Joe Rogan himself recently said he has put on weight – and that he carries extra weight on his torso as well as his face. “Now I’m not trying to say it’s bad…this is simply what happens with chronic growth hormone abuse and this is what you see – that traditional acromegaly look or Palumboism look, you have the continued progression of bone growth, collagen deposition, connective tissue growth, and this is all a result of chronic GH abuse,” he concluded. He does not believe this is the case with Rogan. The YouTuber added that some bodybuilders appear to have significant bloating as a result of digestive issues, but that this is typically reversible via diet mainpulation. This is the traditional cause of Palumboism and while many would say why the hell would JR have insulin resistance, it probably doesn’t have to do with his diet necessarily, it probably has more to do with his chronic use of growth hormones.” The more nerve damage the limbs get, the more atrophied the look, and as well, as more distended the stomach will look. He said: “As insulin resistance starts to set in, their chronically high blood sugar levels can lead to nerve damage in the limbs. YouTuber More Plates More Dates made a video Rogan’s appearance, in which he discussed the connection. The cardiologist isn’t the only one linking bubble guts with HGH. He said: “There has been amongst the bodybuilding community and those that critique the bodybuilding community a theory that the excess GH, the excess other steroid building properties and agents that are used may cause insulin resistance, may involve and deteriorate the normal musculature and nerve supply to some of the abdominal muscles around the lateral side of the belly and allow the belly to get this very unusual but distorted shape – this roid gut, this bubble gut, this Palumboism.” Distended Kahn, HGH is important for children who have a growth hormone deficiency – but it does cause insulin resistance. “ has said many times that he’s taken testosterone for over a decade…and he’s said in the past that he’s taking growth hormone, whether he is now or not I don’t know, he hasn’t mentioned it recently…But there has been an explosion of discussion on Reddit and other channels that Joe Rogan is suffering from the same thing he’s pointed out in bodybuilders as being sort of an unattractive consequence of abusing agents that shouldn’t be abused.”Īccording to Dr. “This particular video and the side view where his abdomen looked – not just a bit protuberant, but perhaps having this bubble gut appearance of growth hormone and insulin users in the serious professional weight-lifting world, has raised a question,” said Dr. Joel Kahn spoke to PBN‘s Klaus Mitchell about the prevalence of the ‘bubble gut’ phenomenon (aka Palumboism) in the bodybuilding community – and the potential causes. In the video, Rogan – who has openly spoken about taking Human Growth Hormone (HGH) and testosterone in the past – appears to have a dramatically different physique than in the past – with a noticeably protruding torso. The leading podcaster and comedian’s physique has been the subject of much scrutiny since he revealed all during a weigh-in last October, with a video of the event being circulated widely online. A leading cardiologist has suggested that Joe Rogan‘s ‘bubble gut’ could be a result of insulin resistance in this exclusive new Plant Based News video.

How many times do we really need the '(insert character names here) saves Christmas' story to be told? Ice Age sort of did the same thing, but they did so in a way that put a clever twist on the origin of the holiday. For pure Madagascar fun, this is all well and good, but it's completely unoriginal. The lion, zebra, giraffe and hippo come up with a plan to deliver the presents themselves so they might save the world from a fate of broken hearted children. This gives the jolly man with the rosy cheeks a serious case of amnesia, which comes with the potential cost of having to cancel Christmas. Santa shows up to deliver coal to Julien again, but he, too, is blasted from the sky. Of course, this was only Santa Claus punishing King Julien for being on the naughty list, but as we already know, his ignorance knows no bounds. Our Madagascar friends learn that this 'goblin' comes once a year and showers the lemur population with coal. Predictably, Alex, Marty, Gloria and Melman are hoping to make their way back to New York City in time for Christmas, but a series of complications thwart their plan - King Julien mistakes the gang's makeshift hot air balloon as the 'red night goblin' and blasts them out of the sky. I'm a big fan of the Madagascar franchise, believing each successive film to be better than the last, but this