Surface ozone (O3) and its precursor’s gases (nitrogen monoxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOx), carbon monoxide (CO), methane (CH4) and non-methane hydrocarbons (NMHCs), and sulfur dioxide (SO2) were measured in Yanbu, Saudi Arabia from January 2004-December 2004. The annual average concentrations of O3, NO, NO2, NOx, SO2, CO, CH4, TNMHCs and THC were 22.51 ppb, 15.58 ppb, ...

1. We used information theoretic statistics [Akaike’s Information Criterion (AIC)] and regression analysis in a multiple hypothesis testing approach to assess the processes capable of explaining long-term demographic variation in a lightly exploited brook trout population in Ball Creek, NC. We sampled a 100-m-long second-order site during both spring and autumn 1991–2004, using three-pass elect...

Despite the proliferation of mobile devices, mobile connectivity is still lacking. Information access is a powerful tool in wired environments. It is even more important for mobile devices, which have limited storage capacity and are not ideal for primary information storage as they have the potential to be lost or broken. The combination of connectivity and mobility will enable users to access...

In Europe, the end of the 20 century was the period of the changing to digital systems, including television broadcasting. In Hungary the first digital terrestrial pilot transmissions were started in 1999 and the supplier company plans a start of the full services in autumn 2004, so the time is right to give a brief technical description what is it about and why is it good for us.

The offline processing of the data collected by the Belle detector has been recently upgraded to cope with the excellent performance of the KEKB accelerator. The 127 fb −1 of data (120 TB on tape) collected between autumn 2003 and summer 2004 has been processed in 2 months, thanks to the high speed and stability of the new, distributed processing scheme. We present here this new processing sche...

The relative importance of beetle species associated with Fusarium circinatum -infected Monterey pines was investigated in three Monterey pine forests along the coast of central California, USA from April to November in 2004 and 2005. Fusarium circinatum was frequently isolated from Ips mexicanus and I. plastographus . The mean percentage isolation based upon numbers of I. mexicanus and I. plas...
