Out of the darkness of the French defeat and capitulation of 1940 rose one of the greatest mass-resistance movements in history. Thousands of French patriots rose up‚ by themselves and in groups‚ and defied Nazi authority. They formed resistance movements that fought the Nazi occupation of France and the collaboration of the Vichy government. The French resistance was detrimental to the success of the Allies during World War II because they played a key role in the D-Day landings and were able to

Jewish Resistance We must first realize that resistance was in no way a survival strategy. Yet‚ even when it seemed obvious that death was near inevitable‚ why did they not put up a fight? This argument is still puzzling to many holocaust historians‚ yet the arguments of Raul Hilberg and Yehuda Bauer offer insight to possible reasons why they did not fight and that resistance was more widespread than most people think. First of all we will look at Raul Hilberg’s “Two Thousand Years

The resistance of a wire Planning:- Introduction: To investigate the resistance of a wire at different lengths to see whether or not a longer wire has a larger resistance than a shorter wire. Apparatus: Wire Voltmeter Ammeter Battery 2 crocodile clips Metre rule Variable resistor Diagram: Variables: Length Thickness Resistance Material The material and diameter of the wire needs to be kept constant to keep the test fair as we are investigating resistance.

Antibiotic Resistance Nicholas J. Ciotti Nova Southeastern University Biology 1510 Professor A. Hirons March 28‚ 2011 Abstract Antibiotic resistance is when microorganisms‚ such as bacteria‚ are able to survive an exposure to antibiotics and these bacteria are now resistant to the effects of these antibiotics. Antibiotic resistance in bacteria has been an issue since antibiotics were discovered. The fact that bacteria can become resistant to our medical treatments such as antibiotics

2012 CYNTHIA C. GONZAGA Date of Submission INSTRUCTOR: ENGR. JAY S. VILLAN‚ MEP-EE Introduction A multitester or multimeter is a device which can be used to gather data about electrical circuits. A basic multitester can measure resistance‚ voltage‚ and continuity; while more advanced versions may be able to provide additional data. This tool can be very useful to have around the house‚ and anyone who plans on doing electrical repairs should most definitely use a multitester for safety

Insulin Resistance “Insulin resistance is a silent epidemic that increases the chance diabetes and heart disease” according to the insulin resistance and pre-diabetes article; the causes and treatments are confusing and not always effective. According to Gerald Reaven‚ M.D.‚ Sixty to Seventy-five million Americans have insulin resistance; however‚ they do not know it. The endocrinology system is still a mystery to most average Americans today. They are not well-informed between the differences

Antimicrobial resistance takes a place when a microorganism develops the ability to resist the action of an antimicrobial. (AVMA) In other words‚ the microorganism progress‚ ways to stay alive and reproduce in the presence of an antibiotic that used to prevent these actions. At this time‚ the process of resistance development is a very difficult process and researchers do not know for sure about what can make a resistance happen. (AVMA) Antimicrobials are spread through the food production systems

Does peaceful resistance to laws positively or negatively impact a free society? I feel it ultimately impacts in a positive way by raising awareness of pertinent issues. Non-violent action tends to win more support than does violence. Peaceful resistance is a method of social change that can employ strategies such as strikes‚ sit-ins‚ boycotts and civil disobedience. One example is of the numerous protests against the petroleum industry to transition to a renewable energy source. We have become so
