Stability of oil and fats that show in Basrah city markets

Ali H. Abdul- Kareem and Abdul hadi K. Al-salemi

Journal of Basrah Researches (Sciences), Volume 31, Issue 1, Pages 7-11

The stability of oils and fats show in Basrah city markets was studied by measuring some changes with storage. The acid value was (0.48 – 5.37) mg.KOHgm. Sample for Balady fat and Olive oil respectively. Peroxide value was (4-40) m.eq.peroxide oxygen 1 Kg sample for vita fat and olive oil
Respectively, and the TBA value was (1.07-2.03) Malonaldehyde/1Kg. Sample for Balady fat and Mezan fat respectively, while the saponification number was (195.87-203.13) mg./gm

Ground water in southern Iraq

The southern part of Iraq depends upon ground water as an essential source for irrigation processes. The ground water has studied by estimation of electrical conductivity (EC) a ctions K,Na,Ca , Mg and anions SO4, HCO3 ,Cl concentration for five sites chosen from Safwan, Al zupair and Rumaila for five samples from each wall after one hour pumping the hydrochmical analysis shows that water samples of the study area is variant from sodium chloride to sodium sulfate type and the water classification for irrigation use as a C4S4 exapte station (1) as a C4S2 type.

The Desorption field for Na ions from Ni surface

Distance and screening effects on the adatom’s effective charge are studied within the framework of the time – dependent Anderson – Newns model throughout the chemisorption theory. An analytical formula for the effective charges is used and developed where the repulsion of the two electrons of opposite spins in the adatom is taken into account by means of the correlation energy.
An analytical formulation for the metallic chemisorption energy [1] is also used and developed while the ionic contribution to the chemisorption energy is solved numerically. The chemisorption energies are calculated as a function of distance, screening length and crystallography. The calculated chemisorption energies are extracted to calculate fields desorption using Hump model [1]. The comparison with the behavior of the experimental data gives good agreement.

Corrosion Rates Measurments for Different Metal At Different Environments for Naval Applications

Journal of Basrah Researches (Sciences), Volume 31, Issue 1, Pages 30-41

Corrosion rates have been measured for three types of steel
( Corten steel SPA-H, Carbon steel SA-516 and Carbon steel
SA-283). The experiments carried out by immersion of the
three samples in river and sea waters for eight weeks.
Results obtained that the type SA- 516 corrosive with high degree and more than other types and the lowest one is the SA- 283 , also these samples are more corrosive in the sea water than river water due to corrosion properties of the environments with highly significant at P<0.05 . The microscopical examination for the surfaces of these samples have shown the best type for corrosive resistance is the SA-283

Vinegar Production From Malt Processed In Laboratory

Journal of Basrah Researches (Sciences), Volume 31, Issue 1, Pages 52-57

Malt was processed at laboratory using three varieties of barley used as animal feed. Black barley variety was selected for producing malt vinegar. Moisture, protein and ash of the seeds of this variety were: 6.79%, 11.98% and 3.12% respectively .
Many extracts of malt was prepared and the concentration of 10.5% was choosen. Extraction on 50 Co for 90 minitues was used. Malt vinegar was produced by popular method using filtered and non-filtered extracts. Date vinegar was produced and used as control. Results showed that malt vinegar made from filtered extract malt has better total acidity of 4.8% comparing with 4.3% and 3.83% to nonfiltered malt extract vinegar and control respectively, which they have better colour and flavour comparing with filtered malt extract vinegar.
