Despite an ever-expanding body of literature on Adès's engagement with the music of the past, his use of traditional formal models has attracted little critical comment. That which does exist privileges the relatively straightforward surface articulation of his musical forms over more nuanced accounts. In the case of Adès's sonata forms, this has had at least two consequences for our understanding of his music: first, that too strong an emphasis on syntactical groupings occludes what is happening discursively in the music; and second, that ‘textbook’ models are not the only formal tradition with which Adès's sonata forms engage. Rather, his sonatas bear traces of a rotational model that recalls the examples of Janáček and Sibelius. This article considers how Adès's sonata forms can be constituted not as neo-classical prefabrications but, a posteriori, as a practice that emerges across his career – from the Chamber Symphony and …but all shall be well to the Piano Quintet and Concerto for Piano and Orchestra – from an interaction between traditional syntactical groupings, thematic procedures and tonal plots.

In this study, the two-to-one internal resonance between the first two rotational modes of planetary gear trains (PGTs) is investigated. A purely rotational model is applied considering mesh stiffness variations, tooth separations, and tooth profile modifications (TPMs). Semi-analytical solutions for the internal resonance case are obtained using the method of multiple scales (MMS). The solution equations indicate that the mesh stiffness variations and tooth separations are the main factors causing internal resonance. A validation of the MMS was performed by numerical integration (NI). The results from an example analysis indicate that there exists an internal resonance phenomenon in the case of ωN+2 ≈ ω2, where ω2 and ωN+2 are the natural frequencies associated with the rotational modes, and N is the number of planet gears. Internal resonance in PGTs causes chaos, and part of the energy is transmitted from the ring gear to the sun gear through shocks. Proper TPMs that eliminate the tooth separations could suppress the internal resonance. The internal resonance, in turn, affects the optimal areas of the TPM magnitudes.

Problem formulation. The development of information and computer technologies is quite rapid. The realities of today are that higher education institutions must introduce new and effective teaching methods and technologies that will help to improve the quality of education. The large-scale introduction of online technologies, various models of blended learning is relevant, which leads to fundamental changes in approaches to the organization of education in higher education institutions and in each discipline, especially the role of the audience classes and its effectiveness. Materials and methods. To address this aim, the following theoretical research methods were used in combination: analysis of pedagogical literature, systematization and generalization of research - to compare different approaches to the implementation of models of blended learning for students of higher pedagogical education. Results. The analysis of pedagogical literature and the conducted researches allowed to reveal the concept of "blended learning". Based on the existing domestic and foreign works, the existing models of blended learning are considered. The models of blended learning that are expedient to use when studying pedagogical disciplines in the institution of higher pedagogical education are analyzed, in particular "Flipped Model", "Rotation Model", "Lab Rotation Model". The advantages of using blended learning models, inverted learning models - for teachers and students are determined. Conclusions. The problem of implementing blended learning models is quite relevant and is of interest to many both scholars and practitioners. There is a wide range of models of blended learning, skillful application and combination of which makes the learning process interesting, modern and conscious, and the work of students productive, activates the educational and cognitive activities of higher education, motivates, teaches both independent and teamwork and promotes the development of creative abilities, research skills. It should be noted that the models "Flipped Model", "Rotation Model", "Lab Rotation Model" and others are tested in technical educational institutions, as well as in the teaching of exact sciences ("Physics", "Mathematics"), while in pedagogical institutions of higher education, especially in the training of future teachers of humanities, this problem requires more in-depth study and, possibly, modification of existing models. The prospect of further research involves the study, testing and analysis of various models of blended learning for students of higher pedagogical education, including the humanities.

