description: Background Iron (Fe) is traditionally supplemented in poultry and swine diets using inorganic forms (e.g. sulfates, oxides). However, research suggests that organic sources are more beneficial due to greater bioavailability. In this paper, we present results from four studies aimed at assessing ferric citrate (CI-FER™, Akeso Biomedical Inc., Burlington, MA, USA) as a safe and effective source of Fe for broilers and piglets. Methods A total of four studies were performed in Germany following standard farming practices for each species. One study in day-old broiler chicks and one study in weaned piglets were designed as target animal safety studies where animals were randomly allocated to one of three treatment groups: a negative control group, the proposed dose group and a multifold dose group. Broilers and pigs were fed the experimental diets for 35 and 42 days, respectively. In each study, average daily feed intake, average daily weight gain and feed conversion ratio were measured, and blood samples were taken at study end for routine biochemistry and haematology. The other two studies were designed to evaluate different sources of dietary Fe for weaned piglets bred and managed under standard farm conditions. All piglets received routine Fe injections (200 mg Fe dextran, intramuscular) on day 3 of age, as well as the experimental diets for 42 days. In both studies, performance parameters were measured. In one study, Fe digestibility and serum Fe, superoxide dismutase and haptoglobin were also measured. In all studies, the general health status of the animals was monitored daily and all culls and mortality recorded. Each study followed a complete randomised block design. Results In broilers, ferric citrate was well tolerated up to 2,000 mg/kg feed (×10 the recommended inclusion rate) and no adverse effects on growth, blood parameters or mortality were observed. In piglets, ferric citrate was well tolerated up to 5,000 mg/kg feed (×10 the recommended inclusion rate) with no adverse effects on growth, blood parameters or mortality. In addition, piglets fed ferric citrate performed significantly better than animals fed the negative control diet (containing only endogenous Fe) and those fed inorganic forms of Fe. Moreover, piglets fed ferric citrate demonstrated improved Fe digestibility and improved oxidative status. Altogether, these findings show that ferric citrate is a safe and easily digestible source of dietary Fe for broilers and piglets.

description: Το ερευνητικό ενδιαφέρον της εργασίας αυτής με θέμα «Το Μεγάλο μας Σπίτι ως χώρος κοινωνικοποίησης του μικρού παιδιού. Μια μελέτη περίπτωσης» επικεντρώνεται γύρω από την κοινωνική ανάπτυξη του μικρού παιδιού με σκοπό να διερευνηθεί η πορεία προς την κοινωνικοποίησή του. Κύριος στόχος είναι η μελέτη της ιδιαίτερης αυτής δομής ως χώρος πρώιμης κοινωνικοποίησης, προκειμένου να αναδειχθεί η συμβολή του χώρου, ο ρόλος των προσώπων υποδοχής και των συνοδών προσώπων στην πορεία της κοινωνικοποίησης του μικρού παιδιού καθώς και τη θέση που αυτό έχει μέσα στο ΜμΣ. Η θεωρητική προσέγγιση έγινε κυρίως μέσα από την ψυχαναλυτική οπτική καθώς αυτή αποτελεί το θεωρητικό υπόβαθρο της λειτουργίας του ΜμΣ. Μέσα από τη συμμετοχική παρατήρηση, τις καταγραφές και τη συνέντευξη από τα τρία πρόσωπα υποδοχής αναδείχθηκε η σημασία του χώρου και ο ενθαρρυντικός ρόλος των προσώπων υποδοχής στα πρώτα βήματα του παιδιού προς την κοινωνικοποίηση του. Στο ΜμΣ το παιδί αναγνωρίζεται ως υποκείμενο και ενθαρρύνεται να συναντήσει τον άλλον μέσα σε συνθήκες συναισθηματικής ασφάλειας που του εξασφαλίζει η παρουσία των γονιών του ή των οικείων ενηλίκων που το συνοδεύουν. Αυτοί μέσα σε ένα περιβάλλον που τους δίνει ασφάλεια και απουσιάζουν οι κοινωνικές νόρμες αναγνωρίζουν και ενθαρρύνουν την ανάγκη των παιδιών τους να συναντήσουν συνομήλικους τους και να κάνουν τα πρώτα τους κοινωνικά βήματα.

