On a regular cotton jacket the snow builds up and then melts and you're quickly soaked through with the wax it just never melts into the fabric. Fans pointed out the figures skin tone was incorrect, after it was unveiled at the Grevin Museum last week. While this process won’t remove stains and isn’t really intended for work jeans (I think), it is touted to kill any living organisms and make your jeans FEEL crisp and clean again. The jacket is not 100% waterproof like a rubber or plastic jacket would be, but it keeps you dry in light rain and it's especially good in snow. Fold your jeans neatly and place inside bag. Founded in Gothenburg in 2001, the Swedish denim company has been recognized for their work with sustainability, both environmental and social. It occasionally picks up light patches where the wax is still a bit thick and creased (especially around seams and pocket edges) - I have a 1500 watt heat gun that I use on these areas once in awhile, which melts the wax and lets it flow back into the fabric. With a wear and tear-way of thinking, reuse and repair program Nudie Jeans Co provides and maintains a tradition true to the fabric’s tradition and characteristics. It looked a lot like yours and was stiff as a board initially, but after a few wears it's loosened up and flexes like a normal jacket again. The Otter Bar is solid so for each patch on the jacket I had to 1) heat the patch of fabric up with an iron 2) rub the otter bar on the jacket to build up a layer of wax then 3) iron the area again so the wax melted and flowed into the jacket.

Shim my trunk lock because it didn't align perfectly with the hole.Ħ screws with matching nuts for the tail lights.Musical horns have been around for centuries and have served various purposes, from signaling danger to announcing a celebration. In order to install this kit I had to drill out the following:Įnlarge the 2 existing mounting holes on the panel.Ĭhop off and attach a spade on each cable on one of the taillights because it wasn't wired correctly. Now down to the actual work I needed to go through to install this kit. I had no complaints on the actual build quality of the products, but what was a bit of a bummer was that Sickspeed forgot to include 1 of the red/amber lenses as well as the other little goodies mentioned in the item's description (license plate frame, badge, lanyard, etc.) After emailing them, they shipped them out same day.Īlso, this kit includes absolutely no hardware for the taillights, but for some reason does include 2 screws (but no nuts) for the reverse light. Opening the boxes will reveal the tail lights and reverse light, which I thought were extremely well built and solid. The panel comes primed white and you can definitely tell that someone has already been sanding down the edges to make it nice and smooth (something I appreciated). When opening up the packaging you will find the main panel completely wrapped in bubble wrap, 2 medium sized boxes containing the tail lights, and 1 smaller box containing the reverse light. Here are some features of the pawpaw tree:Īs the caterpillars munch on pawpaw leaves, they obtain essential proteins and nutrients needed for growth and development. You may find these trees in moist, wooded areas in your region. The pawpaw tree serves as the primary host plant for these caterpillars. Diet and Predation Caterpillar DietĬaterpillars of the Zebra Swallowtail Butterfly have a specific diet, mainly feeding on leaves of the pawpaw tree (Asimina triloba). Your appreciation for these beautiful creatures will undoubtedly increase as you learn more about their development from egg to adult butterfly. While the zebra swallowtail doesn’t typically overwinter as pupae like some other butterfly species, its life cycle remains fascinating. Adult zebra swallowtails are known for their elegant black and white-striped wings and distinctive swallowtail shape. It will then need to find a mate and lay eggs to complete the life cycle. Inside the chrysalis, the caterpillar undergoes a process called metamorphosis, transforming its body into an adult butterfly.Īdult Butterfly Stage: Finally, the adult zebra swallowtail emerges from the chrysalis. Pupa Stage: After the caterpillars have reached a certain size, they’ll enter the pupa stage, forming a chrysalis. Their primary goal at this stage is to eat, consuming leaves and growing quickly. The caterpillars are initially black and white, but as they grow, they develop the distinctive green and yellow stripes. These eggs are usually found on the underside of leaves, providing some protection from predators.