Fatal tractor accidents in the agricultural sector in Spain during the past decade
Currently, there is a discrepancy between the number of occupational accidents in the agricultural sector reported by Spanish governmental sources and those actually occurring in general. This is mainly due to the official ... -
Feasibility of using rural waste products to increase the denitrification efficiency in a surface flow constructed wetland
A surface flow constructed wetland (CW) was set in the Lerma gully to decrease nitrate (NO3-) pollution from agricultural runoff water. The water flow rate and NO3 - concentration were monitored at the inlet and the outlet, ... -
Feasibility of vermicomposting of spent coffee grounds and silverskin from coffee industries: a laboratory study
In the coffee industry, several by-products are generated during the production and consumption of coffee and represent an important waste from an environmental viewpoint. For improving the knowledge about this issue, a ... -
Fluid-structure simulation of a general non-contact tonometry. A required complexity?
Understanding corneal biomechanics is important for applications regarding refractive surgery prediction outcomes and the study of pathologies affecting the cornea itself. In this regard, non-contact tonometry (NCT) is ... -
Formulation and solution of curved beams with elastic supports
This article presents the general system of differential equations that governs the behaviour of a curved beam, which can be solved by either numerical or analytical methods. The obtained solution represents the matricial ... -
Frequency domain design of a series structure of robust controllers for multi-input single-output systems
The regulation of a disturbed output can be improved when several manipulated inputs are available. A popular choice in these cases is the series control scheme, characterized by (1) a sequential intervention of loops and ... -
Functionalized electrospun fibers for the design of novel hydrophobic and anticorrosive surfaces
In this work, a novel coating was deposited on aluminum alloy samples by using a combination of electrospinning and chemical vapor deposition (CVD-silanization) techniques in order to create a functionalized film with an ... -
Fútbol e ingeniería: evolución histórica de los terrenos de juego de campos y estadios del fútbol español a través del fútbol navarro
El fútbol ha evolucionado a lo largo de su historia en todos sus aspectos, siendo uno ellos, las superficies de juego y sus alrededores. Pero, ¿qué diferencias hay entre un terreno de juego actual, al de hace 20, 50 o 100 ... -
Gamification and a low-cost laboratory equipment aimed to boost vapor compresion refrigeration learning
The nowadays European educational framework boosts applying the learned theoretical concepts to real situations. Hence, practice sessions are key resources to present students direct applications of the theoretical concepts ... -
Gaseous fueling of an adapted commercial automotive spark-ignition engine: simplified thermodynamic modeling and experimental study running on hydrogen, methane, carbon monoxide and their mixtures
In the present work, methane, carbon monoxide, hydrogen and the binary mixtures 20 % CH4–80 % H2, 80 % CH4–20 % H2, 25 % CO–75 % H2 (by volume) were considered as fuels of a naturally aspirated port-fuel injection four-cylinder ... -
Geomorphological instantaneous unit hydrograph model with distributed rainfall
Two variants of the Instantaneous Unit Hydrograph model based on a Geomorphological association of linear Reservoirs (IUHGR), incorporating the Spatial Variability of Rainfall (SVR), have been developed. The proposed models ... -
A GIS-based methodology for assigning experimental measurements of angular distribution of sky radiance and luminance to selected sky sectors
Mathematical models for the estimation of the angular distribution of diffuse radiance/luminance in the sky describe the anisotropic character of diffuse solar radiation and daylight in the sky vault. In most of these ... -
Grey water footprint as an indicator for diffuse nitrogen pollution: the case of Navarra, Spain
Nitrogen is an essential element for plant growth, while its application and associated pollution is a worldwide concern. Generally, diffuse source pollution and its impacts on ecosystem health are difficult to monitor and ... -
Heat pipes thermal performance for a reversible thermoelectric cooler-heat pump for a nZEB
The nZEB standards reduce the energy demand of these buildings to a minimum, obtaining this little energy from renewable resources. Taking these aspect into consideration, a thermoelectric cooler-heat pump is proposed to ... -
The hemodynamics of aneurysms treated with flow-diverting stents considering both stent and aneurysm/artery geometries
Flow diverting stents are deployed to reduce the blood flow into the aneurysm, which would thereby induce thrombosis in the aneurysm sac; the stents prevent its rupture. The present study aimed to examine and quantify the ... -
Highway paving in the southwestern Amazon alters long-term trends and drivers of regional vegetation dynamics
Infrastructure development, specifically road paving, contributes socio-economic benefits to society worldwide. However, detrimental environmental effects of road paving have been documented, most notably increased ... -
Holographic acoustic tweezers
Acoustic tweezers use sound radiation forces to manipulate matter without contact. They provide unique characteristics compared with the more established optical tweezers, such as higher trapping forces per unit input power ... -
Humidity sensor based on silver nanopartlcles embedded in a polymeric coating
In this work, it is presented a novel optical fiber humidity sensor based on silver nanoparticle-loaded polymeric coatings built onto an optical fiber core. The polymeric film was fabricated using the Layer-by-Layer assembly ... -
Hydrophobic and corrosion behavior of sol-gel hybrid coatings based on the combination of TiO2 NPs and fluorinated chains for aluminum alloys protection
In this work, layers of a sol-gel hybrid matrix doped with metal oxide nanoparticles (TiO2 NPs) have been deposited on flat samples of AA6061-T6 aluminum alloy using the dip-coating technique, with the aim of obtaining ... -
Hyperspectral imaging to assess the presence of powdery mildew (Erysiphe necator) in cv. Carignan Noir grapevine bunches
Powdery mildew is a worldwide major fungal disease for grapevine, which adversely affects both crop yield and produce quality. Disease identification is based on visible signs of a pathogen once the plant has already been ...