description: Questo lavoro di ricerca vuole essere una proposta di lavoro interdisciplinare che, seguendo le direttive promosse da HarmoS, metta in relazione la musica e l’educazione visiva, in particolare la pittura. L’obiettivo principale del percorso è verificare se la somministrazione di una serie di lezioni relative alle espressioni artistiche del Novecento, che mettano a confronto musica e arte figurativa, possa accrescere motivazione, interesse e curiosità negli alunni. A questo scopo, sono state scelte due classi di terza media: una di queste ha seguito un percorso interdisciplinare mentre l’altra si è limitata a seguire lezioni che si basassero esclusivamente sugli aspetti musicali. Prima di sottoporre le lezioni, entrambe le classi hanno compilato un questionario preliminare che verificasse i pregiudizi ed i prerequisiti dei ragazzi. Sulla base dei risultati del primo sondaggio è stato programmato e svolto un percorso didattico che mirava a presentare Impressionismo, Espressionismo, Futurismo e Minimalismo, sfruttando quattro diversi approcci didattici. Con un questionario finale si è potuto rilevare quanto un confronto tra musica e pittura possa risultare efficace: i risultati emersi hanno infatti dimostrato che tutti gli alunni che hanno seguito il percorso interdisciplinare hanno raggiunto gli obiettivi minimi ed hanno sviluppato maggiormente il loro sapere globale, con un accrescimento d’interesse e motivazione verso la storia della musica.

description: We give a numerical characterization of mutual orthogonality (that is, complementarity) for subalgebras. In order to give such a characterization for mutually orthogonal subalgebras $A$ and $B$ of the $k \times k$ matrix algebra $M_k(\mathbb{C})$, where $A$ and $B$ are isomorphic to some $M_n(\mathbb{C})$ $(n \leq k)$, we consider a density matrix which is induced from the pair $\{A, B\}$. We show that $A$ and $B$ are mutually orthogonal if and only if the von Neumann entropy of the density matrix is the maximum value $2\log n$, which is the logarithm of the dimension of the subfactors.

description: We study the response of a Hodgkin-Huxley neuron stimulated by a periodic sequence of conductance pulses arriving through the synapse in the high frequency regime. In addition to the usual excitation threshold there is a smooth crossover from the firing to the silent regime for increasing pulse amplitude $g_{syn}$. The amplitude of the voltage spikes decreases approximately linearly with $g_{syn}$. In some regions of parameter space the response is irregular, probably chaotic. In the chaotic regime between the mode-locked regions 3:1 and 2:1 near the lower excitation threshold the output interspike interval histogram (ISIH) undergoes a sharp transition. If the driving period is below the critical value, $T_i < T^*$, the output histogram contains only odd multiples of $T_i$. For $T_i > T^*$ even multiples of $T_i$ also appear in the histogram, starting from the largest values. Near $T^*$ the ISIH scales logarithmically on both sides of the transition. The coefficient of variation of ISIH has a cusp singularity at $T^*$. The average response period has a maximum slightly above $T^*$. Near the excitation threshold in the chaotic regime the average firing rate rises sublinearly from frequencies of order 1 Hz.

description: One of the leading issues in high-$\rm T_c$ copper oxide superconductors is the origin of the pseudogap phase in the underdoped regime of their phase diagram. Using polarized neutron diffraction, a novel magnetic order has been identified as an hidden order parameter of the pseudogap as the transition temperature corresponds to what is expected for the pseudogap. The observed magnetic order preserves translational symmetry as predicted for orbital moments in the circulating current theory. Being now reported in three different cuprates familles, it appears as a universal phenomenon whatever the crystal structure (with single CuO$_2$ layer or bilayer per unit cell). To date, it is the first direct evidence of an hidden order parameter characterizing the pseudogap phase of high-$\rm T_c$ cuprates.

