What Do You Need to Know About Nucleophilic Sites in the Chemistry Tutor?

What Do You Need to Know About Nucleophilic Sites in the Chemistry Tutor?What do you need to know about nucleophilic sites in the chemistry tutor? Here's a basic introduction. A nucleophile site is a chemical element that contains two electrons, one of which has an extra 'ground' electron. The nucleus of a nucleophile is open to the normal flow of positively charged nucleons but the negatively charged electrostatic charges within the molecular framework of the nucleophile are offset by this extra 'ground' electron, resulting in the nucleophile attracting positively charged nucleons from surrounding molecules.The existence of these sites was first observed in molecules such as those containing hydrogen and nitrogen, or when a strong base or an electronegative electron-pair of the nucleophile was added to a neutral base. It is not known why the nucleophile was seen to be negatively charged, but many nucleophilic sites that have been found are ionic and their presence is in the left and right hands of the DNA double helix.It is well known that water acts as a nucleophile; so do a lot of other molecules. Water in its liquid state behaves like a single proton, with two protons each located in the same position as the water molecule. In fact water is said to be a nucleophile because it will react positively with an alkaline. Hydrogen, on the other hand, reacts negatively with water.But why would one expect from one molecule to react differently with another than one would expect to react with itself? If one were to make a molecule out of water, it would be expected to react with a pH-neutral base, which is not exactly the case. This is an important point: even though water is a nucleophile, this does not necessarily mean that it will react positively with an alkaline - the hydrogen and oxygen molecules within the water molecule have an affinity for the adjacent acidic molecules, creating a strong positive charge around the water molecule, leaving it open to react wit h a neutral.It is important to realize that any nucleophile, including water, has a stronger affinity for negative bases, making it less likely that an alkaline base will attack the nucleophile. This means that alkaline bases (such as sulfuric acid) are less likely to attack the nucleophile.So what do we know about the nucleophile? We know that there are very few nucleophilic sites in nature, and that most are in the left and right hands of the DNA double helix. We also know that natural DNA strands often have 'proto-nucleophiles' or so-called 'facilitated nucleophiles' that are the same as the nucleophile but with a different structure.One very important thing to remember about nucleophilic sites in the chemistry tutor is that, although they are often thought of as having a certain kind of 'site disadvantage,' there are actually many sites that could have a very different chemistry. For example, the nucleophile in the case of the H+ ion in the chlorine atom in the molecule (hydroge n chloride) is always neutral. There are no beneficial sites for the H+ ion (whereas the neutral site in the case of the H- ion (hydrogen chloride) is much more helpful. In the case of the chemical hydrogen, the H+ ion is much more strongly opposed by the phosphate group of the DNA molecule, and in the case of chlorine the hydrogen ion is more strongly negatively charged, so that the water molecule will react with the water molecule, resulting in a change in the water molecule structure.

Online Scientific Notation Converter Tutors

Online Scientific Notation Converter Tutors Scientific notation is a way to represent very large number and very small numbers. Scientific notation is a very useful notation to represent many numbers. The decimal point is placed such that there is one non-zero digit to the left of the decimal. The exponent of 10 is decided by the number of decimal spaces the numbers has moved from the originally given number. The sign of the exponent is decided depending on the given number. If the number is less than one then the exponent of 10 is negative. If the number is greater than one then the exponent of 10 is positive. Example 1: Convert the number 5,670,000 to scientific notation form regular notation? Solution: Given is the number 5,670,000 which is a number greater than one. The number can be written with a decimal point such that there is one digit to the left. Moving the decimal point 6 spaces gives 5.67 and the exponent of 10 as 6. This gives 5,670,000 number is equal to 5.67 * 106. Hence the scientific notation is 5.67 * 106. Example 2: Convert the number 0.000345 to scientific notation form regular notation? Solution: Given is the number 0.000345 which is a number lesser than one. The number can be written with a decimal point such that there is one digit to the left. Moving the decimal point 4 spaces gives 3.45 and the exponent of 10 as -4. This gives 0.000345 number is equal to 3.45 * 10-4. Hence the scientific notation is 3.45 * 10-4.

What is a College Seminar

What is a College Seminar During college, you may encounter a specific type of course format: the seminar. College seminar courses are typically small, and are generally led by a professor. They are often higher-level classes that focus on a specialized subject area in a given major or minor. Students are expected to participate regularly in college seminars, including giving presentations and participating in discussions. There are many ways that students can succeed in a college seminar course, including emphasizing their participation, remaining distraction-free, and actively listening during class sessions. Keep reading to learn more about college seminars: Which majors rely on college seminar courses? Any major can offer a seminar course, but some specializations lend themselves more readily to this format. Others may lean toward classes that utilize lectures. You may encounter a seminar in: A language course A literature course A philosophy course And others. Higher-level courses are often focused on discussion and investigation, rather than simple mastery of information and skills. In such instances, a seminar class is particularly useful.

