idiocy of zero tolerance policies against children playing let me give. the problem there are so many teachers and school administrators across america that i bet many of you know one of them try talking them about the madness of zero tolerance a lot of people do things just because they were told to or they never thought about it before so please dear friends try to get teachers you know to actually think about it i can complain on t.v. all day long but one conversation from a friend or relative really could change many people's minds maybe but that's just my opinion.

hello and welcome to technology update despite our five senses not everything is quite what meets the eye this episode looks to shed some light on devices they give us a glimpse i was hiding just out of sight. remember the earth was the center of the universe until copernicus and galileo came along man's origins were unknown before darwin changed everything and the notion that there was something smaller than an atom was nearly unthinkable until ernest rutherford. even today the quest to gaze beneath the surface just goes on and on. recently we took a peek through the glass walls of school cause hypercube where many of russia's up and coming innovators had gathered to attend the annual prize award ceremony the competition sifted through roughly fifteen hundred clever ideas all looking to come

home with one of the five top honors winners were crowned for the top i.t. project the leading innovation for helping society as well as a trio for best idea project and production ready invention but in addition to the award ceremony there was plenty of other innovation minded activity going on the previous finalists and runners up were also invited to show off the latest developments on their path to a full fledged start up when a few government officials were on hand to get an up close and personal view of the country's leading young. competitors.

police say. a quick. evil doers. sniffer dogs.

they're great at explosives. but they have one major disadvantage a dog is really only able to work a maximum of thirty minutes before needing a rest. only. a dog. can only signal that something is there. to the explosive. very often putting their own lives at risk to do so also every dog is different simply.

field spectrometers can identify what. compounds the ones in the system so far have been selected for their usefulness in the field both here and. can add. many of those have one significant. tradition.

solid state physics scientists have developed a compact that we here at technology update hope would help us get to the bottom of some of the longest running popular soda brands got to admit that i had delusions of unlocking secrets and discovering. to my apparently untrained mind. spectroscope was the best way to get the answers that we were looking for. now in theory there's a wide array of potential methods of analysis each possessing its own benefits and shortcomings for example. exceptionally precise. and expensive then there's mass spectrometry which also carries a pretty hefty price tag. spectroscope can be less expensive complex sample prep work and excludes samples then there are traditional chemical analyses applications

of which are more limited and require extensive training in many cases though spectroscopy is the best just not for investigating. a coloring agent whose spectrum is too intense for us to observe any individual molecules vibrations that we would usually need to register in order to identify the composition of the substance in question in short the spectrum of the coloring agent makes it impossible to observe any spectra of the combinational scattering. which would be otherwise visible. but just because. it doesn't mean that the inspector. market can't perform a litany of other tests to help. colorings the results we were looking for the three main. water sugar. thank you. well this is the voice can be used for nonscientific purposes that is for practical

tasks as for example in the analysis of gemstones it's always interesting to know what impurities the gemstone has because they help us to find out more about the stone itself like to identify its origin. it sheaves this by creating and investigating what's called the scattering correctly to laser beam hits the molecules they become excited and begin to vibrate that scatters or refracts the laser light had a slightly altered wavelength the device is internal c.c.d. sensor measures the shift of the wavelength those alterations are then compared against the system's database of rom and shifts in terms of jim it allows anyone operating the inspector five thirty two to tell if they're looking at a fake or something much more precious. one of the achievements we take pride in is the high spatial resolution of devices . this becomes especially apparent when the device is attached to

a microscope. with a resolution of around one micro meter you can obtain an individual spectrum every square my current of the surface. this enables us to present ourselves as a major player on the serious scientific research device market. one of our latest achievements is measuring graphing. only devices such as ours can identify a layer of graphene which is this thin as one atom grows on the substrate material . thank you. the inspector team manages all this by employing a thirty make laser that emits a five hundred thirty two nanometer wavelength the c.c.d. sensor is designed to work at room temperature and has been specially designed to suppress other physical processes like raleigh scattering that can interfere. that

means the resulting analysis is just as accurate as anything else out there on the market and does it in a matter of seconds and it's automatic recognition software alerts us to what's right in front of our noses but a knowable without specialized equipment even at places as idyllic as moscow's patriarch's pond there are hidden dangers all around and the first to protecting yourself against this knowing the potential risks. to the plane they're actually radioactive particles everywhere they come from the sun. naturally occurring objects to drive the point home. showed elevated radioactivity from a simple. we can measure the radiation background radiation is pretty low so ciro point zero eight but it will gradually go up. the ideal for that extremely compact . was spurred on by the nuclear disaster in fukushima japan while the immediate threats to those in the vicinity were clear right away the experience has left many

people concerned about extraordinary and every day radiation. looking for a way to give people more peace of mind this moscow based innovator to work designing his own smartphone powered. device can help people better understand the risks that simply aren't visible for example the paint used in this old compass is still radioactive particles that are easily measurable but the right equipment. we already have a whole lot of software products for various smart phones. laptops books with varying levels of complexity on the market. and less expensive models more sophisticated versions. but of course the idea of checking radiation levels is far from a new one ever since people understood the risk of radioactivity there's been the

