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 fi...
The systematic error: | 2= 41,41 g mol -44,0 g mol|=2,59 g mol The relative systematic error g 2,59 ×100 mol 2= =5,89 g 44,0 mol Kokkuvõte It is possible to find volume and molar masses of gases in laboratory environment. Also you can investigate relationship between temp., volume and pressure. As the errors are less than 10% then the results are acceptable. It is hard to improve the results because gases are not visible.

Bombs that targeted the Boston Marathon on Monday may have been packed in pressure cookers. Three people were killed and more than 170 injured when two bombs exploded near the finish line of Monday's race.FBI Special Agent Richard DesLauriers told a news conference that pieces of nylon had been recovered from the scene, along with fragments of ball bearings and nails that were "possibly contained in a pressure-cooker device".He said they were being sent to the agency's laboratory in Quantico, Virginia, where experts would reconstruct the devices to determine their make-up and components The BBC's Paul Adams, in Boston, says vigils for the victims were held across the city on Tuesday night as Bostonians still wrestled with why anyone would want to attack their much-loved marathon. Associated Press quoted a source close to the investigation as saying that the bombs consisted of explosives placed in 1
Solutions of acids are said to be acidic, and solutions of alkalis are said to be alkaline. If a solution is neutral, it is neither acidic nor alkaline. Indicators are substances that change colour when they are added to acidic solutions or alkaline solutions. You can prepare homemade indicators from red cabbage or beetroot juice - these will help you see if a solution is acidic or alkaline. Litmus and universal indicator are two indicators that are commonly used in the laboratory. Litmus Litmus indicator solution turns red in acidic solutions and blue in alkaline solutions - and it turns purple in neutral solutions. Litmus paper is usually more reliable, and comes as red litmus paper and blue litmus paper. The table shows the colour changes it can make. Red Litmus Blue Litmus Acidic solution Stays red Turns red

black music. Clearly they were little quixotic, but still we crossed our paths and went to the concert together. The show was amazing, I've never felt better! After it was all over, me and my new friends from the 70's went back to Central Park to lay back and feel the pleasant nightlife. I still felt little dizzy from my travel from the future which I kept in secret for the people in the past, and before I could realise I fell asleep. When I woke up again I was back in my laboratory. I don't know if it was real or if it was just a dream, but it was the best trip of my life!
The French education system is split into three stages: primary school (école), secondary school (collège) and high school (lycée). Primary and secondary education is free, neutral, secular and compulsory between the ages of 6 and 16. However, there are some private schools that are not subject to these obligations and particularities of the French education system. Nursery school classes accept toddlers at 2 or 3 years of age, starting in September. The children develop their basic faculties, improve their speaking skills and are introduced to the world of reading and writing, numbers and other key areas of learning. From age 6 to 11, the children attend elementary school which is mixed and freein the case of public (state) schools. The 'collège' accepts all pupils after elementary school without the need to pass an entrance exam. The teaching is structured by subject: French, mathematics, history-geography, 'civics' or civil education...

receivers. In 1875, Bell developed his first version of what came to be known as the telephone. He received a patent for it on March 7, 1876, just after his 29th birthday. Five days later, on March 12, he tested his device, speaking into the phone to his associate, Thomas Watson, when he said, "Mr. Watson, come here. I want to see you." After that this primitive telephone was rapidly improved. Picture on the slaid : Bell's March 10, 1876 laboratory notebook entry describing his first successful experiment with the telephone.

Cells of the immune system respond to stress or injury in many of ways (Benoy & Heels, 1998; Mayer & Watkins, 1998; Brines et al, 1996). They secrete a number of cytokines (signalling protein) such as interleukin-6 (IL-6) which is a pro- inflammatory cytokine that mediates the acute phase response to stress. The cytokine IL-6 is also involved in the regulation of the immune system. It is a sensitive immune response marker for stress in laboratory settings and there is now evidence that psychological stressors and hostile behaviour may increase the production of IL-6 (Maes et.al 1998, Morita et al., 2005, Marsland et al 2008). Elliot and Eisdorfer (1982) distinguished two important dimensions in psychological stressors - duration and course (e.g. discrete vs continuous) and five categories of psychological stress. Amongst these five categories acute stressors such as laboratory challenges (e.g.

