Aim of the work The determination of the concentrations of acid and base solutions through titration. Used compounds HCl solution with an unknown concentration. NaOH solution with a known accurate concentration, indicators phenolphthalein (ff/pp) and methyl red (mp/mr). Equipment Conical flasks (250 cm3), 2 burettes (25 cm3), pipette (10 cm3). Procedure A. Determining the concentration of a hydrochloric acid solution through titration 1. To determine the concentration of the acid solution take the NaOH solution with a known concentration (the standard solution) and pour it into the burette (α in figure 2.2). See that there are no air bubbles near the tip. Fill the burette until the 0-point of the scale. When measuring the level of the solution keep your eyes at the same level with the liquid level. The lower edge of the liquid level has to be at the 0 calibration mark (see figure 2.1).
Acid Rain Acid rain is any precipitation that is unusually acidic. It possesses elevated levels of hydrogen ions(it has low pH level). Acid rain is caused by emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, which react with water molecules. Distilled water(doesn't contain CO 2), has pH level 7. Liquids with pH level less than 7 are acidic, liquids with pH level greater than 7 are alkaline. Unpolluted rain has a pH level over 5.7, so it is slightly acidic. Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan Causes
Miina Härma Gymnasium Acid Rain Report Compiler: Teisi Timma 8a Teacher: Esther Linask Tartu 2009 Acid Rain Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earth's surface
meters) or more long, distinguished from plants by the absence of true roots, stems, and leaves and by a lack of nonreproductive cells in the reproductive structures. Today, algae are used by humans in many ways; for example, as fertilizers, soil conditioners and livestock feed.[54] Aquatic and microscopic species are cultured in clear tanks or ponds and are either harvested or used to treat effluents pumped through the ponds. Algaculture on a large scale is an important type of aquaculture in some places. Maerl is commonly used as a soil conditioner. Factors incluencing soil microflora 1. Cultural practices (Tillage):Cultural practices viz. cultivation, crop rotation, application of manures and fertilizers, liming and gypsum application, pesticide/fungicide and weedicide application have their effect on soil organism. Ploughing and tillage operations facilitate

prototypical aromatic amine. The largest application of aniline is for the preparation of methylene diphenyl diisocyanate. The majority of aniline serves this market. Other uses include rubber processing chemicals (9%), herbicides (2%), and dyes and pigments (2%). Illustrative of the drugs prepared from aniline is paracetamol. The principal use of aniline in the dye industry is as a precursor to indigo, the blue of blue jeans. Like most volatile amines, it possesses the unpleasant smell of rotten fish. 2.

The main disadvantage of this method was the heat liberation during the electriс current passing through the liquid because that prevented for clear division of factions and led to a blurring of the boundaries between the individual zones. In 1940, D. Philpot suggested to use columns with a density gradient of buffer solutions, and in the 50s years the method has been refined and was developed the device for electrophoresis in density gradient. However, the method was deficient, because after switching off the electric current, formed during electrophoresis zones have "blurred". Subsequent achievements in electrophoresis associated with the stabilization establishment of zones in the solid support medium. So, in
book is 85 to 90 per cent. Yet it is not exhaustive. A foolish secrecy still clothes much of World War II cryptology—though I believe the outlines of the achievements are known—and to tell just that story in full would require a book the size of this. Even in, say, the 18th century, the unexplored manuscript material is very great. Nor is this a textbook. I have sketched a few methods of solution. For some readers even this will be too much; them I advise skip this material. They will not have a full understanding of what is going on, but that will not cripple their comprehension of the stories. For readers who want more detail on these methods, I recommend, in the rear of this book, some other works and membership in the American Cryptogram Association. In my writing, I have tried to adhere to two principles. One was to use primary sources as much as possible
female (imported from Denmark) and a classic red tabby and white male. The result was 1 silver tabbies and 2 silver tabbies with white. At just over 3 months old, this silver and white tabby male developed a large patch of bright red hair on his back which continued to spread. Eventually the whole fur will become amber. The effect of amber during the colour-change stage depends on the original colour - solid black or blue, bicolour or tabby. The cat pictured is not a typical amber as it has the silver gene so the amber effect is overlaid on silver. A non-agouti amber Norwegian forest Cat resembles a silver tabby, but has a distinctive black nose and black paw-pads instead of the pink/reddish nose with black outlining found on conventional silver tabbies. The photo below shows a non-agouti amber. According to Rui Pacheco, although this cat is clearly non-agouti because of the black nose, he has the
Sensitivity can be heightened or blunted by education. It is intertwined with curiosity. An ideal education affords numerous and varied opportunities for students to touch, see, smell, listen, hear; to spark their curiosity. When I was a child the things that pleased me were largely other than the plants which have earned me a living as an adult. For example, I collected postage stamps, played basketball, was fond of listening to music, played all manner of games, but dealt only in a neutral, uninspired fashion with plants. The one thing that was constant and of supreme importance was my love of reading. I don't recall why, but by an early age, say age 9, I was a phenomenal reader of books, a habit that persisted all the way until college. Reading expands one's mind immensely. It fires the imagination, demonstrates grammar, teaches vocabulary, informs, challenges, helps one relax. In some cases it forces the mind to concentrate, as to understand

