This article aims to analyze the problems and possible solutions to the implementation of a basic sanitation infrastructure, especially the solid waste collection in poor class occupations in the city of São Paulo, Brazil. The manner in which the urban accesses are structured in the Favela of Heliopolis, with dimensions and configuration insufficient, do not allow access to motorized vehicles, lea

Popular Abstract in Swedish Cancer är ett samlingsnamn på sjukdomar som kännetecknas av okontrollerad celltillväxt. I friskt tillstånd växer kroppens celler kontrollerat. Cancertillståndet startar när någon av dessa celler förändras så att tillväxten ökar. När tillväxten ökar så tilltar också celldelningen. Om ingen åtgärd vidtas kommer cancern till slut att slå ut funktionen hos det organ som denCancer is the collective name for diseases that have one thing in common ? uncontrolled cell growth. The increase in cancer cell proliferation eventually results in tumor formation and, in the worst case, metastatic spread to other organs. Common treatment modalities of cancer include chemotherapy and radiation therapy. However, these methods are associated with severe side effects as well as indu

The increasing test data volume needed for the testing of System-on-Chips (SOCs) leads to high Automatic Test Equipment (ATE) memory requirement and long test application times. Scheduling techniques where testing can be terminated as soon as a fault appears (abort-on-fail) as well as efficient compression schemes to reduce the ATE memory requirement have been proposed separately. Previous test da

It is claimed that risk communication has the epistemic goal to inform and the pragmatic goal to change the recipients’ behaviour. The recipients should be considered as active agents with robust knowledge. Technical as well as psychological tools may be used to change the current knowledge state of the recipient and thereby her behaviour. These tools are mutually dependent and will change both th

Today, it is often said that we stand at the opening of a postindustrial “knowledge society,” where private enterprise has become increasingly dependent on research and innovation and where education has become a prerequisite for success on the labor market. This idea serves as a source of inspiration when governments, corporations and institutions elaborate policies and strategies for future deve

Popular Abstract in Swedish Kroppens rörelser åstadkommes genom sammandragning av muskelvävnad som kan vara av två slag, glatt eller tvärstrimmig. Den senare sorten kan indelas i skelett och hjärtmuskulatur, vilka har mycket olika egenskaper trots den gemensamma benämningen. Muskelvävnaden är uppbyggd av långsträckta, spolformade celler som innehåller tunna och tjocka kontraktila filament, beståenThe initial signal for contraction in smooth muscle is an increase in [Ca2+]i. Ca2+ ions can either enter the cytosol from the extracellular medium or be released from intracellular stores. Voltage-operated Ca2+ channels (VOC) play a dominant role in the activation of smooth muscle contraction. This thesis describes two novel regulatory mechanisms of the dihydropyridine (DHP)-sensitive VOC in smoo

Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface of arbitrary material, ie the radome, is analyzed. The transformation is based on a vector surface integral representation that relates the
