HOA Chemistry - What Is The Best Thing To Do If Your Home Has High Exposure Levels Of Chemicals?

HOA Chemistry - What Is The Best Thing To Do If Your Home Has High Exposure Levels Of Chemicals?HOA Chemistry is the fact that many in the community of parks and yards is very different from that of the rest of the city. The chemicals found within the natural areas can cause terrible and potentially life-threatening skin reactions and more than one young child has suffered from anaphylactic shock.If your HOA does not allow chemical exposure, do you really know what the chemical problem is in the city? You would be well advised to consult with a HOA specialist to help determine the substance that is causing the problem and perhaps devise a plan of action to restore and maintain a healthy environment.Chemistry is the study of how the molecules interact and how chemical reactions affect living systems. For example, our skin contains millions of sweat glands that secrete moisture to keep us healthy. Our bodies contain chemicals that are essential for survival, and often the important che mical is called the skin's own steroid hormone- Human Growth Hormone (HGH).Where do these chemicals go when they are taken in different places by different people? The main ingredient is known as a carcinogen. That means it is a chemical that causes cancer.Chemicals that increase the production of HGH are often carcinogens. But where do they go?They will go into the air, and many people believe that the chemicals used to create cosmetics cause the children's hair to turn gray at an early age. The exact cause of the phenomenon is unknown, but some medical experts believe that it could be connected to the hormone, the growth hormone. HGH can also affect the DNA, which can cause tumors.Chemicals, in our own bodies, are dangerous if we eat them. I know my grandfather used to tell me about his interest in alcohol, because he consumed some pure, untainted alcohol everyday.There are all kinds of chemical exposure problems, but one of the most serious is HOA Chemistry. Our families, our chi ldren, and our homes need a HOA specialist that can help us determine if our chemical exposure is causing problems. We should not allow these chemicals into our environment and the sooner the better.

Taking the SAT Chemistry Subject Test Dates

Taking the SAT Chemistry Subject Test DatesIs it time to take the SAT Chemistry subject test? The answer to this question can depend on how much homework you do. Take a look at this basic study tip:Just like all the other sections, the SAT Chemistry test consists of multiple choice questions. This means that you have plenty of time to work through the content. This is a good time to focus on whatever areas of chemistry you need to focus on the most.While the science section of the SAT does have some similarities with the physics section, there are some differences. In physics, you have to refer to the directions and check the materials. When taking the SAT, you will not have to look at any instructions or the materials. In the end, this can make it easier for you to study.While there are different possible topics in the multiple choice section, the content can be somewhat similar. The entire SAT test will typically consist of two parts. The first part consists of the verbal portion a nd the second part consists of the math portion.While you will probably want to focus more on the math section in the SAT, you can also choose to study in both sections if you want to. The SAT science section will also have some text-based passages and activities. While they may not be as extensive as in the physics sections, you should still be able to take some time to study these parts if you want to.You should take the SAT test on the same day as your previous week's schedule. Some schools allow you to take the test on the following day, but you must notify them and allow enough time to get prepared. This is especially important if you take the SAT before the deadline for the fall semester. Many schools have varying rules about rescheduling tests after this point, so make sure to check with the school you are considering to see if they allow this type of test date.If you have a lot of homework to do, you may need to adjust your plans slightly. Be sure to use a study guide to get through your homework and study the parts thoroughly. Your preparation may pay off when the test date comes around.

Finding Percent Online Tutoring - Maths Tutors

Finding Percent Online Tutoring - Maths Tutors Percent means out of hundred. For example if we say Twenty one percent that meanstwenty one is divided by one hundred. We can say that the percentage is a fraction in which the denominator is one hundred. Any value which is too calculated is divided by one hundred to find the percentage. The fractions, decimal and the percentage are associated with each other. All these are interchangeable. The fraction can be changed into decimal and the decimal can be changed into the percentage. 21% = 21/100, 85% = 85/100, 63% = 63/100, 17% = 17/100 Multiplying percentage is associated to find the percentage. When any fraction or decimal is multiplied by one hundred we get the percentage. i.e (7/10)X 100 = 70%, (17/10) X 100 = 170%, (1/5) X 100 = 20% The decimal number can also be converted into percentage by multiplying it by one hundred and then removing the sign of the percentage. i.e 0.13 X 100 = 13%, 0.56 X 100 = 56%, 0.81X 100 = 81% When the cost of any item is doubled then two is multiplied by one hundred to get percentage and it is said the cost has been increased by two hundred percentages. When the cost of any item is reduced to half then half is multiplied by one hundred and it is said the cost has been decreased by fifty percent. i.e C.P = 46 S.P = 92 Profit in percentage = (92 46) X 100 /46 = 100%

But even taken together, they do not begin to encompass the magnitude of this ancient society.To truly understand life in Mesopotamia, the civilisation’s social structures, innovations and cultural advances, we have to travel back to a time wher e few written records remain.Piecing artefacts together, your Superprof now weaves a fabric of life in ancient Mesopotamia.

