Hyalomma isaaci

description: Hyalomma isaaci Sharif, 1928
 In India, Hy. isaaci is found in a variety of climate zones. The species was recorded in Vietnam as Hy. marginatum indosinense (Kolonin 1995). Toumanoff (1944) was the first to find this Hyalomma in Southeast Asia, where he reported 4 males on a banteng (Bos sondaicus) in Vietnam (identified as Hy. dromedarii indosinensis). The next collection was made in 1992 by Kolonin (2 males and 1 female) from the same host and also in Vietnam. A male/ female pair of specimens was reported on clothing in Myanmar (Robbins et al. 2002).
Descriptions of all active life history stages, together with illustrations of the male and female and line drawings of the nymphal and larval capitula, scuta and coxae, are available in Geevarghese & Dhanda (1987).

description: Οι αναστολείς των φωσφοδιεστερασών έχουν καταλάβει ένα μεγάλο μέρος της φαρμακευτικής αγοράς λόγω του ασφαλούς τους προφίλ και των πολλαπλών χρήσεων που φαίνεται ότι θα αυξηθούν στο εγγύς μέλλον. Η επίδραση αυτών των φαρμάκων σε συστήματα που ενέχονται στην καθημερινή ζωή, ως επιθυμητές ή ανεπιθύμητες δράσεις είναι πολλαπλές και για το λόγο αυτό χρήζουν περαιτέρω διερεύνησης. Στην παρούσα μελέτης μελετήθηκε η επίδραση της σιλδεναφίλης, ενός αναστολέα των φωσφοδιεστερασών τύπου 5, στις μεταβολικές παραμέτρους (πρόσληψη τροφής, ύδατος, αποβολή ούρων και κοπράνων) καθώς και στη συμπεριφορά επίμυων που υποβάλλονταν σε στέρηση τροφής. Διαπιστώθηκε ότι τα πειραματόζωα στα οποία χορηγήθηκε 1mg/kg σιλδεναφίλης ενδοπεριτοναϊκώς κατανάλωσαν στατιστικώς σημαντικά περισσότερη τροφή, μεγαλύτερη ποσότητα ύδατος, παρήγαγαν μικρότερη ποσότητα ούρων και μεγαλύτερη ποσότητα κοπράνων. Από τη δοκιμασία του υπερυψωμένου σταυροειδούς λαβυρίνθου διαπιστώνεται ότι τα ζώα που λαμβάνουν σιλδεναφίλη και είτε σιτίζονται είτε στερούνται τροφής, εμφανίζουν μεγαλύτερο αριθμό εισόδων στα ανοικτά και κλειστά πεδία, από τα αντίστοιχα πειραματόζωα των ομάδων ελέγχου. Κατά τη δοκιμασία της οσφρητικής κοι¬νωνικής μνήμης τα πειραματόζωα που έλαβαν σιλδεναφίλη και διατρέφονταν κανονικά παρουσίασαν στατιστικώς σημαντικά μικρότερο χρόνο πρώτης και δεύτερης επαφής με το νεαρό ζώο. Οι λόγοι των χρόνων της πρώτης προς τη δεύτερη επαφή είναι στατιστικώς όμοιοι για όλες τις κατηγορίες πειραματοζώων. Συμπερασματικά, η σιλδεναφίλη φαίνεται ότι παρόλο που επάγει τις γνωσιακές διαδικασίες, όπως η μνήμη και μάθηση σε μακρόχρονη θεραπεία, σε άμεση χορήγηση μειώνει τη βραχεία μνήμη ενώ εμφανίζει σημαντική αντιαγχώδη δράση στο πειραματόζωο.
description: Several PDE inhibitors have been developed and used as therapeutic agents because of their safety profile and their multiple pharmacological applications. The effects of these drugs on patients’ regular life, either beneficial or adverse effects, are many and therefore further clinical studies are required. We studied the effect of the selective phosphodiesterase type 5 inhibitor, sildenafil on metabolic parameters (food and water intake, excretion of urine and stool) and on the behavior of food-deprived rats. We found that animals treated with sildenafil (1mg/kg i.p.) consumed more food and water and produced less urine and more stools. In the plus maze test animals treated with the inhibitor, food deprived or not, present more entries in the open and in the closed arms of the maze. In the olfactory memory test, rats treated with sildenafil and fed normally had shorter first and second contact with the young animal. We conclude that sildenafil, although induces memory and learning processes in long-term therapy, in short-term administration impairs short-term memory and has an anti-stress effect on the animal.
Astrochemistry of the Dust Around Supermassive Black Holes in the New Era of Transient Infrared Sky Surveys

