8/23/2023 0 Comments Springfield 9mm compact for saleAs I wrote at the time, “The end result should be no surprise - with that long frame, even the 3.8-inch barreled model isn’t small or easy to conceal. That provides you great ammo capacity, but at the cost of concealability. When the XD-M Elite line was introduced about a year ago the four models offered barrel lengths between 3.8 and 5.25 inches, with either iron sights or Springfield’s OSP (Optically Sighted Pistol) option, but every one of those guns had a full-length frame. There is some takeup, with a surprisingly crisp (at least for a striker-fired gun) trigger break. At the time of the XD’s introduction its crisper-than-the-competition trigger pull was another reason 1911 fans tended to gravitate toward it. Both the original XD and the newer XD-M pistols sport uniformly good trigger pulls from the factory. Which rear sight you see depends on the model. Every model but the OSP versions have front sights with red fiber optic inserts. You get full-length steel recoil spring guide rods with these guns, no matter the size. Both the barrel and slide have a corrosion-resistant Melonite finish. The slides have forward and rear cocking serrations. Interestingly, if the grip safety isn’t depressed, you can only pull the slide back about half an inch far enough to check the status of your chamber, but not enough to chamber or eject a round. Also, like the 1911, they are one of the few striker-fired pistols with a grip safety. For the people who hate Glocks because of their aggressive grip angle, the Springfield XD and XD-M pistols have always been popular because they have a grip angle similar to the 1911. Springfield’s 3.8" Compact is a concealable version of the new XD-M Elite line, and offers bilateral controls, a detachable magazine well, steel sights, and a number of other improvements. (Firearms News photo)Īs polymer-framed, striker-fired pistols go, the XD-M pistols are easy to spot in a crowded field. Let’s just say the XD-M Elite line is tweaked for performance, and with a 14+1 capacity in 9mm, short frame, and a 3.8-inch barrel the 3.8" Compact model is the one best suited for concealed carry, but before we dive into the specifics of this model, and the differences and/or improvements to the “Elite” line, let’s go over the basics of the XD-M. The newest XD line from Springfield is the XD-M Elite, and initially it was offererd in four models, but Springfield has just introduced a fifth - the 3.8" Compact. They are all available in different sizes, finishes, and calibers, and are made in Croatia to Springfield’s specs. These are polymer-framed pistols, and all but the XD-E are striker-fired guns (the XD-E has an external hammer). There is the original XD series, the enhanced XD-M models, the compact XD-S, and the newer XD-E. They offer more versions of the XD than some companies make guns, period. The universe of these pistols has of course expanded (just about every company which makes a pistol now makes one which meets that general description), but the number of models from the Big 3 has expanded as well. For a number of years, if you wanted a reliable, polymer-framed striker-fired 9mm pistol in the United States, your only real choice was one of the “Big 3”- a Glock, a Smith & Wesson M&P, or a Springfield Armory XD.

8/23/2023 0 Comments Halon fire extinguisherThis makes them unsuitable for use on or in the vicinity of complex and often sensitive aircraft electrical systems. However, although these types are the most effective fire extinguishing agents in general use, they both leave a very fine, powdery residue after discharge which includes particles of sub-micron diameter which is difficult if not impossible to clean up. Both types may be used safely on fires where electrical circuits are present. Extinguishing agents in common use generally are either formulations based on sodium bicarbonate - suitable only for fires involving flammable liquids and gases - or those known as ‘ABC’ which are usually based upon ammonium phosphate and are suitable for use on fires of all origins. The search for Halon alternatives for use on aircraft has been in progress for at least 20 years and has only recently led to potential success in the form of the product marketed as 'Halotron'. Where a portable Halon extinguisher is used by cabin crew, it is usually recommended to consider donning a smoke hood before discharging it so as to eliminate this risk, but for pilot use on the flight deck, this will not be an option and risk awareness is the only defence. The toxicity of the Halon gases, especially the combination which makes up Halon 1211, is such that use in confined spaces requires care to minimise any inhalation of the discharged gases. The magnitude of this effect, however, is relatively small compared to chemical inhibition and thermal effects, the former of these being the predominant one. Dilution is a simple matter of reducing the collision frequency of the oxygen and fuel source so that there is a reduction in chemical reaction rates. Halon gas mixtures are not only inert but of low temperature when released from their pressurised state. The rate of the combustive chemical reaction decreases rapidly with reductions in temperature and, if the concentration of added inert gas is high enough, the flame chemistry fails altogether. Temperature reduction occurs, whenever a non-reactive gas is added to a flammable gas, because the heat liberated by the reaction of oxygen molecules with a fuel source must be distributed into the overall environment. Fluorine atoms react with free radicals and form strong chemical bonds which neutralise combustion but can only do so once and are then “consumed.” The physical effects are both temperature reduction and dilution.Bromine, Iodine and Chlorine atoms act catalytically so that each atom participates repeatedly in the scavenging of important free radicals from the combustion gases. The chemical effects, which are dominant in their overall effect, are achieved by the atoms in the gas directly inhibiting combustion in two different ways: How Halon Extinguishers Workīoth Halon variants work by a combination of chemical and physical effects. However, the search for alternatives of comparable effectiveness has proved difficult and success limited, so they remain in wide use on board aircraft for most applications. As a result, their manufacture and use have been banned for many years in most countries and non-essential uses have been eliminated. The chemical constituents in Halon gases, and