What Are P, T and NP in Chemistry?

What Are P, T and NP in Chemistry?In this short article I am going to discuss what are P-T, PP and NP in Chemistry. I am hoping that after reading this, you can better understand how P, T and N make up our daily lives and how these basic elements get used.P stands for Propane, and P-T stands for Propane-to-Trans-Gas, which is what you use to separate the two mixtures. It is used to find all the gases in a mixture, this is why all the hoses are used to extract them. It also works to look for other elements that are in a mixture.T stands for Tetra-Phenyl-Acetate, and this is what we put in our gasoline. These are usually referred to as T-P-A because they are used as additives, or simple matter and which helps to improve our gas mileage.Next we have N stands for Nitrogen, and this is the element that makes up the nitrogen in our atmosphere's. Nitrogen is what we breathe, it is what we drink, and it is used in almost everything. N in Chem is usually abbreviated as N and is usually used w ith another element in order to tell the difference between the first and second type of element.Finally we have NP stands for Nitrogen-Nitrogen, and this is actually just a fancy way of saying NH 4 N. We actually know this by its abbreviation, NO. NO is the main form of Nitrogen, which are used in our vehicles, and which helps to get rid of our emissions.When learning how P, T and N in Chemistry are used, you are probably interested in what is NP. NP stands for Nitrogen-Platinum, and this is what we use in to treat the emissions of our vehicles.If you are a student that is looking to learn about these concepts, please take my advice and do not be afraid to ask for help. Your teacher may even be more than willing to explain the concept better.

What to Know About College-Level Math

What to Know About College-Level Math When you go to college, youll more than likely have to take at least one mathematics course as part of your general education requirements. Whether its algebra, geometry, calculus, or statistics, the first math classes that you take in college will present new challenges that you may not have faced in high school. Depending on your major and/or any AP credits you may have earned in high school, you might be exempt from certain levels of college math, or you might not have to take any at all! Whether youre looking for an interesting elective to switch things up, or youre facing several more years of math, here are some things to be aware of so you can succeed in college-level math 1. Take a math placement test Your college or university will likely have a placement test to help ensure you are situated in your optimal level of math in this new environment. For example, trigonometry at your new university may mean something different than trigonometry at your old high school. However, if you have earned a sufficient score on a qualifying exam like AP Calculus, AP Statistics, or an SAT Subject Test in Mathematics you may be able to move on to the next math class level immediately. Or, your exam may simply satisfy the mathematics requirement for your school/major. Talk with your advisor to check on what math credits you personally need to complete your college program. [RELATED: 5 Tips for Taking Better Math Notes] 2. Seek insights from upperclassmen about math classes and professors Juniors and seniors at your university will probably have recommendations on which math classes to take and which ones might be less helpful. Their experiences with the campus culture and with their professors can tell you a lot more than what youll get from simply looking at a course title and description. Some professors classes and teaching styles might be better fit for certain students, for instance perhaps certain professors cater best to mathematics majors, while others present material in a way that is more compelling to students studying another major. Furthermore, consider your goals for your field of study. Taking a class like Classroom Practices in Elementary School Mathematics might be great for an education major, whereas Mathematical Cryptology could potentially benefit a computer science major. Consult with upperclassmen in your department to get an idea of what math classes you should take and when. 3. Get subject-specific materials for the classes you take Not only should you bring your textbook, notebook, calculator, and pencils to the class, but think about any additional supplies that might benefit this specific course, like a protractor or a more advanced graphing calculator. Read the syllabus to see what materials the professor lists and recommends. There will probably be assignments every week, along with quizzes and tests every few weeks, so also make sure you have a planner where you can record these tasks and their deadlines. [RELATED: Study Strategies for Math] 4. Remember that professors have office hours For each course you take, there is a separate block of time that your professors schedule each week. During this time, students can come into the office and talk about classwork. Professors want to see you and help with areas of weakness, whether your weakness is differential equations, algorithms, problem solving, etc. Plus, the professors teaching assistants often have meeting times as well, so they can also be great resources for students who need more one-on-one attention outside class time. If you find yourself having scheduling conflicts with a lot of these office hours, you could also consider math tutoring. Your college-level math courses will likely be harder than the math you took in high school, but you have more freedom to choose what classes you take and from whom. Plus, your courses will probably relate more to what you want to focus on as a career. Even though the first math classes you take at your university may challenge you, they will also provide you with a deeper understanding of mathematics, as well as how to be a successful college student.

