The answers are so simple and straight forward that I'm always amazed by this conflict. To begin with, large families are a characteristics of societies where child labour is needed for the familiy survival, usually ones where there's a high infant mortality. As we solve point three, the overpopulation will recede. Poor Catholic countries? Like Uganda, India, Burma, Sir Lanka. I don't know that there's an forced relationship between poverty and religion. I'd say you could find a closer fit between native language and religion. As for population, and Christianity causing poverty, I would suggest you look closer to Europe. War creates poverty. It did in Vietnam, Madagascar, Afghanistan, Angola. Let's eliminate war. By the way, from you positions, I will assume that you also believe that artificial insemination, fertility drugs, sperm banks, freezing embroyos and that whole host of population enhancing techniques should also be banned. Doesn't it worry you that this puts you in the position of supporting the Catholic Church?Return to Top

No, only partially a joke. Consider this analysis. If power reactors operate on 3% enriched uranium for three years before changing fuel rods, then you should be able to operate on 30% enriched fuel for 30 years and, since Navy power reactors use 60 to 70% enriched fuel, they should be able to operate for 60 to 70 years without a fuel change if depletion of U-235 were the only criterion. There might be a slight decrement in the transmutation of U-238 to Pu-239 however since there is less around. BTW can anyone explain why mixed oxide fuels, containing significant fractions of Pu, are not used in Navy propulsion reactors? > : Even U-238 will fission if you get the neutrons to move fast enough.

I maintain that every isotope of heavy metals (over 230 MW) is potentially fissionable if you can get the neutron to move fast enough. To thermal neutrons have energies around 500 KeV. Fast neutrons have energies in excess of 4 MeV. If you could get the neutrons to move a faster speeds of 5 to 10 MeV, you could get all of the non fission products in the fuel to fission. Pu-239 has a different thermal neutron fission cross section energy curve, from U-235 and Pu-241 has a different curve from each of these others. > : I also can never remember whether it was TMI-1 or TMI-2 which melted > : down and triggered the release of several hundred thousand gallons of > : emergency cooling water.

This is just an observation of mine that these two events happened at roughly the same time given the latency period for the delayed radiation effect. The same thing happened to the salmon in the Columbia river after the appropriate latency period, post radionuclear contamination from Hanford operations. Dennis NelsonReturn to Top

Of course, 3 kg could be a little "fudge factor," allowing for imperfect union of the fissioning mass. 10/Q, JackReturn to Top

The study, which examined transport of 2,4-D and dicamba, concluded that 3% of dislodgeable turf residues (i.e. the portion of a pesticide formulation that does not adhere to the turf) were transported to carpet dust and that 0.3% of turf residues were transported to the carpet surface. The authors reported that once on carpet surfaces the residues can come into contact with skin. According to the study, previous research has suggested that transport of pesticides into homes presents significant risks of human exposure, particularly for children who may ingest residues through hand-to-mouth behavior. Once indoors, carpets, dust and furnishings may become long-term reservoirs for pesticides because common environmental degradation factors such as sunlight, wind, rain or soil microbes are absent. In the study, researchers applied a pesticide formulation containing 2,4-D, dicamba and mecoprop (X-Gro Broadleaf Weed Killer) to sections of a lawn that had not been treated with pesticides for at least 10 years. Participants then walked on the treated plots, staggering their times and walking in different areas so that most of the treated ground was covered. They then either wiped their feet on a mat or walked directly onto indoor carpeting, both of which had never been used before. Researchers analyzed residues tracked onto the carpets at four hours, eight hours and one day after pesticide application. In addition, they measured levels of turf dislodgeable residues on the lawn at these times and over the course of several days. For the first three days after application, the researchers estimated a potential track-in rate of 4.5 micrograms of 2,4- D per day. Use of entryway mats reduced the level of pesticide residues on carpet surfaces by 25% and reduced carpet dust residues by 33%. The researchers estimated that 2,4-D residues could remain in household carpet dust for up to one year after turf application at concentrations of approximately 0.3 micrograms/square meter. The authors stated that this level is consistent with levels of 2,4-D that they found in household dust of nine suburban homes. A range of health and environmental impacts have been associated with exposure to 2,4-D, including endocrine disruption, reproductive effects, cancer and toxicity to birds and fish; impacts associated with exposure to dicamba include neurological effects, non Hodgkins' lymphoma (cancer) and mutagenicity. The authors described a recent study of 2,4-D in children's urine that compared children from a town containing a 2,4-D manufacturing plant to children from a town without such a plant. The study found 2,4-D in 18% of children from the town with the 2,4-D plant and 23% of children from the town without the plant, implying that the presence of 2,4-D was due to some factor or factors other than the manufacturing plant. The authors of the track-in study stated that "Given the fact that children's hand-to-mouth activity promotes ingestion of contaminated carpet dust, we might assume that chronic indoor exposure will follow a lawn application and may result in measurable urinary levels." The authors also pointed out that their control lawn, an area to which no herbicide was applied, offered information about spray drift levels. The study found that eight hours after application turf dislodgeable residues on the untreated plot were 2-3% of the levels found on treated turf plots at the same time. Detectable levels were also present in the carpet dust after track-in from the unsprayed plot. The authors surmised that their application gun may produce a finer aerosol than some commercial sprayers, which could result in more drift. They pointed out that previous agricultural drift studies have found drift levels up to 8% of the application loading rate.

