mirena cannot be removed, talk with your healthcare provider about the benefits and risks of continuing the pregnancy. if you continue your pregnancy, see your healthcare provider regularly. call your healthcare provider right away if you get flu - like symptoms, fever, chills, cramping, pain, bleeding, vaginal discharge, or fluid leaking from your vagina. these may be signs of infection. it is not known if mirena can cause long - term effects on the fetus if it stays in place during a pregnancy. you may use mirena when you are breastfeeding if more than six weeks have passed since you had your baby. if you are breastfeeding, mirena is not likely to affect the quality or amount of your breast milk or the health of your nursing baby. however, isolated cases of decreased milk production have been reported among women using progestin - only birth control pills. first, your healthcare provider will examine your pelvis to find the exact position of your uterus. your healthcare provider will then clean your vagina and cervix with an antiseptic solution, and slide a thin plastic tube containing mirena into your uterus. your healthcare provider will then remove the plastic tube, and leave mirena in your uterus. your healthcare provider will cut the threads to the right length. placement takes only a few minutes during an office visit. you may experience pain, bleeding or dizziness during and after placement. if these symptoms do not pass 30 minutes after placement, mirena may not have been placed correctly. your healthcare provider will examine you to see if mirena needs to be removed or replaced. you should check that mirena is in proper position by feeling the removal threads. you should do this after each menstrual period. first, wash your hands with soap and water. feel for the threads at the top of your vagina with your clean fingers. the threads are the only part of mirena you should feel when mirena is in your uterus. be careful not to pull on the threads. if you feel more than just the threads, mirena is not in the right position and may not prevent pregnancy. call your healthcare provider to have it removed. if you cannot feel the threads at all, ask your healthcare provider to check that mirena is still in the right place. in either case, use a non - hormonal birth control method ( such as condoms or spermicide ) until otherwise advised by your healthcare provider. call your healthcare provider if you have any questions or


that mirena is still in the right place. in either case, use a non - hormonal birth control method ( such as condoms or spermicide ) until otherwise advised by your healthcare provider. call your healthcare provider if you have any questions or concerns. otherwise, you should return to your healthcare provider for a follow - up visit 4 to 12 weeks after mirena is placed to make sure that mirena is in the right position. tampons may be used with mirena. call your healthcare provider if you have any concerns about mirena. be sure to call if you : - think you are pregnant. - have pelvic pain or pain during sex. - have unusual vaginal discharge or genital sores. - have unexplained fever. - might be exposed to sexually transmitted diseases ( stds ). - cannot feel mirena ' s threads. - develop very severe or migraine headaches. - have yellowing of the skin or whites of the eyes. these may be signs of liver problems. - have a stroke or heart attack. - or your partner becomes hiv positive. - have severe vaginal bleeding or bleeding that lasts a long time. mirena contains 52 mg of levonorgestrel. initially, levonorgestrel is released at a rate of approximately 20 mcg / day. this rate decreases progressively to half that value after 5 years. mirena ( levonorgestrel - releasing intrauterine system ), containing a total of 52 mg levonorgestrel, is available in a carton of one sterile unit ndc # 50419 - 421 - 01. each mirena is packaged together with an inserter in a thermoformed blister package with a peelable lid. mirena is supplied sterile. mirena is sterilized with ethylene oxide. do not resterilize. for single use only. do not use if the inner package is damaged or open. insert before the end of the month shown on the label. store at 25°c ( 77°f ) ; with excursions permitted between 15 – 30°c ( 59 – 86°f ) [ see usp controlled room temperature ]. sign up for - follow the medications that matter most to you - receive email notifications as soon as your medication pages are updated


dog blog promoting adoption, with breed profiles and stories. discussing dog breeds, dog - adoption, and the human - canine connection. monday, september 3, 2012 lycaon pictus : african wild dog there are dogs and then there are animals that are members of the larger family " canidae " to which wolves, dogs, jackals, foxes, and coyotes belong. the african wild dog, sometimes called the painted dog, while a canidae is not a true dog like the domesticated dogs we live with. in other words, they do not make good potential pets any more than a wolf or jackal does. but they are very handsome pack animals that live in family groups. unlike some members of the canidae family, it is the female of the african wild dog pack that leaves the pack they are born into, while the males stay in the pack they are born into. the young females search for packs which do not have actively breeding females currently in them. i ' ve also read that at times a pack of males will travel separately and encounter a pack of females... there has been speculation that a pack may break up if the pack leaders die ; however, it has been observed that the death of the leaders is just as likely to lead to new leaders rising from the pack ranks. the other observation i ' ve read that i find interesting about this animal ' s behavior is that they have evolved to avoid fighting with each other and are more likely to beg for food at the site of a kill than fight each other for the kill. the pack also allows the younger hunting members to eat first, rather than making them wait until the alpha members of the pack have eaten. hunting members of the pack will also go back to those animals that are not in the hunt - - the young, the pack member ( s ) that are watching the young, the elderly / infirm and regurgitate food to share with them. when i read these descriptions of behavior i am reminded of much of the behavior i observe in the domestic members of the canidae family who live with me and that i ' ve known. the willingness to share with other members of the pack. the more inquisitive and sometimes forthright tendencies of females. the willingness of other members of the family - pack to watch over and play with puppies. it ' s interesting to me the similarities between these very different members of the large canidae family. and of course, i cannot help but note that the african wild dog, is a lovely animal. physical


