The article gives an account of the “Handheld-Mode Interface for the OLPC XO Laptops” research work within OpenUsability project. The introduction of the following document expounds what the OLPC XOs are and which our research task has been. The second chapter explains the three stages of the work, from the concept to the graphic design. The achieved results are briefly summed up in the conclus...

The first consignment of crinoids received from the United States Fisheries steamer Albatross, now engaged in work among the Philippine Islands, proves to be a collection of more than usual interest. Not only does it contain a remarkably large number of new and interesting forms, but many species, heretofore known only from single more or less imperfect specimens, are represented. The littoral ...

Here {y\ = y — [y] = the fractional part of y. The number N is an integer >1. The number x0 is a given initial value such that 0 ^ Xo < 1. The number 0 is fixed. Some early references to numerical work with sequences of the type (1) are given by 0. Taussky and J. Todd in [1]. Regarding the sequence x„ as a function of Xo, I proved in [2] that for almost all x0 the sequence x„ is equidistributed...

In this study, we investigated the effect of the xanthine oxidase (XO) inhibitor, allopurinol (ALP), on cardiac dysfunction, oxidative-nitrosative stress, apoptosis, poly(ADP-ribose) polymerase (PARP) activity and fibrosis associated with diabetic cardiomyopathy in mice. Diabetes was induced in C57/BL6 mice by injection of streptozotocin. Control and diabetic animals were treated with ALP or pl...

Although the involvement of free radicals in the development of endothelial dysfunction under pathological conditions, like diabetes and hypercholesterolemia, has been proposed frequently, there is limited knowledge as to how superoxide anions (O2 ) might affect endothelial signal transduction. In this study, we investigated the effects of preincubation with the O2 -generating system xanthine o...

Vascular superoxide anion (O(2)(*-)) levels are increased in DOCA-salt hypertensive rats. We hypothesized that the endothelin (ET)-1-induced generation of ROS in the aorta and resistance arteries of DOCA-salt rats originates partly from xanthine oxidase (XO) and mitochondria. Accordingly, we blocked XO and the mitochondrial oxidative phosphorylation chain to investigate their contribution to RO...
