incidence of hepatic metastases is greatly aug mented by either direct hepatic trauma (3) or liver damage induced by a variety of other modalities such as alteration of hepatic blood flow (4), inter ference with reticuloendothelial function (7), or cirrhosis produced with carbon tetrachioride ,(8). In addition, growth of dormant tumor cells has been stimulated by hepatic injury (5). The precise...

Two innovative control technologies for air pollution from the combustion of municipal solid waste (MSW) are discussed. The system concepts of Selective Cat­ alytic Reduction (SCR) and the Electron Beam (E­ Beam) process are presented, along with the extent of demonstrated experience. Estimated capital and op­ erating costs are calculated for each system for oper­ ation on a 1000 tons/day MSW m...

The so called ring spiral algorithm is a convenient means for gen erating and representing certain fullerenes and some other cubic poly hedra In Manolopoulos and Fowler presented a fullerene on vertices without a spiral No smaller unspirable fullerene is known In the spring of using computer Gunnar Brinkmann found the smallest cubic polyhedron without a spiral It has only vertices Here we gener...

erating orientation tuned responses in visual cortical neurons is still controversial. To address this question, the relationship between excitatory and inhibitory synaptic connections and orientation maps in ferret striate cortex was investigated by combining in vivo optical imaging and in vitro scanning laser photostimulation. Excitatory and inhibitory inputs to pyramidal cells originated pre...

In addition to the inherent challenge, driven by curiosity and the excitement of the chase, the quest for malaria vaccines has been made more imperative over the past two decades or so by pragmatic assessment of the odds in a disease which has been with mankind for millenia. Accel­ erating spread of parasite resistance to more and more drugs, with too few new molecular structures in the pipelin...

Strategic communication has progressively claimed a broader role in society, and fos-tering social capital, civic engagement, democracy. Thus, activism received much attention public relations theory practice. In the Portuguese case, PAN fits this con-cern line with new political parties founded bottom-up by activists’ opposition movements. 2015, managed to enter parliamentary system that had r...
