FOOD ENGINEERING - QUESTION 23.3 : (a) In the measurement of the browning (optical density) of fruit juice at 10 day interval, the following pairs of data are obtained with time t in days and browning or optical density (OD) : t = 0, OD = 0.05; t = 10, OD = 0.071; t = 20, OD = 0.089; t = 30, OD = 0.11; t = 40, OD = 0.128; t = 50, OD = 0.149; t = 60, OD = 0.17. (i) By using Excel or other programs, determine if such browning reaction can be characterised by pseudo zero order kinetics, with strong correlations between the data pairs of t and OD. (ii) When OD = 0.24, the shelf life T of such juice is expired. Calculate the value of T. (b) Let food cost percentage = ( food cost / food sales ) x 100. If total food cost of bread and butter are $25, food cost percentage of bread is 50 % and for butter is 50 %, find the total food sales of bread and butter.

BIOCHEMICAL ENGINEERING INSTRUMENTATION - EXAMPLE 29.4 : The resolution of separation, Rs for chromatography is given by the formula Rs = (difference in retention time) / (average width at the base). In a chromatogram, 3 peaks a, b and c are found. Average widths W at the bases of the solutes are : Wa = 20 s, Wb = 40 s, Wc = 30 s. Resolutions of separation, Rs for solutes b and c in comparison to a are 2 and 4 respectively. The differences in retention times T for b and c in comparison to a are (Tb - Ta) and (Tc - Ta), Ta = Tc - Tb : (a) Form 2 equations involving Rs as a function of Wa, Wb, Wc, Ta, Tb and Tc. (b) Find the values of Ta, Tb and Tc.

ENGINEERING PHYSICS - EXAMPLE 30.4 : (a) Time evolution in Heisenberg picture, according to Ehrenfest theorem is m (d / dt) < r > = < p >, where m = mass, r = position, p = momentum of a particle. If v = velocity, prove that m < v > = < p >. (b) Lande g-factor is given by Gj = Gl [ J (J + 1) - S (S + 1) + L (L + 1) ] / [ 2J (J + 1) ] + Gs [ J (J + 1) + S (S + 1) - L (L + 1) ] / [ 2J (J + 1) ]. If Gl = 1 and under approximation of Gs = 2, prove by calculation that Gj = (3/2) + [ S (S + 1) - L (L + 1) ] / [ 2J (J + 1) ].

I have File 1 occurs 5 times with Employee-ID,Employee-Name,Employee-Dept (EEE and MECH). I have File 2 occurs 10 times with Employee-ID,Employee-Name,Employee-Dept (EEE,CIVIL,CHEMICAL and MECH). In FIle 1 and FIle 2 , for matching Employee-DEPT (Only MECH) , we need to move entire records from file1 to file 2. We should not use 2D array. Your help is needed here.

I applied for a B1/B2 visitor visa in May and went to lagos for the interview although i was going to attend a training programme( Faith internaqtional training school) which was going to last for 5 months. i stated i will be staying in the USA for 5 months and i never lost a passport and have not travelled within the last 5 years but i am married with a son working with the local government and salaRY #180,000 Had all the necessary documents to back up my claims yet i was denied under the 214b sectiion, was issued the blue paper and the VO didnot check any of my documents. I have rebook the appointment again for this month next week although made changes to my previous claim that i lost an old passport with three countries visas, GHANA, PORTUGAL , ROMANIA where i visited sometime ago and got a reissued passport which is not carrying any VISAS as at now and also stated that that i will be staying in the USA for only 10 days as my church which recomended me for the training expect to return after ten days of the spiritual enrichment programme to be ordained a pastor . Do you think my past record could be used against me and what are my chances for getting the Visa now going to the embassy at Abuja ????
