Abstract:

In augustus 2021 verscheen onder de titel Omwille van fatsoen: De staat van menswaardige zorg een doorwrochte studie naar wat de auteur op de achterflap “de risico’s van de ‘institutionele vernedering’ in de Nederlandse verzorgingsstaat” noemt. Willemijn van der Zwaard schrijft in haar proefschrift verwonderd te zijn over “het gemak waarmee politiek en beleid opvattingen over een menswaardig bestaan institutionaliseren” en stelt dat de Nederlandse verzorgingsstaat de menselijke waardigheid, die zij voor iedereen wil garanderen, onder druk zet. Waar zij de eerste these onderbouwt met een brede en kritische analyse van Nederlandse wetgeving op het terrein van de verzorgingsstaat, wordt de tweede geïllustreerd met de uitkomsten van een observationele studie van de werkzaamheden van een buurtteam in Utrecht.

Abstract:

PURPOSE/THESIS: The main point that we want to emphasize in this study is that research in the field of knowledge organization in Romania over the last twenty years is unequally distributed among different professional categories ranging from library and Information science faculty members, library professionals, software tools developers to independent researchers. The specific situation of library and Information science functioning as a university department in Romania with an interruption of 20 years (1970-1990) affected the overall situation of scientific research in the specific fields associated with this discipline. APPROACH/METHODS: The study covers three stages: data collection, data recording and data interpretation. RESULTS AND CONCLUSIONS: The primary outcomes of the scientific research activities in question are publications (books, book chapters and journal articles). Given this, our interest will be directed towards the analysis to what extent research and publications have made an impact on the evolution of Romanian libraries over this twenty years span.

Full text

Abstract:

We review the magneto-structural properties of electron–electron correlated quasi-one- dimensional (1D) molecular organics. These weakly localized quarter-filled metallic-like systems with pronounced spin 1/2 antiferromagnetic (AF) interactions in stack direction exhibit a spin charge decoupling where magnetoelastic coupling picks up spin 1/2 to pair into S = 0 singlet dimers. This is well illustrated by the observation of a spin-Peierls (SP) instability in the (TMTTF)2X Fabre salts and related salts with the o-DMTTF donor. These instabilities are revealed by the formation of a pseudo-gap in the spin degrees of freedom triggered by the development of SP structural correlations. The divergence of these 1D fluctuations, together with the interchain coupling, drive a 3D-SP ground state. More surprisingly, we show that the Per2-M(mnt)2 system, undergoing a Kondo coupling between the metallic Per stack and the dithiolate stack of localized AF coupled spin ½ (for M = Pd, Ni, Pt), enhances the SP instability. Then, we consider the zig-zag spin ladder DTTTF2-M(mnt)2 system, where unusual singlet ground state properties are due to a combination of a 4kF charge localization effect in stack direction and a 2kF SP instability along the zig-zag ladder. Finally, we consider some specific features of correlated 1D systems concerning the coexistence of symmetrically different 4kF BOW and 4kF CDW orders in quarter-filled organics, and the nucleation of solitons in perturbed SP systems.

Abstract:

Zein, a subproduct of the food industry and a protein, possesses limited applications due to its high hydrophobic character. The objective of this research was to investigate the influence of homogenization pressure and cycles on the volumetric mean diameter (D4,3), span values, and Turbiscan Stability Index (TSI) using the response surface methodology for microfluidized emulsions containing zein as a unique stabilizer. Results showed that homogenization pressure seems to be the most influential parameter to obtain enhanced physical stability and droplet size distributions, with the optimum being 20,000 psi. Interestingly, the optimum number of cycles for volumetric diameter, span value, and TSI is not the same. Although a decrease of D4,3 with number of cycles is observed (optimum three cycles), this provokes an increase of span values (optimum one cycle) due to the recoalescence effect. Since physical stability is influenced by D4,3 and span, the minimum for TSI is observed at the middle level of the cycles (2 cycles). This work highlights that not only volumetric diameter, but also span value must be taken into consideration in order to obtain stable zein emulsions. In addition, this study wants to extend the limited knowledge about zein-based emulsions processed with a Microfluidizer device.

Full text

Abstract:

Single-walled carbon nanotube buckypapers (SWCNT-bps) coated with a metal–organic framework ZIF-8 layer were used as supports for the preparation of Pebax® 3533 TFC membranes by both phase inversion and spin coating techniques. Upon proper characterization of the materials by X-ray diffraction, IR spectroscopy, thermogravimetry and electron microscopy, the obtained membranes were tested in gas separation experiments with a 15:85 CO2/N2 mixture. These experiments proved that the ZIF-8 layer prevented from the penetration of the polymer selective film into the SWCNT-bp support, giving rise to a highly permeable selective membrane. The optimum membrane was achieved by the spin-coating method, with better permeation results than that prepared by the phase inversion method, obtaining a CO2 permeance of 566 GPU together with a CO2/N2 selectivity of 20.9.

