Probability Landscape and Its Rotational Flux in Complex Systems: Construction and Topological Structure
Creators: name: Manuchehrfar, Farid
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Biomolecules such as proteins, DNAs, and RNA interact in cells to regulate cellular functions. These interactions can be modeled as reaction networks. At small copy numbers, there is strong stochasticity in the network due to thermal fluctuations. Such stochasticity plays important roles in cellular functions. Stochasticity can be investigated using models of stochastic chemical kinetics (SCK), which is governed by the discrete chemical master equation (dCME). The probability landscapes over the discrete states of copy numbers of molecules are dictated by the dCME of networks and provide detailed information on these stochastic processes. However, there are two difficulties. First difficulty is that there are often many molecular species. Thus, stochastic networks are usually of high dimensionality. The exact computation of the probability landscape is challenging because of the high dimensionality. Second, even if one can construct a landscape accurately, it is difficult to navigate and understand the high dimensional probability landscape, to gain insight into the stochastic behavior of the system. This work addresses these two difficulties. First, we expand the theoretical framework for state space truncation and provide the error bounds for truncating the state space 1) below a specific total mass of the system, 2) below a minimum copy number of each molecular specie in the network, and 3) over a maximum copy number of each molecular specie in the reaction network, and provide error for such truncations. Second, we develop algorithms to characterize topological structure of high dimensional probability surfaces. Third, we formulate the concept of the rotation of probability flux governed by reaction stoichiometry in discrete space using 1-forms. Our analysis reveals important findings in a number of dynamic processes, including phenotypic switching in feedback loops, high dimensional repressilator networks, and activated process of alanine dipeptide isomerization in vacuum. Our findings were not possible without the concepts and algorithms developed in this work.
Characterization of Physicochemical Parameters for Tap Water and Removal of Hardness Using Moringa Stenopetala seed as Natural Absorbent The Case of Mekelle Town, Tigray Ethiopia

description: The physicochemical examination of tap water used for domestic purposes in Mekelle town was carried out to ascertain their suitability for consumption. Water softening experiments were also conducted to observe the changes in total hardness, with varying dosages of a natural coagulant. The natural coagulant was extracted from Moringa stenopetala seed A total of twenty (20) water samples were collected from various parts of the town tap water used for domestic purposes and characterized for their physicochemical parameters, arising public interest. The physicochemical implications render Mekelle's tap water unfit for human consumption, though it can be used for other purposes. Tap water samples containing high concentration of hardness from Mekelle town, Enda Mariam and Enda Giyorgis areas were used for hardness removal mechanism part of this study. The optimum hardness removal efficiency for Mekelle tap water sample produced from ground water source was approximately 58 % (from initial total hardness of 523.25 to final hardness result of 220.3 which is within Ethiopian and WHO standard, i.e. below 300 mg/l as CaCO3) which was attained at M.Stenopetala dosage of 200 mg/l. The optimum hardness removal efficiency for synthetic hard water analysis done by taking two factors, coagulant dose concentration and PH as independent factors was approximately 49 % (from 500 to 256.6 mg/l as CaCO3) which was attained at M.Stenopetala dosage of 200 mg/l and 6.5 PH value. The mechanism for hardness removal in hard water seems to be precipitation of insoluble products of the reaction between M.Stenopetala extract and the hardness causing ions. Even at a relatively higher dosage of the M.Stenopetala coagulant compared to the chemical softening, natural coagulant is preferred for economic use, health and environmental safety.

title: Shakespeare and the idea of metamorphosis
Creators: name: Hart, B
Publisher: name: University of Kent
Year: 1983

