Nonlinear theory has predicted that wave-wave coupling from different band electromagnetic ion cyclotron (EMIC) waves can occur in multiple-ion plasmas. However, no direct observational evidence been reported yet. Here we present multiple substructures on the frequency spectrum of EMIC with observations Van Allen Probes. Some are demonstrated to be excited by nonlinear interactions between pree...

BACKGROUND Interpretation of Leprosy as a sickness differs among society. The set of beliefs, knowledge and perceptions towards a disease play a vital role in the construction of stigma towards a disease. The main purpose of this study was to explore the extent and correlates of the perceived stigma towards leprosy in the community living close to the leprosy colony in Non Somboon region of Kho...

During the recovery phase of a magnetic storm, fluxes of relativistic (> 1 MeV) electrons in the inner magnetosphere (3 ≤ L ≤ 6) increase to beyond pre-storm levels, reaching a peak about 4 days after the initiation of the storm. In order to account for the generation of these “killer electrons”, a model is presented primarily based on stochastic acceleration of electrons by enhanced whistler-m...

The banded structure of electromagnetic ion cyclotron (EMIC) wave spectra and their resonant interactions with radiation belt electrons depend on the cold composition. However, there is a great deal uncertainty in composition inner magnetosphere due to difficulties direct flux measurements. Here, we show that hydrogen helium band are most consistent oxygen few percent. Less than 10% intensity h...

Wave growth of electromagnetic ion cyclotron (EMIC) emissions observed in the outer magnetosphere is mainly controlled by compression events resulting from solar wind dynamic pressure pulses. During such wave expected to be maximum close magnetopause. In previous studies, distribution EMIC waves was analyzed according their distance Earth, which inadequate for studying magnetopause region. We m...

Purpose This study aims to identify people’s perceptions of what behaviourally differentiates effective managers from ineffective within a South Korean (SK) public sector organization, and the extent which findings are similar or different those an equivalent previous in SK private sector. Design/methodology/approach Adopting “pragmatic approach” assuming post-positivist ontology constructivist...

Large numbers of theory and observation studies have been conducted on electromagnetic ion cyclotron (EMIC) waves occurring in Earth’s magnetosphere. Numerous shown that accurately specifying the ions ionospheric origin their composition can greatly improve understanding magnetospheric EMIC waves, specifically generation, properties, effects plasma populations. With launch operations multiple r...

INTRODUCTION To identify sociocultural determinants of self-reported condom use and HIV testing and examine variables related to accessibility, motivation and obstacles among men who have sex with men (MSM) in Jordan. DESIGN Cross-sectional study among MSM who were identified through services of a local non-governmental organization (NGO). METHODS Respondents were studied with a semi-struct...
