Does a duck billed platypus have a stomach10/11/2023 ![]() It was believed that the male puggle platypus produces venom for protection against the wild. On their hind legs, there’s a stinger that secretes venom. One of the interesting facts about the male “puggle” is that they are venomous. At that time, the baby platypus is ready to swim as their mother taught them everything in the initial four months of its life.Īs adults, platypuses are without teeth, so they use a little rock or gravel in order to assist them in chewing the food properly. When they become four months old, they lose all their teeth and never get them back. Like other creatures hatched from an egg, the baby platypus already has teeth (called egg teeth) at the time of hatching, allowing them to break the egg shell and enjoy the new life. The female platypus digs a tunnel-like portion in the soil, and here she lays her eggs and sleeps on top of them to ensure they get enough incubation time. #1 Baby Platypus Have Temporary Teeth At BirthĪs platypi are mammals hatched from the egg, the process begins when the mature female platypus is ready to lay an egg. Below, we have explained the most interesting facts about the adorable baby platypus. They possess various features which make this creature especially unique. When a platypus grows into an adult, it eats dragonflies, water beetles, and other aquatic invertebrates. The nursery-age platypus eats insects, and the juvenile platypus’s diets include shrimp, crayfish, and other tiny fish. Interesting!īaby platypuses eat various things. They also suck the milk from the mother’s hair. Instead, the mother platypus sweat out the milk, so the milk pools into the grooves, which the baby platypus then drinks. But one fantastic thing about them is that the mother platypus doesn’t have teats. Platypus Babies FoodĪs you know, platypuses are mammals, so like all other mammals, they feed their young with milk. They hide during the day and find food at night, and only occasionally are they active during the day. After a few months, they make their first attempt at swimming and thus start spending some time in the water.īaby platypus is found only near Tasmania and in eastern Australia. Therefore puggle platypuses live in a tunnel dug by their mothers, where they hatch from the eggs. Baby Platypus Habitatīaby platypuses cannot find food for themselves and depend on their mothers. At the age of 18 months, they mature sexually and become fully grown. Therefore they require significant care as they are completely dependent on their mothers. Size Of Puggle PlatypusĪt the time of birth, the baby platypus is only around 3 cm in size. At the time of hatching, the puggle platypus is only the size of a nickel.Īs they can not swim at this stage, their mother cares for them for about three to four months. When the puggle platypus is born, it weighs only about 50 to 80 grams as it is very fragile and small. anatinus is the platypus species which is also its scientific name. Ornithorhynchidae is the platypus’ family. Order:Īs platypus lay eggs, therefore, they are included in the order Monotremata. This is so because their young feed on their mother’s milk. Mammalia is the class in which platypuses are enlisted. Platypus belongs to the kingdom Animalia. Scientific Classificationīelow is the scientific classification of platypus. Keep reading!

