description: Das CRM-Verfahren bildet durch seine kontinuierliche Bewertungsmöglichkeit eine sehr gute Ergänzung zu den gängigen Methoden im Repertoire der Wirkungsforschung. Um diesen Mehrwert voll ausschöpfen zu können, wird als Verfahrensoptimierung die Entwicklung einer Open-Source-Softwarelösung begleitet. Dabei werden in dieser Arbeit theoretische Überlegungen zu den relevanten Einflussfaktoren von Gesprächsbewertungen ebenso einbezogen, wie die Sprechstimme als rhetorischer Wirkungsfaktor und die Kapazitäten der Hörenden bei der Wirkungsbewertung mittels eines kontinuierlichen Messinstruments. Die Überprüfung des optimierten CRM-Verfahrens erfolgt mittels eines Anwendungsfalls aus der sprechwissenschaftlichen Telekommunikationsforschung im Rahmen eines User-Acceptance-Tests. Dabei wird die Funktionalität und Bedienerfreundlichkeit der entwickelten CRM-Softwarelösung unter Beachtung der für die Sprechwissenschaft relevanten Kriterien in Form einer A-B-Studie getestet.
description: The CRM process generates an excellent addition to the common methods of impact research due to its continuous evaluation possibilities. To increase its full potential an open-source-software is developed under supervision. Theoretical considerations for the relevant influencing factors of conversation evaluation, as well as the speaking voice as a rhetorical factor, and listener’s capacity during the impact evaluation by a continuous measuring instrument are included in this work. The acceptance of this optimized CRM process is verified by a user-acceptance test in form of a use-case of speech science telecommunication research. Therefore, functionality and usability of the developed CRM software are tested with an A/B study regarding relevant speech science criteria.

description: In certain cases the communication time required to deterministically implement a nonlocal bipartite unitary using prior entanglement and LOCC (local operations and classical communication) can be reduced by a factor of two. We introduce two such "fast" protocols and illustrate them with various examples. For some simple unitaries, the entanglement resource is used quite efficiently. The problem of exactly which unitaries can be implemented by these two protocols remains unsolved, though there is some evidence that the set of implementable unitaries may expand at the cost of using more entanglement.

description: At the outbreak of war, the populations of Britain and Ireland understood that values such as national honour, liberty, and the rights of small nations were at stake. It was therefore necessary to mobilize in order to counter Germany’s aggression. People understood the war as a moral crusade. This language was both echoed in official discourse and restated in layman’s terms. It also manifested itself in positive and negative self-mobilized public behaviour. While the four and a half year conflict put unprecedented strain on civilians and triggered an armed rebellion in Dublin in 1916, the vast majority of people continued to believe that the war was worth fighting and that Germany had to be defeated.

description: The dual fluid description for a general cutoff surface at radius r=r_c outside the horizon in the charged AdS black brane bulk space-time is investigated, first in the Einstein-Maxwell theory. Under the non-relativistic long-wavelength expansion with parameter ε, the coupled Einstein-Maxwell equations are solved up to O(ε^2). The incompressible Navier-Stokes equation with external force density is obtained as the constraint equation at the cutoff surface. For non-extremal black brane, the viscosity of the dual fluid is determined by the regularity of the metric fluctuation at the horizon, whose ratio to entropy density η/s is independent of both the cutoff r_c and the black brane charge. Then, we extend our discussion to the Gauss-Bonnet-Maxwell case, where the incompressible Navier-Stokes equation with external force density is also obtained at a general cutoff surface. In this case, it turns out that the ratio η/s is independent of the cutoff r_c but dependent on the charge density of the black brane.

description: This article accounts for two puzzling paradoxes. The first paradox is the simultaneous absence and presence of attitude polarization, the fact that global attitude polarization is relatively rare, even though pundits describe it as common. The second paradox is the simultaneous presence and absence of social polarization, the fact that while individuals experienced attitude homogeneity in their interpersonal networks, their networks are characterized by attitude heterogeneity. These paradoxes give rise to numerous scholarly arguments. By deploying a formal model of interpersonal influence over attitudes in a context where individuals hold simultaneous positions on multiple issues we show why these arguments are not mutually exclusive and how they meaningfully refer to the same social setting. It follows that the results from this model provide a single parsimonious account for both paradoxes. The framework we develop may be generalized to a wider array of problems, including classic problems in collective action.