- thus - so - hence - it follows that - it implies that - we may infer that - etc. Premise(s) indicators Swans must have wings, since they are birds and birds do have wings. The word “since” indicates the premises which are claimed to support the conclusion. Other premise(s) indicators include: - because - for - given that - as - for the reason that - may be inferred from - follows from - etc. Two remarks on indicators: 1. The occurence of an indicator does not suffice. We need to find also an inferential relationship. a. Since yesterday, it did not stop raining (temporal meaning) b. Since it is raining, I will take my umbrella (logical meaning) 2. Sometimes, there are no indicators. It is then necessary to inquire the implicit inferential relationshio between the statements in order to identify what statement follows from the other(s).
pronunciation and shape while not affecting the meaning of the word. For example: morpheme that shows plurality is s. In words cat+plural, bus+plural, man + plural the meaning of the word stays the same but the pronunciation varies between /s/ and /ez/. In the word man the shape of the word changes because its plurality is irregular men. So zero plurality is the allomorph of the plurality morpheme.

Because for them the truth does not matter. 18. Who said the phrase: “man is the measure of all things”? What does this phrase mean? Protagoras, it means that the individual human being, is the ultimate source of value. 19. What was Socrates’ main concern? The truth. 20. Which were the two parts of the Socratic method? He would ask people questions and show that they’re ignorant. Only then the people were ready to learn something. 21. What is “to define” i.e., “to give a universal definition”? To define a thing is to set limits to it. 22. Why it is so important to know the essence of things? If we know the essence, we can truly say what things are. 23. What does Socrates’ famous motto “know yourself” mean? It means that in order to fully understand the world we must first understand ourselves. 24. What is the “areté” and why is it so important for Socrates? Virtue, excellence. For Socrates, areté had a human meaning
According to Ganeshan & Harrison (2001) Supply Chain Management is a "systems approach to managing the entire flow of information, materials, and services from raw materials suppliers through factories and warehouses to the end customer." Supply chain event management (abbreviated as SCEM) is a consideration of all possible occurring events and factors that can cause a disruption in a supply chain. With SCEM possible scenarios can be created and solutions can be planned. Some experts distinguish supply chain management and logistics management, while others consider the terms to be interchangeable. From the point of view of an enterprise, the scope of supply chain management is usually bounded on the supply side by your supplier's suppliers and on the customer side by your customer's customers. Supply chain management is also a category of software products.
companions. Another great stressor for young people is school. There are countless reasons why. They have to fit in to their “pack “ and at the same time learn new imporant and lessimportant information and skills. It also reminds them that life is usually hard and tedious. There are many ways for living a less stressful life. The most popular and also the worst method is to change your bodies chemical composition with legal and illegal substances. That is only a short- term solution and makes the situation even worse, because you become dependant on these substances. But there are other better albeit slower solutions. For example breathing slower and meditating has been found beneficial for stressreilief. Even some foods have been shown to reduce the level of cortisol in our body. Cortisol is a stressinducing hormone that sends signals to the body, when your brain thinks it is in trouble. So the best cure
displays of affection. British also like to be different from others, for example, they'll never give up their habit of driving on the left side of the road. 12. Imagine this situation: you are at home, just about to have lunch, when there is a knock at the door. It is a British friend of yours, not a very close friend, but closer than a mere acquaintance. He or she has come to pay you an unexpected visit. You suggest that your friend comes in and stays for lunch. But your friend is embarrassed to find that he or she has called at a mealtime and refuses invitation. You want to persuade your friend to change his or her mind. Here are two possible ways of doing this": A) Please stay. We don't have much, I'm afraid, but we'd be honoured. Whatever we have is yours. B) This is no trouble at all. There's plenty of food. Don't think twice about it. We're used to people popping in
Moving on, What is clay? (slide 4) Clay is fine-grained, firm earthy material that is plastic when wet and hardens when heated. Clay minerals are size of (point zero one mm)0,01mm. It is consisting primarily of hydrated silicates of aluminum and widely used in making bricks, tiles, and pottery. Clay minerals are typically formed over long periods of time by the gradual chemical weathering of rocks, by low concentrations of carbonic acid and other solvents. These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers. In addition to the weathering process, some clay minerals are formed by hydrothermal activity. Clay deposits may be formed in place as remainder deposits in soil, but thick deposits usually are formed as the result of a secondary sedimentary deposing process. Clay deposits are typically associated with very low energy depositional environments such as large lakes and marine basins. (slide 5)
which it must interface. Similarly, if you will be performing calculations to 32- bit accuracy, you will want to consider a CPU with at least 16- and probably 32-bit word width to make computation easier and faster. Interfaces Be sure that interface conditions that are unusual but normal don’t cause damage to any part of the system. For instance, a microprocessor board may connect to a motor control board with a cable. What happens if the service engineer leaves the cable unplugged and turns the system on? Will the motors remain stationary, or will they run out of control? Make sure that issues like this are addressed. Sample Rate and Aliasing Figure 1.3 shows a sinusoidal input signal and an ADC that is sampling slower than the signal is changing. If the system measuring this system assumed it was measuring a sinusoid of some frequency, it would conclude that it was measuring a sinusoid exactly half the frequency of the real input. This is called aliasing
Appendices to the report contain supporting information with the details needed by a reader who wishes to fully understand the design. While this document describes the general content and organization of a design report, some of the specifics (section headings, length, and format) may be determined by your project client. Before You Begin Some basics that you need to understand before starting to write the report. Definition: A design report documents the solution to a unique problem. Purpose: To communicate the solution to a problem. Audience: Anyone who has to implement your design, understand your design, or reference your design to solve their own problem. Typically, this is the project client. While the client may be familiar with the project, the report is still written as though the client is new to the project because that is the best way to tell the whole story.

