1. NONLINEAR MIXED-EFFECT HEIGHT-DIAMETER MODEL FOR Pinus pinaster AIT. AND Pinus radiata D. DON
ABSTRACT Tree height-diameter (H-D) relationships are important for routine forest assessment. Several H-D relationships have been developed for different species and more are still evolving. This study introduces new H-D model developed for Pinus pinaster and Pinus radiata in Spain, based on data from 184 and 96 permanent sample plots, respectively, collect

2. Prediction of restrained shrinkage crack width of slag mortar composites using data mining techniques
ABSTRACT The purpose of this study is to develop data mining models to predict restrained shrinkage crack widths of slag mortar cementitious composites. A database published by BILIR et al. [1] was used to develop these models. As a modelling tool R environment was used to apply these data mining (DM) techniques. Several algorithms were tested and analyzed u

3. Water loss in table grapes: model development and validation under dynamic storage conditions
Abstract Water loss is a critical problem affecting the quality of table grapes. Temperature and relative humidity (RH) are essential in this process. Although mathematical modelling can be applied to measure constant temperature and RH impacts, it is proved that variations in storage conditions are normally encountered in the cold chain. This study proposed

4. Anopheles fauna of coastal Cayenne, French Guiana: modelling and mapping of species presence using remotely sensed land cover data
Little is known about the Anopheles species of the coastal areas of French Guiana, or their spatiotemporal distribution or environmental determinants. The present study aimed to (1) document the distribution of Anopheles fauna in the coastal area around Cayenne, and (2) investigate the use of remotely sensed land cover data as proxies of Anopheles presence.

5. A Forecasting Tool for Predicting Australia's Domestic Airline Passenger Demand Using a Genetic Algorithm
ABSTRACT: This study has proposed and empirically tested for the first time genetic algorithm optimization models for modelling Australia's domestic airline passenger demand, as measured by enplaned passengers (GAPAXDE model) and revenue passenger kilometres performed (GARPKSDE model). Data was divided into training and testing datasets; 74 training datasets

6. Distribuição geográfica de abelhas e plantas associadas através de modelagem computacional / Geographical distribuition of associated bees and plants through computational modeling
As abelhas e plantas apresentam diferentes graus de especialização em suas interações. Parceiros mais especialistas frequentemente apresentam uma história evolutiva mútua e sobreposição nas áreas de ocorrência. No entanto, a estrutura espacial dos ambientes nos quais esses grupos se distribuem é caracterizada por padrões complexos e dinâmicos. P

7. Modelagem molecular de uma série de compostos inibidores da enzima integrase do vírus HIV-1 / Molecular modelling for a series of integrase HIV-I inhibitors
An essential step in the HIV life cycle is integration of the viral DNA into the host chromosome. This step is catalyzed by a 32-kDa viral enzyme HIV integrase (IN). HIV-1 IN is an important and validated target, and the drugs that selectively inhibit this enzyme, when used in combination with reverse transcriptase (RT) and protease (PR) inhibitors, are beli

8. Avaliação das ferramentas de modelagem preditiva de nicho fundamental para espécies de aves do Parque Estadual da Serra do Mar e Núcleo São Sebastião - SP / Evaluation of predictive modelling tools of fundamental niche for species of birds in the Parque Estadual da Serra do Mar e Núcleo São Sebastião
Os modelos de distribuição de espécies (MDEs) utilizam dados de ocorrência de campo e variáveis ambientais para indicar locais adequados para a ocorrência de uma espécie. Apesar dos inúmeros trabalhos que avaliam diversos aspectos deste tipo de modelagem, a aplicação desses métodos para predição do distribuição potencial de espécies de aves e

In this work, experimental data of the liquid-liquid equilibrium for the aqueous twophase systems water + PEG8000 + magnesium sulfate and water + PEG8000 + sodium sulfate were determined at 25 e 50°C. The compositions of both equilibrium phases were obtained by a gravimetric method, using the lyofilization (freeze-drying) technique for the water determinati

12. Eutrophication of Cruzeta reservoir in the representative basin of the Seridó river - RN. Natal / Eutrofização do Reservatório Cruzeta na bacia representativa do rio Seridó RN
Eutrophication has been listed as one of the main problems of water pollution on a global level. In the Brazilian semi-arid areas this problem takes even greater proportions due to characteristical water scarcity of the region. It is extremely important to the predictive eutrophication models development and to the reservoirs management in the semi-arid regi
