  1. Well - first one would need to know who looks at pornography.


    I would think that the situation which would lead to an increased birth rate would be if married couples viewed it together.


    Unmarried people are not inclined to want a child to result from a stimulated encounter, so they would use protection.


    I might be wrong about this, but I believe married men look at it when they are missing something in their relationship - either the wife is not as interested in sex as the man, or perhaps not as adventurous. In any case, I don't see that him becoming aroused would increase her ability or desire to procreate.


    From a woman's standpoint, I would suspect the fertility rate would increase with the amount of romantic attention - flowers, chocolates, dinner out, a walk on the beach or a moonlight cruise would be a bigger instigation than looking at a book or a film or someone else in a sexual encounter.

  2. I'm writing a story and for it' date=' I want to know if rain (or precipitation rather) is necessary for life. If rain is just the cycle (and forgive me for not knowing the true technical terms for this) is just evaporation of the ground water into clouds that cause precipitation back to the ground, then do we really rely on rain? I know crops dry up if it hasn't rained for a long period of time, but if say today was the last day for the rain due to pollution or something, would we be able to survive? Could we not irrigate? Or is it vital for it to rain?


    On a further note, what could cause the end of precipitation?[/quote']


    Well the first thing you need to do is some research so that you understand the water cycle. Here is a link from USGS.



    Read this so that you understand the whole process. Then, I suggest that you base your book on what would happen if one part of the water cycle was disrupted.


    Have you ever heard of "Chaos Theory"? It's the idea that changing one small thing causes changes all down the line that have far reaching and often unpredicatable consequences.


    Step number one - do the research - learn the water cycle. Your book will be totally unbelievable if it doesn't have a basis in fact.

  3. I think physical punishment very rarely is appropriate. When children are young, and are not able to understand reason, sometimes it is the only way to be sure they stay out of danger.


    I remember when my daughter was about three. We were on the boat, and she was put in a seat and told not to move while I helped Butch do something. I turned around, and she had not only gotten up, but was walking down the gunnel of the boat while it was underway, on the outside of the rail. I snatched her up and walloped her backside so hard she never made that mistake again.

  4. Greetings to all members of SFN


    My name is Ken Ramos. I am a retired US Navy veteran with 21.5 yrs of service to my credit. My interests are in the study of Nature' date=' in general, Protozoology, and Stream Biology. I am an amateur in all of the afore stated. I have studied Protozoology for about two years now and have only began in the study of Stream Biology. I also do macro and microphotography of my subjects. Having completed the basic requirements for education, I am a high school graduate only. Having been in the naval service, I am well traveled, or at least I think so, and have visited many places around the globe. Southeast Asia and those countries which lie or border on the Mediterranian have been the primary ports of call. However I have made a stop or two in jolly ol' England.


    I enjoy the study of the life sciences and for the most part I am self educated in my fields of interest. So, with this all having been said, I do look forward to some interesting discussion here with those having like interests in my fields of study. Thanks & Cheers! Ken Ramos[/quote']


    Hi Ken -

    Welcome. I'm sure you'll enjoy it here. I'm in a similar situation, I was once a biology major, but went instead into the family machine shop and have run it for 25 years. I became reinterested in science when the internet made exploration easy - I became especially interested in Geology due to the fact that the Chesapeake Bay Impact Crater is located in my area (or more correctly, buried beneath my area.)


    Another interesting group of critters are the archaea - especially chemosynthetic bacteria. They intrigue me because they combine the diciplines of geology and biology.

  5. a Mega-Tsunami from the Canaries is a possibility, rather strong one, though I disagree with this triggering Yellowstone. A mega-tsunami could also be triggered if the frozen methane hydrate deposits on the Atlantic Seaboard Continental shelf of the USA were to escape en masse from their current resting place and release into the atmosphere, which would cause global warming to speed up, but that is a different issue....


    Here's a NOAA page about methane hydrates:



    If you click on the "what lies beneath" icon on the left side, you will be taken to the section which contains this quote:



    An 'Active' Atlantic


    Scientists once thought that the West Coast of the United States was much more geologically active than the East Coast. In the past few years, however, geologists have discovered that the outer sloping edge of the continental shelf along the East Coast actually has the potential to cave in, or slump. If it caves in too abruptly, it could send destructive tidal waves —tsunamis— toward our coastlines. Imagine how stepping on an overfilled water balloon could cause its sides to bulge and eventually burst. In the same way, rocks on the deep sea floor could place enough pressure on soggy sediments to cause the water to blow out the sides of the continental slope.This could cause an underwater landslide, triggering giant waves. Learn more about submarine slides and tidal waves.


