detrimental to the body; So why is it involved in everyday life? Abstract Sodium carbonate‚ Na₂CO₃‚ commonly known as soda ash is used in the manufacturing of many economically important products such as the manufacturing of glass‚ chemicals‚ paper and detergents. Since sodium carbonate has a strong base‚ it is commonly used to neutralize acidic effects. Soda ash has a high pH in concentrated solutions and can irritate the eyes and skin as well as cause corrosion of the stomach lining if ingested

atrocities against other women? The usual answer is to portray women guards as more like surrogate men (Sarah Helm). Dr. Herta Oberheuser was one of the most cruel‚ gruesome female doctors in Ravensbrück. Dr. Oberheuser ran many different types of experiments‚ but she had two certain ones she focused mainly on. She would test different types of injections on children‚ such as evipen and oil. After waiting until they either died‚ or still may be fully alive and aware she would continue working on them

Jacob Stewart Dr. Wells English 101 20 September 2013 In the 1950’s‚ a series of experiments were performed by psychologist Solomon Asch on the effects peer pressure can have on someone that would otherwise be stalwart in their judgment. In the experiment‚ a group of young men were shown a line with three other lines of various lengths next to it‚ and asked to determine which of three lines matched the length of the first line. There was‚ however‚ a catch: all but one of the men were

“polymer creatures‚” which are the things that are used in experiments about polymers. The polymer creatures‚ made out of two different polymers‚ are both hydrophobic and hydrophilic. This means that while the hydrophilic polymer absorbs water‚ the hydrophobic polymer keeps the shape that the creature was originally in while the water is inside the creature. Another name for this process is osmosis

Story Dr. Heidegger invites to his study four elderly friends to engage in an experiment. Three are men: Mr. Medbourne‚ Colonel Killigrew‚ and Mr. Gascoigne; the fourth is a woman‚ the Widow Clara Wycherly. The study is a dusty‚ old-fashioned room replete with a skeleton in the closet‚ a bust of Hippocrates‚ books and bookcases‚ and a portrait of Sylvia Ward‚ who died fifty-five years before the night of the experiment on the eve of marriage to the doctor after swallowing one of his prescriptions

Objective In this experiment the purpose is to study the period of the pendulum with different masses. Secondly to also study the relationship in the different lengths of the string and how it affects the period. Thirdly to find the different (time) periods in the changes in the arc size. Theory If the pendulum is set ‚ the force of the motion is used to swing back and forth . where the t period is the time the pendulum takes to complete a cycle of oscillation. As t-1/f the complete distance of

Analysis Torque is the ability of force to change the rotational motion of a particle. It is also called the moment of force. It is always specified with regard to the axis of rotation. On the experiment the axis of rotation serves as the model balance. This means that as much as torque is directly proportional with the force applied on a particle‚ it is also dependent on the perpendicular distance of the applied force to the axis of rotation. On the first activity we need to determine