the products of the reactions they induce when discharged on fires, have been identified as causing damage to the Ozone layer. However, the fumes are toxic if inhaled and all practicable precautions should be taken when they are used. They do not produce residues and therefore do not cause secondary damage. They work mainly by chemically interrupting the reaction described as the ' Fire Triangle' (Fuel-Oxygen-Heat) which must be sustained for a fire to continue. Halons are electrically non-conducting and have been acknowledged as the most effective universal extinguishing agent for aircraft use. Halon 1301 is used only in fixed extinguisher installations typically cargo holds or engines and is a total flooding agent.Halon 1211 is used only in portable extinguishers and is a streaming agent.They exist in two forms - as Halon 1211, BromoChlorodiFluoromethane (CBrClF2) also known as 'BCF', and as Halon 1301, Bromotrifluoromethane (CBrF3). Halons have, until recently, been in almost universal use in aircraft fire extinguishers, both portable and fixed. Halons are fire extinguishing agents which are gaseous when discharged in the aircraft environment. 8/23/2023 0 Comments Sight words worksheets for kinderOne game that was surprisingly popular was call sight word pop, now while you can make this your self or even get your students to make it, there are options to buy it and we have a link to the product below.Need a fun, interactive activity to help practice sight words? We literally have thousands of Sight Word Worksheets to be able to practice learning, writing, and reading the sight words! Is there an order to teach sight words?.We have some tips and ideas in the resources section below, including a full guide on how to teach sight words and links to some of the best online sight word games as well. While there is no denying that kindergarten sight word worksheets are useful, and allow students and parents to have a record of progress there is more ways to teach sight words than jsut using pen, paper and worksheets. You can use a variety of strategies to make the process easier for your child on of which is of course kindergarten sight word worksheets, and others we have listed below. This way, they are less likely to become frustrated when they encounter new words. You can start teaching your child to recognize and learn sight words as early as preschool. Worksheets certainly help with this by providing a running reading record of students progress that can be referred to later as a refresher or as a recap. In fact, it can be a fun way to engage your children in the learning process. They are also used in early print material, making them a good way to build the foundation for reading. Sight words are high frequency words that are very common in everyday conversation. Whether you are a Kindergarten teacher or a parent, it is important to teach your child to recognize and learn sight words. Are Worksheets Useful To Teach Sight Words Sight words include colors, pronouns, and some verbs that all are usually taught early on in English lessons. However many sight words in english are also high frequency words and very commonly used in language, they also are some of the simplest and you may well have introduced them already to your children and students. You can do this by playing fun games that incorporate sight words which we also have here on the site as well. Third, you need to focus on fostering your child’s love of reading. For example, if you have a child with dyslexia, you may need to spend extra time to introduce sight words and we have further articles on this here on the site. Second, you need to make sure that you teach them in a manner that is beneficial for them. Some kids are ready for them at a young age, while others need to be more prepared. First, you need to determine your child’s readiness to learn them. Whether or not you should teach sight words in kindergarten depends on a number of factors. What is the Difference Between High Frequency and Dolch Words? Should you Teach Sight Words in Kindergarten? They help the child learn the differences between words that are pronounced the same and words that are spelled differently. Those words are the building blocks of learning how to read. Using the Dolch list, children are introduced to two hundred and twenty “service words” and 95 high-frequency nouns. One is the Dolch list, which includes preK-3rd grade nouns, and the other is the Fry list, which ranks words by their frequency of use in literature. There are two lists of sight words that are widely used. These words are also some of the most common words in English. Learning these will help students improve their writing skills and become better communicators and develop fluency skills. Hence the name sight words! Our kindergarten sight word worksheets here on this page ( linked above) and other sight word resources we have will help to achieve this. So exercises are required to help students recognise these words by sight. T hey are words that may, but many do not, follow phonics rules and phonics decoding will not help students to read and pronunce these words. Sight words are commonly used words, which make reading easier.

Learn more about Propagating Plants You wouldn’t want to plant it in a heavily used area. Creeping thyme would make an excellent groundcover for a formal herb garden.Ĭreeping thyme can take some light foot traffic which makes it a good ground cover for small pathways that are only used occasionally or stepping stone pathways. Creeping thyme has very shallow roots and doesn’t need much water so planting it with other plants that use more water is a great idea. Without some type of mulch the water will quickly evaporate. By placing it underneath and around shrubs it can help keep the moisture in the soil where it will work for the shrubs. Growing Conditions for Creeping ThymeĬreeping thyme can tolerate the hot summers here in Tennessee very easily. It also keeps the soil cooler in the hot summer. You’ve heard the saying “Nature abhors a vacuum”, by keeping the ground covered with a mulch of some kind will prevent weeds from getting what they need to sprout and eliminate any vacuums. In a garden anywhere light touches will help germinate a seed. You might be wondering why a groundcover like creeping thyme is useful? Groundcovers are a living mulch. Keep it moist and roots will develop in a week to two weeks. Just take a small 2 inch stem of the plant and stick it into your rooting medium. You also propagate creeping thyme through cuttings. |
