In England, they became instant classics. ![]() With his anchor deep in history, Mahan splices his sea battles with political and economic contexts, always inferring from the facts and never sailing to the fog of abstract theory.īut Mahan is an important read as well, for he helped drive - and still does - national policy.Īt the turn of the century, his books lent the firepower of history to the capital-ship race of Britain, Germany and Japan. ![]() "Those far-distant storm-beaten ships on which Grand Army never looked, stood between it and the dominion of the world." Cognitive distortions make already difficult realities even more challenging. These are examples of cognitive distortions, and just like everyone faces challenges, everyone will experience cognitive distortions-untrue and negative thought patterns. I am out of options.” Most likely, you have thought this or something similar because most people have. After one mistake, have you ever told yourself, “I can’t do anything right.” How about when you were in a tight spot, have you ever thought, “I feel overwhelmed.

"Telemedicine versus face-to-face delivery of cognitive behavioral therapy for insomnia: a randomized controlled noninferiority trial." Sleep 44.1 (2021): zsaa136. In 2020, one has received FDA-approval 3. There are several digital (computer-delivered) CBTI interventions that are now available. According to studies, telemedicine delivery of CBTI remains as effective as in-person CBTI 1, 2. Variations of CBTI, such as its online delivery, have increased its accessibility. Telemedicine and Digital Treatment Programs These shorter programs also focus on changing behaviors and opinions of sleep to improve sleep. These are condensed versions of CBTI that includes fewer sessions over a shorter treatment time course. ![]() ![]() Moreover, there are now abbreviated behavioral treatments for insomnia. While participating in a complete CBTI program may be most beneficial, shortened programs are now available to patients who can only attend a few sessions. This helps you feel sleepy during your bedtime and make it easier to wake during rise time. Stimulants keep you alert and make it harder for you to fall asleep.Ī sleep specialist may help align your circadian clock to your bedtime and wake time with the use of bright light exposure. Alcohol increases wakefulness in the second half of the night, while undigested food can disrupt sleep. Limit alcohol, stimulants like caffeine or nicotine, and food close to bedtime. Keep the bedroom quiet and safe, avoid watching the clock, and limit exercise within four hours before bedtime. Sleep specialists encourage that the last hour before bedtime to be reserved for unwinding. In addition, negative thoughts about the consequences of sleep loss are challenged and reduced. The transition from “trying to sleep” to “allowing sleep to happen” is a desired outcome. Increase relaxation and stress management activities to better cope with sleep-related worries. This increases sleep time while maintaining decreased time awake in bed. After marked improvements in quality of sleep, time in bed is gradually increased by 15-30 minutes increments.

Also, look for the green seal on the right side and the serial number which is located on the top right and bottom left corners. On the front side of the bill, you will notice a portrait of 7th American President Andrew Jackson. Pay attention to how both sides of the bill look like. Also, pay attention to the color of the seals and signatures on these notes. Things to remember are standardized texture, printing, and paper quality. These bills feature a stylish and distinctive design. Logically to be able to recognize a real 1934 $20 you’ll need to know the design of the bill in detail. This is accompanied by THE UNITED STATES OF AMERICA on the top edge and the denomination TWENTY DOLLARS below. The great thing is that both regular and Hawaii 1934 $20 bills have the number 20 in all four corners on both sides of the bill. The good news is that after reading this article you will be able to determine different series of 1934 $20 bills, as well as to determine if they are real or fake, rare or common. The reason was that Japanese planes attacked Pearl Harbor so the government wanted to be sure these bills would be worthless in case the Japanese get them. Now, you should know that there are regular 1934 $20 bills and 1934 Hawaii Pearl Harbor $20 bills.Īll denominations in that period were printed with a brown seal for exclusive use in Hawaii and the Pacific. The $20 bill from the 1928 series was a gold certificate, unfortunately, all series after that one lost the possibility of getting gold instead of paper money.ġ934 came and this is when our bill was printed for the first time. But since the demand for these bills was low they were rarely printed. This is when the Federa00l Reserve printing period began. Since most $20 bills were destroyed, Congress authorized the new $20 bill design in 1861. ![]() Fun fact, almost all 1775 $20 bills were destroyed after Civil War so they are extremely rare nowadays. It was produced during the Colonial Period, and the first confederate $20 bill appeared in Richmond, Virginia. However, sometime in 1775, the first $20 bill was printed in the Philadelphia mint. These bills were rarely used and printed, not to mention $10 or $20 bills. As you all know we mentioned a lot of times that back in the day people considered $2 and $5 bills as large denominations. Best equalizer settings for bass car7/23/2023 ![]() As mentioned before, all of the frequencies between these limits have different energy and feeling for humans. So this band is the basis of the equalizers. Human ears can detect frequencies between 20 Hz and 20 000 Hz. For example, to get more bass in a song, you can increase the low-end frequencies on your equalizer. These frequencies can be examined in three different categories: The low-frequency range, which is the bass the mid-range, which is the range of human voices and finally, the high-frequency range, which is the treble. Frequency RangesĮvery audio file consists of