We have recently realised that intermediate polars accrete in a range of modes. While accretion is predominantly through an accretion disc, in some systems the accretion stream overrows the disc and interacts with the magnetic eld directly. In RX 1712{24, discless accretion dominates. I review the current status of these observations, concentrating on the information from the X-ray lightcurves.

Intermediate polars range from systems which accrete entirely via discs (e.g. EX Hya) through systems which combine disc and disc-overrow accretion (e.g. FO Aqr) to discless accretors (e.g. RX 1712{ 24). The accretion curtain model provides a good description of the optical spin-pulses, while in the X-ray regime, occultation combines with absorption to create complex pulse-prooles.

The links among environmental change, notions of security, and social conflicts in the Brazilian Amazon are multiple and complex. Successive Brazilian governments and the Brazilian military have found a distinct relationship between environmental matters and security issues through a focus on state sovereignty. This relationship is often articulated in terms of defending national sovereignty in...

The objective of this article is to present an overview the changes in Brazilian science fiction throughout past decades, which culminated international and national success film Bacurau emergence new subgenres amazofuturismo sertãopunk continuation Causo’s tupinipunk. These are bringing plate topics such as nationalism, decolonization, racism, social justice, globalization, while using pop for...

The present study examines the process of globalization popular Brazilian Portuguese (PBP) through spreading capoeira outside Brazil. Based on ethnographic fieldwork in New York City and eight years practice, my objective is to demonstrate that PBP variety exported abroad by practitioners, non-Brazilian ones are learning this non-standard as essential their identity a community practice. Conseq...

The emergence of Extended-Spectrum Beta-Lactamase (ESBL)-producing microorganisms in Brazilian hospitals is a challenge that concerns scientists, clinicians and healthcare institutions due to the serious risk they pose to confined patients. The goal of this study was the detection of ESBL production by clinical strains of Escherichia coli and Klebsiella sp. isolated from pus, urine and blood of...

a woman presenting with severe right lower quadrant (rlq) abdominal pain is presented here. she was evaluated for all usual cause of such pain. laboratory tests and abdominal and pelvic sonography was normal. mri revealed l1-l2 disc herniation.

Materials and methods The League of Diabetes adopted screening for diabetic foot, recommended by the Brazilian Society of Diabetes and BrasPEDI-Brazilian Group of Diabetic Foot, through the achievement of a score of neuropathic symptoms and signs (sensitivities tactile, painful, vibration, thermal and Achilles reflex), and clinical evaluation of arteriopathy. The work was carried out by members...
