Stacks of books with school supplies10/4/2023 ![]() ![]() These holidays generally run in July or August. “I’m planning on getting the kids a couple of new items they want and school supplies that week,” Lakata said, adding that she’ll save 6% without sales tax. If so, in-person and online shopping for items like clothing, books, school supplies and electronics during the designated time frame could provide a 4%-7% pad to your budget. Search your state tax administrator’s website to see whether your state is one of several with a tax-free holiday. Here’s how to keep more money in your pocket this season. Those figures make the back-to-school season the second-largest spending period of the year, after holiday shopping. An additional $94 billion will be spent on back-to-college shopping. ![]() According to the National Retail Federation, families with children in kindergarten through 12th grade will spend a record $41.5 billion on back-to-school shopping this year. If back-to-school spending forecasts for 2023 are correct, every little bit of savings might help. “So if I can get like a big 48-count of pencils, I’m going to do that.” “I have the two kids and there’s a lot of overlap in what they need,” Lakata says. Lakata, a pre-K teacher in Maryland, uses tools like state sales tax holidays, cash-back apps and buy-nothing groups to keep back-to-school costs down. But thanks to some creative shopping habits, the mother of two isn’t stressed over back-to-school spending. When Meghan Lakata’s kids return to school from summer break, they’ll have new (to them) clothes and supplies. Institutions must have an NCES (National Center for Education Statistics) number or 501c3 tax status.Tired of ads?

Here’s how: As we shared earlier this month, schools are eligible to create a nonprofit account and benefit from tax-deductible donations through Walmart’s Spark Good Registry and Round Up programs, starting today. This year, Walmart saw an opportunity to help – building on the millions of dollars of support local stores and clubs provide schools each year through our local giving programs. What if schools had a way to list much-needed supplies that people could purchase, or to raise funds to help cover classroom expenses, year-round? Teachers often spend their own money to buy supplies for their classrooms, and according to the National Center for Education Statistics (NCES), supplies cost public schools nearly $1,000 per student. Back-to-school season always sparks conversation about how much schools and teachers must spend to support their students throughout the school year. ![]()

Even on the most loose setting, it still feels like it wants to slow you down faster than necessary.Īll those things are relatively minor compared to all the good! It's been quite awhile since I've been this happy with a car! I've found the adaptive cruise control isn't quite as smooth as some other vehicles I've driven. But, it doesn't matter much since my next complaint is lack of wireless Apple Car Play! You'd think for the 2022 model year this would become virtually standard, but it's not an option unfortunately! The wireless charging pad is a bit temperamental, You have to place your phone on it just right or else it'll quit charging after a few seconds. The push button gear selector is taking some getting used to, however it's not quite as bad as I was anticipating. The only negatives I have found so far include: If you want to knock down 30 mpg in an SUV, you'll need to sacrifice the space and powerful V6 and look for a small 4 banger. ![]() Again, coming from a V8 F150, so I welcome the extra 5-6 MPG. However, we did get a little snow last weekend and I decided to take it down (and back up) a snowy, muddy, rather steep hill on the back of my property and didn't get stuck!!įor what it is, fuel economy isn't bad! It easily gets the EPA rating and probably a little better if you're careful. Living in Georgia, I've had limited opportunity to test the AWD. It drives silky smooth, plenty of power, handles nice. I'm pleased … with the improvement in ride and handling. I'm coming from an F150 crew cab and don't feel like I'm giving up all that much passenger space, at least in the front. We are a family of 3 and not too far from being empty nesters, so have no need for a 3rd row. I've only had my Passport Trailsport for a couple weeks and 800 miles, but so far it has been the perfect vehicle! Tons of room passenger room and cargo space.

