Node.js also delegates blocking tasks to other components as we saw earlier. There’s also the overhead of context switching between threads and writing applications to optimize threads resource sharing can be painful.īecause of the single-threaded model Node.js, it doesn’t need to spin off new threads for every single request. Moreover, the server itself start to slow down because of increasing load. This is also very resource-heavy if we are expecting one million concurrent users we better make sure we have enough threads to handle those requests. If a lot of users are performing blocking I/O tasks then this wait time also increases. So let’s say if we have more users visiting our sites than there are available threads then some users will need to wait until a thread frees up to get response. Main drawback of this model is handling concurrent users.

This creates a standard, single-image Image Overlay KML. Scale: this will import the full image but will scale it down to a reasonable size, so you will loose resolution.It creates a standard, single-image Image Overlay KML. This is good for testing what the full res looks like. Crop: this will let you import just a part of the image, but at full resolution.Now, when you import, Earth will detect the image size, and if it's too big, it will offer some options: You can control the image size when exporting from QGIS, though be aware that reducing from the defaults may make your image in Earth lower resolution than the original data. So if you want to make sure that anyone can view your KML/KMZ, then you'll want to limit the image size to 2048 max dimension, though for most modern machines, 4096 should be fine. Older/weaker machines may only support upto 2048x2048 pixel images. Most machines will support around 4096x4096 or 8192x8192 pixels max, though some will support higher. To see the max size in Earth Pro, go to Help menu > About Google Earth, and look for "Maximum Texture Size". Google Earth can only overlay images up to a certain size, depending on the graphics capacity of your computer. Notes on image sizes, superoverlays, etc. I almost always set my project and re-project my data to EPSG:4326 to avoid unexpected projection issues. But if you see any projection or positioning issues in Earth, then it's best to do all this with both the dataset and project coordinate reference systems set to WGS84 (EPSG:4326). Note on projections - It shouldn't matter what projection your QGIS Project and data layer use, so long as you export to "EPSG:4326 - WGS 84". If you created a SuperOverlay, it's harder to share, as you'll need to find where it saved it on your hard drive, and copy/share the entire folder.A KMZ is a compressed zip archive that bundles together the necessary KML as well as the image file, making it easy to share and open in Earth. In the save dialog, select file type KMZ, give it a file name & location, and save to your computer.If you created a single image overlay, and not a SuperOverlay, then right-click on the item in your Places list and select "Save Place As.".If you wish to save & share the KML/KMZ file. Click OK to create your image overlay, which will appear as a new item in your Places list.In the "New Image Overlay" dialog, edit the name, transparency, description, and any other settings you wish to change.If your image is bigger than a certain size, then Earth will provide options to import just a part of it, or to create a "KML SuperOverlay".If it tries to create a Photo Overlay, then your GeoTiff file does not contain correct georeferencing info. If you use drag & drop to import (usually faster), then make sure that the import dialog that comes up is for a "New Image Overlay" and not for a "New Photo Overlay". Use File > Open or File > Import, and select the filetype "GeoTIFF". This can be tricky, but try it if needed. No data values: you may need to set these if you have areas of no data that you wish to keep as transparent in the image.Select Columns if you want to set the exact pixel height and width of the image if desired. Extent: use the default extent of layer, unless you want to set it differently.File name: Choose a name and location to save to.