Abstract:

The membrane-based gas separation is well-suited for the recovery of hydrocarbons from nitrogen-rich exhaust gases. However, the separation performance of the existing polymeric membranes was insufficient. In this study, zeolitic imidazolate framework-67 (ZIF-67) was synthesized and then incorporated into polydimethylsiloxane (PDMS) to prepare ZIF-67/PDMS mixed matrix membranes via the spin-coating method. The resultant ZIF-67 and membranes were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, and scanning electron microscope. The C3H6/N2 (20:80 vol) mixed gas separation tests indicated that the ZIF-67/PDMS membranes achieved the higher C3H6/N2 separation factor but the lower C3H6 permeance in contrast with pure PDMS membrane. At the ZIF-67 loading of 5 wt%, the membrane displayed the optimal separation factor of 16.5 with comparable C3H6 permeance of 86.9 GPU. Besides, the relatively low operating temperature and pressure were advantageous to gaining good gas separation performance.

Our theoretical study reveals the dependence of quantum conductance of Au-Co nanowires on their atomic structure. The results show the emergence of spin-filter state in one-dimensional Au-Co bimetallic nanowires. We found the existence of two transmission regime in Au-Co nanowires with low and high conductivity 1G0 and 2G0 for “zig-zag” and linear nanowire correspondingly. The study of transmission spectra of Au-Co nanowires reveals the control capability of spin transport regime by changing of bias voltage between bulk electrodes.

The calculations performed using thetight bindingapproach show the existence of quasi-degenerate orbitals located around the Fermi level, thus suggesting the importance of high-qualityab initiomethods, capable of a correct description of the nondynamical correlation. Such approaches (Complete Active Space SCF and Multireference Perturbation Theory calculations) were used in order to get accurate ground and nearest excited-state energies, along with the corresponding spin multiplicities.

Abstract:

Atthe first stage, the structureof theZnSe crystal doped with chromium atoms (ZnCrSe)has been found by optimization procedure. At the second stage, the electronic properties of this material have been evaluated within the two approaches. The exchange-correlation functionals used here are based on the generalized gradient approximation (GGA) and the hybrid functional PBE0. The GGA approach provides the metallic state for electrons with the spin up, and for opposite spin orientation the material ZnCrSe bahaves as semiconductor, with the band gap of 2.48 eV. The hybrid functional approach also gives a gapless state for a spin up electron states, and for a spin down it provides the forbidden gap value of 2.39 eV. The magnetic moment of the unit cell, found with the two functionals, is the same and equals to 4 Bμ(Bohr magnetons). So, the calculations with the two exchange-correlation functionals provide the prediction of half-metallic properties of the ZnCrSe material, which is an interesting candidate for spintronic applications.

Abstract:

Spin-polarized electron transport through a zigzag zinc oxide nanoribbon (ZnONR) has been studied using first-principles transport simulations. Ribbons without edges passivated show 100% spin polarization at small bias voltage independently of width. The ribbons with edge zinc atoms passivated maintain absolute spin-filtering effect in much larger bias region. The results demonstrate that zigzag ZnONRs act as perfect spin-filters in the absence of magnetic electrodes and external fields.

Full text

Abstract:

Abstract The article depicts the intense and at times unpredictable fable transfer in eighteenth-century Europe by tracing the source text of one of the most acclaimed works in Swedish fable history, Anna Maria Lenngren’s “Björndansen” [The dance of the bear]. This verse fable, published in Stockholms Posten in 1799 and bringing questions of literary quality and literary criticism into focus, was classified by the poet herself as “Original.” Twentieth-century scholars have identified a prose fable, “Björnen, Apan och Swinet” [The bear, the ape, and the swine], printed in the same daily paper in 1784 and translated from Spanish, as her probable source text. Eagerness to safeguard the poetical autonomy of Lenngren seems, though, to have restrained scholars from trying to find the Spanish original of the prose translation or to detect its author. Following the trails of French and German renderings of the Spanish fable about the dancing bear, the article demonstrates that “Björndansen” is a skilful Swedish recasting of “El Oso, la Mona y el Cerdo” [The bear, the ape, and the swine], one of the 67 verse fables in Tomás de Iriarte’s innovative Fábulas literarias (1782), a collection presenting a neoclassical poetics in the form of fable. Placing “Björndansen” within this larger international fable historical context, the article also manages, by means of comparative analysis, to throw new light on the literary devices of the Swedish masterpiece.

