Mountain regions are characterized by complex interrelations between human and natural systems. Political socioeconomic drivers at various scales affect mountain farming systems functioning, resulting in farm structural changes (management, structure economic performance). Longitudinal studies help fully understand the dynamics of these systems, identify their main change, prepare for foreseeable future events. This study aimed to (i) analyse cattle Pyrenees from 1990 2018, (ii) different...

This international study involving seven European countries (Italy, UK, Finland, France, Spain, Greece, Turkey) was conducted to explore the relevant reasons that affect both consumer and non-consumer perceptions of sheep goat meat. Laddering means-end chain theory were applied. The results indicate consumers associate meat with a unique taste, authenticity natural production, linked values such as health enjoyment life. In contrast, non-consumers mainly feel disgusted when they think about...

Modified 1-benzylisoquinoline N-oxides can operate as molecular logic gates. The combination of dual-channel fluorescence emissions and the preferred interaction for selected chemical inputs allows one to design multifunction self-reprogrammable

A dual-channel fluorescent compound runs as a 1 : 2 digital demultiplexer (DEMUX) which can drive single signal (proton) to two different destinations photonic response; each channel be activated independently by careful selection of the excitation wavelength.

We have synthesized several new push-pull oligothiophenes based on the boron dipyrromethene (BODIPY) moiety as electron acceptor and more well-known substituted with N,N-dialkylamino functions to enhance their electron-donor ability. A complete characterization of electronic properties has been carried out; it consists photophysical, electrochemical, vibrational properties. The compounds studied after chemical treatment acids oxidation. In this regard, they can be termed NIR dyes amphoteric...

Allergic reactions towards β-lactam antibiotics pose an important clinical problem. The ability of small molecules, such as a β-lactams, to bind covalently proteins, in process known haptenation, is considered necessary for induction specific immunological response. Identification the proteins modified by β-lactams and elucidation relevance this allergic requires sensitive tools. Here we describe preparation characterization biotinylated amoxicillin analog (AX-B) tool study protein...

The European small ruminants (i.e. sheep and goats) farming sector (ESRS) provides economic, social environmental benefits to society, but is also one of the most vulnerable livestock sectors in Europe. This has diverse species, breeds, production systems products, which makes difficult have a clear vision its challenges through using conventional analyses. A multi-stakeholder multi-step approach, including 90 surveys, was used identify assess main for sustainability ESRS prioritize actions....

Agri-environmental policies in Europe are failing to sufficiently address ongoing environmental degradation, biodiversity decline, climate impacts, and societal demands for sustainability. To reverse this, policymakers, practitioners, farmers need better guidance on which specific agricultural practice/s should be promoted how adapt current practices reach the desired objectives. Here we use social valuation tools elucidate relationship between provision of key ecosystem services mountains,...

Abstract Livestock grazing systems constitute a traditional activity in mountain areas. They are adapted to vegetation growth cycles meadows, forests and grasslands, deliver ecosystem services such as open landscapes, wildfires prevention, biodiversity maintenance quality products. Climate change poses new challenge on by impacting its natural resource base. We used the model NODRIZA evaluate potential impact of three scenarios altered pasture quantity due climate (optimistic, medium worst)...

A variety of molecule-based logic gates have been developed where chemical and/or physical inputs promote molecular changes integrating up to two and focusing on Boolean interpretations derived from irreversible gates. However, reversible has its uses in quantum computing, low-power CMOS, optical DNA computing. In this paper, we demonstrate the integration three (viz., an XOR gate complementary INHIBIT gates) a single molecule as strategy toward developing molecules that can operate mode by...

Seven tetracoordinate organoboron fluorophores with heterobiaryl N,O- or N,N-chelate ligands were prepared and photophysically characterized (in toluene). The electronic variation of the heteroaromatic moiety provided a means for fine-tuning UV/vis absorption emission spectra. In most interesting cases, spectra red-shifted to maximum absorbance at wavelengths longer than 500 nm maxima between 620 660 nm. pronounced intramolecular charge-transfer character dyes yielded large Stokes shifts...

A series of boronic acid derived salicylidenehydrazone (BASHY) complexes was prepared and photophysically characterized. The dye platform can be modified by (a) electronic tuning along the cyanine-type axis via modification donor–acceptor pair (b) functional residue. On one hand, approach allows control photophysical parameters such as Stokes shift, emission color, two-photon-absorption (2PA) cross section. resulting dyes show light-up behavior in nonpolar media are characterized high...

Food consumption in Europe is changing. Red meat has been steadily decreasing the past decades. The rising interest of consumers for healthier and more sustainable products provides red producers with opportunity to differentiate their offers by ecolabels, origin health claims. This international study analyses European consumer preferences (beef, lamb goat) seven countries: Finland, France, Greece, Italy, Spain, Turkey United Kingdom. Through a choice experiment, 2900 responses were...

Silvopastoral systems combine wood perennials with forage and livestock. These multipurpose wood-pasture habitats represent an important part of European bio-cultural ecological heritage. However, their gradual disappearance due to processes farm abandonment intensification as well forestry threatens biodiversity conservation heritages. The behaviours forest owners livestock farmers determine the success silvopastoral since a productive coherence between management grazing is required for...

Livestock farming in arid rangelands constitutes a key component the agricultural sector, particularly developing countries. Farms have rapidly changed recent decades, which has resulted modification of their structure, management and economic performance. Nowadays, livestock production is threatened by climate change, coupled with impact complex interactions among social, political factors. The present study analyses main changes that occurred on farms south Tunisia from 2004 to 2019...

Livestock systems contribution to environmental change is controversial. Pasture-based are considered a sustainable alternative due their adaptation the use of local natural resources. However, they have limited productivity per product unit and, in Europe, depend on public economic support. Furthermore, heterogeneous farm structure and resources use, which may determine sustainability. We emergy accounting assess sustainability mountain pasture-based cattle analyse variability among farms....