Ĭaterpillar Stage: Once the eggs hatch, small larvae or caterpillars emerge. Let’s break it down into stages:Įgg Stage: The zebra swallowtail begins as a tiny, round egg laid by a female butterfly on the leaves of its host plant, typically a pawpaw tree. The life cycle of the zebra swallowtail butterfly is fascinating. Red spot and blue scaling near the long tail-like extension.Pale green-white wings with black stripes.In summary, when identifying a Zebra Swallowtail butterfly, look for these key features: Their unique wing structure allows them to hover and maneuver effortlessly over and around their preferred host plants. Zebra Swallowtails are known for their graceful flight. However, their bold pattern might be helpful in confusing predators due to the contrasting shades and strong visual impact. The Zebra Swallowtail’s distinct colors and markings might not appear to provide much camouflage. Additionally, the hindwing features a prominent red spot and blue scaling near the long, white-tipped tail-like extension. These beautiful butterflies have pale green-white wings adorned with bold black stripes. Their size may vary, but you’ll generally find them falling within this range. Zebra Swallowtails have a wingspan ranging from about two and a half to four inches. Here, we’ll briefly discuss its appearance, size, and behavior. The Zebra Swallowtail butterfly is quite distinctive, so you can easily identify it by its unique features. In these areas, they thrive in the presence of their host plants, the pawpaw trees. They primarily reside in the southern United States, especially in Florida and parts of Texas. Zebra Swallowtail butterflies, known for their greenish-white wings adorned with bold black stripes, are native to North America. Keep your eyes open for these black and white patterned gems, and cherish every encounter with these marvelous pollinators. With this knowledge, you can better appreciate the wonder and beauty of zebra swallowtail butterflies as you encounter them in the wild. Areas rich in their host plant, the pawpaw tree, are particularly attractive for these butterflies, as it provides an essential source of nutrition for their caterpillars. Primarily, zebra swallowtail butterflies can be found in the eastern United States, residing in deciduous woodlands, near streams and rivers. Known for their distinct black and white stripes and long hindwing tails, they play a vital role in pollination and serve as a captivating subject for butterfly enthusiasts.Īs you explore these magnificent creatures, understanding their habitat is essential.

There are a few considerations to think through before you use a VPN, though, and a few steps you need to take to perform this little maneuver successfully. Say you’re traveling internationally for work and don’t really want to watch Italian Netflix, a VPN can make the network think your device is located in the U.S. For one, changing your YouTube location with a VPN can help you access content that isn’t available in your geographic area. There are a lot of reasons you might want to do this. You can change your iPhone location with a VPN just as easily as you can using your home computer. And this goes for desktops, laptops and mobile devices too. VPNs, or virtual private networks, allow you to spoof your digital location and cut through the proverbial red tape that blocks you from certain websites. How are you supposed to see what your favorite content creator is having for dinner if you can’t get on Instagram?

Step 2: Next, we arrange the factors along the top and right side of the grid, as shown below. For example, if you are multiplying a 2-digit by 2-digit equation, your grid will have two rows and two columns. The number of rows and columns will depend on the number of digits in the factors. To solve this equation, we follow the steps below: Let’s begin with an equation that does not require regrouping: 18 x 31. I’m going to explain this strategy step-by-step, with lots of pictures, but if you’d rather watch my Lattice Multiplication video, simply press “play” below! Otherwise keep scrolling for the step-by-step instructions. This is especially helpful when it comes to regrouping, as the numbers that are carried are also written within the grid to make the adding easier. Lattice multiplication utilizes a grid to keep numbers organized. How do you perform lattice multiplication? Looking for support with teaching this strategy and many others for multi-digit multiplication? See The Multi-Digit Multiplication Station (a self-paced, student-centered approach) HERE. If your students have mastered those mental math based strategies, and are ready for more, this is a fun one to teach! I do believe that before you teach this method, you should focus on mental math strategies that DO encourage number sense understanding, such as the partial products strategy, or box/window method (area model). Once students have a