Organic Chemistry

Organic ChemistryA GC by organic chemistry is a metal ion analyzer. The three most common types of GC are ion source, gas ion, and catalytic. Each of these four types of GC is quite different from the other in some way or another.An ion source GC is actually an air ionizer. It can detect a specific analyte that is present in the body. This is why they are commonly used for tracking, therapeutic purposes, and legal reasons.An air ionizer is a piece of equipment that uses a carbon atom with an atom on it attached to make a negative electrical charge. A device like this will then throw a stream of ions onto a surface that is charged with an analyte. This is how it can perform the function of electrochemistry. Although the gas-gene, ion-chemical, and oxidizing (ion-catalytic) systems work in tandem, they do not come close to matching up in accuracy.A gas ion GC is usually combined with a mechanical system to analyze organic chemistry. In this type of GC, a chemical which is analytically relevant is added to the room air. The stream of ions is then thrown into the air ionizing the analyte.Usually, an analyte that is capable of inducing biotransformation is measured using the cathode. One commonly used analyte is Cytochrome P450 (CYP). CYP is a kind of family of metabolizing enzymes that metabolize a variety of natural compounds, including alcohols, ketones, amino acids, and sugars.In organic chemistry, the CYP family is responsible for the metabolism of organic compounds. Although CYP is found in all living things, the cell's catalytic CYP enzymes are only activated when needed. They are required to help initiate the metabolism of organic compounds, which means they are not always available.In organic chemistry, the process of metabolization involves the release of energy from the substance being metabolized, whether that is by ATP or NADH. These molecules are then used as a source of energy. So, if you want to convert an alcohol into acetaldehyde, it would require the use of ATP. However, acetaldehyde only exists in the presence of alcohols, ketones, and other ketogenic compounds.A catalytic GC is a very useful analyzer. This type of GC is used to determine the reaction rate of reactions. The products of a reaction are basically used as fuel for reactions. Therefore, by determining the rate of reaction, the quantity of reactants needed to make a reaction to occur, and the rate at which those reactants are used up, a catalyst can be determined.

3 STEAM Activities to Try in the New Year

3 STEAM Activities to Try in the New Year STEAM is a growing movement that gears students toward innovation, problem-solving, and high-level critical thinking. Incorporating the arts into academics teaches students valuable skills, while simultaneously aiming to deepen math and science concepts in insightful and interactive ways. There are a plethora of STEAM activities to try in 2019, specifically ones involving building structures, growing plants, and exploring nature. Looking to find new projects to enhance your students education? Keep reading to discover three STEAM activities to try in the new year. [RELATED: What is the STEAM Movement?] STEAM activity #1: build creative structures The most basic toyssuch as LEGOs or wooden building blocksare a wonderful foundation for STEAM. You can get creative with materials you already have at home, such as cardboard, pipe cleaners, popsicle sticks, and toothpicks. Challenge your student to see who can build the tallest tower or the longest bridge. You might also consider constructing other types of structures beyond traditional buildings, like boats and roller coasters. If your child would like a more advanced challenge, try building a rocket or a catapult. Encourage your student to consider how different materials provide advantages or disadvantages depending on their properties. STEAM activity #2: grow a garden Another excellent STEAM activity is to steward growth of some kind. This can be a houseplant or even a gardenif you have the space at home or at a community garden plot. Besides these more conventional projects, have your student work on their own container garden, like a miniature greenhouse in a soda bottle or glass jar that your child can decorate. Try growing a crop like sprouts, which work great on a small scale. These long-term activities will allow your student to observe changes over time and to watch how shifts in temperature, water, and air affect the ingredients. [RELATED: 3 Winter Art Crafts for Kids] STEAM activity #3: explore nature Teach your student to spend time watching how items grow in nature. Take a walk and observe whatever you can find at a park or in your backyard, recording it via a medium like drawinga tree, fallen leaves, or even snow. Encourage your child to ask and answer questions, such as the following: What happens to snow on the first day it falls, and each day after? How is the growth that you see outside during winter different from that in the fall or spring? What has persisted through the winter months in your specific area? When you happen upon interesting plants or trees that interest your student in some way, research them when you get home. Have your child incorporate any items that they can safely take home into their art projects as well. [RELATED: How Parents Can Help Students Setand AchieveAcademic Goals] While many STEAM projects can be done for free with items you find outside or at home, you can also check out kits made especially with STEAM in mind.

Mary Cassatt

Mary Cassatt Mary Cassatt: Give me Pastels; Give me Gouache! ChaptersYoung Mary: Getting a Feel for ArtThe Life of an Artist in ParisOn the Quest for AcceptanceMary Cassatt, ImpressionistMary to the EndWhen one thinks of great art, French painting and anything from the Italian Renaissance period comes readily to mind.If one is inclined toward van Gogh â€" impressionist painting as well as expressionism, works by the likes of Paul Klee or Edvard Munch easily spring forth.Does one dare throw The Boating Party in the ‘great art’ mix? What about Mother and Child or In The Box?These and other great artworks by the American painter in Paris are often overlooked in favour of other, more renown tableaux. Mostly, the name Cassatt draws... at best puzzled stares, at worse, blank looks.The sad part is that that is the treatment Marie Cassatt suffered for just about her entire artistic career.Today, we put an end to that by understanding who that American woman with the French-sounding name was. Why was she so set on painting? Why couldn’t she see h erself marrying, settling down and raising children, as was expected of her?We look at the tender scenes she painted that belied her struggle for acceptance as an artist of merit. We uncover just how much she was willing to put on the line in the name of art and, in the end, how she was undone by a certain magnificent art installation.Superprof now presents Mary Cassatt.