Learn the History of Embroidery

Learn the History of Embroidery A Beginner’s Introduction on the History of Embroidery ChaptersEmbroidery Designs Throughout History Starting in The Bronze AgeIron Age and Dark Age EmbroideryEmbroidery Stitches for Medieval TapestriesEmbroidery History In Gold and WhiteTudor Embroidery FlowersThe 19th Century of Embroidery to the PresentSince the beginning of time, people have adorned their clothing with fancy needlework and hand embroidery. Be it by sewing shells on a shirt, cutting out patterns in leather skirts, sewing gold and precious stones onto a dress or adding a needle-woven border to simple linen shifts, early civilisations found many ways to embellish their clothing. It is therefore rather surprising to find that the art of embroidery can’t be traced back earlier than about 600 BC. This may in part be due to the fact that very few early textiles have survived. And of those that have, not all have been examined by textile specialists. For example, early Egyptian fabric was often marked with hieroglyphs mentioning the owner or the quality. What is unclear is whether these marks were needle-stitched or woven directly into the cloth, as woven bands and even repeated woven designs are known from some Egyptian textile finds of the period from about 1340 BC.Looking for sewing courses London?5th century BC. In Bronze Age Scandinavia, stem stitch and various twined and buttonhole stitches were used to embellish clothes.Learn how to embroider with our beginner tutorial...Iron Age and Dark Age EmbroideryIn the 5th/6th centuries AD, when Egypt was part of the Byzantine Empire, the festive, wide tunics of the period were decorated with roundels and panels. Most of these decorative strips with their marine and pastoral designs were woven in a technique similar to Jacquard weaving. But a few roundels have survived in split, stem, and chain stitch. Like later Dark Age examples where line stitches were used to fill out forms, the outline of the figures was stitched first, with the embroidery continuing in an inwards spiral until the section was fille d. Chain stitch is a technique we find again in later Dark Age textiles; in the 7th century, the burial garment of the Merovingian Queen Bathilda  used chain stitch to imitate her precious jewellery - as she retreated to the Abbey of Chelles at the end of her life, she had probably left the real jewellery behind or donated it to the abbey. In honour of her queenly status, the simple white shift she was buried in was stitched with rows of necklaces and several brooches. The 10th century embroideries from Mammen in Denmark used stem stitch and herringbone stitch for animal figures and bands depicting acanthus leaves and human faces. Though they are too fragmentary to know for sure, they probably decorated a cloak or tunic.Also discover how you can get started in embroidery...Crafting Goldwork in the Dark AgesGold has long fascinated mankind with its rich sheen and its failure to oxidise. They found ways to wear it - making it into jewellery, and eventually adding an embroidered gold f inishing it onto their clothes. Gold thread were generally couched into place with wool and later silk thread as it can’t be sewn in the traditional sense. Though gold was probably incorporated into clothing at a much earlier date, one of the earliest confirmed use of gold embroidery is from the tomb of Merovingian Queen Arnegunde of the 6th century BC. Her outer garment had goldwork embroidery cuffs in a rosette design .Goldwork from the sleeve cuffs of Queen Arnegunde. Die Franken: Wegbereiter Europas. Exhibition Cataloguie. Mainz: von Zabern, 1996.A small fragment from the late 8th to early 9th centuries from Maaseik, Belgium uses surface couching for gold threads and split stitch on the backgrounds - a precursor to the Opus Anglicanum of the medieval period. The stole and maniple of St. Cuthbert used stem stitch for the outline and, again, split stitch for filling in the figures. The gold thread for the background was held in place with simple couching.Discover how you can lea rn to sew with easy embroidery patterns!single stitches are laid crosswise and couched. Bayeux stitch is commonly referred to as laid and couched work; in Scandinavia, where it probably originated, it is called Refilsaum.KlosterstitchIn the cloisters of Northern Germany, nuns made elaborate wall hangings for the choirs of their church in a special couched stitch known as Klosterstich, “cloister stitch”. In the 13th-16th centuries, the monasteries of Lüne, Ebstorf, Heiningen and Wienhausen produced beautiful tapestries in brilliant colours depicting biblical and allegorical scenes and scenes from popular novels of the period (Ywain, Tristan). Though now Klosterstich has survived almost exclusively from Northern Germany, a few examples from southern Germany suggest it was more common than the evidence suggests - it is possible that there it was mostly produced in a secular context. Klosterstich is a self-couching technique - that is, the thread laid down is the same as the thread used for couching. Klosterstich is worked with vertical laid stitches. They are set from top to bottom and couched from bottom to top. In Klosterstich the couching stitches are practically invisible, separating it from similar techniques such as bokhara stitch, where the couching stitches make patterns atop the base embroidery. Roumanian stitch is also similar, but is worked horizontally rather than vertically.German Brick StitchGerman brick stitch is a counted-stitch embroidery technique using a variation of brick stitch somewhat reminiscent of bargello. Where brick stitch only uses stitches of the same length, medieval German brick stitch will sometimes use up to three different lengths to make the pattern. It was popular in the 14th and 15th centuriesBrick stitch often uses colourful geometric patterns in counted stitch. Photo credit: Catrijn on Visual hunt / CC BY-NC-NDThe most common form is a recurring geometric pattern covering an entire surface.