The new pesticides are aimed at controlling a wide variety of pests including cockroaches, plant diseases, borers, nematodes, aphids and other insects. These registrations reflect growing trends toward greater reliance on biological pesticides than conventional pesticides because they are often more specific to the target pests and pose little or no risk to other living organisms. They also pose valuable tools for integrated pest management practices. The following is a brief description of each of the six new products: Woodstream Corp. of Lititz, Pa. was granted registration for a pheromone (trade name German Cockroach Pheromone) to control German cockroaches. It is used in boric acid bait stations as a cockroach attractant. Boric acid on the body of the cockroach causes dehydration and death. It is approved for indoor non-food areas of homes, restaurants, health care facilities, educational institutions, factories, garages, transportation and recreational vehicles, zoos, kennels, utilities and sewers. Agridyne Technologies of Columbia, Md. was granted registration for dihydroazadirachtin (trade name DAZA) a hydrogenated form of the naturally occurring azadirachtin obtained from the seeds of the neem tree, native to India and Burma. It will be approved for use indoors against numerous insects such as ants, aphids, beetle, caterpillars, crickets, sawflies, whiteflies, centipedes, nematodes and sowbugs. Outdoors it will be approved for use on bedding plants, flowers, potted plants, foliage plants, plants grown hydroponically, ornamentals, trees, shrubs, turfgrass, fiber crops, forage and fodder crops. Stine Microbial Products of Adel, Iowa was granted registration for Burkholderia cepacia isolate (trade name Blue Circle) as a fungicide for controlling damping-off disease on plant roots and seedling roots of vegetables, fruits, nuts, vine crops, spices, ornamentals, greenhouse crops, turfgrasses, flowers, bulbs and field crops. It may be applied through the irrigation system, drenching roots of seedlings or incorporating into seedbeds at planting. Monsanto Co. of St. Louis, Mo. was granted final registration for Bacillus thuringiensis CryIA(b) Delta-Endotoxin and the Genetic Material Necessary for Its Production in Corn (trade name YieldGard), a plant-pesticide for controlling or suppressing the European corn borer, the Southwestern corn borer and the corn earworm. EPA has limited annual use to l00,000 acres in Southern states. In addition, the acreage may not exceed five percent of the corn planted in any county with more than l,000 acres if cotton. These limitations were imposed to mitigate the risk of developing resistance to Bt CryIA by the corn earworm, a pest of corn, cotton, and other Southern crops. Ciba-Geigy Corp. of Greensboro, N.C. was granted registration for Bacillus thuringiensis kurstaki strain M-200 (trade name Able) for controlling lepidoperous (caterpillar) pests in tree fruits, terrestrial small fruits and vegetables, tree nuts, alfalfa, corn, cotton, soybeans, peanuts, herbs and spices and cranberries. It may be applied aerially or by ground equipment. Ecogen Inc. of Longhorne, Pa. was granted registration for Bacillus thuringiensis kurstaki strain EG7826 (trade name Lepinox) for controlling lepidopterous (caterpillar) pests of numerous terrestrial food crops, ornamental plants, turf, nursery stock, shade trees and forests. It may be applied aerially or by ground equipment. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: ENVIRO-NEWSBRIEF 970117 The following is a daily update summarizing news of interest to EPA staff.

