OCENA ZJAWISKA TWORZENIA SIĘ HYDRATÓW W WARUNKACH NIEUSTALONEGO

This work presents a transient, non-isothermal compressible gas flow model that is combined with a hydrate phase equilibrium model. It enables, to determine whether hydrates could form under existing operating conditions in natural gas pipelines. In particular, to determine the time and location at which the natural gas enters the hydrate formation region. The gas flow is described by a set of partial differential equations resulting from the conservation of mass, momentum, and energy. Real gas effects are determined by the predictive Soave-Redlich-Kwong group contribution method. By means of statistical mechanics, the hydrate model is formulated combined with classical thermodynamics of phase equilibria for systems that contain water and both hydrate forming and non-hydrate forming gases as function of pressure, temperature, and gas composition. To demonstrate the applicability a case study is conducted.
Examining the optical intensity and magnetic field expansion factor in the open magnetic field regions associated with coronal holes

Abstract Coronal holes can be identified as the darkest regions in EUV or soft X-ray images with predominantly unipolar magnetic fields (LIRs) or as the regions with open magnetic fields (OMF). Our study reveals that only 12% of OMF regions are coincident with LIRs. The aim of this study is to investigate the conditions that affect the EUV intensity of OMF regions. Our results indicate that the EUV intensity and the magnetic field expansion factor of the OMF regions are weakly positively correlated when plotted in logarithmic scale, and that the bright OMF regions are likely to locate inside or next to the regions with closed field lines. We empirically determined a linear relationship between the expansion factor and the EUV intensity. The relationship is demonstrated to improve the consistency from 12% to 23%. The results have been published in Astrophysical Journal (Huang et al. 2019).
The AGN-galaxy connection: Low-redshift benchmark & lessons learnt

Abstract Several scenarios have been proposed to describe the physical connection between galaxies and their central active galactic nuclei (AGN). This connection could act on a range of spatial scales and vary across cosmic time. In these proceedings, we consider black hole and galaxy growth and whether that growth is affected by AGN feedback both based on statistical approaches – which reveal general population trends – and based on an individual case study – which gives us a more detailed insight on the physical processes at play. For the statistical approach, we showcase a low-redshift (0.04 < z < 0.2) SDSS sample with AGN classification based on a combination of emission-line diagnostic diagrams, and for which we account for sample selection by using a V/Vmax approach. The trends on the star formation rate - stellar mass (SFR – M*) plane suggest that the most likely connection is a common gas reservoir for star formation and AGN, and that they both decline as the gas reservoir is consumed. The trends established at low-redshift could act as a local benchmark against which to compare higher redshift studies. As a complementary approach, we use a detailed case study of a nearby AGN host with integral field spectroscopy from the VLT/MUSE instrument in order to spatially resolve the interplay between AGN feedback and the host galaxy. We find that the galaxy substructure likely plays a role by collimating and/or obscuring the outflows and radiation from the central engine. Ongoing and future work with 3D spectroscopy will enable us to learn more about galaxy and black hole coevolution. Lastly, we briefly discuss lessons learnt from both approaches.
Behaviour of radicals on interstellar dust analogues

Abstract Surface reactions of radicals play important roles in the formation of complex molecules on interstellar dust grains. Under interstellar conditions, because the coverage of adsorbates on dust is significantly low, surface reactions are often limited by precedent processes, namely, the adsorption and diffusion of reactants. Therefore, to appropriately incorporate dust surface reactions into chemical models, information on the adsorption and diffusion of radicals is crucial. However, it is not easy to follow the behaviour of radicals on surfaces by conventional experimental methods. To monitor radicals on interstellar dust analogues, we have recently succeeded in applying a combination of photostimulated desorption and resonance-enhanced multiphoton ionization methods. In this paper, we briefly review our recent experiments for clarifying radical behaviour on water ice, pure solid CO and diamond-like carbon.

Semi-empirical 2D model of the solar corona and solar wind using solar eclipse images: Progress report

Abstract We present white light images of the Sun's corona acquired during the total Solar Eclipses on August 21, 2017 in mountains north of Boise Idaho USA and on July 2, 2019 south of Copiapo Chile. In both cases the viewing was excellent, altitudes ∼ 1200 m and relative humidity ∼ 10. We used an Orion equatorial reflecting telescope with 203 mm diameter aperture and 1000 mm focal length for f4.9 optics. A computer-controlled Canon EOS Rebel T3i digital camera was used. We plan to use our 2019 eclipse images for analysis since the Sun is near solar minimum so 2D steady state MHD equations can be used. We present a plan to process the images and convert them into a 2D empirical model of electron density and magnetic field in radial distance and co-latitude, from which 2D maps of flow velocity, effective temperature and effective heat flux can be computed.
Porcine-derived acellular dermal collagen matrix and enamel matrix derivative for the treatment of infrabony defect in the esthetic area