Year: 2021

description: We have initiated the first spectroscopic dust reverberation program on active galactic nuclei in the near-infrared. Spectroscopy enables measurement of dust properties auch as flux, temperature and covering factor with much higher precision than photometry. But its particular strength is that it can measure both luminosity-based dust radii and dust response times. As I will show, this can constrain the chemistry of the dust. In this talk, I will present recently published results from a 1-yr campaign on NGC 5548 and discuss preliminary results from completed or on-going campaigns on Mrk 876, Mrk 509 and 3C 273. Our intent now is to take the spectroscopic dust reverberation program to a larger scale. I will discuss the different ways in which this can be successfully accomplished in the new era of transient infrared sky surveys both from the ground and from space. In particular, exploiting the time-domain capabilities of the deep surveys of upcoming space missions such as Euclid, Roman Space Telescope and SPHEREx will be a once-in-a-lifetime opportunity for our ambitious project.

description: Aim. Intraoperative hypoxemia is often due to atelectasis, which can be improved by recruitment maneuvers. Aim of the study: a) to investigate intraoperative hypoxemia in surgical patients and its correlation to specific demographic data, b) to investigate the effectiveness of recruitment maneuvers in improving oxygenation. Materials and methods. 430 patients undergoing elective general surgery were studied. Demographic data recorded: age, sex, ASA-PS classification, BW, BMI, AH, CAD, DM, type and duration of surgery. Their predictive value for hypoxemia was evaluated. Hypoxemia was defined as PaO2/FiO2<300. Patients with hypoxemia were allocated to 4 study groups: Group A: 3 hyperinflations at 40cmH2O and PEEP 10cmH2O, Group B: PEEP 10cmH2O, Group C: 3 hyperinflations and PEEP 5cmH2O, Group D: no intervention. The impact of these interventions on oxygenation was evaluated. Statistical analysis: ROC and χ2 for the predictive value of demographic data, repeated measures ANOVA for the comparison between groups.Results-Conclusions. 150/430 (34,8%) patients developed hypoxemia. Positive predictive value was observed for: age, BMI, duration of surgery and AH. The administration of 3 hyperinflations and PEEP 10cmH2O is more efficient than the other maneuvers in improving intraoperative oxygenation.

description: The electronic structure of $p$-type doped \BiTe is studied by angle resolved photoemission spectroscopy (ARPES) to experimentally confirm the mechanism responsible for the high thermoelectric figure of merit. Our ARPES study shows that the band edges are located off the $Γ$-Z line in the Brillouin zone, which provides direct observation that the spin-orbit interaction is a key factor to understand the electronic structure and the corresponding thermoelectric properties of \BiTe. Successive time dependent ARPES measurement also reveals that the electron-like bands crossing E$_F$ near the $\underlineΓ$ point are formed in an hour after cleaving the crystals. We interpret these as surface states induced by surface band bending, possibly due to quintuple inter-layer distance change of \BiTe.

description: Rigorous justification of the Hubbard-Stratonovich transformation for the Pruisken-Schäfer type of parameterisations of real hyperbolic O(m,n)-invariant domains remains a challenging problem. We show that a naive choice of the volume element invalidates the transformation, and put forward a conjecture about the correct form which ensures the desired structure. The conjecture is supported by complete analytic solution of the problem for groups O(1,1) and O(2,1), and by a method combining analytical calculations with a simple numerical evaluation of a two-dimensional integral in the case of the group O(2,2).

Selective withdrawal of a linearly stratified fluid in a triangular reservoir
Creators: name: Hnidei, Stephen D.
Publisher: name: University of British Columbia
Year: 2010

description: The water in most reservoirs is density stratified with depth. This stratification leads to the inhibition of vertical movement, consequently, when water is withdrawn from the reservoir it tends to move in a jet-like layer called a withdrawal layer, towards the sink. By placing the sink at a certain depth, one is able to selectively withdrawal water from a limited range of depths and thus obtain water of a desired quality. Much work has been done in this field by considering a simplified boundary geometry, usually rectangular. However little attention has been given to the effects of accurate boundary geometry. For this thesis, five numerical experiments were conducted for the problem of a two-dimensional, viscous, incompressible, slightly-stratified flow towards a sink in a triangular reservoir.

description: We investigate the geometrical structure of multipartite states based on the construction of toric varieties. We show that the toric variety represents the space of general pure states and projective toric variety defines the space of separable set of multi-qubits states. We also discuss in details the construction of single-, two-, three-, and multi- qubits states. This construction gives a very simple and elegant visual representation of the geometrical structure of multipartite quantum systems.

