What Is Shielding Chemistry?

What Is Shielding Chemistry?For many generations, shielding chemistry has been a popular subject. This area of science focuses on the quality of shielding techniques in that it can be used to protect both basic materials and complex devices, and also for their protection from other kinds of pollutants. A shielding technique is usually a combination of elements with different properties that are used to form a material, which is then put into an enclosure.Generally, the barrier is formed from a semi-solid material, and this is referred to as the general shield. There are two types of shielding techniques that are commonly used for devices, the layered shield and the discrete shield. Both techniques have different approaches in that they use different elements, structures, textures, and materials.Layers: A layer of metal or another material is inserted in between two sides of the device. This layer is to provide a certain level of protection to the device. For instance, it may be a foi l sandwich that is to be placed between two layers of copper and nickel. This is one of the most common techniques for shielding in today's modern times.Sub-sub-sub-substances: Many shields have very small sub-sub-substances that are commonly known as 'permeations' of this shielding technique. Permeation shields are widely used as shielding methods for hydrogen, acids, and gases. They are highly efficient in providing high efficiency at a low cost.Discrete Shield: A discrete shield can be divided into three main components, these components are the encapsulating shield, and the emission shield. The encapsulating shield is to prevent the device from having too much heat. The emission shield helps in the reduction of the noise as the device is placed in a static environment.The field of shielding chemistry is highly complex, with many different shielding materials that can protect a wide range of devices from different kind of threats. Depending on the specific use of the device, a di fferent shielding technique can be used to protect the device from certain threats.Therefore, shielding chemistry is indeed a special technique that has its own merits, challenges, and benefits. We strongly suggest that you take the time to explore this exciting field before proceeding any further.

Ear Training Exercises for Singers - Part 1

Ear Training Exercises for Singers - Part 1 Suzy S. Having trouble staying on pitch? Developing your ear even if youre convinced you werent naturally born with the skill can do wonders for your singing. Read on as Raleigh, NC teacher Cameron F.   explains As a vocalist, nothing is more important than a well-trained ear. This is all we have to depend on to tune ourselves! We have no frets or keys, no strings and no tuning pegs, only our vocal cords to create the sound and our ear to focus the pitch. We have to make sure the tools we do have are well crafted and reliable. This is where ear training comes in. We have to listen to what is happening in the music around us and change ourselves to fit it. Even those lucky enough to have perfect pitch must abide by this rule. If the ensemble is playing a little sharp or flat, the singer has to move with them. So you can see how important ear training is! Highly trained singers are able to sing well and on pitch with the most challenging ensembles. So, let’s take a look at a few things you can do to train your ear. There are two main techniques that I will be going over, one of which is very basic, the other much more advanced. Let’s start with the basics. As a beginner, the most important skill to develop is the ability to match pitch. This is the cornerstone to singing in tune, and is the ability to hear a note and recreate it with your voice. Many people are able to do it naturally, but if you can’t, don’t worry! You are not out of luck. A very basic way to begin matching pitch is to start by creating it yourself. Sing any note you want, and ask someone, preferable someone more musically experienced than you are, to find it on a piano, or any other instrument. Ideally, another singer would be best. When choosing your pitch, make sure you sing in a range that is comfortable and relaxed for you. Once they have found your pitch, stop singing. Listen to the note they are playing, and remember the note you had chosen (they should be the same). Now try to recreate the pitch while your assistant continues to hold your original note. Do this with many different pitches, and eventually you will be able to switch roles. Your assistant will chose the pitch, and you will be able to match it! You can also follow along with a video like this one on YouTube for practice: It is important to mention something about the physics of sound here, as this bit of knowledge will help beginners hear when they are close, but not quite on the right pitch. In scientific terms, a musical note is referred to as a “frequency. When two frequencies are very, very close but not identical you may notice volume swells (or beats) in the pitch. The further away from each other the two pitches are, the faster the swells. This is how most musicians tune their instruments by ear. For singers, this can be helpful in many ways. Many who are just learning to match pitch complain that they have a hard time telling if they are too low (flat) or too high (sharp). If you can get close, than listening to the beats will help you figure that out. Change the pitch in one direction and see if the beats speed up or slow down. If they speed up, go back in the opposite direction. If they slow down, then you’ve got it. Remember what it sounds like when you have to move up, and vice versa. Eventually, you will figure out which is which just by listening. From there, you can move on to slightly more advanced exercises. Have your assistant play a few different notes on a given instrument and try to sing them back to him/her, as a warm up. After doing this for a while, have him/her play two notes at the same time. Listen very carefully, and try to separate them. Your assistant should ask you to match one of the two notes, and then the other. Once you are comfortable with that, have your assistant play three notes at a time, and repeat the process. This will be more difficult, but the benefits are huge. Being able to separate chords is a great skill for any singer to have, as it will allow you to feel more comfortable and knowledgeable within any musical setting, as well as help you improvise, should you need to. That is it for the beginner’s lessons. Next week I will cover an exercise that is extremely useful for more advanced musicians: transcription.