description: The neurotransmitter GABA and its receptors assume essential functions during fetal and postnatal brain development. The last trimester of a human pregnancy and early postnatal life involves a vulnerable period of brain development. In the second half of gestation, there is a developmental shift from depolarizing to hyperpolarizing in the GABAergic system, which might be disturbed by preterm birth. Alterations of the postnatal GABA shift are associated with several neurodevelopmental disorders. In this in vivo study, we investigated neurogenesis in the dentate gyrus (DG) in response to daily administration of pharmacological GABA(A) (DMCM) and GABA(B) (CGP 35348) receptor inhibitors to newborn rats. Six-day-old Wistar rats (P6) were daily injected (i.p.) to postnatal day 11 (P11) with DMCM, CGP 35348, or vehicle to determine the effects of both antagonists on postnatal neurogenesis. Due to GABA(B) receptor blockade by CGP 35348, immunohistochemistry revealed a decrease in the number of NeuroD1 positive intermediate progenitor cells and a reduction of proliferative Nestin-positive neuronal stem cells at the DG. The impairment of hippocampal neurogenesis at this stage of differentiation is in line with a significantly decreased RNA expression of the transcription factors Pax6, Ascl1, and NeuroD1. Interestingly, the number of NeuN-positive postmitotic neurons was not affected by GABA(B) receptor blockade, although strictly associated transcription factors for postmitotic neurons, Tbr1, Prox1, and NeuroD2, displayed reduced expression levels, suggesting impairment by GABA(B) receptor antagonization at this stage of neurogenesis. Antagonization of GABA(B) receptors decreased the expression of neurotrophins (BDNF, NT-3, and NGF). In contrast to the GABA(B) receptor blockade, the GABA(A) receptor antagonization revealed no significant changes in cell counts, but an increased transcriptional expression of Tbr1 and Tbr2. We conclude that GABAergic signaling via the metabotropic GABA(B) receptor is crucial for hippocampal neurogenesis at the time of rapid brain growth and of the postnatal GABA shift. Differentiation and proliferation of intermediate progenitor cells are dependent on GABA. These insights become more pertinent in preterm infants whose developing brains are prematurely exposed to spostnatal stress and predisposed to poor neurodevelopmental disorders, possibly as sequelae of early disruption in GABAergic signaling.

description: On the basis of first-principles GW calculations, we study the quasiparticle properties of the guanine, adenine, cytosine, thymine, and uracil DNA and RNA nucleobases. Beyond standard G0W0 calculations, starting from Kohn-Sham eigenstates obtained with (semi)local functionals, a simple self-consistency on the eigenvalues allows to obtain vertical ionization energies and electron affinities within an average 0.11 eV and 0.18 eV error respectively as compared to state-of-the-art coupled-cluster and multi-configurational perturbative quantum chemistry approaches. Further, GW calculations predict the correct π-character of the highest occupied state, thanks to several level crossings between density functional and GW calculations. Our study is based on a recent gaussian-basis implementation of GW with explicit treatment of dynamical screening through contour deformation techniques.

description: Many researchers have analyzed the equilibrium adsorption isotherm mechanism of water vapor molecules on 4A, 3A, Y and X zeolites for decades. The demand for moisture removal continues to increase along with the increasing stringency of requirements for product quality control and production energy efficiency. Due to the negative charge of the zeolite framework, exchangeable compensation cations such as Na+, Li+, K+, Ba2+, Mg2+, and Ca2+ might be added. These cations are located at different sites within the framework and with different concentrations. Each cation shows a strong affinity to bond with water molecules. Adsorption sites must show a characteristic energy signature corresponding to the adsorbed amount. The values of enthalpies and entropies at each site are different since the bonding strength between the moisture molecules and cations of the site is also different adsorptive properties and selectivity. This investigation of the water vapor adsorption mechanism reveals that size, location, and type of exchangeable compensation cations have a concrete relationship to the adsorption process and zeolite cage capacity.
Splitting space : destabilizing the suburban house in postwar art and contemporary horror film
Creators: name: Prasad, Marcus
Publisher: name: University of British Columbia
Year: 2021

description: This thesis explores the representation of the suburban house and the concept of suburbia as an extension of social normativity in America following World War II and into the contemporary period. I pursue this line of investigation by analyzing three works that question and disrupt this distinct space – Dan Graham’s Homes for America (1966-67), Gordon Matta-Clark’s Splitting (1974), and James Wan’s Insidious (2010). While seemingly disparate in terms of media and chronology, the following reveals the unique means through which each work exposes a shared disdain toward suburban development and its deep ties to normativity. By closely examining how each artist represents the space of the home and its subsequent undoing, a network of cultural production that seeks to destabilize the fraught idealism that has long been attributed to the suburbs is formed. Drawing from spatial and temporal theory, I articulate how normativity is formed in the space of the suburbs through structured rhythms, movements, and gestures that become attributed to the heterosexual, white, middle- to upper-class family. My investigations of postwar art then create a methodology used in my following analysis of contemporary horror film. This methodology adopts from queer theory a process of estrangement, a deviation from the normative space of the suburbs that seeks to disrupt and challenge existing scripts within dominant social frameworks. As such, this thesis provides a new method through which postwar art and contemporary film may be analyzed, away from canonical or genre prescriptions, in addition to a justification for continued representational engagements with the suburban house in the contemporary period.