description: Recognizing the actual structure of sexual networks is critical for modeling the potential for disease transmission, if disease is spread via sexual contact. This article reports the structure of an adolescent romantic and sexual network in a population of over 800 adolescents residing in a mid-sized town in the mid-western United States. Precise images and measures of network characteristics are derived from reports of relationships that occurred over a period of eighteen months between 1993 and 1995. We compare the structural characteristics of the observed network to simulated networks governed by similar constraints on the distribution of ties, and show that the observed structures differ radically from the randomly generated networks. Specifically, we find that real sexual and romantic networks are characterized by much longer contact chains and far fewer cycles. We then identify a set of micro-mechanisms that generates networks with similar structural features to the observed network. Implications for disease transmission dynamics and social policy are explored.
The role of different negatively charged layers in Ca10(Fe1-xPtxAs)10(Pt3+yAs8) and superconductivity at 30 K in electron-doped (Ca0.8La0.2)10(FeAs)10(Pt3As8)

description: The recently discovered compounds Ca10(Fe1-xPtxAs)10(Pt3+yAs8) exhibit superconductivity up to 38 K, and contain iron arsenide (FeAs) and platinum arsenide (Pt3+yAs8) layers separated by layers of Ca atoms. We show that high Tc's above 15 K only emerge if the iron-arsenide layers are at most free of platinum-substitution (x \rightarrow 0) in contrast to recent reports. In fact Pt-substitution is detrimental to higher Tc, which increases up to 38 K only by charge doping of pure FeAs layers. We point out, that two different negatively charged layers [(FeAs)10]n- and (Pt3+yAs8)m- compete for the electrons provided by the Ca2+ ions, which is unique in the field of iron-based superconductors. In the parent compound Ca10(FeAs)10(Pt3As8), no excess charge dopes the FeAs-layer, and superconductivity has to be induced by Pt-substitution, albeit below 15 K. In contrast, the additional Pt-atom in the Pt4As8layer shifts the charge balance between the layers equivalent to charge doping by 0.2 electrons per FeAs. Only in this case Tc raises to 38 K, but decreases again if additionally platinum is substituted for iron. This charge doping scenario is supported by our discovery of superconductivity at 30 K in the electron-doped La-1038 compound (Ca0.8La0.2)10(FeAs)10(Pt3As8) without significant Pt-substitution.

Therefore, their neuroprotective effects are examined in the model organism Caenorhabditis elegans. In different C. elegans models for Parkinson’s, Alzheimer’s and Huntington’s disease an extract of olive leaves shows neuroprotective properties and reduces neurodegeneration and plaque-accumulation. It improves the physiology of the animals. Tested compounds of olive leaves (oleuropein, oleanolic acid, hydroxytyrosol and tyrosol) and other tested plant derived extracts induce neuroprotective effects in C. elegans models for neurodegenerative diseases, too. The plant derived extracts and compounds examined here are promising candidates for prevention and therapy of Parkinson’s, Alzheimer’s and Huntington’s disease. However, further investigations on underlying mechanisms are needed.

description: The First World War was not only the precondition of the rise of fascist movements in a general way: more definitely, the fascists presented themselves as the heirs of the trench combatants. German ''Sturmtruppen'' and Italian ''arditi ''were chosen by the right-wing movements of National Socialism and Fascism as models for a new “political soldier”; they also became part of the mythology created by the regimes to strengthen popular consent. The militias of both movements took over symbols and practices of the stormtroopers in order to contrast themselves to the political status quo. After the access to power, the heritage of the war was adopted by the symbolic systems of reference of the regimes as a unifying and legitimizing factor, although in a secondary rank.

description: We use numerical simulations to study the effects of the patchiness of a partly reionized intergalactic medium (IGM) on the observability of Ly-alpha emitters (LAEs) at high redshifts (z ~ 6). We present a new model that divides the Ly-alpha radiative transfer into a (circum-)galactic and an extragalactic (IGM) part, and investigate how the choice of intrinsic line model affects the IGM transmission results. We use our model to study the impact of neutral hydrogen on statistical observables such as the Ly-alpha restframe equivalent width (REW) distribution, the LAE luminosity function and the two-point correlation function. We find that if the observed changes in LAE luminosity functions and equivalent width distributions between z ~ 6 and z ~ 7 are to be explained by an increased IGM neutral fraction alone, we require an extremely late and rapid reionization scenario, where the Universe was ~ 40 % ionized at z = 7, ~ 50 % ionized at z = 6.5 and ~ 100 % ionized at z = 6. This is in conflict with other observations, suggesting that intrinsic LAE evolution at z > 6 cannot be completely neglected. We show how the two-point correlation function can provide more robust constraints once future observations obtain larger LAE samples, and provide predictions for the sample sizes needed to tell different reionization scenarios apart.

