Worldwide, there is a well-documented crisis for bees and other pollinators which represent a fundamental biotic capital for wild life conservation, ecosystem function, and crop production. Among all pollinators of the world, bees (Hymenoptera: Apoidea) constitute the major group in…

A revision of the calpionellid bio-chronostratigraphy in Western Sicily (Italy)
was carried out, in order to update the taxonomy of this group, through the
identification of some genera (Borziella, Longicollaria, Chitinoidella, Dobeniella,
Sturiella, Borzaiella and Praecalpionellites) and species (Remaniella
catalanoi…

Electrocrystallization of PbO2 on glassy carbon electrodes was studied in 1 M HNO3 + 0.1 M Pb(NO3)2 using cyclic voltammetry rotating disk electrode experiments, chronoamperometry, and scanning electron microscopy. In order to explain the experimental curves, a new theory of…

We studied the phylogeny and systematics of the tribe Paragini (Diptera: Syrphidae) using morphological and molecular data. The paper presents separate parsimony analyses of both adult morphological characters and partial DNA sequence data from mitochondrial cytochrome c oxidase I and…

The kinetics of activation and inactivation in the phototransduction pathway of developing
Xenopus
rods were studied. The gain of the activation steps in transduction (amplification) increased and photoresponses
became more rapid as the rods matured from the larval to the…

Current treatment guidelines for anxiety disorders, including panic disorder (PD), recommend either
medication or cognitive behavioural therapy (CBT).There is currently a call through the Layard
Report for significant investment to increase the availability of CBT resources. However, there are
reported…

This paper describes a method for the automatic inference of structural transfer rules to be used in a shallow-transfer machine translation (MT) system from small parallel corpora. The structural transfer rules are based on alignment templates, like those used in…

For a mobile robot that interacts with humans such as a home assistant or a tour guide robot, activities such as locating objects, following specific people, and distinguishing among different people are fundamental, yet challenging robotic vision tasks. For complex…

This paper reports on empirical research conducted to find out about higher education students’ mobile phone ownership, and the ways in which they are using their mobiles for learning. A survey with a group of first-year students has been followed…
