Today‚ is my second day in concentration camp #59‚ which goes by the name Sobibor; an extermination camp. (Which is just one type of many different purposed camps‚ including prisons‚ labor‚ and transit camps.) I arrived here yesterday at roughly a quarter to noon‚ with my sickly mother Aliza and two older brothers Adam (17) and David (21). My father was brutally murdered yesterday by one of the many Nazi soldiers who invaded our home. “Eliana‚ sis‚ wake up. Protocol will begin in five minutes

UTAR FHSC1134 Inorganic Chemistry Trimester 3 Experiment 1 ________________________________________________________________________ Title: Investigating the Properties of Period 3 Oxides Aim: To examine the oxides of Period 3 elements and describe their structure and bonding. Introduction: Generally‚ there are oxides of metals and non-metals. Metals burn in oxygen to form basic oxides while non-metals form acidic oxides. Structurally‚ they are covalent or ionic compounds. You are to

Date Performed: June 29‚ 2012 Farrah Belle Barredo Experiment 2 The Cell Membrane Abstract The boundary between any cell and its environment is the plasma membrane‚ composed of a matrix of phospholipid molecules along with a number of different kinds of proteins. Membranes have different properties and a variety of functions‚ in large part determined by the specific proteins within the membrane. This experiment is designed to determine the stress that various factors‚ such as osmotic

Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape

Title of Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction

The experimental samples for the pH concentration experiment were put together by using a 10ml-graduated cylinder to obtain 4ml of each pH buffer to insert into cuvettes‚ a micropipette was then used to obtain 0.5ml of catechol and 0.5ml of the catechol oxidase. The pH buffer was made first to avoid any denaturation of the catechol oxidase. Our positive control for this experiment was pH 7 because that is the pH level of most cell membranes in the cytoplasm (Whitson‚ 2016.) Our negative controls

DOE - Design of Experiment DOE is an approach used to identify factors/steps that are contributing most to an observed variation in product specifications. The classical DOE focuses on identifying the factors that affect the level of a product/process response‚ examining the response and forming the mathematical prediction model. The modern DOE‚ introduced by Genichi Taguchi in early 1980s‚ applies in both product and process development to identify the factors that affect the variability of the

Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the

Conditions of Concentration Camps The medical conditions in concentration camps were very horrable. Many things happened to the prisoners at this camp and most of the worst things happened because of the medical treatments. Throughout all the camps medical experiments were performed on the prisoners. They were not only performed on the jewish but on all different kinds of people that were at the camps. The experiments were for the most part either harsh or deadly. Some of the experiments were as

Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and