unable to physically inspect items before committing to purchase them. Police warned that criminals are using generic stock images to deceive consumers into believing the items they are browsing are authentic. Fake electrical items have been singled-out by authorities as a particular risk. Imitation hair curlers, dryers and straighteners are not subject to the same vigorous safety tests as genuine items with some units prone to overheating, presenting a fire risk. Meanwhile laboratory tests have shown counterfeit perfume often contains poisonous chemicals including cyanide and even human urine, according to investigators. Fake cosmetics such as eyeliner, mascara, lip gloss and foundation have been found to contain toxic levels of chemicals and harmful substances such as arsenic, mercury and lead. The unwanted elements can lead to swelling, rashes and in the most serious cases, lethal poisoning. Consumers using websites to buy fake goods have
I must admit I am a shy person, however, I gladly work in a team. I prefer to listen to the views of others and express mine. In other words, I am always ready to make a compromise for successful collaboration. For instance, during group work, I always have a lot of ideas how the material can be logically presented. Taking into account and respecting the opinions of others, I try each time adjust to the choice of the group, and even ready for improvisation. Regarding the laboratory works, I tend to distribute work so that I was comfortable to work and to my partner. It should be noted that studies is not my only fascination. I am interested in creating things with my own hands. I design invitation cards and ornaments made of plasticine, but alsolove drawing (especially portraits). My interests taught me how to concentrate on work, do work in time and qualitatively. I believe

As another example, an antigen-based heartworm test is the gold standard, antemortem diagnostic test for dogs; however, cats often have low worm burden, unisex worm infestations, or immature worm infestations that are not readily detected by these tests Thus, sensitivity is much lower in cats, and this test would not be appropriate as a gold standard for testing cats. Established reference ranges and interpretation of results are only valid for the methods and the laboratory described. Reference ranges generally represent the range of test results from a subpopulation of healthy patients, and values that apply to 95% of the subjects evaluated are included within the range. Thus, patients who consistently fall slightly outside of the range but do not have progressive changes in their results may be, in fact, normal. Test results should always be interpreted in light of other clinical findings. Additionally, the more tests
On that time he was employed as a summer associate at the Chicago law firm of Sidley Austin. Robinson joined him at group social functions, but declined his initial requests to date. They began dating later that summer. They were married on October 3, in 1992. Their first daughter, Malia Ann, was bron in 1998. Their second daughter, Natasha, was born in 2001. Because of Michelle Obama's employment with the University of Chicago, the Obama daughters attended the private University of Chicago Laboratory Schools. When Obama's famaily moved to Washington, in January 2009, the girls started at the private Sidwell Friends School. Barack Obama as the president of United States of America.

approach. It can be concluded, that companies in a high-technology industry do not necessary produce high-technology products and vice versa. This creates a problem of aggregation. Best Location Most high-tech companies want to locate in cities that have highly ranked universities, institutes, or research centers with expertise in their industries. Universities can assist companies through research partnerships, sharing laboratory space and equipment, providing below-market-cost incubator space, and facilitating tech transfer and commercialization. Considerable high-tech growth has occurred around universities and research centers in San Jose and San Diego, California; Boston; Philadelphia; and Washington, D.C. "Some of the largest pharmaceutical companies in Europe have relocated in U.S. cities to gain access to American research," says Kah. A recent example is Novartis, which recently moved its worldwide research
Marjakogumit hooldavad ja kaitsevad isaskalad. Viljakus kala kohta on umbes 2003900 marjatera. Suguküpsus saabub ümarmudilatel kahe- kuni kolmeaastaselt. Veekogu põhja iseloomu suhtes ümarmudilal erilisi nõudmisi ei ole, kuid kudemisajal eelistab ta kivist põhja, sest ta koeb oma pirnikujulised kleepuvad marjaterad kivide alumisele küljele. Ilmselt esineb kalal ka mudilatele iseloomulik pulmamäng, kuid täpsemalt seda ei teata.(1) Foto 3 ümarmudil autor: Ohio sea grant and stone Laboratory Ümarmudila kahjulikus Ümarmudilat peetakse kahjulikuks põlisliikidele ja ta on tunnistatud invasiivseks liigiks Austrias, Kanadas, Saksamaal, Kasahstanis, Poolas, Usbekistanis ja Ameerika Ühendriikides.