description: This study attempts to discover what is comprehended by the title of Ovid's Metamorphoses and what it was about this narrative poem which Shakespeare found so congenial. The opening chapters explore the variety and coherence of Ovid's theme, whilst ranging widely over Shakespeare's poems and plays and elucidating the Renaissance context in which the poem was received. Consideration is given to the way Ovid and Shakespeare place human action in an interpretative context of the natural world. It is argued that natural settings and natural imagery condition both the presentation of and our response to the marvelous events which occur in the fictions of both poets. A further fundamental continuity between Ovid and Shakespeare is their concern with language and the imagination as transforming media which dynamically influence human perception. The connection between metaphor and metamorphosis is examined, and it is argued that the triad of lunatic, lover, and poet is as significant in the Metamorphoses as it is in Shakespeare's plays from A Midsummer Night's Dream to The Tempest. Ovid's use of language was of considerable consequence in the Renaissance. However, this study suggests that, for Shakespeare, the most important rhetorical quality of Ovid was his view of literature and society. Thus an important aim is to relate Ovid's perception of the artist's role, and the relationship between poet and poem, poem and reader, which the Metamorphoses establishes, to the aesthetic character of individual Shakespearean works and to Shakespeare's developing perception of his role as a theatre poet. The second part of the study is a close consideration of three plays - As You Like It, All's Well That Ends Well, and Antony and Cleopatra - in the light of the critical context established in the opening chapters. Attention is given to Shakespeare's engagement with problems of authorial intention and critical interpretation (a word which also means translation), and the motif of Ovid's banishment is seen as central to the dramatist's examination of the licensed affective attitude of 'as you like it'. A contrast is made between the moralist's demand for fixed and singular denotation and meaning, and the imaginative artist's exploitation of linguistic ambiguity and change. Here Florio and Montaigne serve as foils to Ovid, and it is argued that Shakespeare's 'idea of metamorphosis is increasingly manifest as a desire to find a form of imaginative fiction which can match the rich variety of the natural world and keep time with its changes. Like the Metamorphoses, the text of All's Well is deliberately left 'unsealed'. Similarly, Antony and Cleopatra is a truly aleatory work whose meaning can only be realized in 'performance' - an ambiguous word which, as used in these plays, also reflects Shakespeare's willingness to follow Ovid in accepting the risks incurred by the full expression of human sexuality.

description: Spike generation in neurons produces a temporal point process, whose statistics is governed by intrinsic phenomena and the external incoming inputs to be coded. In particular, spike-evoked adaptation currents support a slow temporal process that conditions spiking probability at the present time according to past activity. In this work, we study the statistics of interspike interval correlations arising in such non-renewal spike trains, for a neuron model that reproduces different spike modes in a small adaptation scenario. We found that correlations are stronger as the neuron fires at a particular firing rate, which is defined by the adaptation process. When set in a subthreshold regime, the neuron may sustain this particular firing rate, and thus induce correlations, by noise. Given that, in this regime, interspike intervals are negatively correlated at any lag, this effect surprisingly implies a reduction in the variability of the spike count statistics at a finite noise intensity.

description: Zur Minderung des Klimawandels ist es von Bedeutung, Faktoren zu identifizieren, welche das Umweltverhalten der Menschen beeinflussen. In der Umweltverhaltensforschung wurde vielfach bestätigt, dass mehr Naturkontakt und eine ausgeprägtere Naturverbundenheit mit einem höheren Umweltverhalten einhergehen. Das Ziel der vorliegenden Masterarbeit ist es herauszufinden, inwiefern auch die Bergwanderhäufigkeit mit der Ausprägung des Umweltverhaltens und der Ausprägung der Naturverbundenheit zusammenhängt. Um diese Forschungsfrage zu beantworten, wurde eine quantitative Onlineumfrage (N = 346) durchgeführt. Die Ergebnisse zeigen, dass die Ausprägung des selbstberichteten Umweltverhaltens und der Naturverbundenheit von Bergwander*innen signifikant höher ist als die von Nicht-Bergwander*innen und die Ausprägung des selbstberichteten Umweltverhaltens und der Naturverbundenheit von intensiv bergwandernden Personen (>10 Tage pro Jahr) signifikant höher ist als die von moderat bergwandernden Personen (1-10 Tage pro Jahr). Diese Erkenntnisse weisen erstmals in die Richtung, dass es sich beim Bergwandern um eine wirkungsvolle Intervention zur Umweltverhaltenserhöhung handeln könnte. Zur Überprüfung dieser Vermutung bedarf es jedoch weiterführender experimenteller Forschung.