description: Brevicaudosaurus jiyangshanensis, gen. et sp. nov., a new nothosauroid, is established on the basis of two nearly complete skeletons from the Middle Triassic (Ladinian) of China. Its skull is diagnostic in having a wide and constricted snout, a large supratemporal fossa slightly larger than the orbit, and a parietal table strongly constricted posteriorly. Postcranial specializations include a short trunk with 14 dorsal vertebrae, a short tail shorter than the skull-neck region in length, a stout anterolateral process on the clavicle, an extremely massive and broadened mid-diaphysis of the humerus, a strongly expanded proximal head of the ulna, seven ossified carpals, and a phalangeal reduction in the pes. In addition, the strongly pachyostotic postcranial skeleton may indicate a slow mode of swimming underwater and a benthic carnivorous feeding habit for B. jiyangshanensis. Phylogenetically, it is the sister taxon of the Nothosaurus-Lariosaurus clade within Nothosauroidea. The discovery of this new nothosauroid not only contributes to local faunal diversity and expands the known range of sauropterygian life styles during the late Middle Triassic, but also provides a chance to test the phylogenetic relationships of the Eosauropterygia hypothesized by previous studies. http://zoobank.org/urn:lsid:zoobank.org:pub:026D8680-CC71-47BD-A681-F5B6F140B84

description: Three fermions with strongly repulsive interactions in a spherical harmonic trap, constitute the simplest nontrivial system that can exhibit the onset of itinerant ferromagnetism. Here, we present exact solutions for three trapped, attractively interacting fermions near a Feshbach resonance. We analyze energy levels on the upper branch of the resonance where the atomic interaction is effectively repulsive. When the s-wave scattering length a is sufficiently positive, three fully polarized fermions are energetically stable against a single spin-flip, indicating the possibility of itinerant ferromagnetism, as inferred in the recent experiment. We also investigate the high-temperature thermodynamics of a strongly repulsive or attractive Fermi gas using a quantum virial expansion. The second and third virial coefficients are calculated. The resulting equations of state can be tested in future quantitative experimental measurements at high temperatures and can provide a useful benchmark for quantum Monte Carlo simulations.

A Holder Continuous Nowhere Improvable Function with Derivative Singular Distribution

Subjects: subject: Classical Analysis and ODEs (math.CA)

description: We present a class of functions $\mathcal{K}$ in $C^0(\R)$ which is variant of the Knopp class of nowhere differentiable functions. We derive estimates which establish $\mathcal{K} \sub C^{0,\al}(\R)$ for $0\al$. In particular, all $K$'s are nowhere differentiable with derivatives singular distributions. $\mathcal{K}$ furnishes explicit realizations of the functional analytic result of Berezhnoi. Recently, the author and simulteously others laid the foundations of Vector-Valued Calculus of Variations in $L^\infty$ (Katzourakis), of $L^\infty$-Extremal Quasiconformal maps (Capogna and Raich, Katzourakis) and of Optimal Lipschitz Extensions of maps (Sheffield and Smart). The "Euler-Lagrange PDE" of Calculus of Variations in $L^\infty$ is the nonlinear nondivergence form Aronsson PDE with as special case the $\infty$-Laplacian. Using $\mathcal{K}$, we construct singular solutions for these PDEs. In the scalar case, we partially answered the open $C^1$ regularity problem of Viscosity Solutions to Aronsson's PDE (Katzourakis). In the vector case, the solutions can not be rigorously interpreted by existing PDE theories and justify our new theory of Contact solutions for fully nonlinear systems (Katzourakis). Validity of arguments of our new theory and failure of classical approaches both rely on the properties of $\mathcal{K}$.