common name : henna plant parts used : leaves a middle sized or large, much - branched shrub, sometimes tree - like, branches 4 angled, usually ending in a sharp point. leaves opposite, 2 - 3 cm long, often acute and sharp - pointed. flowers small, white or pinkish, fragrant, in terminal large bunches. fruit small, size of a pea, round ; seeds many. characteristics and constituents : the leaves of lawsonia alba have certain medicinal properties. they are astringent and are used as a prophylactic against skin diseases. a decoction of leaves is used as gargle in sore throat. the paste of leaves is largely used in indian homes in headache, burning sensation in feet, etc. the leaves have also been shown to have some action against tubercular and other bacteria, and in typhoid and haemorrhagia. the plant has not, however, so far been put to much use in this manner. the bark and seeds of the plant are also reported to be used in ayurvedic and unani medicine. actions and uses : the chief use of the henna plant is as pleasant orange dye for colouring palms, nails, feet, hair, beard, even tails and limbs of animals. henna, mixed with other natural dyes, is largely used as hairdye and even for textiles. the oil obtained from its flowers is used in perfumery.


dr. jekyll and mr. hyde good and evil, right and wrong. both are seen through the eyes of john utterson, a lawyer and friend of the scientist dr. jekyll. after hearing the alarming account of the horrendous trampling of a small girl " like some damned juggernaut " by a violent man named mr. hyde, who also holds a connection to the lawyer ' s dear friend, utterson ' s curiosity gets the better of him and he begins to investigate. as he probes further into the events and the hidden life of mr. hyde, utterson slowly uncovers a terrifying and ghastly story. this is robert louis stevenson ' s harrowing tale of good and evil caught in the same person — a kind and well - respected doctor who has discovered a powerful and deadly drug. dr. jekyll has been experimenting with identity. he has developed a drug which separates the two sides of his nature, allowing him to abandon himself to his most corrupt inclinations as the monstrous mr. hyde. but gradually the journey back to goodness becomes more and more difficult, and the risk that mr. hyde will break free from dr. jekyll ' s control puts all of london in grave peril. robert louis stevenson originally wrote dr. jekyll and mr hyde as a " chilling shocker. " he then burned the draft and, upon his wife ' s advice, rewrote it as the darkly complex tale it is today. stark, skillfully woven, this fascinating novel explores the curious turnings of human character through the strange case of dr. jekyll, a kindly scientist who by night takes on his stunted evil self, mr. hyde. anticipating modern psychology, dr. jekyll and mr hyde is a brilliantly original study of man ' s dual nature — as well as an immortal tale of suspense and terror. published in 1866, dr. jekyll and mr hyde was an instant success and brought stevenson his first taste of fame. though sometimes dismissed as a mere mystery story, the book has evoked much literary admirations. vladimir nabokov likened it to madame bovary and " dead souls " as " a fable that lies nearer to poetry than to ordinary prose fiction.

1. fifty years of manned spaceflight. april marked the 50th anniversary of the first manned spaceflight by yuri gagarin aboard vostok 1 in 1961. russia continued regular launches with its soyuz becoming the only way too carry astronauts to the international space station ( iss ) and making their first unmanned launches from europe ' s spaceport at french guyana. but the crash of a progress cargo ship in august led to questions of relying too much on russia. in february, the european space agency ( esa ) successfully launched its second unmanned automated transfer vehicle ( atv ) johannes kepler to the iss. 2. end of the road for the space shuttle. atlantis touched down in july, marking the final spaceflight and the end of the space shuttle programme. it also meant that construction of the iss was essentially complete. meanwhile, as nasa ' s own manned space launches appeared to be temporarily abandoned, china ' s began to accelerate, including the launch of its own first space station module, tiangong - 1, in september. 3. big strides by commercial space companies. the growing interest in the us and beyond to turn space exploration over to private enterprise got a boost in april when nasa awarded $ 269 million to companies including spacex, sierra nevada, boeing and blue origin. meanwhile, seven years after the first successful suborbital flights by prototype spaceshipone, virgin galactic is steadily preparing to carry its first paying tourists to the edge of space. 4. new missions to deep space. nasa continued to pioneer exploration of the solar system. probes were launched both to jupiter in august ( juno ) and mars in november ( mars science laboratory, or curiosity ). in march, their messenger probe went into orbit around mercury, and in july, dawn began circling the asteroid vesta. twin grail probes to investigate the interior of the moon are arriving this weekend following a september launch. russia ' s bid to fly to mars failed when its phobos - grunt craft became stranded in earth orbit. 5. advances in astronomy. the number of planets discovered around other stars climbed above 700 as the year drew to a close including the first two earth - sized worlds discovered by nasa ' s kepler space mission and others found in the so - called habitable zones of their host suns. another boost for astronomy came with fresh support for the successor to hubble, the james webb space telescope after a battle in congress over its budget. in other astronomical news, the sun roared back into activity with many sunspots and eruptions plus the closest flypast by a giant asteroid ever