Daily Environment Report, January 17, 1997, pAA-1. The Clinton administration will release its proposal for new global agreement on reducing greenhouse gas emissions on January 17, according to officials from the State Department and EPA. The proposal will expand on the US position paper released in December 1996, but it will not contain specific numbers for emission reductions or deadlines. Robert Wolcott, deputy assistant administrator for EPA's Office of Policy, Planning and Evaluation said the proposal would clarify several issues that were contained in the December 1996 document. The new document will include details on the administration's proposed global trading scheme for greenhouse gas emissions. It will also include a definition of what the term "binding" means in a treaty among sovereign nations, said Wolcott. Wolcott hopes academics, industry and environmental groups support the administration's goal of market based controls on greenhouse gas emissions. "Doing an ostrich number is just not going to work on this," he said. ** CONGRESS ** Senate Energy Committee Names Members to Four Subcommittees. Daily Environment Report, January 17, 1997, pA-2.

Daily Environment Report, January 17, 1997, ppA-8-9. EPA and DowElanco have agreed on a program designed to reduce the risks associated with the use of the household insecticide chlorpyrifos. John Hagaman, President and Chief Executive Officer of DowElanco sent Assistant Administrator Lynn Goldman a letter stating the company supported the 10 point program. The program requires the company to: conduct additional epidemiological research, withdraw all products from the indoor total release fogger market and direct application pet care market, revise labels to specify re-treatment intervals, and improve the training of pest control operators. Goldman had written a letter to Hagaman on January 14 that stated EPA is "pleased that DowElanco has voluntarily committed to develop an agreement to implement the risk mitigation measures." Chlorpyrifos has to go through the same reregistration process as older pesticide active ingredients. That work has not been completed. According to Hagaman's letter the company has spent "over 16 million dollars in research programs directed toward the chlorpyrifos reregistration process." "As you know, reported health concerns about chlorpyrifos involve illnesses that are common to organophosphates, most notably, vomiting, diarrhea, and nervous system disorders from acute exposure and possibility of chronic neurological disease from long-term exposures," said the Goldman letter. Hagaman stated in his letter that the company "must state unequivocally that our proposed initiatives are not prompted in any way by a conclusion that any currently labeled uses create exposures capable of causing human injury, and any attempt to portray them in this light would only make difficult their timely and effective implementation." He acknowledged that there are reports and "allegations of illness associated with chlorpyrifos," and said in the letter "this anecdotal, inquiry-based information is clearly an insufficient basis upon which to draw conclusions as to cause and effect when considered in conjunction with all available toxicological data and risk assessments." ** EPA ** EPA Officials Divided Over Design of Environmental Goals. Inside E.P.A. Weekly Report, January 17, 1997, pp11-12. Senior EPA staff are divided over proposed draft environmental goals for fiscal year 1997 according to EPA sources and agency documents. EPA Administrator Carol Browner has the final decision over whether EPA will move towards a cross-media approach, or go with an approach that retains some aspects of the current single media system. The goals have been developed by the Planning, Budget Analysis and Accountability (PBAA) group. The PBAA was formed in response to the 1993 Government Performance and Results Act, and a report by the National Academy for Public Administration. They are responsible for improving the link between long-term environmental planning and resource management. The goals selected by Browner will be the fundamental guidelines driving the new budget and will be similar to the National Environmental Goals established by the Clinton administration, said agency officials. According to a memo by Acting Chief Financial Officer Sallyanne Harper, the first option Browner would consider is the current media structure. That would "allow a smooth evolution to the new planning, budget and accountability structure for EPA...allowing agency managers, information systems and budget and planning structures to gradually change over the next few years." It will also "result in less confusion to constituent groups than option two." Option two seeks a smaller number of goals by consolidating some of the National Environmental Goals. This approach was developed by EPA's Region V office. It adopts a full multi-media approach and would collapse the national goals into six broad categories. This would result in clearer guideposts for managing activity guidelines. Sources at EPA are downplaying the significance of the decision Browner has to make.