Nasa kepler10/11/2023 ![]() These posters show places in our solar system (and beyond) that likewise haven't been photographed on a human scale yet - or in the case of the exoplanets might never be, at least not for a long time. They were created at a time when color photography was not very advanced, in order to capture the beauty of the national parks from a human perspective. Joby Harris, illustrator: The old WPA posters did a really great job delivering a feeling about a far-off destination. There's a nostalgia for that era that just feels good. ![]() The JPL director has called our people "architects of the future."Īs for the style, we gravitated to the style of the old posters the WPA created for the national parks. The point was to share a sense of things on the edge of possibility that are closely tied to the work our people are doing today. They suggested it might be wonderful to give a similar treatment to the amazing destinations in our solar system that JPL is currently exploring as part of NASA. (The NASA program that focuses on finding and studying exoplanets is managed by JPL.) Later, the director of JPL was on vacation at the Grand Canyon with his wife, and they saw a similarly styled poster that reminded them of the exoplanet posters. Each poster went through a number of concepts and revisions, and each was made better with feedback from the JPL experts.ĭavid Delgado, creative strategy: The posters began as a series about exoplanets - planets orbiting other stars - to celebrate NASA's study of them. Background: A creative team of visual strategists at JPL, known as " The Studio," created the poster series, which is titled "Visions of the Future." Nine artists, designers, and illustrators were involved in designing the 14 posters, which are the result of many brainstorming sessions with JPL scientists, engineers, and expert communicators. 3.5 warblade maneuvers list10/11/2023 Readying maneuvers makes any expended maneuvers available again, and takes five minutes of exercise, meditation, etc.Įach of the martial adept classes also gets access to a special recovery mechanism. If I use one, is it gone until the next day? Until the next encounter? (But yes, if you were a 1st level warblade, you'd have three known and three readied.) So you would have to pick three of your five known maneuvers to have ready. Does that mean that I get to go into an encounter and use any maneuver I have whenever I want?Īs a 3rd level warblade, the table indicates that you have 5 maneuvers known and 3 readied. ![]() The chart says I can have three known and three ready. Note that for the purposes of meeting prerequisites, stances also count as maneuvers.Īlso, at certain levels (starting at level 4 for warblades) you can swap out maneuvers for other maneuvers - when you do this, you can count the maneuver you're swapping out towards meeting a prerequisite for the maneuver you're swapping to. ![]() Some maneuvers and stances have prerequisites - usually, having a certain number of maneuvers in the same school. In the description of each maneuver and stance, it says what martial discipline it belongs to just under the name of the maneuver, as well as what classes can learn it in the Level field. Warblades can select maneuvers and stances from the following martial disciplines: Diamond Mind, Iron Heart, Stone Dragon, Tiger Claw, White Raven. So to learn a 3rd level stance or maneuver, your initiator level needs to be (3 × 2) - 1 = 5.Īs a 3rd level warblade, this means you can have four 1st-level maneuvers, one 2nd-level maneuver, and one 1st-level stance.Įach class is restricted in what stances and maneuvers it can choose based on what are called martial disciplines. In order to learn a maneuver, your initiator level needs to be (maneuver level × 2) - 1. In order to select a maneuver of a given maneuver level, you must have a sufficiently high initiator level. If you aren't multiclassed, initiator level is simple. This can get a little confusing, because there's the maneuver level, your initiator level, and your class level which are all related to one another but aren't exactly the same. There are three basic kinds of requirement:Įach maneuver or stance has a level. You have to meet the requirements for the maneuvers/stances you select, at the time that you select it. You learn maneuvers and stances according to the progression described in the warblade table and in the warblade section.