(IMPORTANT - this creates the 3-band RGB image needed by Earth) Right-click on the layer and select Export > Save As to bring up the dialog titled "Save Raster Layer as.".Import your DTM data as a raster layer and style it as you wish. You should be able to create this by exporting a GeoTiff (image file with embedded coordinate data) from QGIS, and importing it into Google Earth Pro, which will convert to KML (or KMZ) for you. This can be done using a feature called Image Overlay (or in KML terms: GroundOverlay), which takes an image file and defines where on the globe it should be positioned. In this case, it sounds like you want to get a raster dataset into KML for viewing in Google Earth. KML was originally designed for vector data (points/lines/polygons), and many software tools will only export vector data as KML, which is why you don't always see the option in QGIS. In the intervening years, the thumbs-up gesture was mostly mentioned in reference to the Latin. So how did the meaning get swapped around? In antiquity, says Corbeill, “the thumb was hostile in the same way the middle finger was hostile, and it was a threat, just like it is now.” There’s a poem that describes a crowd gesturing towards a gladiator with an unfriendly or hostile thumb, and then the same phrase is used in other contexts where it clearly means the upturned thumb. “‘Turning the thumb’ is turning the thumb up ,” he says, “and you’ve got the ‘up’ gesture.”Īnother reason we know the thumbs-up was the kill signal was a gesture known as the infestus pollex or hostile thumb, which is mentioned in texts but, again, isn’t pictured. He’s got a fist with his thumb pressing down on it.”įor example, the word for turning also means turning a limb in question on the joint, but doing the modern thumbs-down gesture involves turning the wrist, not the thumb. “And right underneath, one of the referees is pressing his thumb. There’s two referees around them breaking up the battle and up above it says, in Latin, STANTES MISSI, which means ‘let the men who are still standing be released,'” he says. “What’s great about these is that they often have text accompanying them, so what you see very clearly is two gladiators fighting to a standstill. “A thumb can press or be pressed, it works both ways.”Ĭorbeill located an example of what exactly the gesture might look in Nîmes, in southern France, when he found an appliqué medallion that shows a scene from a gladiatorial battle. “The verb premere in latin is just as ambiguous as ‘press’ in English,” he says. The Latin term for the gesture of approval, Corbeill explains, is pollices premere, which means “press your thumbs” and has been described by Pliny the Elder as a common gesture of good wishes. = JS stack trace = Security context: 0x2b1fb0cf781 1: SparseJoinWithSeparatorJS(aka SparseJoinWithSeparatorJS) (this=0x2b1fb004381 ,w=0x27ccaea84051 ,F=0x$ġ69c16cf19 ,x=53665,I=0x2b1fb0b7931 ,J=0圆169c16da19 )Ģ: DoJoin(aka DoJoin) [pc=0x1e08428f12.Historical confusion about that thumb-pressing gesture exposes just how difficult it can be to track the evolution of body language. stream-to-file ± memplot node bin/cli.js -m /srv/files/Bilder -d database.json $ memplot exiftool-json-db -m /srv/files/Bilder -d database.json If this is due to metadata being kept in memory, maybe something like SQLite would be helpful?

What type of symmetry do annelids and arthropods have A distinguishing characteristic shared by annelids and arthropods is their body segmentation. Together with the emerging results on the conservation of segmentation genes, these results reinforce the hypothesis that Urbilateria had a segmented trunk developing through posterior addition. the development of the annelids and the arthropods, for in these animals there is. Annelids and arthropods are also protostomes, that is, the embryonic blastopore develops into the mouth. In addition, caudal and even-skipped are likely involved in the posterior addition of segments. All three genes are shown to be likely involved in the building of the anteroposterior axis around the slit-like amphistomous blastopore as well as in the patterning of the terminal anus-bearing piece of the body (the pygidium). Annelids belong to the still poorly studied third large branch of the bilaterians, the lophotrochozoans, and have anatomic and developmental characteristics, such as a segmented body plan, indirect development through a microscopic ciliated larva, and building of the trunk through posterior addition, which are all hypothesized by some authors (including us) to be present already in Urbilateria, the last common ancestor of bilaterians. Annelids are a diverse group of segmented worms within Spiralia, whose embryos exhibit spiral cleavage and a variety of larval forms. In order to address the question of the conservation of posterior growth mechanisms in bilaterians, we have studied the expression patterns of the orthologues of the genes caudal, even-skipped, and brachyury in the annelid Platynereis dumerilii.

