objectively create a capital budget which will be in the long-run interest of the school. This year the Board of Trustees have been presented with eight different capital investment options ranging from the women’s locker room to a new wood chip heating system for the school. Each of these capital investment decisions have been carefully considered and ranked in order of priority by the trustees before meeting with the headmaster and faculty. The trustee’s objective is to come to agreement on the

crucible and found the samples’ weight to be 1.19 g and 1.55 g‚ respectively. A Bunsen burner was then set up for the heating of the crucible‚ with a wire triangle on the iron ring ensuring that the wire triangle will hold the crucible in an upright position. After setting up the Bunsen burner we heated the crucible with copper (II) sulfate for around eight minutes. During the heating process we haven’t noticed any splattering or popping of the material. After the 8-minute

Abstract The activity of invertase and the quantification of albumin and casein were performed and analyzed after extraction of the said proteins from their respective sources. Isolation of proteins was initiated by the breakage of the cell wall / membranes in three different ways. Homogenization of invertase‚ albumin and casein were achieved via grinding process‚ addition of 1M acetic acid and acidification by 0.1M hydrochloric acid correspondingly. Extraction of invertase and casein involved

What’s the difference between resistance and resistivity? Resistance is the obstruction offered to the flow of current by a conductor. Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor. So basically‚ resistance is the property of the object (say a copper wire)‚ whereas resistivity is the property of the substance (copper). And so resistance depends upon the properties of the object. Whereas resistivity depends upon the properties of the metal.

Huntsville‚ Al 35899‚ US April 2009.” Abstract In this study‚ a novel design of a Fabry-Perot band pass filter using as low and high index coating materials silicon dioxide (SiO2) and titanium dioxide (TiO2) is presented. Two high reflectance dielectric materials separated by a half wavelength “cavity” which is made up of SiO2 that allows light surrounding the central wavelength (550 nm) to be transmitted partially while the remaining spectrum range outside the bandwidth to be almost totally reflected

orientation of a piezoelectric material during the design and manufacture of a device. There are certain mechanical parameters which plays a great role in piezoelectric effect. 2.2.1 Mechanical Strain The mechanical strain S which results from the application of a stress T is linearly proportional to the compliance S (S-1= Young’s modulus) within the elastic deformation region of the stress-strain curve of the material (below the yield strength )
