Abstract
The invention refers to a method of producing a cement paste construction material (4) by mixing a cement (3), an aqueous sericin solution (1) in a first mixing zone (2). Subsequently, the cement paste construction material (4) is mixed with a fine-grain bulk material mixture (6) in a second mixing zone (5) to obtain a mortar construction material (7). Subsequently, the mortar construction material (7) is mixed with a coarse-grain bulk material mixture (9) in a third mixing zone (8) to obtain a concrete construction material (10). Admixtures (11) may be feed to each mixing stage. The present invention also contributes to saving water in the concrete production, substituting it by a silk degummed wastewater as a hydration agent. The compositions according to the invention present increased mechanical properties, namely compressive strength, prevent mold growth or proliferation of fungi or other microorganisms, and are durable and stable under thermal oscillations.

Abstract
A method and device to monitor the anesthetic state of animal patients undergoing general anesthesia are provided. Electroencephalogram derived parameters are commonly used tools for anesthetic depth monitoring in human patients. However, there are no objective measures of anesthetic depth monitoring available for veterinary use. Furthermore, the parameters available for humans have showed inadequacy in animals. A robust invention which is adaptable to the species anesthetized and to the anesthetic drugs used is presented. This invention transforms (5, 6, 7, 8) the animal's EEG (4) into an easy to interpret parameter (10) that reflects the anesthetic depth. This parameter undergoes continuous optimization according to the anesthesiologists' input (9) regarding the animal anesthetic state, species and anesthetic protocol. This function performs fine tuning resulting in a parameter which correlates with anesthetic state, optimized for each species and anesthetic protocol, helping the anesthesiologist to adjust the drug doses and to automatically control the administration of anesthesia.

Abstract
The present invention refers to a non-destructive method for vigor and vegetative expression determination in tree- shrub vegetation, which is oriented along surfaces (e.g. grapevines and actinideae), regardless of their variety group. The method consists of acquiring an on-field digital image of the grapevine (1), which is subject to digital processing (2), giving way for the identification, localization and isolation of the reference mark (5), which will allow determining the area of a pixel, and the grapevine canes (6), in order to calculate the total area of the canes. Based on a pixel area in the total area of the canes, on the cane quantity and on the medium area per cane and medium weight per cane polynomial ratio (3), the vigor and vegetative expression (4) are thus obtained. The application field of this method may be, for example, the Wine-growing sector.

Abstract
This invention refers to an agglomeration process of wood fibres which consists of an impregnation and/or pulverisation of fibres with a pre-polymer of hydroxyl terminated polybutadiene (HTPB), a di-isocyanate and possibly a catalyst to obtain slabs of fibre agglomerations (fibreboards). Theagglomerating system used in the process is formaldehyde-free. It is therefore an alternative to the current processes that use formaldehyde-based agglomerates and also fulfils the most demanding environmental criteria. Thisprocess aims to produce agglomerated fibreboard slabs in different densities such as medium density fibreboard (MDF) and high density fibreboard (HDF) which have better physical and mechanical properties resulting therefore in a better quality product and therefore also enabling exemplary quality slabs to be obtained irrespective of the nature of the wood fibreboard whether it is hardwood or resin-based.

Abstract
This invention relates to a particle agglomeration process of wood and cork which uses an agglomerating system consisting of a pre-polymer of hydroxyl terminated polybutadiene (HTPB), a di-isocyanate and possibly a catalyst in order to obtain agglomerations of cork and/or wood particles with new characteristics and with new particle compositions. These products are used in the particle agglomeration industry in the wood sector (wood particles boards), specifically in the panels and veneers sub-sector and in the cork agglomeration industry sub-sector. This process enables the industrial reprocessing of residues and sub-products of sectors of wood and cork and at the same plays its part towards solving environmental problems by creating a viable and profitable alternative to storage and/or burning and/or depositing in the ground, in particular for what is referred to as cork powder and 'terras' and some wood residues, in particular fibre and polishing dust.