List of Electrolytes

List of Electrolytes List of Electrolytes Definition of an Electrolytes: An electrolyte is a substance that ionizes into positive and negative ions when dissolved in an aqueous solution. These free ions in a solution consists of the property of conducting electricity in the aqueous state. The strength of the electrolyte depends on its ability to disassociate and conduct electricity. There are basically three types of electrolytes: Strong Electrolyte: A strong electrolyte when dissolved in water forms a solution that is a very good conductor of electricity. This implies that a strong electrolyte is a solute that completely or near to complete dissociates into all its ions in the solution. At the same temperature a solution of strong electrolytes has greater vapor pressure than pure water. Strong electrolytes include strong acids, strong bases and ionic salts. Mentioned below in the table are few examples for strong electrolytes: Strong Electrolyte Name List of Acids HCl Hydrochloric acid HBr Hydro-bromic acid HI Hydro Iodic acid HIO4 Per Iodic Acid H2SO3 Sulphurous acid H2SO4 Sulphuric acid HNO3 Nitric acid HBrO3 Bromic Acid HBrO4 Perbromic Acid HClO3 Chloric acid HClO4 Per-chloric acid List of Bases LiOH Lithium Hydroxide NaOH Sodium Hydroxide KOH Potassium Hydroxide Ba(OH)2 Barium Hydroxide Ca(OH)2 Calcium Hydroxide Sr(OH)2 Strontium Hydroxide RbOH Rubidium Hydroxide CsOH Caesium Hydroxide Mg(OH)2 Magnesium Hydroxide NaH2 Sodium Amide NaH Sodium Hydride List of salts NaNO3 Sodium Nitrate NaCl Sodium Chloride LiCl Lithium Chloride KCl Potassium Chloride CuSO4 Copper Sulfate KNO3 Potassium Nitrate CaCl2 Calcium Chloride CH3COONa Sodium Acetate NaHCO3 Sodium Bi-carbonate AgNO3 Silver Nitrate The dissociation of the strong electrolyte occurs in one direction, which implies it is not reversible. The below equation is mentioned in an aqueous state because a strong electrolyte conducts electricity only in an aqueous state. Cations and Anions: The ions can be classified into two types the cations and the anions. The cations are positive changed ions which are formed by the loss of electrons. The anions are negatively changed ions which are formed by gain of electrons. Here is an example showing the disassociation of NaCl in water. This gives rise to two ions the sodium cation and the chloride anion in an aqueous solution. The disassociation is not reversible as NaCl is a strong electrolyte. Weak Electrolyte: The electrolytes in which the solute does not completely dissociate in the solution is called a weak electrolyte. This implies in such solutions there are disassociated ions as well as molecules of the electrolytes. Therefore the weak electrolytes ionize less in aqueous solutions and conduct very less amount of electricity. Mentioned below in the table is a list of few weak electrolytes: Weak electrolytes Name Acids CH3COOH Acetic Acid H2CO3 Carbonic Acid H2CrO4 Chromic Acid HF Hydrofluoric Acid C6H5COOH Benzoic Acid HNO2 Nitrous Acid H3PO4 Phosphoric acid H(C3H5O3) Lactic Acid (COOH)2 Oxalic Acid Bases NH3 Ammonia NH4OH Ammonium Hydroxide HCN Hydrogen Cyanide C5H5N Pyridine (CH3)2NH Dimethylamine (CH3)3N Trimethylamine C2H5NH2 Ethylamine C2H3N2 Glycine The disassociation of a weak electrolyte is usually an equilibrium