trusty but often cumbersome a geiger counter to measure it the device is characteristic clicking sound has long let the user know if the plate of food in front of him or her is safe to eat each audible click is an incoming radioactive particle being. since its introduction models have become more portable and simply taking that tradition into the future. the next version of. which we're calling conductor version. we're also working on a totally new generation of the device which will employ. at the moment though those plans are just that plans on paper to make the technological leap the company needs new investments which could be coming in the very near future. the company expects to hear back from. a sizable grant that could give them the resources they need to move those next generation radiation detectors

from paper to the production line. the companies anxious to get that going because according to certain estimations there could be a major so. we can see fairly high demand across the world. especially in southeast asia and japan recently we ordered a marketing research report from a japanese company basically based on very calculations they believe that if these devices were launched on the japanese market today in the first month we would sell around forty to fifty thousand of them and over the course of a year sales would total some five hundred thousand. from that point the market would stabilize and show its true capacity. overall. the japanese market is. ready to accept some three to six million devices per year. well annual

global demand here and again this is according to the marketing research report would likely be around ten to fifteen million devices. and as a wise man once said knowing is half the battle. enables users to note on a unified map where they found increased levels of radiation that could then in theory be used to inform government agencies or interested citizens with a handful of accidents ingrained in our collective memories that information is of concern to people all over the globe presently there are some one hundred seventy five million living within seventy five kilometers of major nuclear reactors of course everyone's hoping for fully safe operations but now your own dosimeter is never more than an arm's length away.

welcome back to technology update identifying external threat is one thing but no profession is more to gain by piri beneath the surface than medicine with each new advance scientists are leveling the playing field against seemingly unseeable foes since we can really only observe the consequences or symptoms of most illnesses doctors have always had to rely on reading between the lines they can often only narrow in on our ailments by process of elimination but on the back of many giant leaps forward in the past century m.d.'s now have a greater arsenal at their disposal. for example they can bombard our bodies with harmless alter sonic waves showing the image in real time of their high frequency poses are good for monitoring pregnancies as well as blood flow in their radioactive isotopes which allow doctors to target specific organs often to check for cancer magnetic fields have also been

mastered to keep an eye on soft tissues like the brain injured tendons but the granddaddy of them all is the x. ray which has been giving doctors a glimpse into our bones and lungs for more than one hundred years. the technique discovered merely by accident has highlighted how gaining new insight into what was previously out of reach these major dividends the technique revolutionized many diagnoses processes with oversize film images becoming a standard sight in hospitals everywhere but that's all in the past digital is the name of the game now armed with nearly instantaneous results doctors can see right away if they successfully snap the needed pic properly. more flexible apparatus make modern day technicians work almost as effortless as clicking a mouse. if we compare the latest x. ray equipment with previous models but of course the first big difference is the ability to refine an archive the images digitally. additionally it's increased the

quantity as well as the quality of diagnoses we perform. and in russia the first word x. ray technology. expo in moscow recently they showed off their latest wares they produced a range of high tech equipment all of it focused on getting past the barriers that nature's created. based in st petersburg the company is certainly no newcomer to the russian medical tech scene it was started in the late one nine hundred eighty s. by a team of engineers responsible for the first camera developed in the soviet union over the years and decades electron has slowly but surely improved and expanded the products it offers to the medical profession by the company's calculations it currently accounts for about twenty five percent of the markets in which it operates. at this point one of its main offerings is an entire set of x. ray machinery for doctors that need to get a peek on the inside accuracy and image clarity most important which requires

electrons to take certain precautions. so obviously. these are a whole number of test objects that allow us to evaluate various image parameters like this one which shows us the resolution that is the smallest objects you can see in a human body for example this test object is a specially made lead plate and has pairs of lines of different intervals within the space of one millimeter judging by how many line pairs we see we can figure out what the smallest element we can x. ray in the human body is there are also these objects that have varying densities which we used to conduct contrast sensitivity checks and there exists a great variety of. such tests. in addition to offering traditional simple static snapshots these are equipped with a linear x. ray technology that allows easy of nobility impaired patients and also enables

technicians to focus in on one spot in particular by moving the detector along with the x. ray tube linear x. rays minimize background image interference the next generation of technology that's been adopted the world over including a lot of russian hospitals that use it as well is computed to mo graffiti it involves scanning the patient's body to produce demographic images all slices of specific areas of the body then these individuals are put together and could be looked at from any number of angles and certain parameters could be measured these cross-sectional images are used for diagnostic and therapeutic purposes so that the doctor can get a full picture of the patient's condition. getting that three d. computer. isn't so easy circular scan only captures an area about twenty five millimeters wide so if the doc needs to check on a large section of the body it can take dozens of spins around the.

world over there are really only a handful of companies that are capable of producing equipment like this given the complexity and cost to develop it it should be no great surprise that here electro has teamed up with philips. this is the first full cycle innovative partnership of its kind in russia and the russian side provided some fifteen percent of the components for the most part this included things like service aleutians and associated software. but. thirty percent were in the process of increasing it to as much as fifty percent. in other words replacing foreign components with. more than five hundred. the country. exports
