non-local correlations are monogamous.

description: This work contributes to smart systems research with a novel software architectureespecially designed for the support of the program comprehension and debuggingtasks.The aim of this thesis is to design a software architecture to ease developmenttasks and allow fast experimentation in smart system research laboratories. Thearchitecture consists of a distributed publish/subscribe middleware, agent-basedframeworks for development, and runtime environments for agent execution. ComplexEvent Processing (CEP) is integrated into this agent-based system in a novel,seamless way for both context handling and system status inspection to assist inprogram comprehension and debugging tasks.This work uses a mixed-methods methodology and contains three studies. Firstly,seven expert interviews were conducted to analyse requirements for architecturesin smart systems laboratory environments. Secondly, experiments to measuremessage latency and scalability of the implementation of the designed softwarearchitecture. And finally, an evaluation of the architecture using the ArchitectureTrade-off Analysis Method (ATAM).In addition to the requirements for software architectures for smart systems fromthe literature, such as scalability and heterogeneity, the expert interviews showthat for laboratory environments, support for program comprehension and debuggingis an important requirement. The conducted experiments revealed that thedeveloped software architecture meets the latency and scalability requirementsbecause the system scales with the number of middleware nodes and still hasaverage message round trip times of less than 4.6 ms with up to 10,000 agents.Furthermore, the results of the ATAM showed that the architecture meets all therequirements, both from the literature and the expert interviews. Thus, it can beused to support software development and rapid experimentation in smart systemenvironments.The results of this thesis could be used in the future to ease smart system researchexperiments with the presented architecture and the seamlessly integrated CEPengine.

Two first-order phase transitions in hybrid compact stars: higher-order multiplet stars, reaction modes and intermediate conversion speeds

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We study compact stars with hybrid equations of state consisting of a nuclear outer region and two nested quark phases, each separated from the lower density phase by a strong first-order phase transition. The stability of these models is determined by calculating their radial oscillation modes with different conversion rates between adjacent phases and hence junction conditions for the modes at the phase separation interface between them. In the case when the timescale of transition is faster than the period of oscillations, we recover the traditional stability criterion implying that $\partial M/\partialρ_c>0$ on the stable branch(es), where $M$ is the mass and $ρ_c$ is the central density. In the opposite limit of slow conversion, we find stable stellar multiplets beyond triplets consisting of stars that are stable by the usual criterion plus slow-conversion (denoted by $s$) hybrid stars with $\partial M/\partialρ_c<0$ that are stabilized due to an alternative junction condition on the fluid displacement field at the interface reflecting the slow rate of conversion. We also study the properties of the reaction mode, the radial mode that only exists for stars with rapid (abbreviated by $r$) phase transitions, in stars with either two rapid phase transitions or alternating rapid and slow phase transitions for the first time. The implications of alternative junction conditions are also examined, with these conditions generally being found to provide stability properties similar to those for a slow conversion rate.

title: Characteristics and Genesis of the Payson and Trenton Soils
Creators: name: Saif, Hakeem T.
Publisher: name: Utah State University
Year: 1977

description: It is necessary to study the genesis of the Payson and Trenton polypedons in northern Utah to understand why the Payson polypedon is an Alfisol, while the Trenton polypedon is a Mollisol. Even though the soil-forming factors appear similar, the soils differ at the order level. Two pedons, one belonging to the Payson polypedons and the other belonging to the Trenton polypedon, have been described and sampled by genetic horizons. Both pedons have essentially the same climate, slope, age, elevation, and are developed on the parent material of Lake Bonneville sediments.
The differences in physical, chemical and mineralogical properties among the horizons in the same pedon and between the Payson and Trenton pedons is due to differences in deposition as alluvium or lacustrine sediments during different periods.
The high amount of exchangeable sodium in both pedons reflects the development of texture in natric horizons and helps the movement of fine clay and organic matter from the eluvial to the illuvial horizons.
The light color of the surface of the Payson pedon is related to high amounts of calcium carbonate in the Al horizon, bleaching of soil particles within the structural units by sodium, and the presence of large amounts of light-colored minerals in the epipedon of the Payson soil.
Poetic synthesis : a study of form and subject in the poetry of Marianne Moore
Creators: name: Shelbourn, Judith Anne Blakeston
Publisher: name: University of British Columbia
Year: 2011