But just because they were white didn’t mean they weren’t decorated: starting from the 12th century, whitework altar cloths have survived using a variety of stitches including stem stitch, chain stitch, long-armed cross-stitch, buttonhole stitch, brick stitch and a variety of openwork techniques. In harmony with the theme of Lent, they depicted the death and resu rrection of Christ.Opus AnglicanumThe Middle Ages brought for several goldwork techniques, including or nué (a couching technique with amazingly subtle shading) used from the 15th century onwards. But the most common was the so-called Opus Anglicanum. The term was coined in the 13th century for a technique that existed long before - the same we have already seen for the 8th/9th century Maaseik embroideries. English embroiderers were famous for their ecclesiastical vestments in gold and silk, so that anything in that technique was called “English work”. In a secular context, small bags and pouches showing lovers or scenes from medieval novels have also survived in Opus Anglicanum.Opus anglicanum was used for religious garments such as this cope. English goldwork was famous throughout Europe. 27.162.1Metropolitan museum of Art / CC0 1.0The coloured part of the embroidery is done in split stitch, with the gold couched in place.Learn more about embroidery by joining a sewing class near you.

English Embroidered Bookbindings by Cyril James Humphries Davenport, F. S. A,. edited by Alfred Pollard, London, 1899BlackworkThough black embroidery was known in England before that, the introduction of blackwork to the English court is credited to Catherine of Aragon who supposedly brought it over from her native Spain when she married King Henry VIII in 1509.

The embroidering lady is an enduring image of the 19th century, and indeed, many of the embroidering techniques popular today were used at that time. Various articles of daily life were embroidere d, from fireplace screens to footstools to doilies and “tidies”, to little bags and huswifs (needle rolls). As over the course of the 20th century machine embroidery became easier and embroidery was no longer the fashionable embellishment of choice for clothing, it became purely a hobby while at the same time ascending to an art form, with embroidered images being created solely for the joy of owning them.Ready to start sewing?

Screen Use after Bedtime and ADHD

Screen Use after Bedtime and ADHD With phones, tablets, and video game consoles accessible to kids just about any time and anywhere, setting limits around screen time is more challenging than ever. When ADHD is added into the mix, setting screen time limits becomes even harder. Kids and teens with ADHD are more likely to use screens excessively, become argumentative when limits are put into place, and have a harder time sticking to the limits and resisting the impulse to use their devices when theyre supposed to be doing other things. While research shows that screen time and video games dont cause ADHD, under certain circumstances, too much screen time does make ADHD symptoms worse. The biggest culprit for many kids and teens with ADHD is sacrificing sleep to get more screen time! Sleep is essential for regulating emotions, staying focused, and making good decisions. So, when a child or teen has ADHD, their ADHD symptoms are much worse when they arent sleeping enough. Unfortunately, having ADHD can make getting a good nights sleep a struggle. In fact, studies show that up to 70% of kids and teens with ADHD have ongoing sleep problems. One of the biggest culprits influencing sleep problems among kids with ADHD is screen time. Theres a great deal of research showing that using screens right before bed leads to poorer sleep in kids and teens with and without ADHD. But even more problematic for many kids with ADHD is the time they spend on screens after bedtime, when they should be sleeping instead. In a recent study of nighttime media use, researchers surveyed 81 teens with ADHD about their sleep habits and media use after 9pm.1 Study results showed that almost all participants had a cell phone in their room, and 50% also had other devices (e.g. tablet, TV). 80% of the participants reported spending more than two hours using their devices after 9pm. Screen time after 9pm was associated with more sleep problems and more symptoms of anxiety and depression in teens with ADHD. And the majority of the teens in the study were getting far less than the recommended number of hours of sleep each night. What can parents do to help limit screen use after bedtime? Well, prevention is really the only effective strategy. After all, parents cannot physically monitor their child or teens screen time when they are asleep themselves. In practice, the most effective strategies that Ive seen work are keeping all digital devices out of the child or teens room (including a television), using cell phone monitoring and control tools to restrict use after the bedtime hour, turning off household (or teen) internet access after bedtime, and using a device monitoring app to check the childs usage and ensure that they are in fact sticking to the screen limits. The biggest challenge to using these strategies at home comes from the kids and teens. Most will complain (convincingly!) that they cannot fall asleep if they are not using their device in some way they will say that they need to watch TV or videos to fall asleep, need to listen to music on their device, or need to use a white noise app on their phone or tablet. Parents need to resist giving in and look for alternative solutions to help their child or teen fall asleep. For example, a white noise machine can be purchased to replace a white noise app. A simple screen-free Mp3 player can be used to replace music on a phone or tablet. Books can be used in place of videos if they need something to quiet their mind before bed. Your child or teen isnt going to be enthusiastic about any of these alternatives, because what they really want is to have their device back! But the bedtime limits really are in the best interest of the child or teen, and their disappointment is a small price to pa y for better sleep, better ADHD symptom management, and potentially fewer symptoms of anxiety and depression. If parents are able to stick to the limits, after a while, their child or teen will adjust to their new routine, the complaints will die down, and they should be sleeping better. If sleep problems persist, consider talking to your childs pediatrician. There are many ways to treat sleep problems, and the pediatrician will help you find the right solution. 1Becker, S.P.