These are excerpts from http://204.71.8.24:80/lrand/FM_Hardn.htm plus commentary. [My excerpts are for review, without permission.] =========== Begin quotes: LIVING WITHIN LIMITS & LIMITS ON LIVING Garrett Hardin on Ecology, Economy, and Ethics Copywrite Sceptic, Vol 4., No. 2 1996, pp.42-46. Interview by Frank Meile Garrett Hardin is a pioneer in the science of human ecology. He is best known for his 1968 article in Science, "The Tragedy of the Commons." Reprinted in over 100 anthologies, it is still cited by proponents of the free market as a classic analysis of the inherent failings in terms of economic loss and environmental degradation of public, as opposed to private, ownership. ========[deletions] Skeptic: You once wrote a sarcastic piece entitled, "Nobody Ever Dies from Overpopulation." Would you care to comment? Hardin: It's absolutely true. There should be a formal scientific investigation by people who are trained in that sort of thing, which I am not, of the change in attitude toward the subject of over-population and how it came about. There was a lot of concern about population in the first part of this century. It culminated, as I see it, in Paul Ehrlich's book, The Population Bomb, in 1967. Then all the attacks started from various economists and the public just got tired of it as they became aware of the fact that the people who were talking about over-population were not offering any remedies. The feeling on the part of the public was What good is it seeing a problem, if you don't offer a remedy?" The same criticism has been made of my last book, Living Within Limits. Right now we've reached a low point in getting people to take population problems seriously. But I have been encouraged by the letters to the editor I see in the local papers. The best summary of the problem is the one Ehrlich uses - name any problem that you regard as important and dangerous and you will find that unless you solve the population problem, you can't solve that one either. Population is not the sole cause, but it's a contributing cause to all the other major problems. ========[deletions] Skeptic: Reading your books or Paul Ehrlich's, one gets the feeling we're going to hell in a hurry rather than a hand basket. But doesn't Julian Simon have a point that since Plato, and certainly since Malthus, you doomsayers have always said this and you've always been proved wrong? Hardin: Not always proved wrong. Some of the things that were said have proved right. Skeptic: For example? Hardin: Here we get into an argument. Many people think that living on Manhattan all the time is not the ideal way to live. Society paints itself into a cul-de-sac of urbanization. I grew up on a farm in Missouri. When I was very young, I remember the creek running all summer long. By my teens, it ran only at the beginning of the summer and left a hole for the rest of the summer. By the mid-30s, even the water-hole was gone. My grandfather told me that when he first moved there, the water was so clear and you could see to the bottom. As far as I was concerned, all water, in creeks, rivers, and lakes, was brown. So it was a shock when I went to England and Ireland in my 50s and saw small rivers that were so clear you could see the fish. Skeptic: But the argument against your story is that we now have, along with that somewhat polluted water, more people, more goods, more services. More people are living better than ever before. So what's one dirty pond versus 100 more people with good jobs raising their families? Hardin: The important thing, and on which you can't get agreement, is the question, "Why is having more people good?" Now, if you say more people produce more goods so that there is a higher standard of living, then you've got a good argument. But suppose more people is just more people. Suppose more people means a lower quality of life? Do we simply want to maximize the number of people? Skeptic: From a Darwinian perspective, more people allows a more stratified society and more specialization of labor. In the long run, those more populous, stratified societies will displace the less populous, more egalitarian ones. It's going to be that way, whether we like it or not. Hardin: You may be right and this is the tragedy. Can we stop our built-in suicidal tendencies? All species have the blessing of enemies that keep their numbers under control. But we have been getting rid of all our enemies. We thought we'd gotten rid of all disease. We haven't quite, but if we can, by God we will. Having gotten rid of all the lions and tigers and bears, then we get rid of the micro-predators, the bacteria, and the viruses, there will be nothing to control our numbers except ourselves. If not, we will commit suicide. The Easter Island tragedy will be universalized. There will be a few people, leading a miserable life. If we control our numbers, we might be able to settle on a world population of up to 100 million, living a hell of a good life. But we're up to six billion now. That's six thousand million. This level is impossible to maintain. Skeptic: There is a certain self-satisfied negativity to much ecological writing. Julian Simon has written other books about starting your own mail order business and how to overcome depression. I just can't imagine either you or Ehrlich writing anything so upbeat and optimistic. Isn't that an inherent flaw in the ecological movement? Aren't you going to lose the argument by induced depression as your readers reach for the Prozac? Hardin: If your only goal is to win, the answer is to become another Julian Simon. I couldn't live with myself if I did that. I'd die of shame. While I may be a bearer of bad news, I try to convince people that what sounds like bad news is better than "good news" that's wrong. ======== [deletions and end quotes] ======== A comment about a common argument quoting Hardin's "The Tragedy of the Commons." Many private property enthusiasts cite Hardin's 1968 essay as evidence for privatizing National Parks, and Forests, etc. Their error in general it to equivocate the "common good", the "common goods", and the "commons". For example, a National Forest is NOT what Hardin described. His "commons" was from an old English tradition where the the land had utterly no stewardship nor ownership. Public ownership with public property rights is NOT the same as no ownership and no property rights! In fact, a National Forest is tightly regulated to prevent a Tragedy of the Commons as its frequent users well know. Another point. Many private property enthusiasts cite environmentalist's constant complaining about the stewardship of Public Lands as evidence in favor of privatization. Environmentalists trapped in the trees of the debate are often not aware this can be an honest mistake made by those who would not recognize the difference between a forest and a tree farm. In short, the reason environmentalists do not complain about private tree farms is because they are private, and also, they are farms. Perhaps "Skeptic" has noticed Hardin's feelings that in the long run, ecology will be defeated because it will not reach the mass market, will never be very "popular": Skeptic: Isn't that an inherent flaw in the ecological movement? Aren't you going to lose the argument by induced depression as your readers reach for the Prozac? Yep. And the growthmaniacs count on that. Hardin's reply? Hardin: ...While I may be a bearer of bad news, .... So Hardin, like most environmentalists, seems to miss the point. What happened to his; "living a hell of a good life"? Environmentalists are bearers of good news in a world that many people see as falling apart. The growthmaniacs' underemployment, downsizing, environmental degradation, and exploding crime is the bad news we have been seeking to AVOID. Perhaps we should spend more time communicating our grand visions of humans in harmony with the Earth? More important, shouldn't we include the values of the people who are not environmentalists? What will a balanced world bring, anyway? - We seek increasing individuals' wealth and freedom - rather than stimulating the gross economy. We look to abundance - and wholeness instead of so-called; "economic growth". - Growthmania consumes what it promises. Ecology delivers. --Douglas bashford@psnw.com -- Middle-of-the-road extremist.