    Surveys of the East Coast from research submersibles found "slump scars" where the bottom had slid away. We do not know whether these slumps cause tsunamis or tidal waves, but we are able to learn more by analyzing the geological makeup of these sediment layers. I began exploring the depths off the East Coast more than 30 years ago, and reported the first findings of these slump scars. Evidence suggests that these scarring events have happened in the past; some of the scars look fairly recent. Since we now know that some tsunamis can be caused by these slumping events, it makes sense to learn more about the activity of the sea floor just off our coasts. Currently, scientists do not have enough information to envision the possibility of a major tsunami engulfing the Atlantic City Boardwalk, but we do know that the East Coast is not as static as we once thought.


    If I understand correctly, what causes methane hydrates to stay in place is temperature and pressure. I wonder if this is part of the mechanism that has caused radical climate changes in the past? If the climate starts to cool, more water is locked up in ice and sea level drops. Even though the global temperature is cooling, perhaps the ocean above the continental shelf would become warmer as it become shallower. Could warmer water and less pressure allow the methane hydrate deposits become unstable, allowing them to be released into the atmosphere, and generating slumps and tsunamis?

  6. I was about 25 and very inexperienced with handling a pick-up truck. My dad gave me some scrap cinderblocks to reinforce our canal bank. I thought I would be smart and load them close to the tail gate so I could just push them out of the truck. I was driving them home, and when I got up to 50 mph the front wheels of the truck came off the ground.

  7. Thinking about how we humans have been damaging the global ecosystem with our industrial prowess for the last few hundred years, we've definitely seen the devastating effects it can have on life forms which depend on the environment staying in its pre-industrial-revolution state. What I'm wondering, however, is how many people are of the opinion that this damage spells the doom for life altogether in the ecosystem in question such that once the damage is done, no life will be found there for an indefinite time? Because the theory of evolution would suggest an alternative scenario where life will simply adapt to suite its new environment. So, it is certainly the case that the current configuration of life in a particular environment will not survive an excess amount of damage, other configurations which thrive on the environment in such a "damaged" state will eventually sprout out. For example, if CO2 emissions continue to saturate the air at the rate it is currently at, oxygen breathing animals like ourselves will eventually die from suffocation, but with 6 billion people on Earth, there might be a small handfull who are genetically endowed with mechanisms in their respiratory system that can either tolerate CO2 or even make use of it somehow. Again, the general issue is: does environmental damage destroy life or change it? What do you think?


    Life on earth has been around on earth for at least 3.5 billion years. http://www.soutpansberg.com/geology/makgabeng.htm


    It has managed to survive depite several major extinctions, (now thought that most we due to large impacts) that wiped out nearly all species. http://palaeo.gly.bris.ac.uk/Palaeofiles/Permian/meteorites.html


    I think we can make, and are making the planet much less habitable for future generations, but I think that humans will survive our own destructiveness. We may not be able to survive the next earth shattering impact, which will happen at some time in the future.


    I do expect that some species will survive, and will flourish in a world with many open biological niches.


    In general, I think humanity is far too self-centered about our position in the ecological biosphere. We are just another species that is enjoying its heyday at the moment. Pride goeth before a fall.

  8. That is one reason the Chinese are able to make products so much cheaper than anywhere else. Their currency valuation is far different from the rest of the world's, when it comes down to what a yaun will buy.



    Sorry the link doesn't work - the original document is PDF, I tried to link to the HTML version. Go to Google and type in "Chinese Yaun Valuation"

  9. Feeling a lot better to have wrote about it really. Had a hot shower aswell lol' date=' cleared my head up (got rather evil flu atm) and feeling a lot more 'connected' to the planet at the moment.


    *smiles* :D


    Yes... spose the stuff is actually there, just obeying rules. Thats kinda cool...


    Cheers :D.


    Gonna go out and see people, see how it goes...[/quote']


    Glad you're feeling better. The flu can make you feel really spacy, as can the sudden lack of exercise. Your body creates endorphins, like a natural morphine, when you run. Maybe you were in withdrawel.

  10. I have a question, how are PBAs done? Do they just perform a cesarian and hoist the little guy out and throw him away?


    No - it is done vaginally. The baby is dismembered and pulled out in pieces. As I said in my post above, according to my gyn friends, this is not a common occurance, and reputable doctors only do it to save the mother's life.


    The thing about PBA's and abortion in general is that making them illegal will not stop them from happening. There will always be people who are willing to make money of off terrified and desperate people.


    Pregnancy for a young girl is a life altering event. It's the end of hopes for a career, and all too often a path that ends in poverty. Mothers often don't get the prenatal care they need, and far too often are on drugs, leading to the birth of a child who has far more challanges to face than growing up poor and unloved - they have psycological and neurological problems too.