When she entered the world on May 1844, her father was a successful stockbroker and land speculator.The family had a rather elevated pedigree; Dad was a descendant of the original Dutch settlers in Manhattan. Mum too came from a privileged background; she was well-read, with a taste for refinement.It was her mother who introduced her to art.She believed that proper education involved exposure to the wider world. Thus, she took her brood to the capitals of Europe: Berlin, Paris, London and Rome. Little Mary drank it all in, even learning to speak German and French.She also had her first art lessons â€" drawing and music, while in Europe.Before Mary was of school age, the family moved east, ultimately settling in Philadelphia, where she attended school.Upon completion of her compulsory education, Mary and h er father endured a lot of friction.Mary wanted to study art and her father could see no point in it. Her mother may have interceded on her behalf; at age 15, she was enroled in the Pennsylvania Academy of the Fine Arts.Her mother and certainly her father must have had reservations about their teen-aged daughter being exposed to feminist ideas and other vagaries that may corrupt her; they especially feared predatory males.Their fears were for nought. Although the student body was overwhelmingly male, those students nevertheless believed that women and men could create art equally well and should enjoy the same freedom to do so.Being exposed to such liberalism at such a tender age shaped Mary’s worldview. For her entire life, she and all of her classmates remained advocates of equal rights.While the temperament suited Mary well, she grew ever more frustrated with two aspects of her art studies:1. About 20% of the student body was female but, unlike her, they were only learning how to paint as a social skill; they did not have any intention of pursuing a career in art.2. Because she was most serious about her art, she was subjected to patronising attitudes from both her classmates and instructors.That last was most injurious and, added to her frustration with the slow pace of the instruction and gender-based restrictions such as being forbidden to work with male models, Mary soon found she had no choice but to set off on her own.By contrast, Artemisia Gentileschi had no such credibility problems!The Life of an Artist in ParisAs there would be no certificate or degree for all of the academic art she created, Mary again tussled with her family, finally wrangling permission to establish herself in Europe, to learn how to paint from the masters.So, she set off, at the age of 22, with a rotation of chaperones keeping her company.However progressive Mary thought the Paris art scene would be, she must have been sorely disappointed to learn that females were barred fr om the School of Fine Arts. Or maybe she was angry!Undeterred, she petitioned for private lessons with the art teachers. Finally, Jean-Leon Jerome, a painter and sculptor in his own right, agreed to take her on.He might have been surprised at her dedication to learning; not only did she attend every session without fail but, when not in the studio, she was haunting the Louvre, copying the original paintings hanging there.She may have been dismayed at the number of female artists in that art museum, all busily sketching, as she was. She soon discovered that it was quite common for a female artist to sell their sketches to tourists because of the many roadblocks to their being an artist.One such block for  women artists in Paris must have been that they were denied entry to the cafés where all of the great (male) painters tarried. Nevertheless, Marie met and built ties with some of the greatest names in western art: Edouard Manet, Auguste Renoir and, most importantly, Edgar Degas. Wi th him, she enjoyed a lifelong artistic partnership.Do you know who Frida Kahlo’s mentor was?And then, war broke out. Her early impressionist tableaux showed social scenes such as theater and carnivals Source: WikipediaAlso learn about Georgia O’Keeffe, another great American painter... In her later years as an artist, Mary depicted mainly maternal scenes Source: Mary Cassatt.org via WikipediaMary to the EndMary had decided, early in her career as an artist, that she would never marry. Not only was marriage incompatible with the life of an artist but she felt she simply did not have the temperament for it.Indeed, Mary could be ill-tempered, self-centred and narcissistic. Perhaps those traits are a job requirement for artists.Still, she painted scenes of motherhood with such tenderness and, one might think, so much longing that some say she enjoyed motherhood through her depictions.Still, if she missed being a mother or even being married, she gave no outward signs of it; she continued to travel and paint well into old age.At 74, on a journey through Egypt and, upon seeing the ancient works on display in their museum of art, she became so overwhelmed by their beauty and magnitude that her creativity was stifled, at least for a time.Finally, at 80 years old, she gave up painting â€" but only because she could no longer see and it pained her greatly to hold a brush. She lived another 12 years, tortured by the fact that she could not see her beautiful world, much less paint it.Mary Cassatt is but one of many famous female painters who gave up everything for art, making our world more beautiful in the process.