Cohen's writings and 'stunts' about nuclear matters have always been 'tongue in cheek' and in direct response to the more wild claims and statistical manipulations of the anti-nuke press. I once heard a symposium he gave where he showed conclusively that building thousands of nuclear power plants would SAVE lives even with a couple 'worse case' accidents.

According to a U.P. news story, on Friday TVA had all of its power plants running at full capacity because of the cold spell. Much heating in the TVA area is either electric resistance heating or heat pump. Many people were cold, either because they had no heating or because their systems weren't up to dealing with the cold spell. From the news story: TVA officials expect record demand Friday as bone-chilling temperatures gripped many eastern and southern states. And they say Friday was the first day that all of TVA's 177 power plants were generating electricity at the same time. TVA Chairman Craven Crowell says the agency activated its Watts Bar and Browns Ferry nuclear units to help meet ``this record high demand for power.'' The two nuclear plants have been plagued by problems in the past. Preliminary calculations show a record power demand of more than 26, 500 megawatts Friday morning. Also, for the first time ever, all of TVA's 59 fossil, five nuclear and 113 hydro units were generating power to meet the peak. The average temperature in the seven-state region at the time of the peak demand was 10 degrees. The previous record peak demand was 25,995 megawatts on Feb. 5, 1996. TVA was created in 1933 to provide electricity to poor, Depression- area states in the South. Today, it is the nation's largest producer of electricity. TVA provides power to large industries and 160 power distributors who serve almost 8 million consumers in seven southeastern states. Their customers were lucky that all 177 plants were in working order at the same time. If they want to avoid trouble at unpleasant times, they need some spare capacity. Mightn't they lose some capacity if ice clogs the water intakes of some of the plants? -- John McCarthy, Computer Science Department, Stanford, CA 94305 http://www-formal.stanford.edu/jmc/progress/ He who refuses to do arithmetic is doomed to talk nonsense.Return to Top

