The Various Types of Organic Chemistry Units

The Various Types of Organic Chemistry UnitsA molecular and molar mass spectrometer (MMLS) is a very important piece of equipment when taking an organic chemistry course. There are several types available that are specifically designed for your specific needs. The most common is the four-pass type which has a series of four detectors with a particle size of 10 microns. It can be used to detect a wide range of organic compounds including alkanes, carbonates, hydroxides, phosphates, carbides, nitrides, and sugars.A universal molecular spectroscopy detector is the one you will more commonly find. It includes four types and has a highly sensitive detector that can be used to detect anything from water molecules, two molecules of chromium, chlorine, bromine, iodine, and many more. It is the most widely used and has the best sensitivity.Moles also make up part of this unit and as you may know are essential in mass spectrometry. There are two basic types; gas and liquid. There are also infr ared units which have a lot of different features. This will depend on what your other equipment is for.Electronic scale detectors can help to avoid inaccuracies as well as help you do your measurements accurately. Electronic scale detectors are used for certain compounds. These include chromium, iodine, and halogens. There are also ionic flow type detectors, fluorescence type detectors, as well as electrospray type detectors.A basic molecular scale includes a more rigid body, which is what makes it more reliable and accurate compared to the electronic or fluid ones. You will find that most electronic scale detectors use multi metallic ions. The technology is still a lot newer and not as widely used, so some of the features will not be as accurate as what the chemical industry requires.To sum it up, there are many different types available. The most common are gas, liquid, and multi-particle type detectors. They all have different functions but in the end they all serve the same pur pose. They are used for detecting different things, which means they each have their own advantages and disadvantages.There are also various types of chemical reactions that can be detected with these detectors. Inorganic reactions which may be seen with two metals may not be seen with everything else. There are many other uses as well.

Your Secret Power will Influence others

Introvert Whisperer / Your Secret Power will Influence others How to Use Your Secret Power to Influence Others at Work Check out our video on Office Politics I think by this point we all know Introvert’s tendency toward quiet.  Susan Cain titled her book on Introverts that way.  Yes, we can clam up in meetings and cocktail parties, which may or may not help our climb up the ladder. We don’t like to schmooze as small talk can be annoying and without purpose.  Creating relationships in an ocean of people isn’t something we like to do. That gets us to what we do like to do and one of those is definitely the Secret Power of Introverts.  Wait and look around to make sure no one is reading over your shoulder so we can keep this a secret.  Secret: We prefer to build relationships one-on-one in a more intimate setting. You might ask why this is a secret power.  Glad you asked. You build influence with others when you get to know them.  You can get more details about what is important to others when in a safer, more intimate setting.  When you know what is important to others you can be more supportive which builds influence.  Save it say, when anyone is in a group setting, the interactions are superficial at best, which is not a great way to get to know someone.  Advice like “work the room” completely misses the point in relationship building. In order to really get to know someone you have to focus on one person. Your best opportunities and support come from people who know, like and trust you.