solid understanding of the place value concepts behind multiplication, some can thrive with traditional methods such as long multiplication, or this alternative – lattice multiplication. So why would you want to teach this strategy? Now let me begin this post on lattice multiplication by saying that this is not necessarily one of those strategies that enhances number sense understanding. We teach math in a way that enhances number sense understanding, so that students really understand what they are doing, rather than just memorizing a series of steps. We know that number sense is an essential component of today’s classrooms. Before I begin explaining this strategy, I do want to take a second to talk about multi-digit multiplication strategies in general. Lattice multiplication is an alternative to traditional long multiplication. The additional length of the SDS Plus bit also allows it to reach deeper into the material, which makes it more effective for drilling deeper holes and breaking through larger chunks of material. The SDS Plus bit, however, is designed with higher torque and lower speed, so it is better suited for working with heavier materials. Because the SDS shank is shorter, it won’t be able to reach as deep into the material as an SDS Plus bit. The SDS bits are designed with a lower torque and higher speed, so they are ideal for use with lighter materials and in lighter-duty applications. The differences between SDS and SDS Plus drill bits are mainly found in the strength and torque of the bit. The SDS shank is a short, round shank compared to the SDS Plus which is longer and slightly curved. Both designations refer to the types of shanks that the bits have. SDS and SDS Plus drill bits are both popular types of drill bits used for masonry and concrete drilling. What is the difference between SDS and SDS Plus drill bits? It is also advisable to use an SDS Plus extension with your SDS Plus bit if you are drilling into materials that need longer reach. Additionally, when using an SDS Plus bit in an SDS drill, it is best to take the SDS setting off your depth stop, if available, to avoid any potential damage to the SDS Plus bit. It is important to check the compatibility of the SDS Plus bit and make sure it is rated for the SDS drill that you intend to use. SDS Plus and SDS Max both have a standard shank size, but they are not interchangeable. Yes, you can use an SDS Plus bit in an SDS drill, but you must ensure the SDS Plus bit is compatible with your SDS drill. They wanted to understand who would survive and who would not if or when an American city was hit with an atomic bomb. It was American lives - not Japanese - they were hoping to save. This program would also prove to be highly controversial, because the researchers who arrived in Japan weren’t there to treat the survivors, but only to study them. That program would eventually be named the Atomic Bomb Casualty Commission (ABCC). In September 1945, just one month after the bombings of Japan, the US military sent a team of American doctors and geneticists to Japan to interview people who’d survived the attacks, looking to understand both the short and long term effects of radiation. But, in fact, the films and posters about ducking and covering were based on actual research of survivors at Hiroshima and Nagasaki. It’s considered the number one example of the kind of Cold War-era propaganda that seems totally ridiculous now - kitschy and absurd and unimaginably naive. The idea of “duck and cover” gets made fun of these days. The idea that with enough canned food, shelters, fearlessness (and maybe tattoos) the American people would be able to survive an atomic attack. It was just another manifestation of the concept of survivability. It sounds morbid in hindsight, but many kids at the time took it in stride. They called it a “walking blood bank” - no need for cold storage. In this case, the thinking was that if Russia attacked, the tattoos would make for quicker transfusions. In 1952, the Cold War was in full swing and the government was busy developing civil defense strategies - things ordinary citizens could to do to help protect the homefront. At the age of 16, producer Liza Yeager’s grandmother, who went to school in Lake County, was permanently marked in anticipation of a nuclear catastrophe. It was administered by the county and the idea was simple: to make it easier to transfuse blood after an atomic bomb. This experimental program was called Operation Tat-Type. Each one was in the same place on the torso, just under the left arm, and spelled out the blood type of the student. There, fingers were pricked, blood was tested and the teenagers were sent on to the library, where they waited to get a special tattoo. Ready to start therapy?