 Distribution in Iran – Fars, Alborz, Kerman, Kermanshah and Yazd provinces (Akrami and Shahedi 2020).
 Zoogeographical distribution – Pantropical (frequent) and Subtropical.
 Remarks
 In the study of the oribatid mite fauna of Sistan and Baluchestan province, totally, 23 species from 20 genera and 15 families were collected, of which two species represented new records for the mite fauna of Iran; it should be noted that all species are recorded for the first time from Sistan and Baluchestan province. According to the results, Cosmochthoniidae, Haplochthoniidae and Galumnidae (each with 3 species), Cosmochthonius (with 2 species), and Haplochthonius (with 3 species) are the families and genera with the highest number of species. A rare species, Thamnacarus smirnovi, previously known from Central Asia, is reported for the second time for the fauna of Iran. The knowledge about the diversity and distribution of the oribatid mites of Sistan and Baluchestan province is limited and more research is needed for a better understanding of the diversity of Iranian oribatid mites. Among them, the finding of Verachthonius cf. laticeps (Strenzke, 1951) is the first record for fauna of Iran. We give an additional description and new illustrations of the adult of this species based on material collected from Sistan and Baluchestan province, Iran.

description: It has been argued that adolescents who get pregnant often do not sufficiently appreciate its unfavorable consequences, and that prevention programs should target participants' attitudes towards pregnancy. This study tests whether the nature and certainty of sexually active adolescent girls' attitudes towards pregnancy influence their contraceptive consistency and risk of pregnancy. It also tests whether attitudes towards contraception influence contraceptive consistency. Data are drawn from the National Longitudinal Study of Adolescent Health, a nationwide prospective study of adolescents in grades 7-12. Attitudes towards pregnancy, attitudes towards contraception, knowledge about fertility and other individual characteristics are included in a multivariate model of contraceptive consistency. Those variables, as well as contraceptive consistency itself, are then included in a multivariate model of pregnancy. Net of other factors, girls' attitudes towards getting pregnant did not affect whether they actually became pregnant. However, ambivalence about pregnancy made girls less likely to use contraception. Girls who were most opposed to pregnancy did not differ in contraceptive consistency from those least opposed. Implications for pregnancy prevention efforts are discussed.

description: The authors consider social, genetic, evolutionary, and hormonal transfer hypotheses for same-sex romantic preferences of adolescent (N=5,552) sibling pairs drawn from a nationally representative sample. They show that male but not female opposite-sex twins disproportionately report same-sex attraction; and that the pattern of concordance of same-sex preference among siblings is inconsistent with a simple genetic influence model. Their results provide substantial support for the role of social influences, reject the hormone transfer model, reject a speculative evolutionary theory, and are consistent with a general model that allows for genetic expression of same-sex attraction under specific, highly circumscribed, social conditions.

description: From the cradle to the grave, popular religion formed a necessary and vital, if analytically messy, part of the human experience of the Great War. The war had the potential to atomize and alienate religious believers, but lived religion had the power to deepen traditional bonds of identity and provide comfort, hope, and meaning. This article examines popular religion in terms of the variety of religious beliefs and practices of large numbers of people. Often contrasted with “official” religion, popular religion was not inherently antithetical to authority, as demonstrated by the large numbers of faithful who, in their moments of deepest personal need, used official prayers, like the “Our Father” (the Lord’s Prayer), or liturgical aids, such as rosaries. Popular religious beliefs were essential to the hearts and minds of billions of people across the globe.

