![]() ![]() I upgraded to te latest 1.6.1+ release before testing.ġ) I got a JS error in aicc.js.php in the datamodel initialization I am testing some of our AICC content using the HACP protocol en found some problems. So, if anyone has tried using Moodle 1.6.1+ and got AICC courses to load perfectly, please let us know. I havent tried Apache 2.0.59 with PHP 4.4.3 and MySQL5. I couldnt find a lower version of Apache for Windows (the lowest binary file online is Apache 2.0.59). (Actually, EasyPHP will install the following using one installation file: Apache 1.3.33, My SQL 4.1.9, PHP 4.3.10 and phpmyadmin 2.6.1). I also tried installing Moodle 1.6.1+ on EasyPHP 1.8 but Moodle needs a higher version of Apache/PHP. (My installation is on my local pc, but the courses are installed in a live server and I was able to connect from my pc and pass variables such as bookmark, scores, etc). I dont have any sample system that I put online yet, but will inform you once i've done that. I installed it and tried importing an AICC file using Moodle 1.5.3+, and it WORKS!. I've used several configurations and tried many versions of Apache, Moodle, PHP, and MySQL on a Windows machine. But don't know whether its the best solution.Īfter several weeks of testing Moodle with SCORM and AICC, I found that the culprit is Apache/PHP itself. I actually was able to resolve this problem. I hope this is helpful! Please keep me in the loop on whether you make any progress. Also feel free to ask me any AICC or SCORM questions that may arise, and I'll do my best to help. If you have not already done so, I recommend at a minumum that you download the AICC/CMI Guidelines For Interoperability. To give you a brief answer to your question about the aicc_url and aicc_sid variables: aicc_url is a callback URL to which the course directs future requests to the LMS, and aicc_sid is a unique session ID identifying the student and course. Both are mandatory for courseware launch using AICC.īelow are some resources for AICC and SCORM that you may find useful. ![]() Have you considered running your courseware via SCORM or does the content need to reside on a remote content server? However, I would like to know whether anyone has in fact been able to get their remote content running on Moodle using AICC and, if so, how they did it. Since we had the flexibility of launching the courseware using SCORM, we decided to put AICC on a back-burner.

![]() Substituting the values for water density (approximately 1000 kg/m³) and acceleration due to gravity (approximately 9.8 m/s²), and setting the height (depth) to 100 meters, we get: To calculate the water pressure at a depth of 100 meters, we can use the formula for hydrostatic pressure: What is the water pressure at 100 Metres? Therefore, the water pressure at a depth of 30 meters is approximately 2.94 bars. Therefore, to convert the pressure to bars: Substituting the values for water density (approximately 1000 kg/m³) and acceleration due to gravity (approximately 9.8 m/s²), and setting the height (depth) to 30 meters, we get: To calculate the water pressure at a depth of 30 meters, you can use the formula for hydrostatic pressure: So, 1 meter of water pressure is approximately 0.0981 bars (rounded to four decimal places). Therefore, to convert 1 meter of water pressure to bars, you divide the value by the conversion factor:ġ meter of water / 10.19716213 = 0.0980665 bars To convert water pressure from meters of water to bars, you can use the following conversion: Therefore, the water pressure at a depth of 2.5 meters is approximately 24,500 Pascal (Pa). ![]() Substituting the values for water density (approximately 1000 kg/m³) and acceleration due to gravity (approximately 9.8 m/s²), and setting the height (depth) to 2.5 meters, we get: The water pressure at a depth of 2.5 meters can be calculated using the formula for hydrostatic pressure: Therefore, the water pressure at a depth of 10 meters is approximately 98,000 Pascal (Pa). Substituting the values for water density (approximately 1000 kg/m³) and acceleration due to gravity (approximately 9.8 m/s²), and setting the height (depth) to 10 meters, we get: The water pressure at a depth of 10 meters can be calculated using the formula for hydrostatic pressure: Therefore, the water pressure at a depth of 50 meters is approximately 490,000 Pascal (Pa).

