Red zone: less than 50% of your normal rate.Talk to your doctor about how to handle yellow zone results. Yellow zone: 50% to 80% of your usual flow rate.It means your condition is under control. This is the ideal zone and considered to be a normal peak flow reading. Green zone: 80% to 100% of your usual flow rate.Test results are classified as green, yellow and red zones. So, what are the 4 stages of COPD and what are their symptoms? Find out here. Albuterol (Proventil and Ventolin) is a beta 2-agonist.ĬOPD can be a progressive disease that is measured in stages. 15 to 20 minutes after using an inhaled, quick-acting beta 2-agonist.Ī beta 2-agonist medication is a medication that relaxes the muscles surrounding the airways helping them to expand.When you wake up in the morning and the late afternoon or early evening.If you cough or sneeze while breathing out, you will need to start again. Do not put your tongue in front of the mouthpiece.Blow into the mouthpiece as quickly and as hard as you can.You will blow air into the mouthpiece, which causes a small plastic arrow to move. This handheld instrument has a mouthpiece on one end and a scale on the other end. You’ll use a peak expiratory flow monitor to perform the test. The PEFR test is used to check for lung problems: When Does a Doctor Recommend a Peak Expiratory Flow Rate Test? You can adjust your medication or change environmental factors that affect your breathing. This is the only way to ensure you notice patterns when your flow rate is low or decreasing.įor example, when you notice these patterns you can take steps to prevent your symptoms from worsening into a full-blown asthma attack. Keeping ongoing records of your flow rate is important. It is commonly performed at home with a peak flow monitor. The peak expiratory flow rate (PEFR) test measures how fast you can exhale and is also referred to as a peak flow test. What is a Peak Expiratory Flow Rate Test? Rescue inhalers provide quick relief when your lungs get tight to avoid emergencies. Some are taken as pills or capsules, while others are inhaled.Ĭontroller medications are meant to work in the long-term, keeping your lungs open to improve your breathing while you are active. Several medications can help in the treatment of COPD. Your doctor will talk to you about changes you will need to make in your everyday life, including small changes that can significantly impact your breathing and prevent symptoms. Genetics can also play a role in an individual’s development of COPD, even if the person has never smoked or has never been exposed to strong lung irritants in the workplace. Most cases of COPD occur because of inhaled pollutants, such as smoking, second-hand smoke, fumes, chemicals and dust. With each one of these conditions, the primary symptom is increasing breathlessness (difficulty breathing). What is COPD?ĬOPD is a general term that describes a group of lung diseases including asthma, chronic bronchitis, emphysema and bronchiectasis. Using a peak flow meter for COPD is a critical part of your treatment, and you are the one responsible for using it correctly so that you get the correct treatment. If you have been diagnosed with chronic obstructive pulmonary disease (COPD), it is important to know what COPD is and how you can control your condition. With the Bitspower Digital Flow Meter Display, you can rest assured that you’ll stop leaks dead in their tracks!

Let us know how you felt also by "reacting" and commenting below. I hope this was a worthwhile blog post to read. How do you think tessellations can become an important part of life? One of the most common places to find tessellations is in nature. Here are three different examples of tessellations with pentagons. In this course you will learn about angels, polygons, tessellations, polyhedra and nets. Tessellations can be found in many different places, such as in nature, art, and architecture. Geometric shapes are everywhere around us. This can be done by using different shapes, colors, or sizes. Find out about regular and semi-regular tessellations. Tessellation is the process of creating a repeating pattern of shapes within a flat surface. I hope you learned some information today, but I wanna ask you this. Discover tessellation shapes and their demonstration of geometry. Image caption, Examples of tessellations. Get children involved in their Art with this KS2 lesson on M.C Escher. Children have the opportunity to create their own tessellation using a shapes Create a tessellation by drawing a template. Since these are regular hexagons, each interior angle of each hexagon are 120 degrees, and all the angles in one of the hexagons equal 720 degrees. A tessellation is a pattern created with identical shapes which fit together with no gaps or overlaps. Children are given examples of everyday tessellations which can be found in nature. It uses regular hexagons to form this natural mosaic around the surface area of the hive. Brick wall - Bricks may seem boring, but they create the most basic and recognizable example of tessellation in buildings. Pentagons have a total angle measure of 540 degrees, hexagons have a total measure of 720 degrees, and quadrilaterals have a total angle measure of 360.įinally, A honeycomb is a perfect example of a natural tessellation. In this shell, we see 3 irregular hexagons surrounded by pentagons, also surrounded by many quadrilaterals. A periodic tiling has a repeating pattern. You can also create great curved or organic looking patterns. A tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called tiles, with no overlaps and no gaps.In mathematics, tessellation can be generalized to higher dimensions and a variety of geometries. You can also create great curved or organic looking patterns. To get the most out of tessellations, it’s best to move away from texture and into the world of colour think intarsia and stranded. If the leaf motifs are the trees, planted at half-drop intervals, then tessellation is the wood, showing us the overall shape and character. A turtle shell shows a special tessellation (at least for Kristian) since they use multiple, different shapes, instead of seeing the same shape over and over again. This tessellation is an excellent example of how tessellations don’t have to be based simple geometric shapes. Tessellations refer to the geometric plan of the pattern as a whole. These worksheets are perfect for teaching letter recognition, beginning sounds, and proper letter formation. It’s about providing them with an opportunity to grow and learn. Using these Thanksgiving printables with preschoolers is not just about keeping them engaged or giving them a fun activity to do.
