Despite the advance of knowledge about the factors and potential mechanisms triggering
the ichthyotoxicity in microalgae, these remain unclear or are controversial for several species
(e.g. Heterosigma). Neither typical toxicity tests carried out with cell extracts nor direct
exposure to harmful species were proved suitable to unravel the mechanism of harm.
Ichthyotoxic species show a complex harmful effect on fish, which is mediated through various
mechanisms depending on the species. In this...

Water and nutrients are scarce resources in arid and semiarid ecosystems. In these regions, biological soil crusts (BSCs) occupy a large part of the soil surface in the open spaces surrounding patches of vegetation. BSCs affect physicochemical soil properties, such as aggregate stability, water retention, organic carbon (OC) and nitrogen (N) content, associated with primary ecosystem processes like water availability and soil fertility. However, the way BSCs modify soil surface and subsurface...

algorithm is a constraint-based algorithm consisting of fi ve steps where
the first step is to perform a set of (conditional) independence tests
while the remaining four steps relate to identifying the structure of the
Bayesian network using the results of the (conditional) independence
tests. In this paper, we describe a new approach to parallelization of the

We study the multiplicity of critical points for functionals which are only differentiable along some directions. We extend to this class of functionals the three critical point theorem of Pucci and Serrin and we apply it to a one-parameter family of functionals $J_\lambda$, $\lambda \in I\subset \mathbb R$. Under suitable assumptions, we locate an open subinterval of values $\lambda$ in $I$ for which $J_\lambda$ possesses at least three critical points. Applications to quasilinear boundary...

CpTiCl2, prepared in situ by manganese reduction of CpTiCl3, is an excellent new system for the Barbier-type allylation and propargylation of carbonyl compounds. It can be used in catalytic amounts when combined with Et3N•HBr/TMSBr, which act as regenerating system. The high regio- and stereoselectivity shown by this system makes it useful for prenylation and crotylation processes in synthesis of natural products.

This work aims to analyse the existence or non-existence of a decreasing rate of profit in Europe and determine the factors influencing it according to the Marxist theory of profitability. To do so, a panel data model was estimated for seven European countries over more than 60 years (from 1960 to 2021, inclusive). The results obtained allow us to verify the tendency for profitability to fall, which could lead the capitalist system to fail.

The microclimate of low-tech, unheated greenhouses in Mediterranean areas, associated with the local outdoor climate, is often outside the optimal range for most horticultural crops during both the warm and cold growing season. The use of a new hybrid system of passive cooling (evaporative screens) and heating (water-filled sleeves), in combination with an internal movable shading/thermal screen, was evaluated on a representative summer transplanted sweet pepper crop grown in perlite growing...

Tarwi (Lupinus mutabilis Sweet) is a key crop for Andean indigenous communities, offering proteins and fats. Both the pods and seeds of tarwi are consumed, either in their tender (immature) state or as dried, fully ripe seeds. Tarwi, like other Lupinus species, contains high alkaloid levels in its fruits and seeds that must be removed before consumption. This study evaluated the fat, protein, fibre, and alkaloid contents of four cultivars at five maturity stages ranging from 180 to 212 days...
