background: tuberculosis (tb) is still a major cause of morbidity and mortality in both developed and developing countries. delay in accessing tuberculosis care is associated with the highest densities of mycobacterium tuberculosis (m. tuberculosis) bacilli on sputum smears. objectives: the current study aimed to determine the extent of delay, and the major health system contributing factors to...

INTRODUCTION The aim of this study was to obtain Ages and Stages Questionnaire (ASQ) scores from the background population so that these may be used as a reference group to extremely preterm children at nine and 18 months of corrected age. MATERIAL AND METHODS A total of 298 children were randomly chosen among the Danish population in three different groups: 9-, 18- and 21 month-old children....

Ionospheric propagation effects have a significant impact on the signal properties of SAR observations, especially at low operation frequencies. Dispersion, group delay, Faraday Rotation (FR), and phase shifts are all a function of the socalled Total Electron Content (TEC), the operating frequency and the system bandwidth. In order to choose the right acquisition time with lower ionospheric imp...