The same package is available in red for Evening Black or Whisper White T-Birds. If you order this package, cars that are Inspiration Yellow, Torch Red or Thunderbird Blue will get the above-noted interior pieces in the same color. While the standard interior color is black, there's an interesting option package in which the seats, lower instrument panel, steering-wheel top and shift knob match or contrast the five available exterior colors. ![]() The leather seat trim has what Ford calls a "Thunderbird tuck and roll," and the driver seat has six-way power adjustment and adjustable lumbar support. Moving to the car's intimate two-seat cabin, you'll find many of the buttons and switches, as well as the instrument cluster, are lifted directly from the Lincoln LS - though instrumentation does utilize attractive white-faced gauges. Looking for maximum traction in all kinds of weather? Spring for the optional traction-control system. All 'Birds come with ABS and four-wheel disc brakes. Cast aluminum 17-inch wheels are also standard in a 21-spoke design, which, frankly, we like better than the optional seven-spoke chrome wheel. The control arms are made of aircraft-grade forged or cast aluminum to reduce weight. The LS' five-speed automatic transmission is the only gearbox available at this point.įord's new two-seater rides on a full independent suspension that uses a short-long arm (SLA) design at the front and rear. In feathered trim, the engine also produces the same 252 horsepower at 6,100 rpm and 267 foot-pounds of torque at 4,300 rpm. Riding on the same platform as the Lincoln LS, the 'Bird uses the same 3.9-liter DOHC V8, as well. Now a Ford two-seater is back, and it will be a sight to see on the road. That's right, the introduction of the '55 T-Bird combined with the sale of only 700 '55 Vettes nearly put the kibosh on Chevy's two-seater. Looking back on the various types of cars the Thunderbird name has been used on, it's amazing to think that this is the model that helped almost kill off the Corvette. After more than 40 years, a proper two-seat Thunderbird roadster has returned. Coweta fayette emc outage line10/11/2023 Georgia’s cooperatives lead the nation among electric co-ops for solar deployment, and in the past six years have grown their solar portfolio by 8,000 percent. Silicon Ranch pioneered utility-scale solar in Georgia and remains a market leader, with nearly two gigawatts across the state. ![]() The 252 MWAC portfolio further expands the industry-leading partnership between Silicon Ranch and Green Power EMC. ![]() “By combining renewable energy generation with regenerative agriculture practices, this innovative solar portfolio with Silicon Ranch will benefit the people, land, environment, and local economies in Jeff Davis, Lee, and Montgomery Counties.” “Georgia’s cooperatives continue to grow their renewable energy portfolio with collaborative, low-cost solar power projects that deliver value to their members and the rural communities they locate in, not only through the clean energy they provide, but also through the manner in which it is generated,” said Green Power EMC President Jeff Pratt. This unique procurement model allows participating cooperatives to capture value through economies of scale and source low-cost renewable power to benefit the members and communities they serve. Green Power EMC will purchase all the energy and environmental attributes generated by the facilities on behalf of its member cooperatives. The company will also own, operate, and maintain the arrays for the long-term, a disciplined approach Silicon Ranch takes with every project it develops. Silicon Ranch is funding the three utility-scale solar facilities and plans to build them in stages over the next three years. The total capacity will be generated across three locations in southern Georgia and will produce enough low-cost, renewable power to help serve more than 44,000 EMC households annually. Green Power EMC, the renewable energy supplier for 38 Georgia Electric Membership Corporations (EMCs), and Silicon Ranch, one of the nation’s largest independent solar power producers, announced an agreement to bring an additional 252 megawatts (MWAC) of solar energy online to serve 16 subscribing cooperatives from across Georgia. Green Power EMC and Silicon Ranch Announce 252-Megawatt Solar Portfolio in Georgia ![]() “They are bringing to market bleeding-edge technology and solving extremely hard problems in a market that is struggling to find labor. “With logistics and fulfillment experience at Amazon, iHerb and other retail companies, I've worked with a lot of technology teams, and the Nimble team is the most impressive robotics team I've ever worked with,” said Jonathan Styles, director of continuous improvement-lean at iHerb. To date, we have 100% customer retention and 100% repeat customers.” We let the robots speak for, and sell, themselves. “I think this is a testament to the high demand for what we’re building and to our product and how well it works. “We haven’t done any marketing and surprisingly we don’t have any dedicated sales reps, yet we’ve deployed a large number of robots,” said Kalouche. Nimble said it is working with many of the world's largest and best-known brands including Best Buy, Victoria’s Secret, Puma, NFI/CalCartage, and Weee! It added that its robots are picking in warehouse applications developed by systems integrators such as AutoStore, OPEX, Bastian, Swisslog, TGW, and Kuecker Pulse Integration (KPI). Source: Business Wire Big brands turn to picking robots Nimble Robotics supports e-commerce order fulfillment. Just like with self-driving cars, more data means higher capability and reliability which further drives customer retention and happiness.” “More robots deployed means more proprietary data being collected. “To my knowledge, we’ve now deployed the world’s largest fleet of e-commerce ASRS picking robots,” he stated. This has been a significant