Plans are to let the three work full time durlno the summer on oroiects bemg conductea by MI~I orb. ' W I1am Savery depanment nead (mechanical), and Franz Rad. department head (civil). "This not onlv aives us valuable assistance on &&arch projects whlch we need, but aiso glves us a chance to Interest talented young people in our profession," said Mialiore. "Because of our increased tecnnofoglcal needs soclew IS rey- ng more and more on the work of engineers." Migi~ore'swork invoivescomputer graphics and expanding the problem-solving capabilities of the division's newly-acquired computer. Savery and Rad are investigating other eng~neeringphenomena uslng experimental techniques. Migliore stressed that basic research 1s involved tn all three pro- jects, which will require the students to work on abstract models and solutions, in addition to routine testing and data interpretation. The Students wiil be pald a salary while they are at PSU. Applications wiil be accepted through Friday. May 1 For more in- formation, contact Migliore at 229- 4261 or 229-4631. Going downtown?

Sharing the research tasks with PSU on the study entitled. "Portland Transtt Mali Impact Analysis." are the City of Portland and Trt-Met. The need for an accurate study of the transit mall's impacts is great. according to Kenneth Dueker, Direc- tor of the center. "There's been a lot of speculation about the impacts of the mail, but there IS a lack of real measurement or hard evidence about them." Federal officials want to know whether the Portland mail ex- perience could benefit other cities. quests for ~nformationabout the mall, and find themselves unable to back their contentions with real evidence. '"We're going to perform a survey of employees downtown. to deter- mine their changes in travel, and to learn about their attitudes concern- Ing the changes the mail has produced." explains Dueker. In ad- dltion. PSU staff and research asscstants at the center will look at the mall'strue impact on land values, and w~lilnterview business owners and developers who have moved their business concerns into or away from the mall area. Preparing for the next blow- Ash removal equipment designed Many Northwesterners may already have dismissed the problems of volcanic ashfalis from thelr lists of lmmedlate concerns. But the choking, dusty material whtch for a time seemed to cover everything, including city streets. remains a prime concern for two PSU researchers. Herman J. M~giioreand Robert E. Miller. englneerlng The two have been working to develop a system wh~chuses water under h~ghpressure to flood the bottom-most layer of ash deposits remaining on city streets after a vokanic eruption. By suspending the heavy ash particles in water long enough, the researchers hope the ash resldue can be more thoroughly pushed into larger, more concen- trated piles for removal by conven- tronal plows and loaders. Funded by the City of Portland. basic design of the prototype In- volves use of a straight metal tube equipped with a dozen high- pressure nozzles which can focus streams of water to spray the ~treet surface. Soeclal leas and wheels mounted dn the de;ice allow 1t.t~roil along just off the surface, wh~ie shields on the sides control overspray.

Nine Earth Sciences faculty members, responding to a survey recently compiled by John Eliot Allen. professor emeritus of geology. listed at least 68 television appearances Involving discussion of the mountaln during 1980 alone. plus 60 addltionai appearances on area radio stations. Through their efforts, television viewers and radio listeners number- ing in the hundreds of thousands in the Northwest reglon, as well as un- counted millions across the natlon. have had the beneflt of voicanlc in- terpretatlons from PSU's academic geologists on one or more oc- casions. Earth Sciences faculty members also handled an avalanche of re- qdests for personal appearances wn.cn tnek honorec o l and off cam- pus. The nine responding faculty es- timate that they gave more than 70 talks to a total of nearly 6.400 people dur~ng1980 at civlc clubs, before community groups and fraternal organizations, as well as in schools. Articles by PSU faculty appearing In scientific periodicals aiso have helped spread the volcano research story around the country. Full-scale tests of the prototype recently wereconducted, and results are being evaluated In terms of both speed and quallty of cleaning. It is hoped that by perfecting the new PSU design, it will be easier for c~ty road departments in the Northwest to remove more ash earller, before 11 Overwhelms storm dram and sewer systems.
