Olive Mill Wastewater (OMWW) treatment is considered to be one of the main challenges that Mediterranean countries face. Although several procedures and technologies are mentioned in the literature, these techniques have several disadvantages or have been limited to laboratory pilot validation without posterior industrial projection. Recently, an advanced environmental friendly strategy for the...

In the present study, the application of a BP neural network for prediction of the moisture content of barberry fruit (berberis vulgaris) during drying was investigated. The important parameters namely, pretreatment (heat shocking, olive oil + K2CO3 and NAT), air drying temperature (60, 70 and 80oC), air drying velocity (0.3, 0.5 and 1 m/s) and time (s) were considered as the input parameters a...

Rice drying with infrared radiation has been investigated during recent years and showed promising potential with improved quality and energy efficiency. However, due to limited penetration capability of infrared radiation, thin layer drying may be used in infrared dryer design. The objective of this study was to study the moisture removal characteristics of thin layer rough rice heated by infr...

We study a theoretical model of mud cracks, that is, the fracture patterns resulting from the contraction with drying in a thin layer of a mixture of granules and water. In this model, we consider the slip on the bottom of this layer and the relaxation of the elastic field that represents deformation of the layer. Analysis of the one-dimensional model gives results for the crack size that are c...

Coatings with vertical gradients in composition were produced by drying an aqueous polymer dispersion containing both charged and neutral particles. After drying, the neutral component was enriched at the film/air interface. The spontaneous vertical segregation between the two types of particles goes back to a difference in collective diffusivity. As the film dries, a layer enriched in polymer ...

the present study investigated the influence of air temperature and velocity on the drying kinetics and specific energy consumption during fluidized bed drying of soybean at 80, 100, 120 and 140ºc and airflow rates of 1.8, 3.1 and 4.5 m s-1. six mathematical models for describing the fluidized bed drying behavior were investigated. the value of the drying rate coefficient (k) increased with inc...

The damage evolution of concrete subjected to drying-wetting cycles in different concentration of sodium sulfate solution was investigated based on micro and macro-observations. Through the experiment, weight loss, compressive strength loss and the damage layer thickness of concrete were measured after different drying-wetting cycles. The mechanical properties degradation in the damage layer of...

Organic electronic devices are often made by solution processing a multi-component ink. During solution processing, e.g. via spin coating, the solvent evaporates and the solid components deposit on the substrate. The morphology of this layer can range from wellmixed to extensively phase separated. To optimize device performance, it is essential to 2 control the degree and dominant length scale ...

Transplantation brings hope for many patients. A multidisciplinary approach on this field aims at creating biologically functional tissues to be used as implants and prostheses. The freeze-drying process allows the fundamental properties of these materials to be preserved, making future manipulation and storage easier. Optimizing a freeze-drying cycle is of great importance since it aims at red...

In this study the correlation between lag factor G and Page ́s mathematical model parameter n was developed. Using the newly developed correlation the presence of internal or external resistance to moisture transfer during thermal drying can be verified. As modeling tools Artificial neural networks (ANN) and Adaptive neuro-fuzzy inference system (ANFIS) were used. The best model for determinatio...