description: One of the popular trends of modern literary criticism has emphasized the unity of form and subject as a first principle of a poem. Marianne Moore provides a thoroughly solid example of this principle in much of her poetry; the moral themes of her poems are reflected in her precise handling of the craftmanship of the poetic form. It is the purpose of this essay to review Miss Moore’s poetry within the implication of the phrase "poetic synthesis". In order for her poems to work for all levels of critical direction, that is language, metre, rhyme, metaphor, symbol, and philosophic,—and in her particular case- moral, theme, the reader must be aware of the singular unity of the poems. In other words, each of the facets of the constructed prism - poem reflects by its construction the light which comes the creative source of the poet: the act of the statement is the essence of the statement. This idea is the controlling method of this particular thesis: the work dealt with includes a range of material from fifty years of Miss Moore's publication of her poetry. For the most part, selections from her Collected Poems provide the basis of discussion. No attempt is made to asses her work chronologically since the selections in the Collected Poems contain works that will have a fixed importance regardless of their time sequence. The first chapter offers a close reading of poems in terms of the concept of the poetic synthesis. References are made to the deliberately controlled metric and syllabic system which is found in most of her works as well as to the many types of rhyme that contribute to the structural unity of the poem. Some mention is made of the moral themes which occur in many of the works, often with reference to the “armoured" metaphor of which she is so fond. The second chapter suggests some comparisons between Miss Moore and several of her contemporary writers; William Carlos Williams and Wallace Stevens, to show how, against the Imagist background, each of these poets projects a particular concern in both technique and theme. No mention has been made of Miss Moore's most recent publication since the thesis had been written and approved before its appearance.

title: The Effects of Gully Plugs and Contour Furrows on Erosion and Sedimentation in Cisco Basin, Utah
Creators: name: Thomas, Dee B.
Publisher: name: Utah State University
Year: 1975

description: Soil surface treatments consisting of gully plugs and contour furrows were constructed as a means of reducing erosion and holding sediment on site.
To measure the effectiveness of the gully plugs and furrows, angle iron stakes and profile transects were installed to measure soils loss and accompanying change in the soil profile. The profile transects gave a reliable measure of the change in the height of the soil surface in constructed pits and across contour furrows. Because of the shrinking and swelling of the soil, the change in height of the angle iron stakes was found to be much more than the reduction in soil surface caused by erosion.
High intensity thunderstorms, occuring mostly during July, August, and September, cause most of the erosion from the semi-arid land.
The gully plugs and contour furrows were effective in holding runoff and sediment on site, but the life expectancy of the treatments is only about fifteen years.

description: Celem projektu było zbadanie obecności chorwackiej i serbskiej literatury dla dzieci i młodzieży w Polsce w latach 1945–1989, oszacowanie rozmiaru produkcji przekładowej z języka serbsko-chorwackiego oraz ustalenie chronologii wydawniczej zarówno wydań książkowych, jak i utworów opublikowanych na łamach czasopism „Płomyk”, „Płomyczek” i „Świerszczyk”. W trakcie badania poszerzono zakres eksploracji o przekłady z języka słoweńskiego i macedońskiego. Dzięki przeprowadzonym kwerendom w Bibliotece Narodowej i Muzeum Książki Dziecięcej w Warszawie, Bibliotece Narodowej Serbii (Narodna Biblioteka Srbije) oraz Bibliotece Narodowej i Uniwersyteckiej w Zagrzebiu (Nacionalna i sveučilišna knjižnica u Zagrebu) ustalono, że w badanym okresie polscy wydawcy opublikowali 40 przekładów książek (łącznie 43 wydania), w tym 28 przekładów (31 wydań) z języka serbsko-chorwackiego. Na łamach „Płomyka”, „Płomyczka” i „Świerszczyka” opublikowano natomiast 121 przekładów utworów jugosłowiańskich twórców: wierszy, opowiadań, baśni i fragmentów powieści. W toku badania potwierdzono, że wpływ na zakres i charakter importu utworów dla dzieci z Jugosławii miała struktura ówczesnego ryku wydawniczego, polsko-jugosłowiańskie kontakty kulturalne, które ulegały przemianom i nie zawsze przebiegały gładko i bezproblemowo, oraz brak specjalistów z zakresu literatury dziecięco-młodzieżowej tworzonej w Jugosławii.

description: Studies were conducted to determine the effect of externally applied growth hormones on winter rye (Secale cereale var. cougar). The rye was grown under the snow in a specially prepared tunnel on a mountain side near Logan, Utah. These plants showed a remarkable ability to grow at 0°C. Three growth hormones, kinetin, gibberellic acid (GA), and auxin (indole-3-acetic acid) were externally applied to rye seedlings growing in the tunnel. These seedlings were alter weighed, measured and tested for soluble protein content. The three hormone treatments had no significant effects on the fresh weights or shoot lengths of the rye. GA however, had a significant effect on the soluble protein content of the young shoots. Shoots treated with GA showed a marked decrease in soluble protein content. Kinetin and IAA had no significant effect on the soluble protein content of the rye.