description: The distribution of Milky Way halo blue horizontal-branch (BHB) stars is examined using action-based extended distribution functions (EDFs) that describe the locations of stars in phase space, metallicity, and age. The parameters of the EDFs are fitted using stars observed in the Sloan Extension for Galactic Understanding and Exploration-II (SEGUE-II) survey that trace the phase-space kinematics and chemistry out to ~70 kpc. A maximum a posteriori probability (MAP) estimate method and a Markov Chain Monte Carlo method are applied, taking into account the selection function in positions, distance, and metallicity for the survey. The best-fit EDF declines with actions less steeply at actions characteristic of the inner halo than at the larger actions characteristic of the outer halo, and older ages are found at smaller actions than at larger actions. In real space, the radial density profile steepens smoothly from -2 at ~2 kpc to -4 in the outer halo, with an axis ratio ~0.7 throughout. There is no indication for rotation in the BHBs, although this is highly uncertain. A moderate level of radial anisotropy is detected, with $β_s$ varying from isotropic to between ~0.1 and ~0.3 in the outer halo depending on latitude. The BHB data are consistent with an age gradient of -0.03 Gyr kpc$^{-1}$, with some uncertainty in the distribution of the larger ages. These results are consistent with a scenario in which older, larger systems contribute to the inner halo, whilst the outer halo is primarily comprised of younger, smaller systems.

description: We investigate for order and chaos the dynamical system of a spinning test particle of mass $m$ moving in the spacetime background of a Kerr black hole of mass M. This system is approximated in our investigation by the linear in spin Hamiltonian function provided in [E. Barausse, and A. Buonanno, Phys.Rev. D 81, 084024 (2010)]. We study the corresponding phase space by using 2D projections on a surface of section and the method of color and rotation on a 4D Poincaré section. Various topological structures coming from the non-integrability of the linear in spin Hamiltonian are found and discussed. Moreover, an interesting result is that from the value of the dimensionless spin $S/(m M)=10^{-4}$ of the particle and below, the impact of the non-integrability of the system on the motion of the particle seems to be negligible.

description: Fossil fuel based plastic raw materials are not renewable which in questioned their sustainability as well as the plastic products of these raw material is sources of an overwhelming environmental problem due recalcitrant to degradation. Hence, there is an urgent need toward bio-based plastics research area particularly poly lactic acid (PLA). This study aimed to produce Lactic acid which is used as a raw material for bio-based plastic (PLA) by a bacteria Lacto bacillus plantarum using sugarcane bagasse as a carbon source. The effects of glucose concentration, time and pH on the lactic acid yield were studied. sugarcane bagasse was pretreated using dilute sulfuric acid as catalyst and a maximum glucose concentration of 3.755g/L was found at a temperature of 105 C, acid concentration of 2.75% and time of 3hrs.The fermentation experiments were performed in 250 mL Erlenmeyer flasks as small scale laboratory fermenter containing 100 mL of hydrolysate supplemented with 5g/L of yeast extract and 10mL of lacto-bacillus plantarum inoculum. The yield of lactic acid from the fermented broth was determined using HPLC. Response surface methodology (RSM) approach of Design expert software of version 11 was used to analyze the effects of glucose concentration (3.755g/L, 3.58.g/L and 3.42g/L), pH (4, 6 and 8) and incubation time (10hrs, 20hrs and 30hrs) on lactic acid production with their respective ranges keeping the temperature and agitation speed constant. A three-variable, three-level Box-Behnken design was used to develop a statistical model to describe the relationship between lactic acid concentration and the chosen independent variables and to observe their effects on the yield using RSM. The model was statistically significant (p ˂0.0001), did not show lack of fit (p-value = 0.1141) and The Pred R-Squared of 0.9764 is in reasonable agreement with the Adj R-Squared of 0.9956.From the model regression equation developed, the linear terms of glucose concentration, pH and time and pure quadratic term of time as well as interaction of glucose concentration and pH, interaction of glucose concentration and time, and interaction of pH and time had positive effect on the response yield. On the other hand pure quadratic terms of glucose concentration and pH had negative effect on the response yield. The maximum yield of lactic acid of 15.79g/L was found at a higher glucose concentration of 3.755g/L, at a moderate pH of 6 and at a maximum time of 30hrs.