different frequency ranges. It is one of the crucial elements for audio engineers as it is a fundamental process when recording. You can find equalizers in many sound systems, from your home theater setup to your amp or car radio. ![]() It boosts or reduces specific frequency ranges to balance and clear the sound. An equalizer is a processor which adjusts different audio frequencies, emphasizing some over others. In order to find the perfect equalizer settings, you need to understand what an equalizer is and how it works in the first place. However, there can be minor adjustments depending on the room, the sound system, and the genre. In this sense, the perfect equalizer setting is ideally the flat one. But, you may play with the frequency bands just a little bit to emphasize the ranges that the genre you are listening to requires. High-quality speakers and headphones generally sound great even without an equalizer. For example, you can reduce the bass in a boomy car radio or reduce the high-end frequencies on damaged earphones to avoid hiss sounds. If your speakers or headphones sound poor with a flat equalizer, you may play with the dials a little to achieve a non-disturbing sound. However, the adjustments should always be small. An equalizer can help you avoid these issues. Some sound systems and rooms have peaks and dips, coloring and changing the sound. This issue becomes more apparent with low-quality headphones and speakers as they can not handle all the frequency ranges successfully, leading to muffled, cracked, or distorted sound.īut that does not mean an equalizer is unnecessary. Altering the EQ for tracks will likely make them sound worse unless you have very good reason to do so (for example, altering the sound to compensate for a very bad speaker system). Music releases are generally put through a comprehensive mastering process where a mastering engineer tweaks and gets the sound right before releasing the track. This is because playing with the equalizer distorts the sound and what you listen to becomes something different than the music was originally intended to sound like. So, a flat equalizer, meaning that all dials are set to zero, or a turned-off equalizer provides the highest quality sound. Well, the best equalizer setting is the one that does not change anything. Read on to learn how to make the best with your equalizer. If you really want to tweak the EQ when listening to music, it may be better to play just slightly with the equalizer settings without distorting the sound too much. As every listener has different tastes, you may find some songs to be relatively weak on some frequencies or too bright on others. When audio engineers mix a song, they produce them to sound good on any kind of device to any kind of listener in any kind of setting. Taking control of your audio by cutting the frequency ranges you do not want to hear and boosting the ranges you want to hear more sounds quite perfect for music lovers. If you are a music enthusiast who is looking for the best sound when listening to music, you may have found yourself playing with the equalizer settings at some point. Conversely, Equalizers are an essential tool when it comes to producing, mixing, and mastering music. Please note, we’re referring to the use of equalizers in the context of listening to music. However, they can be useful as a last-resort when compensating for poor speakers or headphones. Equalizers distort the sound of the original master recording. The best equalizer setting is one that is turned off or one that is set to “flat”, meaning that all dials are set to zero. Arch support slippers for ladies7/23/2023 ![]() ![]() My relationship with Vivaia shoes began in early 2021 when their affiliate marketing team offered to send me a pair of their “sustainable” Aria 2.0 flats to try. This post is my brutally honest review of Vivaia shoes, and why I don’t love this company. You’ll find stylish options from brands such as Teva, Hoka One One, Clarks, Oofos, New Balance, and Superfeet from retailers like Amazon, Nordstrom, REI, and more.I have A LOT to say on the subject of Vivaia shoes. The best shoes for plantar fasciitisīelow, we asked physical therapists and podiatrists what they consider the best shoes for plantar fasciitis (including sneakers and workout shoes, dress shoes, sandals, and slippers), along with their recommendations for removable insoles to make any shoe more plantar fasciitis friendly. If you need flats for dress shoes or work, however, look for those with a slight heel (around a half inch) to minimize stretching on the plantar fascia, as well as a shoe that stays on your foot without toe gripping (i.e., one that has elastic or other straps to secure the shoe to your foot). The same generally goes for sneakers without arch support, like Converse or Vans (unless you add orthotics, heel cups, or insoles), and flats. Those cute flip-flops that sell for $1? Probably not the best plantar fasciitis shoes. What to avoid when buying shoes for plantar fasciitisĪvoid flat, non-supportive shoes or sandals, Dr. They’ll also provide additional arch support, which can offer further relief from plantar fasciitis pain, Yolanda Ragland, DPM, a podiatrist and founder of Fix Your Feet in New York City, tells SELF. ![]() You can consider pairing your shoes with orthotics or insoles that have substantial heel cups to help with cushioning and shock absorption to avoid heel pain, Eby says. “You'll want a shoe with a deep heel counter and plenty of mid-foot arch support,” Carla Gamez, DPM, a podiatrist at Illinois Bone & Joint Institute (IBJI), tells SELF. In general, the best shoes for plantar fasciitis will fit correctly (i.e., not too small and wide enough to fit your foot comfortably) and have the right amount of support. How to choose the best shoes for plantar fasciitisīy choosing better (read: more supportive and well-cushioned) shoes, you can take a solid step (heh) toward reducing this annoying foot pain in the future. Your choice of footwear can also be an aggravating factor, whether you’re running, walking, or standing for long stretches of time. Some factors that can make plantar fasciitis worse include tight calf muscles, repetitive high-impact activities like running, a rapid increase in weight-bearing activity, prolonged standing or walking, and flat feet or very high arches. Plantar fasciitis often feels like a stabbing or aching pain in the sole of your foot, usually near your heel, which tends to be more intense in the mornings or after you’ve been off your feet for a while. Repeated stress on the plantar fascia can cause damage or small tears that can lead to inflammation. It helps support the long arch of the foot and provides shock absorption while you walk and run. The plantar fascia is a fascial band or ligament that runs from the bottom of the calcaneus, or heel bone, to the base of the toes, Susan Eby, PT, MS, owner of Eby Physical Therapy in New York City, tells SELF. ![]() What is plantar fasciitis?