This case report describes a modified connective tissue graft wall technique with enamel matrix derivative proposed to treat vertical bony defects. The surgical procedure consisted of a coronally advanced flap with a porcine-derived acellular dermal matrix placed below, acting as a buccal soft tissue wall of the bony defect. The patient showed a bony defect between #12 and #13 with horizontal bone loss and a deep infrabony component at the mesial area of the canine. At one year after surgery, the position of the interdental papilla and the clinical attachment level gain were improved along with radiographic bone defect fill.
Improved Harmonic Incompatibility Removal for Susceptibility Mapping via Reduction of Basis Mismatch

In quantitative susceptibility mapping (QSM), the background ﬁeld removal is an es-sential data acquisition step because it has a signiﬁcant eﬀect on the restoration quality by generating a harmonic incompatibility in the measured local ﬁeld data. Even though the sparsity based ﬁrst generation harmonic incompatibility removal (1GHIRE) model has achieved the performance gain over the traditional approaches, the 1GHIRE model has to be further improved as there is a basis mismatch underlying in numerically solving Poisson’s equation for the background removal. In this paper, we propose the second generation harmonic incompatibility removal (2GHIRE) model to reduce a basis mismatch, inspired by the balanced approach in the tight frame based image restoration. Experimental results shows the superiority of the proposed 2GHIRE model both in the restoration qualities and the computational eﬃciency.
Dicamba emissions under field conditions as affected by surface condition – CORRIGENDUM

The evolution and widespread distribution of glyphosate-resistant broadleaf weed species catalyzed the introduction of dicamba-resistant crops that allow this herbicide to be applied POST to soybean and cotton. Applications of dicamba that are most cited for off-target movement have occurred in June and July in many states when weeds are often in high densities and at least 10 cm or taller at the time of application. For registration purposes, most field studies examining pesticide emissions are conducted using bare ground or very small plants. Research was conducted in Knoxville, TN, in the summer of 2017, 2018, and 2019 to examine the effect of application surface (tilled soil, dead plants, green plants) on dicamba emissions under field conditions. Dicamba emissions after application were affected by the treated surface in all years, with the order from least to most emissions being dead plants < tilled soil < green plant material. In fact, dicamba emissions were >300% when applied to green plants compared to other surfaces. These findings suggest that dicamba applicationsmade to bare ground will likely underestimate what may occur under normal field use conditions when POST applications are made and the crop canopy or weed groundcover is nearly 100% green material. A potential change to enhance the accuracy of current environmental simulation models would be to increase the theoretical findings to allow for the effect of green plant material on dicamba emissions under field conditions.
Introduction

Museums have traditionally been understood as places where carefully selected objects are categorized and put on display so that they can be known through observation. So-called ‘world-museums’, such as the British Museum, were designed to provide the public with access to the wider world through the knowledge they could acquire simply by observing the objects put forward for their inspection. This understanding of what museums do has been increasingly called into question due to changing views of knowledge-acquisition. New understandings of museums are emerging that seek to be responsive to more complex epistemological theories, and philosophers, as evidenced by the essays in this volume, are taking a lively interest in this development. As the essays in this volume further show, specific aspects of museum practices—especially concerning collection and curation, as well as exhibition—also invite philosophical scrutiny.
Approaches to form-factors of higher spin Heisenberg chains

In this thesis we apply the vertex operator approach of Jimbo and Miwa to higher spin Heisenberg chains with the aim of computing the form-factors of these quantum integrable models. The work is motivated by the relation of the form-factors to the dynamical structure factors of the model objects that are experimentally realisable and potential for comparison with real-world results. Using a one boson, one fermion free field realisation of Uq(ŝl2), in conjunction with a realisation for the fermionic contribution due to Shiraishi, we are able to give the formalism required to obtain explicit multiple integral expressions for the 2m-particle form-factors of the antiferromagnetic spin-1 Heisenberg chain. Using this novel boson-fermion-Shiraishi scheme, we are able to obtain single integral expressions for the two-spinon contribution to the S form-factor. We also consider a certain modification of a known q-Wakimoto bosonisation scheme for arbitrary spin and its relevance to the computation of higher spin form-factors. We consider the form of the resultant BRST relations and discuss simplifications arising through this approach, as well as the difficulties faced in obtaining integral expressions.

