3. Comparing the Performance of Ground Filtering Algorithms for Terrain Modeling in a Forest Environment Using Airborne LiDAR Data
ABSTRACT The aim of this study was to evaluate the performance of four ground filtering algorithms to generate digital terrain models (DTMs) from airborne light detection and ranging (LiDAR) data. The study area is a forest environment located in Washington state, USA with distinct classes of land use and land cover (e.g., shrubland, grassland, bare soil, an

4. Cues to the usefulness of grooming behavior in the evaluation of anxiety in the elevated plus-maze
Grooming behavior has been reported to be a response to novelty and other stressors. However, studies that sought to identify anxiety-related measures in the elevated plus-maze have not found grooming as a reliable index. Grooming has been implied with dearousal after a stressful experience. In the present work, a detailed investigation of this behavior was

5. Processo de decomposição e padrão sucessional de artrópodes em carcaças de suínos expostas em locais abrigados e desabrigados / The process decomposition and the successional pattern of arthropods in pig carcasses exposed to unsheltered environments
Forensic Entomology uses data, mainly from carrion insects, to estimate the Post Mortem Interval (PMI). The oviposition pattern of these insects can be influenced by several factors, such as the presence of materials in the vicinity of the body, whether the corpses are buried, burned or disposed in open or closed environments, etc. These factors can affect t

6. Percepção dos stakeholders da Embraco, à luz das dimensões da responsabilidade social corporativa
Corporate social responsibility (CSR) is a relatively recent issue in Brazil, compared with other countries. Its understanding and application have generated discussion in academic and business environments, due to the multitude of other terms that are sometimes confused and sometimes complement each other, in order to explain and minimize the impacts of the

7. Diversidade de Scarabaeinae (ColeÃptera: Scarabaeidae) na Caatinga do Parque Nacional do Catimbau, BuÃque - PE
This study aimed to ascertain the Scarabaeinae fauna from Parque Nacional do Catimbau, BuÃque - PE, and assess the response of their communities, in open and closed environments, to the variation pluviometric. The Scarabaeinae (Coleoptera: Scarabaeidae) are considered useful as biological indicators and have been used to investigate the effects of disturban

8. Os efeitos do tempo de exposição do sujeito às atividades sem reforço programado sobre a efetividade do desempenho em esquema temporal de reforçamento / The effect of exposure to activities without programmed reinforcers on performance effectiveness under temporal schedule of reinforcement
O presente estudo pretendeu investigar os efeitos do tempo de exposição dos sujeitos às atividades sem reforço programado sobre a efetividade do desempenho submetido a um esquema temporal de reforçamento. Duas outras perguntas nortearam o trabalho: (a) ocorreria alguma mudança nos padrões das atividades sem reforço programado em função do tempo de

9. Alloying in GeSi:Si (001) epitaxial nanocrystals / Formação de ligas em nanocristais epitaxiais de GeSi:Si (001)
The structural and electronic properties of nanoscale materials strongly depend on the chemical composition, as well as their size and shape. A big variety of morphologies can be achieved by controlling the experimental conditions during the epitaxial growth of Ge on a Si(001) substrate. In particular, three-dimensional islands with well defined size and sha

10. Petrogenese das intrusões graniticas compostas de Teofilandia e Barrocas, Greenstone Belt do Rio Itapicuru, Bahia, Brasil
The Rio Itapicuru Greenstone Belt (RIGB) is a Paleoproteozoic sequence situated in the northern portion of the São Francisco Craton, Bahia state, Brazil. Overlying a basement consisting of gnaisse and migmatites, this volcanic-sedimentary belt is intruded by several granitoid intrusions of different chemical compositions. Two of the most important intrusive

11. Contrasting effects of alpha and beta globin regulatory elements on chromatin structure may be related to their different chromosomal environments.
Expression of the human alpha and beta globin gene clusters is regulated by remote sequences, referred to as HS -40 and the beta-locus control region (beta-LCR) that lie 5-40 kb upstream of the genes they activate. Because of their common ancestry, similar organization and coordinate expression it has often been assumed that regulation of the globin gene clu

12. Elevated Plus Maze for Mice
Although the mouse genome is now completely sequenced, the functions of most of the genes expressed in the brain are not known. The influence of a given gene on a specific behavior can be determined by behavioral analysis of mutant mice. If a target gene is expressed in the brain, behavioral phenotype of the mutant mice could elucidate the genetic mechanism