Next came brothers "Reggie" Vanderbilt, who was the grandfather of CNN Anchor Anderson Cooper, and "Neily" Vanderbilt, who was not the grandfather of iconic rapper Nelly.īoth brothers spent a ton to maintain the high society lifestyle of the roaring 20s, and this dwindling supply was dispersed between even more descendants throughout the early 1900s. The Vanderbilt's net savings reached zero dollars gained by the end of William's reign, leaving the fortune stagnant at $200 million dollars. William gave hundreds of thousands of dollars to the YMCA, Columbia University, his own "Vanderbilt University" and "Vanderbilt Clinic" and gave a million dollars to tenement houses in New York. There was also one hundred-and-forty-six-acre estate built by another Vanderbilt brother, a summer home in Rhode Island, and then the philanthropy. William Vanderbilt spent money on yachts, thoroughbred horses, an expansive art collection, and ten mansions on Manhattan's fifth avenue. Vanderbilt's budgetary strategy was: frugal spending, so income was always higher than expenses, and savings were invested in making more income or saved as cold hard cash. When Commodore died in 1877, he reportedly had $100 million dollars in the bank, which would be worth $233 billion dollars today. At its peak, his company New York Central was the second-largest railroad in the US, with 11,000 miles of track across 11 states and two provinces in Canada. By 1967, he had control of all the railroads between New York and Buffalo. He was economical almost to extremes." This quote definitely came back to haunt him generations later.īy 1964, Commodore swapped his captain's hat for a conductor's hat and acquired controlling stakes in two New York-based railroads. A former clerk said, "He never had a debt and never bought anything on credit. Between the 1820s and 1850s, he built his own steamboat fleet, built his own ships, and even built his own canal to ferry passengers and mail from New York to California during the gold rush. ![]() He then saved the cash and would lend it out to earn interest or invest in hard capital like more boats or real estate. Commodore would use competitive pricing to undercut rivals so low they had to give in or buy him out. He was so successful that by 1817, he earned a government contract to ferry military supplies through New York Harbor in 1812. ![]() However, mobs of the undead variety, like zombies and skeleton archers or warriors, take damage. Mobs that spawn in the world, like spiders and other passive creatures, are healed by this potion. And both positive and negative potion effects can interact with monsters.įor example, a splash healing potion can heal or deal damage to monsters. It’s important to understand that each splash potion in Minecraft only applies one effect to its targets. Since one blaze rod only yields two blaze powder, players must farm Nether fortresses a lot to create multiple potions and eventually access the End. That’s one of the most challenging mobs in the game, especially for new or under-geared players.īlaze mobs are agile, shoot high-damage fireballs, and only have a default 50% drop rate for blaze rods. However, blaze rods only drop from killing Blazes in the Nether. But one of the most difficult components to farm for splash and regular potions is blaze powder.īlaze powder is made from blaze rods at the crafting bench. Then, each potion has its own list of ingredients, with farming methods ranging from easy to hard. You can obtain it from chests, Creepers, Witches, and Ghasts. Gathering gunpowder is easy enough to get. If you want to turn your potions into projectiles, you must do some mob farming. How to Get Ingredients for Splash Potions As a reference, the splash zone is an 8.25 x 8.25 x 4.25 block area expanding outwards from the point of impact. Wait for the brewing to finish, and add the splash potions to your inventory.Īlways aim the potion at a mob or player’s head to maximize the splash potion radius and duration. ![]() Add a maximum of three potion bottles in the UI’s lower row.Place your gunpowder in the upper middle slot of the brewing station UI.Add blaze powder in the fuel slot or the furthest upper left box.If you know how to brew a potion, you can probably figure out how to cook a splash potion based on the list of ingredients. Splash potions in Bedrock edition last 25% shorter than their regular counterparts. Distance to the splash center can affect how much of the effect (healing or damage) an affected entity takes or how long the effect lasts. However, the potion’s effect (potency) gets reduced if you miss your target. You can even create splash versions of uncraftable potions. You need three ingredients to make splash potions.Īlmost all potions can be brewed again into splash potions that apply an AoE debuff in a small radius. ![]() And although these potions can offer significant advantages in combat, they’re not hard to make, theoretically. But you can splash some on them to induce weakening effects of all kinds. Sure, you won’t find any mob in Minecraft that can willingly pick up a potion and drink it. Potions that apply debuffs to your character also work on mobs. But why would anyone drink a brew to intentionally make their character weaker? They wouldn’t.