Learn English Grammar Your Daily Dose of Online English

Learn English Grammar Your Daily Dose of Online English Step by Step ESOL Grammar to Perfect your English ChaptersDay One: The Evolution of English GrammarDay Two: Parts of Speech and How to Use ThemDay Three: Double-Function WordsDay Four: Grammar ClausesDay Five: Marking Time with Verb TensesDay Six: Aspects of StyleDay Seven: The Best Grammar ExercisesEvery animal communicates, but only humans use more than individual sounds. We string them together in complex patterns that give meaning, both overt and implied - through context clues.Overt meaning is what a word or sentence represents; implied meaning is conveyed by word choice, tone, and body language.Human languages have a structure that is defined by rules for every aspect of communication. This collection of rules is identified by the blanket term: grammar.Sir William Jones first recognised patterns of speech and writing, sometime during the 1780s, while analysing Latin, Greek and Sanskrit. He found these grammars to be fully formed; complete in every aspect of their language.Grammar has developed in the last three thousand years, but it has not improved and it has not degenerated. It has merely changed.Slow and constant change, without improvement and without degeneration, is a characteristic of grammar in all languages. - Christopher MulveyBe that as it may, the English language is our focus. Let us explore it, from development, through evolution, to the impact of globalisation on our native tongue today.Along the way, we will study tricky aspects of English grammar and vocabulary.Grammar evolves but does not grow or stagnate. Source: Pixabay Credit: Geraltetymology?The West Germanic language already had a complete grammar system.  As the tribal languages melded into our beloved English, the grammar rules simply transferred from the old tongue to the new.Through other influences, mainly French and Latin, the English language in turn adopted, rejected and further cultivated aspects from other tongues to create the unique and distinctive speech that nearly two billion people worldwide can speak.And millions more, like you, strive to learn. Day Two: Parts of Speech and How to Use ThemYou, who are learning English as a second language, make a conscious effort to study each word's function and the meaning it gives to the idea you are trying to convey.If we think of vocabulary as the building blocks of language, it is critical to understand differences from one type of 'block' to another, and how they should be arranged for maximum effectiveness.Nouns are naming words.Anything you can see, touch or talk about is given a name.Nouns can be either common or proper.Your name is a proper noun. So are names of mountains, buildings, rivers, tunnels and monuments.Proper nouns and titles are capitalized. That is why our queen is called The Queen. Every doctor in every English-speaking country is addressed in English as Doctor, or Dr. and our teachers as Mr., Mrs., Miss,  Master  or Mistress.Important moments in time are capitalised, too. The Ice Age happened a long time ago, but World War II surviv ors are still alive today.For more rules on when to capitalize a noun, you can refer to this page.Be it Verb or a PredicateVerbs have several functions in the English language, the main one being to describe actions.Verbs can also tell us about mental activity like thinking, or represent a state of being. Verb conjugation and usage is one of the most difficult aspects of English grammar for Esl students, especially English learners whose native language verbs never change forms.Besides conjugation â€" changing verb endings to match pronouns or nouns, verb tenses are a particular challenge for non native students of English.The English language has twelve common tenses to indicate when action happens, if it has yet to occur, or if it is already complete. There are a further four special tenses, to be used only in certain grammar constructs.We will talk more in-depth about verbs later on.Adjectives and AdverbsThese words are describers. They add depth to our communications and help us visualize what is being talked about.Curious, he chewed his food thoughtfully as he pondered the question.This sentence contains a descriptive to a noun and to a verb.Can you find them? Imagine this sentence bare of any extra information:He chewed his food as he pondered.With this basic sentence, we have no idea what his state of mind is â€" indicated in the first sentence as curious.We have no clue what he is pondering. Maybe he is just wondering if he has enough milk for his morning tea.We have no indication of his mood.The use of descriptives is essential for good communication but, as the idiom goes: too much of a good thing can be bad.Many who learn English as a second language tend to saturate their speaking and writing with descriptives.Warning! Liberally sprinkling such words throughout your spoken or written English can reduce your fluency by making your sentences too cumbersome to speak clearly.Prepositions and ConjunctionsPrepositions are words that describe a relationsh ip between a noun/pronoun and some other word in the sentence.My English books are behind my computer.My books are on my desk.This page can tell you more about prepositions.A conjunction connects two related ideas.My reading comprehension is good but my listening skills are poor.Both ideas expressed in this sentence relate to English skills. They are joined by a conjunction. The DeterminerWords that give a measure of something, such as: a, an, the, some, and those all help you determine which specific items are being discussed.Hand me those  IELTS answer sheets, please.Those indicates a specific pile of exam answer forms the speaker would like to have given to him.Omitting determiners â€" or using the wrong one is common mistake made by English learners.These words are vital to English comprehension. Without determiners, we cannot know exactly what the speaker is talking about.Here is a great lesson on determiners and