-4 More Dominicans Arrive At A&M On AID Program Twenty-eight new Dominican Republic students have arrived here for study under Agency for International Development-spon sored scholarships. The 28 students will start an intensive English training pro gram and enroll as regular stu dents in the School of Agricul ture next September, according to W. E. (Bill) Beach, Domini can Republic programs coordina tor of the International Pro grams Office. “We now have 67 Dominicans at A&M under AID scholar ships,” Beach noted. “This is the only AID spon sored group selected entirely on academic and leadership abili ties, without regard to language training,” he added. The group includes three staff members and eight recent grad uates of the Institute Superior Agricultura, an A&M-Ford Foun dation project; and two 1967 graduates each of the Mocha and Loyola Agricultural Schools. The other 13 are employes of the Min istry of Agriculture. The A&M contract with AID- Dominican Republic has the goal of training 100 students for bach elor degrees in agriculture, Beach pointed out. THE BATTALION Thursday, June 8, 1967 College Station, Texas Page 3 Duo Makes Central American Trek Two Texas A&M students will make a summer trek to Central America to study taxonomy and distribution of bats. Wildlife Science students Rich ard La Val of Florissant, Mo., and Terry C. Maxwell of San An- /tonio hope to capture more than 1,000 bats in Nicaragua, Hon duras and possibly El Salvador. La Val is a doctoral candidate and Maxwell is a senior. “We’re going to explore caves, streams and other places and catch bats with our hands, but terfly and mist nets,” La Val commented. “There are more than 100 different kinds of bats in that area.” Dr. Carter said a three-month research excursion to the area this fall will complete the study. La Val and Maxwell are hope ful their trip won’t be as adven turous as a recent research visit to the same area by Carter, La Val and Tom Webb, a graduate student from El Paso.

AP Wirephoto Map) New Device To Invented By EE Purify Air Scientist “We had no sooner driven into Guatemala City until we were ar rested by military authorities as suspects in the assassination of the Guatemalan Air Force'pub lic relations chief,” Carter re called. “Lt. Col. Eduardo Enrique Fi gueroa had been murdered the morning we drove into town,” he went on. “When soldiers stopped our car and found a lot of guns, we were thrown in jail without further questioning. They didn’t want to see our identification or anything. It was a real shock.” “The jail was crowded with de- . serters and other Army crimi nals,” he continued. “Everybody was fed beans in dirty plates ex cept us. The commandant of the post arrived early the next morn ing and released us immediately. He was very apologetic.” “It was an interesting experi ence,” Carter chuckled, “but we didn’t stick around long. A Texas A&M scientist has in vented a device which he hopes will aid man in curing air pol lution woes. The device, which Dr. Nicholas Gothard built after several years work on the theory, purifies air by trapping unwanted contami nating particles with an electri cal field. The laboratory model is a metal cylinder with an electrode inside. About 20,000 volts is ap plied to the system. This is about as much voltage as there is on an ordinary television set. Filled with smoke, the cylinder clears itself in a few seconds when the voltage is applied. Dr. Gothard notes there are many electrically-activated sys tems used in air purfication in commerce and industry today, “BUT THESE depend on charg ing the contaminating particle it self, perhaps by a screen, and then attracting it by a charge of opposite polarity,” he pointed out. In Dr. Gothard’s device, how ever, the particles receive no charge. They are brought to fil tering material around the cen tral electrode by what Dr. Goth ard says is a “converging electri cal field.” This is roughly simi lar to the principle whereby a comb run through the hair will pick up bits of paper. Dr. Gothard says he has ex perimented with cigarette and oil smoke, dust and water vapor and finds all are cleared from air by the device. An assistant professor of elec trical engineering at A&M, Dr. Gothard built the device during off-time hours around home. A FUTURE application might be filtering unwanted auto ex haust fumes which ultimately produce smoke. The hydrocarbons could be collected by such a de vice in the exhaust system which would operate off the car’s elec trical system. Dr. Gothard is hoping to develop several appli cations in collaboration with Don Dale of College Station. Other applications might be the removal of pollen, dust and humidity for people with aller gies. Or it could be used in cars where a combination of air con- Infrared emissions from Jupiter indicate the planet radiates four times as much energy as it gets from the sun.

Dr. Gothard notes cigarette smoke is one of the hardest things to filter with conventional devices because the individual particles are so small. From ex periments with cigarette smoke, he is confident his device does it with high efficiency. ....“IT WILL even i-emove smells “IT WILL EVEN remove smells,” Gothard said. “Blow perfume in one end and you can’t smell it at the other.” In development, higher volt ages probably will be tried. Since the attraction point of the pollution is the electrode in side the cylinder, the covering filter would have to be removed periodically. its.