transition from introductory to higher-level college work in that subject. The series is accessible to non-specialists and each book clearly motivates and expounds the problems and positions introduced. An orientating chapter briefly introduces its topic and reminds readers of any crucial material they need to have retained from a typical introductory course. Considerable attention is given to explaining the central philosophical problems of a subject and the main competing solutions and arguments for those solutions. The primary aim is to educate students in the main problems, positions and arguments of contemporary philosophy rather than to convince students of a single position.

Your actions trigger the emotions and attitudes that go with them. By the Law of Reversibility, you can actually act your way into feeling in a manner consistent with the action. By acting as if you were already happy, positive, and confident, you soon begin to feel that way on the inside. And your actions are under your direct control, whereas your emotions are not. In and of themselves, the outer aspects of your life are neutral. It is only the meaning that you give to them that determines your attitudes, opinions, emotions, and reactions to them. If you change your thinking about any part of your life, you will change how you feel and behave in that area. And since only you can de- cide what to think, you have the ability to take complete control over your life. ■ QUESTION YOUR BELIEFS The Law of Belief says: Whatever you believe, with conviction, be-
beyond the field of software design and into general social interaction. According to the authors of the latter, there must be at least two key elements present to formally distinguish an actual anti- pattern from a simple bad habit, bad practice, or bad idea: · Some repeated pattern of action, process or structure that initially appears to be beneficial, but ultimately produces more bad consequences than beneficial results, and · A refactored solution that is clearly documented, proven in actual practice and repeatable. Often pejoratively named with clever oxymoronic neologisms, many anti-pattern ideas amount to little more than mistakes, rants, unsolvable problems, or bad practices to be avoided if possible. Sometimes called pitfalls or dark patterns, this informal use of the term has come to refer to classes of commonly reinvented bad solutions to problems. Thus, many candidate anti-patterns

Water pollution is one of the biggest threats to the environment today. There are several sources of water pollution ranging from sewage and fertilizers to soil erosion. The impact of water pollution on wildlife and their natural habitat can be immense. While it may seem like preventing water pollution can be an overwhelming subject to tackle, there are also a number of things that the average person can do to help stop water pollution. Tips on Preventing Water Pollution The best solution for water pollution is prevention. While pollution that has already occurred is a current threat to all life on Earth, attempts to clean it up may cause even more harm.There are several steps that can be taken to help prevent water pollution from getting worse. Keep Machinery in Good Working Order The oil used to lubricate engines in all types of machines needs to be changed regularly. When the oil is changed, it presents a number of environmental hazards if not disposed of properly.
and global levels. Economic impacts can be divided into: Direct impacts – The economic indicators on direct impacts are designed to: measure the monetary flows between the organisation and its key stakeholders; and indicate how the organisation affects the economic circumstances of those stakeholders. The aspects for this section are organised around stakeholder groups. Each aspect includes a monetary flow indicator, which provides an indication of the scale of the relationship between reporting organisation and stakeholder. 8 For example, under suppliers, the monetary flow indicator associated with “cost of all goods, materials, and services purchased” provides information on the scale of flows between the reporting organisation and its suppliers. The performance indicator describes one facet of the economic relationship between the suppliers and the reporting organisation.
