Laura Fair Zanzibar essays

Laura Fair Zanzibar essays In her book, Fair describes many significant ways in which people use dress, music, and sport to challenge the inherited social order, and to redefine race, ethnicity, gender, and class. The book covers the time from the end of WWII back to the 1990s. During that time, Zanzibar experienced rapid social changes in the appearance of a large number of immigrants, and the end of slavery. The majority of the book focuses on urban Zanzibar and The political evolution of Zanzibar, in Fair's analysis, is largely a story of a change in identity issues among the people of the country. As the 1800's ended, people in Zanzibar were largely seen interims of old identities of free, well-bred Muslims (mwungwana), or non-Muslim, slave or rural (mshenzi). As the century progressed, there was a desire to be seen as Swahili in the 1910's, and there was a switch to ethnic identification in the 1920s. Get another identity appeared as the title Shiraze became increasingly popular in the 1930s and 1940s. These changes in identity were often marked by many differences in sport, music, and dress were used to challenge (and sometimes even identify) changes to social order, and make new definitions of gender, ethnicity, class, and race. Slavery was abolished by the British in 1896 in the Zanzibar Protectorate. Slaves themselves were a diverse lot, consisting of many different ethnicities from the African mainland, most were poor, some were well-off enough to own slaves themselves. As slavery ended, many former slaves suddenly found themselves without a formalized 'place' in the new Zanzibar, as their often relatively benign patron-client relationship Over time, the former slaves developed a new identity that was largely based on the traditional Swahili culture of the East African coast. Many remained on plantations owned by Arabs, but the majority moved to N'gambo, part of Zanz...

Volumetric Flask Definition in Chemistry

Volumetric Flask Definition in Chemistry A volumetric flask is a type of laboratory glassware used to prepare solutions. A volumetric flask is a flat bottomed bulb with a elongated neck calibrated to hold a set volume at a mark on the neck. The flask may also be called a graduated flask or measuring flask because its mark specifies a precise volume measurement. The mark on the flask neck indicates the volume contained. When emptied, some portion of liquid may remain in the container, so the mark (unlike for a pipette) does not indicate the amount to be dispensed. It should be noted volumetric flasks are calibrated for a particular temperature (usually  20  Ã‚ °C), which is indicated on the label. Most volumetric flasks are either transparent glass or plastic, although some flasks are amber-colored for the preparation of light-sensitive solutions. The mouth of the flask may have either a joint to accommodate a stopper or a screw cap. Volumetric Flask Standards All volumetric flasks are not created equal! There are higher and lower precision flasks. A volumetric flask made to conform to a high standard is a Class A or Class 1 flask. Its tolerance, temperature, precision, and volume will be indicated on the glassware. A Class B flask does not conform to as high a standard and may not include all of this information. Class A flasks are used for analytical chemistry work, while Class B flasks are suitable for most educational and qualitative work.