equation. This is because the weak electrolytes partially disassociate into positive and negative ions. Mentioned below are two examples for the disassociation of a weak electrolyte: The Hydrogen cyanide when dissolved in an aqueous solution disassociates partially being a weak electrolyte. The HCN disassociates into a hydrogen cation and a cyanide anion in an aqueous state. The Ammonium hydroxide disassociates into an ammonium cation and a hydroxide anion in an aqueous state. Non-Electrolyte: A substance which when dissolved in water lacks ions due to which there is no disassociation is called Non-electrolyte. A non-electrolyte has no ionization therefore it cannot conduct electricity. Most non-electrolytes are polar or non-polar molecules as they dissolve in water as molecules but do not dissociate as ions. Non Electrolyte Name O2 Oxygen SO2 Sulphur dioxide CO2 Carbon dioxide CS2 Carbon disulphide CCl4 Carbon tetrachloride H2O Water CH3OH Methanol C2H5OH Ethanol C12H22O11 Sucrose C6H12O6 Glucose NH2CONH2 Urea CH2Cl2 Dichloromethane CH3H8O3 Glycerol Electrolysis: Electrolysis is the process of passing current through a solution of an electrolyte. In this process of electrolysis the negative and positive ions move towards their respective electrodes. The electrode attracts the ions of the opposite charge towards itself. Electrolytic cell: The Electrolytic cell, is where the process of electrolysis is conducted. The electrolytic cell consists of a beaker which is filled with the electrolytic solution. This cell is then connected to two conducting plates called the anode and the cathode. The anode is a positive electrode that extracts electrons from the negatively charged ions which are the anions. The cathode is a negative electrode that provide electrons to a positively charged ions called the cations. These two electrodes are connected to the D.C power supply terminals. The electric current enters through the positive electrode which is the anode passes through the electrolytic solution and leaves through the cathode. The process of oxidation which is the loss of electrons takes place at the anode. The process of reduction which is the gain of electrons takes place at the cathode. What exactly do the electrolytes do? A body cannot function without the electrolytes due to the important role they play in the cells. They regulate the nerve and the muscle function in the body. They help in maintaining stability in the cells and generate energy when required. They control the body hydration, the pH levels in the blood and the blood pressure. They responsible for rebuilding the damages tissues. The electric tissues in the body are muscles and neurons. Electrolytes activate these electric tissues by: o Extracellular fluid (The fluid outside the cells.) o Interstitial fluid (The fluid inside the cells.) o Intra cellular fluid. (The fluid between the cells.) The calcium (ca2+), Sodium (Na+) and potassium (K+) are required for muscle contractions. The kidneys and other hormones present in the body ensure the electrolyte levels are balanced in the body. Exercise helps in losing the ions such as sodium and potassium and retain the balance. Eating a balance food especially the fresh fruits and vegetables regains the lost sodium and potassium levels in the body.