according to statistics, tragedies involving children tend to go up during the summer. one of the main reasons for this is that many times, this is the season where children encounter large bodies of water. unfortunately, these encounters sometimes end in tragedy. here ’ s how you can make sure your children having safe, enjoyable time around all bodies of water, including the pool and the beach. learn cpr ( cardiopulmonary resuscitation ) if you have children, this should be a natural skill for you to have. your local red cross or ymca is always offering certification courses. we aren ’ t endorsing this as a replacement for real courses, but there are many reputable organizations out there who have videos on youtube if you want to, at least, familiarize yourself with cpr before your next trip to the backyard or the beach. teach your kids to swim the red cross and the ymca also have swimming classes for young children. you should enroll them as soon as they are physically able, around three or four. they also have classes for parents with babies, but these are mostly for socialization. try to attend pools and beaches staffed by lifeguards when you arrive at the pool or beach, try to station yourself near a lifeguard so that your children are swimming within sight of the lifeguard at all times. this is by no means a substitute for your watchfulness, however. by doing this you are only guaranteeing that there is at least another set of eyes on your kids. if there is no lifeguard present, at least make sure there ’ s someone in your group that knows cpr, and that they are responsible for watching the younger children. make your pool kidproof we recommend not having a pool if you have a young family, but if you do, lock it up and equip would - be entry points with motion alarms. every pool should have a fence with childproof lock on it. some parents even go as far as equipping the doors that lead to the outside with motion alarms as well. all it takes is a minute for tragedy to strike.


the conquerors : the last updated 11 / 8 / 2009 11 / 25 / 2007 11 / 24 / 2007 some believe that all germanic tribes originated from scandinavian peninsula. around 1000 bc, the germanic tribes originated in scandinavia, from which they moved south. in 650 bc, the climate pushed the germanic tribes southwards into continental europe. in 105 b. c. german warriors inflicted a terrible defeat on a roman army. in 101 bc, a capable roman leader, marius, outmaneuvered the germans and defeated them. by 100 bc, they had reached the rhine area. and about two hundred years later, the danube basin, both roman borders. 52 bc, batttle of alesia, where vercingetorix and his troops were forced to yield to julius caesar in 51 bc, caesar had noted that the germanic tribes could be a threat. 45 bc, vercingetorix executed by crucifixion in rome. 9 ad, three legions under varus destroyed by arminius in the teutoburg forest. 100 ad, german tribes reach the danube river. small numbers were accepted for service with roman legions. small scale german - roman trade relations emerged involving cattle and slaves. 0 - 100 ad, the germanic tribes were not a real danger to rome : 1 ) poverty ensured poor armor and weapons 2 ) they had limited tactics, consisting of ambushes and a mass charge. 3 ) divisions into numerous small tribes meant a lack of political cooperation. 4 ) there was no real, continual government beyond the clan. western german tribes eastern tribes north of the goths, originall from sweden, lived in the balkan peninsula. they were divided into two groups. ostrogoths were the east goths. visigoths were the west goths. 300 ad, romans allow groups of west goths to cross their borders and settle. by the 300s ad, there was a continual belt of barbarian tribes all along the roman frontier. the fortified frontier ran from the north sea to the black sea. they had to give up their weapons and promise to be loyal to rome. trouble broke out between the roman officials and the west goths. the goths had to buy food at high prices. romans made slaves of many young goths. rebellion by the goths west goths rebelled against the roamns. in 378 ad, west goths defeated romans at the battle of adrianople. calvary eclipses the power of the foot soldier. in 410 ad, the visigoths, led by alaric, captured

is vitamin e good for your hair? vitamin e is good for your hair. getting the proper nutrition is essential for healthy skin and hair and vitamin e is no exception. vitamin e is recognized as a powerful antioxidant working against free radicals to prevent cell damage. for the hair follicle, vitamin e acts as an antioxidant providing physical stability to the cell membranes strengthening hair. this does not mean that you should ingest megadoses of vitamin e to get healthy hair. the key to healthy hair is a balanced and healthy diet. over supplementation of any nutritional supplement can actually cause hair loss. additional important vitamins and nutrients good for hair vitamin a : like vitamin e, vitamin a is an antioxidant working to protect hair follicle cells from free radical damage. excessive vitamin a can also cause hair loss. vitamin c : another antioxidant working to protect hair follicles from free radical damage, vitamin c has the added benefit of strengthening collagen, which is found in the hair follicles. folic acid : folic acid is responsible for hair follicle growth and cell division. selenium : deficiency of this trace mineral has been shown to inhibit hair growth. zinc : this essential mineral is critical in dna and rna development, which leads to normal hair follicle division.