Synthesis and biological activity of chloroquine ferrocenyl conjugates for the treatment of malaria
Creators: name: Salas Fernandez, Paloma
Publisher: name: University of British Columbia
Year: 2013

description: Malaria is one of the main causes of mortality and morbidity in the world, endangering billions and affecting millions of people each year. Resistance to common antimalarial drugs has proven to be a challenging problem in malaria control. In an attempt to develop an effective and affordable treatment for malaria, ferrocenyl conjugates incorporating a common antimalarial drug such as chloroquine have been developed. Based on the previous successes of organometallic derivatives of classical pharmacophores, a series of chloroquine-bridged ferrocenyl derivatives was synthesized. These novel compounds present an unprecedented binding mode of chloroquine to the ferrocene moiety, through the bridging of the two Cp rings. The structural effects of this type of conjugation of chloroquine and ferrocene were studied by NMR spectroscopy and crystal structure determination. These compounds were studied along with the monosubstituted ferrocenyl analogs and the organic components in order to compare the effects of the substitution on their biological response. The antiplasmodial activity of these sets of compounds was evaluated against the chloroquine-sensitive (D10) and the chloroquine-resistant (D2d and K1) malaria parasite (Plasmodium falciparum) strains. Additionally, their biological activity was assessed using a number of in vitro assays. Biological and physical properties were correlated to the antimalarial activity. All compounds were active against the tested parasite strains. The presence of the ferrocene significantly improved the antiplasmodial action, when compared to chloroquine, against the drug-resistant parasite strains. While the chloroquine-bridged ferrocenyl derivatives were in general less active than the monosubstituted ferrocenyl analogs, they retained activity in the drug-resistant strain to a greater extent. Their particular conformation, compact size and lipophilicity/hydrophilicity balance could be providing them with the structural characteristics needed to escape the mechanisms responsible for resistance. Additionally, two strategies for drug design were applied: multiple-loading and multifunctional therapy approaches. Ferrocenyl compounds loaded with two molecules of chloroquine and mefloquine were synthesized and characterized. Similarly, ferrocenyl derivatives of chloroquine and mefloquine were further derivatized with a monossacharide molecule. The double-loaded compounds are the first few examples of their kind. The multifunctional conjugates improved the antimalarial action of the ferrocenyl quinoline derivatives.

description: The 7.8 eV nuclear isomer transition in 229 Thorium has been suggested as an etalon transition in a new type of optical frequency standard. Here we discuss the construction of a "solid-state nuclear clock" from Thorium nuclei implanted into single crystals transparent in the vacuum ultraviolet range. We investigate crystal-induced line shifts and broadening effects for the specific system of Calcium fluoride. At liquid Nitrogen temperatures, the clock performance will be limited by decoherence due to magnetic coupling of the Thorium nucleus to neighboring nuclear moments, ruling out the commonly used Rabi or Ramsey interrogation schemes. We propose a clock stabilization based on counting of flourescence photons and present optimized operation parameters. Taking advantage of the high number of quantum oscillators under continuous interrogation, a fractional instability level of 10^{-19} might be reached within the solid-state approach.

description: Drawing on a remarkable data set compiled from ships' logs, journals, factory correspondence, ledgers, and reports that provide unusually precise information on each of the 4,572 voyages taken by English traders of the East India Company (hereafter EIC), the authors describe the EIC trade network over time, from 1601 to 1833. From structural images of voyages organized by shipping seasons, they map the (over time and space) emergence of dense, fully integrated, global trade networks: of globalization before globalization. The paper shows that the integration of the world trade system under the aegis of the EIC was the unintended by-product of systematic individual malfeasance (private trading) on the part of ship captains seeking profit from internal Eastern trade.