From What Age Should I Get Academic Support For My Child

From What Age Should I Get Academic Support For My Child What Is The Ideal Age To Begin Private Tutoring For My Child? ChaptersA Spotlight On The Stages Of Child DevelopmentWhat Can Academic Support Services Help With?What Are The Rules For Your Child’s Development“The Early Bird Catches The Worm.” (British Idiom)The keys to opening the doors of opportunity and success for your child are often found in academic support, education and experience. Finding the balance for your child to enjoy their childhood and begin their education can be a difficult decision to make as parents. But ask yourselfWhat could my child be capable of if given the tools?As parents, we can see formal education as something that should be reserved to start when the child is ready to go to kindergarten or nursery. But this idea couldn’t be further from reality that education is not just exclusive to the school institution, but it is integrated into all forms of life. From the moment children are born they are engaged in learning, they are learning from their parents, their environment, their experiences and their own rea ctions to everything that is going on around them.Thinking of education as separate from life itself is not useful for either the parents or the child. To be successful, we should treat education as a natural part of life, and be aware that starting early can empower your child to integrate with their formal learning process later on seamlessly. This could be a non traditional idea, but I have never heard of a receiving a head start in life as a drawback. Starting early is often seen as the prerequisite to success, self empowerment and academic excellence and it should be a priority for your child.Thankfully our cognitive skills can be improved, when weaknesses impact learning.

He also looked at how intelligence is constructed, stored and applied.Cognitive skills are active mental activities which are required to help humans to remember, solve problems, focus, think and learn. These skills include memory, reasoning, sensory processing, logic and processing speed.   We use them in every part of our lives because cognitive skills are critical in helping us to accomplish tasks, store knowledge effectively and apply what we know successfully for our personal advancement.Each child has cognitive strengths and weakness which are unique to them. Some children may excel at logic or reasoning for example and may actively present above average in skills in those areas. Likewise, some children may fall behind in other cognitive areas for example memory or processing speed. Cognitive skills are some of the critical building blocks that decide if we will succeed or struggle.  Thankfully our cognitive skills can be improved, when weaknesses impact learning. One on one tutoring can use specialized learning strategies. To ensure that gaps are strengthened collaboratively, with a focus on the national curriculum, key learning stages, regular practice and attention to the best student outcome. Which will eventually navigate the child on the road to academic success and lifelong excellence.Piaget was an advocate for child education and supplemental higher education like one on one home tutoring or small group mentoring. He advised that children have 4 developmental stages and at each stage different core cognitive skills are developed.Stage one â€" A child from birth to 2 years old learns about the world through their sen ses and by engaging closely with objects.Stage Two â€" A child of 2 years old to 7 years old begins to develop their imagination, memory and comprehension of concepts such as the past and the future.Stage Three â€" A child of 7 to 11 years old starts to gain awareness about the feelings of others and apply to this the understanding about the individuality of beliefs, thoughts and emotions of people around them.Stage 4 â€" Children who are 11 years old and older are able to use planning as a tool to succeed in the future, they can additionally solve problems accurately and appreciate the world around them.As you can see from Piaget's strategic processing model a child from birth is already learning and developing. The extended version of this developmental model highlights that from as early as the age of 2 years old children are already improving their memory and focus. Memory helps them to retain information and consult that information at will. Attention and engagement will allow them to complete tasks successfully without being distracted by everything around them.From the ages of 2-7 Children are developing sensory processing skills which are useful for things like imagination, reading and writing instruction, Logic and reasoning also expands allowing the child to solve problems and make connections with related ideas.It may feel odd to look at your tiny baby and think of them already as students, but even within their first year, they are students of life. If you agree to assist in your child’s supplemental instruction, in the form of a private one to one tutor or online tutoring. You will help with their faster development, increased academic performance, individualized exploration of topics, academic enrichment and overall higher student achievement.There are many tutoring centres which are explicitly working with minors as young as a few months old. Learning styles for early years students differ significantly between tutors and tuition centres. But general education requirements are advising that all test-taking is of course actively discouraged, and experiential learning through play is highly encouraged.As a parent, you must be prepared to challenge the ‘norm’ to give your child the tools that they need to reach their highest potential. Early academic tutoring is an excellent way to keep your child not only on track but excelling in all areas of their young lives.Discover all of the