© andrew testa / the new york times a push to reduce unnecessary radiation exposure from ct scans, above, nuclear medicine studies, and fluoroscopies. the fda has announced a plan to reduce patients ' unnecessary exposure to radiation from three different medical imaging tests. the three - pronged strategy will focus on increasing the safety of the devices, increasing patient awareness of risks, and improving the ability of patients and doctors to make informed decisions. the tests in question are computed tomography ( ct ) scans, nuclear medicine studies and fluoroscopy. ct scans produce three - dimensional images of different areas of the body, nuclear medicine studies involve consumption of a radioactive substance to observe its motion through the body, and fluoroscopy uses a continuous beam of radiation to produce a real - time, moving image. " the fda continues to support a strong dialogue between patients and physicians over the medical necessity and risk associated with these types of imaging studies, " the agency said. " however, like all medical procedures, ct, nuclear medicine, and fluoroscopy pose risks. " the fda chose to focus on the three procedures because together they provide the single greatest source of radiation exposure for the u. s. population. ct scans, nuclear medicine studies and fluoroscopy all deliver much higher doses than other radioactive imaging procedures, such as mammography or x - rays. for example, a single ct abdomen scan uses as much radiation as 400 chest x - rays or 800 dental x - rays. yet in spite of the risks, which according to the fda include cancer, cataracts and burns, the use of radioactive imaging tests has become much more common in the united states in recent years. " the amount of radiation americans are exposed to from medical imaging has dramatically increased over the past 20 years, " said jeffrey shuren, director of the fda ' s center for devices and radiological health. the fda plans to reduce unnecessary exposure by encouraging " appropriate justification " of all radiation tests, as well as " optimization of the radiation dose. " " working together, " said shuren, " the fda and other organizations hope to help patients get the right imaging exam, at the right time, with the right radiation dose. " under the first prong of its three - prong strategy, the fda seeks to encourage safer use of the three techniques. toward this goal, it plans to require manufacturers of radiation imaging devices to implement specific safeguards in the machines and implement standardized training for all device operators. the specific requirements to be established have yet to


fda seeks to encourage safer use of the three techniques. toward this goal, it plans to require manufacturers of radiation imaging devices to implement specific safeguards in the machines and implement standardized training for all device operators. the specific requirements to be established have yet to be determined, but might include making all devices display, record and report radiation doses and other relevant settings ; having devices issue alerts when a higher - than - normal dose is entered ; and making devices immediately add information about each test to a patient ' s permanent medical record and a national dose registry. the fda is also working with the centers for medicare and medicaid services to impose new accreditation requirements on all facilities that perform radioactive imaging, with the goal of improving oversight and safe device use. in order to improve patient awareness, the fda is working with a number of other organizations to design a patient medical imaging history card, which would record every radiation test undergone by a specific patient in a fashion similar to an immunization card. this card ( which will also be available via the fda web site ) could then be presented to physicians to inform them about the patient ' s prior lifetime radiation exposure. in service of the final goal, informed consent, the fda is encouraging the development of a national radiation dose registry so that researchers can monitor nationwide radiation exposure and help produce more targeted recommendations on when the risk of a procedure outweighs its benefits. " health care decisions made by patients and their physicians should include discussions of the medical need and associated risks for each procedure, " the agency said.


cancer stem cells are defined by three abilities : differentiation, self - renewal and their ability to seed a tumor. these stem cells resist chemotherapy and many researchers posit their role in relapse. a university of colorado cancer center study recently published in the journal stem cells, shows that melanoma cells with these abilities are marked by the enzyme aldh, and imagines new therapies to target high - aldh cells, potentially weeding the body of these most dangerous cancer creators. ' ' we ' ve seen aldh as a stem cell marker in other cancer types, but not in melanoma, and until now its function has been largely unknown, " says the paper ' s senior author, mayumi fujita, md, phd, investigator at the cu cancer center and associate professor in the department of dermatology at the cu school of medicine. fujita ' s group transplanted aldh + and aldh - melanoma cells into animal models, showing the aldh + cells were much more powerfully tumorigenic. in the same aldh + cells, the group then silenced the gene that creates this protein, finding that with aldh knocked down, melanoma cells died in cultures and lost their ability to form tumors in animal models. in cell cultures, silencing this aldh gene also sensitized melanoma cells to existing chemotherapies. when the group explored human tumor samples, they found distinct subpopulations of these aldh + cells, which made up about 0. 1 - 0. 2 percent of patients ' primary tumors. in samples of metastatic melanoma - - the most aggressive form of the disease - - the percentage of aldh + cells was greater, even over 10 percent in some tumors, further implying the powerful danger of these cells. " in these same aldh + cells, we find the markers of stem cells are upregulated and those of cell differentiation are downregulated. in addition to these clues, aldh + cells generate the heterogeneous cell types seen in the original tumor, " says fujita, meaning that in addition to self - renewal and tumorigenesis, aldh + cells fulfill the third criteria for a cancer stem cell : the ability to differentiate. the study also shows how the aldh gene and its protein act to create a cell ' s stem - like properties. " one way aldh makes a cancer stem cell is through the retinoic acid signaling pathway, " fujita says. the