These groups have since been treated at the ranks of division, class and order. In 1975, Banks expanded on his earlier 1968 proposal that split it into three groups at the rank of subdivision. Īs additional fossils were discovered and described, it became apparent that the Psilophyta were not a homogeneous group of plants. The living Psilotaceae, the whisk-ferns, were sometimes added to the class, which was then usually called Psilopsida. Prior to that, most of the early polysporangiophytes had been placed in a single order, Psilophytales, in the class Psilophyta, established in 1917 by Kidston and Lang. Polysporangiophytes may or may not have vascular tissue – those that do are vascular plants or tracheophytes. This distinguishes polysporangiophytes from liverworts, mosses and hornworts, which have unbranched sporophytes each with a single sporangium. (The taxobox at the right represents their view of the classification of the polysporangiophytes.) The defining feature of the clade is that the sporophyte branches and bears multiple sporangia. The concept of the polysporangiophytes, more formally called Polysporangiophyta, was first published in 1997 by Kenrick and Crane. Fossils assigned to the genus Cooksonia, which is more certainly a polysporangiophyte, have been dated to the succeeding Wenlock epoch ( 433 to 427 million years ago). Īs of 2019, Eohostimella, dated to the Llandovery epoch ( 444 to 433 million years ago), is one of the earliest fossils that has been identified as a polysporangiophyte. Since these discoveries, similar megafossils have been discovered in rocks of Silurian to mid-Devonian age throughout the world, including Arctic Canada, the eastern USA, Wales, the Rhineland of Germany, Kazakhstan, Xinjiang and Yunnan in China, and Australia. The vertical stems were dichotomously branched with some branches ending in sporangia. The fossils were better-preserved than Dawson's, and showed clearly that these early land plants did indeed consist of generally naked vertical stems arising from similar horizontal structures. Lang published a series of papers describing fossil plants from the Rhynie chert – a fine-grained sedimentary rock found near the village of Rhynie, Aberdeenshire, now dated to the Pragian of the Lower Devonian (around 411 to 408 million years ago). įrom 1917 onwards, Robert Kidston and William H. speculate that this was because his reconstruction looked very unusual and the fossil was older than was expected. Dawson's discoveries initially had little scientific impact Taylor et al. Cross-sections of the upright axes showed that vascular tissue was present. The upright stems or axes branch dichotomously and have pairs of spore-forming organs ( sporangia) attached to them. The reconstruction shows horizontal and upright stem-like structures no leaves or roots are present. In 1859 he published a reconstruction of a Devonian plant, collected as a fossil from the Gaspé region of Canada, which he named Psilophyton princeps. ![]() ĭawson, a Canadian geologist and paleobotanist, was the first to discover and describe a megafossil of a polysporangiophyte. Megafossils are preserved parts of plants large enough to show structure, such as stem cross-sections or branching patterns. Microfossils are primarily spores, either single or in groups. ![]() Paleobotanists distinguish between micro- and megafossils. Extinct polysporangiophytes are known that have no vascular tissue and so are not tracheophytes.Įarly polysporangiophytes History of discovery While the definition is independent of the presence of vascular tissue, all living polysporangiophytes also have vascular tissue, i.e., are vascular plants or tracheophytes. The clade includes all land plants ( embryophytes) except for the bryophytes (liverworts, mosses and hornworts) whose sporophytes are normally unbranched, even if a few exceptional cases occur. The name literally means 'many sporangia plant'. Polysporangiophytes, also called polysporangiates or formally Polysporangiophyta, are plants in which the spore-bearing generation ( sporophyte) has branching stems (axes) that bear sporangia. unclassified fossil Polysporangiophytes.non-vascular fossil Polysporangiophytes.Modern polysporangiophyte, monarch fern is a vascular plant.

The Pro Keys is a folio-style keyboard compatible with 10.2-inch iPads, but there are versions suitable for 11-inch and 12.9-inch iPad Pro and iPad Air models. While folio-style options are available between these two, spending a bit more or a bit less will get you a better product. There's a fairly wide price difference between this pick and our best mid-range pick above. Overall, this folio keyboard has many additional features, and thanks to all its size variants, it's the best mid-range option for iPad Pro that we've tested.įor the best option at a budget price point, we recommend the ZAGG Pro Keys. There's also a trackpad for on-screen navigation, so you don't have to get fingerprints on your screen, and there's even a slot to hold an Apple Magic Pencil. The keycaps have a nice soft-touch coating to add some grip, which is helpful as the tile-like keycaps can be slippery. On the back of the case, there's a sturdy kickstand to prop your iPad up at a comfortable viewing angle. It also uses Apple's Smart Connector for power, so you won't have to charge the keyboard as it'll draw power straight from the iPad. It has size variants to fit 11-inch and 12.9-inch iPad Pro models and 4th and 5th-generation iPad Air models. It's got similar features and is sometimes closer in price to our first pick, the Apple Magic Keyboard for iPad 2021, but lately, it's gone up and down in price and may be considerably cheaper when you're reading this. If you're looking for a mid-range folio keyboard that offers good protection for your iPad, we recommend the Logitech Combo Touch. If you're planning on traveling a lot with your iPad, you might want the side protection offered by our next pick, the Logitech Combo Touch. ![]() However, this keyboard has a downside: the case doesn't wrap around the sides of the iPad and instead leaves them exposed. Plus, if you sit with your iPad on your lap, like a laptop, the keyboard is very stable and doesn't flex or flop over easily. The keyboard part has a rubber exterior, so the whole unit stays firmly in place on desks or other hard surfaces. The folio case attaches with a strong magnet on the back that holds your iPad in place. While this means the keyboard isn't compatible with any other mobile device, you just have to worry about charging your iPad and not the keyboard separately. It uses Apple's Smart Connector feature to connect to the iPad and draw power directly from it. As its name suggests, it's Apple's flagship model and is available in different sizes for the 11-inch and 12.9-inch iPad Pro and 4th and 5th-generation iPad Air models.