Previously observed negative and positive parity states of 105Tc were studied in the framework of the particle-rotor model. Transition properties and experimental energies were compared to the predictions of model calculations. A systematic study of the evolution of the intruder π1/2+[413] band in the nuclear structure of odd-A technetium isotopes 95,97,99,101,103,105,107Tc is presented as well. The existence of this intruder band has been argued previously in 95,97,99,101,103Tc isotopes (partially populated) and fully observed and confirmed in 105Tc. It will be shown that changes in deformation and subsequently the position of the Fermi level, vis a vis the 1/2+[431] intruder orbital originating from the π(d5/2, g7/2) subshells, predominantly affect these systematic changes. All four interpreted experimental rotational bands are naturally predicted by the rotational model as bands build on states of good Ω originating from the 5/2+[422], 5/2–[303], 3/2–[301], and 1/2+[431] orbitals near the Fermi level in deformed 105Tc (strong coupling). Further experimental investigation about missing data are needed for those observed in low lying states in both 105Tc and 103Tc to confirm the presence of the 1/2–[301] rotational band that is well defined in lighter 95,97,99,101Tc isotopes.

In the context of the double folding optical model, the elastic and inelastic scattering of 9Be + 120Sn at Elab (9Be) = 31, 42 and 50 MeV and 9,10,11Be + 64Zn elastic scattering at Ec.m. = 24.5 MeV are investigated. Real folded potentials are generated using the DDM3Y interaction based on the suggested density distributions for the 9,10,11Be nuclei. The imaginary potential is taken in the traditional standard Woods–Saxon form. Coupled channel (CC) calculations using a rotational model are performed for 9Be inelastically scattered from 120Sn, leading to different 120Sn excited states. Successful reproduction of the observed angular distributions of the elastic and inelastic scattering differential cross-sections has been achieved using the derived potentials. Special attention is paid to the previously suggested ( $$ {3}_1^{-} $$ , Ex = 2.40 MeV) 120Sn excited state in order to present the contributions come from - $$ {3}_1^{-} $$ at 2.40030(5) MeV, $$ {2}_3^{+} $$ at 2.42090(3) MeV, $$ {2}_2^{+} $$ at 2.355383(24) MeV, and $$ {4}_1^{+} $$ at 2.465632(23) MeV—in forming the inelastic data observed at Ex = 2.41 MeV.

The need for research into the effective application of blended learning technologies and evaluation of its effectiveness for universities, students, teachers and society is determined by little experience in the use of blended technologies. Consequently, the aim of this study is to determine the effectiveness of blended learning models for student learning in view of the specifics of academic subjects. The research involved the methods of survey, simulation, pedagogical experiment, mathematical statistics. The following models were involved in the studies of the first- and fourth-year students of the higher educational institutions (HEIs) of Ukraine during the semester: rotational, Enriched Virtual model, and a combination of rotational model to study professional subjects and Enriched Virtual model to study humanities. Conclusions. The use of performance evaluation tools allows determining the state of readiness of the educational institution and students for involving blended technologies. Prospects. The results of the study can be compared with the following studies of the effectiveness of other blended learning models for students of different majors, determining the effectiveness of blended learning in general. Other levels of effectiveness of blended learning — operational, strategic management — are unresolved issues.

The essence of the concept of "blended learning", its main features, varieties, stages of implementation and models of realization are considered in the article. The analysis of modern researches of the problem of the use of blended learning in education, the identification on the basis of its results of the most optimal forms and models of use of "blended learning" is carried out. The expediency of using the classification of American researcher MB Horn, which identifies six models of blended learning, is indicated. Face-to-Face Driver. The educator personally teaches the bulk of the instructional material to the audience. An online course is added to the course as required, which is additional and traditional. "Rotation Model" ("rotational model"). There is a rotation of classroom and independent work of students online. Flexmodel. The course is mostly online. The teacher coordinates the activities of students through the network. Live contacts are made as needed. OnlineLab. The course is taught online, however, not at home alone, but in an equipped classroom under the guidance of a teacher. Self-BlendModel. Students choose courses to study online. The experience of blended learning in higher education is presented. The purpose and comparative capabilities of the common LMS (Learning Management Systems) - Moodle and Google Classroom - are analyzed. Based on the analysis of scientific sources and modern pedagogical practice, it was concluded that blended learning should be used in higher education institutions.