how to use them.These are the major parts of speech. Next, we wil l discuss double-function words.Double-function words expand English vocabulary Source: Pixabay Credit: Piro4DDay Three: Double-Function WordsWe all know how tricky English grammar can be. English vocabulary is at times even more treacherous!For example:The words before and after might have been among your earliest English language acquisitions.Did you know they can serve three separate functions, depending on where in the sentence they are positioned?When they precede or follow the clause they depend on, they are conjunctionsWhen they come before a noun or pronoun, they are prepositionsWhen used independent of any clause and away from pronouns and nouns, the two words are considered adverbs.Can you make up sentences in which before and after fill their various functions?Nouns as AdjectivesAre you an English teacher or an Esl student?In this sentence, English and Esl â€" although generally nouns, both function as  adjectives, describing the teacher and the learner, respectively.Have you encountered an instance when a noun was used as an adjective during your lessons? Adjectives as NounsIf nouns can serve as adjectives, then adjectives can also serve as nouns.The rich should help the poor.The words rich and poor are typically used as adjectives, but in this case, they are used to name entire groups of the population.Remember that nouns are naming words. The general rule is that, if you can put an article in front of an adjective, it functions as a noun.Double Function VerbsLearning to conjugate and use regular and irregular verbs in all sixteen tenses is quite a challenge.To make the situation more complicated, some verbs can be: both linking and action, transitive and intransitive, modal and auxiliary, depending on how they are used.This is a partial list of verbs that can be both linking and action:tastelikeappearbecomefeelCan you write a linking and action sentence for each one?You should also be aware that some verbs can be transitive or intransitive, depen ding on usage.Tony demonstrated his proficiency in business English.Cathy demonstrated at the protest.Which one is transitive? The best way to find out if a verb is transitive is to ask what? Or who?  after the subject-verb portion of the sentence.Now that we've learned all about double-function words, let's put them to use.UK, and Esl teachers around the world recommend that their students include Elements of Style in their English language study materials, alongside their dictionary and thesaurus.In those pages you will find guidelines for proper English that are not necessarily covered by any grammar rule. In spite of all the timeless style recommendations in that book,  there are some grammar rules you can break.Let us now test your overall knowledge of English grammar. Day Seven: The Best Grammar ExercisesAs you learn to speak English, you will find that understanding grammar will improve your ability to use the language.Every Verb Tense Conjugates Differently.Writing or speaki ng, especially using the negative form of any verb phrase can be complex, even more so if you are composing a sentence using an irregular verb.It pays to practise this aspect of grammar.On Sentence StructureTo speak English fluently, you should use short, concise sentences with as few adjectives and adverbs as possible.Word order rules can sometimes be complicated. To become fluent in English, you must internalise these edicts and use them in your spoken and written English.Proper Punctuation is VitalOddly enough, English courses seldom emphasise the importance of punctuation.Punctuation errors being so prevalent in the language, obviously English teaching should include in-depth instruction on how to use these marks effectively.Fortunately, if you are learning English online, you can find many sites that promote the proper use of punctuation.The University of Bristol  has such a page. It is loaded with practice exercises and quizzes that address punctuation.Using the Right WordThe trouble with English words is that so many of them sound exactly alike! Some of them are even spelled the same.Effect and affect is just such a word pair. One of them suggests a quality that expresses outward; the other is one that works inwardly.Affect is generally used as a verb.Effect can be either a noun or a verb, but is mainly used as a noun.To sharpen your vocabulary skills, you can test your vocabulary knowledge of the most frequently confused word pairs.The Best Grammar ExerciseThe best way to work your English language skills is to use them at every available opportunity.You should not concern yourself too much over whether any given word is a preposition, a conjunction or an abomination of the language.Our formula to achieve fluency: learn abundantly, speak frequently, and challenge yourself constantly.Learning English in daily doses will increase your language competence Source: Pixabay Credit: Emilian DanailaEnglish Learning in Daily DosesGrammar is a demonstration of t he complexity of the human mind; it is something that evolved as we evolved; it is a product of nature, not of culture. - Daniel EverettDuring native English speakers' early education, emphasis is placed on proper pronunciation, and reading and writing skills. Grammar learning happens as a matter of course.On the other hand, Non native English speakers delve deeply into grammar rules, sometimes at the cost of developing speaking skills and sacrificing pronunciation altogether.One does not need to understand fundamentals of electricity to enjoy its benefits. To learn English, you don't need to know whether a verb is transitive or intransitive in order to conjugate it and use it correctly.Maybe it is not necessary to know why some words serve more than one function in order to speak English properly.But, if you want a strong foundation for your English language skills, then your English learning must include knowledge of every aspect that binds it together.Learn English online with a private tutor from Superprof!