Full text

Abstract:

The inertial mass of a Fermion shows up as chiral cross-coupling in its Dirac system. No scalar term can invariantly couple left and right chirality fields; the Dirac matrices must be spin tensors of mixed chirality. We show how such tensor couplings could arise from nonlinear mixing of four spinor fields, two representing the local electron fields and two inertial spinor fields sourced in the distant masses. We thus give a model that implements Mach's principle. Following Mendel Sachs,1 we let the inertial spinors factor the moving spacetime tetrads qα(x) and [Formula: see text] that appear in the Dirac operator. The inertial spinors do more than set the spacetime "stage;" they are players in the chiral dynamics. Specifically, we show how the massive Dirac system arises as the envelope modulation equations coupling left and right chirality electron fields on a Friedmann universe via nonlinear "spin gratings" with the inertial spinor fields. These gratings implement Penrose's "mass-scatterings," which keep the null zig-zags of the bispinor wave function confined to a timelike world tube. Local perturbations to the inertial spinor fields appear in the Dirac system as Abelian and non-Abelian vector potentials.

The morphology of the first three zoeal stages of Hippolyte leptocerus (Heller, 1863) are described and illustrated in detail from laboratory-hatched material. The ovigerous females were collected on the Alfacs Bay, Ebro Delta, Spain (Western Mediterranean). The early larval stages (ZI, ZII, ZIII) showed the anterolateral margin of carapace with denticulations, a median tubercle behind rostrum, scaphocerite segmented distally (only ZI and ZII), exopodal seta at the maxillule and pleonite 5 with a pair of dorsolateral spines. The morphology of the first three zoeal stages of H. leptocerus is typical of species with an extended larval development. Morphological characteristics of the genus Hippolyte are discussed.

Full text

Abstract:

In this paper, inspired by origami structures, we offer a very simple tuning method to overcome the limitations of general elastic metasurfaces, where only a certain functionality at a certain frequency range can be achieved, by designing a reflective metasurface based on foldable/deployable zig-zag structures. By utilizing peg/screw connections, the folding angles of the zig-zag structures can be easily tuned while also being fixable. By tuning the folding angle, the subunit of the zig-zag metasurface can cover a 2π phase shift span and the phase shift can be tuned continuously, and almost linearly, with respect to the folding angle. With a simple folding motion, the tunable reflective metasurface can steer reflected flexural waves in different directions and focus-reflected flexural waves with different focal distances. In addition to demonstrating tunable performance, the mechanism that associates the changing speed of the phase shift is explained. The proposed tunable zig-zag elastic metasurface provides a new way to design reconfigurable metamaterials/metasurfaces.

Abstract:

Zinc Oxide thin films have been deposited on glass substrates at different spin rate by sol-gel spin coating method. XRD measurement of the ZnO films confirms the Wurtzite hexagonal phase with the preferred orientation along the C-axis (002) plane. The other characteristic orientations (100) and (101) have also been observed. The average crystallite size evaluated from the XRD data lies between 5 nm and 20 nm. The crystallographic parameters viz., lattice constants, mean crystalline size, dislocation density, texture coefficient and standard deviation have been calculated from the XRD data. The estimated texture coefficient indicates the oriented overgrowth of (002) plane for the ZnO films spin coated up to the spin rate 3500 rpm. ZnO thinfilm spin coated at 4000 rpm and 3500 rpm shows maximum transmittance of 87.5% and 88.5 % respectively at 850 nm. The measured direct band gap energy of the ZnO films coated at different spin rates varies between 3 eV and 3.3 eV. The grain size observed from the microstructure of AFM is around 50 nm and this indicates the aggregation of nanosize cryatallites. The effect of spin rate on the structural, optical and surface properties of the spin coated ZnO thinfilms have been investigated and reported.

Abstract:

De span of control van afdelingsmanagers verschilt gemiddeld een factor twee tussen verschillende medische afdelingen van drie vergelijkbare, grote algemene ziekenhuizen. Het verschil is terug te voeren op het type afdeling. De span of control kan volgens de organisatietheorie afhangen van vier clusters van oorzaken: de invloed van de manager, de afdelingsorganisatie, de kenmerken van de ondergeschikten en de aard van het werk. Deze factoren verschillen echter niet zodanig in de onderzochte ziekenhuizen, dat zij een bevredigende verklaring kunnen bieden voor het gevonden verschil in span of control. De taakopvatting en professionele doelstellingen van de afdelingshoofden bieden hiervoor een beter aanknopingspunt. Wij noemen dit een bedrijfspolitieke verklaring.