What Not to Do When Applying for Scholarships

What Not to Do When Applying for Scholarships Photo courtesy of pixabay.com If you want to earn a little extra cash to pay off that hefty college tuition, scholarships are a great way to do it. The problem is, they are the method most people go for when trying to offset costs. If you want to make sure you get the money over others, take a look at the mistakes many other people make when applying. Then, make sure you dont do the same! Heres what not to do: 1. Be bland and give up early There are many ways to win scholarships, you just have to motivate yourself to be continuously looking and to complete the applications. While private scholarships are common (think: hometown organizations), there are many school and federal scholarships as well. Dont count these out. They can be great additions if the private scholarships get taken. With fewer people thinking about these options, fewer people will apply, giving you a better chance for success. Additionally, dont be afraid to think outside the box a bit. Look for scholarships that relate to your hobbies, passions, and even what you think you may want to major in. These scholarships will have a smaller school of applicants due to the specificity, and you will be able to make your case more easily since it is a topic you enjoy and are knowledgeable about. Dont stop after just a few, keep Google-searching scholarships regularly because you never know what new option may pop up each day. Just because one scholarships timeline ends doesnt mean another wont begin soon. 2. Procrastinate Just like you dont want to wait until the last minute to complete a school assignment, you also dont want to wait until the last minute to complete a scholarship application. The judges will be able to tell if you rushed through it, and chances are, you wont be able to get all the ideas you once had for the application down on paper in time. Procrastination is also relevant in terms of searching for scholarships and why you should always be looking. The last thing you want is to find a really great scholarship you think you deserve, but the deadline is in an hour. Trying to submit an application late will get you nowhere, either. Even if the committee accepts it, they are going to look it over with an extra-careful eye, even more so than before. 3.  Be careless Carelessness will immediately knock you out of the scholarship running. Judges read hundreds of applications, and the last thing they want is to read one with spelling and grammar mistakes all throughout it. Take the time to proofread your papers just as you would a school paper. Even more importantly, make sure you read the directions to the scholarship application. Reading an essay that does not answer the question being asked is definitely not something a judge wants to do. If you are applying for a lot of scholarships, keep yourself organized as to which asks for what. 4. Be lazy Do your own work, do it well, and be creative. Dont use the same essay for five different applications. Judges can tell when only a name has been changed in an essay, and they wont like it. If you really want the scholarship, then take the time to write why. Additionally, make sure it is you that is writing the essay. Dont send the application off to your parent to complete. Judges can tell that too. A 50-year-olds writing tone is different than a 20-year-olds, and only you can really write about yourself. 5. Pay to apply If you are asking for money, dont choose a scholarship that requires an application fee. There are plenty others out there that do not, and you should choose those first because then you will not lose any money in the process. You dont want to work backward in the process. 6.  Refusing to submit a recommendation A recommendation goes a lot farther than you may think. Having someone else write positive notes about you says a lot, even more than you can say about yourself. If an application leaves a space for an optional recommendation, put one in. Its the little extra something that shows you went through the entire application, that you care enough to go out of your way for the additional materials, that you have a good reputation it could be that little extra something to make you win. While no one wants to fill out another application after completing all of the college applications, scholarships can serve as a nice way to take the edge off of the daunting price tag, and they can allow you to have some extra money to participate in other activities campus has to offer. But if you are going to even bother applying, you mind as well do it the right way first. So, take yourself to a coffee shop, sit down, and dedicate a few hours to researching scholarships and organizing them by what they require and when they are due. Then, step away for a day, and come back to start the applications. Dont be one of the people listed above. Plenty of people will make those mistakes, and you can beat them all. Good luck!