Where to find honest reviews for online English teaching companies

Where to find honest reviews for online English teaching companies If you’ve spent any time at all researching online English teaching jobs, you will be alarmed at how fake some of these sites look. It’s not uncommon for a stock image of a man in headphones to take up 90% of the screen and for the other 10% of the screen to be occupied by Chinese characters. There’s really nothing more disconcerting than having to google translate job requirements for an online English teaching position. Often, websites for these online teaching companies offer scant information about the position. And when there is information, it’s generally just a list of qualifications/requirements for candidates. To find out anything at all about the actual job, you’re expected to send an email to what may look like a spammy email address. And even when the email address seems professional, it may feel like a headache to actually get in touch with these folk, only to find out it will be a 2 hour per week contract paying you $8 in total. Our advice is not to let bad web design, a lack of details or poor translation put you off. There are other places you can go to find out all the information you need to make the decision. The internet is home to a literal army of online English teachers in the exact same position. They are continually posting reviews, recommendations and advice for teachers in the same boat. All you’ve got to do is know where to look. You’d be surprised at how many of these dodgy-looking sites are actually legit. Like other careers, there are no shortcuts when it comes to a proper job hunt. You’re going to have to commit a few hours to figuring out what’s what in the online English teaching universe and reading up on the various online English teaching companies. There’s no easy way around it and to skip this step might land you locked into a contract with poor conditions and missed pay slips. This shouldn’t be the case, if you do your research, there’s no reason why online teaching won’t be as convenient and lucrative as it sounds. The best places to find trustworthy online ESL teaching reviews 1. Glassdoor Not all the online teaching companies will have reviews listed here (in fact, not many will have a presence on this site), but it’s generally a good place to start your search. They typically have detailed reviews as the process requires users to answer specific questions. 2. Google is your BAE The online English teaching companies should be all over Google, so it’s worth doing a thorough search on them. This will throw all sorts of listings and we recommend looking further than just page one. Tabs are there for a reason, so use them. If you take anything away from this blog post, it’s this: search, sigh, and then, search again. 3. REDDIT Online teachers are on the tech-savvy end of things and there’s only one place that all tech types seek information. Reddit might seem like a monster, but it’s chock-full of teachers answering questions about various online teaching companies, including VIPKID. There are subreddits that will answer your every concern. The internet is a helpful place, so use it. We recommend checking out the subreddit dedicated to online TEFL teachers. 3. Quora This is better than any review site. Chances are any company you’re wondering about has already been mentioned in the numerous questions posted by online TEFL teachers every day. But if you don’t feel like trawling through other people’s queries, why not post your own question. Quora will let you do it on a specific thread and select people to ask the question to. Just searching “teach English online companies” will throw up questions and answers that might already offer plenty of honest feedback about the companies you’re wondering about. 4. Facebook groups If you really want the honest truth about an online ESL company - avoid their company Facebook and jump straight to one of these groups. You’ll bypass all the nonsense. There will be more than enough people willing to give you their opinions about companies and conditions. We recommend the following: Hired online teachers with job reviews, Teach ESL online Online English teachers These are all full of teachers chatting about their positions. Now, I know what you’re thinking - anyone can write reviews on the internet and employees are probably penning odes to their own companies. But it’s pretty easy to spot a fake review and there are as many honest ones out there. So before I tell you where to search for reviews, I’m going to show you how to spot the fake ones peppering those very same pages. Sign up to Teach Away today for access to the latest teaching jobs around the world. How to spot a fake teaching English online job review Someone writing a fake review often seems vague They will list benefits and not go into much detail. This is because it’s hard to say much about something you haven’t actually experienced. Honest reviews for online teaching jobs usually focus on the details of the role because they’ve been in your shoes and know what people looking at reviews need to know. Honest reviewers tend to be specific about their own experiences and qualifications as well as giving thorough examples of working with the company. It sounds weirdly sales-y Use your common sense, the minute you feel like you’re being sold the online job, back right up and have another google. It’s not to say that a fake review is lying, just that what you want is a little more insight than a sales pitch. It’s all about the reviewer The more you see the words “I” and “me” the warier you should be. Psychologists have found that when people are lying - they tend to try and make their experiences seem more personal. A real reviewer will mention themselves, but perhaps in passing, their review will most likely focus on the role and company. The same review is cross-published on numerous sites This one is easy to spot, and if you see the exact same answers cropping up over and over… with the same wording, then it’s probably a copy and paste hack-job. Verbs versus nouns Honest people tend to have some cold-hard facts and their reviews will be full of nouns, so do a little count. Fake reviews are heavy on the verbs as they try to get you to believe their drastic sounding stories. Check the timestamps on reviews If all the good reviews are written at pretty much the same time… be warned! I’m sure there’s some universe where every online teacher logs on at the same time feeling like passionately sharing the positives of the company they work for…but we’re not in that universe. Generally speaking, real reviews will be spaced out. A concentration of reviews for a particular company during office working hours on one particular day in June of 2018 might be a good reason to get suspicious. Review the reviewer ???? Most honest reviewers come with a profile attached. Have a nosey…do they answer similar questions on the site and are the answers genuinely helpful. If it’s on a social network, it’s easy to see if they’re a real person and you can double check LinkedIn to make sure they’ve actually been a teacher. Not everyone has a big online footprint, but it’s not hard to find out a little bit more about the person writing it if you take a minute to look. The review is sloppy People being paid to post fake reviews aren’t paid a lot and usually per review. This means their reviews can leave a lot to be desired and if you’re seeing terrible punctuation, poor spelling and just plain bad English...well ask yourself this - is this person really an English teacher? I don’t know any English teacher worth their salt that would leave a trail of typos in their wake!