City of Black Women's Shoulders: Examining Policy-Relevant Educational Efforts for Liberation in Chicago
Creators: name: Green, Glenance  LaVerne
Publisher: name: University of Illinois at Chicago
Year: 2023

description: This study examines how Black women leading Black-led organizations (BLOs) work toward Black liberation, and the characteristics or attributes that exist across BLOs led by Black women. It explores how Black women lead and whether the approaches they are using to help us get free leverage similar strategies, independent of one another. I argue that education policy must be contextual and rooted in the assets and educational practices of the communities most harmed and historically disproportionately impacted, particularly those led by Black women. I also argue that, based on our collective marginalized identities of being Black and woman, we negotiate and navigate policy-relevant priorities in alignment with the expertise of our lived experiences to strategically advance an agenda toward the liberation of all people. I leverage Black Feminist Thought and radical Black feminism as the overarching theoretical frameworks to autoethnographically tell this story through the lens and work of the Black Researchers Collective, a grassroots community-based organization on the south side of Chicago training and equipping communities with research tools to be more civically engaged and policy informed. This study includes the collection and analysis of program workshop applicant data (n=155), 129 participant workshop surveys (n=43), 200 participant workshop journals (n=50), post-program workshop interviews (n=7), Board meeting observations (n=10), and interviews with Black women working within (n=8) and external to (n=16) the Black Researchers Collective. Study findings indicate that Black women are resisting through education. Black women across the south and west sides of Chicago are developing, curating, and employing various education models in community as a key mechanism to collectively resist systems of oppression and collectively help us get free. Black women are using varied educational techniques and strategies to carry out and amplify their organization's mission and values; the successful outcomes of which suggest possible implications for education policy on a state and local level.

description: Solid waste handling and disposal are the pressing problems in Addis Ababa City. Millions of tons of municipal solid waste, hazardous/industrial wastes and commercial xi wastes are handled daily throughout municipal areas. Addis Ababa cleansing management agency confronted with great challenges in disposing of solid wastes in an efficient, cost effective and environmentally safe manner. The total quantity of MSW generated at the site was 3800m3/day or 760 ton/day, annually 1,387,000 m3 Based on the results obtained, I recommended that the municipal solid waste at Reppi Dump Site is feasible for incineration as a strategy to reduce the amount of disposed waste and energy recovery.. Knowledge of the energy potential of MSW for incineration is necessity, in order to plan for energy recovery from MSW. Energy potential from municipal solid waste for incineration was done in an area called Reppi /Koshe, which is the only dumpsite in the city, with objective of evaluating energy potential (heating value) of municipal solid waste and feasibility for incineration. Solid waste sampling and laboratory analysis were carried out according to the random sampling method based on American Society of Testing and Materials (ASTM) standards to determine the waste compositions and proximate analysis. The laboratory work undertaken at school of chemical and bioengineering and Arat kilo chemistry department. According to the weekly analysis the main compositions of the generated MSW in the site were food waste, chat waste and fruit waste which accounted 65% by weight. In this work an average calorific value of 19.78 MJ/kg with variable high water content of 44-65% was determined. Based on the average calorific value, moisture content and MSW removed the net energy potential is 7.68 MJ/Kg with 84.5% energy efficiency.

Lett. 111, 230401 (2013)] and [J. Phys. A. 46, 272002 (2013)]. The results give rise to state independent uncertainty relations satisfied by any nonnegative Schur-concave functions. On the other hand, a remarkable recent result of entropic uncertainty relation is the direct-sum majorization relation. In this paper, we illustrate our bounds by showing how they provide a complement to that in [Phys. Rev. A. 89, 052115 (2014)].
On the characterization of Triebel--Lizorkin type spaces of analytic functions
Creators: name: Rydhe, Eskil
Publisher: name: arXiv
Year: 2016
Subjects: subject: Functional Analysis (math.FA)
subject: FOS: Mathematics

description: We consider different characterizations of Triebel--Lizorkin type spaces of analytic functions on the unit disc. Even though our results appear in the folklore, detailed descriptions are hard to find, and in fact we are unable to discuss the full range of parameters. Without additional effort we work with vector-valued analytic functions, and also consider a generalized scale of function spaces, including for example so-called $Q$-spaces. The primary aim of this note is to generalize, and clarify, a remarkable result by Cohn and Verbitsky, on factorization of Triebel--Lizorkin spaces. Their result remains valid for functions taking values in an arbitrary Banach space, provided that the vector-valuedness "sits in the right factor". On the other hand, if we impose vector-valuedness on the "wrong" factor, then the factorization fails even for separable Hilbert spaces.
Multiscale Simulations and Pharmacokinetic Modeling of Long-Acting Injectable Delivery Systems