Abstract:

The study shows the first results of the column-integrated water vapor retrieved by the new ZEN-R52 radiometer. This new radiometer has been specifically designed to monitor aerosols and atmospheric water vapor with a high degree of autonomy and robustness in order to allow the expansion of the observations of these parameters to remote desert areas from ground-based platforms. The ZEN-R52 device shows substantial improvements compared to the previous ZEN-R41 prototype: a smaller field of view, an increased signal-to-noise ratio, better stray light rejection, and an additional channel (940 nm) for precipitable water vapor (PWV) retrieval. PWV is inferred from the ZEN-R52 Zenith Sky Radiance (ZSR) measurements using a lookup table (LUT) methodology. The improvement of the new ZEN-R52 in terms of ZSR was verified by means of a comparison with the ZEN-R41, and with the Aerosol Robotic Network (AERONET) Cimel CE318 (CE318-AERONET) at Izaña Observatory, a Global Atmosphere Watch (GAW) high mountain station (Tenerife, Canary Islands, Spain), over a 10-month period (August 2017 to June 2018). ZEN-R52 aerosol optical depth (AOD) was extracted by means of the ZEN–AOD–LUT method with an uncertainty of ±0.01 ± 0.13*AOD. ZEN-R52 PWV extracted using a new LUT technique was compared with quasi-simultaneous (±30 s) Fourier Transform Infrared (FTIR) spectrometer measurements as reference. A good agreement was found between the two instruments (PWV means a relative difference of 9.1% and an uncertainty of ±0.089 cm or ±0.036 + 0.061*PWV for PWV <1 cm). This comparison analysis was extended using two PWV datasets from the same CE318 reference instrument at Izaña Observatory: one obtained from AERONET (CE318-AERONET), and another one using a specific calibration of the 940-nm channel performed in this work at Izaña Atmospheric Research Center Observatory (CE318-IARC), which improves the PWV product.

Abstract:

Abstract As shown in recent experiments (Lienhard et al 2020 Phys. Rev. X 10 021031), spin–orbit coupling in systems of Rydberg atoms can give rise to density-dependent Peierls phases in second-order hoppings of Rydberg spin excitations and nearest-neighbor repulsion. We here study theoretically a one-dimensional zig-zag ladder system of such spin–orbit coupled Rydberg atoms at half filling. The second-order hopping is shown to be associated with an effective gauge field, which in mean-field approximation is static and homogeneous. Beyond the mean-field level the gauge potential attains a transverse quantum component whose amplitude is dynamical and linked to density modulations. We here study the effects of this to the possible ground-state phases of the system. In a phase where strong repulsion leads to a density wave, we find that as a consequence of the induced quantum gauge field a regular pattern of current vortices is formed. However also in the absence of density–density interactions the quantum gauge field attains a non-vanishing amplitude. Above a certain critical strength of the second-order hopping the energy gain due to gauge-field induced transport overcomes the energy cost from the associated build-up of density modulations leading to a spontaneous generation of the quantum gauge field.

Abstract:

Films of polyaniline and polyaniline–ZnO composites were synthesized by spin coating. The spin coated films were deposited over glass substrate. In order to confirm the dispersion quality and the size of the dispersed ZnO, Transmission electron microscopy was done. The TEM images show that ZnO nanoparticles were spherical in shape. Dark imaging mode confirmed these particles in solid phase and revealed the uniform distribution of the particles in the PANI matrix. The absorption peaks in FTIR spectra of PANI–ZnO composite film were found to shift to higher wave number when compared with pure PANI. The observed shifts were attributed to the interaction between the ZnO particle and PANI molecular chains. A change in the value of lattice parameter of ZnO as confirmed through the X ray diffraction method in the composite indicated the presence of interaction between ZnO particles and matrix. The dielectric study of PANI and PANI–ZnO composites demonstrated a significant decrease in the value of dielectric constant after the incorporation of the ZnO nanoparticles in the polymer matrix.

Abstract:

Erythrocyte ghosts, prepared from rats fed zinc-deficient diets, were analyzed for the mobility of membrane proteins by electron spin resonance spectroscopy of the sulfhydryl-binding spin probe, 4-maleimido-2,2,6,6-tetramethylpiperidine-N-oxyl. Compared with erythrocyte membranes from rats fed zinc-adequate diets ad libitum or pair-fed, erythrocyte membranes from zinc-deficient rats had a significantly increased ratio of weakly immobilized to strongly immobilized probe-binding proteins. This suggests that dietary zinc deficiency causes a conformational change in erythrocyte membrane proteins. Dietary zinc deficiency did not significantly affect N-ethylmaleimide (NEM)-induced thermal sensitivity or NEM-induced mechanical fragility in rat erythrocytes; however, the addition of zinc in vitro to red cells significantly inhibits NEM-induced mechanical fragility.