    It does no good to shame the girl for indescretion - or to penalize her. If she and the father marry, they marry into poverty and view the child as the agent that brought them there.


    The loser in this situation, whether by abortion or birth, is a child nobody wanted and nobody loves.

  11. Hey guys. How long do the typical effects of food poisoning last? On Thursday I went to McDonalds for lunch and got some chicken nuggets. About an hour later' date=' I started feeling VERY nauseous and the intensity just progressed at an alarming rate. About 2.5-3 hours after eating the chicken, I began throwing up quite violently and without any way to stop it. My ribcage and chest muscles are now killing me from all that throwing up, and I've felt VERY weak. So weak, in fact, that I've fallen down twice just trying to walk a few feet towards the bathroom. I have NEVER felt this ill before. Only now, about 26 hours after eating the tainted food, have I gotten enough energy to get out of bed. Still, I cannot keep any food in my stomach and my chest muscles still hurt like crazy. I know this might sound really gross, but the gas I've been passing has reeked MUCH moreso than it typically should. I fear that if I try and take a crap, gallons of lava will come pouring out.


    My question is, do these symptoms cry out food poisoning or some other random bug? If this is food poisoning, how long will these symptoms last? I just want to return to a normal sense of being and not worry about throwing up or passing out at random moments. :-([/quote']


    Your metabolites are probably still out of whack. I always keep gatoraid in the fridge for just such an emergency - I can hold it down when I can't drink anything else, even if I can only sip it one little swallow at a time.

  12. You could have mono - that is one of the symptoms. You have that sore throat and feel crummy for a couple of weeks then it hits you like a ton of bricks. You been kissing anyone or sharing drinking/eating utensils?

  13. I've wondered about this too. Women can and do display finer motor skills' date=' and yet there are only a handful of great artists who are female. It cannot be because of a lack of artistic ability or opportunity, literature sets the great writers and poets on an equal footing despite gender and both sexes produce comparative qualities and amounts of work.


    Maybe it's just men prefer more practical and large application of talents, to show off what they can acheive, so it's good old male ego that drives the great painters and sculptors.[/quote']


    It doesn't take fine motor skills to be a great artist. As a matter of fact, too much detail can detract from what you are trying to convey. If a customer is interested in detail, they can take a photograph. An artist seeks to convey more than a replication of what the eye sees.

  14. I wonder if it has anything to do with fine motor skills. As far as I know, there is no scientific data to back this up, but my dad supervised machinists during WWII, when women, a la "Rosie the Riveter" did men's jobs. Dad said the women he supervised were better at making tiny parts - he deduced it was because their hands were smaller. I'm not sure that it is really the smallness of hands, but historically, women have done jobs that require a "lighter touch", ie embroidery and hand stitching. I wonder if they have genetically finer motor skills which enable them to do more exacting tasks - which in turn leads to more elegant handwriting.


    Of course - it could be that women just care more about perception, and think that sloppy handwriting connotates sloppy everthingelse.

  15. What is the source of your physical pain? You should try to get to the bottom of it and see if there is a way to manage it that doesn't involve narcotics.


    I have spinal stenosis - for one thing I have congenitally narrow disks in my lower back, I also have arthritis. The foramen on the sides of the vertebra through which the nerves pass are partially closed. When the nerve feels entrapped, it swells and the pain gets progressively worse. Right now, the sciatic nerve is irritated and the pain is going down my left leg all the way into my foot. I go for an epidural every 4 or 5 months. They inject cortesone into my back. I am having another in the next few days. It reduces the swelling of the nerve, and I get relief for a while without having to take so much medication. Eventually, I will have to have a "rotor rooter" job and have the foramen opened surgically.


    I had one back surgery for a herniated disk back in '89. That pain was severe and unrelenting, until I was able to have it repaired surgically - I woke up in the operating room totally free of pain - did not even have post-surgical pain.


    I'm telling you this because based on my experience, living with chronic pain can be very depressing. Right now, my back is so screwed up that I can't do my usual walking for exercise. That depresses me further, especially when I see my body, that I worked so hard on to get back in shape, getting saggy and flabby.


    After my husband died, my doctor prescribed Xanex. I think it is an anti-anxiety medication, rather than an anti-depressant. Regardless, it does make me feel much better.


    Hope you are successful in finding a treatment that will work for you.

  16. Dialysis tubing is a transparent' date=' selectively permeable layer. It is artificial.

    If we pour some sucrose solution into it, the sucrose molecules cannot escape as they are too big to do so.

