Satisfaction among patients attending oncology clinic in a tertiary hospital in South West, Nigeria

Objective: This study determined patients' satisfaction with health care received at the oncology clinic in a tertiary hospital in Lagos, South West of Nigeria.Methods: A descriptive cross-sectional study was carried out among patients attending the oncology clinic in Lagos State University Teaching Hospital, Ikeja, Lagos. A total of 143 patients were recruited using a systematic random sampling and interviewer administered questionnaire was used to collect data. Analysis was done using Statistical Package for Social Sciences (SPSS version 20). Test of significance was performed using a 95% confidence interval and the level of significant set at p = 0.05.Results: More than half 123 (86.1%) reported that they got the kind of service they wanted, 125 (87.5%) reported almost all their needs had been met. Majority (92.3%) of the respondents were satisfied with the level of care received while 2.8% were indifferent and 7 (5%) were dissatisfied. The level of satisfaction was statistically significantly associated with age, marital status, level of education and average monthly income (p<0.05).Conclusion: Majority of patients were satisfied with the health care services at the oncology clinic. Regular satisfaction survey is recommendedKeywords: Patient satisfaction, oncology, tertiary hospita

Multicanonical Multigrid Monte Carlo

To further improve the performance of Monte Carlo simulations of first-order phase transitions we propose to combine the multicanonical approach with multigrid techniques. We report tests of this proposition for the $d$-dimensional $\Phi^4$ field theory in two different situations. First, we study quantum tunneling for $d = 1$ in the continuum limit, and second, we investigate first-order phase transitions for $d = 2$ in the infinite volume limit. Compared with standard multicanonical simulations we obtain improvement factors of several resp. of about one order of magnitude.Comment: 12 pages LaTex, 1 PS figure appended.

Psychosocial functioning in adolescents with and without borderline personality disorder.

Little is known about the psychosocial functioning of adolescents with borderline personality disorder (BPD). The main objective of this paper is to compare the psychosocial functioning of a group of adolescents with BPD to a group of psychiatrically healthy adolescents. The present cross-sectional study included 104 adolescent inpatients with BPD, compared with 60 age-matched psychiatrically healthy comparison subjects. All participants were rigorously diagnosed using three semi-structured interviews: the Structured Clinical Interview for DSM-IV Childhood Diagnoses, the Revised Diagnostic Interview for Borderlines and the Childhood Interview for DSM-IV Borderline Personality. All subjects were also interviewed using the adolescent version of the Background Information Schedule to assess multiple facets of psychosocial functioning. Adolescents with BPD rated their relationships with their parents as significantly less positive, were more likely to date, but spent more time alone than their healthy counterparts. In addition, adolescents with BPD reported significantly more problems at work and school (i.e. lower frequency of having a good work or school history, higher frequency of being suspended or expelled from school) and significantly lower rates of participation in extra-curricular activities than their healthy counterparts. Taken together, the results of this study suggest that adolescents with BPD are more impaired in both the social and vocational areas of functioning than psychiatrically healthy comparison subjects. They might also suggest that an overlooked area of strength concerns their relationships with peers. Copyright © 2017 John Wiley & Sons, Ltd

Non-relativistic effective theory of dark matter direct detection

Dark matter direct detection searches for signals coming from dark matter scattering against nuclei at a very low recoil energy scale ~ 10 keV. In this paper, a simple non-relativistic effective theory is constructed to describe interactions between dark matter and nuclei without referring to any underlying high energy models. It contains the minimal set of operators that will be tested by direct detection. The effective theory approach highlights the set of distinguishable recoil spectra that could arise from different theoretical models. If dark matter is discovered in the near future in direct detection experiments, a measurement of the shape of the recoil spectrum will provide valuable information on the underlying dynamics. We bound the coefficients of the operators in our non-relativistic effective theory by the null results of current dark matter direct detection experiments. We also discuss the mapping between the non-relativistic effective theory and field theory models or operators, including aspects of the matching of quark and gluon operators to nuclear form factors.Comment: 35 pages, 3 figures, Appendix C.3 revised, acknowledgments and references adde