And remember, just because something is out of your control, this doesn’t mean your feelings are not legitimate. Surround yourself with loved ones, talk it out with a friend, take time out to spend with the people that matter the most. Stay healthy to increase your resilience. This is why it is really important to look after yourself. When we are tired, worn out or busy these triggers will often take an even firmer grip on us, making it hard to step back and manage them. Focus on what’s important, and don’t attempt to do everything You may need to accept that sometimes ‘good enough’ really is good enough. Try and focus on learning – what can you do differently next time? What are the positives you can take from this situation? Also, perhaps you need to review your standards – being practically perfect at all times just isn’t reasonable. Wallowing in self-pity, or beating yourself up is not productive. Making mistakes, getting things wrong or not delivering the winning pitch –can all cause bitter disappointment and unnecessary levels of self loathing. Sometimes the cause of worry or frustration is ourselves. Try reframing the issue – are you going to be worried, angry or upset about it tomorrow, next week, next month? What about next year? Looking at the bigger picture can help keep things in context. This means you need to find a way to accept what’s happening and move on. You can only ask other people to change their behaviour – you can’t make them do it. There are of course going to be times when having a talk doesn’t work. If it’s someone you manage, maybe you can suggest setting up a regular meeting instead. If someone constantly interrupts you with ‘urgent’ things (that aren’t), explain that this knocks you off track. If someone talks loudly, explain that it makes it harder for you to concentrate and ask him or her to speak a bit more quietly. Focus on facts, and how what they are doing impacts on you – try not to make things personal. In that case, you need to deal with it by taking them to one side and asking them to change their behaviour. Ok, so sometimes avoiding a co-worker just isn’t possible, and you are expected to work well with all of your colleagues. Or if a person you’re not too keen on keeps trying to distract you with idle chit chat, try moving seats and putting some distance between you. If you’ve identified a trigger, try to avoid it.Īt its most basic, if you’re irritated by having to queue for the lift – and you’re physically able – take the stairs. In our Emotional Intelligence training we ask people what coping techniques they have developed. So, in order to get calm, keep calm, and move forward in a productive and healthy way, we need to find a way to handle these triggers. At an adult, professional level we know that reacting and allowing these emotions to take over doesn’t look good – and is unlikely to further any career prospects. And they are unhelpful, unproductive and get in the way. These sometimes overwhelming feelings are the result of people or events triggering an emotional response, and we all have different triggers. You know the ones – where you feel the prickle of anger or upset, surges of frustration or even crushing levels of disappointment. We’ve all had bad days – and bad interactions with other people. Bad day? How to control your responses, and not let your emotions control you. "The reason probably has more to do with the fact that it was not a lot of extra effort to include XP as one of the supported platforms, because there is probably a shared code base that existed across multiple platforms," Hesse told CRN. The update was somewhat unexpected, said Peter Hesse, president and founder of Chantilly, Va.-based solution provider Gemini Security Solutions. The attack doesn't work if Flash is removed from the browser, but the company also recommended implementing other restrictions, including the use of its Enhanced Mitigation Experience Toolkit. Solution providers told CRN that the serious attack needed to be addressed quickly by Microsoft because workarounds designed to reduce the risk of an attack could be tedious for some firms. "We detected the attacker fast enough and implemented blocks prior to the attacker being able to move laterally." "To date, we have contained the breaches to the initial infection vector," Glyer told CRN, indicating that the attacks have not resulted in any data leakage. The zero-day exploit is being used by a cybercriminal organization that is known for carrying out targeted attacks to gain access to intellectual property, Glyer said. The attacks lure users into clicking a malicious link, which forwards victims to an attack website with the aim of gaining complete control of the victim's PC, FireEye said.