description: We present model-marginalized limits on mixed hot dark matter scenarios, which consider both thermal neutrinos and thermal QCD axions. A novel aspect of our analyses is the inclusion of small-scale Cosmic Microwave Background (CMB) observations from the Atacama Cosmology Telescope (ACT) and the South Pole Telescope (SPT), together with those from the Planck satellite and Baryon Acoustic Oscillation (BAO) data. After marginalizing over a number of well-motivated non-minimal background cosmologies, the tightest $95\%$ CL upper bound we obtain is $0.21$ eV, both for $\sum m_ν$ and $m_{\rm a}$, from the combination of ACT, Planck and BAO measurements. Restricting the analyses to the standard $Λ$CDM picture, we find $\sum m_ν<0.16$ eV and $m_{\rm a}<0.18$ eV, both at $95\%$ CL. Interestingly, the best background cosmology is never found within the minimal $Λ$CDM plus hot relics, regardless of the data sets exploited in the analyses. The combination of Planck with either BAO, SPT or ACT prefers a universe with a non-zero value of the running in the primordial power spectrum with strong evidence. Small-scale CMB probes, both alone and combined with BAO, either prefer, with substantial evidence, non-flat universes (as in the case of SPT) or a model with a time varying dark energy component (as in the case of ACT).

description: We propose a design for the magnetic memory cell which allows an efficient storage, recording, and readout of information on the basis of thin film ferromagnetic nanorings. The information bit is represented by the polarity of a stable 360$^\circ$ domain wall introduced into the ring. Switching between the two magnetization states is achieved by the current applied to a wire passing through the ring, whereby the $360^\circ$ domain wall splits into two charged $180^\circ$ walls, which then move to the opposite extreme of the ring to recombine into a $360^\circ$ wall of the opposite polarity.
title: Anatomical Effects of Dicamba on Pea Root Tissues
Creators: name: Ovard, Brent George
Publisher: name: Utah State University
Year: 1974

description: Peas (Pisum Sativum L. Var Alaska) were allowed to absorb calcium and magnesium chloride for 8 hours and then were germinated in a potassium phosphate buffer pH 6.5 for 40 hours. Peas were then treated with 0, 0.1, 0.3, or 0.5 ppm dicamba (3,6-dichloro-o-anisic acid) and harvested at 24, 48, and 72 hour intervals. The following determinations were recorded: Root elongation, nuclear volume, and anatomical modifications.
Root elongation recordings showed that dicamba prevented normal root elongation. Treatments induced very short thick primary roots.
Measurements of nuclear volume indicated that all herbicide concentrations were able to reduce the total volume. Several other compounds, (chloramphenicol, actinomycin D and colchicine), were introduced to better characterize the actions of dicamba. Chloramphenicol and colchicine were responsible for nuclear volume reductions.
Dicamba induced major anatomical alterations of treated pea roots. In the region 1 millimeter from the root tip, cortical cells were induced to divide more profusely. The diameter of treated roots exceeded that of untreated root tips.
In the region 3 millimeters from the root tip, excessive cellular division and swelling resulted in cortical damage.
title: Economic Feasibility of Controlling Big Sagebrush (Artemisia tridentata) on State and Private Rangelands in Utah

description: Spraying with the chemical herbicide 2,4-D is the most widely used method of controlling big sagebrush. Spraying is very effective in increasing forage production and generally is not poisonous to either man or animals.
Two procedures can be used to calculate the internal rate of return to big sagebrush control: standard and modified discounting. Standard discounting assumes all nonuse costs are incurred in the year of treatment, and the annual income stream is constant throughout the effective life of treatment. Modified discounting correctly assumes the nonuse cost is incurred in the period of deferment, and the income stream does not reach its full potential until after deferment. Thus, modified discounting yields a lower internal rate of return.
Three big sagebrush control methods (spraying, burning, and chaining) offer internal rates of return which are greater than 8 percent (cost of obtaining capital for range improvement).
The most important factors in determining the internal rate of return are the site vigor index and the amount of forage present before treatment. A larger pre-treatment forage yield will give a larger internal rate of return, assuming the vigor index is sufficiently high.
If state and private rangelands infested with big sagebrush are not improved by spraying or other big sagebrush control methods, certain benefits, called opportunity costs, will be foregone. For spraying alone, the expected annual opportunity costs would be $3,048,102.
The economic feasibility of controlling nearly 2 1/2 million acres of state and private rangelands infested with big sagebrush are excellent. The expected annual increase in carrying capacity of 1,830,000 acres of sagebrush rangeland meriting improvement by spraying is 765,855 AUMs. The remaining 623,000 acres meriting control other than by spraying could possibly increase the total number of additional AUMs to over 1 million.
title: Blue Grouse Ecology and Habitat Requirements in North Central Utah

Publisher: name: Utah State University
Year: 1972

description: The ecology and habitat requirements of a population of blue grouse were studied during 1970 and 1971 on the Cache National Forest 25 miles south of Logan, Utah.
Baseline data concerning numbers of blue grouse, vegetative composition, and insect abundance on the study area were gathered. These data were to be compared to similar measurements made following a herbicidal spraying of the area during 1972.
Information concerning the breeding, nesting, brood rearing, and wintering habits of the grouse was also collected. Male blue grouse migrated to the study area in early April to set up territories. These were located on open tree-shrub hillsides. Seven nests were located under sagebrush bushes. About 18 to 20 broods were on the study area during 1971. Young grouse consumed insects primarily during the summer. Males migrated from area by July and females and broods moved off in late August and early September.