The global health crisis has brought a radical change in many areas. This change was driven by increased use of technology to support a large number of processes. In this scenario, we developed the Human-Computer Interaction course in two phases. A first adaptation from face-to-face into online and a second one focused on a blended approach to solving the problems related to the hybrid rotational model. During this process, the Microsoft Teams tool has provided a useful space to improve communication among the teaching staff and the students.

A survey of even–even nuclei in the nuclear chart showed regularities in the values of the ratio Q ( 2 1 + ) / ( B ( E 2 ) for each nucleus for which independent measurements of both the electric quadrupole moment of the 2 1 + state, Q ( 2 1 + ) , and the reduced transition probability B ( E 2 ; 0 1 + → 2 1 + ) exist. As predicted by the rotational model, this ratio was found to be close to unity for the deformed nuclei in the rare-earth region. For non-rotational nuclei the absolute value of this ratio is almost always considerably lower. This latter observation can be interpreted within different models for different classes of nuclei as illustrated by a set of schematic IBA model calculations. A general mixing model and simple geometrical models are also suitable for collective non-rotational nuclei. Near magic nuclei a mechanism within the seniority scheme is compatible with the observed small value of R Q B .

Spectroscopic factors to low-lying negative-parity states in $^{11}$Be extracted from the $^{12}$B($d$,$^3$He)$^{11}$Be proton-removal reaction are interpreted within the rotational model. Earlier predictions of the $p$-wave proton removal strengths in the strong coupling limit of the Nilsson model underestimated the spectroscopic factors to the $3/2^-_1$ and $5/2^-_1$ states and suggested that deviations in the $1^+$ ground state of the odd-odd $^{12}$B due to Coriolis coupling should be further explored. In this work we use the Particle Rotor Model to take into account these effects and obtain a good description of the level scheme in $^{11}$B, with a moderate $K$-mixing of the proton Nilsson levels [110]1/2 and [101]3/2. This mixing, present in the $1^+$ bandhead of $^{12}$B, is key to explaining the proton pickup data., 5 Pages, 2 Figures, to be submitted to Phys. Rev. C

In a recent experiment, carried out at the Radioactive Isotope Beam Factory/RIKEN, the $^{25}\mathrm{F}(p,2p)^{24}\mathrm{O}$ reaction was studied at 270 MeV/A in inverse kinematics. Derived spectroscopic factors suggest that the effective core of $^{25}\mathrm{F}$ significantly differs from a free $^{24}\mathrm{O}$ nucleus. We interpret these results within the particle-rotor model and show that the experimental level scheme of $^{25}\mathrm{F}$ can be understood in the rotation-aligned coupling scheme with its $5/{2}_{1}^{+}$ ground state as the bandhead of a decoupled band. The excitation energies of the observed $1/{2}_{1}^{+}$ and $9/{2}_{1}^{+}$ states correlate strongly with the rotational energy of the effective core, seen by the odd proton, and allow us to estimate its ${2}^{+}$ energy at $\ensuremath{\approx}3.2\phantom{\rule{0.28em}{0ex}}\mathrm{MeV}$ and a moderate quadrupole deformation ${\ensuremath{\epsilon}}_{2}\ensuremath{\approx}0.15$. The measured fragmentation of the $\ensuremath{\pi}{d}_{5/2}$ single-particle strength is discussed, and some further experiments suggested.

Author(s): Macchiavelli, AO; Crawford, HL; Fallon, P; Lee, IY; Clark, RM; Campbell, CM; Cromaz, M; Morse, C; Santamaria, C | Abstract: Spectroscopic strengths for the 18Fg,m(d,p)F19 reactions to members of the ground-state band in F19 are interpreted in the rotational model. The analysis considers two different coupling schemes, namely, the strong and decoupled limits of the particle rotor model to describe the ground and isomeric states of F18, as well as the transitions to the ground-state band in F19. Our results, obtained using Nilsson amplitudes for the neutron levels 12[220], 32[211], and 52[202] calculated at a deformation ϵ2=0.32 are in agreement with the measurements and USDB shell-model calculations.