The radiotoxicity of α particles is virtually independent of the phase in the cell cycle, oxygenation, and the dose rate. Linear energy transfer of α particles emitted by 227Th and its daughter 223Ra is within the range of the optimum relative biological effectiveness. Published reports indicate that 227Th has limited myelotoxicity, can be stably chelated to its carriers and, as it decays at targeted sites, 227Th produces 223Ra that is subsequently incorporated into the areas of increased osteoblastic activity, that is, osseous metastatic lesions. 227Th-labeled molecular probes based on ligands to OST-associated receptors such as IGF-1R (insulin-like growth factor receptor 1), HER2 (human epidermal growth factor receptor 2), and PSMA (prostate-specific membrane antigen) are expected to detect and treat osseous and nonosseous sites of multifocal OST. The use of aggressive therapies in an attempt to eradicate these cells can have long-term negative consequences in these vulnerable patient populations. Moreover, multifocal OST contains tumor-initiating cells that are resistant to chemotherapy. Subjects with metastatic disease or whose disease relapses after the initial therapy have a poor prognosis. This is called Rutherford’s atom model.Osteosarcoma (OST) is the most common bone tumor in children and adolescents with a second peak of incidence in elderly adults usually diagnosed as secondary tumors in Paget's disease or irradiated bone. So it can safely be said that electrons inside the atoms of the gold foil being so light do not appreciably affect the motion of incident alpha particles and can never scatter the alpha particles to such a large angle of 180′ or to any other large angles.īy analyzing the deflection of the alpha particles and the results obtained, Rutherford put forward a model of an atom. It is to be mentioned that alpha particles are about 7000 times heavier than electrons and they strike the gold foil with tremendous speed. Besides, those alpha particles which approach directly the nucleus will encounter intense electric field and according to the Coulomb’s inverse square law these particles will be repelled by maximum force and will be scattered in the backward direction making an angle of 180°. Again, those alpha particles which tome very close to the nucleus will be repelled by the positive charge of the nucleus and will be deflected from their initial paths. So, most of the alpha particle go straight through the empty space of the atom. The probability of coming closer to the nucleus of the positively charged alpha particles is less while going through the gold foil. Electrons are distributed randomly around the nucleus. the matter.Įxplanation of the results of the experiment: According to Rutherford all the positive charges and the mass of the atom are concentrated at the center of the atom. So, the credit of discovery of nucleus goes to Rutherford Nucleus is the heart or source of energy of the atoms i.e. Scientist Rutherford named it as the nucleus. From this experiment, Rutherford reached the conclusion that total positive charges and mass of the atom were concentrated at the center of a very small space. Later on in 1913, complete agreement of Rutherford’s proposal was found with the experimental results of Geiger and Marsden. Some particles even scattered in the backward direction making 180° angle.įrom this experiment, Lord Rutherford first proposed that scattering of α-particles through large angles is only possible if all the positive charges and the mass of the atom are concentrated at the center covering only a very small space around it. In this experiment, they noticed that some alpha particles went straight through the foil and some particles were scattered making small angles and some went making the angle more than 90°. This experiment is known as the famous Rutherford’s alpha deflection experiment. In 1909, scientists Geiger and Marsden, at the suggestion of Ernest Rutherford, performed a deflection experiment of alpha-particles having an energy of 7.68 MeV emitted from the radioactive polonium, on a 6 x l0 -7 m thick gold foil. Each atom contained the same number of positive and negative charges. Within this positively charged matter, negatively charged electrons were randomly distributed. Throughout the nineteenth century, scientists had the idea that each atom was composed of positive charges and these charges were distributed all over the atom. Luckily, it's not all bad news on the European front this week. We would like to encourage all freedom-loving French citizens to visit the page and sign the petition - not only for the sake of preserving software freedom in France, but also to send out a message to other governments and legislators to think twice before they succumb to commercial interests of powerful multinationals. The leading advocate against the "loi DADVSI" is EUCD.INFO which also provides a way for readers to sign a petition against adopting the law. But for this to happen, the French citizens need to mobilise once again. Europeans have already demonstrated their ability to get together when they protested against the adoption of software patents earlier this year, so let's hope that the current attempt by the French government to adopt another controversial law will suffer the same fate. As an example, those who download the libdvdcss library to watch encrypted DVDs on Linux or find a way to make a backup copy of a copy-protected music CD might face criminal penalties.Īs a web site advocating the use of Free Software we find this trend unacceptable and worth fighting against. Once it happens, it will be illegal for French residents to circumvent any copy-protection or encryption technologies. France is the first major target and, if not prevented, it will become the first country in Europe to have a law similar to DMCA (correction: Finland is the first). Now it appears that this trend is moving across the big pond and into Europe. We have seen the dangerous trend of big businesses in the United States influencing the law - by lobbying and successfully instituting controversial protection measures, such as software patents or the infamous Digital Millennium Copyright Act (DMCA).