the study also shows how the aldh gene and its protein act to create a cell ' s stem - like properties. " one way aldh makes a cancer stem cell is through the retinoic acid signaling pathway, " fujita says. the protein aldh leads to the overproduction of retinoic acid, which in turn binds to a cell ' s nuclear receptors and influences the expression of many of the cell ' s genes - - for example, genes involved in regulating cell survival, repair, and proliferation, all of which combine to confer chemoresistance. target cells with high aldh and you target all the downstream effects, including the retinoic acid signaling pathway. " our hope is that we can intervene in this signaling, either at the level of aldh or elsewhere in the pathway, especially to re - sensitize cells to chemotherapy. using a new drug to take away a melanoma stem cell ' s chemoresistance could boost the effectiveness of existing drugs, " fujita says. yuchun luo, katiuscia dallaglio, ying chen, william a robinson, steven e robinson, martin d mccarter, jianbin wang, rene gonzalez, david c thompson, david a norris, dennis r roop, vasilis vasiliou, mayumi fujita.

experimental private rocket makes highest test hop yet the spacex grasshopper rocket prototype vertically launched and landed in its most impressive test flight to date on dec. 17. a privately built rocket prototype that could lead to a completely reusable spaceflight system has passed its biggest test yet — a 12 - story hop and smooth landing. the experimental reusable rocket, called the grasshopper, made its highest and longest flight yet on dec. 17, marking the prototype ' s third successful test by the private spaceflight company spacex. in the latest test at spacex ' s proving grounds in macgregor, texas, the grasshopper rocket flew for 29 seconds and reached a height of more than 130 feet ( 40 meters ). a video of the grasshopper test flight shows the rocket soaring up into the texas sky, then smoothly descending to land on four spindly legs. in mid - november, the grasshopper rocket flew nearly two stories ( 17. 7 feet or 5. 4 meters ) up during its second test flight. the rocket ' s debut flight in september flew 6 feet ( 1. 8 meters ) into the air before landing. so far, all of the prototype ' s tests have been successful. with grasshopper, spacex is trying to solve a long - standing challenge with spaceflight : cost. because today ' s rockets aren ' t completely reusable, they act as expensive, one - use machines. companies are now trying to develop rockets that can both launch from and land on earth intact, in order to be flown again on future missions. grasshopper stands at 10 stories tall ( 108 feet, 32. 9 meters ) and houses the first stage of the falcon 9 rocket, the same rocket that launched the dragon capsule to the international space station earlier this year. a merlin 1d engine and a steel support structure round out the grasshopper ' s unique design. the rocket takes off like a typical vertically launched rocket, but its landing method makes it unique. grasshopper has four steel, springy legs to support its weight, allowing it to gently land in the same way it takes off. a rocket has never successfully landed intact after being launch to space. while nasa ' s space shuttles were reusable after launch, the huge 15 - story external tanks that helped them reach orbit were not recycled. spacex ultimately envisions using three recyclable components for future space travel : a rocket second stage, a rocket first stage, and a cone - shaped capsule. while most rockets today land in the ocean after


reach orbit were not recycled. spacex ultimately envisions using three recyclable components for future space travel : a rocket second stage, a rocket first stage, and a cone - shaped capsule. while most rockets today land in the ocean after reaching space, a land - based landing is preferred for this hardware. brackish seawater can cause unnecessary damage to otherwise reusable pieces of a rocket. each piece of the rocket will land separately so that they can be collected for later use. the two rocket stages ' landings will be aided by their engines and the capsule ' s descent should be cushioned by a parachute. spacex is planning more sophisticated, even higher hops for grasshopper in the coming months, company officials said. the hawthorne, calif. - based spacex is one of several companies developing new vehicles for private space travel. the company is one of two firms with nasa contracts to provide unmanned cargo deliveries to the international space station. spacex ' s $ 1. 6 billion deal with nasa calls for 12 cargo missions to the space station using the company ' s unmanned dragon capsule and falcon 9 rockets. spacex is also developing a manned version of its dragon capsule and is one of several firms competing for nasa contracts to ferry astronauts to and from low - earth orbit. about the author more from space. com