Modelling and simulation

description: Long-acting injectables (LAI) offer many practical benefits for patients in improving drug adherence to therapies for chronic diseases. LAI, administered either subcutaneously (SC) or intramuscularly (IM), can improve drug bioavailability, and reduce frequency of administration as well as regimen complexity. SC also has additional benefits over IM injections as being safer, less painful, and able to be administered at home. However, development and translation of these products into the clinic is often limited because of physiological complexity at injection site, such that absorption rate mechanisms are not well understood. Common predictive and correlative methods used in oral formulations, such as in vitro-in vivo correlations, are not well suited for SC physiology and are only capable of measuring a few parameters at a time, meaning relationships between parameters cannot be discriminately measured.
 This project seeks to address this gap in knowledge by using computation to bridge the gap between suboptimal preclinical testing methods and human pharmacokinetic data. A Multiscale framework was developed by integrating a first-principles Multiphysics model of the SC space to experimental plasma concentration profiles using simulated absorption rates. First, our lab’s previous framework for lymphatic absorption of monoclonal antibodies (mAbs) was converted into small molecule absorption into the capillaries. Drug and formulation critical quality attributes (CQA) were determined for a solution injection of methotrexate, and a nanocrystal formulation of medroxyprogesterone acetate (MPA, Depo-SubQ Provera). Two dissolution models were incorporated to compare the difference between using average particle size (Noyes-Whitney) and particle size distributions (Population Balance Model, PBM) as CQA for nanocrystal LAI specifically. Absorption rates were validated using compartmental pharmacokinetic models, and sensitivity analyses were conducted to determine model parametric sensitivity. Overall, the modeling framework was able to determine the importance of and discriminate the effect of parameters on SC absorption rates.

description: The field and temperature dependencies of the longitudinal and Hall resistivity have been measured for FeSe${}_{1-x}$S${}_{x}$ (x=0.04, 0.09 and 0.19) single crystals. The sample FeSe${}_{0.81}$S${}_{0.19}$ does not show a transition to an orthorhombic phase and exhibits at low temperatures the transport properties quite different from those of orthorhombic samples. The behavior of FeSe${}_{0.81}$S${}_{0.19}$ is well described by the simple two band model with comparable values of hole and electron mobility. In particular, at low temperatures the transverse resistance shows a linear field dependence, the magnetoresistance follow a quadratic field dependence and obeys to Kohler's rule. In contrast, Kohler's rule is strongly violated for samples having an orthorhombic low temperature structure. However, the transport properties of the orthorhombic samples can be satisfactory described by the three band model with the pair of almost equivalent to the tetragonal sample hole and electron bands, supplemented with the highly mobile electron band which has two order smaller carrier number. Therefore, the peculiarity of the low temperature transport properties of the orthorhombic Fe(SeS) samples, as probably of many other orthorhombic iron superconductors, is due to the presence of a small number of highly mobile carriers which originate from the local regions of the Fermi surface, presumably, nearby the Van Hove singularity points.
Removal of Some Selected Heavy Metal Using Modified Bagasse and Eucalyptus Bark from Gold Mining Waste Water: Case Study of Ezana (Meli) Gold Mining Development Plc Industries
Creators: name: Mebrahtom, Hagos
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study investigated the potential use of modified bagasse (MSB) and eucalyptus Bark (EB) treated from sample wastewater in batch mode experiments. The discharge of untreated gold mining wastewater contaminates with heavy metals such as Cu (II) and Pb (II), which is threatening ecosystems, carcinogenic to the human & hinder development of plants. Since the removal by adsorption is cost effective, not time consuming and environmentally friendly, it has been widely studied by many scholars for remediation of heavy metals. Characterization of bagasse and eucalyptus bark were analyzed using proximate analysis like MC (%), Ash value (%), ƍ b (g/cm 3 ), VM (%), fixed carbon (%) and % (C, N 2 ). FTIR analysis revealed the presence of multiple functional groups in the adsorbent, some of which were involved in the sorption process and x-ray diffraction (XRD) used to measure the crystalline content of adsorbent materials. The result indicated that the effluents discharged from Ezana Gold extraction were mainly contains the following: TSS (ppm), turbidity (NTU), EC (µs/cm), TDS (ppm), COD (ppm), temperature(°C), pH, cyanide WAD with <11°C (ppm) and heavy metals such as Fe > Cu >Pb >Mn > Cr (VI) >Zn > Co > Ni > Cd (ppm). They were determined by atomic absorption spectroscopy. The major pollutants selected from the process effluent were Cu 2+ and Pb 2+ due to exceeded standard discharge limits. The objective of the study was removal of Cu 2+ and Pb 2+ from rich Ezana wastewater using modified sugarcane bagasse and eucalyptus bark powder as an adsorbent. The selected parameters were pH, adsorbent dose and time. A maximum removal of (Cu 2+ , Pb 2+ ) by modified bagasse (88.45%, 94%) and eucalyptus bark (92%, 99%) respectively was achieved. The adsorption data were well fitted to the Langmuir isotherm model and pseudo-second order kinetic model for both modified bagasse (Cu, Pb) and eucalyptus bark (Cu, Pb). This indicated that Eucalyptus bark powder was more effective than modified bagasse (MSB) and it can be used as an alternative low cost adsorbent for the removal of copper and lead from Ezana mining wastewater.

