1. Optimal Simulation of the Land-Use Structure Based on the Local Ecological Environment: the Case of Huanghua City in Hebei Province, China
ABSTRACT The overuse of land has resulted in a sharp decline in ecological functions, affecting the environment as it relates to the existence and sustainable development of the whole biosphere. This work aims to evaluate the ecological and economic efficiencies of the land-use structure. A simulation model, CLUE-S (Conversion of Land-Use and its Effects at

2. Current and future land use and land cover scenarios in the Arroio Marrecas watershed
RESUMO Este estudo avaliou as mudanças históricas do uso do solo e da cobertura da terra na bacia hidrográfica de Arroio Marrecas (Caxias do Sul, RS) e simularam futuros cenários de uso do solo até 2034. As simulações espaciais e temporais foram conduzidas com o modelo CLUE-S (“Conversão de Uso da Terra e seus Efeitos-Pequena Extensão Regional”)

3. Estimativa da produção de sedimentos em função da mudança de uso e cobertura do solo
Os processos de mudança de uso e cobertura do solo despertam grande preocupação quanto a se compreender e melhor planejá-los a fim de evitar impactos, como perda da biodiversidade, erosão do solo e contaminação dos recursos hídricos. O trabalho propõe estimar a produção de sedimentos em cenários da microbacia hidrográfica do ribeirão das Guabir

4. RANKING OF WEB PAGES BY LEARNING MULTIPLE LATENT CATEGORIES / CLASSIFICAÇÃO DE PÁGINAS WEB POR APRENDIZAGEM DE MÚLTIPLAS CATEGORIAS LATENTES
The rapid growth and generalized accessibility of the World Wide Web (WWW) have led to an increase in research in the field of the information retrieval for Web pages. The WWW is an immense and prodigious environment in which Web pages resemble a huge community of elements. These elements are connected via hyperlinks on the basis of similarity between the co

5. Estimativa do escorrimento superficial e da produção de sedimentos em áreas de atividades agrossilvopastoris, no Estado de São Paulo, em função da mudança de uso e cobertura do solo / Runoff and sediment yield estimation in agroforestry areas in São Paulo state due to changes in land use and land cover
O significativo investimento em desenvolvimento tecnológico associado aos fatores ambientais, como disponibilidade de recursos naturais, clima e solo elevaram o Brasil ao patamar de maior produtor mundial de cana-de-açúcar, matéria-prima do açúcar e do etanol. Atualmente, o país exporta açúcar para mais de 100 países. Em relação ao etanol, esse v

8. Inhibitory effect of a visual prime stimulus in simple reaction time task. / Efeito inibidor de um estímulo precedente visual em uma tarefa de tempo de reação simples.
Studies about attention orienting that use Posner?s procedure have demonstrated two effects: an initial facilitation of responsivit when the target stimulus appears in the same location as the prime stimulus and a subsequent inhibition of this responsvity. In a previous work we could not find the early facilitatory effect of attention orienting in a simple r

9. Does the correlation between EBNA-1 and p63 expression in breast carcinomas provide a clue to tumorigenesis in Epstein-Barr virus-related breast malignancies?
Several investigators have identified Epstein-Barr virus (EBV) particles in breast carcinomas, a fact that supports a role for EBV in mammary tumorigenesis. The possible mechanism involved in this process is not clear. The present study was carried out in an attempt to determine whether there is a relationship between latent infection with EBV and p53 and p6

10. Interruption of the blood-stage cycle of the malaria parasite, Plasmodium chabaudi, by protein tyrosine kinase inhibitors
Malaria is a devastating disease caused by a unicellular protozoan, Plasmodium, which affects 3.7 million people every year. Resistance of the parasite to classical treatments such as chloroquine requires the development of new drugs. To gain insight into the mechanisms that control Plasmodium cell cycle, we have examined the effects of kinase inhibitors on

11. Adrenocortical tumors in children
Childhood adrenocortical tumors (ACT) are rare. In the USA, only about 25 new cases occur each year. In Southern Brazil, however, approximately 10 times that many cases are diagnosed each year. Most cases occur in the contiguous states of São Paulo and Paraná. The cause of this higher rate has not been identified. Familial genetic predisposition to cancer