Invasions and takeovers, led by powerful men or families were generally how leadership was won.A prime example of such: the Sumerians, the oldest Mesopotamian civilisation (and one of the first in the world, along with Ancient Egyptians), were overtaken by the Akkadians.They were permitted to keep their culture and way of life; in fact, they swapped cultural elements, especially language, to the point that both societies were, at one time, bilingual.Eventually, the Sumerian language became completely subsumed. By 2,000BC, everyone throughout the empire spoke only Akkadian.Are you curious to know how closely the Mesopotamian civilisation resembles Ancient Egypt’s?Mesopotamia in Economic TermsIn the foothills of the Zagros mountains, it was relatively easy to farm but further south, agriculture was only possible with irrigation of dry lands and frequent drainage of wetter areas.After gaining control of water, harvests became bountiful â€" so much so that Akkadians could afford to engage in a bit of trade with their neighbours.As they did not employ slaves, they had to devise tools to make farming easier; the use of wooden plough blades permitted them to plant onions, turnips and barley.This area that millennia later was dubbed the Fertile Crescent is known as the cradle of civilisation.The ability to grow food allowed the people to settle, establish cities and form governments, and spurred them to intellectual discovery.Religion was exceedingly important to them for many reasons, one of them being that their temples functioned as banks.The earliest large-scale credit system was developed b y the Sumerians but it was the Babylonians who developed the first commercial banking system.Was there a rivalry between the two?Not necessarily. After the Akkadian Empire fell, the region split into two nations: Assyria occupied the north while the Babylonian Empire encompassed the south. Both countries spoke the same language and actively traded with one another.So this was a peaceful time in human history?Between power grabs and fighting for territory, one could hardly contend that these early civilisations were content to coexist.There would often be fighting between cities; those battles would sometimes be arbitrated by an official of a nearby neutral town. Thus, strategic alliances formed. Later, as the region was governed by a succession of emperors, they mostly fought against foreign powers.A prime example of such is Sargon the Great, humanity’s first emperor, who often led campaigns into neighbouring lands to appease his constant hunger for territory.In Mesopotamia, warri ng was a fact of life.What was life like in Aboriginal Australia? Madrasas such as this were built to further Islamic instruction Image by Tuna Ölger from PixabayReligion in MesopotamiaThe earliest colonies praised natural forces â€" wind, rain and sun, because they helped to sustain life. It was only later that those forces became personified and a religious hierarchy was established.Early on, the deities demonstrated a balance of power between males and females.For instance, An was the name given to the supreme god, their personification of the heavens. The goddess Ki represented the earth.The Sumerian word for ‘universe’ is an-ki, reflecting their two highest-ranked deities.Their cast of gods soon grew to represent every aspect of Sumerian life, from the god of water to the moon goddess.One their pantheon of gods was established to oversee daily life, Mesopotamians turned their minds to greater philosophical questions.‘Who am I?’ and ‘What is my purpose?’ - the answers were construed as having divine influence.As society evolved, so too did the people’s relationship with their gods; it became more personal and, as more believers worshipped in their own way, Mesopotamian religion became more fractured.That had the effect of weakening the overall bond to their pantheon of deities.When Cyrus the Great claimed Mesopotamian lands as a part of his Achaemenid Empire, the people more or less abandoned their religious beliefs in favour of the religion their conqueror brought: Syriac Christianity.Do you know the deities of the Incan Civilization?Omens played an important part in mythology; it was thought that the will of the gods could be divined if only one could interpret the clues they occasionally gave.As such, a treatise was compiled regarding signs from the gods: what it means should a being be born deformed, for example, or what destiny awaits a people whose city is perched on a hill.Immortality was a common theme in Mesopotamian mythology: Etana, a king with no heirs, liberated an eagle and flew on his back to the heavens. This was meant to serve as a cautionary tale, warning against dynasties.Adapa, who had vexed the gods and was summoned to them, was careful to not consume anything the gods offered him, thus staving off immortality.From these two examples, it would seem immortality was undesirable. On the other hand...Atrahasis had been warned by the gods that a great flood was imminent. He followed their advice and built a boat, in which he was able to withstand the water’s great power.Ishtar was the goddess of fertility and war. Her descent into the underworld and subsequent reemergence justified the seasonal change from winter to summer.Mesopotamian mythology is full of stories that have been ‘borrowed’ and incorporated into other societies’ belief systems. In fact, they resonate still today, having undergone revision to suit new religious beliefs.What beliefs did the Ancient Greeks hold as truth? As depicted in this Sumerian tablet, warring became a way of life Image by Mariusz Matuszewski from PixabayMesopotamian CultureEarly in forming the Mesopotamian civilization, males and females had equal social power, a facet of the social fabric that changed dramatically over time.Women held positions as high priestesses in Sumer. They could own property, benefit from education and engage in a trade.Later, as warring became a way of life, women lost much of their social