13. Where is sugarcane cropping expanding in the brazilian cerrado, and why? A case study
ABSTRACT Sugarcane growing area in Brazil sharply expanded between 2000 and 2010 due to the increasing world demand for sugar and ethanol. Since this expansion of sugarcane is said to occur in areas covered by degraded pastures, it is likely not threatening the environment or food production. In order to verify this assumption, we investigate at farm and fie

14. A New Fifth-Order Shear and Normal Deformation Theory for Static Bending and Elastic Buckling of P-FGM Beams
Abstract A new fifth-order shear and normal deformation theory (FOSNDT) is developed for the static bending and elastic buckling analysis of functionally graded beams. The properties of functionally graded material are assumed to vary through the thickness direction according to power-law distribution (P-FGM). The most important feature of the present theory

15. Challenges and developments in research of the early stages of bipolar disorder
Recently, attention in the field of bipolar disorder (BD) has focused on prevention, including early detection and intervention, as these strategies have the potential to delay, lessen the severity, or even prevent full-blown episodes of BD. Although knowledge of the neurobiology of BD has advanced substantially in the last two decades, most research was con

16. Yoga for asthma
ABSTRACT BACKGROUND: Asthma is a common chronic inflammatory disorder affecting about 300 million people worldwide. As a holistic therapy, yoga has the potential to relieve both the physical and psychological suffering of people with asthma, and its popularity has expanded globally. A number of clinical trials have been carried out to evaluate the effects

17. Effect of copper carbonate and zinc oxide applied to seeds on copper and zinc uptake by maize seedlings
ABSTRACT Seed treatment is an interesting alternative to deliver micronutrients to field crops. The aim of this study was to investigate the uptake of Cu and Zn by maize seedlings, with the application of the water-insoluble sources copper carbonate and zinc oxide as seed treatment. Treatments were composed of a control (untreated seeds), five doses of coppe

18. Favorable conditions for Xanthomonas axonopodis infection in Eucalyptus spp.
Currently, Xanthomonas axonopodis is one of the main foliar pathogens for Eucalyptus spp. in Brazil. It induces leaf blight and defoliation of seedlings in the nursery and young plants in the field. However, little is known about thefavorable conditions for infection. The establishment and development of bacterial leaf blight caused by X. axonopodis in eucal

19. Ethnopharmacology: quo vadis? Challenges for the future
It is well-known that humans have used medicinal plants for millennia, but as a defined field of scientific research called ethnopharmacology, it has a relatively short history. It is linked to the development of pharmacology in the 19th century (as exemplified in the work of Claude Bernard linking the explorers' observations on traditional uses of medicines

20. Human molecular cytogenetics: from cells to nucleotides
The field of cytogenetics has focused on studying the number, structure, function and origin of chromosomal abnormalities and the evolution of chromosomes. The development of fluorescent molecules that either directly or via an intermediate molecule bind to DNA has led to the development of fluorescent in situ hybridization (FISH), a technology linking cytog

22. Litterfall dynamics in a iron-rich rock outcrop complex in the southeastern portion of the Iron Quadrangle of Brazil
Ecosystems on cangas (duricrust) present considerable heterogeneity of habitats due to microtopographic variations, soil accumulation and a variety of plant functional groups. Therefore, spatial and temporal ecosystem processes such as litterfall are to be expected to be large, and the absence of a level of productivity represents all the facets of iron-rich

23. Dentro do nevoeiro: diálogos cruzados entre arte e arquitetura contemporânea / Inside the mist: crossed dialogues between contemporary art and architecture
No \"campo ampliado\" da cultura contemporânea, arte e arquitetura partilham cada vez mais questões comuns. Assim, seja em relações de colaboração, ou seja em relações de afrontamento, a arquitetura e a arte hoje dissolvem suas antigas fronteiras disciplinares para compor um poderoso complexo social e midiático, cujo sentido é fundamental para a co

24. Raciocínio pictórico: campos de cor no espaço
The object of this dissertation research involves the design, construction and theoretical analysis of color fields in a three dimensional space, developed through a pictorial reasoning. The starting point for the creation of these work pieces is the appropriation of common objects of everyday use. To address this, I will use Arthur Dantos concept of transfi