The Complete Glossary of Singing Terms

The Complete Glossary of Singing Terms Jessica Dais If you’ve ever felt confused by unfamiliar singing terms, you’re not alone. As with every specialized field, vocal professionals tend to throw around a lot of jargon, or terminology that most people aren’t familiar with. If you’re interested in expanding your musical skills, learning these singing terms will help you better understand instructions from both voice teachers and conductors. Lets get started! 50 Singing Terms Their Meanings In this alphabetized list, youll find definitions for some of the most common musical terms, including choir terms. Youll also learn several new ways to describe a voice, such as breathy or dramatic. A Cappella: Literally meaning “of choir” in Italian, the term has been adopted to refer to singing without accompaniment. Alto: A lower female voice within the choral setting. Articulators: The parts of the body used to form words; usually refers to the lips, teeth, and tip of the tongue. Aspirate: A diction term referring to a sound that produces an audible puff of air, such as the letter P in English. Baritone: A male voice type between tenor and bass. Bass: The lowest male voice type. Breathy: A vocal sound that is not clear, while instead sounding airy and fuzzy. A breathy sound can be caused by many factors, including inadequate breath support. Chest voice: The lower vocal register in which most people talk; resonates in the chest. Contralto: The lowest female voice type. Coloratura: Fast-moving notes. Countertenor: A male voice type that sings primarily in head voice. Common in baroque music. Covering: A vocal technique wherein the singer rounds the lips slightly when singing high notes to achieve a specific sound. Dental: A diction technique referring to sounds that occur when the tongue is right behind the top front teeth. The Italian or Spanish D sound is a good example. Diaphragm: The large muscle of respiration that lies beneath the lungs, which flattens and lowers during inhalation. This is one of the most common singing terms used in lessons or classes when discussing proper breathing technique. Diction: The way in which components of words, including consonants and vowels, are formed and pronounced. For classical singers, this generally includes the study of foreign language diction. Diphthong: A diction term referring to the phenomenon of one vowel gradually changing into another vowel, creating two vowels within a syllable. This happens a lot in English (e.g. in the word “ray”) but happens less in other languages. Dramatic: In voice classification, this refers to a large, robust voice (e.g. “dramatic soprano”). Extended technique: Any vocal technique outside of what is normally and classically taught. This includes whistle tone, inhaled phonation, throat singing, and many other techniques. Fach: Voice type or vocal classification. Also means “subject” in German. Flat: When a pitch is slightly lower than desired. Falsetto: A thin head voice sound produced by men. Glottal fry: The croaky, low register that some people speak in due to lack of breath support. It often occurs at the ends of sentences. Glottal stop: The sound created when a person presses their vocal folds together before beginning a vocal sound. Manifested at the beginning of many words that start with vowels in English, including “umbrella.” Head voice: The upper vocal register in which women and countertenors primarily sing in classical music. Intercostals: The muscles in between the rib cage that lift the ribs out and up during breathing. Larynx: The structure in the throat that contains the vocal folds. Low breath: The use of the diaphragm and intercostals to breathe without moving the shoulders, neck, or upper chest. This type of breathing is desirable in singing. Lyric: A voice classification term between dramatic (heavy) and coloratura (fast/light). Can occur in various voice types (e.g. lyric baritone, lyric soprano). Messa di voce: A dynamic technique involving starting a note with a crescendo (quiet to loud) followed by a decrescendo (loud to quiet). Mezzo soprano: The operatic female voice classification between soprano and contralto. Onset: The beginning of the vocal sound. Passaggio: An Italian term translating to “passage,” this refers to transitional areas in the voice where the singer must take extra care to sing well. These occur in different spots according to the individual and voice type. Phonation: The creation of a vocal sound. Registers: Parts of the voice differentiated by vocal quality and sometimes range, such as chest voice, head voice, and falsetto. (Each of these singing terms were defined previously). Resonance: This is another sound quality term, such as tone. It refers specifically to how round or warm the sound is, which has more to do with overtones. It can also refer to the way a sound interacts with a room, such as a cathedral. Sharp: When a pitch is slightly higher than desired. Soft palate: The soft muscular structure at the back of the mouth that, when lifted, separates the nasal cavity from the rest of the respiratory system and therefore stops singers from singing out of their noses. Soprano: The highest female voice classification. Squillo: Another sound quality term, this refers to the edgy, clear tone some singers have, particularly in their upper registers. Straight tone: A vocal sound without vibrato. Tenor: A high male voice classification. Tone: The quality of a voice. Usually described with adjectives such as raspy and clear. Timbre: Similar to tone, this refers to the quality of a vocal sound. Trill: A technique in which a singer quickly moves between two adjacent notes. Unvoiced: A diction term referring to consonants that don’t involve vocal sound, such as S and T. Vibrato: The natural oscillation between pitches (even when singing a held note) present in many singing voices. Vocal cords/vocal folds: These mucus membrane cords, nestled in the larynx, vibrate together when air passes between them, producing vocal sounds. Voiced: The opposite of “unvoiced,” this is a diction term referring to consonants that require vocal sound, such as B and Z. Whistle tone: The highest vocal register, located above head voice and made famous by Mariah Carey. Wobble: A phenomenon that occurs when the distance between the two pitches present in vibrato becomes too wide, causing an unstable sound.