Assessing Utilisation and Expenditure on Long-Acting Insulin Analogues in Kenya; Findings and Implications for the Future

Prevalence rates for patients with diabetes mellitus are rising across countries including sub-Saharan African countries, which will continue. As a result, there are an increasing number of patients with insulin-dependent diabetes across sub-Saharan Africa including Kenya. Growing prevalence rates are increasing the costs of treating patients with diabetes enhanced by associated complications. These include both microvascular and macrovascular complications, with hypoglycaemia and generally poor control of diabetes contributing to the burden. Long-acting insulin analogues were developed to reduce rates of hypoglycaemia associated with insulin usage, including nocturnal hypoglycaemia, and improve adherence through improving patient convenience. As a result, they are now included in the Kenyan Essential Medicines List. However, long-acting insulin analogues are typically considerably more expensive than standard insulins limiting their use in practice, especially in countries such as Kenya with concerns with affordability even for standard insulins such as Mixtard®. Consequently, a need to ascertain current utilisation and expenditure patterns for the different insulins including long-acting insulin analogues across Kenya starting with leading referral hospitals. Research in Kenyatta National Hospital (KNH) showed growing use of insulin glargine reaching up to 3.4 to 3.6% of total insulin utilisation in 2019 and 2020. However, prescribing was limited by considerably higher prices (3.4 fold higher) than standard insulins on a defined daily dose basis. Considerably higher prices resulted in no utilisation of long-acting insulin analogues in another leading referral hospital in Kenya. Overall, appreciably lowering the prices of long-acting insulin analogues through instigating local production and other activities should increase their use benefiting patients and the healthcare system in Kenya and wider. These are considerations for the future.
Detailed characterisation of LINERs and retired galaxies in the local universe

Abstract We present a detailed characterisation of physical properties of low-ionization nuclear emission-line regions (LINERs) and retired galaxies (RGs) in the local universe for redshift range 0 < z < 0.4 and two subranges z < 0.4 and 0.1 < z < 0.4. Furthermore, we test the effectiveness of WHAN diagnostic diagram in separating the two populations. We used photometric data, public spectroscopic data and morphological classification from SDSS-DR8, MPA-JHU SDSS-DR8 catalogue and Galaxy Zoo survey, respectively. We studied the distribution of LINERs, RGs and AGN-LINERs in relation to luminosity, stellar mass, star formation rate (SFR), colour, and their location on the SFR-stellar mass and colour-stellar mass diagrams. We then studied the morphologies of both populations. Results have shown that for higher redshift range, AGN-LINERs have higher apparent g magnitude, SFRs and dominate on/above the main sequence (MS) of star formation compared to RGs. However, both populations have similar stellar mass and luminosity distributions at all redshift ranges hence suggesting a significant difference in terms of star formation of RGs and AGN-LINERs with redshift. However, larger and more complete samples of LINERs are needed from the future surveys (e.g., LSST) and missions (e.g., JWST) to study in more details the properties of RGs and AGN-LINERs and find alternative methods of separating the two populations, since using simply WHAN diagram from our study we do not find it to be effective for separating the two populations.
Clustering of galaxies around quasars at z ∼ 4

Abstract We conduct a survey for Lyman break galaxies (LBGs) and Lyman alpha emitters (LAEs) in the environs of six and 17 z ∼ 4 quasars respectively, probing scales of R≲9h−1Mpc. We detect an enhancement of galaxies (both LBGs and LAEs) in quasar fields, a positive and strong quasar-galaxy cross-correlation function, consistent with a power-law shape, and a strong galaxy auto-correlation function in quasar fields. The three mentioned results are all indicators that quasars trace massive dark matter halos in the early universe.
Experimental and Theoretical Thermodynamic Study of Distillable Ionic Liquid 1,5-Diazabicyclo[4.3.0]non-5-enium Acetate

A thermochemical study of the protic ionic liquid 1,5-diazabicyclo[4.3. 0]non-5-enium acetate ([DBNH][OAc]), a prospective cellulose solvent considered for the Ioncell-F process, was carried out. The heat capacities of 1,5-diazabicyclo[4.3. 0]non-5-ene (DBN) and [DBNH][OAc] were measured by differential scanning calorimetry (DSC) at 223–323 and 273–373 K temperature ranges, respectively. The enthalpies of fusion and synthesis reaction of [DBNH][OAc] were measured by DSC and reaction calorimetry, respectively. The gas-, liquid-, and solid-phase enthalpies of formation of [DBNH][OAc] and DBN were determined using calorimetric and computational methods. The enthalpy of vaporization of [DBNH][OAc] was estimated from the formation enthalpies. The activity coefficients at infinite dilution of 17 and the enthalpies of solution at infinite dilution of 25 organic solutes in [DBNH][OAc] were measured by gas chromatography and solution calorimetry methods, respectively. The obtained data will be used in the design and.
Development and characterization of heparin-immobilized polycaprolactone nanofibrous scaffolds for tissue engineering using gamma-irradiation