pasadena, calif. - - light - colored mounds of a mineral deposited on a volcanic cone more than three billion years ago may preserve evidence of one of the most recent habitable microenvironments on mars. observations by nasa ' s mars reconnaissance orbiter enabled researchers to identify the mineral as hydrated silica and to see its volcanic context. the mounds ' composition and their location on the flanks of a volcanic cone provide the best evidence yet found on mars for an intact deposit from a hydrothermal environment - - a steam fumarole, or hot spring. such environments may have provided habitats for some of earth ' s earliest life forms. " the heat and water required to create this deposit probably made this a habitable zone, " said j. r. skok of brown university, providence, r. i., lead author of a paper about these findings published online today by nature geoscience. " if life did exist there, this would be a promising type of deposit to entomb evidence of it - - a microbial mortuary. " no studies have yet determined whether mars has ever supported life. the new results add to accumulating evidence that, at some times and in some places, mars has had favorable environments for microbial life. this specific place would have been habitable when most of mars was already dry and cold. concentrations of hydrated silica have been identified on mars previously, including a nearly pure patch found by nasa ' s mars exploration rover spirit in 2007. however, none of those earlier findings were in such an intact setting as this one, and the setting adds evidence about the origin. skok said, " you have spectacular context for this deposit. it ' s right on the flank of a volcano. the setting remains essentially the same as it was when the silica was deposited. " the small cone rises about 100 meters ( 100 yards ) from the floor of a shallow bowl named nili patera. the patera, which is the floor of a volcanic caldera, spans about 50 kilometers ( 30 miles ) in the syrtis major volcanic region of equatorial mars. before the cone formed, free - flowing lava blanketed nearby plains. the collapse of an underground magma chamber from which lava had emanated created the bowl. subsequent lava flows, still with a runny texture, coated the floor of nili patera. the cone grew from even later flows, apparently after evolution of the underground magma had thickened its texture so that the erupted lava would mound up.

lava flows, still with a runny texture, coated the floor of nili patera. the cone grew from even later flows, apparently after evolution of the underground magma had thickened its texture so that the erupted lava would mound up. " we can read a series of chapters in this history book and know that the cone grew from the last gasp of a giant volcanic system, " said john mustard, skok ' s thesis advisor at brown and a co - author of the paper. " the cooling and solidification of most of the magma concentrated its silica and water content. " observations by cameras on the mars reconnaissance orbiter revealed patches of bright deposits near the summit of the cone, fanning down its flank, and on flatter ground in the vicinity. the brown researchers partnered with scott murchie of johns hopkins university applied physics laboratory, laurel, md., to analyze the bright exposures with the compact reconnaissance imaging spectrometer for mars ( crism ) instrument on the orbiter. silica can be dissolved, transported and concentrated by hot water or steam. hydrated silica identified by the spectrometer in uphill locations - - confirmed by stereo imaging - - indicates that hot springs or fumaroles fed by underground heating created these deposits. silica deposits around hydrothermal vents in iceland are among the best parallels on earth. murchie said, " the habitable zone would have been within and alongside the conduits carrying the heated water. " the volcanic activity that built the cone in nili patera appears to have happened more recently than the 3. 7 - billion - year or greater age of mars ' potentially habitable early wet environments recorded in clay minerals identified from orbit. nasa ' s jet propulsion laboratory, a division of the california institute of technology, pasadena, manages the mars reconnaissance orbiter for nasa. johns hopkins university applied physics laboratory provided and operates crism, one of six instruments on the orbiter. for more information about the mars reconnaissance

using the scots guide to electronics welcome to the scot ' s guide! originally, this material was intended just to help students at the university of st. andrews learn some basic electronics. however, as the material grew, i decided that it made sense for it to be openly available on the web for all to see. the basic intention is that these pages should be available via the web to anyone with a browser who wants to know more about electronics. however, under some circumstances you may make local electronic ( cache ) or printed copies. if you want to know more about this, please refer to the section on copyright lower down this page. note that this site is produced entirely by me in my ' spare time ' an as amateur activity, and is hosted by a web server at my university. you may like to check that this page ( and others on the site ) start with " http : / / www. st - and. ac. uk / ~ www _ pa / scots _ guide / " as, if not, you may be looking at an unauthorised mirror or copy that may not be accurate or up to date. if you are not sure of this, then the link http : / / www. st - and. ac. uk / ~ www _ pa / scots _ guide / intro / electron. htm should take you to the main home page of the original site at st. andrews university. this guide attempts the impossible! it tries to act as a ' discover within ' for anyone who wants to start learning electronics, and also as a useful reference for those who already know something about the subject. the goal is to cover all electronics, at all levels. this would take forever, so all i can do in practice is to add material on various topics as time permits and ensure something for everyone. so far as possible, the pages avoid the most demanding ' glitzy ' features like ' frames '. this is deliberate as i want the content to be readable on the widest possible range of browsers. for convenience, one or two pages use ' tables ' as most browsers can handle these, and they make choosing one thing from many options easier. there are, however, non - table contents pages for those who dislike tables. the items on the introduction page are roughly aimed at three levels of interest and prior knowledge. the simplest stuff is in the ' the basics ' column of the table, more detailed explanations are in the ' something to read ' column. the other items are more of a mixed