What To Do When Someone Steals Your Ideas - Introvert Whisperer

Introvert Whisperer / What To Do When Someone Steals Your Ideas - Introvert Whisperer What To Do When Someone Steals Your Ideas What do you do when someone you know steals your ideas? I have previously outlined things you can do to either prevent idea theft or to ensure your ideas are public enough for others to realize where they came from, to begin with. But, let’s go to the next step with this problem. Let’s say you’ve done all the right things to give your ideas visibility but the “Idea Thief” has still taken your idea and ran with it. What do you do then? I believe you have the following choices: Ignore them. Doing nothing is easy in that you don’t have to take any action and may allow you to get over it faster. Let the person know that the idea came from you and then step back. This approach takes the assumption the other person may not be aware of what they did and may do the right thing once they know of their error. Let the person know and ask them to stop. Much more confrontational and risks getting ugly. This sort of approach can have lingering effects of all sorts that you may not want to deal with. Let the person know, ask them to stop and take the next step. Taking the next step could be escalating to some form of management or even an attorney. Not an option or choice: Waging a “war of words” in social media. You hear this all the time. It never turns out good so I note this only because you will never have the potential for a good outcome. As you go through this list, the level of personal investment â€" especially emotional â€" increases exponentially. I believe you pursue a response that is proportionate to the impact or damage (or potential damage) it does to you. In other words, just because it makes you angry, doesn’t mean that the impact to you is all that great. I also don’t think you brush it off simply because you avoid confrontation. This is a situation where you may need to muster the courage to stand up for yourself. This is one time where I think you have to clear your head, let the emotion die down and then try as best you can to make a rational decision. I’d suggest you consult with one of your more levelheaded friends to help you sort it out. The good news:   This doesn’t happen very often so you may never face it. I hope that is your situation but if it does, you’ll now know what to do. A good defense is a good offense. Power-Influence-Office Politics: it comes down to your Strategic Relationships and understanding of how you build each one of these elements. I want to help you accelerate your career by connecting you with your Free Instant Access to my video that outlines all of this and meaningful actions you can take today!  Start watching now by clicking here!

