Neste estudo, avaliou-se a fração hidrofóbica de Ca, Fe, Mg e Zn em méis escuros por meio de extração em fase sólida utilizando material à base de sílica gel com grupos ativos fenil ligados monomericamente. Verificou-se que Fe está associado com esta fração, provavelmente compostos polifenólicos, no mais alto grau. A contribuição da fração hidrofóbica no conteúdo total deste elemento nos méis a...

Greening of facades is a non-expensive option to increase the amount of vegetation in urban areas. Especially in areas with dense settlement, the filtering effect of facade greening can improve urban air quality. In this paper, results from field experiments and numerical simulations are presented. Using Atomic Absorption Spectrometry the amount of heavy metals on leaf samples from seven houses...

An Improved Synthetic Variable Ratio (ISVR) fusion method is proposed to merge high spatial resolution panchromatic (Pan) images and multispectral (MS) images based on a simulation of the panchromatic image from the multispectral bands. Compared to the existing SVR (Synthetic Variable Ratio) family methods, the ISVR method manifests two major improvements: a simplified and physically meaningful...

A vital issue in context of modern distributed com puting environments is a simple and safe use of the computing storage and communication facilities present on the network In this paper we propose an agent based architectural concept for such an envi ronment which should assist the user in submitting requests to the distributed system in a transparent way The user should not need speci c knowl...

This paper presents a new approach to generate the workspace of planar redundant manipulators based on the workspace density of a single link. The workspace density of planar serial redundant manipulators can be computed efficiently by using the concept of the Fourier transform for the group of rigid-body motions of the plane and the convolution theorem. For manipulators using discrete actuatio...

Surface light fields can be used to render the complex reflectance properties of a physical object. One limitation is that they can only represent the fixed lighting conditions of the environment where the model was captured. If a specific lighting condition is desired, then there are two options: either use a combination of physical lights as an approximation, or capture a full 6D surface refl...

We investigated the determination of N-methylcarbamate pesticides and their metabolites in agricultural products by HPLC with post-column fluorescence detection after clean-up with an SPE cartridge. The homogenate of agricultural products was extracted with acetone. The crude extract was partitioned between 5% sodium chloride solution and dichloromethane, and the dichloromethane layer was conce...

A well-designed build up environment should include thermally comfortable outdoor spaces as well low energy and buildings, this paper aims to evaluate a coupling method between ENVI-met 4 microclimate model IESVE Building Energy Modelling (BEM) software. The calculation for the conditions is used specify thermal boundary building simulation modelling give realistic consumption profile. results ...

Within the scope of study, thermal comfort analysis was performed using ENVI-met program Misak-ı Milli Square in Safranbolu, and it determined that perception square as slighty warm-warm. For this reason, a new design proposal has been submitted for square. In proposal, green ratio number trees increased, type location changed. The flooring materials replaced with stone covering higher albedo f...