description: Abstract: - The emergence of multidrug-resistant (MDR) bacteria has significantly compromised the effectiveness of conventional antibiotics, necessitating the exploration of alternative therapeutic strategies. Bacteriophages, or phages, have garnered renewed interest as potential agents against MDR infections, particularly those caused by ESKAPE pathogens, which include Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species. This review discusses the unique mechanisms by which bacteriophages target and kill these pathogens, highlighting their potential advantages over traditional antibiotics. The article also explores recent advancements in phage therapy, including isolation techniques, in vitro and in vivo efficacy studies, and innovative engineering approaches to enhance phage activity. Despite the promise of phage therapy, challenges such as host immune responses, regulatory hurdles, and production standardization remain. Future research directions are outlined to improve phage therapy's efficacy and integration with existing antimicrobial strategies. Overall, bacteriophage therapy represents a promising avenue for mitigating antimicrobial resistance and improving clinical outcomes in the treatment of infections caused by ESKAPE pathogens.

Ixodes acutitarsus

description: Ixodes acutitarsus (Karsch, 1880)
 Ixodes acutitarsus is a widely distributed Oriental and Palearctic species that has been reported from East, Southeast and South Asia, including Japan, China, India, Tibet and Nepal. In Southeast Asia it is known from Myanmar, Thailand and Vietnam (Petney and Keirans 1994; Kolonin 2009). It occurs in a variety of habitats and has a high altitudinal range (300-3,500 m above sea level) (Schulze 1939; Clifford et al. 1975; Tanskul et al. 1983; Keirans 1985). Filippova (1977) considers this tick to be a representative of the Indo-Malayan faunistic region.
 Ixodes acutitarsus is the largest of the Southeast Asian Ixodes species; indeed, it is the largest known Ixodes in the world. Adults have been collected from medium-sized to large wild and domestic mammals in forested areas, while immatures parasitize smaller mammals (Clifford et al. 1975). There is also a record from birds (Guglielmone et al. 2014). Humans are relatively frequently attacked (Schulze 1939; Clifford et al. 1975; Tanskul et al. 1983; Heath and Hardwick 2011; Chao and Shih 2012).
 Kitaoka et al. (1975) provide information on laboratory rearing. The female is described and illustrated in Yamaguti et al. (1971), nymphs and larvae in Clifford et al. (1975).

description: We construct N=1 supersymmetry in 4+2 dimensions compatible with the theoretical framework of 2T physics field theory and its gauge symmetries. The fields are arranged into 4+2 dimensional chiral and vector supermultiplets, and their interactions are uniquely fixed by SUSY and 2T-physics gauge symmetries. Many 3+1 spacetimes emerge from 4+2 by gauge fixing. Gauge degrees of freedom are eliminated as one comes down from 4+2 to 3+1 dimensions without any remnants of Kaluza-Klein modes. In a special gauge, the remaining physical degrees of freedom, and their interactions, coincide with ordinary N=1 supersymmetric field theory in 3+1 dimensions. In this gauge, SUSY in 4+2 is interpreted as superconformal symmetry SU(2,2|1) in 3+1 dimensions. Furthermore, the underlying 4+2 structure imposes some interesting restrictions on the emergent 3+1 SUSY field theory, which could be considered as part of the predictions of 2T-physics. One of these is the absence of the troublesome renormalizable CP violating F*F terms. This is good for curing the strong CP violation problem of QCD. An additional feature is that the superpotential is required to have no dimensionful parameters. To induce phase transitions, such as SUSY or electro-weak symmetry breaking, a coupling to the dilaton is needed. This suggests a common origin of phase transitions that is driven by the vacuum value of the dilaton, and need to be understood in a cosmological scenario as part of a unified theory that includes the coupling of supergravity to matter. Another interesting aspect is the possibility to utilize the inherent 2T gauge symmetry to explore dual versions of the N=1 theory in 3+1 dimensions. This is expected to reveal non-perturbative aspects of ordinary 1T field theory.

Zum Rollenverständnis von Lehrpersonen im DaZ-Unterricht mit Erwachsenen
Creators: name: Schallaböck, Maria
Year: 2020