Finding a Site to Download the AutoCAD Program

Finding a Site to Download the AutoCAD Program Where to  Find  AutoCAD   ChaptersA Brief Description of AutoCADWhat Are Some of the Benefits of Using AutoCAD?Where to Find AutoCAD“This is a software-powered world.” â€" Satya Nadella  The days  of textbooks, libraries, and encyclopedias are long gone.  Software systems have revolutionised  how things are learnt and done?in the workplace, at home, and in education.  Famous software developers such as Mark Zuckerberg and Bill Gates have made billions of US dollars developing modern-day systems that are used daily such as Facebook and Microsoft. Their inventions have made communication and access to knowledge more obtainable than ever before.  But what about technology and software systems in the workplace, has it really changed??  The developments in modern-day technology have skyrocketed since the 90s and employers and businesses have  welcomed the?efficiency of user-friendly software.  For professionals working in technical fields such as electricity, architecture, and graphic design a software system that was developed in the 80s is a  godsend.?  Which software is that??  AutoCAD. A computer-aided design software application that has been improved each year since its release in December 1982, AutoCAD has transformed the way technical projects are conducted.  In today’s article, we will briefly discuss  AutoCAD  and some of its features, such as rendering, prototyping, 3D modelling,  geometry sketch  creation,  and  building design.    AutoCAD  is  produced by  Autodesk, and users can create both 2D and 3D drawings that are used in construction and manufacturing.  AutoCAD is  compatible with both Microsoft and Mac products.  AutoCAD is  utilised  in the  mechanical, telecom, civil, and architectural engineering  fields. It is a  specialized piece of  software  and requires  time to  learn.  AutoCAD is used and  appreciated by professionals  to increase overall productivity, to improve the quality of the design, to create a database for manufacturing, and to improve communicatio n through documentation.  Before this software came into existence, engineers used drafters and sheets to draw designs of a product which was very time consuming, and to make matters worse, if the drawer or designer messed up and drafted a blueprint that was unsatisfactory to the client,  they had to start again from scratch.  Blueprints  to manufacture  engine valves and engine parts  are some of the most common?things created with AutoCAD. The fact that  AutoCAD  can be easily accessed from one portable computer to another makes it easier for all members of the design team to review or fix any potential issues before the manufacturing and assembling  process.  What Are Some of the Benefits of Using AutoCAD?Since there are pros and cons to everything in life, the following are some of the benefits of using AutoCAD in daily life:Users can create an impressively accurate CAD drawing or design;  The plans and drawings can be either in 2D or 3D format and can be rotated to get a better view of the finished product;  Other indispensable computer programs or software can be linked and used simultaneously to design and draw on the AutoCAD system;  AutoCAD  has introduced  features  to create, edit, and adjust  3D designs and 3D models  before the printing process;  Are you a designer looking to create your next masterpiece? Look no further because the AutoCAD program helps those working in the fashion industry with the design process when creating new  jewellery, dresses, or other top fashion sketches that will rule the runways come fashion week in the fall;  Architects love using the AutoCAD software to design, plan, execute, and test the strength of a building before the construction phase has started; highly recommended for budding architects looking to acquire  and complete the best building designs available in the world of architecture;  Industrial engineers face  pressure to design  objects that reduce manufacturing costs.  AutoCAD  accomplishes this task by replacing the long hours of manual designing. Also,  AutoCAD  allows  industrial engineers  to  thoroughly  analyse  sketches and troubleshoot potential issues before production.  When using AutoCAD software, users will praise its overall efficiency and practicality; before its utilisation, regular tasks were far more complicated.But, where does one find AutoCAD software for download?  Where to Find AutoCADAutoCAD software can be downloaded on Windows or Mac. (Source: Unsplash)While there are many different online resources that offer the AutoCAD software, the following are the best and help users start drafting and drawing ASAP:  Autodesk (UK):?Subscribe for a 3-year term and save 10% on AutoCAD.  Click here to purchase.  Autodesk (Australia):?Subscribe for a 3-year term and save 10% on AutoCAD.  Click here to purchase.Easy as pie, effectively setting up an account and downloading the AutoCAD software is a brilliant idea for professionals working in technical fields.

