The use of pesticides is sometimes considered to have dated from the latter half of the 19th century. However, a survey of the classical literature (Smith and Secoy, 1975) has shown that there were frequent references to chemicals and natural products which appear to have been used for the control of plant disease and for killing unwanted plants and animals. As a result of further research into...

Today, the accumulated volume of data traffic is on the verge of surpassing the accumulated volume of voice traffic in all public networks. Given the growth in the areas of wireless voice and data, we see that the combination of mobile and Internet communication constitutes the driving force behind third-generation wireless systems, which promise to support at least 144 kbit/s (384 kbit/s) in a...

Hawaii 167. Our observations confirm the hypothesis that Hawaii 167 contains a massive quantity of dust, the optical depth of which is sufficient to extinguish completely our ultraviolet view of a central, buried quasar. The submillimetre luminosity and associated dust mass of Hawaii 167 are similar to those of the ultraluminous class of infrared galaxies, supporting the existence of an evoluti...

That functional differentiation is dependent on 3D architecture has become accepted recently. Many papers over the last 50 years have shown that cells cultured in 2D are not representative of the in vivo situation. Structurally, 2D cultu...

Introduction: Upper airway resistance syndrome (UARS) is characterized by repeated number of arousals at night, and excessive daytime sleepiness or somnolence (EDS). It is often missed in classical polysomnographic diagnostic approaches and misdiagnosed as simple snoring or idiopathic hypersomnia, thereby is often left untreated. We propose that positive airway pressure (PAP), which has shown t...
