that live, grow, reproduce, and interact within ecosystems help to mediate local and regional flows of energy and materials (Figure 4). Energy flow refers to the capture of light energy by green plant or algal photosynthesis and its dispersal as chemical energy throughout the food web to plant- or algal-feeding animals, predators, and eventually decomposers. The flow of materials involves the recycling of carbon, nitrogen, phosphorus and other elements between living organisms and the air, water

The Identification of damage in Large Structures By Alan P. Jeary D.Sc., Ph.D., CEng., FIStructE, FAIB, FRMetS, MAIBS, MIEE. University of Western Sydney, Australia. Introduction It is necessary, when considering the identification of damage in large structures, to be very precise about both what constitutes damage, and of the precise requirements for successful identification. These considerations are not trivial, our classical identification of damage is often unhelpful in an…

feldspars composition, quartz and rock fragments types allows to establish the complex history of the sediments from their source areas to the depositional sites. Furthermore, modern microanalytical techniques allow the precise determination of the chemical composition of individual grains through electron microprobe (e.g. garnets and tourmalines), the ages of zircon, monazite and titanite through SHRIMP (Sensitive High Resolution Ion Microprobe) or ICPMS – LA (Inductively-Coupled Plasma…

Towards the Andes the shingle gives place to porphyry, granite, and basalt lavas, animal life becomes more abundant and vegetation more luxuriant, acquiring the characteristics of the flora of the western coast, and consisting principally of southern beech and conifers. The high rainfall against the western Andes (Wet Andes) and the low sea surface temperatures offshore give rise to cold and humid air masses, contributing to the ice-fields and glaciers, the largest ice-fields in the…

atual. MWCNTs administrados pela traquéia a ratos mostraram inflamação e fibrose. Estes permaneceram nos pulmões após 60 dias na menor dose administrada. Após dois meses foram caracterizados granulomas ricos em colágeno. Análises pelo teste de Western blot mostraram que SWCNTs podem induzir baixa na expressão de proteínas associadas com adesão como laminina, fibronectina, caderina. Estes resultados sugerem que SWCNTs podem contribuir para a apoptose de células. O comportamento de…

caracterização da biomassa in-natura no Laboratório de Processos Térmicos e Engenharia Ambiental (Protea) da FEM da Unicamp, enquanto que aproximadamente 10 quilos da matéria-prima foram enviados ao Institute for Chemicals and Fuels from Altenative Resources (ICFAR), pertencente a University of Western Ontario (UWO), no Canadá, para a realização experimentos em uma planta piloto de pirólise rápida com um sistema para a conversão de biomassa sólida na ausência de oxigênio. Nas análises…