Volunteering at Pimlico Academy - Jessicas Story

Volunteering at Pimlico Academy - Jessica's Story I noticed tutor training being advertised on Tutorfair’s website, and as I wanted to gain more experience within the English school system I decided to attend the event. The training day was a full 8 hour long day. I learnt lots of different things throughout the day, but my main takeaways were the session on how to organize a lesson, and advice on the what to do if there was a case of child abuse, how to spot it, and my role as a childcare protector â€" which is different to the Spanish Education system. After I sorted out my DBS, I started at Pimlico Academy at the end of November, volunteering as a Spanish teaching assistant. I was warmly welcomed into the class as they were thankful to have some extra help, especially as I am Spanish! I soon grew very close to my students, I recognized where they were struggling and I helped push them to try their best as I could see their potential. The class teacher asked me to focus on helping the class improve fluency when speaking Spanish. A few of the students were a bit anxious at the beginning, I often heard “But I can’t speak Spanish” “I’m no good at Spanish!” when I heard this I told those students “I understand what you are going through as it’s hard for me too! I’m still learning English and picking up new things every day. It just takes time and lots of practice.” As I empathized with my students, and related to their daunting experience, it encouraged them to take more risks and they began speaking with more fluency. If they didn’t know a particular word or got a bit stuck, they knew they could just ask me! There was a particular student who caught my attention. She never wanted to participate in lessons and often complained of having a headache. I recognized that she was just feeling unsure of herself and her ability. I soon won her over, her confidence grew and she now actively takes part in Spanish lessons and looks as though she is enjoying herself. Another of my students confided that although she was great at Spanish last year, she felt as though she had forgotten everything over the summer and felt behind. With this little bit of one on one time in class, I was able to refresh her knowledge and get her up to speed. In my opinion her level is now much higher than the previous year. Most of the questions I was asked were based around vocabulary and grammar, and for this reason I tried to teach them lots of new verbs and new words in a fun and easy way! The Tutorfair volunteer experience was well worth while. I learnt more about the British school system, and I have walked away feeling more confident about my ability as a teacher and my teaching style. If you take part in the volunteer program you’ll receive an observation when teaching. Thanks to Felicity (my observer) who pointed out a few areas in which I could improve. Her advice has been invaluable to me, especially as I am just starting my career. The school and class teachers really appreciate the help I offered. They recognize how valuable it is for their students to be able to ask questions in class without holding up the rest of their peers. By Christmas I felt as though my class and I had developed a really close relationship. I am sure our bond will only grow stronger as we all get to know each other more over the next term. I really enjoy volunteering at Pimlico Academy, my favorite moment with my students was when they asked me where I had bought my jumper (which features a little dog on the front!). Even though this was a brief and possibly a trivial moment, it is these instances when you feel accepted and it showed me that they were interested in me as a person not just seeing me as their teaching assistant.

Chicago Math Tutoring Program Delivers Big Changes

Chicago Math Tutoring Program Delivers Big Changes Chicago Math Tutoring Program Delivers Big Changes Chicago Math Tutoring Program Delivers Big Changes March 23, 2015 At Edwin G. Foreman High School in Chicago earlier this year, Avery Huberts watched as Christophir Rangel and Iann Trigveros worked on a math problem. Photo by Whitten Sabbatini for The New York Times If you have ever questioned whether individualized, intensive tutoring and positive relationships can make a difference, Match Educations ground-breaking program in Chicago is more proof that its absolutely possible. A column in The New York Times spotlighted some of the incredible results achieved by the math program for 1,300 students in 12 public high schools. Developed by Match Education in Boston, which seeks to correct the “mismatch” in academic preparedness common among minority students in impoverished areas, the program provides two-on-one math tutoring for hour-long sessions every day. In the first year, on average, students who received Match tutoring and mentoring increased their math learning gains by 1 to 2 years more than the control group, and their test scores on the National Assessment of Educational Progress math exam reduced the black-white test score gap by a third. Furthermore, the tutoring also reduced math course failure rates by 50%, and overall course failure rates by 25%. By helping students in math every day, tutors are building students confidence so they are less likely to fail other classes or drop out of school, and also less likely to be arrested for violent crimes. According to the programs executive director Barbara Algarin, These students can make remarkable progress when they appreciate that their tutor is in their corner. The math connection leads to better study skills and a love of learning. Grades improve across the board. This column cites an issue that both HEART and Match address: It is difficult for teachers alone to provide the amount of individualized attention needed by students who are performing multiple years below grade level in math. Teachers must go back and re-teach a variety of critical math skills that were missed in previous years before their students can comprehend grade-level content. “Just a few years of this type of intervention could bring almost all students up to grade level,” said Jens Ludwig, a professor of social service administration at the University of Chicago and the director of its Crime Lab, in the New York Times report. “By then they can benefit from what’s being taught in regular classes and have real hope for a high school diploma.” This column also states that “American parents spend $7 billion annually on tutoring, in some cases as much as $400 an hour.” Match offers a relatively cheap solution: tutors earn $16,000 per year. To Mayor Rahm Emanuel, who plans to expand the program, the lesson is plain. “What this shows is, don’t ever throw the towel in on the kids,” the mayor said.
