Alzheimer’s diseaseĪ study published in the journal Neurobiology of Aging concluded that acetyl-L-carnitine may help people with Alzheimer’s disease. The authors found that patients with peripheral arterial disease were able to walk comfortably for longer times and distances after using PLC. The pain usually occurs in the feet, calves, thighs, hips or buttocks, depending on where the artery damage or narrowing occurs. It tends to affect the blood vessels in the legs, but it can affect the arms too. Intermittent claudication can lead to pain when walking or running, because damage or narrowing of an artery leads to poor blood supply. Intermittent claudicationįindings published in the journal Thrombosis Research looked at the efficacy, safety and tolerability of propionyl-L-carnitine (PLC) given to patients with a condition known as intermittent claudication. They believe carnitine may reduce symptoms of fatigue in patients with chronic diseases. “Combinations of these supplements can reduce significantly the fatigue and other symptoms associated with chronic disease and can naturally restore mitochondrial function, even in long-term patients with intractable fatigue.” Research published in Alternative Therapies In Health And Medicine suggests that combinations of supplements, including carnitine, might help improve mitochondrial function. Most chronic diseases lead to a loss of mitochondrial function that can result in fatigue and other symptoms. Fatigue and other symptoms of chronic disease ![]() Black, cell and molecular physiologist at the Vascular Biology Center at the Medical College of Georgia at Georgia Regents University. However, it did not lead to a fall in the development of heart failure or a repeat myocardial infarction (MI).Ĭarnitine may also normalize the type of blood vessel dysfunction that happens with congenital heart defects, according to Dr. In 2013, a review and meta-analysis linked L-carnitine with a 27 percent reduction in all-cause mortality, and notably, a 65 percent drop in ventricular arrhythmias and a 40 percent fall in the development of angina. The findings were published in Drugs Under Experimental and Clinical Research. Angina and heart problemsįor some time, studies have suggested that carnitine may help treat the symptoms of angina if used alongside conventional treatment. One study found that ALC is as effective as a conventional treatment, methylcobalamin (MC), in treating diabetic peripheral neuropathy.Īnother investigation, involving 19 patients, found that ALC did not change the frequency or severity of the condition. One review study has stated that acetyl-L-carnitine (ALC) had a moderate effect on reducing pain, but the evidence is still conflicting, and more research is needed. Health conditions that carnitine may be used to treat include heart failure or heart attack, angina, and diabetic neuropathy. People who lack carnitine may need to take supplements or eat specially enriched foods.Ĭarnitine is said to have many therapeutic properties that may be useful in treating a range of conditions and illnesses.Īs an antioxidant, carnitine fights off harmful free radicals, which cause severe damage to cells.

Primary systemic carnitine deficiency can happen when the protein that is responsible for bringing carnitine into cells undergoes a genetic change. However, genetic or medical reasons can cause some people produce too little. The liver and kidney usually produce enough carnitine in the human body, so topping up with food or supplements is not necessary.

After it finishes, double-click the file and enjoy watching! Solutions to Fix Handbrake Not Rip DVDīut what would you do when Handbrake did not successfully rip the DVD? DVD ripping is commonly challenging, even for Handbrake. The processing will take some time, and you can keep track of the progress bar at the bottom part of the interface. Click the "Start Encode" button from the upper menu. Step 4.Once done, it is time to rip the DVD. Remember that the higher quality you choose, the bigger the storage space consumption will be. ![]() Next, edit the quality preset settings to adjust the picture, video, and audio output. Step 3.Click the "Browse" button under "Destination" to choose the local folder to store the video. Wait for the scanning process, then head to the "Title" menu and choose the video or title to rip. Launch the Handbrake app and select the DVD drive from the sidebar. Step 2.After the first step, you will need to rip the disk. It is usually in the "C:Program FilesHandbrake" if you use the default installation settings. Then, copy the DLL file to the Handbrake app folder. Download the version according to the Windows version you have. Step 1.The first thing to do is install libdvdcss. As long as you want to watch movies on your computer, this method will work out for you. Fortunately, Handbrake can still read copy-protected DVDs using libdvdcss– a free DVD playback library. The video transcoder works with DVDs that are not copyright-protected otherwise, DVDs bought from an official store are difficult to decrypt.