description: Alkali metal salts of tris(benzenediolato)phosphate [1]–, K[1] and Na[1], were prepared and examined as halide abstraction reagents. Compound K[1] reacts with (dppp)PdCl₂ [dppp = 1,3-bis(diphenylphosphino)propane] (1:1 ratio) or [(cod)RhCl]₂ (2:1 ratio) to afford [(dppp)Pd(μ-Cl)]₂[1]₂ and (cod)Rh[1], respectively. Brønsted acids H(DMSO)₂[1] and H(DMF)₂[1] were isolated as crystalline solids. The basicity of [1]– was examined using IR spectroscopy and determined to be comparable to [BF4]–. Brønsted acid H(DMF)₂[1] is effective in the protonolysis of late transition metal-alkyl bonds. Its stoichiometric reaction with (dppe)PdMe₂ [dppe = 1,2-bis(diphenylphosphino)ethane] affords either [(dppe)Pd(NCMe)Me][1] (1:1 ratio) or [(dppe)Pd(NCMe)₂][1]₂ (1:2 ratio). Brønsted acid H(DMF)₂[1] initiates the cationic polymerization of n-butyl vinyl ether at 17 °C to afford moderate molecular weight poly(n-butyl vinyl ether) (Mn = 10,000 g mol-¹, PDI = 2.80). Brønsted acids of tris(tetrachlorobenzenediolato)phosphate [2]–, H(OEt₂)₂[2] and H(OEt₂)(NCMe)[2], were isolated as crystalline solids. Brønsted acid H(OEt₂)₂[2] was shown to be an effective initiator for the cationic polymerizations of n-butyl vinyl ether, styrene and isoprene. High molecular weight poly(n-butyl vinyl ether) was isolated from polymerization at –78 °C (Mn = 122,000 g mol-¹, PDI = 1.19). Atactic polystyrene of moderate molecular weight was isolated from polymerization at –50 °C (Mn = 55,400 g mol-¹, PDI = 1.62). Moderate molecular weight trans-polyisoprene was isolated from polymerization at –38 °C (Mn = 77,000 g mol-¹, PDI = 1.34). Poly(methylenephosphine) and poly(methylenephosphine) oxide were coated onto paper sheets made from thermomechanical pulp. TAPPI (Technical Association of Pulp and Paper Industry) Standard Method T461 cm-00 was used to evaluate the flame retardant properties of the polymers. Paper samples coated with the phosphorus-based polymers exhibited a higher degree of charring when compared to untreated paper and were comparable to paper treated with the monobasic ammonium phosphate standard. The microstructure of the 1-(2,2,6,6-tetramethylpiperidinyloxy)-1-phenylethane initiated poly(methylenephosphine) was examined by NMR spectroscopy. Evidence suggests the occurrence of 1,5-hydrogen abstraction rearrangement during the propagation step of polymerization. The unexpected microstructure was modeled using PhCH₂P(Mes)CHPh₂.

description: Post-war Italy was the only country that proved unable to use victory as a rhetorical device to consolidate its political system. Internal divisions rendered the old liberal ruling classes incapable of closing ranks in response to the post-war socio-economic crisis, which was soon to lead to the turmoil of the ''biennio rosso'' (1919-1920). The ineptitude of the liberal elites was compounded by their refusal to contemplate an alliance with the Italian Socialist Party or with the Italian Popular Party, the two new mass parties to have loomed large on the post-war political scene, a stance reflecting the liberal reluctance to envisage the necessary transition to a democracy featuring modern political parties. In this fashion, the Italian ruling classes paved the way for the seizure of power by a radical nationalism which then led to fascism, a political force forged in the experience of war.

description: After a promising start, academic historiography of the First World War in Belgium fell silent after 1928. There was nothing that resembled an academic field of World War I studies in Belgium for decades. Two reasons might be the strength of Flemish national historiography and the enduring dominance of the Second World War. A remarkable shift occurred in the late 1990s, leading up to the frantic mobilization in 2014. This shift was not a generational occurence, but a convergence of separate decisions. This article hypothesizes that the underlying context was the end of the "golden era" of Belgian World War II historiography after the commemorative year 1995. This created the space for an academic field of World War I historiography.

Promising the Future: Virginity Pledges as They Affect Transition to First Intercourse

description: Since 1993, in response to an organized social movement sponsored by the Southern Baptist Church, well over two and a half million adolescents have taken public "virginity" pledges, in which they promise to abstain from sex until marriage. This paper explores the effect of virginity pledges on the transition to first intercourse. On one hand, we show that adolescents who pledge, controlling for all of the usual characteristics of adolescents and their social contexts that are associated with the transition to sex, are much less likely than adolescents who do not pledge, to have intercourse. The delay effect is substantial and almost impossible to erase. Taking a pledge delays intercourse for a long time. On the other hand, the pledge effect depends on age. Pledging does not work for adolescents at all ages. Second, pledging delays intercourse only in contexts where there are some, but not too many, pledgers. Too few, and too many, pledgers in the adolescent world can negate the pledge effect. The pledge works because it is embedded in an identity movement. Consequently, like other identity movements, the pledge identity is relatively fragile and meaningful only in contexts where it is at least partially non-normative. Consequences of pledging are explored for those who break their promise. Promise breakers are less likely to use contraception at first intercourse.

