Metastasis, or the spread of cancer, is a major cause of death among cancer patients, he said. “Successful cancer treat ment is almost impossible when the cancer cannot be contained at its primary site,” he said. “Early detection followed by surgical removal and radia tion have good results. But the fact is — though most surgeons don’t like to hear it — that tumor cells are re leased during surgical man ipulation and sent on their way to invade other parts of the body.” The critical step in the cell’s travels following its release from the original tumor, he explained, is its attachment to a blood vessel wall, where its growth flourishes. If left to float through the body’s circu latory system without being able to attach to the wall, the tumor cell could not survive. The drug prevents the attachment apparently by sti mulating the body to produce prostacyclin, the most potent agent known to work against the clustering of platelets. Student loans followed closely Uncle Sam after defaulters United Press International In Philadelphia last year, U.S. marshals impounded a dozen cars, including a snazzy new Dodge and a recently purchased S , owned by people who had tulted on federal student loans. A few months later in Los Angeles, the U.S. attorney’s office filed suit against 90 stu dent loan defaulters, many of them doctors and lawyers. Nationwide, the government is in the process of warning 47,000 federal workers that, un less they soon start repaying de faulted loans, Uncle Sam will pocket a hunk of their pay. The federal government, af ter years of ineffective prodding for repayment of student loans, now is conducting open warfare against defaulters.

Students selecting the 7-day plan may dine three meals each day, except Sunday evening: those selecting the 5-day plan may dine three meals each day, Monday through Friday. Meals will be served in Commons. Fees are payable to the Controller of Ac counts, Fiscal Office, Coke Building. Notice dates: Commons will be open for cash business on Registration day, May 30. Meal plans will begin on the first day of class, May 31. Fees for each plan are as follows: 7 Day $195.00 May 31 through July 1 5 Day $176.00 and Plus Tax July 5 and 6 Meal plan validation will begin at 7:30 a.m., May 31, in the Commons Lobby. Fee slips will be required. faulted student loans. “Deadbeats” is the word Sen. Charles Percy, R-Ill., used to de scribe them last year in success fully pushing legislation that “We’re trying to apply pressure from all direc tions. We’re out to col lect for Uncle Sam.” — Frank Krebs, Student Loan Collection Task Force. gave the government added col lection muscle. The Debt Collection Act 1982 allows, the government to with hold 15 percent of a federal em ployee’s pay as a means of col lecting a defaulted student loan. In the past, garnishing federal wages was prohibited. Another major provision allows the government to send the defaulter’s name, Social Security number and the size of his debt to national credit bureaus, thus applying pressure on him to pay or get bad credit ratings. This winter, notices sent to defaulters warned that unless they make arrangements to re pay the government, a letter will be sent to credit bureaus. Percy’s legislation combined with a 1981 regulation that turned the screws on colleges. This measure cut off loan money to institutions with de fault rates above 25 percent and reduced loans to those with rates of 10 percent to 25 percent. , “We’re trying to apply press ure from all directions,” said Frank Krebs, a member of the Education Department’s three- year-old Student Loan Collec tion Task Force. “We’re out to collect for Uncle Sam.” As of June 30, 1981, the most recent date for which figures are available, the overall default rate on $5.7 billion of matured Na tional Direct Student Loans was 15.37 percent, down 2 percent from five years earlier. By getting the money back into the available student loan pool, collection efforts are seen as a way to ease cutbacks in the student aid being imposed as part of President Reagan’s over all austerity program.

In addition, URI is studying the economics of robots, revis ing cost-accounting methods for robot systems and including machine labor as a fourth cost of manufacturing. “These are born numb, dumb and blind,” Kelley says of robots. “There are a lot of applications where that is not sufficient. We are just beginning now to find easy and cheap solutions to basic problems. We’re trying to de velop the knowledge that says it is worth the effort.” Kelley disagrees with critics of robotics who contend the field will take jobs away from skilled workers. “There will be a negligible im pact on the workforce. In fact, it will create jobs because each robot will need someone to take care of it; it will mean job changes, not job eliminations,” he said. For example, the Robot Re search Group currently is using a brawny, orange Swedish-built ASERA robot arm with a 40,000-degree plasma arc torch to clean “grey iron” castings used in the automotive industry. Grey iron, the form of metal after it comes out of the casting process, is presently cleaned by foundry workers in noisy and dirty p hammers and fil LAW SCHOOL?