Dynamics of trapped bright solitons in the presence of localized inhomogeneities

We examine the dynamics of a bright solitary wave in the presence of a repulsive or attractive localized ``impurity'' in Bose-Einstein condensates (BECs). We study the generation and stability of a pair of steady states in the vicinity of the impurity as the impurity strength is varied. These two new steady states, one stable and one unstable, disappear through a saddle-node bifurcation as the strength of the impurity is decreased. The dynamics of the soliton is also examined in all the cases (including cases where the soliton is offset from one of the relevant fixed points). The numerical results are corroborated by theoretical calculations which are in very good agreement with the numerical findings.Comment: 8 pages, 5 composite figures with low res (for high res pics please go to http://www.rohan.sdsu.edu/~rcarrete/ [Publications] [Publication#41

Fundamental constants and tests of general relativity - Theoretical and cosmological considerations

The tests of the constancy of the fundamental constants are tests of the local position invariance and thus of the equivalence principle. We summarize the various constraints that have been obtained and then describe the connection between varying constants and extensions of general relativity. To finish, we discuss the link with cosmology, and more particularly with the acceleration of the Universe. We take the opportunity to summarize various possibilities to test general relativity (but also the Copernican principle) on cosmological scales.Comment: Proceedings of the workshop ``The nature of gravity, confronting theory and experiment in space'', ISSI, Bern, october 200

Interaction of N solitons in the massive Thirring model and optical gap system: the Complex Toda Chain Model

Using the Karpman-Solov''ev quasiparticle approach for soliton-soliton interaction I show that the train propagation of N well separated solitons of the massive Thirring model is described by the complex Toda chain with N nodes. For the optical gap system a generalised (non-integrable) complex Toda chain is derived for description of the train propagation of well separated gap solitons. These results are in favor of the recently proposed conjecture of universality of the complex Toda chain.Comment: RevTex, 23 pages, no figures. Submitted to Physical Review

A CsI(Tl) Scintillating Crystal Detector for the Studies of Low Energy Neutrino Interactions

Scintillating crystal detector may offer some potential advantages in the low-energy, low-background experiments. A 500 kg CsI(Tl) detector to be placed near the core of Nuclear Power Station II in Taiwan is being constructed for the studies of electron-neutrino scatterings and other keV-MeV range neutrino interactions. The motivations of this detector approach, the physics to be addressed, the basic experimental design, and the characteristic performance of prototype modules are described. The expected background channels and their experimental handles are discussed.Comment: 34 pages, 11 figures, submitted to Nucl. Instrum. Method

Menus for Feeding Black Holes

Black holes are the ultimate prisons of the Universe, regions of spacetime where the enormous gravity prohibits matter or even light to escape to infinity. Yet, matter falling toward the black holes may shine spectacularly, generating the strongest source of radiation. These sources provide us with astrophysical laboratories of extreme physical conditions that cannot be realized on Earth. This chapter offers a review of the basic menus for feeding matter onto black holes and discusses their observational implications.Comment: 27 pages.

Recent developments in planet migration theory

Planetary migration is the process by which a forming planet undergoes a drift of its semi-major axis caused by the tidal interaction with its parent protoplanetary disc. One of the key quantities to assess the migration of embedded planets is the tidal torque between the disc and planet, which has two components: the Lindblad torque and the corotation torque. We review the latest results on both torque components for planets on circular orbits, with a special emphasis on the various processes that give rise to additional, large components of the corotation torque, and those contributing to the saturation of this torque. These additional components of the corotation torque could help address the shortcomings that have recently been exposed by models of planet population syntheses. We also review recent results concerning the migration of giant planets that carve gaps in the disc (type II migration) and the migration of sub-giant planets that open partial gaps in massive discs (type III migration).Comment: 52 pages, 18 figures.