Christmas special just didn't do anything for me. Moving on to Merry Madagascar is where the sleigh begins to fall off its rails, though. Fun in the Shrek-verse continues with Donkey's Christmas-tacular, as the entire gang puts a comical spin on the most notable holiday tunes of all time. It does a wonderful job of conveying the fact that you don't need a bunch of fancy ornaments or decorations to have a good time, because what's truly important is spending time with your friends and family. Things start off promising enough with Shrek the Halls, which is a terrific standalone effort that embraces the ideals of the holiday, as opposed to the superficial aspects that tend to go along with it. There are definitely some redeemable qualities to this collection. A Christmas special should invoke the same kind of feeling you get when you see a majestically decorated tree for the first time all year, but in this case, it felt more akin to receiving an ugly Christmas sweater.ĭon't get me wrong, it's not all bad. Most of these shorts have been solely designed to showcase the beloved characters of the studio, which makes the oh so important heart behind the holidays little more than an afterthought. With that being said, it feels like there's something missing from the overall experience provided in Dreamworks Holiday Classics, and the reason for that is simple - Dreamworks tried to replicate the success of their Halloween offerings in very much the same way, which was to give us the proper visual cues and hope that made the final product feel Christmassy enough. Now, although Christmas is also often associated with parties and various other fun gatherings, it's more about warmth, compassion, giving unselfishly, and spending time with your family and friends. Halloween is just a lot of silly fun that can be enjoyed by children and adults alike. All you really need for a good Halloween special is a story that takes place on all hallows eve, featuring the appropriate colors, costumes, ghouls, and atmosphere. In all fairness, that's not exactly hard to do, right? Halloween means so many things to so many people - Some associate the holiday with thrills and chills, some with the prospect of obtaining candy, and others just like to dress up and party. To say it's a bold move for Dreamworks to think they can actually compete in this market is an understatement if there ever was one, and predictably, the Dreamworks Holiday Classics collection falls short many expectations.įirst, let me reiterate why the Halloween release worked as well as it did - It actually nailed the spirit of Halloween. You can't even talk about Christmas specials without thinking of Charlie Brown's barren tree, a stop-motion animated reindeer with a red nose that glows, or the joyous snowman that proudly announces his birth upon coming to life. Of course, it had an advantage, as there really aren't too many worthwhile Halloween specials on the market, but Christmas? The holiday brought forth by the sight of candy canes and decorative trees, as well as the smell of pine and gingerbread, has more than a healthy handful of classics that stand proudly beside it. Just a few short months ago, Dreamworks put their stamp on the holiday home video market with a collection of Halloween shorts, and there's no question that it was a delightful treat. *Click on ALL images in this review for full 1080p screenshots Log in to your Netflix account - either online or on the mobile app. If you don't want to pay extra for an additional household, or have decided you can no longer justify the cost of a Netflix subscription yourself, it's easy to cancel. Read our guide to Netflix for more information on how Households work in Netflix, the options available, and pricing. On Premium, you also get Ultra HD on any additional households. For example, it costs the same amount to have an extra household on a Standard or Premium plan that includes advert-free streaming as it does to take out a 'Standard with adverts' plan separately. Weigh up your options carefully if you want to keep Netflix. The Standard plan comes with one additional member by default, and the Premium plan with two. Buy an extra member: alternatively, households on Netflix's Standard or Premium plans can purchase additional members - someone who doesn't live in the same household - for £4.99.This would essentially mean the person you're sharing your account with setting up their own Netflix subscription, and inheriting the shared account. Transfer a profile: this allows you to transfer a profile, including recommendations, viewing history, My List, saved games and settings to a new membership.Netflix has introduced two options for those who share accounts with different households.