introduction page are roughly aimed at three levels of interest and prior knowledge. the simplest stuff is in the ' the basics ' column of the table, more detailed explanations are in the ' something to read ' column. the other items are more of a mixed bag. - the ' building blocks ' section explains how quite complicated circuits are achieved by combining a small selection of basic small circuits. the act a bit like the ' words ' of the language of electronics whereas the components ( resistors, etc ) are the ' letters '. - the ' circuit diagrams ' section shows how you can read the written language of electronics. - finally, ' data sheets ' provides some information on a few of the commonly used components. this part should be useful even if you ' re already into electronics as a quick reference to which pin does what, etc! there are four large sections based upon university level lecture courses : - the first eleven. this is based on the detailed notes for a series of eleven lectures that were intended as a general introduction to electronics. - radio and coherent. this set of pages concentrates on topics relevant to radio, microwave, and coherent light application areas. based upon the detailed lecture notes for a course of over 20 lectures in this topic. - analog and audio. this provides an introduction to analog electronics with a special emphasis on audio. based upon the notes of an eight lecture course with an accompanying laboratory. - information and measurement. this covers the topics of information theory, instrumentation and measurement. the approach is to explain these topics in terms of the physics upon which they are based in practice. this course uses various practical examples - e. g explanations of how cd players work, and encryption systems. there is also a set of pages which can be used as the basis of a practical labcourse for those wanting to learn electronics. most of these pages were generated on a riscos computer - yes, there * are * non - ibm, non - apple, non - unix computers! for this reason i have tried to ensure that the pages look ok on the widest possible range of browsers. similarly, i ' ve tried to make the content as diverse as possible. if you get a problem reading any of the pages,... or if you see mistakes, please bear in mind, however, that the software team of one ( me! ) is still slowly building these pages. as a result, some links aren ' t operating yet, and there are lots of pages that aren ' t written yet. i have now been producing these

the term " health information technology " ( health it ) is a broad concept that encompasses an array of technologies to store, share, and analyze health information. more and more, health care providers are using health it to improve patient care. but health it isn ' t just for health care providers. you can use health it to better communicate with your doctor, learn and share information about your health, and take actions that will improve your quality of life. health it lets you be a key part of the team that keeps you healthy. electronic health records ( ehrs ) your doctor keeps records of your health information, such as your history of diseases and which medications you ' re taking. up until now, most doctors stored these in paper files. ehrs ( sometimes called " electronic medical records " ) are electronic systems that store your health information. ehrs allow doctors to more easily keep track of your health information and may enable them to access your information when you have a problem even if their office is closed. ehrs also make it easier for your doctor to share information with specialists and others so that everyone who needs your information has it available when they need it. some ehrs may also allow you to log in to a web portal to view your own health record, lab results, and treatment plan, and to email your doctor. personal health records ( phrs ) a phr is a lot like an ehr, except that you control what kind of information goes into it. you can use a phr to keep track of information from your doctor visits, but the phr can also reflect your life outside the doctor ' s office and your health priorities, such as tracking your food intake, exercise, and blood pressure. sometimes, your phr can link with your doctor ' s ehr. a paper prescription can get lost or misread. e - prescribing allows your doctor to communicate directly with your pharmacy. this means you can go to the pharmacy to pick up medicine without having to bring the paper prescription. there are other " e - health tools " that you can use on your own, if you wish, that may be considered a part of the broader health it world. these include : personal health tools these are tools that help you check your health, get feedback, and keep track of your progress to better manage your health. examples include smartphone " apps " that can help you set and monitor fitness goals and cell phone text reminders to take your medicine on time. online communities can help people connect with one another to try to

1. some types of hpv are strongly associated with a high risk of developing cervical cancer. scientists believe that hpv initiates a process that leads, over time, to the development of cervical cancer ; and that other factors, such as cigarette smoking, poor nutrition and infection with the sexually transmitted disease chlamydia, stimulate and lay the groundwork for cervical cancer. 2. developed countries that have pap smears show a lot less cases of cervical cancer, because if it is detected it is very easy to get rid of. so in countries that aren ' t as well developed and don ' t have annual pap smear the it just goes undetected for a long time and gets to a point where nothing can be done. 3. the us have technologies such as the pap smear to test for hpv and begin treating it earlier have less cases of it compared to countries that cannot test for it. tests could prevent a person from sleeping with another knowing that they have it and also give them the chance to begin taking medications for it. there are many parts of the world that do not have these technologies and that is why the us has less incidence. 4. this hpv test can identify 13 of the high - risk types of hpv associated with the development of cervical cancer. this test, which looks for viral dna, is performed by collecting cells from the cervix and then sending them to a laboratory for analysis. the test can detect high - risk types of hpv even before there are any conclusive visible changes to the cervical cells. the test costs $ 45 to $ 70 in the usa. if these tests were cheaper more than just people who have signs and symptoms would get them preventing unknown infections from getting worse. 5. some people have said that it might impact children that are born to mothers who have received the vaccination with in a month to the birth. although they said this isn ' t due to the vaccine some people think it is. also...