Swapped the disc out and the new one converted with no problem.Guide List How to Use HandBrake Rip-Protected DVD Solutions to Fix HandBrake Not Rip DVD Bonus Tip for DVD Playback FAQs about HandBrake DVD Ripping How to Use HandBrake Rip-Protected DVD Eventually, I narrowed it down the disc itself. I had one that looked pristine (no scratches), appeared to rip just fine but did the same thing. If you see something at the spot, it's the ripping that is probably at fault (or the disc itself is bad). Do this on your computer rather than the DVD in a DVD player as the DVD player may be better at handling error correction. Maybe the spot is the part that makes HB give up. Drop the needle beyond the sanded area and it will play fine. Drop the needle at the beginning and the album will play fine. You could take some sandpaper to the middle of the album and pretty much destroy the grooves leaving those before and after in fine shape. You can't skip ahead beyond the spot and then claim the movie plays just fine. However, you need to let it play the cut-off spot. Does it play through the point where it cuts off if you HB it? If it does, HB should be able to handle it. After ripping a DVD try playing the ripped file on your computer. You'll never get a consensus.ĭouble layer DVDs are usually OK. Else, you get a bunch of opinions from people with all kinds of different technology, in different viewing environments, etc. If you have someone with you, ask them to randomly select each file so you don't know which encode you're judging (a blind test). Then, go to your own set and play them back and see which one you like the best. The best way to find the right setting is to start with a preset like TV3, encode a chapter or two, then slide the RF slider down a notch and encode the same chapter or two. They know they have 50GB-100GB of space on the BD so they may choose to use the space than optimize the encoding. People often perceive this is going to be noticeable detail but the key is thinking about the Studio encoding. ![]() If you re-encode, it will throw out some detail to cut that h.264 file down to smaller sizes. Typically, the HB user will eject much of that so that you end up with just a Dolby Digital and Stereo audio track, plus an h.264 video. Other parts of why BD files have much bigger file sizes is that they are using much more modern audio encoding (bigger audio files than Dolby Digital), many languages, and many audio tracks (such as several different english audio tracks, director narration, etc). For BD, much of the time the BD is already using h.264 so you can use software to simply re-wrap without re-encoding it to maintain a duplication of picture (and raw file size). especially for DVDs which are using a much dated standard. The dramatic reduction in file size is mostly driven by more efficient encoding. ![]() The handbrake team themselves suggests RF=19 for quality hounds and that much lower than that will tend to be overkill (fattening file sizes for no apparent (playback) visual gain). ![]() The only physical PC release to not have an ESRB rating is Angry Birds Rio.The games can be downloaded here.ģ Exciting Games In One!

![]() Fortunately, this looks better with this lighter color tone. The original model was heavily criticized for its color choices (it should have been black) and its non folding wings. The build is very sturdy so that it won't fall apart while swooshing. I got some ideas from 75055-1 - Imperial Star Destroyer. He needed a place where he could face with his anger issues.

As of right now they're showing Despicable Me 3, Cars 3, Wonder Woman, and the new Spiderman movie. My daughter loved it, I loved it, and we're going back when they show other movies. It was awesome seeing families sitting outside spending quality time. The best part about this "new" experience is that, contrary to years gone by where you watched the movie from within the confines of your car, now you can pull out your chairs and watch the movie under the stars. Fortunately, there were many movie goers who had set up big speakers and we were able to hear perfectly without having to use our car radio. GET to the drive-in around an hour early (although this somewhat depends on the movie/time). I was greatly concern that my car battery was going to die if I did that. Paramount plays their movies' audio through FM radio stations, and if you want to avoid keeping your car on and letting the battery run low, a portable radio is a fantastic option. Now, you tune in from your car radio, but I'm still not sure how that works. Like another poster wrote, long gone are the days where you had a post and speakers. Tickets are $10 per person, which I found to be extremely reasonable. There are two screens in the lot, and depending what movies you want to watch you to one or the other. On weekends they show three movies, and on weekdays two. I took my youngest daughter, who is 21 and had never been to a drive-in, and she was just as excited as I was. As a teen I lived fairly close to this drive-in and I remember trips with a car load of teens hiding in the back, going in for free. I was blown away when I learned that this drive-in was still in existence as I was under the impression that there were no drive-ins operating. For us, and the rest of the people there, it didn't bother us! The attendants are very good/transparent about this and told us at the "gate" (where you buy tickets) you have the option to turn around if this bothers you. BE aware that if you see a "darkly-lit" film (these tend to be horror films), it can be a little difficult to see them on the screen just due to lighting. ![]() It was a perfect time to stake out a spot (we were still, by no means, the first ones there). You can't buy tickets in advance/online, and we were seeing a Friday 8:30pm showing of a new horror movie, so we arrived around 7:30pm. GET to the drive-in around an hour early (although this somewhat depends on the movie/time).Paramount plays their movies' audio through FM radio stations, and if you want to avoid keeping your car on and letting the battery run low, a portable radio is a fantastic option. BRING your own portable radio! I bought a cheap one off Amazon the day before and it was a life saver.The attendants don't check your car so as long as you don't have the food in plain sight, you will be fine! BRING your own food! There's an old-timey restaurant at the drive-in (it's cute and has '80s arcade games in it) but the food is very overpriced and the menu is limited (a most-likely microwaved cheese pizza and popcorn are the main staples).Here are some of my big tips/takeaways from my experience at the drive-in: We saw a wide variety of people - friends, families, couples - and it was very easy to both enter and leave. The drive-in has "ridges" on the parking spaces so that everyone gets an equally elevated view of the screen. The movie started on-time and it was great to see that the drive-in (which has a huge lot) was nearly completely full on a Friday night. In short, it was amazing! It was so fun and everything was ran very smoothly. I saw that the Paramount Drive-In wasn't terribly far away (and was playing a decent horror movie) so we decided to go on a Friday night. (It’s the thing on your dashboard you’ve never used before.) Read on for where you can watch a movie through your windshield, from Malibu to the IE.My friend from out-of-state came to visit me in LA for the weekend and one of the things on his "bucket list" was to see a drive-in movie. You can read up on the policies for each spot on their respective websites, but know that all are following government regulations on social distancing and enforce the use of masks when you’re outside of your vehicle, and most require an FM radio to get audio. Around LA, shuttered drive-ins have re-emerged, temporary venues have popped up, and an existing drive-in or two outside of city limits are suddenly on our radar thanks to the pandemic. Now, the drive-in is making a comeback as a socially-distanced way to catch a movie without catching Corona. By the time most of us got to our teenage years, drive-ins had gone the way of pay phones and cafeteria soda, and we were left crowding into multiplexes, fighting over the cup holder with a stranger under the breeze of recirculated A/C. Drive-in theaters used to be a fabled relic of the past we knew (ironically) only from movies, where poodle-skirt-and-varsity-jacket-wearing teens from the ‘50s (and also John Travolta) would make out in convertible Thunderbirds under starry skies.

