TL;DR: In this article, the authors examined the onset and end dates of the rainy season in the Amazon Basin for the period 1979-96, by averaging daily rainfall data from many stations and then constructing 5-day averages (pentads).
Abstract: Onset and end of the rainy season in the Amazon Basin are examined for the period 1979–96. The onset and end dates are determined by averaging daily rainfall data from many stations, and then constructing 5-day averages (pentads). Onset (end) is defined as the pentad in which rainfall exceeds (falls below) a given threshold, provided that average rainfall was well below (above) the threshold for several pentads preceding onset (end), and well above (below) the threshold for several pentads after onset (end). For the criteria chosen, the climatological onset progresses toward the southeast, arriving in mid-October, and then toward the mouth of the Amazon, arriving near the end of the year. The end dates are earliest in the southeast and progress toward the north, but withdrawal is slower than onset. The onset dates, however, are quite sensitive to changes in the threshold. If the threshold is doubled, for example, the sense of onset is reversed, with onset occurring toward the northwest. Changes i...

TL;DR: In this paper, the authors evaluate carbon taxes with regard to their competitiveness, distributional and environmental impacts and show that carbon taxes may be an interesting policy option and that their main negative impacts may be compensated through the design of the tax and the use of the generated fiscal revenues.

TL;DR: The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays as discussed by the authors, which combines a surface array to measure secondary particles at ground level together with a fluorescence detector to measure the development of air showers in the atmosphere above the array.
Abstract: The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays. It combines a surface array to measure secondary particles at ground level together with a fluorescence detector to measure the development of air showers in the atmosphere above the array. The fluorescence detector comprises 24 large telescopes specialized for measuring the nitrogen fluorescence caused by charged particles of cosmic ray air showers. In this paper we describe the components of the fluorescence detector including its optical system, the design of the camera, the electronics, and the systems for relative and absolute calibration. We also discuss the operation and the monitoring of the detector. Finally, we evaluate the detector performance and precision of shower reconstructions.

TL;DR: In this paper, the authors describe the efforts of different Brazilian institutions and research groups on second generation bioethanol production, especially from sugarcane bagasse, and they show that in the coming years, ethanol yield per hectare of cane could reach 10,000 L/ha, if 50% of the produced bagasse would be converted to ethanol.

TL;DR: Progress in developing group A streptococcal vaccines and an increased focus on the lived experience of those with RHD and the need to improve quality of life give cause for optimism that progress will be made against this neglected disease.
Abstract: Despite economic and medical advances, acute rheumatic fever and consequent rheumatic heart disease remain a major public health burden in low and middle-income countries, and a designated priority for the World Health Organisation. The clinical consequences are major and enduring, particularly for women of child-bearing age, and access to diagnosis, preventive therapy and transcatheter or surgical interventions remains a challenge. Herein, we provide a summary of key aspects of the condition, with particular focus on epidemiology, pathogenesis and immune mechanisms, diagnosis and clinical manifestations, contemporary management and preventive strategies.
