In Universe 25, a population of mice would grow within a 2.7-square-meter enclosure consisting of four pens, 256 living compartments, and 16 burrows that led to food and water supplies. Universe 25: Calhoun's Experiment with a Rodent UtopiaĮxpanding on his earlier studies, Calhoun devised his ultimate research experiment. Hitting the public just as vast urban expansion saw growing numbers of college grads flocking to big cities for work opportunities, many viewed the article as a warning of what could happen to the human race if populations continued to rise at their current rate. In 1962, Scientific American published Calhoun's observations from his research in the article "Population Density and Social Pathology," wherein he coined the phrase "behavior sink" to describe the results of overcrowding - namely the breakdown of social functions and the collapse of populations - in the enclosed rodent environment. The population would trail off to extinction.After that, the rodents would develop either hostile and cliquish or passive and anti-social behaviors.The mice would meet, mate and breed in large quantities.Over the course of these experiments, the same sequence of events would transpire each time: However, the population capped out at 200 after subdividing into smaller groups, each of which comprised merely a dozen individuals.Ĭontinuing with these studies during the 1950s, Calhoun set up a more complex enclosure to examine how further groups of rodents would behave in a sterilized, predator-free environment. Supplying the critters with unlimited food and water, he expected to see their population swell to 5,000 over the course of the 28-month experiment. Early Rodent StudiesĬalhoun began his experimental research on rodents in 1947 when he studied an enclosed group of Norway rats at a barn in Rockville, Maryland. Consequently, the “rodent utopia project” has been a subject of interest among architects, city planning councils, and government agencies around the world. Though wildly controversial when first made public, Calhoun's theory has raised concern over the years that the social breakdown of Universe 25 could ultimately serve as a metaphor for the trajectory of the human race. That, in turn, inevitably leads to extinction. In his theory, he suggested that overpopulation spawns a breakdown in social functions. The study confirmed his grim hypothesis, based on earlier studies of the Norway rat in small settings. Eventually, they established social orders that created inside and outside factions, and soon mating ceased altogether. Within the enclosure known as Universe 25, several pairs of mice bred a population, which ultimately swelled to 2,200. Calhoun (1917-1995) conducted a behavioral study of captive mice within a nine-square-foot enclosure at a rural facility in Poolesville, Maryland.

Next, dry each half well with a paper towel. Slice the chicken breasts in half to make them smaller (you can skip this if the breasts are already small). I like to triple the seasoning blend to have on hand for air fryer pork chops and chicken thighs.īutter – The chicken is finished with butter for moisture, flavor, and to enhance the color of the golden crust. Spices and seasonings – A mixture of garlic powder, smoked paprika, onion powder, oregano, salt, black pepper, and a pinch of cayenne gives the chicken a succulent, savory flavor with a kick. Olive oil – An oil with a high-smoke point, like olive oil or avocado oil, is ideal for pan-frying chicken over high heat. You can also use pre-pounded chicken breasts, if available.
You’ll then see the configuration screen, where you can load a project’s configuration from disc, or start with the defaults.Īs this is a simple walk-through, nothing needs to be changed. So just click Next in the bottom right-hand corner. If you had the professional version you’d have three options.Īs we’re using the community version, we only have one. You’ll see the first screen, which you can see below. Once downloaded, run it with java -jar ~/Downloads/burpsuite_community_v1.7.30.jar. I’ve had mixed success with the operating system-specific file. The download page normally gives two options, one specific to your operating system and a plain JAR file. The first thing to do is to download a copy of the community edition, which is version 1.7.30 as I write this post. It’s going to be based around a basic, one-page, application which returns the string hello world as the page’s body, along with a small collection of headers. Given that, the walk-through will be quite unsophisticated. That said, I’m intending this to only be a starting off point. While I’m not intending, at least at this stage, to write a longer series, if there’s enough interest, it just may end up that way. Given that, I decided to write this short introductory Burp Suite guide for other newcomers like me. Yes, there are loads of tutorials and blog posts about it.īut at least to this newbie, they seem to assume a lot of prior information and understanding. To be honest though, at first it wasn’t a tool which I found particularly (visually) appealing.Īdditionally, I didn’t find it that simple to get started with either - especially as a newcomer! I hope that you can see that just from this short list, it’s a pretty powerful tool. You can perform passive scans looking for information disclosure, and insecure use of SSL.