How To Squeeze The Most Out Of Your Internship Experience

How To Squeeze The Most Out Of Your Internship Experience image via www.adweek.com Internships are a lot of work, especially on top of school and another job or two, but once in a while, really stop and ask yourself if you are getting the most out of that internship as you can. How can you do this exactly? Let’s take a look. Get in with the in crowd: Internships usually mean that you get to work with some pretty cool people in your field or industry. Whether this is a professor who has a lot of experience or a working professional that you aspire to be, you really want to be around them as much as you can and soak in their awesomeness. Sure, you are going to be doing a lot of brunt work and you can’t always be at the cool table, but sometimes you get to snag a spot, and you don’t want to waste the moment. For my creative writing internship, all of the interns had to help put on a Living Writers Series, where authors would come to our school, read from their books or poetry, and then host a QA. We had the opportunity to go to dinner with a few of them, and I got to tag along with Chang-Rae Lee, and he actually asked me about my own writing! I was so star struck and amazed that this successful author was taking the time to ask about little old me. It was such an amazing opportunity, and I wouldn’t have had the chance to be there if it weren’t for my internship. Moments like this have to be earned through hard work, so if you prove your worth, you might just get an in with the in crowd. Do you know how valuable that is in today’s society where everything is based off of connections? Watch the people you work with and for; they might just know someone somewhere who will help land you your dream job someday if you play your cards right. Take on extra work: During your internship, you probably won’t be the only intern that is bustling around, so try and really make sure that you stand out. Take on extra work when there is an opportunity to do so, put a lot of effort into everything that you do, don’t be afraid to ask questions or get clarifications to make sure that you are doing things right, and really show that you are grateful for the opportunity that you have and you won’t put it to waste. You want to leave your internship with the company begging you to stay on as an employee, or if they don’t have the room, at least leave in a way that will make them remember you and that will result in you getting some awesome reviews and letters of rec. Bond with other interns: All of you interns are in the same boat and same position, and while it may not seem “cool” or optimal to get all buddy-buddy with people that you have to work with, you never know when the connections might come in handy, or what friendships might be born. This doesn’t mean you have to be best friends with all of the interns, but if you take the time to get to know them, your future might just thank you for it. Students love helping each other out, especially when it’s about scoring an awesome job, so do good now and good will come to you later. unsplash.com Be quick on your feet: A lot of internships require you to dive in and sort of learn as you go. You might get a bit of training, but after that, you are expected to get your work done and figure it out, and also ask questions if you get lost. This is really valuable for when you go and get your job in the future, because your degree will give you the knowledge to work there, but you might not have all the skills under your belt yet. You’ll have to learn as you go, be quick on your feet, and show that you can watch and learn quickly. You can talk about this during a job interview, and prove that you are the right one to hire because you learned how to pick things up quickly during your internship. These are just a few ways to really squeeze everything you can out of your internship experience. Definitely make sure to get at least one or two of them under your belt before you graduate, to boost that resume and your confidence in the field.