competitive advantage allowing us to quickly scale.” ![]() “When I say, ‘One day, $0, zero code changes,’ it sounds too good to be true, but our customers will vouch for us. “A full production integration can all be done in one day using Nimble’s AI Integration tool,” said Kalouche. The AI interprets the already existing human operator interfaces to determine what items to pick and where to pack them.” ![]() Our AI-based integration requires no changes to the warehouse software whatsoever. “Our technology has been proven to be reliable to 99.9% accuracy in production, but what’s often the most impressive and exciting product feature, in the eyes of our customers, is the way in which we seamlessly integrate our robots,” he added. “Our AI learns what grippers work best on different objects and automatically switches its gripper to properly pick, pack, and handle each object.” “Our robots use a variety of different grippers and supervised autonomy to reliably handle nearly any object or product that fits into a bin,” said Kalouche. The company said its robots have picked more than 15 million objects across 500,000 unique products, ranging from cosmetics and consumer electronics to apparel, from daily essentials to holiday gift favorites. It added that it expects existing and new contracts to grow the fleet with over 200 more robots in 2022. Nimble said it has deployed fleets of robots within warehouse environments across the U.S. Nimble touts flexibility, ease of integration ![]() Nimble said its offering uniquely solves these two challenges. Integration efforts frequently take up to a year, cost hundreds of thousands of dollars, and require thousands of software changes to the warehouse management system ( WMS). In addition, integration of technology into warehouse ecosystems is a notoriously painful process, Nimble said. Having robots that can reliably handle all of this variability has been considered by many to be impossible, said Nimble. Each of those products are different sizes, shapes, weights, textures, stiffnesses, and fragility. E-commerce fulfillment centers hold millions of different products, said the company. Over the past few years, said Nimble, two challenges have stifled the adoption of pick-and-pack robots: reliability and technology integration challenges. Our robots are being used to augment the human workforce to help fill that void.” “These opposing trends are creating historic labor shortages and a growing labor supply void. “ E-commerce continues to grow rapidly, but the available warehouse labor force is actually declining,” said Simon Kalouche, founder and CEO of Nimble Robotics. The San Francisco-based startup claimed that its robots use artificial intelligence to “pick, pack, and fulfill online orders to enable the fastest, most affordable, and most sustainable on-demand e-commerce fulfillment.” this week said that its robots have picked and packed hundreds of thousands of customer orders on a daily basis. Negative plus negative positive or negative10/10/2023 ![]() During the induction phase, patients received the TKI plus vincristine and dexamethasone in three 28-day cycles, after which the primary end point was assessed, then they proceeded to the consolidation phase which consisted of the TKI plus methotrexate and cytarabine in six 28-day cycles, followed by maintenance therapy with the TKI plus vincristine and prednisone in eleven 28-day cycles, and finally treatment with TKI monotherapy until the completion of the study. Patients were randomly assigned 2:1 to reduced-intensity chemotherapy in combination with ponatinib 30 mg once daily with dose reduction to 15 mg once daily (n = 164) after MRD-negative CR in the induction phase or reduced intensity chemotherapy with imatinib at a starting dose of 600 mg once daily (n = 81).

Lead's high density, low melting point, ductility and relative inertness to oxidation make it useful. In 2014, the annual global production of lead was about ten million tonnes, over half of which was from recycling. ![]() Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial Revolution. Interest in silver helped initiate widespread extraction and use of lead in ancient Rome. Galena is a principal ore of lead which often bears silver. Since lead is easily extracted from its ores, prehistoric people in the Near East were aware of it. Like the lighter members of the group, lead tends to bond with itself it can form chains and polyhedral structures. Exceptions are mostly limited to organolead compounds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Its weak metallic character is illustrated by its amphoteric nature lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Lead is a relatively unreactive post-transition metal. Lead is toxic, even in small amounts, especially to children. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. It tarnishes to a dull gray color when exposed to air. When freshly cut, lead is a shiny gray with a hint of blue. ![]() Lead is soft and malleable, and also has a relatively low melting point. It is a heavy metal that is denser than most common materials. Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. AuthorWrite something about yourself.