Īnd this is just a fraction of what’s on offer. You can perform active scans, such as OS command injection and file path traversal. You can automatically modify responses by creating rules that operate on a range of criteria, including headers, and request parameters.Īdvanced scanning. You can intercept requests and responses, whether that’s just to view, modify, or drop them. Intercepts browser traffic using a man-in-the-middle proxy. You can scan for SQL injection and cross-site scripting (XSS) vulnerabilities, as well as for all vulnerabilities in the OWASP top 10. Here’s a quick overview of what’s on offer: While not the best looking tool (at least from my personal perspective), it has an absolute plethora of functionality for testing web application security. It is a proxy through which you can direct all requests, and receive all responses, so that you can inspect and interrogate them in a large variety of ways. The tool is written in Java and developed by PortSwigger Security. If you’re not familiar with Burp Suite, here’s a brief overview, from Wikipedia:īurp or Burp Suite is a graphical tool for testing Web application security. And one of the tools that I’ve started using is an open source tool called Burp Suite.īefore I took on the role, I’d only heard a little about the software, when Dale Meredith briefly mentioned it in the Ethical Hacking course, which I took recently. The display has a backlit for good visibility both day and night. In the center of the handlebar is the LCD display that shows the pedal assist level (there are 4 levels), speedometer, odometer, trip odometer, battery level, and estimated range! The estimated range is a cool feature because it will estimate your range remaining based on the current battery level and what pedal assist level you are in. The Kenda Kwick Bitumen 700x45c tires have an efficient road tread with channeling to dissipate water. You can also see the kickstand, rear rack, and fender attachments to the frame. Here is the rear Shimano M355 hydraulic disc brake with 160mm rotor. These hydraulic brakes have a very solid feel with progressive modulation. The front disc is a 180mm diameter rotor. Shimano M355 hydraulic discs brakes are used front and rear. A 142mm wide x 12mm diameter rear thru axle provides for solid side to side stiffness of the rear wheel. This pedal assist system uses a cadence sensor and wheel speed sensor.Īnd here is a look at the left side of the 350 watt mid-drive motor.Ī SRAM X7 rear derailleur shifts through the 10 speed Shimano 11-32T cogset. Wide alloy platform pedals provide a solid grip.Ī Currie Electro-Drive 350W mid-drive motor provides the pedal assist up to 28 mph and it has a peak torque of 73 Nm. The battery can be charged on or off the bike and the charging port is on right side of the battery pack. The charger is about the size of a laptop charger and it takes 4 to 6 hours to charge an empty battery. Note how the downtube has been formed to create a flat surface for the battery pack. Here’s a look at the frame after the battery pack has been removed. The 2 supplied keys can fit an ABUS lock so that you have the same key for the battery and bike lock. The battery is removed by unlocking it from the frame with the supplied key and sliding the pack to the side off of the frame mount shown here. Notice the frame tubing and how it blends with the battery pack form to create a cohesive look. On the left side is the on/off button and battery level indicator towards the bottom of the pack. The battery can be charged on or off the bike. The battery pack lock and charging port is located on the right side of the bike. The 48V 8.7ah (417 Wh) lithium battery is mounted on the downtube of the frame providing a low and centered weight distribution, which is good for overall bike handling. This prevents the fork from bobbing up and down when you stand out of the saddle and pedal hard. The RockShox Paragon fork also has a lockout dial for a more efficient ride on smoother roads. The IZIP E3 Dash is a Class 3 electric bike per California law which is a speed pedelec providing pedal assist up to 28 mph.Ī RockShox Paragon suspension fork with 65mm (2.5″) travel is spec’ed on the front to smooth out rough roads and SKS fenders with mudflaps are spec’ed front and rear. You can also see the internal cable routing exiting the triangular shaped top tube and the rear rack attachment at the seat stays. Here’s a look at the seat tube junction with solid aluminum welds. The frame also features a lot of internal cable routing to add to the clean look. The headtube junction features smoothed welds for a very clean look and the FSA zero stack integrated headset is also a nice touch for a minimalist appearance. To start thing off we will take a closer look at the 6061 aluminum frame that has some uniquely shaped hydroformed tubing. It can also be a versatile touring eBike with its component and accessory spec. The IZIP E3 Dash is ready for flying around town with it’s max assist speed of 28 mph. Part 2 of the IZIP E3 Dash reviewwill give you info on the ride characteristics, results from the range test, pros, cons, and overall thoughts on this eBike.Īlright, let’s take a closer look at the IZIP E3 Dash! In this first part of the review you will get a detailed look at this bike with a BUNCH of pictures and the specifications. This 350 watt mid-drive speed pedelec (up to 28 mph) commuter style eBike has a smooth ride with a healthy assortment of accessories for $2,599. The fast and versatile 2017 IZIP E3 Dash eBike has arrived for testing and review.