description: DaZ-Kurse finden in einem Umfeld statt, das von migrationsgesellschaftlichen Machtverhältnissen und Differenzordnungen wie Othering, (kulturellem) Rassismus, erschwertem Zugang zum Arbeitsmarkt oder Deutschlernverplichtung für Neuzugewanderte und der Forderung nach Integration durchwoben ist. In vorliegender Arbeit wird der Frage nachgegangen, welche dieser gesellschaftlichen Dynamiken und Diskurse inwiefern einen Einfluss auf die Wahrnehmung der DaZ-Lehrkräfte von ihrer Rolle und von professionellem Handeln haben und was machtkritische Anforderungen an Professionalität im migrationsgesellschaftlichen Kontext darstellen könnten, wofür im theoretischen Teil einige pädagogische Ansätze diskutiert werden, wobei insbesondere der differenzsensiblen und machtkritischen Perspektive der Migrationspädagogik nachgegangen wird. Um Erkenntnisse über Rollenverständnis der Lehrenden, Einflüsse darauf, Zusammenhänge und ihr Verständnis von Professionalität in den genannten Verhältnissen zu gewinnen, wurden DaZ-Lehrpersonen unterschiedlicher Institute in qualitativen teilstandardisierten Interviews befragt. Die Befragten verstehen ihre Rolle dabei hauptsächlich als Sprachvermittler und stellen diese Funktion in den Vordergrund ihrer Überlegungen zur Kursgestaltung, sie positionieren sich gegen unterschiedliche Ausformungen und Auswirkungen von Rassismus im Kurs, welche sie wahrnehmen, wobei der Integrationsdiskurs teils das Rollenverständnis mitbeeinflusst, größtenteils tritt jedoch eine autonomiefördernde Haltung zu Tage. Als weitere einflussreiche Faktoren auf das Rollenverständnis zeigen sich berufliche Erfahrungen, das Kursbuch, die institutionellen Rahmenbedingungen, Einstellungen, die Wünsche und Bedürfnisse der Teilnehmenden, die Institution Schule sowie mediale Diskurse.

description: We describe and study a certain class of modified gravity theories. Our starting point is Plebanski formulation of gravity in terms of a triple B^i of 2-forms, a connection A^i and a ``Lagrange multiplier'' field Psi^ij. The generalization we consider stems from presence in the action of an extra term proportional to a scalar function of Psi^ij. As in the usual Plebanski general relativity (GR) case, a certain metric can be constructed from B^i. However, unlike in GR, the connection A^i no longer coincides with the self-dual part of the metric-compatible spin-connection. Field equations of the theory are shown to be relations between derivatives of the metric and components of field Psi, as well as its derivatives, the later being in contrast to the GR case. The equations are of second order in derivatives. An analog of the Bianchi identity is still present in the theory, as well as its contracted version tantamount to energy conservation equation.

A 5-Dimensional Spherical Symmetric Solution in Einstein-Yang-Mills Theory With Gauss-Bonnet Term

description: We present a numerical solution on a 5-dimensional spherically symmetric space time, in Einstein-Yang-Mills-Gauss-Bonnet theory using a two point boundary value routine. It turns out that the Gauss-Bonnet contribution has a profound influence on the behaviour of the particle-like solution: it increases the number of nodes of the YM field. When a negative cosmological constant in incorporated in the model, it turns out that there is no horizon and no singular behaviour of the model. For positive cosmological constant the model has singular behaviour.

Behavior of X-Ray Dust Scattering and Implications for X-Ray Afterglows of Gamma-Ray Bursts

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: The afterglows of gamma-ray bursts (GRBs) have commonly been assumed to be due to shocks sweeping up the circum-stellar medium. However, most GRBs have been found in dense star-forming regions where a significant fraction of the prompt X-ray emission can be scattered by dust grains. Here we revisit the behavior of dust scattering of X-rays in GRBs. We find that the features of some X-ray afterglows from minutes to days after the gamma-ray triggers are consistent with the scattering of prompt X-ray emission from GRBs off host dust grains. This implies that some of the observed X-ray afterglows (especially those without sharp rising and decaying flares) could be understood with a dust-scattering--driven emission model.

description: Die Inanspruchnahme von Supervsision/Coaching dient in vielen Berufsfeldern als Möglichkeit der Professionalierung, z.B. auch in der Lehrer*innenausbildung. In der vorliegen Studie wird die Intention von Junglehrer*innen unstersucht, in ihrem Berufsleben Supervision/Coaching in Anspruch zu nehmen. Basierend auf der Theorie des geplanten Verhaltens (Theory of planned Bevaviour) wurde ein reliaber und valider Fragebogen zu dieser Thematik entwickelt, der von 132 Leher*innen berbeitet wurde. Es zeigte sich, dass die Intention Supervison/Coaching in Anspruch zu nehmen in erster Linie von den Einstellungen und der (beruflichen) sozialen Norm der Proband*innen abhing. Die empfundene soziale Norm der Stichprobe war gering ausgeprägt, hingegen waren die Einstellungen zur Supervision/zum Coachimg der Stichprobe positiv. Trotzdem war die Bereitschaft, an einer Supervison/einem Coaching teilzunehmen nur im durchschnittlichen Bereich verortet. Die statistischen Befunde der vorliegenden Untersuchung werden vor dem Hintergrund einer hermeneutisch-rekonstruktiven Perspektive diskutiert, insbesondere die beobachtete „Attitude-Intention-Gap“. Zudem wird das Verhältnis Supervison/Coaching und Schule perspektivisch beleuchtet.