The article analyses the appropriate methodological approaches in which the ideas of forming and developing of flexible skills can be applied in seminars and tutorials in such disciplines as "Foreign language", "Foreign language in the professional sphere", "Business foreign language" implementing at the university. The formation and development of flexible skills in such disciplines on the one hand, as an independent learning goal, involves the development of a range of skills necessary for the implementation of various types of activities, and on the other hand, as a means of developing foreign-language communicative competence, increasing the students level of foreign-language socialization. Technologies for the development of critical thinking and problem-based learning, project activities, learning in collaboration, case studies, a rotational model of mixed learning. can be applied for the formation and development of flexible skills at the university.

BackgroundWelsh Ambulance Service NHS Trust (WAST) and Betsi Cadwaladr University Health Board (BCUHB) were jointly awarded Welsh Government Pacesetter funding to assess the viability of a rotational approach to the delivery of care. The three part rotation incorporates the WAST Clinical Contact Centre, solo responding and shifts in BCUHB primary care settings. Nine WAST Advanced Paramedic Practitioners (APPs) started their rotation in north Wales in June 2019, a further eight joined in September 2020. The Minnesota Satisfaction Questionnaire (MSQ) was one of a number of data collection items undertaken as part of a service evaluation to evaluate the impact of this Pacesetter project.MethodsAPP Satisfaction was measured using the Minnesota Satisfaction Questionnaire (MSQ), a standardised tool designed to measure an employee’s satisfaction with work and aspects of the workplace environment. It comprises a 100-item questionnaire, with each question aligned to one of 20 scales. The MSQ was completed by the first cohort of APPs nine months into their rotation, and by the second Cohort in their third month. APPs were asked to consider all aspects of the rotation.ResultsOverall, both cohorts demonstrated a high level of satisfaction, in particular questions associated with intrinsic satisfaction scored better than ones linked to extrinsic satisfaction. For both Cohorts, Social Service, Working Conditions and Activity were all in the top five scoring scales. Whereas, Authority and Supervision (Human Relations) were lower scoring scales for both Cohorts.The individual raw scores were slightly higher for Cohort II than I. Cohort II also demonstrated a wider range in standard deviation scores across the scales.ConclusionThe MSQ is a simple yet effective measure of assessing workplace satisfaction. For the current Cohorts of Pacesetter APPs, scores indicated a high level of satisfaction across all aspects of the rotation.

The concrete is an outstanding material with vast utilization in the civil construction area. The determination of nonlinear behavior of concrete is still a major challenge in structural engineering. In this study there were investigated three smeared cracking models used for numerical modeling of reinforced concrete beam: fixed, rotational and multidirectional. In order to validate the models, three experimental samples studied by Bresler & Scordelis (1963) and Alvares (1993) were selected and modeled using the software DIANA. The results indicated that the three adopted smeared crack models performed well and where capable of predicting the equilibrium path. However, to beams with shear rupture it was impossible to find acceptable solutions for the fixed model, whereas with the rotational model it was obtained major numerical instability in order to determine the equilibrium path after materializing the diagonal cracking. Keywords: reinforced concrete beams; smeared cracking models; finite element method.

A six-temperature dynamic model, modified in terms of vibrational-rotational transitions, has been used to describe the dynamic processes in TEA CO 2 lasers. Significant improvement in the predicted laser characteristics was obtained, taking into account the CO 2 molecules vibrational-rotational transitions. The coupled differential equations were numerically solved by the fourth order Runge–Kutta method. The simulated output characteristics of the laser have been compared with simple vibrational dynamics model and experimental data due to a homemade TEA CO 2 laser. It has been found that the best agreement with experimental results regards to the vibrational-rotational dynamic model.