description: The aim of this work was to design the main circuit of the electric compounds of a nuclear power plant with RBMKÂ·1000 reactors with a capacity of 6Â·500 MW and the choice of the parameters of its electrical equipment. According to the results of technical and economic calculation of two electrical circuits, the final circuit was chosen. According to the initial data, the selection of circuit elements such as generators, transformers and autotransformer was made. Using the reference data of the selected electrical equipment, a replacement circuit was constructed, and short-circuit currents were calculated at various points. Based on the values obtained, conductive parts and switching equipment such as switches and disconnectors are selected. Then, current and voltage measuring transformers were selected.

description: An initial investigation of two poorly studied eclipsing binaries separated by ~3' in the sky is presented. The first star (GSC 2576-01248) was discovered by the TrES exoplanet search project. The second one (GSC 2576-02071) was identified by the authors during CCD observations of GSC 2576-01248. We combine our dedicated CCD photometry with the archival TrES observations and data from the digitized photographic plates of the Moscow collection to determine periods of the two variable stars with high precision. For GSC 2576-01248, addition of historical photographic data provides a major improvement in accuracy of period determination. No evidence for period change in these binary systems was found. The lightcurve of GSC 2576-01248 is characterized by a prominent variable O'Connell effect suggesting the presence of a dark starspot and asynchronous rotation of a binary component. GSC 2576-02071 shows a shift of the secondary minimum from the phase =0.5 indicating a significant orbit eccentricity.

description: We present a catalog of 2,990 extended sources in a 1deg x1deg area centered on M33 using the MegaCam camera on the 3.6m Canada-France-Hawaii telescope (CFHT). The catalog includes 599 new candidate stellar clusters, 204 previously confirmed clusters, 1,969 likely background galaxies and 218 unknown extended objects. We present ugriz integrated magnitudes of the candidates and confirmed star clusters as well as full width at half maximum, ellipticity and stellarity. Based on the properties of the confirmed star clusters, we select a sub-sample of highly probable clusters composed of 246 objects. The integrated photometry of the complete cluster catalog reveals a wide range of colors from -0.4 < (g-r) < 1.5 and -1.0 < (r-i) < 1.0 with no obvious cluster subpopulations. Comparisons with models of simple stellar populations suggest a large range of ages some as old as ~ 10 Gyrs. In addition, we find a sequence in the color-color diagrams that deviates from the expected direction of evolution. This feature could be associated with very young clusters (< 10^7 yrs) possessing significant nebular emission. Analysis of the radial density distribution suggests that the cluster system of M33 has suffered from significant depletion possibly due to interactions with M31. We also detect a gap in the cluster distribution in the color-color diagram at (g-r) ~ 0.3 and (u-g) ~ 0.8. This gap could be interpreted as an evolutionary effect. This complete catalog provides promising targets for deep photometry and high resolution spectroscopy to study the structure and star formation history of M33.

Odyssey Towards a Sirenic Thinking: An Attempt at a Self-Criticism of the Listening Paradigm Within Sound Studies

description: This text departs from a contradictory claim in deaf studies and sound studies: both disciplines describe a hierarchical regime of the sensible – visuocentrism and audiocentrism – which they try to counter with conceptualisations as “acoustemology” or “deaf gain.” However, as we argue, they both thereby erect what they claim to overcome: a sensual regime that privileges one sense over another and a restricted conception of subjectivity deriving from it. First, we draw a philosophical line in the critique of sensual regimes. Then we propose a figure for the transcendence of the separation of the sensible: in re-reading of the myth of Odysseus and the sirens, we engage various examples from literature, art, and acoustics to describe sirens as a mythological and technical archetype of the transcendence of the sensual regime, as well as reified subjectivity. The question, then, is not how to escape the sirens, but how they can be approached. It is necessary, we argue, for sound studies to develop a critical self-consciousness of its own restricted concepts in order to move from sonic thinking towards a sirenic thinking.

