Carolyn Sutterfield, Deputy Marjorie Howell, County Clerk of Washington County, Utah Pub 1013 published October 8, 1986 The Daily Spectrum praiser in the federal exchange program, said the proposal would allow BLM to consolidate these lands for better management since BLM currently has several sections that are in the middle of state lands and vice versa. He said the state is holding onto lands that have residential or commercial potential. Overall, he said the State Land Department's mission is to make money and to maintain long term yields on its assets.

The money made from these state trust lands pays for schools and other state facilities, said Fish. Assess impacts BLM is currently preparing an environmental analysis to assess possible impacts of the exchange alternatives. Lamb said a draft of this analysis and specific location maps are available for public review through Oct. 31 in the district's area offices in St. George.

ST. GEORGE A proposal to reposition public lands is being made by the Arizona State Land Department and the Bureau of Land Management on lands both entities administer on the Arizona Strip. This is part of an ongoing program throughout Arizona to consolidate land patterns for more efficient management, said BLM District Manager G. William Lamb. South of river Under the proposal, Lamb said BLM would acquire administration of about 160,000 acres of scattered lands now owned by the State of Arizona.

In exchange, the state would acquire 6,220 BLM-administered acres near Fredonia and Littlefield, the Black Rock interchange; and Mes-quite, as well as additional lands south of the Colorado River.

University President Jeffrey Holland will be the symposium's concluding seaker Saturday at 3 p.m. in the Jo-seph Smith Building Auditorium. Deadly hepatitis virus identified NEW YORK (UPI) Scientists have cracked the ge- netic code for a virus that causes a rare but deadly form; of hepatitis and discovered it resembles a virus responsl- ble for disease in coconuts.

The researchers, reporting Wednesday in the British scientific journal Nature, called the discovery "extreme-ly surprising" and said no other known human virus re-: sembles those found in plants. The discovery of the genetic code of the virus that causes hepatitis delta, commonly called "killer hepati-; tis" because it is as deadly as it is rare, paves the way for a diagnostic test, vaccine and blood screening test for the. disease, said researchers at Chiron Corp. of Emoryville, 7 -Calif. Scientists there identified the genetic code for the mys- terious virus along with researchers from the University 7 of California in San Francisco and Georgetown Universi-' ty in Washington.

No one knows for sure how many people have hepatitis -delta in the United States because the disease was only identified in 1977 and is not widely reported, said Ronald; -C. Hershow of the Centers For Disease Control in But he said the deadly form of hepatitis, which destroys; the liver, crops up among intravenous drug users and he-. mophiliacs who receive blood transfusions and has been reported in homosexuals. It is more prevalent in the Med- 7 iterranean and parts of Europe, he said. The hepatitis delta virus, which was first isolated several years ago, has the characteristic of viroids, a type of -virus responsible for a number of plant diseases, said Mi-, chael Houghton, chief researcher at Chiron.

He said the virus closely resembles a viroid that causes the disease cadang-cadang in coconut palms. "It was an extremely surprising discovery because it acts more like viroids than a human virus," he said in a telephone interview. "It raises interesting possibilities about its evolution, but we are not in any position to draw conclusions." 7 Houghton said the company may attempt to infect 7 PUBLIC NOTICES of last publication hereof.

But he said blood contamination is not a serious problem in this country because the hepatitis delta virus cannot exist without the virus that causes hepatitis a less dangerous form of hepatitis that has a mortality rate of about 1 percent. Public blood supplies are already screened for hepatitis he said.

Cancer mortality study criticized BOSTON (UPI) A highly publicized study that concluded we are losing the war against cancer was "elementary" and failed to provide a valid scientific assessment, the director of the National Cancer Institute said Wednesday. "The article contains glaring weaknesses," said Dr. Vincent T. DeVita Jr. in one of 12 letters to The New England Journal of Medicine commenting on the study.

The report, published in the journal May 8, based its conclusion on the overall mortality rate for cancer and ignored progress against certain types of cancer as well as in basic research, DeVita said. "The progress of a scientific program of the scope and dimensions of the national cancer program cannot be assessed with a unidimensional approach and a limited knowledge of the extent of the research effort," he said. "It attempts to summarize some 35 years of cancer-research experience in an elementary manner." John C. Bailar 3rd of the Harvard School of Public Health and Elaine M. Smith of the University of Iowa Medical Center, who wrote the original report, defended their findings and repeated their call for an emphasis on prevention.

"The ugly fact remains that overall cancer mortality is rising," they said in another letter written in response to the criticism. "This cannot be explained away as a statistical artifact, obscured by the clear evidence of progress here and there, or submerged by rosy rhetoric about research results still in the pipeline. And it cannot be While several researchers praised the study, most crit- icized it for placing a low value on progress against such diseases as breast cancer and juvenile cancers, relying on possibly outdated data and interpreting their informa- tion pessimistically. "I have to reject the conclusions of Bailar and Smith that emphasis in cancer research should be switched from treatment to prevention," said Dr. Gary A Ratkin of the American Society of Clinical Oncology.

