(1) Background: In agro-ecosystems, the success of the crops has a strong connection to biodiversity in the landscape. In the face of climate change, it is important to understand the response to environmental variation of weed species by means of their distribution. In the last century, biodiversity has been impacted due to a variety of stresses related to climate change. Although the composition of vegetation tends to change at a slower rate than climate change, we hypothesize species present in weed communities are distributed in diverse patterns as a response to the climate. Therefore, the

Pseudomonas viridiflava was originally reported as a bean pathogen, and subsequently as a wide-host range pathogen affecting numerous plants species. In addition, several authors have reported the epiphytic presence of this bacterium in “non-host plants”, which may act as reservoir of P. viridiflava and source of inoculum for crops. A new biotype of this bacterium, showing an atypical LOPAT profile, was found in Asturias, a Northern region of Spain, causing significant damage in beans, kiwifruit, lettuce, and Hebe. In order to investigate the involvement of weeds in bean disease, samples were

Spain is the second highest rice-producing country in the European Union, with approximately 105,000 ha used to grow this crop. The major rice-producing regions in Spain are Andalusia, Extremadura, Catalonia, and Valencia, followed by Aragon and Navarre. The main soil texture throughout Spanish rice areas is silty clay loam, with alkaline soils (pH > 7.5)—except in the Extremadura area (pH = 5.5–6)—and a low organic matter content. Water quality in terms of salinity is acceptable, although in some coastal rice areas salinity issues occasionally appear to be a determining factor for high yie

Faba bean is an important legume crop worldwide, which is grown both for food and feed. As for many legume crops, postemergence weed control is difficult. The aim of this work was to assess the potential of intercropping in weed management by assessing the effect of mixing faba bean with different crops (wheat, barley, and pea) on weeds in the South of Spain. Four field trials were conducted over four consecutive seasons, and the results found that the addition of alternate intercropping of faba bean and barley achieved high levels of weed control, both for coverage and biomass (92.7% and 76.6

In the context of detection of weeds in crops for site-specific weed control, on-ground spectral reflectance measurements are the first step to determine the potential of remote spectral data to classify weeds and crops. Field studies were conducted for four years at different locations in Spain. We aimed to distinguish cruciferous weeds in wheat and broad bean crops, using hyperspectral and multispectral readings in the visible and near-infrared spectrum. To identify differences in reflectance between cruciferous weeds, we applied three classification methods: stepwise discriminant (STEPDISC)

Herbicide-resistant weeds currently challenge sustainable food production in almost all cropping systems in Europe. Herbicide resistance is increasing, and some European countries are among the most affected globally, such as Spain and France. This situation is worsening not only due to herbicide use restrictions but also due to climate change, rendering Mediterranean countries such as Spain particularly susceptible. Therefore, focus should be aimed at preventive measures, which include those not only based on integrated weed management strategies but also based on a very good knowledge of the

Abstract This book is about gardens in northern Spain and northern Portugal in the early middle ages, that part of the Iberian peninsula that lay beyond Muslim al-Andalus. Dealing with a vast area, of great geographical diversity and wide variation in climate, it spans the sixth to tenth centuries. Using archaeological, archaeobotanical, and written evidence, it shows that gardens might lie beside houses or scattered among arable fields or grouped together in garden zones. Gardens are difficult to recognize archaeologically but excavation suggests that many were terraces, as it also suggests t

Risers and sections of pipeline in free-span can be subjected to cyclic loading from flow-induced vibrations and other fluctuating forces leading to fatigue loading of the structure. Single-sided welds are of particular interest, however current design codes take a pessimistic view of their fatigue performance. Improvements in the quality of the finished weld produced by modern pipeline welding technology, and indeed advances made in knowledge about fatigue of such welds, mean that revision of the design guidance is now warranted. This paper reviews the fundamental basis of the existing S-N cu

The paper presents results of a sub-task of the STYLE project currently running within the 7th Framework EU programme by way of an overview of deterministic engineering assessment methods (EAM) used for evaluation of flawed nuclear plant components, as used in various European countries (Germany, France, UK, Netherlands, Czech Republic, Spain, Finland and Sweden). Within STYLE, several mock-up experiments are being performed on specimens containing structural features. Structural features being considered include (1) dissimilar metal welds, (2) repair welds, and (3) austenitic cladding on a fe

When a railway vehicle passes through a track with different weld irregularities at high speed, the impact loading of the vehicle coupled with the track is investigated in detail using a coupled vehicle/track model. In this model, a half vehicle is considered and modeled as a multi-body system. In the track model, a Timoshenko beam resting on discrete sleepers is applied to model each rail. Each sleeper is modeled as a rigid body accounting for its vertical, lateral, roll motions. A moving sleeper support model is used to simulate the interaction of the vehicle and the track.

In 2021, EsadeEcPol, in collaboration with the "Empieza Por Educar" Foundation (ExE), launched "Menttores", an online educational reinforcement program aimed at students from vulnerable backgrounds in response to the challenges posed by COVID-19. Over 8 weeks, 356 students aged 12-15 from 18 educational centers in Madrid and Catalonia benefited from three weekly tutoring sessions, each 50 minutes long, taught by paid-for, qualified math teachers who passed a rigorous selection and training process. Through a "Randomized Controlled Trial" (RCT), it was shown that the program achieved a signific

Grapevine yellows diseases characterized by similar symptoms have been reported in several countries including Israel, the United States, France, Italy, Spain, Germany and Australia. These diseases are among the most serious known in grapevine, but precise knowledge of the pathogens' identities and modes of their spread is needed to devise effective control stratgegies. The overall goals of this project were to develop improved molecular diagnostic procedures for detection and identification of the presumed mycoplasmalike organism (MLO) pathogens, now termed phytoplasmas, and to apply these pr

Harlequin ducks (Histrionicus histrionicus) are sea ducks that migrate inland each spring to nest along fast-flowing mountain streams. They are considered one of the most imperiled duck species in North America and occur in two distinct populations on the Atlantic and Pacific coasts. The Pacific coast population includes Washington State, where harlequin ducks breed in the Olympic, Cascade, and Selkirk Mountains. This species is designated as a Management Priority Species by the National Park Service within North Cascades National Park Service Complex (NOCA). This report summarizes harlequin d

Welded hollow spherical joint is widely used in large-span spatial structures due to its simple structure, clear mechanical behavior and convenient connection. However, a large number of sphere-pipe connection welds at the joints will inevitably produce complex welding residual stress, which will have adverse effects on the stiffness of the joints and the overall safety of the structure. Focusing on the sphere-pipe connection welds on the hollow spherical joints, this paper keeps track of the whole process of sphere-pipe welding, analyzes and summarizes the distribution law and specific distri
