Capture of slow antiprotons by helium atoms

A consistent quantum mechanical calculation of partial cross-sections leading to different final states of antiprotonic helium atom was performed. For the four-body scattering wave function, corresponding to the initial state, as well as for the antiprotonic helium wave function, appearing in the final tate, adiabatic approximations was used. Calculations were carried out for a wide range of antiprotonic helium states and incident energies of the antiproton. Obtained energy dependances of some cross sections show a rich low energy structure.Comment: 16 pages, 8 color pictures; the text, the bibliography, and the pictures were slightly correcte

Southern Africa in water crisis – A case study of the Pangara River water shortage, 1987–1996: Towards a resource-based conflict management and resolution perspective

This paper is organised in three parts. The first is an assessment of the nature of the environmental and regional weather patterns leading to predictable water shortages. This is followed by the case study of the Pangara River community. Analysed at the micro-level, as the community tried to grapple with the gradual onset of lack of water, it is hoped that the principles brought out can be anticipated at the regional level. The final part briefly draws on the earlier discussion putting forward suggestions and recommendations for the establishment of a regional mechanism for managing the water system

Faddeev calculations of the KˉNN\bar{K}NN system with chirally-motivated KˉN\bar{K}N interaction. I. Low-energy K−dK^- d scattering and antikaonic deuterium

A chirally-motivated coupled-channel $\bar{K}N$ potential, reproducing all low-energy experimental data on $K^- p$ scattering and kaonic hydrogen and suitable for using in accurate few-body calculations, was constructed. The potential was used for calculations of low-energy amplitudes of the elastic $K^- d$ scattering using Faddeev-type AGS equations with coupled $\bar{K}NN$ and $\pi \Sigma N$ channels. A complex $K^- - d$ potential reproducing the three-body $K^- d$ amplitudes was constructed and used for calculation of $1s$ level shift and width of kaonic deuterium. The predicted shift $\Delta E_{1s}^{K^- d} \sim -830$ eV and width $\Gamma_{1s}^{K^- d} \sim 1055$ eV are close to our previous results obtained with phenomenological $\bar{K}N$ potentials.Comment: 15 pages, 5 figures, 3 table

Short-range oscillators in power-series picture

A class of short-range potentials on the line is considered as an asymptotically vanishing phenomenological alternative to the popular confining polynomials. We propose a method which parallels the analytic Hill-Taylor description of anharmonic oscillators and represents all our Jost solutions non-numerically, in terms of certain infinite hypergeometric-like series. In this way the well known solvable Rosen-Morse and scarf models are generalized.Comment: 23 pages, latex, submitted to J. Phys. A: Math. Ge

Structure of the mirror nuclei 9^9Be and 9^9B in a microscopic cluster model

The structure of the mirror nuclei $^9$Be and $^9$B is studied in a microscopic $\alpha+ \alpha+ n$ and $\alpha+ \alpha+ p$ three-cluster model using a fully antisymmetrized 9-nucleon wave function. The two-nucleon interaction includes central and spin-orbit components and the Coulomb potential. The ground state of $^9$Be is obtained accurately with the stochastic variational method, while several particle-unbound states of both $^9$Be and $^9$B are investigated with the complex scaling method.The calculation for $^9$Be supports the recent identification for the existence of two broad states around 6.5 MeV, and predicts the $\frac{3}{2}^{-}_2$ and $\frac{5}{2}^{-}_2$ states at about 4.5 MeV and 8 MeV, respectively. The similarity of the calculated spectra of $^9$Be and $^9$B enables one to identify unknown spins and parities of the $^9$B states. Available data on electromagnetic moments and elastic electron scatterings are reproduced very well. The enhancement of the $E$1 transition of the first excited state in $^9$Be is well accounted for. The calculated density of $^9$Be is found to reproduce the reaction cross section on a Carbon target. The analysis of the beta decay of $^9$Li to $^9$Be clearly shows that the wave function of $^9$Be must contain a small component that cannot be described by the simple $\alpha+ \alpha+ n$ model. This small component can be well accounted for by extending a configuration space to include the distortion of the $\alpha$-particle to $t+p$ and $h+n$ partitions.Comment: 24 page

PENGARUH SPIRITUAL EMOTIONAL FREEDOM TECHNIQUE(SEFT)TERHADAP KECEMASAN, SATURASI OKSIGEN DAN KUALITAS TIDUR PASIEN PENYAKIT PARU OSBTRUKTIF KRONIK (PPOK)

Latar belakang: PPOK dapat mempengaruhi aspek sosial dan psikologis serta kesehatan fisik. Kecemasan, kehilangan kontrol dalam kemandirian, perubahan konsep diri serta hambatan pernapasan mengakibatkan terjadinya perubahan psikologis yang serius, termasuk ketakutan akan kematian dan depresi. Terdapat hubungan yang signifikan antara depresi dan kecemasan dengan kualitas tidur pasien penyakit kronik, semakin tinggi derajat depresi semakin buruk kualitas tidurnya. Spiritual Emotional Freedom Technique (SEFT) adalah terapi yang menggunakan unsur spiritual untuk mengurangi masalah psikologis dan fisik yang disebabkan oleh emosional atau psikosomatik. Tujuan penelitian ini menganalisis pengaruh SEFT tehadap kecemasan, saturasi oksigen dan kualitas tidur pasien PPOK.