Many of the best keyboards for iPad Pro or iPad tablets come in folio cases, so you'll have to make sure it fits your specific device, while others are stand-alone keyboards, so you can use them as long as they have Bluetooth support. However, typing on a touchscreen can be frustrating, so there are keyboards specifically designed for iPads that you can use to enhance your typing experience.

In high-turbidity (low-visibility) areas of the coast, a surface expression is a must if the mooring is required in order to be located and recovered by a diver. Bottom mounted recorders with or without surface mooring currently have to be in depth that can be reached by divers to ensure successful recovery or be attached to an acoustic release. This can be mitigated using stretch hoses but come at high cost as well. The use of a surface expression, especially in high-current coastal areas bears the problem that wave induced motion and pull on the surface mooring causes significant noise, making it unsuitable for PAM noise studies. This is usually mitigated by the used of faired cable, which comes at high cost. The noise introduced by strumming negatively impacts the acoustic data quality. Mooring with line always bear the risk of strumming, , vibration of the mooring cable caused by currents. as on-line sensors on a traditional surface mooring connected to the mooring line and placed at a pre-determined depth in the water column. as bottom mounted recorders tethered to an anchor without release, deployed and recovered by diver as bottom mounted recorders tethered to a surface buoy for recovery as bottom mounted recorders without surface expression, which require a fixed weighted frame on the bottom of the ocean with an acoustic release and back-up floatation This limits the use of such devices to diving depth or, if simple mooring lines with surface expression are used, reduces data quality due to mooring induced noise, while low self-noise installments are key for successful PAM data collection.įixed PAM recorders can be deployed in four fashions : Hence, installations often are conducted from small vessels and deployed by divers or on mooring lines with surface expressions, and not within highly elaborate mooring deployments. These low-cost recorders are usually limited to water depths less than 500 m and have an endurance of a few days to a few months. Of particular interest here is that a plethora of different low-cost (<$5000USD) PAM recorders have been developed (Ocean Instruments SoundTrap, DesertStar microMARS, Develogic SVmini, RTsys Porpoise, Open Acoustic Devices Hydromoth) and made PAM available across a much larger scientific community, including smaller organizations and NGO’s. During recent years, the marine research community has started to follow this trend for various applications, e.g. ![]() Ī current trend in engineering is to (try to) replace large, expensive and highly sophisticated systems by swarms of smaller, cheaper, but more basic systems. On top of historical military applications, PAM is now widely used for biological, geological and meteorological questions such marine mammal occurrence and population density estimation, ocean ambient noise characterization, , soundscape measurements on coral reef to assess biological activities, marine biodiversity assessment, seismic monitoring, acoustical meteorology, estimation of water column or seafloor geoacoustic properties. ![]() Passive Acoustic Monitoring (PAM) in the ocean has become a standard technique across the oceanographic community. The TOSSIT’s design is rope-less, which removes any risk of entanglement and keeps the self-noise very low. The TOSSIT modular mooring system consists of a light and strong non-metallic frame that can fit a variety of sensors including PAM instruments, acoustic releases, additional power packages, environmental parameter sensors. It can be used in water as deep as 500 m, and can be deployed and recovered by hand by a single operator (more comfortably with two) in a small boat. Here, we present a low-cost, low self-noise and hand-deployable PAM mooring design, called TOSSIT. Such low-cost devices are often deployed by divers or on mooring lines with a surface buoy, which limit their use to diving depth and coastal regions. While in previous decades the high cost of acoustic instruments limited its use, miniaturization and microprocessor advances dramatically reduced the cost for passive acoustic monitoring instruments making PAM available for a broad scientific community. Passive Acoustic Monitoring (PAM) has been used to study the ocean for decades across several fields to answer biological, geological and meteorological questions such as marine mammal presence, measures of anthropogenic noise in the ocean, and monitoring and prediction of underwater earthquakes and tsunamis. ![]() AuthorWrite something about yourself.