Abstract:

Two new compounds of general formula [M(N3)2(dmbpy)] in which dmbpy = 5,5′-dimethyl-2,2′-bipyridine, and M = Mn(II) or Co(II), have been solvothermally synthesized and characterized structurally and magnetically. The structures consist of zig-zag polymeric chains with alternating bis-µ(azide-N1)2M and bis-µ(azide-N1,N3)2M units in which the cis-octahedrally based coordination geometry is completed by the N,N’-chelating ligand dmbpy. The molecular structures are basically the same for each metal. The Mn(II) compound has a slightly different packing mode compared to the Co(II) compound, resulting from their different space groups. Interestingly, relatively weak interchain interactions are present in both compounds and this originates from π–π stacking between the dmbpy rings. The magnetic properties of both compounds have been investigated down to 2 K. The measurements indicate that the manganese compound shows spin-canted antiferromagnetic ordering with a Néel temperature of TN = 3.4 K and further, a field-induced magnetic transition of metamagnetism at temperatures below the TN. This finding affords the first example of an 1D Mn(II) compound with alternating double end-on (EO) and double end-to-end (EE) azido-bridged ligands, showing the coexistence of spin canting and metamagnetism. The cobalt compound shows a weak ferromagnetism resulting from a spin-canted antiferromagnetism and long-range magnetic ordering with a critical temperature, TC = 16.2 K.

Abstract:

Abstract Along with the great interest in two-dimensional elemental materials that has emerged in recent years, atomically thin layers of bismuth have attracted attention due to physical properties on account of a strong spin–orbit coupling. Thickness dependent electronic band structure must be explored over the whole Brillouin zone in order to further explore their topological electronic properties. The anisotropic band structures along zig-zag and armchair directions of α-bismuthene (α-Bi) were resolved using the two-dimensional mapping of angle-resolved photoemission spectra. An increase in the number of layers from 1- to 2-bilayers (BLs) shifts the top of a hole band on Γ ¯ – X ¯ 1 line to high wavenumber regions. Subsequently, an electron pocket on Γ ¯ – X ¯ 1 line and a hole pocket centred at Γ ¯ point appears in the 3 BL α-Bi. Gapless Dirac-cone features with a large anisotropy were clearly resolved on X ¯ 2 point in the 1-BL and 2-BL α-Bi, which can be attributed to the strong spin–orbit coupling and protection by the nonsymmorphic symmetry of the α-Bi lattice.

Abstract:

We present the synthesis of ZnO nanostructures grown by the hydrothermal method using the rapid microwave heating process. First, 10 mM solutions of zinc acetate dihydrate and 1-propanol were three cycles spin coated on glass substrates at 2000 rpm by 70 s, 90 s and 90 s, respectively. Second, nanostructures were then grown by dipping the substrates in a solution of zinc nitrate hexahydrate, polyethyleneimine (PEI), hexamethylenetetramine and ammonia. The hydrothermal process were carried out with a commercial microwave at 300, and 600 W power settings during 20 min. The structural and morphological properties were investigated using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The influence of the ammonium concentration in the morphology of the nanostructures was analyzed.Keywords: ZnO, nanostructures, XRD, SEM, spin coating, ammonium, hydrothermal process.

Abstract:

In this work, the effect of different production techniques was evaluated on the physical and antioxidant properties of bio-based packaging intended to prevent the premature oxidation of packaged foods. Spent coffee ground extract, rich in antioxidant molecules, obtained through high pressure and temperature extraction, was loaded on zein polymeric matrices. The techniques adopted in this work are particularly suitable due to their mild conditions to produce active packaging completely based on natural compounds: electrospinning, solvent casting, and spin coating. The novelty of this work lay in the investigation of the dependance of the properties of active packaging on the adopted production techniques; the results clearly indicated a strong dependence of the features of the films obtained by different production processes. Indeed, spin coated samples exhibited the best oxygen barrier properties, while a higher tensile strength was obtained for the casted samples, and the fastest release of active compounds was provided by electrospun mats. The films produced with different methods had different physical properties and the release of extract bioactive compounds can be tunable by varying the production technique, dependent on the variable to be considered. The products developed offer an alternative to traditional packaging solutions, being more eco-sustainable and promoting waste valorization.