īefore we get into the causes of plantar fasciitis, it’s helpful to think about the anatomy of the foot region first. That’s why playing the preventive game is so important: The best shoes for plantar fasciitis can help relieve the tension in your feet (especially your heels) and hopefully help you avoid these most annoying of days. If you have plantar fasciitis, this can be even more of an issue, since that uncomfortable feeling can quickly escalate to aching, stinging, or even pain. Nothing can dampen a day of running errands, working on your feet, or strolling around town like realizing-only after heading out the door-that your shoes simply don’t feel great. Caffeine half life with vegetables7/23/2023 ![]() In June 2018, the California Office of Environmental Health Hazard Assessment (OEHHA) proposed a new regulation exempting coffee from displaying cancer warnings under Proposition 65. Evidence from the American Institute for Cancer Research concludes that drinking coffee may reduce risk for endometrial and liver cancer, and based on a systematic review of a large body of research, it is not a risk for the cancers that were studied. They cited the beneficial health effects of coffee, with improved antioxidant responses and reduced inflammation, both factors important in cancer prevention. However, many cancer experts disputed the ruling, stating that the metabolism of acrylamide differs considerably in animals and humans, and the high amount of acrylamide used in animal research is not comparable to the amount present in food. California’s law Proposition 65, or The Safe Drinking Water and Toxic Enforcement Act of 1986, fueled the ruling, which requires a warning label to be placed on any ingredient from a list of 900 confirmed or suspected carcinogens. Regardless, in March 2018 a California judge ruled that all California coffee sellers must warn consumers about the “potential cancer risk” from drinking coffee, because coffee-selling companies failed to show that acrylamide did not pose a significant health risk. However, there is not yet evidence of a health effect in humans from eating acrylamide in food. It was classified in the National Toxicology Program’s 2014 Report on Carcinogens, as “reasonably anticipated to be a human carcinogen” based on studies in lab animals. Acrylamide is also found in some starchy foods that are processed with high heat like French fries, cookies, crackers, and potato chips. The 2018 uproar in California due to warning labels placed on coffee products stemmed from a chemical in the beverage called acrylamide, which is formed when the beans are roasted. Coffee also appears to lower inflammation, a risk factor for many cancers. Caffeine itself may interfere with the growth and spread of cancer cells. Coffee has also been associated with decreased estrogen levels, a hormone linked to several types of cancer. Various polyphenols in coffee have been shown to prevent cancer cell growth in animal studies. For example, coffee may stimulate the production of bile acids and speed digestion through the colon, which can lower the amount of carcinogens to which colon tissue is exposed. Does the benefit stem from the caffeine or plant compounds in the coffee bean? Is there a certain amount of coffee needed a day to produce a health benefit?Ĭoffee may affect how cancer develops, ranging from the initiation of a cancer cell to its death. Still, the cumulative research on coffee points in the direction of a health benefit. Low to moderate doses of caffeine (50–300 mg) may cause increased alertness, energy, and ability to concentrate, while higher doses may have negative effects such as anxiety, restlessness, insomnia, and increased heart rate. Human response to coffee or caffeine can also vary substantially across individuals. What defines a cup is the type of coffee bean used, how it is roasted, the amount of grind, and how it is brewed. The cup of coffee you order from a coffee shop is likely different from the coffee you brew at home. Coffee and HealthĬoffee is an intricate mixture of more than a thousand chemicals. A moderate amount of coffee is generally defined as 3-5 cups a day, or on average 400 mg of caffeine, according to the Dietary Guidelines for Americans. One 8-ounce cup of brewed coffee contains about 95 mg of caffeine. Plant chemicals: polyphenols including chlorogenic acid and quinic acid, and diterpenes including cafestol and kahweol. ![]() state pass legislation that coffee must bear a cancer warning label? Read on to explore the complexities of coffee. Additional accumulating research suggests that when consumed in moderation, coffee can be considered a healthy beverage. By 2016 it was exonerated, as research found that the beverage was not associated with an increased risk of cancer on the contrary, there was a decreased risk of certain cancers among those who drink coffee regularly once smoking history was properly accounted for. In 1991 coffee was included in a list of possible carcinogens by the World Health Organization. And yet this beverage has been subject to a long history of debate. Coffee lovers around the world who reach for their favorite morning brew probably aren’t thinking about its health benefits or risks.