Where she carved her name and I carved mine Īnd in keeping with the “trails” theme that I seem to have started, there are the “Trails” about which Roy Rogers and Dale Evans sing. In the pale moonshine our hearts entwine, The song is not really a about a trail at all, but about the singer’s love for his girl, June, who lives in the Blue Ridge Mountains of Virginia. A song by Al Dubin, Edwina Coolidge, and Will Grosz tells of the Santa Fe Trail.Ī song written by Ballard MacDonald and Harry Carroll in 1913 speaks of The Trail Of The Lonesome Pine. This trail served as a vital commercial and military highway until the introduction of the railroad to Santa Fe in 1880. Yet another trail I knew about was the Santa Fe Trail, a nineteenth-century transportation route through central North America that connected Franklin, Missouri with Santa Fe, New Mexico. Based on an English lyrical song that dates back to 1640, The Old Chisholm Trail was modified into a cowboy song. A song was written about the old Chisholm Trail that dates back to the 1870s when it was among the most popular songs sung by cowboys during that era. Ellsworth, Kansas, was also considered a major influence of the trail. From 1883 to 1887, the end of the trail was Caldwell, Kansas. Later, Newton, Kansas, and Wichita, Kansas, each served as the end of the trail. From 1867 to 1871, the trail ended in Abilene, Kansas. I also knew that the old Chisholm Trail is believed to have started at Donna, Texas or at San Antonio, Texas. The western half of the trail spanned most of the future states of Idaho and Oregon. The eastern part of the Oregon Trail spanned part of the future state of Kansas and nearly all of what are now the states of Nebraska and Wyoming. I knew, for instance, that the Oregon Trail was a two thousand-mile historic east-west wagon route and emigrant trail that connected the Missouri River to valleys in Oregon. I knew about the Santa Fe Trail, the Oregon Trail, even the old Chisholm Trail, but where was the Navajo Trail? There were other trails that I could find. It is to be hoped that the same high quality will be seen in the projected 2009 DVD release of this beloved film.As I was researching the song, Along The Navajo Trail, I began to wonder just where the Navajo Trail was located. The high-quality color photography was very much in evidence in the VHS tape that MCA released in the Nineties. (This is well documented.) It remains compelling entertainment today. The film was a box office smash for Paramount, playing to packed houses in both large and small towns. In its original release, audiences reportedly burst into applause while viewing some of the color scenes. The story line is very compelling and there is the strong direction of Henry Hathaway (LIVES OF A BENGAL LANCER, KISS OF DEATH, TRUE GRIT). She is supported by two handsome newcomers, Henry Fonda and Fred MacMurray, plus veterans such as Fred Stone, Beulah Bondi, and Spanky MacFarland. There are very strong performances, particularly that of Sylvia Sidney as the backwoods mountain girl - a very convincing portrayal. Aside from the superb color photography, the film has much to recommend it. There is strong evidence to suggest that THE TRAIL OF THE LONESOME PINE was the film that really popularized color. The first Technicolor feature, BECKY SHARP, had opened the previous year (1935) but did not find audience favor. It was the second full-length feature to be produced in the newly-developed 3 strip Technicolor process. THE TRAIL OF THE LONESOME PINE (1936) is a landmark color film of considerable dramatic power that has been neglected in Hollywood history. |