įireEye Technical Director Christopher Glyer told CRN on Wednesday that the attacks also were detected at organizations based in multiple regions of the world, including companies with headquarters in Europe and the U.S. They also appear to be coming from multiple criminal groups. A spokesperson told CRN that the attacks expanded to government and energy-sector firms. organizations associated with defense and financial-sector firms. A spokesperson at FireEye, the firm that detected the attacks, told CRN that it saw them initially being waged against U.S. Microsoft issued an Internet Explorer security advisory on Sunday, warning users that zero-day vulnerabilities in its browser were being used in targeted attacks. "Unfortunately, this is a sign of the times and this is not to say we don’t take these reports seriously. "The reality is there have been a very small number of attacks based on this particular vulnerability and concerns were, frankly, overblown," Hall said. However, Hall called the threat "overblown." Users of Windows XP are strongly encouraged to a more modern operating system, said Adrienne Hall, general manager of Trustworthy Computing at Microsoft, in a blog post explaining the decision. Microsoft officially ended support April 8. The decision to issue a patch to Windows XP users is based on the proximity to the end of support for the operating system. Build out After the instance of SQLiteOpenHelper, call its getReadableDatabase() or getWritableDatabase() method Then the database can be created, and the database files will be stored in the /data/data//databases/ directory. The fourth parameter represents the version number of the current database, which can be used to upgrade the database. The third parameter allows us to return a custom Cursor when querying data, usually null is passed in. The second parameter is the database name, the name specified here is used when creating the database Weighed. This construction method receives four parameters, the first parameter is Context, there is nothing to say about this, it must have It can operate on the database. There are two construction methods in SQLiteOpenHelper that can be rewritten, generally the construction method with fewer parameters is used can. Do not The same is that when the database is not writable (such as the disk space is full) the pair returned by the getReadableDatabase() method The image will open the database in read-only mode, and the getWritableDatabase() method will be abnormal. Both methods can create or open an existing database (if the database already exists Open directly, otherwise create a new database), and return an object that can read and write to the database. There are two very important instance methods in SQLiteOpenHelper, getReadableDatabase() and getWritableDatabase(). There are two abstract methods in SQLiteOpenHelper, namely onCreate() and onUpgrade(), we must rewrite these two methods in our own helper class, and then in these two In this method, the logic of creating and upgrading the database is realized. First of all, you need to know that SQLiteOpenHelper is an abstract class, which means that if we want to use it, You need to create your own helper class to inherit it. Since there are good things that can be used directly, Then we naturally have to try it, and I will introduce the basic usage of SQLiteOpenHelper below. The helper class, with the help of this class, the database can be created and upgraded very simply. In order for us to manage the database more conveniently, Android provides an SQLiteOpenHelper helper. So let’s quickly take a look at how to use SQLite database in Android Studio.Ĭreate SQLite database in Android Studio: It’s hard to imagine how to use files or SharedPreferences to store these large amounts of data and complex structure data? But you can do it with a database To. Content and most conversations may also correspond to a contact in the phone book. When you need to store a large amount of complex relational data, For example, there may be many conversations in the SMS program of our mobile phone, and each conversation contains many pieces of information. Android embeds this extremely powerful database into In the system, the local persistence function has made a qualitative leap. And SQLite is much simpler than ordinary databases, it is very It can be used without setting a user name and password. SQLite database Not only supports standard SQL syntax but also follows the ACID transaction of the database, so as long as you have used other With relational databases, you can quickly get started with SQLite database. SQLite database is a lightweight relational database, its computing speed is very fast, It occupies very little resources, usually, only a few hundred K of memory is enough, so it is especially suitable for use on mobile devices. Sqlite Database in Android Studio Creating CRUD System: in this article, I am going to show how to create and connect SQLite database in android. deleting data from the SQLite database in Android Studio:.updating data using SQLite database in Android Studio:.adding data using SQLite database in Android Studio:.CRUD system using SQLite database in Android studio:.Upgrade SQLite Database in Android Studio:.Create SQLite database in Android Studio:. You have to do everything yourself.” I was telling him, “Father, let’s do something. It’s very hard, and I don’t want to help you. He was always telling me, “Lena, I don’t want you to be a musician. My dad is a musician, but he wasn’t involved when I was trying to do something. You have shows and interviews and you get tired, and it’s, “Why did you put your bag there? I want to put mine here.” Have you always wanted a career in music? It’s just about simple things when you get tired of each other, when you’re together for a very long time. She kills this boy and calls me, and I’m driving to her and taking her from there. She gets in trouble with a boy because this boy wants to hit her. She goes away and I’m driving a car, thinking about what’s going on, and I’m really sad. Lena: Julia and I have a problem between us and we quarrel. “All About Us” is really different than all the other videos. Lena: It was really funny to work with him. We were always smiling because he had so much energy, and he’s, “Girls! Girls! Wake up!” What was it