Emotional Freedom Technique (EFT) for Physiological Symptoms, Pain, Anxiety Disorders and Depression: a Systematic Review

Introduction: All the emotions and mind is a form of energy, both positive and negative energy, has an influence on body functions. While the human body has the potential of natural healing, stress and other emotional problems can impede the healing process. Emotional Freedom Technique (EFT) is a form of psychological acupressure, based on the same energy meridians in traditional acupuncture to treat physical and emotional illness. Through this systematic review, researchers will discuss about the effectiveness of EFT as a therapy that can affect the improvement of the physiological and psychological. Methods: Search of journal articles was used PECOT framework in the database; Ebscho, Science Direct, Elseiver, Sage Journals, Scopus, ProQuest, and Pub Med with limitations of publication time is in the last 5 years (2013-2017). There was 17 International journals and researchers conducted review to all of those journals. Results: The overall stated that the Emotional Freedom Technique (EFT) as a therapy that may influence physiological symptoms, pain, anxiety disorders and depression. Conclusion: This systematic review strongly recommends the application of EFT as a method of cleansing the mind, focusing (such as meditation) and improving attitudes so as to have a better chance of coping with emotional problems

Effect of Spiritual Emotional Freedom Technique (SEFT) to Anxiety Patient Chronic Obstructive Pulmonary Disease (COPD)

Introduction: COPD can affect social and psychological aspects as well as physical health. Anxiety, loss of control in self-reliance, changes in self-concept and respiratory barriers result in serious psychological changes, including fear of death and depression.There is a significant relationship between depression and anxiety with sleep quality of chronic disease patients, the higher the degree of depression the worse the quality of sleep. Spiritual Emotional Freedom Technique (SEFT) is a therapy that uses spiritual elements to reduce psychological and physical problems caused by emotional or psychosomatic. Methods: This study use Quasy Experiment "with Pre-Post test group control design approach. The population of this study was the patient of COPD in dr. H. Koesnadi Hospital and Bhayangkara Hospital at Bondowoso. Sampling was done by simple random sampling technique according to inclusion criteria with total 68 patients. SEFT intervention performed 8 times for 1 month. Instrument for anxiety using HARS. Data analysis using Mann Whitney Test. Results: There was a significant difference in the level of anxiety (p 0,000) between before and after SEFT therapy. Conclusion: SEFT can reduce anxiety levels of COPD patients, if done regularly and sustainably. The intervention focuses on reducing emotional or psychosomatic psychological problem

Panel 6 : Vaccines

Objective. To review the literature on progress regarding (1) effectiveness of vaccines for prevention of otitis media (OM) and (2) development of vaccine antigens for OM bacterial and viral pathogens. Data Sources. PubMed database of the National Library of Science. Review Methods. We performed literature searches in PubMed for OM pathogens and candidate vaccine antigens, and we restricted the searches to articles in English that were published between July 2011 and June 2015. Panel members reviewed literature in their area of expertise. Conclusions. Pneumococcal conjugate vaccines (PCVs) are somewhat effective for the prevention of pneumococcal OM, recurrent OM, OM visits, and tympanostomy tube insertions. Widespread use of PCVs has been associated with shifts in pneumococcal serotypes and bacterial pathogens associated with OM, diminishing PCV effectiveness against AOM. The 10-valent pneumococcal vaccine containing Haemophilus influenzae protein D (PHiD-CV) is effective for pneumococcal OM, but results from studies describing the potential impact on OM due to H influenzae have been inconsistent. Progress in vaccine development for H influenzae, Moraxella catarrhalis, and OM-associated respiratory viruses has been limited. Additional research is needed to extend vaccine protection to additional pneumococcal serotypes and other otopathogens. There are likely to be licensure challenges for protein-based vaccines, and data on correlates of protection for OM vaccine antigens are urgently needed. Implications for Practice. OM continues to be a significant health care burden globally. Prevention is preferable to treatment, and vaccine development remains an important goal. As a polymicrobial disease, OM poses significant but not insurmountable challenges for vaccine development.Peer reviewe