E-Learning Futuristic Education Resources for Today and Ideas for Tomorrow

E-Learning Futuristic Education Resources for Today and Ideas for Tomorrow This article  discusses ideas for integrating new technology with education, what the future may hold for education, and real high-tech resources for students and educators. Smart Phones and Tutoring? The smart phone…screen size may present problems for students. Most students require a lot of room to perform mathematical calculations. Perhaps they could write on a tablet at home/school, then save a reduced copy of it on their phone for later study purposes. The phone should have a vertical and horizontal scrolling type feature to enable them to go back and review or edit previous work in a connected fashion. Concept mapping is a very useful teaching tool in many subjects and also requires this type of navigation. Voice recognition would be a great way to handle the notation for mathematics. I’m not aware if there is such software available yet, but if not, it may be soon. Speaker phone is nice for conversation, but a closer microphone (less interference) might be needed for voice recognition of symbols. It will save so much time, and verbalizing concepts is a productive element for the teaching and learning process as well. If the instructional device could interface with the students’ PD, then they would be totally free to think without worrying about taking notes, etc. They could manipulate these notes on their own PD to arrange them according to their personal learning style. Students think about things in so many different ways. Enabling them to interact with the concepts personally is very important. In the schools (and maybe even in the home) there may be a problem with the applicability of the smart phone if it was not in some way a “secured” learning environment. There should be a way to ensure that students are engaged in learning â€" which could be argued is always the case, no matter what they are doing. I’m personally not a advocate of censorship, but as a teacher, I have noticed that distractions to the learning process have become a very real issue since cell phones. It’s not that I’m bothered so much by distractions (they can be valuable at times) it’s just that many students do not, for whatever reason, decide to use their time effectively. It’s frustrating to see very intelligent young people “wasting their time” on “net junk”… things that may not benefit them in the future. I’m aware of screen monitoring systems, but they require the attention of the instructor whose time is much better spent teaching students. What is needed is a semi-close d system that affords the child room to explore, but also blocks irrelevant interference. In a perfect world, students will learn that they control the technology and their ability to learn from it. It should not control them, or draw them away from opportunities to learn and advance intellectually. The structure of the environment is extremely important. Negative Aspects of E-learning Regarding security and technology, let me give you a personal example of possible negative aspects “e-learning”. One of my wealthy friends sends her children to an exclusive private school where laptops are issued on enrollment. She thought that by doing this she was giving her child the very best. The school had preloaded certain educational software for the students, so she thought he had to work on that particular computer, and since they didn’t have administrative rights, they could not install anything. Without her knowledge, her preteen son became involved with some very scary, unsavory folks during times that she thought he was working on his schoolwork. It will take a very long time for their family to get over this incident â€" the child’s personal information is also out there. These things should not happen. The school proceeded with their laptop initiative without anticipating problems. Future Hopes for Education Technology and education will soon become mutually interdependent. Each person will need to learn how to use technology to improve their education and expand opportunities for the future. I would like to see the development of community-based technology learning centers (for lack of a better term right now) to connect community resources, families and schools to achieve this level of learning. [Honestly, Im afraid that the schools, with a slow-paced institutionalized approach, cannot respond appropriately to our needs] These centers could provide quality technical support to the schools, information and training for parents, students, and teachers. They could bridge the gap between the home and different levels of schooling. [This gap seems to widen as children get older and access to technology increases. This is the exact opposite of what should be occurring. Parents should be empowered to guide their own children.] Staffed with educational technology personnel, assisting the devel opment of more effective tools for the teaching and learning process. This would be a community-based forum for collaboration, innovation, and technical support. A bank of “best lessons” could be available for teachers or homeschoolers to practice with and/or use in teaching. These centers could also serve as e-learning satellites for distance learning projects as we discussed earlier. Like the public library system began years ago, these centers could inject an educational technology renaissance now. I hope to see many changes happening in education in the very near future. Our children are depending on us. Resources Smartboard, Smart Technologies (https://smarttech.com) Complements As high school teacher who uses a SMART board, from SMART technologies, in the classroom I think it offers a great platform for interaction between students and their teacher. My district has three high schools, so the SMART board technology has been extremely useful for me to communicate with other mathematics teachers at the other buildings. It’s nice to just be able to write the symbols, and not have to try to type everything up to email it. I think that there is a lot of potential for teachers and students in e-learning environments to communicate more effectively with a SMART board. Criticism I found myself flipping back and forth between screens when I first started using the SMART board. Students had it all right their on their paper and tried to be patient with me as I fumbled around. What is GeoGebra? (https://www.geogebra.org/cms/) GeoGebra is a dynamic mathematics software for education in secondary schools that joins geometry, algebra and calculus. On the one hand, GeoGebra is a dynamic geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice-versa.