Topographic map contour interval7/23/2023 ![]() Pending cliffs can have one line crossing over the additional (this is the just time those lines can cross), with the one line appearing as dotted.īe familiar, however, that smaller cliffs can happen between the contour lines, even in areas with smooth slopes.Ī cliff 15 feet elevated, for instance, along a flow channel or due to slight faults, would not certainly indicate whether that cliff lies between two contour lines, particularly if they have a higher contour gap. If the relief is a vertical cliff, the contour lines nearly come together and can glance as if they are merging. Reading the contour lines Where the contour lines get extremely close, an almost precipice happens. The near the contour lines arrive, the additional inclined the terrain will be. The farther the contour lines arrive on the map, the smoother the slope of the earth is. The contour lines never cross, as a point on the map cannot possess two different heights at a similar time. A single contour line denotes an equal elevation line, which indicates that if the contour line computes an elevation of 1000 feet above average sea level, every point along that line is 1000 feet above average sea level. The Contour Lines indicate the shape of the earth. The horizontal distance between two points on two consecutive contour lines for a provided slope is known as the horizontal equivalent.As intervals are for the computation of the vertical elevation of an area, a similar way to compute the horizontal distance is termed Horizontal Equivalent.Earthquake estimation for the dam, bridge, or road can be found with the help of contour intervals within the map.To find the height of the intermediate point, the interval is utilized.In a larger map, index contour lines are much less to maintain the map and are simple to learn.A higher interval is utilized for a larger area and smaller intervals for a smaller area.Interval is utilized when a large space is to be mapped to a small piece of paper.The uses of contour interval in surveying are as follows, ![]() The number of lines acquired in the above step is 4 and added with 1.Now count the number of non-index lines contour lines between 70 as 4.The difference between the two selected index contour lines 71 is 7100 – 7000 = 100.Let’s assume two index contour lines, 70, and compute the interval between them.Considering the above map for the calculation of intervals, the steps involved in contour interval computation.Step 5:-The last step is the quotient of the difference between two index lines (step 2) and the number of lines between two index lines plus 1 (step 5). For Example: If the number of lines between two index lines is 5. Step 4:-The number of lines acquired in the above step is obtained and added with 1. Step 3:-Directly count the number of non-index line contour lines between the two index contour lines specified for the contour interval computing in the 1st step. To obtain the difference, subtract the higher elevated line from the lower elevated line reading. Step 2:-Now compute the difference between the two selected index contour lines established from a map. Step 1:-First of all, locate two index contour lines that are named with a particular elevation. The computation of the contour intervals is as below, In the above picture, the dark lines with reading are index contour lines. These marked or tagged lines are remembered or termed index contour Lines. To maintain the contour map easy and understandable to read, not every contour line is marked with its elevation reading. Locate the difference between the two elevations.Ī contour map contains contour lines of a given geographical region. The biggest number indicates the uphill rise. Discover the elevations of two adjacent index lines. These index lines will be noted with their elevation. On most of the maps, each fifth contour line, indicated as a heavier or darker line, is an index line or index contour. Understanding how to compute the interval becomes a valuable skill. It refers to the vertical distance or difference in elevation between two successive contour lines on a map or a topographic profile.Ī map legend usually specifies the contour interval on the map, but sometimes just a portion of a map is available.