like to work with Wonderland director James Cox? All of the know us really well, so they can understand what we feel, so it’s about us. Do you want to write songs in the future? We just want to be able to do more things ourselves. Lena: We don’t have a producer because we wanted to do it ourselves and be more involved in the process. This album feels more hands-on than your debut. Every song on our album is about some kind of danger. The American name is about dangerous people, dangerous feelings,dangerous characters. The Russian name of the album is People Invalids, but if you said that in America, they wouldn’t understand because it’s not about physical things. Lena: When you say something in Russian, in English it wouldn’t mean the same. Why is the Russian name of the record different from the American version? Our hearts and our bodies were like girls. Julia: When we came for the first time to the U.S.A., we were 16. When you released your first record, you said you didn’t want to grow up yet. We like how this word sounds, and the song is really pretty and calm. It’s for everybody because lots of people sometimes have trouble.“Obeyzanka Nol” means “I’m sorry.” Lena: It’s not really an apology for Japan. Didn’t you have to put an apology song on your new record for them? Lena: Actually, the most crazy fans are in Japan. Really? You don’t have a place you visit that has the craziest fans? Lena: I can’t say that in Europe people are more crazy, or in America people are more crazy. He’s Russian, but he’s lived in America maybe 11 or 12 years. Julia, we’ve got to know - are you single? I like restaurants, maybe going around Moscow. My friends go to clubs and bars every day. Lena: Yes, but mostly we wanted toget some rest. Was it neat to see so many countries on your first tour? Julia: I like London, I like Spain.… I like so many cities, but my favorite is Moscow. It’s terrible when you’re very far away from everybody, but it’s our work and we love that, so it’s life. It was really great to see my mom and my friends. Lena: I was flying home everymonth or month and a half formaybe one week when we had freetime. Did you get homesick when you were in California? They had thisnew room for recording, just for us. What was it like recording at the Village in L.A.? The Doors, the Rolling Stones, and Madonna have all recorded there. We just hope they don’t get between Lena and her childhood friend Julia Volkova. With Richard Carpenter (yes, of the Carpenters) and Sting both guesting on their new record, Dangerous and Moving, we’re not sure who these “boys” are. Still, when redheaded Lena Katina told us, “I’m kissing with my friends, always - not only with girls, but with boys also,” we began to consider: Are pseudo-lesbians hotter than the real thing? Perhaps. Sadly, the love between the girls of Russia’s t.A.T.u. They’re hot, and they’ve made out with each other in music videos like “All the Things She Said” - but they’re not hot for each other. Every song is about some kind of danger.” “Dangerous and Moving is about dangerous people, dangerous feelings, dangerous characters.

Thus, Na3PO4 - correct form, na3po4 - incorrect form. Compare: Co – cobalt and CO – carbon monoxide. Note: Always use the upper case for the first character in the element name and the lower case for the second character, as in the periodic table. The returned solution is then used to display the balanced equation. Therefore, the calculator below simply parses the chemical reaction, creates a system of linear equations and feeds it to the above-mentioned Gaussian elimination calculator. In short, it just keeps all fractions, and gets to a whole integers solution at the end. I have created a special calculator that implements the Gaussian elimination method – The General Solution of a System of Linear Equations using Gaussian elimination – in the form suitable for chemical reactions. However, the Gaussian elimination method actually could find a solution for any number of equations and unknowns. Of course, you could not expect that the number of unknowns will always be equal to the number of equations. This system could be solved by using the Gaussian elimination method. Now we can rewrite this system in matrix form: Here we have five equations for four unknowns, however, the last one is dependent on the fourth, so it can be omitted. They will form a system of linear equations: Then we write the balance equations for each element in terms of the unknowns: We start by introducing unknown coefficients: Let me illustrate this method by example. Therefore this method could be used for any type of chemical reaction (including redox reactions). So, you just need to create a set of algebraic equations expressing the number of atoms of each element involved in the reaction and solve it. Balancing chemical equations is the process of ensuring the conservation of matter. Therefore, the number of each type of atom on each side of a chemical equation must be the same. The algebraic method is based on the Law of Conservation of Mass – that matter can neither be created nor destroyed. This chemical equation balancer uses the algebraic method – which is usually quite complex for manual calculations, however, it fits the computer program perfectly. The last two are used for redox reactions. ✓ Multi-use virtual cards are ideal for managing all your different subscriptions so you’re always in control. ✓ Single-use virtual cards are perfect for adding security on unfamiliar merchant websites or when you make a big purchase.
