Equations

a) Heckel equation In 1961, Heckel proposed the most widely used equation describing pharmaceutical powder behavior in compaction. It was initially used to study the densification of ceramics and its correlation with pressure. It a first order process where powder pores elimination rate is correlated to the number of pores present. The rate of volume reduction increases as the number of pores decrease. Heckel equation relates the density, pressure and the pore fraction of the powder [16],.…

1. If the owner of an apartment complex that caters to KU students offered to make a $10,000 dollar contribution to the Lawrence suicide hotline, if I reduced the number of parking places and benefit the KU bus line the effects could range from very small to very large. If I give into the owner of the apartment complex the suicide hotline has more money and could save more lives. However the students would loose their parking spaces and the apartment complex would become more appealing to them…

A. i) The rate of a reaction is the change of a substance’s concentration per units of time. The reaction rate of an experiment is dependent on many things including concentration, presence of a catalyst, and, most importantly, temperature. Temperature and reaction rate are directly correlated, which means that as one increases, so does the other. It is a general approximation that the rate of a reaction will increase by a factor of two for every 10°C jump in temperature. Increased temperature…

0.20 g of adsorbent was added to 20 mL of 50 mg/L dye solution and Vortex at 150 rpm for various time intervals at 5, 10, 15, 30, 60, minutes. The above steps were repeated using dye concentrations of 100, 150 and 200 mg/L dye solutions. Adsorbent dosage is an important parameter because it determines the capacity of adsorbent for a given initial concentration of dye molecules. Then their % absorbance’s were calculated by spectrophotometer (λmax=410) and thus amount adsorbed were calculated.…

Two violins, one viola, and a cello played Joseph Haydn’s String Quartet, Op. 76, No.3 (Emperor), II in quadruple meter and in the form of one homophonic theme with four polyphonic variations. The theme is introduced by the entire quartet in an conjunct melody that has three unique phrases. The first phrase, “A”, is the first to be introduced and repeated a second time, “A-A”. Phrase “A” moves smoothly from mid to high in ascending and descending conjunct intervals and is repeated. A second…

On 08/30/16 we received a payment request in the amount of $633,451.60 ($617,158.33 LOSS & $16,293.27 LAE) from the broker, AON on behalf of Zurich (ZIC). The Pay Time form is completed & tasked to K.Haniff. Our current outstanding reserve is $1,044,591.03 ($837,699.66 Loss & $206,891.37 LAE) with a total incurred of $2,813,385.09.

A group I belong to would be Subwolfer Studios. Subwolfer Studios is a small video game company that I am attempting to put together in order to program video games for the cell phones and perhaps other platforms. Although I founded the group, each member of the group has their own roles and we each have to fulfil our own roles in order to make the company succeed. Although, we are in the very basic steps of formulating the company at this point, al we really have fully accomplished is a name,…

Lab 1- Hardy Weinberg Godfrey Hardy, a mathematician, and Wilhem Weinberg, a physician in Germany, formulated a probability equation about the frequencies of genes that are inheritable within a gene pool. They analyzed that the frequencies of alleles. Hardy and Weinberg made an equation about genetic variance of a population at equilibrium. They postulated that allele or genes should be stable or equal with no disturbing factors. For a generation be able to remain constant and reach the…

his statement referencing hard science fiction and the universe, it was critical to begin my research and analysis with background information on author Hal Clement, before explaining his statement and the relationship to the theme of “The Cold Equation.” Harry Clement Stubbs, a man of multiple names, used the name Hal Clement when he wrote science fiction stories and is known as a leader, if not the leader of the hard science fiction subgenre. Interestingly, if he wrote a science article, he…

Supply chains that are complex are commonly modeled as linear programs (LPs). They can effectively trade off broad range of criteria. To model FMCG supply chains accurately, one must include discrete aspects of decision making, which requires solving a mixed-integer program (MIP). It has become significantly important for managers, given the widespread use of linear models today, to be able to develop good, efficient models to aid them in the decision-making process. Three important factors;…
