We investigate the effect of halo activity on the electrostatic field measured at ground level. We use electrostatic arguments as well as self-consistent simulations to show that, due to the screening charge in the ionosphere, the distant electrostatic field created by the uncompensated charge in a thundercloud decays exponentially rather than as the third power of the distance. Furthermore, si...

We interviewed 21 sheep farmers and evaluated their electric fences to identify problems and determine efficacy of electric fences to prevent coyote (Canis latrans) predation. Modified woven wire fences and fences of 9 high-tensile smooth wires alternating charged and grounded were most effective in preventing coyote predation. The most serious problems in fence design and maintenance were a) b...

We use a bag model to study flavoured mesonic (Qqq̄q̄) and baryonic (Qqqqq) states, where one heavy quark Q is associated with light quarks or antiquarks, and search for possible stable multiquarks. No bound state is found. However some states lie not too high above their dissociation threshold, suggesting the possibility of resonances, or perhaps bound states in improved models. 12.40.

Flawed above I n any institution like tiie NHS, where redis­ organisation is a way of life, there is an incli­ nation for the victims of change to believe that its instigators are sane and logi­ cal. The few who doubt the sanity of our leaders, be they politicians, senior managers or God-like clinicians, often tend to believe that the change induced is the product of some evil conspiracy. It is...

Blown sand is a serious problem in the district facing the Japan Sea where seasonal wind is very strong in winter. In order to prevent the blown sand, the construction technique using natural vegetations had been developed. The growth of the natural vegetations is encouraged by the improvement of sand ingredients in this method. The effects of the method were investigated by the field survey an...