    What happens if we boil the dialysis tubing? I think sucrose cannot pass through the layer either since the layer does not consist of living tissues/cells which contains living cell membrane destroyed the heating.

    Am I correct?[/quote']


    You're talking about the tubing that actually work as an artificial kidney?


    I don't know whether the material has changed, but this link http://people.hofstra.edu/faculty/sina_y_rabbany/engg81/kidney.html says the membrane used originally for dialysis was cellophane (cellulose acetate).


    If that is still the case, it contains organic components, even if they are combine with non-organic ones. I would think that boiling the tubing would cause the cellulose to break down.

  17. an iron filing, I was using an angle grinder (without protection), at 1`st I felt nothing at all, then about a week later lots of pain/irritation and a brown spot in the cornea that was getting larger daily, went to the hospital and they took it out saying I was about 2 days from loosing my eyesight! (as well as the `should have worn goggles lecture`).


    You really were lucky - that filing had started to rust in your eye.


    I had a similar experience to the pepper juice. It goes with a story.


    Many years ago - when I was about 19, I had been stringing some hot peppers for drying. My dad offered me a bunch of broken up cinder block left over from buiding construction - I lived on a canal bank that was not bulkheaded and the shoreline was eroding.


    So - I started throwing the blocks in the back of the truck. Not having had much experience with pickups or life in general, I thought it would be to my advantage to leave them close to the tailgate so I could just shove them out when I got home.


    So - as I'm driving them home, I get up to 55 and the front wheels of the truck come off the ground. At the same moment, a gnat flies in through the open window - right into my eye. I try to get it out with my finger, and discover that I still have hot pepper oil on my fingers, which I have now transferred to my eye. Of course, there are no tissues or kleenex in the old truck.


    I slowed down and got the front wheels on the ground, and managed to drive the rest of the way with tears streaming out of both eyes.

  18. Just because it hasn't happened yet doesn't mean it isn't going to happen.....do you have a link to the research on where we got this impact glass......I would like to look it over......as of yet....I'm not convinced we were ever hit by a metear....


    The latest occurance was in Tunkuska, Siberia, on June 30, 1908. If this had hit a populated area, or the ocean, millions of people would have been killed.

    some links:




    I live on top of the Chesapeake Bay Impact Crater. Read about it here:


    The impact occurred at a time of high sea level at what is now the city of Cape Charles on the Delmarva Peninsula. The resultant tsunami reached the Blue Ridge Mountains, which are 200 miles inland.



    The impact that exterminated the dinorsaurs occured on what is now the Yucatan Peninsula 65 million years ago:



    More general information on impact craters:



    Yes - the Canary Islands has the potential to cause a devasting tsunami - so does Hawaii. Yes - there is the hazard of a mega-eruption at Yellowstone.


    To see what a mega-eruption can do, read about the Deccan Traps in India.



    All of this just points to the fact that we as individuals, and humans as a species have and probably will only inhabit the earth for a very brief period of time in geological terms - which is measured in millions and billions of years.


    No one knows the hour or the means of their death - you might get hit by a falling rock, struck by lightning, or die of old age at 100 years plus. Best to make the most of the time you are here.

  19. How/In what way does climate change (increasing global temperatures) affect the Water Cycle?


    That's a big question, and one to which the entire answer is not yet known. However, GEWEX, The Global Energy & Water Cycle Experiment, is proposing to find the answers.


    Their home page:



    The goal of GEWEX:

    The goal of the GEWEX is to reproduce and predict, by means of suitable models, the variations of the global hydrological regime, its impact on atmospheric and surface dynamics, and variations in regional hydrological processes and water resources and their response to changes in the environment, such as the increase in greenhouse gases. GEWEX will provide an order of magnitude improvement in the ability to model global precipitation and evaporation, as well as accurate assessment of the sensitivity of atmospheric radiation and clouds to climate change.


    GEWEX is the core program in WCRP concerned with studying the dynamics and thermodynamics of the atmosphere and interactions with the Earth's surface. By virtue of this central role, GEWEX has links with all other WCRP projects, in particular, the Climate Variability and Predictablity (CLIVAR) Project, the Stratospheric Processes and their Role in Climate (SPARC) Project, and the Arctic Climate System Study (ACSYS)/Climate and Cryosphere (CIiC) Project. GEWEX maintains a close link to the International Geosphere-Biosphere Program (IGBP) through the International Satellite Land-Surface Climatology Project (ISLSCP) in coordinating many of the land-surface research activities.


    Thanks for asking that question - I didn't know GEWEX existed until I googled "climate forcing water cycle". There seems to be enough information there to keep us both busy reading for a long time.


    Perhaps we can continue this thread and discuss various GEWEX projects.