Perhaps buy building more refined and easier to manage technologies? You can trade some performance for easy to manage passive safety. The best way of disposing of the spent nuclear fuel from former thirld world countries ought to be as fuel in accelerator driven or molten salt reactors in the well industrialized countries. Thus you turn it from a waste into an asset and when the country in question has advanced far enough they can start building and using the more challanging designs that takes care of the waste. > Not if every household took care of their own power requirements. > Households can "borrow" from the national grid if they really need > to, and add surplus power to the grid at other times.

You still need the solar panels and their support structure. You save money in grid building but looses on having to place the solar panels where there are houses and not where they give the best efficiency. The ammount of batteries needed is truly massive, its one thing to convert a few isolated houses and another to install such infrastructure in whole regions. To leave plenty of power for industry and aluminium smelters would require batteris able to store power in the Gwh range, that is about a million car size batteries per Gwh, about ten thousand tons of lead. You will need to change out and recycle all this with a few years turn around time. It adds up to a very large effort. > You didn't mention geo-thermal and wind generation. Some of those > modern windmills are quite beautiful designs and are very productive > if you have the right location. Its only possible to use geo-thermal at some locations. The only trouble with windmills is that you need about two to three thosand of them to replace a single nuclear powerplant or coal powerplant depending on the location being good or very good. It is good and well to design for single houses and small municipials but you need large ammounts of power for a city or an industrial region. It simply is tough to produce large ammounts of power from dillute sources. :-( (I would not mind it being otherwise. ) Regards, -- -- Magnus Redin Lysator Academic Computer Society redin@lysator.liu.se Mail: Magnus Redin, Björnkärrsgatan 11 B 20, 584 36 LINKöPING, SWEDEN Phone: Sweden (0)13 260046 (answering machine) and (0)13 214600Return to Top

Consider the Roman Empire : was not 'Christainised' until Emperor Constaintine (sp?) : : So the calander did not start in _AD 1_ but at some later date, 1 AD : was recongised. We can not say from this distance if then they got a : correct date. Correct. The current system did not come into use until the 6th Century, and is based upon the calculations of a monk named Dionysius Exiguus. Most other systems of dating in the late classical and mediaeval world simply placed dates in relation to the rule of various kings. ("in the nth year of xyz's rule...") The Romans themselves dated their years from the year of the traditional, legendary founding of the city of Rome. (Roman dates are given the letters AUC, from the Latin words "From the Foundation of the City") As for being certain as to whether or not Brother Dionysius got it right... well, we can prove that he was wrong, but it's impossible to fix a date precisely. The Gospel texts state that Jesus' family went to Bethlehem because of a census that was being taken by the Roman government. Various archaeological evidence from Turkey and Egypt suggest that this census got underway in 8 BCE. Also, according to the Gospels, King Herod was still alive at the time of Jesus' birth. The Jewish-Roman historian Flavius Josephus gives us a date of 4 BCE for Herod's death. (This can be dated very precisely because of Josephus' mention of a lunar eclipse at the time). Jesus was therefore born between 8 BCE and 4 BCE. Most attempts to refine this date centre on Astronomical speculation as to the exact nature of the "Star of Bethlehem" mentioned in Matthew's Gospel. Chinese records mention a comet (or "broom star") in 5 BCE and a nova (or "guest star") in 5 BCE. Perhaps the most popular current theory, that the "star" was actually a series of planetary conjunctions, would give a date in 7 BCE. David Hughes discusses these in his book _The Star of Bethlehem: An Astronomer's Confirmation_, favouring the conjunction theory. Other good articles are to be found in the Christmas editions of _New Scientist_ for 1992 and 1995, and in the _Quarterly Journal of the Royal Astronomical Society_ in 1995 (don't remember the issue).Return to Top