power: they were denied the right to education or to a trade. Soon, the societal role of females was reduced to caring for the home and children.Subsequently, Mesopotamia’s patriarchal social structure influenced every aspect of life.What kind of life did they have? What kind of life did the Mayans have?A Life of Leisure?Assyrian kings especially enjoyed hunting and the rich played an early version of polo â€" men rode on other men’s shoulders, not horses. Boxing was also a popular sport; scenes of boxers and wres tlers frequently adorned artwork.Board games were quite popular then. In fact, what we know as backgammon originated in Mesopotamia. Oddly enough, Islam expressly forbids the game even though it was invented by their ancestors!For the particularly energetic, there was a game similar to rugby, played with a wooden ball.Besides these pastimes, singing and music were important cultural signatures.People would sing at home or in the marketplace; oftentimes, songs were composed specifically to entertain royalty.  There were also plenty of drinking songs sung; after all, the Mesopotamians regularly brewed beer and made wine.Frivolity aside, songs had a far more important role to play in Mesopotamian culture.There were renderings of specific events such as battles or coronations, and they were handed down through the generations, becoming, in effect, oral histories.Musical instruments such as the lute, drums and other percussion instruments must have made for lively entertainment, especial ly as the Mesopotamians had developed an early form of music notation.Besides entertaining royalty, these early musicians were called on to play at religious ceremonies, funerals and festivals.Mesopotamian FestivalsPredictably, many of this people’s rites revolved around natural phenomenon:Lunar cycles: waxing moons were thought to encourage agricultural abundance; waning moons were times of conservation, reflection on philosophical matters and a time to revere ancestors.Seasons: sowing and reaping; celebrating a bountiful harvest or, conversely if pickings had been sparse, to implore the gods to intervene ahead of the next growing seasonThe first full moon after the Spring Equinox: called the Akitu or ‘head of the year’ in AkkadianEquinoxes: the days of equal amounts of light and dark must be observed!Solstices: the longest days and nights deserved special considerationNaturally, the reigning monarch and local heroes would be regularly celebrated, with odes and epics composed in their honour; the aforementioned Epic of Gilgamesh is a fine example of such.The fact that these tales were written and still exist today suggest that they originated from a very intelligent, organised society.Discovering proof of those people’s ability to observe natural phenomena such as solstices and equinoxes leads archaeologists to conclude that those living in Mesopotamia were very clever indeed.Did their celestial observations bear any resemblance to those of the Aztec civilization? Cuneiform is one of the world's oldest writing systems Image by Mariusz Matuszewski from PixabayTechnological AdvancesWe’ve already hinted at how technologically advanced the Mesopotamians were: irrigating dry lands and draining swamps, building ploughs and increasingly sophisticated weaponry to fight their wars...Right now, what is furiously debated in academic halls is whether the screw pump was actually invented by Archimedes, as has been long-thought.Many now believe such a device was used to water the Hanging Gardens of Babylon, which suggests the pump was invented some 350 years before he travelled to Egypt, making the device a Babylonian creation.Besides, a clay tablet with a description of how to cast a water screw in bronze, written in cuneiform by an Assyrian king, certainly lends credence to the new school of thought!Sumerian cuneiform is one of the earliest systems of writing, consisting of wedge-shaped marks in clay... another of Mesopotamia’s accomplishments.As the Mesopotamian civilisation endured for so long â€" by some accounts, more than seven millennia, they were instrumental in shaping the Bronze Ages, the Iron Age and Antiquity, meaning they were crucial to many of the innovations of that time.And, in case you were wondering, they invented the wheel!All of their innovation means that they left a substantial legacy.The Legacy of MesopotamiaPerhaps without knowing it, you use Mesopotamian math every day.Their numerical system, based on a value of 60, gave us the seconds, minutes and hours of our days. Ditto the number of degrees in a circle. We also got our 7-day week from them.While both Sumerian and Semitic languages were spoken in early Mesopotamia, cuneiform was invented for the Sumerian language only. This gave the world one of the earliest, complete writing systems.Thanks to this writing, today we understand and enjoy the culture and legends of a people long buried.Babylonian astronomers were adept at math, a faculty that permitted them to map the stars with stunning accuracy. Their ability to ‘predict’ eclipses and other celestial events helped priests plan for religious observances.Medicine: the Babylonians pioneered the concept of physical examinations, medical diagnosis and dispensing medicine by prescription.Logic and rationality featured heavily in medicine as in other aspects of life, including agriculture.Mesopotamia is called the cradle of civilization because it was there that the first societies took root and grew.Their knowledge and skill at planting and harvesting crops, directing water where it was needed and developing the skills needed to advance civil living â€" glass-making, textile weaving and water storage, made it possible for humankind to form nation-states, political systems, laws and religions.And, thanks to their skill at metalworking, more deadly weapons were designed, ensuring that warfare would continue to be a part of the human legacy.How do the Mesopotamian accomplishments com pare to those of other ancient civilisations?