description: Seemingly endless tinkering and adjustment of the structure of education in the United States over the past century has led to the adoption of different school forms at different times. Currently the middle school is the dominant form of schooling for the middle years of education; however, the middle school is a relatively new form that replaced the junior high school, which itself replaced previous schooling forms. Despite the rhetoric of policymakers and practitioners, little research has considered what school forms work for what kinds of adolescents across what dimensions. In this article, we show that for both academic and non-academic outcomes, how school systems structure the transition from 8th to 9th grade makes almost no difference. Where differences appear, they are small and point to the benefits of school transitions for providing fresh starts to adolescents in socially difficult situations. The policy implications are correspondingly clear: the optimal school structure for any school district is the one that maximizes building space, reduces crowding, and achieves administrative rationality.
14 Ceti: A probable Ap-star-descendant entering the Hertzsprung gap

description: 14 Ceti is a subgiant star of F spectral class that displays variations in the S-index of its CaII H & K lines and an X-ray emission that is stronger than the mean observed for its spectral class, which may be due to some magnetic activity. We attempt to Zeeman-detect and study the magnetic field of 14 Ceti and to infer its origin. We used the spectropolarimeter Narval at the Telescope Bernard Lyot, Pic du Midi Observatory, and the least squares deconvolution method to create high signal-to-noise ratio Stokes V profiles. We derived the surface-averaged longitudinal magnetic field Bl. We also measured the S-index, and the radial velocity for each observation. 14 Ceti is Zeeman-detected for the 30 observed dates spanning from August 2007 to January 2012. The average longitudinal magnetic field does not reverse its sign, reaches about -35 G, and shows some month-long-timescale variations in our 2008 and 2011-2012 observations. The S-index follows the same long-term trend as Bl. 14 Ceti is confirmed as a single star without H-K emission cores. The strength of the observed surface magnetic field of 14 Ceti is one order of magnitude greater than the observed one for late F main-sequence stars, and is comparable to the values measured in the active late F pre-main-sequence star HR 1817. On the other hand, taking into account the post-main-sequence evolution of an Ap star, an oblique rotator model can explain the strength of the magnetic field of 14 Ceti. The variations with a timescale of months observed for both the Bl and S-index could be due to the rotation. The most probable scenario to explain our observations appears to be that 14 Ceti is the descendant of a cool Ap star .

description: Ground states of spin lattices can serve as a resource for measurement-based quantum computation. Ideally, the ability to perform quantum gates via measurements on such states would be insensitive to small variations in the Hamiltonian. Here, we describe a class of symmetry-protected topological orders in one-dimensional systems, any one of which ensures the perfect operation of the identity gate. As a result, measurement-based quantum gates can be a robust property of an entire phase in a quantum spin lattice, when protected by an appropriate symmetry.

description: Using a recently developed method combining a nonspherical self-interaction corrected LDA+$U$ scheme and an on-site multi-body Hamiltonian [Phys.\ Rev.\ B 83, 085106 (2011)], we calculate the crystal field parameters and crystal field (CF) excitation levels of $f$-element dioxides in the fluorite structure with $f^{n}$ electronic configurations, including $n=1$ (PaO$_{2}$, PrO$_{2}$), $n=2$ (UO$_{2}$), $n=3$ (NpO$_{2}$), and $n=4$ (PuO$_{2}$). It is shown that good agreement with experimental data (within approximately 10 to 20 meV) can be obtained in all cases. The properties of the multi-electron CF ground states are analyzed.

description: At the end of the war, all the belligerent countries had to face the dramatic consequences caused by a murderous and devastating conflict. France was no exception, especially as the majority of the battles on the western front occurred on its ground. After the Armistice, the nation thus entered into a process of reconstruction which, in reality, was conceived as early as 1914-1915. In this context, the role of the state was at stake, as well as its prerogatives and the consequences of reconstruction on the French economy.

description: We approximately solve the Dirac equation for the inversely quadratic Yukawa (IQY) potential including a Coulomb-like tensor potential with arbitrary spin-orbit coupling quantum number . In the framework of the spin and pseudospin (pspin) symmetry, we obtain the energy eigenvalue equation and the corresponding eigenfunctions in closed form by using the Nikiforov-Uvarov method. The numerical results show that the Coulomb-like tensor interaction removes degeneracies between spin and pspin state doublets.
