the polarity and specific distribution of enzymes throughout the Golgi‚ although further investigation is needed. Individual cisternae have been observed using time-lapse 3D microscopy to contain cis‚ medial‚ and trans resident Golgi enzymes progressively. Pulse-chase experiments have been coupled with the time-lapse 3D microscopy to show that cisternal maturation-progression can account for the rapid secretion of certain proteins. Further investigation is needed utilizing various cellular systems.

scientist Antonie van Leeuwenhoek developed the first known microscope using a single magnifying lens. He was the first person to observe microscopic cells that we now know to be bacteria and blood cells. Leeuwenhoek shared the designs of his microscope‚ as well as his observations‚ with the scientific community. * Around 1655 the English scientist Robert Hooke used van Leeuwenhoek’s ideas and made the first compound light microscope‚ which used more than one lens to magnify an object. He examined

Firearms and Toolmark Identification Firearms analysis is a “discipline mainly concerned with determining whether a bullet or cartridge was fired by a particular weapon”. (Saferstein) Its beginnings can be traced back over one thousand years ago to around 1040 A.D. In China‚ Tseng Kung-Liang published the first recipes for three types of gun powder‚ which were made through a mixture of sulfur‚ charcoal‚ and potassium nitrite. (Hellemans and Bunch‚ 75) These basic elements are important because

Further‚ in order to use the oil immersion objective of the microscope and thereby obtain the greatest degree of magnification‚ it is convenient to use stained preparations rather than wet mounts.1 Although bacteria do not appear greatly different from their
