Lindow man also known by his scientific name as Lindow II‚ was discovered in 1984 by two workmen who saw his foot sticking out of a piece of machinery in Lindow Moss in Cheshire England. Through evidence‚ and after a visual examination and scientific investigation‚ archaeologists and historians have been able to draw conclusions about Lindow Man’s life and death. Lindow man was an example of a bog body as he was found in a marshy area. After close visual examination of Lindow Man‚ archaeologists

In the Polaroid design the membrane is a special foil consisting of a Kempton® film coated with gold. The foil is stretched over a V-grooved plate‚ Figure 2.5. The transducer is protected by stainless steel housing. A few models with different housings are available. The sizes of these transducers are the main drawback since they are from 30 up to 45 mm in diameter. A further analysis of this structure and its dynamic features is found in [Attila et. al.‚ 1995]. The piezoelectric transducer is based

2.5. Characterization Methods 1H–NMR and 13C–NMR spectra of HPPP‚ BOMP and HVPA were taken in CDCl3 on Bruker DPX–300 MHz spectrometer using tetramethylsilane (TMS) as an internal standard. FT–IR spectra of the synthesized compounds‚ HPPP‚ BOMP‚ HVPA and photocrosslinked polymers were recorded on Perkin-Elmer system 2000 (4000–400 cm–1) spectrometer‚ using KBr pellets. Medium pressure mercury vapour lamp to the power output of 125W/cm2 was used for the photocrosslinking study. The viscosity of the

The Comparative Analysis of Simple Staining and Gram Staining Techniques by observing E. Coli and S. Pyogenes under the Compound Light Microscope INTRODUCTION: A German bacteriologist‚ Dr. Theodore von Escherich‚ was the first man in 1885 who discovered the bacterium named Escherichia coli‚ which are gram negative and appears in rod shaped. Most kind of bacteria E. Coli does not cause diseases and some strains indeed are beneficial in helping the process of food breaking down in the intestines

The Microscope from the Renaissance The Renaissance was a time period that lasted from the 14th to the 17th century. The word renaissance means time of the great revival of art‚ literature‚ and learning in Europe. The word Renaissance come from French/ Middle French. The reason this time period started is because scientist‚ artist‚ and italian scholars made a cultural movement. The reason this time period ended is because of the reformation protestant. There were many people and inventions that

Introduction Using microscopes allows humans to see things they’ve otherwise would have never seen before‚ like cells. A cell is the basic unit of life. All living things are made of cells. All cells come from preexisting cells through a process called cellular division. There are two types of cells‚ eukaryotes and prokaryotes. Prokaryotes are very simple and small. They are unicellular and have no membrane bound organelles. Their DNA is found directly in the cytoplasm since they have no nucleus

Report Learning How to Use the Compound Light Microscope Introduction: Microscope is an instrument used to grow pictures of little questions that are difficult to see with the unaided eye. The compound light magnifying instrument‚ which will be utilized as a part of this lab movement‚ is an instrument with two focal points and different handles to center the picture. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: • Show the fitting methodology