description: We compute one loop free energy for D=4 Vasiliev higher spin gravities based on Konstein-Vasiliev algebras hu(m;n|4), ho(m;n|4) or husp(m;n|4) and subject to higher spin preserving boundary conditions, which are conjectured to be dual to the U(N), O(N) or USp(N) singlet sectors, respectively, of free CFTs on the boundary of $AdS_4$. Ordinary supersymmetric higher spin theories appear as special cases of Konstein-Vasiliev theories, when the corresponding higher spin algebra contains $OSp({\cal N}|4)$ as subalgebra. In $AdS_4$ with $S^3$ boundary, we use a modified spectral zeta function method, which avoids the ambiguity arising from summing over infinite number of spins. We find that the contribution of the infinite tower of bulk fermions vanishes. As a result, the free energy is the sum of those which arise in type A and type B models with internal symmetries, the known mismatch between the bulk and boundary free energies for type B model persists, and ordinary supersymmetric higher spin theories exhibit the mismatch as well. The only models that have a match are type A models with internal symmetries, corresponding to $n=0$. The matching requires identification of the inverse Newton's constant $G_N^{-1}$ with $N$ plus a proper integer as was found previously for special cases. In $AdS_4$ with $S^1\times S^2$ boundary, the bulk one loop free energies match those of the dual free CFTs for arbitrary $m$ and $n$. We also show that a supersymmetric double-trace deformation of free CFT based on OSp(1|4) does not contribute to the ${\cal O}(N^0)$ free energy, as expected from the bulk.

description: A significant fraction of nearby young moving group members harbor circumstellar debris dust disks. Due to their proximity and youth, these disks are attractive targets for studying the early evolution of debris dust and planetesimal belts. Here we present 70 and 160$μ$m observations of 31 systems in the $β$ Pic moving group, and in the Tucana-Horologium, Columba, Carina and Argus associations, using the Herschel Space Observatory. None of these stars were observed at far-infrared wavelengths before. Our Herschel measurements were complemented by photometry from the WISE satellite for the whole sample, and by submillimeter/millimeter continuum data for one source, HD 48370. We identified six stars with infrared excess, four of them are new discoveries. By combining our new findings with results from the literature, we examined the incidence and general characteristics of debris disks around Sun-like members of the selected groups. With their dust temperatures of <45 K the newly identified disks around HD 38397, HD 48370, HD 160305, and BD-20 951 represent the coldest population within this sample. For HD 38397 and HD 48370, the emission is resolved in the 70$μ$m PACS images, the estimated radius of these disks is ~90 au. Together with the well-known disk around HD 61005, these three systems represent the highest mass end of the known debris disk population around young G-type members of the selected groups. In terms of dust content, they resemble the hypothesized debris disk of the ancient Solar System.

description: Brown dwarf disks are excellent laboratories to test our understanding of disk physics in an extreme parameter regime. In this paper we investigate a sample of 29 well-characterized brown dwarfs and very low mass stars, for which Herschel far-infrared fluxes as well as (sub)-mm fluxes are available. We have measured new Herschel PACS fluxes for 11 objects and complement these with (sub)-mm data and Herschel fluxes from the literature. We analyze their spectral energy distributions in comparison with results from radiative transfer modeling. Fluxes in the far-infrared are strongly affected by the shape and temperature of the disk (and hence stellar luminosity), whereas the (sub)-mm fluxes mostly depend on disk mass. Nevertheless, there is a clear correlation between far-infrared and (sub)-mm fluxes. We argue that the link results from the combination of the stellar mass-luminosity relation and a scaling between disk mass and stellar mass. We find strong evidence of dust settling to the disk midplane. The spectral slopes between near- and far-infrared are mostly between $-0.5$ and $-1.2$ in our sample, comparable to more massive T Tauri stars, which may imply that the disk shapes are similar as well, though highly-flared disks are rare among brown dwarfs. We find that dust temperatures in the range of 7-15 K, calculated with $T\approx25\,(L/L_\odot)^{0.25}$ K, are appropriate for deriving disk masses from (sub)-mm fluxes for these low luminosity objects. About half of our sample hosts disks with at least one Jupiter mass, confirming that many brown dwarfs harbour sufficient material for the formation of Earth-mass planets in their midst.