In recent years, there has been increased recognition of the benefits of teaching by active learning. However, there is a paucity of experimental studies utilizing active learning in undergraduate radiology rotations, which is traditionally a passive learning experience. We designed a new radiology rotation that integrated teaching by active learning. We prospectively examined the efficacy of this new rotation compared to our standard rotation in terms of students' radiological competency and attitudes toward radiology, as well as impact on departmental efficiency.This was a prospective cohort study involving fourth year medical students completing a 1-week radiology rotation at our department between January and April 2018. One cohort completed a rotational model which incorporated active learning sessions (integrated cohort) while the remainder were taught using traditional passive learning methods (standard cohort). All participants completed a radiology examination before and after the rotation and were surveyed on their attitudes toward radiology.A total of 105 students enrolled in the study. The mean postrotation competency score obtained by the integrated cohort was significantly higher than that obtained by the standard cohort (82% vs 62%; P0.001). The integrated rotation freed up 7 hours of radiologists' time per week. While the students completing the integrated rotation had a more positive perception of radiology, they were no more likely to express a desire to pursue a career in radiology.The integration of active learning sessions into an undergraduate radiology rotation results in an improvement in students' postrotation radiological competency and attitudes toward radiology.

This study is aimed at exploring the innovative teaching and learning approach called Blended Learning approach to improve the academic performance of student teachers, which also enhances the quality education. Blended learning approach is an integration of both face-to-face and online learning. It is designed as orientation of program, lesson plan, analyzing educational resources, determining educational objectives, assigning EDMODO platform for teaching learning process, designing teaching learning process and tools for teaching of science. The present study consisted of 53 student teachers. The innovative teaching and learning approach of Blended Learning with rotational model were students learn in presence of teacher and internet platform was used in teaching the Experimental group which comprise 29 student teachers, while the Conventional method was used with the Control group which consists of 24 student teachers. The experiment lasted for eight weeks. The study findings revealed that there were significant differences at 0.05 level in the mean scores of the test in favor of the experimental group. The findings also pointed out that there were statistically significant differences at 0.05 level in the participants’ pedagogical performance level before and after implementing the Blended learning method of teaching in favor of the post application (Awad Soliman Keshta, 2013). This was endorsed to the Blended Learning Program in teaching of science program. In the light of the study results, it is suggested that education stakeholders should adopt the innovative teaching method as blended learning method in teaching and learning process at teacher education level and conduct workshops for teachers to enhance teaching learning process. This integration of technology tool creates effective learning environment and promote self -learning which in turn improves student teachers pedagogical performance level.

Cross sections for elastic and inelastic scattering of the weakly bound $^{9}\mathrm{Be}$ nucleus on a $^{120}\mathrm{Sn}$ target have been measured at seven bombarding energies around and above the Coulomb barrier. The elastic angular distributions are analyzed with a four-body continuum-discretized coupled-channels (CDCC) calculation, which considers $^{9}\mathrm{Be}$ as a three-body projectile ($\ensuremath{\alpha}+\ensuremath{\alpha}+n$). An optical model analysis using the S\~ao Paulo potential is also shown for comparison. The CDCC analysis shows that the coupling to the continuum part of the spectrum is important for the agreement with experimental data even at energies around the Coulomb barrier, suggesting that breakup is an important process at low energies. At the highest incident energies, two inelastic peaks are observed at 1.19(5) and 2.41(5) MeV. Coupled-channels (CC) calculations using a rotational model confirm that the first inelastic peak corresponds to the excitation of the ${2}_{1}^{+}$ state in $^{120}\mathrm{Sn}$, while the second one likely corresponds to the excitation of the ${3}_{1}^{\ensuremath{-}}$ state.

With the end of major combat operations in Afghanistan, how will the North Atlantic alliance maintain the unprecedented levels of interoperability developed over the last decade? One of the most effective means of building and maintaining interoperability�the forward-based presence of US military forces in Europe� has shrunk significantly over the last 25 years and is likely to shrink further in the coming years, meaning it will become increasingly difficult for American and European military forces to operate side by side. Nevertheless, the United States continues to look to its allies in NATO as the primary partners in maintaining and promoting common interests around the globe. Additionally, Washington seems more committed than ever to wielding force in a coalition context. In order to help remedy this seeming incongruity, Washington announced in early 2012 a plan to deploy rotationally several hundred troops from the United States to Germany for periodic exercises with European partners and allies. However, it remains unclear whether a rotational model will be sufficient to generate the level of interoperability necessary for US forces and those of its most capable European allies to work seamlessly across the range of military operations. The loss of tactical and operational interoperability threatens transatlantic strategic interoperability, and therefore risks decoupling European and American security policy. To mitigate these challenges, the article discusses several policy steps the United States should consider.