IN THE TABLE, when no HP equivalent has been provided, we have used the continuous power and multiplied it by 1.3 to indicate HP equivalent.When manufacturers have provided an HP equivalent we have used that. As noted above, there is a lot of leeway in how this is interpreted. HP is ‘HorsePower equivalent’ so that you can get an idea of the power of the motor in comparison to a HP rating you might be more familiar with. We have indicated what the measurement is, although in the table we have used peak power as equal to input power and continuous as equal to output. Some quote only peak power or continuous power, some quote input power and output power. Power Ratings – measured in kiloWatts kW power rating quoted is taken from the manufacturer website. We have not given comparisons to Imperial/US measures except in ‘horsepower equivalent’, which is in itself not standardized due to how the power is measured by each manufacturer. The table can be searched with any keyword – manufacturer, for instance, or can be sorted by any of the columns: Peak kiloWatt power, Continuous kiloWatt power, estimated HP equvalent, Voltage, Dimensions (Length, Width, Height), Weight, RPMs, Type of motor and cooling system (air, liquid, water), and whether it is regenerative – capable of recharging when the boat is under sail propulsion.Īll measurements are in metric.

When this muscle contracts, it reduces the size of the pupil. When bright light is shone on the eye, light-sensitive cells in the retina, including rod and cone photoreceptors and melanopsin ganglion cells, will send signals to the oculomotor nerve, specifically the parasympathetic part coming from the Edinger-Westphal nucleus, which terminates on the circular iris sphincter muscle. In bright light, the pupils constrict to prevent aberrations of light rays and thus attain their expected acuity in the dark, this is not necessary, so it is chiefly concerned with admitting sufficient light into the eye. The constriction of the pupil and near vision are closely tied. At this stage the pupils do not remain completely still, therefore may lead to oscillation, which may intensify and become known as hippus. After 25 years of age, the average pupil size decreases, though not at a steady rate. For example, at the peak age of 15, the dark-adapted pupil can vary from 4 mm to 9 mm with different individuals. However, in any human age group there is considerable variation in maximal pupil size. In the dark it will be the same at first, but will approach the maximum distance for a wide pupil 3 to 8 mm. When narrow, the diameter is 2 to 4 millimeters. The pupil gets wider in the dark and narrower in light. This causes the effect in one eye to carry over to the other.Įffect of light The pupil diameter can vary greatly due to various factors (primarily the pupillary light reflex), from constriction to as small as 2 mm, to dilation larger than 8 mm in some individuals, though the maximal dilation also varies substantially by individual and decreases with age The sensory pathway (rod or cone, bipolar, ganglion) is linked with its counterpart in the other eye by a partial crossover of each eye's fibers. These muscles are sometimes referred to as intrinsic eye muscles. The dilator pupillae, innervated by sympathetic nerves from the superior cervical ganglion, cause the pupil to dilate when they contract. When the sphincter pupillae contract, the iris decreases or constricts the size of the pupil. The iris contains two groups of smooth muscles a circular group called the sphincter pupillae, and a radial group called the dilator pupillae. This is known as the pupillary light reflex. Light enters the eye through the pupil, and the iris regulates the amount of light by controlling the size of the pupil. ![]() The iris is a contractile structure, consisting mainly of smooth muscle, surrounding the pupil. On the inner edge lies a prominent structure, the collarette, marking the junction of the embryonic pupillary membrane covering the embryonic pupil. The image of the pupil as seen from outside the eye is the entrance pupil, which does not exactly correspond to the location and size of the physical pupil because it is magnified by the cornea. In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop. In humans, the pupil is circular, but its shape varies between species some cats, reptiles, and foxes have vertical slit pupils, goats have horizontally oriented pupils, and some catfish have annular types. ![]() The term "pupil" was coined by Gerard of Cremona. The size of the pupil is controlled by the iris, and varies depending on many factors, the most significant being the amount of light in the environment. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil. The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina.