Tundmatu tüve identifitseerimine 1. Makromorfoloogilised tunnused Visuaalselt hindasin tundmatu tüve kolooniaid, kui nad olid kasvanud kuus päeva toiteagaril toatemperatuuril. Tunnused Tundmatu tüvi Koloonia: kuju ümar profiil kerkinud, servajoon kumer konsistents sirge värvus limajas, läikiv valkjas 2. Rakulised omadused Gramreaktiivsuse määramiseks teostasin grami järgi värvimise. Kuigi mikroskoobis vaadates olid enamus lühikesed üksikud (agregeerumata) punased pulgad (etanool pesi kristallvioleti-joodi kompleksi välja), leidus ka osa lillaka tooniga rakke, kes olid samuti lühikesed üksikud pulgad. Täiendavalt tegin KOHi lüüsi testi, mis näitas, et tegemist on siiski gramnegatiivsete rakkudega (tekkis iseloomulik limajas konsistents). Tundmatu tüve liikuvuse uurimise jaoks kasutasin poolvedelat söödet (Hugh-Leifsoni sööde), millesse olin eelnevalt teinud pistekülvi. Külvi...
eines norwegischen Seemanns deutet auf Divergenz von einem gemeinsamen Vorfahren aus den 1940er bis frühen 1950er Jahren hin. Es wird angenommen, dass HIV-1 einige Jahre zuvor auf den Menschen übersprang. · Der genetische Unterschied zwischen HIV-1 und HIV-2 deutet jedoch auch darauf hin, dass diese Subtypen bereits weitaus früher divergierten. · Die Genetikerin Bette Korber vom Los Alamos National Laboratory datierte im Jahre 2000 anhand der Probe von 1959 die erste Übertragung auf etwa das Jahr 1931. · Der Evolutionsbiologe Michael Worobey von der University of Arizona datierte im Jahre 2008 mit Hilfe einer zusätzlichen Probe aus dem Jahre 1960 die erste Übertragung auf die Zeit zwischen 1884 und 1924. Er vermutet dadurch, dass die Gründung der Kolonialstädte dem Virus half, Fuß zu fassen. Mit HIV/AIDS lebende Erwachsene und Kinder (Schätzungen) Globale
It shows actual brain activity and has a higher resolution that PET scans. Experiments with animals are still used a lot because this enables psychologists to study specific biological correlates of behavior using invasive techniques (removing or scarring brain tissue). Prior to the development of modern technology, one of the most common ways to study the brain was case study. Often case studies provide researchers with a situation that they could never ethically reproduce in a laboratory. One of the most famous case studies of how brain damage can affect behavior is the study of Phineas Gage by Dr John Harlow. Gage was in a serious accident, where a metal pole pierced his skull and brain. Luckily he survived, losing vision in his left eye. He had no difficulty with speech or language, but the balance between his intellectual abilities and emotional control had been destroyed. He became highly agitated and irrelevant, often impatient and rude
development during the recent years, although the branch became nearly extinct in the early 1990s after the collapse of the Soviet military industry. The local business climate has been revived thanks to the opening of the plant of the international electronics company Elcoteq in 2000. Engineering products and equipment manufactured in Estonia range from cables, mobile phones and computers to security equipment for cars, laboratory equipment, different hoists and other equipment for different industries. The economic changes of the 1990s had an especially severe effect on the chemical industry as many of the enterprises were oriented to the Soviet military industry and their products became unnecessary after Estonia regained its independence. The principal part of it is constituted by the export of petroleum products from Russia.
e. an index varying on a scale ranging from 5 -which means no pilling- to 1 -which means very severe pilling (see Table 1). 6 TABLE 1. degree of pilling. This method proves to be suitable for predicting the actual behavior of fabrics everyday use only in some specific conditions. For instance, according to the ASME Standard, laboratory test is considered reliable as an indication of relative end-use performance in cases where the difference in abrasion resistance of various materials is large, but they should not be relied upon in prediction of actual wear-life in specific end uses, unless there are data showing the specific relationship between laboratory abrasion tests and actual wear in the intended end-use. According to [2], the main drawback of the subjective methods based on estimation by experts is
affordances. 3 05144023 Nevertheless, one of the most significant problems with Gibson's theory is its inability to explain the Ames distorted room illusion (Gehringer & Engel, 1986). Gibson argues that most mistaken perception occurs in situations very different from those, which exist in the natural environment. However, to suggest that illusions are nothing but laboratory tricks designed to confuse people is not true, since at least some produce effects similar to those found in normal perception. Despite the important differences between Gibson and Gregory's theories, they agree on several points. Both believe that visual perception is mediated by light reflected from surfaces and objects, so we therefore need some kind of physiological system to perceive. They also agree that perception is an active process and that our perceptual experiences
Now they are paying more attention to local audience. 10-12 new plays are staged each year, mostly in the 661-seat big auditorium, but sometimes in the 70-seat small hall. Von Krahl Theatre Von Krahl Theatre was established in 1992. But the leader of the theatre Von Krahl Theatre, first privately-owned theatre, the actual history of this theatre begins earlier and is closely connected to the leader of the theatre Peeter Jalakas. Von Krahl Theatre has two fields of action: laboratory work with a purpose of finding and developing specific acting and theatre tools VAT Theatre VAT Theatre is the oldest independent theatre company in Estonia, it started on October 1, 1987. 15 people work there every day, also numerous designers, performers, musicians, directors, writers and others.

Estonian Economy Estonians earn about half of the average European income, despite the fact that the economic growth during the recent years has been very fast and the differences have been diminishing. Although the extremely vigorous period of economic reforms is now over, the changes that Estonia is presently going through are far more extensive than those in the developed countries. The Estonian economy is diverse industry and transport, as well as commerce and different branches of services are all equally important. Due to the available natural resources Estonian economy largely relies on the branches related to the forest; Estonian energy sector is based on oil shale, a resource quite rare elsewhere in the world. Finland and Sweden are the most important trade partners. The Estonian economy profits significantly from the business generated by more than 2 million tourists a year, most of who...