Saint Valentines Day, Interesting Facts for Knowledge Lovers

Saint Valentines Day, Interesting Facts for Knowledge Lovers Saint Valentines Day, observed on February 14 each year, is a fascinating festival of romantic love, when people show appreciation for their loved ones and friends. The celebration of the Feast of Saint Valentine is commonly accompanied with symbols of love, hearts, red roses, images and models of Cupid. On Valentine’s Day lovers, family members and friends exchange greeting cards, letters, flowers, chocolates and other gifts, arrange romantic meals or weekend breaks. People who have romantic feelings for somebody often use the occasion to make this known. Valentines Day is also a popular date for getting engaged and for weddings. Valentines Day is celebrated  with great fervor in many countries around the world, even though it is not a state recognized holiday and remains a working day in most of them. It  is the second most celebrated holiday around the world after New Year’s Day and the second-largest holiday for giving greeting cards, after Christmas. Traditions related with this holiday vary from country to country but everywhere the day is focused on romance, love, appreciation and friendship. However, romantic atmosphere is not the only one virtue of Saint Valentines Day. It is also featured with an interesting historical background. The origins of this joyful holiday are rather vague and gloomy. There are many theories but the most popular of them claims that Valentines Day evolved from the story of Saint Valentine, who was a Roman priest during the reign of Claudius II. Claudius prohibited marriage during wartime  because single men were better soldiers. Valentine disobeyed  the Emperor  and performed secret wedding ceremonies. For this, he was jailed and then martyred  around February 14 in the year 270 CE. According to legend, being in jail, Valentine wrote a love note to the jailors daughter with whom he had fallen in love. He signed his letter: From your Valentine. So it was St. Valentine himself who sent the first valentine. In fact, there were at least three different Saint Valentines throughout history: one was a priest, another one a bishop and one more is just known for being a martyr. The priest’s and bishop’s stories are so closely related that it is difficult to tell which St. Valentine the holiday is named after. The church used the day of St Valentine’s martyrdom to Christianize the old Roman Lupercalia, an ancient fertility festival held around the middle of February. On the eve of Lupercalia, young unmarried men draw names of young women in a lottery and they were paired off for the next year. Ancient Romans believed that birds also chose their mates on February 14th. In 496 A.D., Pope Gelasius assigned February 14 to honor St. Valentine in order to disassociate this date with the Lupercalia festival. Unlike the ancient tradition, the Christian church replaced girls’ names by saints’ names and the participant was supposed to model his life after the saint whose name he drew from the box. However, in the Middle Ages the girls’ names got back again and young people started to draw names from a bowl to see who their valentines would be. Eventually St. Valentine’s Day became associated with romance, exchanging love notes, presentation of flowers and confections. Valentine cards were always a very popular part of  the Valentines Day celebrations. Traditionally, lovers exchanged handwritten valentines. The oldest surviving valentine was written by Charles, the Duke of Orleans, who sent it on Valentines Day to his wife after being captured in 1415. In the seventeenth century a new sophisticated variant of Valentine cards True Love Knots â€" became extremely popular in the U.S. and England. These Valentines were drawn as a knot and were readable from any line and still made sense. Commercial cards appeared in the mid-19th century, when the interest in Valentines Day started to grow rapidly. Early versions of these cards were fashioned of satin and lace and ornamented with flowers, ribbons, and images of cupids or birds. Today, about 1 billion Valentine cards are exchanged in the U.S. each year. Interestingly, the most Valentines Day cards are given to teachers. Statistically,  teachers receive more Valentine cards than kids, mothers, wives, sweethearts and pets. The fact, that students use this romantic holiday as an opportunity to express their gratitude to those people who are planting the seeds of knowledge into their young minds, gives grounds for considering Saint Valentines Day also a day of a Love for Learning. So, don’t forget to send a greeting card to your favorite tutor. Happy Valentines Day!

Organic Chemistry Tutor - Rotational Energy

Organic Chemistry Tutor - Rotational EnergyRotational energy is one of the important concepts in organic chemistry. A rotary device is simply a material that has an ability to move. Many times it can move in three dimensions. In other words, it can rotate in one direction but not the other directions.Since rotational energy is so prevalent in organic chemistry, and it involves the molecules, it makes sense that the organic chemistry tutor would cover this concept thoroughly. However, there are many different concepts in organic chemistry, so there is no way you could cover everything in one short lesson.Therefore, the organic chemistry tutor will generally guide students through a lecture format that is focused on one or two concepts that they are most familiar with. After this lecture, the tutor will introduce their topics. By the time they have covered several topics, the organic chemistry tutor will introduce another topic for the student to review.The organic chemistry tutor will also use different ways to help their students learn the concept of rotational energy. The most common form of this is to actually show examples of rotational energy from the lab. One example of this would be showing students something like a rotor device, or if they wanted to see it in action they could watch someone build a rotor device. This example should not be too hard to understand, because rotors are often used in machinery to rotate the parts.Another way that the organic chemistry tutor could be used would be to direct students towards new concepts. Some people may not understand how rotational energy could be created or transformed, so a tutor could help them understand it. They could also show examples of how rotational energy was used to create chemical reactions in the laboratory.So if you find that your organic chemistry teacher is not doing a good job in introducing concepts or showing examples, then try looking for an organic chemistry tutor online. They will be muc h more than an old friend who knows about organic chemistry, they will have a wealth of knowledge and will be able to give you tips and tricks on how to best improve your organic chemistry.The organic chemistry tutor will be able to show you various ways of converting rotational energy into mechanical energy in order to move the molecules. With the right tutor you will be able to solve organic chemistry problems quickly and easily.