The move is essentially an attempt to ensure that those who watch Netflix, are paying for their subscription.ĭespite this, it is expected that many will seek to cancel their Netflix account rather than pay extra - 'cancel Netflix account' was a trending search term shortly after the announcement was made. Globally, it's estimated Netflix is being shared with over 100 million additional households. It is estimated that around 3.75 million subscribers - or a quarter of Netflix's UK subscribers, share their password, despite Netflix clearly stating that an account is 'for you and the people you live with'. Why is Netflix charging me to share accounts? See how Netflix ranks in our guide to the best and worst TV streaming services. Read on to find out more about your options. Users can choose to buy an 'extra member', transfer accounts - or cancel their membership. It follows a similar crackdown in other countries, including New Zealand, Spain, Portugal and Canada. Streaming giant Netflix has begun emailing UK users who share their account with different households to inform them that an additional charge will be required to continue doing so. Edge Storage: microSD, microSDHC, microSDXC.Video Codecs: H.264 Baseline, Main, High Motion JPEG.Axis D2050-VE Radar Detector Quick Specs: The radar detector is IP66, IK10, and NEMA 4X rated with an operating temperature range of -40☏ to 140☏. Store the evidence through the network using an NVR or NAS solution, or locally using a microSD, microSDHC, or microSDXC card. It can also trigger recording, so your video surveillance system is more resource-efficient. This means you get protection at any time of day or night, no matter the environmental conditions.īecause Axis D2050-VE is an IP device, it can work with compatible PTZ IP cameras to provide auto-tracking. You can set it to filter based on distance and size of object, preventing false alarms. It can detect position down to a meter, as well as angle of movement and velocity. D2050-VE has a 50m (164ft) range with a 120° horizontal field of detection. Axis D2050-VE is an IP radar detector, connecting with your IP network, and is compatible with a broad range of VMS platforms. The recommended replacement is the Axis D2110-VE.Īxis D2050-VE is a network-enabled and vandal-resistant security solution that uses radar to detect trespassers and enable actions in all weather and lighting conditions. The other platforms have radars with smaller scan regions, allowing them to revisit the targets at a higher rate.The Axis D2050-VE has been phased out and is no longer available for purchase. The small number of detections from this platform is due to its radar's 360 mechanical scan, which limits how frequently its beam can revisit a target in the scenario. The blue airborne radar with the rotating array generates the fewest number of detections (only 4 detections for these two targets), but these detections are the most precise (smallest ellipses). In this case, the platform's radar reports detections at 0 degrees with an uncertainty in elevation corresponding to the elevation field of view. This is because the linear arrays on this platform are unable to provide estimates in elevation. The ellipsoids have small axes in the range and azimuth directions but have very large axes along the elevation direction. Notice the large uncertainty in elevation of the red detections generating from the airborne platform (Platform 2) that uses two linear arrays. Set the UpdateRate to 0 to let trackingScenario determine the next update time. The trackingScenario can advance at a fixed time interval or automatically determine the next update time. For each step forward in the scenario, detections are generated from each platform. The following loop advances the platform and target positions until the end of the scenario.

The work done by the force f acting on the differential area due to the deformation of the differential beam length dx is as follows: The deformation of a differential beam length dx at a distance x from the left-end support is as follows: The stress due to the external loads P1 and P2 on the beam is written as follows: The force acting on the differential area due to the virtual unit load is written as follows: M = internal virtual moment at the section at a distance x e from the left-end support due to the virtual unit load. The stress acting on the differential cross-sectional area dA at a distance x from the left-end support due to a virtual unit load is as follows: First, removing the loads P and W and applying a virtual unit load P v = 1 will cause elementary forces and deformations to develop in the bar, and a small deflection to occur at C, as follows: Fig. The deflection at point C due to the applied external loads is required. To develop the equations for the computation of deflection of beams and frames using the virtual work principles, consider the beam loaded as shown in Figure 8.2a. Θ = external rotational displacement caused by real loads.Ĩ.1.1 Virtual Work Formulation for the Deflection and Slope of Beams and Frames Similarly, to obtain the slope at a point on a structure, apply a unit virtual moment M v at the specified point where the slope is desired, and apply the following equation derived via the principle of conservation of energy: ∆ = external displacement caused by real loads.ĭS = internal deformation caused by real loads. The work done by the virtual forces are as follows:Īpplying the principle of conservation of energy by equating equation 8.1 and equation 8.2 suggests the following: Upon placement of the real load, the point of application of the virtual load also displaces by ∆, and the applied unit load performs work by traveling the distance ∆. Then, placing the real external loads P 1, P 2, and M on the same body will cause an internal deformation, dS, and an external deflection of point Q to Q’ by an amount ∆. First, applying a virtual or fictitious unit load P v = 1 at a point Q, where the deflection parallel to the applied load is desired, will create an internal virtual or imaginary load f and will cause point Q to displace by a certain small amount. To illustrate the principle of virtual work, consider the deformable body shown in Figure 8.1. This method was developed in 1717 by John Bernoulli. The virtual work method, also referred to as the method of virtual force or unit-load method, uses the law of conservation of energy to obtain the deflection and slope at a point in a structure. Also show stress-time variation curve (sinusoidal).\)ĭeflections of Structures: Work-Energy Methods If the mean stress sigma-m = 30 MPa, using Soderberg Equation determine the maximum and minimum values of the end load.
