need to calculate beta of the company’s stock? eg: returns for co. are -5%‚ 5%‚ 8%‚ 15% and 10% over 5 years. the returns for stock exchange are -12%‚ 1%‚ 6% 10% and 5% for the same 5 years. How to compute the beta of the company’s stock? * 5 years ago * Report Abuse anilwyd Best Answer - Chosen by Asker Bete is measure of Risk. Year 1 Beta = -5/12 = 0.42 Year 2 Beta = 5/1 = 5 Year 3 Beta = 8/6 = 1.33 Year 4 Beta =10/10 = 1 Year 5 Beta = 10/5 = 2 Overall Beta for five Year =

Testing Cell Transportation Across a Membrane Introduction Cells have the amazing ability to transport certain molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live

Hadar‚ also known as Beta Centauri‚ is the 10th brightest stars (11th as viewed from Earth). Hadar is a blue-white super giant in the constellation Centaurus (Cen). In about 4‚000 years‚ the motion of Alpha Centauri‚ who’s proper name is Rigel Kentaurus‚ will carry it close enough to Hadar that they will appear to be a magnificent double star. Because of the distance away from Earth that Alpha and Beta Centauri are (approximately 90 parsecs)‚ they will be an optical double. As they sit today‚ the

produces solid or semisolid foods with significantly lower water content. The concentration of liquid foods has three different methods; evaporation‚ membrane concentration‚ and freeze concentration. Evaporation usages gas liquid phase separation. It has the lowest capital cost and the maximum concentration for freeze concentration is more than 50 Brix. Membrane concentration can be used for separating components of foods on a molecular basis‚ where the foods are in solution and where a solution is separated

. Chemistry helps sustain bacteria by protecting the bacteria from outside organisms in the environment out and keeping the bacteria’s contents intact. The Cell Membrane: Is a phospholipid bilayer that completely surrounds a bacterial cell. Cell membrane acts as a highly selective barrier. This barrier prevents materials from diffusing into and out of the cell. This allows the cell to take up chemicals and nutrients needed for survival while keeping the cell components separated from the environment

The aim of this thesis project is to study in vitro the permeability of amorphous drug systems in different conditions. First‚ three complementary techniques are performed to characterize the crystalline and amorphous form of indomethacin. These techniques include IR spectroscopy‚ Raman spectroscopy and differential scanning calorimetry. Indomethacin is a compound belonging to class II of the BCS and is consequently a poorly water-soluble drug. The limiting step in order to have a good bioavailability

Effects of Tonicity on Cell Membrane Abstract The purpose of this experiment was to determine the effects of tonicity on a cell membrane using red blood cells‚ potato strips and three unknown solutions (A‚ B‚ C). First three slides were prepared containing RBC’s and unknown solutions A‚ B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The