benefits academic support provides to even the youngest scholars!Starting early is often seen as the prerequisite to success. Photo Source: UnsplashWhat Can Academic Support Services Help With?If you recruit a private tutor or academic support tutor for your child, it is essential to know what options are available. Although tutors do specialize in different areas, all tutors are committed to student success and have the following prioritiesTo bridge the gap for students who have fallen behind and no longer meet expectations for their age and ability.To support vulnerable children who may struggle due to their circumstances such as children who speak English as a second language or for students with a known learning disability.To relieve anxiety, stress and low self-esteem about Raising confidence, interest, motivation and engagement for the child’s education. Promoting student health, wellness and achievement for the child.To support each child to excel and do their best in the academic environment, guiding them from the academic struggle to academic success.To prepare the child for learning and doing well in their education. Giving them access to essential resources such as study skills and learning strategies.To work with the child at their own pace of development and using required resources to facilitate positive learning experiences.What types of learning support is available to your child?From the moment children are born they are engaged in learning. Photo Source: UnsplashWhat Are The Rules For Your Child’s DevelopmentThe government make it compulsory for children between the ages of 5 years old and 16 years old to have access to a suitable full-time education that meets their needs. However children from the ages of 4 to 5 years old are already being assessed, and some children are being reviewed from the ages of 2 and 3 years old if they are in nursery.Although early years learners are not given exams and are tested by observation only, they are still expected to be able to achieve outcomes for their age group.The main areas of assessment, which your child should be able to demonstrate by the age of 5 years old arePhysical developmentVerbal communicationSocial and emotional developmentCreativity and self-expressionBasic literacy and mathsAs you can see the world will not wait to assess your child and give them an assignment for a ‘good student’ based on these performance prerequisites. The implications of them doing poorly and having their self esteem affected at such an early ag e is unthinkable. You can take advantage of early years private tutoring which can support students in and out of the classroom, babies, children, teenagers and adults alike. But it can be especially useful for struggling children, especially if you notice an issue with their learning development.Children may have challenges with retention of information, poor study habits, a learning delay, a learning disability, English as Second Language (ESOL), a vulnerable international student, a child facing poverty in need of financial aid or a gifted child with intellectual development beyond the expectations of their age. Engaging a tutoring instructor to encourage your child as early as possible is an excellent idea to give them the best start in life available.Learn also why it is vital to get your young learner the help s/he needs as soon as possible!Hands-on support for students who have different developmental needs is one of the primary ways to support a child towards realising their full potential. Tutoring can help a child achieve academically and personally as it is focused on providing a complete environment for your child to excel and do their best.Academic support tutorings services have tutors from all walks of life who have experience with different kinds of students, with varying specialisms of the core subjects and different ages of children as students. A child’s success is never dictated by their age but by their interest and willingness to take advantage of working with the tutor, to learn the necessary academic skills and to absorb the strategies taught which will lead them to success and personal achievement.In fact, early education is vital for the child’s healthy growth and development. The younger a child is, the easier it will be for them to adapt to positive study habits later on. A young child, who has experienced success, is much more likely to grow up to be a confident learner and engage in their academic achievement. Encouraging and enrolling your child with a tutoring service is an investment in their intellectual development and prosperous future.If your child has the capacity it is never too early, take the initiative, empower your child today by following these suggestions for finding your perfect tutor for any stage of learning.

Using the English Future Continuous (video and exercise)

Using the English Future Continuous (video and exercise) This is the second video about advanced future forms. Do you know when to use the future continuous in English? Are you using it correctly?We use the future continuous in English for three specific reasons:1. To indicate that we will be in the middle of doing something in a specified future time.2. An activity that starts now and continues to a specific future time.3. When a longer action in the future is interrupted by a shorter future action.In the video below, Teauna will demonstrate these uses of the future continuous with example sentences and a timeline. English Exercise: create future continuous sentences from the incomplete sentences below.Example: What are you doing tomorrow morning? At 10 am tomorrow I (drive) to the dentist. - At 10 am tomorrow I will be driving to the dentist.1.Can you go shopping on Saturday?  No, this Saturday I (work).2.Is Alice available for class?    No, she (exercise) at the gym until 3 pm.3.  Im going to arrive at midnight.  I (sleep) when you come home.4.