"I wore them after a tough yoga class and definitely felt a boost in my lymphatic drainage," she says. Women's Health assistant social media editor Isabel McMahon loved how comfortable they were, on top of being stylish. The socks are designed like tights, so you can pair them with your prettiest dresses and skirts. The feet are also boarded, which adds a slight massaging effect on the soles. To give you support where you need it the most, Threads' compression socks feature light graduated compression that provides support to tired and achy legs. Material: 64% cotton, 17% polyester, 13% nylon, 6% spandex For each pair of Bombas socks purchased, the company gives a pair to someone without the means to buy their own. Not only are Bomba's compression socks made of high-quality, soft materials, but they also help those in need. "They were so comfortable that I didn't take them off for the rest of the day when I got to my destination! When I finally took the socks off that evening, my feet and legs weren't swollen." Maridel also notes that she has short legs, so she loved that the Bombas felt like a perfect fit. I wore the Bombas compression socks for one long travel day (two and a half hours driving and over a two-hour train ride)," she says. "I've tried other compression socks before, but some were too long (I'm short), and others were TOO tight and would leave welts. They're even great during pregnancy, according to Women's Health senior deputy digital editor Maridel Reyes, who noted they helped with her swelling legs when she was around 25 weeks. "I realized how effective they were on the return trip when I forgot to put them on after boarding (big mistake) and arrived home with swollen ankles and achey feet," Jennifer adds.ĭesigned with a Y-stitched heel which creates a natural cap around the heel, the actual socks are super supportive and great at preventing swelling, too. These particular socks are a little wider at the calves, so you won’t get annoyed adjusting them in tight spaces or tucking them in pants. The light fabric didn't make me overheat in the tropical climate either," she says. "They came through and my feet and ankles stayed comfy through a full travel day of flying and car and boat transfers. WH Fitness editor Jennifer Nied notes that they were so easy to slip on and off, that she wasn't sure they'd work-but they exceeded her expectations. Gentry enjoys using Comrad socks because they’re not too tight, but great for when you’re still hot from a workout or in a tight space on a plane. Some colors are only available in select sizes.We’ve organized our picks by discussing the socks offering the firmest compression first and those with looser, more casual fits farther down. Segal’s that are notably easy to pull on and off and socks from Vim & Vigr, a brand that covers nearly every possible foot and calf size (in several fabric options, colors, and patterns). Our picks include a snug-yet-soft merino/bamboo blend from Sockwell a rugged budget option, Go2Socks a stretchy cotton-nylon blend from Comrad that boasts appealing modern styling ultra-comfy socks from Dr. To find the best compression socks, we consulted folks who wear them for all types of situations: during pregnancy, while working on their feet, for running, after working out, when traveling, and just because.Īfter considering dozens of socks, and testing 29 pairs since 2017, we’ve found five that are comfortably snug (yet still reasonably easy to put on), maintain their elasticity following multiple washes, and come in ample sizes and colors. Recognizing that sacrifice, Midway’s Devastator, a re-creation of the one flown by Torpedo Eight’s sole survivor, Ensign George Gay, will be displayed alongside a Dauntless dive bomber and Wildcat fighter, honoring the men and airplanes who fought the pivotal battle. The loss of Torpedo Eight wasn’t in vain their heroic charge kept the enemy off balance, disrupting Japanese plans to launch a quick counterstrike against the American carriers. Though the plane was relatively slow and lightly armed, SBD pilots and gunners also shot down 138 enemy aircraft. He adds, “The replica arrived in pieces and took over 2,000 hours to assemble, paint, and get the cosmetics right.” Asked about its relevance in a museum setting, Loftus points out: “There is nothing like it in the world unless you go underwater to get one.” While the Midway aircraft carrier museum doesn’t ordinarily display replicas, “we had no qualms about displaying this one,” says Walt Loftus, the museum’s airwing director. Indeed, it’s so well fabricated that a greasy oil pan placed on the floor beneath the engine could fool even the most discerning airplane buff. Underpowered, vulnerable, lacking in range, and exhausting to fly for any length of time, there was little to love. While the Zero-sen was credited with shooting down many SBDs, the rugged dive. Made of metal tubing, wood, and foam, the faux Devastator looks like the real deal, complete with corrugated skin. Navy Douglas SBD-5 Dauntless dive bombers of Bombing Squadron 16 (VB-16), Carrier Air Group 16, from the aircraft carrier USS Lexington (CV-16), fly over the invasion fleet off Saipan, on 'D-Day', 15 June 1944. The SBD Dauntless dive-bomber was a key cog in the US Navys aerial arsenal. Soon after the battle, the torpedo bombers were withdrawn from frontline service and, of the 129 Devastators built, none survive today except for a few wrecks at the bottom of the Pacific Ocean.