Most people develop schizophrenia in their late teens or early 30s. Its exact causes are unknown, but several things may play a role, including: Schizophrenia is a complex mental health condition. Learn more about the treatment options and approaches to schizophrenia. You can find a group in your area on the NAMI homepage. For example, the National Alliance on Mental Illness (NAMI) has a weekly support group for people with mental health conditions. Support groups can be another great way to get started and learn about additional resources. Most insurance companies, if you have insurance, will cover some of these services. You may want to reach out to your doctor about programs in your area, and assistance in getting enrolled. This includes talk therapy and social skills training. Psychosocial treatment is also often recommended. Since there are many types of these drugs, you should reach out to your doctor about your options, their pros and cons, and how to manage any side effects that may occur. Symptoms of schizophrenia are often effectively treated with antipsychotic medications. Schizophrenia is often managed with a combination of treatments, including medications and psychotherapy. difficulties planning or sticking with an activity like grocery shoppingĬheck out more about the symptoms of schizophrenia.Negative symptoms can be seen as behaviors that are missing or underdeveloped. Hallucinations and delusions are called positive symptoms because they represent additional behaviors not generally seen in people without the condition. Examples include hearing voices that aren’t your own, or seeing people that aren’t actually in the room. Hallucinations involve seeing, hearing, or feeling things that aren’t there.

There are transformerless models as well. Note that many systems provide isolation between DC input and AC output in high-frequency boost converter stage, and do not use a bulky low-frequency output transformer. In this case, their inputs are paralleled, and outputs are connected in series. However, many of them can be synchronized and stacked in a so-called master-slave mode for 120/240 VAC output. In practice, inverter models usually provide only single 120VAC. The solar wiring diagram above shows a configuration with an inverter that provides 3-wire split phase 120/240 VAC which is typical for US household systems. That is why a special peak power tracker that charges the batteries while forcing the PV array to operate at an MPP is an important part of any solar system design.Ī DC voltage from the battery bank is then converted to AC by a DC-AC inverter. This requires different loading depending on the illumination and ambient temperature. To extract the maximum power out of the array, the PV panels should operate near maximum power point (MPP) of their I-V curve. To protect them from overcharging or from discharging by reverse currents, normally they are connected to the PV array via a battery charger. The current from the PV array is charging the batteries. It is a device that is designed to open the circuit when a certain leakage current to ground from an ungrounded bus is detected. The main DC disconnect switch is followed by a DC ground fault interrupter. A metal oxide varistor (MOV) is commonly used in such applications. To reduce the possibility of a fire and to protect the system from a damage caused by lightings, it is recommended to have a voltage-clamping device across the DC buss. Since PV arrays are mounted outside, they can act like lightning rods. A DC disconnect switch should be installed near the place where the cables from the combiner enter the house. The combiner's frame or the PV arrays grounding conductor should be wired to a ground rod located as close as possible to the arrays. However, most battery chargers and inverters come factory configured for negative ground systems. In theory, you can ground either plus or minus. In all solar wiring configurations, if the DC voltage is over 50 volts, one of two DC busses should be grounded, unless the system has additional protections per NEC® 690.35. However, I understand, with a proper conductor size, up to three strings are allowed to go to the same fuse. If you parallel several strings of solar panels, it is desirable to use a combiner with a fuse or a circuit breaker for each string to prevent the panels' damage from possible reverse currents. PV panels can be connected in series and parallel- see various solar panel wiring methods. In a single-phase 3-wire setup it has to be the neutral bus. Particularly, one AC output conductor is supposed to be grounded. However, it still may be a good idea to do the installations and grounding in accordance with the National Electrical Code (NEC®) NFPA 70 and UL 1741 as well as local electrical codes. Of course, you should check if your local authorities have any permit and safety requirements. As far as I know, there are no regulations that specifically pertain to the off-grid PV systems because they may be outside the jurisdiction of electric utilities. PRINCIPLES OF THE DESIGN AND PV ELECTRICAL WIRINGīelow is a simplified solar panel system wiring diagram for an off-grid home. By the way, another reason batteries should be used off-grid is to operate the PV cells near their maximum power point. Fuel-powered electric gensets are also often used as an another auxiliary energy source that simplifies the isolated system's sizing. To reduce the size of the panels and the battery bank, solar systems for off-grid homes are often supplemented with wind turbines that can produce electricity at night and during cloudy periods. If the off grid home has no other power source, both the PV array and the battery bank have to be significantly oversized by design to account for possibly several days of inclement weather. |
