We propose a system for measuring entropy variations, S, in thermal systems using pyroelectric sensors. These sensors convert time-dependent temperature variations into electrical current. Consequently, heat and ...

he beam-to-column connections in most of the pallet rack structures made of thin-walled steel sections are of the clip-on type. These connections are of a semi-rigid nature and have a non-linear moment–rotation relationship, ...

‘Calçots’, the immature floral stems of second-year onion resprouts, are an economically important traditional crop in Catalonia (Spain). Classical approaches to evaluating the chemical properties of ‘calçots’ are time ...

Càlcul d'assentaments en sòl orgànic per la construcció d'una piscifactoria

In the last two years, Europe has experienced a rise in skin allery and dermatitis due to goods and Asian provenance that have been treacted with dimethylfumarate (DMFU). Accordingly,laboratories in the leather and foodwear ...

Taking into account that the age of structures is closely connected to their energy consumption, the monitoring of structures is a crucial task for engineers. This article deals with application of Arduino based low-cost ...

[ANGLÈS] In the last centuries new technologies and structural knowledge have made possible the construction of filigree structures, which economize the required material quantities by taking material capacity to its limits. ...
