The transport of 90Sr , 137Cs and 60Co through disc ceramic -supported liquid membrane impregnated in P5 diluted in toluene was examined. The study of The mass transfer rate, expressed as permeability (P), focused on diffusion through the aqueous layer in the feed solution, the organic layer and the aqueous layer in the stripping solution. The aqueous feed solution speed Homogenizer (300-800 ml/min), carrier concentration…

1.3 The impact of macroeconomic releases on exchange rates Economic releases have an important role in the foreign exchange markets. Indeed, macro announcements produce effects on both returns and volatility. Neely and Dey (2010) show that researchers have long studied the reaction of foreign exchange returns to macroeconomic announcements and by doing so, they are now able to infer how markets react to news and how order flow helps impound public and private information into prices. Also,…

affect the rate of reaction? Problem: What effects does temperature have on the rate of reaction? Purpose: The aim of this investigation is to investigate how changing the temperature of sodium thiosulphate affects the rate of reaction in a chemical reaction. In order to complete this practical the temperature will be changed three times and the rate of reaction will be measured each time. Variables: Independent: -the temperature of the sodium thiosulphate. Dependent: -the rate of…

“With increasing degree of calcification, the concentration of NaOH increases. The relationship between the concentration of NaOH and the factors in the calcified red mud liquor is given by three Equations (16–18): N_NaOH=1.29(N_1 m_1-N_2 (m_2-N_NaOH/1.29) (16) m2 = m1+m1N3 (17) r = 1000/m2…

catalytic rate constant kcat. As a model peptide anilide substrate for hydrolysis SAAPPpNA (N-succinyl-L-alanyl-L-alanyl-L-prolyl-L-phenyl-alanine-p-nitroanilide) was selected. Reaction was observed as a function of time by monitoring increment of absorbance data at 410nm as a result of the p-nitroaniline product formation. Initial reaction rate vo was determined by converting raw absorption data units to moles per second using molar extinction coefficient of the substrate. Reaction rates were…

size as temperature increases. By the same token, the O-P-O angles change as temperature increases, while the P-O bond distances change as temperature increases. This results in a change in size in the structure of PO4 as temperature increases. The equation δ^2 = 2/3 δ0^2 [1 + (1 – ¾ (T – Tc/T0 – Tc))^1/2] can be used here to describe quantitatively how the temperature affects the cell parameter and size, as we have earlier established how temperature affects the tilt angle which affects the…

of Apple stock, 1,000 EE Savings Bonds (with $100 denominations and 4.25% coupon rate) that are five years from their 30-year maturity date, or a combination of both. First, we need to know what 1,000 shares of Wal-Mart stock is currently worth. 1,000 shares of Wal-Mart are currently worth approximately; $74,650. Additionally, we have calculated that the 1,000 Savings bonds (w $100 denominations and 4.25% coupon rate) five years from their 30-year maturity date are worth $107,401.34. Wal-Mart…

11/16/2017 Background Research Chemical kinetics is the research of chemical processes which relates to the mechanisms and rates of chemical reactions (Sciencebuddies). The mechanisms describe variations of each molecule during the chemical action such as which bond is broken, which bond together newly, and how the three-dimensional shape of the chemical changes (Sciencebuddies). The rate of the reaction is measuring the speed of the chemical reactions (Sciencebuddies). Study of chemical…

unlimited short sales are allowed. The investor can decide on selling any short amount of shares anytime. The seventh assumption of the CAPM model is unlimited borrowing and lending at a riskless rate. The investor can decide to lend or borrow any amount of funds desired at the rate of interest equals to the rate for riskless securities. The eighth and ninth assumption of the Capital Asset Pricing Model (CAPM) is that it deals with similarity of expectations. Firstly, investors are assumed to…

with Lactic acid was studied in the presence of Mn(II) at alkaline pH. The reaction followed first order with respect to peroxomonosulphate. The rate of the reaction was studied under pseudo first order condition and found to increases with the [Mn(II)] and lactic acid. Thermodynamic parameters were calculated and reported. Based on the results a rate equation, kinetic scheme and a most probable mechanism has been predicted. Keywords: Alpha hydroxy acid, Lactic acid, Peroxomonosulphate,…