raymond carver ( 1938 - 1988 ) in today ’ s society, everyone is expected to read. however, not everyone can read. many have gone through the public school system and have not learnt to read. school is usually looked upon as the place where students learn to read and as such, the classroom teacher has the responsibility to teach students the skills needed to learn to read. chall, jeannes and stall, steven ( 2001 ) believes that, ” reading is an activity characterised by the translation of symbols, or letters, into words and sentences that have meaning to the individual. ” the ultimate goal of reading is to be able to understand written material, to evaluate it, and to use it for one ’ s needs. dorothy rubin ( 1993 ) posited that, ” reading is a complex, dynamic process that involves the construction of meaning from the printed page. ” the writer believes that reading is the way in which an individual make sense of printed words. it is also their ability to interpret what is written. in order for the reader to become fluent, he or she must follow a sequence of characters arranged in a particular spatial order, for example, in the english system ; we read symbols from left to right, while in the chinese system, symbols are read from top to bottom. however, it is the duty of the reader to know the correct pattern and use it consistently. individuals who are blind can also learn to read. they can accomplish this by using the braille system, a printing method that involves raised or pinched dots. for the beginning reader to effectively learn or master the reading process ; various strategies will...

adapting agriculture to mitigate climate change. droughts in mexico to floods in pakistan and deadly heat in the us, extreme weather events are increasing due to global warming. experts have stated concern that these could lead to instability in global agriculture markets and even conflicts over food, similar to those seen in 2007 and 2008. in a recent report, the world bank studied the impacts of climate change in - depth for the countries mozambique, ethiopia, ghana, bangladesh, au lac ( vietnam ), samoa, and bolivia, and estimated that the cost for all the most vulnerable countries to adapt to climate change will be us $ 70 - 100 billion per year until 2050. warren evans – director of environment department at world bank ( m ) : reality is that climate change is a development issue. the poorest of the poor tend to be the most vulnerable to the impacts of climate change, whether it ’ s sea level rise, drought, flooding. they also are the least resilient because of their impoverished state. the world bank ’ s new study was presented by environment department director warren evans, who explained that economic development is the most cost - effective method of climate change adaptation. in particular, developing sustainable agriculture would make both adaptation and mitigation of climate change efficient, a point confirmed by a 2009 dutch study which found that a global shift to an organic vegan diet would save world governments 80 % of climate mitigation costs by 2050, or a savings of us $ 32 trillion. mr. evans ( m ) : agriculture is one of the opportunities for reducing greenhouse gas emissions. there is a tremendous amount of carbon stored in soils and in grasses and so on. right now, that is not a part of the equation in terms of getting financing to developing countries for reducing their emissions, but there ’ s a tremendous opportunity to shift agricultural practices, so that carbon is stored. supreme master tv ( f ) : and what kind of practices are you talking about? mr. evans ( m ) : well, a simple one is no - till farming, where you reduce the amount of exposure of the soils to the air, to the atmosphere. you retain a higher level of organic composition and of vegetative growth on top of the soils, proven over and over again to be a highly effective system for other systems involve changing the way the water ’ s managed, and in some cases it ’ s a matter of changing crops. our appreciation director evans and world bank for indicating ways to support the most impacted countries in mitigating global warming. may all nations help

harvard physicist sets record straight on internet carbon study a harvard researcher spent much of monday setting the record straight about his research and how it relates to google ' s energy consumption. a sunday times of london story reported that conducting two google searches generates as much carbon dioxide as boiling water, though the researcher denies singling out google. a story in the sunday times of london sent google ' s public relations machine into an advanced search for answers. the times reporters wrote about a new harvard study that examines the energy impact of web searches. the story ' s lead paragraph : " performing two google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea, according to new research. " one problem : the study ' s author, harvard university physicist alex wissner - gross, says he never mentions google in the study. " for some reason, in their story on the study, the times had an ax to grind with google, " wissner - gross told technewsworld. " our work has nothing to do with google. our focus was exclusively on the web overall, and we found that it takes on average about 20 milligrams of co2 per second to visit a web site. " and the example involving tea kettles? " they did that. i have no idea where they got those statistics, " wissner - gross said. was google burned by energy story? the times story is giving google a chance to talk about the company ' s green initiatives and its efforts to pursue cleaner energy technologies on several fronts, google spokesperson jamie yood said. " this comes from the top, from ( cofounders ) larry ( page ) and sergey ( brin ), who are really dedicated to this. there ' s an acknowledgment that google is using energy and on the business front it makes sense to get this energy cost as low as possible, " yood told technewsworld. " and on the environmental front, they are passionate about climate change and are really involved. they recognize that if we ' re going to use energy, let ' s try to figure out how to do this as minimally as possible. " that includes the use of biodiesel shuttles and electric cars to and from its mountain view, calif., campus, offering bikes for employees to ride from building to building on that campus, and using recyclable materials throughout those buildings. and when it comes to its server farms, " we do believe
