Significant land use changes, mainly in the form of changing agricultural practices, are transforming a semi-arid karstic environment in NE Spain that encloses numerous saline lakes (playa lakes), forming a unique habitat. The introduction of irrigation systems in an area characterized by a semiarid climate, closed basin hydrology, and karstic geology of evaporitic sediments, is changing the wa...

We introduce a new class of dynamical systems that we call "linear complementarity systerns". The evolution of these systems typically consists of a series of continuous phases separated by "events" which cause a change in dynamics and possibly a jump in the state vector. The occurrence of events is governed by certain inequalities similar to those appearing in the Linear Complementarity Proble...

The convulsant activity of pentylenetetrazol (PTZ) , is mainly due to' its ability to selectively antagonize GABA mediated post synaptic inhibition in the mammalian brain though a direct excitatory effect on neuronal membranes cannot be ruled out as a contributory factor (1). Furthermore there are reports which indicate that 5-hydroxytryptamine (5-HT) and norepinephrine (NE) playa modulatory ro...

The neats: proponents of formal-based, knowledge-intensive smart systems to revolutionize the requirements process. The eventual success of the neat approach is less certain. There are several opinions of the answer to: ‘Can the neats ever playa significant role in requirements engineering?’: a. Never – the extra effort of doing things the neat way will always exceed the payoff. b. Hardly ever ...

Meteorological data from stations around and within the Kaimai Ranges and data from temporary sites are used to characterise the climate of the ranges. Lowland climate is warm temperate with ample rainfall but the upland region is cooler, wetter and frequently enveloped in fog. Frequent fog plays an important part in the climate of upland regions. By modifying light, moisture and temperature re...