Polycaprolactone (PCL) has been considered a useful material for orthopedic devices and osseous implants because of its biocompatibility and bone-forming activity. However, PCL-based scaffolds have hydrophobic surfaces that reduce initial cell viability. In this study, we fabricated surface-modified PCL nanofibers for tissue engineering using radiation technology. We supplemented the hydrophilicity of the PCL nanofibers by introducing 2-aminoethyl methacrylate (AEMA) through gamma-irradiation and subsequently immobilized heparin onto the nanofibers using the EDC/NHS reaction. The SEM images show that there is almost no change in the morphology of nanofibers after radiation grafting of AEMA and heparin-immobilization onto PCL nanofibers. The surface properties of the scaffolds were characterized by ATR-FTIR, XPS, and fluorescamine staining in order to confirm the successful grafting of AEMA onto the PCL nanofibers. Immobilization of heparin was also confirmed by the amide I (1650 cm−1) and amide II group (1550 cm−1) from ATR-FTIR. The amounts of heparin were drastically increased on the AEMA–PCL nanofibers as revealed by TBO assay. The initial cell viability of hMSCs was significantly increased on the AEMA grafted nanofibers but grew slowly on heparin-immobilized nanofibers. The cumulative release of bone morphogenetic protein-2 (BMP-2) was slow and continuous onto the heparin-immobilized nanofibers (18.13 ± 3.87 μg mL−1) compared to PCL nanofibers (20.25 ± 1.45 μg mL−1). Therefore, heparin-immobilized nanofibers may be a good tool for tissue engineering applications using radiation technology.
A Review on Types of Vanadium Deposits and Process Mineralogical Characteristics

Because vanadium mainly exists as a trace element in minerals, vanadium deposit refers to a deposit capable of recovering vanadium from by-products rather than a reserve where vanadium-enriched minerals are locally concentrated. Vanadium deposits are largely divided into four types: VTM, SSV, shale-hosted vanadium, and vanadate deposits. VTM deposits, where vanadium is mostly present in magnetite, is embedded in mafic–ultramafic rocks. Ilmenite often forms exsolution lamellae or intergrowth in magnetite; therefore, it is impossible to upgrade the concentrate to a certain level or higher via further grinding. In-depth mineralogical characterization of ore minerals should be conducted to reduce the content of impurities such as Si, Al, Mg, and Ca in the concentrate. Based on this, subsequent cleaner stages can probably upgrade the vanadium concentrate.
Classification of radicular biomass and monitoring of litter in Pantanal and Cerrado Mato-Grossense

The quantification of root biomass and the assessment of its dynamics in forest ecosystems has been intensified due to its important role in carbon sequestration and storage and the possible consequences under climate change conditions. In general, biomass stocks between and within forest ecosystems are highly variable. It is necessary to study all the different components of vegetation, however, the vast majority of the works found in the literature, address only the biomass of the aerial part of the plants, with few studies involving the quantification of these stocks by the roots, in the different ecosystems. The present study objective quantify and classify a root biomass with a depth of 0 to 10 cm, and to monitor accumulated litter in the soil (litter pool), in two different regions, in the Pantanal (Acurizal) and in the Cerrado (Sensu stricto) Mato-Grossense. The root biomass was obtained by means of unformed soil samples (0-10 cm) and the roots were classified by diameter, with the aid of digital calipers, between thick (> 10 mm), medium (5-10 mm), slightly thin (2-5 mm) and fine (<2 mm). The samples collected monthly between August 2018 and July 2019. Was observed that in both areas, about 90% of the roots collected, were fine (<2 mm). The root density in Acurizal was on average 124.92 g/m2 and in Sensu stricto it was on average 57.5 g/m2. The difference in root density in the soil, between the two study areas, significant (p<0.05). However, there no significant difference in root density between the dry and wet periods in each area. The monthly average of litter pool in the area of Acurizal and Sensu stricto was, respectively: 526.52 g/m2 and 588.96 g/m2. In both areas, the accumulated litter was significantly different between periods of drought and precipitation.
Solar astrometry with planetary transits

Abstract Planetary transits are used to measure the solar radius since the beginning of the 18th century and are the most accurate direct method to measure potentially long-term variation in the solar size. Historical measures present a range of values dominated by systematic errors from different instruments and observers. Atmospheric seeing and black drop effect contribute as error sources for the precise timing of the planetary transit ground observations. Both Solar and Heliospheric Observatory (SOHO) and Solar Dynamics Observatory (SDO) made observations of planetary transits from space to derive the solar radius. The International Astronomical Union approved the resolution B3 in 2015, defining a nominal solar radius of precisely 695,700 km. In this work, we show that this value is off by more than 300 km, which is one order of magnitude higher than the error of the most recent solar radius observations.