description: The Gravity Advanced Package is an instrument composed of an electrostatic accelerometer called MicroSTAR and a rotating platform called Bias Rejection System. It aims at measuring with no bias the non-gravitational acceleration of a spacecraft. It is envisioned to be embarked on an interplanetary spacecraft as a tool to test the laws of gravitation. MicroSTAR is based on Onera's experience and inherits in orbit technology. The addition of the rotating platform is a technological upgrade which allows using an electrostatic accelerometer to make measurements at low frequencies with no bias. To do so, the Bias Rejection System rotates MicroSTAR such that the signal of interest is separated from the bias of the instrument in the frequency domain. Making these unbiased low-frequency measurements requires post-processing the data. The signal processing technique developed for this purpose is the focus of this article. It allows giving the conditions under which the bias is completely removed from the signal of interest. And the precision of the unbiased measurements can be fully characterized: given the characteristics of the subsystems, it is possible to reach a precision of 1 pm s$^{-2}$ on the non-gravitational acceleration for an integration time of 3 h.

description: Evaporative coolers utilize the evaporation of water to cool air. The advantage is to use only a fraction of the energy of typical compressor-based cooling systems. The objective of the current investigation is to introduce an effective small system dealing only with primary flow in which the indirect and direct processes exist in the same channel. This innovative system provides an appropriate alternative to mechanical vapor compression systems for dry climate regions. The importance of such a system is not limited to energy saving and environmental safety but can also effectively handle the bacteria source, maintenance, and cleaning. Moreover, eliminating the dependency on a secondary flow will either increase the air supply flow rate by increasing primary air flow channels or reducing the evaporation size. An analytical model is developed for the coupled heat and mass transfer processes in a hybrid (indirect and direct) evaporative cooler. The model considers the flow and channel wall temperature, which fluctuates in the indirect (dry) section and in the direct (wet) section. Diffusion mass transfer of water vapor and relative humidity variation within the channel are considered and combined with convection heat transfer equations to predict the flow effect. However, the effects of changing the operation conditions and channel wall thickness were taken into account during the prediction of the system's performance. Comparative results show that the hybrid concept has a great potential in the future of evaporative cooler system.

description: Progress in oncological treatment has led to an improved long-term survival of young male cancer patients over the last decades. However, standard cancer treatments frequently implicate fertility-damaging potential. Cryopreservation of sperm is the current standard option to preserve patient's fertility after treatment, yet long-term data on usage and reproductive experiences is still limited. Natural fertility after treatment and especially in relation to the type of treatment has been poorly analyzed so far. Therefore, we performed a retrospective survey including male patients with an indication for gonadotoxic treatment who cryopreserved reproductive material at our institution between 1994 and 2017. Study questionnaires regarding treatment, material usage, and reproductive outcomes were sent to eligible patients. Additionally, semen analyses of study participants from the time of cryopreservation were evaluated. A total of 99 patients were included in the study. Respondents' median age was 38.0 years. Most frequent diagnoses were testicular cancer (29.3%) and lymphoma (26.3%). A further 8.1% suffered from autoimmune diseases. Testicular cancer patients had a significantly lower pre-treatment median sperm concentration (18.0 million/ml) compared to non-testicular cancer patients (54.2 million/ml). Until November 2020, the determined sperm usage and cumulative live-birth rate per couple were 17.2% and 58.8%, respectively. Most sperm users received treatments with high (40.0%) or intermediate (33.3%) gonadotoxic potential. 20.7% of all patients reported to had fathered at least one naturally conceived child after treatment, this being the case especially if they had been treated with less or potentially gonadotoxic therapies. In conclusion, our findings emphasize the importance of sperm cryopreservation in the context of male fertility preservation. Furthermore, they indicate that the gonadotoxic potential of patients' treatments could represent a predictive factor for sperm usage.
The Amplitude Equation for the Rosensweig Instability in Magnetic Fluids and Gels

description: The Rosensweig instability has a special character among the frequently discussed instabilities. One distinct property is the necessary presence of a deformable surface, and another very important fact is, that the driving force acts purely via the surface and shows no bulk effect. These properties make it rather difficult to give a correct weakly nonlinear analysis. In this paper we give a detailed derivation of the appropriate amplitude equation based on the hydrodynamic equations emphasizing the conceptually new procedures necessary to deal with the distinct properties mentioned above. First the deformable surface requires a fully dynamic treatment of the instability and the observed stationary case can be interpreted as the limiting case of a frozen-in characteristic mode. Second, the fact that the driving force is manifest in the boundary conditions, only, requires a considerable change in the formalism of weakly nonlinear bifurcation theory. To obtain the amplitude equations a combination of solubility conditions and (normal stress) boundary conditions has to be invoked in all orders of the expansions.