The most enigmatic feature of mature thylakoids of Angiosperms is the presence of piles of membranous discs forming the cylindrical structures known as grana. Although some models aim to elucidate their formation, until now the mechanism governing the architecture of thylakoid stacks remains obscure. In this work a new model is presented aiming to explain the way thylakoids stack. In comparison with previous models, this model proposes a dynamic mechanism for the rapid selfassembly of thylakoid stacks and their subsequent disassembly under the influence of a variety of physicochemical factors and is consistent with the evolutionary origin of these membranes and their ontogenetic continuity. The model proposes that, under the influence of attractive electrostatic forces, the membranes come closer in a parallel alignment and the photosystem II/light harvesting complexes migrate laterally forming circular aggregates. Finally the thylakoids rotate around the vertical axis of the superimposed aggregates, under the action of a torque.

This paper presents an approach of integrated translational and rotational control (ITRC) design for the final approach phase of rendezvous and docking on an ellipse orbit. First, considering the uncertainties, the integrated translation and rotation dynamics model is formulated, and backstepping scheme is used to design an ITRC law such that the states of the closed-loop system can converge near zero. Then, by taking into consideration the input dynamics, the integrated translational and rotational model is transformed into the form of interconnected system, and thus, the small-gain theorem can be utilized to guarantee the stability of the over all system. Stability analysis as well as simulation results shows the effectiveness of the presented approach.

Frank Gibson rose from humble beginnings to become one of the most respected bacterial physiologists of his era. His identification of the elusive branch-point compound in the pathway of aromatic biosynthesis served as an initiation point for a sustained period of investigation in which the genes, enzymes and intermediates in the various pathways to phenylalanine and tyrosine, the quinones, enterochelin and 4-aminobenzoate were identified and examined in detail. studies on the function of ubiquinone led to an examination of oxidative phosphorylation and to the F 1 F 0 -ATPase of the bacterium Escherichia coli . With Graeme Cox he established a group of researchers who in the 1980s applied the various techniques of microbial genetics to construct a molecular profile of the proteins, which constituted the F 0 membrane- embedded part of the F 1 F 0 -ATPase. This work resulted in the formulation in 1986 of a rotational model and the identification of several residues that could comprise a pore through which the protons, which drove the rotation, could pass. He trained many research students during his lifetime and was an exemplary role model. Outside the laboratory he lived a full life, being an ardent skier, scuba diver and tennis player to name but a few of his pursuits. He is survived by his wife Robin and their son, Mark; by Frances, the daughter from his first marriage; and by grandchildren Teresa, Luke and Simon. His first wife, Margaret, and their second daughter, Ruth (mother of Teresa, Luke and Simon), are both deceased.