What are the High School English Courses

What are the High School English Courses Throughout your high school career, you are expected to fulfill a variety of English course requirements. Some may help you satisfy requirements at the college level, some will assist you in exploring creative writing, and some may simply help you develop the necessary skills to write successfully in the workplace. Like science courses and math courses, English coursework is typically divided up throughout your high school years. While every school and every students schedule are different, lets take a look at a basic guideline Freshman Language Arts During your ninth grade year, you will likely take a class referred to as Language Arts. The scope of this class is typically broad, designed to introduce young learners to the reading, writing, and critical thinking skills that will be necessary later in life. This course (and courses like these) will allow you to practice your writing skills in a variety of essays, explore a range of literary genres, and examine texts at a fairly granular level. Youll look at plot, voice, tone, characters, and so on. Sophomore Language Arts In a sophomore Language Arts class, you can expect to build upon the skills you learned in ninth grade. Youll likely focus a little more on the process of revision, employing practices like outlining and writing drafts as you develop your writing. You may also delve a little deeper into the texts youre reading, which will span even more literary genres. Expect to analyze theme, symbolism, imagery, etc. American Literature Your junior year of English coursework may focus on American Literature, though youll continue to build upon the reading and writing skills you focused on during your freshman and sophomore years as well. In terms of writing, expect to begin researching and incorporating outside sources into your essays. Youll be using context in your exploration of American Literature, too historical context, point of view, time period, and more. British/World Literature During your senior year of high school, you may broaden the scope of the work youre looking at to include British or even world literature. While you may have mostly focused on works of fiction before, you might now explore more nonfiction and poetry. The works you read will probably increase in complexity. As a writer, youll be expected to provide more in-depth analysis, so make sure youre familiar with a plethora of literary devices. You might also write research papers and other presentations that require more of a thought-out timeline to complete, which is an excellent time to practice your time and project management skills. Honors and AP Classes Many high schools will offer Honors or AP versions of the aforementioned classes, which will adhere to a similar (but more complex) format. Youll become more familiar with the why of writing, exploring why authors make the stylistic choices they do. Honors classes are typically offered during freshman and sophomore years, while AP classes (AP English Language and Composition and AP English Literature and Composition) typically occur during junior and senior years. Electives Elective English classes can vary widely by school, but most high schools offer at least one or two. You might expect to find classes that focus on a particular writer (Shakespeare is a popular one) or a certain genre. You may also find creative writing classes offered, which will involve both reading and writing, though theyll go more in-depth than generic Language Arts classes. Never underestimate the value of strong reading and writing skills. Reading well will help you excel in other subjects, follow directions, and gain an advanced understanding of everything you study. Writing well will allow you to communicate more effectively, understand the motivations of other writers, and present yourself appropriately as a professional later in life. If youre interested in writing, certainly explore your elective options. If youre less reading/writing inclined, find something else that does get you excited about these skills, or consider seeking reading tutoring or writing tutoring. Your future self will thank you!