description: We investigate the evolution of the Fermi surfaces and electronic interactions across the nematic phase transition in single crystals of FeSe1-xSx using Shubnikov-de Haas oscillations in high magnetic fields up to 45 tesla in the low temperature regime. The unusually small and strongly elongated Fermi surface of FeSe increases monotonically with chemical pressure, x, due to the suppression of the in-plane anisotropy except for the smallest orbit which suffers a Lifshitz-like transition once nematicity disappears. Even outside the nematic phase the Fermi surface continues to increase, in stark contrast to the reconstructed Fermi surface detected in FeSe under applied external pressure. We detect signatures of orbital-dependent quasiparticle mass renomalization suppressed for those orbits with dominant dxz=yz character, but unusually enhanced for those orbits with dominant dxy character. The lack of enhanced superconductivity outside the nematic phase in FeSe1-xSx suggest that nematicity may not play the essential role in enhancing Tc in these systems.

description: Coffee processing firms generate huge amount of solid wastes (coffee pulp and husk). Because of their abundance, chemical composition and physical characteristics, these residues should be handled in an appropriate way in order to avoid environmental impact as these wastes are easily dumped in to water bodies and unsanitary landfills due to their threat to the environment. Hence, this work was undertaken to transform these waste to bio-fertilizer using windrow composting technique with the intention to alleviate environmental impacts while to produce soil conditioner. In this study, the samples were placed in (6*3) treatments in RCBD in which 6 is the treatment and 3 is the replication. coffee pulp + coffee husk (pile 1), coffee pulp + coffee husk + cow dung (pile 2), coffee pulp + coffee husk + khat waste (pile 3), coffee pulp + coffee husk + cow dung + khat waste (pile 4), coffee pulp + cow dung (pile 5) and coffee husk + cow dung (pile 6) were used to prepare compost. The compost base area was 1m2 and 1m long (1m3in volume), above 20cm height bricks bed with the composting material in layers till the height of the piles become 1m long. Essential parameters were measured during the 80 day composting. Samples were collected on days 0, 45, 80 for Physico-chemical analysis. The compost maturity tests (germination and plant bioassay) were conducted using maize (BH540). The mean physicochemical results of matured compost found within the range of acceptable limits set by most countries guidelines except total potassium content which is out of the range recommended by many countries. Mean range specific values of pH, EC, %MC, OM, TKN, TP, K and C/N ratios for matured compost were:7.85-8.2, 2.66-4.4 dS/m, 39-49.6%, 39-42.7%, 1.28-2.06%, 0.25-1.02%,0.25-1.48 and 11-20.8 respectively. While a germination index of 100%, 125%, 121%, 150%, 112.5% and 118.75% was obtained respectively which depicted the compost maturity. Parameters like OC, OM, and C/N ratio decreases throughout the composting period while other parameters like pH, EC, and plant macronutrients TN, TP and TK increases as composting process progressed till maturity. Comparing the compost samples, the physic-chemical characteristics, germination and plant bio-assay the compost produced by coffee residue with other organic amendment has high nutrient value which can be used effectively as bio-compost. Key words: coffee residue, composting, compost quality, macronutrient and Germination Index
Labor on Display: The Exhibition of U.S. Art Objects and the Museum Labor Unionization Movement

description: While museums are public-facing institutions, they are also workplaces. Recently, there has been a renewed push toward labor unionization in the United States from workers both outside and inside museums. In consideration of the current bourgeois-influenced interpretation of art objects, the museum’s history of barring people of lower economic classes from its collections, and the current museum workplace environment, a common thread of labor emerges. This paper investigates the relationship between museum labor in the United States and the Marxist art historical interpretation of labor in art objects.