description: Bosons with non-zero spin exhibit a rich variety of superfluid and insulating phases. Most phases support coherent spin oscillations, which have been the focus of numerous recent experiments. These spin oscillations are Rabi oscillations between discrete levels deep in the insulator, while deep in the superfluid they can be oscillations in the orientation of a spinful condensate. We describe the evolution of spin oscillations across the superfluid-insulator quantum phase transition. For transitions with an order parameter carrying spin, the damping of such oscillations is determined by the scaling dimension of the composite spin operator. For transitions with a spinless order parameter and gapped spin excitations, we demonstrate that the damping is determined by an associated quantum impurity problem of a localized spin excitation interacting with the bulk critical modes. We present a renormalization group analysis of the quantum impurity problem, and discuss the relationship of our results to experiments on ultracold atoms in optical lattices.

description: We propose a hybrid quantum circuit with both charge and flux qubits connected to a large Josephson junction that gives rise to an effective inter-qubit coupling controlled by the external magnetic flux. This switchable inter-qubit coupling can be used to transfer back and forth an arbitrary superposition state between the charge qubit and the flux qubit working at the optimal point. The proposed hybrid circuit provides a promising quantum memory because the flux qubit at the optimal point can store the tranferred quantum state for a relatively long time.

description: Let U be a real form of a complex semisimple Lie group, and tau, sigma, a pair of commuting involutions on U. This data corresponds to a reflective submanifold of a symmetric space, U/K. We define an associated integrable system, and describe how to produce solutions from curved flats. The solutions are shown to correspond to various special submanifolds, depending on which homogeneous space U/L one projects to. We apply the construction to a question which generalizes, to the context of reflective submanifolds of arbitrary symmetric spaces, the problem of isometric immersions of space forms with negative extrinsic curvature and flat normal bundle. For this problem, we prove that the only cases where local solutions exist are the previously known cases of space forms, in addition to constant curvature Lagrangian immersions into complex projective and complex hyperbolic spaces. We also prove non-existence of global solutions in the compact case. The solutions associated to other reflective submanifolds correspond to special deformations of lower dimensional submanifolds. As an example, we obtain a special class of surfaces in the 6-sphere.

description: Der Beitrag beschreibt die Ergebnisse einer Fragebogenstudie aus dem Projekt Vielfalt stärken – Sprachförderung für Kinder mit Deutsch als Zweitsprache der Universität Paderborn. Das Projekt zielt darauf ab, Lehramtsstudierenden aller Studiengänge und Fächer komplexe Lerngelegenheiten außerhalb der obligatorischen Praktika in der ersten Phase der Lehrer*innenbildung zu eröffnen. Die Studierenden werden in einem universitären Begleitseminar zu Sprachförderlehrkräften ausgebildet und unterrichten in Kleingruppen Schüler*innen mit Migrationshintergrund und Sprachförderbedarf an Schulen in Stadt und Kreis Paderborn. Mit einer sprachspezifischen Ausrichtung und einer intensiven Betreuung findet die schulpraktische Lerngelegenheit semesterbegleitend statt. Den Studierenden wird damit über das Modul „Deutsch für Schülerinnen und Schüler mit Zuwanderungsgeschichte“ (DSSZ) hinaus eine fakultative, praxisnahe Vertiefung im Bereich Deutsch als Zweitsprache, Interkulturalität und Mehrsprachigkeit angeboten. Der Beitrag geht nach Darstellung des Projektkonzeptes auf die empirische Auswertung eines zur Projektevaluation und Selbsteinschätzung genutzten Fragebogens (n=53) ein. Die empirischen Befunde verdeutlichen, dass die selbstständige wöchentliche Unterrichtsplanung und -durchführung nach subjektiver Einschätzung der Studierenden den größten Effekt auf allgemeine wie sprachdidaktische Fähigkeiten und die Entwicklung der Lehrpersönlichkeit nimmt. Die Projektarbeit als Lerngelegenheit der Sprachförderung im Lehramtsstudium könnte demnach insbesondere für praktische DaZ-Kompetenzen und Lehrkompetenzen entwicklungsförderlich sein. Für die Ausbildung der Sprachförderlehrkräfte und ihre positiven Erfahrungen ist zentral, dass eine enge Betreuung und eine sorgfältige Begleitung der Studierenden gegeben sind.