[ES] En este trabajo se propone una estrategia de control de tracción para un vehículo eléctrico de cuatro ruedas, basada en observadores no lineales que permiten estimar la fuerza máxima que se puede transferir al suelo. El conocimiento de la fuerza máxima permite realizar un control del deslizamiento de los neumáticos de tracción, evitando que las ruedas patinen aún en superficies de baja adherencia. La estrategia propuesta permite además evitar que se produzca un momento de guiño no deseado en el vehículo cuando las condiciones de suelo a cada lado del mismo son diferentes. Con ello se logra mejorar la eficiencia y el control del vehículo, evitando posibles pérdidas de estabilidad que pueden resultar en riesgos para sus ocupantes. Tanto el observador como el control propuestos son diseñados en base a un modelo dinámico rotacional de la rueda y un modelo de fuerzas de brush. Se presentan resultados de simulación obtenidos empleando un modelo completo de vehículo sobre la plataforma Simulink/CarSim., [EN] A traction control strategy for a four-wheel electric vehicle is proposed in this paper. The strategy is based on nonlinear observers which allows estimating the maximum force that can be transmitted to the road. Knowledge of the maximum force allows controlling the slip of the driving wheels, preventing the wheel’s slippage in low-grip surfaces. The proposed strategy also allows to avoid the undesired yaw moment in the vehicle which occurs when road conditions on either side of it are dierent. This improves the eciency and the control of the vehicle, avoiding possible losses of stability that can result in risks for its occupants. Both the proposed observer and the control strategy are designed based on a dynamic rotational model of the wheel and a brush force model. Simulation results are obtained based on a complete vehicle model on the Simulink/CarSim platform., Este trabajo fue financiado por la Universidad Nacional de Rıo Cuarto, FONCyT-ANPCyT (Subsidio PICT-2014-2760) y CONICET (Subsidio PIP 2014-2016 GI 11220130100517CO).

In a physical basis of the unitary scheme, analytic formulas for the probabilities B(E2κL → κ′L′) and their isospin factors for the (λ0) and (λ2) representations of the SU(3) group were obtained for even-even nuclei. It was shown that the isospin correction must be taken into account at low L and in the case of off-diagonal transitions in κ. The results obtained in the unitary scheme are compared with the results of other models and with experimental data. At high L, the transition probabilities B(E2κL → κ′L′) are markedly smaller in the unitary scheme than in the rotational model, while, for L ≪ λ, these probabilities in the unitary scheme and in the rotational model are close.

We describe the low-lying negative parity states of 238U in terms of a Pb–Ne cluster model. The Pb core is in an excited 3− state and the relative orbital motion has angular momentum values L = 0, 2, 4, .... The two bodies interact through central and second rank tensor potentials, leading to four bands loosely labelled by the rotational model notation of Kπ = 0−, 1−, 2−, 3−. However, the coupling between core and cluster is of intermediate strength, leading to an irregular pattern of energy differences, in particular inverted doublets in the Kπ = 1− band. Remarkably, the main features of the predicted spectrum are borne out by experiment.

The objective of this evaluation was to review the role of the paediatric night sister in a large regional children’s unit in the south of England in the light of the NHS Modernisation Agency report, The Hospital At Night (Modernisation Agency, 2004). It aimed to compare and contrast the role of the traditional night sister with that of an internal rotational model. A single-site case study service evaluation was undertaken using non-participant observation of the night sister role over two full night shifts, a questionnaire, semi-structured interviews with night duty nursing and medical staff, and analysis of night sister diaries. Two full-time night sisters and 34 night nursing and medical staff took part. The review obtained a description and analysis of night sister roles, the views of staff towards the role of the night sister, an insight into enhanced skills acquisition of night sisters, and makes recommendations for future utilisation of the night sister role. Most respondents were very supportive of the traditional night sister role but were critical of the lack of collaboration between the night medical and nursing teams.

The energies of negative-parity levels based on two-particle states exhibit a nonlinear behavior at low spins versus the core-rotation energy because the alignment process has not yet been completed for them. This behavior of negative-parity levels in the low-spin region is satisfactorily described upon the inclusion of octupole-octupole interactions. This is demonstrated within the rotational model involving the Coriolis mixing of states for the even-even isotopes 162–168Hf.

As-received CoFeSiB amorphous wires with 128 μm diameter were electrochemically etched at constant voltage to obtain micro magnetoimpedance (MI) sensor. Wires with different diameters from 13 to 100 μm were obtained at various constant voltage and pH conditions. The diameters and surface properties of the wires were studied by scanning electron microscopy. It was found that the magnitude of the magnetoimpedance effect was first increased and then decreased with decreasing wire diameter. The thinnest wire obtained at pH 4 and 0.4 V, has a diameter of 13 μm and this wire shows a 4.95% variation in the magnitude of (ΔZ/Z)(%). The results were discussed on the basis of internal stress distribution and a simple magnetic moment rotational model.