![]() Alpha, Rutherford speculated, was a stream of positively charged helium ions.īy 1908, a year after moving to the University of Manchester in England, Rutherford was exploiting the alpha emission in a new experimental direction. Gamma appeared to be high-energy electromagnetic radiation. Beta seemed clearly to be fast-moving electrons (the subatomic, negatively charged particles that Thomson had identified in 1896 in studies of electrical effects in gases at very low pressures). By now recognizing that three major components could constitute these emissions-alpha, beta, and gamma-he was dedicated to identifying them. In the following year, Rutherford hypothesized that radioactive emission occurs at the instant that an atom changes its elemental identity. By 1902 they were convinced that radioactivity involved transmutations of atoms of one element into atoms of another element. He and the chemist Frederick Soddy undertook monumental studies of radioactivity, combining chemical analyses with investigations of ionization effects. In 1898, Rutherford was appointed professor of physics at McGill University in Montreal, Canada. Soon turning to investigations of radioactivity, which Antoine- Henri Becquerel (1852–1908) had just discovered, Rutherford applied the technique of quantitatively assessing ionization effects in air surrounding radioactive substances-he was able to identify two components of emissions from radioactive substances: alpha was easily absorbed by a thin foil, while beta penetrated the foil. He and Thomson studied the ability of X-rays (recently discovered by the German Wilhelm Conrad Roentgen) to "ionize" gases into positively and negatively charged particles and thus increase the ability of the gases to conduct electricity. degree at Canterbury College, Christchurch, New Zealand. Born in New Zealand, Rutherford came to the Cavendish Laboratory at Cambridge University, England, in 1896 to study with Joseph John Thomson shortly after earning the M.A. This conclusion led to the theory that electrons exist in energy levels around the positive nucleus and have their own distinct properties in each of their energy levels.RUTHERFORD, ERNEST (1871–1937), New Zealand-born scientist.Įrnest Rutherford's experimental work was essential to early-twentieth-century revolutionary developments in atomic physics. This theory was adopted by Niels Bohr in 1913 who theorised that electrons could orbit the nucleus in a circular orbits and that the distance of the electron to the nucleus was fixed unless it moved between energy levels with the absorption or emission of light. Max Planck and Albert Einstein in the field of physics postulated that light energy can be absorbed and emitted as quanta. It was not until the earlier 20th Century that the scientific community arrived at the modern day atomic model. Now the atomic model had a central particle and electrons around it, reversing he plum pudding model of Thomson. He named this new fundamental particle as a proton. Rutherford conducted a number of experiments with hydrogen nuclei and nitrogen in air using alpha particles and after a number of theories concluded that the hydrogen atom made up other atoms. Rutherford further followed this up in 1917 when he proved that a hydrogen nucleus (1 proton) is present in other nuclei of different elements most notably nitrogen gas in the air. ![]() The vitreous in the deep fovea may act as a third lens, increasing magnification to the optic system. However, the precise function of each fovea is uncertain. According to researchers, their eyes can operate like telephoto lenses by magnifying objects in the center of their fields of vision thanks to their deep fovea. From Duan et al, 2013.Īccording to the anatomy of the foveae, the deep fovea (nasal fovea) has the highest acuity, especially useful for viewing objects from a long distance. Line of sight (LOS) for deep fovea vs shallow fovea. The deep fovea’s (nasal fovea) line of sight is forward and approximately 45 degrees to the right or left of the head axis, while the shallow fovea’s line of sight is forward but approximately 15 degrees to the right or left of the head axis. ![]() In contrast to the deep convex pit found in hawks and eagles, the human fovea is like a little shell or bowl. ![]() Raptors, including falcons, hawks, and eagles, have two retinal regions specialized for acute vision in each eye: the deep fovea and the shallow fovea. This remarkable visual acuity is made possible by the tubular shape of the eye, a huge pupil, retinas with cones, and a significantly deeper fovea, a structure in the back of the eye that is rich in cones. Imagine being able to spot a pizza from 2 miles away! And pizzas don’t normally hide camouflaged under bushes! Why Do Eagles Have Such Amazing Visual Acuity? An eagle can see an animal the size of a rabbit about 2 miles (3.2 km) away.Ī rabbit is roughly the size of a medium pizza. Eagles have evolved the ability to quickly change the shape of their cornea and lens to focus on both near and far objects at high speed.Eagles have a 340-degree field of vision with peripheral eyesight superior to humans.An eagle must turn its head to look to the side and can swivel its head nearly 270 degrees.Eagle eyes fill their entire sockets and are fixed in place.Sometimes a bird’s eyes are heavier than its entire brain! Eagle eyes are huge the eyes of a 10-pound (4.5-kg) eagle may be as large as those of a human weighing 200 pounds (90.7 kg). ![]() An eagle’s eye has two focal points, or fovea, one pointed forward and the other to the side.Eagle eyes have one million cone cells per mm2 compared to 200,000 per mm2 for human eyes.Imagine spotting a medium pizza that far away! Eagles can spot a fish or rabbit from 2 miles away.Eagles have a remarkable 20/5 or 20/4 visual acuity, which means that they can see things from 20 feet away that we humans would only see from 5 feet away.Eagles and hawks have the best vision of any vertebrate species.When an eagle swoops down on its prey at 100 mph, the muscles in its eyes continuously adapt the curvature of the eyeballs to maintain a crisp focus and precise depth perception. Eagle eyes have over one million cone cells per mm2 compared to human eyes with 200,000 cone cells per mm2. The remarkable vision of an eagle is the result of key adaptations in its eyes. A soaring eagle can spot a rabbit from 2 miles (3.2 km) away. It is four to eight times better than ours. Eagles and other birds of prey have the best visual acuity of any group of animals. |