īut, in 2019, San Diego’s USS Midway Museum acquired the next best thing: the Devastator replica used in filming last year’s Midway. All were shot down only one man survived. On the eve of the Battle of Midway, Torpedo Squadron Eight’s skipper, Lieutenant Commander John Waldron, steeled his men for battle with these prophetic words: “If there is only one plane left to make the final run-in, I want that man to go in and get a hit.” The next day, June 4, 1942, he led the squadron’s 15 Douglas TBD Devastators in a desperate attack against the Japanese fleet. During Doc's first visit to 2015, he has the machine refitted to fly in addition to standard road driving, and he replaces the nuclear reactor with a Mr. In the first film, following Marty's accidental trip from 1985 to 1955, Doc has no access to plutonium in 1955, so he outfits the car with a large pole and hook in order to channel the power of a lightning bolt into the flux capacitor and send Marty back to 1985. The time machine is electric and requires a power input of 1.21 gigawatts (1,620,000 hp) to operate, originally provided by a plutonium-fueled nuclear reactor. After Marty travels back to 1885, the fuel line and fuel injection manifold both suffer damage, leaving the car unable to move under its own power. In the third film, a note left by Doc's 1885 self reveals that the DeLorean's flying circuits (added by him in 2015) were destroyed by the strike. In the second film, the destination time display malfunctions and begins to show a series of random dates, causing Doc to be sent back to 1885 when the DeLorean is struck by lightning with him inside. In the first film, the car has starter problems and has a hard time restarting once stopped, much to Marty's repeated frustration. The DeLorean suffers assorted malfunctions and damage over the course of the trilogy. Vents on the back heat the vehicle after time travel. After the trip, the exterior of the DeLorean is extremely cold, and frost forms from atmospheric moisture all over the car's body. In the destination time, immediately before the car's arrival, three large and loud flashes occur at the point from which the car emerges from its time travel. Observers outside the vehicle see an implosion of plasma as the vehicle disappears, leaving behind a trail of fire aligned with the DeLorean's tires (which can also appear in midair), while occupants within the vehicle see a quick flash of light and instantaneously arrive at the target time in the same spatial location (relative to the Earth) as when it departed. The actual speedometer on the production DeLorean's dashboard only goes up to 85 mph, and the car itself was criticized for being underpowered. Various proposals have been brought forth in the past by fans of the movie franchise for why the car has to be moving at 88 mph to achieve temporal displacement, but actually the production crew chose the velocity simply because they liked how it looked on the speedometer, modified for the movie. A digital speedometer is attached to the dashboard so that the operator can accurately gauge the car's speed. Surrounded by an electric current similar to a Tesla coil, the whole car vanishes in a flash of white/blue light seconds later, leaving a pair of fiery tire tracks. As it accelerates, several coils around the body glow blue/white while a burst of light appears in front of it. After entering a target date with the keypad inside the DeLorean, the operator accelerates the car to 88 mph (142 km/h), which activates the flux capacitor. The operator is seated inside the DeLorean (except the first time, when the remote control is used), and turns on the time circuits by turning a handle near the gear lever, activating a unit containing multiple fourteen- and seven-segment displays that show the destination (red), present (green), and last departed (yellow) dates and times. The control of the time machine is the same in all three films. In 2021, the time machine was added to the Library of Congress's National Historic Vehicle Register. Its time travel ability is derived from the "flux capacitor", a component that can allow which allow the car to travel in the past or future (though not through space), when the car accelerates to 88 miles per hour, which requires 1.21 " jigowatts" of electricity. In the Back to the Future franchise, the DeLorean time machine is a time travel vehicle constructed from a retrofitted DMC DeLorean.