"The inaccu- racies of the data-collection technique used in this article do not justify our abandoning treatment-based research efforts." Two researchers from the University of Texas School of Public Health in Houston noted that although overall death rate may have increased, the death rate from can- 7 cer under for those under age 65 has decreased. Dr. David Mann of Arlington, suggested that the overall increase im deaths from cancer may be the result of a decrease in deaths from heart disease. 1 "Perhaps falling cardiovascular mortality has 'un- masked' cancer mortality," said Mann. "In this context, a small percentage increase in cancer mortality may well represent progress." Researchers from the World Health Organization, 7 meanwhile, noted the increase in cancer deaths was not 7 limited to the United States, and agreed with Bailar and Smith in blaming smoking for much of the increase.

Hewlett Commission Secretary MICHAEL A. KIRSCH P.O. Box 1552 St. George, Utah 84770 PUB1007 Published Oct. 8, 1986 The Daily Spectrum ZIERIKZEE, Netherlands (UPI) After centuries of battling the sea, the Dutch are unveiling an immense engineering marvel to make sure the tragedy of 1953 in which 1,853 people were swept to their deaths in a flood never happens again.

On Oct. 4, Holland's Queen Beatrix will push a button in a computerized control room and a row of 62 gargantuan steel gates, each half the size of a football field, will creep guillotinelike downward, slamming the door on the North Sea. The gates are a storm surge barrier in the Eastern Scheldt river estuary, the final and most ambitious component of a network of dams, locks, sluices and dikes spanning the estuaries of Zeeland and South Holland that comprise the Delta project. The Dutch public works department estimates the 28-year project, involving 7,000 workers, cost $5 billion. Historically, the Dutch have fought an endless battle with the sea.

Sixty percent of Holland's 14.5 million people live below sea level. Twenty percent of the country has been reclaimed from the North Sea over the centuries, a feat nature has not taken kindly. "In Holland, every generation in his tor; as had a serious flood," said public vorks department engineer and spokesman Jos Geluk. The worst, however, came in 1953. On Jan.

31 of that year, residents of Holland's southern lowlands heard seal off the lowlands. I "The barrier is the most ambitious 7 civil engineering project ever under- taken," Geluk said. "Because of the 7 research required and what we learned, the barrier has done for wa ter engineering what NASA has don 7 for space exploration." The barrier spans the 5 V2 mile 7 mouth of the estuary in three sec7-7 tions, linking two man-made with the estuary's banks. It looks like a floating The "vertebrae" are 65 concrete piers, each 13 stories high-' and weighing 17,000 tons. The steel' gates, each 45 yards long, slide verti'7-' cally between the piers.

77 An elaborate stone "mattress'! -7 was laid across the channel floor to 7-support the enormous weight. At least seven specialized vessels had to be built some for only one task. 7 One hoisting barge called the -7 "Oyster" was constructed only to--; transport and lower the piers into place. Working in powerful currents, it and a sister barge settled --each pier, 25 by 50 yards at their" bases, onto the mattress within one- inch of the target. Without such pre 7 cision, the steel gates would not slide properly, Geluk said.

-7- Because Holland has no native: stone, 10 million tons of rock needed 7 to anchor the piers were imported from Germany and Scandanavia. -7v Then the world's largest floating crane lowered the gates and concrete girders atop the piers. the first radio warnings of gales developing over the North Sea at 8:15 a.m. By 5:15 p.m., tides were lapping at the limits of miles of earthen dikes. On Sunday night the dikes washed away.

The floods that resulted killed 1,853 people and inundated an area the size of Rhode Island 8 percent of the Netherlands. Geluk said the Delta project not only promises victory in keeping the sea at bay, but also preserves the delicate ecosystem of the Eastern Scheldt. Ten-foot tides work with the sun to make the estuary a "nursery room" for a plethora of sea life, Geluk said. "At low tide, expansive mud flats are exposed to the sun. At high tide, the water absorbes heat from the warm mud, raising the water temperature several degrees." The mud flats also are a popular feeding ground for migratory birds.

Original plans called for a solid earthen dam across the Eastern Scheldt. However, it would have turned the estuary into a freshwater lake and annihilated the ecosystem. Environmentalists and fishing interests forced a compromise in 1976 which caused the storm surge barrier to be built as a "movable dam," Geluk said. During normal conditions the enormous gates will remain open to allow almost free tidal flow into the estuary. But when tides become dangerously high, the gates can be closed to.
